In this paper, a Working Group on Gastro-Oesophageal Reflux discusses recommendations for the first line diagnostic and therapeutic approach of gastro-oesophageal reflux disease in infants and children. All members of the Working Group agreed that infants with uncomplicated gastro-oesophageal reflux can be safely treated before performing (expensive and often unnecessary) complementary investigations. However, the latter are mandatory if symptoms persist despite appropriate treatment. Oesophageal pH monitoring of long duration (18-24 h) is recommended as the investigation technique of choice in infants and children with atypical presentations of gastro-oesophageal reflux. Upper gastro-intestinal endoscopy in a specialised centre is the technique of choice in infants and children presenting with symptoms suggestive of peptic oesophagitis. Prokinetics, still a relatively new drug family, have already obtained a definitive place in the treatment of gastro-oesophageal reflux disease in infants and children, especially if "non-drug" treatment (positional therapy, dietary recommendations, etc.) was unsuccessful. It was the aim of the Working Group to help the paediatrician with this consensus statement and guide-lines to establish a standardised management of gastro-oesophageal reflux disease in infants and children.

Aims-To investigate the eYcacy of chiropractic spinal manipulation in the management of infantile colic. Methods-One hundred infants with typical colicky pain were recruited to a randomised, blinded, placebo controlled clinical trial. Results-Nine infants were excluded because inclusion criteria were not met, and five dropped out, leaving 86 who completed the study. There was no significant eVect of chiropractic spinal manipulation. Thirty two of 46 infants in the treatment group (69.9%), and 24 of 40 in the control group (60.0%), showed some degree of improvement. Conclusion-Chiropractic spinal manipulation is no more eVective than placebo in the treatment of infantile colic. This study emphasises the need for placebo controlled and blinded studies when investigating alternative methods to treat unpredictable conditions such as infantile colic.

Olafsdottir E, Aksnes L, Fluge G, Berstad A. Faecal calprotectin levels in infants with infantile colic, healthy infants, children with in ammatory bowel disease, children with recurrent abdominal pain and healthy children. Acta Paediatr 2002; 91: 45-50. Stockholm. ISSN 0803-5253 This study investigated faecal calprotectin concentration, a measure of intestinal in ammation, in infants and children with abdominal pain. Faecal calprotectin was measured by an enzyme-linked immunosorbent assay kit in spot stool samples in 76 infants with typical infantile colic, 7 infants with transient lactose intolerance and 27 healthy infants. All infants were 2-10 wk of age. In addition, 19 children with recurrent abdominal pain (RAP; mean age 11.5 y), 17 with in ammatory bowel disease (IBD; mean age 11.1 y; 10 had Crohn's disease and 7 ulcerative colitis) and 24 healthy children (mean age 5.3 y) were studied. In infants with infantile colic the mean faecal calprotectin concentration was not different from that in healthy infants (278 § 105 vs 277 § 109 mg kg ¡1 , p = 0.97) or in infants with transient lactose intolerance (300.3 § 124 mg kg ¡ 1 , p = 0.60). The calprotectin level was similar in boys and girls and fell signi cantly with age (p = 0.04). Children with IBD had faecal calprotectin levels (293 § 218 mg kg ¡1 ) much higher than healthy children (40 § 28 mg kg ¡1 , p < 0.0001) and children with RAP without identi ed organic disease (18 § 24 mg kg ¡1 , p < 0.0001).Conclusion: Faecal calprotectin may differentiate between functional abdominal pain and IBD in school-aged children. In young infants high faecal calprotectin levels are normal.

Background and aims: Our aim was to study intragastric volume and distribution of a liquid meal in patients with reflux oesophagitis using three dimensional ultrasonography. Methods: Twenty patients and 20 healthy controls underwent ultrasonographic measurements of the stomach using a position sensor based on magnetic scanhead tracking for acquisition of three dimensional images. In vivo accuracy of the method was evaluated by scanning a soup filled barostat bag positioned in the proximal stomach of six healthy subjects. Results: In the volume range 100-700 ml, our three dimensional system showed excellent correlation (r=0.99) between estimated and true volumes (limits of agreement −3.4 to 11.0 ml) and a low interobserver variation (limits of agreement −10.9 to 6.7 ml). After ingestion of a 500 ml meat soup meal, patients with reflux oesophagitis revealed a larger volume of the total and proximal stomach at two and 10 minutes (p=0.05; p=0.01, respectively), and an increased proximal/distal intragastric volume ratio at 10 minutes (p=0.04). Patients also experienced more epigastric fullness than controls (p=0.0006).Conclusions: The present three dimensional ultrasound system showed excellent agreement with true volumes and low interobserver variation. Soon after a liquid meal, patients with reflux oesophagitis have abnormal pooling of the ingested liquid in the proximal stomach.
