RESUMO

Premature ovarian failure (POF) defines the occurrence of ovarian failure prior to the age of 40. It occurs in one out of 100 women but is very rare before age 20 (1:10,000). Maturity-onset diabetes of the young (MODY), caused by mutations in the HNF1A gene, is also a rare disorder; all types of MODY account for 1-2% of adult diabetic cases. These two rare nosologic entities coexisted in an adolescent girl evaluated for delayed puberty. Although this combination could represent a chance association, an interrelation might exist. We examined HNF1A expression in human fetal and adult ovaries by immunohistochemistry using a polyclonal HNF1A antibody. HNF1A protein was expressed in both the fetal and adult human ovaries. Based on these findings, we hypothesize that HNF1A participates in ovarian organogenesis and/or function and that mutations in the HNF1A gene might represent another molecular defect causing POF, possibly in combination with other genetic factors. The study underlines the importance of rare clinical paradigms in leading the way to elucidation of the pathogenetic mechanisms of rare diseases.

RESUMO

PURPOSE: This study aims to assess the effectiveness of the non-ablative photothermal erbium laser (Er:YAG laser) for managing anterior and/or posterior vaginal compartment prolapse. METHODS: A randomized, single-blind, 1:1 trial was performed comparing Er:YAG laser treatment to watchful waiting in postmenopausal women with symptomatic cystocele and/or rectocele stage 2 or 3 who opted to undergo surgery due to bothersome prolapse symptoms. Three Er:YAG laser treatments at monthly intervals were applied for the Er:YAG laser group, while there was no treatment for the watchful-waiting group. The primary outcome was the proportion of patients with stage 0 or 1 following laser treatment, while secondary outcomes included the Pelvic Organ Prolapse Quantification System (POP-Q points), Pelvic Floor Distress Inventory Questionnaire short-form, Pelvic Floor Impact Questionnaire short-form, and Patients Global Impression of Improvement (PGI-I). All outcomes were evaluated at baseline and 4 months post baseline. RESULTS: Thirty women (15 vs. 15) were eligible to be included. No participants (0%) in either group had POP-Q stage 0 or 1 at 4 months. Moreover, no change was present in the secondary outcomes. In the PGI-I, 2/15 (14%) and 0/15 (0%) participants declared much better/very much better in the laser and watchful-waiting group, respectively. CONCLUSIONS: The findings of this study do not support use of the intravaginal Er:YAG laser for treatment of the anterior/posterior vaginal wall. Clinical trial identification number: NCT03714607.

RESUMO

For many decades adenomyosis has been a histological diagnosis in hysterectomy specimens. Traditionally, it has been considered a disease of late reproductive and premenopausal years causing uterine enlargement, dysmenorrhoea and menorrhagia. Recent advances in pelvic and uterine imaging techniques including transvaginal sonography and magnetic resonance imaging were responsible for a shift towards a non-invasive diagnosis and made a significant contribution to a better understanding of its pathogenesis, epidemiology, histological spectrum, and clinical symptomatology. With these non-invasive tools it has been shown that adenomyosis is probably a condition affecting much younger populations and is frequently asymptomatic at an early stage of its development. Regarding symptomatic disease, the distribution and extent of adenomyotic lesions do not correlate consistently with the various symptoms that are considered typical of adenomyosis. More importantly, accurate diagnosis of adenomyosis suffers from a lack of consensus among experts on imaging and even histological diagnostic criteria. Several pathogenetic theories have attempted to shed light on the establishment, evolution and distribution of adenomyotic lesions within the uterine wall, including the tissue injury and repair (TIAR) mechanism, metaplasia, and the more recent genetic-epigenetic theory. So far, none of these can adequately and independently explain the appearance of all types of adenomyosis. This review paper attempts a correlation between the proposed pathogenetic theories and the clinical and histological spectrum of adenomyosis, in an effort to give a plausible explanation of the evolution of this condition from an asymptomatic state to a disease, through synthesis of the existing data.

