Publication Bacterial Isolates and its Antibiotic Susceptibility Pattern in NICU(Kathmandu university, 2013) Shrestha, S; Shrestha, NC; Dongol Singh, S; Shrestha, RPB; Kayestha, S; Shrestha, M; Thakur, NKABSTRACT Background Neonatal sepsis is one of the major causes of morbidity and mortality among the newborns in the developing world. Objectives To determine the common bacterial isolates causing sepsis in neonatal intensive care unit and its antibiotic susceptibility pattern. Methods A one year discriptive prospective study was conducted in neonatal intensive care unit to analyse the results of blood culture and to look into the sensitivity of the commonly used antibiotics. Results The blood culture yield by conventional method was 44.13% with nosocomial sepsis accounting for 10.79%. 84.08% were culture proven early onset sepsis and 15.95% were late onset sepsis. Klebsiella infection was the commonest organism isolated in early, late and nosocomial sepsis but statistically not significant. Gram positive organisms were 39.36% in which Staphylococcus aureus was the leading microorganism followed by coagulase negative staphylococcus areus. Gram negative organisms were 60.64% amongst them Klebsiella was the most often encountered followed by Pseudomonas. The most common organism Klebsiella was 87.5% and 78.3% resistance to ampicillin and gentamycin respectively. Among gram negative isolates 87.5% and 77.2% were resistance to ampicillin and gentamycin respectively. Among gram positive isolates 58.5% and 31.5% resistance were noted to ampicillin and gentamycin respectively. Resistance to cefotaxim to gram negative and gram positive isolates were 87.34% and 59.35% respectively. Conclusion Klebsiella is most common organism which is almost resistance to first line antibiotics. Resistance to both gram negative and gram positive isolates among firstline antibiotics and even with cefotaxim is emerging and is a major concern in neonatal intensive care unit.

Objectives To study clinical and laboratory profile of patients with eosinophilia and to identify possible causes. Method A prospective and descriptive study was conducted from January 2009- December 2011. All the cases of eosinophilia with symptoms and signs of single or multiple organ were included. The known caused of eosinophilia like allergy, asthma and drugs were excluded. Results During three years period, 84(2.41%) cases had eosinophilia with single or multiple organ involment. 14.3%, 39.3% and 46.4% had mild, moderate and severe eosinophilia respectively, with cases of hypereosinophilia comprising 85.7%. Eosinophilia is seen predominantly in tamang caste with overall age ranging from 1-14 years. Most common symptoms and signs are abdominal pain (67.9%) hepatomegaly (59.5%) respectively. Gastrointestinal system was most commonly involved organ followed by respiratory system. Nineteen percent had polyserositis involving pleural, pericardial effusion and ascites at presentation. Out of 84 patients only nine serum samples were able to be sent for parasitological analysis. sixteen had identifiable and/ or possible causes. Serum sample for parasitological analysis revealed fascilosis, filariasis, strongylosis stercoralis and toxocariasis. Conclusion Eosinophilia is more common among tamang poulation in our study. Most common symptoms and signs are abdominal pain and hepatomegaly respectively. Parasitic infection seems to be the most common cause however further study has to be done to reach final conclusion. KEY WORDS Children, eosinophiliaPublication Comparision of Clinical and Laboratory Parameters in Culture Proven and Unproven Early Onset Sepsis in NICU(Kathmandu University, 2013) Shrestha, S; Dongol Singh, S; Shrestha, NC; Shrestha, RPB; Madhup, SKABSTRACT Backgroud Early onset sepsis remains a major cause for neonatal morbidity and mortality. Objectives The aim of this study was to describe and compare the clinical and laboratory characteristics of neonates in neonatal intensive care unit with culture positive and negative early onset sepsis and verify if there were any differences between the groups. Methods A one year comparative prospective study was conducted from January 2011 to January 2012 in neonatal intensive care unit (NICU), Dhulikhel Hospital, Kathmandu University Hospital (KUH). Results Out of 215 cases of suspected neonatal sepsis, 192 (89.30%) cases of early onset sepsis were admitted in neonatal intensive care unit. Out of which 82 cases (42.7%) had blood culture positive and 110( 57.3%) had culture negative but compatible with features of clinical sepsis. There were no cases of culture proven meningitis and urinary tract infections. The clinical characteristic did not show any statistical differences between the study groups except for seizure which was found to be high in culture positive cases (p= 0.041). The hospital stay in neonatal intensive care unit was significantly longer (p=0.02) in culture positive cases. As for the laboratory test there were no differences found between the two study groups except cases of meningitis was more in culture proven early onset sepsis (p=0.00). The overall mortality in early onset sepsis was 36.95%. The higher mortality of 64.7% was seen in culture positive cases but statistically not significant. Conclusion Clinical manifestation and laboratory test were insufficient to distinguish between neonatal infection with blood culture positive and negative sepsis, hence both culture positive and negative cases should be treated promptly and equally.
