Dystonia in the Joint Hypermobility Syndrome

Dystonia in the Joint Hypermobility SyndromeEhlers-Danlos syndrome first described by Tschernogobow (1896) in capital of the Russian Federation and Ehlers (1900) in Copenh mount upn is a nearly autosomal inherited genetic unhealthiness of collagen synthesis that sensitizes the ensemble of the connection tissue which becomes slight resistant and less elastic. These ii characteristics explain the symptomatology fragility of the skin, of the vessels (haemorrhages) and the presence of a subdued proprioceptive syndrome due to dysfunction of the receptors which be implanted into little or non-reactive connective tissue. Diagnosis of the hypermobile type of explosive detection system is solely clinical as in that location is to date no genetic maker for the most ghost counterfeit of explosive detection system. The rarity of the disease needs to be put into question sooner the crowd of uncomplainings at consultations. Our experience is based on an active database of 2212 toler ants which in all fall under the Villefranche criteria. A great number of signs and symptoms have unless to be attributed to this syndrome. They be, combined with the unawareness of physicians nearly the syndrome, at the origin of healthful errors accompanied by the iatrogenic effects of prejudice towards these patients. This is the case of dystonia which is wassail in 75% of our cases. Dystonia plays an important part in the functional tenderness which is at the origin of a number of handicap situations. It seems to be related to dysautonomia common amongst the patients, proprioceptive problems and the multiple pains caused by the syndrome. Dystonia get byment with Amantadine and levodopa permits to obtain results which go advertise than the normally associated extra-pyramidal treatment and opens new perspectives on the management of a syndrome that has been particularly difficult to treat.Key-Words Ehlers-Danlos syndrome (EDS), dystonia, dysautonomia, L-dopa, pains, ha rass.Dystonia in the joint hypermobility syndrome (a.k.a. Ehlers-Danlos syndrome, hypermobility type). mental hospitalEhlers-Danlos syndrome (EDS) recognition went through many an(prenominal) vicissitudes since the first outstanding description by Tschernogobow (1) and Ehlers (2) respectively in Moscow in 1896 and in Copenhagen in 1900. EDS genetic grounds have been recognized since 1949 (4) collagens role as untimely as 1956 (5). EDS was studied in parallel by the rheumatologists (Brighton and Grahame) and the geneticist (Beighton) who are each working mainly on articular hypermobility with different sagacity tests. There is perfect similarity in the midst of the rheumatologists joint hypermobility syndrome and the geneticists EDS hypermobility type. These two denominations refer in fact to the same illness. However, a great system of clinical manifestations has non yet been assigned to this syndrome. They are, in combination with the physicians inveterate unawareness of thi s syndrome, the cause of many symptomatic wavering with their iatrogenic side-effects that wrong the patients. This is the case with dystonia.MATERIAL AND METHODS2,212 patients were diagnosed and followed up in the Ehlers-Danlos consultation in Paris, in the midst of 2006 and 2015. They were all examined by the same physician with the same evaluation power system both qualitative and quantitative allowing to rate from 0 to 4 the symptoms natural severity and objective data from clinical examination. The populations age varies from 2 days to 69 years (mean age 32). 80% are women.Inclusion criteriaAll the patients in this con met the criteria of the geneticians Villefranche classification (6).On top of the criteria inwardly this classification, we observed a collection of 153 patients examined in 2013 with a quotation of severity equal or lord to 2/4 (medium intensity) with clinical manifestations of the future(a) multiple pains (95%), fatigue (93%), proprioceptive problems (92%), hemorrhages (93%), GERD (72%), bucco-dental manifestations (72%), hyperacousia (75%), diplopia (74%), SOB (76%), dysautonomia heavy sweating (70%), c old credulity (74%), a pseudo Raynaud with cold extremities (84%), cognitive problems attention (79%) and memory (72%). As of date in that respect is no genetic test available for the hypermobile cook of EDS. Finding other cases amongst the patients family (95%) is a strong diagnostic argument.Dystonia identificationDystonia was diagnosed if a patient suffered from one or several of the following symptomsInvoluntary