Abstract
Purpose Effectiveness and safety of clofarabine (one of the treatment mainstays in pediatric patients with relapsed/refractory acute lymphoblastic leukemia [ALL]) was assessed in Korean pediatric patients with ALL to facilitate conditional coverage with evidence development. Materials and Methods In this multicenter, prospective, observational study, patients receiving clofarabine as mono/combination therapy were followed up every 4–6 weeks for 6 months or until hematopoietic stem cell transplantation (HSCT). Response rates, survival outcomes, and adverse events were assessed. Results Sixty patients (2–26 years old; 65% B-cell ALL, received prior ≥ 2 regimen, 68.3% refractory to previous regimen) were enrolled and treated with at least one dose of clofarabine; of whom 26 (43.3%) completed 6 months of follow-up after the last dose of clofarabine. Fifty-eight patients (96.7%) received clofarabine combination therapy. Overall remission rate (complete remission [CR] or CR without platelet recovery [CRp]) was 45.0% (27/60; 95% confidence interval [CI], 32.4 to 57.6) and the overall response rate (CR, CRp, or partial remission [PR]) was 46.7% (28/60; 95% CI, 34.0 to 59.3), with 11 (18.3%), 16 (26.7%), and one (1.7%) patients achieving CR, CRp, and PR, respectively. The median time to remission was 5.1 weeks (95% CI, 4.7 to 6.1). Median duration of remission was 16.6 weeks (range, 2.0 to 167.6 weeks). Sixteen patients (26.7%) proceeded to HSCT. There were 24 deaths; 14 due to treatment-emergent adverse events. Conclusion Remission with clofarabine was observed in approximately half of the study patients who had overall expected safety profile; however, there was no favorable long-term survival outcome in this study.

Abstract
BACKGROUND Hodgkin's lymphoma (HL) constitutes 10%-20% of all malignant lymphomas and has a high cure rate (5-year survival, around 90%). Recently, interest has increased concerning preventing secondary complications (secondary cancer, endocrine disorders) in long-term survivors. We aimed to study the epidemiologic features and therapeutic outcomes of HL in children, adolescents, and young adults in Korea. METHODS We performed a multicenter, retrospective study of 224 patients aged < 25 years diagnosed with HL at 22 participating institutes in Korea from January 2007 to August 2016. RESULTS A higher percentage of males was diagnosed at a younger age. Nodular sclerosis histopathological HL subtype was most common, followed by mixed cellularity subtype. Eighty-one (36.2%), 101 (45.1%), and 42 (18.8%) patients were classified into low, intermediate, and high-risk groups, respectively. Doxorubicin, bleomycin, vinblastine, dacarbazine was the most common protocol (n = 102, 45.5%). Event-free survival rate was 86.0% ± 2.4%, while five-year overall survival (OS) rate was 96.1% ± 1.4%: 98.7% ± 1.3%, 97.7% ± 1.6%, and 86.5% ± 5.6% in the low, intermediate, and high-risk groups, respectively (P = 0.021). Five-year OS was worse in patients with B-symptoms, stage IV disease, high-risk, splenic involvement, extra-nodal lymphoma, and elevated lactate dehydrogenase level. In multivariate analysis, B-symptoms and extra-nodal involvement were prognostic factors for poor OS. Late complications of endocrine disorders and secondary malignancy were observed in 17 and 6 patients, respectively. CONCLUSION This is the first study on the epidemiology and treatment outcomes of HL in children, adolescents, and young adults in Korea. Future prospective studies are indicated to develop therapies that minimize treatment toxicity while maximizing cure rates in children, adolescents, and young adults with HL.

Abstract
BACKGROUND Vitrification is the most popular technique for the cryopreservation of oocytes and embryos, replacing slow freezing methods. MATERIALS AND METHODS This study evaluated the efficient manufacturing methods of handmade open pulled straw (OPS) with a digital heating gun that could be proposed for vitrification. RESULTS Production efficiency of OPS using 0.5 mL straw was detected at 0, 66.1, 90.5 and 85.7% for 1~2 s and 9.5, 33.3, 47.6 and 23.8% for 2~3 s of heating time at 250, 350, 400 and 450°C respectively. The production rate of OPS using 0.25 mL straw was perceived at 33.3, 76.2, 83.3, 95.2 and 57.6 % for 1.5~2.5 s time with the optimized heat setting at 330, 340, 350, 360 and 370°C respectively. The desired inner diameter (200~300 μm) of OPS could be varied according to the gamete size, embryo developmental stages or cell lines of different species. Based on our data, the production efficiency of OPS using 0.25-mL straw were increased beyond using a 0.5-mL straw. CONCLUSION Handmade OPSs could be efficiently produced with a digital heating gun to generate a vitrification device for freezing gametes, embryos and cell lines.

