Spectrum of skin diseases presented at LAUTECH Teaching Hospital, Osogbo, southwest Nigeria

BackgroundPatterns of skin disease in developing nations are changing as frequencies of non-communicable diseases continue to increase. Appraisal of the current status of the disease profile is of utmost importance for health planning and resource allocation. MethodsA prospective analysis of 895 cases of outpatient consultation during the years 2005-2010 was conducted. ResultsThe meanstandard deviation age of patients was 31.1 +/- 19.1years. Non-infectious skin diseases accounted for 80.9% of all cases. Eczemas/dermatitis (27.0%), urticarias/erythemas (11.0%), fungal infections (9.5%), skin appendage disorders (8.9%), papulosquamous diseases (8.2%), pigmentary diseases (8.2%), viral infections (6.8%), and tumors and malignant skin lesions (5.4%) represented the most common presentations. Atopic dermatitis was the most common type of eczema (29.8%) among children (odds ratio [OR] 1.53, 95% confidence interval [CI] 1.09-2.13; P=0.013), in whom cornification disorders (OR 3.90, 95% CI 1.73-8.92; P<0.001) and viral infections (OR 1.80, 95% CI 1.09-3.25; P=0.021) were also frequent. Adults were more likely to be diagnosed with drug eruptions (OR 3.58, 95% CI 1.09-11.80; P=0.003), tumors/malignancy (OR 4.97, 95% CI 1.53-16.10; P=0.030), or autoimmune connective tissue disorders (OR 8.13, 95% CI 1.09-60.20; P=0.015). Female subjects were significantly affected by urticarias (OR 1.53, 95% CI 1.00-2.33; P=0.030) and papulosquamous diseases (OR 1.80, 95% CI 1.09-3.03; P=0.019). ConclusionsThe present pattern shows that non-infectious skin diseases are predominant. Occurrences of eczemas and urticarias are increasing at similar rates, whereas infectious skin diseases are decreasing in frequency. Resources and research should be directed towards the prevention of non-infectious skin diseases at this time as the campaign for a cleaner environment continues.
