Autism is characterized by impairments in reciprocal communication and social interaction and by repetitive and stereotyped patterns of activities and interests. Evidence for a strong underlying genetic predisposition comes from twin and family studies, although susceptibility genes have not yet been identified. A whole-genome screen for linkage, using 83 sib pairs with autism, has been completed, and 119 markers have been genotyped in 13 candidate regions in a further 69 sib pairs. The addition of new families and markers provides further support for previous reports of linkages on chromosomes 7q and 16p. Two new regions of linkage have also been identified on chromosomes 2q and 17q. The most significant finding was a multipoint maximum LOD score (MLS) of 3.74 at marker D2S2188 on chromosome 2; this MLS increased to 4.80 when only sib pairs fulfilling strict diagnostic criteria were included. The susceptibility region on chromosome 7 was the next most significant, generating a multipoint MLS of 3.20 at marker D7S477. Chromosome 16 generated a multipoint MLS of 2.93 at D16S3102, whereas chromosome 17 generated a multipoint MLS of 2.34 at HTTINT2. With the addition of new families, there was no increased allele sharing at a number of other loci originally showing some evidence of linkage. These results support the continuing collection of multiplex sib-pair families to identify autism-susceptibility genes.

BACKGROUND This study examined prospectively the activity of the hypothalamic-pituitary-adrenal axis, the sympathetic nervous system and inflammatory factors in children shortly after a motor vehicle accident (MVA) in relation to later posttraumatic stress disorder (PTSD) development. PATIENTS AND METHODS Fifty six children, aged 7-18, were studied after an MVA and 1 and 6 months later; 40 subjects served as controls. Morning serum cortisol and interleukin (IL)-6 and plasma catecholamine concentrations were measured within 24h after the event. Salivary cortisol was measured 5 times at defined time points during the same day. PTSD diagnoses 1 and 6 months later were based on K-SADS interview. RESULTS Morning serum IL-6 concentrations, measured within the first 24h after the accident, were higher in children that developed PTSD 6 months later than those who did not and those of the control group. Longitudinal IL-6 measurements revealed normalization of IL-6 in the PTSD group, while no differences between the three groups were detected 1 and 6 months later. Evening salivary cortisol and morning serum IL-6 after the accident were positively inter-related (r=0.54, p<0.001) and in separate regression analyses both predicted PTSD development 6 months later. In contrast, morning serum IL-6 did nor correlate with morning serum or salivary cortisol concentrations. CONCLUSIONS Immediate posttraumatic alterations in neuroendocrine or inflammatory factors-increased evening salivary cortisol and/or increased morning serum IL-6 concentrations-are involved in subsequent PTSD development in children and adolescents.

Abstract.The objective of the present study was to assess symptoms of posttraumatic stress disorder (PTSD), depression and anxiety among children 6 months after they had been exposed to an earthquake (EQ) affecting the northwestern suburbs of Athens in September 1999. A total of 115 children attending two elementary schools located at the epicentre of the EQ were assessed. A group of 48 children not affected by the EQ attending a school not affected by the EQ were used as controls. The children and their parents completed a number of questionnaires. Overall, there was a high rate (78%) of severe to mild PTSD symptoms in the EQ exposed group. Additionally, a substantial proportion of these children scored above criteria (32%) for depression compared to the control group (12.5%). Severe or moderate symptoms of PTSD were associated with high scores of depression (p = 0.002). The relationship between PTSD symptoms and anxiety was limited to the “avoidance” factor of the anxiety questionnaire (p = 0.029). Those who were most likely to be affected were children alone at the time of the EQ, and children who sustained injuries. In summary, countries where EQs are frequent should be prepared to offer psychological support to a substantial proportion of children presenting with PTSD and depressive symptoms and should educate and prepare children to cope with these events.

