Teenage pregnancy, unsafe abortion methods and the high incidence of HIV infections among young people are of great concern to the South African public. Due to the lack of accurate information and understanding, some adolescents are forced to succumb to early motherhood from unplanned pregnancies or opt for back-street abortion with at times fatal results. A qualitative exploratory study was conducted in 2003 to determine the adolescents' perceptions towards factors on the Choice on Termination of Pregnancy (CTOP) and the constraints in accessing TOP services. A purposive sampling technique that enabled experts such as health workers to identify suitable candidates for the investigation was employed. Twenty-four (24) adolescents residing in the predominantly rural area of Nkumpi-Lepelle in the Limpopo Province agreed to participate in the focus group interviews. The major findings indicated that most adolescents were uninformed about CTOP. This is attributed to the lack of coordination among health professionals and educators in the dissemination of information. The overwhelming majority of the respondents expressed discomfort at receiving termination of pregnancy services from the local public clinics and hospitals as they regarded such facilities as youth unfriendly. The adolescents also required provision of pre- and post-counselling services for adolescents who would like to terminate pregnancy. The following hypotheses were formulated for future in-depth studies: If adolescents continue to lack information about CTOP, they will not be able to utilize available services to terminate unplanned and unwanted pregnancies. If CTOP services remain inaccessible to the youth, the problem of backstreet abortion will not be eradicated.

Progessive multifocal leukoencephalopathy (PML) incidence has increased about fivefold due to the AIDS pandemic. The disease has an insidious onset with HIV infection as underlying illness in 85% of cases and may present with any combination of weakness, speech disturbances, limb incoordination, cognitive deficits, and visual impairment. Diagnosis is obtained by MRI with high sensitivity but low specificity revealing T2-hyperintense, small to large, sometimes confluent lesions in the white matter, sparing the subcortical U-fibers. A spinal tap can be used to diagnose PML by JC viral DNA amplification with a sensitivity of 80% and a specificity approximating 100%. Effective therapy is either cessation of immunosuppressive therapy in cancer patients or successful restoration of the immune system in HIV infection.

Gamma hydroxybutyrate (GHB) is a psychoactive substance with complex neurophysiological activity and significant potential for abuse, addiction, and dangerous toxicity. In this study, a semistructured interview was administered to 17 subjects to investigate GHB use, including: manner of use; setting; positive and negative consequences; other drug history; and sexual practices. Respondents were overwhelmingly male, but otherwise had a broad demographic background. Settings varied from nightclubs to private use at home. There was significant variability in the drug obtained, which subjects found problematic because of the narrow therapeutic window and ease of accidental overdose. Common positive experiences included increased sexual desire, decreased sexual inhibitions, and decreased anxiety. Common negative consequences included oversedation, loss of consciousness, motor incoordination, and mental confusion. Nine subjects reported that they would use GHB again, some despite severe negative consequences. Although most subjects reported negative experiences, only three felt their use was problematic, and none sought treatment for GHB abuse or addiction. Subjects were highly drug-experienced, most commonly using MDMA, ketamine, cocaine, alcohol, and methamphetamine. Some reported that GHB could cause poor decision making in sexual situations. This effect has significant ramifications for issues such as date rape and control of sexually transmitted diseases, such as HIV.

This paper examines ethical dilemmas in providing care for people with HIV/AIDS. Healthcare providers in this sector are overworked, particularly in the high prevalence states. They are faced with the dual burden of the physical and the emotional risks of providing this care. The emotional risks result from their inability to control their work environment, while having to deal with the social and cultural dimensions of patients' experiences. The physical risk is addressed to some extent by post exposure prophylaxis. But the emotional risk is largely left to the individual and there is little by way of institutional responsibility for minimising this. The guidelines for training workers in care and support programmes do not include any detailed institutional mechanisms for reducing workplace stress. This aspect of the programme needs to be examined for its ethical justification. The omission of institutional mechanisms to reduce the emotional risks experienced by healthcare providers in the HIV/AIDS sector could be a function of lack of coordination across different stakeholders in programme development. This can be addressed in further formulations of the programme. Whatever the reasons may be for overlooking these needs, the ethics of this choice need to be carefully reviewed.

Despite antiretroviral therapy rollout in South Africa, fewer children than expected are accessing HIV care services. Our objectives were to describe barriers and facilitators of uptake of HIV care among children. Our study involved six private-sector clinics which provide HIV care free-of-charge in and around Gauteng province, South Africa. In-depth interviews were conducted in July 2008 with 21 caregivers of HIV-infected children attending these clinics, 21 clinic staff members and three lead members of staff from affiliated care centres. Many children were only tested for HIV after being recurrently unwell. The main facility-related barriers reported were long queues, negative staff attitudes, missed testing opportunities at healthcare facilities and provider difficulties with paediatric counselling and venesection. Caregivers reported lack of money for transport, food and treatments for opportunistic infections, poor access to welfare grants and lack of coordination amongst multiple caregivers. Misperceptions about HIV, maternal guilt and fear of negative repercussions from disclosure were common. Reported facilitators included measures implemented by clinics to help with transport, support from family and day-care centres/orphanages, and seeing children's health improve on treatment. Participants felt that better public knowledge about HIV would facilitate uptake. Poverty and the implications of children's HIV infection for their families underlie many of these factors. Some staff-related and practical issues may be addressed by improved training and simple measures employed at clinics. However, changing caregiver attitudes may require interventions at both individual and societal levels. Healthcare providers should actively promote HIV testing and care-seeking for children.

