Background: Majority of urologists prefer the usual prone position for percutaneous nephrolithotomy (PCNL) but due to various disadvantages PCNL, several alternative positions are being used. Aims and Objectives: The aim study was compare surgical outcomes PCNL performed using supine with those in position. Materials Methods: This a prospective observational study. After applying inclusion crit...

CT colonography (CTC) is a minimally invasive screening technique for colorectal polyps and colon cancer. Most CTC protocols acquire both prone and supine images to improve the visualization of the lumen wall, reduce false positives, and improve sensitivity. Comparisons between the prone and supine images can be facilitated by computerized registration between the scans. In this paper, an algor...

We investigated the temperamental traits high-intensity pleasure (temperamental activation) and shyness (temperamental inhibition) in relation to autonomic function as measured by heart rate (HR), respiratory sinus arrhythmia (RSA), and baroreflex sensitivity (BRS) in 938 10-13-year-old preadolescents from a population cohort. Temperament was evaluated by parent reports on the Revised Early Ado...

INTRODUCTION Due to the potential for intramuscular fluid shifts from changing body position, researchers often utilize a 10- to 15-min period of supine rest as a standardizing procedure prior to ultrasound assessment of the lower limbs. However, no previous research has observed the changes in muscle morphological characteristics via ultrasonography of the lower limbs depending on the length o...

Prone 201Tl myocardial perfusion SPECT has been shown to improve left ventricular inferior wall counts compared to supine imaging, thus minimizing diaphragmatic attenuation. Prone SPECT quantitative normal limits were developed and prospectively applied to 36 patients who had coronary angiography. The prone imaging table used had a cut-out under cardiac area which increased the average myocardi...

We measured the isocapnic hypoxic ventilatory response and the hypercapnic ventilatory response by using rebreathing techniques in five normal subjects (ages 37-47 yr) before, during, and after 16 days of exposure to microgravity (microG). Control measurements were performed with the subjects in the standing and supine postures. In both microG and in the supine position, the hypoxic ventilatory...

[Purpose] The purpose of this study was to study the changes in pulmonary functions in relation to lying positions of experimental participants. [Subjects and Methods] Twenty participants participated in this experiment. Measurements were taken in the supine position, the left side-lying position, the right side-lying position, and the prone position. Vital capacity (VC) was evaluated using a F...

CT colonography (CTC) is a minimally invasive screening technique for colorectal polyps and colon cancer. Since electronic colon cleansing (ECC) cannot completely remove the presence of pseudo-polyps, most CTC protocols acquire both prone and supine images to improve the visualization of the lumen wall and to reduce false positives. Comparisons between the prone and supine images can be facilit...

STUDY OBJECTIVE To compare the severity of sleep apneic events occurring in the supine posture vs the severity of sleep apneic events occurring in the lateral posture in patients with severe obstructive sleep apnea (OSA). DESIGN A retrospective analysis of apneic event variables in a group of 30 OSA patients who underwent a complete polysomnographic evaluation in our sleep disorders unit. P...

abstract study design: a cross-sectional non-experimental study. objectives: to collectively detect the reliability and feasibility of the five types of clinical tests that have been used to measure endurance of the trunk muscles in subjects with and without low back pain (lbp) and identify the sensitivity of each test to predict the probability of the occurrence oflbp. background: testing spin...
