RESUMO

Purpose: The Italian Society of Contraception identified as one of its priorities the need to give recommendations on management of contraception during Coronavirus-Covid 19 pandemiaMaterials and methods: A concise communication was produced which summarises in an easy-to-read format suitable for clinicians the management of the different contraceptives mostly used. Information how to manage contraception in different conditions is presented.Results: Women may, in general, continue to use either intrauterine and or hormonal contraceptives. The use of condom should be added to any hormonal contraceptive, when the contraceptive efficacy is reduced or when women stop the contraceptive method.Conclusion: At the present time, during the Coronavirus-Covid 19 pandemia, no data contraindicate the use of intrauterine or hormonal contraceptives. Conversely the use of an appropriate contraception is advocate to prevent unintended pregnancies.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the use of ultrasound (US) soft markers as a first-line imaging tool to raise suspicion of rectosigmoid (RS) involvement in women suspected of having deep endometriosis. METHODS: We included in this prospective observational study all patients with clinical suspicion of deep endometriosis who underwent diagnostic transvaginal US evaluation at our unit from January 2016 to February 2017. Several US soft markers were evaluated for prediction of RS involvement (presence of US signs of uterine adenomyosis, presence of an endometrioma, adhesion of the ovary to the uterus (reduced ovarian mobility), presence of 'kissing ovaries' (KO) and absence of the 'sliding sign'), using as the gold standard expert US examination for the presence of RS endometriosis. RESULTS: Included were 333 patients with clinical suspicion of deep endometriosis. Of these, 106 had an US diagnosis of RS endometriosis by an expert. The only significant variables found in the prediction model were absence of the sliding sign (odds ratio (OR), 13.95; 95% CI, 7.7-25.3), presence of KO (OR, 22.5; 95% CI, 4.1-124.0) and the interaction between these two variables (OR, 0.03; 95% CI, 0.004-0.28). Regarding their interaction, RS endometriosis was present when KO was absent and the sliding sign was present in 10% (19/190) of cases, when both KO and the sliding sign were present in 71.4% (5/7) of cases, when both KO and the sliding sign were absent in 60.8% (76/125) of cases and when KO was present and the sliding sign was absent in 54.5% (6/11) of cases. Thus, when the sliding sign was absent and/or KO was present, transvaginal US showed a specificity of 75% (95% CI, 69-80%) and a sensitivity of 82% (95% CI, 73-88%). CONCLUSIONS: US findings of absence of the sliding sign and/or presence of KO in patients with clinical suspicion of endometriosis should raise suspicion of RS involvement and indicate referral for expert US examination, with a low rate of false-negative diagnosis.

RESUMO

The authors reply to the comment by R. P. Steer discussing the reasons for their incorrect assignment of the luminescence decay of the novel compound 5,10,15-(triphenyl),20-[ethynyl-(4-carboxy)phenyl]tetrabenzoporphyrinate Zn(ii) (PETBP). Further DFT and TDDFT calculations have been performed on the compound to investigate the possibility of a direct S2-S0 decay instead of a S2-S1 conversion with a subsequent emission to the ground state. In addition, the presence of traces of very luminescent contaminants of the ring-opened type has been considered on the grounds of calculated absorption and fluorescence spectra. The results of these investigations confirm that the S2-S0 emission reported in the commented paper is not attributable to the target molecule but rather to a neglected luminescent impurity.

