Epidemiological data, cytology and colposcopy in IUD (intrauterine device), E-P (estro-progestogens) and diaphragm users. Study of cytological changes of endometrium IUD related.

: The author compares the epidemiological, cytological and colposcopical data found in IUD users, with a control population of estro-progestogens and condom users. The age, parity and clinical symptomatology, mainly leukorrhea, was higher in IUD users. At the colposcopic examination a normal pattern was found in condom users more frequently, but the suspect colposcopic signs were frequently associated with the use of the IUD. The oncologic evaluation of smears showed a slight dysplasia in 17.65% and 10.53% in IUD users and estro-progestogen users respectively. The only case of carcinoma in situ was found in the IUD users group. The bacteriological diagnosis on the smears did not reveal a quantitative difference in the three groups, while a qualitative difference was found, particularly with a high frequency of Trichomonas vaginalis and Corynebacterium vaginalis, and one case of Actinomyces in IUD users. The cytological study of the endometrium obtained by mono-use devices, revealed an aspect of aspecific non plasmacellular endometritis in 75% of the cases; a dysfunctional hormonal cytological aspect in 32.50%, and the oncological evaluation in 60% of the cases revealed atypical endometrial cells IUD related. No neoplastic lesion was found. The author concludes that the use of IUD must be prudent and accurate follow up must be carried out.
