INTRODUCTION Overview Dr. C. Everett Koop, former U.S. Surgeon General, once said, “The best prescription is knowledge.”1 The Agency for Healthcare Research and Quality (AHRQ) of the National Institutes of Health (NIH) echoes this view and recommends that all parents incorporate education into the treatment process. According to the AHRQ: Finding out more about your [child’s] condition is a good place to start. By contacting groups that support your [child’s] condition, visiting your local library, and searching on the Internet, you can find good information to help guide your decisions for your [child’s] treatment. Some information may be hard to find—especially if you don’t know where to look.2 As the AHRQ mentions, finding the right information is not an obvious task. Though many physicians and public officials had thought that the emergence of the Internet would do much to assist parents in obtaining reliable information, in March 2001 the National Institutes of Health issued the following warning: The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading.3 Quotation from http://www.drkoop.com.

Chiari Malformation

Since the late 1990s, physicians have seen a general increase in parent Internet usage rates. Parents frequently enter their children’s doctor’s offices with printed Web pages of home remedies in the guise of latest medical research. This scenario is so common that doctors often spend more time dispelling misleading information than guiding children through sound therapies. The Official Parent’s Sourcebook on Chiari Malformation has been created for parents who have decided to make education and research an integral part of the treatment process. The pages that follow will tell you where and how to look for information covering virtually all topics related to Chiari malformation, from the essentials to the most advanced areas of research. The title of this book includes the word “official.” This reflects the fact that the sourcebook draws from public, academic, government, and peerreviewed research. Selected readings from various agencies are reproduced to give you some of the latest official information available to date on Chiari malformation. Given parents’ increasing sophistication in using the Internet, abundant references to reliable Internet-based resources are provided throughout this sourcebook. Where possible, guidance is provided on how to obtain free-ofcharge, primary research results as well as more detailed information via the Internet. E-book and electronic versions of this sourcebook are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). Hard copy users of this sourcebook can type cited Web addresses directly into their browsers to obtain access to the corresponding sites. Since we are working with ICON Health Publications, hard copy Sourcebooks are frequently updated and printed on demand to ensure that the information provided is current. In addition to extensive references accessible via the Internet, every chapter presents a “Vocabulary Builder.” Many health guides offer glossaries of technical or uncommon terms in an appendix. In editing this sourcebook, we have decided to place a smaller glossary within each chapter that covers terms used in that chapter. Given the technical nature of some chapters, you may need to revisit many sections. Building one’s vocabulary of medical terms in such a gradual manner has been shown to improve the learning process. We must emphasize that no sourcebook on Chiari malformation should affirm that a specific diagnostic procedure or treatment discussed in a research study, patent, or doctoral dissertation is “correct” or your child’s

best option. This sourcebook is no exception. Each child is unique. Deciding on appropriate options is always up to parents in consultation with their children’s physicians and healthcare providers.

Organization This sourcebook is organized into three parts. Part I explores basic techniques to researching Chiari malformation (e.g. finding guidelines on diagnosis, treatments, and prognosis), followed by a number of topics, including information on how to get in touch with organizations, associations, or other parent networks dedicated to Chiari malformation. It also gives you sources of information that can help you find a doctor in your local area specializing in treating Chiari malformation. Collectively, the material presented in Part I is a complete primer on basic research topics for Chiari malformation. Part II moves on to advanced research dedicated to Chiari malformation. Part II is intended for those willing to invest many hours of hard work and study. It is here that we direct you to the latest scientific and applied research on Chiari malformation. When possible, contact names, links via the Internet, and summaries are provided. It is in Part II where the vocabulary process becomes important as authors publishing advanced research frequently use highly specialized language. In general, every attempt is made to recommend “free-to-use” options. Part III provides appendices of useful background reading covering Chiari malformation or related disorders. The appendices are dedicated to more pragmatic issues facing parents. Accessing materials via medical libraries may be the only option for some parents, so a guide is provided for finding local medical libraries which are open to the public. Part III, therefore, focuses on advice that goes beyond the biological and scientific issues facing children with Chiari malformation and their families.

Scope While this sourcebook covers Chiari malformation, doctors, research publications, and specialists may refer to your child’s condition using a variety of terms. Therefore, you should understand that Chiari malformation is often considered a synonym or a condition closely related to the following: ·

Arnold-chiari Malformation

4

Chiari Malformation

·

Cerebellomedullary Malformation Syndrome

In addition to synonyms and related conditions, physicians may refer to Chiari malformation using certain coding systems. The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) is the most commonly used system of classification for the world’s illnesses. Your physician may use this coding system as an administrative or tracking tool. The following classification is commonly used for Chiari malformation:4 ·

741.0 with hydrocephalus

For the purposes of this sourcebook, we have attempted to be as inclusive as possible, looking for official information for all of the synonyms relevant to Chiari malformation. You may find it useful to refer to synonyms when accessing databases or interacting with healthcare professionals and medical librarians.

Moving Forward Since the 1980s, the world has seen a proliferation of healthcare guides covering most illnesses. Some are written by parents, patients, or their family members. These generally take a layperson’s approach to understanding and coping with an illness or disorder. They can be uplifting, encouraging, and highly supportive. Other guides are authored by physicians or other healthcare providers who have a more clinical outlook. Each of these two styles of guide has its purpose and can be quite useful. As editors, we have chosen a third route. We have chosen to expose you to as many sources of official and peer-reviewed information as practical, for the purpose of educating you about basic and advanced knowledge as recognized by medical science today. You can think of this sourcebook as your personal Internet age reference librarian. Why “Internet age”? When their child has been diagnosed with Chiari malformation, parents will often log on to the Internet, type words into a search engine, and receive several Web site listings which are mostly irrelevant or redundant. Parents are left to wonder where the relevant This list is based on the official version of the World Health Organization’s 9th Revision, International Classification of Diseases (ICD-9). According to the National Technical Information Service, “ICD-9CM extensions, interpretations, modifications, addenda, or errata other than those approved by the U.S. Public Health Service and the Health Care Financing Administration are not to be considered official and should not be utilized. Continuous maintenance of the ICD-9-CM is the responsibility of the federal government.” 4

information is, and how to obtain it. Since only the smallest fraction of information dealing with Chiari malformation is even indexed in search engines, a non-systematic approach often leads to frustration and disappointment. With this sourcebook, we hope to direct you to the information you need that you would not likely find using popular Web directories. Beyond Web listings, in many cases we will reproduce brief summaries or abstracts of available reference materials. These abstracts often contain distilled information on topics of discussion. While we focus on the more scientific aspects of Chiari malformation, there is, of course, the emotional side to consider. Later in the sourcebook, we provide a chapter dedicated to helping you find parent groups and associations that can provide additional support beyond research produced by medical science. We hope that the choices we have made give you and your child the most options in moving forward. In this way, we wish you the best in your efforts to incorporate this educational approach into your child’s treatment plan. The Editors

PART I: THE ESSENTIALS

ABOUT PART I Part I has been edited to give you access to what we feel are “the essentials” on Chiari malformation. The essentials typically include a definition or description of the condition, a discussion of who it affects, the signs or symptoms, tests or diagnostic procedures, and treatments for disease. Your child’s doctor or healthcare provider may have already explained the essentials of Chiari malformation to you or even given you a pamphlet or brochure describing the condition. Now you are searching for more in-depth information. As editors, we have decided, nevertheless, to include a discussion on where to find essential information that can complement what the doctor has already told you. In this section we recommend a process, not a particular Web site or reference book. The process ensures that, as you search the Web, you gain background information in such a way as to maximize your understanding.

CHAPTER 1. THE ESSENTIALS ON CHIARI MALFORMATION: GUIDELINES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines on Chiari malformation. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. The great advantage of guidelines over other sources is that they are often written with the parent in mind. Since new guidelines on Chiari malformation can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.

The National Institutes of Health (NIH)5 The National Institutes of Health (NIH) is the first place to search for relatively current guidelines and fact sheets on Chiari malformation. Originally founded in 1887, the NIH is one of the world’s foremost medical research centers and the federal focal point for medical research in the United States. At any given time, the NIH supports some 35,000 research grants at universities, medical schools, and other research and training institutions, both nationally and internationally. The rosters of those who have conducted research or who have received NIH support over the years include the world’s most illustrious scientists and physicians. Among them are 97 scientists who have won the Nobel Prize for achievement in medicine.

10 Chiari Malformation

There is no guarantee that any one Institute will have a guideline on a specific medical condition, though the National Institutes of Health collectively publish over 600 guidelines for both common and rare disorders. The best way to access NIH guidelines is via the Internet. Although the NIH is organized into many different Institutes and Offices, the following is a list of key Web sites where you are most likely to find NIH clinical guidelines and publications dealing with Chiari malformation and associated conditions: ·

Office of the Director (OD); guidelines consolidated across agencies available at http://www.nih.gov/health/consumer/conkey.htm

·

National Library of Medicine (NLM); extensive encyclopedia (A.D.A.M., Inc.) with guidelines available at http://www.nlm.nih.gov/medlineplus/healthtopics.html

·

National Institute of Neurological Disorders and Stroke (NINDS); http://www.ninds.nih.gov/health_and_medical/disorder_index.htm

Among the above, the National Institute of Neurological Disorders and Stroke (NINDS) is particularly noteworthy. The mission of the NINDS is to reduce the burden of neurological disease—a burden borne by every age group, by every segment of society, by people all over the world.6 To support this mission, the NINDS conducts, fosters, coordinates, and guides research on the causes, prevention, diagnosis, and treatment of neurological disorders and stroke, and supports basic research in related scientific areas. The following patient guideline was recently published by the NINDS on Chiari malformation.

What Is Chiari Malformation?7 Arnold-Chiari Malformation is a condition in which the cerebellum portion of the brain protrudes into the spinal canal. It may or may not be apparent at birth. Arnold-Chiari I type malformation usually causes symptoms in young adults and is often associated with syringomyelia, in which a tubular cavity develops within the spinal cord. Arnold-Chiari II type malformation is associated with myelomeningocele (a defect of the spine) and hydrocephalus (increased cerebrospinal fluid and pressure within the brain), which usually This paragraph has been adapted from the NINDS: http://www.ninds.nih.gov/about_ninds/mission.htm. “Adapted” signifies that a passage has been reproduced exactly or slightly edited for this book. 7 Adapted from The National Institute of Neurological Disorders and Stroke (NINDS): http://www.ninds.nih.gov/health_and_medical/disorders/chiari_doc.htm. 6

Guidelines 11

are apparent at birth. Myelomeningocele usually causes paralysis of the legs and, less commonly, the arms. If left untreated, hydrocephalus can cause mental impairment. Either type of Arnold-Chiari Malformation can cause symptoms of headache, vomiting, difficulty swallowing, and hoarseness. Adults and adolescents who are unaware they have Arnold-Chiari I type malformation may develop headache that is predominantly located in the back of the head and is increased by coughing or straining. Symptoms of progressive brain impairment may include dizziness, an impaired ability to coordinate movement, double vision, and involuntary, rapid, downward eye movements.

Is There Any Treatment? Infants and children with myelomeningocele may require surgery to repair protrusion of the meningeal sac into the spinal cord. Hydrocephalus may be treated with surgical implantation of a shunt to relieve increased pressure on the brain. Some adults with Arnold-Chiari Malformation may benefit from surgery in which the existing opening in the back of the skull is enlarged.

What Is the Prognosis? Infants with very severe malformations may have life-threatening complications. Most patients who have surgery experience a reduction in their symptoms. Some patients may experience prolonged periods of relative stability.

What Research Is Being Done? Research supported by the NINDS includes studies to understand how the brain and nervous system normally develop and function and how they are affected by disease and trauma. These studies contribute to a greater understanding of congenital birth defects, such as Arnold-Chiari Malformation, and open promising new doors to potential treatments.

More Guideline Sources The guideline above on Chiari malformation is only one example of the kind of material that you can find online and free of charge. The remainder of this chapter will direct you to other sources which either publish or can help you find additional guidelines on topics related to Chiari malformation. Many of the guidelines listed below address topics that may be of particular relevance to your child’s specific situation, while certain guidelines will apply to only some children with Chiari malformation. Due to space limitations these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in

Guidelines 13

cases where the contact information is provided, contacting the publisher or author directly.

Topic Pages: MEDLINEplus For parents wishing to go beyond guidelines published by specific Institutes of the NIH, the National Library of Medicine has created a vast and parentoriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages.” You can think of a health topic page as a guide to patient guides. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search.

The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and educational guidelines on Chiari malformation and related conditions. One of the advantages of CHID over other sources is that it offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The following was recently posted in this archive: ·

Summary: This booklet, written for patients and their families, provides general information about spina bifida. The types of spina bifida and how they affect the spinal nerves are described. Complications such as Chiari malformation, hydrocephalus, learning disabilities, seizures, and allergies are also discussed. A glossary of medical terms is included.

