Autoerythrocyte sensitization syndrome (psychogenic purpura).

A case of autoerythrocyte sensitization syndrome is reported. This syndrome most often appears in young women who have an underlying emotional disorder; features include bizarre, tender ecchymotic lesions, which are most commonly located on the arms and legs. Systemic symptoms often accompany the onset of these lesions. A diagnosis of autoerythrocyte sensitization syndrome may be made in a patient who has the typical history and clinical picture of the syndrome and in whom a skin test with use of the patient's blood reveals a positive reaction.

Depression of lactose hydrolysis by yeasts.

To investigate the role that the known disaccharidase depression may play in the aetiology of infant gastroenteritis caused by Candida albicans, C. albicans and the rarely pathogenic, Saccharomyces cerevisiae were studied by three different methods. Both types of yeast significantly depressed the lactose-hydrolysis activity of beta-galactosidase, and both depressed lactose hydrolysis in the ligated small intestine of infant rabbits, either in intact animals allowed to survive for 10 h, or in a physiological bath for 20 h. The depression of lactose activity was not temperature dependent; living and inactivated yeast preparations produced comparable degrees of depression of enzyme activity. It is concluded that the depression of lactose hydrolysis is not a virulence factor of C. albicans, but contributes to the often observed disaccharide intolerance associated with candida gastroenteritis in infants.
