Abstract
Background Thousands of medical students undertake international medical electives each year. These students face potentially substantial health and safety risks as well as educational and ethical challenges and therefore should undertake their electives within well-structured and coordinated programs. Methods We conducted a qualitative systematic review based on a pre-determined protocol. Relevant publications and guidelines relating to international medical electives were identified through a review of the literature using on-line search engines, principally PubMed. We then conducted a systematic qualitative synthesis to extract relevant publications. Finally, the literature was organized according to themes, with the aim of developing a structured set of Recommendations for Implementation for program coordinators. Results A wide range of important issues were identified which were categorized into seven themes upon which recommendations were made principally for the benefit of program coordinators: Responsibilities; General policies; Travel advisories; Occupational risk assessment; Funding & finances, Pre-departure training programs; and Post-return debriefing and screening. Conclusions Recommendations for program coordinators on the health and safety of medical students while on international medical electives have been sourced from existing guidelines and relevant publications. There was considerable consensus from the literature and as such these synthesised recommendations could form the basis for internationally accepted standards for elective placement program coordinators.

Abstract
CONTEXT Burkitt lymphoma (BL) is endemic in Uganda and because of the high incidence, diagnosis is often presumed during clinical care and epidemiologic studies. OBJECTIVES To assess the accuracy of the clinical and the local pathology diagnosis of BL as assessed by an outside pathology review diagnosis and to understand the limitations on histopathology practice in a resource-constrained setting at 1 hospital in Uganda. DESIGN Clinically presumed pediatric (<15 years) BL cases with biopsies and pathology reports, from 1993 to 2007, were identified at St Mary's Hospital, Lacor (Gulu, Uganda). Local histopathology procedures, hematoxylin-eosin-stained tissue sections, and formalin-fixed paraffin-embedded blocks were reviewed onsite by an outside pathologist, followed by outside study that included tissue microarray immunohistochemistry and in situ hybridization. RESULTS Local pathology laboratory procedures were inconsistent and suboptimal, especially for tissue fixation. There were 88 clinically presumed BL cases. Sixty-three could be reviewed by outside pathology (25 cases of lost blocks or no remaining tumor) and showed a clinical diagnostic accuracy of 75% (47 confirmed of 63), with a possible range of 62% to 85%, depending on the actual diagnosis of the 25 nonevaluable cases. There were 64 BL cases diagnosed by local pathology. Forty-five could be reviewed by outside pathology (19 cases of lost blocks or no remaining tumor) and showed a local pathology diagnostic accuracy of 82% (37 confirmed of 45), with a possible range of 58% to 88%, depending on the actual diagnosis of the 19 nonevaluable cases. Non-BL diagnoses included other non-Hodgkin lymphomas, Hodgkin lymphoma, and benign infectious lymphadenopathy. CONCLUSIONS Accuracy of clinical diagnosis of BL was reduced by inclusion of other diseases with similar clinical presentations. Local pathology, using morphology alone, only marginally improved clinical accuracy and often could not support outside pathology review due to inadequate laboratory procedures. There is an urgent need to improve pathology services in Uganda before conducting high-quality clinical and epidemiologic studies.

Abstract
Linkage to HIV care and survival in sub-Saharan Africa is not well documented. In 2004 we conducted a randomized trial among medical inpatients in Mulago Hospital to assess the impact of HIV counseling and testing (HCT) on linkage to care and survival. Participants were randomized to inpatient HCT (intervention) or outpatient HCT 1 week post-discharge (control); inpatient HCT was not available at Mulago during the study. Among 590 eligible patients, 85% (500) agreed to participate; 98.8% (248) in the intervention arm received HCT compared to 68.7% (171) in the control arm. Within 6 months, 62.2% (92) of surviving HIV-infected participants received HIV care; 15.0% (20) received antiretroviral medications (ARVs). Overall mortality among HIV-infected participants was 34.6% (72). HCT had significant impact on linkage to care among surviving participants. Referral for HCT was a missed opportunity for diagnosis. There is need for earlier diagnosis and linkage to HIV care among inpatients.

