Presentation on theme: "Ehlers-Danlos Syndrome/ Joint Hypermobility Syndrome"— Presentation transcript:
1Ehlers-Danlos Syndrome/ Joint Hypermobility Syndrome For purposes of this discussion:EDS III and JHS are regarded as the same disorder.Hypermobility is a feature of most forms of EDS.EDS/JHS patients fall along a spectrum of hypermobility.Are We Really Zebras,or Just Horses of Different Colors?Heidi Collins, MD
2ZebraMost medical professionals think EDS/JHS is exceedingly rare and exotic – a “Zebra”.EDS/JHS is something most medical professionals do not expect to encounter.“I’ve heard of it. Never seen it before. We learned about it in medical school.” (said by a neurosurgeon to one of my patients with EDS/JHS)“It must be something else. I’ve been in practice 19 years, and I’ve seen everything. I’ve never seen a kid with that.” (said by a pediatric hospitalist to me, regarding POTS in my child with EDS/JHS)
3Horse of a Different Color “A horse of a different color metaphorically represents something that may be completely separate from what one originally expected. Frequently, a horse of a different color may be a complete surprise, an unexpected truth or a feature that seems somehow out of place.” (from “Idioms Unpacked”)
4Thought it was a fibroymyalgia horse, IBS/gut dysmotility horse, orthostatic intolerance horse, migraine horse, etc…
6How Rare is JHS?“Reports of the prevalence of [JHS] must be viewed cautiously because of the variability in the diagnostic criteria used. Hypermobility syndrome has been reported in 0.6% to 31.5% of adults without joint pain, depending on age, ethnicity, and criteria for assessing hypermobility.” (Russek LN. Hypermobility syndrome. Phys Ther. 1999;79:591–599.)
7Prevalence: General Population (Russek LN. Hypermobility syndrome Prevalence: General Population (Russek LN. Hypermobility syndrome. Phys Ther. 1999;79:591–599.)The prevalence of Hypermobility Syndrome quoted on the previous slide is the range among the studies in which Beighton Criteria is used.The range among all studies included here is 0.6% to 39.6%.
8Prevalence: Joint or Muscle Pain (Russek LN. Hypermobility syndrome Prevalence: Joint or Muscle Pain (Russek LN. Hypermobility syndrome. Phys Ther. 1999;79:591–599.)Prevalence ranges from 0.0 to 81.0%!
9Why do I care about this topic? I am an EDS/JHS patient.I am a medical professional.I believe both patients and medical professionals need to understand EDS/JHS as something that may be unexpected but is not so rare and exotic!I believe EDS/JHS patients and medical professionals need to have reasonable expectations of one another.Aspects of EDS/JHS of particular personal interest to me:Extraarticular Manifestations and Secondary SyndromesOrthostatic Intolerance: POTSTracheobronchomalacia/Tracheobronchomegaly:Upper Airway Resistance SyndromeMounier-Kuhn SyndromeWilliams-Cambell SyndromeInsomniaAortic Root DilatationComplications/Risks of Pregnancy
10Our Responsibilities As EDS/JHS Patients Use every resource available to educate ourselves about EDS/JHS.Learn how to prioritize treatment goals.Learn to advocate effectively for the best medical care.Educate others (medical professionals, family members, friends, schools, employers, etc.) regarding EDS/JHS.
11Our Responsibilities As Medical Professionals Diagnose: Recognize EDS/JHS and differentiate it from other “less rare and exotic” conditions.Treat: Address the difficulties experienced by EDS/JHS patients.Research: An Ongoing ProcessStrive to understand EDS/JHS and related disorders.Continually refine and update the standard of care for patients with EDS/JHS and associated connective tissue disorders.Identify specific opportunities for impact in individual specialties.Identify areas deserving further research.Continue to integrate emerging knowledge into everyday practice. (Continuing Medical Education)For example: Scoliosis Screening – Why not Hypermobility Screening?For example: ASD – Used to be a specialty diagnosis. PCPs did not think of it!
12Why is it so hard?Especially, why is it so hard for an EDS/JHS patient to get diagnosed?It has to do with how medical professionals are trained to diagnose.
13The Zebra Aphorism: History "When you hear hoofbeats, think horses, not zebras." (Theodore E. Woodward, MD, University of Maryland, circa 1950)Earlier Versions:“When you hear hoofbeats behind you, don't expect to see a zebra.”“Don't look for zebras on Greene Street.”Aphorism:A brief statement of a principle.An adage.A truth or an opinion.
