Thymosin beta-10 gene overexpression is a general event in human carcinogenesis.

The beta-thymosins comprise a family of structurally related, highly conserved acidic polypeptides, originally isolated from calf thymus. Recently, we have demonstrated the overexpression of thymosin beta-10 (TB10) in rat thyroid transformed cell lines and in human thyroid carcinoma tissues and cell lines. To verify whether TB10 overexpression is a general event in the process of carcinogenesis, we have analyzed TB10 mRNA levels in human colon carcinomas, germ cell tumors of different histological types, breast carcinomas, ovarian carcinomas, uterine carcinomas, colon and esophageal carcinoma cell lines. Overexpression of the TB10 gene was detected in all of the neoplastic tissues and cell lines compared to the respective normal tissues. Moreover, the mouse model of skin carcinogenesis induced by the combined action of chemical carcinogens and phorbol esters was used to identify the stage of TB10 gene induction. The expression was almost undetectable in normal keratinocytes, its induction occurred even at the papilloma stage, however a further increased expression was observed in the carcinoma derived cell lines. Finally, immunohistochemical analysis of some breast, colon and ovary carcinoma samples by using specific anti-TB10 antibodies revealed the presence of the TB10 protein in all of the neoplastic tissues, but not in the respective normal tissues. Therefore the TB10 detection may be considered a potential tool for the diagnosis of several human neoplasias.

Pain mapping during minilaparoscopy in infertile patients without pathology.

STUDY OBJECTIVE: To draw a map of pelvic pain and quantify the level of provoked pain during minilaparoscopy under local anesthesia and conscious sedation. DESIGN: Observational study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: Twenty infertile women. INTERVENTIONS: Minilaparoscopy was performed under local anesthesia and conscious sedation, and cognitive performance was evaluated with the Rey auditory verbal learning task. MEASUREMENTS AND MAIN RESULTS: The diagnostic procedure was performed with one 2-mm micrograsper and one 2-mm microprobe to evaluate the pelvis. In particular we grasped utero-ovarian ligaments; we touched, grasped, and distended fallopian tubes with blue dye; we moved the uterus with a manipulator inserted at the cervix; and we touched and grasped bowel and omentum. Level of pain was recorded on a visual analog scale. Patients had no pathologic findings, including minimal endometriosis and pelvic adhesions. The highest level of pain was recorded when we distended the tubes. No pain was elicited when we touched and grasped ovary, omentum, and bowel. In 10% of women when we stretched the tubo-ovarian ligament we provoked a minimal vagal reaction. CONCLUSION: Minilaparoscopy under conscious sedation for pelvic pain mapping in women without pain or pathology revealed consistently negative findings, validating the value of this measurement.

Pregnancies after activated oocyte transfer: a new option for infertility treatment.

In this preliminary report, we describe a new technique involving the same-day transfer of activated oocytes to the uterus after intracytoplasmatic sperm injection (ICSI). The technique, termed activated oocyte transfer (AOT), offered to 19 couples, yielded a pregnancy rate per cycle of about 30%, equivalent to traditional in-vitro fertilization (IVF) and ICSI in a laboratory setting. AOT is performed 4 h after oocyte retrieval, permitting the patient to undergo treatment as an out-patient procedure.

Topical anesthesia for office hysteroscopy. A prospective, randomized study comparing two modalities.

OBJECTIVE: To compare the efficacy of two modalities of local anesthesia for diagnostic hysteroscopy in different steps of the procedure in terms of pain control and time required for the examination. STUDY DESIGN: One hundred eighty women undergoing diagnostic hysteroscopy were included in the study and randomly allocated to one of two groups. Group A (n = 88), treated with prilocaine plus lidocaine cream, and group B (n = 92), treated with lidocaine spray, were compared with group C, a control group (n = 165), including all the hysteroscopies performed without anesthesia in the same period. Duration of the hysteroscopic examination was recorded; intensity of pain induced by the procedure and shoulder pain 10 minutes after the end of the examination were recorded for all patients on the basis of a four-point pain scale. RESULTS: Duration of the procedure required was two minutes in a significantly lower percentage of patients in group A as compared to groups B and C. Furthermore, in group A we found a significant reduction in pain at placement of the tenaculum in comparison to groups B and C. In groups A and B, no patient experienced a "very painful" grade of pain versus 4.8% in group C. The vasovagal reaction rate was also significantly lower in both treated groups in comparison to the control group. Furthermore, the intensity of shoulder pain was significantly lower in the group receiving prilocaine plus lidocaine cream as compared to the other two groups. CONCLUSION: Local anesthesia has a beneficial effect, at least in those hysteroscopies presumed to be, for whatever reasons, more cumbersome to perform. Prilocaine plus lidocaine cream was more effective than lidocaine spray in decreasing pain at placement of the tenaculum and shoulder pain after the procedure.