The NIH Search Utility After browsing the references listed at the beginning of this chapter, you may want to explore the NIH search utility. This allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEBSPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to Chiari malformation. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and parents. Nevertheless, a

CHAPTER 2. SEEKING GUIDANCE Overview Some parents are comforted by the knowledge that a number of organizations dedicate their resources to helping people with Chiari malformation. These associations can become invaluable sources of information and advice. Many associations offer parent support, financial assistance, and other important services. Furthermore, healthcare research has shown that support groups often help people to better cope with their conditions.8 In addition to support groups, your child’s physician can be a valuable source of guidance and support. In this chapter, we direct you to resources that can help you find parent organizations and medical specialists. We begin by describing how to find associations and parent groups that can help you better understand and cope with your child’s condition. The chapter ends with a discussion on how to find a doctor that is right for your child.

Associations and Chiari Malformation In addition to associations or groups that your child’s doctor might recommend, we suggest that you consider the following list (if there is a fee for an association, you may want to check with your child’s insurance provider to find out if the cost will be covered):

Churches, synagogues, and other houses of worship might also have groups that can offer you the social support you need.

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to diseasex. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with diseasex. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about Chiari malformation. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797.

DIRLINE A comprehensive source of information on associations is the DIRLINE database maintained by the National Library of Medicine. The database comprises some 10,000 records of organizations, research centers, and government institutes and associations which primarily focus on health and biomedicine. DIRLINE is available via the Internet at the following Web site: http://dirline.nlm.nih.gov. Simply type in “Chiari malformation” (or a synonym) or the name of a topic, and the site will list information contained in the database on all relevant organizations.

The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “Chiari malformation”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” By making these selections and typing in “Chiari malformation” (or synonyms) into the “For these words:” box, you will only receive results on organizations dealing with Chiari malformation. You should check back periodically with this database since it is updated every 3 months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by specific medical conditions. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “diseasex” (or a synonym) in the search box, and click “Submit Query.”

Online Support Groups In addition to support groups, commercial Internet service providers offer forums and chat rooms to discuss different illnesses and conditions. WebMDÒ, for example, offers such a service at its Web site: http://boards.webmd.com/roundtable. These online communities can help you connect with a network of people whose concerns are similar to yours. Online support groups are places where people can talk informally. If you read about a novel approach, consult with your child’s doctor or other healthcare providers, as the treatments or discoveries you hear about may not be scientifically proven to be safe and effective.

Finding Doctors All parents must go through the process of selecting a physician for their children with Chiari malformation. While this process will vary, the Agency


for Healthcare Research and Quality makes a number of suggestions, including the following:9 ·

If your child is in a managed care plan, check the plan’s list of doctors first.

·

Ask doctors or other health professionals who work with doctors, such as hospital nurses, for referrals.

·

Call a hospital’s doctor referral service, but keep in mind that these services usually refer you to doctors on staff at that particular hospital. The services do not have information on the quality of care that these doctors provide.

·

Some local medical societies offer lists of member doctors. Again, these lists do not have information on the quality of care that these doctors provide.

Additional steps you can take to locate doctors include the following: ·

Check with the associations listed earlier in this chapter.

·

Information on doctors in some states is available on the Internet at http://www.docboard.org. This Web site is run by “Administrators in Medicine,” a group of state medical board directors.

·

The American Board of Medical Specialties can tell you if your child’s doctor is board certified. “Certified” means that the doctor has completed a training program in a specialty and has passed an exam, or “board,” to assess his or her knowledge, skills, and experience to provide quality patient care in that specialty. Primary care doctors may also be certified as specialists. The AMBS Web site is located at http://www.abms.org/newsearch.asp.10 You can also contact the ABMS by phone at 1-866-ASK-ABMS.

·

You can call the American Medical Association (AMA) at 800-665-2882 for information on training, specialties, and board certification for many licensed doctors in the United States. This information also can be found in “Physician Select” at the AMA’s Web site: http://www.amaassn.org/aps/amahg.htm.

Selecting Your Doctor11 When you have compiled a list of prospective doctors, call each of their offices. First, ask if the doctor accepts your child’s health insurance plan and if he or she is taking new patients. If the doctor is not covered by your child’s plan, ask yourself if you are prepared to pay the extra costs. The next step is to schedule a visit with your first choice. During the first visit you will have the opportunity to evaluate your child’s doctor and to find out if your child feels comfortable with him or her.

Working with Your Child’s Doctor12 Research has shown that parents who have good relationships with their children’s doctors tend to be more satisfied with their children’s care. Here are some tips to help you and your child’s doctor become partners:

·

You know important things about your child’s symptoms and health history. Tell the doctor what you think he or she needs to know.

·

Always bring any medications your child is currently taking with you to the appointment, or you can bring a list of your child’s medications including dosage and frequency information. Talk about any allergies or reactions your child has had to medications.

·

Tell your doctor about any natural or alternative medicines your child is taking.

·

Bring other medical information, such as x-ray films, test results, and medical records.

·

Ask questions. If you don’t, the doctor will assume that you understood everything that was said.

·

Write down your questions before the doctor’s visit. List the most important ones first to make sure that they are addressed.

·

Ask the doctor to draw pictures if you think that this will help you and your child understand.

·

Take notes. Some doctors do not mind if you bring a tape recorder to help you remember things, but always ask first.

·

Take information home. Ask for written instructions. Your child’s doctor may also have brochures and audio and videotapes on Chiari malformation.

By following these steps, you will enhance the relationship you and your child have with the physician.

CHAPTER 3. CLINICAL MALFORMATION

TRIALS

AND

CHIARI

Overview Very few medical conditions have a single treatment. The basic treatment guidelines that your child’s physician has discussed with you, or those that you have found using the techniques discussed in Chapter 1, may provide you with all that you will require. For some patients, current treatments can be enhanced with new or innovative techniques currently under investigation. In this chapter, we will describe how clinical trials work and show you how to keep informed of trials concerning Chiari malformation.

What Is a Clinical Trial?14 Clinical trials involve the participation of people in medical research. Most medical research begins with studies in test tubes and on animals. Treatments that show promise in these early studies may then be tried with people. The only sure way to find out whether a new treatment is safe, effective, and better than other treatments for Chiari malformation is to try it on patients in a clinical trial.

The discussion in this chapter has been adapted from the NIH and the NEI: http://www.nei.nih.gov/health/clinicaltrials%5Ffacts/index.htm.

14


What Kinds of Clinical Trials Are There? Clinical trials are carried out in three phases: ·

Phase I. Researchers first conduct Phase I trials with small numbers of patients and healthy volunteers. If the new treatment is a medication, researchers also try to determine how much of it can be given safely.

·

Phase II. Researchers conduct Phase II trials in small numbers of patients to find out the effect of a new treatment on Chiari malformation.

·

Phase III. Finally, researchers conduct Phase III trials to find out how new treatments for Chiari malformation compare with standard treatments already being used. Phase III trials also help to determine if new treatments have any side effects. These trials--which may involve hundreds, perhaps thousands, of people--can also compare new treatments with no treatment. How Is a Clinical Trial Conducted?

Various organizations support clinical trials at medical centers, hospitals, universities, and doctors’ offices across the United States. The “principal investigator” is the researcher in charge of the study at each facility participating in the clinical trial. Most clinical trial researchers are medical doctors, academic researchers, and specialists. The “clinic coordinator” knows all about how the study works and makes all the arrangements for your child’s visits. All doctors and researchers who take part in the study on Chiari malformation carefully follow a detailed treatment plan called a protocol. This plan fully explains how the doctors will treat your child in the study. The “protocol” ensures that all patients are treated in the same way, no matter where they receive care. Clinical trials are controlled. This means that researchers compare the effects of the new treatment with those of the standard treatment. In some cases, when no standard treatment exists, the new treatment is compared with no treatment. Patients who receive the new treatment are in the treatment group. Patients who receive a standard treatment or no treatment are in the “control” group. In some clinical trials, patients in the treatment group get a new medication while those in the control group get a placebo. A placebo is a harmless substance, a “dummy” pill, that has no effect on Chiari malformation. In other clinical trials, where a new surgery or device (not a medicine) is being tested, patients in the control group may receive a “sham treatment.” This treatment, like a placebo, has no effect on Chiari malformation and will not harm your child.

Clinical Trials 29

Researchers assign patients “randomly” to the treatment or control group. This is like flipping a coin to decide which patients are in each group. If you choose to have your child participate in a clinical trial, you will not know which group he or she will be appointed to. The chance of any patient getting the new treatment is about 50 percent. You cannot request that your child receive the new treatment instead of the placebo or “sham” treatment. Often, you will not know until the study is over whether your child has been in the treatment group or the control group. This is called a “masked” study. In some trials, neither doctors nor patients know who is getting which treatment. This is called a “double masked” study. These types of trials help to ensure that the perceptions of the participants or doctors will not affect the study results. Natural History Studies Unlike clinical trials in which patient volunteers may receive new treatments, natural history studies provide important information to researchers on how Chiari malformation develops over time. A natural history study follows patient volunteers to see how factors such as age, sex, race, or family history might make some people more or less at risk for Chiari malformation. A natural history study may also tell researchers if diet, lifestyle, or occupation affects how a medical condition develops and progresses. Results from these studies provide information that helps answer questions such as: How fast will a medical condition usually progress? How bad will the condition become? Will treatment be needed? What Is Expected of Your Child in a Clinical Trial? Not everyone can take part in a clinical trial for a specific medical condition. Each study enrolls patients with certain features or eligibility criteria. These criteria may include the type and stage of the condition, as well as, the age and previous treatment history of the patient. You or your child’s doctor can contact the sponsoring organization to find out more about specific clinical trials and their eligibility criteria. If you would like your child to participate in a clinical trial, your child’s doctor must contact one of the trial’s investigators and provide details about his or her diagnosis and medical history. When participating in a clinical trial, your child may be required to have a number of medical tests. Your child may also need to take medications


and/or undergo surgery. Depending upon the treatment and the examination procedure, your child may be required to receive inpatient hospital care. He or she may have to return to the medical facility for followup examinations. These exams help find out how well the treatment is working. Follow-up studies can take months or years. However, the success of the clinical trial often depends on learning what happens to patients over a long period of time. Only patients who continue to return for follow-up examinations can provide this important long-term information.

Recent Trials on Chiari Malformation The National Institutes of Health and other organizations sponsor trials on various medical conditions. Because funding for research goes to the medical areas that show promising research opportunities, it is not possible for the NIH or others to sponsor clinical trials for every medical condition at all times. The following lists recent trials dedicated to Chiari malformation.15 If the trial listed by the NIH is still recruiting, your child may be eligible. If it is no longer recruiting or has been completed, then you can contact the sponsors to learn more about the study and, if published, the results. Further information on the trial is available at the Web site indicated. Please note that some trials may no longer be recruiting patients or are otherwise closed. Before contacting sponsors of a clinical trial, consult with your child’s physician who can help you determine if your child might benefit from participation. ·

Genetic Analysis of the Chiari I Malformation Condition(s): Syringomyelia; Type I Arnold Chiari Malformation Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: The purpose of this study is to better understand the genetic factors related to the Chiari I malformation. In people with this abnormality, the lower part of the skull is smaller than normal. As a result, the lowest part of the brain, called the cerebellar tonsils, protrudes out of the hole at the bottom of the skull into the spinal canal. This study will try to discover the location of the genes responsible for the malformation. Candidates for this study are: 1) Patients with Chiari I malformation who also have a family member with the abnormality or a family member with syringomyelia (a cyst in the spinal cord that is often associated with the Chiari I malformation). 2) Family members of patients

Clinical Trials 31

with the Chiari I malformation. Participants will have a medical history and physical and neurologic examinations. They will undergo magnetic resonance imaging (MRI) of the brain and cervical (neck) spinal cord to measure the size of the head and determine the presence of the Chiari I malformation and syringomyelia. A small blood sample (about 2 tablespoons) will be drawn for DNA studies relating to the Chiari I malformation.

Benefits and Risks16 What Are the Benefits of Participating in a Clinical Trial? If you are considering a clinical trial, it is important to realize that your child’s participation can bring many benefits: ·

A new treatment could be more effective than the current treatment for Chiari malformation. Although only half of the participants in a clinical trial receive the experimental treatment, if the new treatment is proved to be more effective and safer than the current treatment, then those patients who did not receive the new treatment during the clinical trial may be among the first to benefit from it when the study is over.

·

If the treatment is effective, then it may improve your child’s health.

·

Clinical trial patients receive the highest quality of medical care. Experts watch them closely during the study and may continue to follow them after the study is over.