Abstract
BACKGROUND We aimed to compare the therapeutic efficacy of prolonged macrolide (PMC), corticosteroids (CST), doxycycline (DXC), and levofloxacin (LFX) against macrolide-unresponsive Mycoplasma pneumoniae (MP) pneumonia in children and to evaluate the safety of the secondary treatment agents. METHODS We retrospectively analyzed the data of patients with MP pneumonia hospitalized between January 2015 and April 2017. Macrolide-unresponsiveness was clinically defined with a persistent fever of ≥ 38.0°C at ≥ 72 hours after macrolide treatment. The cases were divided into four groups: PMC, CST, DXC, and LFX. We compared the time to defervescence (TTD) after secondary treatment and the TTD after initial macrolide treatment in each group with adjustment using propensity score-matching analysis. RESULTS Among 1,165 cases of MP pneumonia, 190 (16.3%) were unresponsive to macrolides. The proportion of patients who achieved defervescence within 48 hours in CST, DXC, and LFX groups were 96.9% (31/33), 85.7% (12/14), and 83.3% (5/6), respectively. The TTD after initial macrolide treatment did not differ between PMC and CST groups (5.1 vs. 4.2 days, P = 0.085), PMC and DXC groups (4.9 vs. 5.7 days, P = 0.453), and PMC and LFX groups (4.4 vs. 5.0 days, P = 0.283). No side effects were observed in the CST, DXC, and LFX groups. CONCLUSION The change to secondary treatment did not show better efficacy compared to PMC in children with macrolide-unresponsive MP pneumonia. Further studies are needed to guide appropriate treatment in children with MP pneumonia.

Abstract
PURPOSE Crohn's disease (CD) can involve any site of the gastrointestinal tract (GIT). However, the characteristics of upper GIT involvement in CD are unclear, especially in the Eastern pediatric population. This study aimed to estimate the prevalence of upper GIT involvement and identify the clinical features of Korean children with CD. METHODS This was a retrospective multicenter cohort study that included 52 pediatric patients with CD who underwent esophagogastroduodenoscopy and biopsy. The clinical symptoms and endoscopic and histologic features of the upper GIT were identified according to the presence or absence of upper gastrointestinal symptoms. RESULTS Among the 52 patients, upper GIT involvement was noted in 50.0% (26/52). The mean age at CD diagnosis was 14.1±2.1 years. Gastric ulcer was the most common lesion (19.2%) found on upper GIT endoscopy, followed by duodenal ulcers (15.4%). Chronic inflammation was the most common histopathologic feature (75.0%), followed by gastric erosion (17.3%). Granuloma was found in 9.6% of patients. Helicobacter pylori infection was identified in 5.8% of patients. Endoscopic and histologic findings were not significantly different, but the mean values of erythrocyte sedimentation rate (60.7±27.1 vs. 43.0±27.6 mm/h, p=0.037) and C-reactive protein (16.5±28.2 vs. 6.62±13.4 mg/dL, p=0.014) were significantly different between patients with and without upper gastrointestinal CD symptoms. CONCLUSION Upper GIT involvement was relatively common in pediatric patients with CD irrespective of upper gastrointestinal symptoms, and H. pylori infection was relatively uncommon. The results of this study should aid the establishment of regional guidelines for upper GIT examination.

Abstract
Purpose Mycoplasma pneumoniae (MP) infection is a major cause of respiratory infection in school-aged children. Extrapulmonary manifestations of MP infection are common, but liver involvement has been rarely reported. The aim of this study was to determine the clinical characteristics of MP-associated hepatitis. Methods This prospective study included 1,044 pediatric patients with MP infection diagnosed serologically with MP IgM at one medical center from January 2006 to December 2012. Eighty of these patients had elevated levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT), each greater than 50 IU/L, without any other specific liver disorder and were compared with the 964 children without liver disorders. Results In total, 7.7% of patients with MP infection had a diagnosis of hepatitis, especially in fall and winter. The ratio of male to female patients was 1.7:1, and the mean age of the patients was 5 years and 5 months. The most common symptoms were cough, fever, and sputum. Anorexia was the most common gastrointestinal symptom, followed by nausea/vomiting, diarrhea, and abdominal pain. Mean levels of AST and ALT were 100.65 IU/L and 118.73 IU/L, respectively. Serum AST/ALT level was normalized within 7.5 days on average without complications. The mean duration of hospitalization (11.3 days) was longer for children with hepatitis than for those without hepatitis (P=0.034). Conclusion MP-associated hepatitis is not uncommon and has a relatively good prognosis. Therefore, clinicians should be concerned about liver involvement in MP infection but avoid further unnecessary evaluation of hepatitis associated with MP.

