[Venous thromboembolism: What other risk factors in a North African population? A study of 276 cases]. / La maladie veineuse thromboembolique : quels autres facteurs de risque dans une population nord-africaine ? Une étude de 276 cas.

INTRODUCTION: Venous thromboembolism is a multicausal disease. Understanding interactions between risk factors is the key to advance knowledge about the etiology of venous thrombosis. These interactions are still unclear. In addition to traditional risk factors, there is data about many other risk factors, recorded with few populations based prospective epidemiologic studies or punctually reported. Interactions between these risk factors remain unclear. The aim of our work is to identify and analyze combinations of risk factors. METHODS: This is a retrospective, single-center study, which investigates the etiology of venous thromboembolism, on the records of patients hospitalized in internal medicine for venous thrombosis, over a period of 12 years. RESULTS: We selected 276 cases. The average age was 51 years. At least, we found one traditional risk factors in 87 % of cases, 34 patients had no traditional risk factors. Suspected risk factors were found in 81 % of cases and there was at least one punctually reported factor in 34 % of cases. The combination of risk factors mostly found was association of traditional and suspected risk factors. In more than 50 % of patients, we noted at least, more than one traditional or one suspected risk factors. Among 18 patients presenting only suspected risk factors, there was at least combination of 3 risk factors per patient. CONCLUSION: The role of suspected risk factors in the occurrence of venous thrombosis was not negligible in this work. Our data suggest a hypothesis that it's through their association that suspected risk factors might be able becoming comparable to traditional risk factors.

[Takayasu's arteritis associated with acute myeloblastic leukemia]. / Association artérite de Takayasu et leucémie aiguë myéloblastique.

INTRODUCTION: We present one patient with acute myeloblastic leukemia diagnosed two months after the onset of Takayasu's arteritis. EXEGESIS: A 21-year old woman with a previous history of erythema nodosum and episcleritis was admitted for a left cervical mass. Diagnostic imaging showed an aneurism of the left extracranial internal carotid and a stenosis of the left subclavian artery. Histological findings of the carotid aneurism revealed a granulomatous giant cell arteritis consistent with Takayasu's arteritis. Two weeks after, she was discharged, elevated white cell count (440.000/mm3 ) was disclosed. A bone marrow aspirate documented an acute myeloid leukemia. The patient died of intracerebral hemorrhage. CONCLUSION: Leucocytoclastic vasculitis and polyarteritis nodosa occur in acute myeloid leukemia, but the association with Takayasu's arteritis is new. In our knowledge, only two documented cases of Takayasu's arteritis in association with acute myeloblastic leukemia have been published.

[Behçet's disease in Tunisia. Clinical study of 519 cases]. / La maladie de Behçet en Tunisie. Etude clinique de 519 cas.

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.

[Abdominal tuberculosis: a retrospective series of 90 cases]. / Tuberculose abdominale : étude rétrospective de 90 cas.

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.

[McDuffie hypocomplementemic urticarial vasculitis associated with Sjögren's syndrome]. / Vascularite urticarienne hypocomplémentémique de McDuffie associée à un syndrome de Gougerot Sjögren.

We report a patient with Sjögren's syndrome who presented with urticarial hypocomplementemic vasculitis. A 46-year-old female was admitted for assessment of ascitis. Clinical examination and computed tomographic scan disclosed evidence of multiple peripheral and intra abdominal lymph nodes. During her admission, she developed several bouts of acute angioedema and urticarial skin lesions. Minor salivary gland biopsy showed focal sialadenitis, stage IV of Chisholm. Schirmer's test was positive. Laboratory examination found low levels of C1q and high levels of C1q antibodies. Therapy with prednisone and hydroxychloroquine was initiated. Six months later, the patient presented with lower limb oedema. Urinalysis showed proteinuria (1g/day) and renal biopsy revealed membranous nephropathy with favorable outcome with corticosteroids.

[Etiological profile of digital necrosis of the upper limbs: analysis of 25 cases]. / Profil étiologique des nécroses digitales des membres supérieurs : analyse de 25 observations.

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.

[Eosinophilic fasciitis (Shulman's disease): a case series of 11 patients]. / Fasciite avec éosinophilie (syndrome de Shulman): à propos de 11 patients.

PURPOSE: Eosinophilic fasciitis or Shulman's disease is a rare condition of unknown etiology. METHODS: We report a retrospective case series of 11 patients with eosinophilic fasciitis (seven men and four women, including a single pediatric case) and perform a systematic literature review to determine the main features of this disease. RESULTS: Mean age of the patients was 46 years. Subcutaneous induration of limbs observed in all the patients was the major presenting symptom. The induration was atypically located in the chest area in two patients. Blood eosinophilia was absent in five cases. Histological fasciitis was demonstrated in all patients and eosinophilic infiltration was present in seven patients. Relapse of subcutaneous induration was observed in only one patient who gradually developed systemic sclerosis. CONCLUSION: Diagnosis of eosinophilic fasciitis should be considered in the presence myalgia and subcutaneous induration of limbs, blood eosinophilia and hypergammaglobulinemia. Treatment is based on systemic corticosteroids.
