The second case of peritonitis due to Histoplasma capsulatum during continuous ambulatory peritoneal dialysis in Brazil.

This paper reports a case of infection due to Histoplasma capsulatum apparently restricted to the peritoneum in a woman submitted to continuous ambulatory peritoneal dialysis (CAPD).

[Human dermatomycoses in the interior of Rio Grande do Sul in the period of 1988-1992]. / Dermatofitoses humanas no interior do Rio Grande do Sul no período 1988-1992.

The relative frequency of the dermatophytes in the central region of Rio Grande do Sul, Brazil, have changed during a survey carried out from 1988-1992.
