BackgroundThere is conclusive evidence from observational data and three randomized controlled trials that circumcised men have a significantly lower risk of becoming infected with the human immunodeficiency virus (HIV). The aim of this study was to systematically review economic evaluations on adult male circumcision (AMC) for prevention of heterosexual acquisition of HIV in men.Methods and FindingsStudies were identified from the following bibliographic databases: MEDLINE (Ovid), EMBASE (Ovid), Cochrane Library (Wiley's internet version), NHS EED and DARE Office of Health Economics HEED. The searches were conducted in November 2009. The Drummond 10-point checklist was used for methodological critique of the economic evaluations. Cost data were inflated and converted to 2008 US dollars (US$). Of 264 identified papers, only five met the inclusion criteria and were included in the review. The studies were published between 2006 and 2009. Most of the studies were carried out from the perspective of government healthcare payer. The time horizon ranged from 10 to 20 years. All studies reported that AMC is cost-effective. The reported cost per HIV infection averted ranged from US$174 to US$2808. The key driver of the cost-effectiveness models was circumcision efficacy.ConclusionsAll published economic evaluations offered the same conclusion that AMC is cost-effective and potentially cost-saving for prevention of heterosexual acquisition of HIV in men. On these grounds, AMC may be seen as a promising new form of strategy for prevention of HIV and should be implemented in conjunction with other evidence-based prevention methods.

AMC is found to be cost saving. AMC may be seen as a promising new form of strategy for prevention of heterosexual acquisition of HIV in men, but should never replace other known methods of HIV prevention and should always be considered as part of a comprehensive HIV prevention package.

The majority have good knowledge and positive attitude towards antenatal blood donation. However, there is need to urgently transform this positive attitude to action through continual public enlightenment to reduce maternal morbidity and mortality.

Wood dust becomes a potential health problem when wood particles from processes such as sanding, cutting, drilling, sawing or turning to sap wood becomes airborne. Occupational exposure in sawmills has suggested that workers in sawmills are at risk of developing allergenic disorders, cancers and lung disease. This study assessed the utilization of personal protective equipment among sawmill workers in Ilorin metropolis. Methods: The study was descriptive cross-sectional by design assessing utilization of personal protective devices among sawmill workers in Ilorin metropolis involving 250 sawmill workers that were registered under the Ilorin Plank Sellers' Association. Data was collected using semi-structured, intervieweradministered questionnaires from the participants. The participants were recruited using multistage sampling technique. Data collected from the questionnaire were analyzed using SPSS 16.0 software package. Results: The majority 144 (57.6%) of the respondents own at least one of the personal protective devices while 134 (53.6%) of the respondents utilized at least one of the personal protective devices. Only 54 (21.6%) and 95 (38.0%) of the respondents possess aprons and hand gloves respectively. The least owned PPEs were earmuffs (10.8%) and safety boots (16.8%). Among the 166 respondents who never use PPE, 86 (74.1%) reported inconveniency as the reason for non-utilization of PPE. Conclusion: There is a need to improve the level of knowledge, availability and use of protective devices among the workers through subsequent sensitization and enlightenment on the need to use PPE.

Objective: Good knowledge of safety measures against hazards of lead-acid battery work is important in the control of the work-related health problems. The study assessed the effects of training on knowledge, attitude and practice of safety measures among battery chargers in Ilorin, Nigeria. Methods: The study was a quasi-experimental (non-randomized) study with pretest and post-test design. A total of 107 battery chargers were recruited each for intervention and control group. The study group was offered training on occupational safety measures while the control group did not have training at this stage. Post intervention data was collected 12 weeks after the pre-intervention. Multistage sampling technique was used to select 214 registered battery chargers working in Ilorin in to the study. Data obtained through interviewer-administered questionnaires were analysed using SPSS version 16 software. Results: Less than one-fifth (15.9%) of the study group had good knowledge of hazards relating to battery which increased significantly to more than three-quarters (76.2%) post-intervention. The majority (85.0%) of the study group and (86.0%) of the control group had positive attitude towards safety measures pre-intervention. There was no significant improvement in attitude post intervention. The safety practice of less than one-tenth (6.5%) of the study group was rated good pre-intervention which increased significantly to almost one-fifth (17.8%) post-intervention. There was no significant improvement in the Kwowledge, attidude or practice of safety measures among the control group post intervention. Conclusion: Association of the battery chargers should organize in conjunction with the health institutions training of their members on hazards prevention and safety practices.
