Nethra H Nanjundaswamy, Vinay Marulasiddappa
BACKGROUND: Insertion of skull pin induces a significant increase in heart rate (HR), blood pressure (BP) and intracranial pressure. Alpha 2 agonist clonidine and intravenous (i.v.) lignocaine are effective in attenuating stress response. Local infiltration of pin site and scalp block with lignocaine are commonly used techniques for prevention of hemodynamic response to skull pin insertion. We compared the effectiveness of i.v. clonidine infusion and i.v. lignocaine infusion in suppressing the hemodynamic response to skull pin head holder insertion...

BACKGROUND: It takes many years to acquire abilities and technical skills necessary to do a good work as a doctor and even more years, for being "good professionals". Much of this training is based on old teaching schemes, but medicine has changed. So far no studies in our medium addressing the problem are known. The aim of this paper was to determine the level of professionalism in physicians that work in a second-level hospital. METHODS: Descriptive cross-sectional study...

INTRODUCTION: Percutaneous discectomy is a disc decompression technique approved by the FDA that is useful to improve pain caused by a herniated disc. However, its practice is under discussion because the benefits of the technique are controversial. OBJECTIVES: To describe the clinical course of patients with low lumbar disc herniation (L4-L5, L5-S1) treated by percutaneous surgery within one year of surgery and prove that it is a useful surgical option for the relief of symptoms caused by this pathological entity...

#8
Hengrui Sun, Bruce Binkowitz, Gary G Koch
Multiplicity is an important statistical issue that arises in clinical trials when the efficacy of the test treatment is evaluated in multiple ways. The major concern for multiplicity is that uncontrolled multiple assessments lead to inflated family-wise Type I error, and they thereby undermine the integrity of the statistical inferences. Multiplicity comes from different sources, for example, making inferences either on the overall population or some pre-specified sub-populations, while multiple endpoints need to be evaluated for each population...

Clinical polysomnography (PSG) databases are a rich resource in the era of "big data" analytics. We explore the uses and potential pitfalls of clinical data mining of PSG using statistical principles and analysis of clinical data from our sleep center. We performed retrospective analysis of self-reported and objective PSG data from adults who underwent overnight PSG (diagnostic tests, n=1835). Self-reported symptoms overlapped markedly between the two most common categories, insomnia and sleep apnea, with the majority reporting symptoms of both disorders...

PURPOSE: Little is known about the incidence of nephrolithiasis in the U.S. Navy, and Navy pilots must be kidney stone-free and are often referred for treatment of small asymptomatic stones. The primary objectives of this study were to determine the incidence of nephrolithiasis, CT scans performed, proportion undergoing treatment, and incidence of stone-related mishaps of Navy pilots compared with other Navy personnel. MATERIALS AND METHODS: We performed a retrospective study of all Navy service members from 2002-2011 for nephrolithiasis (based on ICD-9 stone codes) to determine the above rates, and reviewed Naval Safety Center (NSC) data for a history of accidents associated with nephrolithiasis...
