A Follow-Up Study of Cow's Milk-Sensitive Enteropathy: Clinical Outcome / 대한소아소화기영양학회지

PURPOSE: Following up the cases of cow's milk-sensitive enteropathy (CMSE), We observed the development of clinical tolerance with cow's milk and other foods. We investigated the clinical outcome of CMSE. METHODS: We reviewed the clinical records of patients who had been admitted and diagnosed as CMSE by responses to cow's milk challenge and elimination test and the findings of small intestinal biopsy at Department of Pediatrics, Taegu Catholic University Hospital from March 1992 to March 1997. All of them were being fed with protein hydrolysate before 6 months old, and tried cow's milk and other foods challenge test at following each two month. Twenty-one cases of them returned to be followed. The age at admission was 30.7+/-8.8 (18~47) days old and at survey was 43.4+/-23.7 (16~84) months old. RESULTS: 1) Although the body weight at birth of the patients was 25~75 percentile, all on admission was below 3 percentile. The body weight on interview was 25~75 percentile. 2) The development of clinical tolerance in cow's milk was observed at 16~24 months of age and the tolerance rate was 61% at 12 months of age, 90% at 16 months of age. The development of clinical tolerance in other foods was observed at 10~24 months of age and the tolerance rate was 33% at 12 months of age, 80% at 18 months of age. 3) Adverse reactions after challenge test with cow's milk were observed at 19 cases, manifestated as vomiting (31%), diarrhea (31%), irritability or lethargy (21%), skin rash (10%), and abdominal distention (5%). 4) Comparing serum IgE and milk RAST positive group on admission (5 cases) and negative group on admission (16 cases), there was no significant difference at the age of tolerance in cow's milk (p>0.05), the age of tolerance in other foods (p>0.05), allergy history in family, and the incidence of other allergic diseases. 5) The history of family allergy was observed in 3 cases (14%) in 21 patients and 3 cases (14%) showed rhinitis, urticaria or asthma through a follow-up interview. CONCLUSION: The development of clinical tolerance in cow's and other foods was sharply increased at 12 months of age and most of all tolerated within 24 months of age. CMSE is a temporary disorder of infancy.

A Case of Pathologic Aerophagia with Mental Retardation Managed by Percutaneous Endoscopic Gastrostomy / 대한소아소화기영양학회지

We experienced a case of pathologic aerophagia in a 10-year-old girl who has mental retardation. It was observed that the abdomen was non-distended in the morning and became maximally distended in the evening. Increased passage of flatus, but normal eructation, was noted. Roentgenographic examination showed 'esophageal air sign', abnormal air shadow on proximal esophagus adjacent to the trachea, in simple chest X-ray and visible air swallowing fluoroscopically. We tried a percutaneous endoscopic gastrostomy (PEG) to decompress swallowed air in stomach. We suggest that placement of a PEG catheter in early life, especially in mentally retarded patients, that can be used as desufflator, can prevent the complications of aerophagia. 'Esophageal air sign' may be very helpful for early detection of pathologic aerophagia.
