Objective:To study organism-specific platelet response and factors affecting survival in thrombocytopenic very low birth weight (VLBW) babies with sepsis.Study Design:Very low birth weight babies (birth weight <1500 g) admitted to a single level-three intensive care unit from January 2000 to December 2005 were prospectively evaluated for sepsis by rapid screen test, blood counts and blood culture. In thrombocytopenic babies, organism-specific platelet response and its effect on various platelet parameters were evaluated. In addition, morbidity, mortality and factors affecting survival were studied.Result:Sepsis was diagnosed in 230 of 620 (37%) patients. Gram-positive sepsis occurred in 20% (46/230), Gram-negative in 71% (164/230) and fungal in 8.6% (20/230) of patients. Thrombocytopenia was observed in 67% (155/230) of babies. The frequency and duration of thrombocytopenia were more with Gram-negative and fungal infections. The incidence of persistent bacteremia, multiorgan failure and death was more in thrombocytopenic neonates (P<0.01). The incidence of multiorgan failure and death was directly related to the duration of thrombocytopenia. On multiple logistic regression analysis, poor prognostic factors include a high SNAP score at admission, a severe drop in platelet count at onset of sepsis, a low platelet nadir, a prolonged duration of thrombocytopenia, a need for platelet transfusion, less number of days off ventilation and a prolonged stay in the hospital.Conclusion:In thrombocytopenic VLBW babies with sepsis, organism-specific platelet response is seen. In addition, persistent bacteremia, multiorgan failure and death are more in these babies, and survival decreases with the increased severity and duration of thrombocytopenia, with prolonged ventilation and increased need for platelet transfusions [ABSTRACT FROM AUTHOR]

Meconium peritonitis is a chemical reaction of peritonium to meconium which occurs due to leakage of meconium into peritoneal cavity as a result of perforation of intestines antinatally which gets subsequently sealed. In the present retrospective study, 39 cases of neonatal peritonitis were studied. Meconium peritonitis was diagnosed if a) abdominal X-ray showed diffuse calcifications (b) abdominal paracentesis showed meconium aspirate and c) leprotomy examination. Twenty (51.3%) out of 39 cases of neonatal peritonitis were found to have meconium peritonitis. These included 14 boys and 6 girls, birth weight ranged from 1500 gms to 3200 gms and mean age of presentation included abdominal distension in 100% cases, H/O not passing meconium in 50% cases, Ascites in 45% cases and vomiting in 40% cases, 30% presented with abdominal mass. Pseudocyst formation on X-ray was seen in 23% cases which was much higher than reported in world literature. Overall mortality in meconium peritonitis was 80%. The incidence of meconium peritonitis in this part of country in much higher than reported in Western and Indian literature. The high incidence may be due to underlying cystic fibrosis because Kashmir has a more homogenous population and consanguinity is very common. A prospective study including sweat chloride testing needs to be undertaken to look into the cause for proportionately higher occurrence of meconium peritonitis in Kashmir with particular reference to cystic fibrosis.
