RESUMEN
Maladaptive personality traits, such as 'dark personalities' are found to result in a diverse set of negative outcomes, including paraphilic interests and associated (illegal) behaviors. It is however unclear how these are exactly related, and if related, if then only those individuals higher on dark personality traits and higher impulsivity engage in paraphilic behaviors. In the current study, 50 participants were recruited to investigate the relationship between Dark Tetrad personality traits (i.e., narcissism, psychopathy, Machiavellianism and everyday sadism), paraphilic interests (arousal and behavior) and the moderating role of impulsivity. Personality and paraphilic interests were investigated through self-report questionnaires. Impulsivity was measured both through self-reported dysfunctional impulsivity and the P3 event related potential using electroencephalography during the Go/No-Go task (i.e. response inhibition). The results showed that there was a positive association between psychopathy, sadism and paraphilic interests. Whereas everyday sadism was associated with paraphilic (self-reported) arousal, psychopathy was associated with paraphilic behavior. Although P3 amplitude was not associated with paraphilic interests, self-reported dysfunctional impulsivity was associated with paraphilic behavior specifically. However, there was no moderating role of dysfunctional impulsivity and response inhibition (P3) in the relationship between psychopathy and paraphilic behavior. Findings indicate that the relation between specific dark personalities and paraphilic interests may be more complex than initially thought. Nevertheless, risk assessment and intervention approaches for paraphilia and related behavior both may benefit from incorporating Dark Tetrad and impulsivity measurements.

BACKGROUND: Accumulating evidence suggests that deficits in decision-making and judgment may be involved in several psychiatric disorders, including addiction. Behavioral addiction is a conceptually new psychiatric condition, raising a debate of what criteria define behavioral addiction, and several impulse control disorders are equivalently considered as types of behavioral addiction. In this preliminary study with a relatively small sample size, we investigated how decision-making and judgment were compromised in behavioral addiction to further characterize this psychiatric condition. METHOD: Healthy control subjects (n = 31) and patients with kleptomania and paraphilia as behavioral addictions (n = 16) were recruited. A battery of questionnaires for assessments of cognitive biases and economic decision-making were conducted, as was a psychological test for the assessment of the jumping-to-conclusions bias, using functional near-infrared spectroscopy recordings of prefrontal cortical (PFC) activity. RESULTS: Although behavioral addicts exhibited stronger cognitive biases than controls in the questionnaire, the difference was primarily due to lower intelligence in the patients. Behavioral addicts also exhibited higher risk taking and worse performance in economic decision-making, indicating compromised probability judgment, along with diminished PFC activity in the right hemisphere. CONCLUSION: Our study suggests that behavioral addiction may involve impairments of probability judgment associated with attenuated PFC activity, which consequently leads to higher risk taking in decision-making.

BACKGROUND AND AIMS: Compulsive Sexual Behavior Disorder (CSBD) is characterized by a persistent failure to control intense and recurrent sexual impulses, urges, and/or thoughts, resulting in repetitive sexual behavior that causes a marked impairment in important areas of functioning. Despite its recent inclusion in the forthcoming ICD-11, concerns regarding its assessment, diagnosis, prevalence or clinical characteristics remain. The purpose of this study was to identify participants displaying CSBD through a novel data-driven approach in two independent samples and outline their sociodemographic, sexual, and clinical profile. METHODS: Sample 1 included 1,581 university students (females = 56.9%; Mage = 20.58) whereas sample 2 comprised 1,318 community members (females = 43.6%; Mage = 32.37). First, we developed a new composite index to assess the whole range of CSBD symptoms based on three previously validated scales. Based on this new composite index, we subsequently identified individuals with CSBD through a cluster analytic approach. RESULTS: The estimated occurrence of CSBD was 10.12% in sample 1 and 7.81% in sample 2. Participants with CSBD were mostly heterosexual males, younger than respondents without CSBD, reported higher levels of sexual sensation seeking and erotophilia, an increased offline and especially online sexual activity, more depressive and anxious symptoms, and poorer self-esteem. CONCLUSIONS: This research provides further evidence on the occurrence of CSBD based on an alternative data-driven approach, as well as a detailed and nuanced description of the sociodemographic, sexual, and clinical profile of adults with this condition. Clinical implications derived from these findings are discussed in detail.

