Abstract
This study investigated the anti-inflammatory effects of cell-free supernatant of Lactococcus lactis IDCC 2301 on lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Expression of inflammatory mediators and cytokines, and the production of nitric oxide (NO) and prostaglandin E2 (PGE2) were qualitatively analysed. The expression of signal transductors in inflammatory cascades was quantified by western blot. Treatment with cell-free supernatant of L. lactis IDCC 2301 significantly decreased the mRNA expression levels of tumour necrosis factor (TNF-α) and interleukins including IL-1β and IL-6. The levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) were also remarkably reduced in LPS-induced macrophages after the treatment. Furthermore, L. lactis IDCC 2301 reduced the levels of both dephosphorylated and phosphorylated forms of nuclear factor-kappa B (NF-κB), IκB-α, extracellular signal-regulated kinases (ERK), c-Jun amino-terminal kinases (JNK), and p38 in LPS-induced RAW 264.7 cells. Therefore, L. lactis IDCC 2301 shows anti-inflammatory activity by suppressing the NF-κB and mitogen-activated protein kinase (MAPK) signaling pathways.

Abstract
OBJECTIVES We primarily aimed to evaluate whether parotid incidental lesion (PIL) in 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for staging evaluation of patients with hepatocellular carcinoma (HCC) would represent a possibility of extrahepatic metastasis or second primary malignancy (SPM). Additionally, we explored the incidence of PIL in HCC patients and examined any associated risk factors. METHODS We retrospectively analyzed patients with HCC who underwent 18F-FDG PET/CT at our institution from 2010 to 2022. The pathological findings of PILs in HCC patients were investigated for confirmatory identification of the risk of HCC metastasis or SPM in parotid gland. Healthy controls received 18F-FDG PET/CT for health screening were also enrolled to compare the incidence of PILs with HCC patients. Various parameters associated with patient demographics and characteristics of HCC were analyzed to find the related factors of PILs. RESULTS A total of 17,674 patients with HCC and 2,090 healthy individuals who had undergone 18F-FDG PET/CT scans were enrolled in the analyses. Among the 54 HCC patients who underwent pathological confirmation for PILs, benign primary parotid tumor was most commonly observed (n = 43 [79.6%]); however, no malignant lesions were detected, including HCC metastasis. The incidence of PILs was higher in patients diagnosed with HCC compared with the control group (485 [2.7%] vs. 23 [1.1%], p = 0.002). Analysis for the risk factors for PILs revealed that patient age, sex, and positive viral markers were significantly associated with the incidence of PILs in patients with HCC (all p < 0.001). CONCLUSIONS Our study demonstrates that PILs are more frequently identified in patients with HCC on 18F-FDG PET/CT. However, no malignant PIL, including extrahepatic metastasis of HCC, was identified. Therefore, the presence of PIL should not impede or delay the treatment process for patients with HCC. Additionally, we suggested that for future swift and straightforward differential diagnoses of PIL, the development of additional protocols within the PET/CT imaging could be beneficial.

Abstract
PURPOSE This study aimed to determine the presence of peripheral spondyloarthritis and investigate the clinical characteristics of patients with concurrent peripheral spondyloarthritis in those presenting with refractory plantar fasciitis and Achilles tendinopathy by conducting human leukocyte antigen B-27 (HLA-B27) testing. METHODS This retrospective study aimed to investigate patients who complained of persistent pain and significant limitations in daily activities due to their respective foot pain, despite receiving conservative treatment for over one year under the diagnosis of plantar fasciitis or insertional Achilles tendinopathy. The study included 63 patients who underwent HLA-B27 testing. The patients were classified into two groups based on the presence or absence of HLA-B27 positivity. The Mann-Whitney U test assessed significant relationships between continuous variables, and the chi-square test was used to compare categorical variables. RESULTS Among the 63 included patients, HLA-B27 positivity was confirmed in 11 patients (17.5%), which was significantly associated with a lower average age (22.8 years versus 31.7 years, P = 0.01) and a substantially lower proportion of females compared to HLA-B27-negative patients (9.1% vs. 25.0%, P = 0.001). Ten of the 11 patients initiated treatment with conventional synthetic disease-modifying antirheumatic drugs (DMARDs) combined with oral steroids as the first-line medication after being diagnosed as HLA-B27 positive. Six patients experienced pain relief with the first-line medication (60%). Four patients who did not achieve pain control with the first-line medication received tumour necrosis factor-alpha inhibitors as the second-line medication. Two patients experienced pain relief, while two experienced reduced but persistent pain. CONCLUSIONS Among the patients with "refractory" plantar fasciitis and insertional Achilles tendinopathy, 17.5% were diagnosed with peripheral spondyloarthritis. Patients diagnosed with peripheral spondyloarthritis had a higher proportion of men and relatively younger mean age compared to those without the diagnosis. Approximately 70% of these patients achieved symptom improvement in foot and ankle joints by taking conventional synthetic DMARDs, TNF-α inhibitors, or both appropriate for spondyloarthritis.

Abstract
BACKGROUND Cervical lymph node metastasis (CLNM) from remote primary sites is rare in head and neck cancer. The efficacy of neck dissection is still being investigated for therapeutic benefits of local management in oligometastasis from non-head and neck cancer. OBJECTIVES To evaluate the clinical efficacy of neck dissection (ND) in CLNM from distant primary cancers and identify factors contributing to improved survival. MATERIALS AND METHODS This retrospective case-control study enrolled patients who underwent ND for CLNM from distant primary cancer at Asan Medical Centre between January 2010 and December 2020. We analysed overall survival and association between clinical covariate and survival. RESULTS The study included 31 (14 males, 17 females) among 114 patients. Ovarian cancer was the most common primary malignancy (32.3%). Patients with fewer than three metastatic lymph nodes, without extranodal extension and with adjuvant therapy after surgery had better survival rates. CONCLUSION AND SIGNIFICANCE In patients with CLNM from a distant primary cancer, ND is beneficial as local treatment. And adequate selection of patients for ND is pivotal to improve prognosis.

Abstract
The genus Allium comprises some of the most commonly consumed food crops worldwide. The chloroplast genomes of A. sacculiferum, A. thunbergii, and A. taquetii are 152,444, 153,459, and 154,056 bp circular molecular genomes, respectively. The annotation results revealed the presence of 132 (89 protein-coding, 35 tRNA, and eight rRNA), 132 (86 protein-coding, 38 tRNA, and eight rRNA), and 132 (86 protein-coding, 38 tRNA, and eight rRNA) genes with 36.78%, 36.83%, and 36.88% total GC content in each genome, respectively. The chloroplast genome of each Allium species contains an 81,254, 82,473, and 83,068 bp LSC region, an 18,176, 18,006, and 17,958 bp SSC region, and a pair of 26,507, 26,490, and 26,515 bp IR regions, respectively. Phylogenetic analysis based on the 21 complete chloroplast genomes indicates that A. sacculiferum is closely related to A. koreanum; A. thunbergii and A taquetii are closely related to A. hookeri. This study shows that the three Allium species are Korean crop wild relatives that may be used to develop new Allium varieties in the future.

Abstract
BACKGROUND maxillary bone invasion (MBI) is not uncommon in hard palate or upper alveolus (HP/UA) cancer; however, there have been relatively few reports about the MBI of HP/UA cancer. PATIENTS AND METHODS this was a multi-center retrospective study, enrolling 144 cases of HP/UA cancer. MBI was defined by surgical pathology or radiology follow-up. The multiple prediction models for MBI were developed in total cases and in cases having primary bone resection, using clinical and radiological variables. RESULTS computerized tomography (CT) alone predicted MBI, with an area under receiver operating curve (AUC) of 0.779 (95% confidence interval (CI) = 0.712-0.847). The AUC was increased in a model that combined tumor dimensions and clinical factors (male sex and nodal metastasis) (0.854 (95%CI = 0.790-0.918)). In patients who underwent 18fluorodeoxyglucose positron emission tomography/CT (PET/CT), the discrimination performance of a model including the maximal standardized uptake value (SUVmax) had an AUC of 0.911 (95%CI = 0.847-0.975). The scoring system using CT finding, tumor dimension, and clinical factors, with/without PET/CT SUVmax clearly distinguished low-, intermediate-, and high-risk groups for MBI. CONCLUSION using information from CT, tumor dimension, clinical factors, and the SUVmax value, the MBI of HP/UA cancer can be predicted with a relatively high discrimination performance.