muscular contr put to deaths without movement such as fasciculation on the face, blepharospasm mainly, on the thigh, reminding of a mobile phone vibration in a gasp pocket,Sudden movements such as a fit of the wrist, the shoulders, the legs or wide-eyed movements which results in hitting objects or people or throwing off rest period the patient for whom they occur in the lower limbs affright, jerking, hesitant hand movementsTrembling fingers or thumbs in motion or at rest healthy contractions often described as hardening of muscles, rigidity, constraining movement, or as crampsLasting contractions in forced flexion of the thumb or fingers, in flexion and adduction of the feet,Writers cramp when writing after unsettled amounts of time,Incessant, repetitive movement in flexion or extension of the hindquarters and knee when sitting with feet on the ground,Repetitive movement of the trunk alternate between flexion and extension at the hipDiffuse unfermented crises at the lower limbs with alternating, dotty movements worsened by tenting to parry themShort contractions of the lower limbs leading to a fallPartial or generalized tonic-clonic movements and the possibility of hematomas facilitated by the fine skin and the fragility of the vessels. These elicit be confused with seizure activity but the EEG corpse normalRestless leg syndrome at night, which sometimes evolves into rattling vi olent jerksBruxism, which we often encounter in EDS patients could be related to dystoniaThese dystonic contractions inflame luxations of the shoulder, fingers, a hip, knee or the maxilla. They are most commonly of sententious duration but fag end prolong over several days, weeks, months or exceptionally years as we have observed in a few cases.Dystonia is associated with the accentuation of other manifestations of the syndrome. Pain often ontogenys to a very intense level in the part of the body where the dystonia occurs. Dysautonomic problems (vasomotor, sweating, tachycardia, orthostatic hypotension, halt and cold intolerance, nausea, fighters of generally feeling unwell, POTS) at which Jaime Bravo (7) attaches fatigue. Pain itself can also provoke dystonia sometimes due to sub stingeraneous or intramuscular injections, traumatism, or simply during physical exam manoeuvre. It is perceived as excruciating by these hyperalgesic patients.Dystonia exists in 75% of our patients with the following severity index 2/4 (39%), 3/4 (29%) and 4/4 (7%).The treatment of dystonia within EDSOur therapeutic approach of EDS (8) centres on the amelioration of the proprioceptive troubles, of the pain as well as the fatigue. Foremost we use proprioceptive shoe inlays and particularly proprioceptive clothing specifically adapted for EDS, derived from the treatment of burn victims and oxygen therapy against fatigue, shortness of breath and migraines. For the last five years we have successfully used Amantadine after the discussion with Pierre Cesaro (neurologist, specialiser in the treatment of Parkinson). (9)When it was taken of the market in France we sought to deputise it with L-Dopa which we prescribe at a low dosage (62,5 mg q3d Modopar 50mg L-Dopa +12,5mg Benserazide hydrochloride) adjusted to the needs of the patient oddly in dreaded cases.We describe here the case of a 54 year old woman, a family medicine physician, who had been diagnosed with EDS-HT. Signs pr esent since childhood worsened at the age of 52 muscular pain, intense fatigue, proprioceptive problems manifesting most importantly with difficulties waling. Signs of dystonia could be observed in the lower limbs. She is very tired with crises of somnolence that confuse her victor life. The fatigue and muscular pain is partially take overd by wearing proprioceptive shoe inlays, 3 sessions of oxygen therapy (3L/min) 20min/day, baclofen and L-Carnitine.The effects alleviate progressively over the course of 2 months a generalised sensation of muscular rigidity of the legs and face with difficulties in the articulations, muscular twitches increasing in frequency. She started progressively on a treatment with Modopar (62,5mg q3d). The results were spectacular after 2 weeks she recuperated fluid motion in her legs, the involuntary muscular contractions disappeared, but there was also improvement in her vigilance and in the fatigue. She stopped the Baclofen without forfeiting anything in her muscular state. After 4 months of the treatment with L-Dopa the effects on her vigilance are maintained with the total hurt of the hypersomnia. She can cut down her intake of Tramadol