Upper genital tract infection was investigated in 45 women admitted to hospital for suspected acute pelvic inflammatory disease (PID). Salpingitis was diagnosed by laparoscopy in 30 (67%) women. Histopathological evidence of endometritis was found significantly more often in the 30 women with salpingitis (87%) than in the other 15 women without salpingitis (33%). C. trachornatis or N . gonorrhoeae, or both, were isolated from the upper genital tract in 14 of the 31 women who had both salpingitis and endometritis or endometritis only but in none of the four women who had salpingitis alone and in none of the 10 women who had no evidence of PID. Bacterial vaginosis was associated with histopathological evidence of upper tract infection. Non-chlamydia1 nongonococcal organisms were frequently isolated from the upper genital tract. Noorganismswereisolatedfrom the uppergenitaltractfrom9of35 women with laparoscopic or histopathological evidence of PID compared with 7 of 10 women without evidence of PID. C. trachomatis or N . gonorvhaeae in the endometrium was associated with lymphoid follicles comprising transformed lymphocytes, and correlated with the density of plasma cells on biopsy. The microbiological results support the recommendations of broad spectrum antimicrobial therapy for PID.The concept of the pathogenesis of acute pelvic inflammatory disease (PID) has remained
The purpose of this study is to evaluate the risk factors of benign breast disease and to compare them with the known risk factors of breast cancer in order to make inferences on the relationship between benign breast disease and breast cancer. All benign breast lesions diagnosed from the population of the city of Tampere, Finland in 1974-1977 were reclassified by two pathologists into two groups of dysplasias and two groups of tumors. In the risk analysis of 422 age-matched pairs no group of benign lesions had risk factors consistently similar to those of breast cancer. It is therefore likely that either benign breast disease is not associate with breast cancer or it is an independent risk factor, not associated with the other high risk indicators of breast cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
