Publication An outbreak of El Tor cholera in Kavre district, Nepal(Kathmandu University, 2005) Tamang, MD; Sharma, N; Makaju, RK; Sarma, AN; Koju, R; Nepali, N; Mishra, SKOutbreak of Cholera still remains major public health problem in most of the developing countries including Nepal. A prospective study was carried out at Dhulikhel Hospital, Kathmandu University Teaching Hospital, Kavrepalanchok during 1st May 2004 to 31st October 2004. A total of 148 stool samples from patients with acute diarrhea were collected and further investigated for Cholera. The study was conducted to establish the causes of the outbreak of acute diarrheal disease, antimicrobial profiles of the stool isolates and parasitic co –infection in Cholera cases. The samples were subjected to standard recommended microbial procedures and confirmation of the isolates was done by seroagglutination using V.cholerae polyvalent O1 and 0139 antisera and monovalent Ogawa and Inaba antisera. Out of the 148 stool samples, 46 cases (31%) were found to be positive for V.cholerae serogroup O1, biotype ElTor, serotype Ogawa. Both sexes were equally affected. Young age group of less than 30 years were mostly affected. Brahmin was the most affected ethnic group. The isolates were sensitive to all the antibiotics tested except co-trimoxazole. Among the laboratory confirmed cholera cases 30% exhibited co-infection with other parasites among which Giardia lamblia and Ascaris lumbricoides were the most common.

Nutritional status is one of the key indicators of health Nutritional status of Nepal is not satisfactory. Especially Protein Energy Malnutrition (PEM) in Nepal is a very common problem in children under five years of age. There are number biochemical parameters which become altered during protein energy malnutrition. Objectives: The objectives of the study are to determine biochemical nutritional indicators among children suffering from PEM and to compare all biochemical parameters with well nourished children and also to determine the factors affecting PEM among children under five years. Materials and methods: The study design was cross sectional, descriptive study with control. Children between ages 6 to 59 months attending outpatient department (OPD) and wards of Kanti Children’s Hospital (KCH), Maharajgunj, Kathmandu, Nepal were purposively selected. The sample size was calculated by using prevalence of malnutrition in Nepalese context and allowable error of 10 %, a total of 120 cases which include 60 PEM cases and 60 controls were selected. They were grouped into two groups based on whether they are above or below the 80% of 50th percentile of weight for height based on growth chart of National Centre of Health Statistics 3 (NCHS), USA. Results: The educational status of parents of children with PEM was found to be significantly less (p<0.05) as compared to their non-PEM counterparts. Occupations of parents whose children were in PEM group include mainly housewives and labourers. Larger proportions of children in our study were born at home and exact birth weights of children were not known. Most of the children are colostrum fed. Most of the children in our study were immunized. Almost equal proportion of children belonged to nuclear family type and joint family type. The mean serum glucose, sodium, potassium, cholesterol, haemoglobin was not significantly different in both groups while mean total protein, albumin, and calcium were significantly (p<0.05) low in PEM group when compared to well nourished children (control). There was significantly (p<0.05) higher incidence of hypoproteinemia, hypoalbuminaemia, and hypocalcaemia, in PEM group when compared to control group. Conclusion: A significant proportion of children with protein energy malnutrition had altered biochemical parameters which were related to food intake and biochemical metabolism mandatory during growth and development of children less than five years of age. There was significantly higher proportion of hypoglycaemia, hypoproteinemia, hypoalbuminaemia, anaemia, hypocholesterolemia and hypocalcaemia in children with PEM when compared to normally nourished children.

Potential infectious risks include the spread of infectious diseases and microbial resistance from health-care establishments into the environment and thereby posing risks of getting infections and antibiotic resistance in the communities. Objectives: The objectives of this study were to assess the bacterial load of healthcare liquid waste generated in central hospitals and to explore the antimicrobial resistance pattern of these bacterial isolates. Materials and methods: A descriptive study was carried out in 10 conveniently selected central hospitals of Nepal during the period of May to December 2008. Effluent specimens from each hospital were subjected to total viable count studies by spread plate method in nutrient agar plate and incubated for 24 hours at 370C using standard laboratory protocol. Similarly, all the specimens were cultured in Mac Conkey Agar media supplemented with 30 μg/ml of Chloramphenicol and 20 μg/ml of Gentamycin for the enumeration of multiple drug resistant (MDR) bacteria, which were further subjected to in-vitro antibiotic susceptibility test by modified Kirby Bauer disc diffusion technique for resistance patterns. Results: Total viable counts of hospital effluents significantly exceeded the standard heterotrophic plate count (p=0.000). Similarly, the numbers of multiple drug resistant bacteria were alarmingly high in three (more than 30% in 2 and 50% in 1) hospitals of this study. Drug resistant hospital effluent isolates showed simultaneous resistance for most of the antibiotics including Penicillin, Cephalosporin, Cotrimoxazole, Gentamycin and Quinolones. Conclusion: Healthcare liquid wastes were laden with MDR bacteria and seemed to pose a huge public health threat in the transfer of such resistance to the bacterial pathogens causing community acquired infections, thereby limiting our antibiotic pool.
