Nimodipine is a 1,4-dihydropyridine derivative that shows preferential cerebrovascular activity in experimental animals. Clinical data suggest nimodipine has beneficial effect on the neurologic outcome of patients suffering an acute ischemic stroke. Our double-blind placebo-controlled multicenter trial was designed to assess effects oral mortality rate and with One hundred sixty-four were randomly allocated receive either tablets (30 mg q.i.d.) or identical placebo for 28 days. Treatment...

Ataxic hemiparesis with cerebellar-like features has been reported following infarction or hemorrhage of the thalamus. We describe five patients incoordination and corticospinal tract signs in limbs opposite a dorsolateral thalamic hemorrhage. In four extended superiorly into lateral ventricle, adjacent paraventricular region, upper medial parts posterior limb internal capsule. Instead cerebellar dysfunction, these exhibited directional errors movement that improved distinctly when performed...

A clinical and pathological report of a patient who died 15 days after suffering classic heat stroke is presented. The picture was flaccid quadriplegia with anhidrosis sphincter disturbance. most severe lesions were to be seen in the anterior intermedio-lateral horns spinal cord. Hyperthermia only physiopathological mechanism demonstrated patient. It suggested that motor neurons vegetative cord are specially sensitive hyperthermia.

The case of a 65-year-old woman with polyneuropathy, organomegaly, skin changes and monoclonal gammopathy IgG-lambda type is described. This patient developed an acute carotid obliteration during oral anticoagulation despite absence vascular risk factors. Macroangiopathy has been described as rare systemic manifestation POEMS syndrome (polyneuropathy, endocrinopathy, spike changes), affecting the coronary lower limbs arteries. To our knowledge, this second cerebrovascular manifestation.

A 21 year old male, well-nourished and non-alcoholic, died after five weeks illness. He had suffered epileptic fits, bilateral internuclear ophthalmoplegia, bulbar pontine paralysis, tetraparesia, ataxia dystonia. CT brain scan showed low density lesions of the striatum bilaterally. Post-mortem studies revealed pathological anomalies compatible with Leigh9s disease, although presence haemorrhages involvement mamillary bodies could also suggest Wernicke9s encephalopathy.

A previously healthy man developed an acute encephalopathy with coma after a single wasp sting on his chin. Brain CT showed bilateral pallidostriatal radio-lucencies. He died 72 hours the no evidence of primary cardiorespiratory failure or allergic reaction. Pathological findings were necrosis and diffuse neuronal damage in frontal, temporal, parietal cortex. The neurotoxic effect poison, together hypersensitivity are most likely explanations for this unusual encephalopathy.

Abstract This investigation seeks to understand how the interfaces between fracture orthoses and body affect relative motion user device. Excessive can inadvertantly load prevent healing. Identifying that minimize will inform designs of future orthoses. Three types were tested: a thigh corset, sling loaded ischium, patellar tendon. Eighteen able-bodied participants fitted with an adjustable Interface Testing System (ITS) redirected loads away from foot lower leg more proximal parts using...