RESUMO

OBJECTIVES: To evaluate efficacy, tolerability and safety of Monurelle Biogel® vaginal gel for treatment of vaginal dryness. METHODS: Multicenter, national, randomized, controlled vs. no-treatment, open-label study. Ninety-five postmenopausal women were randomized (48 to Monurelle Biogel® and 47 to no treatment). Primary endpoint was the change of Verbal Rating Scale (VRS) total score of vaginal atrophy (VA) symptoms after 8-week treatment. The main secondary endpoints were VRS single-item score, Vaginal Health Index (VHI) score, Maturation Index (MI), Female Sexual Function Index (FSFI), and Female Sexual Distress Scale-Revised (FSDS-R). RESULTS: The VRS total score was statistically significant in favor of the treatment group on day 28 (p = 0.001) but not on day 56 (p = 0.064). By excluding women who were not sexually active, the total VRS scores reached the criteria for clinical success in 27/43 subjects (62.8%) in the control arm and in 38/46 subjects (82.6%) in the treatment arm (p = 0.035) on day 56. The VHI score significantly changed in the active arm (4.71 ± 4.85 vs. 0.28 ± 1.71) (p < 0.001) on day 56. Even the MI significantly improved, with an increase in the percentage of superficial cells (p = 0.01). The improvements in both VHI and MI were still present at the follow-up visit after the discontinuation of the treatment (day 84). Sexual function and distress showed a statistical significant difference on day 56. CONCLUSIONS: Monurelle Biogel® vaginal gel applied twice daily for 8 weeks is effective in relieving vaginal dryness and other VA symptoms. Such a clinical meaningful effect persists at least 4 weeks and is supported by an improvement in the vaginal environment. Trial Registration clinicaltrials.gov Identifier: NCT02994342.

RESUMO

PURPOSE OF INVESTIGATION: To evaluate the effect of soy isoflavones and inulin (SII) on hot flushes (HF) and quality of life in a clinical setting, the authors conducted an observational study. MATERIALS AND METHODS: The authors performed an observational, prospective, multicentric study on women in peri-/post-menopause treated or untreated with a product present on the Italian market, consisting in a mixture of calcium (500 mg), vitamin D3 (300 IU), inulin (3 g) and soy isoflavones (40 mg). RESULTS: A total of 135 patients, 75 (55.6%) in the SII group and 60 (44.4%) in the untreated group entered the study. After three months, the mean number of HF declined of 2.8 (SD 3.7) in the SII group and 0.0 in the untreated one. The corresponding values after six months were -3.7 (SD 2.7) in the SII group and -0.9 (SD 5.3) in the control group (p = 0.02). CONCLUSION: This observational trial suggests a possible beneficial effect of a dietary soy supplement containing 40 mg of isoflavone/day plus inulin in the management of menopausal symptoms such as hot flashes.

RESUMO

AIM: evaluate the efficacy of an estroprogestin EP containing 20 mcg ethinilestradiol (EE) and 3 mg drospirenone (DRSP) in the treatment of hyperandrogenism. METHODS: In this study, twenty hyperandrogenic patients were treated with an EP containing EE 20 mcg and DRSP 3 mg in 24+4 regimen for three months. Skin evaluation was performed both quantitatively and qualitatively. RESULTS AND CONCLUSION: This EP combination showed, after a short-term treatment (three months) to decrease significantly seborrhea, acne, and circulating androgens (testosterone, deidroepiandrosterone sulphate, and androstenedione), while increased sex hormone binding globulin levels. Moreover, this EE 20 mcg/DRSP 3mg EP combination changed some parameters of skin quality, increasing corneometry (a parameter related to skin hydration), and reduced trans epidermal water loss (TEWL, a parameter related to skin evaporation), and erythema (a parameter related to skin inflammation). These results could be taken into account in individualizing the treatment of hyperandrogenic patients.

RESUMO

Chorioamnionitis is an inflammation of the placental membranes induced by microorganisms which reach the endometrial cavity from the vagina and uterine cervix. Premature labor frequently depends on infections. In patients with premature rupture of membranes (PROM) antibiotic treatment can prevent intra-amniotic inflammation if it is absent at admission. In spite of antibiotic treatment started immediately after the PROM in 218 patients, the chorioamnionitis did not prevent delivery in 41 patients within 48 hours of PROM. In the presence of a previous chorioamnionitis, antibiotic treatment cannot prevent premature labor, whereas it can prevent infection and lead to a longer duration of pregnancy if PROM does not depend on previous infection.

