The authors report a case of a pregnant woman with Takayasu's arteritis and Crohn's disease. The course of pregnancy was uneventful. It is suggested that these two inflammatory diseases may be immunologically related. A brief review of the literature confirm that fetal and maternal prognosis are generally excellent. 相似文献

AIM: To study the clinical presentation of Budd-Chiari syndrome(BCS) and identify the aetiologies of this disease in Algeria. METHODS: Patients with BCS, hospitalised in our unit from January 2004 until June 2010 were included and the aetiological factors were assessed. Patients presenting a BCS in the setting of advanced-stage cirrhosis or a liver transplantation were excluded from the study. The diagnosis was established when an obstruction of hepatic venous outflow(thrombosis, stenosis or compression) was demonstrated. We diagnosed myeloproliferative disease(MPD) by bone marrow biopsy and V617 F JAK2 mutation. Anti-phospholipid syndrome(APLS) was detected by the presence of anticardiolipin antibodies, anti-β2 glycoprotein antibodies and Lupus anticoagulant. We also detected paroxysmal nocturnal haemoglobinuria(PNH) by flow cytometry. Celiac disease and Behcet disease were systematically investigated in our patients. Hereditary anticoagulant protein deficiencies were also assessed. We tested our patients for the G20210 A mutation at Beaujon Hospital. Imaging procedures were performed to determine a local cause of BCS, such as a hydatid cyst or a liver tumour.RESULTS: One hundred and fifteen patients were included. Mean follow up: 32.12 mo. Mean age: 34.41 years, M/F = 0.64. Chronic presentation was frequent:63.5%. The revealing symptoms for the BCS were ascites(74.8%) and abdominal pain(42.6%). The most common site of thrombosis was the hepatic veins(72.2%). Involvement of the inferior vena cava alone was observed in 3 patients. According to the radiological investigations, BCS was primary in 94.7% of the cases(n = 109) and secondary in 5.2%(n = 6). An aetiology was identified in 77.4% of the patients(n = 89); it was multifactorial in 27%(n = 31). The predominant aetiology of BCS in our patients was a myeloproliferative disease, observed in 34.6% of cases. APLS was found in 21.7% and celiac disease in 11.4%. Other acquired conditions were: PNH(n = 4), systemic disease(n = 6) and inflammatory bowel disease(n = 5). Anticoagulant protein deficiency was diagnosed in 28% of the patients(n = 18), dominated by protein C deficiency(n = 13). Secondary BCS was caused by a compressing hydatic cyst(n = 5) and hepatocellular carcinoma(n = 1). CONCLUSION: The main aetiologic factor of BCS in Algeria is MPD. The frequency of celiac disease justifies its consideration when BCS is diagnosed in our region. 相似文献

The new phenolic glycosides quercetin 3,4'-di-O-beta-d-glucopyranoside-7-O-alpha-l-rhamnopyranoside (moricandin) (1), beta-d-glucopyranosyl 4-O-beta-d-glucopyranosylcaffeate (2), methyl 3-O-beta-d-glucopyranosyl-5-hydroxycinnamate (3), and beta-d-glucopyranosyl 4-O-beta-d-glucopyranosylbenzoate (4), together with the previously known beta-d-glucopyranosyl 4-hydroxybenzoate (5), methyl 4-O-beta-d-glucopyranosylcaffeate (6), 1-O-caffeoyl-beta-d-glucopyranoside (7), and 2-phenylethyl-beta-d-glucopyranoside (8), were isolated from the flowers of Moricandia arvensis. Their structures were elucidated by extensive spectroscopic analysis and chemical methods. Compounds 1-8 were evaluated for antioxidant activity using DPPH, TEAC, and reducing power assays, where the caffeic acid derivative 7 and the quercetin triglycoside 2 proved to possess the most potent scavenging activity. 相似文献

The fully developed laminar flow of a viscous non-Newtonian fluid in a rough-walled pipe is considered. The fluid rheology is described by the power–law model (covering shear thinning, Newtonian, and shear thickening fluids). The rough surface of the pipe is considered to be fractal, and the surface roughness is measured using surface fractal dimensions. The main focus of this study lies in the theoretical investigation of the influence of the pipe surface roughness on the velocity profile and the Darcy friction factor of an incompressible non-Newtonian fluid. The plotted results demonstrate that shear thinning fluids are the most sensitive to the surface roughness compared with Newtonian and shear thickening fluids. For a particular value of the surface fractal dimension, there exists an intersection point where shear thinning, Newtonian, and shear thickening fluids behave the same way regarding the amplitude of the velocity profile and the friction factor. This approach has a variety of potential applications, for instance fluid dynamics in hydrology, blood flow in the cardiovascular system, and many industrial applications. 相似文献
