RESUMO

PURPOSE: Information on the general health of transgender and gender diverse (TGD) individuals continues to be lacking. To bridge this gap, the National Institute of Health in Italy together with the National Office against Racial Discriminations, clinical centres, and TGD organizations carried out a cross-sectional study to define the sociodemographic profile, health-related behaviours, and experiences of healthcare access in Italian TGD adult population. METHODS: A national survey was conducted by Computer-Assisted Web Interviewing (CAWI) technique. Collected data were compared within the TGD subgroups and between TGD people and the Italian general population (IGP). RESULTS: TGD respondents were 959: 65% assigned female at birth (AFAB) and 35% assigned male at birth (AMAB). 91.8% and 8.2% were binary and non-binary TGD respondents, respectively. More than 20% of the TGD population reported to be unemployed with the highest rate detectable in AMAB and non-binary people. Cigarette smoking and binge drinking were higher in the TGD population compared with IGP (p < 0.05), affecting TGD subgroups differently. A significant lower percentage of AFAB TGD people reported having had screening for cervical and breast cancer in comparison with AFAB IGP (p < 0.0001, in both cases). Over 40% was the percentage of AFAB and non-binary TGD people accessing healthcare who felt discriminated against because of their gender identity. CONCLUSIONS: Our results are a first step towards a better understanding of the health needs of TGD people in Italy in order to plan the best policy choices for a more inclusive public health.

RESUMO

PURPOSE: Transition from pediatric to adult care is associated with significant challenges in patients with Turner syndrome (TS). The objective of the TRansition Age Management In Turner syndrome in Italy (TRAMITI) project was to improve the care provided to patients with TS by harnessing the knowledge and expertise of various Italian centers through a Delphi-like consensus process. METHODS: A panel of 15 physicians and 1 psychologist discussed 4 key domains: transition and referral, sexual and bone health and oncological risks, social and psychological aspects and systemic and metabolic disorders. RESULTS: A total of 41 consensus statements were drafted. The transition from pediatric to adult care is a critical period for patients with TS, necessitating tailored approaches and early disclosure of the diagnosis to promote self-reliance and healthcare autonomy. Fertility preservation and bone health strategies are recommended to mitigate long-term complications, and psychiatric evaluations are recommended to address the increased prevalence of anxiety and depression. The consensus also addresses the heightened risk of metabolic, cardiovascular and autoimmune disorders in patients with TS; regular screenings and interventions are advised to manage these conditions effectively. In addition, cardiac abnormalities, including aortic dissections, require regular monitoring and early surgical intervention if certain criteria are met. CONCLUSIONS: The TRAMITI consensus statement provides valuable insights and evidence-based recommendations to guide healthcare practitioners in delivering comprehensive and patient-centered care for patients with TS. By addressing the complex medical and psychosocial aspects of the condition, this consensus aims to enhance TS management and improve the overall well-being and long-term outcomes of these individuals.


The TRansition Age Management in Turner syndrome in Italy (TRAMITI) project aims to improve care for individuals with Turner Syndrome (TS) during their transition from pediatric to adult care. A team of 15 physicians and 1 psychologist collaborated to create a comprehensive set of 41 consensus statements, covering four key areas: transition and referral, sexual and bone health and oncological risks, social and psychological aspects and systemic and metabolic disorders. The consensus statements highlight the importance of patient-centered care, early intervention and long-term monitoring. They emphasize a multidisciplinary approach to address the complex medical and psychosocial aspects of TS. During the critical transition period, tailored approaches and early disclosure of the diagnosis are recommended to promote self-reliance and healthcare autonomy. To mitigate long-term complications, the consensus addresses fertility preservation and bone health strategies. It also recommends psychological or psychiatric evaluations to tackle the increased prevalence of anxiety and depression in patients with TS. In addition, strategies for addressing the heightened risk of metabolic, cardiovascular and autoimmune disorders in patients with TS are proposed. Regular screenings and interventions are advised to effectively manage these conditions. Furthermore, cardiac abnormalities, including aortic dissections, require close monitoring and early surgical intervention if specific criteria are met. Overall, the TRAMITI consensus statement provides valuable insights and evidence-based recommendations. It offers guidance for healthcare practitioners in delivering comprehensive and patient-centered care for individuals with TS. By addressing both medical and psychosocial aspects, the consensus aims to enhance TS management and improve the well-being and long-term outcomes of those affected by this genetic disorder.

