RESUMEN
BACKGROUND: Screening for neoplastic lesions is mandatory as a part of the evaluation process of potential candidates for liver transplant (LT). This work aimed at identifying the main findings in screening colonoscopy and their risk factors. METHODS: Endoscopic and pathologic findings of the biopsied lesions of 311 potential candidates for living donor liver transplant were collected and analyzed. RESULTS: Colorectal polyps (8.7%) were the most common colonoscopic finding, of which 4.18% were diagnosed as adenomas. Other findings included hemorrhoids (7.7%), portal hypertensive colopathies (3.5%), angiomatous malformations (2.6%), rectal varices (1.6%), and diverticulosis (1.6%). The univariate analysis revealed that the prevalence of colonic adenoma was significant in patients 50 years and older (P = .03; odds ratio, 1.178; 95% CI, 1.016-1.365) and in patients who had hepatocellular carcinoma (P = .043; odds ratio, 6.5; 95% CI, 1.002-42.172). In the multivariate analysis, age was found to be the single best predictor of the presence of adenoma (P = .044; odds ratio, 1.178; 95% CI, 1.005-1.382). CONCLUSION: We can conclude that a screening colonoscopy prior to liver donor liver transplant should be performed at least in every LT candidate 50 years or older. Colonic polyps were the most common findings on screening colonoscopy prior to LT.

BACKGROUND AND AIM: Behçet's syndrome (BS) is a known cause of Budd-Chiari syndrome (BCS). We aimed at identifying the prevalence of BS in patients with BCS, analyzing different clinical presentations, treatment modalities and outcome of these patients. METHODS: We conducted a retrospective cohort study, in which all medical records of patients who were presented to Tropical Medicine Department, Ain Shams University with a confirmed diagnosis of primary BCS from May 2005 to December 2016 were collected and analyzed. RESULTS: In total, 271 patients had a confirmed diagnosis of primary BCS, included Group I: 232 (85.6%) patients with BCS without BS and Group II: 39 patients (14.4%) with BCS due to BS. Male gender (P=0.000), oral ulcers, genital ulcers, Prominent abdominal veins, lower limb swellings, lower extremity deep venous thrombosis (P=0.000) and jaundice (P=0.003) were more frequent in group II patients. The presence of intrahepatic collaterals (P=0.004) and IVC thrombosis (P=0.000) was significant in group II. Medical treatment alone in the form of immunosuppressive drugs and anticoagulation (66.7% vs. 24.1%)±IVC stenting (23% vs. 1.3%) (P=0.000) were the main treatment modalities for BCS related to BS. The frequency of HCC in BS was significantly higher (10.26% vs. 2.59%) (P=0.013). CONCLUSIONS: The prevalence of BS in Egyptian patients with BCS is considerably high. The clinical presentation of these patients was different from those without BS. Besides, the incidence of HCC was higher in patients with BS, whereas the mortality did not differ between the two groups.

BACKGROUND: Necrolytic acral erythema (NAE) is a distinctive skin lesion that was first described in 1996 with only few cases being reported, mostly from Egypt. It is unique in its acral distribution and exclusive association with hepatitis C virus (HCV) infection. METHODS: Twenty-three patients (mean age 41.7 +/- 11.5 years; M:F 10:13) with clinical features consistent with NAE were enrolled in a 3-year period. Five of those were known HCV-infected individuals and 18 were referred by the dermatologist for evaluation and HCV screening. Liver function tests, serum zinc, hepatitis B markers, HCV antibodies and HCV-RNA were tested. All patients were subjected to skin biopsy examination; five lesional biopsies were selected for electron microscopic examination and capillary endothelium was scanned for hepatitis C viral particles. An additional five patients were subjected to detection of HCV-RNA in their skin biopsies by polymerase chain reaction. All patients received oral zinc sulfate supplementation while interferon-alpha therapy combined with ribavirin was available for four patients. RESULTS: Most NAE patients were adults (91.3%) and the skin lesions were predominantly chronic (78.3%), with affection of the dorsa of toes and/or feet in all cases. Skin biopsies showed hyperkeratosis, psoriasiform epidermis and upper epidermal necrosis. Electron microscope examination demonstrated clumped tonofilaments in the keratinocytes, yet HCV-RNA could not be detected in the skin lesions of examined cases. Interferon-alpha combined with ribavirin caused regression of skin lesions in three patients and complete clearance in one patient. Some improvement was induced by oral zinc administration. CONCLUSION: Necrolytic acral erythema is considered to be a cutaneous marker for HCV infection. The majority of patients are diagnosed by dermatologists. Therefore, improved awareness of this cutaneous lesion should prompt early diagnosis and treatment of HCV, which should in turn cure the lesion and prevent progression of liver disease.