Abstract
BACKGROUND To date, the optimal operative treatment for mucous cysts of the lesser toes (MCLT) has not been discussed in detail, although many previous studies have focused on treating finger lesions. Therefore, we evaluated the operative outcomes of two different procedures for MCLT: cyst excision with osteophytectomy and cyst excision with distal interphalangeal (DIP) fusion. METHODS We retrospectively reviewed and compared the clinico-radiographic outcomes of patients who underwent cyst excision with osteophytectomy (group 1, 22 cases) or cyst excision with DIP fusion (group 2, 16 cases) for MCLT between January 2010 and August 2021. The minimum follow-up duration for inclusion in the study was 12 months. Clinical outcomes were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) lesser toes metatarsophalangeal-interphalangeal scale and the Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) subscale. We also collected information on postoperative recurrence and operation-related complications. RESULTS The preoperative and postoperative AOFAS and FAAM-ADL scores were not significantly different between the two groups (P > 0.05, each). However, the postoperative recurrence rate was 31.8 % in group 1 (7 of 22 cases), whereas no recurrence was observed in group 2. Every recurrence occurred within 8 postoperative weeks (mean, 4.8 weeks; range, 3-8 weeks). Nonunion of the fusion site was observed in one patient (6.3 %). CONCLUSION We confirmed that postoperative recurrence was significantly lower in the case of cyst excision with DIP fusion than in cyst excision with osteophytectomy for the treatment of MCLT. Clinical outcomes were not significantly different between the two procedures. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
OBJECTIVE Polydeoxyribonucleotide (PDRN) is known to enhance wound healing, but there has been no clinical trial investigating the effect of PDRN on scar prevention in surgical wounds. This study aimed to evaluate the efficacy of PDRN administration in preventing postoperative scars. APPROACH In this randomized controlled trial (NCT05149118), 44 patients who underwent open thyroidectomy were randomly assigned to the PDRN treatment or untreated control group. Only patients in the treatment group received two consecutive injections of PDRN one and two days after surgery. The modified Vancouver Scar Scale (mVSS), patients' subjective symptoms, erythema index (EI), melanin index (MI), and scar height were assessed three months after surgery. RESULTS Patients in the treatment group had lower mVSS scores (1.619 ± 1.244 vs. 2.500 ± 1.540, respectively; P = 0.059) and a significantly lower vascularity subscore (0.476 ± 0.512 vs. 0.900 ± 0.447, respectively; P = 0.010) than those in the control group at the 3-month follow-up. Compared with the control group, the level of subjective symptoms, EI, and scar height were all significantly lowered in the PDRN injection group. No specific side effects related to PDRN injection were observed. INNOVATION This is the first clinical study which demonstrated that PDRN injections rapidly decreased postsurgical wound erythema and as a result, significantly reduced both excessive scar formation and accompanying symptoms. CONCLUSION Early postoperative injection of PDRN is an effective and safe treatment to prevent hypertrophic scars and improve scar outcomes.

Abstract
ObjectiveHypopharyngeal cancer is managed by either surgical resection or radiation therapy-based treatment. In choosing the treatment modality, the patient’s swallowing function should be considered to achieve optimal treatment outcomes. This study aimed to stratify the risk factors predictive of postoperative dysphagia in hypopharyngeal cancer.Study DesignRetrospective study.SettingTertiary referral center.MethodsWe enrolled 100 patients who were diagnosed with hypopharyngeal cancer and underwent curative surgery between January 2010 and December 2019, and retrospectively reviewed their medical records.ResultsPostoperative dysphagia occurred in 29 patients (29%) who required a tracheostomy tube or percutaneous gastrostomy tube for feeding or preventing aspiration; additionally, the overall survival rate was lower in those patients than in those without dysphagia. The univariate analysis revealed that postoperative dysphagia was associated with clinical T stage (p = 0.016), N stage (p = 0.002), and surgical resection extent of the larynx and pharynx (p < 0.001). Patients who underwent total laryngectomy with total/partial pharyngectomy were more likely to have dysphagia than those in the larynx-preserving pharyngectomy groups (odds ratio [OR] = 3.208, 95% confidence interval [CI] 1.283–8.024, p = 0.011). Concerning the posterior pharyngeal wall (PPW), which has an important role in swallowing, patients who underwent resection of ≥1/2 of the PPW were more likely to have dysphagia (OR = 7.467, 95% CI 1.799–30.994, p = 0.003).ConclusionsSurgical resection extent was proportionally associated with dysphagia in hypopharyngeal cancer patients. Patients with smaller lesions but no laryngeal invasion had better postoperative swallowing function than patients with larger lesions or laryngeal involved lesions. Preserving the larynx and hypopharyngeal mucosa (especially the PPW) as much as possible can help preserve postoperative swallowing function.

Abstract
Objective Postoperative delirium is known to have various adverse effects on head and neck surgery patients. This study was designed to identify possible risk factors of delirium following long periods of head and neck cancer surgery and to help prevent postoperative delirium. Methods We enrolled 197 patients who underwent long-time (>6 h) head and neck surgery at the Asan Medical Center from January 2017 to December 2018 in this study. Clinical covariates that may be associated with delirium were analyzed retrospectively using univariate and multivariate analyses. Results Delirium occurred in 18 patients (9.1%). Within the first 7 days, 16 patients (88.9%) experienced delirium. Upon univariate analysis, delirium was associated with old age (≥75, p = 0.001), past neurological history (p = 0.019), time to ambulation (p = 0.014), and postoperative hospital day (p = 0.048). In multivariate analysis, old age (≥75, odds ratios (OR) 6.16, CI 2.00–19.00, p = 0.002), time to ambulation (OR 1.04, CI 1.01–1.07, p = 0.017), and past neurological history (OR 5.26, CI 1.09–25.37, p = 0.039) were significant risk factors associated with postoperative delirium. Conclusions Older patients or patients with neurologic history must be attended with care, especially early after surgery. Encouraging early ambulation might lower the incidence of postoperative delirium and, subsequently, reduce adverse effects. This result could benefit patients by helping them avoid undesirable outcomes.

Abstract
INTRODUCTION Pulmonary metastatic head and neck cancer has a poor prognosis. Pulmonary metastasectomy has been performed but only in carefully selected patients. The aim of this study was to examine the clinical characteristics and oncological follow-up of patients who underwent pulmonary metastasectomy. METHODS Data of 54 patients with squamous-cell carcinoma (SCC) or adenoid cystic carcinoma (ACC) who underwent metastasectomy between 2003 and 2019 at two tertiary referral centers were retrospectively reviewed. RESULTS The 3-year and 5-year disease-free survival rates after metastasectomy were 49.9% and 39.9% for SCC and 38.9% and 32.4% for ACC, respectively. Univariate analysis revealed that a disease-free interval (DFI) less than 14 months and R1 resection (hazard ratio [HR] [95% confidence interval]: 2.95 [0.77-5.62], 4.64 [0.99-21.65], respectively) were risk factors for recurrence in SCC and that a high T stage (HR: 5.24 [1.22-22.58]) was a risk factor in ACC. In SCC, a DFI less than 14 months and R1 resection (hazard ratio: 6.35 [1.36-29.54], 12.79 [1.53-106.95], respectively) were risk factors in a multivariate analysis. CONCLUSION Pulmonary metastasectomy had a fair effect on head and neck SCC and ACC, and the prognosis was better in SCC patients with a DFI greater than 14 months.

