Modeling and simulation of right ventricular volume measurement system during right heart catheterization.

Haemodynamic monitoring is necessary for the effective management of critically ill cardiac patients. Pulmonary artery catheterization has been used for monitoring the circulation, for measurement of intracardiac pressures and to estimate preload and afterload. However, pressures may not be accurate reflection of the circulation and simultaneous measurement of volumes would improve patient treatment.

Regional migratory osteoporosis in the knee: MRI findings in 22 patients and review of the literature.

Objective: Acute non-traumatic bone marrow edema (BME) in the knee is a common clinical problem. The aim of the present study is to present the MR imaging findings of the uncommon transient migratory pattern of this syndrome.

Materials And Methods: Twenty-two patients (21 men, 1 woman, age range 35-73 years, mean 49.

Combination of vinorelbine plus gemcitabine in previously treated patients with small cell lung cancer: a multicentre phase II study.

Purpose: To evaluate the efficacy and toxicity of the gemcitabine plus vinorelbine combination in pretreated patients with small cell lung cancer (SCLC).

Patients And Methods: Thirty-five pretreated patients (median age 59 years, PS: 0--1 in 97% and 2 in 3%) were treated with gemcitabine (1100 mg/m(2)) and vinorelbine (25mg/m(2)) on d1 and d8 every 3 weeks. Seven (20%) patients were treated with two prior regimens and 20 (57%) were refractory to front-line chemotherapy.
