Changes in the proportion of penicillin-non-susceptible Streptococcus pneumoniae (PNSP) isolates during an intervention programme were evaluated by phenotypic analysis of all initial isolates with penicillin MIC > or =0.5 microg/ml (n=1248) collected 1995-2004. During the study period, the proportion of such isolates was fairly constant (12-19%), and there was no statistically significant variation in the proportion of total PNSP cases (MIC > or =0.12 microg/ml) or PNSP with MIC > or =0.5 microg/ml, with the exception of an increase in 2004. Analysis restricted to clinical cases revealed no statistically significant changes. 23 different serogroups were found, and serogroup 9 isolates accounted for almost half of the PNSP cases. Only minor changes in phenotypic characteristics occurred in the other serogroups, which indicates that the increase in PNSP in 2004 was not due to import of a new resistant clone. Antibiotic consumption is considered to be an important risk factor for penicillin resistance in S. pneumoniae. After initiation of the intervention programme in Malmö, overall prescribing of antibiotics decreased 28%, and the reduction was even greater among children (52%). In conclusion, the proportion of PNSP isolates in Malmö has remained stable, despite the intervention programme and decreased consumption of antibiotics.
Although most occupational and physical therapists in an acute burn care setting use similar therapy practices, the time frames at which these therapeutic interventions are carried out vary according to the burn centers' practices. The purpose of this survey was to investigate current trends in burn rehabilitation and compare the results with a similar survey performed in 1994. The survey was designed in a similar fashion to the 1994 survey to ascertain common trends in burn rehabilitation. The survey was sent to 100 randomly selected burn care facilities throughout the United States and Canada. Content included rehabilitation interventions, including evaluation, positioning, splinting, active range of motion, passive range of motion, ambulation, as well as the cross-training of therapists. Significant increases in the percentages of burn centers initiating common therapy practices were found. Positioning (41% increase), active range of motion (48% increase), passive range of motion (52% increase), and ambulation (29% increase) were all found to have increases in the number of burn centers employing these practices in the same time frame. Overall comparison from 1994 to 2006 shows that common therapy techniques are being initiated earlier in the patient's acute burn stay. These results are consistent with recent medical trends of earlier acute discharges and more focus on outpatient rehabilitation.
The prevalence of dementia is placing an increased burden on specialists.
Canadian neurologists responded to a structured questionnaire to assess reasons for referral and services provided as well as to compare the neurologists' perceptions of their practice characteristics against cases seen over a 3-month period.
The audit confirmed the participants' perception that family practitioners are the main referral source (358/453, 79%). Sixty-two percent of patients had undergone clinical investigation for dementia prior to being seen by the neurologist; 39% (177/453) were on pharmacotherapy at the time of referral, 68% were initiated on pharmacotherapy by the neurologist. A fifth of the referrals did not meet clinical criteria for dementia, which may be directly related to the prevalence of prior workup that did not include mental status testing.
Neurologists currently treat patients referred for dementia who may already have been adequately evaluated and treated by primary care providers.

To collect national baseline information on asthma management practices by physicians, and to compare these practices with the recommendations of the Canadian Asthma Consensus Conference ('the guidelines').
Cross-sectional survey of representative samples of physicians in Canada in late 1996 and early 1997.
Five specialty types of physicians who manage asthma patients: respirology, pediatrics, internal medicine, allergy and clinical immunology, and general practice and family medicine. Stratified sampling by province and specialty was used to select physicians for the study. Weighting was used in the analysis to generalize the results to the national level for the five specialty groups of physicians.
Mailed questionnaire, self-administered by the respondent; three mailings of the questionnaires were used to increase the response rate.
The frequency with which each of the five specialty types chose specific asthma management choices was determined, using weighted percentages representative of the specialty groups on a national basis. ANOVA determined the statistically significant differences among the five specialties in choosing particular asthma management actions. Then, logistic regression was used to calculate the odds ratios showing an association between the characteristics of the physician respondents and specific asthma management choices that they made in the survey.
The data analysis demonstrated significant variations among physicians in asthma management practices, according to specialty type and other characteristics. The initial report was released in April 1998, and manuscripts for journal submissions are being prepared.
To revise and expand the 1996 Osteoporosis Society of Canada clinical practice guidelines for the management of osteoporosis, incorporating recent advances in diagnosis, prevention and management of osteoporosis, and to identify and assess the evidence supporting the recommendations.
All aspects of osteoporosis care and its fracture complications - including classification, diagnosis, management and methods for screening, as well as prevention and reducing fracture risk - were reviewed, revised as required and expressed as a set of recommendations.
Strategies for identifying and evaluating those at high risk; the use of bone mineral density and biochemical markers in diagnosis and assessing response to management; recommendations regarding nutrition and physical activity; and the selection of pharmacologic therapy for the prevention and management of osteoporosis in men and women and for osteoporosis resulting from glucocorticoid treatment.
All recommendations were developed using a justifiable and reproducible process involving an explicit method for the evaluation and citation of supporting evidence.
All recommendations were reviewed by members of the Scientific Advisory Council of the Osteoporosis Society of Canada, an expert steering committee and others, including family physicians, dietitians, therapists and representatives of various medical specialties involved in osteoporosis care (geriatric medicine, rheumatology, endocrinology, obstetrics and gynecology, nephrology, radiology) as well as methodologists from across Canada.
Earlier diagnosis and prevention of fractures should decrease the medical, social and economic burdens of this disease.
This document outlines detailed recommendations pertaining to all aspects of osteoporosis. Strategies for identifying those at increased risk (i.e., those with at least one major or 2 minor risk factors) and screening with central dual-energy x-ray absorptiometry at age 65 years are recommended. Bisphosphonates and raloxifene are first-line therapies in the prevention and treatment of postmenopausal osteoporosis. Estrogen and progestin/progesterone is a first-line therapy in the prevention and a second-line therapy in the treatment of postmenopausal osteoporosis. Nasal calcitonin is a second-line therapy in the treatment of postmenopausal osteoporosis. Although not yet approved for use in Canada, hPTH(1-34) is expected to be a first-line treatment for postmenopausal women with severe osteoporosis. Ipriflavone, vitamin K and fluoride are not recommended. Bisphosphonates are the first-line therapy for the prevention and treatment of osteoporosis in patients requiring prolonged glucocorticoid therapy and for men with osteoporosis. Nasal or parenteral calcitonin is a first-line treatment for pain associated with acute vertebral fractures. Impact-type exercise and age-appropriate calcium and vitamin D intake are recommended for the prevention of osteoporosis.
All recommendations were graded according to the strength of the evidence; where the evidence was insufficient and recommendations were based on consensus opinion alone, this is indicated. These guidelines are viewed as a work in progress and will be updated periodically in response to advances in this field.
