meningitis is one of the most important causes of infant mortality and its early and proper diagnosis is of great importance, but there are currently no laboratory facilities optimized and fast in detection of meningitis pathogens. the current standard of bacterial meningitis diagnosis is microscopic examination and cerebrospinal fluid (csf) culture. this research aimed at isolating the most co...

conclusions due to the increasing resistance of pathogens to usual empirical antibiotics, it is reasonable to stress upon preventive measures, so that a minimum number of neonates develop sepsis. results coagulase-negative staphylococci (cons) were the most prevalent pathogens isolated from blood specimens in early and late-onset disease. escherichia coli and klebsiella were the most causative ...

hyperbilirubinemia is a common problem in neonates and causes serious complications. thus, serial measurements of bilirubin should be done. this assessment is done through two methods of laboratory measurement in serum sample and transcutaneous bilirubinometer. this descriptive study compared transcutaneous bilirubin assessment and laboratory serum bilirubin. bilirubin level was assessed among ...
