Multichannel intraesophageal impedance pattern of children with aerophagia
Bibliographic record
Abstract
BACKGROUND: Childhood aerophagia is defined by the Rome III criteria as two or more of the following symptoms; air swallowing, abdominal distension due to intraluminal air, or repetitive belching and/or flatus. The aim of this study was to determine the multichannel intraesophageal impedance (MII) pattern in children suffering from aerophagia. METHODS: We compared the MII tracings of five children with aerophagia according to Rome III criteria (three girls, median age 7 years) to five controls (three girls, median age 8 years). Controls underwent MII for symptoms of gastro-esophageal reflux, and had normal findings. Liquid swallows (LS), air swallows (AS), mixed swallows (MS) and supragastric belching (SGB) were recorded. Meals were excluded from the analysis. All MII parameters were separately analyzed in the upright and recumbent position. All data are reported as median number of events per hour. KEY RESULTS: There was no difference in the total number of LS and MS between the two groups. However, the total number of AS in patients was significantly higher than in controls (26/h vs 5.5/h, p < 0.05) but only in the upright position (46/h vs 8.2 in control group, p < 0.05). SGB was noted only in patients with aerophagia (2.6/h vs 0/h, p < 0.01). CONCLUSIONS & INFERENCES: Children suffering from aerophagia have a specific MII pattern with an increased frequency of air swallows in the upright position and supragastric belching. MII may be used as a tool to confirm diagnosis of aerophagia in children.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