·

People who take part in trials contribute to scientific discoveries that may help others with Chiari malformation. In cases where certain medical

conditions run in families, your child’s participation may lead to better care or prevention for you and other family members. The Informed Consent Once you agree to have your child take part in a clinical trial, you will be asked to sign an “informed consent.” This document explains a clinical trial’s risks and benefits, the researcher’s expectations of you and your child, and your child’s rights as a patient. What Are the Risks? Clinical trials may involve risks as well as benefits. Whether or not a new treatment will work cannot be known ahead of time. There is always a chance that a new treatment may not work better than a standard treatment. There is also the possibility that it may be harmful. The treatment your child receives may cause side effects that are serious enough to require medical attention. How Is Your Child’s Safety Protected? Clinical trials can raise fears of the unknown. Understanding the safeguards that protect your child can ease some of these fears. Before a clinical trial begins, researchers must get approval from their hospital’s Institutional Review Board (IRB), an advisory group that makes sure a clinical trial is designed to protect your child’s safety. During a clinical trial, doctors will closely watch your child to see if the treatment is working and if he or she is experiencing any side effects. All the results are carefully recorded and reviewed. In many cases, experts from the Data and Safety Monitoring Committee carefully monitor each clinical trial and can recommend that a study be stopped at any time. Your child will only be asked to participate in a clinical trial as a volunteer with your informed consent.

Clinical Trials 33

What Are Your Child’s Rights in a Clinical Trial? If your child is eligible for a clinical trial, you will be given information to help you decide whether or not you want him or her to participate. You and your child have the right to: ·

Information on all known risks and benefits of the treatments in the study.

·

Know how the researchers plan to carry out the study, for how long, and where.

·

Know what is expected of your child.

·

Know any costs involved for you or your child’s insurance provider.

·

Know before any of your child’s medical or personal information is shared with other researchers involved in the clinical trial.

·

Talk openly with doctors and ask any questions.

After your child joins a clinical trial, you and your child have the right to: ·

Leave the study at any time. Participation is strictly voluntary.

·

Receive any new information about the new treatment.

·

Continue to ask questions and get answers.

·

Maintain your child’s privacy. Your child’s name will not appear in any reports based on the study.

·

Know whether your child participated in the treatment group or the control group (once the study has been completed).

What about Costs? In some clinical trials, the research facility pays for treatment costs and other associated expenses. You or your child’s insurance provider may have to pay for costs that are considered standard care. These things may include inpatient hospital care, laboratory and other tests, and medical procedures. You also may need to pay for travel between your home and the clinic. You should find out about costs before committing your child to participation in the trial. If your child has health insurance, find out exactly what it will cover. If your child does not have health insurance, or if your child’s insurance policy will not cover care, talk to the clinic staff about other options for covering the costs.


What Questions Should You Ask before Your Child Participates in a Clinical Trial? Questions you should ask when deciding whether or not to enroll your child in a clinical trial include the following: ·

What is the purpose of the clinical trial?

·

What are the standard treatments for Chiari malformation? Why do researchers think the new treatment may be better? What is likely to happen to my child with or without the new treatment?

·

What tests and treatments will my child need? Will my child need surgery? Medication? Hospitalization?

·

How long will the treatment last? How often will my child have to come back for follow-up exams?

·

What are the treatment’s possible benefits to my child’s condition? What are the short- and long-term risks? What are the possible side effects?

·

Will the treatment be uncomfortable? Will it make my child sick? If so, for how long?

·

How will my child’s health be monitored?

·

Where will my child need to go for the clinical trial?

·

How much will it cost to participate in the study? What costs are covered by the study? How much will my child’s health insurance cover?

·

Who will be in charge of my child’s care?

·

Keeping Current on Clinical Trials Various government agencies maintain databases on trials. The U.S. National Institutes of Health, through the National Library of Medicine, has developed ClinicalTrials.gov to provide the public and physicians with current information about clinical research across the broadest number of medical conditions. The site was launched in February 2000 and currently contains approximately 5,700 clinical studies in over 59,000 locations worldwide, with most studies being conducted in the United States. ClinicalTrials.gov

Clinical Trials 35

receives about 2 million hits per month and hosts approximately 5,400 visitors daily. To access this database, simply go to their Web site (www.clinicaltrials.gov) and search by “Chiari malformation” (or synonyms). While ClinicalTrials.gov is the most comprehensive listing of NIH-supported clinical trials available, not all trials are in the database. The database is updated regularly, so clinical trials are continually being added. The following is a list of specialty databases affiliated with the National Institutes of Health that offer additional information on trials: ·

PART II: ADDITIONAL RESOURCES AND ADVANCED MATERIAL

ABOUT PART II In Part II, we introduce you to additional resources and advanced research on Chiari malformation. All too often, parents who conduct their own research are overwhelmed by the difficulty in finding and organizing information. The purpose of the following chapters is to provide you an organized and structured format to help you find additional information resources on Chiari malformation. In Part II, as in Part I, our objective is not to interpret the latest advances on Chiari malformation or render an opinion. Rather, our goal is to give you access to original research and to increase your awareness of sources you may not have already considered. In this way, you will come across the advanced materials often referred to in pamphlets, books, or other general works. Once again, some of this material is technical in nature, so consultation with a professional familiar with Chiari malformation is suggested.

CHAPTER 4. STUDIES ON CHIARI MALFORMATION Overview Every year, academic studies are published on Chiari malformation or related conditions. Broadly speaking, there are two types of studies. The first are peer reviewed. Generally, the content of these studies has been reviewed by scientists or physicians. Peer-reviewed studies are typically published in scientific journals and are usually available at medical libraries. The second type of studies is non-peer reviewed. These works include summary articles that do not use or report scientific results. These often appear in the popular press, newsletters, or similar periodicals. In this chapter, we will show you how to locate peer-reviewed references and studies on Chiari malformation. We will begin by discussing research that has been summarized and is free to view by the public via the Internet. We then show you how to generate a bibliography on Chiari malformation and teach you how to keep current on new studies as they are published or undertaken by the scientific community.

Federally Funded Research on Chiari Malformation The U.S. Government supports a variety of research studies relating to Chiari malformation and associated conditions. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.17 CRISP Healthcare projects are funded by the National Institutes of Health (NIH), Substance Abuse and Mental Health Services (SAMHSA), Health Resources and Services Administration (HRSA), Food and Drug Administration (FDA), Centers for Disease Control and Prevention (CDCP), Agency for Healthcare Research and Quality (AHRQ), and Office of Assistant Secretary of Health (OASH).

(Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Visit CRISP at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You can perform targeted searches by various criteria including geography, date, as well as topics related to Chiari malformation and related conditions. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore Chiari malformation and related conditions. In some cases, therefore, it may be difficult to understand how some basic or fundamental research could eventually translate into medical practice. The following sample is typical of the type of information found when searching the CRISP database for Chiari malformation: ·

Project Title: ADENOSINE AND THE NEURONAL RESPONSE TO HYPOXIA AND ISCHE Principal Investigator & Institution: Fowler, John C.; Associate Professor; Physiology; Texas Tech University Health Scis Center Health Sciences Center Lubbock, Tx 79430 Timing: Fiscal Year 2000; Project Start 1-JUL-1999; Project End 0-JUN2002 Summary: (Verbatim from the Applicant's Abstract) The long-term goal of this research is to understand the (patho) physiologic role of the inhibitory neuromodulator adenosine in the brain's early resp0onse to stroke. Understanding adenosine's contribution is important because adenosine-based pharmacological interventions show promise in reducing neuronal hypoxic/ischemic injury in a number of animal models [31,34,83,87,117]. The specific focus if this proposal is to extend to an in vivo model of the PI's previous series of studies performed in the in vitro hippocampal slice. These in vitro studies detailed adenosine's substantial mediation of the early reversible depression of synaptic transmission and adenosine's interaction with the anoxic depolarization in response to ischemic-like conditions [39-42,44]. Surprisingly, in spite of an extensive literature describing adenosine's role I in vitro slice preparations [9,24,52,69,89,90,142], there has yet to be, to the best of our knowledge, a demonstration of adenosine's role in vivo. The following specific aims, therefore, focus on examining the contribution of salient observations made in vitro to an in vivo hypoxic/ischemic rat hippocampal model. The following specific aims will be addressed: Specific Aim 1. Determine the role of adenosine receptors in the in the

Studies 41

early hypoxic/ischemic depression of synaptic transmission in vivo. Specific Aim 2. Examine the relationship between adensone receptor activation, inhibition of evoked synaptic potentials and tissue pO2 in vivo. Specific Aim 3. Determine the influence of adenosine receptor activation on development of the anoxic depolarization during extended hypoxia/ischemia in vivo. And, examine adenosine receptor function in the post-ischemic period after the anoxic depolarization. Website: http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen ·

Project Title: DEHYDROASCORBIC ACID AS THERAPY FOR ISCHEMIC STROKE Principal Investigator & Institution: Boyd, Thomas A.; ; Progenics Pharmaceuticals, Inc. 777 Old Saw Mill River Rd Tarrytown, Ny 10591 Timing: Fiscal Year 2001; Project Start 0-SEP-2001; Project End 1-JUL-2003 Summary: adapted from applicant's abstract): A major goal of stroke research is the development of new treatment modalities to limit the extent of brain injury following acute ischemic injury. Ischemic stroke is associated with a rapid increase in free radical content in the brain and a depletion of natural antioxidants such as ascorbic acid. Delivery of ascorbic acid to the site of ischemic injury is limited by its inability to cross the blood-brain barrier. Dehydroascorbic acid, the oxidized form of ascorbic acid, readily crosses the blood-brain barrier via a facilitative transport mechanism and is converted into ascorbic acid after entering the brain. Dehydroascorbic acid has shown preliminary evidence of efficacy in a murine stroke model. This compound thus has significant potential as a therapeutic agent for stroke. The first aim of this Phase I project is to prepare an adequate supply of pure dehydroascorbic acid for testing. As large quantities of pure compound are not presently available, a new preparative, large-scale route will be developed. New analytical methods will be developed for determining the compound's identity and purity and for quantitating levels of unwanted impurities. The second aim is to formulate a convenient and stable solution for injection. This is feasible provided the buffer components are tightly optimized and the stability is confirmed by analytical testing. The final aim is to demonstrate in a small animal model that ehydroascorbic acid decreases neuronal injury after an occlusive infarct. This will be done in the mouse middle cerebral artery occlusion model. Dehydroascorbic acid will be administered intravenously at various doses and intervals following the onset of ischemia, and its effects on infarct volume, neurological function, cerebral blood flow, and mortality will be determined. A significant beneficial effect in this model in comparison with either vehicle or ascorbic acid controls will provide in vivo proof-of concept of the


approach and will confine the value of additional studies of dehydroascorbic acid as a therapeutic agent in ischemic stroke. PROPOSED COMMERCIAL APPLICATIONS: Dehydroascorbic acid is a novel treatment for patients who have suffered an ischemic stroke. Dehydroascorbic acid has a unique ability to enter the brain and to elevate tissue levels of ascorbic acid, a natural antioxidant. This project seeks to demonstrate that dehydroascorbic acid is efficacious in a murine stroke model in the interval of time immediately following an ischemic event, a critical period for patients with ischemic stroke. These studies will support eventual clinical testing of the compound. Website: http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen ·

Project Title: ENHANCED CAROTID BIFURCATION PHANTOM FOR MRI/A Principal Investigator & Institution: Burke, Thomas M.; ; Phantoms by Design 1507 175Th Pl Se Bothell, Wa 98012 Timing: Fiscal Year 2002; Project Start 1-SEP-2000; Project End 1-JAN2003 Summary: (provided by applicant): Non invasive MRI evaluation of the carotid artery wall lumen and blood flow patterns is hampered by the lack of a comprehensive and anatomically correct commercially available flow phantom. The objective of this project is to develop an advanced artificial carotid artery flow phantom for use in developing MRI applications to identify patients at risk for transient ischemic attack or strokes. In Phase I, proof-of-concept was established. Phase II technical aims are selected to systematically expand the knowledge and experience base of key technologies: 1) lumen design, based on image data, 2) wall mechanics, with regional variation, 3) image morphology, including two distinct layers with fibrous cap lesion and 4) fluid motion with custom pulsatile flow pump and experimental results compared to hemodynamic simulations. Prototypes are constructed and evaluated in: academic, clinical and industrial environments to gauge commercial potential and identify key functional requirements for commercial development. Materials and preparations are optimized to obtain precision and stability of parameters on the order of 20 percent over 18 months. A comprehensive flow phantom will be critical for the development, validation and training of medical personnel on using state of the art MRI screening protocols for atherosclerotic carotid artery disease. PROPOSED COMMERCIAL APPLICATION: The magnitude of the clinical need for a non invasive means to identify patients at risk and stage carotid artery surgery is so large and the commercial availability of adequate MRI tools so limited as to create a lucrative market niche for highly advanced

Studies 43

anthropomorphic flow phantoms targeted at cerebrovascular disease. Products developed from this project will address current and future needs in clinical research, QA, and personnel training applications. (See Product Development Plan, pages 45-50).

