This study addresses the effectiveness of a VR model that is designed to relieve distress and improve communication during pediatric dental treatment for 3-9 year-old young patients. This is due to the challenging nature of the dental treatment for both young patients and pediatric dentists. The proposed model is designed to alleviate the unpleasant experience a young patient might go through during the dental treatment through providing a VR content to be displayed in on a head-mounted device during the treatment session. In addition, the model is designed to help decrease the frequent movement of the young patient during the dental treatment session by directing the patient's head to the immersive VR content. Furthermore, the model could solve the communication difficulties that might occur between pediatric dentists and young patients during the treatment session by showing live instructions related to adjusting body postures

Currarino syndrome is a hereditary syndrome characterized by the triad of a sacral bony defect, presacral mass and anorectal malformation. We retrospectively reviewed 13 Currarino syndrome patients who were treated in our center between 1997 and 2010. Demographic data, initial symptoms, initial diagnosis. pathologic diagnosis of presacral mass, associated anomalies and managements were analyzed. There were 8 boys and 5 girls. Four patients were diagnosed as Currarino syndrome immediately after birth with failure of passage of meconium and abdominal distension. Four patients underwent surgery for imperforate anus immediately after birth and W8re diagnosed as Currarino syndrome later and underwent reoperation. Three patients were diagnosed during work-up and management with of the tentative diagnosis of Hirschsprung's disease. Diagnosis of the remaining two patients was at the age of 26 months and 9 years and anorectal malformation was not associated. Twelve patients showed hemi-sacrum and one patient showed bilateral sacral subtotal agenesis. Two patients without anorectal malformation underwent presacral mass excision, untethering of spinal cord and repair of myelomeningocele. Six out of 8 patients, excluding 3 that expired or were lost to follow up, with anorectal malformation underwent colostomy, presacral mass excision, untethering of spinal cord, repair of myelomeningocele, posterior sagittal anorectoplasty and colostomy repair. One patient underwent only posterior sagittal anorectoplasty after colostomy. One waits the scheduled operation only with Hegar dilatation. Pathologic examation of presacral masses showed myelomeningoceles in 4 patients, lipomyelomeningoceles in 3 patients and dermoid Cyst in one patient. Teratoma was combined in 2 patients. Eight patients needed neurosurgical operation for spinal cord problems. Seven patients had urologic anomalies and two of them underwent operation. Currarino syndrome should be considered as a differential diagnosis in pediatric patients with abdominal distension, constipation and anorectal malforlnation. For proper evaluation and treatment, a multi-disciplinary approach is recommended.

Condyloma acuminata, an uncommon disease m the pediatric patients, is being reported with increasing frequency in both adults and children. During the last 10 years, we managed 11 children with condyloma acuminata of the anogenital area. The patients' age at presentation varied from 9 months to 11 years, and boys outnumbered girls by a ratio of 2 : 1. The lesions were found in the perianal area in 9 patients and the genital area in 2. No history of sexual contact or abuse could be elicited. Although the exact mode of transmission of human papillomavirus(HPV) couldn't be defined, maternal-infant transmission at birth and close nonsexual family contact were the main possible causes of HPV infection in our patients. Our experience suggest that fulguration of the warts and concomitant excision with scissors of the larger lesions are the most satisfactory method of treatment in children. However, condyloma acuminata have high recurrence rate despite these treatments. Viral typing and careful epidemiological investigation on a larger series of patients may clarify the causative factors and effective modalities of treatment in childhood anogenital condyloma acuminata.

Purpose: Cholecystectomy is rarely performed in the child and adolescent. However, it is associated with several conditions. This study was conducted to describe the characteristics of pediatric patient who underwent cholecystectomy unrelated to hematologic disorders, and then to suggest its clinical significance in management by comparing a simple and complicated gallbladder disease. Methods: We reviewed cases of cholecystectomy in pediatric patients (under 18 years old) at a single institution between January 2003 and October 2014. There were 143 cases during the study period and 24 were selected as the subject group. Results: There were 7 male (29.2%) and 17 female (70.8%) patients. The mean age was 13.1 years old, and 66.6% of patients were older than 12 years. Mean body weight was 52.7 kg, and body mass index was $21.7kg/m^2$, with 41.7% of patients being overweight or obese. We could identify a female predominance and high proportion of overweight or obesity in a complicated disease. There were also significantly increased levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP) and bilirubin in this group. Most patients (87.5%) underwent laparoscopic cholecystectomy. Conclusion: Cholecystectomy for diseases unrelated to hematologic disorders is rarely performed in the child and adolescent. In general, female patients who are overweight or obese, and those older than 12 years old, require laparoscopic cholecystectomy owing to multiple gallstones. This condition has a tendency to show a complicated gallbladder disease and significantly increased levels of AST, ALT, ALP, and bilirubin.

