Patients who received LVADs were less severely ill before the operation and consequently were more likely to survive after the operation. As the severity of illness increases, patients are more likely to require biventricular support.

The initial clinical experience suggests that the AbioCor might be effective therapy in patients with advanced biventricular failure. There have been no significant device malfunctions. Two of these patients have been discharged from the hospital.

It is postulated that squamous cell carcinoma, adenocarcinoma, and mixed adenosquamous cell carcinoma of the uterine cervix all have a common cell or origin, the subcolumnar reserve cell. The relative frequency with which the various types of carcinoma in situ are seen is in part explained by the ubiquitous nature of squamous metaplasia in the region of the transformation zone in women of reproductive age. It is suggested that squamous metaplasia is the soil on which most squamous carcinomas of the cervix evolve. The relatively low frequency with which adenocarcinoma and adenosquamous carcinoma in situ are encountered may also be dependent on their less accessible location in the endocervix.
