Comparing Perceptions with Actual Reports of Close Friend’s HIV Testing Behavior Among Urban Tanzanian Men

Men have lower rates of HIV testing and higher rates of AIDS-related mortality compared to women in sub-Saharan Africa. To assess whether there is an opportunity to increase men’s uptake of testing by correcting misperceptions about testing norms, we compare men’s perceptions of their closest friend’s HIV testing behaviors with the friend’s actual testing self-report using a unique dataset of men sampled within their social networks (n = 59) in Dar es Salaam, Tanzania. We examine the accuracy and bias of perceptions among men who have tested for HIV (n = 391) and compare them to the perceptions among men who never tested (n = 432). We found that testers and non-testers did not differ in the accuracy of their perceptions, though non-testers were strongly biased towards assuming that their closest friends had not tested. Our results lend support to social norms approaches designed to correct the biased misperceptions of non-testers to promote men’s HIV testing.     

Pemphigus vulgaris: a case-based update

Pemphigus vulgaris (PV) is an autoimmune disease accounting for 80% of all cases of pemphigus. Before the advent of corticosteroid therapy, pemphigus was fatal, with a mortality rate of up to 75% in the first year. It is still a serious disorder, but the 5% to 10% mortality rate is now primarily due to the side effects of therapy. In 75% to 80% of cases, PV lesions first appear in the oral cavity. Dentists are therefore in a unique position to recognize the oral manifestations of the disease, allowing early diagnosis and initiation of treatment. The diagnosis is based on pathological examination and immunofluorescence testing. Systemic corticosteriods and steroid-sparing agents are the mainstays of treatment; topical corticosteroids may also be used to accelerate healing of persistent oral lesions. This article describes a 71-year-old woman with multiple chronic ulcers in the oral cavity, in whom PV was diagnosed 4 months after the symptoms first appeared. The article also reviews the current literature on diagnosis and treatment of the condition.     

Leveraging strong social ties among young men in Dar es Salaam: A pilot intervention of microfinance and peer leadership for HIV and gender-based violence prevention

Gender inequality is at the core of the HIV patterns that are evident in sub-Saharan Africa. Gender-based violence (GBV) and lack of economic opportunity are important structural determinants of HIV risk. We piloted a microfinance and health promotion intervention among social networks of primarily young men in Dar es Salaam. Twenty-two individuals participated in the microfinance component and 30 peer leaders were recruited and trained in the peer health leadership component. We collected and analysed observational data from trainings, monitoring data on loan repayment, and reports of peer conversations to assess the feasibility and acceptability of the intervention. Eighteen of the loan recipients (82%) paid back their loans, and of these 15 (83%) received a second, larger loan. Among the loan defaulters, one died, one had chronic health problems, and two disappeared, one of whom was imprisoned for theft. The majority of conversations reported by peer health leaders focused on condoms, sexual partner selection, and HIV testing. Few peer leaders reported conversations about GBV. We demonstrated the feasibility and acceptability of this innovative HIV and GBV prevention intervention. The lessons learned from this pilot have informed the implementation of a cluster-randomised trial of the microfinance and peer health leadership intervention.     

Expandable proximal femoral nails versus 95° dynamic condylar screw-plates for the treatment of reverse oblique intertrochanteric fractures

The treatment of a simple (AO/OTA classification 31A3.1) reverse oblique intertrochanteric hip fracture is a challenge for the orthopaedic surgeon. The surgical options include the use of side plates with various angled leg screws or intramedullary devices. The purpose of this study was to retrospectively assess our results of treating reverse oblique fracture with an expendable proximal femoral nail (EPFN) or with a dynamic condylar screw-plate (DCS: 95°) between January 2006 and July 2009. Thirty-three patients (6 males and 27 females, mean age 78 years) met the study inclusion criteria and comprised the two study groups: 19 had been treated by EPFNs and 14 had received DCSs. They were followed for a mean of 28 months (range 6-47). Eight patients (5 EPFN and 3 DCS) died during the follow-up period from causes not related to the operation. Two ESPN patients and 5 DCS patients had malunions. Functional outcome scores showed better results in the EPFN group, but the difference was statistically significant only for the sitting subcategory (p=0.04). Based on our results and experience, we propose that the EPFN is at least as good as the DCS for treating reverse oblique fractures of the femur.     

Monitoring adverse events following immunization with a new conjugate vaccine against group A meningococcus in Niger, September 2010

Introduction

MenAfriVac is a new conjugate vaccine against Neisseria meningitidis serogroup A, the major cause of meningitis outbreaks in sub-Saharan Africa. In Niger, the MenAfriVac introduction campaign was conducted in the District of Filingue, during September 2010, targeting 392,211 individuals aged 1–29 years. We set up an enhanced spontaneous surveillance system to monitor adverse events following immunization (AEFI) during the campaign period and 42 days thereafter.

