230 Canadian steelworkers with hypertension took part in a randomised trial to see if compliance with antihypertensive drug regimens could be improved. For care and follow-up these men were randomly allocated to see either their own family doctors outside working-hours or industrial physicians during work shifts; the same men were randomly allocated to(More)
BACKGROUND Endarterectomy reduces risk of stroke in certain patients with recently symptomatic internal carotid stenosis. However, investigators have made different recommendations about the degree of stenosis above which surgery is effective, partly because of differences between trials in the methods of measurement of stenosis. To accurately assess the(More)
38 hypertensive Canadian steelworkers who were neither compliant with medications nor at goal diastolic blood-pressure six months after starting treatment were allocated either to a control group or to an experimental group who were taught how to measure their own blood-pressures, asked to chart their home blood-pressures and pill taking, and taught how to(More)
BACKGROUND Endarterectomy benefits certain patients with carotid stenosis, but benefits are lessened by perioperative surgical risk. Acetylsalicylic acid lowers the risk of stroke in patients who have experienced transient ischaemic attack and stroke. We investigated appropriate doses and the role of acetylsalicylic acid in patients undergoing carotid(More)
BACKGROUND AND PURPOSE This study reports the surgical results in those patients who underwent carotid endarterectomy in the North American Symptomatic Carotid Endarterectomy Trial (NASCET). METHODS The rates of perioperative stroke and death at 30 days and the final assessment of stroke severity at 90 days were calculated. Regression modeling was used to(More)
The entry characteristics of 1367 patients enrolled into the Extracranial/Intracranial Bypass Study were examined to determine if site differences in intracranial and extracranial arterial lesions among racial groups could be explained by differences in risk factors. Blacks were more often hypertensive, diabetic, or cigarette smokers, while whites had(More)
OBJECTIVE To evaluate, through a systematic review of the current literature, the evidence-based outcomes of the use of platelet-rich plasma (PRP) for the treatment of tendon and ligament injuries. DATA SOURCES A search of English-language articles was performed in PubMed and EMBASE using keywords "PRP," "platelet plasma," and "platelet concentrate"(More)
A single-patient randomised clinical trial was used to determine optimum treatment for a patient with inflammation of her continent ileostomy. The trial proved to be feasible and acceptable to both patient and clinician. As a result, both the diagnosis of inflammation and the efficacy of metronidazole in treating it were confirmed. The trial design, in(More)
