Acute subclavian artery occlusion by blunt trauma: a case report.

We report a case of acute left subclavian artery occlusion after blunt trauma, presenting with symptoms of acute left upper arm ischemia. Angiography was performed to confirm the injury. The injured left subclavian artery was approached via left thoracotomy, and an interposition graft was placed.

Delayed operative intervention in the management of traumatic descending thoracic aortic rupture.

Background: Outcomes may be improved by purposefully delaying surgical intervention of the traumatically ruptured descending thoracic aorta.

Methods: Fifty-seven patient records identified through the Trauma Registry of a level 1 trauma center between January 1993 and April 2002 were retrospectively analyzed between groups who underwent "clamp-and-sew" versus partial left heart bypass repair techniques and between emergent versus delayed repair.

Results: Thirty-two (56%) of 57 patients were male.

Determination of estrogens in sludge and sediments by liquid extraction and GC/MS/MS.

Two methods have been developed that enable the determination of estrogens down to 2 ng/g in digested and activated sludge from domestic sewage treatment plants (STPs) and down to 0.2 ng/g in freshwater sediments. The method for sludge analysis consists of solvent extraction; a gel permeation chromatography (GPC) cleanup step, a 1 g silica gel column; and finally, detection by GC-ion trap MS/MS of the silylated estrogens with MSTFA.

Concomitant weekly cisplatin and thoracic radiotherapy for Pancoast tumors of the lung: pilot experience of the San Antonio Cancer Institute.

Pancoast (superior sulcus tumors) comprise a subset of non-small-cell lung cancers that have a unique clinical presentation by virtue of the locoregional pattern of disease progression. We herein report a brief report on our group's pilot experience in managing these challenging lung neoplasms with an aggressive concomitant modality approach. These results and those of the recent Southwest Oncology-lead Intergroup prospective phase 2 trial (SWOG-9416/INT-0160) support the use of concomitant chemoradiation followed by an attempt at surgical resection.
