Background. The incidence of sepsis among newborns ranges from 1–12 to 38 per 1,000 live births in the world according to scientific literature [1, 2]. The clinical case demonstrates the features of the newborn organism sensitivity and the therapeutic and diagnostic process difficulties. Clinical case description. The boy was born on the 37th week of gestation, 1st of twins, with body weight 3330 g, height 51 cm, APGAR score 8/9 points.He was on breastfeeding. His condition has deteriorated rapidly on the 9th day of life. The condition was severe due to intoxication syndrome, necrotising enterocolitis (NEC) manifestation, further development of systemic inflammatory response syndrome and multiple organ dysfunction syndrome. Severe pain syndrome and movement restraint in limbs have appeared on the 20th day of life. X-ray imaging: NEC signs, multiple osteomyelitis foci in the limbs.Conclusion. Modern adequate diagnosis and justified treatment tactics have led to positive outcome: child’s condition has improved, body weight has increased, pain syndrome has been managed, the volume of movements in the limbs has increased, inflammatory markers have stabilised. The child was discharged from hospital in satisfactory condition at the age of 2 months.

The article describes clinical observation of treatment of a premature infant with chyloperitoneum. Accumulation of fluid in the abdominal cavity was diagnosed prenatally at 31–32 weeks of gestation. Premature surgical delivery was performed at 34– 35 weeks due to the high risk of antenatal fetal death. Paracentesis with fluid analysis was done; chylous exudate was confirmed. Total parenteral nutrition, octreotide and drainage of the abdominal cavity were used during conservative treatment. It was decided to perform a surgery as the therapy was ineffective. At the age of 2 months and 7 days laparotomy was conducted, abdominal organs were revised, lymph ducts were ligated, and abdominal cavity was drained producing a positive effect. The fluid outflow was terminated and the child was discharged in a satisfactory condition.

The article describes two cases of children operated on for the biliary atresia (BA) on days 56 and 33 of their life. One child after the Kasai surgery had liver transplantation at the age of 1 year and 2 months because of the deterioration of his liver synthetic function which was manifested by the clotting factor deficiency. Another child (5-month old) does not need any transplantation at present. The article defines “red trackers” for the immediate examination of a child for biliary atresia.
