Invasive pneumococcal infection in children.

Streptococcus pneumoniae infections can involve multiple organs and cause high mortality and morbidity. In this retrospective study, we reviewed patients with invasive pneumococcal infection in the pediatric department of a teaching hospital in Taipei. From 1984 to 1998, 81 children with invasive pneumococcal infection were hospitalized. Twenty-eight patients had meningitis, 27 had pneumonia with pleural effusion, 60 had sepsis, and 4 had arthritis. Thirty-eight patients had more than one site of infection. Most of our patients (81.7%) were below 5 years of age. Pneumococcal infections were more common from October to March. Eight patients had a history of trauma that correlated with the site of infection. Thirteen patients (16.0%) expired and 20 (24.7%) had severe sequelae. Multi-regression analysis found that meningitis and complications were independent variables that affected the outcome. The percentage of penicillin-resistant strains increased beginning in 1990 and accounted for about four-fifths of the infections in the final 2 years of the study. Since invasive pneumococcal infections in children may have a poor prognosis and penicillin-resistant strains have become increasingly common, early and adequate antibiotic therapy should be given as soon as possible.

Pediatric nosocomial fungal infections.

During a period of twelve years (1984-1995), ninety-seven pediatric patients experienced 107 nosocomial fungal infections at Mackay Memorial Hospital. The nosocomial fungal infection rate in pediatric patients was lower than that of the hospital as whole, but it increased significantly. The average rate in the last three years (1993-1995) was 1.20 per thousand discharged patients, 10 times that of the first three years (1984-1986). Two-thirds of the patients were below one year of age. Half of the infections occurred in Intensive Care Units. The bloodstream was the most common site of infection (40.2%), followed by the urinary tract and skin. Important underlying diseases included malignancies, prematurity, and congenital anomalies. Common risk procedures included total parenteral nutrition (43.3%), endotracheal intubation (29.9%), central venous catheterization (25.8%), operation (14.4%). Near 90% of the patients had previously received antibiotics. Candida albicans was responsible for 58.1% of the infections. Thirty-three patients expired, of whom 18 died of the fungal infections. With the trend of increasing nosocomial fungal infections, physicians should be more alert to the possibility of such infections.
