Laparoscopic vs vaginal hysterectomy for benign pathology

OBJECTIVE The objective of the study was to compare length of stay, blood loss, operative time, and pain of laparoscopic and vaginal hysterectomy. STUDY DESIGN This was a prospective, randomized, controlled comparison between vaginal (VH) and laparoscopic (LH) hysterectomy among 60 consecutive patients with a uterine volume of 300 mL or less and without uterine prolapse. Patients were followed up for 12 months. RESULTS The groups were significantly different for mean operative time (VH: 81 +/- 30 minutes; LH: 99 +/- 25 minutes; P = .033) and blood loss (LH: 83 +/- 57 mL; VH: 178 +/- 149 mL; P = .004). Bilateral adnexectomy was performed when preoperatively planned in 73% of cases of the vaginal arm, whereas it was always performed in the laparoscopic arm (P = .045). Postoperative pain on day 0 and the number of days of analgesic request were higher in the vaginal group (P = .023 and P = .017, respectively). LH was associated with a reduced hospital stay (LH: 2.7 +/- 0.5 days; VH: 3.2 +/- 0.6 days; P < .001).There were no differences between the groups at the follow-up. CONCLUSION Laparoscopic hysterectomy results in a shorter hospital stay, less blood loss, and less postoperative pain compared with vaginal hysterectomy.

Fimbrial cells exposure to catalytic iron mimics carcinogenic changes

Objective Recent evidence strongly suggests that the fallopian tube is a site of origin of ovarian cancer. Although histological data show iron deposition in the fallopian tubes, its role remains unclear. To establish whether catalytic iron has a possible role in ovarian carcinogenesis, we isolated human fimbrial secretory epithelial cells (FSECs). Methods Fimbrial secretory epithelial cells, isolated from women undergoing isteroannessiectomy, were treated with different doses of catalytic iron (0.05–100 mM) to study cell viability; NO production; p53, Ras, ERK/MAPK, PI3K/Akt, Ki67, and c-Myc protein expressions through Western blot analysis; and immunocytochemistry or immunofluorescence. Results In FSECs treated with catalytic iron for up to 6 days, we observed an increase in cell viability, NO production, and p53, pan-Ras, ERK/MAPK, PI3K/Akt, Ki67, and c-Myc activations (P < 0.05) in a dose-dependent and time-dependent manner. These same results were also observed in FSECs maintained for respectively 2 and 4 weeks in the absence of catalytic iron after 6 days of stimulation. Conclusions Our model aimed at studying the main nongenetic risk factor for ovarian cancer, providing an alternative interpretation for the role of menstruation in increasing risk of this pathology. This in vitro model mimics several features of the precursor lesions and opens new scenarios for further investigations regarding the correlation between damages produced by repeated retrograde menstruation carcinogenic stimuli.

Coffee and caffeine intake and male infertility: a systematic review

BackgroundSemen quality, a predictor of male fertility, has been suggested declining worldwide. Among other life style factors, male coffee/caffeine consumption was hypothesized to influence semen parameters, but also sperm DNA integrity. To summarize available evidence, we performed a systematic review of observational studies on the relation between coffee/caffeine intake and parameters of male fertility including sperm ploidy, sperm DNA integrity, semen quality and time to pregnancy.MethodsA systematic literature search was performed up to November 2016 (MEDLINE and EMBASE). We included all observational papers that reported the relation between male coffee/caffeine intake and reproductive outcomes: 1. semen parameters, 2. sperm DNA characteristics, 3. fecundability. All pertinent reports were retrieved and the relative reference lists were systematically searched in order to identify any potential additional studies that could be included.ResultsWe retrieved 28 papers reporting observational information on coffee/caffeine intake and reproductive outcomes. Overall, they included 19,967 men. 1. Semen parameters did not seem affected by caffeine intake, at least caffeine from coffee, tea and cocoa drinks, in most studies. Conversely, other contributions suggested a negative effect of cola-containing beverages and caffeine-containing soft drinks on semen volume, count and concentration. 2. As regards sperm DNA defects, caffeine intake seemed associated with aneuploidy and DNA breaks, but not with other markers of DNA damage. 3. Finally, male coffee drinking was associated to prolonged time to pregnancy in some, but not all, studies.ConclusionsThe literature suggests that caffeine intake, possibly through sperm DNA damage, may negatively affect male reproductive function. Evidence from epidemiological studies on semen parameters and fertility is however inconsistent and inconclusive. Well-designed studies with predefined criteria for semen analysis, subject selection, and life style habits definition, are essential to reach a consistent evidence on the effect of caffeine on semen parameters and male fertility.

