Coronary heart disease (CHD) risk factors were studied in 250 monozygotic (MZ) and 264 dizygotic (DZ) male veteran twin pairs, aged 42-56. All coronary heart disease risk factors studied showed significant correlations in both MZ and DZ twins. Substantial genetic variation was detected for height, blood pressure, glucose intolerance, uric acid, plasma(More)
Toothpicks have been used since antiquity as instruments for mouth cleansing and as eating utensils. Toothpick injury to the gastrointestinal tract is often suspected only at the time of operation because patients rarely relate a history of swallowing toothpicks and most toothpicks are not radiopaque. The spectrum of toothpick injury to the gastrointestinal(More)
Although bougienage is widely used to treat benign esophageal stricture, the rate of stricture recurrence and the long-term effectiveness of bougienage are unknown. We studied the natural history of esophageal stricture in 154 patients in whom bougienage was used as primary therapy. Dilatations were considered successful in terms of relief or major(More)
Antipsychotic medications have altered the treatment of psychosis. The effect of typical agents is presumed to be associated with dopamine D2-receptor blockade. Response to these drugs can be evaluated by measuring target symptoms. Behavioural symptoms are generally first to respond, followed by affective symptoms, and then symptoms of disturbed cognition(More)
Anatomic dissection of the posterior interosseous nerve in 26 cadaver forearms was performed to assess variability in location, diameter, and branching patterns of the nerve. The purpose of our study was to determine the anatomic reliability of the posterior interosseous nerve at the distal forearm level as a potential donor nerve graft for segmental(More)
CONTEXT Identification of intestinal-type goblet cells (ITGCs) in hematoxylin-eosin-stained sections of esophageal biopsies is essential for the diagnosis of Barrett metaplasia. However, we have seen cases diagnosed as Barrett metaplasia based solely on cells that pose morphologic similarity to ITGCs on hematoxylin-eosin staining or stain positive with(More)
A prospective trial was performed in which biopsy and cytology specimens were obtained on 202 consecutive patients including 47 with esophageal or gastric carcinomas. The first biopsy specimen yielded a correct diagnosis in the majority of instances: 70% of gastric carcinomas and 93% of esophageal carcinomas. Three additional biopsy specimens increased the(More)
