A patient receiving oral contraceptive hormone therapy developed a hepatic adenoma. Widespread haemorrhages, which were apparently unrelated to trauma, developed in the adenoma. Attention is drawn to the increasing incidence of Pill-associated hepatic tumours, and to the possibility of a fatal haemorrhage.
A case is reported of an 11-month-old baby suffering from gangrene of the distal portion of the small bowel due to infestation by larval worms belonging to the order Spirurida, family Physalopteridae and probably the genus Physaloptera. Microscopically, the resected bowel showed ischaemic necrosis, eosinophilic granulomata and larval worms in the lumen and wall of blood vessels. The inflammatory process extended into the mesentery, where the vessels showed focal necroses, thrombosis and endarteritis. Infection in this child in the Queensland countryside is considered to have resulted from ingestion of insects on grass eaten when at play, the grass having been contaminated by bandicoots.
A case is reported illustrating the typical features of Tay-Sachs disease, the light microscopy and ultrastructure of the stored material in the condition, and the feasibility of prenatal diagnosis of the disorder.
