An 1-month old female newborn was admitted to our hospital because of jaundice which occurred at 2 days after birth. Plain chest X-ray and chest CT revealed a collapsed right middle lobe and lobar emphysema was suspected. Right upper lobectomy of the lung was done and pathologic findings showed an infantile lobar emphysema. After the operation, the newborn was discharged without complication and was followed up through the out patient clinic. Infantile lobar emphysema is rare and male dominant. Left upper lobe of the lung is the most prevalent site. Patients with infantile lobar emphysema complain of respiratory symptoms. We report one case of infantile lobar emphysema on right upper lobe of lung, in a female with no respiratory symptoms.

A fecaloma refers to a mass of accumulated feces that is much harder than a mass associated with fecal impaction. Fecalomas are usually found in the rectosigmoid area. A 10-year-old male with chronic constipation was admitted because of increasing abdominal pain. An abdominal computed tomography scan and a simple abdominal x-ray revealed rapidly evolving mechanical obstruction in the small intestine. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, surgical intervention may be needed. In this case, an emergency operation was performed and a $4{\times}3{\times}2.5cm$ fecaloma was found in the distal ileum. We thus report a case of ileal fecaloma inducing small bowel obstruction in a patient with chronic constipation, who required surgical intervention. When symptoms of acute small intestinal obstruction develop in a patient with chronic constipation, a fecaloma should be considered in differential diagnosis.

Hemolytic anemia due to cold agglutinin disease is a known complication of Mycoplasma pneumoniae infection but is rarely observed, particularly in children. A case of Mycoplasma pneumonia complicated with hemolytic anemia is presented. A 7 year-old girl was adimitted because of fever, cough, sputum and pale appearance. Chest X-ray showed pneumonic consolidation of Rt. upper lobe, lingular division. Laboratory studies disclosed the following values : Hb 5.3g/dL, Hct 11.1%, reticulocyte 2.9%, indirect Coombs test negative, direct Coombs test(monovalent) Anti-C3d positive, Anti-IgG negative, Anti-IgM negative, cold agglutinin titer 1 : 256, mycoplasma antibody titer 1 : 640, total bilirubin 1.0mg/dL. Initial PBS before wanning showed agglutination of red blood cells. The diagnosis of cold agglutinin hemolytic anemia complicating mycoplasma pneumonia was made. And treatment with roxithromycin, prednisolone and avoiding cold exposure was initiated, and complete recovery ensued. We report a case of cold agglutinin hemolytic anemia complicating mycoplasma pneumonia in children.

Myocarditis refers to inflammation, necrosis, or myocytolysis that may be due to many infectious, connective tissue and many other causes affecting the myocardium or involvement of the endocardium or pericardium. The most common manifestation is congestive heart failure, although arrhythmias and sudden death may be the first sign of myocarditis. Viral myocarditis is typically a sporadic but occasionally epidemic illness, noted as an acute potentially fulminant disease of 1-to 4-wk-old infants, as an acute but more benign myopericarditis of toddlers and young children. The most common casuative agent in viral myocarditis is Coxsackievirus and the outcome of the biopsy-proven chronic dilated cardiomyopathy associated with Coxsackievirus is poor without therapy. Myocarditis may be confirmed by percutaneous endomyocardial biopsy and the viral myocarditis may be diagnosed by the serological viral study with the clinical manifestations. He was admitted for the management of tachyarrhythmias occurred suddenly without prodromal symptoms and signs and diagnosed as viral pancarditis by serological Coxsackievirus study, echocardiogram, chest x-ray, EKG and other clinical manifestations.

We experienced a case of Henoch-Sch$\ddot{o}$nlein purpura associated with Mycoplasma pneumoniae pneumonia in a 28 month old male who suffered from cough, abdominal pain and both leg swelling and pain. Physical examination showed varying sized purpura, characteristic of Henoch-Sch$\ddot{o}$nlein purpura, below both knee. Laboratory test revealed Mycoplasma pneumoniae antibody titer >1:2,560 and cold agglutinins titer 1:64. Chest X-ray showed peribronchial blurring in both lung fields. The patient was treated with midecamycin and prednisolone for 7 days and responded to the treatment well. The authors report a case of Henoch-Sch$\ddot{o}$nlein purpura with Mycoplasma pneumoniae pneumonia with brief review of related literatures.

