This review summarizes efficacious treatments for preschoolers, children and adolescents with post-traumatic stress disorder, with a focus on the advances made within the last 5 years. There is considerable support for the use of trauma-specific cognitive-behavioral interventions, in both individual and group formats. The research on psychopharmacological treatments lags behind that of psychotherapy and is currently inconclusive. Limitations of the studies are discussed and treatments that warrant further consideration are reviewed. The authors also review current advances in effectiveness and suggest future directions that are important in generalizing the interventions to underserved and hard to reach populations. The article concludes with the authors' projections for the evolution of the field within the upcoming 5 years

OBJECTIVES: This study aimed to examine whether pediatric autoimmune neuropsychiatric disorders associated with streptococcus were appropriately diagnosed in the community and to determine subsequent rates of unwarranted use of antibiotic treatment for tics and obsessive-compulsive symptoms without the identification of an infection. METHODS: The design was a retrospective, cross-sectional, observational study of 176 children and adolescents who were evaluated in a specialty program for tics, Tourette's disorder, and related problems. Previously published diagnostic criteria were used to establish the diagnosis of pediatric autoimmune neuropsychiatric disorders associated with streptococcus in our clinic. RESULTS: Subjects were significantly less likely to receive a diagnosis of pediatric autoimmune neuropsychiatric disorders associated with streptococcus at the specialty clinic than in the community. In the community, subjects were significantly more likely to be treated with antibiotics or immunosuppressant medication if they received a diagnosis of pediatric autoimmune neuropsychiatric disorders associated with streptococcus. Of the 27 subjects with a community diagnosis of pediatric autoimmune neuropsychiatric disorders associated with streptococcus who were treated with antibiotics, 22 (82%) were treated without laboratory evidence of an infection; 2 were treated with immunomodulatory medications. CONCLUSIONS: Our results support our hypothesis that pediatric autoimmune neuropsychiatric disorders associated with streptococcus are frequently diagnosed in the community without the application of all working diagnostic criteria. This phenomenon has resulted in unwarranted use of antibiotic treatment for tics/obsessive-compulsive disorder without evidence of laboratory infection

Investigations examining the role of polysialic acid (PSA) on the neural cell adhesion molecule (NCAM) in synaptic plasticity have yielded inconsistent data. Here, we addressed this issue by determining whether homosynaptic long-term potentiation (LTP) and heterosynaptic long-term depression (LTD) induce changes in the distribution of PSA-NCAM in the dentate gyrus (DG) of rats in vivo. In addition, we also examined whether the observed modifications were initiated via the activation of N-methyl-D-aspartate (NMDA) receptors. Immunocytochemical analysis showed an increase in PSA-NCAM positive cells both at 2 and 24 h following high-frequency stimulation of either medial or lateral perforant paths, leading to homosynaptic LTP and heterosynaptic LTD, respectively, in the medial molecular layer of the DG. Analysis of sub-cellular distribution of PSA-NCAM by electron microscopy showed decreased PSA dendritic labelling in LTD rats and a sub-cellular relocation towards the spines in LTP rats. Importantly, these modifications were found to be independent of the activation of NMDA receptors. Our findings suggest that strong activation of the granule cells up-regulates PSA-NCAM synthesis which then incorporates into activated synapses, representing NMDA-independent plastic processes that act synergistically on LTP/LTD mechanisms without participating in their expression.

BACKGROUND: Many children who have a mental health disorder do not receive mental health services and are seen only in primary care settings. Perceptions of pediatricians and mental health specialists regarding the role that pediatricians should have in diagnosing and managing children's mental health problems have not been studied. OBJECTIVE: To examine whether primary care pediatricians (PCPs) and child and adolescent psychiatrists (CAPs) agree about: (1) the pediatrician's role in identification, referral, and treatment of childhood mental health (MH) disorders; and (2) barriers to the identification, referral, and treatment of childhood MH disorders. METHODS: Surveys were mailed in 2005 to 338 PCPs and 75 CAPs in 7 counties surrounding Cleveland, Ohio. Each group was asked whether they agreed that PCPs should be responsible for identifying, treating, or referring 7 prevalent childhood MH problems. Barriers that PCPs face in identification, referral, and treatment of MH problems were also assessed. Analyses were weighted for nonresponse; group differences were assessed via Rao-Scott chi test and weighted regression analyses. RESULTS: Approximately half of PCPs and CAPs returned the survey. With the exception of attention deficit hyperactivity disorder (ADHD), the majority of PCPs and CAPs agreed that pediatricians should be responsible for identifying and referring, but not treating child MH conditions. For ADHD, PCPs were more likely than CAPs to agree that pediatricians should identify and treat affected children. PCPs were more likely than CAPs to agree that pediatricians should be responsible for identifying child/adolescent depression and anxiety disorders; the majority of both groups agree that PCPs should be responsible for referring, but not treating these conditions. Both groups agree that lack of MH services is a barrier to identification, treatment, and referral of child MH problems for PCPs. CAPs were more likely to agree that pediatrician's lack of training in identifying child mental health problems was a barrier, whereas PCPs were more likely to endorse lack of confidence in their ability to treat child MH problems with counseling, long waiting periods to see MH providers, family failure to follow through on referrals, and billing/reimbursement issues as barriers. CONCLUSIONS: Most PCPs and CAPs believe it is pediatricians' responsibility to identify and refer, but not treat, the majority of children's mental health problems. Both groups agree that mental health services are not readily available. Future efforts are needed to support PCPs and CAPs in their combined effort to address the mental health needs of children.

