PURPOSE This prospective, nonrandomized trial evaluated a percutaneous isolated chemotherapy perfusion approach for treating advanced primary and metastatic liver tumors. Chemotherapy was administered via hepatic artery catheter and hepatic venous blood isolated by a novel percutaneous double-balloon inferior vena cava (IVC) catheter was passed through a(More)
This report presents the results of an original investigation designed to determine (1) the prevalence in the natural dentition of a maxillary midline located in the exact middle of the mouth using the philtrum as the most reliable guide and (2) the percentage of people in whom the maxillary and mandibular midlines precisely coincide with each other.(More)
BACKGROUND Hepatic arterial infusion of doxorubicin has produced tumor response in hepatic malignancies; however, the limited success of these treatments is related in part to dose-limiting systemic toxicities. The purpose of this study was to determine whether a novel venous isolation-chemofiltration system could limit systemic exposure to doxorubicin(More)
Chemotherapy for primary or metastatic hepatic malignancy is limited by poor tumor response and dose-related systemic toxicity. As an alternative to chemotherapy infusion by vein or by the hepatic artery, the authors have developed a percutaneous technique of isolated liver perfusion that allows the regional delivery of high-dose chemotherapy to the liver(More)
When chemotherapeutic drugs with low liver extraction are used for hepatic arterial infusion (HAI), dosage limits are usually determined by systemic rather than hepatic toxicity. If such agents could be administered by HAI at dosages limited by hepatic toxicity, regional drug exposure and therapeutic efficacy might be significantly enhanced. We report(More)
BACKGROUND A study was undertaken to assess the long term physiological and clinical outcome in 79 patients with musculoskeletal disorders (73 neuromuscular, six of the chest wall) who received non-invasive ventilation for chronic respiratory failure over a period of 46 years. METHODS Vital capacity (VC) and carbon dioxide tension (PCO(2)) before and(More)
Changes in plaque pH and microhardness of bovine enamel slabs were evaluated with a seven-day intra-oral cariogenicity test (ICT). The test enamel slabs were mounted in prosthetic appliances with a Dacron mesh cover for enhancement of microbial colonization. Three percent solutions of sucrose, sorbitol, and xylitol were evaluated as four daily extra-oral(More)