Abstract
Treatment of HIV infection in developing countries, particularly those in Africa, is still a major challenge to healthcare systems with limited laboratory resources. While drug costs have fallen to levels where antiretroviral therapy is now possible in these countries, and results suggest that adherence is as good as in developed countries, questions remain regarding the effect of scarce laboratory resources on treatment monitoring and, hence, outcome. The DART trial aimed to measure the effect of laboratory monitoring. This randomized controlled trial evaluated the differences between routine laboratory monitoring and monitoring driven by clinical events, and was conducted between January 2003 and December 2008 at sites in Uganda and Zimbabwe. The results indicate that clinically driven monitoring is likely to be more cost-effective in this resource-limited situation.

Abstract
BACKGROUND Despite global effort to scale up access to antiretroviral therapy (ART), many people in need of HIV/AIDS care in Uganda have not been reached. HIV testing and ART are not widely offered as routine medical services and data on HIV/AIDS in emergency settings in Sub-Saharan Africa is limited. We determined the HIV prevalence and eligibility for ART in a medical emergency unit at Mulago hospital. METHODS In a cross-sectional study, we interviewed 223 patients who were systematically selected from the patients' register from October through December 2004. HIV testing was offered routinely and results were delivered within 30 minutes. We evaluated HIV infected patients for WHO clinical stage of disease and referred them for HIV/AIDS care. RESULTS Out of 223 patients, 111 (50%) had HIV infection of whom 78 (70%) had WHO clinical stage 3 and 4 of disease thereby requiring ART. Overall, 84 out of 111 (76%) HIV positive patients had not received any specific HIV/AIDS care. CONCLUSION The burden of HIV infection in the medical emergency unit is high and majority of the patients who required ART had no prior HIV/AIDS care. We recommend scale up of HIV/AIDS care in acute care settings in order to increase access to ART.

Abstract
OBJECTIVE Mulago and Mbarara hospitals are large tertiary hospitals in Uganda with a high HIV/AIDS burden. Until recently, HIV testing was available only upon request and payment. From November 2004, routine free HIV testing and counselling has been offered to improve testing coverage and the clinical management of patients. All patients in participating units who had not previously tested HIV-positive were offered HIV testing. Family members of patients seen at the hospitals were also offered testing. METHODS Data collected at the 25 participating wards and clinics between 1 November 2004 and 28 February 2006 were analysed to determine the uptake rate of testing and the HIV seroprevalence among patients and their family members. FINDINGS Of the 51,642 patients offered HIV testing, 50,649 (98%) accepted. In those who had not previously tested HIV-positive, the overall HIV prevalence was 25%, with 81% being tested for the first time. The highest prevalence was found in medical inpatients (35%) and the lowest, in surgical inpatients (12%). The prevalence of HIV was 28% in the 39,037 patients who had never been tested before and 9% in those who had previously tested negative. Of the 10,439 family members offered testing, 9720 (93%) accepted. The prevalence in family members was 20%. Among 1213 couples tested, 224 (19%) had a discordant HIV status. CONCLUSION In two large Ugandan hospitals, routine HIV testing and counselling was highly acceptable and identified many previously undiagnosed HIV infections and HIV-discordant partnerships among patients and their family members.

