Prostaglandin E2 (PGE2) is known to induce structural changes in the uterine cervix that produce thinning, softening, and eventually dilatation. In this paper, three certified nurse-midwives share their clinical experiences in using prostaglandin gel as a stimulus for labor.

Clinical staging is often inaccurate in the evaluation of local extension of cervical carcinoma. In the present study the sensivity of MR imaging in predicting extracervical tumor invasion on the basis of the detection of a thinning of the univolved cervical stromal ring (3 mm or less) was compared to the sensivity achieved by direct visualization of a complete stomal interruption. Fifteen consecutive patients with adenocarcinoma of the uterine cervix (FIGO stage Ib-IIa), were examined with axial and sagittal weighed MR sequences. Pathologic proof after hysterectomy was obtained in all subjects. The sensitivity in predicting extracervical involvement on the basis of the MR Imaging visualization of a thinned stroma was 83%, whereas the sensitivity obtained by detection of a complete stromal interruption was 50%. Among women with a spared cervical stroma of more than 3 mm at MR Imaging, only one had at pathologic examination microscopic metastasis in a parametrial lymphnode, accounting for a negative predictivity value of 87%. The results of our study points out a high concordance between MR Imaging findings and pathologic results, and indicate that the detection of a intact cervical stromal ring exceeding 3 mm at MR imaging is related to a very low risk of extracervical seeding of tumor. On the other side, the detection of a thinned stromal ring is related to a high incidence of parametrial invasion. The information obtained by this imaging technique may therefore be extremely useful in the accurate tailoring of treatment for these patients.

Pyometra is the accumulation of pus in the uterine cavity, thus stretching its walls and thinning and enlarging the uterus. This change is characteristic of the senium period of life, when the uterus is atrophic with a stenotic cervical canal. It most frequently occurs as a result of secondary infection of the cancerogenic tissue of the uterus and additional stenosation and clogging up of cervical canal by a malignant process. Apart from carcinomas of the body and uterus cervix, pyometra less often can occur in other illnesses such as senile endometritis and senile colpitis. As pyometra most frequently occurs in uterine carcinomas, in detection of this state, we must think of malignancy and direct our examination to this direction. In this paper we present a patient in whom pyometra developed because she carried an intrauterine device for forty years that resulted in chronic endometritis. The main symptoms for which the patient was admitted to hospital were abdominal pain and intensive suppurative vaginal excretion a month after removal of intrauterine device. The diagnosis of pyometra was made by gynaecological and ultrasound examinations, and also on the basis of gynaecological and ultrasound examinations one month after chronic endometritis was confirmed. On the basis of this finding we suspected that chronic endometritis was caused by this state. By cytological, PAP and histopathological examinations of samples obtained by explorative curettage and biopsy of the uterine cervix, malignant changes were eliminated a possible cause. By laboratory analysis and bacteriological examination of the uterine cavity and vaginal excretion, inflammatory changes of the uterine mocous membrane were confirmed as a cause of the pyometra. This conditions was due to carrying the intrauterine device for more decades. The therapy consisted of dilatation of the cervical canal and evacuation of accumulated suppurative contents and irrigation of uterine cavity with 3% solution of hydrogen peroxide and Povidon. Also wide spectrum antibiotics and uterotonics were given. Such treatment contributed to a fast and effectious recovery.

Intracervix injection of hyaluronidase during pregnancy has been proposed to accelerate cervix ripening. We evaluated the morphological and morphometric changes of the uterine cervix of pregnant rats, caused by the action of this enzyme. Ten female rats were equally divided between an experimental group (G II) and a control group (G I). On the 20th day of pregnancy, under light microscopy, a greater thinning of the superficial muciferous epithelium, with lamina propria rich in blood vessels and in eosinophils was found in G II. The histometric count of G II showed a smaller number of collagen fibers (average 248 vs 552 in the control group) and a greater concentration of eosinophils (average 18.20 vs 9.20 in the control group). The Student's t-test showed a significant difference in collagen fibers (p < 0.0001) and in eosinophils (p < 0.0007). The action of this enzyme caused a predominance of flaccid connective tissue, a lower concentration of collagen fibers and an increased concentration of eosinophils, confirming its utilization in cervix ripening.