Purpose : Lower respiratory tract infections in infant and young children are often due to a virus, especially the Respiratory syncytial(RS) virus. Chest X-ray findings in bronchiolitis and bronchopneumonia are different. The radiographic hallmark of bronchiolitis is pulmonary hyperinflation and similar to that of bronchial asthma. Bronchiolitis is predisposed to later development of bronchial asthma. To evaluate the difference of immuno-pathophysiology between bronchiolitis and bronchopneumonia, we measured $IFN-{\gamma}$(Th1 cytokine), IL-5(Th2 cytokine) and ECP. We also investigated whether X-ray findings in infants with viral infected respiratory disease are useful in predicting the development of asthma. Methods : We measured IL-5, ECP, $IFN-{\gamma}$ levels in serum from 21 infants with bronchiolitis and 21 infants with bronchopneumonia and 16 infants without pulmonary viral diseases. Results : IL-5 levels of bronchiolitis and bronchopneumonia were significantly higher than those of the control(P=0.02, P=0.042). IL-5 levels of bronchiolitis were higher than those of bronchopneumonia but there was no significant difference. $IFN-{\gamma}$ levels of bronchopneumonia were higher than those of bronchiolitis but there was no significant difference. ECP levels of bronchiolitis and bronchopneumonia were higher than those of the control but only those of bronchiolitis were significantly higher than those of the control(P=0.045). IL-5 and ECP levels did not show any significant correlation in bronchiolitis, bronchopneumonia and control groups. Conclusion : We cannot prove the distinct differences in serum Th1/Th2 cytokine profiles between bronchiolitis and bronchopneumonia in infants. These results suggest that the different findings on chest X-ray between bronchiolitis and bronchopneumonia could not be a predictor of later development of asthma.

Sigmoid volvulus may cause acute or subacute colonic obstruction. Excessive length of the sigmoid colon may be a contributing factor. Typically, the patient develops bilious vomiting and marked gaseous abdominal distension. We report a case of sigmoid volvulus in a 9-year-old boy who presented with recurrent, sudden onset abdominal pain, abdominal distension, and vomiting for 1 year, which was diagnosed by simple abdominal X-ray, barium enema, computed tomography, and colonoscopic examination. Colonoscopic reduction failed and a sigmoid colectomy with primary repair was performed. The intra-operative findings showed that the sigmoid colon was noted to be dilated, and redundant with a lax mesentery. Two clear areas of compression (proximal and distal) were present. After sigmoidectomy, the symptoms resolved. After 5 years of follow-up, he had no new symptoms.

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.

Intestinal obstruction is not uncommon in infants. The common causes of intestinal obstruction in the neonatal period are Hirschsprung disease, intestinal atresia, meconium ileus, and intussusception. However, small bowel obstruction caused by a congenital band is very rare. We report a 27-day-old baby who was admitted with abdominal distension and fever. The abdominal X-ray revealed massive bowel dilatation and the contrast gastrografin enema suggested a distal small bowel obstruction. The explolaparotomy showed small bowel entrapment due to an unusual anomalous congenital band.

Transcatheter closure of atrial septal defects has become a popular procedure. The availability of a preprocedural imaging study is crucial for a safe and successful closure. Both the anatomy and morphology of the defect should be precisely evaluated before the procedure. Three-dimensional (3D) echocardiography and cardiac computed tomography are helpful for understanding the morphology of a defect, which is important because different defect morphologies could variously impact the results. During the procedure, real-time 3D echocardiography can be used to guide an accurate closure. The safety and efficiency of transcatheter closures of atrial septal defects could be improved through the use of detailed imaging studies.
