Duggan, M. B., and Khwaja, M. S. (1975). Archives of Disease in Childhood, 50, 130. Neonatal primary peritonitis in Nigeria. Six cases of neonatal primary peritonitis admitted to Ahmadu Bello Hospital, Zaria, between January 1972 and July 1973 are reported, of whom 4 survived. All patients had evidence of umbilical sepsis, while 2 had erythema marginatum, which has not previously been reported in this condition. The importance of peritoneal aspiration and x-ray of the abdomen in establishing the diagnosis is stressed, as is prevention of umbilical sepsis by increased health education.
