BACKGROUND The impact of blood sampling in sitting vs supine positions on measurements of plasma metanephrines for diagnosis of pheochromocytoma is unknown. METHODS We compared plasma concentrations of free metanephrines in samples from patients with primary hypertension obtained after supine rest with those obtained in the sitting position without preceding rest. We also assessed the effects...

BACKGROUND Chiropractors use a variety of supine and prone leg checking procedures. Some, including the Allis test, purport to distinguish anatomic from functional leg length inequality. Although the reliability and to a lesser extent the validity of some leg checking procedures has been assessed, little is known on the Allis test. The present study mathematically models the test under a variet...

position changes are believed to increase the efficacy of phototherapy and this practice is routinely used in all neonatal departments in our country. the aim of this study was to determine the effect of routine turning on the total serum bilirubin (tsb) concentration versus only supine position. in a randomized clinical trial fifty healthy term jaundiced neonates who were admitted to the neona...

Purpose: To compare target coverage and organ at risk (OAR) sparing in the supine and prone positions with 3-dimensional conformal radiotherapy (3DCRT), intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) in lowand high-risk prostate radiotherapy cases. Materials and Methods: Using magnetic resonance images of five healthy volunteers, six treatment plans (supine ...

INTRODUCTION Supine percutaneous nephrolithotomy (PCNL) has become increasingly widespread during the last 2 decades. The aim of this study was to analyze the transition from prone to mainly supine PCNL in 2 endourologic centers. MATERIAL AND METHODS We retrospectively analyzed data on 214 consecutive supine PCNLs divided into the first (2011-2013) and last (2014-2016) 3 years of this study. ...

BACKGROUND Part II of this review examines the functional "short leg" or unloaded leg length alignment asymmetry, including the relationship between an anatomic and functional leg-length inequality. Based on the reviewed evidence, an outline for clinical decision making regarding functional and anatomic leg-length inequality will be provided. METHODS Online databases: Medline, CINAHL and Mant...

TOPIC: Critical Care TYPE: Original Investigations PURPOSE: Endotracheal intubation is performed to secure the airway for various elective and emergent indications, including surgeries, respiratory failure, altered mental status1. Currently, supine position most common used endotracheal intubation2. Intubations in non-supine can be necessary many situations, patients with back pain/lesions, inc...