OBJECTIVES: To test the effectiveness of the CHAMP among black South Africans in KwaZulu-Natal, South Africa. METHODS: A randomized control trial was conducted in KwaDedangendlale, South Africa, among youths (ages 9-13) and their families (245 intervention families rearing 281 children and 233 control families rearing 298 children). The CHAMPSA intervention targeted HIV risk behaviors by strengthening family relationship processes as well as targeting peer influences through enhancing social problem solving and peer negotiation skills for youths. RESULTS: Among caregivers in the control and experimental conditions, significant intervention group differences were revealed regarding HIV transmission knowledge, less stigma toward HIV-infected people, caregiver monitoring-family rules, caregiver communication comfort, caregiver communication frequency and social networks. Among youths, data revealed that control and experimental groups were significantly different for children in AIDS transmission knowledge and less stigma toward HIV-infected people. CONCLUSIONS: CHAMPSA enhances a significant number individual, family and community protective factors that can help youths avoid risky behaviors leading to HIV-positive status.

Recent studies have indicated a role for the endocannabinoid system in ethanol-related behaviors. This study examined the effect of pharmacological activation, blockade, and genetic deletion of the CB(1) receptors on ethanol-drinking behavior in ethanol preferring C57BL/6J (B6) and ethanol nonpreferring DBA/2J (D2) mice. The deletion of CB(1) receptor significantly reduced the ethanol preference. Although the stimulation of the CB(1) receptor by CP-55,940 markedly increased the ethanol preference, this effect was found to be greater in B6 than in D2 mice. The antagonism of CB(1) receptor function by SR141716A led to a significant reduction in voluntary ethanol preference in B6 than D2 mice. A significant lower hypothermic and greater sedative response to acute ethanol administration was observed in both the strains of CB(1) -/- mice than wild-type mice. Interestingly, genetic deletion and pharmacological blockade of the CB(1) receptor produced a marked reduction in severity of handling-induced convulsion in both the strains. The radioligand binding studies revealed significantly higher levels of CB(1) receptor-stimulated G-protein activation in the striatum of B6 compared to D2 mice. Innate differences in the CB(1) receptor function might be one of the contributing factors for higher ethanol drinking behavior. The antagonists of the CB(1) receptor may have therapeutic potential in the treatment of ethanol dependence

STUDY OBJECTIVES: To explore age differences in the relationship between sleep duration and mortality by conducting analyses stratified by age. Both short and long sleep durations have been found to be associated with mortality. Short sleep duration is associated with negative health outcomes, but there is little evidence that long sleep duration has adverse health effects. No epidemiologic studies have published multivariate analyses stratified by age, even though life expectancy is 75 years and the majority of deaths occur in the elderly. DESIGN: Multivariate longitudinal analyses of the first National Health and Nutrition Examination Survey using Cox proportional hazards models. SETTING: Probability sample (n = 9789) of the civilian noninstitutionalized population of the United States between 1982 and 1992. PARTICIPANTS: Subjects aged 32 to 86 years. MEASUREMENTS AND RESULTS: In multivariate analyses controlling for many covariates, no relationship was found in middle-aged subjects between short sleep of 5 hours or less and mortality (hazards ratio [HR] = 0.67, 95% confidence interval [CI] 0.43-1.05) or long sleep of 9 hours or more and mortality (HR = 1.04, 95% CI 0.66-1.65). A U-shaped relationship was found only in elderly subjects, with both short sleep duration (HR = 1.27, 95% CI 1.06-1.53) and long sleep duration (HR = 1.36, 95% CI 1.15-1.60) having significantly higher HRs. CONCLUSIONS: The relationship between sleep duration and mortality is largely influenced by deaths in elderly subjects and by the measurement of sleep durations closely before death. Long sleep duration is unlikely to contribute toward mortality but, rather, is a consequence of medical conditions and age-related sleep changes
