Abstract: Self-medication is becoming a common type of self-care behavior among the population of many countries. Many international studies have investigated the prevalence and nature of self-medication practices at the population level. In Nigeria, some workers have also looked at the population prevalence of self-medication in general; however the prevalence of antibiotic self-medication among medical undergraduates has not yet been studied. The interest in studying this practice among this select group is due to the fact that they are the future prescribers and health educators of the population of Nigeria. The study was a cross-sectional pre-tested questionnaire-based study carried out among medical students of the Bayero University, Kano, North-West Nigeria during a two-week period in August 2008. The information from the returned questionnaire were coded, entered and analyzed using SPSS Version 12 statistical software. A total of 183 students filled and returned the questionnaire giving a response rate of 83.2%. Out of these respondents, 120 (65.6%) were males and the mean age of respondents was 23.2 ± 2.5 years (Range 17 to 31). 71 (38.8%) of the medical students admitted to the practice and there was no statistically significant difference among the different levels of medical education (p >0.05). Antibiotics from the penicillin group (ampicillin/cloxacillin, amoxicillin and ampicillin) were the most frequently used. Self-medication with antibiotics is prevalent among medical undergraduates in Northern Nigeria. There is a need for an intervention to address this practice.[...] Read More.

Abstract: Aim of the study was to compare the ability of the all patients refined diagnosis related groups (APR-DRG) with the centre for medicare and medicaid services diagnosis related groups (CMS-DRG) in predicting multidimensional impairment of elderly patients. Cases discharged from 20 geriatric units were grouped by the CMS-DRG and the APR-DRG. A comprehensive geriatric assessment (CGA) was performed using the activities of daily living (ADL), instrumental activities of daily living (IADL), short portable mental status questionnaire (SPMSQ), comorbidity index rating scale (CIRS), mini nutritional assessment (MNA), geriatric depression scale-short form (GDS-SF) and exton smith scale (ESS). Number of drugs at admission (DPA) and length of stay (LOS) were also recorded. CMS-DRG and APR-DRG relative weights (RW) were used for comparisons. 1273 patients were included. With increasing the APR-DRG-RW, a significant increase in the prevalence of impaired patients was found in ADL, IADL, SPMSQ, CIRS, GDS-SF and ESS. The CMS-DRG-RW subgroups showed a significant difference for MNA and GDS-SF. LOS was significantly different for both APR and CMS DRG. The number of CGA domains in which APR showed a more significant trend in disability when compared to CMS DRG demonstrates that the former was a better predictor of multidimensional impairment.[...] Read More.

Abstract: Medical schemes are insurance institutions that cover medical expenses in South Africa. These institutions reimburse their members for actual expenditure on health. The Medical Schemes Act (Act 131 of 1998) defines the business of a medical scheme as the business of undertaking liability in return for a contribution in order to make provision for obtaining any relevant health service. The Council for Medical Schemes (CMS) is an autonomous statutory body created by parliament to regulate the medical schemes industry in South Africa. The CMS handles complaints from members of medical schemes. The objective of the study was to assess factors that impact on the response time to complaints by members of medical schemes. Survival analysis techniques were employed to assess these factors. The regression models controlled for factors such as, medical scheme type, medical scheme size, severity of complaints and effects of the analysts. The model revealed the effect of analysts as a significant factor to response time to complaints. The findings of the study revealed useful results in terms of identifying analysts that take longer to resolve complaints. The study also revealed that the nature of complaints as an important factor to the response time. There is a need for the complaints department to be properly resourced and continuously train staff to ensure effective resolution of complaints in medical schemes.[...] Read More.

Abstract: Travel medicine has emerged as a new field of medicine that involves pre-travel evaluation, contingency planning during travel, and post-travel care. Its implementation showed major discrepancies among different countries. This study aims to assess the health information given to travelers and detect their sources of information. This is a cross sectional analytical observational study of 397 travelers implemented on different travel destinations all over Egypt. It adopts self-administered structured questionnaires according to the International Travel Health Questionnaire (ITHQ) and in-depth interviews with managers in the Ministry of Tourism. The results showed that 17.5% of the international travelers and none of the national travelers heard about the ITHQ; whereas, 58.9% of the international travelers and 26.8% of the national travelers took information about safety measures from different sources. However, there was a lack of travelers’ knowledge about safety measures with no obvious role of travel agencies.[...] Read More.

Abstract: Malaria is under regular and ongoing surveillance, to detect changes in its trends or distribution in order to initiate investigative or control measures in the country. Owing to limited availability of resources and rational use under the program, prevention and control activities against malaria varies in areas with different intensity of malaria transmission. Transmission dynamics, surveillance, mapping of disease burden for malaria in arid ecological setting of Jodhpur, Rajasthan has described in this study. Monthly epidemiological reports of Jodhpur City, district Jodhpur and all its community health centres were obtained from the office, Chief Medical and Health Officer district Jodhpur for the period 2002 to 2006. Secular trend of malaria incidence, transmission dynamics, mapping of disease burden areas and surveillance of malaria was described. The range of annual parasite incidence (API) was from 0.52 to 2.85 in district Jodhpur, with API[...] Read More.

