AIM Until recently, gastric cancer was the most frequent digestive neoplasia in our country. Our study presents the first synthesis of data regarding mortality rates from digestive cancers, for a period covering 50 years, in Romania. METHODS Age-standardized mortality rates /100,000 population, general and/or per gender, concerning six digestive cancers,(More)
AIMS Non-invasive methods are required to diagnose presence and grading of esophageal varices in patients with hepatic cirrhosis and in this respect we have evaluated the role of transient elastography and abdominal ultrasound parameters. MATERIAL AND METHODS Cirrhotic patients were prospectively evaluated by transient elastography and Doppler ultrasound(More)
PURPOSE The aim of this study was to evaluate whether there is a correlation between peripheral blood expression of angiogenic transcriptional factors/receptors and colorectal cancer (CRC). METHODS Eighty six blood samples collected from patients with CRC (N=42), adenomas and/or hyperplastic polyps(AP, N=30) and individuals without colon pathology(More)
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in Western countries. It affects about 1 billion individuals worldwide. While people with simple steatosis have no higher risk of death than the general population, people with non-alcoholic steatohepatitis are at increased risk of death compared to general(More)
Burkitt's lymphoma is an aggressive B-cell non-Hodgkin lymphoma. It is less common in adults accounting for less than 5% of non-Hodgkin lymphoma cases. Radiological methods (ultrasonography, computed tomography) are indispensable for the initial evaluation and appreciation of organ extension; complete diagnosis is confirmed by the histopathological(More)
Pleural ultrasonography (US) represents nowadays a useful diagnostic tool in the management of pleural diseases. Detection and evaluation of pleural effusions, pneumothorax and pleural-based lesions can be performed with US, which has the advantages of wide availability, low cost, absence of radiation exposure, and portability. It is the best method for(More)
BACKGROUND Steady and persisting falls in gastric cancer (GC) mortality rates have been observed worldwide in the last 50 years, and in Romania too. Colorectal cancer (CRC) is presently the most frequent digestive neoplasia in the Western countries. An increase of CRC incidence and mortality rates has been reported recently in Eastern European countries,(More)
OBJECTIVE To assess the diagnostic value of a particular set of local intensity parameters extracted from ultrasound liver images in conjunction with support vector machine (SVM) classifiers for liver steatosis grading in respect to the "gold standard" provided by liver biopsy. MATERIAL AND METHODS We prospectively enrolled in the study 228 patients with(More)
