Morphometric characteristics of the neuro ns of the human subiculum proper
The human subiculum is a significant part of the hippocampal formation positioned between the hippocampus proper and the entorhinal and other cortices. It plays an important role in spatial navigation, memory processing and control of the response to stress. The aim of our study was identification of the morphometric characteristics of the neurons of the human subiculum proper: the maximum length and width of cell body and total dendritic length and volume of cell body. Comparing the measured parameters of different types of subicular neurons (bipolar, multipolar, pyramidal neurons with triangular-shaped soma and neurons with oval-shaped soma), we can conclude that bipolar neurons have the lowest values of the measured parameters: the maximum length of their cell body is 14.1 ± 0.2 μm, the maximum width is 13.9 ± 0.5 μm, and total dendritic length is 14597 ± 3.1 μm. The lowest volume value was observed in bipolar neurons; the polymorphic layer is 1152.99 ± 662.69 μm 3. The pyramidal neurons of the pyramidal layer have the highest value for the maximal length of the cell body (44.43 ± 7.94 μm), maximum width (23.64 ± 1.89 μm), total dendritic length (1830 ± 466.3 μm) and volume (11768.65±4004.9 μm 3) These characteristics of the pyramidal neurons indicate their importance, because the axons of these neurons make up the greatest part of the fornix, along with the axons of neurons of the CA1 hippocampal field
Depressive symptoms, exposure to aggression and delinquency proneness in adolescence: Impact of two decades of war and political violence on adolescent mental health
Traumatic experiences in Serbia in the last two decades have caused significant psychological consequences in children and adolescents. The aim of this study was to investigate the relationship between depressive symptoms, exposure to aggression and delinquency proneness among high school and elementary school students in Belgrade, Serbia. The participants were 899 students (51.8% were female) with no prior treatment for psychological problems, with a mean age of 16.70±1.95. All used instruments were taken from the modified Social and Health Assessment (SAHA). Our findings show that delinquent behavior or exposure to delinquency was significantly related to depressive symptoms. The strongest predictors of depression were variables concerning legal consequences, affiliation with delinquent peers, victimization by community violence and peer victimization. This study confirmed a strong correlation between depression and exposure to violence. Identifying adolescents with depressive symptoms is important for prevention of serious mental health consequences
Internet addiction: A case report
Some addictions cannot be connected with substance abuse (pathological) gambling, video games playing, binge eating, compulsive physical activity, emotional relationship addiction, TV addiction). Since 1995, Internet addiction has been accepted as a clinical entity with profound negative effect on social, familial, educational and economical personal functioning. The diagnosis of Internet addiction could be established if the person spends more than 38 hours per week on the Internet exempting online professional needs. Basic symptoms are the increased number of hours spent in front of the computer along with the Internet use, development of abstinent syndrome if the Internet access is prohibited, sleep inversion, neglect of basic social requirements and personal hygiene, many somatic symptoms developed due to prolonged sitting or monitor watching, dissocial behavior. In this paper, data about the Internet addiction are presented and a case report of an adolescent with developed Internet addiction
Adjustment disorders in hospital treated adolescents: A follow-up study
Introduction. Adjustment disorders represent a frequent diagnostic entity especially among adolescents. They involve a wide spectrum of various emotional and behaviour problems. Objective. The aim was to investigate characteristics of diagnostic category known as adjustment disorders among hospital treated adolescents for the first time at the Clinical Department for Children and Adolescents of the Institute of Mental Health in Belgrade, during five consecutive years, as well as to investigate the outcome of the disorder in follow-up period. Methods. We conducted a retrospective investigation of the first time hospital treated adolescents from Belgrade with discharge diagnosis of adjustment disorders during 2000-2004. The follow up was conducted 5-10 years after a first discharge from the hospital. Results. During the investigated period 75 adolescents from Belgrade were hospitalized for the first time with diagnosis adjustment disorder. From the studied patients the main sample was formed that included 24 (32%) males and 51 (68%) females. After 5-10 years a follow-up of 52 patients was conducted (sample at follow-up) which included 16 (30.77%) males and 36 (69.23%) females. Of the main sample, 70% of the patients were under follow-up. After the first hospitalization 58% of adolescents continued with further psychiatric treatment, either as rehospitalized or out-of-hospital patients. Conclusion. Our findings showed that 38% of adolescents under follow-up for 5-10 years after the first discharge from hospital with the diagnosis adjustment disorders had multiple hospitalizations. The outcome of the disorder among these patients was the worst, because three-quarters of the patients were rediagnosed in the follow-up period with a new psychiatric disorder, often from psychotic spectrum
