Study objectiveTo evaluate the long-term effectiveness of laparoscopic cryomyolysis as a minimally invasive technique for the treatment of symptomatic uterine myomas in menstruating women.DesignOpen, one-arm pilot study (Canadian Task Force classification II).SettingUniversity-affiliated public hospital.PatientsTwenty patients with symptomatic uterine myomas were treated with directed cryomyolysis. All had reported abnormal bleeding and/or pelvic pain/pressure and/or urinary frequency. Myoma diameters varied from 4 to 10 cm.InterventionOne-year follow-up after laparoscopic-directed cryomyolysis.Measurements and main resultsLaparoscopic cryomyolysis was performed using the Her Option Cryoablation Unit (American Medical Systems, Minneapolis, MN). Patients were evaluated 1, 3, 6, 9, and 12 months after surgery. Power color Doppler ultrasound was performed preoperatively and postoperatively to demonstrate the effectiveness of the technique in reducing or eliminating the primary blood supply to the myomas, as well documenting regression of the myomas.All patients reported a high rate of satisfaction with the treatment including absence of symptoms 12 months after surgery, with no bleeding and no myoma-related symptoms, comparable with patients who underwent hysterectomy. Mean shrinkage of myoma volume increased until 9 months after surgery (59.5% ± 13.2%), reaching a steady mean-volume reduction of approximately 60% (61.9% ± 11.9%) 12 months after surgery.ConclusionsDirected laparoscopic cryomyolysis appears to be an effective and safe technique for providing rapid symptom relief and at least 12 months’ effectiveness in the treatment of symptomatic uterine leiomyomas.

In a regional cohort of very preterm infants, repeated antenatal corticosteroids were associated with lower risk of cerebral palsy, but higher risk of hyperactive behaviors.

OBJECTIVE:The purpose of this study was to develop a minimally invasive, safe, and effective technique for managing symptomatic uterine myomas.STUDY DESIGN:Twenty patients with symptomatic uterine fibroids were treated. All had complaints of abnormal bleeding and/or pelvic pain/pressure and/or urinary frequency. Myoma diameters were 4 to 8 cm. Power color Doppler imaging was performed preoperatively and postoperatively to determine the effectiveness of cryomyolysis in reducing or eliminating the primary blood supply, as well as regression of the myomas. Laparoscopic cryomyolysis was performed with use of the Her Option Cryoablation System (American Medical Systems Gynecology, San Diego, Calif). Patients were evaluated at 1, 3, and 6 months postoperatively.RESULTS:All patients were discharged within 24 hours of treatment. No intraoperative or postoperative complications occurred. Of the 20 patients treated, 19 had complete resolution of their complaints. Myomas regressed up to 80%, and major blood supply to the myomas was eliminated.CONCLUSION:Directed laparoscopic cryomyolysis is an effective and safe technique for symptom relief from leiomyomas.

The purpose of this article is to report the incident cases of intraepithelial neoplasia of the cervix and vagina among patients in the National Collaborative Diethylstilbestrol Ad-enosis Project. Incidence rates for dysplasia/carcinoma in situ have been calculated and analyses have been performed i

An analysis of 6055 colposcopically directed biopsy specimens from 2635 diethylstilbestrol (DES)-exposed women and 445 biopsy specimens from 277 nonexposed women was undertaken to correlate microscopic findings with colposcopic patterns. All examinations were performed using a standardized protocol which required that each participant have colposcopy, cytologic smears, and biopsy of abnormal colposcopic lesions. The findings of colposcopic "columnar epithelium, gland openings, and Nabothian cysts" correlated most often with glandular epithelium in the biopsy specimen. "White epithelium," which includes three related colposcopic patterns, mosaicism, punctation, and white epithelium, was associated most frequently (82-93% of cases) with squamous metaplasia, but occasionally with dysplasia and carcinoma in situ (CIS)(0-6%). The presence of dysplasia or CIS in any individual biopsy specimen occurred most frequently with the observation of higher graded lesions by colposcopy or a prior diagnosis of dysplasia.

The incidence rates of dysplasia and carcinoma in situ (CIS) of the cervix and vagina were determined in 3,980 young women exposed prenatally to diethylstilbestrol. Strict criteria were developed to minimize selection bias among the subset of 744 pairs of matched exposed and unexposed (control) cohort participants, all of whom were identified through review of prenatal obstetrical records. A high degree of compliance was achieved throughout the seven-year study period since in each group about 90% of the women remained as active participants, kept 77% of the annual anniversary examinations, and had separate Papanicolaou smears of the cervix and vagina performed in 99% of the anniversary examinations. The incidence rate for dysplasia and CIS was significantly higher in the women exposed to diethylstilbestrol than in those not exposed in the matched cohort (15.7 v 7.9 cases per 1,000 person-years of follow-up). The rates were higher in the exposed women if squamous metaplasia extended to the outer half of the cervix or onto the vagina. In other respects, the matched cohorts were strikingly similar.

