Anomalous origin of right coronary artery from pulmonary artery is a rare congenital cardiac anomaly. Anomalous right coronary artery often be a incidental finding without serious cardiovascular sequale. The only characteristic physical finding is a continuous murmur with diastolic accentuation. There are no diagnostic EKG or chest X-ray changes. Diagnosis is made best by selective left coronary arteriography showing retrograde filling of right coronary artery from collateral vessels. Here, we present a case of twenty-four months old aged girl with anomalous origin of right coronary artery combined with pulmonary stenosis. This is the first pediatric patient with anomalous right coronary artery and the first patient to have surgical correction for this malformation.

Bone age assessment has been widely used to measure the ossification in pediatric radiology. For the assessment, first bone age of each epiphyseal plate is estimated using DCT/LDA, then the bone age of a patient is calculated by using the median of 9 estimations. For some patients, however, due to various reasons such as X-ray image quality or the pose of fingers, it is common to miss couple of plates in automated systems. In this paper, we investigate the relationship between the number of detected plates and the accuracy of bone age assessment. In the experimental results, we confirmed the similarity between bone age assessed using more than 7 epiphyseal plates and that assessed using 9 epiphyseal plates.

Colonic atresia (CA) is the rare cause of intestinal obstruction, and diagnosis of CA is difficult. But only few research has been performed, so little information has been available. The purposes of this study was to analyze the clinical findings of CA so that help physicians make decision properly. Children with CA who were treated at the division of pediatric surgery at Asan Medical Center in the period from January 1989 to December 2011 were evaluated retrospectively. A total of 6 children were treated with CA. These accounted for 2.7% of all gastrointestinal atresias managed in Asan Medical Center. Only one child was premature and low birth weight, the others were fullterm neonates and showed normal birth weight. Vomiting and abdominal distension were common symptoms and simple X-ray and barium study were used for diagnose of CA. But only 66.7% of the babies were diagnosed as CA pre-operatively. And 2 children out of 6 underwent re-operation due to missed CA at the time of the first operation. In aspect of types of atresia, the type IIIa were two, type IV were two, type I was one case, and one child showed rectal stenosis due to rectal web. Various operations were done according to individual findings and associated diseases. The 50% (n=3) of children underwent the primary anastomosis and the others (n=3) underwent colostomy first and staged operation later for missed CA or associated disease. All of them were recovered any significant complications. Therefore, the prognosis of CA is satisfactory if diagnosis and surgical management could be made properly. But because of the low incidence of CA, delay of diagnosis and treatment may occur. To prevent delay of diagnosis, we suggest prompt evaluation of doubtful infant and careful inspection of distal patency of bowel including whole colon and rectum when operating patients with intestinal atresia at any level.

Respiratory syncytial virus (RSV) is the major cause of lower respiratory tract infection in infants. Life-threatening RSV infection is often reported in young children and immunocompromised hosts. Since there is no report on ribavirin therapy for RSV pneumonia in pediatric cancer patients in Korea, we report one case of RSV pneumonia that developed in an infant with acute lymphoblastic leukemia (ALL). Despite administration of oral ribavirin and intravenous immunoglobulin, the patient's respiratory distress worsened and admission to an intensive care unit was necessary. Chest x-ray showed multifocal consolidation, pneumothorax, and pneumomediastinum. Treatment with aerosolized ribavirin led to significant clinical improvement. The role of aerosolized ribavirin is still controversial, but it might have a therapeutic potential for severe RSV pneumonia in children with leukemia.

Aspiration of tooth can occur not only during dental treatment, but also due to factors like trauma or physiologic exfoliation of primary tooth. If this occurs, complications such as fever, cough, dyspnea, pain, and bronchitis can be appeared. 9 years-old girl with Lennox-Gastau syndrome visited the dental clinic for regular checkups. Calcified tooth-like material was observed in the chest PA x-ray, and maxillary left primary first molar was not observed in the patient's oral cavity. She had a history of hospitalization for pneumonia two months ago. Because it was considered that the tooth was likely to be aspirated and caused pneumonia, the extraction of remaining primary teeth with mobility was performed. It is necessary to reduce the risk of aspiration in patient with disabilities by performing active treatment such as removal of primary tooth with mobility or ill-fitting restorations.

An 8-year-old boy presented with abdominal pain and poor oral intake for two months. Serum amylase and lipase levels were elevated. CT of the abdomen and chest X-ray showed two pseudocysts at the pancreatic uncinate process, pancreatitis with a parenchymal defect, a large amount of ascites, and a right pleural effusion. MR cholangiography and endoscopic retrograde cholangiopanreaticography revealed a pancreatic duct disruption. The patient was successfully treated with a chest tube placement and percutaneous drainage. After surgery, his general condition improved; the serum level of amylase normalized and the pleural effusion resolved. Pancreatic injuries are rare in pediatric blunt trauma; however, diagnostic difficulty is common with isolated blunt trauma. Therefore, a high index of suspicion should follow such an injury. We report the case of an 8-year-old boy with pancreas transection, ductal disruption, ascites, and pleural effusion who was successfully treated.