14The Zebra Aphorism: Addresses Misconceptions about Probabilities “The striking and novel stay longer in the mind.” (Rhetorica ad Herennium, 85 BC)“Events more easily remembered are judged more probable.” (The Availability Heuristic)So that rare disorders are not overdiagnosed, it is important to resist the tendency to assign rare diagnoses; instead, remember to consider most probable causes or conditions first.
15The Zebra Aphorism: For Novices Only Meant for medical novices, not experienced medical professionals!Medical Student Syndrome (seeNot limited to medical students.Anyone who reads medical literature is susceptible!Medical Students’ Disease (see Wikipedia)When overused among fully trained professionals, the Zebra Aphorism leads to unwarranted skepticism regarding acceptance of rare diagnoses when they actually occur.
16Ockham’s Razor: Keeping it Simple Sometimes stated as: “The simplest explanation is usually the best.” (William of Ockham, fourteenth century English logician and Franciscan friar)Stresses keeping theories as simple as possible, with as few assumptions as possible."Entities should not be multiplied beyond necessity.” (Latin, as “lex parsimoniae”)“Simplicity is the ultimate sophistication.” (Leonardo da Vinci)“Theories should be as simple as possible, but no simpler.” (Albert Einstein)“Keep It Simple, Stupid!” (The KISS Principle)In modern medicine, this is known as “Diagnostic Parsimony”: Strive to look for the fewest possible diagnoses (ideally a singular diagnosis) to explain symptoms and findings.
17Hickam’s Dictum: Adds Balance to Ockham’s Razor “Patients can have as many diseases as they damn well please.” (John Hickam, MD., Duke University, circa 1950)Often, it is statistically more likely that a patient has several common diseases rather than a single rare disease.Furthermore, even when statistically unlikely, patients can prove to have multiple diseases.
18Bottom Line: Diagnosticians Must Recognize Diseases When Present “In making the diagnosis of the cause of illness in an individual case, calculations of probability have no meaning. The pertinent question is whether the disease is present or not. Whether it is rare or common does not change the odds in a single patient. ...If the diagnosis can be made on the basis of specific criteria, then these criteria are either fulfilled or not fulfilled.” (A. McGhee Harvey, James Bordley II, Jeremiah Barondness)This is a critical principle physicians need to remember!!!
19The EDS/JHS diagnostic experience can be crushing! Ever feel like you’ve been told:“You’re a horse. Shut up and eat your hay!”Ever been accused of doctor shopping?Ever been accused of having an agenda?Variations on a theme:“But you don’t look sick.”“Are you faking/crazy?”How many costly or painful tests came back “negative” or “normal”?How long is your list of diagnoses?
20The Journey to Diagnosis How Much Time: Weeks? Months? Years?Lengthy Referral ProcessesLong Waits for AppointmentsHow Much Money?Medical ExpensesTravel ExpensesTreatments Not Covered by InsuranceLost Income, etc.How Many Stops/Detours/Dead Ends?How useful was each medical professional?How many along the way? 10? 20? More?
21The Journey to Diagnosis: Valid Questions from Patients Should physicians be expected to recognize every rare or uncommon disease “in the book”?How much does a typical medical professional know or recall about connective tissue disorders?
22The Journey to Diagnosis: Valid Answers from Professionals I don’t know.I will look it up.I will find someone else who does know.Also, “Yes – I will read that article!”

25http://somedaywewillsleep.com/ From “About” …I live in Tasmania with my partner, Nathan and our two children, Amy – born September ’06 and Isaac, born January ’09. They keep me busy and remind me to smile at the small things and laugh at the big things. Amy is currently undergoing diagnosis for Aspergers and has been diagnosed with Ehlers Danlos Syndrome. Isaac also has Ehlers Danlos, and is currently being assessed for Autism.I started blogging in 2007, when Amy was almost 12 months old and not sleeping. Ever. Hence the title. Since then she has learned to sleep through the night, but I have not. A chronic insomniac, I spend all hours of the night awake and wishing I wasn’t.…In April 09, I was diagnosed with Ehlers Danlos Syndrome after years of worsening symptoms. Having EDS is not fun, but having a diagnosis now makes life a little easier. Most of my joints either sublux (partially dislocate) or dislocate fully at some stage. This is about as painful as you would imagine it to be. I swear, a lot.In addition to providing accessibility to information, the Web serves to provide social connection and support for patients who are struggling with EDS/JHS as it impacts their daily life.Medical professionals need to understand that a powerful patient network exists!EDS/JHS has a human face, and patients have a life beyond the minutes they spend in clinic contact!In particular, doctors who are barely familiar with EDS/JHS may begin to understand how articular (joint) manifestations can be disabling, but they often do not understand the significance of how insomnia or POTS or other extra-articular (non-joint) manifestations can be so disabling.
