Changes and challenges for women in academic obstetrics and gynecology.

In obstetrics and gynecology, more than 60% of current residents and 36% of medical school faculty are women. However, fewer than 10% of professors and only a small number of department chairs and organizational leaders are women. This paper reviews the data on the growing number of women in obstetrics and gynecology, and in medicine in general, during the past 25 years. It reviews some of the challenges that women have faced and some strategies to enhance equitable opportunities.

Obstetrics and gynecology residencies: education in preventive and primary health care for women.

OBJECTIVE: To test the hypothesis that the Residency Review Committee program requirements for obstetrics and gynecology residencies, when properly followed, will result in residents being educated in preventive and primary ambulatory health care for women during their residency training program as specialists in obstetrics and gynecology. METHODS: The 60 requisite residency training competencies identified as essential to educate generalist physicians, and viewed by some educators as a benchmarking standard, each were evaluated to determine whether residents in obstetrics and gynecology are now being educated in each of these areas. The answer was considered affirmative if any of the following pertained: 1) the Residency Review Committee program requirements indicate that the competency "must" or "should" be taught, 2) the Residency Review Committee requests numerical verification related to the competency on the accreditation review application, or 3) by virtue of a specific rotation required by the Residency Review Committee it can be assumed that the resident will be educated in the competency. To make our assessment, we identified and listed the section of the Residency Review Committee for Obstetrics-Gynecology program requirements, which, when properly followed, would result in education in the particular competency. RESULTS: Fifty-seven of the 60 competencies were considered applicable to obstetrician-gynecologists (care of infants, care of children, and infant/child preventive care were not), and residents in obstetrics and gynecology were found to be educated in 54 (95%). CONCLUSION: During their residency training programs as specialists in obstetrics and gynecology, residents are being educated to be able to be providers of preventive and ambulatory primary health care for women.

Hormone production by the postmenopausal ovary in cases of benign ovarian neoplasia.

OBJECTIVE: The objective of this study was to determine whether hormone production by postmenopausal ovaries containing benign ovarian tumors differed from that of normal postmenopausal ovaries. STUDY DESIGN: The sera of 32 postmenopausal patients were assayed before and after bilateral oophorectomy for estrone, 17 beta-estradiol, androstenedione, testosterone, and dehydroepiandrosterone sulfate. The data from all patients as a group were analyzed, followed by analysis of the data from 15 patients with normal ovaries separately from the remaining 17 patients who had nonfunctioning, benign ovarian tumors. RESULTS: For patients with benign ovarian tumors there was a statistically significant drop in estrone (from a presurgical level of 55.8 +/- 46.3 pg/ml to a postoperative level of 29.9 +/- 10.2 pg/ml, p < 0.03) and 17 beta-estradiol (from 18.6 +/- 14.1 pg/ml preoperatively to 9.8 +/- 3.8 pg/ml postoperatively, p < 0.02). For postmenopausal woman with normal ovaries there was no significant drop in estrone or 17 beta-estradiol after bilateral oophorectomy. There was a statistically significant drop in testosterone and androstenedione after bilateral oophorectomy both for women with normal ovaries and for those with benign tumors. No significant differences in dehydroepiandrosterone sulfate were noted in either group. CONCLUSIONS: These data suggest that, although normal postmenopausal ovaries have not been demonstrated to secrete clinically significant amounts of estrogen, those that contain benign ovarian tumors do secrete small but significant amounts of estrone and 17 beta-estradiol. Both tumor-containing and normal ovaries secrete the androgens androstenedione and testosterone, this secretion not being significantly influenced by the presence of a tumor.

Excessive estradiol secretion in polycystic ovarian disease.