Abstract
Severe congenital neutropenia (SCN) is a heterogeneous group of disorders with a defect in granulopoiesis causing marked neutropenia and severe bacterial infections. A 17-month-old girl (patient 1) was admitted due to cervical lymphadenitis caused by methicillin-resistant Staphylococcus aureus, with neutropenia. She had Pseudomonas aeruginosa sepsis and peritonitis with perforated appendicitis at 8-month of age. Her sister, a 37-month-old girl (patient 2), had recurrent stomatitis with profound neutropenia, and her mother, a 32-yr-old woman (patient 3), had had recurrent stomatitis until her early 20s with neutropenia. We found an ELANE gene mutation (c.597+1G > A) from them in direct DNA sequencing analysis. Patients 1 and 2 did not respond to granulocyte colony stimulating factor and patient 1 was treated with prolonged antibiotics and excision. We demonstrated inherited SCN cases showing different severity even with the same mutation of the ELANE gene in a family.

Abstract
PURPOSE Meckel's diverticulum (MD) has various clinical manifestations, and diagnosis or selectection of proper diagnostic tools is not easy. This study was conducted in order to assess the clinical differences of MD diagnosed by scintigraphic and non-scintigraphic methods and to find the proper diagnostic tools. METHODS We conducted a retrospective review ofthe clinical, surgical, radiologic, and pathologic findings of 34 children with symptomatic MD, who were admitted to Gachon University Gil Medical Center, Inha University Hospital, and The Catholic University of Korea, Incheon St. Mary's Hospital between January 2000 and December 2012. The patients were evaluated according to scintigraphic (12 cases; group 1) and non-scintigraphic (22 cases; group 2) diagnosis. RESULTS The male to female ratio was 7.5: 1. The most frequent chief complaint was lower gastrointestinal (GI) bleeding in group 1 and nonspecific abdominal pain in group 2, respectively. The most frequent pre-operative diagnosis was MD in both groups. Red blood cell (RBC) index was significantly lower in group 1. MD was located at 7 cm to 85cm from the ileocecal valve. Four patients in group 1 had ectopic gastric tissues causing lower GI bleeding. The most frequent treatment modality was diverticulectomy in group 1 and ileal resection in group 2, respectively. CONCLUSION To diagnose MD might be delayed unless proper diagnostic tools are considered. It is important to understand indications of scintigraphic and non-scintigraphic methods according to clinical and hematologic features of MD. Scintigraphy would be weighed in patients with anemia as well as GI symptoms.

Abstract
FLT3 mutations are common genetic changes, and are reported to have prognostic significance in acute myeloid leukemia (AML). The FLT3 internal tandem duplication (ITD) and the D835 activating mutation in the tyrosine kinase domain (TKD) were analyzed by polymerase chain reaction (PCR) in the genomic DNA of Korean patients with AML at diagnosis and during follow-up. There were 226 patients with AML enrolled between March 1996 and August 2005. The incidence of ITD and TKD at diagnosis was 13% (29/226) and 3% (6/226). When compared to Western and other Asian patients with AML, Korean patients had a lower frequency by about two-thirds of ITD and TKD. Among the non-M3 cases (N=203), the patients with an ITD had a significantly shorter event-free survival when compared with those without an ITD (p=0.0079). Among 54 relapsed patients, 9 patients had the FLT3 ITD at diagnosis. Six patients demonstrated a reappearance of the ITD and 3 patients remained negative at relapse. One patient, among 45 patients who relapsed, had a negative baseline ITD but acquired a de novo ITD at relapse. There were 101 samples from 93 patients in remission; they were all negative for an ITD. Among 34 patients who failed to achieve a remission, five patients had a persistent ITD and one patient had a de novo ITD. These results support the concept of resistance of FLT3 ITD leukemic clones to chemotherapy. Therefore, effective therapy with FLT3 targeting agents may improve the prognosis of non-M3 AML patients with the FLT3 mutation.

