Malignant melanoma: a review.

The incidence of malignant melanoma the most malignant of all skin neoplasms, has doubled within the last 10 years. Exposure to high intensity sunlight, racial susceptibility, hormonal status, age, environmental factors as well as injury have all been shown to play a role individually or synergistically in the activation of the melanocytic oncogen. Controversies still exist in which factors actually determine prognosis, in patients with advanced malignant melanoma. Management has remained even more controversial, with surgical excision, with or without lymphadenectomy, radiotherapy, chemotherapy, laser therapy and more recently immunotherapy and intra-arterial neutron thermal capture therapy, having their proponents and opponents.

Fournier's gangrene in neonates and infants.

BACKGROUND: Fournier's gangrene is uncommon in childhood and little is known about the disease in this age group. METHOD: A retrospective review was carried out of neonates and infants treated for Fournier's gangrene over a period of 16 years. RESULTS: Twelve neonates and infants aged 5 days-3 months (median 3 weeks) were treated in our hospital. The precipitating cause was omphalitis in 7 babies, strangulated inguinal hernia in 2 and in 3 babies there was no identifiable cause. Gram-negative bacteria were cultured in 3 patients, but in most the culture was sterile. Treatment consisted of debridement of devitalised tissue and administration of broad-spectrum antibiotics. Primary closure was achieved in 1 baby and secondary closure in 2 others. In 7 babies the wound contracted rapidly and healed. There was no mortality. CONCLUSION: Fournier's gangrene in neonates and infants in our environment is largely preventable. Early debridement and appropriate antibiotics give good results.