RESUMO

PURPOSE: Gender Incongruence (GI) is a marked and persistent incongruence between an individual's experienced and the assigned gender at birth. In the recent years, there has been a considerable evolution and change in attitude as regards to gender nonconforming people. METHODS: According to the Italian Society of Gender, Identity and Health (SIGIS), the Italian Society of Andrology and Sexual Medicine (SIAMS) and the Italian Society of Endocrinology (SIE) rules, a team of experts on the topic has been nominated by a SIGIS-SIAMS-SIE Guideline Board on the basis of their recognized clinical and research expertise in the field, and coordinated by a senior author, has prepared this Position statement. Later on, the present manuscript has been submitted to the Journal of Endocrinological Investigation for the normal process of international peer reviewing after a first internal revision process made by the SIGIS-SIAMS-SIE Guideline Board. RESULTS: In the present document by the SIGIS-SIAMS-SIE group, we propose experts opinions concerning the psychological functioning, gender affirming hormonal treatment, safety concerns, emerging issues in transgender healthcare (sexual health, fertility issues, elderly trans people), and an Italian law overview aimed to improve gender non-conforming people care. CONCLUSION: In this Position statement, we propose experts opinions concerning the psychological functioning of transgender people, the gender-affirming hormonal treatment (full/partial masculinization in assigned female at birth trans people, full/partial feminization and de-masculinization in assigned male at birth trans people), the emerging issues in transgender health care aimed to improve patient care. We have also included an overview of Italian law about gender affirming surgery and registry rectification.

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

CONTEXT: The development of a safe and effective reversible method of male contraception is still an unmet need. OBJECTIVE: Evaluation of suppression of spermatogenesis and contraceptive protection by coadministered im injections of progestogen and testosterone. DESIGN: Prospective multicentre study. SETTING: Ten study centers. PARTICIPANTS: Healthy men, aged 18-45 years, and their 18- to 38-year-old female partners, both without known fertility problems. INTERVENTION: Intramuscular injections of 200-mg norethisterone enanthate combined with 1000-mg testosterone undecanoate, administered every 8 weeks. MAIN OUTCOMES MEASURES: Suppression of spermatogenesis by ejaculate analysis, contraceptive protection by pregnancy rate. RESULTS: Of the 320 participants, 95.9 of 100 continuing users (95% confidence interval [CI], 92.8-97.9) suppressed to a sperm concentration less than or equal to 1 million/mL within 24 weeks (Kaplan-Meier method). During the efficacy phase of up to 56 weeks, 4 pregnancies occurred among the partners of the 266 male participants, with the rate of 1.57 per 100 continuing users (95% CI, 0.59-4.14). The cumulative reversibility of suppression of spermatogenesis after 52 weeks of recovery was 94.8 per 100 continuing users (95% CI, 91.5-97.1). The most common adverse events were acne, injection site pain, increased libido, and mood disorders. Following the recommendation of an external safety review committee the recruitment and hormone injections were terminated early. CONCLUSIONS: The study regimen led to near-complete and reversible suppression of spermatogenesis. The contraceptive efficacy was relatively good compared with other reversible methods available for men. The frequencies of mild to moderate mood disorders were relatively high.

RESUMO

Administration of cross-sex hormones to male-to-female transsexual subjects, usually oestrogens + often anti-androgens, such as cyproterone acetate, carries a risk of venous thromboembolism (VTE). VTE usually occurs in the first year of oestrogen administration. Ethinyl oestradiol, due to its chemical structure, was in 2003 identified as a major factor in the occurrence of VTE. Most clinics do not prescribe ethinyl oestradiol any longer, but people who take hormones without medical supervision use often oral contraceptives containing ethinyl oestradiol, many times in overdose. Cessation of use of ethinyl oestradiol and peri-operative thrombosis prophylaxis for surgery have reduced prevalence rate of VTE. Other oral oestrogens should not be overdosed, and transdermal oestrogen is to be preferred. Thrombosis prophylaxis for surgery is mandatory. It seems advisable to stop hormone use at least 2 weeks before major surgery, to be resumed only after 3 weeks following full mobilisation.