BACKGROUND The hypothalamic-pituitary-adrenal axis and the catecholaminergic system are involved in the pathophysiology of post-traumatic stress disorder (PTSD). This was a prospective and longitudinal study of neuroendocrine physiology in children with PTSD following a motor vehicle accident (MVA). METHODS Sixty children aged 7-18 were studied immediately after an MVA and 1 and 6 months later. Fasting morning plasma catecholamine and serum cortisol concentrations were measured. Salivary cortisol concentrations were measured serially five times daily to examine circadian variation in all three assessments. Values were compared between those who did (PTSD) or did not develop PTSD (non-PTSD) after the trauma and a control group at months 1 and 6. RESULTS Twenty-three of the children had PTSD at the 1-month and 9 children at the 6-month evaluations. 1) Plasma noradrenaline concentrations were higher in the PTSD group than in the other two groups at both months 1 and 6 (p = .001 and p = .001, respectively). Additionally, the PTSD patients presented with significantly higher salivary cortisol concentrations at 18.00 (p = .03) and 21.00 (p = .04) at month 1.2) Eight children suffering from PTSD at both months 1 and 6 had significantly elevated plasma noradrenaline concentrations at month 6 compared with those at month 1 and at baseline and to the other two groups (within subjects: p < .001; between subjects: p = .005). The initially elevated evening salivary cortisol concentrations in this group normalized at month 6. CONCLUSIONS This progressive divergence of noradrenaline and cortisol concentrations over time might underlie the natural history and pathophysiology of PTSD.

OBJECTIVES To examine the nature of psychopathology of children with alopecia areata (AA) and to investigate the frequency and quality of life events in the year before AA developed in comparison with a control group. METHOD Thirty-three subjects with AA, mean age 10.5 +/- 0.3 years, were compared with 30 controls who visited a pediatrician for a mild condition. In addition, 16 preschool children with AA were compared with 17 preschool children who visited the pediatrician for a mild condition. The following measures were used: Child Psychiatric Interview, Childrens Depression Inventory (CDI), Childrens Manifest Anxiety Scale (CMAS), Life Events Scale for Children, and Child Behavior Checklist (CBCL). RESULTS On the CBCL, children with AA had more psychological problems, in total, than controls, and in particular, they were more anxious or depressed, withdrawn, aggressive, and delinquent. They also had more somatic problems as well as problems in social relations and in attention. Girls with AA seem to have been affected more in dimensions of total problems, anxiety/depression, and internalizing/externalizing syndromes. In terms of anxiety (CMAS), more children with AA than controls seemed to worry and to have difficulties in concentration and physiological symptoms of anxiety. In the Child Psychiatric Interview, all children with AA exhibited symptomatology of anxiety or depression or both, usually of mild or moderate nature. Major depression was not detected through the CDI. Fewer children with AA had positive life events the year before AA than controls in a similar time period. CONCLUSIONS Compared with controls, children with AA had more psychiatric symptoms in general and symptoms of anxiety or depression, or both, in particular. There is also evidence that lack of positive life events in the prealopecia period played a role in their lives. Psychiatric assessment, and if necessary treatment, is warranted for all children with this condition.

Purpose. The purpose of this study was to assess self-reported depressive and anxiety symptoms in adolescents with polycystic ovary syndrome (PCOS) and those with the rare Mayer-Rokitansky-Küster-Hauser Syndrome (MRKHS), compared with healthy adolescents. Material and methods. The participants were 49 adolescent girls, of whom 27 were patients with confirmed menstrual disorder, 22 with PCOS and 5 with MRKHS; and 22 were healthy eumenorrheic adolescents (control group) matched by age and school grade. The Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI-Gr) were used to measure depression and anxiety, respectively. Results. The results showed that it was 1.08 times more likely for the PCOS group (p = 0.043) and 1.12 times more likely for the MRKHS group (p = 0.039) to have higher scores than healthy adolescents on the anxiety scale. The MRKHS group was 1.40 times more likely to have a higher number of depressive symptoms (p = 0.040) than the control group. Conclusions. These findings, although based on a small sample, suggest a relationship between PCOS and MRKHS and the presence of psychological problems, such as anxiety and depressive symptoms in adolescents. This study is among the first to examine psychological difficulties in adolescents with such a rare menstrual syndrome as MRKHS.

