In the presence of nuisance parameters, we derive an explicit higher order asymptotic formula to compare the expected lengths of conndence intervals given by likelihood ratio statistics arising from the usual proole likelihood and various adjustments thereof. Highest posterior density regions, with approximate frequentist validity, are also included in the study.

Background. Excessive intraoperative bleeding during scoliosis correction extends surgery time, and may increase the risk of complications during surgery and the postoperative period. Recombinant factor VIIa (rVIIa) is widely used to control hemorrhage in patients with hemophilia. Recent reports have examined the use of rVIIa for intraoperative bleeding in patients without coagulopathies. The a...

BACKGROUND Peritoneal carcinomatosis (PC) is associated with a poor prognosis. Cytoreductive surgery (CRS) and HIPEC play an important role in well-selected patients with PC. The aim of the study is to present the differences in the intraoperative parameters in patients who received HIPEC in two different manners, open versus closed abdomen. PATIENTS AND METHODS The population includes 105 pa...

For hypotheses of the type H0 : θ = θ0 vs H1 : θ 6= θ0 we demonstrate the equivalence of a Bayesian hypothesis test using a Bayes factor and the corresponding classical test, for a large class of models, which are detailed in the paper. In particular, we show that the role of the prior and critical region for the Bayes factor test is only to specify the type I error. This is their only role sin...

PURPOSE To examine how the ischemia-reperfusion injury of latissimus dorsi-cutaneous maximus (LDCM) musculocutaneous flap affects the microcirculatory (flap's skin surface) and hemorheological parameters, and whether an intraoperative deterioration would predictively suggest flap failure in the postoperative period. METHODS Ten healthy male rats were subjected to the study. In Group I the lef...

PURPOSE The aim of this report is dosimetric evaluation for an intraoperative fusion computed tomography (CT) as a superior predictor of 1-month CT based dosimetry in comparison to transrectal ultrasound (TRUS) in permanent interstitial prostate brachytherapy. MATERIAL AND METHODS Data of 65 patients treated with seed implantation were analyzed. All procedures has been performed with patients...

BACKGROUND Portal hypertension is a major risk factor for hepatic failure or bleeding in patients who have undergone hepatectomy, but it cannot be measured indirectly. We attempted to evaluate the intraoperative ultrasonography parameters that correlate with portal pressure (PP) in patients undergoing hepatectomy. METHODS We examined 30 patients in whom PP was directly measured during surgery...

Objectives: Vitreous and retinal (VR) surgery with or without scleral buckling is associated with significant postoperative pain in adults, and recent studies have addressed the effect of retro or peribulbar block on these parameters. VR surgery in children has received little attention regarding the incidence of pain and the role of regional anesthesia in modifying these parameters. In this st...

BACKGROUND/AIM Cesarean myomectomy is a controversial issue. It was considered relatively contraindicated for many years due to increased risk of intraoperative hemorrhage. Recent studies showed that cesarean myomectomy in some women may not be associated with increased morbidity. The aim of the study was to determine the causes and risk factors for intraoperative hemorrhage in patients subject...