Abstract: Although HIV transmission among Namibian in-school adolescents is mainly heterosexual, previous data on sexual activity are not disaggregated, making it difficult to target interventions. This study conducted a disaggregated analysis of coital activity and explored various factors associated with coital activity among Namibian High School students. A cross-sectional survey was carried out in 18 schools located in six education regions. Data were collected from 829 students through a structured questionnaire. Pearson χ2 analysis was used to determine the distribution of coital activity for students from different regions, rural-urban areas, ethnic groups, and gender. Factors associated with coital activity were established by the use of odds ratios and multivariate logistic regression analysis. Overall, 50.2% of the students never had sex before and 29.2% were sexually active. Pearson χ2 analysis showed that coital activity was significantly high among students in the Caprivi region, urban areas, Lozi, Herero and Damara-Nama ethnic groups, and male gender. Multivariate logistic regression showed that the only significant factors positively associated with coital activity were Herero ethnicity, male gender, testing for HIV, thinking one could not get HIV if they were faithful to a single sexual partner, having a boyfriend of girlfriend, and drinking beer. These disaggregated results will help design targeted HIV/AIDS preventive programmes for High School students in Namibia. This can be done by targeting messages that reduce students’ coital activity by way of altering personal, peer, and social behaviours.[...] Read More.

Abstract: Northwest Nigeria is frequently beset with inadequate water supply. The safety of drinking water to the people in this part of the country has been of major concern as a result of frequently reported incidences of waterborne infections. To ascertain incidences of waterborne infections in this study, patient medical records in several primary health care centres in Sokoto, Shuni and Tambuwal towns in Northwest Nigeria were examined to collect data on incidences of waterborne infections and bio-data of the patients. Simple statistical analysis (Percentage) of collated data was carried out. The records showed that there are high incidences of waterborne infections namely typhoid, cholera, dysentery, diarrhoea and gastroenteritis in the three towns, and that these are more frequent in children below the age of 5 years. Gender distribution of diarrhoea and dysentery cases in 2004 and 2005 showed on average that more female than male residents contracted the infections. The number of cases of waterborne infections in the three towns increased from 10.03% in 2004 to 14.14% in 2005. Diarrhoea, constituting 6.23% in 2004 and 10.04% in 2005 was the most commonly reported cases of waterborne infection in the three towns. Shuni recorded the highest (8.95%) incidences of diarrhoea infection in 2004, followed by Tambuwal (6.23%) and Sokoto had the least (4.81%) while in 2005 Sokoto had the highest (11.99%) followed by Tambuwal (10.23%) and Shuni had the least (7.55%). Pre-study investigations have shown that people in this part of the country lack wholesome drinking water, government should therefore endeavour to make potable water abundant and accessible to its people.[...] Read More.

Abstract: This study was carried out to determine the prevalence of multiple antibiotic-resistant faecal indicator bacteria in streams and wells which serve as major sources of water for inhabitants of Ile-Ife city in Southwestern Nigeria. Water samples from 2 streams and 10 wells situated at different parts of the city were collected over a 6-month period. The total heterotrophic bacteria, faecal coliform and enterococci counts were performed using standard procedures, and the sensitivity of the isolates to antibiotics was tested. The study indicated high faecal indicator concentrations exceeding quality standards for drinking and recreational waters according to World Health Organization (WHO) and United States Environmental Protection Agency (USEPA). All the faecal coliforms and enterococci isolates presented multiple antibiotic resistances. The water sources pose a threat to human health due to the danger of waterborne diseases and potential for the transfer of antibiotic resistance genes to pathogens. Effective public health education aimed at creating awareness of the implications of consumption of contaminated and untreated water is imperative. Antibiotics should only be administered based on physicians’ prescription.[...] Read More.

Abstract: Under-nutrition prevents growth and development in children and is the leading factor to illness and death among children less than five years of age in developing countries. The objective of the study was to determine associations of demographic, cultural and environmental factors with frequency and severity of malnutrition among children less than five years of age in Zambia. We used data from the Zambia multiple indicator cluster survey (MICS) from years of 1999 to 2000. Altogether 6,142 children participated in the survey. The prevalence rates for being "underweight", "stunted" and "wasted" were 17.6, 37.5 and 4.1%, respectively. Compared to children from Western province, those from Luapula, Northern, and North-West provinces were more likely to be underweight. Children from Lusaka, Southern, Copperbelt, Eastern, and Central provinces were less likely to be underweight compared to those from Western province. Other factors associated with children malnutrition included sex, low educational level of householder and mother, poverty, vaccination status and type of toilet. The data acquired in this study may be used in developing interventions to prevent and mitigate children malnutrition. Special attention may have to be given to the provinces where children are more likely to suffer from malnutrition.[...] Read More.
