GH release after GHRH plus arginine administration in obese and overweight women with polycystic ovary syndrome.

Few and unclear data are available in the literature about the relationship between impairment of GH/IGF-I axis and polycystic ovary syndrome (PCOS). This study was aimed to evaluate the basal GH and IGF- levels, and GH release after challenge test in obese and overweight women with PCOS. Thirty patients with PCOS and other 30 healthy women matched for age, body mass index (BMI) and waist-hip ratio (WHR) were studied. Serum follicle-stimulating hormone (FSH), LH, PRL, E2, P, 17OH-progesterone (17OH-P), total T, delta4, DHEA-S, SHBG, GH and IGF-I levels were evaluated in each subject. A GHRH plus arginine challenge test was performed in all subjects. After provocative test, in PCOS and control women the GH levels were significantly (p<0.05) higher in comparison to basal values from 30 min to 120 min. At the same times, a significant (p<0.05) difference was observed between women with PCOS in comparison to healthy women. The mean peak value of GH resulted significantly (p<0.05) lower in PCOS women in comparison to healthy women. The total GH response (area under curve, AUC) to GHRH plus arginine test resulted significantly (p<0.05) lower in PCOS than in healthy women. These findings were statistically significant (p<0.05) also considering the distinction in obese and overweight women. The AUC for GH secretion was significantly lower (p<0.05) in obese in comparison to overweight subjects in the control group, whereas no significant difference was detected between obese and overweight women in the PCOS group. In conclusion, in PCOS women there is a BMI-independent alteration of the GH levels. Further investigations will be necessary to establish the real cause of these data.

[Genetic mutations, acquired coagulation system disorders and obstetric pathology. Personal experience].

BACKGROUND: To evaluate the incidence of thrombophilic disorders such as Factor II mutation, Leiden factor V and MTHFR genotype, and anti-phospholipid anti-bodies syndrome in women with or without pregnancy related problems. METHODS: Sixty-three patients (group A) with pregnancy complications were included in the study and tested for Factor V mutation, Factor II mutation, 5-10 MTHFR reductase mutation and anti-phospholipid antibodies syndrome. The incidence of disorders was compared with thirty-six pregnancies without complications (control study, group B). RESULTS: Hemostasis thrombophilic like disorders, were significantly high (p=0.001 vs group B). Nobody in both groups was homozygous for Leiden mutation or prothrombin mutation (Factor II). The prevalence of Factor V mutation in heterozygosis was significantly (p=0.01) higher in group A in comparison with group B. The MTHFR mutation in homozygosis was found in 21.4% of group A while in the control group it was 11%. Factor II mutation in heterozygosis and anti-phospholipid antibodies were found only in group A. CONCLUSIONS: It is important to evaluate the hemocoagulation patterns in women with a history of complicated pregnancies.

Comparison between two laparoscopic retropubic urethropexy.

BACKGROUND: To compare two different transperitoneal laparoscopic urethropexy procedures. METHODS: In this prospective randomized open trial, 60 women affected by genuine stress incontinence were enrolled and randomized in two groups of surgical technique. Group A was treated with transperitoneal laparoscopic retropubic urethropexy using non absorbable sutures, and group B with prolene meshes fixed with tackers or staplers. The failure rate was defined subjectively and objectively. The subjective evaluation was performed asking the patients if they had urine loss and expressing the symptomatology using a visual analog scale before surgery and after each follow-up visit. The objective evaluation was performed with clinical evaluation and/or with the use of multichannel urodynamic studies. RESULTS: No significant differences in intra- operative and postoperative complications between the two groups were observed. The subjective failure rate was not significantly different between the two groups at 3, 6, and 12 months from surgery. At 3 and 6 months follow-up, the objective failure rate was not significantly different between the two groups. Moreover, at 12 months from surgical procedure the objective failure rate was significantly lower in group A than in group B. CONCLUSIONS: Transperitoneal laparoscopic retropubic urethropexy performed using sutures is more effective than the mesh technique.

Effectiveness of short-term administration of tibolone plus gonadotropin-releasing hormone analogue on the surgical outcome of laparoscopic myomectomy.

