The effect of L-arginine and aprotinin on intestinal ischemia-reperfusion injury.

Background: Intestinal ischemia/reperfusion (I/R) results in local mucosal injury, systemic injuries, and organ dysfunction. These injuries are characterized by altered microvascular and epithelial permeability and villous damage. Activation of neutrophils, platelets, and endothelial factors are known to be involved in this process.

Paclitaxel (175 mg/m2) plus carboplatin (6 AUC) versus paclitaxel (225 mg/m2) plus carboplatin (6 AUC) in advanced non-small-cell lung cancer (NSCLC): a multicenter randomized trial. Hellenic Cooperative Oncology Group (HeCOG).

Purpose: The combination of paclitaxel and carboplatin has become a widely used regimen in NSCLC due to phase II reports of moderate toxicity, reasonable activity and easy outpatient administration. Purpose of our present prospective study was to evaluate the dose response relationship of paclitaxel.

Patients And Methods: Since July 1996, 198 patients with non-operable NSCLC and measurable disease without previous chemotherapy entered the trial.

Metastatic breast disease 40 years after the initial diagnosis.

This is the case of a patient with metastatic disease diagnosed 40 years after a radical mastectomy which was followed by radiation treatment for breast cancer. The patient had nonspecific symptoms for 3 years, and a lymph node biopsy revealed the underlying cause to be recurrent breast cancer. Excision of the largest metastases combined with chemotherapy resulted in a further 3-year remission.

An expert system for assigning patients into clinical trials based on Bayesian networks.

Assigning patients into clinical trials is a knowledge and data intensive task. Eligibility determination for entry into a clinical trial is based upon specific inclusion and exclusion criteria. This paper investigates the use of an excerpt system to assist the physician through this task.

An automated patient registration and treatment randomization system.

Centralized patient registration and treatment randomization for multicenter clinical trials has many advantages over other approaches. Our Automated Patient Registration and Treatment Randomization system is a fully automated Interactive Voice Response, microcomputer-based application which can operate unattended and is continuously available to provide patient registration and treatment randomization. Several techniques are employed to ensure security of the system and validity and accuracy of the data.
