PURPOSE We evaluated the effectiveness of local bladder hyperthermia and intravesical chemotherapy compared to intravesical chemotherapy alone in the treatment of superficial transitional cell carcinoma. MATERIALS AND METHODS A new system designed to deliver simultaneously local bladder hyperthermia and intravesical chemotherapy has been developed at our(More)
AIMS To assess the effect of local hyperthermia on the systemic absorption of mitomycin C (MMC) during intravesical chemotherapy for the treatment of superficial transitional cell carcinoma of the bladder, and to establish the likely safety of this procedure. METHODS Group 1 (n = 12) received 20 mg intravesical MMC plus local hyperthermia, group 2 (n =(More)
PURPOSE The role of a combined regimen of local hyperthermia and topical chemotherapy in patients with multifocal and recurrent superficial bladder tumors not curable by transurethral resection was evaluated in a neoadjuvant organ sparing clinical study. MATERIALS AND METHODS A total of 19 patients with multifocal, superficial grades 1 to 3 bladder tumors(More)
Critically ill patients, eligible for admission into intensive care units (ICUs), are often hospitalized in other wards due to a lack of ICU beds. Differences in morbidity between patients managed in ICUs and elsewhere are unknown, specifically the morbidity related to hospital-acquired infection. Patients fitting ICU admission criteria were identified by(More)
Twelve patients suffering from superficial transitional cell carcinoma of the bladder underwent treatment combining simultaneous mitomycin C topical instillation and local endocavitary hyperthermia as a preoperative adjunct to transurethral resection in a preliminary clinical study. A specifically designed system to deliver and monitor local bladder(More)
High frequency positive pressure ventilation (HFPPV) was compared with normal frequency positive pressure ventilation (NFPPV) during diagnostic fiberoptic-bronchoscopy. HFPPV was achieved by a simple modification of the Minivent, and gave satisfactory alveolar ventilation and oxygenation. In all 11 patients and over periods of at least 40 min, HFPPV gave(More)
BACKGROUND Sleepiness at the wheel is the main cause of approximately a fifth of road traffic accidents. The driver will often feel drowsy before the accident, therefore preventive measures can be taken in order to stay alert. AIM To estimate sleepiness among sleep deprived drivers and to explore methods they use to stay alert. METHODS We choose three(More)
