Unlabelled: The variation of capillary filtration rate (CFR) and ankle edema (AE) were evaluated in three groups of patients with venous hypertension with ambulatory venous pressure > 42 mmHg and in healthy subjects before and after treatment for four weeks with HR (Paroven, Venoruton; 0-(beta-hydroxyethyl)-rutosides), a venoactive drug acting on the microcirculation and on capillary permeability. Group A (30 patients) was treated with HR 500 mg tid; group B (30 patients) was treated with 1 g tid; group C (30 patients) was treated with placebo; group D (10 healthy subjects) was treated with HR 1 g/day in a randomised study. CFR was assessed by venous occlusion plethysmography. Subjective symptoms of venous hypertension were assessed by an analogue scale line considering four symptoms: swelling sensation, restless lower extremity, pain and cramps, and tiredness.
Results: There were no significant differences for sex and age distribution among the groups; no significant differences were found for ambulatory venous pressure and refilling time and parameters of venous hypertension among groups. There was a significant difference between normal subjects and patients. There were no drop-outs and observed intolerance. In group A, there was a significant decrease of CFR (P < 0.01) after treatment. In group B (2 g/day), the decrease was greater than that in group A (P < 0.05). In group C (placebo) there was no significant difference before or after treatment. The variations in analogue score was higher with the higher dosage. The score of group A fell from 7.8 (SD 1.3) to 4 (1). Group B's score fell from 7.9 (2) to 3.1 (1.2). In group C (placebo) there was no change. The decrease in the score in the groups of patients was correlated with the variation in edema and CFR.
Conclusion: HR is effective in venous edema and hypertension. Its effects are dose-related.

Hepatic encephalopathy (HE) is traditionally associated with hepatic parenchymal diseases, such as acute liver failure and cirrhosis. Its prevalence in non-cirrhotic portal hypertension (NCPH) patients, extrahepatic portal vein obstruction (EHPVO), and non-cirrhotic portal fibrosis (NCPF) is less well described. HE in NCPH allows one to study the effect of portosystemic shunting and ammonia without significant hepatic parenchymal injury.

Background: The benefits and risks of extending anticoagulant treatment beyond the first 3 to 6 months in patients with venous thromboembolism (VTE) in clinical practice are not well understood.
Methods: ETNA-VTE Europe is a prospective, noninterventional, post-authorization study in unselected patients with VTE treated with edoxaban in eight European countries for up to 18 months. Recurrent VTE, major bleeding, and all-cause death were the primary study outcomes.

Background: Pediatric nephroblastoma is the most common abdominal malignancy in children. Hyperfibrinogenemia and thrombocytosis are often associated with malignancy and poor prognosis. This study aimed to investigate the relationship between high fibrinogen and platelet levels and the clinicopathologic features as well as overall survival in pediatric nephroblastoma.