This study explores the psychosocial problems experienced by families with children aged 6 to 14 years suffering from β-thalassemia major (N=188). The psychosocial problems and the familys adjustment to the effects of the illness were compared across a number of cultures where the disease is prevalent, namely Cyprus, Greece, and Italy. A small number of migrant children.in the United Kingdom was also included in the study. Semi-structured interviews were conducted with parents who also completed the Rutter Parental Questionnaire and the Goldberg General Health Questionnaire. Teachers were asked to complete a Childrens Behaviour Questionnaire designed by Rutter. In all countries the disease seemed to have a binding effect on the family, thus mobilizing adaptive mechanisms. Fathers low education level and the presence of major medical complications were predictors of poor family adjustment. Differences between and within countries may well reflect differences in health policies, existing level of socio-economic development, and in the cultural patterns in coping with a chronic illness.

ObjectivesBased on the investigation of 144 families (144 patients affected by Multiple Sclerosis (MS), 109 partners, and 192 children) examined in three different European child and adolescent psychiatric University centres by means of questionnaires, we evaluated the prevalence of psychological symptoms in the offspring and associated risk factors such as duration and severity of the disease as well as depression of the ill and the healthy parent.ResultsIndicate that the severe disease of MS is associated with depression of the ill and healthy parent. Ill parents, especially ill mothers, as well as depressed ill, or depressed healthy parents evaluate their children’s mental health problems with a higher prevalence within the internalizing spectrum. Healthy parents report normal psychological adjustment of their children. If two parents present a depressive state, the prevalence of relevant psychological internalizing symptoms is twice or three times as high as the age norms.ConclusionChildren in families with a parent affected by MS and associated depression of the parental couple are at high risk of mental health problems, especially internalizing disorders. In focusing on the mental health of children one must also be aware of the potential opportunities to address the parents’ own psychological needs.

Abstract Mental health budgets, services and programs are seldom commensurate with mental health needs in the countries, particularly of population groups whose voice in advocacy is weak. In this inquiry we explored the adequacy of mental health care resources available for the young in Europe. To achieve this objective this survey investigated a few variables (e. g., number of services, degree of coverage, trained personnel) that were used as gross indicators of the discrimination suffered by this health sector. We sent a short postal questionnaire to the mental health focal points of the 51 countries included in the World Health Organization European Region. Thirty six countries (70.5 %) responded. The results showed that the degree of coverage and quality of services for the young were generally worse in comparison with those for adults, including for serious disorders. A lack of both specialized and in-training personnel was identified. The exposure of general practitioners and pediatricians to psychiatry for the young was limited. Generally, the lower the income level of the country the worse the situation. Our mapping confirmed findings of previous inquiries. European child psychiatry leaders had raised a set of recommendations to improve the current situation; their implementation can now benefit from novel strategies adopted by the World Health Organization to advance mental health worldwide.

Greece joined the European Community in 1981 and, three years later, the Commission of the European Communities provided financial and technical assistance under EEC Regulation 815/84 for the modernisation of the traditional psychiatric care system, with the emphasis on decentralisation of mental health services and the development of community-based services, as well as on deinstutionalization of long-stay patients and improvement of conditions in public mental hospitals. Over the last 11 years, the implementation of the EEC Reg. 815/84 programme contributed to a significant shift towards extramural care and rehabilitation. The role of the large mental hospitals has gradually been diminished and a large number of long-stay patients have been deinstitutionalised. It is commonly accepted that the EEC-funded psychiatric reform programme, despite inadequacies and constraints, had an impact on the changing mental health scene in Greece.
