Purpose: The aim of this study was to analyze the clinical, bacteriological, radiological and therapeutic features of abdominal tuberculosis in a series of 90 patients., Methods: This was a retrospective and descriptive multicentre study of 90 cases of abdominal tuberculosis conducted from June 1997 to June 2008. Diagnosis of tuberculosis was based on bacteriologic evidence in 12 cases, histological evidence in 55 cases and on clinical and radiologic features with favorable outcomes under specific treatment in the 23 remaining cases., Results: Thirty-one patients were male and 59 were female. The mean age of the patients was 41.5 years. Family history of tuberculosis was reported in three cases. Associated risk factors were: diabetes mellitus (five cases), ethylism (one case), post-hepatitis C cirrhosis (one case), systemic lupus erythematosus treated by corticosteroids (one case). Sites of involvement were: peritoneum (78 cases), liver (14 cases), gut (nine cases) and spleen (eight cases). Forty-eight patients (53,3%) had only an abdominal involvement, nine others patients (10%) had an abdominal involvement associated with intra-abdominal lymph nodes, 16 patients (17,8%) had a respiratory involvement (pulmonary, pleural and mediastinal lymph nodes), eight patients (8,8%) presented with an extra-abdominal and extra-respiratory involvement and 10 patients (11,1%) had respiratory and extra-respiratory disease associated with abdominal involvement. Among the 54 patients who underwent laparoscopy or laparotomy, diagnosis was evoked on macroscopic examination in 51., Conclusion: Laparoscopy and laparotomy are still helpful for the diagnosis of abdominal tuberculosis, especially in the presence of peritoneal involvement., (Copyright © 2010 Société nationale française de médecine interne (SNFMI).

Aim: To investigate the etiologies of the upper limb digital necrosis based on a retrospective analysis of 25 cases., Patients and Methods: We retrospectively reviewed the medical records of patients treated for digital necrosis of the upper limb in four departments of internal medicine from January 1997 to December 2003., Results: There were 16 women and nine men, mean age 55 years. Eleven patients were smokers. Raynaud's phenomenon was noted in 12 cases. Connective tissue diseases were the most common cause (nine cases), all of them were women. The second cause was atherosclerosis (five cases) and Buerger's disease (five cases). In the other cases, the following diagnoses were found: vasculitis (three cases) and neoplasm (two cases). No cause could be identified in one female smoker., Conclusion: Digital necrosis is a common symptom, revealing a vascular pathology. Its causes are diverse. In women, it first suggests a connective tissue disease whereas in men, a diffuse arteriopathy. The etiological diagnosis strategy should consider drug intake, anamnesis and Raynaud's phenomenon history. However, in all cases the etiology investigations should not delay the treatment in order to preserve functional prognosis., (Copyright 2009 Elsevier Masson SAS. All rights reserved.)

Purpose: To describe clinical characteristics of Behçet's disease in Tunisia., Methods: It's a retrospective and multicentric study conducted by the Tunisian society of internal medicine. Inclusion criteria were those of the international study group. Were also included patients without international study group criteria but with at least one manifestation among arthritis, venous thrombosis or neurological manifestation with oral and genital ulceration or oral ulceration and skin lesions., Results: Five hundred and nineteen patients were included. 87.5% of them fulfilled the international criteria. The male to female ratio was 2,7. The mean age was 28.7+/-9.3 years at onset and 32.7+/-9.2 years at diagnosis. The incidence of each manifestations was as follows: oral ulcers: 100%, genital ulcers: 87.5%, pseudo-folliculitis: 67.6%, erythema nodosum: 17.5%, positive pathergy test: 51%, joint involvement: 55%, uveitis: 32.2%, vein thrombosis: 24.9%, arterial aneurysms: 3.9%, neurological involvement: 11.6%. The frequency of HLA B51 antigen was 35% among the 187 patients tested. There was no difference in the manifestations of the disease between patients having B51 and those lacking it. Venous thrombosis (29.8 vs 11.4%), arterial involvement (4.4 vs 1.4%) and uveitis (37.5 vs 17,9%) were significantly more frequent in men whereas erythema nodosum (22.9% vs 15.6%) and joint involvement (70,7 vs 49.9%) more frequent in women. The mean follow up was 6,1+/-5.7 years. Mortality rate was 2.3% in our series., Conclusion: Our study confirms the androtropism of the disease in Mediterranean and Middle east countries. Positive pathergy test and venous thrombosis were more frequent in our study, like those from Mediterranean region. Whereas, ocular and neurological involvement were quite less frequent in our series.