Creation of a Neovagina by Laparoscopic Modified Davydov Vaginoplasty in Patients with Partial Androgen Insensitivity Syndrome

STUDY OBJECTIVE To evaluate the feasibility, safety, and outcome of laparoscopic modified Davydov vaginoplasty in subjects with partial androgen insensitivity syndrome (PAIS). DESIGN A retrospective cohort study (Canadian Task Force classification III). SETTING A tertiary referral center. PATIENTS Ten continuous patients operated on between October 2008 and May 2014. INTERVENTIONS Laparoscopic modified Davydov vaginoplasty. The surgical technique was tailored on PAIS subjects who presented a male pelvic anatomy and, frequently, anomalies of the external genitalia. MEASUREMENTS AND MAIN RESULTS Anatomic success was defined as a neovaginal width allowing the insertion of 2 fingers and a neovaginal length of at least 5 cm. Functional success was defined as the presence of regular sexual intercourse. Laparoscopic modified Davydov vaginoplasty was successfully performed in all patients without surgical complications. At hospital discharge, anatomic success was achieved in all patients. At the 12-month follow-up, anatomic success was achieved in 9 patients and functional success in 7 patients. Two patients with anatomic success did not start any sexual activity by personal choice. One patient had an anatomic failure with a neovaginal length of 2 cm. This patient had not complied with the postoperative use of vaginal dilators. CONCLUSION This is the first study reporting the outcomes of laparoscopic modified Davydov vaginoplasty in subjects with PAIS. Postoperative long-term outcomes were comparable with those achieved in women with Rokitansky syndrome. The laparoscopic modified Davydov operation may represent the procedure of choice for the creation of a neovagina and the concomitant correction of anomalies of the external genitalia in subjects with PAIS.

Fetal Doppler changes 1 week after endoscopic equatorial laser for twin‐to‐twin transfusion syndrome: A longitudinal study

Women’s recall of requirements for oral contraception prescription in Italy

In Italy the use of oral contraceptives (OCs) is low in comparison with other countries,1 possibly because bimanual pelvic examination and laboratory tests are required before they can be prescribed. Such requirements may stop OCs being used, particularly by teenagers and young women, and so should be considered only in selected cases.2–4 We investigated the recall of these requirements by teenagers and young women in an online anonymous questionnaire on Facebook. Duplicate responses were ignored. A total of 842 women (mean age 21.5 (SD 1.7) years) completed the questionnaire; 236 smoked cigarettes, 177 had graduated from university, and 13 …

Concordance of vitamin D peripheral levels in infertile couples’ partners

Abstract A large number of evidence supports the role of vitamin D insufficiency in both women and men infertility. However, no studies have evaluated the rate of concordance of vitamin D status between the partners. This finding might open new scenarios in the interpretation of the available data linking vitamin D insufficiency and infertility. In the present cross-sectional study, 103 consecutive infertile couples were recruited between April and May 2014. Both partners concomitantly provided a serum sample for the assessment of 25-hydroxy-vitamin D [25-(OH)-D]. Vitamin D insufficiency was defined as serum 25-(OH)-D <20 ng/ml. One hundred-fifty subjects (73 women and 77 males) were 25-(OH)-D insufficient, corresponding to a rate of 73%. Overall, concordance was observed in 73 couples (71%), thus higher than the expected 61% (0.732 + 0.272) based on chance (p = 0.007). The Pearson coefficient of correlation R2 between the partners of the couples was 0.52 (p < 0.001). No statistically significant differences emerged when evaluating the rate of 25-(OH)-D insufficiency according to the causes of infertility. Serum 25-(OH)-D correlates within the partners of infertile couples. Further evidence is warranted to determine the clinical relevance and possible clinical applications of this finding.

Medical Management of Endometriosis

Current approved medical therapies for endometriosis rely on drugs that suppress ovarian steroids and induce a hypoestrogenic state, which determines the atrophy of the ectopic endometrium. Gonadotropin-releasing hormone analogs such as danazol, progestogens and estrogen–progestin combinations have all proven effective in relieving pain and reducing the extent of endometriotic implants. However, symptoms often recur after discontinuation of therapy and hypoestrogenism-related side effects limit the long-term use of most medications. Recently, knowledge of the pathogenesis of endometriosis, particularly at the molecular level, has grown substantially, providing a rational basis for the development of new drugs with precise targets that may be safely administered over the long term.
