RESUMO
BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is now adjudged the most common liver disease in the world, contributing to the rising incidence of hepatocellular carcinoma worldwide. However, the true prevalence of nonalcoholic fatty liver disease among obese individuals and its contribution to the burden of liver disease in Nigeria is unknown. AIM: To determine the prevalence of nonalcoholic fatty liver disease and associated risk factors in obese subjects. METHODS: This was a cross-sectional analytical study of 280 obese subjects and 280 nonobese age and sex-matched controls seen at our health facility. Data collection was done using an interviewer-administered questionnaire and anthropometric parameters were obtained. Fasting blood samples were collected for blood glucose, lipid profile, and liver biochemistry. Abdominal ultrasound was used to screen for NAFLD. The results were subjected to relevant statistical analysis using SPSS version 20. RESULTS: A higher prevalence of NAFLD was found in obese subjects, compared with nonobese controls (36.4% versus 0.4% P < 0.001). The degree of obesity, transaminases, total cholesterol, diastolic hypertension, fasting blood glucose, and waist circumference was significantly associated with a higher prevalence of NAFLD. However, using multivariate logistic regression analysis, diabetes mellitus and hypertension were significant associations for NAFLD. Individuals with NAFLD had a significantly higher prevalence of metabolic syndrome 65.9%, compared with 34.1% in obese individuals without NAFLD (P < 0.001). CONCLUSION: The prevalence of NAFLD in obese subjects was significant. NAFLD in obese subjects was associated with degree of obesity, hyperlipidemia, hypertension, and diabetes mellitus.

Pyoderma gangrenosum manifests as recurrent deep ulceration of the skin and is associated with a variety of disorders. We report a 40-year-old man who developed ulcers on the flexor surface of his right lower limb following a trauma 10 years prior to the current presentation. He was diagnosed with ulcerative colitis 20 years ago, and was previously placed on sulfasalazine and prednisolone. He also developed an enterocutaneous fistula at the right iliac fossa following an appendectomy he had 16 years previously. Mayo score of his ulcerative colitis was severe (11/12), and he received three courses of intravenous infliximab at irregular intervals as it was difficult to access Infliximab in Nigeria. He was stepped down to tablet Mesalazine after the third course due to cost considerations, and skin grafting was done for the extensive leg ulcer to achieve wound healing after failed steroid and sulfasalazine therapy.
Le pyoderma gangrenosum se manifeste par des ulcères profonds récurrents de la peau et est associé à divers troubles. Nous rapportons le cas d'un homme de 40 ans qui a développé des ulcères sur la face antérieure de sa jambe droite suite à un traumatisme survenu 10 ans avant la présentation actuelle. Il a été diagnostiqué d'une rectocolite hémorragique il y a 20 ans et avait précédemment été traité par sulfasalazine et prednisolone. Il a également développé une fistule entérocutanée à la fosse iliaque droite suite à une appendicectomie subie 16 ans auparavant. Le score de Mayo de sa rectocolite hémorragique était sévère (11/12), et il a reçu trois cures d'infliximab par voie intraveineuse à des intervalles irréguliers en raison de la difficulté d'accès à l'infliximab au Nigeria. Il est passé à la mésalazine en comprimés après la troisième cure en raison de considérations budgétaires, et une greffe de peau a été réalisée pour l'ulcère étendu de la jambe afin d'obtenir une cicatrisation après l'échec du traitement par stéroïdes et sulfasalazine.