Ventriculoperitoneal shunt(VP shunt) for hydrocephalus is thought to inhibit the closure of processus vaginalis and promote inguinal hernia by increasing intraabdominal pressure. To estimate the patency rate of processus vaginalis and the incidence and characteristics of the inguinal hernia, 262 cases of VP shunt in early childhood between January 1980 and May 1998 at Seoul National University Children Hospital were reviewed retrospectively. Inguinal hernia developed in 28 cases(10.7 %), but six patients had an inguinal hernia before the VP shunt was placed. Patients who had a VP shunt before 6 months of age developed inguinal hernia in 16.2 %(12/74) of cases, patients shunted between 6 months and 2 years had an incidence of 12.4 %(11/89) and only 5.1 %(5/99) of patients operated upon after 2 years of age developed hernias. Twenty-two patients out of 256 cases (8.6 %) developed inguinal hernia after VP shunt, with male predominance(M : F=4.5:1). Eight patients developed inguinal hernia bilaterally(36.4 %). It is suggested that at least 14% of processus vaginalis is patent until 2 years old.

Background: Sevoflurane, a rotatively new inhalational anesthetic. has non-pungent odor and is less reluctant to pediatric patients. The purpose of this study is to examine the feasibility of sevoflurane in inhalational sedation instead of the nitrous oxide for short and simple dental treatments in pediatric patients. Patients and Methods: Fifteen healthy children, whose dental treatment was abandoned due to their little or no cooperation, were selected with their caregivers' written permission. Deep sedation was induced and maintained with oxygen and 1-5% sevoflufane via specially designed nasal mask. Blood pressure, heart rate, oxygen saturation, and electrocardiogram were monitored at 3-nin interval. A dental anesthesiologist, who was independent of dental treatments, was wholly responsible for the sedation procedure. Post-sedation complications and operator's and caregiver's acceptability of this type of inhalational sedation were also investigated. Results: The systolic and diastolic blood pressure, heart rate, and oxygen saturation was significantly depressed during the deep sedation using sevoflurane (P < 0.05). No severe post-sedation complications were found, however, bradycardia was reported in 3 patients. Almost all the operators and caregivers answered that they would adapt this sedation procedure again if possible. Conclusion: In this study, inhalational deep sedation using sevoflurane for dental treatments was found to be very useful. Furthermore, the application of sevoflurane to conscious sedation for pediatric and adult dental patients should be added.

Pancreaticoduodenectomy is the treatment of choice for adult periampullary lesions. However there has been no studies on the clinical outcomes of pancreaticoduodenectomy in children. To evaluate the clinical outcomes, records of 13 patients who underwent pancreaticoduodenectomy, from 1989 to 2009, at Seoul National University Children's Hospital were reviewed. Mean follow up period was 83 (2-204) months, the male to female ratio was 1:3.3, and the mean age was 11 (2-14) years. Ten patients underwent PPPD and 3 patients had Whipple's operation. The postoperative diagnosis included solid pseudopapillary tumor (9), cavernous hemangioma (1), pseudocyst (1), benign cyst (1), pancreatic disruption (1). Two patients developed postoperative adhesive ileus and among them one patient required operative intervention. Four patients required pancreatin supplementation due to steatorrhea and other gastrointestinal symptoms. There were no postoperative mortality during the follow up period and no evidence of recurrence in SPT patients. This study demonstrates that the pancreaticoduodenectomy procedure in children is not only feasible but also safe, with no mortality and an acceptable complication rate.

Moyamoya disease (MMD) is the most common pediatric cerebrovascular disease in Far Eastern countries. In children, MMD frequently manifests as ischemic symptomatology. Cerebral perfusion gradually decreases as the disease progresses, which often leads to cerebral infarction. The benefits of revascularization surgery, whether direct or indirect, have been well established in MMD patients with ischemic symptoms. In adults, the increase in cerebral blood flow achieved with indirect revascularization is often unsatisfactory, and direct revascularization is usually feasible. In children, however, direct revascularization is frequently technically not feasible, whereas the response to indirect revascularization is excellent, although 1 or 2 weeks are required for stabilization of symptoms. The authors describe surgical procedures and perioperative care in indirect revascularization for MMD. In addition, special considerations with regard to very young patients, patients with recent cerebral infarction, and patients with hyperthyroidism are discussed.
