A minimal prevalence study of diagnosed diabetes in Newfoundland and Labrador.

A two-stage random probability sampling survey of the medical charts of family physicians in Newfoundland and Labrador was done; the first stage sampled physicians randomly, in proportion to the 5 health districts of the province; the second stage took a quota sample of the physicians' charts. The survey revealed a total population minimal prevalence rate of diagnosed diabetics of 3.55% (95% confidence limits 2.55, 4.55). This rate is higher than that found in the only other provincial survey done in Canada (the Prince Edward Island survey). Of diagnosed diabetics, 40% were found to be using insulin. This proportion is higher than other rates in North America. The prevalence rate was slightly higher in males (3.7%) than in females (3.4%).

[Ultrasonography of the neonatal hip: state of the art and perspectives].

Since the first studies by Graf, medical interest for neonatal hip sonography (US) has grown, till the redefinition of the name itself of the pathologic condition, which has been recently renamed developmental dysplasia of the hip. After briefly reviewing our personal series of patients (18,388 hips studied from March, 1986, through June, 1995, with 2.81% positives according to Graf, 0.65% of them with subluxated hips), several issues are discussed relative to US of the neonatal hip in the study of dysplasia, namely: 1) technique, 2) measurements, 3) unstable hips, 4) screening, 5) protocols, 6) perspectives. Relative to the technique, Graf's method is currently the method of choice because it is easy to perform (single scanning) and repeatable, different from what other authors, particularly Novick and Harcke, suggested; they use a dynamic approach with more scans and different stress tests. Moreover, in Graf's technique, special attention is paid to the need for correct measurements, which phase was criticized by Couture who complained of its claimed complexity. Hip measurements are an important step in the study of this condition thanks to the information they yield the physician who can thus customize the therapy. The problem of the unstable hip and focal ligament laxity is discussed, which is hypothesized to be a possible cause of hip dysplasia misdiagnosis; according to Graf and Tönnis, this condition is related mostly to hormonal factors and has no actual clinical importance in the possible evolution to a pathologic condition. US of the neonatal hip must be set in a general screening program for newborns to be carried out by the 6th week of life to achieve optimal recovery in positive newborns, without limiting it to supposedly at risk groups. Moreover, the cost-benefit ratio of US screening is emphasized, provided that both medical staff and units are used correctly. A working diagnostic-therapeutic protocol is needed to plan standard epidemiologic guidelines for all physicians nationwide. Finally, we report on an initial study for new applications of US to the neonatal hip with an original computer software for automatic measurement of Wiberg's angle in the newborn, which might help predict the development of early juvenile coxarthrosis.

Adherence to management of high blood pressure: recommendations of the Canadian Coalition for High Blood Pressure Prevention and Control.

Adherence or compliance, in the context of medical treatment, refers to how well a patient follows and sticks to the management plan developed with her/his health care provider, which may include pharmacologic agents as well as changes in lifestyle. Adherence is of great concern in asymptomatic conditions such as hypertension, where lack of control may have serious ramifications including end organ damage and premature mortality. To address this issue, the Canadian Coalition for High Blood Pressure Prevention and Control established a national Advisory Committee on Adherence to the Management of High Blood Pressure. The Advisory Committee consisted of 11 members from different disciplines of health care providers. The Committee reviewed all evidences to date and drew up four practical recommendations with respect to patient, provider and environment. Based on Canadian Task Force on Periodic Health Examination's guidelines, all four recommendations can be classified as 'level C' with a quality of evidence of II.

Adherence to non-pharmacologic therapy for hypertension: problems and solutions.

The efficacy of a number of non-pharmacologic interventions in the therapy of primary hypertension has been firmly established. Most prominently, weight reduction, sodium restriction, and alcohol restriction have significant effects on lowering blood pressure. Increased physical activity contributes to management of hypertensive patients in a variety of ways: apart from having a direct impact on blood pressure level, it is an important supportive factor in a weight-reducing regime. The success in applying these non-pharmacologic measures in standard patient population is rather limited. A salient example is the lack of success in weight reduction. Reduction of sodium in the diet is somewhat more successful, however, the problem is that most of the salt intake is non-discretionary. Adherence to physical activity regimes is in the range of what has been observed in pharmacologic therapy. Research and experience in the past few years are providing a better understanding of the factors determining compliance with prescribed therapeutical regimes. Further research is needed to develop innovative strategies for providing efficacious non-pharmacologic measures to hypertensive patients.
