Case report. Nattrassia mangiferae endophthalmitis.
Nattrassia mangiferae is a plant pathogen that is also known as a cause of skin infection in humans. Reports of invasive human infection are extremely rare. A 60-year-old-immunocompetent patient presented with endophthalmitis one week after the left eye was injured by a piece of grass. Cultures of an aqueous tap grew N. mangiferae. The patient responded to oral ketoconazole. This suggests that N. mangiferae may be an invasive pathogen in plant penetration injuries and that ketoconazole may be an alternative treatment, especially in countries with poor resources.

Late complications of Candida (Torulopsis) glabrata fungemia: description of a phenomenon.
Complications occurring > 1 month after Candida glabrata fungemia have not been studied. We conducted a study to determine the frequency and morbidity of complications of C. glabrata bloodstream infections occurring > 1 month after infection. Late complications were common (incidence 9.9 per 100 patient years), and most often occurred within the first year. In a multivariate analysis, late complications were associated with the presence of diabetes mellitus [odds ratio (OR) 12.2; 95% confidence interval (CI) 1.2-130] and chronic renal failure (OR 14.7; 95% CI 1.2-184). These data suggest that careful long-term follow-up of patients with C. glabrata fungemia is important and present an opportunity to explore secondary prophylaxis.

Cryptococcus neoformans meningoencephalitis in African children with acquired immunodeficiency syndrome.
BACKGROUND: The number of children with AIDS in Africa is high. Such children may be at risk for cryptococcal meningoencephalitis, but data are scarce regarding this disease in our population. METHODS: We examined records of HIV-infected children (< or =16 years) diagnosed with cryptococcal meningoencephalitis in Harare, Zimbabwe, between 1995 and 2000. To elucidate features unique to pediatric disease, the children were compared with adult patients with HIV-associated cryptococcal meningoencephalitis. RESULTS: Thirteen children presented to our institution with headache (85%), nuchal rigidity (69%), vomiting (46%), impaired mental status (38%), convulsions (38%) and focal neurologic signs (23%). The mean duration of symptoms before diagnosis was 9 days. Cerebrospinal fluid examination revealed normal white blood cell counts in 64%, protein value in 67% and glucose concentration in 57% of patients. Children were more likely than adults to have seizures (38% vs. 11%, P = 0.02) and normal cerebrospinal fluid protein (67% vs. 10%, P < 0.01). The in-hospital mortality was 43%. Convulsions (P = 0.05) and impaired mental status (P < 0.01) were associated with increased mortality CONCLUSIONS: Cryptococcal meningoencephalitis in African children presents acutely or subacutely, can have a fulminant picture and is consistent with progressive meningoencephalitis.