A prospective randomized study to evaluate leuprolide acetate treatment before laparoscopic myomectomy: efficacy and ultrasonographic predictors.

OBJECTIVE: Aims of our study were as follows: (1) to evaluate the therapeutic efficacy of the preoperative administration of a gonadotropin-releasing hormone analog before laparoscopic myomectomy and (2) to assess whether any ultrasonographic parameter of the fibroids (number, size, Doppler velocimetry, or echogenicity) was of prognostic value. STUDY DESIGN: A prospective randomized study was performed on 67 patients with symptomatic uterine fibroids that were mainly intramural; these patients were undergoing laparoscopic myomectomy. Patients were randomized either to preoperative administration of two injections of a depot formulation of leuprolide acetate 28 days apart (group A, n = 35) or to direct surgery (group B, n = 32). In each group we studied the number, volume, and echogenicity of the larger fibroids; the resistance index of uterine arteries and of fibroid vessels; hematologic parameters; operative time; and blood loss. RESULTS: The two groups did not differ significantly in basal ultrasonographic parameters and hematologic data. Postoperatively, the red blood cell count and the serum hemoglobin and iron levels were significantly (p < 0.05) lower in group B. Both blood loss (p < 0.01) and operative time (p < 0.05) were significantly lower in group A. However, the operative time was significantly longer when the main fibroid was markedly hypoechoic, probably because the increased softness of the tumor after leuprolide acetate pretreatment makes its enucleation much more cumbersome. CONCLUSION: Our data confirm the therapeutic efficacy of preoperative administration of a gonadotropin-releasing hormone analog before laparoscopic myomectomy in reducing the blood loss and in decreasing the operative time. This preoperative course of leuprolide acetate in hypoechoic fibroids, because of the further reduction of the density of the myomas, causes a significant (p < 0.05) increase in operative time.

Postoperative pain control after microlaparoscopy in patients with infertility: a prospective randomized study.

OBJECTIVE: To evaluate the efficacy of intraperitoneal subdiaphragmatic instillation of lidocaine and trocar site infiltration of bupivacaine to minimize postoperative pain after diagnostic microlaparoscopy performed under local anesthesia with conscious sedation. DESIGN: Prospective randomized study. SETTING: Day-surgery unit of Endogyn Service, Naples, and Department of Gynecologic and Pediatric Sciences, Reggio Calabria University, Catanzaro, Italy. PATIENT(S): Sixty-one women with infertility. INTERVENTION(S): All patients received local anesthesia and conscious sedation before surgery. After the microlaparoscopy, the treatment group was given 40 mL of intraperitoneal subdiaphragmatic 0.5% lidocaine and 5 mL of 0.5% bupivacaine that was infiltrated into the trocar insertion sites. The control group received no treatment. When necessary, ketoprofene or ketorolac were administered IM after surgery. MAIN OUTCOME MEASURE(S): Postoperative pain was evaluated with the use of a visual analog scale with scores ranging from 1-10 immediately after surgery and over the next 48 hours. The rate at which patients were discharged from the hospital 2 hours after surgery also was recorded. RESULT(S): The treatment group had significantly lower pain scores both immediately after surgery and 1, 3, and 6 hours afterward. The need for postoperative analgesics also was significantly lower in the treatment group. The rate at which patients were discharged 2 hours after surgery was significantly higher in the treatment group. CONCLUSION(S): Postoperative intraperitoneal lidocaine administration and bupivacaine infiltration of the trocar sites is beneficial for patients undergoing microlaparoscopy. The effect of these drugs is temporary, but they can significantly decrease postoperative pain for approximately 6 hours and reduce the need for additional analgesics. Most important, the rate at which patients can be discharged from the hospital only 2 hours after surgery is increased significantly.

Ultrasonographic prediction of the efficacy of GnRH agonist therapy before laparoscopic myomectomy.

