[Diverticular disease: diagnosis and treatment].

Diverticular disease is one of the most common gastroenterological diseases. Its morphological basis are diverticula, whose prevalence in adults nears 50 %, with 25% clinical symptomatology and 5% occurrence of complications. It is a disease of older age, however its incidence is also rising in younger individuals, where it takes a more severe course.

Discrimination between acute and chronic decline of Central European forests using map algebra of the growth condition and forest biomass fuzzy sets: A case study.

Forest decline is either caused by damage or else by vulnerability due to unfavourable growth conditions or due to unnatural silvicultural systems. Here, we assess forest decline in the Czech Republic (Central Europe) using fuzzy functions, fuzzy sets and fuzzy rating of ecosystem properties over a 1×1km grid. The model was divided into fuzzy functions of the abiotic predictors of growth conditions (F including temperature, precipitation, acid deposition, soil data and relative site insolation) and forest biomass receptors (F including remote sensing data, density and volume of aboveground biomass, and surface humus chemical data).

Epithelial markers of colorectal carcinogenesis in ulcerative colitis and primary sclerosing cholangitis.

Aim: To evaluate the expression of epithelial markers of colorectal carcinogenesis in patients with long-term ulcerative colitis (UC) and primary sclerosing cholangitis (PSC) before and after transplantation.

Methods: Eight patients with UC and PSC prior to liver transplantation (PSC-UC), 22 patients with UC after liver transplantation for PSC (OLT), 9 patients with active ulcerative colitis without PSC (UCA), 7 patients with UC in remission (UCR) and 10 controls (N) underwent colonoscopy with multiple biopsies. Specimens were analysed histologically and semi-quantitatively immunohistochemically for p53, Bcl-2 and cyclooxygenase-2 (COX-2) markers.

Polypropylene mesh repair of incisional hernia after kidney transplantation: single-center experience and review of the literature.

Background: Incisional hernia after kidney transplantation increases patient morbidity and impacts quality of life. Reports of hernia mesh repair after kidney transplantation are rare; thus, the benefit of mesh hernioplasty in transplanted patients is assumed. However, it is also assumed that transplant patients are susceptible to incisional and mesh infections.

[Liver transplantation in patients with portal vein thrombosis].

Background: Portal vein thrombosis has (PVT) long been an absolute contraindication to liver transplantation. In patients scheduled for liver transplantation, portal vein thrombosis occurs in 4-15%.

Methods And Results: The authors retrospectively collected data on 740 patients who underwent an initial orthotopic liver transplant at the authors' institution between 1996 and 2009.

[Long-term follow-up of the first 500 liver transplant recipients transplanted at the Institute for Clinical and Experimental Medicine in Prague].

Background: Between April 1995 and November 2005, 500 liver transplantations were performed in 476 patients of age from 3, till 70, at the Transplantation center of the Institute of Clinical and Experimental Medicine (IKEM) in Prague. The most common indications for liver transplantation were alcoholic liver cirrhosis (23%), hepatitis C cirrhosis (17%), and cholestatic cirrhosis (PBC and PSC, 9% each). Mean MELD score of recipients at the transplantation was 15-18 for each year of transplantation.
