Human immunodeficiency virus (HIV) infection had been reported to increase serum Immunoglobulin E (IgE) and the prevalence of atopic diseases. However, there is a paucity of data in the literature on the association between the severity of HIV infection and serum IgE and atopic diseases among children in the Sub-Sahara African region, particularly Nigeria. OBJECTIVES: To assess serum IgE levels, prevalence and pattern of atopic diseases, and their association with the severity of HIV infection in children on antiretroviral therapy. METHODS: One hundred HIV-infected children on antiretroviral therapy recruited consecutively into a cross-sectional study were age and sex-matched with 100 non-infected. International study of asthma and allergy in childhood (ISAAC) proforma was used to obtain information from all the participants. Serum IgE levels and Cluster of differentiation (CD) 4+ counts of all the participants were determined, as well as, HIV viral load of the infected participants. HIV viral load, CD 4 counts and WHO clinical staging were used to classified HIV severity. Data analysis was done using statistical package for social sciences (SPSS) version 21, and statistic significant level was put at p

Microscopic structures in the skin are basically the same in all races. Differences are found in histology and physiology of the skin resulting in different skin types, needs and prevailing skin diseases. Skin pigmentation (with the photo-protective properties), and the barrier function of the stratum corneum are the main differences between African and Caucasian skin. The geographic distribution of UV radiation (UVR) has a positive correlation with geographical location. The darker-skinned populations are closer to the equator where there are high amounts of UVR especially in the tropical regions of the world. African skin has the greatest variability in skin color. Africa has both white and dark skinned individuals with the darker-skinned populations being mostly around the equator. Leslie Baumann introduced four parameters that more accurately characterized skin types than previous classification of dry, oily, normal and combination skin. These are dry or oily – D/O; sensitive or resistant – S/R; pigmented or non-pigmented – P/N, and wrinkled or unwrinkled skin – W/T. Combinations of these further produced sixteen skin phenotypes. Dark skinned individuals often have the PT types while the light skinned mostly have the NW types. Skin needs basically depends on the type. Identifying the skin type is fundamental to providing the right skin care. According to Baumann, the fundamental elements of skin care are mild cleansing, hydrating (moisturization with humectants and emollients), replenishing (with lipids, ceramides and fatty acids) and skin protection (UV protection and increased humidity). Skin diseases are associated with skin type. Eczema is more typical in people with DS combinations while acne is associated with OS skin type (especially OSNT and OSPT). Prevalence of skin diseases varies within African communities from 35% to 87% with skin infections affecting 22-46% and eczemas 13-21% of patients in various studies.

Objective: This study set out to assess sex differences and seasonal variations in Pediatric Infectious Diseases (PID) admissions. Methods: One year retrospective study of PID admissions was conducted among children aged one month to 15 years. Relevant information retrieved from patients’ hospital records were dates of admission and discharge, age, sex, final PID diagnoses and outcome. Results:Of 1,035 patients’ records assessed, 603 (58.3%) were males and 432 (41.7%) females (p Conclusion: Male children were more vulnerable to PID, with significant higher malaria incidence among them than females. PID incidence and mortality were significantly higher during the rainy season than dry. Malaria and gastroenteritis occurred significantly in rainy and dry seasons, respectively.

Background: The aim of this prospective study was to determine the prevalence of HCV antibodies among pregnant women and their corresponding offspring in a tertiary medical centre in Southwestern Nigeria. Method: Anti-HCV antibodies (anti-HCV antibodies) were analyzed in blood samples from mothers and cord samples from their corresponding offspring using the Enzyme Linked Immunosorbent Assay (ELISA) method. The results obtained from the study were expressed in simple percentages. Results: Out of the 272 consenting pregnant women screened for anti-HCV antibodies, 25 (9.2%) of them were positive. As none of the pregnant women had multiple births, screening the 272 cord sera from their offspring for the same antibodies revealed that 3 (1.10%) of them were also positive. Thus, the prevalence of anti-HCV antibodies in the pregnant women and their offspring were 9.2% and 1.1% respectively. Conclusion: If vertical transmission of HCV were to be based on the acquisition of anti-HCV antibodies alone, the prevalence of vertical transmission from HCV infected mothers to offspring in the study was 12.0%. Further studies on vertical transmission are suggested to include analysis for HCV-RNA quantification in pregnant mothers and their offspring as well as a long-term follow-up of neonates seropositive for HCV markers. Such studies are necessary to justify any recommendations to be made for the purpose of reducing HCV infection through vertical transmission.

Background: Intestinal parasitoses are common amongst people living in developing countries. They may impact negatively on the growth and health of immune competent children. There is paucity of information on the association between HIV and intestinal parasitoses in African children. Objective: To identify the intestinal infections responsible for infections in HIV infected children and document characteristics of HIV infected children at a Nigerian teaching hospital. Materials and Methods: Consecutive children attending a Paediatric anti-retroviral clinic were studied. Information such as socio-demographics and clinical characteristics elicited from clinical examination were recorded in the proforma. Stool samples of the children were obtained and examined for intestinal parasites. Data was analysed with the SPSS 18 software. Results: A total 52 children were studied and their age ranged between 6 months and 14 years, with a mean of 6.5 years ± 3.93. The 52 were made up of 27 boys and 25 girls, giving a male: female ratio of 1.1:1. 10 (19.2%) of the 52 children were infected with cryptosporidium spp, while 1(1.9%) had Ascaris lumbricoides infestation. Anti-helminthics had previously been administered to 86.5% of children studied. Those who previously received antihelminthics had lower prevalence estimates of cryptosporidium infections. (p
