BackgroundSkin disorders are generally considered to be more prevalent in the rural areas of Cameroon. This study was carried out to verify this assumption by describing the spectrum of skin disorders in a rural setting of Cameroon.MethodsWe carried out a community-based clinical skin examination of 400 consenting subjects from 4 villages of Cameroon: Nyamanga (27%), Yebekolo (24%), Mbangassina (23%) and Bilomo (26%).ResultsThe overall prevalence of skin diseases in our sample was 62% {95% CI: 57.2%, 66.8%} (248/400). The commonest skin disorders were: fungal infections (25.4%), parasitic infestations (21.4%), atrophic skin disorders (11.7%), hypertrophic skin disorders (9.7%), disorders of skin appendages {acne} (8.9%), benign neoplasm (6.5%), bacterial skin infections (5.2%), pigmentation disorders (4.8%), and dermatitis/eczema (4.0%). Skin infections and infestations constituted 52.82% of all skin disorders. The overall prevalence of infectious and parasitic infestation was 32.75% {95%CI: 28.17%, 37.59%} (131/400) as against 29.25% {95%CI: 24.83%, 33.98%} (117/400) for non-infectious disorders.Among people with skin infections/parasitic infestations, those with fungal infections and onchocercal skin lesions were the most prevalent, accounting for 48.1% (63/131) and 35.1% (46/131); and an overall prevalence of 15.75% {95%CI: 12.3%, 19.7%} (63/400) and 11.5% {95%CI: 8.5%, 15.0%} (46/400) respectively.There was secondary bacterial infection in 12.1% {95%CI: 8.31%, 16.82%} (30/248) of subjects with skin diseases. Hypertrophic and atrophic disorders of the skin were mainly keloids (9.68%), scarification marks (6.05%) and burn scars (5.65%). Skin diseases like dermatitis and eczema (4.03%), malignant tumours and pigmentation disorders were rare in our sample.The proportion of subjects diagnosed with skin disorders after examination (62.8%) was significantly higher than the proportion of 40.8% that declared having skin diseases (p < 0.0001).ConclusionThe prevalence of skin diseases in the rural Mbam valley is alarming, dominated by easily treatable or preventable skin infections and their magnitude is highly neglected by the community, contrasting with findings in the urban setting. Similar studies are needed in other ecological/demographic settings of the country in order to construct a better understanding of the epidemiology of skin disorders. This would lead to the development of national policies to improve skin care.

BackgroundThe persistent high prevalence of human scabies, especially in low- and middle-income countries prompted us to research the sociodemographic profile of patients suffering from it, and its spreading factors in Cameroon, a resource-poor setting.MethodsWe conducted a cross-sectional survey from October 2011 to September 2012 in three hospitals located in Yaoundé, Cameroon, and enrolled patients diagnosed with human scabies during dermatologists’ consultations who volunteered to take part in the study.ResultsWe included 255 patients of whom 158 (62 %) were male. Age ranged from 0 to 80 years old with a median of 18 (Inter quartile range: 3–29) years. One to eight persons of our patients’ entourage exhibited pruritus (mean = 2.1 ± 1.8). The number of persons per bed/room varied from 1 to 5 (mean = 2.1 ± 0.8). The first dermatologist’s consultation occurred 4 to 720 days after the onset of symptoms (mean = 77.1 ± 63.7). The post-scabies pruritus (10.2 % of cases) was unrelated to the complications observed before correct treatment (all p values > 0.05), mainly impetiginization (7.1 %) and eczematization (5.9 %).ConclusionHuman scabies remains preponderant in our milieu. Populations should be educated on preventive measures in order to avoid this disease, and clinicians’ knowledges must be strengthened for its proper diagnosis and management.

BackgroundTo be acquainted of one’s HIV serological status is an important strategy for the fight against HIV/AIDS, but many patients still miss the appointment to receive their HIV-test result. The aim of this study was to determine the epidemiological and serological profiles of patients not coming back to collect their HIV-test result in a tertiary health care facility in Yaoundé, Cameroon.MethodsWe undertook a retrospective analysis of data of patients who visited the HIV-day care unit of the Yaoundé Central Hospital (Yaoundé, Cameroon) from January to December 2009 in order to be screened for HIV, and who did not come back to retrieve their result.ResultsOf the 3990 patients who visited the unit during the study period, 396 (9.92%) did not come back to collect their HIV-test result, of whom 21% were aged 26–30 years representing the most encountered age group. Females (57.8%) were significantly more present than males (p = 0.023). More than half of these patients (54.9%) visited the unit for a voluntary HIV testing. Two hundred and three patients (51.3%) had a positive HIV-test result, of whom 63.5% were females. The most HIV-infected group was the one coming for a voluntary screening (36.5%). Women not returning to receive their results were more likely to be tested HIV-positive (odds ratio = 1.62, 95% confidence interval: 1.08–2.42; p < 0.05).ConclusionsAlmost 10% of patients screened for HIV infection did not come back to collect their result. More strategies should be implemented to reduce this rate, especially targeting young adults (20–35 years) and women. The delay in delivering patients’ results should be shortened. Concurrently, there is need to increase voluntary HIV-testing in our settings.
