RESUMEN
BACKGROUND: A randomized, controlled study was performed to compare vaginoscopic versus traditional (speculum with or without tenaculum) hysteroscopy in terms of pain score and procedure time. METHODS: Three hundred patients were randomized in two groups: Group A, diagnostic hysteroscopy with vaginoscopic approach (150 patients) and Group B, diagnostic hysteroscopy with traditional approach (150 patients). All procedures were performed using a semi-rigid 3.5-mm minihysteroscope with a 0 degrees grade optic. Patients of each group were divided into three subgroups according to their reproductive status: fertile nulliparous (FN), fertile multiparous (FM) and post-menopausal (MEN) women. Women were asked to rate their degree of pain during four phases of the procedure: introduction of hysteroscope (Group A) or speculum (Group B) into the vagina (Phase I) and progression through cervical canal up to internal uterine orifice (IUO) (Phase II), inspection of uterine cavity (Phase III) and performing of endometrial biopsy (Phase IV). A total pain score was calculated for each group. For each patient, the duration of hysteroscopy was recorded from the introduction to the extraction of the scope (Group A) or of the speculum (Group B). RESULTS: Although the median total pain scores were 2 in each group, the 95% confidence interval for vaginoscopic hysteroscopy (1.86-2.01) was significantly (P < 0.05) lower than that for traditional hysteroscopy (2.10-2.26). Comparison between the corresponding phases of the procedure showed the only significant difference during Phase I of the procedure [Group A: 1 (95% CI 1.0-1.18) versus Group B: 2 (95% CI 2.3-2.8); P < 0.05]. No significant differences in terms of duration of the procedure were observed between the two approaches. CONCLUSIONS: When surgeons using vaginoscopic hysteroscopy with a semi-rigid minihysteroscope were compared with those using traditional approach and the same instrumentation, the operating times and the patients' pain scores were similar.

Hysteroscopy could be an interesting approach to evaluate the cervical invasion by endometrial cancer. From 2003 to 2004 we performed 30 hysteroscopy with endometrial biopsy with conclusive diagnosis of endometrial carcinoma and we calculated the sensitivity and specificity of hysteroscopy in assessing tumor invasion of the uterine cervix. Our data showed an high sensitivity and specificity of hysteroscopy that reported almost the same value of the histological examination. Our conclusions are that hysteroscopy is a suitable examination in endometrial cancer staging.

OBJECTIVE: To evaluate satisfaction rate, efficacy and complication rate of carbon dioxide (CO2) vs normal saline as uterine distension medium for outpatient diagnostic hysteroscopy in patients with suspicious endometrial cancer. METHODS: Thirty-eight undergoing outpatient hysteroscopy performed with carbon dioxide (group A) or normal saline (group B). Quality of vision of uterine cavity, procedure time, complications, patient discomfort, satisfaction rate have been evaluated. RESULTS: In group B a significant reduction in abdominal pain, shoulder tip pain and a lower incidence of vasovagal reactions were observed in comparison to group A. In normal saline group we found a higher satisfaction rate and a lower operative time in comparison to the CO2 group. CONCLUSIONS: Uterine distension with normal saline seems to have less adverse effects and is better accepted by patients.

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.

In this prospective, controlled, randomized study, we compared the effect of a low-dose 21-day combined oral contraceptive (COC) containing 20 microg ethinyl estradiol (EE) and 75 microg gestodene (GTD) (Group A; n = 19) with an ultra-low-dose 24-day COC containing 15 microg EE and 60 microg GTD (Group B; n = 18) on bone turnover and bone mineral density (BMD) in young, fertile women. Nineteen healthy fertile women were used as untreated controls (Group C). At 3, 6, 9 and 12 months of the study serum osteocalcin (BGP), urinary pyridinoline (PYD) and deoxypyridinoline (D-PYD) were measured in all subjects. At baseline and after 12 months BMD was determined at lumbar spine by dual-energy X-ray absorptiometry in all patients. In both Groups A and B, urinary levels of PYD and D-PYD at 6, 9 and 12 months, were significantly reduced in comparison with basal values and with control subjects (p < 0.05). No significant differences in urinary PYD and D-PYD levels were observed between Groups A and B during the entire period of treatment. At 12 months, no statistically significant difference in spinal BMD values was detected between the three groups and in comparison with basal values. The present study suggests that the two COCs could exert a similar positive effect on bone turnover in young postadolescent women, without any significant and appreciable modification of BMD.

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.

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.

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.

BACKGROUND: To assess the effect of estriol treatment per vaginam before Burch culposuspension in postmenopausal women with stress urinary incontinence (IUS). DESIGN: prospective randomised study. SETTING: Department of Gynaecology, Obstetrics and Physiopathology of Human Reproduction-Medical School-University of Naples Federico II . PATIENTS: twenty women in postmenopause at least from five years with a urogenital symptomatology due to IUS. INTERVENTIONS: women were randomised into one of two groups (treated or control) and they were submitted to an evaluation of vulva and vagina trophism. All the women were submitted to a urodynamic examination and to a transvaginal ultrasonography with evaluation of pubis-bladder neck distance, bladder and proximal urethra position, before treatment, one week before the operation and after six months from the same operation. EVALUATIONS: subjective symptomatology and urodynamic parameters between treated and control groups before and after operation. RESULTS: After 12 weeks of treatment, a significant improvement of subjective symptomatology and a not significant improvement of all the urodynamic parameters in the treated group in comparison with the control group have been demonstrated, while any anatomic alteration compared with the basal hasn t been observed. After six months from the operation in all the women a significant reduction of subjective quantity of urine lost after a strain has been demonstrated and significant variations of urodynamic parameters without significant differences between treated group and control group were also observed. CONCLUSIONS: The estriol treatment per vaginam is not so effective on the result of Burch culposuspension in postmenopausal women with IUS.
