Previously this laboratory demonstrated that forelimb removal at birth in rats results in the invasion of the cuneate nucleus by sciatic nerve axons and the development of cuneothalamic cells with receptive fields that include both the forelimb-stump and the hindlimb. However, unit-cluster recordings from primary somatosensory cortex (SI) of these animals revealed few sites in the forelimb-stum...

The features of unlesioned and lesioned trochlear nerves of goldfish have been examined electron microscopically. Lesioned nerves were studied between 1 and 107 days after cutting or crushing the nerve. Unlesioned nerves contained, on average, 77 myelinated axons and 19 unmyelinated axons. The latter were found in 1-2 fascicles per nerve. A basal lamina surrounded each myelinated axon and fasci...

2 Present address: Columbia Medical Center, 630 W. 168th St., New York, N. Y. 10032. The critical relationship between accurate fit of a prosthesis and amputee comfort and function constitutes the foundation of all prosthetic fitting. Consequently, one of the most important features of a lower-extremity prosthesis is the distribution of the pressures applied to the stump by the socket. Since Wo...

conclusions retrograde laparoscopic appendicectomy using single polymer clip makes easy access to operating in complicated and non-complicated appendicitis. results four patients (15.4%) were converted to open surgery; three patients in group i and one in group ii. four patients developed postoperative complications; three patients in group i and one in group ii. operative time was less in grou...

INTRODUCTION Bronchial stump aspergillosis is a rare entity characterized by cough and hemoptysis. CASE PRESENTATION We report the case of a 58-year-old Caucasian woman who developed bronchial stump aspergillosis two years after a left upper lobe resection for lung cancer. Bronchial stump aspergillosis was diagnosed as a result of a focus of increased fluorodeoxyglucose activity in a follow-u...

A series of 9 patients have experienced hemisphere and retinal ischemia at an interval after occlusion of appropriate internal carotid arteries. All had radiological evidence of a persisting proximal stump to the occluded artery and, in most, pathological evidence of thrombotic material attached to atheromatous lesions within the stump. Thromboembolism from the stump via the anastomotic supply ...

With a "headless" humerus active abduction and elevation of the arm are hardly possible. Especially if the humeral head was removed because of an infection, shoulder fusion is often the only safe solution for this disabling condition. Large corticocancellous, autologous bone grafts are interposed between the thin humeral stump on one side and its broad glenoid-acromion counterpart on the other....

BACKGROUND There is little information available to inform choice of technique for appendiceal stump control in pediatric laparoscopic appendectomy (LA). We compared complications (stump leak, intra-abdominal abscess formation [IAA], surgical site infection [SSI]) in children undergoing LA for perforated (PA) and nonperforated appendicitis (NPA) by technique of appendiceal stump control. METH...

Intussusception of the appendix in adult represents an uncommon entity. We report a 54-year old woman who underwent an appendectomy 24 years previously and who was hospitalized for changes in bowel habits and periumbilical and epigastric pain. A sessile polypoid tumor of cecum was discovered during colonoscopy, which was removed. Histopathological examination showed that it was the case of an i...

the log damage and value loss were examined by felling and bucking function, species, and damage type, in kheyrud forest in namkhaneh district in the hyrcanian forest of iran. in order to calculate the wood value following tree felling and bucking, 250 trees and 167 logs consisting of beech and hornbeam species were measured. there were five types of damage recorded following the tree felling o...
