Priapism is a rare condition in childhood; the majority of reported cases are in boys with sickle cell disease, where conservative management is often appropriate. Our experience with 4 cases, with differing aetiologies, and a review of the literature highlight the need for aggressive therapy when conservative measures fail.

Two children with cholelithiasis several years after relief of a duodenal atresia are reported. A survey of the literature on duodenal atresia suggests that there may be associated abnormalities in the biliary tract in this condition, and raises the possibility of cholelithiasis developing in these patients many years after successful relief of the duodenal obstruction by some form of by-pass procedure.
Routine circumcision is gaining popularity in our community, as it is said to be a safe and painless operation in the neonate, and offers improved hygiene. That the circumcised foreskin is cleaner is undisputed, but whether the operation is safe is questioned. This article reviews the common problems encountered, and also reviews the physiology of the foreskin. The pros and cons of circumcision is discussed together with some complications of circumcision. The view is expressed that routine circumcision should not be encouraged.
Appendicitis remains one of the commonest paediatric surgical emergencies in a busy paediatric surgical practice. In spite of improved diagnostic skills and surgical care, the incidence of severe appendicitis has remained unaltered in children over the past few decades and therefore remains a therapeutic challenge. A protocol for the treatment of severe appendicitis was instituted in the Division of Paediatric Surgery at the Royal Canberra Hospital by the author from 1981 to 1984 inclusive, and the results of treatment according to the protocol are presented. The results suggest that an aggressive approach to gangrenous and perforated appendicitis can result in very low morbidity from sepsis. The protocol is discussed.