RESUMO

Urinary incontinence is a disease able to decrease the quality of life of affected women. It shows a prevalence of about 35% among adult women. Pharmacological treatment can be used when pelvic floor muscle training has failed or when it could be better to postpone or avoid surgery. Duloxetine, a selective serotonin and noradrenaline reuptake inhibitor (SNRI), can act effectively in treating stress urinary incontinence.

RESUMO

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women in reproductive age. As for the treatment of this disease the lack of a clear etiology for PCOS has led to a symptom-orientated treatment. However, the overall aims of treatment are to induce ovulation for women desiring conception, to reduce androgen levels, to reduce body weight and to reduce long-term health risks of diabetes mellitus and cardiovascular disease. Clomiphene citrate (CC) is recommended as first line treatment for induction of ovulation in patients with PCOS by virtue of its efficacy, safety, and ease of administration. Alternatives for CC-resistant patients include gonadotrophin therapy (better with low-dose step-up protocol) and laparoscopic ovarian diathermy. Recently, recombinant FSH (rFSH) has been introduced in clinical practice and it seems more effective than urinary FSH as demonstrated by a significantly higher number of follicles recruited and embryos obtained with a shorter treatment period. The addition of GnRH-agonist to the stimulation protocol for women affected by PCOS could reduce premature luteinization and increase cycle fecundity. Other drugs under investigation are metformin and cabergoline. Hirsutism is the manifestation of hyperandrogenemia in PCOS. The primary goal of the treatment of hirsutim is central or peripheral androgen suppression using 3 groups of drugs: inhibitors of androgen production (oral contraceptives, GnRH analogues), peripheral androgen blockers (cyproterone acetate, flutamide, finasteride and spironolactone), and insulin-sensitizing agents (metformin). Weight reduction and exercise could also improve not only menstrual disturbances and infertility, but also insulin resistance and its adverse metabolic con-sequences.

RESUMO

The authors investigated whether testosterone levels and testosterone availability differ between older lean subjects with and without Alzheimer's disease (AD). Sex hormone binding globulin (SHBG) and estradiol levels were higher, whereas the free androgenization index (FAI) was lower, in lean subjects with AD than in lean subjects without AD. Factors involved in the increase of SHBG secretion could have an important role in the lower testosterone availability of subjects with AD.

RESUMO

Oral contraceptives slightly deteriorate insulin sensitivity. The present study investigated whether they may further unbalance the glucose metabolism of lean women with polycystic ovary syndrome (PCOS). Women with PCOS were assigned to receive for 6 months the biphasic association of 40/30 micro g ethinyl estradiol (EE) and 25/125 micro g desogestrel (DSG; n = 10) or the monophasic association of 35 micro g EE and 2 mg cyproterone acetate (CPA; n = 10). Glucose tolerance was investigated by an oral glucose tolerance test (OGTT). Glucose utilization dependent [insulin sensitivity (SI)] or independent (Sg) of insulin was investigated by the minimal model method applied to a frequently sampled iv glucose tolerance test. EE/DSG increased the response of C peptide to OGTT (1413 +/- 113 vs. 2053 +/- 213 area under the curve; P < 0.009) and the C peptide/insulin ratio (0.085 +/- 0.01 vs. 0.134 +/- 0.01 area under the curve; P < 0.003). It also increased the Sg (0.026 +/- 0.002 vs. 0.034 +/- 0.003; P < 0.04) and decreased the SI (2.40 +/- 0.26 vs. 1.68 +/- 0.27; P < 0.01). EE/CPA did not modify responses to OGTT of glucose, insulin, C peptide, or C peptide/insulin ratio. It did not modify Sg and significantly increased SI (1.47 +/- 0.38 vs. 3.27 +/- 0.48; P < 0.04). The present study indicates that EE/CPA improves SI, whereas EE/DSG impairs SI, but improves insulin clearance. The long-term metabolic effects of these two compounds on women with PCOS require further investigations.