RESUMO

BACKGROUND: Training in hysteroscopy can be challenging, especially in conscious women as an office procedure. OBJECTIVE: To develop a realistic hysteroscopy training model for residents using human uteri. METHODS: Human uterine specimens were acquired immediately after hysterectomy, before they were sent for histological analysis and were used as a training model for hysteroscopy. RESULTS: We describe this new technique, which we have used for one year in our resident training programme. Each resident performs at least 20 simulated diagnostic hysteroscopies in extirpated uteri, before performing procedures on women in the operating room. CONCLUSIONS: Simulating hysteroscopy on human uterine models offers a novel and realistic way of training novices prior to conducting procedures under supervision on live patients. WHAT IS NEW: This is a novel model for training and offers a much more realistic training opportunity.

RESUMO

OBJECTIVE: To assess the effect of non-steroidal anti-inflammatory drugs (NSAIDs) on blood pressure when administered for postpartum analgesia in women with hypertensive disorders of pregnancy. METHODS: MEDLINE, Scopus, CENTRAL, Clinicaltrials.gov and Google Scholar databases were searched systematically from inception to 5 December 2019 for studies evaluating the safety of postpartum NSAIDs in women with any gestational hypertensive disorder. Randomized controlled trials (RCTs) and cohort studies were eligible for inclusion. Case-control studies, case series and case reports were excluded. The primary outcomes of interest were the incidence of severe hypertension and systolic, diastolic and mean arterial blood pressure. Pooled estimates were obtained by fitting a random-effects statistical model. The quality of evidence was assessed according to Grading of Recommendations, Assessment, Development and Evaluations (GRADE) guidelines. RESULTS: Ten studies were included, comprising five RCTs and five retrospective cohort studies and involving a total of 1647 women. All studies were evaluated qualitatively and eight of them were included in the quantitative meta-analysis. Administration of NSAIDs was not associated with a significantly higher risk of severe postpartum hypertension (odds ratio, 1.52 (95% CI, 0.77-3.01)). Similarly, no significant differences were found in postpartum systolic blood pressure (mean difference (MD), -3.03 mmHg (95% CI, -6.21 to 0.15 mmHg)) and mean arterial pressure (MD, -0.38 mmHg (95% CI, -1.88 to 1.11 mmHg)) between women who received NSAIDs and those who did not, whereas postpartum diastolic blood pressure was marginally lower in women treated with NSAIDs (MD, -2.28 mmHg (95% CI, -4.44 to -0.13 mmHg)). The same effects were observed when studies with a large sample size, RCTs, women with severe pre-eclampsia and studies using ibuprofen as the study drug and acetaminophen as the control treatment were examined separately. The credibility of evidence was judged to be very low according to GRADE, owing to concerns about study limitations, inconsistency and imprecision. CONCLUSIONS: This meta-analysis suggests that postpartum administration of NSAIDs is not associated with elevated blood pressure in women with hypertensive disorders of pregnancy. However, the existing evidence is of very low quality, thus future large-scale RCTs are warranted to verify the safety of postpartum NSAIDs in this population. Copyright © 2020 ISUOG.

