1. Two fatal cases of toxoplasmic encephalitis are descriptionbed. The first-a classical example of the congenital type-occurred in a European infant from Northern Rhodesia; the second-an example of the fulminating encephalomalacic type-occurred in a European child living on the Witwatersrand. 2. Attention is drawn briefly to the varied clinical forms which have been recorded in adults, especially the types which simulate tick typhus.
The normal bowel has tone and propulsive as well as segmental movements, the latter heard on auscultation as first- and second-degree bowel sounds respectively. Various factors inhibit the bowel and may produce an ileus. Recovery from an ileus occurs gradually through definite stages which can be recognized clinically. If tone is also lost there is paralytic ileus, with abdominal distension and third-degree bowel sounds. Thus 5 different states of bowel activity are descriptionbed and the treatment for them is outlined. Various factors stimulate the bowel and should be avoided except with normal intestinal motility. The bowel sounds descriptionbed are recorded by means of a phonocardiogram placed on the abdomen.
1. Of 36,510 individuals X-rayed on 70 mm. minifilms, 35,306 (96.7%) were found to have normal chests. 2. Fourteen (0.13 %) Europeans were found to show evidence of active pulmonary tuberculosis. 3. Two hundred and thirty-one (0.9 %) non-Europeans showed evidence of active pulmonary tuberculosis. 4. The difference between the incidence of pulmonary tuberculosis in the different categories of workers is not considered significant, but the incidence in the different racial groups is believed to be statistically important.
