Evaluation and Management of Psychiatric Emergencies in Children.

Mental illness among children and adolescents is an increasing burden, projected to become one of the world's leading disabilities in near future. A dearth of specialized services and personnel to provide optimal care affects the disease burden, prevalence, health care services, and health care costs. The increasing demand weighs down on generalized systems of care such as emergency department (ED) services, in which the lack of specific training, personnel, and specialized protocols tends to prolong length of stay, recidivism, and suboptimal care.

Implementing Integrated Care in Pediatric Mental Health: Principles, Current Models, and Future Directions.

Traditional models of health care delivery are inadequate for addressing all the needs of the child and adolescent population that has mental illness. The integrated care model seeks to partner pediatric mental health specialists with primary providers to better meet these needs. The authors outline the core principles guiding integrated care for youths and describe key characteristics of the team members involved.

Assessment and Treatment of Adolescent Substance Use Disorders: Alcohol Use Disorders.

Alcohol drinking in childhood and adolescence is a serious public health concern. Adolescence is a vulnerable period for risk-taking tendencies. Understanding the influences of problematic alcohol use is important for evolving interventions.

Early postnatal alcohol exposure reduced the size of vibrissal barrel field in rat somatosensory cortex (SI) but did not disrupt barrel field organization.

Prenatal alcohol exposure (PAE) has been shown to alter the somatosensory cortex in both human and animal studies. In rodents, PAE reduced the size, but not the pattern of the posteromedial barrel subfield (PMBSF) associated with the representation of the whiskers, in newborn, juvenile, and adult rats. However, the PMBSF is not present at birth, but rather first appears in the middle of the first postnatal week during the brain-growth spurt period.

Long-term effects of prenatal alcohol exposure on the size of the whisker representation in juvenile and adult rat barrel cortex.

Children of mothers who abused alcohol during pregnancy are often reported to suffer from growth retardation and central nervous system (CNS) abnormalities. The use of prenatal alcohol exposed (PAE) animal models has revealed reductions in body and brain weights as well as regional specific brain deficits in neonatal pups. Recently, we and others reported reductions in the size of the posteromedial barrel subfield (PMBSF) in first somatosensory cortex (SI) associated with the representation of the large mystacial vibrissae in neonatal rats and mice that were exposed to alcohol at various times during gestation.

Prenatal alcohol exposure delays the development of the cortical barrel field in neonatal rats.

In-utero alcohol exposure produces sensorimotor developmental abnormalities that often persist into adulthood. The rodent cortical barrel field associated with the representation of the body surface was used as our model system to examine the effect of prenatal alcohol exposure (PAE) on early somatosensory cortical development. In this study, pregnant female rats were intragastrically gavaged daily with high doses of alcohol (6 gm/kg body weight) throughout the first 20 days of pregnancy.

Prenatal alcohol exposure (PAE) reduces the size of the forepaw representation in forepaw barrel subfield (FBS) cortex in neonatal rats: relationship between periphery and central representation.

Prenatal alcohol exposure (PAE) alters limb development that may lead to structural and functional abnormalities of the limb reported in children diagnosed with Fetal Alcohol Spectrum Disorder. To determine whether PAE alters the central representation of the forelimb we used the rodent barrel cortex as our model system where it was possible to visualize and quantitatively measure the size of the forepaw representation in the forepaw barrel subfield (FBS) in first somatosensory cortex. In the present study, we examined the effects of PAE on pattern and size of the forepaw and forepaw representation in FBS in neonatal rats at gestational day 32 that corresponds to postnatal day 9.

Prenatal alcohol exposure alters the size, but not the pattern, of the whisker representation in neonatal rat barrel cortex.

Maternal alcohol exposure results in a variety of neurodevelopmental abnormalities that include cognitive and sensorimotor dysfunctions that often persist into adulthood. Many reports of central nervous system disturbances associated within a clinical diagnosis of fetal alcohol syndrome point toward disturbances in central information processing. In this study, we used the rat barrel field cortex as a model system to examine the effects of prenatal alcohol exposure (PAE) on the organization and size of the large whisker representation in layer IV of the posteromedial barrel subfield (PMBSF) in somatosensory cortex.