RESUMO

Objectives: Sexual dysfunction and radiation cystitis are common adverse events following radiotherapy for gynecological cancer (GC). This study aims to assess the efficacy of intravaginal CO2 laser on GC survivors with dyspareunia following pelvic radiation and/or brachytherapy.Methods: This is the study protocol of a randomized double-blind placebo-controlled trial. All participants will receive five therapies (active or placebo) at monthly intervals. Outcomes will include a 10-cm visual analog scale measuring dyspareunia, vaginal dryness, and other symptom intensity, 3-day voiding diary, Day-to Day Impact of Vaginal Aging questionnaire, Female Sexual Function Index, European Organization for Research and Treatment of Cancer Quality of Life questionnaire cervical cancer module, Urogenital Distress Inventory short form, King's Health Questionnaire, International Consultation on Incontinence Questionnaire short form/female lower urinary tract symptoms, patient perception of improvement, sexual satisfaction of male partners, vaginal maturation value, and Vaginal Health Index. Differences between groups will be assessed at baseline and 1, 3, 6, 9, and 12 months following the five laser therapies.Results: As this is a study protocol, the study is ongoing with an expected end of recruitment and analysis date of 2021.Conclusion: Pelvic radiotherapy for GC increases the 5-year survival rate but with a negative impact on women's quality of life due to sexual dysfunction and radiation cystitis onset. With this study, CO2 laser therapy will be evaluated for the first time in GC survivors treated with radiotherapy. ClinicalTrials.gov registration number: NCT03714581.

RESUMO

BACKGROUND: The emphasis on aesthetic outcomes and quality of life after breast cancer surgery has motivated breast surgeons to develop oncoplastic breast conserving surgery (OPS). Training programs are still rare in most countries, and there is little standardization, which challenges the scientific evaluation of these techniques. This systematic review aims to assess oncological and cosmetic outcomes of OPS. METHODS: After a strict selection process with precise inclusion and exclusion criteria, oncologic and aesthetic outcomes of oncoplastic surgery were searched, using the MEDLINE database up to September 30th, 2017. Available published literature was classified in levels of evidence. After a thorough screening process, only studies with the best level of evidence were included on selection. Systematic reviews and meta-analyses were not included for methodological reasons. RESULTS: Titles and abstracts of 2.854 citations were identified and after screening 15 prospective studies including 1.391 patients were reviewed and scored in detail. Local relapse was found in 2.8% of cases with a wide range of follow-up (from 6 to 74 months). Close margins were retrieved in 11% of cases and positive margins in 9.4% of cases. Mastectomy was implemented in 6.9% of breast cancer patients to whom OPS was performed. Good cosmetic outcomes were detected in 90.2% of patients undergoing OPS, leaving open issues for who should perform cosmetic evaluation and which method should be used. CONCLUSION: Tumor margins, mastectomy rates, and cosmetic outcomes of OPS have to be further improved by standardizing various aspects of OPS. Research efforts should focus on level I evidence assessing both oncological and aesthetic outcomes of OPS and survival rates.

RESUMO

The traditional method of acquiring surgical skills by observing and assisting in surgical procedures involving human beings has been challenged during the past several years. Lessons obtained from aviation suggested that the use of simulators is related to reduced costs, increased efficiency in performing certain tasks and above all safety. A shift in paradigm is also required in modern surgical training. The development of endoscopic surgery allowed for the incorporation of medical simulators into training programmes. A review of the literature was conducted using specific inclusion and exclusion criteria, for articles published up to July 31th, 2018. Relevant studies were identified using computerized bibliographic searches of MEDLINE database. The keywords that were used in various combinations were: "Medical Simulators", "Surgical Training", "Laparoscopy", "Surgical Skills", "Box trainers", "Virtual reality simulators", "Surgical Education". Surgical training with box trainers and/or virtual reality simulators confers a significant benefit in terms of surgical skills development, increases patient safety and reduces costs. Nevertheless, the use of virtual reality simulators was significantly more expensive. Simulation training allows trainees to learn from their mistakes, to repeat surgical tasks multiple times so as to establish muscle memory, and enhance skill competency with the aid of informative feedback. Simulators are necessary for the development of the skills required to meet the specific needs of endoscopic surgery in the 21st century. Teaching hospitals should introduce simulation training programmes in order to increase efficiency, reduce costs and improve patient safety. As medical advancements continue to transform the way we perform surgery day by day, simulation training will play a pivotal role in every surgical specialty.

