Liver collagen proportionate area predicts decompensation in patients with recurrent hepatitis C virus cirrhosis after liver transplantation

2012

Background and Aims:  Current histological scoring systems do not subclassify cirrhosis. Computer-assisted digital image analysis (DIA) of Sirius Red-stained sections measures fibrosis morphologically producing a fibrosis ratio (collagen proportionate area [CPA]). CPA could have prognostic value within a disease stage, such as cirrhosis. The aim of the present study was to evaluate CPA in patients with recurrent hepatitis C virus (HCV) allograft cirrhosis and assess its relationship with hepatic venous pressure gradient (HVPG). Methods:  In 121 consecutively-transplanted HCV patients with HVPG, measured contemporaneously with transjugular liver biopsies, 65 had Ishak stage 5 or 6 disease (4…

The Clinical Course of Portal Hypertension in Liver Cirrhosis

2000

Portal hypertension is caused by liver cirrhosis in almost %% of patients in Europe and in North America. Other causes such as hepato-splenic schistosomiasis, noncirrhotic portal fibrosis and extrahepatic portal vein thrombosis are more common in Asia and South America.

24-hour Ambulatory BP Monitoring and Home BP Measurements in Resistant Hypertension

2013

Out-of-office BP measurements, ambulatory BP monitoring (ABPM), and self-BP measurement play an important role in the evaluation of resistant hypertension. In fact 24 h ABPM has been considered mandatory at the time to evaluate resistant hypertension from the beginning of clinical use. Furthermore, clinical research has expanded the potential role of out-of-office measurements not only to the initial evaluation of resistant hypertension but also to refine cardiovascular and renal risk stratification and for a better follow-up. The widespread use of self-BP measurement at home introduced a new tool to properly assess out-of-office BP, and it has also been recommended in these patients althou…

Intestinal filtration as a consequence of increased mucosal hydraulic permeability

1980

Two mechanisms have been proposed to explain the secretory action of laxative compounds in the intestine: 1. increase of the intracellular amount of cyclic adenosine monophosphate due to stimulation of the adenylate cyclase system and 2. inhibition of intestinal transfer processes, in particular the Na,K-ATPase activated sodium absorption. In a set of in vivo and in vitro experiments in rat colon it could be demonstrated that dihydroxy bile acids (deoxycholate) and diphenolic laxatives (oxyphenisatin) enhance the hydraulic permeability of the mucosal tissue. The permeability changes take place--and there is good experimental evidence--at the zonulae occludentes which bind the epithelial cel…

Administration of Second-Generation Extracorporeal Shock Waves without Waterbath for Fragmentation of Extra- and Intrahepatic Bile Duct Stones

1990

First-generation extracorporeal shock-wave sources disintegrate 97% of kidney stones [1, 2]. Recently, in selected patients gallbladder and common bile duct stones were also treated. The technique available so far, however, requires immersion of the patient’s body in a tank of degassed water. The procedure is therefore inconvenient, time consuming, and relatively expensive. The high pressure of shocks (up to 1000 bar) generated by underwater spark discharge causes pain, and general anesthesia is necessary in most patients [3, 4].

CT Angiography as a Confirmatory Test in Brain Death

2012

Objective: From recent studies, it remains unclear whether CT angiography could be an alternative to other established ancillary tests for the diagnosis of brain death. We examined intracranial contrast enhancement in CT angiography after clinically established brain death and compared the results with EEG and TCD findings.

Hypertension is strongly associated with false-positive bicycle exercise stress echocardiography testing results

2016

Exercise echocardiography is a reliable routine test in patients with known or suspected coronary artery disease. However, in ∼15% of all patients, stress echocardiography leads to false-positive stress echocardiography results. We aimed to investigate the impact of hypertension on stress echocardiographic results.We performed a retrospective study of patients with suspected or known stable coronary artery disease who underwent a bicycle exercise stress echocardiography. Patients with false-positive stress results were compared with those with appropriate results.126 patients with suspected or known coronary artery disease were included in this retrospective study. 23 patients showed false-…

Closed Incision Negative Pressure Therapy Achieves Better Outcome Than Standard Wound Care: Clinical Outcome and Cost-Effectiveness Analysis in Open …

2020

BackgroundSurgical site infections (SSIs) and surgical site occurrences (SSOs) are frequent post-operative complications that are dependent on the presence of different risk factors. The use of closed incision negative pressure therapy (ciNPT) is considered a measure by the WHO guidelines for prevention of SSIs. The prevention of SSOs is an extremely important issue in the ventral hernia repair (VHR) surgical field. SSO onset not only affects the patient's quality of life, but can also cause the onset of life-threatening conditions that may require re-hospitalization, re-intervention and often mesh removal. Such outcome can become extremely costly, contributing to increased health care cost…
