Hemoptysis during sexual intercourse. Unusual manifestation of coronary artery disease.

Sexual activity increases physiologic demands on the cardiovascular system. A patient with stable angina pectoris experienced recurrent bouts of hemoptysis caused by left ventricular failure that occurred only during sexual activity. Severe atherosclerotic coronary vascular disease was confirmed by cardiac catheterization. The patient underwent successful coronary artery bypass grafting; nine months after surgery, he is sexually active and symptom-free.

Effect of massage on serum level of beta-endorphin and beta-lipotropin in healthy adults.

We conducted this study to evaluate the effect of massage on the levels of endogenous opiates in peripheral venous blood. The results were based on findings from 21 healthy, adult volunteers. After separation by sex, the volunteers were assigned randomly to either the Control Group (n = 11) that rested but received no massage or the Experimental Group (n = 10) that received a 30-minute complete back massage. We found no significant pretreatment or posttreatment difference in blood beta-endorphin or beta-lipotropin levels between the groups. The results indicate that massage did not change significantly the measured serum levels of beta-endorphin or beta-lipotropin in our healthy subjects without pain. A follow-up study using patients experiencing acute or chronic back pain is recommended. Massage is used routinely in the treatment of such patients, and endogenous opiates are recognized as a possible mechanism for pain relief.

Natural history of fever following seizure.

Generalized tonic-clonic seizure, like vigorous exercise, can cause a rise in body temperature. To describe the course of fever following a generalized seizure, the temperature curves of 93 hospitalized postictal patients were reviewed retrospectively. Forty patients (43%) had an elevation of body temperature above 37.8 degrees C (100 degrees F). No underlying infectious illness was identified in two thirds of the febrile patients, 89% of whom had become and remained afebrile by 48 hours. One third of the febrile patients who did have an infection were still febrile after 48 hours. This finding may help clinicians determine the timing of appropriate tests to rule out infections during the postictal period.

Repeated gonorrhea: an analysis of importance and risk factors.

This study was designed to assess the epidemiological importance of repeated infections due to Neisseria gonorrhoeae and to analyze variables potentially associated with repeated gonorrhea. The retrospective analysis was of 7,347 patients seen during one year, and the prospective study was of a stratified randomly selected sample of 429 patients. The 492 retrospectively identified repeaters constituted 0.06% of the county population and 6.7% of the clinic population. The 492 repeaters had 21.6% of the cases of gonorrhea reported from the county and 29.4% of the cases reported from the clinic. The repeaters tended to be younger than those without repeated infection (P less than 0.001), male (62%), black (81.7%), and residents of areas of lower socioeconomic status than those who were not repeaters (P less than 0.001). Most repeaters (73.5%) had not graduated from high school. Repeaters did not have significantly greater numbers of sex partners (P greater than 0.05) or greater exposure to prostitutes or clients than those who did not have repeated infections and less frequently had sexual contact while symptomatic. Intensive follow-up of the small number of high-risk repeaters and their contacts could result in a major reduction in the number of reported cases of gonorrhea.

Experimental validation of self-instructional modules on the topic of donor phlebotomy.

This validation study investigated the effectiveness of an instructional unit on the topic of donor phlebotomy. The unit consisting of 3 modules based on a videotape and 3 booklets covered (1) donor selection, (2) donor arm preparation, (3) donor phlebotomy. A separate-sample pretest-post-test design was used. All 3 modules were found to be instructionally effective as measured by objective referenced tests. Student appraisal data also was collected for the purpose of revising and improving these materials.
