Case Reports[Neuroradiologic intervention in intracranial arteriovenous malformations].
23 patients with intracranial arteriovenous malformations and durafistulas were embolized. 13 underwent embolization with polyvinylalcohol and silk threads as the only means of therapy, while six were also operated on, and four received radiation after considerable reduction of the nidus had been achieved. No death or major complications occurred in these patients. The authors considered the embolization to be successful in all cases.

The position of a central venous catheter has to be controlled. As a supplement to radiography of the chest the position of the catheter tip can be documented by means of ECG. The ECG is recorded with the catheter tip functioning as one of the electrodes. ⋯ The position of the catheter tip correlates with the morphology of the P-wave. An ECG recording performed during insertion of the catheter can be used to achieve correct positioning of the catheter to start with and thereby reduce the frequency of having to replace wrongly positioned catheters. Intraoperatively the ECG recording is a practical method of achieving correct and extracardial placement of the catheter tip.

[Musculoskeletal disorders among employees in building and construction industry].
A questionnaire was distributed to 2,696 employees in the construction industry in order to determine the prevalence of subjectively experienced musculoskeletal strain in four regions of the body. A total of 40.3% of the employees had pain at the time of questioning. ⋯ We presume that more than 90% of these disorders are caused by factors in the working environment. The author concludes that it is important to continuously collect information on musculoskeletal disorders among workers, and analyze all the data systematically.

Case Reports[Deep accidental hypothermia with asystole. A successful treatment with heart-lung machine after prolonged cardiopulmonary resuscitation].
Extracorporeal circulation can be utilized successfully to rewarm accidental hypothermia victims. This paper describes a 51 year-old man who had been immersed in cold sea water for about 45 minutes. At the time of rescue his ECG was isoelectric. ⋯ After two hours of reperfusion the patient could be weaned from bypass supported by high-dose vasopressor infusion. He was extubated the following day. He was discharged after 12 days without any signs of permanent damage to organs.

Comparative Study[Accidental hypothermia. Risk factors in 29 patients with body temperature of 30 degrees C and below].
29 patients with a body temperature below 30 degrees C (mean 26.4 degrees C) were treated during the period 1982-88, both years inclusive. Eight patients were severely hypotensive (systolic blood pressure less than 60 mm Hg) and two had ventricular fibrillation on admission. Bradycardia (less than 60 beats per minute) was noted in ten patients. 12 patients were rewarmed by surface warming, 17 by extracorporeal circulation with femoral cannulation. 22 patients (76%) were discharged alive. ⋯ A patient cooled indoors had an odd risk of 10.6 of hospital mortality compared to one found outdoors. For the sake of convenience, in hospitals with the available resources rewarming by extracorporeal circulation may be used in patients with circulatory arrest, since this is the easiest way to control and support failing circulation. In all other cases carefully monitored surface rewarming should be used as this necessitates less use of hospital resources and produces equally good results.