RESUMO

PURPOSE: History of fetal loss including miscarriage and stillbirth has been inconsistently associated with childhood (0-14 years) leukemia in subsequent offspring. A quantitative synthesis of the inconclusive literature by leukemia subtype was therefore conducted. METHODS: Eligible studies (N = 32) were identified through the screening of over 3500 publications. Random-effects meta-analyses were conducted on the association of miscarriage/stillbirth history with overall (AL; 18,868 cases/35,685 controls), acute lymphoblastic (ALL; 16,150 cases/38,655 controls), and myeloid (AML; 3042 cases/32,997 controls) leukemia. Sensitivity and subgroup analyses by age and ALL subtype, as well as meta-regression were undertaken. RESULTS: Fetal loss history was associated with increased AL risk [Odds Ratio (OR) 1.10, 95% Confidence Intervals (CI) 1.04-1.18]. The positive association was seen for ALL (OR 1.12, 95%CI 1.05-1.19) and for AML (OR 1.13, 95%CI 0.91-1.41); for the latter the OR increased in sensitivity analyses. Notably, stillbirth history was significantly linked to ALL risk (OR 1.33, 95%CI 1.02-1.74), but not AML. By contrast, the association of ALL and AML with previous miscarriage reached marginal significance. The association of miscarriage history was strongest in infant ALL (OR 2.34, 95%CI 1.19-4.60). CONCLUSIONS: In this meta-analysis involving >50,000 children, we found noteworthy associations by indices of fetal loss, age at diagnosis, and leukemia type; namely, of stillbirth with ALL and miscarriage history with infant ALL. Elucidation of plausible underlying mechanisms may provide insight into leukemia pathogenesis and indicate monitoring interventions prior to and during pregnancy.

RESUMO

PURPOSE: The aim of the study was to assess the eftect ot the addition or iow-cose numan cnononic gonauoiropm (hCG) to ovarian stimulation with recombinant follicle stimulating hormone (rFSH) on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcome. MATERIALS AND METHODS: This retrospective clinical study was conducted on 141 women undergoing ICSI through a short GnRH-agonist protocol with rFSH and the addition of low-dose (100 IU/day) hCG. The control group consisted of 124 women undergoing ovarian stimulation with a similar protocol devoid of hCG. Statistical analysis in the study population along with a subgroup analysis for age 35 years and 36 years was performed. RESULTS: Women in hCG group were statistically significant older and with higher basal FSH compared to control group. This can be attributed to the Centre's latent tendency to add hCG in the stimulation protocol in poor prognosis patients. Despite this fact and the fact that several ovarian stimulation parameters, such as peak estradiol levels, number of oocytes retrieved, number of mature oocytes, and fertilization rates were in favor of the control group, the quality of transferred embryos and pregnancy rates were in favor of hCG group. Similar results were obtained in the subgroup analyses apart from peak estradiol levels, which did not differ among the study groups. CONCLUSIONS: The addition of hCG to rFSH may be associated with better quality embryos and higher pregnancy rates, even in women of advanced reproductive age with higher basal FSH levels, which are often considered to have poorer ovarian reserve.

RESUMO

In vitro growth systems of preantral follicles allow studying the effect of various endocrine, paracrine, and autocrine factors on follicular growth and oocyte maturation. CRH is a 41-amino-acid neuropeptide responsible for endocrine, autonomic, immunological, and behavioral responses of mammals to stress and has two receptors, CRH receptor type 1 (CRH-R1) and CRH-R2. Antalarmin, a CRH-R1 antagonist, has been used to elucidate the role of CRH in stress, inflammation, and reproduction. The present study describes in vitro growth of mouse preantral follicles, early embryo development, and steroidogenesis in the presence of CRH and its antagonist antalarmin. We cultured 732 follicles in control media, 1306 in CRH 10(-7) mol/liter, and 1202 in CRH 10(-7) plus antalarmin 10(-6) mol/liter. The culture medium was assayed on alternate days for 17ß-estradiol, progesterone, and ß-human chorionic gonadotropin. Total RNA was extracted from preantral follicles as well as early preimplantation embryos and was assessed by real-time RT-PCR for the expression of CRH-R1 and CRH-R2 mRNAs. Hormone analysis showed that the CRH group had lower levels of 17ß-estradiol, progesterone, and ß-human chorionic gonadotropin as the culture progressed, in comparison with the other two groups. RT-PCR demonstrated the presence of CRH-R1 and CRH-R2 in all stages of preantral follicle culture. Morula/blastocyst-stage embryos expressed only CRH-R1. In conclusion, CRH has an inhibitory effect on in vitro fertilized oocytes, resulting from cultured preantral follicles at all stages of preimplantation embryo development. Furthermore, the presence of CRH in the culture medium inhibits steroidogenesis by preantral mouse follicles cultured in vitro.