Polycystic ovarian disease is both a hyperestrogenic and a hyperandrogenic syndrome, and all studies have shown that hyperestrogenemia is the result of an elevation of estrone with plasma estradiol levels in the normal follicular range. Because a literature search failed to reveal any report of polycystic ovarian disease with significantly elevated estradiol levels, we report a case in which the plasma estradiol was so massively elevated as to mimic an estrogen-producing neoplasm. This case also suggests that although polycystic ovarian disease is a very rare cause of such excessive estradiol production, it should be included in the differential diagnosis of estrogen-producing neoplasms.

The use of large-loop excision of the transformation zone in an inner-city population.

OBJECTIVE: To determine whether large-loop excision of the transformation zone (LLETZ) can be used in our population to treat patients in a routine colposcopy clinic without diminishing the capability to see the large number of patients who require care, and to compare these results to our previous experience with laser surgery. METHODS: Patients found to have squamous intraepithelial lesions on colposcopically directed biopsies were offered treatment with LLETZ during counseling regarding their biopsy findings. Procedures included "ablation equivalents" and "cone biopsy equivalents" using local anesthesia. Follow-up examinations were used to determine cure and included cytology, colposcopy, and directed biopsies when indicated. The cure rate was compared to our previous experience with laser surgery. RESULTS: Two hundred thirty-six patients were treated in the colposcopy clinic without diminishing the capability to see all patients requiring care. Complications were few. The mean (+/- standard deviation) follow-up period was 50.7 +/- 25.3 weeks. The overall cure rate of 91.3% (95% confidence interval [CI] 87.1-95.5) was not influenced by the severity of the disease, but positive endocervical margins significantly lowered the cure rate to 69.2% compared with those who had negative margins. Before this series, only 73.1% of our patients scheduled for laser surgery returned for treatment. Assuming a 90% cure rate among those who returned, this means that the actual cure rate was only 65.8%. The likelihood of cure was 1.37 times greater (95% CI 1.27-1.52; P < .0001) using LLETZ in the clinic at the time the patient was counseled regarding her biopsy findings than using laser at a later date. In 33 patients, the LLETZ specimen showed no evidence of disease. The relative risk of negative histology was 3.31 (95% CI 1.78-6.13; P < .001) when LLETZ was done for a discrepancy between cytology and histology as opposed to any other indication. Cancer was found on the LLETZ specimen in four patients (two microinvasive, two frankly invasive), but was not suspected preoperatively in any of the patients. CONCLUSION: In our inner-city clinic, treatment with LLETZ at the time the patient was counseled regarding her biopsy findings improved the actual cure rate. The LLETZ procedure can be done safely in a clinic setting without diminishing the capability to care for a large number of patients.

The fourth-year medical school curriculum: recommendations of the Association of Professors of Gynecology and Obstetrics and the Council on Resident Education in Obstetrics and Gynecology.

OBJECTIVES: The Association of Professors of Gynecology and Obstetrics and the Council on Resident Education in Obstetrics and Gynecology have proposed a fourth-year medical school curriculum for a student interested in pursuing a residency in obstetrics and gynecology. STUDY DESIGN: Faculty members and residents in North Carolina, Illinois, and Michigan were surveyed as to the ideal curriculum that they would recommend for fourth-year students. The committee members representing the Council on Resident Education in Obstetrics and Gynecology and the Association of Professors of Gynecology and Obstetrics then reviewed these surveys and proposed a final curriculum. RESULTS: A core curriculum of general medicine as an acting internship, an intensive care unit rotation, neonatology, and emergency medicine was recommended. Additional courses strongly considered were ambulatory obstetrics-gynecology, acting internship in obstetrics-gynecology, endocrinology, and general surgery. CONCLUSION: The committee recommends a curriculum that is broad and balanced in general medical education.

Is human papillomavirus-related disease an independent risk factor for human immunodeficiency virus infection?

