From a case report of a person with pedophilic disorder, this paper focuses on the issue of pedophilia, child sexual abuse, and the need for specific prevention and treatment strategies in Brazil. It seems inevitable to increase awareness for this topic within the mental health care system to protect children and reduce the risk for sexual offense in individuals at-risk. This is a case report of an individual, known by medical-psychiatric and forensic facilities for a past history of patricide, who revealed his pedophilic fantasies and behavior belatedly.

Background: We systematically reviewed the literature and performed a meta-analysis on the effects of speech therapy and phonosurgery, for transgender women, in relation to the fundamental frequency gain of the voice, regarding the type of vocal sample collected, and we compared the effectiveness of the treatments. In addition, the study design, year, country, types of techniques used, total therapy time, and vocal assessment protocols were analyzed.

Methods: We searched the PubMed, Lilacs, and SciELO databases for observational studies and clinical trials, published in English, Portuguese, or Spanish, between January 2010 and January 2023.

For transgender individuals, gender-affirming surgery (GAS) and cross-sex hormone therapy (CSHT) are part of the gender transition process. Scientific evidence supporting the maintenance of CSHT after GAS-related gonadectomy is accumulating. However, few data are available on the impact of CSHT on the brain structure following hypogonadism.

An extreme incongruence between sex and gender identity leads individuals with gender dysphoria (GD) to seek cross-sex hormone therapy (CSHT), and gender-affirming surgery (GAS). Although few studies have investigated the effects of CSHT on the brain prior to GAS, no studies in the extant literature have evaluated its impact during hypogonadism in post-GAS individuals. Here, we aimed to evaluate the effects of estradiol on resting-state functional connectivity (rs-FC) of the sensorimotor cortex (SMC) and basal ganglia following surgical hypogonadism.

The present study assessed the prevalence of sexually transmitted infections (STIs) in 90 transsexual men (female-to-male transsexual persons) from southern Brazil. A retrospective review of the medical records of all transsexual men who visited an outpatient clinic in Rio Grande do Sul from 1998 to 2017 was performed. Although the sample had a high prevalence of risk factors for contracting STIs, such as drug use, one-third of the participants had never been tested for STIs and, when screened, it was mostly for HIV, but not for syphilis or other STIs.

Gender dysphoria (GD) (DMS-5) is a condition marked by increasing psychological suffering that accompanies the incongruence between one's experienced or expressed gender and one's assigned gender. Manifestation of GD can be seen early on during childhood and adolescence. During this period, the development of undesirable sexual characteristics marks an acute suffering of being opposite to the sex of birth.

Voice is an important gender marker in the transition process as a transgender individual accepts a new gender identity. The objectives of this study were to describe and relate aspects of a perceptual-auditory analysis and the fundamental frequency (F0) of male-to-female (MtF) transsexual individuals. A case-control study was carried out with individuals aged 19-52 years who attended the Gender Identity Program of the Hospital de Clínicas of Porto Alegre.

Introduction:: Transsexualism (ICD-10) is a condition characterized by a strong and persistent dissociation with one's assigned gender. Sex reassignment surgery (SRS) and hormone therapy provide a means of allowing transsexual individuals to feel more congruent with their gender and have played a major role in treatment over the past 70 years. Brain-derived neurotrophic factor (BDNF) appears to play a key role in recovery from acute surgical trauma and environmentally mediated vulnerability to psychopathology.

Dysfunctional cognitions may be associated with unhealthy eating behaviors seen in individuals with obesity. However, dysfunctional cognitions commonly occur in individuals with poor mental health independently of weight. We examined whether individuals with morbid obesity differed with regard to dysfunctional cognitions when compared to individuals of normal weight, when mental health status was controlled for.

A history of childhood maltreatment (HCM) has been associated with detrimental psychiatric outcomes. This is particularly true for transgender, for whom there is initial evidence that HCM may be associated with psychiatric morbidity. Our study aimed to further characterize the relationship between HCM and the development of mental disorder in adult life, based on a sample of Brazilian transgender women.

Previous research has indicated that biological older brothers increase the odds of androphilia in males. This finding has been termed the fraternal birth order effect. The maternal immune hypothesis suggests that this effect reflects the progressive immunization of some mothers to male-specific antigens involved in fetal male brain masculinization.

Serum BDNF levels are significantly decreased in transsexual Brazilian women when compared to cis-sexual men. Since transsexual men are also exposed to chronic social stress and have a high prevalence of associated psychopathologies, it is plausible to inquire if BDNF serum levels are altered in transsexual men as well. Therefore, our objective was to evaluate differences in BDNF serum level of transsexual men when compared to cis-sexual men and women.

Objectives: The aim of the study was to verify the answers to the transsexual voice questionnaire for male-to-female transsexual (TVQ) people given to individuals who participated in the Gender Identity Program (PROTIG) at the Hospital de Clínicas de Porto Alegre, Brazil, in relation to some of their demographic characteristics, visual-perceptual evaluations of the face, laryngeal prominence, and auditoryperceptual judgments of voice.

Methods: In this cross-sectional study, 47 transsexual women aged between 18 and 50 responded to the (TVQ). The demographic data and perceptual ratings were selected from the PROTIG database.

Gender dysphoria (GD) (DSM-5) or transsexualism (ICD-10) refers to the marked incongruity between the experience of one's gender and the sex at birth. In this case report, we describe the use of LSD as a triggering factor of confusion in the gender identity of a 39-year-old male patient, with symptoms of psychosis and 25 years of substance abuse, who sought psychiatric care with the desire to undergo sex reassignment surgery. The symptoms of GD/psychosis were resolved by two therapeutic measures: withdrawal of psychoactive substances and use of a low-dose antipsychotic.