Project Title: HEMORRHAGIC AND ISCHEMIC STROKE AMONG BLACKS AND WHITES Principal Investigator & Institution: Broderick, Joseph P.; Professor and Chair; Neurology; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2000; Project Start 2-SEP-1992; Project End 1-MAY2003 Summary: (Adapted from Investigator's Abstract) The primary goal of the proposed studies is to identify temporal trends in the incidence rate, causes, treatment and outcome of stroke among a large biracial metropolitan population in Cincinnati. There are 1,299,901 people in the greater metropolitan area, 187,806 of whom are black, a percentage that compares favorably with the U.S. population as a whole. The investigators propose to identify every hospitalized or autopsied and almost all non-hospitalized strokes during 1/1/99 through 12/31/99 at all 19 regional hospitals and 147 outpatient screening sites as per the previous five-year funding period. They will identify and abstract detailed information from the medical record for every potential stroke case (methods identical to their ongoing five-year study). In addition, they plan on contacting 500 new ischemic stroke patients (250 blacksexcluding TIAs) and/or their families, to obtain detailed information concerning prior risk factors, knowledge about stroke, outcome following stroke, and buccal cells and/or blood for genetic material. They will replicate a random digit-dialing telephone surgery of 2000 persons from the general population during the year 2000. The estimated 3000 strokes and 700 TIAs as well as the 2000 surveyed persons from the general population will be used to test the following primary hypotheses. 1) The age, sex, and race-adjusted incidence rate of all first-ever stroke, cerebral infarction, and subarachnoid hemorrhage will decrease and the rate of intracerebral hemorrhage will increase during 1999 as compared to incidence rates during 1988 and 1993/4. 2) The 3-month mortality after stroke will be similar for blacks and whites and unchanged from 1993/94, but functional outcome at 3-months as measured by the Barthel Index, Pfeffer Instrumental Activities of Daily Living Scale, and Medical Outcome Study will be poorer among blacks as compared to whites. The investigators state that the long-term goal of this research is to study


temporal trends in stroke incidence rates, treatment, and outcome and their relationships to the prevalence of environmental and genetic risk factors for stroke as well as to changes in public knowledge of stroke risk factors and warning signs.

Project Title: NEURONAL INJURY AND BLOOD GENOMICS Principal Investigator & Institution: Sharp, Frank R.; Professor and ViceChairman; Neurology; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2002; Project Start 1-JUN-2002; Project End 1-MAY2006 Summary: (Adapted from applicant?s abstract): It is hypothesized that the white blood cell genomic response can be used to deduce the presence of neuronal injury due to acute neurological diseases, and that the blood genomic response patterns can be used to differentiate between the diseases causing the neuronal injury. Our preliminary data using microarray technology show unique patterns of gene expression by lymphocytes of adult rats subjected to ischemic strokes, hemorrhagic strokes, status epilepticus, hypoxia, hypoglycemia and sham-surgeries as compared to untouched controls. The first Aim of this proposal will determine whether short durations of global cerebral ischemia, focal cerebral ischemia (transient ischemic attack), hypoglycemia and seizures produce different white blood cell genomic responses in rats that can be used to differentiate between these conditions hours to days later. The second Aim will determine whether long durations of global ischemia, hypoglycemia and status epilepticus regulate specific genes in white blood cells in response to the diffuse neuronal injury caused by all of these conditions, and whether these genes can serve as indicators of the diffuse neuronal injury. The genomic expression of neutrophils, lymphocytes and whole blood will be examined at various times after cerebral ischemia, insulin-induced hypoglycemia, seizures and status epilepticus. Genes regulated in the different white blood cells by these conditions will be correlated with the presence of diffuse neuronal cell death in brain using TUNEL staining. The third set of Aims will determine whether the same genes regulated in white blood cells of rodents following single seizures and status epilepticus are also regulated in the white blood cells of men and women patients following seizures and status epilepticus. These studies will also determine whether blood genomic responses can be used to distinguish whether patients have had seizures, pseudoseizures or syncope, and whether some of the neuronal injury-related genes regulated in the blood of rodents with status

Studies 45

epilepticus are regulated in patients with status epilepticus. Genes regulated more than two fold on microarrays will be confirmed by quantitative RT-PCR for all of the aims. The goal is to objectively differentiate seizures, syncope, global cerebral ischemia, hypoglycemia, and transient ischemic attacks hours to days after they occur; and to begin to identify blood genomic markers of neuronal death associated with acute neurological diseases that might also be useful in chronic neurological diseases.

Project Title: PILOT STUDY OF TNK-TPA IN ACUTE ISCHEMIC STROKE Principal Investigator & Institution: Haley, Elliot C.; Professor; Neurology; University of Virginia Charlottesville Box 400195 Charlottesville, Va 22904 Timing: Fiscal Year 2002; Project Start 1-DEC-1999; Project End 0-NOV2003 Summary: Ischemic stroke continues to be a major public health problem exacting billions of dollars from society in medical care costs and lost wages, as well as incalculable suffering to victims and their families. Recently, thrombolytic therapy with intravenous recombinant tissue plasminogen activator (rt-PA) was shown to improve neurological and functional outcome in patients with acute ischemic stroke who could be treated with 3 hours of onset. However, the risk of symptomatic intracranial hemorrhage complicating rt-PA treatment was 6.4%, and 39% of patients either died or were severely disabled despite treatment. A novel, second generation thrombolytic drug, TNK-TPA, has been specificity engineered to be more fibrin specific than rt-PA, and has been shown in experimental models of thrombosis to be more potent and active more quickly than rt- PA. In experimental stroke, cerebrovascular clots were lysed more quickly, and the incidence of intracranial hemorrhage was reduced. In human studies of myocardial infarction, the drug is well tolerated, and the incidence of intracranial hemorrhage complicating treatment is not greater, and may be less than that with rtPA. This proposal describes a multi-center, open-label, pilot doseescalation safety trial of TNK-TPA in patients with acute ischemic stroke who can be treated within 3 hours. The primary hypothesis to be tested is that TNK-TPA may be safely administered to patients with acute ischemic stroke at doses which may be associated with improvement in neurological outcome. The primary endpoint of the study will be the incidence of symptomatic intracranial hemorrhage within 36 hours of treatment. Safety monitoring and sample size calculations are designed


so that enrollment will cease if the observed intracranial hemorrhage rate exceeds that reported with rt-PA treatment of stroke. Drug activity will be gauged by the proportion of patients with major early neurological improvement as determined by an 8 or more point improvement on the National Institutes of Health Stroke Scale or a perfect score of 0 at 24 hours after stroke onset. Outcome at 3 months will be assessed with the Barthel Index, the modified Rankin Sale, and a global outcome statistic to facilitate sample size calculations for subsequent studies. Sixty to 100 patients will be enrolled in dosage tiers of up to 25 patients each. Website: http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen ·

Project Title: PREDICTORS OF RECURRENT STROKE IN THE PROGRESS STUDY Principal Investigator & Institution: Campbell, Duncan J.; ; St. Vincent's Institute of Med Res 9 Princes St, Fitzroy Victoria, Timing: Fiscal Year 2002; Project Start 0-SEP-2002; Project End 1-AUG2004 Summary: (provided by applicant): The objective is to investigate mechanisms of recurrent stroke. This study is based on plasma samples taken on enrolment from a subset of the 6105 subjects in the perindopril protection against recurrent stroke (PROGRESS) study. The PROGRESS study was a randomized double-blind controlled study of a perindoprilbased blood pressure lowering regimen among individuals with stroke or transient ischemic attack within the previous 5 years. This project has two main aims: 1. To identify whether NMR-determined lipoprotein profiles, and plasma levels of homocysteine, protein carbonyls, chlorotyrosine, soluble vascular cell adhesion molecule (sVCAM-1), C-reactive peptide (CRP), active renin, and the amino-terminal pro-B-type natriuretic peptide (NT-proBNP) predict recurrent stroke in PROGRESS study participants. 2. To identify whether nuclear magnetic resonance (NMR)determined lipoprotein profiles, and plasma levels of homocysteine, protein carbonyls, chlorotyrosine, sVCAM-1, CRP, active renin, and NTproBNP predict benefit from perindopril-based antihypertensive therapy. This will be a nested case-control study. From the plasma samples obtained from 6105 subjects on enrolment in the PROGRESS study, 727 are from subjects who experienced recurrent stroke during the study. Our cases will be the 325 from this 727 from whom plasma samples were collected more than one month after the qualifying event and frozen at 80xC within 24 hours. Each case will be matched to two control subjects who had no cardiovascular event. The data will be related to clinical markers of cardiovascular risk on enrolment. We will determine which of these plasma markers provides an independent measure of risk of

Studies 47

recurrent stroke. In addition, we will determine those plasma markers that provide an independent measure of reduction in risk of recurrent stroke by perindopril-based antihypertensive therapy, thereby providing a means to identify those subjects most likely to benefit from such therapy, and conversely, those subjects in whom alternative preventative strategies are required. In addition, plasma markers that predict risk of recurrent stroke may indicate novel therapies to prevent this condition. Website: http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen ·

Project Title: SOCIOBIOLOGICAL FACTORS IN EXPERIMENTAL STROKE OUTCOME Principal Investigator & Institution: Devries, a C.; Anesthesiology/Crit Care Med; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2000; Project Start 1-JUL-2000; Project End 1-DEC2000 Summary: Both acute and chronic stress can have long-term physiological and psychological consequences, some of which can be ameliorated through positive social interaction. The current proposal will examine the effects of prior exposure to positive social interaction versus social stress on the histological, physiological and behavioral consequences of experimental stroke. In addition, alterations in the corticosteroid, glutamate and antioxidant responses to experimental stroke will be examined as possible mechanisms through which social cues can influence histological and functional outcome in this model. The data collected as part Of this proposal will increase our understanding of the basic pathophysiological mechanism of cerebral ischemia and the roles that social interaction and the hypothalamic-pituitary-adrenal axis play in modulating excitotoxic neuronal death. Ultimately, understanding the factors that modulate neurotoxicity and behavioral outcomes may facilitate the development of therapeutic approaches for the prevention and treatment of cerebral ischemia. Taken together, the proposed studies will provide a neurobiological foundation on which to study the effects of social cues on experimental stroke outcome, and may provide insights into the mechanisms underlying individual differences in outcome following an ischemic event.

Project Title: SODIUM IMAGING IS ISCHEMIC HEART DISEASE Principal Investigator & Institution: Bottomley, Paul A.; Russell H. Morgan Professor; Radiology; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218


Timing: Fiscal Year 2000; Project Start 1-JUL-1999; Project End 0-JUN2003 Summary: The exchange of intra- and extra-cellular sodium and potassium ions is essential to cell function and integrity. In the heart, evidence from animal and human radionuclide imaging studies of potassium and potassium analogs, and from biochemical and magnetic resonance spectroscopy (MRS) studies of animal models, indicates that sodium- potassium pump function is compromised during periods of myocardial ischemia and that it is lost in non-viable, infarcted tissue as intra- and extra-cellular pools equilibrate. Sodium (23Na) magnetic resonance imaging (MRI) is uniquely able to image and measure noninvasively naturally abundant, endogenous sodium in the body. 23Na MRI at magnetic fields of > 2.7 Tesla (T) in animal models demonstrate a 2-fold increase in 23Na signal levels in nonviable, histologically-confirmed, acute reperfused myocardial infarction (MI). Owing to its higher tissue concentration and sensitivity and its short relaxation time, 23Na MRI has an enormous sensitivity advantage compared, for example, with the detection of high-energy phosphate metabolites by phosphorus (31P) MRI (approximately 80- fold). Thus 23Na MRI is a potentially unique and important tool for assessing cellular metabolic and ionic function through altered sodium levels in patients with ischemic heart disease and/or MI. Yet 23Na is not now routinely possible on clinical 1.5T MRI scanners. Moreover, human 23Na MRI has never benefitted from new MRI hardware and software technology. In preliminary studies we implemented 23Na MRI on a clinical MRI scanner, and demonstrate altered 23Na MRI levels in MI. We show preliminary stress-23Na MRI data from patients with stressinduced ischemia detected metabolically by 31P MRS. Here we propose to develop and optimize human cardiac 23Na MRI on a clinical 1.5 T MRI/MRS system, by implementing high-speed MRI, 23Na phased-array detection, resolution-enhancement using a priori anatomic information, and methods of suppressing 23Na signals from ventricular blood. We will use optimized 23Na MRI to characterize normal and infarcted human myocardium, and to test the hypotheses that 23Na MRI can differentiate normal from non-viable reperfused MI in patients as detected by radionuclide imaging, and compared with contrastenhanced MRI. Further, the hypothesis that optimized 23Na MRI can detect stress-induced changes in sodium in energetically- compromised myocardium will be tested in combined stress-23Na/3 1P metabolic studies. The availability of thousands of clinical MRI scanners offers a great opportunity for advancing 23Na MRI as a tool for assessing sodium pump function in human heart disease.