RESUMO

To date, the effects of long-term testosterone (T) administration on the human vagina are not completely understood. Thus, the aim of this study was to investigate the effects of long-term T treatment on vaginal tissue histology, estrogen receptor alpha (ERα) and beta (ERß) expression and proliferation in female to male transsexual subjects (FtM). We compared vaginal samples from FtM subjects with those of premenopausal women (PrM) and postmenopausal women (M) not receiving any hormonal treatment for at least 2 years. Vaginal tissue samples from 16 FtM subjects treated with T (intramuscular injections of 100 mg Testoviron Depot/7-10 days for at least 1 year), undergoing sex reassignment surgery, and 16 PrM and 16 M subjects undergoing a vaginal hysterectomy for prolapse, were collected. For each sample, morphology, glycogen content, proliferation (ki-67), ERα and ERß expression were evaluated. Vaginal samples from FtM showed a loss of normal architecture of the epithelium, intermediate and superficial layers were completely lost, and glycogen content was depleted. T administration resulted in a strong proliferation reduction when compared with both M and PrM subjects. Stromal and epithelial ERα as well as ERß were significantly decreased in FtM when compared with PrM subjects. In conclusion, our data suggests that systemic T administration at supraphysiological dosage, determines profound changes in histomorphology and reduces ERs expression and proliferation of vaginal epithelium.

RESUMO

Recent data report an important role of testosterone (T) in modulating female sexual responses, but little is known about the expression and distribution of androgen receptor (AR) in the human vagina. Therefore, the aims of our study were to evaluate the expression of AR in the human vagina in premenopausal (PrM) and menopausal (M) women and in T-treated women. Vaginal biopsies were obtained from PrM and postmenopausal women and from women with gender identity disorder (female to male (FtM)) receiving exogenous T. AR gene and protein expression levels in vaginal tissues were determined by real-time PCR and western blot analysis, respectively, whereas the localization of AR in vaginal mucosa and stroma was performed by immunohistochemistry. ARs were detected by immunostaining both in the mucosa and stroma. In vaginal mucosa, AR density score decreases with age but does not change with T administration. In stromal tissue, AR density score does not change with age but significantly increases with T administration (P<0.01). AR protein expression was significantly increased in FtM subjects (P<0.001). The expression of AR messenger RNA (mRNA) evaluated by Real-time PCR showed a significantly higher mRNA expression in FtM versus M patients (P<0.01) and in PrM versus M subjects (P<0.05). In conclusion, we found AR protein and mRNA expression both in the epithelium and stroma of the human vagina in all groups of women. A negative correlation exists between age and AR expression in the vaginal mucosa. T administration increases AR expression in both the mucosa and stroma.

RESUMO

Childhood maltreatment (CM) is quite common and constitutes a nonspecific risk factor for a range of different psychiatric symptoms during lifespan. It has been demonstrated that sexual minorities are at higher risk of maltreatment and abuse, and a high proportion of transsexual subjects report CM. The aim of this study is to evaluate the prevalence of reported CM in a clinical sample of patients with male-to-female Gender Identity Disorder (MtF GID), and to explore the relationship between these early life events, body image and different psychopathological and clinical variables. A consecutive series of 162 patients with male genotype was evaluated from July 2008 to May 2010. A total of 109 subjects (mean age 36 ± 10 years) meeting the criteria for MtF GID and giving their informed consent were considered. The occurrence of CM experiences was evaluated through a face-to-face clinical interview. Patients were asked to complete the Body Uneasiness Test and Symptom Checklist-90 Revised. More than one-fourth of patients reported CM. Maltreated subjects reported a higher body dissatisfaction and display a worse lifetime mental health. The presence of reported CM in these patients has relevant psychopathological implications, and therefore should be carefully investigated.

