The most common problems encountered in the differential diagnosis of hepatocellular lesions are: (a) adenoma vs well-differentiated hepatocellular carcinoma (HCC) in non-cirrhotic liver, (b) focal nodular hyperplasia (FNH) vs adenoma in non-cirrhotic liver, and (c) HCC vs high grade dysplastic nodules and other non-neoplastic nodules in cirrhotic liver. This discussion provides an update of im...

Background The diagnosis of bacterial infection in cirrhotic patients may be difficult, because of the absence of classical signs such as fever and raised white blood cell count. The role of C-reactive protein (CRP) in this context has not been clearly defined. Methods Clinical and laboratory characteristics of 210 consecutive cirrhotic patients with (n=100) or without (n=110) bacterial infec...

Bacterial infection is a common complication in cirrhotic patients. The portal hypertension as well as the immune depression observed in these patients can explain this high incidence of bacterial infection. Because of the high probability of cirrhotic patients to develop infections, antibiotic prophylaxis is warranted in some conditions, such as upper gastrointestinal bleeding or after spontan...

Cirrhotic ascites, in which secondary hyperaldosteronism is a notable feature, is associated with impaired gastric secretion (Baddeley, 1968). Obstruction to hepatic venous outflow, which also induces secondary hyperaldosteronism and ascites (Orloff, Ross, Baddeley, Nutting, Spitz, Sloop, Neesby, and Halasz, 1964), depresses acid secretion from Heidenhain pouches in dogs with cirrhotic and non-...

INTRODUCTION The liver modulates several important roles, such as metabolism and liver cirrhosis, which have several cardiovascular problems. Due to preservative role of antioxidant agents in cardiovascular disease, consequently, many of them are applied as medicinal plants in traditional medicine. Vanillic acid (VA), as an antioxidant agent, has a principal preservative role on some diseases. ...

We investigate the problem of diagnostic lung nodule classification using thoracic Computed Tomography (CT) screening. Unlike traditional studies primarily relying on nodule segmentation for regional analysis, we tackle a more challenging problem on directly modelling raw nodule patches without any prior definition of nodule morphology. We propose a hierarchical learning framework--Multi-scale ...

Relationship between cirrhosis and renal dysfunction is not yet fully understood. A model of cirrhosis with acute hepatic and renal damage (RF), produced by CCl4 in rats, with hemodynamic and renal functional alterations, similar to those observed in decompensated cirrhosis (DC) in man, was used to study chemical nephrotoxicity in animals. We performed in male Wistar rats hepatic and renal func...

OBJECTIVES The aim of this study was to evaluate changes of body composition in cirrhotic patients. Dual energy x-ray absorptiometry (DEXA) and anthropometry were used, and the values obtained were compared. METHODS Mid-arm fat and muscle areas were calculated by anthropometry in 66 cirrhotic patients and 94 healthy controls. In 37 of the cirrhotic patients and 39 of the controls, fat mass, l...

BACKGROUND Portal hypertension is one of the death reasons for the liver cirrhosis patients. The oxidative stress is related to the occurrence and development of portal hypertension in cirrhosis. Malondialdehyde (MDA), one of the lipid peroxides, increases substantially in cirrhotic patients. AIMS To evaluate the relevance between the MDA level and portal hypertension in cirrhotic patients. ...
