Obesity ranks as a leading chronic pediatric disorder, with estimates ranging from 10 to 25% of the childhood and adolescent population. Physical hypoactivity is prevalent among obese youth and may be an etiological factor. Physical training, with or without nutritional intervention, has been found effective for weight and body fat control. The purpose of this paper is to examine the role that the physician and physical education teacher can play in the treatment of obesity at school. Studies of school-based intervention programs utilizing exercise, nutrition and behavior modification are reviewed. Suggestions are outlined for school-based obesity programs.

Rapid-onset Obesity with Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation (ROHHAD) is a rare and complex pediatric disorder. Despite increased identification and advancing knowledge of the disease course, the variable onset and timing of phenotypic features in ROHHAD often result in delayed or missed diagnosis, potentially leading to fatal central hypoventilation, cardiorespiratory arrest, and impaired neurocognitive development. The 5-hydroxytryptamine receptor 1A (HTR1A), orthopedia (OTP), and pituitary adenylate cyclase activating polypeptide (PACAP) genes were targeted in the etiology of ROHHAD based on their roles in the embryologic development of the hypothalamus and autonomic nervous system. We hypothesized that variations of HTR1A, OTP, and/or PACAP would be associated with ROHHAD. All coding regions and intron-exon boundaries of the HTR1A, OTP, and PACAP genes, in addition to the promoter region of the HTR1A gene, were analyzed by standard sequencing in 25 ROHHAD cases and 25 matched controls. Thirteen variations, including six protein-changing mutations, were identified. None of these variations were significantly correlated with ROHHAD. This report provides evidence that variation of the HTR1A, OTP, and PACAP genes are not responsible for ROHHAD. These results represent a further step in the investigation of the genetic determinants of ROHHAD.

Over the past decade, non-alcoholic fatty liver disease (NAFLD) has become one of most common chronic liver diseases in children. A greater understanding about the risk factors and molecular pathogenesis of NAFLD suggests that lifestyle interventions aiming to decrease obesity/body mass index and metabolic derangement are the first line of treatments adopted in children affected by this disease. However, because these therapeutic options are often at the beginning misjudged by the patients and their parents, the use of pharmacologic agents may help to protect the liver and other organs from further irreversible tissue damage. Pharmacologic therapies against one or more specific factors and/or molecules involved in the development of NAFLD (i.e., insulin resistance, free fatty acid lipid toxicity, and oxidative stress) also might slow the progression of this increasingly prevalent pediatric disorder. On this basis, insulin sensitizers, antioxidants, cytoprotective agents, and dietary supplementations have been evaluated in pediatric clinical trials. In this review, we discuss the efficacy of the dietary approaches, possibly coupled with regular exercise, on decreasing the metabolic and histologic damage in pediatric NAFLD. We also emphasize several advantages of the pharmacologic treatments adopted or adoptable in combination with lifestyle interventions in children with NAFLD.

Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation syndrome (ROHHADS) is a rare, but potentially lethal, pediatric disorder. To date, nearly 80 patients have been reported in the literature; however, the etiopathogenesis is still unclear and debated. Both genetic and paraneoplastic or immune-mediated causes have been supposed to be involved in this syndrome. Nonetheless, at this time, a diagnostic biomarker is not available and diagnosis is based exclusively on clinical criteria. Aiming to establish the immune-mediated pathogenesis, we report 2 children with a clinical picture consistent with ROHHADS and whose cerebrospinal fluid analysis disclosed an intrathecal synthesis of oligoclonal bands. Even if many aspects remain to be explained, this finding suggests that ROHHADS could share similar pathogenetic mechanisms with other immune-mediated central nervous system disorders, and even more important, it might pave the way to a therapeutic chance for these patients by means of immunotherapy.
