Extended carbon dioxide laser vaporization in the treatment of subclinical papillomavirus infection of the lower genital tract.

This study examined the use of extended carbon dioxide laser vaporization in 25 women with histologically confirmed, multicentric subclinical papillomavirus infection of the lower genital tract to determine whether carbon dioxide laser can eradicate subclinical papillomavirus infection. An extended carbon dioxide laser procedure involved vaporization of the epithelium of the entire lower genital tract. We performed the procedure under colposcopic guidance. Vaporization was carried out in continuity, to an appropriate tissue depth, while using recommended power densities for the respective target tissue. For sexually active study patients, male consorts were evaluated and treated concurrently to reduce the risk of recurrent infection. Postoperative morbidity was considerable, with moderate to severe vulvar pain and febrile reactions occurring in 100 and 76% of patients, respectively. Histologic persistence of subclinical papillomavirus infection was documented in 88% of study patients at follow-up examination. Neither treatment of the male consort nor sexual abstinence significantly improved treatment outcome. These data suggest that extended carbon dioxide laser procedures cause significant short-term morbidity without effectively eradicating subclinical papillomavirus infection of the female lower genital tract.

Endometrial effects of lower doses of conjugated equine estrogens and medroxyprogesterone acetate.

OBJECTIVE: To determine the endometrial safety of lower doses of continuous combined conjugated equine estrogens (CEE) and medroxyprogesterone acetate (MPA). DESIGN: Randomized, double-blind, placebo-controlled study (the Women's Health, Osteoporosis, Progestin, Estrogen study). SETTING: Study centers across the United States. PATIENT(S): Healthy, postmenopausal women (n = 2,673) with an intact uterus. INTERVENTION(S): Patients received CEE 0.625 mg/day, CEE 0.625/MPA 2.5 mg/day, CEE 0.45 mg/day, CEE 0.45/MPA 2.5 mg/day, CEE 0.45/MPA 1.5 mg/day, CEE 0.3 mg/day, CEE 0.3/MPA 1.5 mg/day, or placebo for 1 year. Endometrial biopsies were evaluated at baseline, cycle 6, and year 1 using a centralized protocol. MAIN OUTCOME MEASURE(S): Efficacy of lower doses of CEE/MPA in reducing the incidence of endometrial hyperplasia rates associated with unopposed CEE. RESULT(S): Endometrial hyperplasia rates ranged from 0 to 0.37% for all CEE/MPA doses. Twenty-nine of the 32 cases of endometrial hyperplasia developed in women who were administered CEE 0.625 mg or CEE 0.45 mg. The incidence of endometrial hyperplasia increased with age for patients administered CEE alone. As expected, there were some inconsistencies among pathologists' ratings in the numbers of hyperplasias and incidence rates for the CEE-alone regimens. There were too few cases of hyperplasia in the combination groups to evaluate consistency among pathologists. CONCLUSION(S): One year of treatment with lower doses of CEE/MPA provides endometrial protection comparable to commonly prescribed doses. These regimens may be used by clinicians to individualize hormone replacement therapy in postmenopausal women.

Leiomyoma uteri in a rudimentary uterine horn in a woman with the Rokitansky-Kuster-Hauser syndrome. A case report.

A 4-cm leiomyoma was found in a woman with the Rokitansky-Kuster-Hauser syndrome. It was discovered six years after she presented to a gynecologist. In the ensuing years she successfully developed vaginal dilation. This is the fourth reported case of leiomyoma associated with the Rokitansky-Kuster-Hauser syndrome.

Vaginal and vulvar adenosis. An unsuspected side effect of CO2 laser vaporization.

During a 15-month period, September 1984 through January 1986, 10 women who were treated in the Section of Gynecologic Oncology, Department of Obstetrics and Gynecology, Pennsylvania Hospital, Philadelphia, Pennsylvania, developed vaginal or vulvar adenosis after CO2 laser vaporization. The indications for therapy were condylomata of the cervix, vagina and vulva refractory to conservative management in 3 patients, vulvar intraepithelial neoplasia in 3, lichen sclerosus in 1 and cervical intraepithelial neoplasia with condylomata on the cervix and vagina in 3. All the patients underwent treatment of the vagina. Most underwent treatment of the cervix, and some underwent treatment of the vulva at various degrees of intensity and depth. During the posttreatment colposcopic follow-up examination, all the patients demonstrated lesions colposcopically consistent with adenosis of the vagina or vulva within the area treated with the CO2 laser. Biopsies of the lesions were performed, adenosis was confirmed histologically, and endometriosis was ruled out histologically. This entity has not been previously associated with CO2 laser vaporization, and its clinical significance is undetermined. Further follow-up is indicated.
