The objective of the study was to ascertain the completeness of Workers' Compensation files to identify fatal occupational injuries. The number of fatalities was counted using two independent sources: the Quebec Workers' Compensation Board (QWCB), and the Coroner's Death Certificates (CDCs), for the years 1987 and 1988. The observed number of cases was 352.(More)

OBJECTIVE Our objectives were threefold: to evaluate the sensitivity and specificity of laryngeal computed tomography (CT) in the evaluation of laryngeal cancer, to determine the positive and negative predictive values of CT in assessing laryngeal cancer with respect to patient outcome, and to compare the CT staging of laryngeal cancer with endoscopy.

BACKGROUND AND OBJECTIVES We sought to determine if spinal anesthesia is more difficult to perform in the elderly. METHODS All spinal anesthetics administered over 18 months by 18 anesthesiologists were eligible. We excluded anesthetics for hip fractures and cesarean deliveries. We recorded time to completion, number of spinal needles used, and number of(More)
The authors sought to compare time efficiency of spinal versus general anesthesia. The charts of 106 consecutive patients who had undergone a vaginal hysterectomy were analyzed. This analysis divided the patients into three groups: Group 1, spinal anesthesia; Group 2, general anesthesia; Group 3, spinal anesthesia with subsequent general anesthesia. The(More)
Cortical blindness is a well described neuro-ophthalmologic complication of angiography due to neurotoxicity following contrast media exposure. A rarer association with retrograde amnesia has also been reported. Since ischemic stroke due to embolism remains the most common aetiology of neurological complications of diagnostic and therapeutic arterial(More)
The objective of this study was to describe fatal occupational electrocutions that occurred in Quebec between 1981 and 1988 and propose a classification suitable for setting up a prevention agenda. Of 63 fatalities, an investigation report was available in 57 (90.5%). They all occurred among males, 70.2% of whom were under the age of 35; 49.1% were(More)
