Susceptibility to recurrent abdominal pain, allergic and psychological disorders in childhood may be increased by infantile colic. Our findings confirm that severe infantile colic might be the early expression of some of the most common disorders in childhood.

Aim: To evaluate the association between infantile colic and gastrointestinal, allergic and psychological disorders in childhood. Methods: A prospective study was conducted on 103 infants aged 31–87 d. After 10 y, between 2001 and 2003, the children were recalled and a paediatrician evaluated the selected disorders by anamnesis, medical examination, laboratory tests and parent interviews. Results: Of the 103 infants enrolled, 96 completed the study. There was an association between infantile colic and recurrent abdominal pain (p=0.001) and allergic disorders: allergic rhinitis, conjunctivitis, asthmatic bronchitis, pollenosis, atopic eczema and food allergy (p<0.05). Sleep disorders, fussiness, aggressiveness and feelings of supremacy are more frequent in children who suffered from colic during early infancy (p<0.05). A family history of gastrointestinal diseases and atopic diseases was significantly higher in infants with colic than in controls (p<0.05). Conclusion: Susceptibility to recurrent abdominal pain, allergic and psychological disorders in childhood may be increased by infantile colic. Our findings confirm that severe infantile colic might be the early expression of some of the most common disorders in childhood.

The pathogenesis of gastro-oesophageal reflux disease (GORD) is complex and multifactorial. A motility disorder resulting from immaturity of the gastro-oesophageal tract may be involved. We have combined multichannel intraluminal impedance (MII) and pH monitoring with epigastric impedance (EGI) to evaluate the activity of this tract in neonates with suspected GORD. Multichannel intraluminal impedance, pH and EGI were followed for 3 h in 30 newborns displaying apparent life-threatening events and signs of GORD. Simultaneous application of MII and pH monitoring identifies reflux episodes and illustrates their duration, height and pH. Episodes detected by MII were placed on the EGI curve and the contemporaneous gastric filling state and emptying velocity were calculated. During the total measuring time, 248 reflux episodes were revealed. An inverse correlation was evident for reflux frequency and gastric emptying velocity (r2 = 0.94; P < 0.001), and between acid refluxes and the gastric filling state (r2 = 0.95; P < 0.001), whereas a positive correlation was found between the reflux level and the gastric filling state (r2 = 0.52; P < 0.05). Simultaneous MII, pH and EGI monitoring provided new information on the relationship between refluxes and gastric activity. Data suggest that gastric emptying patterns influence the frequency, level and pH of reflux episodes.
