Acivicin (AT-125) is a glutamine antagonist with dose-limiting, schedule-dependent CNS toxicity and predictable CSF penetration after intravenous administration. Because of these properties, a trial in CNS malignancies was initiated. Thirty-two patients with recurrent or residual malignant astrocytomas were treated with AT-125. The majority of patients had(More)
Percutaneous transhepatic catheterization of the biliary tree was performed in 41 patients with obstructive jaundice. In 39 patients, the catheter was successfully advanced past the obstructing lesion into the distal common duct and duodenum to establish internal biliary drainage. The remaining two patients had the obstructed biliary tract drained(More)
Since many of the proposed etiologic factors leading to gastric stress ulceration involve stimulation of calcium influx, the effect of verapamil, a potent calcium channel blocker, on the gastric mucosa in cold-restrained inbred rats was assessed. Twenty-nine rats received intraperitoneal normal saline (2 ml) while the experimental group (N = 29) received 1(More)
Twenty-three evaluable patients with advanced gastric adenocarcinoma were treated with trimetrexate at doses of 8–12 mg/m2 intravenously daily for five days, with cycles repeated every 21 days. One complete response was seen for an overall response rate of 4% (95% confidence interval 0–22%). Hematologie toxicities of grade ≥ 3 were seen in 10/23 patients,(More)
Consecutive records of 608 patients who underwent appendectomy for suspected acute appendicitis were retrospectively analyzed to evaluated the necessity and usefulness of intraoperative cultures. There were no operative deaths and postoperative infectious morbidity was 6.4%. Positive cultures were only weakly predictive of postoperative infection. Culture(More)
BACKGROUND Appropriate adjuvant chemotherapy for resected head and neck cancer patients has yet to be defined. Multiple trials have noted trends toward improved disease-free survival and local control. The Southwest Oncology Group undertook a feasibility trial of postoperative cisplatin and radiotherapy followed by three cycles of cisplatin and(More)
Computed tomographic scanning of the abdomen in 50 patients evaluated for suspected intraabdominal abscess resulted in an overall accuracy of 92 percent. It proved the most accurate diagnostic tool in determining the presence of intraabdominal abscess. Computed tomography of the abdomen is a useful diagnostic adjunct to clinical judgment and may assist in(More)
