Impaired glucose tolerance is highly prevalent among children and adolescents with severe obesity, irrespective of ethnic group. Impaired oral glucose tolerance was associated with insulin resistance while beta-cell function was still relatively preserved. Overt type 2 diabetes was linked to beta-cell failure.

RHs are seen more often in abusive head injury and often are bilateral and involve the preretinal layer. Children with abusive head injury were more likely to have RHs that cover the macula and extend to the periphery of the retina. Unilateral RHs can be seen in children with accidental head injury. Children with abusive head injury were more likely to present with abnormal mental status and seizures, whereas children with accidental head injury were more likely to have scalp hematomas. Such characteristics may be useful to distinguish accidental from abusive head trauma in children <24 months of age.

The zoonotic ascarid Toxocara has been suggested as a possible etiologic agent of asthma. We conducted a clinic-based case-control study to examine whether the zoonotic infection acquired by ingesting Toxocara eggs is associated with asthma in children. Blood samples were collected from children aged 2-15 years, 95 of whom had asthma and 229 of whom did not have asthma. Risk factors for asthma and Toxocara infection were assessed by a questionnaire given to each child's parent or legal guardian. Blood samples were tested for the presence of Toxocara antibodies, using an enzyme-linked immunosorbent assay. No significant association was found between Toxocara infection and asthma. Significant associations were found between asthma and risk factors and between Toxocara infection and risk factors. High prevalence of Toxocara infection was noted among Hispanic children of Puerto Rican descent.

Children are less anxious and show increased compliance during induction when exposed to a single care-provider in a dimmed, quiet operating room with background music.

A significant number of children undergoing outpatient surgery experience postoperative sleep-related problems. The clinical significance of this finding, however, is unclear.
