In 4 out of 9711 (= 1:2400) patients, lactice acidosis due to biguanides was diagnosed. Serum lactate concentration averaged 18.2 mmol/l and the pH value 6.87. All patients showed signs of renal insufficiency and three had congestive heart disease. In addition to treatment with biguanides, other factors might have contributed to the lactice acidosis in these patients: prolonged fasting, severe dehydration due to persistent vomiting, acute bronchopneumonia, and acute pyelonephritis. On addmission, two patients were in shock and all patients were semi-conscious or comatose. All patients were treated with bicarbonate and glucose/insulin. One patient was hemodialysed. Two of our four patients died. Oour four patients are compared with 179 patients in the literature with respect to mortality and prognosis of lactic acidosis due to biguanides.

The role of surgery in the treatment of extracranial cerebrovascular disease is essentially a prophylactic one but it should be borne in mind that apart from preventing stroke, such procedures will or should eliminate symptoms. The authors believe that every patient suffering from cerebrovascular insufficiency should be thoroughly evaluated for extracranial cerebrovascular occlusive disease and that arteriograms should be performed on all patients who could be expected to be candidates for surgery. The various indications for surgery have been discussed. The authors believe that people who have severe bilateral disease and who are of an advanced age are probably in a higher risk group. They also believe that surgery should not be offered to people who have a complete stroke and who are in semi-coma or coma, no matter how rapidly they may be transferred to the operating theatre. The authors firmly believe that intra-operative E.E.G. monitoring is an important adjunct to the safe surgical treatment of lesions of the carotid bifurcation, not only to indicate when shunting is necessary but also to indicate how well that shunt is functioning. In spite of the frequent presence of associated heart disease, hypertension and other vascular lesions, operation can be offered with confidence to suitable candidates. Elimination of symptoms can be expected in over 90% of cases. Only one patient has suffered a stroke since leaving hospital and this occurred because of occlusion in his internal carotid artery which was not operated on. Apart from patient selection, the factors which have contributed to the authors' low morbidity and mortality have been the use of intra-operative E.E.G. monitoring, intra-operative heparinisation and the availability of excellent angiographic studies.

Eleven cases of spontaneous hypoglycaemia in congestive heart failure in adults are reported. There were 5 males and 6 females, aged from 15 to 65 years (mean, 44 years). Blood sugar ranged from 2 to 42 mg/100 ml (mean 21 mg/100 ml). Six patients were in coma on admittance, 1 was confused, and 4 were conscious. The underlying condition was rheumatic valvular heart disease (3), chronic obstructive lung disease (4), cornonary heart disease (3) and cardiomyopathy (1). Five of the 11 patients died. The mechanism of hypoglycaemia is discussed and thought to be a combination of factors such as liver dysfunction, low calorie intake, malabsorption, and increased glusose utilization by ischaemic tissues, including the heart. It is recommended that in patients with congestive heart failure presenting with coma or confusion, blood sugar should be checked for possible hypoglycaemia.

One hundred seventeen patients undergoing cardiac operations over a two-year period were studied. Electroencephalograms were recorded preoperatively, in the recovery room (up to 12 hours following operation), 24 hours later, and further as required. Operative and anesthesia data were correlated with EEG findings. All patients had normal EEGs preoperatively. This unusual occurrence may largely reflect the absence of congenital heart disease and the small number of valvular lesions in our patients. Prognosis was not significantly influenced by age. Bypass time appeared directly related to outcome by group but not individually. Hypotension prior to pumping occurred most often and mean blood loss was greatest in the patients who had abnormal EEGs in the recovery room with progressively worsening patterns until death. In the recovery room many patients were awake, while others were either drowsy, lethargic, or asleep. Some were comatose. The level of consciousness was not as prognostic as was the EEG. The pattern of EEGs in the first few postoperative days is more important than any single record by itself. All those who showed progressive deterioration in the first two or three days died shortly thereafter.