We sought to determine the prevalence of human immunodeficiency virus (HIV) infection in a population of women with human papillomavirus (HPV)-related diseases attending a colposcopy clinic who had no other CDC-defined risk factors for HIV. Study patients included all new patients attending our colposcopy clinic who were found to have histologic evidence of condyloma or cervical intraepithelial neoplasia. Those patients not already known to be HIV-positive were offered testing for HIV. Demographic information was obtained on all patients. Results were compared to data from anonymous testing of our own obstetrical population. One hundred forty of 208 women (67.3%) were either previously known to be HIV-positive or agreed to be tested. Sixteen (11.4%) were HIV-positive. Eight of the HIV-positive women were not previously known to be HIV-positive and 6 of the 8 had no definable risk factors for HIV infection. This is 4.6% of the women not already known to have a CDC-defined risk factor for HIV. The rate of HIV infection in our obstetrical population is 1.6%. In women without other definable risks for HIV infection and who had HPV-related disease the relative risk of HIV infection in our population was 2.94 (95% confidence interval 1.21-6.94; P < 0.031). In areas where HIV is endemic there is a high prevalence of HIV infection in women with HPV-related disease. Even in women without another definable risk factor for HIV, HPV-related disease may serve as a marker for an increased risk of HIV infection in this population.

Resident attrition in obstetrics and gynecology.

OBJECTIVE: Our goal was to determine the rate of attrition from obstetrics and gynecology residency programs. STUDY DESIGN: The Council on Resident Education in Obstetrics and Gynecology sent questionnaires to all 295 obstetrics and gynecology residency program directors in the United States and Canada. These programs represent 4306 postgraduate-year 1 through 4 (or 5) resident positions each year. The program directors were asked the number of residents who left voluntarily or were dismissed in a 2-year period and the reasons they left. RESULTS: In a 2-year period 299 residents left or were dismissed (6.94% over 2 years, or 3.47% per year). Only 88 (1% per year) left specifically because they decided they preferred a different discipline. CONCLUSION: The rate of attrition from obstetrics and gynecology residency programs is not excessively high.

Comparison of the adrenocorticotropic hormone stimulation test in the follicular and luteal phases of the menstrual cycle.

A comparison was made of the ACTH stimulation test in the proliferative and luteal phases of the menstrual cycle in 13 subjects, each of whom served as her own control. The test yielded a 53.9% false-positive rate in the luteal phase. The study, therefore, clearly shows that from a practical, clinical point of view, the test is completely unreliable in the luteal phase, and is only valid when carried out in the follicular phase of the cycle.

Patient-controlled analgesia for cancer pain: a long-term study of inpatient and outpatient use.

The safety and efficacy of patient-controlled analgesia for the long-term control of cancer pain was tested prospectively. Respiratory rates, mental status, and pain relief were recorded at baseline and compared with those during the study period. Patients had a lower analgesic demand (i.e., self-administered less morphine during the nighttime); specifically, dosing declined 48% from the daytime level. Respiratory rates did not change appreciably during the study and no cases of significant respiratory depression were encountered. Patients self-administered sufficient morphine to produce adequate but not complete pain relief in almost all trials. Pain relief was safely achieved by both intravenous and subcutaneous routes of administration in both the inpatient and outpatient settings. Mean 24-h morphine use stayed relatively constant even for patients receiving more than 2 weeks of treatment. In conclusion, patient-controlled analgesia is effective and safe therapy for the long-term control of severe cancer pain.

Accommodating to restrictions on residents' working hours.

In 1988, New York became the first state to implement regulatory measures limiting housestaff work hours. Because restrictions on residents' work hours will have such profound and far-reaching implications for how obstetrics and gynecology residencies are conducted, the Council on Resident Education in Obstetrics and Gynecology (CREOG) requested that a survey be conducted to solicit information from program directors of U.S. obstetrics and gynecology residencies who had already begun to alter their call schedules. Two hundred and ninety-six programs were contacted, and representatives of those that had implemented changes were requested to respond. Eighty-two responses were received; 26 of these contained information that could be collated. From these 26 responses the authors have structured a prototypic call schedule and presented its application. A key feature necessary to implement the new type of schedule is the use of a night float system. It is concluded that changes can and will be made by obstetrics and gynecology residencies. Creative scheduling, as described in this article, is essential and will facilitate the task; however, the current standards of education and patient care will be difficult to maintain without additional economic and human resources.

