Candrive-Development of a Risk Stratification Tool for Older Drivers.

Background: Assessing an older adult's fitness-to-drive is an important part of clinical decision making. However, most existing risk prediction tools only have a dichotomous design, which does not account for subtle differences in risk status for patients with complex medical conditions or changes over time. Our objective was to develop an older driver risk stratification tool (RST) to screen for medical fitness-to-drive in older adults.

Self-reported violations, errors and lapses for older drivers: Measuring the change in frequency of aberrant driving behaviours across five time-points.

The current study aimed to: 1. to confirm the 21-item, three-factor Driver Behaviour Questionnaire (DBQ) structure suggested by Koppel et al. (2018) within an independent sample of Canadian older drivers; 2.

WITHDRAWN: Intensity of exercise for the treatment of osteoarthritis.

Background: Therapeutic exercise is used as one modality to treat people with osteoarthritis (OA).

Objectives: To evaluate the effectiveness of therapeutic exercise of differing intensities on objective and subjective measures of disease activity in people with OA.

Search Methods: We searched MEDLINE, EMBASE, Pedro, Current Contents, Sports Discus and CINAHL up to and including December 2002.

Hepatoid adenocarcinoma in the urinary bladder. Unusual localization of a newly recognized tumor type.

A tumor mass resected from the anterior bladder wall of a 68-year-old woman displayed unusual histologic features: sheets of hepatoid cells merging focally with a secondary glandular pattern of adenocarcinoma. Intracytoplasmic hyaline globules and bile production within the solid areas supported the impression of hepatocytic differentiation. Immunoreactivity for alpha-fetoprotein (AFP) and alpha-1-antitrypsin and a striking canalicular immunostaining pattern for carcinoembryonic antigen and epithelial membrane antigen all indicate hepatocellular differentiation within this bladder tumor.

Adamantinoma. A case report with aspiration cytology and differential diagnostic and immunohistochemical considerations.

Fine needle aspiration biopsy of bone lesions is routinely used in the metastatic workup of patients with radiographically suspicious areas. However, caution must be used when interpreting smears from aspirates performed on primary bone neoplasms. These tumors are often heterogeneous, and problems with sampling may be encountered.

A comparison of excimer laser, thermal probe, and mechanical devices for recanalizing occluded human arteries.

To evaluate the mechanism of excimer laser recanalization and compare the results with those of laser-assisted thermal probe recanalization and mechanical recanalization, a total of 42 human atherosclerotic totally occluded arterial segments (2-15 cm long) were recanalized by excimer laser with a 400-800 micron quartz fiber pulsed at 20 Hz with 50 mJ/mm2 of energy (n = 21), an Argon heated thermal probe at 10-12 watts (n = 11), a guidewire directed through a 6 Fr multipurpose catheter, or an angioplasty balloon catheter (n = 10). On histologic examination, the excimer laster created a single round lumen or multiple lumens ("Swiss-cheese" like appearance) with no evidence of thermal injury at the perimeter of the lumen. The incidence of perforation in vitro was less with an excimer laser catherter (8/21 or 38%) than with the thermal prove (10/11 or 91%) (p less than 0.

Laser-assisted thermal angioplasty in human peripheral artery occlusions: mechanism of recanalization.

Recanalization of completely occluded superficial femoral or popliteal arteries was attempted in 18 patients with use of an Argon laser-mediated thermal probe. The length of the occluded segments varied between 0.5 and 26.

Ablation of bone and methacrylate by a prototype mid-infrared erbium:YAG laser.

An erbium:YAG laser was used to generate 200-microseconds pulses of mid-infrared 2.94-microns light in both the single and multimode configurations. Laser pulses were focused on the surfaces of both rabbit long bones and methacrylate blocks, and the tissue response was examined histologically.