Objectives : The purpose of this study was to investigate the treatment trend for allergic rhinitis in Korean Medicine. Methods : We conducted an online survey for Korean Medicine Doctors who were registered in the association of Korean Medicine. The questionnaire was consisted of patient characteristics, diagnosis status, treatment status, and future research needs. Results : Data from total of 396 respondents were analyzed. More than 70% of the patient came to the Korean Medicine Clinic after visiting the Western Medicine Clinic in 43.9% of the respondents. 55.6% of the respondents performed combination therapy. History taking, nasal examination, x-ray, and Korean Medicine diagnostic test were used for diagnosis. The mean duration of treatment ranged from $4.9{\pm}2.91$ to $15.2{\pm}8.45$ for pediatric and early childhood patients and from $17.5{\pm}16.15$ to $5.3{\pm}3.85$ weeks for adolescents and adult patients. The mean number of treatment times was from $9.8{\pm}7.00$ to $33.5{\pm}24.45$ for pediatric and early childhood patients and from $10.8{\pm}11.55$ to $40.4{\pm}48.18$ times for adolescents and adult patients. 64.5%, 48.0%, and 91.2% of the respondents used herbal medication in national health insurance coverage, herbal medication uninsured in health insurance and herbal prescription filled at each medical institution, respectively for pediatric and early childhood patients and 67.6%, 42.8% and 86.1% for adolescents and adult patients. 36.9% and 36.4% of respondents answered that the study of acupuncture and herbal medicine are needed preferentially. Conclusions : The results of this survey will be used to develop clinical practice guideline that reflect actual clinical practice.

Lateral eyebrow mass with primary skull lesion are rare in pediatric population. Although epidermoid cyst and dermoid cyst are the most commonly encountered skull lesions in pediatric population, Langerhans cell histiocytosis (LCH) is rarely reported. We report a case of LCH arising from the lateral eyebrow with osteolytic lesion involving the frontal bone. A 5-year-old boy was presented with a hard, fixed mass in his lateral eyebrow. Contrast magnetic resonance imaging revealed inhomogeneous enhancement of the mass with direct invasion of the frontal bone and adjacent dura mater. Under general anesthesia, linear incision at the lateral eyebrow region was made. Intraoperative evaluation revealed hard, fixed and well-defined soft tissue mass. The final extirpated mass was $2.5{\times}2.4cm$ in size, and was accompanied by a $1{\times}1cm$ sized defect on the frontal bone with intact dura mater. The surgical wound was closed primarily by a layer-by-layer fashion. Histologic examination was later performed for definite diagnosis. The histologic examination revealed abnormal proliferation of Langerhans cell with granuloma formation. Radionuclide bone scan and positron emission tomography was taken and revealed free of multi-organ involvement. At 3 months after surgery, natural looking contour at the lateral eyebrow region was observed with no tumor recurrence. Differential diagnosis of the hard and fixed mass at the lateral eyebrow region affecting the primary skull lesion from pediatric population includes epidermoid cyst, dermoid cyst and LCH. Generally, brief physical examination with plain X-ray view can be performed for clinical evaluation, but for a definite diagnosis, contrast MRI may be helpful.

Additional dentition images are needed because the dentitions are distorted in cone-beam computed tomography (CBCT) due to streak artifacts and non-uniformity of the x-ray beam. The purpose of this study is to evaluate the feasibility of improving the dentition image of CBCT scan with intraoral scanner instead of plaster models. Maxilla images from plaster models, two intraoral scanners, and CBCT of 20 patients aged 12 to 18 were used in this study. With one of the intraoral scanners, the full arch was scanned by three segments and combined into a complete full arch. Virtual skull-dentition hybrid images from intraoral scanners were superimposed with the images from plaster models to evaluate the coordinate value difference and distance at reference points. The results showed that the coordinate value difference and distance were smallest with segmented intraoral scan, which showed only 2 ㎛ distance. Intraoral scan may provide good dentition images for virtual skull-dentition images.

Propose : Body composition by bioelectrical impedance analysis(BIA) is a very useful method of analysing body composition. BIA is non-invasive, inexpensive, nonhazaedous and reproducible technique. The aim of this study was to determine the level of agreement between body composition measurement by BIA and dual-energy X-ray absorptiometry(DEXA). Methods : Data was examined in 100 children(male 58; female 42), who visited Pusan National Hospital. Weight(kg) and height(cm) were measured, and body compositions were analyzed with fat mass, lean body mass, body fat percent by BIA and DEXA methods. Results : Comparison of the DEXA and BIA methods showed highly statistically significant correlations in measurement of human body composition(fat mass, lean body mass, body fat percent). Conclusion : BIA should be considered as the method of choice in measurement of human body composition, since it's non-invasive, reliable, rapid, nonhazaedous and inexpensive, using portable equipment.