RESUMO

OBJECTIVE: To determine whether hyperinsulinemia has a negative effect on uterine blood supply in patients with polycystic ovary syndrome (PCOS). METHODS: Sixty-three patients with normal body mass index were included prospectively in the study: 48 had clinical and hormonal features of PCOS and 15 were normo-ovulatory. All patients underwent Doppler flow measurement of the uterine artery, and determination of serum concentrations of luteinizing hormone, follicle stimulating hormone, prolactin, estradiol, androgens, insulin and C-peptide during the early follicular phase of the menstrual cycle. The 48 PCOS-patients were divided into two groups according to the pulsatility index (PI) value of the uterine artery: Group 1, PI < 3; Group 2, PI >or= 3 and the groups were compared. RESULTS: The mean PI of the uterine artery (3.01 +/- 1.0 vs. 1.93 +/- 0.3, respectively) and fasting levels of insulin (50.9 +/- 9.3 vs. 40.3 +/- 10.9) and C-peptide (366.9 +/- 118.4 vs. 243.6 +/- 120.3) of PCOS-patients were significantly higher than those of the control group. No correlation was found between insulinemia and C-peptide and PI of the uterine artery and no significant difference was found in insulin and C-peptide levels among the two groups of PCOS-affected patients. Only the serum level of dehydroepiandrosterone sulfate was significantly higher in Group 2, and a direct correlation was found between PI values of the uterine artery and DHEAS plasma levels. CONCLUSION: Insulin and C-peptide do not seem to interfere with uterine perfusion in PCOS-affected patients.

RESUMO

The effects of oral contraceptives (OCs) on neurosteroid concentrations were evaluated in female rats and women. In rats, ethynylestradiol and levonorgestrel (0.030 and 0.125 mg, respectively, subcutaneously) administered daily for 6 weeks reduced the concentrations of pregnenolone (-41%) progesterone (-74%) and allopregnanolone (-79%) in the cerebral cortex; the plasma concentrations of these steroids were also reduced but by smaller extents. OC administration for 3 months also reduced the serum concentrations of pregnenolone, progesterone and allopregnanolone in women. Chronic administration of OCs in rats increased the abundance of gamma-aminobutyric acid type A (GABA(A)) receptor gamma 2L and gamma 2S subunit mRNAs and the relative protein in the cerebral cortex, while the amounts of various alpha and beta subunit mRNAs were unaffected. Ovariectomy did not modify the effect of OCs administration on the concentrations of neurosteroids in the rat cerebral cortex (but not in the plasma) as well as on the GABA(A) receptor gene expression, suggesting a direct effect of OCs in brain. Finally, rats treated with OCs exhibited an anxiety-like behavior in the elevated plus-maze test. These results indicate that long-term treatment with OCs induced a persistent reduction in the concentrations of pregnenolone, progesterone and its GABA(A) receptor-active metabolite, allopregnanolone, both in rats and women. In rats this effect was associated with a plastic adaptation of GABA(A) receptor gene expression in the rat cerebral cortex.

