BACKGROUND AND AIM In patients with chronic liver disease, the accuracy of ultrasound scan (US), spiral computed tomography (CT), magnetic resonance imaging (MRI), and alpha-fetoprotein (AFP) in diagnosing hepatocellular carcinoma (HCC) has never been systematically assessed, and present systematic review was aimed at this issue. METHODS Pertinent(More)
OBJECTIVE Transient elastography (TE) allows non-invasive evaluation of the severity of liver disease in patients with chronic hepatitis C. This procedure, however, warrants further validation in the setting of liver transplantation (LT), including patients under follow-up for recurrent hepatitis C. SETTING Tertiary referral hospital. PATIENTS 95(More)
BACKGROUND & AIMS The hepatic vein pressure gradient (HVPG) is the standard used to determine the degree of portal hypertension (PH) and an important prognostic factor for patients with cirrhosis; HVPG values correlate with the presence of esophageal varices (EV). However, HVPG can only be accurately determined at specialized centers; noninvasive methods(More)
OBJECTIVE Transient elastography (TE) is gaining popularity as a non-invasive method for predicting liver fibrosis, but intraobserver and interobserver agreement and factors influencing TE reproducibility have not been adequately assessed. This study investigated these aspects. SETTING Tertiary referral liver unit. PATIENTS Over a 4-month period, 200(More)
Transient elastography (TE) is a valuable noninvasive technique of measuring liver stiffness and a reliable tool for predicting hepatic fibrosis in patients with chronic liver disease. The role of TE in patients with beta-thalassemia has not been extensively investigated. The present study aimed to evaluate the role of TE in the assessment of hepatic(More)
BACKGROUND Diabetic macular oedema (DMO) is a thickening of the central retina, or the macula, and is associated with long-term visual loss in people with diabetic retinopathy (DR). Clinically significant macular oedema (CSMO) is the most severe form of DMO. Almost 30 years ago, the Early Treatment Diabetic Retinopathy Study (ETDRS) found that CSMO,(More)
PURPOSE To evaluate the accuracy of ultrasonography (US) in the detection of Crohn disease in adults by systematically reviewing both cohort studies (those including patients whose clinical characteristics were consistent with those caused by an inflammatory bowel disease) and case-control studies (those in which patients with Crohn disease were compared(More)
The purpose of the study was to compare treatment outcomes in patients with breast cancer treated with partial breast irradiation (PBI) and of those treated with whole breast-radiation therapy (WBRT). We conducted a systematic review and meta-analysis of published randomized clinical trials comparing PBI versus WBRT. Primary outcome was overall survival and(More)
BACKGROUND Randomized controlled trials (RCTs) that use the modified intention-to-treat (mITT) approach are increasingly being published. Such trials have a preponderance of post-randomization exclusions, industry sponsorship, and favourable findings, and little is known whether in terms of these items mITT trials are different with respect to trials that(More)
