Asymptomatic struma ovarii: a case report.

Struma ovarii is a rare ovarian neoplasm. This tumor is generally benign, although malignant transformation has been reported. The preoperative diagnosis is generally difficult. Thyroid hormones may be produced and in a few cases asymptomatic women may develop definitive clinical hypothyroidism after resection of struma ovarii. We report a case of a 39-year-old woman who underwent laparoscopic resection of an asymptomatic right ovarian mass. The pathologic diagnosis was struma ovarii. The postoperative period was uneventful and her thyroid function remained normal.

Reproductive outcome after laparoscopic treatment of endometriosis.

PURPOSE OF INVESTIGATION: To evaluate the pregnancy rate after laparoscopic treatment of endometriosis. PATIENTS AND METHODS: 47 infertile women undergoing laparoscopic treatment of endometriosis. RESULTS: rAFS stage was as follows: 11% of patients had Stage I, 11% Stage II, 53.3% Stage III and 24.4% Stage IV. The mean duration of follow-up was 48.5 +/- 18.44 months. The overall pregnancy rate was 64.4%. Eighteen out of 26 women (69%) became pregnant within six months after laparoscopy, 23% at 12 months, 11% within 24 months, and 11% after two years (p < 0.01). Adnexal adhesions and tubal status significantly affected the pregnancy rate. No differences were found regarding the stage of disease and the presence of ovarian endometriomas. CONCLUSION: Laparoscopic treatment of endometriosis enhances fertility and the pregnancy rate is highest within the first six months after surgery. Adnexal adhesions and tubal conditions influence the reproductive outcome.

Correlation between endometriosis and pelvic pain.

STUDY OBJECTIVE: To evaluate the relationship between prevalence and severity of chronic pelvic pain (CPP) and stage, site, and type of endometriosis. DESIGN: Prospective, observational study (Canadian Task Force classification II-2). SETTING: University Hospital. PATIENTS: Of 90 consecutive women with biopsy-proved endometriosis, laparoscopy was performed in 69 for pelvic pain and in 21 for infertility or clinical and ultrasonographic suspicion of ovarian endometriosis. INTERVENTION: Preoperatively, using a 10-point visual analog scale, the severity of dysmenorrhea, CPP, and deep dyspareunia was assessed. During laparoscopy all visible endometriotic lesions were recorded and treated. MEASUREMENTS AND MAIN RESULTS: Ten women (11.1%) had no pain; 72 had dysmenorrhea (mild in 13, moderate in 37, severe in 22); 55 had CPP (mild in 11, moderate in 25, severe in 19); and 39 deep dyspareunia (mild in 5, moderate in 31, severe in 3). The severity of dysmenorrhea significantly correlated with the presence and extent of pelvic adhesions (p = 0.004); the severity of CPP correlated with deep endometriosis on the uterosacral ligaments (p = 0.0001) and extent of pelvic adhesions (p = 0.02); and deep dyspareunia correlated with deep endometriosis on the uterosacral ligaments (p = 0.04). Total pain score significantly correlated with deep endometriosis on the uterosacral ligaments (p = 0.0001), peritoneal adhesions (p = 0.01), and extent of adnexal adhesions (p = 0.01). No significant correlation was found among revised American Fertility Society stage of endometriosis; presence and size of ovarian endometriomas; extent, type, and site of peritoneal lesions; and pain scores. By logistic regression analysis, the presence and intensity of total pain could be predicted simultaneously by the presence of deep endometriosis (p = 0.0001) and presence and extent of adnexal adhesions without cystic endometriosis (p = 0.01), and by the presence of ovarian endometrioma with periovarian adhesions (p = 0.03). Chronic pelvic pain was predicted by both deep endometriosis (p = 0.0001) and ovarian endometriomas with adnexal adhesions (p = 0.03). Deep dyspareunia was predicted simultaneously by deep endometriosis (p = 0.01) and an ovarian endometrioma with periovarian adhesions (p = 0. 008). Conclusion. Deep endometriosis, pelvic adhesions, and ovarian cystic endometriosis were independent predictors of pelvic pain. These data strongly suggest that it is not the size of ovarian cystic endometriosis but the association with adhesions that causes pelvic pain.

