Crohn's disease (CD) is a chronic, incurable and relapsing disease involving any part of the gastrointestinal tract and exclusive enteral nutrition (EEN) is first-line therapy. Few studies have examined the patient experience of EEN. The aim of this study was to assess the child's experiences of EEN, to identify problematic themes and understand the child's mindset. Children with CD who previously completed EEN were recruited to complete a survey. All data were analyzed using Microsoft Excel and reported as N (%). Forty-four children (mean age 11.3 years) consented to participate. Sixty-eight percent of children reported limited formula flavors as the most challenging aspect and 68% of children identified 'support' to be important. This study highlights the psychological impact of chronic disease and its therapies on children. Providing adequate support is essential to insure EEN is successful. Further studies are required to determine psychological support strategies for children taking EEN.

Stevens-Johnson syndrome (SJS) is a severe adverse cutaneous drug reaction seen rarely in clinical practice. Although relatively rare, the condition can be fatal. Mainly, it is caused by side effects of certain medications. Previous reports have associated Stevens-Johnson syndrome with abnormal root development, but the other long-term dental complications have rarely been reported. In this case, the patient developed SJS at the age of 5, and abnormal root development of the maxillary and mandibular first molars and mandibular incisors was observed, as well as impaction of the mandibular canine and enamel hypomineralization of multiple teeth. Accordingly, appropriate restorative treatment and orthodontic treatment were performed, and the clinical characteristics of this symptoms and its treatment were discussed in more detail. We aim to highlight the need for dentists to be aware of the potential dental complications of SJS and to enable early diagnosis and management of the condition to avoid undesirable sequelae.

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.

Purpose: This study aimed to examine the changes in the outbreak of acute gastroenteritis, rotavirus gastroenteritis after the introduction of the rotavirus vaccine in Korea. Methods: The current study investigated the number of inpatients in the pediatric ward of Inje University Sanggye Paik Hospital during the periods of 2005-2006 and 2011-2012. A retrospective analysis was conducted on the medical records of 2,840 patients <5 years of age who were hospitalized at Inje University Sanggye Paik Hospital in these time periods. Results: When we compared 2 separate sets of data from before (2005-2006) and after (2011-2012) vaccine introduction, there were statistically significant decreases in the number of patients who were hospitalized for acute gastroenteritis across all of the groups of patients <5 years of age except those <2 months of age. The number of patients with rotavirus gastroenteritis in all age groups declined except for children <2 months of age and those 2-5 months of age. Conclusion: These results show that after the introduction of a rotavirus vaccine in Korea, the incidence of rotavirus gastroenteritis decreased in 6-59-month-old patients hospitalized for acute gastroenteritis.

This study aimed to analyze the association of midpalatal suture (MPS) maturation stages with skeletal maturation and age and to obtain references for establishing a treatment plan for rapid maxillary expansion (RME). Cone-Beam Computed Tomography (CBCT) images from 480 children (240 boys, 240 girls) aged 7 - 15 years were obtained. MPS maturation stages and cervical vertebral maturation indicator (CVMI) were evaluated, and the correlations between MPS maturation stages, CVMI, and age were determined using the Spearman's correlation test. The positive likelihood ratio (LHR) of CVMI for MPS maturation stages was calculated. MPS maturation stages and CVMI showed a strong correlation. Especially, CVMI 1 - 3 showed positive LHR greater than 10 for the diagnosis of stages A - C. MPS maturation stages and age were correlated strongly in girls and moderately in boys. Conventional RME produces the most favorable skeletal effect at CVMI 1 - 3 or those up to 12 years of age and fewer skeletal effects at CVMI 4 or at 13 years of age in girls and 13 - 15 years in boys. It is recommended to evaluate MPS maturation stages using CBCT before RME application at CVMI 5, 6 or at 14, 15 years of age in girls.

Purpose: Serological tests of tissue transglutaminase (TTG) and deamidated gliadin (DGP) antibodies for celiac disease diagnosis show conflicting correlation with histology in young children and in type 1 diabetes mellitus (T1DM). Tests' ability to predict histology and cutoff values based on age and T1DM was evaluated. Methods: A retrospective study of children who had celiac serological tests between 6/1/2002 and 12/31/2014 at a pediatric hospital. Results: TTG IgA displayed similar results in predicting histology between <4.0 and ≥4.0 years age groups with sensitivity 98% and 93%, and specificity 88% and 86%, respectively. In children <4.0 years old, sensitivity for DGP antibodies was 100% and specificity 94%; in ≥4.0 years age groups, sensitivity was 60%, 88% for DGP IgA and IgG and specificity 95%, 96%, respectively. TTG IgA had low specificity in patients with T1DM compared with non-T1DM, 42% vs. 91%. Positive TTG IgA with normal histology was associated with higher T1DM prevalence at 36% compared with negative tests at 4%. Finally, the TTG IgA cutoff value was higher in T1DM at 36 vs. 16.3 units in non-T1DM. DGP IgG cutoff showed similar values between age groups; TTG IgA and DGP IgA cutoffs were lower in <4.0 years at 8.3 and 11.9 units than ≥4.0 years at 23.4 and 19.9, respectively. Conclusion: TTG IgA is sufficient for the <4.0 years age group and DGP antibodies had no advantage over TTG IgA in older children. The cutoff value to determine a positive TTG IgA should be higher for children with T1DM.

