BACKGROUND AND OBJECTIVES Gastric acidity is a major nonimmune defense mechanism against infections. The objective of this study was to investigate whether ranitidine treatment in very low birth weight (VLBW) infants is associated with an increased risk of infections, necrotizing enterocolitis (NEC), and fatal outcome. METHODS Newborns with birth weight(More)
BACKGROUND AND OBJECTIVES Total parenteral nutrition (TPN) is a lifesaving therapy in children with intestinal failure, frequently complicated by liver dysfunction. Plant sterols (phytosterols) of lipid emulsions have been supposed to contribute to cholestasis in TPN-treated children. The present study aimed to evaluate the plasma and red blood cell(More)
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(More)
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(More)
OBJECTIVES To characterize both proximal and distal esophageal acid exposure in children with gastroesophageal reflux-related respiratory disease and to investigate the usefulness of dual-channel intraesophageal pH monitoring in these patients. METHODS Continuous simultaneous recording of distal and proximal esophageal pH was performed in 40 patients with(More)
To assess and compare gastric electrical activity and gastric emptying recorded from dyspeptic and healthy children, cutaneous electrogastrography and ultrasound examination of the gastric emptying were simultaneously performed in 52 children with nonulcer dyspepsia and 114 healthy children. Symptoms were scored from 0 (none) to 6 (severe). A higher(More)
BACKGROUND & AIMS High-resolution manometry demonstrates a chain of 3 sequential pressure segments that represent esophageal peristalsis in children and adults. We performed high-resolution manometry in preterm and term neonates to determine the ontogenesis of esophageal motility with regard to this segmental architecture. METHODS Sixteen preterm(More)
Intestinal lymphangiectasia is characterized by obstruction of lymph drainage from the small intestine and lacteal dilation that distorts the villus architecture. Lymphatic vessel obstruction and elevated intestinal lymphatic pressure in turn cause lymphatic leakage into the intestinal lumen, thus resulting in malabsorption and protein-losing enteropathy.(More)
INTRODUCTION Immaturity of motility, intestinal epithelial barrier function and absorptive capacity may play a role in the pathophysiology of intestinal diseases in preterms. We determined the gastric electrical activity and emptying, and intestinal permeability, in preterm newborns to verify if a maturation pattern exists in preterm newborns during the(More)
BACKGROUND Paediatricians are familiar with infants complaining of regurgitation and emesis from gastrooesophageal reflux. These subjects, usually growing satisfactorily and healthy, are affected by "functional" or "symptomatic" gastrooesophagel reflux and are treated with posture changes and thickened feedings. AIM To evaluate in infants with symptomatic(More)
