We have presented a case of internal herniation of small bowel through the sigmoid mesocolon in a pregnant woman. In patients with symptoms suggestive of bowel obstruction, even without a history of previous abdominal surgery, internal hernia must be included in the differential diagnosis.
Despite many reports of radiologic findings that may be suggestive of aortic injury, most authors believe the recognition of a widened mediastinum on chest film remains the sine qua non. Few studies have confirmed the widely held belief that the supine AP chest film is inaccurate in assessing the width of the mediastinal structures, and that one should use only the upright or sitting chest films. This study was undertaken to assess the accuracy of both upright and supine chest films in the evaluation of mediastinal widening after blunt deceleration chest injury. Both supine and upright sitting chest films were obtained immediately on arrival in the resuscitation areas for 55 patients. Twenty-one (38%) exhibited a mediastinum that appeared wide on supine view but within normal limits on the upright view, as attested by two radiologists. Aortography was not performed on any of these patients. Daily upright chest films, repeated until discharge, failed to demonstrate any change in mediastinal anatomy, and all patients recovered without incident. Twelve patients' films (22%) demonstrated widened mediastinum on both views, and these 12 patients underwent immediate aortography. Aortic rupture was revealed in four (33%). This study clarifies the diagnostic value of the upright chest film in assessing the mediastinum after blunt injury. It confirms the belief that supine films are not accurate, and that they may lead to numerous false positives and unnecessary aortograms. The initial upright or sitting chest film is accurate, and its use is cost-effective and time-saving for patient and physician.(ABSTRACT TRUNCATED AT 250 WORDS)

The treatment of massive upper gastrointestinal hemorrhage by gastric hypothermia was studied clinically in 23 patients: five with peptic ulcer, six with multiple gastric erosions, nine with portal hypertension and varices, and three with coagulation defects. Hemorrhage was controlled in 13 of the patients. The high mortality (14 out of 23 patients) was attributed to the severity of the bleeding and to the underlying disease, particularly in patients with liver failure. This form of treatment is a useful method of treating selected patients with upper gastrointestinal hemorrhage.