26Strength in Numbers: Horton Hears a Who! A voice previously unheard gains strength in numbers.Whether EDS/JHS is “rare” or “uncommon”, numbers like 1 in 5,000 or >1 in 100 matter little now.Modern technology has allowed patients to find one another and be heard.
28Smackdown!When they are correct in self-diagnosis, patients all too often are dismissed by medical professionals.“No, you can’t have that. It’s just too rare.”“Well, I suppose it’s possible, but I don’t know anything about that, so let’s stick to something I DO know.”Don’t go down for the count!!!
29The Journey is Not OverEven when an EDS/JHS “zebra” is finally recognized, whether diagnosed by a knowledgeable medical professional or through self-diagnosis and self-advocacy, the journey is not over.
30Baggage: Re-Packing for the Next Part of the Journey
31Baggage: Re-Packing for the Next Part of the Journey Once diagnosed, in order to set priorities for treatment goals, medical professionals must help patients with their “baggage”.The List of Diagnoses EDS/JHS Patients CarryIs each diagnosis primary or secondary?Better control of primary problems can lessen secondary problems.What are the overlapping diagnoses?Realize when successful treatment of one problem may not alleviate symptoms altogether.Can any diagnoses be struck from the list?Fibromyalgia, Chronic Fatigue, Irritable Bowel Syndrome, Paroxysmal Atrial Tahcycardia, Depression, Anxiety, etc.Especially true for “Diagnosis of Exclusion”.LESS IS MORE!!!Can some bags be put into storage?Are some bags carry-on and others checked through?
32The Next Part of the Journey: Treatment It is reasonable for a patient to expect that a medical professional can provide or arrange treatment for EDS/JHS.For some EDS/JHS patients:This expectation is not met.This expectation is met, but with great difficulty.Treatment of EDS/JHS may be challenging, but it should not be considered impossible!
33A Huge UnderstatementAt present, EDS/JHS is not well-known by the average medical professional.
34Why is EDS/JHS not well-known by the average medical professional? For some, it was long ago forgotten.They skipped that chapter in medical school.They got enough of the other questions right to pass.The Zebra Aphorism gets overused.No single diagnostic test is available.Laboratory: Blood, Urine, Biopsy, Fibroblast Culture, etc.Imaging: X-ray, MRI, Ultrasound, etc.Established scores and criteria help, however…Lack of AwarenessPotential Difficulties with Interobserver ReliabilityNo definitive pharmacological or surgical treatment exists.Why look for it if I can’t do anything about it?

37Growing Body of Knowledge A considerable body of knowledge regarding the diagnosis and treatment of EDS/JHS does exist.When this knowledge is put into practice, patients can gain/regain significant health and functionality.The body of knowledge has grown, especially in recent years, and will continue to grow.This underscores the importance of organizations like EDNF.Resources are readily available on the EDNF Web Site.Medical LiteratureContact Information for Other Medical ProfessionalsNewslettersNo Excuses!Medical professionals must make a reasonable effort to gain the knowledge they need to benefit their patients!
38Medical Professionals: When to Use the Web When modern practitioners feel limited by their own knowledge or their local resources, they need to learn to navigate the Web as an easily accessible means of continuing their own medical education and connecting patients with capable or experienced medical professionals, official organizations, educational resources, and other means of support!!!
39The Web: Words of Caution The Web DOES NOT eliminate the need for face-to-face patient-physician interaction.Information from the Web should be discussed between patients and medical professionals.Patients need help recognizing whether information is from a valid, credible source.Medical professionals must not disregard information solely because a patient found it while surfing the Web.Medical professionals must verify the credibility of information before integrating it into practice.The Web is a magnificent tool for self-education for both patients and practitioners, ***HOWEVER*** it has its pros and cons, and information from the web needs to be utilized in an APPROPRIATE fashion.Example: From EDNF Vision and MissionRegarding Accuracy of Information“The Professional Advisory Network reviews all information published on the website (excluding news). The Medical Professionals area contains the most detailed and comprehensive information available online about EDS. New articles are published as soon as they are approved.”
42The Web: Words of Caution When surfing the Web, there is no lifeguard on duty.Regarding Web-based information, ask yourself:Fact?Fiction?MisinformationUrban MythsSpeculation?Strive to be able to tell the difference between fact, fiction, speculation, etc.
43In Conclusion EDS/JHS is NOT exceedingly rare. As a person with EDS/JHS, I do not think of myself as a zebra!I am just a horse of a different color.Now, if I could just get more than a handful of my fellow medical professionals to tell the difference between zebras and horses...
