Purpose: Children with esophagitis express a variety of nonspecific symptoms and signs depending on their age, and diagnosis is limited because gastrointestinal endoscopy (GFS) and biopsy are difficult to perform. The aim of this study was to examine the prevalence of esophagitis in children with upper abdominal pain, to determine the necessity of esophageal biopsy, and to evaluate the associated risk factors. Methods: We reviewed 266 pediatric patients with upper abdominal pain who underwent history-taking, physical examination, and GFS with esophageal and gastric biopsies between January 2006 and December 2007. Esophagitis was confirmed on biopsy. We analyzed the risk factors for histologic esophagitis and the necessity of esophageal biopsy. Results: The prevalence of esophagitis was 19.9% (53/266 patients). The sensitivity and specificity of endoscopic diagnosis were 41.5% and 77%. Of 53 patients with histologic esophagitis, reflux esophagitis was seen in 50 patients, eosinophilic esophagitis was seen in 2 patients, and esophageal candidiasis was seen in 1 patient. Vomiting was a significant factor in patients under 8 yr of age (p<0.05). H. pylori infection was documented in 41.5% of patients with histologic esophagitis, compared with 58.5% of patients not infected with H. pylori (p<0.05). The possibility of histologic esophagitis was higher in patients with H. pylori infection (OR 2.5, 95% CI 1.2544 to 4.8286) and in those who visited in the spring (OR 2.5, 95% CI 1.2544 to 4.8286). Conclusion: We believe esophageal tissue biopsy should be performed in pediatric patients with upper gastrointestinal symptoms who are undergoing GFS and stomach tissue biopsy, especially preschoolers and H. pylori-infected children in the spring.

Eosinophilic gastroenteritis is a rare clinicopathologic entity of unknown etiology with a variety of digestive symptoms. The pathogenesis is poorly understood. Diagnostic criteria include demonstration of eosinophilic infiltration of the affected bowel wall, lack of evidence of extraintestinal disease, and exclusion of various disorders that could mimic similar conditions. The disease might involve any area of the gastrointestinal tract from the esophagus to the rectum, but the stomach and the proximal small bowel are most commonly affected. The clinical features depend on which layer and site are involved. We report the case of a 59-year-old male patient with a 3-week history of post-prandial vomiting with malnutrition and weight loss. An abdominopelvic CT showed a gastric outlet obstruction with diffuse wall thickening, as with linitis plastica. Three gastrofiberscopic biopsies showed chronic gastritis. We carried out a radical total gastrectomy with D2 lymph node dissection. The pathologic report revealed a mural type eosinophilic gastritis with a marked hypertrophic scar formation at the proper muscle layer. We report this case with a brief review of the literature.

Background: The purpose of this study was to examine the causes and pathologic process of chronic non-productive cough as an isolated symptom with a normal spirometry and chest radiograph by investigating clinicopathologic findings. Method: We studied 25 adults with chronic non-productive cough over a 3-week period with a normal chest radiograph and pulmonary function tests without any other symptoms. Clinical assessment, cough score, chest and sinus radiograph, pulmonary function tests, methacholine challenge, allergic skin prick test, and bronchoscopy for bronchial biopsies were performed. Subjects were then treated with prednesolone 20 to 30 mg/day for 1 to 2 weeks. Results: The experimental group was divided into two subgroups-those infiltrated with eosinophils, and those infiltrated with lymphocytes depending on eosinophil and lymphocyte counts, both of which were respectively higher than those of the control group. Eosinophils infiltrated group had mean numbers of eosinophil of 89.8 $cells/mm^3$ while control group's mean was 0.4 $cells/mm^2$(p=0.005). Lymphocyte infiltrated group was 4 patients whose mean was 84.3 $cells/mm^2$ with 28.4 $cells/mm^2$ of control group(P=0.026). In addition, the mean thickness of the basement membrane of experimental group was $14.20{\pm}5.20{\mu}m$ in contrast of control group whose mean was $3.50{\pm}1.37{\mu}m$(P=0.001). With the methacholine challenge test, 7 of the 21 eosinophil infiltrated subjects were diagnosed with cough variant asthma ; the other 14 with eosinophilic bronchitis. Three subjects with eosinophilic bronchitis were atopic positive (21.4%) with the skin prick test In the lymphocyte dominant group, all four subjects were diagnosed with lymphocytic bronchitis. Cough score was improved after steroid treatment in 22 of 25 subjects in the experimental group (88.0%). Conclusion: These results suggest chronic non-productive cough as an isolated symptom with a normal spirometry and chest radiograph was associated with airway inflammation by eosinophil and lymphocyte infiltration. The causes for chronic non-productive cough were eosinophilic bronchitis, cough variant asthma, and lymphocytic bronchitis(written in frequency). They further suggest that therapeutic treatment with steroids can provide effective symptomatic relief.

Purpose: A new classification of gastrointestinal food allergy was published, but the changes of terminology between previously reported terms and the new ones were in a state of disorder. This has resulted in confusion between medical communication and diagnostic and therapeutic approaches. The clinical observations of infants presenting with gastrointestinal cow milk allergy (GI-CMA) were performed, and the changes in the terminology reviewed through the published Korean literature. Methods: Between March 2003 and July 2003, data from 37 consecutive infants with GI-CMA, aged 2 weeks to 15 months, were reviewed. The challenge and elimination test of cow milk, and the endoscopic and histologic findings, were used for the seven subdivisions of GI-CMA according to a new classification on the basis of patients' ages, clinical manifestations and location of gastrointestinal lesions. Results: The 37 patients had a mean age of $5.4{\pm}4.8$ months, with those observed in 26 (70.3%) of patients being below 6 months of age. The seven final diagnoses were; cow milk protein-induced enterocolitis (CMPIE) in 12 (32.4%), cow milk protein proctitis (PROC) in 12 (32.4%), IgE-mediated (IGE) in 6 (16.2%), gastroesophageal reflux-associated cow milk allergy (GERA) in 5 (13.5%) and eosinophilic gastroenterocolitis in 2 (5.4%). CMPIE was revealed as the typical type in 7 (18.9%) and the atypical type in 5 (13.5%), and all of typical CMPIE revealed cow milk protein-induced enteropathy. The mean age at symptom onset was $4.3{\pm}0.8$ months, and for those with typical and atypical CMPIE, and PROC and GERA were $3.8{\pm}4.6$, $10.4{\pm}3.8$, $3.4{\pm}3.9$ and $7.8{\pm}5.7$ months, respectively (p<0.05). The period from onset of symptom to diagnosis was $2.4{\pm}3.3$ (0.5~12) months, with those observed in atypical CMPIE and GERA being over 3months. Although the birth weights in all patients were within the 10~90 percentile range, the body weights on diagnoses were below the 3 percentile in 48.6%; IGE 16.7%, EOS 0%, typical CMPIE 85.7%, atypical CMPIE 60.0%, PROC 25.0% and GERA 100% (p<0.05). Through the review of the Korean literature, 8 case reports and 14 original articles for GI-CMA were found. Conclusion: GI-CMA is not a rare clinical disorder and is subdivided into seven categories on the basis of the patient's age, clinical manifestations and location of the gastrointestinal lesions. The terms for GI-CMA are changing with new classifications, and careful approaches are necessary for medical communications.
