Oral medicine case book 67: Oral manifestations of Evans syndrome: a presenting feature of HIV infection?
A 19 year old female presented with spontaneous intra - oral
bleeding of two days duration. The patient reported that
she was, until recently, in good general health and also that
she had an uncomplicated parturition three years ago. She
recently started noticing blood in her stools and felt increasingly
lethargic. There was no history of trauma or intra-oral
intervention that may have initiated the bleeding.
The clinical examination revealed marked pallor of the facial
skin and multiple small petechiae were seen on both of
her forearms. The intra-oral examination identified marked
halitosis and multiple haemorrhagic lesions with a variable
appearance, being plaque-like on the lip, nodular on the
tongue and fungating and exophytic on the palate and in
the retromolar regions. Even delicate manipulation of the
tissues produced profuse bleeding.DHE

Diffuse duodenal nodular lymphoid hyperplasia: a large cohort of patients etiologically related to Helicobacter pylori infection
Abstract Background Nodular lymphoid hyperplasia of gastrointestinal tract is a rare disorder, often associated with immunodeficiency syndromes. There are no published reports of its association with Helicobacter pylori infection. Methods From March 2005 till February 2010, we prospectively followed all patients with diffuse duodenal nodular lymphoid hyperplasia (DDNLH). Patients underwent esophagogastroduodenoscopy with targeted biopsies, colonoscopy, and small bowel video capsule endoscopy. Duodenal nodular lesions were graded from 0 to 4 based on their size and density. Patients were screened for celiac sprue (IgA endomysial antibody), immunoglobulin abnormalities (immunoglobulin levels & serum protein electrophoresis), small intestine bacterial overgrowth (lactulose hydrogen breath test), and Helicobacter pylori infection (rapid urease test, and histological examination of gastric biopsies). Patients infected with Helicobacter pylori received sequential antibiotic therapy and eradication of infection was evaluated by 14C urea breath test. Follow up duodenoscopies with biopsies were performed to ascertain resolution of nodular lesions. Results Forty patients (Males 23, females 17; mean age ± 1SD 35.6 ± 14.6 years) with DDNLH were studied. Patients presented with epigastric pain, vomiting, and weight loss. Esophagogastroduodenoscopy showed diffuse nodular lesions (size varying from 2 to 5 mm or more) of varying grades (mean score ± 1SD 2.70 ± 0.84) involving postbulbar duodenum. Video capsule endoscopies revealed nodular disease exclusively limited to duodenum. None of the patients had immunoglobulin deficiency or small intestine bacterial overgrowth or positive IgA endomysial antibodies. All patients were infected with Helicobacter pylori infection. Sequential antibiotic therapy eradicated Helicobacter pylori infection in 26 patients. Follow up duodenoscopies in these patients showed significant reduction of duodenal nodular lesions score (2.69 ± 0.79 to 1.50 ± 1.10; p Helicobacter pylori infection showed no significant reduction of nodular lesions score (2.71 ± 0.96 to 2.64 ± 1.15; p = 0.58). Nodules partially regressed in score in 2 patients, showed no interval change in 10 patients and progressed in 2 patients. Conclusions We report on a large cohort of patients with DDNLH, etiologically related to Helicobacter pylori infection.</p
Enrolling adolescents in HIV vaccine trials: reflections on legal complexities from South Africa
<p>Abstract</p> <p>Background</p> <p>South Africa is likely to be the first country in the world to host an adolescent HIV vaccine trial. Adolescents may be enrolled in late 2007. In the development and review of adolescent HIV vaccine trial protocols there are many complexities to consider, and much work to be done if these important trials are to become a reality.</p> <p>Discussion</p> <p>This article sets out essential requirements for the lawful conduct of adolescent research in South Africa including compliance with consent requirements, child protection laws, and processes for the ethical and regulatory approval of research.</p> <p>Summary</p> <p>This article outlines likely complexities for researchers and research ethics committees, including determining that trial interventions meet current risk standards for child research. Explicit recommendations are made for role-players in other jurisdictions who may also be planning such trials. This article concludes with concrete steps for implementing these important trials in South Africa and other jurisdictions, including planning for consent processes; delineating privacy rights; compiling information necessary for ethics committees to assess risks to child participants; training trial site staff to recognize when disclosures trig mandatory reporting response; networking among relevant ethics commitees; and lobbying the National Regulatory Authority for guidance.</p