RESUMO

Obtaining an adequate number of good quality oocytes while minimizing adverse drug reactions (ADRs) and cycle cancellation rates is considered the gold standard in controlled ovarian hyperstimulation (COH) for fertility treatment. Patients who undergo IVF/ICSI cycles tend to present with different responses to exogenous gonadotrophin administration. Research has shown that the secret probably lies in the various single nucleotide polymorhisms (SNPs) in their receptor genes. The decryption of human genome provided specialists with additional information in assessing and even predicting ovarian response to COH. In this context, the study of Pharmacogenomics, Pharmacogenetics and SNPs unravels as a promising field in optimizing fertility treatment. Several SNPs in FSH and estrogen receptor genes have been detected so far, but only three of them, one in FSH receptor and two in estrogen receptor genes have been associated with ovarian response to COH. It seems that the Asn/Ser variant of the FSH receptor functions more efficiently, while the Ser/Ser and Asn/Asn variants have a tendency to resist to FSH stimulation. With regards to estrogen receptor 1 (ESR1), the Pvull and the Xbal polymorphisms seem to be associated with differences in the response to ovarian stimulation, while the Rsal polymorphism in estrogen receptor 2 (ESR2) is currently under investigation. There exists evidence supporting the hypothesis that a set of genes, all related to the FSH hormone mechanism of action, may participate along with other factors to the control of ovarian response to FSH, thus a cautious interpretation of polymorphism detection results is considered mandatory. However, identifying potential genetic markers that could predict ovarian response and implementing them in routine screening tests for every woman entering an IVF/ICSI cycle, would be able to tailor fertility treatment to each patients needs thus maximizing the success rate and eliminating potential side-effects of fertility drugs.

RESUMO

PURPOSE: Previous studies in humans concluded that a multigenic model including specific FSHR, ESR1 and ESR2 genotype patterns may partially explain the poor response to FSH. The aim of our study is to analyse three different loci -polymorphisms in ESR1 Pvu II, ESR2 Rsa I and Ser680Asn FSH receptor gene- in a Greek population and their involvement in stimulation outcome and pregnancy rates. METHODS: Each locus was studied alone, and in combination with the others. We performed both restriction fragment length polymorphism analysis and real-time polymerase chain reaction. A total of 109 normally ovulating female patients underwent IVF or ICSI. RESULTS: Studying each locus alone, no significant results were drawn for ESR1 and ESR2 genes. Concerning the FSHR polymorphism, the women carrying the AA variant presented higher total amount of gonadotrophins used (P=0,048) and tended to have higher number of stimulation days (P=0,057). Considering the ESR1 and FSHR gene polymorphisms in combination, the TC/SA combination presents the highest number of pregnancies in poor responders group (3/4 pregnancies carried this genotype), in good responders group (4/12 pregnancies carried this genotype) and in the total population (10/26 pregnancies carried this genotype). Except the CC/AA combination, all other genotype combinations presented incidence of pregnancy, with TC/SA having the highest incidence. The CC/AA genotype presents the worst profile of ovulation induction, confirming a poor responder profile: the total amount of gonadotrophins used was highest in CC/AA group (P < 0,05). The peak E2, the number of follicles and of retrieved oocytes and the pregnancy rate were significantly lower (P < 0,05). This genotype combination seems to be over-presented in the poor responders group in a statistically significant way (P=0,038). Women with CC/AA combination have 1,5-2,4 times more risk to be poor responders in comparison with women that do not carry that combination. CONCLUSION: This study supports the hypothesis that a multigenic model, including the well studied ESR1 and FSHR genes is involved in the controlled ovarian stimulation outcome indicating that the CC/AA genotype presents the worst ovulation induction profile, while the TC/SA genotype presents the higher number of pregnancies in our population.

