BACKGROUND: Adolescent compulsive sexual behavior (CSB), and its associations with other personality predispositions (attachment orientations, temperament), gender, religiosity, and psychopathological tendencies. Five alternative empirical models were examined, all based on current theory and research on CSB. METHODS: The sample include 311 high-school adolescents (184 boys, 127 girls) ranging in age from 16 to 18 (M  = 16.94, SD  = .65) and enrolled in the eleventh (43...

The aim of this study was to evaluate the role of childhood adversities in long-term outcomes in eating disorders (EDs). One hundred thirty-three eating disorder patients were studied by means of the Structured Clinical Interview for DSM-IV and psychometric tests, at baseline, at the end of individual cognitive behavioural therapy, and at 3-year follow-up. As compared with the other patients, those reporting childhood abuse (overall: 24.8%; physical abuse: 20.3%; sexual abuse: 13.6%) showed higher impulsivity, psychiatric comorbidity, lower full recovery at follow-up (12...

Early life trauma (ELT) may increase the risk towards bipolar disorder (BD) and major depression (MDD), disorders associated with activated neuro-oxidative and neuro-nitrosative stress (O&NS) pathways. It has remained elusive whether ELTs are associated with O&NS and which ELTs are associated with distinct affective disorder phenotypes. This case-control study examined patients with BD (n = 68) and MDD (n = 37) and healthy controls (n = 66). The Child Trauma Questionnaire (CTQ) was used to assess specific ELT...

Background: The male predominance in the prevalence of autism spectrum disorder (ASD) has motivated research on sex differentiation in ASD. Multiple sources of evidence have suggested a neurophenotypic convergence of ASD-related characteristics and typical sex differences. Two existing, albeit competing, models provide predictions on such neurophenotypic convergence. These two models are testable with neuroimaging. Specifically, the Extreme Male Brain (EMB) model predicts that ASD is associated with enhanced brain maleness in both males and females with ASD (i...

Addiction is the term employed not only for excess consumption of substances, but also for problem behaviours like eating disorders, pathological gambling, computer addiction and pathological preoccupation with video games and sexual acts. No clear diagnostic criterion has been established with validity for behavioral addictions. Sexual addiction, including addiction to pornography is not included as a separate entity because of a lack of strong empirical evidence in this area. Different scales can be used for assessment of sexual addiction...

Substance abuse and addictive disorders are very common in the community. Patients with addictive disorders frequently experience sexual dysfunctions and chronic use of substances tends to adversely affect all stages of sexual response, in both male and female abusers. An important aspect in the management of sexual dysfunction is psychosocial intervention. In addictive disorders, sexual dysfunction is of high clinical relevance, as it often leads to treatment non adherence and sexual or marital disharmony...

While guidelines for psychosocial interventions in addictive disorders in India were earlier rooted in clinical experience and global empirical evidence, recently there have been efforts to develop guidelines for intervention based on the local needs assessments of specific populations and more appreciably, a testing of the effectiveness of the interventions. This supplement on psychosocial interventions for addictive disorders covers some of the important aspects of psychosocial interventions in five sections...

Cancer itself and its treatments can result in physical and/or psychological adverse events which include disorders of sexual health. Both clinicians and patients are reluctant to talk about sexual issues, body image or intimacy between partners. Barriers from the clinician's perspective include feeling inadequately trained, lack of time or privacy. On the patients' side, embarrassment or belief that their sexual health are an untreatable complication of their disease and its treatment are the main barriers...

Patients with rectal cancer have an increased risk of developing sexual disorders. These dysfunctions are caused by the disease itself (negative psychological impact, nerve compression in the pelvis), as well as by the treatments (radiotherapy, chemotherapy and surgery). Most sexual disorders are due to the surgery and can be attributed to injuries of the retroperitoneal nerves. Sexuality assessment of patients before and after treatment, a precise knowledge of the pelvic anatomy by the surgeon, and an appropriate care by specialists (gynaecologists, urologists and sexologists) are essential to reduce the risk of sexual disorders and to minimize their impact on overall quality of life...

INTRODUCTION: Among gay, bisexual, and other men who have sex with men (GBM), collinearity between polysubstance use and mental health concerns has obscured their combined effects on HIV risk with multivariable results often highlighting only one or the other. METHODS: We used mediation and moderation analyses to examine the effects of polysubstance use and depressive symptoms on high-risk sex (i.e., condomless anal sex with serodiscordant/unknown status partner) in a sample of sexually-active GBM, aged ≥16 years, recruited in Metro Vancouver using respondent driven sampling...

