Objective: To assess endothelial dysfunction in patients with MS and to investigate whether plasma from patients with MS induces endothelial cell dysfunction in vitro.

Background: Endothelial cell dysfunction may contribute to the pathogenesis of MS. Elevations of soluble adhesion molecules intracellular adhesion molecule, vascular cell adhesion molecule, and platelet-endothelial cell adhesion molecule-1 (CD31) have been reported as markers of blood-brain barrier (BBB) damage in MS, but direct assay of endothelium has been difficult.

Objective And Importance: Adrenocortical carcinoma (ACC) is rare in the pediatric population, and brain metastasis seldom occurs.

Clinical Presentation: The authors report a case of metastatic ACC to the brain in a 9-year-old patient who had an adrenal cortex neoplasm removed at 4 years of age, and was free of symptoms for 5 years. Two weeks before admission she complained of blurred vision in both eyes.

Ischemic optic neuropathy occurred in a patient following liposuction. Perioperative anemia and hypotension may be the cause of this complication. Correction of anemia with transfusion improved the hemoglobin and hematocrit but the right eye remained blind.

A patient with advanced AIDS presented with right conjugate gaze palsy and impaired adduction on left gaze (the one-and-a-half syndrome). The responsible pontine lesion involved the ipsilateral abducens nucleus and the adjacent medial longitudinal fasiculus (MLF), as demonstrated by magnetic resonance imaging (MRI). Tuberculosis (TB) was the etiology of the brainstem lesion.

Objectives: Persisting aphasia presenting as an isolated inability to vocalize is an uncommon presentation of simple partial status epilepticus and only eight such cases have been reported over the past 40 years.

Methods: We studied a patient with a 5-year history of recurrent episodes of inability to talk, without any other motor or cognitive impairments. Episodes lasted as long as 24 h, interictal EEGs were normal and she was diagnosed as a conversion disorder.

MRI scans were compared between 71 Hispanic and 73 white non-Hispanic patients with National Institute of Neurological Disorders and Stroke probable AD. Analysis of covariance controlled for age, sex, education, and Mini-Mental State Examination scores indicated that ventricular size was smaller in Hispanic than white non-Hispanic patients (p = 0.0003).

Background: Controversy exists regarding the use of dopamine receptor agonists in elderly patients with Parkinson's disease because of concern about a high rate of intolerable side effects.

Methods: A retrospective chart review was used to examine our experience with dopamine agonist use in the very elderly by identifying patients in our Parkinson's disease database who were over the age of 80 years and who had received agonists. Sixty-nine patients were identified who had 120 separate trials of agonist therapy.

Glossopharyngeal neuralgia (GPN) is characterized by a severe lancing pain in the posterior pharynx, tonsillar fossa, and base of the tongue. It is induced frequently by swallowing and yawning. GPN has not been described previously in MS patients.

Pregnancy in patients with Parkinson's disease (PD) is a rare occurrence. Previous reports based on retrospective analysis suggest that pregnancy may have a deleterious effect on PD. We describe the effects of pregnancy on the symptomatology of a 33-year-old woman with PD using quantitative neurologic and quality-of-life scales prepartum, intrapartum, and postpartum.

We report a 48-year-old woman with a 17-year history of PD who developed a peripheral sensory-motor neuropathy secondary to chronic administration (8 years) of amantadine. Discontinuation of amantadine resulted in resolution of trophic skin ulcers, paresthesias, and distal weakness. Amantadine may be hazardous to patients with severe and chronic livedo reticularis.

An elderly hypertensive man had extensive bilateral infarction in the distribution of the anterior cerebral arteries. The circle of Willis was fully formed, but occlusion of the dominant anterior cerebral artery, aggravated and perhaps caused by postlaparotomy hypotension, produced the dramatic lesions, causing akinetic mutism. This stroke pattern occurs in various settings and does not require an anomalous azygous unilateral supply to both anterior cerebral arteries.

Progressive supranuclear palsy (PSP) is a progressive neurodegenerative disorder with no effective treatment. Dopaminergic agents occasionally produce transient symptomatic improvement. The authors report the results of pramipexole treatment (4.

Skin eruptions have been reported with the use of all antiepileptic drugs and there is a significant risk of cross-reactivity between these agents in causing serious eruptions such as Stevens-Johnson's syndrome. Gabepentin is usually considered a safe agent for patients with a previous history of drug allergies and there have been no cases of skin eruption reported to the gabapentin post marketing surveillance. We report a patient who had severe Stevens-Johnson's syndrome induced by phenytoin and later by carbamazepine.