Abstract
BACKGROUND To determine the efficacy of preoperative Comprehensive Geriatric Assessment (CGA) in predicting postoperative complications in elderly patients undergoing head and neck cancer surgery. METHODS Medical records of patients aged ≥70 who underwent elective head and neck cancer surgery were reviewed. CGA scores were prospectively collected prior to surgery and analyzed to determine their association with postoperative complications. RESULTS Of the 65 patients enrolled in this study, 34 (52.3%) with deficits in two or more preoperative CGA domains were categorized as "frail." Fourteen patients (21.5%) experienced postoperative complications. Age was not a risk factor for the complications (p = 0.504). The multivariate analysis indicated that major postoperative complications were significantly associated with frailty (odds ratio [OR] = 21.9, p = 0.039), operation time (OR = 39, p = 0.048), and estimated blood loss (OR = 19.8, p = 0.043). CONCLUSIONS Frailty assessed by preoperative CGA, but not chronological age, was significantly associated with major postoperative complications in elderly patients undergoing head and neck cancer surgery.

Abstract
Purpose To compare the outcomes of primary radiotherapy (RT) versus surgery in early-stage human papilloma virus-positive oropharyngeal squamous cell carcinoma (hpv+OPC), and investigate the preoperative clinical factors that can predict the requirement for postoperative adjuvant treatment. Materials and Methods This multicenter study included 166 patients with AJCC 8th edition-Stages I-II hpv+OPC. Sixty (36.1%) and 106 (63.9%) patients underwent primary (CC)RT and surgery, respectively. Seventy-eight (73.6%) patients in the surgery group received postoperative (CC)RT. Results With a median follow-up of 45.6 months for survivors, the 2-year overall survival (OS), progression-free survival (PFS), and locoregional control (LC) for radiotherapy/surgery were 97.8%/96.4%, 91.1%/92.0%, and 92.9%/93.3%, respectively. In multivariate analyses, patients with synchronous radiologic extranodal extension and conglomeration (ENEcong) of metastatic LNs showed significantly poorer OS (p=0.047), PFS (p=0.001) and LC (p=0.003). In patients undergoing primary surgery, two or more clinically positive LN metastases (OR, 5.15; p=0.004) and LN metastases with ENEcong (OR, 3.75; p=0.009) were predictors of postoperative chemoradiotherapy. No patient in the primary radiotherapy group demonstrated late severe toxicity whereas 3 (2.8%), 1 (0.9%), and 1 (0.9%) patient in the surgery group showed grade 3 dysphagia, grade 3 xerostomia, and fatal oral cavity bleeding. Conclusion We found no differences in OS, PFS, and LC between upfront radiotherapy and surgery in stage I-II hpv+OPC which warrants comparison through a prospective trial in the treatment de-escalation era. However, most early-stage hpv+OPC patients undergoing surgery received adjuvant (CC)RT. Pretreatment LN findings were prognostic and predictive for adjuvant treatment.

Abstract
Probiotics play an important role in health benefits on the host. However, they also possess potentials for infectivity or in situ toxin production; thus, requiring a comprehensive assessment of their safety. In this study, we report genomic characteristics of a newly isolated Lactobacillus casei IDCC 3451 from infant faeces. Phenotypic assays based on enzyme activities and carbohydrate fermentation profiles represented metabolic features of the strain. Safety evaluation for antimicrobial resistance, biogenic amines production and cytotoxicity to a murine mouse model suggested its safe use as a probiotic strain. Our findings on the genetic background of L. casei IDCC 3451 and its potential features provide a promising functional and safe probiotic strain for the human consumption.

Abstract
BACKGROUND AND PURPOSE Transoral robotic surgery is an emerging strategy for treating human papillomavirus-positive cancers, but the role of MR imaging in predicting the surgical outcome has not been established. We aimed to identify preoperative MR imaging characteristics that predispose the outcome of transoral robotic surgery toward an insecure (positive or close) surgical margin in human papillomavirus-positive tonsillar squamous cell carcinoma. MATERIALS AND METHODS Between December 2012 and May 2019, sixty-nine patients underwent transoral robotic surgery at our institution. Among these, 29 who were diagnosed with human papillomavirus-positive tonsillar squamous cell carcinoma, did not receive neoadjuvant treatment, underwent preoperative 3T MR imaging, and had postoperative pathologic reports and were included in this retrospective study. Two neuroradiologists evaluated the preoperative MR imaging scans to determine the tumor spread through the pharyngeal constrictor muscle using a 5-point scale: 1, normal constrictor; 2, bulging constrictor; 3, thinning constrictor; 4, obscured constrictor; and 5, tumor protrusion into the parapharyngeal fat. The risk of an insecure surgical margin (involved or <1 mm) according to the MR imaging scores was predicted using logistic regression with the Firth correction. RESULTS The interobserver agreement for the MR imaging scores was excellent (κ = 0.955, P < .001). A score of ≥4 could predict an insecure margin with 87.5% sensitivity and 92.3% specificity (area under the curve = 0.899) and was the only significant factor associated with an insecure margin in the multivariable analysis (OR, 6.59; 95% CI, 3.11-22.28; P < .001). CONCLUSIONS The pre-transoral robotic surgery MR imaging scoring system for the pharyngeal constrictor muscle is a promising predictor of the surgical margin in human papillomavirus-positive tonsillar squamous cell carcinoma.

Abstract
PURPOSE Unexpected parotid cancers are often encountered due to inaccuracies in the preoperative evaluation. This study aimed to examine the clinical characteristics and oncological outcomes of these cancers and to propose the appropriate management strategy. METHODS This is a multicenter case series study in which a total of 302 patients were diagnosed postoperatively with parotid cancers between 2003 and 2017. Of these, 85 cases without evidence of malignancy prior to surgery but identified as malignant on postoperative pathology were included. RESULTS Of 85 patients, 76 and 9 underwent superficial and total parotidectomy, respectively. A positive resection margin was present in 24.7% of the cases. Postoperative radiotherapy was administered to 43.6% of patients; 4.2% had a local recurrence, and no patients died of the disease. The 5-year overall and relapse-free survival rates were 100.0% and 95.2%, respectively. Patients who underwent piecemeal resection had significantly poorer oncologic outcomes. Age, sex, histologic grade, T stage, extracapsular extension, resection margin status, and postoperative radiotherapy did not affect recurrence and survival. CONCLUSION Preoperatively unexpected parotid cancers had excellent local control and overall survival despite positive or close resection margin, with or without postoperative radiotherapy. Therefore, patients with unexpected parotid malignancies may benefit from less aggressive postoperative management option.

Abstract
Background Although oropharyngeal squamous cell carcinoma (OPSCC) with human papillomavirus (HPV) infection has a good prognosis, the accurate prediction of survival and risk of treatment failure is essential to design deintensification regimens. Here, we investigated estrogen receptor α (ERα) as a prognostic biomarker with therapeutic implications in OPSCC alongside factors associated with HPV infection. Methods We performed immunohistochemistry for ERα and p53 using formalin-fixed, paraffin-embedded tissues and assessed the HPV status using p16 immunohistochemistry and HPV DNA testing in 113 consecutive patients with OPSCC treated with surgical resection or radiotherapy/chemoradiotherapy. Results ERα expression and p53 alteration was observed in 35.4% and 21.2% OPSCCs; 45.6% and 1.3% p16+/HPV+ OPSCCs; and 11.5% and 76.9% p16− OPSCCs, respectively. These data suggest that OPSCC pathogenesis varies with HPV status. Furthermore, ERα expression was associated with improved overall survival (OS) in both HPV+ (p16+/HPV+ OPSCC) and p16+ (p16+ OPSCC irrespective of HPV status) models (p = 0.005 and p = 0.006, respectively) and with improved OS adjusted for stage (p = 0.037, hazard ratio: 0.109, 95% confidence interval 0.013–0.871) in the p16+ model. Conclusions ERα is a potential predictive biomarker for improved survival in both HPV+ and p16+ OPSCC models.

