Vitamin E treatment in pediatric obesity-related liver disease: a randomized study.

Objective: A beneficial role of antioxidants in hepatopathic obese individuals has hitherto been inferred only from uncontrolled pilot studies. The authors compared the effect of vitamin E and weight loss on transaminase values and on ultrasonographic bright liver in a controlled group of children with obesity-related liver dysfunction.

Methods: Twenty-eight children with obesity-related hypertransaminasemia and bright liver were randomly allocated to two single-blind groups: group 1 (n = 14) treated with a low-calorie diet associated with oral placebo for 5 months, and group 2 (n = 14) treated with a low-calorie diet associated with oral vitamin E (400 mg/d x 2 months, 100 mg/d x 3 months).

Cerebellar vermis defect, oligophrenia, congenital ataxia, and hepatic fibrocirrhosis without coloboma and renal abnormalities: report of three cases.

We describe 3 children (2 siblings aged 10 and 3 years, and 1 sporadic case aged 13 years) with cerebellar vermis defect associated with oligophrenia, congenital ataxia, and hepatic fibrocirrhosis. Differently from what is reported in COACH syndrome, coloboma and renal involvement were absent. Since in one patient hepatic involvement was subclinical and early therapy seemed to prevent disease progression, the presence of liver disease should be carefully investigated in any patient with ataxia and midline cerebellar defects.

Gastric electrical dysrhythmias and delayed gastric emptying in gastroesophageal reflux disease.

Objective: Deranged gastric motility and delayed gastric emptying are commonly implicated in the pathophysiology of gastroesophageal reflux disease. We measured gastric electrical activity and gastric emptying time of a solid-liquid meal by electrogastrography and antral ultrasound, respectively, in 42 patients with gastroesophageal reflux disease (age 7.4 +/- 1.

Effects of omeprazole on mechanisms of gastroesophageal reflux in childhood.

Prolonged recordings of esophageal motility have shown that dynamic changes of lower esophageal sphincter (LES) pressure such as transient LES relaxation and LES pressure drifts are the most common mechanisms underlying gastroesophageal reflux (GER). The coexistence of a delayed gastric emptying has also been reported in a high proportion of patients with reflux disease. However, not much information is available on the effects of antireflux therapy on the pathogenetic mechanisms of GER.