Objectives : A substantial number of craniopharyngiomas recur despite gross total excision. The purpose of our study was to investigate pattern of recurrence and to verify prognostic factors for recurrence after gross total excision of craniopharyngiomas in children. Methods : A series of 36 patients with craniopharyngiomas were reviewed. All patients had undergone gross total excision and none of them received radiotherapy after initial surgery. Fifteen were girls and twenty-one were boys, with a mean age of 7.3 years(range, one to 15 years). The mean follow-up period was 52 months(range, one to 149 months). Recurrence was noted in 14 patients within 83 months(mean 31.4 months). Results : The overall three-year recurrence free survival rate was 65%, and the five-year recurrence-free survival rate was 55%. Regular neuroimaging follow-up at six to 12-month intervals detected tumor recurrence of a smaller size before symptoms developed(p<0.05). At the first surgical procedure, the optic nerve/chiasm(n=23) was the most common adhesion site. The most frequent sites of recurrence were the optic nerve/chiasm(n=6) and the pitiutary fossa(n=6). Tumor location was the single significant clinical predictor of recurrence. The five-year recurrence-free survival rate was 39% for those who had an intrasellar tumor component and 81% for those who did not (p<0.05). Conclusion : Craniopharyngiomas with intrasellar components should be followed cautiously and regular followup of patients should be emphasized, even when the tumors are totally resected.

Purpose: The purpose of this study was to investigate the importance of initial screening tests for depression and anxiety disorders in children with headache. In addition, this study evaluated whether the Children's Depression Inventory (CDI) and Revised Children's Manifest Anxiety Scale (RCMAS) are suitable for screening symptoms of depression and anxiety. Methods: A retrospective chart review was conducted of 720 children aged 7-17 years who had visited a pediatric neurology clinic for headaches and were referred to a pediatric psychiatric clinic for psychiatric symptoms from January 2010 to December 2011. All patients completed the CDI and RCMAS. Among them, charts of patients with clinically significant total scores (cutoff>15) for psychiatric symptoms, as defined by the CDI and RCMAS scoring scales, were reviewed. Results: Nineteen patients had headaches and clinically significant total scores for psychiatric symptoms. The mean age at headache diagnosis was 11.7 years, and 57% were male. Mean duration of headache was 11.5 months. Two point eight percent of the patients were diagnosed with psychiatric disorders including major depression (1.7%), generalized anxiety disorder (1.1%), and bipolar disorder (0.1%). Four patients (0.6%) were diagnosed with attention deficit/hyperactivity disorder (ADHD). Total mean CDI and RCMAS scores of patients referred to the psychiatric clinic were 18.8 and 22.2, respectively. There was no correlation between CDI or RCMAS total scores and headache frequency, duration, or severity. Conclusion: We recommend that all patients with headache should be screened for depression and anxiety by CDI and RCMAS scores.

Purpose: Familial Mediterranean fever (FMF) is an auto inflammatory disease characterized by periodic fever, synovitis and serositis. Patients may be admitted to gastroenterology units due to gastrointestinal symptoms. In this study; we aimed to analyze endoscopic findings and diagnostic utility of endoscopic procedure in children with FMF. Methods: Patient with FMF that was performed endoscopy for the gastrointestinal symptoms were included to the study (39 of 164 patients, 53 procedure). A control group was randomly designed as age and gender matched four endoscopic procedures per one endoscopic procedure of patients with FMF (n=212). Results: No different was found between the patients and control group in esophagogastroscopy findings. However, the diagnosis of gastrointestinal pathology was made by esophagogastroscopy in 46.2% patients. Colonoscopic examination revealed that the frequency of inflammatory bowel disease (IBD) was higher in undiagnosed patients compared to both the control group (50.0% vs. 6.9%, p<0.05, odds ratio [OR]:13.4 and 95% confidence inteval [95% CI]: 2.1-84.3) and the patients under colchicine treatment (50.0% vs. 8.3%, p<0.05, OR: 11 and 95% CI: 0.8-147.8). Colonoscopic procedure that was made after the diagnosis was found to provide contribution by 16.7% in determining the etiology of the additional symptoms. Conclusion: Patients with FMF may be admitted to pediatric gastroenterology outpatient clinic prior to diagnosis or during the follow-up period. The frequency of IBD is high in undiagnosed patients with FMF. Endoscopic procedures may be helpful in these patients for the diagnosis accompanying mucosal lesions.

Purpose: Autoimmune hepatitis (AIH) is a chronic disease that may lead to cirrhosis. The immunopathogenesis of AIH is not fully understood and it mainly involves T-cell mediated mechanism. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that promotes T cell response and its polymorphism may serve as a severity marker of AIH. No previous study has considered investigating MIF polymorphism in children with AIH. Methods: Forty-two children with definite diagnosis of AIH were enrolled along with 100 age and sex matched controls. All participants were tested for polymorphism at -173GC (rs755622) of MIF gene. All patients received the standard protocol of steroid plus azathioprine to achieve remission. Liver biopsy was performed at time of diagnosis for all patients and only 18 of them underwent a second biopsy after treatment. Results: No statistically significant differences in the frequency of the genotypes GG and GC or in allele distribution were found in both patient and control groups (p=0.590, 0.640 respectively). Initial alanine aminotransferase (ALT) levels at the time of presentation was significantly higher in the GC group than GG group (p=0.020). GC genotype significantly correlated with disease relapse (r=0.41, p=0.007). Regression of necroinflammation and the fibrosis score in the second liver biopsy was statistically significant in the GG group (p<0.0001, p=0.010 respectively). Conclusion: MIF -173GC polymorphism is associated with clinically significant markers of pediatric AIH, including increased initial serum ALT levels, may help predict necroinflammatory/fibrosis regression effectively, following immunosuppressive treatment.