Project Title: STRESS AND MYOCARDIAL MECHANISMS AND TREATMENT

ISCHEMIA--

Principal Investigator & Institution: Blumenthal, James A.; Professor of Medical Psychology; Psychiatry and Behavioral Scis; Duke University Durham, Nc 27706 Timing: Fiscal Year 2000; Project Start 5-SEP-1998; Project End 1-AUG2003 Summary: (adapted from the applicant's abstract): The presence of transient myocardial ischemia is an important functional expression of coronary heart disease (CHD). Recent research has shown that mental stress can trigger ischemia in the laboratory and during daily life, and that mental stress-induced ischemia is associated with increased risk for coronary events over and above exercise-induced ischemia. The present study is designed to examine the extent to which a program of exercise or stress management training reduces ischemic activity measured in the laboratory using radionuclide ventriculography and during daily life using ambulatory monitoring. In addition, we propose to examine the bio-behavioral mechanisms by which mental stress triggers ischemia, and the mechanisms by which the inter-ventions reduce ischemic activity. Two hundred and ten patients with documented CHD and evidence of exercise-induced myocardial ischemia will serve as subjects for this study. Patients will be withdrawn from anti-ischemic medications and undergo comprehensive evaluations both in-hospital and out-of-hospital. In-hospital assessments will include provocative mental stress testing to elicit myocardial ischemia, ultrasound testing to assess endothelial function, and psychometric testing to assess underlying personality traits and behavioral dispositions. The out-of-hospital assessment will consist of 48-hour ischemia monitoring with concurrent blood pressure monitoring and behavioral diary recording. Following completion of the assessments, patients will resume their usual medications and will be randomly assigned to either Aerobic Exercise, Stress Management or Education/Routine Care. Patients will be re-evaluated after the fourmonth treatment program and thereafter followed for at least six months. It is hypothesized that exercise and stress management training will be associated with a reduction in ischemic activity, associated with reductions in blood pressure and systemic vascular resistance, and improved endothelial function. Data from this study will provide new scientific insights into the mechanisms of stress-induced myocardial ischemia, as well as important knowledge regarding the clinical benefits


of exercise and stress management training in the treatment of CHD patients with myocardial ischemia. Website: http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen ·

Project Title: STROKE OUTCOME AND NEUROIMAGING OF INTRACRANIAL STENOSIS Principal Investigator & Institution: Feldmann, Edward; Associat Professor; Rhode Island Hospital (Providence, Ri) 593 Eddy St Providence, Ri 02902 Timing: Fiscal Year 2000; Project Start 5-SEP-1999; Project End 0-JUN2004 Summary: Intracranial atherosclerosis is responsible for 50,000 ischemic strokes each year in the USA. Noninvasive testing such as transcranial Doppler ultrasound (TCD) and magnetic resonance angiography (MRA) to identify intracranial atherosclerosis is in widespread use but has not been rigorously validated against the gold standard, catheter angiography. The recently NIH-funded WASID trial (Warfarin Aspirin Symptomatic Intracranial Disease) will compare warfarin with aspirin for stroke prevention in patients with intracranial atherosclerosis. WASID requires performance of angiography along with TCD and MRA, providing an opportunity to critically evaluate these nonivasive tests. Main Objective. The purpose of SONIA is to validate the noninvasive diagnosis of intracranial atherosclerosis. The primary aim of SONIA is to define velocity values on TCD and anatomic abnormalities on MRA that identify severe (50-99 percent) intracranial stenosis or large, proximal arteries seen on catheter angiography. SONIA will define the criteria, or cutpoints, for an abnormal TCD or MRA and show that they perform with a reliable positive predictive value (PPV). Study Design. SONIA will be conducted in collaboration with WASID. Study-wide cutpoints defining positive TCD and MRA have been developed and reviewed by the site investigators of WASID. Hard copy angiography, TCD and MRA generated in WASID will be centrally read in SONIA. The performance of TCD and MRA will be monitored and analyzed in SONIA to demonstrate cutpoints that achieve a PPV of 80 percent for the identification of severe intracranial stenosis on angiography. Conclusions. Central readings will be used to validate the cutpoints that function with a PPV of 80 percent and to develop measures of negative predictive value (NPV), inter- and intra-observer variability. Sensitivity and specificity will be determined after adjustment for verification bias and employed in receiver-operator characteristic analyses. SONIA will use these techniques to develop TCD or MRA cutpoints that minimize the clinical consequences of test errors

Project Title: TIA-INDUCED ISCHEMIC TOLERANCE VIA P450 EPOXYGENASE Principal Investigator & Institution: Alkayed, Nabil; Anesthesiology/Crit Care Med; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 1-JUN-2002; Project End 0-APR2006 Summary: (provided by applicant): The project seeks to determine if prior exposure to mild ischemia, such as occurs during Transient Ischemic Attack (TIA), alters the brain's response to subsequent stroke by serving as a preconditioning stimulus and triggering neuroprotective mechanisms. Specifically, we will test the hypothesis that experimental TIA reduces damage from subsequent stroke by a mechanism that involves upregulation of cytochrome P450 2C11, a P450 AA epoxygenase expressed in astrocytes, which catalyzes the conversion of arachidonic acid (AA) to biologically active epoxyeicosatrienoic acids (EETs). The Specific Aims of the project are: 1) To determine if experimental TIA protects brain from subsequent stroke by EETs-mediated mechanism, 2) To determine if TIA-enhanced EETs production is due to upregulation in astrocytes of the biosynthetic enzyme P450 2C11, 3) To determine if genetic and pharmacological manipulations of EETs synthetic and breakdown pathways mimic the protection acquired by TIA, and 4) To determine if ischemic tolerance in TIA-preconditioned brain is due to EETs-mediated activation of phosphoinositide 3-kinase (P13-K) /Akt cell survival signaling cascade in neurons. To simulate TIA, three 10-minute periods of middle cerebral artery occlusion (MCAO) will be induced in


rats and mice; three days later, a more severe 2-hour ischemia is produced and infarct size is measured at 1 and 7 days to assess short- and long term tissue outcome after stroke. The level of endogenous EETs in brain will be manipulated using pharmacological and genetic tools and measured using in-vivo microdialysis. Expression of P450 2C11 will be examined using RNase protection assay, Western blotting, immunohistochemistry and in-situ hybridization. Western blotting with anti-phospho-Akt antibody will assess Akt activation and the importance of this pathway to ischemic tolerance will be evaluated using specific P13-K/Akt inhibitors. The studies explore a potential endogenous mechanism of protection from cerebral ischemia, which can be targeted as a novel strategy for stroke injury prevention and treatment.

Project Title: WARFARIN/ASPRIN INTRACRANIAL DISEASE STUDY

SYMPTOMATIC

Principal Investigator & Institution: Chimowitz, Marc I.; ; Emory University 1380 S Oxford Rd Atlanta, Ga 30322 Timing: Fiscal Year 2001; Project Start 1-OCT-1974; Project End 0-NOV2004 Summary: The purpose of this study is to compare the efficacy and safety of warfarin (INR 2-3) with high dose aspirin (1300 mg per day) for preventing stroke and vascular death in patients with transient ischemic attack or non-server stroke caused by symptomatic stenosis of a major intracranial artery.

Project Title: WOMENS ESTROGEN FOR STROKE TRIAL Principal Investigator & Institution: Horwitz, Ralph I.; Internal Medicine; Yale University New Haven, Ct 06520 Timing: Fiscal Year 2000; Project Start 1-JUN-1993; Project End 1-JUL2002 Summary: The Women's Estrogen for Stroke Trial (WEST) is a randomized, double- blind, placebo-controlled trial testing whether estrogen treatment, compared to placebo, reduces the risk of death or recurrent stroke in postmenopausal women with a transient ischemic attack or first nondisabling stroke. Patient accrual, which began in December 1993, was based on a sample size target of 652 women to detect a difference in endpoints of 10 percent (25 percent in placebo group and 15 percent in estrogen group). To date, the WEST has enrolled 561 patients and has been remarkably successful in maintaining high protocol

adherence, patient participation, and clinical safety. Enrollment in WEST will be completed by May 31, 1998, before the start of the continuation period. Therefore, the principal aim for the competing renewal is to complete the WEST as originally proposed to ensure desired average length of patient follow-up of 3.5 years and to permit the necessary data management and analysis. The additional funded time is also needed to enable the trial investigators to arrange for appropriate termination of subject participation. A second aim for the competing renewal is to acquire new data about the clinical course and outcomes of TIA and nondisabling stroke in elderly women, and on the impact of estrogens generally in this special population. Indeed, few studies have had the opportunity to acquire detailed clinical, behavioral and cognitive data on the clinical course of stroke in a group of women this age who began their participation with high levels of functional independence. The goals of WEST are even more salient to the health of American women today than when they were proposed in 1992. Even now in 1997 no clinical trial data are available demonstrating estrogen's effect on vascular endpoints, including cerebrovascular, that would help postmenopausal patients and their physicians decide whether and when to use estrogens. Thus, the results of WEST promise to provide American women with urgently needed information that may help to reduce the risk of stroke and strokerelated mortality.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine. The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to the public.18 If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with Chiari malformation, simply go to the PubMed Web site at www.ncbi.nlm.nih.gov/pubmed. Type “Chiari malformation” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for “Chiari malformation” (hyperlinks lead to article summaries): ·

CHAPTER 7. PERIODICALS AND NEWS ON CHIARI MALFORMATION Overview Keeping up on the news relating to Chiari malformation can be challenging. Subscribing to targeted periodicals can be an effective way to stay abreast of recent developments on Chiari malformation. Periodicals include newsletters, magazines, and academic journals. In this chapter, we suggest a number of news sources and present various periodicals that cover Chiari malformation beyond and including those which are published by parent associations mentioned earlier. We will first focus on news services, and then on periodicals. News services, press releases, and newsletters generally use more accessible language, so if you do chose to subscribe to one of the more technical periodicals, make sure that it uses language you can easily follow.

News Services and Press Releases Well before articles show up in newsletters or the popular press, they may appear in the form of a press release or a public relations announcement. One of the simplest ways of tracking press releases on Chiari malformation is to search the news wires. News wires are used by professional journalists, and have existed since the invention of the telegraph. Today, there are several major “wires” that are used by companies, universities, and other organizations to announce new medical breakthroughs. In the following sample of sources, we will briefly describe how to access each service. These services only post recent news intended for public viewing.


PR Newswire Perhaps the broadest of the wires is PR Newswire Association, Inc. To access this archive, simply go to http://www.prnewswire.com. Below the search box, select the option “The last 30 days.” In the search box, type “Chiari malformation” or synonyms. The search results are shown by order of relevance. When reading these press releases, do not forget that the sponsor of the release may be a company or organization that is trying to sell a particular product or therapy. Their views, therefore, may be biased.

Reuters Health The Reuters' Medical News and Health eLine databases can be very useful in exploring news archives relating to diseasex. While some of the listed articles are free to view, others can be purchased for a nominal fee. To access this archive, go to http://www.reutershealth.com/en/index.html and search by “diseasex” (or synonyms).

The NIH Within MEDLINEplus, the NIH has made an agreement with the New York Times Syndicate, the AP News Service, and Reuters to deliver news that can be browsed by the public. Search news releases at http://www.nlm.nih.gov/medlineplus/alphanews_a.html. MEDLINEplus allows you to browse across an alphabetical index. Or you can search by date at the following Web page: http://www.nlm.nih.gov/medlineplus/newsbydate.html. Often, news items are indexed by MEDLINEplus within their search engine.

Business Wire Business Wire is similar to PR Newswire. To access this archive, simply go to http://www.businesswire.com. You can scan the news by industry category or company name.

Periodicals and News 97

Market Wire Market Wire is more focused on technology than the other wires. To browse the latest press releases by topic, such as alternative medicine, biotechnology, fitness, healthcare, legal, nutrition, and pharmaceuticals, log on to Market Wire’s Medical/Health channel at the following hyperlink http://www.marketwire.com/mw/release_index?channel=MedicalHealth. Market Wire’s home page is http://www.marketwire.com/mw/home. From here, type “diseasex” (or synonyms) into the search box, and click on “Search News.” As this service is technology oriented, you may wish to use it when searching for press releases covering diagnostic procedures or tests.

Search Engines Free-to-view news can also be found in the news section of your favorite search engines (see the health news page at Yahoo: http://dir.yahoo.com/Health/News_and_Media/, or use this Web site’s general news search page http://news.yahoo.com/. Type in “Chiari malformation” (or synonyms). If you know the name of a company that is relevant to Chiari malformation, you can go to any stock trading Web site (such as www.etrade.com) and search for the company name there. News items across various news sources are reported on indicated hyperlinks.

BBC Covering news from a more European perspective, the British Broadcasting Corporation (BBC) allows the public free access to their news archive located at http://www.bbc.co.uk/. Search by “Chiari malformation” (or synonyms).

Newsletter Articles If you choose not to subscribe to a newsletter, you can nevertheless find references to newsletter articles. We recommend that you use the Combined Health Information Database, while limiting your search criteria to “newsletter articles.” Again, you will need to use the “Detailed Search” option at http://chid.nih.gov/detail/detail.html. Go to the bottom of the search page where “You may refine your search by.” Select the dates and language that you prefer. For the format option, select “Newsletter Article.”


