Modification of the mandibular ramus sagittal split osteotomy.

The sagittal split osteotomy of the mandibular ramus is a common procedure used in the correction of mandibular deformities. Modifications of the procedure will be presented for advancement and setback of the mandible. Major advantages of this technique include controlled splitting of the segments and predictable positional control of the proximal segment. The advantages and disadvantages of rigid skeletal stabilization are discussed, as well as application to the modified mandibular ramus sagittal split osteotomy.

The maxillary step osteotomy and Steinmann pin stabilization.

Use of the maxillary step osteotomy facilitates the transfer of information obtained by prediction tracing and model surgery to the patient at the time of surgery and allows for a well-visualized bone grafting area in cases of maxillary advancement. The use of Steinmann pin maxillary stabilization provides improved anteroposterior and vertical stabilization in indicated cases.

Myocardial infarction in diabetics.

The hospital mortality of acute myocardial infarction amongst 285 known diabetics treated in the last decade was 39.7 per cent at one month and had increased to 51 per cent at 12 months. Treatment in a coronary care unit during the acute stage had little effect on the mortality amongst patients on insulin, but was beneficial for patients whose diabetes had been controlled by oral hypoglycaemic drugs. Female patients on oral hypoglycaemic drugs had the highest mortality. When considering age, duration of diabetes and presence of retinopathy, acute myocardial infarction in diabetics controlled on oral therapy appeared to have a worse outcome than in patients on insulin. Independently of whether patients were on insulin or on oral hypoglycaemic drugs 12 months after the acute episode, only about half of them were still alive.

Cyanide self-poisoning.

Four cases of cyanide self-poisoning were admitted to one hospital over a period of two years. Two of the patients died. The diagnosis in the unconscious patient may be suggested by the finding of bradycardia and the absence of cyanosis (despite inadequate ventilation). The diagnosis can be confirmed in 5 to 10 minutes by a simple test on gastric aspirate, performed by the casualty officer. Cardiac pacing was used in two patients and may have a place in the supportive management of severe cases.

Quantitative study of infarcted myocardium in cardiogenic shock.

A post-mortem study of the heart was performed in 20 patients dying of cardiogenic shock. The extent of infarcted myocardium was defined by using a mitochondrial dehydrogenase stain nitro-BT which allowed macroscopical recognition of tissue death as early as 12 hours. Extensive myocardial injury was found to accompany cardiogenic shock predominantly affecting the left ventricle and the interventricular septum. Severe atheromatous involvement of the coronary arteries was noted.