RESUMO

Testosterone administered alone or in combination with progestogens in male contraception induces reversible oligo-azoospermia, but its effects on body composition and metabolism are less known. We analysed anthropometric and metabolic parameters in five groups of 10 males: four receiving testosterone undecanoate (TU: 1000 mg) plus norethisterone enanthate (NETE: 200 mg) at different intervals (every 8 weeks: NETE-8; every 12 weeks: NETE-12; every 6 weeks for 12 weeks and then every 12 weeks: NETE-6/12; every 6 weeks for 12 weeks and then TU plus placebo every 12 weeks: NETE-6/12/0) and one placebo (NETE-0/0) for a total of 48 weeks. Body mass index (BMI) and waist circumference did not change in any groups except for the NETE-8 in which BMI increased significantly (p = 0.02) at the end of the treatment period. Lean body mass (MAMC or AMA) increased significantly in the highest hormonal dose groups (p = 0.04, NETE-6/12; p = 0.004, NETE-8). No differences were observed in glucose levels, insulin sensitivity index and lipid profile as well as in biochemical and cell count parameters in any groups. In conclusion, NETE and TU for 48 weeks were not accompanied by any metabolic changes and any adverse effects. The weight gain of the highest NETE plus TU dosage was mainly because of gain in muscle mass.

RESUMO

The treatment of transsexual subjects is a challenging task for the endocrinologist who, in collaboration with the mental health professional and the surgeon, is called upon to confirm the diagnosis and adjust hormonal treatment aimed at suppressing endogenous sex hormones and to develop hormone characteristics of the desired gender. These guidelines are structured to provide evidence-based suggestions or, where evidence is lacking, expert recommendations on diagnostic procedures and hormonal treatment in adolescent and adult transsexuals, including long-term care and eligibility for surgery. The multidisciplinary approach to treatment, the additional diagnostic role of hormone administration and the need to maintain hormone levels within the physiological range are key suggestions stressed in the guidelines which are particularly important for an endocrinologist unfamiliar with this field. The need for psychological assessment before surgery is not common in many countries and should be stressed further in the guidelines. Some important issues such as time and method of hormone withdrawal before surgery together with when and which hormones should be administered after sex reassignment surgery has been completed also remain unclear. These guidelines represent a pivotal document for endocrinologists setting a standard for the care of transsexuals and providing directions for future research.

RESUMO

OBJECTIVE: To evaluate if cervical length predicts prepartum bleeding and emergency Cesarean section in cases of placenta previa. METHODS: Between September 2005 and September 2007, cervical length was measured by transvaginal ultrasound in women with complete placenta previa persisting into the third trimester of pregnancy. A complete follow-up of pregnancy was obtained in all cases. RESULTS: Overall, 59 women were included in the study group. The mean +/- SD gestational age at ultrasound was 30.7 +/- 2.7 weeks and the cervical length was 36.9 +/- 8.8 mm. Cesarean delivery was performed in all cases, at a mean gestational age of 34.7 +/- 2.3 weeks. Twenty-nine (49.1%) of the women presented prepartum bleeding and 12 (20.3%) required an emergency Cesarean section prior to 34 completed weeks due to massive hemorrhage. Cervical length did not differ significantly between cases with and those without prepartum bleeding (35.3 +/- 9.3 mm vs. 38.4 +/- 8.2 mm; P = 0.18), but was significantly shorter among patients who underwent emergency Cesarean section < 34 weeks due to massive hemorrhage compared with patients who underwent elective Cesarean section (29.4 +/- 5.7 mm vs. 38.8 +/- 8.5 mm; P = 0.0006). CONCLUSIONS: Transvaginal sonographic cervical length predicts the risk of emergency Cesarean section < 34 weeks in women with complete placenta previa.

