Prevalence of oral mucosal lesions in human immunodeficiency virus-infected children attending the Pediatric Infectious Diseases Clinic in Cape Town.

OBJECTIVE: Investigation of the prevalence of oral mucosal lesions in human immunodeficiency virus (HIV)-infected children undergoing highly active antiretroviral therapy (HAART). MATERIALS AND METHODS: Cross-sectional study of 66 HIV seropositive children, comprised of 28 (42.4%) females and 38 (57.6%) males (average age of 6 years). Study participants all required data regarding CD4+ T-helper cell counts and the viral load. All participants underwent an orofacial clinical examination by calibrated clinicians. Associations between the presence of oral mucosal lesions, CD4+ cell counts, and viral load were analyzed using Poisson regression. RESULTS: The prevalence of oral manifestations was detected in 21 children (31.8%). Oral lesions were detected in 16 children with viral load copies <50 cells/mm3 and 22 children with CD4+ counts >500 cells/mm3 . Predominant lesions identified included angular cheilitis (36.7%), candidiasis (13.3%) and atypical oral ulcers (13.3%). The presence of one lesion was the most prevalent represented by 19 children. Oral lesions in relation to the CD4+ counts >500 resulted in; 14 children with one oral lesion, 5 with two lesions and 3 with three oral mucosal lesions. The other half of this CD4+ count patient group presented with no oral mucosal lesions. Oral lesions in relation Viral load copies <50 resulted in; 9 children with one oral lesion, 3 with two oral mucosal lesions and 4 with three oral mucosal lesions. The other half of this Viral load patient group presented with no oral mucosal lesions. No significant correlations were established between the presence of oral mucosal lesions and low CD4+ counts (p = 0.715) nor with high viral load counts (p = 0.638). CONCLUSION: HIV-related oral mucosal lesions still presented in the participants despite management with HAART. Based on the results, CD4+ counts and viral load does not appear to be suitable markers of orofacial involvement in children.

Applying the Haddon matrix conceptual model to guide motor vehicle crash injury research and prevention in Botswana.

INTRODUCTION: Little literature addresses the burden of injury in Botswana, including trauma from motor-vehicle crashes (MVCs). In response, the University of Botswana and the Botswana Ministry of Health and Wellness are collaborating with the University of Pennsylvania to enhance injury and trauma research capacity in Botswana. Here we describe this training program and a research exercise to identify opportunities to prevent, through future research and countermeasures, MVCs specifically in Botswana. METHODS: We initiated a mixed-methods study during a training module during the first two years of the program. The module introduced the Haddon matrix as a conceptual framework, and asked trainees to identify host, vector, and physical/social environment risk factors for MVCs that, if targeted, may lead to primary, secondary, or tertiary prevention. We conducted 10 photovoice elicitation interviews; results were thematically analyzed to further elucidate the context of MVCs in Botswana and potential countermeasures. RESULTS: Our process identified a range of ideas as barriers or facilitators to MVC prevention. The most commonly cited barriers were animals on the road, drunk or reckless driving, poor road quality, lack of road signs/traffic signals to orient drivers, and poor visibility (e.g., no street lighting; poor lighting on vehicles). Regarding primary prevention, participants identified features prior to the crash, across all matrix levels, as influencers of crashes in Botswana. Among these, several human factors (i.e., over-speeding; drunk driving) and environmental factors (i.e., livestock on road) were commonly mentioned as contributors to MVCs, as were cattle gates and traffic calming measures for prevention. CONCLUSION: Results of the Haddon matrix exercise proved useful for training burgeoning Batswana researchers to think conceptually about the occurrence of MVCs in Botswana and think creatively about targeting countermeasures for prevention. The exercise resulted in potential research questions for the trainees to pursue in mentored research of their own.

Oral status of HIV-infected children aged 12 years or younger who attended a Paediatric Infectious Diseases Clinic in Cape Town.

BACKGROUND: Children continue to suffer from the impact of the human immunodeficiency virus-acquired immunodeficiency syndrome (HIV/AIDS) pandemic. In Cape Town, these children receive medical care including antiretroviral therapy from facilities like Tygerberg Hospital's Paediatric Infectious Diseases Clinic. HIV-infected children may experience an increased caries experience when compared with their healthy peers. AIM: The aim of this study was to determine the oral health status of HIV-infected children younger than 12 years receiving antiviral drugs at the Paediatric Infectious Diseases Clinic. DESIGN: A cross-sectional survey was conducted among children aged between 2 and 12 years presenting at this clinic. Caregivers were interviewed to obtain information regarding health seeking behaviour, oral hygiene practices and dietary habits. A single clinician undertook a standardized clinical intraoral examination according to the World Health Organization guidelines, with modifications. RESULTS: Sixty-six children were recruited. A high prevalence of dental caries (78.8%) and an unmet treatment need of 90.4% were recorded among the participants. Most children had never visited the dentist, and those who did had mainly received emergency dental care. CONCLUSION: The high prevalence of severe dental caries in this population highlights the need for oral health awareness and the inclusion of oral health care in the comprehensive care of children with HIV. WHY THIS PAPER IS IMPORTANT TO PAEDIATRIC DENTISTS: The study highlights the importance of collaborating with health professions outside of dentistry. Doctors and nurses are often the first health professionals to come into contact with children with special needs. They should therefore be made aware of the early signs of decay so that these patients can be referred for dental treatment timeously. Holistic management of children with special healthcare needs is essential to improve their overall well-being.