Abstract
OBJECTIVES The aim of this study was to analyze the risk of malignancy in salivary gland tumors on the basis of the Milan System for Reporting Salivary Gland Cytopathology. METHODS A retrospective review was performed of the charts of patients with salivary gland tumors in whom the final diagnosis was confirmed by surgical excision. Preoperative fine needle aspiration results were categorized according to the Milan System for Reporting Salivary Gland Cytopathology: non-diagnostic (category I), nonneoplastic (category II), atypia of undetermined significance (category III), neoplasm (category IV), suspicious for malignancy (category V), and malignant (category VI). Fine needle aspiration and final diagnosis were compared, and the risk of malignancy and operative/oncological outcomes were analyzed. RESULTS A total of 288 patients were enrolled in this study. Postoperative histopathologic salivary gland malignancies were found in 30 (10.4%) patients. Risk of malignancy was 7.1%, 0%, 48.0%, 4.8%, 88.7%, and 100% in categories I, II, III, IV, V, and VI, respectively. The most common malignant tumor in category III was salivary duct carcinoma (37.5%), followed by acinic cell carcinoma (25.0%), mucoepidermoid carcinoma (25.0%), and squamous cell carcinoma (12.5%). The 5-year survival rate of patients with malignant tumors showed no statistical difference between category III and category V/VI (P = .140). Risk of malignancy was 88.9% and 100% in category V and VI, respectively. CONCLUSIONS A half of atypia of undetermined significance (category III) cases were malignant. Once diagnosed, the prognosis of malignant tumor in category III was similar with that in category V/VI.

Abstract
BACKGROUND AND PURPOSE The objective of this study was to investigate the association between body mass index (BMI) and both initial stroke severity at presentation and functional outcomes after acute ischaemic stroke (AIS) in patients with non-valvular atrial fibrillation (NVAF). METHODS Patients were categorized on the basis of their BMI into underweight (BMI <18.5, n = 111), normal (18.5 ≤ BMI <25, n = 1036) and overweight to obese (BMI ≥25, n = 472) groups. Initial stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS) score and functional outcomes were assessed using the modified Rankin Scale score at discharge. The differences in stroke severity and functional outcomes were compared between groups using robust log-linear regression with a Poisson distribution and binary logistic regression analysis. RESULTS A total of 1619 AIS patients with NVAF from six hospitals were included. Compared with the NIHSS scores [median 5, interquartile range (IQR) 2-14] of normal-weight patients, the NIHSS scores (median 9, IQR 4-19) of underweight patients were more likely to be higher, whereas those of overweight to obese patients were lower (median 4, IQR 1-12) (P < 0.001). In terms of functional outcomes after stroke, underweight patients had a higher risk of poor functional outcomes (odds ratio 1.78, 95% confidence interval 1.09-2.56, P = 0.01) but overweight to obese patients had no significant difference in functional outcomes compared with normal-weight patients. CONCLUSION An inverse association was found between BMI and stroke severity in AIS patients with NVAF. This suggests the presence of an obesity paradox for short-term outcomes in patients with NVAF.

Abstract
Objectives To evaluate the feasibility of brachial plexus schwannoma enucleation under intraoperative neuromonitoring. Methods Five patients who were treated for brachial plexus schwannoma under intraoperative neuromonitoring from 2008 to 2018 were included in this retrospective review. Neuromonitoring was performed with a 100-μV event threshold of the neuromonitoring system (NIM-2 or 3) at the deltoid, biceps brachii, triceps brachii, and brachioradialis muscles. Patient characteristics, tumor size and location, intraoperative neuromonitoring findings, and postoperative function were evaluated. Results The intraoperative neuromonitoring findings were in accordance with the preoperative assessment of the included nerve root. Three patients had no postoperative morbidity, one patient had temporary paresthesia of the forearm for 2 months, and one patient mild loss of grip strength for 1 month. Conclusion Intraoperative neuromonitoring of the arm and forearm muscles during enucleation of brachial plexus schwannoma promoted confident and successful surgery with minimal postoperative morbidity.

Abstract
OBJECTIVE The purpose of this prospective study was to identify preoperative predictors of unstable exposure of vocal folds with focus on the anterior commissure (AC) prior to Laryngeal Microscopic Surgery. METHODS AND MATERIALS Patients were classified into four groups based on the degree of AC exposure during Laryngeal Microscopic Surgery, and for the analysis, these groups were subdivided into unstable exposure and stable exposure subgroups depending on whether external manipulation was required to achieve AC exposure. Correlation of the degree of AC exposure with demographics, physical measurements, and anatomical measurements taken using landmarks in simple radiograph were evaluated. Receiver operating characteristic curve analysis was used to determine optimal cutoff values to predict unstable AC exposure. RESULTS Fifty-nine patients were included in the analyses. Thyroid-mandible angle (TMA) in the extended position, thyroid-mental distance (TMD) ratio, and TMA difference in the neutral and extended positions were significantly correlated with the degree of AC exposure. However, only a TMD ratio of <1.25 reliably predicted unstable AC exposure. CONCLUSIONS TMD ratio of <1.25 reliably predicted unstable AC exposure. If there is no increase of the distance between the thyroid notch and the mental prominence (TMD) more than 25% on neck extension, the probability of getting stable exposure of the anterior commissure is low.

Abstract
BACKGROUND Cancers of the thyroid isthmus are less frequent compared with the lobar cancers yet have their own unique clinicopathological characteristics. Herein, we sought to examine the isthmic papillary thyroid carcinomas (PTCs) for the pattern of and risk factors for nodal metastasis and the significance of extrathyroidal extension (ETE). METHODS The medical records of 3138 patients diagnosed with solitary PTC who had undergone surgery were retrospectively reviewed. Of these, 122 isthmic PTCs were matched to common lobar PTCs at a ratio of 1:3 for age, sex, and nodule size. Patient demographics, surgical findings, and pathology reports were analyzed. RESULTS Isthmic PTCs comprised 4.6% of all PTCs and had more lymphatic invasion (22.1% vs. 13.4%, p = 0.021), ETE (73.0% vs. 57.1%, p = 0.002), and perithyroidal and prelaryngeal node metastasis (18.0% vs. 9.0%, p = 0.006) compared with lobar PTCs. However, there were no significant differences in the rate of central and lateral node metastasis between the two groups. ETE was identified not to be a risk factor for isthmic PTCs for central and lateral node metastasis, in contrast to lobar PTCs in which ETE was a significant risk factor (odds ratio 3.18, 95% confidence interval [CI] 1.89-5.34; and 4.72, 95% CI 1.04-21.41). CONCLUSION The rates of central and lateral node metastasis of isthmic PTCs are comparable with that of lobar PTCs despite a higher rate of ETE in the isthmic counterpart. Although the extent of surgery for isthmic PTCs remains to be investigated, careful dissection of perithyroidal and prelaryngeal nodes may be necessary for isthmic PTCs.

Abstract
BACKGROUND Nontuberculous mycobacteria (NTM) lymphadenitis is an under-recognized entity, and data of the true burden in children are limited. Without a high index of suspicion, diagnosis may be delayed and microbiological detection is challenging. Here, we report a cluster of NTM lymphadenitis experienced in Korean children. METHODS Subjects under 19 years of age diagnosed with NTM lymphadenitis during November 2016-April 2017 and April 2018 were included. Electronic medical records were reviewed for clinical, laboratory and pathological findings. Information regarding underlying health conditions and environmental exposure factors was obtained through interview and questionnaires. RESULTS A total of ten subjects were diagnosed during 18 months. All subjects were 8-15 years of age, previously healthy, male and had unilateral, nontender, cervicofacial lymphadenitis for more than 3 weeks with no significant systemic symptoms and no response to empirical antibiotics. Lymph nodes involved were submandibular (n = 8), preauricular (n = 6) and submental (n = 1). Five patients had two infected nodes and violaceous discoloration was seen in seven subjects. Biopsy specimens revealed chronic granulomatous inflammation and acid-fast bacteria culture identified Mycobacterium haemophilum in two cases and NTM polymerase chain reaction was positive in two cases. Survey revealed various common exposure sources. CONCLUSION NTM lymphadenitis is rare but increasing in detection and it may occur in children and adolescents. Diagnosis requires high index of suspicion and communication between clinicians and the laboratory is essential for identification of NTM.

