The changing role of the primary school teacher in Swaziland in the context of HIV/AIDS: teacher as caretaker and economic provider

Swaziland has the world''s highest HIV prevalence with 26% of adults aged 15–49 years living with HIV. There are approximately 17,000 Swazi children aged 0 to 14 years living with HIV. This qualitative study explored the experiences of Swazi teachers supporting learners living with or affected by HIV/AIDS, with a specific focus on the extent to which teachers are aware of the “Rights of the Child” in their teaching and approaches. Important themes emerged from thematic analysis including the following: teachers provided more than education to learners living with and affected by HIV, including material goods and additional time, in some cases at the expense of other learners. In the era of HIV/AIDS, the teacher has become the emotional caretaker and economic provider in addition to the predictable role of educator in Swaziland. Education curricula in HIV-burdened countries need to modify training programmes and support services available to teachers to accommodate the complex role that teachers play in caring for learners living with and affected by HIV.     

Increased risk of a positive test for antibody to hepatitis B core antigen (anti-HBC) in autologous blood donors

Controversy exists about the suitability of blood from autologous donors for homologous use. We compared the infectious disease test results of 426 autologous donors, designated by donor history as suitable for homologous use, to those of 86,138 volunteer donations collected over the same 5 month period. Although donor characteristics differed, the relative risk of a positive test for anti-HBc in the autologous group was 2.09. When 413 autologous donors were compared to 413 volunteer donors matched for age, sex, and zip code, the relative risk of a positive test for anti-HBc in the autologous group was 3.2. If anti-HBc is a marker for non-A, non-B hepatitis transmissibility, then our autologous group is not as safe as our volunteer donors. We recommend that autologous blood, even when designated by donor history and laboratory screening results as suitable for homologous transfusion, not be used for other than the intended autologous recipient.     

IS CARDIOVASCULAR DISEASE A RISK FACTOR IN THE DEVELOPMENT OF AXONAL POLYNEUROPATHY?

Objectives: To determine if cardiovascular disease may be a risk factor in the development of chronic idiopathic axonal polyneuropathy (CIAP). Methods: In this incidence case-control study, the prevalence of cardiovascular disease and risk factors in 97 patients with CIAP (mean age 67.5 (SD 7.9) years) and the prevalence of neuropathic features in 97 patients with peripheral arterial disease (PAD) (mean age 67.1 (SD 7.3) years) were investigated. The results were compared with those for 96 age and sex matched controls without diagnosed PAD or polyneuropathy (mean age 67.5 (SD 9.1) years). In a randomly chosen subgroup of 23. patients with CIAP, 42 patients with PAD, and 48 controls, an electrodiagnostic investigation was performed. Results: Patients with CIAP more often had manifest cardiovascular disease and cardiovascular risk factors than controls (stroke 18% v 6% of patients, odds ratio (OR) 3.2 (95% confidence interval (0) 1.8 to 5.9); heart disease 29% v 15%, OR 2.4 (95% Cl 1.2 to 4.9); family history of cardiovascular disease 42% v 21%, OR 2.8 (95% Cl (1.5 to 5.2); hypertension 56% v 39%, OR 2.0 (95% Cl 1.1 to I I 3.6); hypercholesterolaemia 46% v 21%, OR 3.3 (95% Cl 1.5 to 7.3); current smoking 38% v 23%, OR 2.1 (95% Cl I. I to 3.9)). The prevalence of cardiovascular disease and cardiovascular risk factors was lower than in patients with PAD. Patients with PAD more often had polyneuropathy than controls (15% v 5%, OR 3.3 (95% Cl 1.1 to 10.0)). There was a trend towards lower nerve conduction velocities and lower amplitudes on electrodiagnostic investigation compared with controls. Conclusion: This study shows that cardiovascular disease and CIAP often coexist, and therefore cardiovascular disease may be a cofactor in the development of CIAP.     

Paraneoplastic Syndrome in Hawai‘i: A Case of Dermatomyositis Associated with Endometrial Cancer

Dermatomyositis as a paraneoplastic consequence of gynecological malignancy has rarely been reported in literature and never been reported in Honolulu. This case report describes a local Honolulu resident who was diagnosed with endometrial adenocarcinoma upon presenting with acute dermatomyositis symptoms.
