Ultrasound estimation of myometrial invasion of endometrial cancer by intrauterine radial scanning.

The myometrial invasion of endometrial cancer was estimated by using intrauterine radial-scan ultrasonography and classified into the following four groups: no myometrial invasion, superficial invasion (below one-third), moderate invasion (above one-third but below two-thirds), and deep invasion (above two-thirds). The myometrial invasions were further examined histologically on the removed uterus. In 26 of 32 cases (81.3%), estimations by intrauterine radial scans agreed with the histologic assessment. In each of the remaining six cases, estimations by radial scans were lower than those by histologic examination.

Season of birth of chronic alcoholics.

Season of birth has been well studied in mental illnesses, such as schizophrenia and affective disorders; however, only a few studies have been done for alcoholism. Recently Modestin et al. (1995) found, in a sample from Switzerland, excess birth of male alcoholics in March to July, compared to the general population. The present study attempted to replicate their finding in two independent Japanese samples which comprised a total of 1,947 men with chronic alcoholism. In our study, no birth rate excess in March to July was observed in either sample, while a non-significant birth rate excess (12%) in August to October was noted. It is concluded that there is no consistent trend in season of birth of alcoholics across countries.

Development of a three-dimensional color Doppler system.

An unprecedented assembly of a three-dimensional (3D) color Doppler system was arranged for the purpose of producing and displaying precisely calculated and recorded 3D color flow mapping images of fetal and umbilical vessels. Data accuracy and quality were enhanced by a computer controlled probe positioner. Scanning was across any of three perpendicular planes to collect serial slice images in any position and interval width. The series of parallel images was digitized in a color imaging processor by a 3D reconstruction program. Analyzed data were transferred to work stations for immediate processing into 3D form and display. The resulting 3D display was a solid model image of umbilical vessels which could be rotated in real time. In addition to the clear information about the vessel's structure, hemodynamics were apparent.

Appraisal of self-collected cervical specimens in cytologic screening of uterine cancer.

Cytologic specimens were collected simultaneously by three methods on 122 patients with cervical neoplastic lesions: self-irrigated collection, self-scraped collection and physician-scraped collection. In invasive epidermoid carcinoma, the accuracy with the self-collected specimens approached the physician-scraped specimens. There was a serious defect in the detection of cervical intraepithelial neoplasia by the self-irrigation method. In carcinoma in situ and dysplasia, the self-scraping method was considerably better than the self-irrigation method. In mass screening of 89,206 females, the self-scraping positive detection rates were closer to the physican-scraping results than the self-irrigation method.