Abstract
OBJECTIVE Survival of periodontal ligament cells is crucial issue after tooth replantation. To understand this matter, we introduced MTT assay, which can be used as a tool for measuring the viability of periodontal ligament cells from extracted rat molars. MATERIALS AND METHODS The maxillary molars of 4-week-old Sprague-Dawley white female rats were used. Ten teeth of each immediate, 1 h Viaspan and 1 h dry were processed for MTT evaluation. Another 10 teeth from each group were treated in the same manner as above, but were replanted into their original socket. After 2 weeks, the animals were killed and the prevalence of resorption pits was evaluated. RESULTS In vivo MTT assay corresponded with the histological results of the resorption pits (P <or= 0.05). The polarizing and optical microscopic findings were consistent with the in vivo MTT assay results. CONCLUSIONS In vivo MTT measurements were consistent with the histologic observations and suggest that the in vivo MTT assay could be a tool for evaluating the viability of periodontal ligament cells directly from the extracted root surface. The advantages are shorter analysis time compared with animal or cell culture experiments, easy manipulation, clear quantification and immediate identification of the vital cells.

Abstract
ETV1, ERM and E1A-F are members of the multigene ETS domain containing a class of transcription factors, first identified in the genome of the avian retrovirus E26. Based upon extensive homology between these genes within their ETS domain (96% identity each other), these three genes comprise a distinct sub-family of ETS genes as a human PEA3 sub-family. By analyzing somatic cell hybrid segregating human chromosomes, the genes encoding ETV1, ERM and E1A-F were localized to human chromosome 7, 3 and 17, respectively. Fluorescence in situ hybridization confirmed these assignments and allowed mapping of the genes to 7p22 (ETV1), 3q29 (ERM) and 17q12 (E1A-F). These results suggest the ancestral PEA3 gene may have duplicated first, then dispersed to other chromosomal locations.

Abstract
Chimeric transcription factors, created by gene fusions as the result of chromosomal translocations, have been implicated in the pathogenesis of several pathologically disparate solid tumors. The PAX3/FKHR fusion gene, formed by a t(2;13)(q35;q14) in alveolar rhabdomyosarcoma, encodes a hybrid protein that contains both PAX3 DNA binding domains, the paired box and homeodomain, linked to the bisected DNA binding domain of FKHR, a member of the forkhead family of transcription factors. Here we report that PAX3 and PAX3/FKHR display similar, but not identical transactivation activities when tested with model Pax recognition sequences. No functional role could be ascribed solely to the residual FKHR binding domain present in the fusion protein, but FKHR was found to contribute a strong carboxyl terminal activation domain replacing the one located in the unrearranged PAX3 gene. We show that the native PAX3/FKHR protein present in tumor cells with this translocation has transcriptional characteristics similar to the in vitro expressed protein. The ability of the PAX3/FKHR hybrid protein to bind DNA in a sequence specific manner and to transactivate the expression of artificial reporter genes suggests that its aberrant expression could subvert the transcriptional programs that normally control the growth, differentiation, and survival of primitive myogenic precursors in vivo.

Abstract
Most Ewing's sarcomas or related primitive neuroectodermal tumors have the (11;22)(q24;q12) or less frequently the (21;22)(q22;q12) translocation. These rearrangements fuse the EWS gene on chromosome 22q12 to either the FLI1 or ERG genes, both members of the ETS family of transcription factors. Simple variant chromosomal translocations have been occasionally described in these tumors. We have identified a third Ewing's sarcoma translocation, the t(7;22)(p22;q12), that fuses EWS to the human homologue of the murine ETS gene ER81. This gene, designated ETV1 (for ETS Translocation Variant), is located on chromosome band 7p22. Identical EWS nucleotide sequences found in the majority of EWS-FLI1 and EWS-ERG chimeric transcripts are fused to a portion of ETV1 encoding an ETS domain with sequence specific DNA-binding activity. These findings confirm that the fusion of EWS to different ETS family members can result in a similar tumor phenotype.

Abstract
Incidence of and contributory factors in postintubation laryngeal edema were determined in 7875 children under 17 years of age. Data were assembled in the manner of a prospective study. With an overall incidence of 1 percent, children between ages 1 and 4 were most susceptible. Excessive size of the endotracheal tube was suspect in half of the cases. Other factors that increase trauma to the larynx while an endotracheal tube is in place showed significant correlation to the total incidence of postintubation laryngeal edema. No tracheostomies were required.