There is no accepted definition of the term paraphilia despite its being listed as an essential feature of a class of mental disorders known as the paraphilic disorders. The origin of the term, history of its inclusion as a diagnosis, and logical flaws inherent in the various definitions are discussed in this review. We examine the basis for pathologizing individuals with paraphilias, consider what paraphilias can tell us about how humans develop their sexual interests, and question the usefulness of dividing sexual interests into paraphilias and normophilias. The construct of the paraphilias appears to be poorly conceived and has outlived its usefulness.

AIM: To investigate serotonin and catecholamine levels in people with paraphilic disorders and identify correlations between transmitter dysfunction and clinical signs of paraphilic disorders. MATERIAL AND METHODS: Fifteen men with paraphilic disorders were studied using clinical-psychopathological, sexological, biochemical and statistical methods. RESULTS: There were an increase in the levels of serotonin and norepinephrine and a decrease in the concentration of DOPAC (3,4-dihydroxyphenylacetic acid) in the urine of patients with paraphilic disorders. The concentrations of serotonin and norepinephrine are correlated with obsessive disturbances. The level of DOPAC was associated with affective and dissociative disorders. CONCLUSION: The relationships between biochemical and psychopathological signs suggest a role of biological mechanisms in the organization of abnormal sexual behavior. Correlations between psychopathological phenomena and DOPAC indicate a key role of central dopamine in the pathogenesis of paraphilic disorders and disturbances of conscious regulation of behavior.

This study examined qualitative data on 1,795 male, 139 female, and 78 transgender members of the adult baby/diaper lover (ABDL) online community. Using grounded theory, the analyses examined a description of ABDL practices, explored evidence of subgroups within the ABDL community, and examined the degree to which ABDL behavior involves sexual motivations. Overall, the data suggest there is a fair amount of diversity within the ABDL community. Most participants enjoy wearing diapers or engaging in age regression (as babies or children), and the importance of incontinence may vary. ABDL practices can reflect bondage play for some individuals and a way to cope with medical problems for others. Overall, there is modest evidence of more than two ABDL subgroups. Although a large number of individuals do not see their ABDL practices as sexual in nature, there is a clear contingent that describes sexual motivations. For some, sex during ABDL activity violates conceptions of baby play. Nonsexual motivations include a desire to relax or be carefree as well as a desire to be nurtured. Some diaper lovers and adult babies have the same goals but achieve them in different ways. ABDL practices may be as diverse as seemingly typical sexual behaviors.

PURPOSE OF REVIEW: This paper reviews recent research into four different approaches to the assessment of offense-related sexual deviance. RECENT FINDINGS: Two of these approaches, structured rating scales and phallometry, have a sufficient basis in research for clinical use but have undergone significant refinements in recent years. One approach, the use of cognitive tasks to indirectly assess sexual deviance, is approaching the point where it has a sound research basis for clinical use though too many promising tasks have yet to make the transition from laboratory to clinical practice. This approach has however begun to map the earlier stages of sexual response including preconscious processes. The final approach, assessment through neuroimaging, is at the earliest stage of development with research findings having yet to reach sufficient stability for clinical application. Existing assessment technologies, despite their limitations, allow professionals to assess offense-related sexual deviance. New approaches, currently being developed, potentially allow a better understanding of underlying processes and, when sufficiently mature, will be more therapeutically useful.

OBJECTIVE: Zoophilia is a rare paraphilic disorder with intense sexual urges involving animals. Autism is characterised by impairments in social communication and repetitive, restricted behaviours (RRB). Reported cases of zoophilia are limited worldwide, and zoophilia in autism is rarer. METHOD: This is a case report describing this unique and relatively unrecognised association in a male adolescent from Sri Lanka. RESULTS: A 17-year-old boy diagnosed with autism has average intelligence and academic capabilities. He had spent increasing time at his grandparents' cattle house. First, he was found masturbating near the cows and later having penetrative intercourse with a heifer. The shocked parents first sought traditional healing in the form of 'thovil', a demonic ritual of exorcist nature. Later, clinical evaluation found intense sexual urges towards cattle, which had led to marked distress and academic impairment. Sex hormone profile was normal. The adolescent was treated with a combination of cognitive-behaviour therapy and a selective serotonin reuptake inhibitor. CONCLUSION: We postulate that his persistent social difficulties contributed to the development of a paraphilic disorder. Unlike with his RRBs, he was markedly distressed about this sexual behaviour. Further research is required to explore this rarely reported, potential association.

