Abstract
Out of 6586 live born babies, 736 babies with jaundice were studied from 1st July 1996 to 30th June, 1997, in a city based medical college nursery. Physiological jaundice was present in 8.92% of all live born babies and accounted for 79.89% of babies with jaundice. Breast milk jaundice and prematurity were next common causes responsible for 5.29% each of all cases with neonatal jaundice. Septicaemia caused jaundice in 4.75% cases. Among the babies with jaundice appearing between day 4 and day 7 of life, breast milk jaundice was the commonest cause occurring in 49.25% cases. The last entity surfaced probably due to exclusive breastfeeding recently initiated in the baby friendly hospital nursery.

Abstract
Out of 6319 live born babies, 310 (4.9%) with high risk factors and with clinical suspicion of sepsis were studied for incidence pattern of neonatal infections. Incidence of neonatal infection was 2.56% in normal weight babies and 8.42% in low birth weight babies. Total culture positivity was 48.38%. Klebsiella was the most frequent offender, followed by Staph aureus and Staph epidermidis. Majority of klebsiella species were sensitive to ceftriaxone (86%), amikacin (84%) and ceftazidime (80%). Ceftriaxone was effective against Staph aureus (95%) and Staph epidermidis (95%). Overall fatality was 17.1%, distinctly higher in low birth weight group (22.06%) than normal weight group (6.18%).

Abstract
Early neonatal morbidity & mortality were studied in 7972 viable live born babies over one year period in Medical College, Calcutta. Early neonatal morbidity and mortality rate were 66.85 & 32.86 respectively. About 48% of Early neonatal deaths occurred in 1st 48 hours & 80% within first 72 hours of life. Early neonatal mortality rate per 1000 was maximum in babies born of a primi (43.03) and grand multiparous mother (103.89); maternal age less than 20 yrs. (44.15), and more than 30 yrs. (46.04) & in multiple pregnancy (142.85). It was highest in breech delivery (114.28) & with maternal disease like dribling (179), hypertension (146) & APH (116). Birth asphyxia contributed 65.26% of early neonatal deaths, followed by septicaemia (10.3%). Klebsiella was the most common (55%) organism.
