RESUMO
A 17-year-old female presentedwith acute disseminated encephalomyelitis (ADEM), a demyelinating disease ofthe central nervous system, fourweeks after receiving a meningococcalvaccination. The report highlights a rare but known presen- tation following routine vaccination that requires a high degree ofsuspicion in recognition and management. Early initiation of steroid therapy, followed by a steroid taper over one month resulted in a favorable outcome of complete neurological recovery.

A 24-year-old female who was recently diagnosed with Type 1 diabetes mellitus (TiD) presented with a five-year history of visible gait disturbance and slurred speech. Her neurologic examination was remarkable for dysarthria, bilateral nystagmus, dysdiadochokinesia, finger-nose incoordination, heel-knee incoordination, and ataxic gait. A brain MRI disclosed diffuse cerebellar atrophy. Her serum antiglutamic acid decarboxylase (GAD) antibody titer was elevated. Antinuclear antibody (ANA) test was positive with atiterofl:2560 and a speckledpattern. Genetictests for inherited ataxia, including Friedreich ataxia, were negative for mutations. Her cerebrospinal fluid (CSF) analysis revealed oligoclonal bands and she had a positive CSF GAD65 antibody. A diag- nosis of GAD antibody-induced cerebellar ataxia was considered. She developed GAD autoimmune antibody positive TiD during the course ofher dis- ease. GAD antibody-associated cerebellar ataxia is a rare entity, however it should be considered as a possibility in patients with associated autoimmune disease and positive anti-GAD antibody.

OBJECTIVE: Ascertain the incidence, predictors and consequences of early (within 48 hours of admission) and nosocomial pneumonia among critically ill patients with stroke. METHODS: Medical records of critically ill patients with acute stroke were reviewed. Predictors and consequences of pneumonia were determined with analysis of variance. RESULTS: 55 patients, aged 33 to 91 (median 74) years, were admitted. The stroke was located at the brainstem in 14 (26.4%) patients. Nine patients (16.4%) had early pneumonia and additional 17 patients (30.9%) developed nosocomial pneumonia. Patients with brain-stem stroke were more likely to develop early pneumonia (p =.04). Nosocomial pneumonia incidence was higher in patients who failed swallowing evaluation (RR = 6.3, 95% CI: 0.9-43.0) and in those who were intubated (58.6% v 0%, p =.00008). Also, nosocomial pneumonia was associated with longer duration of mechanical ventilation and prolonged hospital stay. Nineteen patients (34.5%) died at the hospital. They were more likely to be older (median 77 versus 69 years, p =.03) with higher admission acuity of illness. CONCLUSION: Pneumonia complicated stroke in 47% of critically ill patients and adversely impacted the duration of mechanical ventilation and overall length of hospital stay. Aggressive preventive measures are needed to reduce pneumonia occurrence in stroke patients.

Progressive multifocal encephalopathy (PML) is a rare demyelinating disease that typically presents in immunodeficient patients. We report a case of a previously healthy 62-Year-Old woman who suffered from an unsteady gait, throbbing headaches, and progressive left-sided weakness and numbness. Stroke was initially suspected based on imaging and symptoms. A series of follow-up magnetic resonance images of the brain showed a right parietal lesion growing in size as the patient became unable to walk and experienced increasing lethargy and confusion. A biopsy of the lesion was positive for the John Cunningham virus (JCV). A diagnosis of PML was made and she was started on mefloquine. No improvement was seen on this treatment and her condition worsened. Although PML remains uncommon in immunocompetent individuals, it cannot be ruled out based on their immune status. Although the exact cause remains uncertain, underlying or transient states of immunosuppression may be responsible for reactivation of the JCV in these patients.
