Diagnostic inadequacy of dilatation and curettage.

OBJECTIVE: To assess the diagnostic inadequacy of dilatation and curettage (D&C) by comparing histologic findings with this technique with those obtained after hysterectomy. DESIGN: Retrospective clinical study. SETTING: University-affiliated hospital. PATIENT(S): Three hundred ninety-seven patients with abnormal uterine bleeding who underwent D&C and, within 2 months, hysterectomy because of histologic findings or persistence of symptoms. MAIN OUTCOME MEASURE(S): Comparison of histologic findings on D&C with those obtained after hysterectomy. RESULT(S): In 248 of 397 patients (62.5%), D&C failed to detect intrauterine disorders subsequently found at hysterectomy; the sensitivity was 46%, the specificity was 100.0%, the positive predictive value was 100.0%, and the negative predictive value was 7.1%. CONCLUSION(S): Dilatation and curettage is an inadequate diagnostic and therapeutic tool for all uterine disorders; this technique missed 62.5% of major intrauterine disorders, and all endometrial disorders were still present in the removed uterus.

Immunological markers in HIV-infected pregnant and non-pregnant women.

OBJECTIVE: To assess the influence of pregnancy on the course of HIV infection by comparing the behaviour of total lymphocyte counts and lymphocyte subsets (CD4(+) and CD8(+) and their ratio) in a cohort of infected pregnant women. SETTING: Tertiary referral centre for high risk obstetrics and infectious diseases in pregnancy. PATIENTS AND METHODS: A prospective study was designed, HIV infected women being enrolled at the beginning of pregnancy and sampled each trimester and in the puerperium. As controls, a group of non-pregnant HIV-infected women, cross-matched for age, risk factors and stage of disease were included and similarly evaluated in the same period. RESULTS: All the parameters, when longitudinally evaluated, were stable during gestation. Compared with non-pregnant subjects, patients had higher CD4(+) counts at the beginning and increased values of total lymphocytes count and subsets during the puerperium. Antepartum and postpartum risk factors such as drug abuse, smoking, antiretroviral therapy, length of gestation, maternal complications and HIV status of the neonate were not influential on the total lymphocytes counts and subsets. DISCUSSION: According to this data, pregnancy per se seems to have a negligible influence over the course of HIV infection, at least as far as immune parameters are concerned.

Sonographic, hysteroscopic, and histologic evaluation of the endometrium in postmenopausal women with breast cancer receiving tamoxifen.

STUDY OBJECTIVE: To evaluate the estrogenic effects of tamoxifen on the endometrium in postmenopausal women with breast cancer. DESIGN: Consecutive study (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. PATIENTS: Thirty-three women. Interventions. All patients underwent transvaginal sonography (TVS) and color flow Doppler of endometrial vessels, hysteroscopy, and, if necessary, endometrial biopsy or other operative hysteroscopic procedures. MEASUREMENTS AND MAIN RESULTS: In four women the endometrium was thin on TVS and atrophic at hysteroscopic assessment. In 29 women with thick endometrium on TVS, hysteroscopy and endometrial biopsy showed atrophy (11 patients), hyperplasia (5), polyps (11), and well-differentiated adenocarcinoma (2). The two endometrial cancers were present in women with uterine bleeding. In women with positive histologic findings, the endometrium was significantly thicker (p = 0.04) and duration of tamoxifen therapy longer than in those with negative findings, although this was not statistically significant (p = 0.067). CONCLUSION: We believe regular assessment of the endometrium by TVS should be performed in postmenopausal patients at the start of the tamoxifen therapy, and hysteroscopy in women with a thick endometrium or postmenopausal bleeding. We believe that patients with thin endometrium on TVS at the beginning of tamoxifen therapy, who have no abnormal uterine bleeding should be screened with these examinations for 2 years.

Hysteroscopic evaluation of the endometrium in postmenopausal women taking tamoxifen.