Methods

All the 33 health centres of the district have been designated as surveillance units, which reported AEFIs on a daily basis to the health district headquarters. Health care workers were instructed to screen patients presenting with predefined conditions of interest and patients spontaneously presenting at units or at vaccination posts with complaints after vaccination. Cases were classified as serious (resulting in death, hospitalization or long-term disability) or minor. A National Expert Committee was established to determine if serious cases were causally associated with the vaccine.

Results

In total, 356,532 vaccine doses were administered. During 61 days of monitoring, 82 suspected AEFIs were reported: 16 severe and 66 minor. The cumulative incidence was of 23.0 per 100,000 doses. Among severe cases, 14 were classified as coincidences, one urticaria complicated by respiratory distress was classified as a probable vaccine reaction, and one death was unclassifiable because post-mortem information was unavailable. The number of units that reported at least one case was 19/33 (57.6%).

Conclusions

Although these results are limited by underreporting of cases, we did not identify safety concerns with MenAfriVac. The lessons learned from this experience should be used to reinforce the national pharmacovigilance system in Niger to make it complaint with international standards. In order to do so, we recommend using a lighter system for routine; and conducting regular training and supervisory activities to increase its acceptance among local health workers.     

Fertility intent and contraceptive decision-making among HIV positive and negative antenatal clinic attendees in Durban, South Africa

We explored contraceptive decision-making among South African antenatal clinic attendees, fertility intent post-HIV diagnosis, and women's experiences at government health facilities. Data are from in-depth interviews with HIV negative and HIV positive women. We interviewed women in Zulu; interviews were recorded, transcribed, and translated. We conducted qualitative analyses of interviews. Women were the dominant decisionmakers about contraceptive use, whether they involved their partners or not. A majority of women obtained a contraceptive method at a government facility; however, several women were unable to attain sterilizations. Women were presented with limited contraceptive options and were not always able to access services.     

Understanding the diversity of male clients of sex workers in China and the implications for HIV prevention programmes

Male clients of sex workers have been overlooked in China's HIV prevention efforts. This study aims to examine men's practices and attitudes toward extramarital sexual relationships, motivations for visiting female sex workers (FSWs), perceptions of sexually transmitted infection (STI)/HIV risk and risk prevention strategies used. One hundred and eighty-six clients of FSWs with varying socio-economic statuses were interviewed in different sex work settings. Men described no conflict between their role as a client and a responsible family provider. They described social pressure from peers and business partners to visit FSWs, sexual pleasure and companionship as motivators to seek commercial sex. While some men reported no risks associated with visiting FSWs, others identified risks such as being arrested by the police, robbed by gangs and threatening the health of their families by contracting a STI. This study underscores the diversity of FSW clients and the need to understand the beliefs and behaviours of different client types to develop appropriate HIV prevention programmes. It also demonstrates the feasibility of recruiting different types of male clients, a hard-to-reach population for Chinese HIV prevention efforts.     

Ovulation-selective genes: the generation and characterization of an ovulatory-selective cDNA library

Ovulation-selective/specific genes, that is, genes preferentially or exclusively expressed during the ovulatory process, have been the subject of growing interest. We report herein studies on the use of suppression subtractive hybridization (SSH) to construct a 'forward' ovulation-selective/specific cDNA library. In toto, 485 clones were sequenced and analyzed for homology to known genes with the basic local alignment tool (BLAST). Of those, 252 were determined to be nonredundant. Of these 252 nonredundant clones, 98 were analyzed by probing mouse preovulatory and postovulatory ovarian cDNA. Twenty-five clones (26%) failed to show any signal, and 43 cDNAs tested thus far display a true ovulation-selective/specific expression pattern. In this communication, we focus on one such ovulation-selective gene, the fatty acid elongase 1 (FAE-1) homolog, found to be localized to the inner periantral granulosa and to the cumulus granulosa cells of antral follicles. The FAE-1 gene is a beta-ketoacyl-CoA synthase belonging to the fatty acid elongase (ELO) family, which catalyzes the initial step of very long-chain fatty acid synthesis. All in all, the present study accomplished systematic identification of those hormonally regulated genes that are expressed in the ovary in an ovulation-selective/specific manner. These ovulation-selective/specific genes may have significant implications for the understanding of ovarian function in molecular terms and for the development of innovative strategies for both the promotion of fertility and its control.