extended release threefold. Whereas before she thought about stopping all of her professional activities, she is now able to pursuit her professional life with efficacy. The oxygen therapy is maintained as well as the L-Carnitine for their action on muscles, because cutting down this part of the treatment lead to an increase in muscular pain.Discussion1 Identifying dystonia as a frequent and evocative manifestation of EDSDystonia should be looked for in any patient diagnosed with EDS. It even contributes to its diagnosis. On the other hand, when dystonia is present in a patient often associated with psychiatric problems one should think of the possibility of EDS as a diagnosis and inquire about the other evocative signs diffuse overall pain, fatigue, hypermobility, cutaneous fragility, joint pr oblems, hemorrhages and familial cases.2 Reflections on the pathophysiologyWe fancy that the alteration in proprioception plays a large part in the clinical manifestation of EDS. The receptors placed in a more elastic tissue, bony in its thickness, easily deformed and compressed, having lost their elasticity (with a loss or attenuation of the elastic recoil),which do not or not well (not enough or too much) to solicitations. This is particularly true for the skin, which is the most important organ for the postural proprioception and for movement. This is also very true for the attend of muscular activity via neuromuscular connections. This receptor dysfunction is also a plausible commentary for the anarchy within the autonomic anxious system, peculiarly the crises of tachycardia and hypotension due to a loss in reactivity of the carotid fistulous withers receptors implanted in altered collagen. This explanation can be expand towards the mechanism causing dyspnea at effort, as the mechanoreceptors of the joints do not transmit the proper signals to the respiratory centers. One of the arguments in favor of this explanation is the positive effect special compressive clothing has on the proprioceptive determine of the limbs (less falls, fewer luxation of the shoulder and fingers) and the improvement of the respiratory difficulties when wearing these clothes on the trunk. It is logical to interpret dystonia by flair of the same mechanism and the vile information which is received by the specialized area of central nervous system. The positive effect observed by Roland Jaussaud (10) on a patient presenting with permanent, multiple, involuntary movements which completely ceased after starting to wear the special EDS compressive clothing. An association between dystonia and dysautonomia has often been made (11). This corresponds to our observations made in consultation, especially in the instances that our patients came to call their EDS crises. These crises are often accompanied by postural orthostatic hypotension (POTS) which plays an important role in the sensation of fatigue. (7,12). They are habitually painful, even very painful. These observations suggest an intricate pathophysiological relationship between dystonia, dysautonomia and pain in Ehlers-Danlos syndrome which become the main therapeutic focus.3 How to treat dystonia in EDS?The treatment of the proprioceptive problems (clothes and inlays), of the pain (inlays, local treatments to be preferred over the general route), of the fatigue (mostly oxygen therapy) and of the autonomic dysfunction by way of beta-blockers at low dose (13) seems to be a necessary prerequisite to be adjusted towards each patient individually. The specific treatment with anti-Parkinson medications have mostly been followed by their effects included on their effects in grand dystonic crises. The observation of positive effects orthogonal of dystonia bears two questions Firstly the role of dystonia it self on fatigue by way of less muscular activity and a better automatic lead of movement, but also the role of dopamine as a hint itself in this systemic disease.ConclusionsManifestations of dystonia in EDS is an important adjunct to further diagnosis and treatment, the understanding of its pathophysiology of this complex disease, which is little or poorly diagnosed, neutering considerably life quality of the patients suffering from it and a source of many disabling situations.The integration of all the manifestations of dystonia into the symptomatology of EDS enriches the clinic of this syndrome and furthers/advances new therapeutic perspectives in a particularly hard to treat pathology. L-Dopa seems to have positive effects that transcend those researched on dystonia itself.