Gender differences in HIV knowledge and unsafe sexual behaviours among disabled people in South Africa
Purpose: The international literature suggests that disabled people may be at increased risk for HIV infection. There is a growing increasing recognition of this in South Africa, although there remains a paucity of literature on how disabled people are affected by HIV/AIDS. This is a concern given the seriousness of the epidemic here. This paper reports on descriptive data exploring gender differences in HIV knowledge and unsafe sexual behaviours among disabled individuals in South Africa. Method: Data was collected by means of a survey questionnaire from a total sample of 285 disabled individuals in three of the nine provinces in South Africa. Data was analysed by means of descriptive statistics. Results: There are low levels and uncertainty of knowledge about HIV transmission and HIV prevention, with females tending to have lower levels of knowledge than males. Although the importance of condoms in HIV prevention was recognised, there were relatively high levels of reported unsafe sexual behaviours. Males reported higher number of monogamous and concurrent sexual partnerships and sex without a condom after alcohol use. Conclusions: The results support the literature that suggests that disabled people are at risk for HIV infection, and that both male and female individuals with disability are at risk. Implications for Rehabilitation People with disabilities may be at increased risk for HIV infection, yet are often overlooked. Contrary to the myth of asexuality, people with disabilities do have sex. This study indicates lower levels of HIV knowledge among people with disabilities, particularly among women with disabilities. This study also indicates a relatively high prevalence of unsafe sex behaviours among people with disabilities. People with disabilities need to be included in general HIV prevention campaigns.

The first 1000 patients on an internet-based colorectal neoplasia database across private and public medicine in australia: Development of a binational model for the colorectal surgical society of Australia and New Zealand
Background: Collection of multi-institutional data pertaining to the treatment of bowel cancer has been hindered by poor clinician compliance with data entry and the lack of incentive to participate. Objective: This study aimed to establish if a novel browser-based model of data collection results in complete data capture. Design: A Web-based data collection interface was custom written, offering automated reporting modules for clinical outcome to participants and an automated reporting system for outstanding data fields, and summary reporting of surgical quality outcomes. The software was combined with a clinical feedback system incorporating fortnightly data review meetings, at the time of clinical multidisciplinary meetings. Patients And Setting: Selected were 932 consecutive patients with opt-out consent from 3 hospital sites, including public and private medicine. Main Outcome Measures: The primary outcomes measured were the analysis of data completeness and accuracy and ensuring that the highest-quality data were used for clinical audit of the surgical practices of Australian colorectal surgeons for the purpose of quality assurance. Results: A total of 932 men and women, 22 to 94 years of age, treated for colorectal neoplasia were evaluated. We obtained 100% completion (>27,000 data points) of perioperative data registered by 8 specialist colorectal surgeons and a full-time database manager. Conclusions: Data completeness and validity are essential for clinical databases to serve the purpose of quality assurance, benchmarking, and research. The results confirm the safety and efficacy of colorectal cancer surgery in both the public and private sector in Australia. The combination of a simple multiuser interface, defined data points, automated result-reporting modules, and data-deficiency reminder module resulted in 100% data compliance in nearly 1000 clinical episodes. The unprecedented success of this model has lead to the Colorectal Surgical Society of Australia and New Zealand adopting this model for data collection for Australia and New Zealand as the binational database. © The ASCRS 2014
Disabled persons' knowledge of HIV prevention and access to health care prevention services in South Africa
The main research question in this article is how access to information about HIV/AIDS and level of HIV/ AIDS prevention related knowledge are distributed among disabled people, and whether level of knowledge predicts access to HIV/AIDS related services. A survey was carried out among a sample of 285 disabled people from three provinces in South Africa. Analyses of the data revealed that gender and level of education, together with geographical differences, are key predictors for access to information and knowledge about HIV/AIDS among disabled people. For male respondents number of information sources predicts access to voluntary counselling and testing services and HIV testing, while knowledge about prevention predicts access to Voluntary Counselling and Testing centres. Significant gender differences with regards to information, knowledge and access to services highlight the need for gender specific prevention strategies among disabled people. © 2011 Taylor & Francis
