Lateralization of Neurobiological Response in Adolescents with Post-Traumatic Stress Disorder Related to Severe Childhood Sexual Abuse: the Tri-Modal Reaction (T-MR) Model of Protection

ABSTRACT This study inquires into neurobiological response to stress and its clinical correlates among adolescents with post-traumatic stress disorder (PTSD). Structural magnetic resonance imaging (MRI) measures of cerebral anatomy were carried out on 23 female adolescents with PTSD related to severe childhood sexual abuse and 21 matched healthy controls. Clinician Administered PTSD Scale for Children and Adolescents, Adolescent Dissociative Experiences Scale, Childhood Trauma Questionnaire, Schedule for Affective Disorders and Schizophrenia for School Age Children, Beck Depression Scale, and a set of neuro-cognitive tests were administered to all participants. Compared to controls, PTSD group bilaterally had smaller amygdala, hippocampus, anterior cingulate, and thinner prefrontal cortex but normal thalamus. Further analyses within the PTSD group suggested an association between symptoms of PTSD and sizes of right brain structures including smaller amygdala but larger hippocampus and anterior cingulate. Thinner right prefrontal cortex and larger right thalamus seemed to be related to denial and response prevention, respectively. Being related to both hemispheres, dissociative amnesia was negatively associated with proportion of the right amygdala to right thalamus and to both left and right prefrontal cortex. Suggesting a neuro-protective effect against traumatic stress at least through adolescence, depersonalization–derealization and identity alteration were correlated with thicker left prefrontal cortex. Unlike the lateralization within PTSD group, correlations between regions of interest were rather symmetrical in controls. The graded response to stress seemed to be aimed at mental protection by lateralization of brain functions and possibly diminished connection between two hemispheres. A Tri-Modal Reaction (T-MR) Model of protection is proposed.

What happens to children who move off the autism spectrum? Clinical follow-up study

There is controversial information on outcome of school age individuals who lose the diagnosis of autism and achieve “optimal outcome” (OO). The present study assessed the autism symptoms and other psychiatric disorders in a group of children with a past history of autism.

Understanding the associations between psychosocial factors and severity of crime in juvenile delinquency: a cross-sectional study

Purpose Juvenile delinquency is a serious and common problem. To date, several studies have focused on possible psychosocial risk factors for delinquency among youths and on the implications of childhood mental illness on child criminality. However, the literature on prevalence of psychopathology and predictors of crime severity among delinquent youths in Turkey is sparse. Therefore, the aim of this study was to show the associations between crime severity and psychosocial factors such as gender, age, criminal history, concomitant attention deficit hyperactivity disorder (ADHD) and other comorbid psychiatric conditions, along with behavioral problem domains of Child Behavior Checklist (CBCL). Participants and methods This analytical cross-sectional study sample consisted of 52 individuals (30 females and 22 males) who were sent to a pilot detention facility in Istanbul, Turkey. The participants’ age ranged from 8 to 18 years (M =13.4; SD =2.9). Self-rating scales were administered in an interview format, and the crime severity information was provided by participants’ admission documents. Results No differences were found in terms of gender, age, children’s past history of crime and substance abuse. However, family crime history was significantly higher in the high severity crime group (P=0.026). Having one or more comorbid psychiatric disorder was associated with high crime severity (P=0.018). The most common psychiatric disorders were found to be ADHD, oppositional defiant disorder, conduct disorder (CD) and anxiety disorder. Conclusion Findings suggest that a family history of crime comes across as a very strong predictor of severity of crime. Among psychiatric factors, ADHD and CD were associated with commitment of more severe crimes in delinquent youths in our sample. Anxious/depressed traits as depicted by CBCL are found to be associated with less severe crimes.

Three adolescent cases of a very rare disorder: Trichotemnomania

ABSTRACT Trichotemnomania (TT) is characterized as the cutting or shaving of hair, which is an obsessive–compulsive habit. TT takes its name from a fusion of Greek words: thrix (hair), temnein (to cut), and mania (madness). TT is a very rare disease with only five case studies reported in the literature and to the best of our knowledge; no data are available on adolescents. This study focuses on three cases of adolescents with TT. All patients have been evaluated by a dermatologist and two child and adolescent psychiatrists. Dermatological examinations included medical history, physical examination, dermoscopy assessment, and laboratory investigations. Detailed psychiatric assessments consisted of socio-demographic data, clinical history, semi-structured interviews, and psychometric tests. Three cases with TT were both diagnosed with obsessive–compulsive disorder. Two of them diagnosed comorbid social anxiety disorder (in cases 1 and 2), and one case diagnosed with comorbid general anxiety disorder (in case 3) and agoraphobia (in case 3). Cases 1 and 2 were prescribed 50u2005mg/day of sertraline; however, case 3 refused the treatment. In conclusion, TT may be confused with trichotillomania or other disorders presented with alopecia. Differential diagnoses may be due to histopathological changes or dermoscopic assessment. Dermatologists should consider TT when a supposed alopecia areata looks somewhat unusual and should refer these patients for psychiatric evaluation.