INTRODUCTION: Erotic asphyxiation is a sexual phenomenon in which one partner reduces the other person's brain oxygen level through strangulation. This study analyzes deaths caused by sexually-motivated strangulation to cases of homicidal choking - summarizing criminal penalties for defendants, depending on the presence of drugs, or alcohol intoxication. METHODS: The mode of analysis involves three sources of data. First, a retrospective chart review of our clinics' two recent cases...

OBJECTIVES: To determine if differing developmental factors show specificity to differing manifestations of borderline personality disorder (BPD). METHODS: A clinical sample of 73 females diagnosed with BPD undertook a psychiatrist interview and completed self-report questionnaires, including the semi-structured Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV) assessing for BPD status. A set of negative and potentially traumatic developmental factors were included in the assessment...

Infertility affects up to 12% of all men, and sexual dysfunction occurs frequently in men of reproductive age, causing infertility in some instances. In infertile men, hypoactive sexual desire and lack of sexual satisfaction are the most prevalent types of sexual dysfunction, ranging from 8.9% to 68.7%. Erectile dysfunction and/or premature ejaculation, evaluated with validated tools, have a prevalence of one in six infertile men, and orgasmic dysfunction has a prevalence of one in ten infertile men. In addition, infertile men can experience a heavy psychological burden...

Transcriptional control of oxytocinergic cell development influences social, sexual, and appetite related behaviors, and is implicated in disorders such as autism and Prader-Willi syndrome. Mediator 12 (Med12) is a transcriptional coactivator required for multiple facets of brain development including subsets of serotonergic and dopaminergic neurons. We surveyed hormone gene expression within the hypothalamo-pituitary axis of med12 mutant zebrafish embryos with a focus on oxytocin ( oxt ) expression. Some transcripts, such as oxt , vasopressin ( avp ) and corticotrophin releasing hormone ( crh ) are undetectable in the med12 mutant, while others are upregulated or downregulated to varying degrees...

BACKGROUND: We aimed to complete a nationally representative study of sexual violence against children in South Africa, and its correlates, since we could identify no other such study. METHODS: For this nationally representative, cross-sectional study in South Africa, households were selected by use of a multistage sampling frame, stratified by province, urban or rural setting, and race group, and schools were selected on the basis that they were closest to the area in which households were selected...

BACKGROUND: Glycans are short chains of saccharides linked to glycoproteins that are known to be involved in a wide range of inflammatory processes. As depression has been consistently associated with chronic low-grade inflammation, we asked whether patients with Major Depressive Disorder show alterations in the N-glycosylation pattern of serum proteins that might be linked to associated changes in inflammatory processes. METHODS: In a study cohort of 21 female patients with an acute depressive episode and 21 non-depressed female control subjects aged between 50 and 69 years, we analyzed the serum N-glycan profile by DNA Sequencer Adapted-Fluorophore Assisted Carbohydrate Electrophoresis (DSA-FACE) and assessed the serum levels of interleukin (IL)- 6, tumor necrosis factor (TNF)-α and C-reactive protein (CRP) by chemiluminescence immunoassays and nephelometry...

As youth with perinatally acquired HIV infection age, there is a need for studies that identify predictors and correlates of sexual risk behaviors. We examined the association between psychiatric disorders and substance use disorders (SUD) with sexual risk behaviors in youth with perinatally acquired HIV infection and perinatally HIV-exposed but uninfected youth. Participants were recruited from four medical centers in New York City. The Diagnostic Interview Schedule for Children and the Adolescent Sexual Behavior Assessment were administered to assess psychiatric disorders and sexual behaviors, respectively...

Sleep apnea is a common sleep disorder characterized by intermittent periods of low blood oxygen levels. The risk for sleep apnea increases with age and is more prevalent in men than women. A common comorbidity of sleep apnea includes male sexual dysfunction, but it is not clear if a causal relationship exists between sleep apnea and sexual dysfunction. Possible mechanisms that link these two disorders include oxidative stress and testosterone. Oxidative stress is elevated in clinical patients with sleep apnea and in rodents exposed to chronic intermittent hypoxia (CIH), an animal model for apnea-induced hypopnea...

BACKGROUND: Stressful life events and maltreatment have traditionally been considered crucial in the development of conversion (functional neurological) disorder, but the evidence underpinning this association is not clear. We aimed to assess the association between stressors and functional neurological disorder. METHODS: We systematically reviewed controlled studies reporting stressors occurring in childhood or adulthood, such as stressful life events and maltreatment (including sexual, physical abuse, and emotional neglect) and functional neurological disorder...