RESUMO

Men with Down syndrome are considered as infertile although the causes of infertility are not known in detail yet. Although this constitutes a general rule there are three confirmed cases of parenting by fathers with Down syndrome. Many investigators have addressed the causes of infertility and their studies indicate that the causes may be hormonal deficits, morphological alterations of the gonads, abnormal spermatogenesis, psychological and social factors related to the mental retardation. It is obvious that the extra chromosome 21 has a detrimental direct and indirect effect on the reproductive capacity of the affected male patient. But the definite cause of the insufficient and inadequate spermatogenesis remains to be discovered.

RESUMO

The advent of recombinant technology has made the production of modified proteins with desired properties possible. Corifollitropin alfa is a successful example of the first available long-acting, follicle stimulating hormone. Corifollitropin alfa has prolonged half-life and a slower absorption rate, but has the same receptor-binding and biological activity as recombinant FSH (rFSH). Its application is associated with the arrival of a novel simplified approach for controlled ovarian stimulation in IVF patients. Different studies have proven the efficiency of a single corifollitropin alfa dose to initiate and sustain multiple follicular development in a gonadotropin-releasing hormone antagonist protocol. Finally, corifollitropin alfa is well tolerated and is not correlated with serious adverse events, except for the slightly higher incidence of ovarian hyperstimulation syndrome compared with traditional management with recombinant FSH.

RESUMO

Spinal cord injury (SCI) in men results in defects in erectile function, ejaculatory process and male reproductive potential. There are alterations in the capacity of men with SCI to achieve reflexogenic, psychogenic and nocturnal erections. The sexual function in different stages after SCI and the types of erections depend mainly on the completeness of the injury and the level of neurological damage. Furthermore, most of the SCI men demonstrate defects concerning the entrance of semen into the posterior urethra and the expulsion of the semen through the penile urethra and the urethral orifice. In addition, SCI men develop defects in the secretory function of the Leydig cells, Sertoli cells and the male accessory genital glands. The overall result is a decreased quality of the semen is recovered either with penile vibratory stimulation (PVS) or with electroejaculation. Nowadays the therapeutic andrological approach of SCI men focuses on achievement of erectile function, recovery of spermatozoa and assisted reproductive technology. The first line of therapy recommended for infertility in SCI men is collection of semen via PVS with concomitant evaluation of total motile sperm yields for assisted conception which may include intravaginal insemination, intrauterine insemination, or in vitro fertilisation/intracytoplasmic sperm injection. Patients failing PVS may be referred for electroejaculation or surgical sperm retrieval.

RESUMO

The goal was to examine prospectively the relation of psychological factors to the outcome after in vitro fertilization (IVF) in a sample of Greek women. Previous studies investigating the relation of IVF outcome to anxiety and depression have yielded contradictory results; other psychological dimensions have not been studied. 81 women who followed an IVF program during a 6-mo. period were prospectively evaluated. Demographic and gynecological data were assessed and women completed questionnaires measuring anxiety, depression, narcissistic traits, over-dependency, self-esteem, hostility, and alexithymia. Multiple logistic regression analysis showed that successful IVF outcome correlated with more alexithymic characteristics and younger age. Correlation between alexithymia and successful IVF outcome is demonstrated.
