Disseminated toxoplasmosis in an immunocompetent patient from Peruvian Amazon.

We report a case of severe toxoplasmosis in an immunocompetent patient, characterized by pneumonia, retinochoroiditis, hepatitis and myositis. Diagnosis was confirmed by serology, T. gondii in thick blood smear and presence of bradyzoites in muscle biopsy. Treatment with pyrimethamine plus sulfadoxine was successful but visual acuity and hip extension were partially recovered. This is the first case report of severe toxoplasmosis in an immunocompetent patient from Peru.

Electronic circuit breaker for recording and stimulation from same electrode

An electronic circuit breaker is described which allows stimulation and recording through the same electrode and automatically shifts modes with a minimal delay. This circuit has been used efficiently in the experimental study of convulsive activity (Kindling).