Abstract
BACKGROUND AND PURPOSE Several reports suggested that radiotherapy (RT) was related to an increased risk of cerebrovascular disease (CVD) in head and neck cancer (HNC) patients, but other risk factors of CVD were not properly considered in estimating the risk of RT. The purpose of this study is to analyze the effect of RT on the risk of CVD in HNC patients. MATERIALS AND METHODS The Korean Central Cancer Registry data and Korean National Health Insurance Service data were used. A total of 5570 patients with newly diagnosed HNC between the years 2003-2005 was included in our study cohort. We analyzed the effect of treatment modality and other socioeconomic variables on ischemic CVD incidence using the Cox proportional hazard regression model both in the entire cohort (n = 5570) and in the propensity score matching (PSM) cohort (n = 3310). RESULTS RT increased the CVD risk by 40.8% (aHR: 1.408, p = 0.006) in the entire cohort and by 44.3% (aHR: 1.443, p = 0.047) in the PSM cohort, respectively. CONCLUSION The risk of ischemic CVD increased by RT after adjusting for other socioeconomic and clinical risk factors. Regular follow up and appropriate screening for CVD are required for HNC patients who received RT, and focus should be on advanced-age patients with a low socioeconomic status and known clinical risk factors of CVD.

Abstract
BACKGROUND Distant metastasis of adenoid cystic carcinoma (ACC) is most commonly identified in the lung, but risk factors are still on debate. METHODS Risk factors for lung metastasis were evaluated by using Cox proportional hazards model and Kaplan-Meier curves. RESULTS Of 112 patients, 48% had distant metastasis; 94.4% of whom had lung metastasis. Univariable analysis revealed sublingual or minor salivary gland, tumor size ≥2.5 cm, and perineural invasion as risk factors (hazard ratio [HR]: 1.99 [1.02-3.91], 2.57 [1.19-5.58], and 2.46 [1.28-4.74], respectively), whereas size, perineural invasion, and local recurrence were risk factors in multivariable analysis (HR: 2.29 [1.05-4.96], 2.32 [1.09-4.96], and 2.68 [1.24-5.79], respectively). CONCLUSION Sublingual gland or minor salivary glands ACC has a higher risk of lung metastasis. If the site is not considered, the following factors increased the risk of lung metastasis; (a) size ≥2.5 cm, (b) perineural invasion, and (c) local recurrence.

Abstract
BACKGROUND Post-thyroidectomy hematoma (PH) is uncommon but may be a life-threatening complication. We explored perioperative risk factors for PH, with emphasis on perioperative hemodynamics, pain, and medications. METHODS A retrospective case-control study was performed with matching for age, sex, and type of operation. Univariate and multivariate analyses were performed to identify independent risk factors. RESULTS In 1780 thyroid surgeries, 22 cases of PH were detected (1.24%). Antithrombotic agent usage, numeric rating scale (NRS) of postoperative pain, and two or more doses of ketorolac postoperatively significantly differed between the two groups. Multiple regression analysis revealed all three variables were significant risk factors for PH (odds ratio = 55.23, 10.48, and 22.58, respectively). Perioperative hemodynamics did not affect PH. CONCLUSIONS Antithrombotic agent usage, postoperative pain, and two or more doses of ketorolac postoperatively were identified as independent risk factors for PH. Proper pain control and judicious usage of ketorolac are recommended.

Abstract
Carcinoma ex pleomorphic adenoma (CXPA) arises from the primary or recurrent benign pleomorphic adenoma. The purpose of this study was to evaluate the clinical features that could be referenced in the differentiation. The medical records of 221 patients with pleomorphic adenoma and 15 patients with CXPA were retrospectively reviewed. Clinical characteristics, computed tomography and magnetic resonance imaging findings, and surgical pathology were analyzed. Patients with CXPA were older (55.1 vs 42.3; P < .01). Carcinoma ex pleomorphic adenoma was observed at higher rates in the minor salivary glands (24.9% vs 2.7%) and higher incidence of regional lymph node enlargement (P = .04). While all CXPA showed a low-to-intermediate mean apparent diffusion coefficient value (ADC), most of pleomorphic adenoma had an intermediate-to-high (P = .01). From this study, the following features should be considered as the clinical features of CXPA: (1) old age; (2) minor salivary gland tumor; (3) regional lymph node enlargement (>5 mm); and (4) low ADC findings.

Abstract
PURPOSE This study reports the clinical course, including the growth rate, of Warthin's tumor (WT) and evaluates the positive prediction of needle biopsy for WT. METHODS The medical records of 182 patients clinically diagnosed with WT were retrospectively reviewed. Tumor growth rates were measured in patients who underwent serial radiologic exams with minimum 6-month time intervals, and the positive prediction value (PPV) of needle biopsy was evaluated in comparison with surgical pathology in patients who underwent surgical excision of the tumors. RESULTS Serial radiologic exams were available for growth rate measurement in 31 tumors (size 0.7-9.1 cm) from 25 patients. Among these, 24 tumors increased in size, and 7 were stable. The median follow-up duration was 23.5 months [interquartile range (IQR) 14.8-51.9], and the tumor growth rate ranged from - 0.36 to 2.26 cm per year (median 0.26, IQR 0.07-0.44). Needle biopsy results were available for comparison with postoperative pathology specimens in 147 patients. The PPV was 97.7% for fine-needle aspiration biopsy and 100% for core-needle biopsy. There were no reports of inflammation, facial nerve paralysis, or admission event during the follow-up. CONCLUSIONS WT glows slowly and can be predicted by needle biopsy. Therefore, parotid masses diagnosed as Warthin's tumor can be treated or left untreated based on the patient's needs and clinical decision-making.

Abstract
BACKGROUND Interface fluid syndrome (IFS) is an unusual complication after laser-assisted in-situ keratomileusis (LASIK). We report the first case of IFS after uncomplicated phacotrabeculectomy in a patient who had undergone LASIK 10 years previously. This case emphasizes the importance of intraocular pressure (IOP) interpretation in eyes that have undergone LASIK. CASE PRESENTATION A 30-year-old woman with a history of LASIK surgery presented to glaucoma clinic due to uncontrolled IOP despite of maximally tolerable medical treatment. After receiving phacotrabeculectomy, IOP decreased to 3 mmHg on the first postoperative day, but again increased up to 21 mmHg and a diffuse corneal edema with cloudy flap interface was demonstrated by slit-lamp microscopy. Corneal edema was sustained even after the IOP was lowered to 14 mmHg. Spectral-domain optical coherence tomography scanning of the cornea revealed a diffuse, thin fluid pocket in the corneal interface. After laser lysis of the scleral flap sutures, IOP was further decreased to 9 mmHg and interface fluid was resolved. CONCLUSION IFS should be considered as a possible cause of postoperative corneal edema despite of low IOP in the eyes that underwent LASIK surgery. Additional IOP lowering may be helpful for resolving the corneal edema.