Abstract
Background Staff shortages could harm the provision and quality of health care in Uganda, so staff retention and motivation are crucial. Understanding the impact of HIV/AIDS on staff contributes to designing appropriate retention and motivation strategies. This research aimed 'to identify the influence of HIV/AIDS on staff working in general hospitals at district level in rural areas and to explore support required and offered to deal with HIV/AIDS in the workplace'. Its results were to inform strategies to mitigate the impact of HIV/AIDS on hospital staff. Methods A cross-sectional study with qualitative and quantitative components was implemented during two weeks in September 2005. Data were collected in two government and two faith-based private not-for-profit hospitals purposively selected in rural districts in Uganda's Central Region. Researchers interviewed 237 people using a structured questionnaire and held four focus group discussions and 44 in-depth interviews. Results HIV/AIDS places both physical and, to some extent, emotional demands on health workers. Eighty-six per cent of respondents reported an increased workload, with 48 per cent regularly working overtime, while 83 per cent feared infection at work, and 36 per cent reported suffering an injury in the previous year. HIV-positive staff remained in hiding, and most staff did not want to get tested as they feared stigmatization. Organizational responses were implemented haphazardly and were limited to providing protective materials and the HIV/AIDS-related services offered to patients. Although most staff felt motivated to work, not being motivated was associated with a lack of daily supervision, a lack of awareness on the availability of HIV/AIDS counselling, using antiretrovirals and working overtime. The specific hospital context influenced staff perceptions and experiences. Conclusion HIV/AIDS is a crucially important contextual factor, impacting on working conditions in various ways. Therefore, organizational responses should be integrated into responses to other problematic working conditions and adapted to the local context. Opportunities already exist, such as better use of supervision, educational sessions and staff meetings. However, exchanges on interventions to improve staff motivation and address HIV/AIDS in the health sector are urgently required, including information on results and details of the context and implementation process.

Abstract
Despite the unprecedented pace of development of drugs for the treatment of a viral disease and the unquestionable efficacy of antiretroviral therapy, there is a need for less toxic and cheaper regimens that could simplify the treatment of HIV infection without sacrificing efficacy. The favorable pharmacokinetic profile and the high genetic barrier of boosted protease inhibitors make them ideal candidates for use as monotherapy. Given the encouraging results of available studies on lopinavir/ritonavir monotherapy in patients with no prior failure with protease inhibitors, it may be warranted to conduct trials to investigate the cost-effectiveness of lopinavir/ritonavir monotherapy as second-line therapy in resource-constrained settings where virologic monitoring is not feasible. In addition, larger trials with longer follow up, with particular attention to the potential consequences of viral replication in sites where the penetration of protease inhibitors may be poor, are needed before this strategy can be considered for routine use.

Abstract
BACKGROUND Home-based antiretroviral therapy (ART) care in Africa has expanded; but social outcomes of home-based ART programs are unknown. METHODS Social experiences of participants in an antiretroviral therapy program involving weekly home visits in Uganda were assessed through interviews at enrollment and after 3 months and analyzed using generalized estimating equations. RESULTS Of 654 participants, 72% were women; median baseline CD4 cell-count was 123 cells/muL. At follow-up, participants were more likely to report community support (adjusted odds ratio [OR] 2.10, 95% confidence interval [CI]: 1.46 to 3.03, P < 0.001), family support (OR 2.65, CI: 2.01 to 3.49, P < 0.001), and relationship strengthening (OR 2.10, CI: 1.46 to 3.03, P = 0.001) than at baseline; 84% attributed these experiences to antiretroviral therapy program participation. There was no change in incidence of negative experiences (P = 0.3). Forty-six percent of women reported a history of partner abuse, but abuse rates 3 months before and after program initiation were low (1% vs. 2%, OR 3.20, CI: 0.94 to 10.9, P = 0.063). Of five women who reported abuse associated with program participation, all had history of domestic violence. Of all participants reporting outcomes associated with antiretroviral therapy program participation at follow-up, 464 (79%) had only positive experiences, 35 (6%) had both positive and negative experiences, and <1% had only negative experiences. CONCLUSIONS Participation in a home-based antiretroviral therapy program was associated with multiple positive social outcomes.

