Utilization of a freestanding emergency center by patients with and without private physicians.

We assessed the impact of a freestanding emergency center (FEC) on alternative sources of care for minor illness and injury by comparing patients who named a personal physician with those who did not, with regard to time of arrival and type of complaint (injury vs illness). Of 932 patients attending an Akron, Ohio, FEC during the study period, 71% named a primary care physician. These patients came proportionately more often with injury than did patients without a physician, and also presented more frequently with illness at times when their physicians were typically unavailable. By contrast, there was no distinction between the two groups with respect to time of arrival for treatment of injury. We concluded that the FEC may compete largely with the hospital emergency department in the treatment of patients with minor injury. In the case of patients with illness, the FEC vies with both the emergency department and the private physician.

Myocardial infarction following electrical injury.

Reported is a case of myocardial infarction following electrical injury in a previously healthy 57-year-old man. After coming into contact with high tension electrical current, the patient noted chest pain and electrical burns to his extremities. An electrocardiographic diagnosis of inferior wall myocardial infarction was made in the emergency department and was later substantiated by cardiac enzyme and angiographic studies. Although myocardial infarction following electrical injury has rarely been reported in the literature, most cases of severe electrical injury probably warrant cardiac monitoring.

Induced ovulation and conception in locating sows.

Fifty lactating sows were injected with 1,500 IU pregnant mare serum gonadotrophin (PMSG) at an average of 25 days postpartum. Twenty-four of these sows received prostaglandin F2 alpha (PGF2 alpha) 24 hr prior to PMSG. Ninety-six hours after the PMSG injection, 1,000 IU of human chorionic gonadotrophin (HCG) were injected. Artificial insemination was performed at 24 and 36 to 42 hr post-HCG. The PMSG/HCG treatment resulted in pregnancy in 17 of 20 sows slaughtered from 34 to 43 days postbreeding and in 23 of 30 sows allowed to complete gestation. Mean numbers of corpora lutea (33) and viable embryos (15) were counted at slaughter. Litter sizes were averaged (11) for those sows allowed to farrow. Treatment with PGF2 alpha prior to PMSG injection had no effect on conception rates, number of corpora lutea, number of embryos or litter size in the lactating sows. In a second experiment, the same hormone treatments were administered to lactating sows beginning on day 5, 10, 15 or 20 postpartum. Pregnancy rates were 0/10, 2/10, 8/10 and 6/10, respectively (P less than .05, chi-square). At slaughter (30 to 40 days postbreeding), corpora lutea and embryo numbers recorded from pregnant sows were 23.0, 9.5; 31.5, 15.3, and 28.0, 18.8, respectively, for the sows in the day 10, day 15 and day 20 groups. In a third experiment, sows were given PMSG-HCG as previously described on either day 5 (five sows) or day 10 (14 sows) postpartum. Laparotomy of these sows 2 to 5 days postbreeding revealed minimal ovarian responsiveness at day 5, but 43% of the animals responded with multiple ovulations at day 10. The low pregnancy rate seen at day 10 in Exp. 2 may reflect embryonic mortality due to unfavorable uterine environment. We conclude that the PMSG/HCG treatment followed by timed artificial insemination of lactating sows will induce ovulation and coneption as early as 15 days postfarrowing. Pregnancy is thus concurrent with lactation, eliminating the need for early weaning and reducing the interval between successive farrowings.
