Do social interaction behaviors discriminate young children with autism and Williams syndrome?
Although some children with WS demonstrated some ASD behaviors, and a minority of children with WS had coexisting AD, the symptom profile in WS was different from AD. Despite some deficits in communication behaviors, showing, and initiating joint attention, children with WS made social overtures and efforts to engage others, whereas children with AD tended not to do so.
A high BMI is not associated with increased overall morbidity following esophagectomy; moreover, it is associated with decreased incidence of chylothorax. The better overall survival in patients with high BMI compared with those with low BMI might be due to a relatively low pathological stage. A high BMI should therefore not be a relative contraindication for esophagectomy.
