Diagnostic dilemmas of Wilson's disease: diagnosis and treatment.

Wilson's disease, an autosomal recessive disorder of copper metabolism, may defy diagnosis in children. The classical triad of Kayser-Fleischer rings, neurologic dysfunction, and hypoceruloplasminemia may be absent. Patients may be seen initially with acute or chronic hepatitis, hemolytic anemia, or neurologic dysfunction. Guidelines are presented for diagnosis of Wilson's disease based on a review of 25 pediatric and adolescent patients. A high index of suspicion in necessary so that therapy with penicillamine may be begun before irreversible liver or neurologic damage occurs. The prognosis is excellent when diagnosis and treatment are established early.

Persistent high intestinal lactase activity in Papua New Guinea. The breath hydrogen test in a Sepik population.

A sample of volunteers from the north-west of Papua New Guinea has been tested for persistent high intestinal lactase activity by measuring the breath hydrogen content before and after the administration of a preparation containing 50 g lactose. Eight of 35 persons were found to be absorbers of lactose. In common with other recent studies, this proportion establishes that the polymorphism occurs on the island, though the frequency of absorbers is nowhere high. The breath hydrogen method of estimating status has been shown to be capable of providing unequivocal, convincing results in the field.
