An outbreak of acute hemorrhagic conjunctivitis (AHC) occurred in Rio de Janeiro in 2004. Coxsackievirus A24v (CA24v) was identified as the etiologic agent, and partial sequences from the VP1 gene show that the isolates are closely related to CA24v viruses that previously caused AHC epidemics in South Korea and French Guiana.

background: thrombolytic therapy is the only approved treatment for acute cerebral ischemia. the hemorrhagic transformation is the greatest complication of this treatment, which may occur after recanalization of occluded artery. the aim of this study was to determine factors associated with clinical improvement and worsening in patients with acute ischemic stroke treated with intravenous thromb...

Acute hemorrhagic leukoencephalitis of Weston Hurst is at the extreme end of the spectrum of demyelinating diseases. It typically follows a viral upper respiratory infection and evolves rapidly to coma and death. "Ball and ring" hemorrhages appear in the centrum semiovale of the brain, associated with mononuclear and neutrophil infiltrates, surrounded by demyelination spreading out from fibrin-...

The differential diagnosis between multiple sclerosis and acute disseminated encephalomyelitis has major prognostic and therapeutic implications for the patient. As originally defined, acute disseminated encephalomyelitis is an acute monophasic disease that requires early anti-inflammatory treatment, whereas long-term immunomodulatory therapies are considered unnecessary due to the self-limitin...