RESUMO

OBJECTIVES: to compare the patterns of a 17 beta-estradiol (E(2)) gel containing 0.6 mg/g (1.5 mg E(2) per day, Gelestra); with the transdermal delivery system (Estraderm TTS 50) applied every 3 days over a 14-day period to women in spontaneous or surgical menopause. METHODS: a single centre, open, randomised, parallel-group study was conducted. A total number of 33 postmenopausal women were enrolled. In 23 of them the menopause occurred spontaneously, while 10 women were bilaterally ovariectomized. Randomly, the subjects were treated with Estraderm TTS 50 (no. 8) or with Gelestra (no. 14). The pharmacokinetic study of the drugs was performed at the seventh, ninth and 14th day in Gelestra treated women and at the first, third and second day in Estraderm TTS 50 treated women. In fact, the seventh, ninth and 14th day of percutaneous treatment corresponds to the first, third and second day of application of the transdermal system application. Blood samples were taken by each subject at baseline and 1, 2, 3, 4, 8, 12 and 24 h after the gel or transdermal system application. In almost all samples the level of E(2) and estrone (E(1)) were evaluated. Statistical analysis was performed by comparing the two groups of treatment. The following parameters were assessed: mean E(2) and E(1) concentrations, E(2) peak serum concentration within interval from 0 to 72 h (C(max)), E(2) trough concentration within interval from 0 to 72 h (C(min)), area under the E(2) time concentration curve in the interval from 0 to 72 h (AUC((0-72))), the average E(2) concentration during the measurement interval, calculated by dividing AUC((0-72)) by 72 h (C(av)), E(1)/E(2) ratio, and percentage fluctuation (%Fluct) which is equal to 100 (C(max)-C(min)/C(max)). RESULTS: there was no significant difference in E(2) C(av) between the two treatments. However, significant differences in favour to the gel on the first day (first h) and on third day (72nd h) and in favour to the patch at the second day (48th h) were detected. C(max), E(1)/E(2) ratio and AUC((0-72)) were not statistically different, while a significantly higher C(min) for the gel was observed. Furthermore, the 90% confidence interval for AUC((0-72)) ratio (0.83-1.10) was within the commonly applied bioequivalence acceptance range (0.80-1.25). The %Fluct was significantly lower for Gelestra than for Estraderm TTS 50. CONCLUSIONS: although the mean E(2) and E(1)concentrations, C(max), E(1)/E(2) ratio and the AUC((0-72)) did not differ between the two E(2) treatments, the Gelestra treatment showed a lower day-to-day variation over the three day application, than the Estraderm TTS 50.

RESUMO

OBJECTIVE: To evaluate the effectiveness of vaginal danazol as progestin supplement to estrogen replacement therapy, and its interference with uterine and carotid artery flow compared with medroxyprogesterone-acetate (MPA), estrogen alone, and placebo. METHODS: Forty healthy women at least 12 months after natural menopause were randomly divided into four treatment groups: Group 1 (n=10), continuous transdermal estradiol (TE) (50 microg/day), plus a monthly 10-day course of MPA (10 mg/day); Group 2 (n=10), continuous TE plus a monthly 10-day course of vaginal danazol (200 mg/day); Group 3 (n=10), TE alone; Group 4 (n=10), placebo. At baseline and during the first, third, and sixth month of treatment, the endometrial thickness was assessed by transvaginal ultrasonography, while the pulsatility index (PI) of the carotid and uterine arteries was assessed by color Doppler. An endometrial biopsy was also performed before and after the treatment. RESULTS: At baseline, no significant differences between ages and other evaluated parameters were present in the four groups. In groups 1, 2, and 3, the values of carotid and uterine PI decreased significantly and similarly during the treatment, while in group 4 they were unchanged. In group 3 only, the endometrium was significantly thicker during treatment than before. No endometrial hyperplasia was present in the four groups at the end of the treatment. CONCLUSIONS: Vaginal danazol seems to be capable of counteracting the mitogenic effect of estrogen on the endometrium without reducing the effectiveness of estrogens to improve peripheral arterial perfusion.

RESUMO

PURPOSE: To evaluate whether polycystic ovary syndrome (PCOS) patients with different pulsatility index (PI) of uterine artery showed differences in their hormonal pattern. METHODS: Eighty-eight PCOS-affected patients and 15 controls were submitted to Doppler flow measurement of uterine artery; LH, FSH PRL, estradiol, and androgens concentration determination; and BMI evaluation during early follicular phase. RESULTS: The mean PI of uterine artery of PCOS patients was significantly higher than control group (2.97 +/- 0.9 vs. 1.89 +/- 0.2 respectively). The distribution of the PI'values was significantly different in the PCOS-affected patients and in control group. The plasma levels of DHEAS and BMI were significantly higher in PCOS patients with PI > or = 3 than in PCOS patients with PI < 3. CONCLUSION: High resistance in the uterine artery is present in PCOS patients, but a wide range PI values of uterine artery is present. BMI and DHEAS seem to be factors interfering with uterine perfusion.