Serum estradiol as an aid in the diagnosis of ectopic pregnancy.

The value of serum beta-hCG measurement in the diagnosis of ectopic pregnancy is well established, and there have been recent studies on the use of serum progesterone levels. However, we have been unable to find any reports on the potential application of serum estradiol (E2) assays in the diagnosis of ectopic pregnancy. We therefore concurrently measured serum E2, progesterone, and beta-hCG in 100 women with ectopic pregnancies, as well as in 69 controls with normal intrauterine pregnancies and 36 women with threatened abortion. The mean (+/- standard deviation) E2 levels for ectopic-pregnancy patients, the normal controls, and the women with threatened abortion were 281.1 +/- 115.6, 788.2 +/- 45.5, and 788.8 +/- 40.6 pg/mL, respectively; the mean levels in the ectopic group were significantly different (P less than .0001) from those of the other two groups. All but one of the ectopic pregnancies had values below 650 pg/mL for E2 and 23 ng/mL for progesterone, and all but one of the normal intrauterine pregnancies had values above these levels. Our data suggest that the addition of the estradiol assay, with or without progesterone, to the early evaluation of patients suspected of having an ectopic pregnancy may be helpful in diagnosis.

Treatment of pulmonary endometriosis with a long-acting GnRH agonist.

We report the case of a patient who was successfully treated with a long-acting GnRH agonist for pulmonary endometriosis. This 28-year-old woman had symptomatic pleural endometriosis, documented by biopsies, as well as symptomatic pelvic endometriosis. Two surgical procedures, consisting of excision of pleural endometriotic tissue and partial pleurectomies, failed to relieve her chest symptoms. Little relief was achieved with pseudopregnancy treatment. Satisfactory symptomatic improvement was obtained with danazol, but this medication had to be discontinued because of severe side effects. Trial of a GnRH agonist, leuprolide acetate, achieved complete remission of her chest symptoms; in addition, the patient became pregnant immediately after cessation of therapy. Gonadotropin-releasing hormone agonist therapy may be an important therapeutic alternative for women with pulmonary endometriosis who cannot tolerate danazol treatment and in whom surgical therapy fails to relieve the chest symptoms.

Cervical os obliteration after laser surgery in patients with amenorrhea.

Thirty-eight postmenopausal women and one with pituitary amenorrhea underwent cervical laser surgery. The cervical canal of each patient was patent 2 weeks later. Eighteen of the 30 women reevaluated 4-48 months later had total obliteration of the cervical canal. In some patients, the cervix was obliterated and flush with the vaginal vault so that it could not be identified. Five other patients had severe cervical stenosis. Factors contributing to cervical os obliteration appeared to be the depth of the cervical defect, the lack of the physical action of blood passing through the cervical canal, and the hypoestrogenic state. This outcome makes continued adequate cytologic and colposcopic surveillance of these patients impossible and leaves them at risk for developing unrecognized cervical and endometrial disease.

Perimenopausal bleeding patterns and pathologic findings.

The charts of 500 sequential perimenopausal patients were reviewed and their alterations in menstrual flow were characterized as fitting one of three patterns. Sixty-two patients (12%) had sudden amenorrhea, 347 (70%) had oligomenorrhea and/or hypomenorrhea, and 91 (18%) had menorrhagia, metrorrhagia, and/or hypermenorrhea. All of the patients in the menorrhagia/metrorrhagia and/or hypermenorrhea group had histologic evaluations to rule out the presence of premalignant or malignant disease; 17 women (19%) in this group had premalignant or malignant findings. In addition, 4 of the 5 women with malignancies had intermenstrual bleeding. Of the 9 women in the study with intermenstrual bleeding, 4 had invasive cancer and 2 had endometrial hyperplasia. This study documents and highlights the high incidence of premalignant and malignant findings in perimenopausal patients with bleeding patterns other than amenorrhea or oligomenorrhea/hypomenorrhea, and underscores the need for perimenopausal women with menorrhagia, metrorrhagia, and/or hypermenorrhea to undergo thorough evaluation.