To date there are few treatment options to reduce high sexual drive or sexual urges in paraphilic patients with a risk for sexual offending. Pharmacological therapy aims to reduce sexual drive by lowering testosterone at the cost of severe side effects. We hypothesize that high sexual drive could also be reduced with deep brain stimulation (DBS) of circuits that generate sexual drive. This approach would help to avoid systemic side effects of antiandrogenic drug therapies. So far the best investigated target to reduce sexual drive is the ventromedial hypothalamus, which was lesioned unilaterally and bilaterally by stereotaxic interventions in paraphilic patients in the 1970s. Here, we discuss DBS as a treatment strategy in patients with severe paraphilic disorders with a serious risk of sexual offending. There are profound ethical and practical issues associated with DBS treatment of paraphilic patients that must be solved before considering such a treatment approach.

Antisaccade task performance and mean amplitudes of slow cortical potentials (contingent negative variation--CNV) were investigated in 19 healthy volunteers, 16 schizophrenic patients (SP), and 12 patients with stereotyped form of paraphilia (PP). Compared with healthy subjects, schizophrenic and paraphilic patients committed significantly more erroneous saccades. The clear between-group CNV differences were observed during the early CNV stage that is associated with cognitive aspects of preparatory set. In SP, as compared to controls, the significant decline of CNV amplitude was found at frontal-central area. PP have demonstrated the lack of CNV over central and parietal regions, but their CNV amplitudes in frontal area did not differ from values of control group. Thus, two distinct types of CNV abnormalities have been found. The SP results have been interpreted as support for frontal dysfunction in schizophrenia. The disconnection between prefrontal cortex, sensorimotor cortex, and related subcortical structures is hypothesized in paraphilia group.

Las parafilias son entidades patológicas de la esfera psiquiátrica que difieren de otros comportamientos sexuales por las serias implicaciones que suponen en la vida de los pacientes. Las urofilias son parafilias que implican al ámbito urológico. Estas presentan un amplio espectro de variaciones clínicas, llegando a poder tener serias consecuencias para la vida. La introducción de objetos en la uretra o en la vejiga es la urofilia que más frecuentemente requiere asistencia médica, ya sea por daño en la vía urinaria o por las implicaciones de alojar cuerpos extraños en ella. A raíz de la identificación de un insólito cuerpo extraño en la vejiga se ha realizado una revisión del tema desde la vertiente psiquiátrica y urológica de esta patología (AU)
Paraphilias are pathologies of the psychiatric field that differ from other sexual behavior because of the serious implications in the lives of the patients. Urophilias are paraphilias involving the urological setting. They have a wide spectrum of clinical variations and can have serious consequences for life. Insertion of objects into the urethra or bladder is the urophilia that most frequently requires medical care, either by damage to the urinary tract or due to the implications of hosting foreign bodies in it. Following the identification of an unusual foreign body in the bladder, a review of the subject from the psychiatric and urological side has been carried out (AU)

INTRODUCTION: Antiandrogen therapy has been used for 30 years to treat paraphilic patients and sexual offenders. Yet the therapeutic success of antiandrogens is uncertain. Furthermore, there is still a lack of comprehensive knowledge about the effects of androgen-lowering therapy in paraphilic patients. AIM: We discuss endocrinological, neurobiological, and therapeutic aspects of paraphilia with the aim of integrating these on the basis of the current neurobiological and clinical knowledge on testosterone that was set out in Part I of this review. METHODS: Our review of the human literature comprises the current knowledge about the neurobiology of paraphilia and the known endocrinological, pathophysiological, and genetic aspects of this disorder. The role of testosterone is discussed. A survey of antiandrogen therapy and its outcome in paraphilic patients and sex offenders is provided. RESULTS: Although not all data are consistent, current imaging research suggests that structural and functional changes in pedophilia appear for the most part in brain regions also involved in sexual functions. Not exclusively testosterone but also some other endocrinological and neurochemical parameters could be disturbed in pedophilic patients and child molesters; these include changes in hypothalamic-pituitary function, prolactin levels, and dopaminergic or serotonergic functions. There appears to be a sex-steroid-related genetic influence on antisocial traits, externalizing behavior, and sexual behavior. Most of the studies in which antiandrogen therapy in paraphilic patients and sex offenders have been examined were case reports, or observational or open-label studies, and many did not include adequate control groups. Only a few placebo-controlled double-blind studies have been published with inconsistent results concerning treatment effects. Outcome measures differ between the studies and do not seem ideally suited to their purpose. CONCLUSIONS: On the basis of the current knowledge about testosterone and its effects on brain and behavior as described in Part I, and of available results on the relationship between testosterone and paraphilia as well as antiandrogen therapy, we present from a neurobiological perspective an extended scientific proposal for design features to investigate the effects of antiandrogen treatment in large clinical trials.