Immunoperoxidase localization of a human papilloma virus structural antigen (HPV) was attempted in 68 intraepithelial lesions of the vulva, 39 of which were analyzed for nuclear DNA content by microspectrophotometry. Overall, 5.9% (4/68) stained positive for HPV. Ninety percent (35/39) of the cases tested were aneuploid, and, of these, 2.8% (1/35) stained positive for HPV. In contrast, 50% (2/4) of the polyploid lesions were positive. Hence DNA microspectrophotometry and immunoperoxidase localization of HPV are useful coparameters for distinguishing wart virus infection (condylomata) from vulvar intraepithelial neoplasia. HPV is detected infrequently within aneuploid lesions, in keeping with the concept that epithelial maturation is required for virion assembly. Whether the HPV genome exists in a nonreplicative state within the aneuploid cell population is unknown.

This report presents the cytologic findings and the rates of dysplasia for 4,589 young women enrolled in the National Cooperative Diethylstilbestrol-Adenosis (DESAD) Project. Mucinous columnar cells and/or metaplastic squamous cells with or without mucinous droplets were encountered in 22% of vaginal scrape smears from all diethylstilbestrol (DES)-exposed participants identified by review of prenatal records and in 43% of women in whom vaginal epithelial changes (VEC) were observed by colposcopy or by iodine staining. The frequency of cellular findings in the vaginal scrape smears was closely related to the timing of the administration of the DES to the mother. With increasing age of the daughters, the overall frequencies of both the mucinous and metaplastic cells decreased; relative to each other, an increasing proportion was metaplastic squamous cells. These data suggest that, as the women grow older, vaginal adenosis regresses by the process of squamous metaplasia. Endometrial type cells were found in 2% of vaginal scrape smears. Their cyclical occurrence during the menstrual cycle and lack of correlation with the presence of VEC indicated an origin from the uterine corpus rather than the tuboendometrial type of adenosis. Squamous cell dysplasia of the vagina and cervix was detected by biopsy or scrape smear specimens in 1.8% of DES-exposed women in the record review group. The rate in unexposed women was twice as high. In general, the rates of dysplasia were higher in the cervix than vagina, and the more severe degrees of dysplasia were encountered only in those women who were referred to the DESAD Project or who themselves requested entry. Four patients who were referred or who themselves requested entry were found to have clear cell adenocarcinoma of the vagina. The vaginal smear provided the first clue to the presence of an abnormality in three of them.

A study was conducted of siblings and matched pairs with regard to DES and unfavorable outcomes of pregnancy. No substantial difference was found in relative risk. Numerically the estimated crude relative risk was higher in the sibling pairs. Because many sibling and matched pairs were discordant for pregnancy (since the young women were just beginning their reproductive careers) the numbers were small. Data from the National Cooperative Diethylistilbestrol Adenosis Project (DESAD) on outcome of pregnancy in daughters whose mothers reported a history of problems in pregnancy show no difference in reproduction performance in these daughters as compared with daughters whose mothers had not had problems in prengancy. This was true for both the DES-exposed group and the control group. Infertility another indication for the use of DES may be partly explained by paternal factors. It seems unlikely that DES-exposed women are on the whole genetically at risk for failures in pregnancy. Neither Ferguson nor Dieckmann et al. found evidence that DES had an effect on outcome of pregnancy and this lack of evidence makes it seem unlikely that daughters exposed to DES would not otherwise have been born.

The National Cooperative Diethylstilbestrol Adenosis (DESAD) Project has completed the major portion of its enrollment phase with the examination of more than 3000 daughters of women taking synthetic nonsteroidal estrogens (denoted DES) during pregnancies occurring from the early 1940s to the mid-1960s. The aims of the Project are to fill urgent needs for information on the prevalence and incidence of structural and epithelial abnormalities or neoplastic changes and their complications in these young women. Participants are grouped by mode of entry as identified by prenatal record review (40.1%), documented as DES-exposed but walking in (25.1%), or referred (22.8%) to the DESAD Project for examination, and not documented as exposed but having gynecologic abnormalities typical of those associated with DES exposure (12.0%). This study cohort, in part having paired controls, will be examined annually for at least 5 years. Details of the design and selected preliminary findings are reported.

Colposcopy, including colposcopically directed biopsies in selected cases, was employed to evaluate over 300 pregnant patients with abnormal Papanicolaou tests suggestive of mild dysplasia or worse (Class III to V). Over half of the patients had benign disorders determined by colposcopic examination. All cases of invasive disease were diagnosed by colposcopy and biopsy, and the patients were treated accordingly. Only 3 diagnostic conizations were necessary in the antepartum period. The majority of patients with cervical intraepithelial neoplasia were seen post partum, and appropriate therapy was instituted. In the pregnant patient with an abnormal Papanicolaou test, colposcopy has proved to be a reliable and safe method of evaluation and has virtually eliminated the need for conization.
