German versions of the DSM-IV adapted Composite International Diagnostic Interview were administered to a representative sample of 4075 individuals. Multivariate analyses were used to compare impairment, life satisfaction, and use of health care. A total of 803 of 407...

BACKGROUND Adherence to medication is low in specific populations who need chronic medication. However, adherence to medication is also of interest in a more general fashion, independent of specific populations or side effects of particular drugs. If clinicians and researchers expect patients to show close to full adherence, it is relevant to know how likely the achievement of this goal is. Pop...

This article examines British medical debates about cancer education in the 1950s, debates that reveal how those responsible for cancer control thought about the public and their relationship to it, and what they thought the new political economy of medicine introduced by the National Health Service would mean for that relationship. Opponents of education campaigns argued that such programs wou...

There is a widespread opinion among ecologists that ecology lacks general laws. In this paper the author argues that this opinion is mistaken. Taking the case of population dynamics, the author points out that there are several very general law-like propositions that provide the theoretical basis for most population dynamics models that were developed to address specific issues. Some of these f...

This paper extends the Lotka system of stable population equations to any population. The authors present this new general system and describe its duality with the recent Preston-Coale system. They derive these results by considering the calculus of change on the surface of population density defined over age and time. They show that analysis of this Lexis surface leads to all the known fund...

Epidemiological data in the general population on daytime napping are scarce (1-4). This paucity of information reflects a disinterest from epidemiologists probably due to such popular beliefs that napping is a benign lifestyle habit shared mostly by elderly persons or a cultural phenomenon encountered primarily in warm, southern climates. Numerous clinical studies, however, have explored the f...

Tuberculin testing as a part of case-finding programs and as an aid in differential diagnosis has become increasingly important in recent years. Formerly the test was little used because it was the general belief that all adults and the majority of children living in urban communities were infected with tubercle bacilli. Veeder and Johnston’ (1915), noted statements were frequent in medical and...

The Manning criteria were used to define irritable bowel syndrome. SETTING Urban population in Southampto...

BACKGROUND Although all jurisdictions in Canada offer annual influenza immunization to people at high risk of complications, only Ontario has provided universal annual immunization of healthy adults and children. Use of chemotherapy (amantidine, neuraminidase inhibitors) to prevent influenza varies among provinces. We sought to systematically review the evidence for the prevention of influenza ...