STUDY OBJECTIVE: To evaluate hysteroscopic endometrial changes due to tamoxifen therapy in postmenopausal women with breast cancer. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. Patients. Eighty-eight postmenopausal women (or with iatrogenic amenorrhea) receiving tamoxifen 20 mg/day for at least 1 year for breast cancer. INTERVENTION: Record review of patients undergoing transvaginal sonography (TVS) and office hysteroscopy with eye-directed biopsy specimens obtained with a 5-mm, continuous-flow, operative hysteroscope. MEASUREMENTS AND MAIN RESULTS: Patients with thickened endometrium and pathologic findings at hysteroscopy had taken tamoxifen for significantly longer times than those without such findings (p < 0.05). CONCLUSION: Our findings confirm the estrogenic effect of tamoxifen on endometrium. Endometrial evaluation by TVS suggests further diagnostic procedures, but only hysteroscopy allows the surgeon to visualize endometrial lesions and obtain eye-directed biopsy tissue.

Hysteroscopic evaluation of menopausal women with endometrial thickness of 4 mm or more.

STUDY OBJECTIVE: To assess the diagnostic and operative potential of hysteroscopy in postmenopausal patients selected by ultrasound criteria. DESIGN: Cohort study (Canadian Task Force classification II-2). SETTING: Outpatient ultrasound and hysteroscopy department of a university-affiliated hospital. PATIENTS: One hundred fifty-five postmenopausal women with endometrial thickness of 4 mm or more by ultrasound, in menopause for at least 1 year, with or without menopausal complaints. INTERVENTIONS: Transvaginal ultrasound and office hysteroscopy with eye-directed biopsy specimens using a 5-mm, continuous-flow, operative hysteroscope. MEASUREMENTS AND MAIN RESULTS: Of the 155 women, 129 (83%) were asymptomatic (irregular bleeding). Hysteroscopy showed endometrial pathology in 28% of asymptomatic patients (23 polyps, 5 cases of hyperplasia, 8 submucous myomata) and 76% of symptomatic women (13 polyps, 6 hyperplasia, 1 submucous myoma). Hysteroscopic results compared with histologic diagnosis showed a positive predictive value equal to 97. 1% and 95% in asymptomatic and symptomatic women, respectively, and a negative predictive value equal to 100% in both groups. CONCLUSION: Office hysteroscopy with endometrial biopsy samples has a diagnostic and operative role in postmenopausal patients selected based on endometrial thickness on ultrasound, in view of the high prevalence of endometrial pathology in both symptomatic and asymptomatic women.

Hysteroscopic evaluation of menopausal patients with sonographically atrophic endometrium.

STUDY OBJECTIVE: To assess the diagnostic and operative potential of hysteroscopy in postmenopausal patients selected by ultrasound criteria. DESIGN: Prospective evaluation (Canadian Task Force classification II-2). SETTING: Outpatient ultrasound and hysteroscopy department of a university-affiliated hospital. PATIENTS: Two hundred twelve women with an endometrial thickness less than 4 mm on ultrasound and in menopause for at least 1 year. INTERVENTIONS: Transvaginal ultrasound and office hysteroscopy, with eye-directed biopsy specimens obtained with a 5-mm, continuous-flow operative hysteroscope, and performed without anesthesia. MEASUREMENTS AND MAIN RESULTS: Only 13 (6%) patients were symptomatic (irregular bleeding). Hysteroscopic diagnosis of endometrial polyps in three women (23%) was confirmed by histology. In the remaining 199 (94%) asymptomatic patients with atrophic endometrium on ultrasound, hysteroscopy showed an endometrial pathology in 10% (16 polyps, 4 submucous myomas); in one patient histologic evaluation disclosed focal adenocarcinoma in an endometrial polyp. CONCLUSION: Hysteroscopy allows a proper histologic diagnosis, even in asymptomatic postmenopausal women with atrophic endometrium on ultrasound.

Endoscopic examination of the fetus in early pregnancy.

OBJECTIVE: To assess if fetal examination is feasible by endoscopy in the late first-early second trimester. SETTING: Tertiary referral center for high risk obstetrics and genetics. PATIENTS AND METHODS: Patients (total number 9) submitted to pregnancy termination for social reason (7) or for chromosomal abnormality (2) between 10 and 14 weeks of pregnancy. Visualisation of the foetus by a transabdominally introduced endoscope (19 gauge) under local anaesthesia. Step by step examination of the foetal contour and double check of the recordings by a senior Pathologist. RESULTS: Patients complained no serious discomfort. Visualisation was accomplished in all cases with ease and the images were judged satisfactory by the Pathologist. Fetal examination was found easier at 10-12 weeks of gestation rather than at 13-14 weeks. DISCUSSION: Endoscopy is a simple and well tolerated procedure, which enables precise visualization of external fetal anatomy as early as the first trimester of gestation. Therefore it can be proposed before surgical termination of pregnancy.

