Do serum BDNF levels vary in self-harm behavior among adolescents and are they correlated with traumatic experiences?

The aim of this study was to compare serum brain-derived neurotrophic factor (BDNF) levels between adolescents that harm themselves, those that receive psychiatric treatment but do not harm themselves, healthy adolescents, and childhood traumas and to investigate the relationship between traumatic experiences and serum BDNF levels. The cases were divided into two groups of 40 adolescents exhibiting self-harm behavior (self-harm/diagnosed group) and 30 adolescents receiving psychiatric treatment but not exhibiting self-harm behaviors (non self-harm/diagnosed group). The control group (healthy control group) consisted of 35 healthy adolescents with no psychiatric disorders or self-harm behaviors. The adolescents were asked to fill in the Inventory of Statements About Self Injury (ISAS) and Childhood Trauma Questionnaire (CTQ). For BDNF measurement, blood samples were taken from the cases and controls. The serum BDNF level of self-harming adolescents who used the self-cutting method was significantly lower than that of other groups, and serum BDNF levels decreased with the increase in the emotional neglect and abuse severity of self-harming adolescents during childhood. In our study, serum BDNF levels decreased with the increase in emotional abuse in self-harming adolescents. This finding may indicate that neuroplasticity can be affected by a negative emotional environment during the early period.

Triage of Patients in the Child and Adolescent Psychiatry Outpatient Clinic.

INTRODUCTION: The aim of this study was to evaluate and describe the three-stage triage method used in a child and adolescent psychiatry outpatient clinic. METHOD: The study investigated the new allocation process of 1482 children and adolescents who were assessed using this triage system for the duration of one year, in the year 2005. Data of 1423 children and adolescents who presented in 2003 regarding the waiting time for the first appointment and the rate of nonattendance at the first appointment were used for the comparison. In triage system, new patients presenting to the outpatient clinic in the morning four days a week were assessed by a three-stage procedure: An initial Strengths and Difficulties Questionnaire screening and a structured interview administered by an intern was then followed by a clinical interview. RESULTS: Of the 1482 children and adolescents who presented to the outpatient clinic during the study period, 1291 were given further appointments. Among patients who presented in 2005, the 207 non-attendant patients were significantly more likely to have longer waiting times than the 1084 attendant patients. When compared to year 2003, it was found that there was a significant decrease in the median waiting time for the first appointment and the rate of nonattendance at the first appointment among patients who presented in 2005. CONCLUSION: The triage procedure used in this study may constitute a model for developing countries with limited health care resources.

Amisulpride treatment of adolescent patients with schizophrenia or schizo-affective disorders.

In this article, our aim was to share our clinical experience regarding the effectiveness and the side effects of amisulpride treatment in adolescent cases. We reviewed all the cases who had amisulpride treatment during their stay in a newly opened in-patient unit, and three female cases who had undergone amisulpride treatment. We observed that the drug was effective and caused side effects like galactorrhea due to increased prolactin levels, which were not severe enough to terminate the treatment. Our clinical experience provides preliminary evidence that amisulpride might be an effective antipsychotic drug for adolescent cases. However, it caused considerable side effects.

Nitric oxide levels in disruptive behavioral disorder.

There are various evidences of the role of nitric oxide (NO) in several neuropsychiatric disorders. However, there is no clinical study which investigated the role of NO in disruptive behavioral disorders (DBD). The aim of this study is to investigate the relation between NO levels and DBD. NO levels were measured in serum from 45 patients diagnosed as having DBD (30 patients with a diagnosis of attention deficit and hyperactivity disorder [ADHD] and 15 with ADHD + oppositional defiant disorder [ODD]) and 51 healthy control subjects. It is statistically significant that the pure ADHD group's blood NO levels are lower than those of both the ADHD + ODD and control groups. There was no significant difference between the ADHD + ODD group and the controls. The difference of the NO levels in DBD may indicate the effect of NO in the etiology of this disorder spectrum.
