A case in which a pedunculated neoplasm of the right main bronchus acted as an inspiratory ball valve obstruction is descriptionbed. This action is the reverse of the classical expiratory ball valve obstruction and is extremely rare. The radiological and surgical findings are discussed.
The orthodox radiological methods may give considerable assistance in the diagnosis of myocardial infarction and cardiac aneurism while the newer methods of radiological investigation such as electrokymography may give us more information heretofore not obtainable by any other known means.
Thirty consecutive autopsies were done on African adult females found to be suffering from schistosomiasis. All had a S. haematobium infestation but, in addition, 12 showed infection by S. mansoni. In each case the vagina, cervix. uterus, Fallopian tubes and ovaries were examined separately for ova by the digestion method. The vagina had ova in 97% of the cases. the cervix in 93%, the uterus in 83%. the ovaries in 80% and the Fallopian tubes in 53%. In almost every instance the ova were those of S. haematobium. S. mansoni, however, rarely infected the female genitalia. The significance of these findings is discussed.
