Relevance of CagA positivity to clinical course of Helicobacter pylori infection in children.

A potential virulence determinant of Helicobacter pylori is the cagA gene product. To determine the relevance of the expression of CagA to the clinical picture and outcome of H. pylori infection in children, we examined 104 consecutive children diagnosed with H.

The value of anti-Helicobacter pylori IgG antibodies in establishing eradication of infection in children.

The aim of this study was to evaluate the performance of anti-Helicobacter pylori (H. pylori) IgG antibodies in monitoring eradication of infection in children. Forty-seven H.

A lamb-meat-based formula for infants allergic to casein hydrolysate formulas.

Ten infants with colitis due to milk protein allergy, presenting as hematochezia, whose symptoms did not resolve with the use of hydrolyzed cow-milk-based formulas, were treated with a modular lamb-meat-based formula (LOP). The patients were followed up for 3 months to 5 years. Prompt resolution of symptoms was achieved.

Basal and meal-stimulated pepsinogen secretion in preterm infants: a longitudinal study.

In order to establish longitudinal normal values for basal and meal-stimulated pepsinogen secretory function in preterm infants, we studied 44 preterm infants with gestational ages of 28-36 weeks during the period of nasogastric tube feeding. Three age groups were evaluated: gestational ages of 28-30, 31-33, and 34-36 weeks. Basal pepsinogen did not change with postnatal age in any of the groups.

Aplastic anaemia complicating adenovirus infection in DiGeorge syndrome.

An 18-month-old child with partial DiGeorge syndrome developed aplastic anaemia during an acute adenovirus infection. Assessment of the child's immune system revealed T-cell subset abnormalities consistent with DiGeorge syndrome. A possible link between the underlying immune deficiency and the observed complication is suggested.

An unusual presentation of pancreatic carcinoma in childhood.

Carcinoma of the pancreas is rare in the pediatric population, with only 58 cases described in subjects under 16 years of age. The clinical presentation generally consists of abdominal pain and mass. We present a case of carcinoma of the pancreas in an 11-year-old girl, with abdominal pain and unusual behavior.

Partial duplication of the lower limb with agenesis of ipsilateral kidney--a new syndrome: report of a case and review of the literature.

A detailed account is given of a 19-month-old female infant with partial duplication of the left lower limb and aplasia of the ipsilateral kidney, plus other congenital malformations. Although the etiology is unknown, we believe this constellation of findings, which has been reported previously, represents a new congenital malformation syndrome.
