We describe a retrospective study on hepatitis-B immunization in the Indonesian workers' children of Mobil-Oil Indonesia Lho' Seumawe and Lho'sukon, North Aceh. Data were obtained from medical records and included all children in the 0-15 years age group who had been immunized against hepatitis B types and schedules of vaccines, pre-immunization seromarkers, and anti HBsAb after the third immunization were recorded. For hundred and twenty children had received three doses of,hepatitis B vaccines; 180 children had them at 0, 1 and 2 months and the rest at 0, 1 and 6 months. Type of vaccine used was hunian plasma derived vaccine with a dosage of 5 µg per shot All of them (except the newborns) were tested and had seromarkers negative to hepatitis 8 infection prior to immunization. Testing for immune response (HBsAb) 2-6 months after the third immunization could only be done in 213 children, where 168 (78.9%) showed HBsAb titer> 10 miU/ml, 5 (2,30Al) had HBsAb < 10 miU/ml, and the remaining 40 (18,8%) showed no seroconversion. Of those 40 children who did not seroconversed, 31 were given a fourth dose, and 14 children were retested for their HBsAb titre. Seven children had positive responses and the rest remained negative.

We performed a prospective study on the association between acid-base balance and asphyxta based on Apgar scores in 45 newborn babies admitted to the Division of Perinatology, Pirngadi Hospital, Medan, from January 1 to February 28, 1993. Blood gas analysis was done on blood obtained from umbilical artery. Based on 1st and 5th minutes Apgar scores, 40 (88.9%) and 21 babies (46.7%}, respectively, had asphyxia. Relation to acid-base balance was determined with the sensitivity of the 5th minute Apgar score in predicting acidotic states. It was found that Apgar score had sensitivity of 57.7% and specificity of 68.4% in predicting the acidotic states. Apgar score of > 7 was unable to. exclude the possible acidosis in 45% of cases (negative predictive value 54.1%). Gestational age had no influence on Apgar Scores. Apgar score was more sensitive to eliminate suspected acidosis in term neonates than in preterms. We recommend to perform umbilical arterial blood gas analysis to determine acidotic state in high risk newborn infants.
