ABSTRACT
It was found that the build-up of simuliid numbers subsequent to the construction of dams in the Vaal and Orange Rivers could be successfully prevented by periodic, artificially controlled reductions in the water-levels in these rivers.

Patients with acute losses of large portions of the anterior abdominal wall are discussed. Management is divided into the acute or immediate phase in which initial wound control is paramount, and then a subacute period in which coverage with skin is accomplished. Many weeks later during the chronic phase, reconstructive procedures are done if needed. Methods of handling these defects are presented.

Sacrococcygeal teratomas are unusual tumors in children, and are extremely rare in adults. A review of the literature has revealed 69 reported cases of presacral teratomas in adults, and an additional two cases are presented, one in association with a meningocoele. Surgical excision is the treatment of choice. Malignant changes were noted in 11 per cent of cases.
