First six cases of neonatal group B beta-haemolytic streptococcal sepsis in GHKL & Maternity Hospital K.L. were reported and in one third, it was fatal. Five of the cases were 'early - onset' type and one was 'late - onset' type. While maternal infant transmission of the disease is important in the 'early - onset' type, environmental sources of infection are also significant. No gestational age or birthweight is spared from the disease. Finally, there are cases of 'early - onset' GBS sepsis presenting like hyaline membrane disease of the newborn and it is important to find ways to distinguish them which so far has not been satisfactory.
Lactic acid concentration was determined in 37 specimens of cerebrospinal fluid by gas liquid chromatography. It was found to be raised (30 mg/dl) in 15 specimens from culture positive cases of bacterial meningitis and one of fungal meningitis. It was < 30 mg/dl in cerebrospinal fluid from four cases of viral meningoencephalitis and 10 contaminated specimens. It was also raised in two specimens from culture negative cases. Determination of cerebrospinal fluid lactic acid concentration by gas liquid chromatography provides a useful, additional test in the diagnosis of bacterial meningitis
Bacterial skin infection was studied in 239 children between the ages of 1 and 12 years in an urban squatter area in Kuala Lumpur over a period of three months (January - March 1983). 62 children presented with dermatological problems, 33 of which were clinically diagnosed as pyoderma. Microbiological examination of swabs from the lesions yielded mixed growth from 54.5% (18/33) specimens. Beta-haemolytic streptococci were isolated from 63.6% (21/33) and Staphylococcus aureus from 54.5% (18/33) specimens. All streptococcal isolates were grouped with a commercial kit, the Streptex (Wellcome). 81% (17/21) belonged to Lancefield's group A, 90% of which were not M or T typable by the standard international set of antisera. Urine analysis, pharyngeal swab culture and determination of anti-streptococcal antibody titre were also performed for children with positive skin cultures for group A streptococcus. 6% (2/33) of children with impetigo developed acute glomerulonephritis, requiring hospitalization.