Thyroid storm is a rapid decompensation of severe hyperthyroidism which can best be described by the three criteria of hyperthermia, tachycardia and altered mental state with severe agitation. There has to be a precipitating factor such as infection, iodine contamination, surgery or even I-131 treatment. Severe hyperthyroidism not fulfilling the criteria of thyroid storm can also be an indication for emergency treatment, particularly in the elderly with heart disease. Suppressed serum TSH and elevated free T4 levels are essential to confirm the diagnosis. When rapidly available, radioiodine uptake of the thyroid can be useful. Therapy aims at rapidly reducing the active circulating hormone pool, hypermetabolic state, tachycardia, and finally hormone synthesis. Thyroid secretion can be blocked by ioipanoic acid or ipodate while hypermetabolic state can be reduced with beta-blockers or calcium channel-blockers. Treatment of hyperthyroidism in patients with iodine contamination is a real therapeutic challenge. Myxoedema coma, a complication of severe hypothyroidism, is defined by hypothermia (rectal temperature less than 36 degrees C), bradycardia, slow mentation, precipitating factor such as infection or drug overdose, and increased serum creatine phosphokinase levels. Diagnosis of severe hypothyroidism should be confirmed by serum measurements of TSH and free T4. Treatment consists of general supporting measures including rewarming, correction of serum electrolyte disturbances, and adequate alimentation. Thyroid hormone treatment should initially be aggressive using either 300-400 micrograms of T4 or 20-40 micrograms of T3 intravenously. Cortisone therapy may be added. Patients should be under close monitoring as arrhythmias and myocardial infarction are frequent complications of myxoedema coma and/or its treatment with thyroid hormones.

A 10-year-old boy with idiopathic scoliosis presented with exertional dyspnea, lower leg edema since two weeks prior to admission. Physical examination revealed neck venous engorgement, moist rales, mild hepatomegaly, ascites and lower leg edema in addition to the scoliosis. Chest x-ray films showed cardiomegaly, pulmonary congestion and pneumonic infiltration of both lower lobes with bilateral pleural effusion. Electrocardiograms showed right axis deviation and right atrial hypertrophy. Two-dimensional echocardiography revealed dilatation of the right heart chambers and pulmonary artery. He was treated initially with mechanical ventilation, antibiotics, bronchodilators, diuretics, vasodilators, and digoxin with improvement. Unfortunately the patient became comatose after an episode of cardiopulmonary arrest. He did not recover from this tragedy and was discharged against medical advice in comatose state. Scoliosis may be complicated with pneumonia and cor pulmonale in children. Early surgical correction of the scoliosis may prevent the development of cor pulmonale. Combined medical and surgical managements should be carried out aiming at scoliotic heart disease.

Nine hundred ninety-four patients were enrolled in a field trial in which ambulance crews were randomly assigned to use simultaneous compression-ventilation (SC-V) CPR or conventional CPR procedures in the prehospital setting. Survival to hospital admission and to discharge was superior in the conventional CPR group vs. the experimental group (p less than .01). In a subset of adult cases whose causes of arrest were nontraumatic, survivor rates still favored the conventional CPR group: 33.5% of 337 vs. 22.5% of 365 (p less than .001). In limited cases where cardiac arrest was due to other heart disease, was vascular in origin or secondary to other natural diseases or from hypertensive cardiovascular disease, or when ECG on arrival was an agonal rhythm, survival was better (but not statistically significantly) in the experimental group. There were no statistically significant differences in the Glasgow coma scores between surviving patients in either group at 24 h post-hospital admission or discharge. It is concluded that survival in the SC-V CPR group was lower, likely reflecting a deleterious effect of the experimental technique of resuscitation. Also noted was that 14% of the control patients and 6% of the experimental patients survived with manual CPR alone.

Cerebrovascular risk factors, characteristics of the lesion (ischaemia or haemorrhage in the carotid or vertebro-basilar area) and mortality in the acute phase were studied in 503 patients admitted for first stroke. Seventy-five per cent of the patients had an ischaemic lesion and 25% a hemorrhagic one. Most of the ischaemic lesions occurred in patients aged 71-80 years, while haemorrhagic strokes hit subjects aged 61-70 years. Hypertension favors haemorrhage and heart disease and the older age favors ischaemia. Coma at onset negatively influences prognosis; mortality is more frequent among older patients, subjects in coma or with haemorrhagic lesions. Twelve per cent of the patients died in the first three weeks post-onset.

Isolated communities, such as those in the Highlands and Islands of Scotland have a dietary pattern and lifestyle which may differ from the rest of the country. We have studied the diets of 118 Orkney Islanders (78 women, 40 men) over 2 non-consecutive weeks, using a semi-weighed methodology. 'High tea', soups, fish, potatoes and bakery goods were features of the traditional dietary pattern. Fresh fruit and vegetable tended to be low, and intakes of vitamin C and, to a lesser extent, dietary fibre, were low in relation to energy. Energy intakes of men were consistent with an active lifestyle, while fat provided 42 per cent of the energy from food. The implications of these findings are discussed in relation to the COMA recommendations and the prevalence of heart disease in this region of Britain.
