The authors studied two patients with Lambert-Eaton myasthenic syndrome (LEMS) in whom the repeated examination did not find specific of LEMS P/Q type voltage-gates calcium channel autoantibodies. The results of clinical testing and electrophysiological examination showed the typical character of movement disorders with the absence of tendon reflexes and signs of disautonomia as well as a decrease in M-response amplitude and phenomena of decrement with low frequency- and increment with high frequency stimulation...

There are few studies reporting the association between hepatitis C virus (HCV) infection and disautonomia. We have evaluated the autonomic cardiovascular function in 12 patients with sensory small-fiber polyneuropathy infected by HCV. The mean age was 49 ± 13 years old. The mean infection time was 9.6 years in six (50%) patients. Thermal and pinprick hypoesthesia was observed in distal legs in all patients. Autonomic symptoms were referred by eight (66.7%) patients. Among patients with abnormal autonomic cardiovascular test, five (41...

Autonomic dysfunction has been already described in patients with SCA3/MJD, but several important questions remain unanswered. The objectives of this study are to determine the frequency and the intensity of autonomic manifestations in SCA3/MJD, as well as to identify possible correlations between autonomic manifestations and genetic and clinical parameters. We have performed clinical and electrophysiological evaluations of 40 patients with SCA3/MJD and 38 healthy controls. We used the Scale for the Assessment and Rating of Ataxia (SARA) and the scales for Outcomes in Parkinson's Disease: Autonomic Questionnaire to quantify the severity of ataxia and autonomic complaints, respectively...

Parkinson's disease concept is classically restricted to a rigid-akinetic syndrome due to a nigro-striatal dopaminergic depletion. This concept ignored the widespread extension of neuropathologic findings across the CNS. Moreover detailed clinical studies showed that patients suffer a constellation of other symptoms and signs such as anosmia, constipation, cardiovascular disautonomia, neuropsychologic and neuropsychiatric disorders, dementia and sleep changes. Taken together these evidences have lead to the idea that Parkinson's disease is a multisystemic disease of the nervous system...

Rats stressed by specific alternation of rhythm in temperature (SART) show various symptoms of disautonomia, increased pulse rates, continuous hypotension, and severe orthostatic hypotension (OH) when they are subjected to postural change. The OH symptoms are improved by muscarinic M2-receptor blockers. In the present study, effects of beta-adrenoceptor blocking agents on OH in SART-stressed rats were investigated. Anesthetized rats were restrained on a board in the supine position, and direct blood pressure and ECG were measured automatically using Fluclet Jr...

The case of a 31 man with acute disautonomia envolving the parasympathetic and sympathetic systems but sparing sympathetic cholinergic division is presented. A Hodgkin lymphoma was diagnosed allowing the diagnosis of a paraneoplastic syndrome.

The disfunction of the autonomic system nervous is a frequent finding in diabetes mellitus. Among objective tests proposed for its diagnosis, those assessing cardiovascular reflexes (cardiovascular tests: CVTs) explore the autonomic functionality by means of a group of standardized manoeuvres of relatively easy execution that study the baroreceptorial reflex arc. In our study, CVTs were performed in a population of 207 diabetic patients with no symptoms of autonomic neuropathy. A computerized automatic system (Cardionomic) was utilized...