The biophysical/biochemical test. A new marker of fetal lung maturity in borderline cases.

OBJECTIVE: To assess the diagnostic accuracy of the combination of a biophysical (lamellar body count [LB]) with a biochemical test lecithin/sphingomyelin ratio (L/S) for the evaluation of fetal lung maturity (FLM) in cases of intermediate-borderline pulmonary maturity. STUDY DESIGN: We studied 105 cases with one or both intermediate (2.1-2.4:1 for L/S and/or 15,000-19,000/microL for LB) or borderline (2.5:1 for L/S and/or 20,000/microL for LB count) FLM indices and no phosphatidylglycerol who delivered within 72 hours of amniocentesis, excluding multiple gestation and contaminated amniotic fluid samples. The biophysical x biochemical marker (B x B) was calculated by multiplying L/S by the corresponding LB, then dividing by 10(3). By using the ROC curve, a cutoff of 50 was found. RESULTS: B x B values were lower in respiratory distress syndrome (RDS) than in the non-RDS group (30 [23-41] vs. 52 [50-70], P < .001; median, 25-75%). All RDS cases had a B x B value < 50. Diagnostic accuracy for B x B was: sensitivity, 100%; specificity, 83%; positive predictive value, 61%; negative predictive value, 100%. Sensitivity and positive predictive values were higher for B x B than L/S. CONCLUSION: B x B may be a useful tool for cases with borderline FLM.

The role of laparoscopy in the management of pelvic pain in women of reproductive age.

OBJECTIVE: To review the diagnostic and therapeutic roles of laparoscopy in women of reproductive age with acute and chronic pelvic pain. DATA IDENTIFICATION: Studies relating to the use of laparoscopy in women with acute and chronic pelvic pain were identified through the literature and MEDLINE searches. CONCLUSION(S): Laparoscopy has an important place in the management of conditions that cause acute pelvic pain in women of reproductive age, including ectopic pregnancy, pelvic inflammatory disease, tubo-ovarian abscess, and adnexal torsion. The procedure frequently facilitates the diagnosis and provides the necessary access for surgical treatment. Prompt diagnosis and effective management prevent complications and help preserve fertility. The role of laparoscopy in women with chronic pelvic pain is more controversial and limited, but abnormal laparoscopic findings are detected in approximately 60% of those who have undergone a multidisciplinary investigation and received a tentative clinical diagnosis. The access provided by laparoscopy permits the effective surgical treatment of many of the conditions encountered, including endometriosis, pelvic adhesions, ovarian lesions, and symptomatic uterine retroversion.

Comparison of local injection of methotrexate and linear salpingostomy in the conservative laparoscopic treatment of ectopic pregnancy.

STUDY OBJECTIVE: To compare local injection of metothrexate (MTX) and linear salpingostomy in the conservative laparoscopic treatment of ectopic pregnancy. DESIGN: Prospective, nonrandomized study, July 1991 to May 1994. SETTING: Department of obstetrics and gynecology in a university hospital. PATIENTS: Fourteen women with unruptured ectopic pregnancies without documented fetal heart motion and size below 50 mm as measured by ultrasound. INTERVENTIONS: All 14 women underwent the laparoscopic treatment by either local injection of MTX or linear salpingostomy (7 patients each). MEASUREMENTS AND MAIN RESULTS: Both treatments were successful in all patients. Mean length of operation was 32 +/- 5 minutes (range 25-35 min) in the MTX group versus 67 +/- 15 minutes (range 50-90 min) in the salpingostomy group. Mean length of hospital stay was 2.7 days (range 1-5 days) and 1.7 days (range 1-3 days), respectively. No intraoperative complications occurred, and the postoperative course was uneventful in all women. Mean disappearance time of serum beta-human chorionic gonadotropin (hCG) levels was similar in both groups, although in the linear salpingostomy group the decrease was immediate. No difference in tubal patency on follow-up hysterosalpingography was observed between the two groups. CONCLUSIONS: Although this is a preliminary report with a small number of patients, both types of treatment were safe and effective. An advantage of linear salpingostomy was the predictable and consistent decline of circulating beta-hCG, and consequently a reduced need for a close follow-up. Local MTX injection was safe, economic, effective, and easy to perform, and in our experience the surgical time was statistically shorter than that for linear salpingostomy. Therefore, in selected patients, local injection of MTX could be the treatment of choice for unruptured ectopic pregnancy, avoiding a longer and potentially more dangerous procedure. Long-term outcomes do not seem to differ between the two types of treatment.

