This report describes a patient with primary hyperparathyroidism who became spontaneously normocalcaemic preoperatively. This was due to infarction in a parathyroid adenoma. Plasma parathormone (PTH) levels were monitored pre- and postoperatively.
An unusual elbow injury occurring as a result of a poorly executed breakfall in judo is recorded. The treatment, possible mechanism and outcome are described. The poor prognosis of severe lesions is emphasised with reference to current literature.
Methods of preventing karate injuries are discussed. These fall into three groups:--1. Prevention by control. 2. Prevention by using protective clothing. 3. Pre-fight medical examination. The results of the above methods in reducing the incidence of injury in karate competitions are described. After a follow up one year (1102 fights) it is concluded that the incidence and severity of karate injuries has been reduced significantly thus making the sport safer.
The light and electron microscopic appearance of mesenchymal and myoblastic tissue in the embryonic heart is described. The similarity in the morphological appearance of all mesenchymal cells is pointed out, whether they occur in atrioventricular cushion tissue, the ridge tissue of the bulbus, cordis, sub-epicardial tissue or in mesenchyme elsewhere in the embryo. Cells intermediate in their ultrastructure between mesenchymal cells and myoblasts are found. The significance of such cells is discussed and the suggestion made that their appearance is consistent with their representing stages in the differentiation of mesenchymal cells into myoblasts.