Adenofibroma of the uterus: multiple recurrences following wide local excision.

The uterine adenofibroma is a form of mixed mesodermal tumor in which both epithelial and stromal components are benign. A case is presented in which a patient with this lesion was treated with excision of the tumor rather than hysterectomy. Two years later, she developed a recurrence of the lesion, which was again treated with wide local excision. A hysterectomy was done 9 months later, and a polypoid lesion was noted in the fundus of the uterus which on histologic examination was thought to be potentially either an adenofibroma precursor or a maturation of the previous cellular adenofibroma. Since uterine adenofibroma usually occurs in older patients, the standard treatment has been hysterectomy. Because of this patient's age, she was initially treated with a more conservative approach. However, despite the fact that the uterine adenofibroma is a benign lesion, it has an obvious potential to recur when treated conservatively.

Teenagers' awareness of the acquired immunodeficiency syndrome and the impact on their sexual behavior.

One hundred female teenagers attending a teenage pregnancy program were studied to determine the extent of their awareness about acquired immunodeficiency syndrome (AIDS) and the impact of such knowledge on their sexual behavior. Ninety-eight knew that AIDS is a disease, 45 stated that it is fatal, and all knew that it can be transmitted by sexual intercourse. After becoming aware of AIDS, 59 changed their sexual habits, 41 decreased their number of sexual partners, and 13 who had not used condoms started using them. However, only seven obtained more information about their partners' sexual and social histories, and half of those who decreased their number of partners still continued relationships with more than one. The survey showed that the publicity about AIDS has resulted in a favorable change in the sexual practices of these teenagers. However, it also indicated a need for further improvement in specific areas of education, such as the value of obtaining more information about sexual partners, more awareness of the importance of multiple-partner relationships in the spread of AIDS, and more emphasis on the important role of condoms in preventing AIDS virus transmission.

The multicentric nature of disease related to human papillomavirus infection of the female lower genital tract.

Two hundred fifty-one consecutive patients from our colposcopy clinic were evaluated to establish the extent to which human papillomavirus (HPV) infection is a disease of the entire female lower genital tract. Colposcopic examinations and biopsies of the cervix and vulva were performed on all patients. Two hundred two women had cervical disease, of whom 164 (81%) also had vulvar disease. The percentage was the same regardless of the severity of the cervical disease. One hundred ninety-four of the patients had vulvar disease and of these, 164 (85%) also had cervical disease. Twenty-nine of 37 women (78%) with overt vulvar condylomata had cervical disease; 15 of these presented without a Papanicolaou smear, and 13 had cervical disease. We conclude that HPV infection of the female lower genital tract is a multicentric disease. All patients with evidence of HPV infection should undergo colposcopic evaluation of the entire lower genital tract. The significance that this will have on future attempts to cure this infection needs to be studied.

Comparison of the adrenocorticotropic hormone stimulation test with and without prior dexamethasone suppression in the diagnosis of congenital adrenal hyperplasia.

A comparison was made of the ACTH stimulation test with and without prior dexamethasone suppression in 10 patients, each of whom served as her own control. It was found that it is not necessary to administer DEX before the test, the specificity and sensitivity of both tests being the same in the diagnosis of CAH, although the calculated values are lower when DEX is given. Further investigation with HLA typing and ACTH stimulation testing is necessary to establish whether either or both types of ACTH stimulation tests are capable of discriminating between the heterozygotic and homozygotic varieties of CAH.
