Development of Parkinsonism following exposure to aripiprazole: two case reports

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Introduction: Aripiprazole is a novel atypical neuroleptic used in the treatment of psychosis. A few recent studies have demonstrated an association between the use of aripiprazole and an exacerbation of Parkinsonism, although this relationship is poorly defined. To our knowledge, this is the first case series describing an onset of Parkinsonism in patients without prior history of Parkinson’s diseas

Stroke with neuropsychiatric sequelae after cannabis use in a man: a case report

<p>Abstract</p> <p>Introduction</p> <p>The outcome of cerebral ischemic stroke associated with cannabis use is usually favorable. Here we report the first case of cannabis-related stroke followed by neuropsychiatric sequelae.</p> <p>Case presentation</p> <p>A 24-year-old Caucasian man was discovered in a deeply comatose non-reactive state after cannabis use. A magnetic resonance imaging scan of his brain showed bilateral multiple ischemic infarcts. The patient remained deeply comatose for four days, after which time he developed other behavioral impairments and recurrent seizures.</p> <p>Conclusion</p> <p>Stroke related to cannabis use can be followed by severe neuropsychiatric sequelae. Concomitant alcohol intoxication is essential neither to the occurrence of this neurologic event nor to its severity.</p

Myasthenia gravis in Ceará, Brazil: clinical and epidemiological aspects

A retrospective chart review was performed on patients diagnosed as having myasthenia gravis in Ceará State, Brazil and who were followed from October 1981 to June 2009. Clinical and epidemiologic aspects were evaluated. In this work, 122 patients were studied, of whom 85 (69.7%) were females and 37 (30.3%) were males. The disease duration ranged from five months to 50 years (8.9±8.1 years). Age at the first symptoms varied from 0 to 74 years (31.9±14.4 years). The first main symptoms and signs were ptosis, diplopia and limb weakness. Generalized myasthenia was the most common clinical presentation, but 5.1% (n=6) persisted as ocular myasthenia. Thymectomy was performed in 42.6% (n=52) of myasthenic patients. A thymoma was present in 10 patients. Serum acetylcholine receptor (AChR) antibodies were present in 80% (n=20) of specimens tested. The data presented are similar to those of studies performed in other countries