Abstract
Lessons Learned. Induction chemotherapy with Genexol‐PM and cisplatin demonstrated modest tumor response in locally advanced head and neck squamous cell carcinoma. Considering favorable toxicity profiles and promising survival data, further studies on this regimen are warranted in patients with head and neck squamous cell carcinoma.
Background. Genexol‐PM is a polymeric micellar formulation of paclitaxel without Cremophor EL. We investigated the efficacy and safety of Genexol‐PM plus cisplatin as induction chemotherapy (IC) in patients with locally advanced head and neck squamous cell carcinoma (LA‐HNSCC). Methods. Patients received Genexol‐PM (230 mg/m2) and cisplatin (60 mg/m2) every 3 weeks as IC. After three cycles of IC, definitive treatment of either concurrent chemoradiotherapy (CCRT) with weekly cisplatin (30 mg/m2) or surgery was performed. The primary endpoint was overall response rate (ORR) after IC. Results. Of 52 patients enrolled, 47 completed three cycles of IC, and the ORR was 55.8% (95% confidence interval, 42.3–69.3). Although there was one treatment‐related death, toxicity profiles to Genexol‐PM and cisplatin were generally favorable, and the most common grade 3 or 4 toxicities were neutropenia (15.4%), anorexia (7.7%), and general weakness (7.7%). Fifty‐one patients received definitive treatment (CCRT [n = 44] or radical surgery [n = 7]). The rate of complete response following CCRT was 81.8% (36/44). After a median follow‐up of 39 months, estimates of progression‐free survival (PFS) and overall survival (OS) at 3 years were 54.3% and 71.3%, respectively. Conclusion. IC with Genexol‐PM and cisplatin demonstrated modest tumor response with well‐tolerated toxicity profiles for patients with LA‐HNSCC.

Abstract
OBJECTIVE The aim of this study was to evaluate the treatment outcomes for stage III/IV locally advanced hypopharyngeal squamous cell carcinoma (SCC), comparing induction chemotherapy followed by (chemo)radiotherapy (ICT), definitive chemoradiotherapy (CRT) and surgery-based therapy (SRT). SUBJECTS AND METHODS Two hundred sixty-six patients with stage III/IV locally advanced hypopharyngeal squamous cell carcinoma (SCC) who underwent ICT (n = 74), CRT (n = 53) or SRT (n = 139) from 1997 through 2014 at the Seoul National University Hospital (n = 127) and the Hallym University Medical Center (n = 139) were enrolled in the study. All surgical procedures in the SRT group were performed by a single surgeon to eliminate surgeon bias. RESULTS The 5-year disease-free survival (DFS) and overall survival (OS) of all patients (n = 266) were 59.4% and 44%, respectively. The 5-year DFS rates after salvage treatment were 52.7% for ICT, 52.8% for CRT and 65.5% for SRT (p = 0.194). The OS rates were 44.6% for ICT, 39.6% for CRT and 45.3% for SRT group (p = 0.106). The salvage rates were 12.5% for ICT, 15.6% for CRT and 3.8% for SRT group. The final laryngeal preservation rate was significantly lower in the SRT group (44.6%) than in the ICT (71.6%) or CRT (71.7%) groups. All major postoperative complications were significantly higher in the salvage surgery group. CONCLUSION Treatment outcomes in the ICT and CRT groups were comparable to that of the SRT group for stage III/IV hypopharyngeal SCC. However, the relatively low chance of cure and high risk of complications should be taken into account when considering salvage surgery.

Abstract
PURPOSE To evaluate the prognostic value of 18F-fluorodeoxyglucose positron-emission tomography (FDG PET) with computed tomography (CT) before and during radiotherapy (RT) in patients with head and neck cancer. METHODS Twenty patients with primary head and neck squamous cell carcinoma were enrolled in this study, of whom 6 had oropharyngeal cancer, 10 had hypopharyngeal cancer, and 4 had laryngeal cancer. Fifteen patients received concurrent cisplatin and 2 received concurrent cetuximab chemotherapy. FDG PET/CT was performed before RT and in the 4th week of RT. The parameters of maximum standardized uptake value, metabolic tumor volume, and total lesion glycolysis (TLG) of the primary tumor were measured, and the prognostic significance of each was analyzed with the Cox proportional hazards model. RESULTS Higher TLG (>19.0) on FDG PET/CT during RT was a poor prognostic factor for overall survival (OS) (p = 0.001) and progression-free survival (PFS) (p = 0.007). In the multivariate analysis, TLG during RT as a continuous variable was significantly associated with OS and PFS rate (p = 0.023 and p = 0.016, respectively). Tumor response worse than partial remission at 1 month after RT was another independent prognostic factor for PFS (p = 0.024). Conclusions: Higher TLG of the primary tumor on FDG PET/CT during RT was a poor prognostic factor for OS and PFS in patients with head and neck cancer.

Abstract
Epidemiological studies have shown that exposure to tobacco smoke causing irritation and inflammation in the airways tends to reduce serum periostin concentrations in adults. We now investigate prospective cross-sectional study on 135 Korean students aged 7 years in the first grade who were participating in the Seongnam Atopy Project for Children's Happiness 2016 (SAP₂₀₁₆) cohort. To the best of our knowledge, this is the first study to show significant inverse correlations between serum periostin concentration and exposure to xylene and formaldehyde in children. Our findings suggested the need for caution in using the serum periostin level as a marker for allergic diseases, since exposure to volatile organic compounds and formaldehyde may confound the interpretation of these results.

Abstract
Objective To determine the dose of remifentanil needed to achieve successful insertion of the Streamlined Liner of the Pharyngeal Airway (SLIPA™) without the development of hypertension in 95% of the patients. Design Randomised controlled trial. Setting operating theatre of a university hospital Methods A total of 100 ASA I or II patients requiring SLIPA insertion were randomly assigned to receive normal saline (Group C) or one of the four different doses (0.5 µg/kg [Group R0.5], 1.0 µg/kg [Group R1], 1.5 µg/kg [Group R1.5] or 2.0 µg/kg [Group R2]) of remifentanil. Arterial blood pressure and heart rate were recorded at preanesthetic baseline, preinserton, and every one minute during the initial 3 minutes period after insertion. Results A Probit model of remifentanil concentration was predictive of successful insertion of SLIPA without the development of hypertension. The ED95 of remifentanil needed to suppress haemodynamic response from SLIPA insertion was 1.39 µg/kg (95% confidence interval, 1.06-2.61 µg/kg). Conclusions A single administration of remifentanil can effectively suppress haemodynamic changes due to the insertion of SLIPA.

Abstract
Introduction Streamlined Liner of the Pharynx Airway (SLIPA) is a disposable supraglottic airway. There are two strategies to select the size of SLIPA: by height and width of thyroid cartilage. This study compared the utility of the two strategies in selecting the optimal size. Methods One hundred forty-two patients were randomly divided into two groups with size selection by height (H) and the maximal width of the thyroid cartilage (T). The SLIPA size was selected by height in group H, and by the width of thyroid cartilage in group T. After inserting SLIPA, the investigator made note of the oropharyngeal leakage pressure (OLP) and the degree of insertion difficulty. We set the OLP as a primary outcome. In cases of an OLP <15 cmH2O, the investigator manipulated the apparatus to try to reposition it. If air still leaked, another attempt was made using a SLIPA one size larger until an OLP >15 cmH2O was achieved in up to three attempts. After insertion, the investigator measured the inspiratory and expiratory tidal volume. Post-operatively, the presence of blood or regurgitated fluid on the device was evaluated. Results OLP for group T was higher than that of group H (p=0.009). The need for manipulation and the leak fraction was higher in group H than in group T (p=0.008 and 0.034, respectively). The degree of insertion difficulty, number of trials and incidence of blood and regurgitated fluid on the device were similar between the two groups. Conclusions Both the width and height of thyroid cartilage can be used for selecting the optimal SLIPA size. (Hong Kong j.emerg.med. 2015;22:303-311)

