Multi Drug Resistant Pathogens Causing Urinary Tract Infections in Children at Kathmandu Model Hospital.

Introduction: Antibiotic resistance of urinary tract pathogens has increased globally. Updated knowledge of the antibiotic resistance patterns of uropathogens in the health institutes is important for the selection of an appropriate empirical antimicrobial therapy. The aim of this study was to evaluate the multi drug resistant urinary isolates in the children from 1 to15 years and evaluate the options for empiric antibiotic therapy. Materials and Methods: The study was conducted from December 2011 to May 2012 in the Bacteriology laboratory, Kathmandu Model Hospital. Urine samples received in the laboratory were processed for routine, culture and its sensitivity. The antimicrobial susceptibility of bacterial isolates was determined following Clinical and Laboratory Standard Institute (CLSI) recommended Kirby-Bauer Disc Diffusion method. Results: Of the total 372 urine samples received in the laboratory, 60 (16.13%) showed significant growth; of which 55.0 % (33/60) were MDR isolates. Escherichia coli were the predominant isolate from urine sample. Out of 49 Escherichia coli isolates, 27 (45.0%) were Multi drug resistant. Enterococcus faecalis (N=3) was the most predominant Gram positive isolate and 66.67 % (2/3) of this organism were multi drug resistant. Among the first line drugs used against gram negative isolates, nitrofurantoin was the most effective drug followed by quinolones, while among the second line drugs; meropenem was the most effective drug followed by chloramphenicol and amikacin, whereas; nitrofurantoin (100%) was the most effective drug for Gram positive isolates followed by norfloxacin and cefotaxime. Conclusion: High percentages of multi drug resistant uropathogens were revealed in children. Nitrofurantoin was found to be the most effective drug for gram positive, gram negative and multi drug resistant isolates.

A 14-year-old boy with Isolated Tuberculous Orchitis.

The genitourinary tract is the most common extrapulmonary site affected by tuberculosis1. The male genital organs are involved in more than 50% of patients2. The epididymis is the commonest structure to be involved, followed by the seminal vesicles, prostate, testis, and the vas deferens3. An isolated tuberculous orchitis without epididymal involvement is rare. This case report describes extra pulmonary tuberculosis with exclusively testicular presentation. The confirmatory diagnosis of which was made by FNAC of the testis. It provides a successful diagnosis, thereby preventing unnecessary orchidectomy.

Langerhans Cell Histiocytosis - A Case Report.

Histiocytosis is a heterogenous group of disorders that are characterized by proliferation and activation of mononuclear phagocyte system. Langerhans Cell Histiocytosis (LCH) or Class I histiocytosis is a rare disorder of unknown etiology with proliferation of Langerhan cells which may infiltrate a single or multiple organs. This disease is more common in infants and children. It is usually sporadic but a familial pattern is known. The term embraces the whole clinical spectrum of the disorder from single bone lesions (eosinophilic granuloma) to an aggressive widespread multisystem disease in very sick child (Letterer-Siwe disease) with a wide variety of intermediate forms including the Hand-shuller Christian triad. The cause of LCH is not firmly established and most investigators in the field have long suspected that LCH is immunologic disorder either in its etiology or in its pathophysiology1,2. Recent evidence suggests that LCH is a clonal disorder rather than reactive disease3. LCH is classified according to sites of involvement into single system disease and multisystem disease4. Single system disease can be either unifocal or multifocal. Multisystem disease can be either without organ dysfunction or with organ dysfunction. Clinical course of LCH with single system disease is usually benign with high chance of survival5,6. However, its clinical course is often unpredictable and patients can experience spontaneous remission and exacerbations. Histiocytic diseases are currently classified by the writing group of the Histiocyte Society7 in the three classes, namely; Class I: Langerhans Cell Histiocytosis (LCH) Class II: Histiocytosis of mononuclear phagocytes other than Langerhans Cells Class III: Malignant Histiocytic disorders

Intussusception- A Case Report.

Intussusception, the invagination of a portion of the intestine into itself, is one of the emergencies in infancy and childhood. The etiology may be idiopathic or secondary to some pathology within the wall of the bowel. Most cases (90%) are idiopathic1,2 with no identifiable lesion acting as the lead point or pathological apex3 of the intussusceptum Children may present at any age but this occurs most commonly in the first year. The mode of presentation may vary depending upon the time of presentation. A case of intussusception confirmed with the help of an abdominal ultrasound in 10 month old infant who presented with only persistent vomiting but in the absence of classic features is reported with brief review of literature.

An Overview of Neonatal Admissions at College of Medical Sciences (COMS).

Objective: To know the profile of newborn admissions and its outcome and the factors associated with neonatal mortality. Methods: The study included both intramural and extramural cases of 180 newborn babies admitted in nursery over a period of 6 months from 01/08/06 to 31/01/07. The relevant data were recorded on a pre-designed proforma meticulously. Results: There were 180 newborn babies during the study period. The mean birth was 2.7 kg.. Majority, 77.8 %( 140) of the babies weighed equal to or more than 2.5 kg. Low birth weight (LBW) was seen in 22.2 %( 40) babies. There were 80 %( 144) full term babies and 20 %( 36) preterm babies. Majority of the mothers in the age group between 20-30 years had incomplete antenatal check- ups. There were 86 %( 155) normal vaginal deliveries, 4.5 %( 8) forceps deliveries and 9.5 %( 17) caesarean sections. Birth/perinatal asphyxia 39(22%), prematurity 36(20%) and neonatal septicemia 30(17%) comprised of leading admissions. There were 27deaths (15%) in total.13 (7%), 8(5%) and 6(3%) babies died of severe perinatal asphyxia, neonatal septicemia and prematurity respectively. Most of the deaths occurred during the first 72 hours. Conclusions: The mean birth weight is good. The major causes of neonatal death are birth/perinatal asphyxia, prematurity and neonatal septicemia. The factors influencing neonatal mortality are low and poor antenatal care, meconium stained liquor, delay in coming to the hospital, PROM, eclampsia. The study emphasises the importance of regular antenatal care, timely referral of pregnant women with complications to appropriate centers and conducting delivery in a clean environment for lowering neonatal mortality.

A case report of Gilbert Syndrome.

Gilbert syndrome is benign, often familial condition characterized by recurrent but asymptomatic mild unconjugated hyperbilirubinemia in the absence of haemolysis or underlying liver disease. If, it becomes apparent, it is not until adolescence and then usually in association with stress such as intercurrent illness, fasting or strenuous exercise. Virtually all patients have decreased level of UDP-Glucuronosyltransferase, but there also is evidence for a defect in hepatic uptake of bilirubin as well. This case is reported due to its rarity. The prevalence of Gilbert syndrome in U.S is 3-7% of the population.
