It may occur in such diverse locations as the uterus, breast, thyroid, lung, and upper gastrointestinal system. However, to date a primary mediastinal carcinosarcoma has not been reported in the literature. q 2003 Elsevier B.V. All rights reserved.

Hence, this study was designed to study nerve regeneration after unclipping the TSC. Methods The bilateral TSCs of six goats were studied; the goats were separated into three groups (groups I, II, and III) during excision, clipping, and unclipping. During surgery, the TSCs were excised with a scalpel in group I and clipped in groups II and III. In group III, the clips were removed 1 month postoperatively and observed for possible nerve healing for 1 month. All TSCs were examined histologically following en block resection at 1 month postoperatively in groups I and II and at 2 months postoperatively in group III. Results Inflammation in nerve sections was noted following clip removal. Furthermore, there was significant degeneration and cell infiltration in the nerve fibers of the clipped regions. The Schwann cells around the peripheral nerve endings in the unclipped regions facilitated nerve transmission by reconstitution of myelin. Conclusion Clipping the TSC can cause histologic degeneration; however, histologic nerve regeneration occurs after unclipping.

The efficacy of bio-absorbable oxidized regenerated cellulose in preventing post-operative pericardial adhesions was evaluated in the present study. Forty New Zealand white rabbits were divided into four groups of 10. In all rabbits an area of pericardium (2 × 2 cm) was excised. The wound was left open in groups 1 and 2 but replaced with bio-absorbable oxidized regenerated cellulose in groups 3 and 4. Rabbits in groups 1 and 3 were killed 3 weeks after surgery and those in groups 2 and 4 were killed at 6 weeks. Groups 1 and 2 showed more severe pericardial adhesions, more fibrous reaction and increased visibility of coronary vessels than groups 3 and 4, although there was no difference in inflammation. Light microscopy showed a mesothelium-like cell layer in groups 3 and 4. It is concluded that bio-absorbable oxidized regenerated cellulose may be suitable i...

Recurrent syncope following a right pneumonectomy in a 21-year-old woman was treated by insertion of an expandable silicone prosthesis into the pneumonectomy space.

The aim of this study was to compare pathologically proven N0 lymph nodes obtained during mediastinoscopy with p53 gene mutation, and to correlate these with postoperative recurrence. Thirty patients undergoing mediastinoscopy for staging of non-small cell lung carcinoma were studied prospectively. Standard cervical mediastinoscopy was performed in all cases, and the specimens were divided into two pieces for histopathological and genetic investigations. All but one of the patients were male, and the mean age was 61.2 years (range, 42–74 years). Although the histopathology was negative in all cases, p53 gene mutation was observed in 6 (20%) patients. Recurrence was detected in 3 patients who had negative histopathology but were positive for p53 mutation, and in one who had negative histopathology and no p53 mutation. Patients with pathologically N0 disease and p53 gene mutation must be ca...
