Skin Diseases Among Sub-Saharan African Prisoners: The Cameroonian Profile

Background: Overcrowding and promiscuity observed in our prisons are a spreading source of several diseases including infections transmitted by interhuman contact. It has been argued that skin diseases are the most frequent reasons for consultations in prisons. In Cameroon, no study has been done to assess the magnitude of this issue. Our study aimed at determining the profile of dermatological pathologies among Cameroonian prison inmates. Methods: This was a cross-sectional study at the Mfou Principal Prison from February to April 2014. Were included all prisoners who consulted the research team at the prison infirmary during the period of recruitment and who accepted to take part in the study. Prisoners were consulted and a structured questionnaire was used for data collection. Diagnosis was based on the anamnestic and clinical findings. Participants with uncertain diagnosis were excluded from the study. Data were entered into Microsoft excel 2010 spreadsheets and analyzed using SPSS version 17.0. Results: A total of 217 prisoners were retained for our study out of the 369 present in the prison during the study period. Among these 217 prisoners, 201 (92.6%) were males, 189 (87.1%) were Christians, 123 (56.7%) did not attend the secondary school, and 137 (63.1%) were single. Age ranged from 14 to 60 years with a mean of 32 ± 4.7 years and, age groups 21-30 and 31-40 being the most represented ones. More than half (57.1%) of our population exhibited skin diseases with scabies being present in 41% of cases. The dominating presentations of skin diseases were: scabies (71.8%), eczema (9.7%), dermatophytosis (specifically tinea corporis: 5.6%), pityriasis versicolor (4.8%), and acne (3.2%). Six point five percent of participants presented with more than one skin disease, and eczema was the most frequent disease associated with scabies in 8 cases (6.4%). Pityriasis versicolor was the most common skin disease among females (25% of women infected). Conclusion: There is a high prevalence of skin diseases among prisoners at the Mfou Principal Prison. of which scabies (71.6%), eczema (9.7%), dermatophytosis (5.6%) and pityriasis versicolor (4.8%) were the prevailing skin diseases encountered .There is thereby an urgent need to implement strong and efficient interventions in order to solve the problems of over population, poor hygiene, precarious quality of life and lack of health care in our prisons