STUDY OBJECTIVE: To assess ultrasonographic prediction of the efficacy of administration of a gonadotropin-releasing hormone (GnRH) analog before laparoscopic myomectomy. DESIGN: Prospective, randomized study of women treated consecutively from September 1994 to July 1996 (Canadian Task Force classification I). SETTING: Endogyn Service, Private Endoscopic Associates, Naples, and Department of Gynecologic and Pediatric Sciences, Reggio Calabria University, Catanzaro, Italy. PATIENTS: Sixty-seven infertile women with symptomatic uterine myomata, mainly intramural, undergoing laparoscopic myomectomy. INTERVENTIONS: Patients were prospectively randomized in two groups. Group A received preoperative administration of two injections of a depot formulation of leuprolide acetate 28 days apart, and group B underwent direct surgery. In each group we studied the number, diameter, and echogenicity of larger fibroids; resistance index of uterine arteries and myoma vessels; operating time; and blood loss. MEASUREMENTS AND MAIN RESULTS: The two groups did not significantly differ in baseline ultrasonographic parameters. Both blood loss (p <0.01) and operating time (p <0.05) were significantly lower in group A. However, operating time was significantly longer when the main myoma was markedly hypoechoic. CONCLUSION: Our data confirm the therapeutic efficacy of administration of a GnRH analog before laparoscopic myomectomy in reducing blood loss and decreasing operating time in all cases except those with markedly hypoechoic fibroids.

Pain control after microlaparoscopy.

STUDY OBJECTIVE: To evaluate the efficacy of intraperitoneal subdiaphragmatic instillation of 0.5% lidocaine and 0.5% bupivacaine infiltration of cannula sites to control pain after diagnostic microlaparoscopy. DESIGN: Prospective, randomized study. (Canadian Task Force classification I). SETTING: Day surgery unit of Endogyn Service, Private Endoscopic Associates, Naples, and Department of Gynecologic and Pediatric Sciences, Reggio Calabria University, Catanzaro, Italy. PATIENTS: Forty women treated for infertility. INTERVENTIONS: The treated group received 0.5% intraperitoneal subdiaphragmatic lidocaine 40 ml and 0.5% bupivacaine 5 ml infiltration of cannula insertion sites. The control group received no treatment. In all patients the procedure was performed with atropine 0.5 mg, fentanyl 0.1 mg, droperidol 5 mg, and local anesthesia. Postoperatively, depending on the need, ketoprofene 100 mg or ketorolac 30 mg was administered intramuscularly. MEASUREMENTS AND MAIN RESULTS: Postoperative pain score was evaluated by visual analog scale immediately postoperatively and 1, 3, 6, 12, 24, 36, and 48 hours afterward. The treated group had significantly lower pain scores at the end of surgery and at 1-, 3-, (p <0.01), and 6-hour intervals (p <0.05). No significant differences in scores between groups were observed starting from 6 hours postoperatively. CONCLUSION: Postoperative intraperitoneal lidocaine and bupivacaine infiltration of cannula sites offered a detectable benefit to women undergoing diagnostic microlaparoscopy. The effect was temporary, but induced a significant decrease in the postoperative pain for approximately 6 hours.

Prenatal diagnosis of congenital granular cell epulis.

Congenital granular epulis is a benign tumor that has rarely been diagnosed prenatally, although there have been numerous reports on its postnatal diagnosis. We report a case of large granular epulis diagnosed at 31 weeks' gestation in a woman whose previous anomaly scan had been normal. The lesion was 2.5 cm in diameter, pedunculated, and arose from the maxilla. It was completely surgically removed following preterm vaginal birth and histologically examined. The tumor did not prevent deglutition of the amniotic fluid and did not interfere with feeding or respiration, but prevented complete closure of the lips. We discuss the fetal management and the theories of histogenesis, and highlight the importance of early diagnosis and treatment.

In vitro fertilization following laparoscopic ovarian diathermy in patients with polycystic ovarian syndrome.

BACKGROUND: To evaluate the in vitro fertilization outcome in patients with polycystic ovarian syndrome previously treated by laparoscopic ovarian diathermy. METHODS: We designed a prospective study to compare in vitro fertilization stimulation parameters and pregnancy rate for two groups of women with polycystic ovarian syndrome. In the first group, we included 23 patients previously treated by laparoscopic ovarian electrodiathermy (group A), in the second group we included 36 women who did not undergo surgical treatment (group B). All patients underwent the same ovarian hyperstimulation protocol and a standard in vitro fertilization and embryo transfer technique. In a limited number of women (five in group A and eight in group B) we measured the levels of sex steroids in follicular fluid. Statistical analysis was performed by means of chi-square test or Fisher's exact test to compare frequencies and by means of the Student's t-test or ANOVA test to compare means. Significance was set at p < 0.05. RESULTS: In group A we found a significantly higher ongoing pregnancy rate (28.6% in group A vs 7.3% in group B), a significantly lower estradiol peak level (1722.73 +/- 522.24 in group A vs 2314.48 +/- 692.60 in group B), a trend for lower abortion rates and an improvement in the number of patients administered human chorionic gonadotropin than in group B. The levels of estradiol, testosterone and androstenedione in follicular fluid were significantly lower from small to intermediate and to large follicles in group A, while in group B only estradiol and androstenedione were different. Lower levels of androstenedione and testosterone were found in each follicular pool of group A, compared to the respective pool in group B. CONCLUSION: We report a significantly better ongoing pregnancy rate after in vitro fertilization and embryo transfer procedures in women pretreated by means of laparoscopic ovarian electrocautery. These results may be related to lower androgen levels in the follicular fluid.

