Is chronic obstructive pulmonary disease a risk factor for epistaxis after coronary artery bypass graft surgery?

Background: Chronic obstructive pulmonary disease (COPD) has customarily been associated with increased surgical morbidity and mortality rates after coronary artery bypass graft surgery (CABG). The aim of this study was to determine whether there is a relationship between epistaxis and COPD after CABG surgery.

Methods: There were 3 443 patients who consecutively underwent isolated CABG from January 2002 to March 2012.

A measuremental approach to calcaneal fractures.

Objective: The calcaneus is the most frequently broken tarsal bone in the setting of trauma. The diagnosis, treatment and prognosis of calcaneal fractures depend on the location and type determined by the Sanders classification. With the help of measurements on lateral view radiographs like the Böhler's angle, the angle of Gissane, the calcaneal inclination angle and the calcaneal facet height, we can predict the severity of the trauma and prognosis by assessing the collapse of the calcaneus.

The interaction between ghrelin and cannabinoid systems in penicillin-induced epileptiform activity in rats.

The majority of experimental and clinical studies show that ghrelin and cannabinoids are potent inhibitors of epileptic activity in various models of epilepsy. A number of studies have attempted to understand the connection between ghrelin and cannabinoid signalling in the regulation of food intake. Since no data show a functional interaction between ghrelin and cannabinoids in epilepsy, we examined the relationship between these systems via penicillin-induced epileptiform activity in rats.

Normocalcemic hyperparathyroidism and insulin resistance.

Objective: To determine whether insulin resistance (IR) accompanies normocalcemic primary hyperparathyroidism (NCPHP).

Methods: Twenty-five patients with NCPHP and 25 age-, sex-, and body mass index (BMI)-matched controls were included the study. Patients were diagnosed NCPHP if their serum calcium (Ca) concentrations and ionized serum Ca levels were in the normal range but parathyroid hormone (PTH) levels were inappropriately and persistently high.

Materials And Methods: In 50 patients who had liver transplant for treatment of end-stage liver disease from hepatocellular carcinoma and cirrhosis, outcomes were evaluated for associations with locoregional therapy before transplant and Milan criteria.

Postoperative gastrointestinal bleeding after an orthotopic liver transplant: a single-center experience.

Objectives: The overall incidence, causes, and treatment of posttransplant gastrointestinal bleeding, have been previously described. In this study, we examined the causes and treatment of postoperative gastrointestinal bleeding after orthotopic liver transplant.

Materials And Methods: Clinical data of 335 patients who underwent an orthotopic liver transplant at our institution between September 2001 and December 2012 were analyzed retrospectively.

Acute renal injury in liver transplant patients and its effect on patient survival.

Objectives: Acute renal injury is a common complication in liver transplant patients. Acute kidney injury is due to nephrotoxic drugs used after liver transplant, infections, and hemorrhage. Though it is generally reversible, it has effects on grafts and patients survival.

Anesthetic management in pediatric orthotopic liver transplant for fulminant hepatic failure and end-stage liver disease.

Objectives: We assessed the anesthetic management and short-term morbidity and mortality in pediatrics patients who underwent an orthotopic liver transplant for fulminant hepatic failure or end-stage liver disease in a university hospital.

Material And Methods: We retrospectively analyzed the records of children who underwent orthotopic liver transplant from May 2002 to May 2012. Patients were categorized into 2 groups: group fulminant hepatic failure (n=22) and group end-stage liver disease (n=19).

The history of liver transplantation in Turkey.

Liver transplantation is the definitive treatment for end-stage liver diseases. The first successful liver transplant was performed in the United States by Thomas Starzl in 1967. The first successful solid organ transplant in Turkey was a living-related kidney transplant performed by Dr.

Comparison of IMRT and VMAT plans with different energy levels using Monte-Carlo algorithm for prostate cancer.