By making these selections, and typing in “Chiari malformation” (or synonyms) into the “For these words:” box, you will only receive results on newsletter articles. You should check back periodically with this database as it is updated every 3 months. The following is a typical result when searching for newsletter articles on Chiari malformation: ·

Headaches in Ehlers-Danlos Syndrome Source: Loose Connections. XV(3): 1,4-8. September-October 2000. Contact: Available from Ehlers-Danlos National Foundation. 6399 Wilshire Blvd., Suite 510, Los Angeles, CA 90048. (323) 651-3038. Summary: This newsletter article provides health professionals and people who have Ehlers-Danlos syndrome (EDS) with information on a study that investigated the occurrence of chronic headaches in this complex hereditary connective tissue disorder. Data were obtained from 18 patients with EDS and chronic headaches. All of the patients were seen in a rural practice setting and were followed for a minimum of 2 years. Procedures included clinical history taking, neurologic examination, computerized tomography of the head, magnetic resonance imaging of the brain, and electroencephalogram (EEG). Headaches were classified according to the International Headache Society. The study found that four patients had migraine with aura, four had migraine without aura, four had tension headaches, four had a combination of migraine and tension headaches, and two had posttraumatic headaches. Nine patients exhibited blepharoclonus, but none had a history of seizures and their EEGs were normal, ruling out eye closure epilepsy. Although one patient had a small right frontal angioma, a second had Arnold Chiari malformation type I, and a third had an old stroke, headaches did not clinically correlate with their central nervous system (CNS) lesions. The article concludes that chronic recurrent headaches may constitute the neurologic presentation of EDS in the absence of structural, congenital, or acquired CNS lesions that correlate with their symptoms. People who have EDS may be prone to migraine due to an inherent disorder of cerebrovascular reactivity or cortical excitability. Additional studies are needed to elucidate the pathogenesis of headaches in EDS. 1 table and 5 references. (AA-M).

While all of the above references may be of interest to physicians who study and treat Chiari malformation, the following are particularly noteworthy.

The NLM Gateway22 The NLM (National Library of Medicine) Gateway is a Web-based system that lets users search simultaneously in multiple retrieval systems at the U.S. National Library of Medicine (NLM). It allows users of NLM services to initiate searches from one Web interface, providing “one-stop searching” for many of NLM’s information resources or databases.23 One target audience for the Gateway is the Internet user who is new to NLM’s online resources and does not know what information is available or how best to search for it. This audience may include physicians and other healthcare providers, Adapted from NLM: http://gateway.nlm.nih.gov/gw/Cmd?Overview.x. The NLM Gateway is currently being developed by the Lister Hill National Center for Biomedical Communications (LHNCBC) at the National Library of Medicine (NLM) of the National Institutes of Health (NIH).

HSTAT25 HSTAT is a free, Web-based resource that provides access to full-text documents used in healthcare decision-making.26 HSTAT’s audience includes healthcare providers, health service researchers, policy makers, insurance companies, consumers, and the information professionals who serve these groups. HSTAT provides access to a wide variety of publications, including clinical practice guidelines, quick-reference guides for clinicians, consumer health brochures, evidence reports and technology assessments from the Agency for Healthcare Research and Quality (AHRQ), as well as AHRQ’s Put Prevention Into Practice.27 Simply search by “Chiari malformation” (or synonyms) at the following Web site: http://text.nlm.nih.gov. Other users may find the Gateway useful for an overall search of NLM’s information resources. Some searchers may locate what they need immediately, while others will utilize the Gateway as an adjunct tool to other NLM search services such as PubMed® and MEDLINEplus®. The Gateway connects users with multiple NLM retrieval systems while also providing a search interface for its own collections. These collections include various types of information that do not logically belong in PubMed, LOCATORplus, or other established NLM retrieval systems (e.g., meeting announcements and pre-1966 journal citations). The Gateway will provide access to the information found in an increasing number of NLM retrieval systems in several phases. 25 Adapted from HSTAT: http://www.nlm.nih.gov/pubs/factsheets/hstat.html. 26 The HSTAT URL is http://hstat.nlm.nih.gov/. 27 Other important documents in HSTAT include: the National Institutes of Health (NIH) Consensus Conference Reports and Technology Assessment Reports; the HIV/AIDS 24


Coffee Break: Tutorials for Biologists28 Some parents may wish to have access to a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. To this end, we recommend “Coffee Break,” a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.29 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.30 This site has new articles every few weeks, so it can be considered an online magazine of sorts, and intended for general background information. You can access Coffee Break at http://www.ncbi.nlm.nih.gov/Coffeebreak/.

Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: ·

CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.

·

Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.

Treatment Information Service (ATIS) resource documents; the Substance Abuse and Mental Health Services Administration’s Center for Substance Abuse Treatment (SAMHSA/CSAT) Treatment Improvement Protocols (TIP) and Center for Substance Abuse Prevention (SAMHSA/CSAP) Prevention Enhancement Protocols System (PEPS); the Public Health Service (PHS) Preventive Services Task Force’s Guide to Clinical Preventive Services; the independent, nonfederal Task Force on Community Services Guide to Community Preventive Services; and the Health Technology Advisory Committee (HTAC) of the Minnesota Health Care Commission (MHCC) health technology evaluations. 28 Adapted from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html. 29 The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 30 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.


The Genome Project and Chiari Malformation With all the discussion in the press about the Human Genome Project, it is only natural that physicians, researchers, and parents want to know about how human genes relate to Chiari malformation. In the following section, we will discuss databases and references used by physicians and scientists who work in this area.

Online Mendelian Inheritance in Man (OMIM) The Online Mendelian Inheritance in Man (OMIM) database is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere. OMIM was developed for the World Wide Web by the National Center for Biotechnology Information (NCBI).31 The database contains textual information, pictures, and reference information. It also contains copious links to NCBI’s Entrez database of MEDLINE articles and sequence information. Go to http://www.ncbi.nlm.nih.gov/Omim/searchomim.html to search the database. Type “Chiari malformation” (or synonyms) in the search box, and click “Submit Search.” If too many results appear, you can narrow the search by adding the word “clinical.” Each report will have additional links to related research and databases. By following these links, especially the link titled “Database Links,” you will be exposed to numerous specialized databases that are largely used by the scientific community. These databases are overly technical and seldom used by the general public, but offer an abundance of information. The following is an example of the results you can obtain from the OMIM for Chiari malformation: ·

Jablonski’s Multiple Congenital Anomaly/Mental Retardation (MCA/MR) Syndromes Database32 This online resource can be quite useful. It has been developed to facilitate the identification and differentiation of syndromic entities. Special attention is given to the type of information that is usually limited or completely omitted in existing reference sources due to space limitations of the printed form. You can search across syndromes using an alphabetical index at http://www.nlm.nih.gov/mesh/jablonski/syndrome_toc/toc_a.html. At http://www.nlm.nih.gov/mesh/jablonski/syndrome_db.html, search by keyword. The Genome Database33 Established at Johns Hopkins University in Baltimore, Maryland in 1990, the Genome Database (GDB) is the official central repository for genomic mapping data resulting from the Human Genome Initiative. In the spring of 1999, the Bioinformatics Supercomputing Centre (BiSC) at the Hospital for Sick Children in Toronto, Ontario assumed the management of GDB. The Human Genome Initiative is a worldwide research effort focusing on structural analysis of human DNA to determine the location and sequence of the estimated 100,000 human genes. In support of this project, GDB stores and curates data generated by researchers worldwide who are engaged in the mapping effort of the Human Genome Project (HGP). GDB’s mission is to provide scientists with an encyclopedia of the human genome which is continually revised and updated to reflect the current state of scientific knowledge. Although GDB has historically focused on gene mapping, its focus will broaden as the Genome Project moves from mapping to sequence, and finally, to functional analysis. To access the GDB, simply go to the following hyperlink: http://www.gdb.org/.

APPENDIX A. RESEARCHING ALTERNATIVE MEDICINE Overview Complementary and alternative medicine (CAM) is one of the most contentious aspects of modern medical practice. You may have heard of these treatments on the radio or on television. Maybe you have seen articles written about these treatments in magazines, newspapers, or books. Perhaps your child’s doctor or your friends have mentioned alternatives. In this chapter, we will begin by giving you a broad perspective on complementary and alternative therapies. Next, we will introduce you to official information sources on CAM relating to Chiari malformation. Finally, at the conclusion of this chapter, we will provide a list of readings on Chiari malformation from various authors. We will begin, however, with the National Center for Complementary and Alternative Medicine’s (NCCAM) overview of complementary and alternative medicine.


What Is CAM?34 Complementary and alternative medicine (CAM) covers a broad range of healing philosophies, approaches, and therapies. Generally, it is defined as those treatments and healthcare practices which are not taught in medical schools, used in hospitals, or reimbursed by medical insurance companies. Many CAM therapies are termed “holistic,” which generally means that the healthcare practitioner considers the whole person, including physical, mental, emotional, and spiritual health. Some of these therapies are also known as “preventive,” which means that the practitioner educates and treats the person to prevent health problems from arising, rather than treating symptoms after problems have occurred. People use CAM treatments and therapies in a variety of ways. Therapies are used alone (often referred to as alternative), in combination with other alternative therapies, or in addition to conventional treatment (sometimes referred to as complementary). Complementary and alternative medicine, or “integrative medicine,” includes a broad range of healing philosophies, approaches, and therapies. Some approaches are consistent with physiological principles of Western medicine, while others constitute healing systems with non-Western origins. While some therapies are far outside the realm of accepted Western medical theory and practice, others are becoming established in mainstream medicine. Complementary and alternative therapies are used in an effort to prevent illness, reduce stress, prevent or reduce side effects and symptoms, or control or cure disease. Some commonly used methods of complementary or alternative therapy include mind/body control interventions such as visualization and relaxation, manual healing including acupressure and massage, homeopathy, vitamins or herbal products, and acupuncture.

What Are the Domains of Alternative Medicine?35 The list of CAM practices changes continually. The reason being is that these new practices and therapies are often proved to be safe and effective, and therefore become generally accepted as “mainstream” healthcare practices. Today, CAM practices may be grouped within five major domains: (1) alternative medical systems, (2) mind-body interventions, (3) biologicallybased treatments, (4) manipulative and body-based methods, and (5) energy 34 35

therapies. The individual systems and treatments comprising these categories are too numerous to list in this sourcebook. Thus, only limited examples are provided within each. Alternative Medical Systems Alternative medical systems involve complete systems of theory and practice that have evolved independent of, and often prior to, conventional biomedical approaches. Many are traditional systems of medicine that are practiced by individual cultures throughout the world, including a number of venerable Asian approaches. Traditional oriental medicine emphasizes the balance or disturbances of qi (pronounced chi) or vital energy in health and illness, respectively. Traditional oriental medicine consists of a group of techniques and methods including acupuncture, herbal medicine, oriental massage, and qi gong (a form of energy therapy). Acupuncture involves stimulating specific anatomic points in the body for therapeutic purposes, usually by puncturing the skin with a thin needle. Ayurveda is India’s traditional system of medicine. Ayurvedic medicine (meaning “science of life”) is a comprehensive system of medicine that places equal emphasis on body, mind, and spirit. Ayurveda strives to restore the innate harmony of the individual. Some of the primary Ayurvedic treatments include diet, exercise, meditation, herbs, massage, exposure to sunlight, and controlled breathing. Other traditional healing systems have been developed by the world’s indigenous populations. These populations include Native American, Aboriginal, African, Middle Eastern, Tibetan, and Central and South American cultures. Homeopathy and naturopathy are also examples of complete alternative medicine systems. Homeopathic medicine is an unconventional Western system that is based on the principle that “like cures like,” i.e., that the same substance that in large doses produces the symptoms of an illness, in very minute doses cures it. Homeopathic health practitioners believe that the more dilute the remedy, the greater its potency. Therefore, they use small doses of specially prepared plant extracts and minerals to stimulate the body’s defense mechanisms and healing processes in order to treat illness.


Naturopathic medicine is based on the theory that a medical condition is the manifestation of alterations in the processes by which the body naturally heals itself and emphasizes health restoration rather than treatment for the condition itself. Naturopathic physicians employ an array of healing practices, including the following: diet and clinical nutrition, homeopathy, acupuncture, herbal medicine, hydrotherapy (the use of water in a range of temperatures and methods of applications), spinal and soft-tissue manipulation, physical therapies (such as those involving electrical currents, ultrasound, and light), therapeutic counseling, and pharmacology.

Mind-Body Interventions Mind-body interventions employ a variety of techniques designed to facilitate the mind’s capacity to affect bodily function and symptoms. Only a select group of mind-body interventions having well-documented theoretical foundations are considered CAM. For example, patient education and cognitive-behavioral approaches are now considered “mainstream.” On the other hand, complementary and alternative medicine includes meditation, certain uses of hypnosis, dance, music, and art therapy, as well as prayer and mental healing. Biological-Based Therapies This category of CAM includes natural and biological-based practices, interventions, and products, many of which overlap with conventional medicine’s use of dietary supplements. This category includes herbal, special dietary, orthomolecular, and individual biological therapies. Herbal therapy employs an individual herb or a mixture of herbs for healing purposes. An herb is a plant or plant part that produces and contains chemical substances that act upon the body. Special diet therapies, such as those proposed by Drs. Atkins, Ornish, Pritikin, and Weil, are believed to prevent and/or control illness as well as promote health. Orthomolecular therapies aim to treat medical conditions with varying concentrations of chemicals such as magnesium, melatonin, and mega-doses of vitamins. Biological therapies include, for example, the use of laetrile and shark cartilage to treat cancer and the use of bee pollen to treat autoimmune and inflammatory conditions.


