UNLABELLED Although allograft use for primary anterior cruciate ligament reconstruction has continued to increase during the last 10 years, concerns remain regarding the long-term function of allografts (primarily that they may stretch with time) and clinical efficacy compared with autograft tendons. We attempted to address these issues by prospectively(More)
BACKGROUND Nurse telephone advice (NTA) lines, a major initiative in primary health care reform, provide symptom triage and health information. Compliance studies utilizing database analysis are frequently limited to a defined population, such as children or Emergency Department (ED) users. OBJECTIVES To explore caller characteristics associated with(More)
BACKGROUND Liver stiffness measurement (LSM) by transient elastography (TE, FibroScan) is a validated method for noninvasively staging liver fibrosis. Most hepatic complications occur in patients with advanced fibrosis. Our objective was to determine the ability of LSM by TE to predict hepatic complications and mortality in a large cohort of patients with(More)
IMPORTANCE At the turn of the 21st century, studies evaluating the change in incidence of appendicitis over time have reported inconsistent findings. OBJECTIVES We compared the differences in the incidence of appendicitis derived from a pathology registry versus an administrative database in order to validate coding in administrative databases and(More)
We describe a technique of arthrodesis of the thumb metacarpophalangeal joint that we performed in 26 patients. Indications for surgery were instability (6 patients), chronic instability with secondary degenerative joint disease (6), osteoarthritis (6), inflammatory arthritis (7), and paralytic boutonniere (1). The technique uses the cup-and-cone method of(More)
BACKGROUND Liver stiffness measurement (LSM) using transient elastography is widely used in the management of patients with chronic liver disease. OBJECTIVES To examine the feasibility and reliability of LSM, and to identify patient and operator characteristics predictive of poorly reliable results. METHODS The present retrospective study investigated(More)
BACKGROUND Severe alcoholic hepatitis (AH) is associated with a substantial risk for short-term mortality. OBJECTIVES To identify prognostic factors and validate well-known prognostic models in a Canadian population of patients hospitalized for AH. METHODS In the present retrospective study, patients hospitalized for AH in Calgary, Alberta, between(More)
BACKGROUND Epidemiologic studies of alcoholic hepatitis (AH) have been hindered by the lack of a validated International Classification of Disease (ICD) coding algorithm for use with administrative data. Our objective was to validate coding algorithms for AH using a hospitalization database. METHODS The Hospital Discharge Abstract Database (DAD) was used(More)
The influence of growth on the extent of heterosis for juvenile body weight and gonad development was studied in a diallel cross among two lines of Japanese quail differing in adult body size. A total of 1,096 birds (563 males and 533 females) was slaughtered between 25 and 49 days of age. Reciprocal cross differences were non-significant. Heterosis showed(More)
