In a review of five Dayton, Ohio, area hospitals during a six-year period, seven patients who were treated for an acquired arteriovenous (A-V) fistula after cardiac catheterization were identified. Four patients had undergone cardiac studies in area hospitals, while three were studied elsewhere. The four A-V fistulas after 23,291 cardiac catheterization(More)
In a 46-year-old man with Zollinger-Ellison syndrome, multiple imaging studies were negative for a primary gastrinoma. Preoperative endoscopic ultrasonography (EUS) revealed a 3.3-cm mass which appeared to be in the pancreatic head. During surgery, a celiac lymph node of the size of the mass seen by EUS was found, but the pancreatic head also felt firm and(More)
The role of ammonia released by the gut on hepatic glutamine handling and metabolism was studied in postabsorptive anesthesized male Sprague-Dawley rats at spontaneous and elevated arterial glutamine concentrations. Glutamine handling and metabolite release across both organ beds were studied using arteriovenous concentration differences and simultaneously(More)
Tracheal obstruction and superior vena cava (SVC) syndrome are rare complications of retrosternal goiter. These two conditions present a difficult diagnostic and therapeutic challenge. Malignancy is the most common cause of SVC syndrome. Determining whether SVC syndrome is due to a benign or malignant process is imperative before instituting treatment, but(More)
Cholecystectomy in the pregnant patient has been generally avoided because of the reported high incidence of associated fetal loss that has been linked to spontaneous and elective abortion during the first trimester and premature labor during the third trimester. Recent developments relating to diagnostic and anesthetic management and the use of tocolytic(More)
Although breast cancer follow-up guidelines emphasize the importance of clinical examinations, prior studies suggest a small fraction of local–regional events occurring after breast conservation are detected by examination alone. Our objective was to examine how local–regional events are detected in a contemporary, national cohort of high-risk breast cancer(More)
This study retrospectively evaluated the cost-effectiveness of laparoscopic cholecystectomy compared to open cholecystectomy in a single university-affiliated community hospital. The medical records of all patients that underwent laparoscopic cholecystectomy during 1990 and open cholecystectomy during 1989 in one hospital were reviewed. Hospital stay,(More)
