Fifty consecutive coronary artery bypass grafting (Group I) and 50 single valve replacement (Group II) procedures were compared with 50 coronary artery bypass grafting with valve replacement (Group III) procedures and 50 multi-valve procedures (Group IV) to determine the frequency of neurological complications after cardiopulmonary bypass (CPB). The possible risks and aetiological implications were studied. The overall surgical mortality rate was 7.5%, being 0%, 4%, 6% and 20%, respectively for the different groups. ⋯ Three patients had peripheral nerve paresis. The age of the patients and the duration of the CPB operation were not factors in the risk of neurological complications. Previous neurological events seemed to increase the frequency of postoperative neurological disorders, whereas combined procedures were no more dangerous in this respect.

The clinical course and outcome of 64 burned patients treated in the intensive care unit were analysed in order to find indicators for prognosis. Total burn area varied from 7 to 90% of body surface area. 17 patients (27%) died. ⋯ By means of a logistic model factors were obtained which proved most significant for prognosis; these were the age of the patient, arterial pH and serum protein concentration at the beginning of the treatment. The results suggest that the extent of the burned area is not the only factor affecting the outcome of the patient.

Case Reports Comparative Study
Anaesthesia for patients with multiple sclerosis.
The types of anaesthesia administered to 56 multiple sclerosis patients undergoing surgery in the different departments of the Helsinki University Central Hospital (HUCH) during a ten year period from 1973 to 1982 were studied. The perioperative and postoperative events were analyzed in relation to the method of anaesthesia. ⋯ In four patients who were given regional anaesthesia (2 spinal, 3 epidural) marked by hypotension, quite resistant to intravenous vasopressor treatment was observed. No deterioration of the multiple sclerosis was noted postoperatively which could be related to the anaesthesia.

Comparative Study
The predictive value of three diagnostic procedures in the evaluation of palpable breast tumours.
In a prospective study of 200 palpable breast tumours of 200 women, the diagnostic specificity and sensitivity of clinical examination, mammography, and fine needle aspiration were compared, alone and in combinations. All tumours were excised and examined histologically, and 38 were malignant. The diagnostic sensitivity of clinical examination was high, 98% (91-99), whereas the specificity was rather low, 48% (36-60). ⋯ It is concluded that the possibility of distinguishing between malignant and benign palpable breast tumours is not increased by adding mammography and/or fine needle aspiration, but the discovery of two non-palpable malignant tumours by mammography underscores the importance of this method in disclosing subclinical malignant lesions. The study disclosed a statistical possibility of overlooking a few malignant tumours when using these three procedures. Therefore, we advise that all palpable breast tumours should be excised.

This review includes a brief discussion of the indications and pitfalls of regional anaesthetic techniques commonly used during parturition. Emphasis is given to the physiological changes of pregnancy and the potential effects on the fetus. The criteria for the choice of local anaesthetic are also presented.