The benefits of HIV treatment (Highly Active Antiretroviral Therapy [HAART]) have been less apparent in injecting drug users (IDUs), most probably as a result of poor adherence to treatment. We explored factors related to HIV treatment adherence as reported by 23 IDU-HIV patients and nine health professionals from healthcare services in Alicante and Valencia, Spain. We carried out a qualitative study based on personal interviews. Health professionals reported the lack of coordination among hospital services and difficulties in accessibility to nonspecialized services for IDU-HIV patients as relevant factors for treatment adherence. Their perception of a patient's likelihood of treatment adherence was also considered to influence the decision to prescribe HAART. A better treatment adherence was reported by those IDU-HIV patients with a good doctor-patient relationship and by women with family responsibilities. Patients considered the side effects of HIV treatment, the lack of social support, and the active use of recreational drugs as relevant factors to explain incompliance. Interventions and training of health providers should be aimed at the reduction of barriers in patient-provider communication and the overcoming of stereotypes, thus avoiding discriminatory attitudes in treatment in this vulnerable population.

More than 390,000 children are newly infected with HIV each year, only 28 per cent of whom benefit from early infant diagnosis (EID). Rwanda's Ministry of Health identified several major challenges hindering EID scale-up in care of HIV-positive infants. It found poor counseling and follow-up by caregivers of HIV-exposed infants, lack of coordination with maternal and child health-care programs, and long delays between the collection of samples and return of results to the health facility and caregiver. By increasing geographic access, integrating EID with vaccination programs, and investing in a robust mobile phone reporting system, Rwanda increased population coverage of EID from approximately 28 to 72.4 per cent (and to 90.3 per cent within the prevention of mother to child transmission program) between 2008 and 2011. Turnaround time from sample collection to receipt of results at the originating health facility was reduced from 144 to 20 days. Rwanda rapidly scaled up and improved its EID program, but challenges persist for linking infected infants to care.

Isolated cerebellar mass lesion is an uncommon presentation of toxoplasmosis. The authors report one rare case in a 50-year-old HIV-infected male patient who presented with clipped speech, gait ataxia and incoordination. The cerebellar toxoplasmosis was suspected based on imaging findings, despite the atypical location. This case highlights the need for a high index of clinical suspicion among HIV-infected patients with neurological manifestations and suspicious neuroimaging findings.

The development of topically applied products capable of preventing vaginal and rectal transmission of HIV-1 has been on-going for nearly 20 years. Despite this, only one clinical trial has demonstrated protection against sexual transmission of HIV-1 in women. This review covers the development of microbicides, also referred to as topical pre-exposure prophylaxis (PrEP), through three stages. The first stage focused on nonspecific agents, including surfactants such as nonoxynol-9 (N-9), to prevent HIV-1 transmission. Unfortunately, N-9 enhanced susceptibility to sexual transmission of HIV-1 when evaluated for efficacy. Soon thereafter, other nonspecific agents (polyanions) were quickly moved into large efficacy trials. Due to a lack of coordination among investigators and funders, a large investment was made in a class of compounds shown ultimately to be ineffective, although poor adherence may have contributed to these findings. The second stage involved the assessment of the antiretroviral drug tenofovir, formulated as a vaginal gel, which was found to be modestly effective in a Phase IIb trial (CAPRISA-004) when dosed in a coitally-dependent manner. In another Phase IIb trial, VOICE (MTN-003), tenofovir gel was found to be ineffective when dosed once-daily in a coitally-independent manner. Based on pharmacokinetic data, it was concluded the participants were poorly adherent to this dosing regimen, leading to a lack of efficacy. Tenofovir gel is currently in a Phase III safety and efficacy trial in South Africa (FACTS-001), using the coitally-dependent dosing regimen employed in CAPRISA-004. We are now in the third stage of microbicide research. The antiretroviral drug dapivirine is currently in two Phase III safety and efficacy studies formulated as a vaginal ring. It is hoped that the once-monthly dosing regimen will lead to higher adherence than found in the VOICE study. It is now clear that product adherence could be the greatest challenge to demonstrating topical (and to a similar extent oral) PrEP. Novel dosage forms should play a role in creating products that women will use correctly.

The first case of HIV appeared in Pakistan more than 25 years ago, and since then the prevalence of the disease is creeping up apparently at a dawdling pace, with only 3,983, cases registered till November 2010, of which 1,725 are undergoing treatment. The National AIDS Control Program is responsible for managing the epidemic. Pakistan has moved from a 'low prevalence-high risk' to a 'concentrated epidemic' state, yet the forcefulness required for managing this silent escalation of HIV infected numbers is not being highlighted, as it should be. A more holistic focus is the need of the hour, and for this purpose the WHO's Health Systems Building blocks have been used to discuss the state of affairs in Pakistan, with reference to the HIV/AIDS concentrated epidemic. This paper attempts to present a narrative, based on extensive literature review, with a focus on the six building blocks of health, systems strengthening. No doubt, the service delivery has to be responsive; but skilled human resources, a robust information system, an uninterrupted supplies and use of latest technology, adequate financing, and above all good governance at operational level are essential ingredients, which call for re-orienting the national programme today. Lack of coordination, capacity and interventions with questionable sustainability pave a perilous path. Hitherto the issue can be addressed by involving stakeholders from all levels of the society and managing the void between policy and implementation. Furthermore, interventions that focus on the long term future are imperative to combat the menace threatening the human lives.
