The influence of exercise-induced temperature elevations on the auditory brain-stem response (ABR).

The influence of exercise on the auditory brain-stem response (ABR) was examined in 16 healthy volunteers (8 female and 8 male). Ipsilateral ABR recordings were obtained before and after exercise on a bicycle ergonometer. The rise of body temperature so generated was 0.5-2.1 degrees C (mean, 1.3 degrees C) as measured in the contralateral external auditory meatus. Latencies of waves III and V (but not wave I) were found to be significantly lower immediately post-exercise (P less than 0.01). The temperature relations of the latency of wave V are described by the regression equation: Latency (ms) = 11.06-0.146 x temp. (degrees C). (The effects on amplitude were not significant, nor were male/female differences.) It is suggested that exercise hyperthermia could be an appropriate model for the evaluation of the ABR in fever.

Arthroscopic decompression of meniscal cysts: report of 14 cases.

Meniscal cysts are a painful disorder of the knee affecting young to middle-aged adults. The recommended treatment has been total meniscectomy. With the widespread use of arthroscopic surgery there has been a trend to a more conservative management of meniscal pathology in general. We treated 14 patients with meniscal cysts (13 lateral, one medial) by partial arthroscopic meniscectomy and decompression. At a mean follow-up of 19 months, results were satisfactory in 12 patients; there was one recurrence and one patient had reinjured his knee. We concluded that arthroscopic decompression of meniscal cysts is a promising form of treatment.

Assessing dangerousness in criminals.

This article formulates a definition of the term dangerousness, indicates why the commission of dangerous offences cannot be reliably predicted, and then reviews the several factors which have been or might be used by those who have to make decisions about dangerousness in criminals. Its suggests that these factors are useful insofar as they help to illuminate the individual's capacity to feel sympathy and to learn by experience. Since the accuracy of prediction varies inversely with time, the maintenance of personal relationships and good communication seems the inescapable requirement in the management of potentially dangerous criminals.

Effects of ambulance transport in critically ill patients.

Two groups of critically ill patients were transferred by ambulance from other hospitals to a central intensive therapy unit. The effect of transport was reviewed retrospectively in 46 patients and prospectively in 20 patients. Of the 46 patients reviewed retrospectively six became hypotensive, six became hypertensive, and seven developed delayed hypotension. One patient developed fits and six out of 13 patients had a rise in arterial PCO-2 of 1-6-4-1 kPa (12-31 mm Hg). Of the 20 patients reviewed prospectively, one patient became hypertensive due to overtransfusion, one had a fit, but none became hypotensive. Three out of four cases of delayed hypotension were related to starting intermittent positive pressure ventilation. Arterial PCO-2 fell in one patient and arterial PCO-2 rose in two, each change being related to changed oxygen therapy or narcotics. There were no changes in other cardiovascular or respiratory indices, body temperature, or urine production. Earlier transfer, resuscitation before transfer, continuing medical care during the journey, and hence a slower smoother journey seemed to be important factors in the management of these patients. Our findings, may have important implications in the future regional organization of the care of critically ill patients.
