[Hospital employees' knowledge about HIV disease. A study from 2 provincial hospitals].

The knowledge of and attitudes to HIV infection were investigated by means of questionnaires during the period 1.10.1988 to 30.4.1989 in two small Danish Hospitals. Two hundred and thirty two nurses, 147 nursing aids, 44 doctors, 25 laboratory workers and 22 midwives took part in the investigation. The overall response was 99% of the staff contacted. The questionnaires were anonymous and were completed immediately and without use of any sources of information. Poor knowledge was revealed concerning symptoms, sources of infection, precautions to avoid infection, high-risk groups and patients duty to provide information. In fact, none of the groups exceeded 66% correct answers on these subjects. A total of 70% of the whole group had been in contact with patients, whom they suspected to be HIV-positive. Every third individual had felt insecure regarding HIV at work. Incidents at work had caused 18 employees to be tested for HIV. Only about half had been instructed about HIV. A total of 73% expressed needs for further instruction about the disease. The investigation shows difference between the staff opinion of possible claims on the patients about tests and to the policy of the Danish Department of Health concerning voluntary testing.

Hearing loss among high school farm students.

To study the prevalence of hearing loss among teen-aged farm children in central Wisconsin, audiometric threshold testing of 872 vocational agriculture students was carried out over a three-year period. The results indicate an increased prevalence of hearing loss among students actively involved in farm work, as compared to their peers not involved in farm work. Findings also suggest that use of hearing protection may reduce the risk of hearing loss among students who work on the farm, although few students report the use of such devices. These data also suggest that the hearing loss often observed in adult farmers may begin in childhood.

Effect of alprenolol on mortality among patients with definite or suspected acute myocardial infarction. Preliminary results.

A double-blind study of alprenolol versus placebo was done in patients with definite or suspected myocardial infarction to show the effect of the drug on mortality-rate after a year of treatment in patients aged less than or equal to 65 and to study the tolerance of the drug by patients greater than 65 years of age. The dose given was 5--10 mg intravenously, followed by 200 mg twice a day, orally. Patients in whom beta-blockade was contraindicated were excluded. All deaths, side-effects, and dropouts were recorded. Of the 480 patients in the study, 238 patients received alprenolol and 242 placebo. During the year of follow-up 108 patients dropped out from the study. Mortality was not reduced in patients greater than 65 years of age. In those less than or equal to 65 years alprenolol significantly reduced mortality-rate (20% mortality in placebo group vs 9% in treated group). There was also a significant reduction in mortality-rate among those with definite infarction (28% in the placebo vs 15% in the treated group).

Angiofollicular lymph node hyperplasia.

One case of angiofollicular lymph node hyperplasia simulating a salivary gland tumour is presented. In a review of the literature containing some 220 cases, 29 cases in the neck were found. A survey of these 29 cases is given, and another two cases of special oto-rhino-laryngologic interest are mentioned. Furthermore, a description of the tumour and a brief discussion of aetiology and differential diagnosis are given.

beta-Cyclodextrin as an aid to peritoneal dialysis. Renal toxicity of beta-cyclodextrin in the rat.

A peritoneal dialysate containing beta-cyclodextrin has been shown to accelerate the removal of intravenously administered phenobarbital in rats. It was found that high concentrations of beta-cyclodextrin were toxic to the animals in the single exchange technique employed. The renal toxicity was estimated by measuring blood urea nitrogen values in the rats following oral and intraperitoneal administration of the cyclic amylose.
