Comparative radiobiological analysis and preliminary results of Ultra hypofractionated accelerated radiotherapy for low-risk prostate cancer patients.

Purpose: Moderately accelerated hypofractionation (HypoAR) has been recently established as a standard radiotherapy scheme for low-risk prostate cancer. The application of ultra-hypofractionated regimens (ultra-HypoAR), with fraction size above 5 Gy, is also widely tested.

Methods: We applied Image Guided Radiation Therapy (IGRT) ultra-HypoAR delivered with Volumetric Modulated Arc Therapy (VMAT) technique in low-risk prostate cancer patients (5.

Reversible posterior leukoencephalopathy syndrome induced by pazopanib.

Background: The reversible posterior leukoencephalopathy syndrome is a clinical/radiological syndrome characterized by headache, seizures, impaired vision, acute hypertension, and typical magnetic resonance imaging findings. There are several reports in the literature that depict its occurrence in cancer patients. The list of common anticancer and supportive care drugs that predispose to reversible posterior leukoencephalopathy syndrome is expanding and includes not only a large number of chemotherapeutic agents but also an increased number of new targeted drugs, particularly angiogenesis inhibitors such as bevacizumab,sorefenib and sunitinib.

Unusual malpositioning of hemodialysis catheter into the hepatic veins.

Malpositioning of long-term hemodialysis catheter is a known complication that may lead to a gradual decline in blood flow. We report two rare catheter malpositions in the hepatic veins in two patients with end-stage renal disease in whom a dialysis catheter was inserted through the left external jugular vein and the right external jugular vein. Because of gradual reduction of catheters' blood flow, an angiography was performed, which confirmed catheters' tip positioning into the hepatic veins.

Is Post-ERCP Pancreatitis a Genetically Predisposed Complication?

Background/Objectives. Pancreatitis remains the most common complication of ERCP. History of post-ERCP pancreatitis is an independent risk factor for a new episode, suggesting a genetic background.

Complete response after sorafenib therapy for hepatocellular carcinoma in an HIV-HBV co infected patient: Possible synergy with HAART ? A case report.

A significant proportion of HIV patients, ranging between 5-67%, are co-infected with hepatitis B virus (HBV). Several studies suggest an increasing incidence of hepatocellular carcinoma (HCC) in HIV infected individuals. We report the case of a 69 years old male co infected with HBV and HIV who developed HCC.

Percutaneous nephrolithotomy in a patient with intrarenal arterial aneurysm.

We report the case of a male patient with a left renal pelvic stone 2.5 cm in maximum diameter and a large upper pole intrarenal arterial aneurysm on the same side. The stone was treated with percutaneous nephrolithotomy (PCNL).

Endoscopic removal of a toothpick perforating the sigmoid colon and causing chronic abdominal pain: a case report.

Toothpick ingestion is implicated in gut injuries which may cause severe complications, mimicking diseases causing acute abdomen. However, toothpick ingestion-related perforation may also cause mild, non-specific gastrointestinal symptoms without significant findings or major complications. We describe a young male with chronic postprandial lower abdominal pain caused by a toothpick impaction at the rectosigmoid junction after inadvertent ingestion.

Liver regeneration following radiofrequency ablation.

Background: Radiofrequency ablation (RFA) of the liver leads to reduction of liver parenchymal volume. We sought to evaluate the regenerative response of the liver following RFA.

Materials And Methods: Thirty healthy New Zealand white rabbits were subjected to a single session liver RFA using a cool-tip electrode after midline laparotomy.

Reversal of deep vein reflux after successful stenting in a patient with venous hypertension after thigh access graft creation.

Presented here is a case of reversal of deep vein reflux after successful stenting in a patient with venous hypertension and valve incompetence after thigh angioaccess creation. The patient with exhausted upper-extremity access sites underwent a loop graft in the upper thigh. Six months later, the patient developed leg edema and significant femoral vein reflux on duplex ultrasound.

Bone mass, gonadal function and biochemical assessment in young men with trisomy 21.

Objective: The objective of the study was to find out whether biochemical and hormonal profile of sexual function and mineral metabolism are related to low bone mass in young men with Down syndrome.

Study Design: Eleven young men with trisomy 21 (mean age 26.45 years) and 12 healthy university students of similar age, participated in the study.
