[Diagnosis of fertility with a personal hormonal evaluation test].

BACKGROUND: To evaluate the efficacy of the urinary test "Persona" in the recognition of the fertile period comparing hormonal assay and monitoring the follicular growth by ultrasonography. METHODS: Twenty women have used "Persona" for 13 cycles (200 cycles). This device evaluates changes in E-3-G and LH concentrations and estimates the fertile days which are displayed by a red light. Inclusion criteria were: age 22-45, regular menstrual cycles (23-35 days), absence of the polycystic ovary syndrome. The participants underwent vaginal ultrasonography in several days (one of the first 7 "green days", the first "red day", the ovulation day "O", and the first "green day" after ovulation) and determination of blood concentration of LH, in the ovulation day, and progesterone, in the 21st day of cycle. RESULTS: Vaginal ultrasonography was in agreement with predictions of "Persona" in 96% in the first "green days", in 94% in the first "red day", in 95,8% in the ovulation day and in 97,5% in the first "green day" after ovulation. All participants with ultrasonographic evidence of ovulation had a concentration of LH included in 13-71 mUI/ml range and of progesterone included in 12-50 ng/ml range. CONCLUSIONS: These results suggest that the "Persona" test is effective in the recognition of the fertile period, but a correct maintenance of the microcomputer is important for the best reliability of method. The method seems to be a wellcome alternative for couples who want to use natural family planning.

Vanadate regulates the insulin mitogenic effect by modulating SHP-2 association with insulin receptor substrate 1 in JAr human choriocarcinoma cells.

Maternal hyperglycemia alters placental glucose metabolism and induces placental hypercellularity. In this study we investigated, in JAr cells, the effect of a protein tyrosine phosphatase inhibitor, vanadate, on the insulin receptor substrate 1 (IRS1)-mitogen-activated protein kinase (MAPK) pathway and on cell proliferation in the presence of normal or high glucose concentration. When JAr cells were cultured in the presence of 25 mmol/l glucose, treatment with vanadate completely prevented SHP-2 association with IRS1. However, vanadate treatment reverted the effect of high glucose on basal and insulin-stimulated insulin receptor and IRS1 phosphorylation. Similar effects were observed on MAPK activation. These events determined a related modification in cell proliferation. Indeed, after high glucose and vanadate treatment, thymidine incorporation levels were comparable to those observed in the presence of normal glucose concentration and in the absence of vanadate. Therefore, in JAr cells, vanadate exerts an inhibitory effect on cell proliferation. This action is related to a modulation of the SHP-2 association with IRS1 that in turn might regulate the phosphorylation state of the main substrates involved in mitogenesic signaling of the insulin receptor.

[Hormone therapies in pregnancy].

Maternal endocrine disorders can have detrimental effects on the fetus and the pregnancy can affect the course of a pre-exisiting endocrinopathy or induce the onset of one of these disorders. Therapies for endocrine disorders are not always safe to administer during pregnancy. Before administering any therapy to the mother, the effects on the fetus, the degree of placental trespassing as well as the potential damaging effects must be assessed. An accurate evaluation of the risks/benefits of any drug to be used on the mother is needed, assessing above all a potential theratogenic effect. In this review, the incidence of the main endocrine disorders, their evolution during pregnancy, their effects on mothers and fetuses and new acquisition on the treatment during pregnancy are discussed.

[Options for uterine distension during hysteroscopy].

BACKGROUND: This comparative study evaluated effectiveness, complications and patient satisfaction following the use of carbon dioxide (CO2) compared with physiological solution for uterine distension during hysteroscopy. The study was motivated by doubts concerning the choice of distension methods and the implications of their use. METHODS: The study population included 189 patients attending the outpatient services of the Obstetrics/Gynecological Clinic of the University of Naples for sterility/infertility disorders. Patients were randomly assigned by computer to either of two treatment groups. Both groups underwent hysteroscopy. In Group A (92 patients), uterine distension was performed using carbon dioxide (CO2), while in Group B (97 patients) physiological solution was used. Treatment was assessed for effectiveness, causes of discomfort, patient compliance and satisfaction rate. RESULTS: Compared with carbon dioxide (CO2), the use of physiological solution as a means of uterine distension was demonstrated certain advantages that were statistically significantly for the parameters of operating time, onset of vagal reactions, causes of discomfort, compliance and satisfaction rate, and cost-effectiveness of equipment. CONCLUSIONS: The use of physiological solution for uterine distension was observed to enhance patient compliance with hysteroscopy, because the method was better tolerated, more rapid and involved fewer failures.