Late complications after systemic methotrexate treatment of unruptured ectopic pregnancies: a report of three cases.

BACKGROUND: The use of methotrexate (MTX) by systemic administration in the treatment of unruptured ectopic pregnancy has been reported as a safe and effective method. CASES: We report three cases (one hematosalpinx and two pelvic hematocoeles) of complications after the use of MTX in the treatment of unruptured ectopic pregnancies. All three cases came to our observation for pelvic pain, abnormal bleeding and a pelvic mass after an interval of 3-5 months, subsequent to the disappearance of symptoms and normalization of serum human chorionic gonadotropin beta-subunit (beta-hCG) levels. CONCLUSIONS: These findings suggest that: (a) such complications should be considered before selecting the mode of treatment for ectopic pregnancy; and (b) that an early ultrasonographic control should be performed after MTX treatment even when the decline in beta-hCG levels suggests a successful resolution. This would permit an early diagnosis of these late complications.

A risk model for ovarian carcinoma patients using CA 125: time to normalization renders second-look laparotomy redundant.

BACKGROUND: We evaluated the incorporation of CA 125 normalization times into a prognostic model based on pretreatment variables in patients with ovarian carcinoma to determine if they could render second-look laparotomy (SLL) redundant. METHODS: A total of 54 consecutive patients with ovarian carcinoma who underwent SLL between 1985 and 1990 were included in this analysis. At diagnosis, all of the patients had abnormal CA-125 serum levels, which fell to within the normal range during chemotherapy. Cox's model was used to select pretreatment variables relevant for prognosis. The influence of the time to normalization of CA 125 (< or = vs. > 1 months) and the capability of SLL results to modify prognostic prediction, were also evaluated. RESULTS: The size of the residual tumor at the beginning of therapy, and Eastern Cooperative Oncology Group (ECOG) performance status (PS) were independently predictive of survival. The time to normalization of CA 125 serum levels (analyzed either as -a continuous or as a two-category variable) also had an independent prognostic role when included in the model. When we examined the inclusion of both CA 125 parameter and SLL into the model together, we found that only CA 125 continued to have an independent prognostic relevance. On the basis of the two pretreatment parameters (PS and tumor size) and of this response parameter (time to normalization of CA 125 values) we selected six subgroups of patients having different outcomes (log rank test of equality over-strata < 0.001). Patients with good prognostic pretreatment variables, and those with intermediate prognosis at the beginning of therapy who showed a quick normalization of CA 125, had an 80% 5-year survival, compared with 16% 5-year survival in the remaining patients. (P < 0.0001). CONCLUSIONS: Our data suggest that the survival of patients with advanced ovarian carcinoma could be accurately predicted by considering some pretreatment variables and time to CA 125 normalization together, without performing SLL. Our risk model, however, needs to be validated by larger prospective trials, to draw any definitive conclusions about the abandonment of surgically defined response.

Identification of differentially expressed mRNAs in normal and neoplastic (adenocarcinoma) human endometrium.

Individual mRNA species from normal and neoplastic endometrium obtained from the same patient were comparatively studied by exploiting the "differential display" methodology. The mRNAs were extracted from tissues, reverse transcribed, and amplified by PCR using appropriate primers. The cDNA electrophoretic bands which were frankly different on the basis of their quantitative expression were excised from the gels and reamplified. Each of these sequences was subsequently screened for the capacity to hybridize to RNA preparations from normal endometrium and endometrial adenocarcinoma samples, first from the original patient and then from a group of selected patients. Of many, only two sequences, thereafter named N5.5 and T16.2, respectively, successfully passed the two sieving tests and were chosen for further analysis. It appears that N5.5 recognizes an mRNA which is expressed more abundantly in normal than in neoplastic (adenocarcinoma) endometrium; in contrast, T16.2 seems to preferentially recognize an mRNA which is expressed in tumoral tissues. These two sequences have been cloned and sequenced; they do not show any identity or significant similarity to any other known sequence.