Manipulative and Body-Based Methods This category includes methods that are based on manipulation and/or movement of the body. For example, chiropractors focus on the relationship between structure and function, primarily pertaining to the spine, and how that relationship affects the preservation and restoration of health. Chiropractors use manipulative therapy as an integral treatment tool. In contrast, osteopaths place particular emphasis on the musculoskeletal system and practice osteopathic manipulation. Osteopaths believe that all of the body’s systems work together and that disturbances in one system may have an impact upon function elsewhere in the body. Massage therapists manipulate the soft tissues of the body to normalize those tissues. Energy Therapies Energy therapies focus on energy fields originating within the body (biofields) or those from other sources (electromagnetic fields). Biofield therapies are intended to affect energy fields (the existence of which is not yet experimentally proven) that surround and penetrate the human body. Some forms of energy therapy manipulate biofields by applying pressure and/or manipulating the body by placing the hands in or through these fields. Examples include Qi gong, Reiki and Therapeutic Touch. Qi gong is a component of traditional oriental medicine that combines movement, meditation, and regulation of breathing to enhance the flow of vital energy (qi) in the body, improve blood circulation, and enhance immune function. Reiki, the Japanese word representing Universal Life Energy, is based on the belief that, by channeling spiritual energy through the practitioner, the spirit is healed and, in turn, heals the physical body. Therapeutic Touch is derived from the ancient technique of “laying-on of hands.” It is based on the premises that the therapist’s healing force affects recovery and that healing is promoted when the body’s energies are in balance. By passing their hands over the patient, these healers identify energy imbalances. Bioelectromagnetic-based therapies involve the unconventional use of electromagnetic fields to treat illnesses or manage pain. These therapies are often used to treat asthma, cancer, and migraine headaches. Types of electromagnetic fields which are manipulated in these therapies include pulsed fields, magnetic fields, and alternating current or direct current fields.


Can Alternatives Affect My Child’s Treatment? A critical issue in pursuing complementary alternatives mentioned thus far is the risk that these might have undesirable interactions with your child’s medical treatment. It becomes all the more important to speak with the doctor who can offer advice on the use of alternatives. Official sources confirm this view. Though written for women, we find that the National Women’s Health Information Center’s advice on pursuing alternative medicine is appropriate for everyone.36 Is It Okay to Want Both Traditional and Alternative or Complementary Medicine? Should you wish to explore non-traditional types of treatment, be sure to discuss all issues concerning treatments and therapies with your child’s healthcare provider, whether a physician or practitioner of complementary and alternative medicine. Competent healthcare management requires that the practitioner know of all conventional and alternative therapies that your child is taking. The decision to use complementary and alternative treatments is an important one. Consider before selecting an alternative therapy, the safety and effectiveness of the therapy or treatment, the expertise and qualifications of the healthcare practitioner, and the quality of delivery. These topics should be considered when selecting any practitioner or therapy.

Finding CAM References on Chiari Malformation Having read the previous discussion, you may be wondering which complementary or alternative treatments might be appropriate for Chiari malformation. For the remainder of this chapter, we will direct you to a number of official sources which can assist you in researching studies and publications. Some of these articles are rather technical, so some patience may be required.

APPENDIX B. RESEARCHING NUTRITION Overview Since the time of Hippocrates, doctors have understood the importance of diet and nutrition to health and well-being. Since then, they have accumulated an impressive archive of studies and knowledge dedicated to this subject. Based on their experience, doctors and healthcare providers may recommend particular dietary supplements for Chiari malformation. Any dietary recommendation is based on age, body mass, gender, lifestyle, eating habits, food preferences, and health condition. It is therefore likely that different patients with Chiari malformation may be given different recommendations. Some recommendations may be directly related to Chiari malformation, while others may be more related to general health. In this chapter we will begin by briefly reviewing the essentials of diet and nutrition that will broadly frame more detailed discussions of Chiari malformation. We will then show you how to find studies dedicated specifically to nutrition and Chiari malformation.

Food and Nutrition: General Principles What Are Essential Foods? Food is generally viewed by official sources as consisting of six basic elements: (1) fluids, (2) carbohydrates, (3) protein, (4) fats, (5) vitamins, and (6) minerals. Consuming a combination of these elements is considered to be a healthy diet:


·

Fluids are essential to human life as 80-percent of the body is composed of water. Water is lost via urination, sweating, diarrhea, vomiting, diuretics (drugs that increase urination), caffeine, and physical exertion.

·

Carbohydrates are the main source for human energy (thermoregulation) and the bulk of typical diets. They are mostly classified as being either simple or complex. Simple carbohydrates include sugars which are often consumed in the form of cookies, candies, or cakes. Complex carbohydrates consist of starches and dietary fibers. Starches are consumed in the form of pastas, breads, potatoes, rice, and other foods. Soluble fibers can be eaten in the form of certain vegetables, fruits, oats, and legumes. Insoluble fibers include brown rice, whole grains, certain fruits, wheat bran and legumes.

·

Proteins are eaten to build and repair human tissues. Some foods that are high in protein are also high in fat and calories. Food sources for protein include nuts, meat, fish, cheese, and other dairy products.

·

Fats are consumed for both energy and the absorption of certain vitamins. There are many types of fats, with many general publications recommending the intake of unsaturated fats or those low in cholesterol.

Vitamins and minerals are fundamental to human health, growth, and, in some cases, disease prevention. Most are consumed in your child’s diet (exceptions being vitamins K and D which are produced by intestinal bacteria and sunlight on the skin, respectively). Each vitamin and mineral plays a different role in health. The following outlines essential vitamins: ·

Vitamin A is important to the health of eyes, hair, bones, and skin; sources of vitamin A include foods such as eggs, carrots, and cantaloupe.

·

Vitamin B1, also known as thiamine, is important for the nervous system and energy production; food sources for thiamine include meat, peas, fortified cereals, bread, and whole grains.

·

Vitamin B2, also known as riboflavin, is important for the nervous system and muscles, but is also involved in the release of proteins from nutrients; food sources for riboflavin include dairy products, leafy vegetables, meat, and eggs.

·

Vitamin B3, also known as niacin, is important for healthy skin and helps the body use energy; food sources for niacin include peas, peanuts, fish, and whole grains

·

Vitamin B6, also known as pyridoxine, is important for the regulation of cells in the nervous system and is vital for blood formation; food sources for pyridoxine include bananas, whole grains, meat, and fish.

Researching Nutrition 129

·

Vitamin B12 is vital for a healthy nervous system and for the growth of red blood cells in bone marrow; food sources for vitamin B12 include yeast, milk, fish, eggs, and meat.

·

Vitamin C allows the body’s immune system to fight various medical conditions, strengthens body tissue, and improves the body’s use of iron; food sources for vitamin C include a wide variety of fruits and vegetables.

·

Vitamin D helps the body absorb calcium which strengthens bones and teeth; food sources for vitamin D include oily fish and dairy products.

·

Vitamin E can help protect certain organs and tissues from various degenerative diseases; food sources for vitamin E include margarine, vegetables, eggs, and fish.

·

Vitamin K is essential for bone formation and blood clotting; common food sources for vitamin K include leafy green vegetables.

·

Folic Acid maintains healthy cells and blood; food sources for folic acid include nuts, fortified breads, leafy green vegetables, and whole grains.

It should be noted that it is possible to overdose on certain vitamins which become toxic if consumed in excess (e.g. vitamin A, D, E and K). Like vitamins, minerals are chemicals that are required by the body to remain in good health. Because the human body does not manufacture these chemicals internally, we obtain them from food and other dietary sources. The more important minerals include: ·

Calcium is needed for healthy bones, teeth, and muscles, but also helps the nervous system function; food sources for calcium include dry beans, peas, eggs, and dairy products.

·

Chromium is helpful in regulating sugar levels in blood; food sources for chromium include egg yolks, raw sugar, cheese, nuts, beets, whole grains, and meat.

·

Fluoride is used by the body to help prevent tooth decay and to reinforce bone strength; sources of fluoride include drinking water and certain brands of toothpaste.

·

Iodine helps regulate the body’s use of energy by synthesizing into the hormone thyroxine; food sources include leafy green vegetables, nuts, egg yolks, and red meat.

·

Iron helps maintain muscles and the formation of red blood cells and certain proteins; food sources for iron include meat, dairy products, eggs, and leafy green vegetables.


·

Magnesium is important for the production of DNA, as well as for healthy teeth, bones, muscles, and nerves; food sources for magnesium include dried fruit, dark green vegetables, nuts, and seafood.

·

Phosphorous is used by the body to work with calcium to form bones and teeth; food sources for phosphorous include eggs, meat, cereals, and dairy products.

·

Selenium primarily helps maintain normal heart and liver functions; food sources for selenium include wholegrain cereals, fish, meat, and dairy products.

·

Zinc helps wounds heal, the formation of sperm, and encourage rapid growth and energy; food sources include dried beans, shellfish, eggs, and nuts.

The United States government periodically publishes recommended diets and consumption levels of the various elements of food. Again, the doctor may encourage deviations from the average official recommendation based on your child’s specific condition. To learn more about basic dietary guidelines, visit the Web site: http://www.health.gov/dietaryguidelines/. Based on these guidelines, many foods are required to list the nutrition levels on the food’s packaging. Labeling Requirements are listed at the following site maintained by the Food and Drug Administration: http://www.cfsan.fda.gov/~dms/lab-cons.html. When interpreting these requirements, the government recommends that consumers become familiar with the following abbreviations before reading FDA literature:37 ·

DVs (Daily Values): A new dietary reference term that will appear on the food label. It is made up of two sets of references, DRVs and RDIs.

·

DRVs (Daily Reference Values): A set of dietary references that applies to fat, saturated fat, cholesterol, carbohydrate, protein, fiber, sodium, and potassium.

·

RDIs (Reference Daily Intakes): A set of dietary references based on the Recommended Dietary Allowances for essential vitamins and minerals and, in selected groups, protein. The name “RDI” replaces the term “U.S. RDA.”

·

RDAs (Recommended Dietary Allowances): A set of estimated nutrient allowances established by the National Academy of Sciences. It is updated periodically to reflect current scientific knowledge.

What Are Dietary Supplements?38 Dietary supplements are widely available through many commercial sources, including health food stores, grocery stores, pharmacies, and by mail. Dietary supplements are provided in many forms including tablets, capsules, powders, gel-tabs, extracts, and liquids. Historically in the United States, the most prevalent type of dietary supplement was a multivitamin/mineral tablet or capsule that was available in pharmacies, either by prescription or “over the counter.” Supplements containing strictly herbal preparations were less widely available. Currently in the United States, a wide array of supplement products are available, including vitamin, mineral, other nutrients, and botanical supplements as well as ingredients and extracts of animal and plant origin. The Office of Dietary Supplements (ODS) of the National Institutes of Health is the official agency of the United States which has the expressed goal of acquiring “new knowledge to help prevent, detect, diagnose, and treat disease and disability, from the rarest genetic disorder to the common cold.”39 According to the ODS, dietary supplements can have an important impact on the prevention and management of medical conditions and on the maintenance of health.40 The ODS notes that considerable research on the effects of dietary supplements has been conducted in Asia and Europe where the use of plant products, in particular, has a long tradition. However, the overwhelming majority of supplements have not been studied scientifically. To explore the role of dietary supplements in the improvement of health care, the ODS plans, organizes, and supports conferences, workshops, and symposia on scientific topics related to dietary supplements. The ODS often works in conjunction with other NIH Institutes and Centers, other government agencies, professional organizations, and public advocacy groups.

The Dietary Supplement Health and Education Act defines dietary supplements as “a product (other than tobacco) intended to supplement the diet that bears or contains one or more of the following dietary ingredients: a vitamin, mineral, amino acid, herb or other botanical; or a dietary substance for use to supplement the diet by increasing the total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of any ingredient described above; and intended for ingestion in the form of a capsule, powder, softgel, or gelcap, and not represented as a conventional food or as a sole item of a meal or the diet.” 38

Finding Studies on Chiari Malformation The NIH maintains an office dedicated to nutrition and diet. The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.41 IBIDS is available to the public free of charge through the ODS Internet page: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. We recommend that you start with the Consumer Database. While you may not find references for the topics that are of most interest to you, check back periodically as this database is frequently updated. More studies can be found by searching the Full IBIDS Database. Healthcare professionals and researchers generally use the third option, which lists peer-reviewed citations. In all cases, we suggest that you take advantage of the “Advanced Search” option that allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “Chiari malformation” (or synonyms) into the search box. To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

APPENDIX C. FINDING MEDICAL LIBRARIES Overview At a medical library you can find medical texts and reference books, consumer health publications, specialty newspapers and magazines, as well as medical journals. In this Appendix, we show you how to quickly find a medical library in your area.

