Le nodule de Sœur Marie-Josèphe est une métastase ombilicale d'une tumeur le plus souvent intra-abdominale. C'est un signe clinique rare dont l'incidence est de 1-3% de toutes les néoplasies abdomino-pelviennes, avec un pronostic péjoratif du fait de son retard diagnostique. Nous rapportons quatre observations d'une métastase cutanée ombilicale révélatrice d'un adénocarcinome dont deux pancréatiques, un gastrique et un d'origine ovarienne. Le but de notre travail est de montrer à travers ces quatre cas cliniques, l'intérêt de l'imagerie (tomodensitométrie, échographie) et de la biopsie dans la démarche diagnostique. A travers ces quatre observations nous insistons aussi sur les difficultés diagnostiques et thérapeutiques que pose cette tumeur dans nos pays à ressources limitées.
Introduction: Management of pheochromocytoma faces different challenges leading to misdiagnosis and therapeutic delay in developing countries. The aim of our study was to evaluate the diagnostic and therapeutic features as well as the evolution of our management strategies in hospital setting in recent years in Dakar. Patients and Method: We carried out a retrospective study over 12 years (January 2005 to June 2017), in 4 hospitals in Dakar. We only included patients with established diagnosis of pheochromocytoma upon clinical, biological, radiological and histological arguments. Results: During this period, 16 observations have been collected and were all about female patients. The mean age at the time of diagnosis was 36.81 years. The clinical signs were dominated by hypertension found for 14 patients. At biological examination, hypersecretion catecholamine was found in 13 patients, high urinary metanephrines in 7 patients, high plasmatic metanephrines in 2 patients and raised urinary Vanyl Mandelic Acid (VMA) in 4 patients. Dosage of chromogranin A showed high level for one patient. Abdominal CT scan allowed making the adrenal origin of tumors precise. One patient presented bilateral pheochromocytoma. Before being treated surgically, all patients had had medical preparation. The surgical treatment by median laparotomy consisted of an enucleation of the tumor in 2 patients, and adrenal resection in 11patients.The evolution after surgery was favorable in 12 patients out of 13. One patient died 2 days after surgery by hemodynamic instability. In 2 patients who presented metastases, multidrug therapy with cyclophosphamide, vincristine and dacarbazine was decided after a multidisciplinary meeting, but they died before treatment. Conclusion: Management of pheochromocytomas in developing countries is obviously improving, but the mortality rate remains high. Early diagnosis and perioperative care are to be targeted for better outcome and prognosis of this rare tumor in our areas.
The prevention of diabetic foot goes through a systematic podiatric assessment of diabetic patients permitting to identify the foot at risk. Then, we realized a study in the Internal Medicine Department at Pikine Teaching Hospital in Dakar with the assessment of foot risk on admitted diabetic patients as our main objective. Methods: It was about a prospective cross-sectional, descriptive and analytic study done on 18 months period. Results: Overall, 142 patients were gathered. The average age was 56.22 years and the sex-ratio was 0.67. 87.2% of the patients were running type 2 diabetes. The capillary blood glucose and glycated hemoglobin were respectively around 3.24 g/L and 9%. High Blood Pressure was found in 62% of cases. The type of footwear most used by our patients was sandals (96.3%). Also, 30.6% of patients walked barefoot. Prior ulceration and/or amputation were noted in 30% of cases. During the foot examination, a lesion was found in 15.5% of patients. Loss of monofilament sensitivity was about 66.7%. The Ankle-Brachial Index (ABI) less than 0.9 was recorded in 34% of patients and at least a quarter of patients were posteriorly tibial pulselessness. The gradation of the foot risk according to the International Working Group of the Diabetic Foot (IWGDF) was established as follow: grade 0 (58%), grade 1 (9.8%), grade 2 (14.3%), grade 3 (17.3%). The presence of neuropathy ]; p = 0.000), plantar keratosis .399]; p = 0.024) and the absence of pulse perception ]; p = 0.000) were significant associated factors of foot injury occurrence on our patients. Conclusion: The prevention of diabetic foot in emerging countries is accessible by a systematic clinical examination of all diabetic feet and the awareness of adapted footwear.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
