An etiologic concept linking an impaired axial motor control system to the structural deformity of idiopathic scoliosis (ISc) is proposed. Postural studies reveal that during quiet stance, adaptation is marked in conditions associated with visual control of sway, particularly of lateral sway; during imposed perturbations of the body, destabilized postural(More)
Background and aims: This study evaluated the effect of transanal endoscopic microsurgery (TEM) on anorectal sphincter functions and determined the risk factors for anorectal dysfunctions (including incontinence). Patients and methods: A study group of 33 patients with small, mobile rectal tumors (adenoma and carcinoma) located up to 12 cm from the anal(More)
This study aimed to evaluate the optimal timing of preemptive analgesia with bupivacaine peritoneal instillation in a prospective, randomized, double-blind, placebo-controlled trial. In this study, 120 patients qualified for laparoscopic cholecystectomy were randomized to four groups. Group A received 2 mg/kg of bupivacaine in 200 ml of normal saline before(More)
Aim: This study aimed to investigate the advantages and disadvantages of LP (7 mmHg) in comparison to SP (12 mm Hg) pneumoperitoneum in a prospective randomized clinical trial. Materials and Methods: 148 consecutive patients qualified for laparoscopic cholecystectomy (LC) due to uncomplicated symptomatic gallstones were randomized to either SPLC or LPLC.(More)
Doppler-guided hemorrhoidal artery ligation (DGHAL), as a method of treating hemorrhoidal disease, is currently used in many centers across Europe, Asia, and Australia. The aim of our study was to evaluate the clinical effectiveness and functional results of DGHAL as estimated by means of anorectal manometry. Between 2000 and 2006 the DGHAL procedure was(More)
UNLABELLED The effects of different pressure values of pneumoperitoneum on the activity of the autonomic nervous system (ANS) have not been investigated in detail. In this prospective study, 20 patients qualified for laparoscopic cholecystectomy were randomised to either low-pressure (LP = 7 mmHg) or standard-pressure (SP = 12 mmHg) pneumoperitoneum groups,(More)
OBJECTIVE A modification of Doppler guided haemorrhoidal artery ligation (DGHAL) to include the addition of recto-anal repair is reported. Preliminary results of function and safety of third and fourth degree haemorrhoidals are given. METHOD Thirty patients underwent DGHAL combined with recto-anal-repair (RAR). Each had rectal examination, anorectal(More)
Gastro-esophageal reflux disease (GERD) is the result of the acid contents regurgitation back from the stomach into the esophagus. According to the endoscopic findings, GERD can be divided into two main forms: non-erosive (NERD) and erosive reflux esophagitis. The pathogenesis of GERD is associated with the impaired function of the antireflux barrier.(More)
PURPOSE The purpose of the study was the non-invasive investigation of the innervation zone (IZ) location of the gracilis muscle of both thighs by means of surface electromyography (EMG). MATERIALS AND METHODS Multichannel EMG signals were detected by means of a flexible array of 16 equally spaced silver bar electrodes. Tests were performed on both(More)
Though primary and secondary duodenogastric reflux (DGR) have been accepted in the medical literature as separate clinical units, reliable and standardised methods of detection have not been known since long. Therefore, the role of DGR in the pathogenesis of upper GI tract diseases makes a problem. So far applied measurement techniques allow only indirect(More)