OBJECTIVE: To evaluate whether administration of tibolone changes the effectiveness of GnRH analogue administered before laparoscopic myomectomy. DESIGN: Prospective, randomized, open, placebo-controlled clinical trial. SETTING: Department of Gynecology and Obstetrics, University of Naples Federico II, Naples, Italy. PATIENT(S): 66 women with symptomatic uterine leiomyomas. INTERVENTION(S): Treatment for 2 months with leuprolide acetate and iron tablets, plus tibolone (group A) or placebo tablets (group B); or with leuprolide acetate and iron tablets (group C). MAIN OUTCOME MEASURE(S): Laparoscopic myomectomy at the end of treatment. Operative time and blood loss during surgery were recorded. Uterine volume, volume and number of uterine leiomyomas, volume and echogenicity of the largest uterine leiomyomas, hematologic data, and myoma-related symptoms were evaluated at baseline and 1 week before and after surgery. RESULT(S): Uterine and leiomyomata volume and myoma-related symptoms were significantly reduced and hematologic variables improved significantly in groups A and B, compared with baseline values and with group C. Operative time and blood loss were significantly less in groups A and B than in group C. After surgery, hematologic variables were significantly worse in group C compared with groups A and B. During the study no significant difference was detected between groups A and B. CONCLUSIONS: Administration of tibolone administration in patients treated with GnRH analogue before laparoscopic myomectomy does not change the effectiveness of the analogue administered alone.

Effects of raloxifene treatment on uterine leiomyomas in postmenopausal women.

OBJECTIVE: To evaluate the effects of raloxifene administration on uterine and uterine leiomyoma sizes in postmenopausal women. DESIGN: Prospective randomized, double-blind, placebo-controlled clinical trial. SETTING: Department of Gynecology, Obstetrics, and Pathophysiology of Human Reproduction, University of Naples "Federico II", Italy. PATIENT(S): Seventy spontaneous postmenopausal women affected by uterine leiomyomas. INTERVENTION(S): Twelve cycles (of 28 days each) of treatment with raloxifene (60 mg daily per os) or placebo. MAIN OUTCOME MEASURE(S): At entry and at every 3 cycles, uterine and uterine leiomyoma dimensions were measured by means of transvaginal ultrasound. The difference between uterine and leiomyoma volumes (Delta size) was calculated in all subjects. The characteristics of uterine bleeding and the side effects of the treatments were assessed using a daily diary. RESULT(S): After 6, 9, and 12 cycles of therapy, in subjects treated with raloxifene, the mean uterine and uterine leiomyoma size were significantly decreased, and the mean Delta size significantly increased in comparison with basal values and the placebo group. No significant differences in uterine bleeding were detected between the two groups. CONCLUSION(S): In postmenopausal women raloxifene appears to act selectively on uterine leiomyomas, reducing their size.

Laparoscopic Burch colposuspension: a randomized controlled trial comparing two transperitoneal surgical techniques.

OBJECTIVE: To compare the effectiveness of two transperitoneal laparoscopic Burch procedures. METHODS: The sample size required was 30 subjects per group to detect a statistically significant estimated difference of 15% between two surgical procedures with an alpha = 0.05 and a power of 0.7. Sixty women affected by genuine stress incontinence (GSI) were enrolled and randomly assigned to two groups of 30 women each. All women were treated with the transperitoneal laparoscopic Burch procedure using nonabsorbable sutures (group A) or Prolene mesh (Ethicon, Somerville, NJ) fixed with tacks or staples (group B). The failure rate was defined subjectively and objectively. The subjective evaluation was performed by asking the women to rate their urine loss on a visual analog scale. The objective evaluation was a clinical evaluation using multichannel urodynamic studies. RESULTS: The subjective failure rate was not significantly different between the two groups at 3 months (0% for both groups), 6 months (3.7% versus 3.8% for groups A and B, respectively), and 12 months (7.4% versus 15.4% for groups A and B, respectively) after surgery. At 3 months (3.7% versus 3.8% for groups A and B, respectively) and 6 months (7.4% versus 15.4% for groups A and B, respectively) follow-up, the objective failure rate was not significantly different between the two groups. However, at 12 months after the surgical procedure, the objective failure rate was significantly lower in group A than in group B (11.1% versus 26.9%, respectively; P <.05). CONCLUSION: Transperitoneal laparoscopic Burch colposuspension performed using sutures was more effective than the mesh technique.

Transdermal hormone replacement therapy in postmenopausal women with uterine leiomyomas.