Fetal fibronectin as a screening test for premature delivery in multiple pregnancies.

OBJECTIVE: To evaluate fetal fibronectin as a screening test for premature delivery in asymptomatic women with multiple pregnancies. METHODS: In the mid-second trimester, the concentrations of fetal fibronectin in the cervical and vaginal secretions of 68 patients with multiple gestations were sampled weekly by monoclonal antibody immunoassay in order to predict preterm labor. RESULTS: The results for the prediction of preterm labor differ according to whether we consider a single positive result (fetal fibronectin > 50 ng/ml) as predictive of preterm labor or whether we only consider at least two consecutive positive results as predictive of perterm labor. The fetal fibronectin test had a sensitivity for preterm birth before 37 weeks of 90.9% and 86.6%, respectively, with a specificity of 68.5% vs. 78.9% and a positive and negative values of 73.1% vs. 76.4% and 88.8% vs. 88.2%, respectively. Similar results were obtained for perterm birth before 34 weeks. CONCLUSIONS: In a condition such as multiple pregnancy which is already at risk for premature delivery the possibility of raising the specificity of the test with virtually no decrease in sensitivity guarantees better recognition of patients likely to develop premature labor. This possibility can be achieved simply by considering two positive consecutive samples as predictive of preterm labor.

Superovulation with urinary human follicle-stimulating hormone: correlations with body mass index and body fat distribution.

Our objective was to investigate the relationship between body mass index (BMI), waist/hip ratio (WHR), follicle-stimulating hormone (FSH) dose, length of stimulation and clinical outcome in infertile women with and without polycystic ovary syndrome (PCOS) undergoing controlled ovarian hyperstimulation. Controlled ovarian hyperstimulation was induced in 60 women for a total of 111 cycles (48% in PCOS patients) with urinary human FSH (u-hFSH). A significant correlation between BMI, u-hFSH dose and duration of stimulation was found in PCOS and non-PCOS patients with WHR < 0.8. These correlations were not present in PCOS patients with WHR > 0.8. Pregnant patients received significantly less ampules of u-hFSH. From our data we suggest a controlled ovarian hyperstimulation protocol, for obese non-PCOS patients and obese PCOS patients with WHR < 0.8, starting with a double dose of u-FSH.

Carboplatin (CBDCA)-hexamethylmelamine (HMM)-oral etoposide (VP-16) first-line treatment of ovarian cancer patients with bulky disease: a phase II study.

Hexamethylmelamine (HMM) and oral etoposide (VP-16) have shown to be active against platinum-resistant epithelial ovarian cancer. On this basis a three-drug regimen including carboplatin (CBDCA) plus HMM and oral VP-16 was tested in previously untreated ovarian cancer patients with tumor size > 2 cm. Since October 1991, 29 chemotherapy-naive ovarian cancer patients with tumor larger than 2 cm (20 stage III and 9 stage IV) have been treated for a total of 153 courses. CBDCA was administered i.v. on Day 1. The dose was individualized using the Calvert formula (the target dose was AUC = 5). VP-16 was administered orally at the dose of 50 mg/m2 Days 1-14, HMM at the dose of 150 mg/m2 po Days 14-28. Therapy was repeated every 28 days for a total of 6 courses. In order to avoid severe leukopenia and delays in the treatment administration, G-CSF 5 micrograms/kg/day sc Days 8-14 (or until postnadir recovery of neutrophil count > 10,000/mm3) and Days 22-28 was administered. All patients were evaluable for toxicity. No treatment-related deaths occurred. Myelotoxicity was the main side effect. It was grade 3-4 in a total of 13/29(45%) patients. One patient discontinued treatment after the first course due to HMM-related gastrointestinal toxicity. The actual delivered dose intensity was 89% of the planned dose. At the time of this analysis (April 1994) 26 patients are evaluable for response. Fifteen patients achieved a clinical complete remission and 9 a partial response for a 92% overall response rate. Fourteen patients accepted second-look laparotomy. We observed 11 pathological complete regressions (42%; 95% CI, 21-63). At a median follow-up of 16 months 3 deaths have occurred. Only 2 patients with NED at second-look laparotomy have relapsed. We stopped the accrual since the 95% confidence interval of the pCR-rate observed exceeded 20%. This new first-line regimen seems to be highly effective in patients with poor-prognosis advanced ovarian cancer, although the data are not yet sufficiently mature for a final analysis of time to progression and overall survival.