Abstract
PURPOSE OF REVIEW Following our review of AIDS-associated cancer in developing nations in 2004, we sought to update recent publications and review data on the challenges and opportunities for the treatment and research of AIDS malignancies in Africa. RECENT FINDINGS It is apparent that the burden of AIDS-related malignancies and other virus-associated tumors is significant and increasing in Africa. Several recent studies report findings on conjunctival squamous cell carcinoma and there is a report that Hodgkin's disease, a non-AIDS-defining neoplasm, is increasing in incidence. International collaborative partnerships dedicated to AIDS malignancies in developing countries are feasible and invaluable for clinical strategies to address this aspect of the pandemic. A departure point is the ongoing work of the East Africa - Case Western Reserve University Collaboration in AIDS malignancies. SUMMARY The burden of neoplastic complications of HIV infection and endemic virus-associated tumors are assuming increasing significance in Africa. There is a need to develop nonmyelotoxic therapies and approaches that are hypothesis-driven and pathogenesis-based. The scarcity and shortages in this region demand that our scientific and therapeutic strategies are both suitable and pragmatic for testing in this setting. It is also imperative that African investigators lead us in this important endeavor.

Abstract
Health services in sub-Saharan Africa will be faced with increasing numbers of AIDS patients for many years to come. Where there is good availability of drugs and other resources, the costs of treating HIV/AIDS is likely to be higher than those of treating other types of illness. This will put services under strain and potentially jeopardise health system reform, depending on the vulnerability of the system. Whereas previous research has focussed on inpatients, this paper looks at the impact of HIV/AIDS on outpatient services in a district of South Africa. Through facility visits at various levels of care, data concerning HIV status and the costs of care was collected for all patients presenting over a set period of time. The proportion of patients presenting for HIV-related care ranged from 20.2 to 24.5%. The average costs of treating HIV-positive patients were significantly higher than those for non HIV patients at hospitals, with clinics not experiencing this difference due to the limited service provided. District hospitals spent the greatest proportion of direct patient care resources on treating HIV-related illness. In terms of outpatient care, this data suggests that district hospitals may require the most support in dealing with a rising number of AIDS patients.

Abstract
The population of Gulu District (northern Uganda) has been severely incapacitated by war, epidemics and social disruption. This study is aimed at describing disease patterns and trends in this area through a retrospective analysis of discharge records for 155205 in-patients of Lacor Hospital in the period 1992-2002. The burden of infectious diseases in childhood is overwhelming, with malaria accounting for the steepest increase in admissions. Admissions for war-related injuries and malnutrition fluctuated with the intensity of the war and the severity of famine. Emerging and re-emerging infections, such as HIV/AIDS, tuberculosis and Ebola, accounted for a heavy disease burden; however, there has been a trend for admissions related to HIV/AIDS and tuberculosis to decrease since the implementation of community-based services. Vulnerable groups (infants, children and women) accounted for 79.8% of admissions. Long-term war, population displacement, the collapse of social structures and the breakdown of the health system place people at a much greater risk of persistent, emerging and re-emerging infectious diseases, malnutrition and war-related injuries, shaping the 'disease profile of poverty'. Most of the disease burden results from infectious diseases of childhood, whose occurrence could be dramatically reduced by low-cost and effective preventive and curative interventions.

Abstract
Economics affects everyone and the economic impact of HIV/AIDS will take generations to unfold. Recent macroeconomic predictions have emphasized the concept of human capital, and predicted that much higher costs will be associated with the epidemic than earlier suggestions that economies might simply grow more slowly implied. At a firm or sector level AIDS increases the costs of doing business; impact studies at this level are therefore more important for planning. Impacts at household level are some of the most immediate and devastating, owing to the close relationship between households being affected by HIV/AIDS and subsequent impoverishment. The economic impacts of HIV/AIDS at each level will be modified through prevention and treatment interventions. The potential savings to governments through implementation of a programme to prevent mother-to-child transmission provide some of the most compelling evidence for action. However, health services are suffering under a dual burden of increased demand and reduced capacity to deliver, which contributes to a cycle of poor health and economic decline.