RESUMO

OBJECTIVE: The effect of melatonin on human carbohydrate metabolism is not yet clear. We investigated whether melatonin influences glucose tolerance and insulin sensitivity in aged women. PATIENTS: Twenty-two postmenopausal women of whom 14 were on hormone replacement therapy. DESIGN: After an overnight fast, at 0800 hours on two nonconsecutive days, placebo or melatonin (1 mg) were administered randomly and in a double blind fashion. Forty-five minutes later, an oral glucose tolerance test (75 g; OGTT) was performed in 13 women. In another nine women insulin-dependent (Si) and -independent (Sg) glucose utilization was tested by a frequently sampled intravenous glucose tolerance test (FSIGT). RESULTS: Areas under the response curve to OGTT (AUC) for glucose (1420 +/- 59 vs. 1250 +/- 55 mmol x min/l; P < 0.01), and C-peptide (42,0980 +/- 45,320 vs. 33,528 +/- 15,779 pmol x min/l; P < 0.02) were higher following melatonin than placebo, while Si values were lower (2.6 +/- 0.28 units vs. 3.49 +/- 0.4 units; P < 0.03). Si modifications induced by melatonin were inversely related to Si values of the placebo day (r(2) = 0.538; P < 0.025). CONCLUSIONS: The present results indicate that in aged women administration of 1 mg of melatonin reduces glucose tolerance and insulin sensitivity. The present data may have both physiological and clinical implications.

RESUMO

The psychological symptoms assessed with a validated psychometric scale, SCL-90, were significantly higher in postmenopausal women (PMW; 60 subjects) than in premenopausal women (20 subjects). In the same PMW, the activity of the dopaminergic system, assessed with the PRL response to the dopamine-blocking agent sulpiride, was significantly lower than that in premenopausal women. During a period of 12 weeks the 60 PMW were randomly divided into 3 groups: no treatment (group A; n = 20), treatment with estradiol (E(2)) alone (patches with a E(2) release of 50 microg/24 h; group B; n = 20), and treatment with hormonal replacement therapy [estradiol valerate (EV) at a daily dose of 2 mg for 11 days and EV at the same daily doses plus cyproterone acetate (CPA) at a daily dose of 1 mg/day for 10 days; group C; n = 20). At the 12th week of the observation, only in group C women were the psychological symptoms significantly decreased, and the indirect evaluation of the dopaminergic system activity through PRL response to sulpiride showed a significant increase. During the same period, no changes in testosterone levels were observed in any group of PMW, whereas a significant increase in E(2) levels was found in both groups B and C. Although it is likely that the improvement in psychological symptoms with EV and CPA was due to progestin, we cannot rule out the possibility that greater estrogen exposure may have played a role.

RESUMO

The aim of the study was to evaluate if a pill containing the same dose of the same type of progestin compound (gestodene, GES, 75 microg) but different doses of ethinylestradiol (EE2) (20 or 30 microg) differently influences specific markers of bone resorption (urinary levels of pyridinoline (PYR) and dexoxypyridinoline (D-PYR)). During the 12 months of the study a significant decrease of urinary levels of PYR and D-PYR was found in 2 groups of young post-adolescent women taking the pills with 20 and 30 microg of EE2 in comparison with control women (subjects of the same age group with normal menstrual cycle who did not use contraception). In women taking pills with 20 or 30 microg EE2, the levels of sex hormone-binding globulin (SHBG) significantly increased during treatment in comparison with baseline, whereas in the same time period no changes occurred in control women. These findings suggest that similar to the pill containing 30 microg EE2, the lower dosage of the EE2 pill (20 microg) is also capable of reducing bone resorption. Twenty and 30 microg EE2 pills exert the same biological estrogenic effect. In fact, SHBG levels significantly increased with both pills. However, an additional effect of the progestin compound that could act directly on progestin or estrogen receptors of bone cannot be excluded. Since contraception with a pill containing the lowest estrogen dose is associated with the lowest incidence of side effects, these findings further suggest a pill containing 20 microg EE2 for young post-adolescent women would be the best choice.
