1. A bilharziasis survey based on the examination of a single-urine specimen of school children was carried out in the northern environs of the Witwatersrand. 2. European and Bantu boys and girls between the ages of 10-16 years showed the highest incidence rate. 3. Considering only those schools which are situated near the Klein Jukskei River, European children in the 10-16 age group show an infection rate of 10% and Bantu children 20%. 4. Physopsis snails from the Klein Jukskei were found to be vectors of B. haematobium under experimental conditions. 5. The area is known to be heavily infected with B. bovis, yet only one human infection was revealed by the survey. It is concluded that human beings are not readily susceptible to bovis infections.
1. The procedure in the handling of supracondylar fractures of the humerus in children is discussed, and the technique in the reduction of these fractures is descriptionbed. 2. Emphasis is laid on the first manoeuvre of the reduction. It is more important to know where the proximal fragment is than to rely on the textbook emphasis on the distal fragment. 3. Criticisms are levelled at Watson-Jones' insistence on the correction of the lateral displacement after the correction of the posterior displacement, and at his recommendation of repeated manipulations
