Acute Headaches; Presenting Symptoms And Diagnostic Rules To Identify Patients With Tension And Migraine Headache , Paula Diehr Jan 1981

Acute Headaches; Presenting Symptoms And Diagnostic Rules To Identify Patients With Tension And Migraine Headache , Paula Diehr

Paula Diehr

Headache is the ninth most common cause of physician visits, but data on acute headaches have not been collected in a standardized manner and have not been analyzed in a multivariate fashion. We report on 726 patients presenting with acute headaches, which were diagnosed as tension (38%), migraine (25%), no diagnosis (30%), and other (6%). The prevalence of 32 signs and symptoms is shown for each group. Four of these findings were significant predictors of tension headache, and 19 were significant predictors of migraine headache (p<.05). Several diagnostic rules are developed which classify nearly 90% of the headaches correctly, using only three to seven of the findings. On a new set of patients the classification was correct over 80% of the time. It is suggested that most acute headaches could be diagnosed over the telephone or by midlevel providers, which would provide substantial cost savings.

Adaptative Alteration In Phospholipid Composition Of Plasma Membranes From A Somatic Cell Mutant Defective In The Regulation Of Cholesterol Biosynthesis, Michael Sinensky Jan 1980

Adaptative Alteration In Phospholipid Composition Of Plasma Membranes From A Somatic Cell Mutant Defective In The Regulation Of Cholesterol Biosynthesis, Michael Sinensky

Michael Sinensky

A somatic cell mutant (CR1) of a Chinese hamster ovary cell (CHO-K1) which has previously been shown to be defective in the regulation of cholesterol biosynthesis accumulates more cholesterol than the parental cell line in plasma membranes. Although such an increase in membrane cholesterol should lead to an increase in the order parameter of these membranes, as measured with an electron spin resonance spin probe, the order parameters of mutant and wild-type plasma membranes are identical--apparently because of an adaptive alteration in membrane phospholipid composition. The phospholipid compositions of mutant and wild-type cell plasma membranes are compared and the mutant …

Increased Access To Medical Care: The Impact On Health, Paula Diehr Oct 1979

Increased Access To Medical Care: The Impact On Health, Paula Diehr

Paula Diehr

Many federally financed programs have been launched to improve the access of the poor to medical care, under the assumption that this will improve their health. The effectiveness of these programs, however, has generally been measured by increased utilization rather than by improved health. The few studies which have considered health status have shown small or negative effects. Here, data are presented from a project which provided fully prepaid care to near poor families through existing sources in the community. A group of 748 enrollees was found to report worse health on four of five health indicators after one year …

Rudolf Kaehr

6-page telegram from Paul Feyerabend (London) to Rolf Kaehr (Westberlin) Telegram 1 I am ill. Please let the seminar continue in my absence. Inform Prof Landmann and Prof Huebner, cancel the hotel reservation and read the following final message to my class on tuesday 1pm: I am sorry that I cannot give what Telegram 2 would have been my last lecture to you. In this lecture I would have elaborated on Verons argument and would have tried to show that it also excludes consience, self expression, identification. Turning back to the empiricist methodology and demand for theoretical unification I would …