INTRODUCTION: As Parkinson's disease progresses, its non-motor manifestations become increasingly more apparent to the point where, in advances phases of the disease, they are the most important clinical symptoms. A very wide range of non-motor symptoms can appear in Parkinson's disease. Impairment of the urinary function and the sexual function (understood as the capacity to carry out sexual activity) can be seen as belonging to the dysautonomic disorders. Hypersexuality would be included within the group of impulse control disorders. DEVELOPMENT: This study reviews the epidemiology, phenomenology and treatment of urinary disorders, sexual dysfunction and hypersexuality as non-motor symptoms of Parkinson's disease. CONCLUSIONS: Urinary disorders are the most frequent non-motor symptom in Parkinson's disease. They usually present as nocturia, urgency and increased mictional frequency (pollakiuria). Preferred treatment is with anticholinergic agents. Sexual dysfunction is a frequent complaint in patients with Parkinson. It has a multifactorial aetiology and is more frequent in males than in females. In males it manifests mainly as incapacity to achieve an erection, premature ejaculation or loss of the capacity to ejaculate, whereas in females the predominant signs are decreased libido, lowered arousal and difficulty in reaching an orgasm. Hypersexuality affects young males above all and has been related to the use of dopamine agonists.

There is a proposal to establish a paraphilic coercive disorder as a new paraphilia in the DSM-V. The empirical data do not, however, support the hypothesis that a distinct syndrome exists that comprises males who are sexually aroused by the coercive elements of rape per se. Purported evidence for this syndrome has centered on the results of phallometric studies. Higher plethysmographic responses of rapists to coercive rape scenarios may, however, be better explained by the failure of coercive elements to inhibit arousal to sexual aspects of the stimuli rather than by arousal specifically to the coercive elements. In addition, sexual fantasies about forcing sex and about struggling victims are highly correlated with sadistic fantasies and have not been shown to identify a syndrome that can be discriminated from sadism. Finally, taxometric evidence strongly supports the hypothesis that the underlying components of rape are distributed as dimensions and do not constitute a separate taxon. Consequently, the criteria purported to categorize rapists into the proposed syndrome would have to be arbitrarily determined. Not only does there seem to be little empirical justification for the creation of this new syndrome, the inclusion of this disorder among the paraphilias would have serious potential for misuse. It would imply endorsement of Paraphilia, NOS, nonconsent, which is currently inappropriately employed in civil commitment proceedings to justify commitment.

Although sex offender risk assessment has progressed greatly over the past decade and a half since most states implemented the sexually violent predator/sexually dangerous person (SVP/SDP) laws, there continues to be limited applicability of such models to intellectually disabled sex offenders because there has been no empirical validation. However, SVP/SDP civil commitment programs have reported increased admission of developmentally disabled sex offenders. Differentiating sexual deviance, the primary factor predisposing most individuals to criminal sexual violence, from impulsive, immature, and inappropriate behavior stemming from cognitive deficits presents yet another challenge to the clinician tasked with performing such evaluations. This article reviews actuarial risk models and their limited applicability to mentally retarded sex offenders and offers a conceptual method of assessing the risk of recidivism in intellectually disabled sex offenders under SVP/SDP evaluation.

Previous studies have identified sexual deviance as a particularly strong predictor of sexual recidivism in sex offenders. The present study examined the construct validity (i.e., convergent and discriminant validity) of the three dynamic factor domains (Sexual Deviance, Criminality, Treatment Responsivity) of the Violence Risk Scale- Sexual Offender version (VRS-SO) as well as the Screening Scale for Pedophilic Interests (SSPI; for comparison purposes) with respect to phallometric measures of sexual deviance. VRS-SO and phallometric data were collected from 124 federally incarcerated sex offenders from a maximum security forensic psychiatric facility. The Sexual Deviance factor and SSPI were positively correlated to varying degrees with computed arousal indexes (Percent Full Erection, difference scores) for child stimuli but were not significantly correlated with nondeviant arousal, supporting the convergent and discriminant validity of these measures, respectively. Convergent validity also appeared stronger for sex offender subtypes with child victims. Criminality and Treatment Responsivity did not correlate with male stimuli, although they were positively correlated with arousal to female profiles. The VRS-SO Sexual Deviance factor and some phallometric indexes of deviant arousal (e.g., female children) were predictive of sexual recidivism whereas the SSPI was not. The pattern of findings across analyses broadly supports the construct validity of the VRS-SO in assessing sexual deviance.

