Randomized Controlled Trial Clinical Trial
Effectiveness of adjunctive treatment with steroids in reducing short-term mortality in a high-risk population of children with bacterial meningitis.
Bacterial meningitis is still an important cause of death and/or persistent nervous system damage in children living in developing countries. The aim of the study was to evaluate the effectiveness of steroids in reducing mortality and neurologic sequelae in children affected by bacterial meningitis within the context of a developing country (Mozambique), where the case-fatality rate of this disease is over 30 per cent. Seventy children with bacterial meningitis were randomized to receive either conventional antibiotic therapy or antibiotic therapy plus dexamethasone. ⋯ A favourable trend in terms of fewer serious neurologic abnormalities was also observed among survivors in the steroid treated patients (5/26 v. 7/24). Fever and CSF abnormalities also disappeared more rapidly in patients receiving dexamethasone (P < 0.05). This study showed that the beneficial effect of adjunctive steroid therapy in children with bacterial meningitis can be even more important in areas where the case-fatality rate of this disease is still very high.

Comparative Study
Trial of co-trimoxazole versus procaine penicillin G and benzathin penicillin + procaine penicillin G in the treatment of childhood pneumonia.
This study, which aimed to assess the results of three different regimens in the treatment of pneumonia, was carried out at the Pediatric Outpatient Department of Capa Children's Hospital in Istanbul on 151 patients aged between 4 months and 14 years. The first group (n = 46) received co-trimoxazole orally for 10 days and the second group (n = 63) procaine penicillin G in intramuscularly for 10 days. ⋯ While the best results were obtained with penicillin procaine G, no statistically significant difference was found between this regimen and co-trimoxazole therapy (chi 2 = 0.305023 P = 0.5). We suggest that co-trimoxazole is easy to administer and cost effective in the ambulatory treatment of pneumonia in children.

An assessment of the incubators in use at the Kathmandu Maternity Hospital neonatal unit was undertaken; this was followed by a prospective survey of neonatal temperatures on the unit. In the incubator assessment 11 studies were carried out in five incubators. Three of the thermostats in the five incubators did not work at all and those in the other two incubators were more than 3 degrees C inaccurate. ⋯ In the prospective survey of temperatures a high incidence of hypothermia was found on the neonatal unit at the time of first temperature measurement (64 per cent had a rectal temperature of < 36 degrees C). A significant association between admission hypothermia and mortality was noted. Sixteen per cent (10/64) of babies admitted with temperatures < 36 degrees C died within the first week, compared to 0 (0/36) of those admitted with temperatures > or = 36 degrees C.

In 1950 a whole-cell pertussis vaccine was introduced in Cape Town and was followed by a marked decline in reported whooping cough mortality and morbidity. This resulted in reduced awareness of whooping cough as a clinical problem and, in recent years, no routine diagnostic tests for Bordetella pertussis have been performed. An outbreak of whooping cough occurred in Cape Town between 1 June 1988, and 31 May 1989, with 292 children admitted to hospital for whooping cough during this period (hospital admission rate in children under 5 years of age = 187 per 100,000). ⋯ Coverage studies for pertussis vaccine in Cape Town indicated that between 81 and 93 per cent of children were fully immunized by 13 months of age. These findings suggest that, since its introduction, the whole-cell pertussis vaccine produced in South Africa has been highly effective in controlling whooping cough. However, it was not able to prevent a moderate scale outbreak, even in the presence of high vaccination levels.