Abstract
Purpose: Head and neck squamous cell carcinoma (HNSCC) is comprised of heterogeneous populations of cells, and CD271 (NGFR; p75NTR) has been associated with a tumor-initiating cell subpopulation. This study assessed the role of CD271 in modulating metastatic behavior in HNSCC.Experimental Design: CD271 was overexpressed in murine and human oral squamous cell carcinoma cells to assess the impact of CD271 activation on the invasive and metastatic phenotype of these cells, using in vitro and orthotopic in vivo modeling. Treatment with human nerve growth factor (NGF) to activate CD271, as well as shRNA knockdown of the CD271-upregulated Snai2 expression, was used to assess the mechanism of the CD271-induced invasive phenotype. Relevance of CD271 expression in human HNSCC was evaluated in patient-derived xenografts (PDX) and primary human oral cancers, annotated with clinical behavior characteristics and survival data.Results: Forced expression of CD271 resulted in a more invasive and metastatic phenotype. Slug, an epithelial-to-mesenchymal transition (EMT)-related transcription factor, encoded by Snai2, was highly expressed in MOC2-CD271 and HSC3-CD271, compared with respective parental cells. CD271 activation by NGF conferred enhanced invasiveness in CD271-overexpressing cells, which was abrogated by Snai2 knockdown. In PDXs and primary human HNSCC, CD271 expression correlated with higher Snai2 expression, greater nodal metastasis, and shorter disease-free survival.Conclusions: Activation of CD271 results in upregulation of Snai2/Slug, which, in turn, results in a more invasive phenotype and an enhanced capacity for metastasis to regional lymph nodes. These findings point to CD271 as a promising, therapeutic target for oral cancer metastasis. Clin Cancer Res; 24(3); 674-83. ©2017 AACR.

Abstract
BACKGROUND Serum periostin might be a biomarker in the pathogenesis of T helper 2-type allergic diseases. The aim of this study was to investigate the relationship between serum periostin levels and the severity and chronicity of atopic dermatitis (AD) in children. METHODS This population-based study examined 4076 children aged 4 to 13 years between June 2015 and July 2015. Of the 4076 children, 196-137 with a history of AD in the AD group and 59 without allergic diseases history in the healthy control (HC) group-were included for the final analysis. RESULTS Serum periostin levels were higher in the AD group than in the HC group (P<.001) and were found to be positively associated with SCORAD score (Spearman's rho [r]=.24, P=.001). Children with AD-onset time <2 years had significantly higher periostin levels (P=.030) compared to those with AD-onset time ≥2 years. The total eosinophil (P=.189) and IgE levels (P=.140) were comparable between children with AD-onset time <2 years and those with AD-onset time ≥2 years. After adjustment for age, gender, and parental allergic history, serum periostin level (OR: 1.03, 95% CI: 1.00-1.06, P=.046) contributed to the development of AD in children with AD-onset time <2 years. CONCLUSION Serum periostin level may play a role in the severity and chronicity of AD in children.

Abstract
Purpose Chest radiography is often performed on patients hospitalized with typical clinical manifestations of bronchiolitis. We aimed to determine the proportion of subjects with pathologic chest radiographic findings and the clinical predictors associated with pathologic chest radiographic findings in young children admitted with the typical presentation of bronchiolitis. Methods We obtained the following data at admission: sex, age, neonatal history, past history of hospitalization for respiratory illnesses, heart rate, respiratory rate, the presence of fever, total duration of fever, oxygen saturation, laboratory parameters (i.e., complete blood cell count, high-sensitivity C-reactive protein [hs-CRP], etc.), and chest radiography. Results The study comprised 279 young children. Of these, 26 had a chest radiograph revealing opacity (n=24) or atelectasis (n=2). Multivariate logistic regression analysis showed that after adjustment for confounding factors, the clinical predictors associated with pathologic chest radiographic findings in young children admitted with bronchiolitis were elevated hs-CRP level (>0.3 mg/dL) and past history of hospitalization for respiratory illnesses (all P<0.05). Conclusion The current study suggests that chest radiographs in young children with typical clinical manifestations of bronchiolitis have limited value. Nonetheless, young children with clinical factors such as high hs-CRP levels at admission or past history of hospitalization for respiratory illnesses may be more likely to have pathologic chest radiographic findings.

Abstract
Purpose Limited data is available on the prevalence and risk factors of acute and chronic urticaria in children. Our purpose was to determine the prevalence and identify the risk factors of acute and chronic urticaria in Korean children. Methods This population-based study examined 4,076 children (age 4 to 13 years) who were enrolled in the 2015 prospective Seongnam Atopy Project (SAP 2015) in Korea. The parents completed an urticaria questionnaire that included questions regarding the duration, severity, and triggering factors of urticaria. Blood sampling (n=464) was performed to measure vitamin D, total eosinophil count (TEC), and total IgE levels, and skin prick tests (n=503) were done. Results The prevalences of the life-time, acute, and chronic urticaria were 22.5%, 13.9%, and 1.8% (chronic continuous urticaria, 0.7%; and chronic recurrent urticaria, 1.1%), respectively. Acute urticaria was significantly associated with allergic diseases and parental history of allergy (P<0.001), but chronic urticaria was not associated with these clinical factors. There was no significant difference in the 25-hydroxyvitamin D level between subjects with chronic urticaria and controls (P=0.124). Chronic continuous urticaria was associated with living in a new residence (aOR=2.38, 95% CI=1.02-5.54, P=0.044) and belonging to a family with a high income (aOR=4.24, 95% CI=1.24-14.56, P=0.022). Conclusions A total of 1.8% of children were found to have chronic urticaria. Living in a new residence and belonging to a family with a high income increased the risk of chronic continuous urticaria.

Abstract
PURPOSE The nature of allergic rhinitis (AR) in preschool aged children remains incompletely characterized. This study aimed to investigate the prevalence of AR and its associated risk factors in preschool-aged children and to assess the clinical utility of fractional exhaled nitric oxide (FeNO). METHODS This general population-based, cross-sectional survey included 933 preschool-aged (3- to 7-year-old) children from Korea. Current AR was defined as having nasal symptoms within the last 12 months and physician-diagnosed AR. RESULTS The prevalence of current AR in preschool children was 17.0% (156/919). Mold exposure (adjusted odds ratio [aOR], 1.67; 95% confidence interval [CI], 1.15-2.43) and the use of antibiotics (aOR, 1.97; 95% CI, 1.33-2.90) during infancy were associated with an increased risk of current AR, whereas having an older sibling (aOR, 0.52; 95% CI, 0.35-0.75) reduced the risk. Children with current atopic AR had significantly higher geometric mean levels of FeNO compared to those with non-atopic rhinitis (12.43; range of 1standard deviation [SD], 7.31-21.14 vs 8.25; range of 1SD, 5.62-12.10, P=0.001) or non-atopic healthy children (8.58; range of 1SD, 5.51-13.38, P<0.001). The FeNO levels were higher in children with current atopic AR compared with atopic healthy children (9.78; range of 1SD, 5.97-16.02, P=0.083). CONCLUSIONS Mold exposure and use of antibiotics during infancy increases the risk of current AR, whereas having an older sibling reduces it. Children with current atopic AR exhibit higher levels of FeNO compared with non-atopic rhinitis cases, suggesting that FeNO levels may be a useful discriminatory marker for subtypes of AR in preschool children.

Abstract
Purpose To investigate the incidence of neovascularization of the iris (NVI) and clinical features of patients with NVI following acute central retinal artery occlusion (CRAO). Methods A retrospective review of 214 consecutive CRAO patients who visited one tertiary hospital between January 2009 and January 2015 was conducted. In total, 110 patients were eligible for this study after excluding patients with arteritic CRAO, a lack of follow-up, iatrogenic CRAO secondary to cosmetic filler injection, or NVI detected before CRAO attack. Fluorescein angiography (FA) was applied until retinal arterial reperfusion was achieved, typically within 1 to 3 months. Results The incidence of NVI was 10.9% (12 out of 110 patients). Neovascular glaucoma was found in seven patients (6.4%). The mean time to NVI diagnosis after CRAO events was 3.0 months (range, 1 week to 15 months). The cumulative incidence was 5.5% at 3 months, 7.3% at 6 months, and 10.9% at 15 months. Severely narrowed ipsilateral carotid arteries were observed in only three patients (27.3%). The other nine patients (75.0%) showed no predisposing conditions for NVI, such as proliferative diabetic retinopathy or central retinal vein occlusion. Reperfusion rate and prevalence of diabetes were significantly different between patients with NVI and patients without NVI (reperfusion: 0% [NVI] vs. 94.7% [no NVI], p < 0.001; diabetes: 50.0% [NVI] vs. 17.3% [no NVI], p = 0.017). Conclusions CRAO may lead to NVI and neovascular glaucoma caused by chronic retinal ischemia from reperfusion failure. Our results indicate that follow-up fluorescein angiography is important to evaluate retinal artery reperfusion after acute CRAO events, and that prophylactic treatment such as panretinal photocoagulation should be considered if retinal arterial perfusion is not recovered.