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.

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.

[Changes of leptin levels in menopause].

One of the main advances in the field of metabolic control of body weight and obesity treatment was the identification of the OB protein or leptin, that plays an important role in controlling body weight, signalling to the CNS the amount of body fat. Indeed, leptin levels are positively correlated to indices of body fat, namely total fat mass, percent body fat and body mass index (BMI). This protein may be also the signal that indicates the nutritional status to the reproductive axis. Whether this signal is exerted directly on the gonads or through the neuroendocrine axis is still to be determined. A sexual dimorphism between male and female in serum leptin levels has been observed, with the latter showing higher serum leptin levels. This evidence has led to the hypothesis that estrogens might have a stimulatory role in leptin secretion. To evaluate this hypothesis, several authors have determined serum leptin levels in postmenopausal women that have estrogen levels comparable to those present in men. The results of these studies are contradictory and the aim of this article has been the revision of data present in the literature regarding serum leptin levels in menopause and to correlate them to body composition changes taking place during menopause.

[Effects of gonadotropins on oocyte maturation].

The use of exogenous gonadotropins, alone or in association with other drugs, is a useful tool in the treatment of anovulation. The first stages of the follicologenesis are gonadotropin independent up to the preantral stage. The final phase of this process begins when follicles grow faster during the luteal phase of the preceding cycle, the so-called gonadotropin-dependent phase. Recent studies confirmed the central role of FSH in follicular and oocyte maturation, but also re-evaluated the actions of LH, in particular during the first phases of these processes. LH induces the physiological development of the follicle, acting only on a limited number of follicles, while FSH protects against atresia. In the absence of FSH the development will be delayed. It seems obvious that both hormones are necessary, that a stimulation protocol may rely only on FSH, but the addition of LH will render it more physiological.

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.

The importance of user compliance on the effectiveness of natural family planning programs.

Nowadays, there is an increasing interest in natural family planning methods. The biological basis for the application of natural family planning methods is the recognition of ovulation and, more extensively, of the fertile period. Several studies in the past decade have shown the efficacy of these methods and that the main cause of failure was either a conscious departure from the rules of the method or erroneous application of the method. Another problem affecting natural family planning that has been highlighted is the relatively high discontinuation rate. These features are probably due to low compliance in applying the natural family planning rules, which may be too demanding for a number of couples. In this review, there are comments on the application of natural family planning methods, the discontinuation rates and the failure of the method due to mistakes in the studies carried out in the past 15 years. Steps that can be taken to limit mistakes and discontinuity are also addressed.

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.

Efficacy of methods for determining ovulation in a natural family planning program.

OBJECTIVE: To evaluate the efficacy in ovulation detection of methods used in natural family planning in comparison with pelvic ultrasonography. DESIGN: Prospective analysis of ovulation detection by natural family planning methods and ultrasonography. SETTING: Natural family planning clinic, Department of Obstetrics and Gynecology, University of Naples "Federico II". PATIENT(S): Forty healthy women who were highly motivated to use natural family planning. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Transvaginal ultrasonographic findings, urinary LH levels, salivary beta-glucuronidase activity, salivary ferning levels and characteristics of cervical mucus, and BBT. RESULT(S): Urinary LH level determination yielded a 100% correlation with the simultaneous ultrasonographic diagnosis of ovulation. Mucus sensations and characteristics yielded a 48.3% correlation when simultaneously evaluated with ovulation. Beta-glucuronidase levels yielded a 27.7% correlation. The salivary ferning test had a 36.8% ovulation-detection rate the day of ovulation, but 58.7% of results were uninterpretable. Body temperature measurements yielded a 30.4% correlation with the simultaneous ultrasonographic diagnosis of ovulation. CONCLUSION(S): Measuring urinary LH levels is an excellent method for determining ovulation. Although variations in mucus characteristics and basal body temperature correlate somewhat with ovulation, the length of the fertile period is overestimated with these methods. The salivary ferning test and measurement of beta-glucuronidase levels are not good methods for home ovulation testing.

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.