Legionnaire's disease complicating pregnancy: a case report with intrauterine fetal demise.

OBJECTIVE: Legionnaire's disease complicating pregnancy is an unusual event that can seriously compromise both the mother and the fetus. CASE REPORT: We describe one case of such association, with an unfavourable intrauterine fetal outcome, secondary to acute placental insufficiency, related to infection. DISCUSSION: It is important in these high risk pregnancies complicated by acute pneumonia to take into consideration the diagnosis, as early as possible, and the appropriate treatment or the careful monitoring of fetal wellbeing.

Predictive value of serum androstenedione basal levels on the choice of gonadotropin or laparoscopic ovarian electrocautery as ovulation induction in clomiphene citrate-resistant patients with polycystic ovary syndrome.

Therapeutic approaches to chronic anovulation from polycystic ovaries in clomiphene-resistant infertile patients are under debate. This study discusses evidence that supports the possible predictive value of serum basal level of androstenedione in the choice of the better therapy between laparoscopic ovarian electrocautery and ovulation induction. Lower androstenedione levels seem to be correlated with a better ovarian response after ovulation induction with gonadotropins, while high androstenedione levels are associated with a higher incidence of conception after laparoscopic ovarian electrocautery. Obesity does not seem to represent a hindrance to laparoscopic treatment.

Transvaginal sonography and hysteroscopy in postmenopausal uterine bleeding.

OBJECTIVE: To compare the diagnostic accuracy of transvaginal ultrasound and hysteroscopy in the detection of endometrial pathologies in women with postmenopausal bleeding not using hormonal replacement therapy (HRT). METHODS: Between January 1997 and April 1998, 106 postmenopausal women with uterine bleeding not using HRT underwent a diagnostic work-up including pelvic examination, transvaginal ultrasound, hysteroscopy and endometrial biopsy. Sonographic measurement of endometrial thickness and hysteroscopic findings were compared with histological results. The 'classification tree' method was used to identify cut-off values of sonographic endometrial thickness that could be indicative of a class of uterine pathology. Statistical analysis was performed with the McNemar test. RESULTS: No case of endometrial cancer was found with a cut-off point of 5 mm of endometrial thickness evaluated by ultrasound, whereas all patients with endometrial thickness > or = 15 mm at sonography had an endometrial carcinoma. In the group of patients with endometrial thickness between 6 and 14 mm, we found normal atrophic endometria, benign and malignant pathology. On the other hand, the McNemar test showed a very good correspondence between hysteroscopy and histology (sensitivity 97.5% and specificity 100%), confirming its usefulness in diagnosis of postmenopausal uterine bleeding. CONCLUSIONS: Transvaginal ultrasound has revealed some limitations, mainly in the group of patients with endometrial thickness between 6 and 14 mm. The absence of endometrial malignancy in women with endometrial thickness < or = 5 mm and the high possibility of cancer in those with endometrial thickness > or = 15 mm should be confirmed in larger series. Hysteroscopy proved to be a simple and safe outpatient procedure with a high diagnostic accuracy, and in our opinion it should be considered in all women with postmenopausal uterine bleeding.

Surgical treatment of recurrent ovarian cancer: report of 21 cases and a review of the literature.

AIM: To evaluate the role of secondary cytoreductive surgery in patients with recurrent ovarian cancer. PATIENTS AND METHODS: A retrospective chart review was conducted on 21 patients submitted to secondary cytoreductive surgery for apparently isolated and resectable recurrence of ovarian cancer, after a disease-free interval of at least 12 months. RESULTS: Fifteen patients (71%) had complete surgical debulking with no macroscopic tumor at the completion of the surgical procedure. Eight patients (38%) required an intestinal resection but no colostomy was performed. Eleven complications were recorded in nine patients, but no operative death occurred. The median survival time for all patients after diagnosis of recurrent disease was 29 months (range 6-96 months). Survival time after diagnosis of recurrence was not significantly related either to known prognostic factors of ovarian cancer or to the length of the clinical remission time. The absence of residual disease after salvage surgery was the only factory associated with prolonged survival. CONCLUSION: Secondary cytoreductive surgery is a safe procedure which should be offered to recurrent ovarian cancer patients with apparently isolated and resectable disease, and without ascitis.