Abstract
Microbial colonization of the infant gut is unstable and shows a wide range of diversity between individuals. Gut microbiota play an important role in the development of the immune system, and an imbalance in these organisms can affect health, including an increased risk of allergic diseases. Microbial colonization of young infants is affected by the delivery mode at birth and the consequent alterations of gut microbiota in early life affect the development of allergic diseases. We investigated the effects of the delivery mode on the temporal dynamics of gut microbiota in healthy Korean infants. Fecal samples were collected at 1-3 days, 1 month, and 6 months after birth in six healthy infants. Microbiota were characterized by 16S rRNA shotgun sequencing. At the first and third days of life, infants born by vaginal delivery showed a higher richness and diversity of gut microbiota compared with those born by cesarean section. However, these differences disappeared with age. The Bacteroides genus and Bacteroidetes phylum were abundant in infants born by vaginal delivery, whereas Bacilli and Clostridium g4 were increased in infants born by cesarean section. The Firmicutes phylum and Bacteroides genus showed convergent dynamics with age. This study demonstrated the effect of delivery mode on the dynamics of gut microbiota profiles in healthy Korean infants.

Abstract
This research investigates plasma-treated and metal-coated carbon nanowalls (CNWs) for use as counter electrodes of dye-sensitized solar cells (DSSCs). The CNWs were synthesized on a fluorine-tin-oxide (FTO) glass substrate using the microwave plasma-enhanced chemical vapor deposition (PECVD) system with methane (CH4) gas. The post-plasma treatment was performed on the CNWs with hydrogen (H2) plasma using PECVD, and the CNWs were sputter-coated with metal films using the RF magnetron sputtering system with a four-inch tungsten (W) target. Then the post-plasma-treated and metal-coated CNWs were used as counter electrodes for the fabrication of the DSSCs. Field-emission scanning electron microscopy (FE-SEM) was performed to obtain cross-sectional and planar images of the grown CNWs. The energy conversion efficiencies of the DSSCs manufactured using the post-plasma-treated and metal-layer-coated CNWs as the counter electrodes were measured.

Abstract
Purpose Nonallergenic irritants can aggravate the symptoms of rhinitis. We investigated the clinical responses of children with allergic rhinitis (AR) and nonallergic rhinitis (NAR) to nonallergenic irritants, and identified factors associated with these responses. Methods Children with chronic rhinitis (n=208) were classified as having AR or NAR based on the presence of aeroallergen-specific IgE. Healthy controls (n=24) were recruited for comparison. The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines were used to classify patients, and their irritant score (0-21 points) and current symptom score (5-35 points) were measured. Subjects with irritant scores ≥3 and <3 were classified as having irritant and nonirritant rhinitis, respectively. Results The mean age of enrolled subjects was 6.8 years (range: 1.8-16.0 years). The AR and NAR groups had similar irritant scores (P=0.394) and proportions of subjects with irritant scores ≥3 (P=0.105). Irritant score correlated positively with symptom score (P=0.005), and the proportion of subjects with irritant scores ≥3 was greater in children with moderate-severe rhinitis than in those with mild rhinitis (P=0.046). Multiple logistic regression analysis indicated that the presence of atopic eczema increased the risk for sensitivity to a nonallergenic irritant (aOR=2.928, 95% CI 1.567-5.473, P=0.001). Conclusions Response to a nonallergenic irritant was useful for gauging the severity of rhinitis, but not for differentiating AR from NAR. AR and NAR patients with atopic eczema may increase nasal sensitivity to nonallergenic irritants.

Abstract
Oxygen signaling is critical for stem cell regulation, and oxidative stress-induced stem cell apoptosis decreases the efficiency of stem cell therapy. Hypoxia activates O-linked β-N-acetyl glucosaminylation (O-GlcNAcylation) of stem cells, which contributes to regulation of cellular metabolism, as well as cell fate. Our study investigated the role of O-GlcNAcylation via glucosamine in the protection of hypoxia-induced apoptosis of mouse embryonic stem cells (mESCs). Hypoxia increased mESCs apoptosis in a time-dependent manner. Moreover, hypoxia also slightly increased the O-GlcNAc level. Glucosamine treatment further enhanced the O-GlcNAc level and prevented hypoxia-induced mESC apoptosis, which was suppressed by O-GlcNAc transferase inhibitors. In addition, hypoxia regulated several lipid metabolic enzymes, whereas glucosamine increased expression of glycerol-3-phosphate acyltransferase-1 (GPAT1), a lipid metabolic enzyme producing lysophosphatidic acid (LPA). In addition, glucosamine-increased O-GlcNAcylation of Sp1, which subsequently leads to Sp1 nuclear translocation and GPAT1 expression. Silencing of GPAT1 by gpat1 siRNA transfection reduced glucosamine-mediated anti-apoptosis in mESCs and reduced mammalian target of rapamycin (mTOR) phosphorylation. Indeed, LPA prevented mESCs from undergoing hypoxia-induced apoptosis and increased phosphorylation of mTOR and its substrates (S6K1 and 4EBP1). Moreover, mTOR inactivation by rapamycin (mTOR inhibitor) increased pro-apoptotic proteins expressions and mESC apoptosis. Furthermore, transplantation of non-targeting siRNA and glucosamine-treated mESCs increased cell survival and inhibited flap necrosis in mouse skin flap model. Conversely, silencing of GPAT1 expression reversed those glucosamine effects. In conclusion, enhancing O-GlcNAcylation of Sp1 by glucosamine stimulates GPAT1 expression, which leads to inhibition of hypoxia-induced mESC apoptosis via mTOR activation.

Abstract
Background Although chronic obstructive pulmonary disease (COPD) is closely associated with gastroesophageal reflux disease (GERD), the clinical significance of laryngopharyngeal reflux (LPR) is not fully understood in COPD. Methods Prospective cohorts were established among 118 patients with COPD from March 2013 to July 2014. Thirty-two age-matched and sex-matched normal controls, who had routine health check-ups during the study period, were included. Laryngopharyngeal reflux finding scores (RFS) and reflux symptom index (RSI) for LPR were subjected to association analysis with severity and acute exacerbation of COPD during the 1-year follow-up. Results The mean age of patients enrolled in the study was 69.2±8.8 years, with 93.2% being male. Positive RFS (>7) and RSI (>13) were observed in 51 (42.5%) and six patients (5.0%), respectively. RFS and RSI were significantly higher in patients with COPD than in normal, healthy patients (P<0.001). RFS was significantly correlated with residual volume/total lung capacity (%, P=0.048). Scores for diffuse laryngeal edema, erythema, and hyperemia were significantly higher in the high-risk group (Global Initiative for Chronic Obstructive Lung Disease classification C and D; P=0.025 and P=0.049, respectively), while RSI was significantly higher in the more symptomatic group (Global Initiative for Chronic Obstructive Lung Disease classification B and D; P=0.047). RSI and RFS were significant predictors for severe acute exacerbation of COPD (P=0.03 and P=0.047, respectively), while only RSI was associated with severity of dyspnea. Conclusion Laryngeal examination and evaluation of laryngeal reflux symptom could be a surrogate clinical indicator related to severe acute exacerbation of COPD. Further studies of LPR in COPD patients should be considered.