Apotemnophilia straddles the boundary between neurology and psychiatry. It is a condition in which individuals experience the strong and specific desire for amputation of a healthy limb. Research suggests this disorder may be of neurological origin, specifically that the body image centers of the brain lack a cortical representation for a particular limb. A curious aspect of this condition is that sufferers often report an attraction to amputees in addition to desiring their own limb be removed. We postulate that sexual 'aesthetic preference' for certain body morphology is dictated in all individuals in part by the cortical representation of one's body image.

A unique challenge posed by advancing scientific knowledge about the biology of human behavior is how to integrate that understanding with the desire to hold ourselves--and one another--morally accountable. As human beings, we are something more than just passive agents whose behavior is the sum product of biologic determinism. Because of the existence of the mind, we are also active agents with the capacity to influence, at least to some extent, our own destinies. Behavior may be determined, but it is not predetermined. We are one of its determinants. Misconduct by a person of sound mind should not be attributed improperly to brain pathology. On the other hand, suffering, legitimate mental disorder, and associated impairments should not be trivialized. Historically, persons who once were labeled "lazy" are often more appropriately understood by modern standards as clinically depressed. Frequently they are more in need of pharmacologic treatments that alter brain chemistry than "a kick in the behind." Gluttony, one of the original cardinal sins, is often more properly understood as morbid obesity, a condition that deserves appropriate medical care. Persons who have alcoholism, once judged morally as "bums in the gutter," are more frequently referred to treatment facilities, such as The Betty Ford Clinic. One should not approach the issue of human sexual behavior without at least some appreciation of moral values and scientific research. Although clearly some persons choose to act in a sexually selfish and self-indulgent fashion with wanton disregard, others seem to be more genuinely burdened and struggle to integrate their sexual desires into an otherwise healthy and fully responsible lifestyle. When a person, whether male or female, seems to be so driven that it becomes difficult to master erotic desires and he or she experiences difficulty serving his or her own best longterm interests, the concept of sexual compulsivity seems to be relevant. Ultimately, a better understanding of any associated neuropathologies may help to facilitate future treatments and public acceptance. The possibility exists, at least in some instances, that a sexually compulsive individual is less an example of a bad person deserving of punishment than a "broken mind" in need of repair. In time, increased knowledge about the precise workings of the brain in reciprocally initiating and sustaining the sexual interests of the mind may facilitate a much clearer appreciation of the issues at hand.

O abuso sexual na infância é definido com a situação em que a criança ou o adolescente é usado para satisfação sexual de um adulto ou adolescente mais velho, sendo a violência sempre presumida em menores de 14 anos. É um fenômeno universal que atinge todas as idades, classes sociais, etnias, religiões e culturas e pode ser considerado como qualquer ato ou conduta baseado no gênero, que cause dano ou sofrimento psíquico e sexual à vítima. No Brasil, a violência contra crianças e adolescentes é a primeira causa de morte na faixa etária de cinco a 19 anos e a segunda no período de um a quatro anos. Médicos pediatras e ginecologistas devem ser alertados e capacitados para lidar com questões ligadas ao abuso, tornando-se aptos a atuarem de maneira adequada. A questão do abuso sexual, por ter uma complexidade de fatores envolvidos, não pode ser explicada de forma reducionista ou determinista, devendo assim, ser valorizada a presença de uma equipe interdisciplinar no atendimento a esses pacientes. Neste estudo foi realizada uma revisão bibliográfica sobre o abuso sexual e suas repercussões.
Sexual abuse of children is defined as a situation in which a child or an adolescent is used for the sexual satisfaction of an adult or older adolescent with violence always being presumed for children younger than 14 years. This is a universal phenomenon that involves all ages, social classes, ethnic groups, religions and cultures and that can be considered as any act or conduct based on gender that will cause damage or psychic and sexual suffering to the victim. In Brazil, violence against children and adolescents is the first cause of death in the age range from five to nineteen years and the second in the age range from one to four years. Pediatricians and gynecologists should be alerted and prepared to deal with questions related to abuse, so that they may be qualified to act in adequate manner. Because of the complexity of the factors involved, the question of sexual abuse cannot be explained in a reductionist or deterministic manner. Thus, emphasis should be placed on the presence of an interdisciplinary team to take care of these patients. A review of the literature on sexual abuse and its repercussions was performed in the present study.