Preparation Before going to the library, highlight the references mentioned in this sourcebook that you find interesting. Focus on those items that are not available via the Internet, and ask the reference librarian for help with your search. He or she may know of additional resources that could be helpful to you. Most importantly, your local public library and medical libraries have Interlibrary Loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. NLM’s interlibrary loan services are only available to libraries. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.42

APPENDIX D. YOUR CHILD’S RIGHTS AND INSURANCE Overview Parents face a series of issues related more to the healthcare industry than to their children’s medical conditions. This appendix covers two important topics in this regard: your responsibilities and your child’s rights as a patient, and how to get the most out of your child’s medical insurance plan.

Your Child’s Rights as a Patient The President’s Advisory Commission on Consumer Protection and Quality in the Healthcare Industry has created the following summary of your child’s rights as a patient.44 Information Disclosure Consumers have the right to receive accurate, easily understood information. Some consumers require assistance in making informed decisions about health plans, health professionals, and healthcare facilities. Such information includes: ·

Health plans. Covered benefits, cost-sharing, and procedures for resolving complaints, licensure, certification, and accreditation status, comparable measures of quality and consumer satisfaction, provider network composition, the procedures that govern access to specialists and emergency services, and care management information.

44Adapted

from Consumer Bill of Rights and Responsibilities: http://www.hcqualitycommission.gov/press/cbor.html#head1.


·

Health professionals. Education, board certification, and recertification, years of practice, experience performing certain procedures, and comparable measures of quality and consumer satisfaction.

·

Healthcare facilities. Experience in performing certain procedures and services, accreditation status, comparable measures of quality, worker, and consumer satisfaction, and procedures for resolving complaints.

·

Consumer assistance programs. Programs must be carefully structured to promote consumer confidence and to work cooperatively with health plans, providers, payers, and regulators. Desirable characteristics of such programs are sponsorship that ensures accountability to the interests of consumers and stable, adequate funding.

Choice of Providers and Plans Consumers have the right to a choice of healthcare providers that is sufficient to ensure access to appropriate high-quality healthcare. To ensure such choice, the Commission recommends the following: ·

Provider network adequacy. All health plan networks should provide access to sufficient numbers and types of providers to assure that all covered services will be accessible without unreasonable delay -including access to emergency services 24 hours a day and 7 days a week. If a health plan has an insufficient number or type of providers to provide a covered benefit with the appropriate degree of specialization, the plan should ensure that the consumer obtains the benefit outside the network at no greater cost than if the benefit were obtained from participating providers.

·

Access to specialists. Consumers with complex or serious medical conditions who require frequent specialty care should have direct access to a qualified specialist of their choice within a plan’s network of providers. Authorizations, when required, should be for an adequate number of direct access visits under an approved treatment plan.

·

Transitional care. Consumers who are undergoing a course of treatment for a chronic or disabling condition at the time they involuntarily change health plans or at a time when a provider is terminated by a plan for other than cause should be able to continue seeing their current specialty providers for up to 90 days to allow for transition of care.

·

Choice of health plans. Public and private group purchasers should, wherever feasible, offer consumers a choice of high-quality health insurance plans.

Your Child’s Rights and Insurance 147

Access to Emergency Services Consumers have the right to access emergency healthcare services when and where the need arises. Health plans should provide payment when a consumer presents to an emergency department with acute symptoms of sufficient severity--including severe pain--such that a “prudent layperson” could reasonably expect the absence of medical attention to result in placing that consumer’s health in serious jeopardy, serious impairment to bodily functions, or serious dysfunction of any bodily organ or part.

Participation in Treatment Decisions Consumers have the right and responsibility to fully participate in all decisions related to their healthcare. Consumers who are unable to fully participate in treatment decisions have the right to be represented by parents, guardians, family members, or other conservators. Physicians and other health professionals should: ·

Provide parents with sufficient information and opportunity to decide among treatment options consistent with the informed consent process.

·

Discuss all treatment options with a parent in a culturally competent manner, including the option of no treatment at all.

·

Ensure that persons with disabilities have effective communications with members of the health system in making such decisions.

·

Discuss all current treatments a consumer may be undergoing.

·

Discuss all risks, nontreatment.

·

Give parents the opportunity to refuse treatment for their children and to express preferences about future treatment decisions.

·

Discuss the use of advance directives -- both living wills and durable powers of attorney for healthcare -- with parents.

·

Abide by the decisions made by parents consistent with the informed consent process.

or


Health plans, health providers, and healthcare facilities should: ·

Disclose to consumers factors -- such as methods of compensation, ownership of or interest in healthcare facilities, or matters of conscience -that could influence advice or treatment decisions.

·

Assure that provider contracts do not contain any so-called “gag clauses” or other contractual mechanisms that restrict healthcare providers’ ability to communicate with and advise parents about medically necessary treatment options for their children.

·

Be prohibited from penalizing or seeking retribution against healthcare professionals or other health workers for advocating on behalf of their patients. Respect and Nondiscrimination

Consumers have the right to considerate, respectful care from all members of the healthcare industry at all times and under all circumstances. An environment of mutual respect is essential to maintain a quality healthcare system. To assure that right, the Commission recommends the following: ·

Consumers must not be discriminated against in the delivery of healthcare services consistent with the benefits covered in their policy, or as required by law, based on race, ethnicity, national origin, religion, sex, age, mental or physical disability, sexual orientation, genetic information, or source of payment.

·

Consumers eligible for coverage under the terms and conditions of a health plan or program, or as required by law, must not be discriminated against in marketing and enrollment practices based on race, ethnicity, national origin, religion, sex, age, mental or physical disability, sexual orientation, genetic information, or source of payment.

Confidentiality of Health Information Consumers have the right to communicate with healthcare providers in confidence and to have the confidentiality of their individually identifiable healthcare information protected. Consumers also have the right to review and copy their own medical records and request amendments to their records.


Complaints and Appeals Consumers have the right to a fair and efficient process for resolving differences with their health plans, healthcare providers, and the institutions that serve them, including a rigorous system of internal review and an independent system of external review. A free copy of the Patient’s Bill of Rights is available from the American Hospital Association.45

Parent Responsibilities To underscore the importance of finance in modern healthcare as well as your responsibility for the financial aspects of your child’s care, the President’s Advisory Commission on Consumer Protection and Quality in the Healthcare Industry has proposed that parents understand the following “Consumer Responsibilities.”46 In a healthcare system that protects consumers’ rights, it is reasonable to expect and encourage consumers to assume certain responsibilities. Greater involvement by parents in their children’s care increases the likelihood of achieving the best outcome and helps support a quality-oriented, cost-conscious environment. Such responsibilities include: ·

Take responsibility for maximizing your child’s healthy habits.

·

Work collaboratively with healthcare providers in developing and carrying out your child’s agreed-upon treatment plans.

·

Disclose relevant information and clearly communicate wants and needs.

·

Use the insurance company’s internal complaint and appeal processes to address your concerns.

·

Recognize the reality of risks, the limits of the medical science, and the human fallibility of the healthcare professional.

·

Be aware of a healthcare provider’s obligation to be reasonably efficient and equitable in providing care to the community.

·

Choosing an Insurance Plan There are a number of official government agencies that help consumers understand their healthcare insurance choices.47 The U.S. Department of Labor, in particular, recommends ten ways to make your health benefits choices work best for your family.48 1. Your options are important. There are many different types of health benefit plans. Find out which one your employer offers, then check out the plan, or plans, offered. Your employer’s human resource office, the health plan administrator, or your union can provide information to help you match your family’s needs and preferences with the available plans. The more information you have, the better your healthcare decisions will be. 2. Reviewing the benefits available. Do the plans offered cover preventive care, well-baby care, vision or dental care? Are there deductibles? Answers to these questions can help determine the out-of-pocket expenses you may face. Cheapest may not always be best. Your goal is high quality health benefits. 3. Look for quality. The quality of healthcare services varies, but quality can be measured. You should consider the quality of healthcare in deciding among the healthcare plans or options available to your family. Not all health plans, doctors, hospitals and other providers give the highest quality care. Fortunately, there is quality information you can use right now to help you compare your healthcare choices. Find out how you can measure quality. Consult the U.S. Department of Health and Human Services publication “Your Guide to Choosing Quality Health Care” on the Internet at www.ahcpr.gov/consumer.

More information about quality across programs is provided at the following AHRQ Web site: http://www.ahrq.gov/consumer/qntascii/qnthplan.htm. 48 Adapted from the Department of Labor: http://www.dol.gov/dol/pwba/public/pubs/health/top10-text.html. 47


4. Your plan’s summary plan description (SPD) provides a wealth of information. Your health plan administrator can provide you with a copy of your plan’s SPD. It outlines your family’s benefits and your legal rights under the Employee Retirement Income Security Act (ERISA), the federal law that protects your family’s health benefits. It should contain information about the coverage of dependents, what services will require a co-pay, and the circumstances under which your employer can change or terminate a health benefits plan. Save the SPD and all other health plan brochures and documents, along with memos or correspondence from your employer relating to health benefits. 5. Assess your benefit coverage as your family status changes. Marriage, divorce, childbirth or adoption, and the death of a spouse are all life events that may signal a need to change your health benefits. You, your spouse and dependent children may be eligible for a special enrollment period under provisions of the Health Insurance Portability and Accountability Act (HIPAA). Even without life-changing events, the information provided by your employer should tell you how you can change benefits or switch plans, if more than one plan is offered. If your spouse’s employer also offers a health benefits package, consider coordinating both plans for maximum coverage. 6. Changing jobs and other life events can affect your family’s health benefits. Under the Consolidated Omnibus Budget Reconciliation Act (COBRA), you, your covered spouse, and your dependent children may be eligible to purchase extended health coverage under your employer’s plan if you lose your job, change employers, get divorced, or upon occurrence of certain other events. Coverage can range from 18 to 36 months depending on your situation. COBRA applies to most employers with 20 or more workers and requires your plan to notify you of your rights. Most plans require eligible individuals to make their COBRA election within 60 days of the plan’s notice. Be sure to follow up with your plan sponsor if you don’t receive notice, and make sure you respond within the allotted time. 7. HIPAA can also help if you are changing jobs, particularly if you have a medical condition. HIPAA generally limits pre-existing condition exclusions to a maximum of 12 months (18 months for late enrollees). HIPAA also requires this maximum period to be reduced by the length of time you had prior “creditable coverage.” You should receive a certificate documenting your prior creditable coverage from your old plan when coverage ends. 8. Plan for retirement. Before you retire, find out what health benefits, if any, extend to you and your spouse during your retirement years. Consult with


your employer’s human resources office, your union, the plan administrator, and check your SPD. Make sure there is no conflicting information among these sources about the benefits your family will receive or the circumstances under which they can change or be eliminated. With this information in hand, you can make other important choices, like finding out if you are eligible for Medicare and Medigap insurance coverage. 9. Know how to file an appeal if a health benefits claim is denied. Understand how your plan handles grievances and where to make appeals of the plan’s decisions. Keep records and copies of correspondence. Check your health benefits package and your SPD to determine who is responsible for handling problems with benefit claims. Contact PWBA for customer service assistance if you are unable to obtain a response to your complaint. 10. You can take steps to improve the quality of the healthcare and the health benefits your family receives. Look for and use things like Quality Reports and Accreditation Reports whenever you can. Quality reports may contain consumer ratings -- how satisfied consumers are with the doctors in their plan, for instance-- and clinical performance measures -- how well a healthcare organization prevents and treats illness. Accreditation reports provide information on how accredited organizations meet national standards, and often include clinical performance measures. Look for these quality measures whenever possible. Consult “Your Guide to Choosing Quality Health Care” on the Internet at www.ahcpr.gov/consumer.

Medicaid Illness strikes both rich and poor families. For low-income families, Medicaid is available to defer the costs of treatment. In the following pages, you will learn the basics about Medicaid as well as useful contact information on how to find more in-depth information. Medicaid is a joint federal and state program that helps pay medical costs for some people with low incomes and limited resources. Medicaid programs vary from state to state. You can find more information about Medicaid on the HCFA.gov Web site at http://www.hcfa.gov/medicaid/medicaid.htm.

NORD’s Medication Assistance Programs Finally, the National Organization for Rare Disorders, Inc. (NORD) administers medication programs sponsored by humanitarian-minded


pharmaceutical and biotechnology companies to help uninsured or underinsured individuals secure life-saving or life-sustaining drugs.49 NORD programs ensure that certain vital drugs are available “to those families whose income is too high to qualify for Medicaid but too low to pay for their prescribed medications.” The program has standards for fairness, equity, and unbiased eligibility. It currently covers some 14 programs for nine pharmaceutical companies. NORD also offers early access programs for investigational new drugs (IND) under the approved “Treatment INDs” programs of the Food and Drug Administration (FDA). In these programs, a limited number of individuals can receive investigational drugs that have yet to be approved by the FDA. These programs are generally designed for rare medical conditions.