A vaginoscopic approach to reduce the pain of office hysteroscopy.

We developed a new approach to diagnostic hysteroscopy that reduces patient discomfort and increases the possible applications of hysteroscopy. Between February 1992 and March 1996, 1200 hysteroscopies were performed at our institution. Of these, the last 680 were done using the vaginoscopic approach without preselection. Discomfort was reduced in all patients, including those with moderate stenosis of the internal cervical os. Vaginoscopy is easy to perform and incurs no additional cost for the patient. It is ideal for office hysteroscopy and in patients who otherwise might require general anesthesia, such as virgins and older women with somewhat stenotic vaginas.

Missed hysteroscopic detection of uterine carcinoma before endometrial resection: report of three cases.

Endometrial ablation or resection using hysteroscopy appears to be an effective treatment for menorrhagia resistant to medical therapy. Three patients with endometrial adenocarcinoma missed in the preoperative hysteroscopic and histological assessment and subjected to endometrial resection were collected in a multicenter study. One case was an early adenocarcinoma in the background of late proliferative endometrium in a 39-year-old woman. In the other two patients, ages 51 and 68, the adenocarcinoma developed in a polyp in a background of simple hyperplasia. Since hysteroscopy with endometrial biopsy might not be able to exclude the presence of an early intrauterine cancer, appropriate selection and accurate evaluation of patients are imperative before ablative surgery. Endometrial resection is preferred over endometrial laser ablation since it provides additional tissue for histologic examination.

Diagnostic accuracy of hysteroscopy in endometrial hyperplasia.

OBJECTIVES: To determine the diagnostic accuracy of hysteroscopy in the diagnosis of endometrial hyperplasia in women with abnormal uterine bleeding. METHODS: From 1993 through 1995, 980 women referred to our institution for abnormal uterine bleeding underwent diagnostic hysteroscopy with eye direct biopsy of the endometrium in case of macroscopic abnormalities. Hysteroscopic features were compared with pathologic findings in order to detect the reliability of the endoscopic procedure. Statistical analysis was performed with the McNemar test. RESULTS: Positive predictive value of hysteroscopy in the diagnosis of endometrial hyperplasia accounted for 63%. In fact hysteroscopic diagnosis of endometrial hyperplasia was confirmed at pathologic examination in 81 out of 128 patients. Sensitivity and specificity of the endoscopic procedure accounted for 98% and 95%, respectively. Negative predictive value accounted for 99%, as only two cases of atypical hyperplasia were missed at hysteroscopy. Positive predictive value was higher in postmenopausal patients compared to women in the fertile age (72 vs. 58%). CONCLUSIONS: Overall, results appear encouraging, since no case of endometrial hyperplasia was missed by hysteroscopy. The high diagnostic accuracy, associated with a minimal trauma, renders hysteroscopy the ideal procedure for both diagnosis and follow-up of conservative management of endometrial hyperplasia.

The role of contact hysteroscopy.

Contact hysteroscopy has been replaced by a new technique based on the use of a special hysteroscope. The instrument was designed to study the squamocolumnar junction and the lesions of the portio. A new technique, endometrial dating, uses the Hamou hysteroscope to study endometrial physiology. We improved endometrial dating and discovered a new pattern, the pseudofunctional dysvascular endometrium (PFDE), that seemed to pertain to uterine bleeding. We also studied the PFDE syndrome in the presence of dysfunctional uterine bleeding. In this study we reviewed the three procedures and assessed their results. We conclude that contact microhysteroscopy is a reliable diagnostic procedure, and should be considered part of diagnostic hysteroscopy, not an independent technique.

Hyperplastic Human Endometrium

Endometrial hyperplasia is considered to be a frequent cause of menorrhagia. Traditionally, this pathology was diagnosed from specimens obtained by uterine curettage or after hysterectomy for benign disease. With hysteroscopy one can visualize the uterine cavity directly and perform guided biopsies of the endometrial mucosa. We assessed the reliability of hysteroscopic procedures in the diagnosis of endometrial hyperplasia. We performed 980 hysteroscopies in 3 years for menorrhagia and found endometrial hyperplasia in 128 women. We compared the results with histologic findings. Statistical analysis was performed according to McNemar test. On the basis of the results, hysteroscopy diagnoses and monitors endometrial hyperplasia.