OBJECTIVE: To evaluate the effects of transdermal hormone replacement therapy (HRT) on uterine and leiomyoma size and on uterine bleeding patterns in postmenopausal women with uterine leiomyomas. METHODS: The required sample size was calculated to be 30 subjects per group to detect an effect on the size of one standard deviation (SD) with an alpha value of 0.05 (two-sided) and a power 1 - delta = 0.8. At the end of the study, the power analysis showed a value of beta = 0.826. Seventy postmenopausal women with uterine leiomyomas were enrolled and treated for 12 cycles of 28 days each with transdermal 17 beta-estradiol (E(2)) patches plus oral medroxyprogesterone acetate continuously added (group A) or with calcium carbonate (group B). At entry and every three cycles, uterine and leiomyoma dimensions were measured by transvaginal ultrasonography. To evaluate the effect of transdermal HRT on the characteristics of uterine bleeding, 35 healthy postmenopausal women without uterine leiomyomas (group C) were enrolled and treated with the same regimen as group A. A daily diary was used to record the abnormal uterine bleeding episodes, and a rank scale was used to assess the severity of bleeding. RESULTS: There were no significant changes in mean uterine or leiomyoma size between groups A and B, or in each group compared with basal values. No significant difference was detected between groups A and C in uterine bleeding patterns. CONCLUSION: Transdermal HRT did not increase the size of uterine leiomyomas or affect uterine bleeding patterns in postmenopausal women.

Conscious sedation versus general anaesthesia for minilaparoscopic gamete intra-Fallopian transfer: a prospective randomized study.

BACKGROUND: Gamete intra-Fallopian transfer (GIFT) is a successful technique for infertile women, and is performed almost exclusively by laparoscopy under general anaesthesia. METHODS: We performed a prospective randomized study of 67 infertile patients to assess the efficacy of minilaparoscopic GIFT under conscious sedation/local anaesthesia (group A) compared with general anaesthesia (group B). Operative and discharge times and pregnancy outcome were evaluated in both groups. RESULTS: Operative time was similar in both groups. The rate of patients discharged 2 h after surgery was significantly higher in group A. The necessity for postoperative analgesics was significantly higher in group B. No significant differences were noted between the two study groups in terms of pregnancy outcome. CONCLUSIONS: Conscious sedation and local anaesthesia will allow us to perform an outpatient minilaparoscopic GIFT without the need for general anaesthesia. The simplicity of the method, and the quicker discharge time in comparison with general anaesthesia, offer a detectable benefit for patients.

[Prenatal diagnosis of beta-thalassemia. A study based in Calabria].

BACKGROUND: The aim of this study was to underline, given the well-known incidence of beta thalassemia in Calabria, the possibility of establishing a prevention programme based on an increased awareness among the population using information and health education, genetic consultancy to identify high-risk subjects and prenatal diagnosis. METHODS: Between January 1992 and December 1999, we analysed 181 high-risk couples for beta thalassemia using chorionic villi sampling (CVS) performed with an echoguided transcervical or transabdominal route. A steady rise was observed over the years in the number of couples asking for prenatal diagnosis, thus demonstrating that patients and doctors are increasingly aware of the importance of a correct prenatal diagnosis. The variability of molecular defects found and the number of complications linked to the technique used are underlined. RESULTS: Prenatal diagnosis revealed 46 fetuses with the disease (24.8%), 97 heterozygotes (53.2%) and 41 healthy fetuses (22%). Only one malformation was observed in the 41 healthy fetuses. The authors also report the incidence of complications linked to CVS. In overall terms, 2.2% of pregnancies ended in spontaneous abortions (4 cases) and 2.75% with preterm births (5 cases). These complications could not be correlated with gestational age at the time of biopsy or the number of attempts made to obtain an appropriate sample.

Minilaparoscopic ovarian drilling under local anesthesia in patients with polycystic ovary syndrome.

OBJECTIVE: To assess pain control in patients with polycystic ovary syndrome (PCOS) who are undergoing ovarian drilling during minilaparoscopy under local anesthesia and conscious sedation and to evaluate the efficacy of this protocol compared with the traditional approach in terms of operative and discharge times, subsequent ovulation, and pregnancy. DESIGN: Prospective randomized study. SETTING: University hospitals and private day-surgery unit. PATIENT(S): Sixty-two infertile women with PCOS. INTERVENTION(S): Group A underwent minilaparoscopic ovarian drilling under local anesthesia and conscious sedation. Group B (control group) was treated with traditional ovarian drilling by laparoscopy under general anesthesia. MAIN OUTCOME MEASURE(S): Intraoperative pain score in group A. Hormonal profile before and after surgery, operative and discharge times, postoperative analgesic requirements, and reproductive follow-up in both groups. RESULT(S): Group A showed a good intraoperative pain score. The hormonal profile after surgery did not differ between groups A and B. Operative times were also similar for both groups. The number of patients discharged within 2 hours after surgery was significantly higher in group A. The need for postoperative analgesics was significantly higher in group B. No statistically significant differences were noted between the groups in terms of pregnancy and ovulation rates. CONCLUSION(S): Intraoperative and postoperative local anesthesia plus conscious sedation allows outpatient bilateral ovarian drilling by minilaparoscopy to be performed without general anesthesia. The high pregnancy rates, the simplicity of the method, and the faster discharge time offer a new option for patients with PCOS who are resistant to clomiphene citrate. Moreover, ovarian cauterization can be performed simultaneously with a diagnostic minilaparoscopy and integrated into the infertility workup of these patients.