RESUMO

BACKGROUND: This study was performed to assess spermatogenesis suppression and safety of a new combination of an etonogestrel (ENG) implant combined with testosterone undecanoate (TU) injections for male contraception. This is the first large placebo-controlled study for male hormonal contraception. DESIGN AND STUDY SUBJECTS: In this double-blind, multicenter study, we randomly assigned 354 healthy men to receive either a low- or high-release ENG implant sc combined with im TU injections (750 mg every 10 or 12 wk or 1000 mg every 12 wk) or placebo implant and injections. Treatment duration was 42 or 44 wk and posttreatment follow-up at least 24 wk. RESULTS: Overall, spermatogenesis was suppressed to 1 million/ml or less at wk 16 in 89% of men, with approximately 94% in two high-release ENG groups. Suppression was maintained up to the end of the treatment period in 91% of men. For all men who completed the treatment period, 3% never achieved 1 million/ml or less. Median recovery time to a sperm concentration above 20 million/ml was 15 wk (mean 17 wk, 95% confidence interval 16-18 wk). Treatment was well tolerated. As compared with the placebo group, more men in the active treatment groups reported adverse events such as weight gain, mood changes, acne, sweating, or libido change. For both spermatogenesis suppression and safety, differences were small between the active treatment groups. CONCLUSIONS: The combination of an ENG implant with TU injections is a well-tolerated male hormonal method, providing effective and reversible suppression of spermatogenesis. Although the results are good, there is still room for improvement, possibly by adjusting the dose regimen or changing the mode of application.

RESUMO

CONTEXT: Male hormonal contraceptive methods require effective suppression of sperm output. OBJECTIVE: The objective of the study was to define the covariables that influence the rate and extent of suppression of spermatogenesis to a level shown in previous World Health Organization-sponsored studies to be sufficient for contraceptive purposes (< or =1 million/ml). DESIGN: This was an integrated analysis of all published male hormonal contraceptive studies of at least 3 months' treatment duration. SETTING: Deidentified individual subject data were provided by investigators of 30 studies published between 1990 and 2006. PARTICIPANTS: A total of 1756 healthy men (by physical, blood, and semen exam) aged 18-51 yr of predominantly Caucasian (two thirds) or Asian (one third) descent were studied. This represents about 85% of all the published data. INTERVENTION(S): Men were treated with different preparations of testosterone, with or without various progestins. MAIN OUTCOME MEASURE: Semen analysis was the main measure. RESULTS: Progestin coadministration increased both the rate and extent of suppression. Caucasian men suppressed sperm output faster initially but ultimately to a less complete extent than did non-Caucasians. Younger age and lower initial blood testosterone or sperm concentration were also associated with faster suppression, but the independent effect sizes for age and baseline testicular function were relatively small. CONCLUSION: Male hormonal contraceptives can be practically applied to a wide range of men but require coadministration of an androgen with a second agent (i.e. progestin) for earlier and more complete suppression of sperm output. Whereas considerable progress has been made toward defining clinically effective combinations, further optimization of androgen-progestin treatment regimens is still required.

RESUMO

OBJECTIVE: To evaluate the feasibility of three-dimensional multiplanar sonography in the local staging of cervical carcinoma. METHODS: Between January 2005 and May 2006, 14 patients with invasive cervical carcinoma underwent transvaginal volume ultrasound examination prior to primary surgery. Parametrial invasion was evaluated in the coronal plane, while both bladder and rectal invasion were evaluated in the sagittal plane. Ultrasound findings were compared with surgical and histological results. RESULTS: In 12 of the 14 cases, three-dimensional ultrasound findings were compatible with pathology results. In the remaining two cases, either infiltration of right parametrium or rectal invasion were suspected at ultrasound but not confirmed at pathology. CONCLUSIONS: Despite the small number of patients evaluated, three-dimensional multiplanar sonography appears to be a promising technique in the local staging of cervical carcinoma.

RESUMO

Contraception is a crucial human right for its role on health, development and quality of life. Since the introduction of hormonal female contraception the burden of family planning has fallen mostly on women. The few methods of family planning available for men--namely condoms, vasectomy, periodic abstinence and withdrawal--are hundred year old in concept, are based on preindustrial practices and have low efficacy or are difficult to reverse. In spite of the shortcomings of currently available male contraceptives, 1/3 of the couples that use contraception worldwide rely on male methods suggesting that development of a safe, effective, reversible and affordable contraceptive method for men would meet a critical need. Recent surveys have shown that men want to know more about reproductive health and want to support their partner more actively. In recent decades, there have been exceptional advances in the development of safer and more effective contraceptives. Currently, several methods of contraception for men are under development. This paper summarises the efforts performed over the past decades to develop an effective, safe and reversible male contraceptive.
