To analyze early and delayed results of various variants of circular tracheal resection (CTR) with anastomosis, to determine the safest approach, dates and conditions of correction, features of postoperative period in patients after previous tracheal surgery. |
MATERIAL AND METHODS |
There were 831 patients with cicatricial tracheal stenosis. CTR was made in 330 (39.7%) patients. Most patients had previous prolonged ICU-stay. The patients were divided into 4 groups. Group 1 consisted of 61 (18.5%) patients after previous prolonged tracheal stenting. Group 2 included 45 (13.6%) patients who underwen... |
CONCLUSION |
Tracheal resection after preliminary stenting or tracheostomy is quite safe and technically feasible. Stenting allows postponing radical surgery for correction of concomitant diseases and closure of tracheostomy as a focus of infection within the surgical approach and further tracheal anastomosis. Tracheal resection wi... |

PURPOSE |
The aim of this human study was to apply novel topographical mapping techniques to investigate sensory and EMG manifestations of delayed-onset muscle soreness (DOMS) in multiple locations of the quadriceps. |
METHODS |
Bipolar surface EMG signals were recorded from 11 healthy men with 15 pairs of electrodes located at 10, 20, 30, 40, and 50% of the distance from the medial, superior, and lateral border of the patella to the anterior superior iliac spine. Subjects performed sustained isometric knee extensions at 40% of the maximal for... |
RESULTS |
Time to task failure was reduced after the eccentric exercise (mean +/- SD, 56.6 +/- 23 s before the eccentric exercise; 34.3 +/- 18.9 s at 24 h after exercise; and 34.3 +/- 14.4 s at 48 h after exercise). During the postexercise sustained contractions, EMG average rectified value (ARV) significantly decreased over tim... |
CONCLUSION |
Novel topographical mapping of both surface EMG and PPT of the quadriceps showed site-dependent effects of eccentric exercise, probably attributable to variations in the morphological and architectural characteristics of the muscle fibers. Greater manifestations of DOMS in the distal region of the quadriceps may indica... |