Is local anesthesia an affordable alternative to general anesthesia for minilaparoscopy?

STUDY OBJECTIVE: To determine if minilaparoscopy under local anesthesia is at least as reliable and affordable as that performed under general anesthesia. DESIGN: Prospective, randomized study (Canadian Task Force classification I). SETTING: University-affiliated hospital. PATIENTS: One hundred sixty-four consecutive women evaluated for infertility. INTERVENTION: Diagnostic minilaparoscopy performed after women were randomized to receive general or local anesthesia with conscious sedation. MEASUREMENTS AND MAIN RESULTS: Levels of postoperative pain measured by visual analog scale; volume of CO(2) used; length of procedure, complete pelvic evaluation, and hospitalization; complications; and pathologic diagnosis were evaluated. The groups were comparable in age, years of infertility, and symptoms. For women receiving local anesthesia, 5.5% required general anesthesia to complete the procedure. Women in both groups required postoperative analgesics. The groups had no statistically significant differences in pain level 1 hour after the procedure, number of complications, and pelvic pathology. Patients who had local anesthesia required a smaller volume of CO(2) (p <0.01) and their hospitalization was significantly shorter (p <0.01). However, in 15% of these women pelvic visualization was incomplete, compared with 7.2% in the general anesthesia group. CONCLUSION: Minilaparoscopy performed under local anesthesia was as reliable and affordable as when performed under general anesthesia.

Minilaparoscopic ovarian biopsy performed under conscious sedation in women with premature ovarian failure.

OBJECTIVE: To evaluate the feasibility of a bilateral multiple ovarian biopsy through minilaparoscopy under local anesthesia and conscious sedation and to assess the efficacy of this technique as compared to the traditional laparoscopic approach. STUDY DESIGN: Twenty-five infertile women with premature ovarian failure underwent bilateral ovarian biopsy plus chromoperturbation. Twelve patients were treated with minilaparoscopy (minilap group) and preoperatively received mepivacaine for subcutaneous local anesthesia and midazolam plus fentanyl for conscious sedation. Following minilaparoscopy, 40 mL of 0.5% intraperitoneal subdiaphragmatic lidocaine and 5 mL of ropivacaine, 7.5 mg/mL, for infiltration of the trocar insertion sites were administered. Thirteen women (control group) were treated with the traditional laparoscopic approach under general anesthesia. If necessary, ketoprofene or intramuscular ketorolac was administered following surgery. Postoperative pain score was evaluated by a 1-10 visual analogic scale immediately after surgery and in the following 24 hours; in addition, the quantity of ovarian biopsy material for the pathologist and the discharge and operative times were evaluated. RESULTS: The minilap group had lower postoperative pain scores postoperatively. Operative time was similar in both groups. The rate of discharge two hours after surgery was significantly higher in the minilap group. In all cases the amount of ovarian tissue was sufficient for diagnosis. Twenty-one patients were affected by premature menopause and four by resistant ovary syndrome. The need for postoperative analgesics was significantly higher in the control group. CONCLUSION: Minilap allows the performance of bilateral, multiple ovarian biopsy under local anesthesia and conscious sedation in association with chromoperturbation and the obtaining a sufficient amount of ovarian tissue for histopathologic diagnosis. Intraperitoneal lidocaine administration and ropivacaine infiltration of the trocar sites were beneficial for patients undergoing operative minilap in a day-surgery setting. The effect of these drugs was obviously temporary; however, low postoperative pain scores and low additional analgesic requirement permitted early discharge, within two hours after surgery.

[Pregnancy management in women with thalassemia].

Thanks to the improvement of the techniques of assisted fecundation, of the obstetric management and of the fetal and neonatal monitoring now it's possible for a woman suffering from beta-thalassemia to have a child. Our purpose is to stress the importance to control the high maternal and fetal risk through the monitoring of several scales. The problems, connected with pregnancy of beta-thalassemic women are discussed, emphasizing the connection between pregnancy management and gestational and neonatal outcome. A variety of problems should be considered such as the informed consent about maternal and fetal risks, the problems caused by infectious agents or due to the use of some antiviral; the difficulties connected with heart and endocrine diseases are also discussed. Personal experience, from 1995 to 1999, on 4 beta-thalassemic pregnant women (three with the intermediate type and one with the major type) is reported.

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.
