Objective: The conservative treatment of endometrial hyperplasia without atypia (HWA), atypical endometrial hyperplasia (AH/EIN) and early endometrioid carcinoma (EEC) is based on progestins. We aimed to assess whether diabetes mellitus affects the responsiveness of HWA, AH/EIN and EEC to conservative treatment, through a systematic review and meta-analysis. Study design: Electronic databases were searched for studies assessing the outcome of conservative treatment in HWA, AH/EIN and EEC, stratified based on the diagnosis of diabetes mellitus. The association of diabetes mellitus with treatment failure was assessed by using odds ratio (OR). A p -value  < .05 was considered significant. The risk of publication bias was assessed by using a funnel plot. A subgroups analyses was performed based on histologic diagnosis of benignity (HWA) or premalignancy/malignancy (AH/EIN or EEC). Results: Six studies with 876 patients (383 HWA, 365 AH/EIN and 128 EEC) were included. Overall, diabetes mellitus was not associated with outcome of treatment (OR = 1.20; p  = .62). The association was not significant in both the HWA subgroup (OR = 0.95; p  = .93) and in AH/EIN and EEC subgroup (OR = 1.43; p  = .46). There was no significant risk of publication bias. Conclusions: Diabetes mellitus does not affect the outcome of conservative treatment in HWA, AH/EIN and EEC.

The aim of this multicentre, prospective, randomised, investigator blind, controlled clinical trial was to evaluate the clinical efficacy and tolerability of a highly purified human menopausal gonadotrophin (hMG) preparation (Merional-HG) when administered to patients undergoing controlled ovarian stimulation (COS) for in-vitro fertilisation (IVF) procedure enrolled in hospital departments. One hundred fifty-seven patients were randomised in two parallel groups: 78 started COS with Merional-HG and 79 with Menopur. Results of the study showed that both highly purified hMG preparations were equivalent in terms of number of oocytes retrieved (primary endpoint: 8.8 ± 3.9 versus 8.4 ± 3.8, p = 0.54). In the patients treated with Merional-HG, we observed a higher occurrence of mature oocytes (78.3% versus 71.4%, p = 0.005) and a reduced quantity of gonadotrophins administered per cycle (2.556 ± 636 IU versus 2.969 ± 855 IU, p < 0.001). Fertilisation, cleavage, implantation rates and the number of positive β-human chorionic gonadotrophin (hCG; pregnancy) tests and the clinical pregnancy rate were comparable in the two groups. Both treatments were well tolerated. In conclusion, the results of this study support the efficacy and safety of Merional-HG administered subcutaneously for assisted reproduction techniques. Efficiency of Merional-HG appears to be higher due to reduced quantity of drug used and the higher yield of mature oocytes retrieved.

A total of 3,324 singleton pregnant women were screened for pre-term delivery and 128 women were finally randomised and analysed for outcome showing borderline cervical length (25-29 mm) and elevated cervico-vaginal interleukin 6 levels. To verify if vaginal administration of lactoferrin might have an influence on these variables, two groups of 64 patients were formed. Study cases were submitted to lactoferrin for 21 days; controls received no treatment. An inverse relation was found between interleukin 6 levels and cervical length. On day 30 from the beginning of the treatment, study cases showed a decrease in interleukin 6 levels and an increase in cervical length. A greater number of women with regular uterine contractions and reduced cervical consistency before the 37th week of gestation were found in the controls. Our data show that lactoferrin could play a role in reducing the number of women at risk for pre-term birth for shortened cervical length and elevated interleukin 6 levels.

Some studies have suggested a possible role of leptin, an active cytokine produced by adipocytes, in the pathogenesis of pelvic endometriosis. The present study was designed to assess leptin levels in the peritoneal fluid (PF) of women with the 'deep' or 'superficial' types of ovarian endometriosis. Twenty-seven women with a single ovarian endometrioma having a mean diameter between 3 and 5 cm were included in the study. Patients were divided into two groups according to the type of ovarian endometriosis: Group A (n = 11) consisted of women with 'superficial' endometriomas located at the ovarian surface; Group B (n = 16) included patients with 'deep' intra-ovarian endometriomas. Women undergoing laparoscopy for unexplained infertility and not affected by pelvic and/or ovarian endometriosis were considered as controls (Group C, n = 10). Patients with an ovarian endometrioma had significantly increased PF leptin concentrations than endometriosis-free controls (Groups A and B vs. Group C, p < 0.01). Patients with 'superficial' endometriomas had significantly higher PF leptin levels compared with patients with 'deep' endometriomas (Group A vs. B, p < 0.01). This difference remained significant after correction for the BMI; moreover, a positive correlation between PF leptin and BMI was observed in Groups B and C, but not in women with 'superficial' endometrioma (Group A). Our observations suggest that: (a) leptin could play an active role in promoting the development of 'superficial' ovarian endometriomas and (b) 'superficial' and 'deep' ovarian endometriomas could have a different pathogenesis.

Our objective was to compare the effectiveness and safety of atosiban and ritodrine, in pregnancies obtained by intracytoplasmic sperm injection (ICSI) undergoing cervical cerclage. Data from a prospective study were compared with those from a retrospective study. Sixteen ICSI pregnant women, 20-24 weeks' gestation and maternal age >18 years, received atosiban (bolus dose 6.75 mg i.v., followed by 300 microg/min i.v. for 3 h and 100 microg/min i.v. for 45 h). Cervical cerclage was performed 3 h after starting atosiban. The control group (group B) of 16 ICSI pregnant women were matched and received ritodrine hydrochloride (100-350 microg/min) for 48 h. Cervical cerclage was performed after 24 h. Pre-term rupture of membranes occurred within 48 h of cervical cerclage in one woman receiving atosiban and in four women receiving ritodrine. There was no significant difference in terms of pregnancies not delivered at 48 h (short-term tocolysis) and at 7 days (long-term tocolysis). However, there was a significantly higher incidence of maternal tachycardia with ritodrine compared with atosiban (p < 0.001). The mean gestational age at delivery was significantly higher for atosiban compared with ritodrine (36 vs 33 weeks; p < 0.001). The neonatal outcome was poorer for ritodrine than atosiban, as there were very low birth weight infants (p = 0.008), resulting in lower Apgar scores (p = 0.005) and there were more neonates requiring a long stay in the neonatal intensive care unit (p = 0.005). We conclude that atosiban is associated with a significantly lower incidence of maternal tachycardia and improved neonatal outcome compared with ritodrine.
