Purpose: Klinefelter's syndrome (KS) is associated with specific neurobehavioral features and personality traits. The aim of our study was to investigate fluid intelligence, personality traits and personality disorders (PD) and possible correlations with testosterone in a cohort of adult KS patients., Methods: We analyzed 58 adult KS patients with the classic 47, XXY karyotype. The Structured Clinical Interview for axis II disorders was used to assess DSM IV personality disorders. Personality traits were assessed using MMPI-2. Fluid intelligence was tested by using Raven's Standard Progressive Matrices (SPM) Test. Testosterone blood concentration was measured by CMIA., Results: PD prevalence was 31%. Four altered MMPI scales (Social Responsibility, Dominance, Ego Strength and Repression) were found in more than 40% of patients. Overcontrolled hostility and MacAndrew Alcoholism Scale-Revised scales were altered in the PD- group only. Biz-Odd Thinking and Post-Traumatic Stress Disorder scale were associated with the presence of personality disorder. The raw SPM score was 44 ± 10.8 without any significant correlation with testosterone. No significant difference in mean age, SPM raw score and MMPI score was observed between eugonadal, hypogonadal and treated patients., Conclusions: Most KS patients had average fluid intelligence. PD prevalence was higher than in the general population. Testosterone was not correlated with fluid intelligence, personality traits or PD, but a reduction in marital distress was observed in treated patients. This could suggest that testosterone therapy can improve physical symptoms and this effect could also improve relationship abilities and wellness awareness.

Background and Aims: Psychiatric disorders are common in obese patients and they are often considered contraindications for bariatric surgery. In this patients Axis I profile has been widely investigated, while only few studies on Axis II profile are reported. Aim of the study was to examine the prevalence of Axis II psychopathology, to describe the typical body image and to evaluate the prevalence of childhood abuse in bariatric surgery candidates., Materials and Methods: A total of 102 consecutive obese patients (77 females) were evaluated by the Structured Clinical Interview for DSM IV which assessed Axis I Disorders. After the exclusion of Axis I Disorders, 50 patients (36 females, BMI: 44.68 ± 9.48 Kg/m2, age: 44.5 ± 11.7 years) were enrolled. All 50 patients received a psychiatric assessment including the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II); the Body Uneasiness Test, part a (BUT-A), which assesses body image disorders; the Childhood Trauma Questionnaire (CTQ) as a screening test of childhood maltreatment histories., Results: Nineteen patients (38%) were affected by Axis II disorders. Cluster C disorders, including avoidant, dependent and obsessive-compulsive personality disorders, represented the most common diagnosis (24%). Moreover, 34 patients (68%) showed body image disorders (BID), with a GSI score ≥1.2 and 24 (48%) referred an abuse during childhood. Patients with Axis II disorder or a body image uneasiness or a history of maltreatment during childhood, showed higher BMI in adulthood., Conclusions: Psychiatric comorbidities in obese patients were not only represented by depression or anxiety (Axis I disorders), but also by personality disorders (Axis II), body image disorders and childhood abuse. The identification of these conditions could improve outcomes of bariatric surgery and represent an indication for a most important psychiatric support before, during and after surgery.