Laparoscopic treatment of ovarian endometrioma. One year follow-up.

Thirty-six women with ultrasonographic diagnosis of ovarian endometrioma (bilateral in nine of them), have been treated laparoscopically. After the surgical procedure the patients were assigned to one of the following regimes: Gn-RH-a for 3 months, oral contraceptives if they wanted to avoid pregnancy, or nothing. The follow-up consisted in 1-3-6-12 months ultrasound. The first recurrences were observed at the 6-month ultrasound with an overall recurrence rate after 12 months of 11%. Improvement of pain symptoms occurred in 87% of the patients and fertility rate was 45%.

No evidence of the hook effect in peritoneal fluid CA 125 measurement using immunoenzymatic second generation assays: comparison with immunoradiometric assays.

OBJECTIVE: To monitor the occurrence of the hook effect in measurements of peritoneal fluid CA 125 levels using two different immunoenzymatic second generation assays (ETI-II and EIA-II), and to compare these results with those obtained using the respective immunoradiometric versions of the assays (IRMA-II and ELSA-II). STUDY DESIGN: CA 125 levels were determined in peritoneal fluid and serum samples obtained from 45 women with gynecological diseases. The assays were carried out using IRMA-II and ETI-II (Sorin Biomedica) and ELSA-II and EIA-II (CIS Bio International) assays. Occurrence of the hook effect and linearity of the assays were evaluated. Statistical analyses were performed by Wilcoxon's test and linear regression analysis. RESULTS: Undiluted peritoneal fluids, assayed for their CA 125 content, showed falsely underestimated values of the antigen when IRMA-II and ELSA-II assays were performed. The phenomenon disappeared only at high dilutions of the sample (> 50). Conversely, immunoenzymatic ETI-II and EIA-II assays performed on undiluted peritoneal fluids did not show underestimated CA 125 values. CA 125 values obtained by immunoenzymatic assay were lower than those obtained using their respective immunoradiometric versions at a dilution of 1:100 (P < 0.001). A good correlation was observed between ELSA-II and EIA-II (r = 0.929) CA 125 values. CONCLUSION: The EIA-II immunoenzymatic assay appears to be more suitable for CA 125 measurement in peritoneal fluid in that it is not subject to the hook effect and its results correlated well with those obtained via its immunoradiometric version.

Cervical stump carcinoma therapy.

59 patients with cervical stump cancer were reviewed. A distinction was made between true and coincident cancer. Histological features, therapeutic plan and survival rates are reported. In stage I treatment was mainly surgical, while in more advanced stages radiation therapy was applied. In 22.2% of cases combined surgical-radiation therapy was performed. The absolute 5-year survival for various clinical stages is as follows: stage I, 88.2%; stage II, 53.8%; stage III, 42.8%; stage IV, 0.0%. The overall absolute 5-year survival rate for all stages combined is 60.9%. Individualization of therapy can offer to the patient with cervical stump carcinoma a survival similar to the patient with cervical neoplasm with intact uterus.

Serum evaluation of P53 protein in patients with gynaecological cancer.

Sera from patients with gynaecological cancer including the ovary, endometrium or cervix were examined for p53 protein, using the Pantropic p53 quantitative ELISA. Patients with benign gynaecological pathologies were included as a control group. p53 values ranged from undetectable to high levels of the protein (range: 0-531 pg/ml). Using the value of 200 pg/ml as the cut-off, p53 serum levels were found to be elevated in 23% of the patients with ovarian cancer, in 16% of the patients with endometrial cancer and in 14% of the patients with cervical cancer. In the control group, increased serum p53 levels were found in 3.3% of patients. No differences were observed among the groups with different types of cancer or at different stages, but the differences between the cancer groups and the control group were statistically significant. Our results suggest that serum p53 evaluation could be an adjunctive tool to the diagnostic laboratory tests for preoperatively gynaecological cancers and both a competitive and alternative useful procedure for the detection of p53 gene mutations.
