RESUMO
A patient with human immunodeficiency virus (HIV) infection presented with multiple cutaneous lesions on upper extremities, trunk, face and with ulcers involving oral mucosa. Histoplasma capsulatum was isolated in culture from scrapings from both cutaneous as well as oral mucosal lesions. The patient responded well initially to the treatment with Amphotericin B followed by itraconazole; however, lesions recurred after three months with the further deterioration of immune status of the patient indicated by decline in CD4 counts. The same treatment was restarted and the patient is still being followed-up.
RESUMO
The rate of surgical site infections and the frequency of various pathogens causing surgical site infection with their antibiotic resistance pattern in general surgery units were studied. In the period from May 2001 to July 2002, 190 patients admitted for surgery (clean and clean-contaminated elective cases) were assessed preoperatively, intraoperatively and postoperatively. Normal microbial flora was studied within 24 to 48 hours of admission and patients were followed up to 30 days postoperatively. Infected wounds were studied bacteriologically and clinically. The overall infection rate was 8.95%. Surgical site infection rate was 3.03% in clean surgeries and 22.41% in clean-contaminated surgeries. Significant increase was seen in surgical site infection rate with an increase in preoperative stay. The increase in duration of surgery was associated with a significant rise in the rate of surgical site infection. Surgical site infection rate was much higher (22.41%) in cases where a drain was used than in non-drained wounds (3.03%). The most common isolate was Staphylococcus aureus followed by Pseudomonas aeruginosa.
