AIM OF THE STUDY: This study aimed to elucidate the possible mechanism(s) of antidiarrhoeal activity of methanol leaf extract of Combretum hypopilinum (MECH) in mice.
MATERIALS AND METHODS: Phytochemical screening and acute toxicity study were conducted according to standard methods. Adult mice were orally (p.o) administered distilled water (10 ml/kg), MECH (1000 mg/kg) and loperamide (5 mg/kg). The probable mechanisms of antidiarrhoeal activity of MECH were investigated following pretreatment with naloxone (2 mg/kg, subcutaneously), prazosin (1 mg/kg, s.c), yohimbine (2 mg/kg, intraperitoneally), propranolol (1 mg/kg, i.p), pilocarpine (1 mg/kg, s.c) and isosorbide dinitrate (150 mg/kg, p.o) 30 min before administration of MECH (1000 mg/kg). The mice were then subjected to castor oil-induced intestinal motility test.
RESULTS: The oral median lethal dose (LD50) of MECH was found to be higher than 5000 mg/kg. There were significant (p
METHODS: Prospective, hospital-based active surveillance for rotavirus was conducted at three public hospitals in two cities during August 2012 - April 2013. Clinical, demographic and estimated cost data were collected from children <5 hospitalized for diarrhea; stool specimens were tested for rotavirus with a commercial enzyme immunoassay. Annual rotavirus hospitalization incidence rate estimates included a conservative estimate based on the number of cases recorded during the nine months and an extrapolation to estimate 12 months incidence rate. National rotavirus disease and economic burden were estimated by extrapolating incidence and cost data to the national population of children aged < 5 years.
RESULTS: A total of 410 children < 5 years of age with diarrhea were enrolled, of whom 239 (58%) tested positive rotavirus, yielding an incidence range of 418-557 rotavirus hospitalizations per 100,000 children < 5 years of age. Most (86%) rotavirus cases were below two years of age with a distinct seasonal peak in winter (December-March) months. The total cost of treatment for each rotavirus patient was estimated at US$ 679 (range: 200-5,423). By extrapolation, we estimated 2,948 rotavirus hospitalizations occur each year in Libyan children < 5 years of age, incurring total costs of US$ 2,001,662 (range: 1,931,726-2,094,005).
CONCLUSIONS: Rotavirus incurs substantial morbidity and economic burden in Libya, highlighting the potential value of vaccination of Libyan children against rotavirus.
METHODS: Qualitative methods involving two focus group discussions and eight in-depth interviews were used to collect the data. The study was conducted at the following places: Tankisinuwari, Kanchanbari and Pokhariya of Morang district, Nepal during the months of February and March 2010. Purposive sampling method was adopted to recruit twenty mothers based on the inclusion criteria. A semi-structured interview guide was used to conduct the interviews. Written informed consent was obtained from all of the participants before conducting the interviews. The interviews were moderated by the main researcher with the support of an expert observer from Nobel Medical College. The interviews were recorded with the permission of the participants and notes were written by a pre trained note-taker. The recordings were transcribed verbatim. All the transcribed data was categorized and analyzed using thematic content analysis.
RESULTS: Twenty mothers participated in the interviews and most (80%) of them were not educated. About 75% of the mothers had a monthly income of up to 5000 Nepalese rupees (US$ 60.92). Although a majority of mothers believed diarrhea to be due to natural causes, there were also beliefs about supernatural origin of diarrhea. Thin watery diarrhea was considered as the most serious. There was diversity in mothers' beliefs about foods/fluids and diarrhea management approaches. Similarly, several barriers were noted regarding diarrhea prevention and/or management such as financial weakness, lack of awareness, absence of education, distance from healthcare facilities and senior family members at home. The elderly compelled the mothers to visit traditional healers.
CONCLUSIONS: There were varied beliefs among the mothers about the types, causes and severity of diarrhea, classification of foods/fluids and beliefs and barriers about preventing or treating diarrhea.
