Why people drink has been the subject of much research, however, why people do not drink has been largely neglected. The aim of the present study was to develop a Motives for Abstaining from Alcohol Questionnaire (MAAQ) based on Cox and Klinger's [Journal of Abnormal Psychology 97 (1988) 168; Why people drink (1990) 291] motivational model of alcohol use to(More)
BACKGROUND Avalanches are a significant cause of winter recreational fatalities in mountain regions. The purpose of this study was to determine the relative contributions of trauma and asphyxia to avalanche deaths. METHODS We reviewed all avalanche fatalities between 1984 and 2005 that had been investigated by the offices of the British Columbia Coroners(More)
BACKGROUND Asthma mortality rates have increased in Canada and worldwide. Within Canada, the highest rates were seen in the prairie provinces. OBJECTIVE The objective was to determine risk factors for fatal asthma by comparing those who died of an acute exacerbation with those who attended an emergency department for treatment of asthma. METHODS The(More)
To evaluate risk factors for asthma mortality, an unmatched case-control study was undertaken in the Canadian prairie provinces of Alberta, Saskatchewan, and Manitoba. Those between the ages of 5 and 50 (inclusive) who died from an acute exacerbation of asthma were compared to a control group of people with asthma from the same geographical areas who were(More)
Sera were obtained postmortem from 55 subjects classified into three groups; death due to asthma (FA, n = 21), asthmatic but death not due to asthma (NFA, n = 24) and a nonasthmatic control group (NAC, n = 10). A full autopsy was performed on all cases and a medical history, including details of allergies, was obtained by questionnaire from the next of kin.(More)
A submucosal network of elastic fibers in a collagen and myofibroblast matrix form discrete longitudinal bundles (LB) in the bronchial tree. The LB may affect airway function by altering the mechanical properties of the airway wall or by changing the folding behavior of the airway mucosa. The area and number of LB were quantified from 12 cases each of fatal(More)
To identify factors that may contribute to asthma mortality, 108 acute asthma deaths were reviewed. Information was obtained from medical records, next-of-kin, and autopsy records. The fatal asthmatic was characterized by early-onset asthma, severe disease requiring systemic corticosteroids, and prior hospitalization. Risk factors associated with gender,(More)
STUDY OBJECTIVES The bronchial arteries supply systemic blood to the airways, tracheobronchial lymph nodes, and nerves. Their structure has not been studied in patients with asthma. DESIGN Case-control study of pathologic changes of bronchial arteries in asthma. PARTICIPANTS AND METHODS Postmortem lungs were examined from three case groups: (1) fatal(More)
BACKGROUND Asthma can usually be controlled through allergen avoidance and/or appropriate medication. An emergency department visit for an acute exacerbation of asthma often represents a breakdown in asthma management. Emergency department treatment results in significant health care expenditures and reflects a compromised quality of life. OBJECTIVES To(More)
This paper presents an unusual form of sexual (masturbatory) activity and brings this unusual cause of death to wider medical attention and understanding. All 19 cases of autoerotic asphyxial death that occurred between 1978 and 1989 in the province of Alberta, Canada were reviewed. The fatal victim of autoerotic asphyxia is typically a single male aged 15(More)
