This single center prospective cohort study evaluated the influence of hemihepatectomy on glucose homeostasis. The study included 30 patients undergoing hemihepatectomy. All patients underwent an oral 75 g glucose tolerance test before (baseline), 1 week and 1 month after the surgery. Plasma glucose, insulin and glucagon were measured in the OGTT samples,(More)
PEComa is very rare mesenchymal neoplasm which is formed by perivascular epithelioid cells and is characterized by dual melanocytic and myoid differentiation. Up to now only a very few cases of PEComa of the liver have been described worldwide. We herein present a patient who underwent a right hemihepatectomy for a huge tumor which could not be identified(More)
1 Pancreatic hamartomas occur extremely rarely. They may appear as solid masses or cystic forms and should be regarded as malformations rather than neoplasms [1]. Due to absence of characteristic differential features they may be clinically and radiologically mistaken for a malignancy [2]. Misinterpretation of hamartoma as a true neoplasm may result in(More)
BACKGROUND The aim of this study was to assess the disturbances in perfusion of transplanted kidneys (KTx) following an acute occlusion of 1 of the supernumerary renal arteries (SRA). We compared the differences in echogenicity and the size of ischemic areas between routine B mode ultrasonography with Doppler evaluation (US-CD) and contrast-enhanced(More)
BACKGROUND Cyclooxygenase-2 (COX-2) may play a significant role in the development of pancreatic cancer. One of COX-2 main metabolites is prostaglandin E2 (PGE2), which is involved both in inflammation and carcinogenesis. As PGE2 is inactivated in the lungs and the liver we assumed that the best medium to assess the level of PGE2 is not peripheral but(More)
INTRODUCTION Vascular endothelial growth factor (VEGF) is overexpressed in pancreatic cancer. Although VEGF has been shown to be a probable marker for poor prognosis, the VEGF concentration in portal blood has not yet been clinically reported in pancreatic ductal adenocarcinoma (PDAC). The aim of the study was to measure VEGF-A portal blood concentration in(More)
AIM To assess the value of D-dimer level in determining resectability of pancreatic cancer. METHODS Preoperative prediction of pancreatic head cancer resectability remains inaccurate. The use of hemostatic factors may be of potential help, since D-dimers correlate with tumor stage. Single center clinical trial study comprised patients with potentially(More)
BACKGROUND Currently pancreatic cancer is the fourth leading cause of cancer-related death worldwide. Because of its late manifestation and consequent dismal prognosis, there is an urgent need to develop highly sensitive and specific marker. Neutrophil Gelatinase-Associated Lipocalin (NGAL) recently emerged as a protein playing an important role in(More)
BACKGROUND Genetic background of Riedel's thyroiditis remains unknown. Herein, we describe our results of studies on genes expression levels in Riedel's thyroiditis. CASE REPORT AND GENETIC FINDINGS We report the case of 48-year old woman with Riedel's thyroiditis who has presented unusual course of disease with non-specific cervical discomfort, though as(More)
