Defibrination syndrome with defective thrombinfibrinogen reaction reversible by protamine.

A patient with the obstetric defibrination syndrome successfully treated with human fibrinogen is described. The blood not only contained low levels of fibrinogen capable of clotting but also contained an inhibitor of the thrombin-fibrinogen reaction. This was neutralized in vitro with protamine but it was not heparin. Neither abnormality was detected by a latex agglutination test for plasma fibrinogen. The use of this test does not therefore exclude the diagnosis of the defibrination syndrome.

Continuing professional education and interacting variables affecting behavioral change in practice: instrument development and administration.

BACKGROUND: Instruments were developed to measure variables identified by Cervero that evaluate the complex processes and effectiveness of continuing professional education. METHOD: Content validity was established with a panel of experts. Four studies were conducted to determine reliability. Data were merged to conduct factor analysis. RESULTS: Reliability was confirmed across studies using Cronbach's alpha. Stability was confirmed in a test-retest study. Factor analysis confirmed instrument items measure the concepts of Cervero's Model. CONCLUSION: The reliable and valid instruments may be useful for continuing education and staff development nurses to measure the effectiveness of education on behavioral change in practice.

Maxillo-facial surgical approach: an introduction and review of mandibular advancement.

Patients afflicted with obstructive hypersomnia sleep apnea (HSA) have been treated traditionally with permanent tracheostomy. More recently, an association between HSA and mandibular retrognathism has been noted. Several centers have reported rapid reversal of HSA symptoms in retrognathic patients after mandibular advancement. Their experiences are outlined; the anatomy and pathophysiology leading to obstructive HSA are reviewed, and the recommendations for evaluation and patient management are discussed.

Guidelines for measurement of blood pressure, follow-up, and lifestyle counselling. Canadian Coalition for High Blood Pressure Prevention and Control.

As part of the Coalition's mandate to promote the prevention and control of high blood pressure in Canada, an interdisciplinary Workgroup was established to review and update the existing standards (1987) for blood pressure measurement and referral guidelines. The intent was to prepare a scientifically based document which contained practical guidelines for the measurement of blood pressure and criteria for follow-up, and one which promoted the concept of cardiovascular health in the assessment and interpretation of blood pressure readings. These guidelines were primarily developed to assist primary health care providers and/or clinicians to assess, monitor, counsel, refer, and develop treatment plans for adults-at-risk for high blood pressure or those with the confirmed diagnosis of hypertension. Readers are referred to The Canadian Hypertension Society Consensus Conference series (Canadian Medical Association Journal 1993) for specific guidelines on the evaluation, diagnosis, and treatment of hypertension. The document is divided into three sections: 1. Measurement of blood pressure 2. Criteria for follow-up 3. Guidelines for lifestyle counselling Each section cites the references used in developing the guidelines and where relevant, identifies other resources which can be used in clinical practice.

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 pharmacologic management of hypertension.

Adherence to pharmacologic therapy of hypertension is low (in the range of 50-70%) and has important implications both for blood pressure control and cardiovascular complications. Based on a review of the literature using the levels of evidence grading technique, determinants of adherence to the pharmacologic therapy of hypertension have been assessed. Additionally, interventions to improve compliance were evaluated. Patient-centred, health care provider-centred and drug-specific factors have all been shown to affect adherence rates. We conclude that the extent of adherence to pharmacologic therapy is modifiable. Measurable improvements in adherence can be obtained from simplified medication regimens and a combination of behaviour strategies, including the tailoring of pill-taking to patients' daily habits and rituals, the advocacy of self-monitoring of pills and blood pressure, and the institution of reward systems.
