OBJECTIVE The purpose of our study was to evaluate the utility of single-shot spin-echo echo-planar diffusion-weighted imaging (DWI) using a b value of 400-500 s/mm(2) for depicting peritoneal tumors. MATERIALS AND METHODS Thirty-four consecutive oncology patients underwent preoperative abdominal and pelvic MRI for tumor staging. MRI included breath-hold(More)
BACKGROUND Evaluation of peritoneal metastases by computed tomography (CT) scans is challenging and has been reported to be inaccurate. METHODS A multi-institutional prospective observational registry study of patients with peritoneal carcinomatosis from colorectal cancer was conducted and a subset analysis was performed to examine peritoneal cancer index(More)
PURPOSE To compare the accuracy of MRI and CT for predicting the Peritoneal Cancer Index (PCI) preoperatively compared with the PCI tabulated at surgery. METHODS Twenty-two patients underwent preoperative MRI and CT scanning followed by cytoreductive surgery for appendiceal (n = 17) and ovarian (n = 5) cancer. MR and CT examinations were retrospectively(More)
Six patients with unresectable carcinoma of the esophagus received a combined course of external radiation therapy (1000 rads in four fractions in four days commencing on day 2) combined with constant infusional 5-fluorouracil (20 mg/kg every 24 hours for five days beginning on day 1). This program was repeated every other week to give a total x-ray dose of(More)
Masticatory mucosa around implants may be useful to enhance esthetics and/or plaque control. This study proposes simplified guidelines for maintaining or obtaining a minimal amount of masticatory mucosa around submerged implants in cases of partial edentulism, and for keeping the need for additional surgery to a minimum. Free gingival grafts were used in(More)
PURPOSE To compare fat-suppressed, gadolinium-enhanced, breath-hold magnetic resonance (MR) imaging after administration of dilute oral barium solution with unenhanced MR imaging and computed tomography (CT) in the detection of peritoneal tumors. MATERIALS AND METHODS In 24 patients in whom peritoneal tumor was known or suspected, double-contrast MR(More)
We report the first study of the application of excimer lasers in dentistry for the treatment of dental root canals. High-energy ultraviolet (UV) radiation emitted by an XeCl excimer laser (308 nm) and delivered through suitable optical fibers can be used to remove residual organic tissue from the canals. To this aim, UV ablation thresholds of dental(More)
The purpose of this study was to determine the safety, toxicity, and antitumor immune response following S.C. immunizations with a mixture of irradiated, autologous tumor cells and autologous fibroblasts that were genetically modified to express the gene for interleukin 2 (IL-2) in patients with colorectal carcinoma. Ten patients were treated with a fixed(More)
Liver metastases are a common cause of death in colon carcinoma. The dual blood supply of the liver permits regional perfusion while hepatic catabolism fo 5-fluorouracil (FU), floxuridine (FUdR) permit higher drug exposures than systemic (IV) administration. We have studied the effect of continuous intra-arterial chemotherapy (FU: 5-10 mg/kg/day and FUdR:(More)
A case of congenitally missing maxillary lateral incisors is presented to illustrate a modification of Abrams's roll technique. Buccal releasing incisions are avoided by using an intrasulcular incision on the adjacent teeth. The tissue overlying the cover screw is transferred between the buccal cortical bone and the buccal masticatory mucosa, thus(More)
