ABSTRACT
Background@#Despite the extraordinary speed of mass vaccination efforts, an outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) delta variant in a vaccinee with coronavirus disease 2019 (COVID-19) mRNA vaccine was identified in an adult day service center (ADSC) of Jeju, South Korea. The primary objective of this study was to investigate the epidemiologic features in infection-vulnerable facilities with a high vaccination rate of BNT162b2 mRNA COVID-19 vaccine. The second was to estimate the secondary transmission prevention effect of the vaccine in the household members by vaccination status. @*Methods@#We included all ADSC participants, staff and their household members. All COVID-19 infected cases were confirmed by reverse transcriptase polymerase chain reaction.We calculated attack rate in ADSC and the secondary attack rate (SAR) in household members by vaccination status. @*Results@#Among a total of 42 participants and 16 staff, of which 96.6% were fully vaccinated with BNT162b2 mRNA COVID-19 vaccine, 12 symptomatic cases and 13 asymptomatic confirmed cases of COVID-19 were found. The attack rate was 43.1%, with 13 isolates identified as SARS-CoV-2 virus, delta variant. The SAR in unvaccinated and partially vaccinated household members were 27.8% (5/18) and 25.0% (5/20), respectively, while the SAR in fully vaccinated household members was 12.5% (1/8). @*Conclusion@#We describe a SARS-CoV-2 delta variant outbreak in ADSC with high vaccine coverage rate, characterized by high infection rate, high transmissibility, and low clinical severity. The outbreak proceeded to unvaccinated or partially vaccinated household members, emphasizing the need for immunizing close contacts of high-risk groups.
ABSTRACT
Background@#We aim to validate the diagnostic performance of thyroid core needle biopsy (CNB) for diagnosing malignancy in clinical settings to align with the changes made in recently updated thyroid CNB guidelines. @*Methods@#We retrospectively analyzed 1,381 thyroid CNB and 2,223 fine needle aspiration (FNA) samples. The FNA and CNB slides were interpreted according to the Bethesda System for Reporting Thyroid Cytopathology and updated practice guidelines for thyroid CNB, respectively. @*Results@#Compared to FNA, CNB showed lower rates of inconclusive results: categories I (2.8% vs. 11.2%) and III (1.2% vs. 6.2%), and higher rates of categories II (60.9% vs. 50.4%) and IV (17.5% vs. 2.0%). The upper and lower bounds of the risk of malignancy (ROM) for category IV of CNB were 43.2% and 26.6%, respectively. The CNB subcategory IVb with nuclear atypia had a higher ROM than the subcategory without nuclear atypia (40%–62% vs. 23%–36%). In histologically confirmed cases, there was no significant difference in the diagnostic performance between CNB and FNA for malignancy. However, neoplastic diseases were more frequently detected by CNB than by FNA (88.8% vs. 77.6%, P=0.046). In category IV, there was no difference in unnecessary surgery rate between CNB and FNA (4.7% vs. 6.9%, P=0.6361). @*Conclusion@#Thyroid CNB decreased the rate of inconclusive results and showed a higher category IV diagnostic rate than FNA. The revised guidelines for thyroid CNB proved to be an excellent reporting system for assessing thyroid nodules.
ABSTRACT
Objective@#: Cervical surgery in patients with cervical spondylotic myelopathy (CSM) and cerebral palsy (CP) is challenging owing to the complexities of the deformity. We assessed factors affecting postoperative complications and outcomes after CSM surgery in patients with CP. @*Methods@#: Thirty-five consecutive patients with CP and CSM who underwent cervical operations between January 2006 and January 2014 were matched to 35 non-cerebral palsy (NCP) control patients. Postoperative complications and radiologic outcomes were compared between the groups. In the CP group, the Japanese Orthopaedic Association score; Oswestry neck disability index; modified Barthel index; and values for the grip and pinch, Box and Block, and Jebsen-Taylor hand function tests were obtained preand postoperatively and compared between those with and without postoperative complications. @*Results@#: Sixteen patients (16/35%) in the CP group and seven (7/35%) in the NCP group (p=0.021) had postoperative complications. Adjacent segment degeneration (p=0.021), postoperative motor weakness (p=0.037), and revisions (p=0.003) were significantly more frequent in the CP group than in the NCP group; however, instrument-related complications were not significantly higher in the CP group (7/35 vs. 5/35, p=0.280). The number of preoperative fixed cervical deformities were significantly higher in CP with postoperative complications (5/16 vs. 1/19, p=0.037). In the CP group, clinical outcomes were almost similar between those with and without postoperative complications. @*Conclusion@#: The occurrence of complications during the follow-up period was high in patients with CP. However, postoperative complications did not significantly affect clinical outcomes.
ABSTRACT
Background and Objectives@#Fine needle aspiration cytology (FNAC) combined with washout thyroglobulin (Tg) measurement is the gold standard for the evaluation of metastatic lymph nodes (LNs) in thyroid cancer. However, few studies have assessed the clinical outcomes of discordant results between FNAC and washout Tg based on surgery status and follow-up imaging in real-world practice. @*Materials and Methods@#A total of 707 LNs in 512 patients who underwent FNAC and washout Tg measurements from 2015 to 2017 were analyzed. The final LN outcomes were confirmed through postoperative histology, or through metastatic FNAC findings combined with high washout Tg level, follow-up imaging studies, or repeat FNA, if LNs were not dissected. @*Results@#The cut-off values of washout Tg for indicating LN metastasis in preoperative and postoperative LNs were 9.6 ng/mL and 2.1 ng/mL. The diagnostic accuracy was improved by applying washout Tg according to surgery status and the results of discordant rate was reduced, Discordant between results of FNAC with washout Tg and final outcome were 9.2% (27/295) of preoperative LNs and 8.7% (36/412) of postoperative LNs. Due to inconclusive results, unnecessary neck dissection can occur in 13.9% (36/259 dissected cases). @*Conclusion@#To improve diagnostic accuracy, cut-off values of washout Tg should be applied depending on surgery status. New biomarkers in washout fluid is necessary to resolve discordant findings.
ABSTRACT
Background@#Postoperative thyroid stimulating hormone (TSH) suppression therapy is recommended for patients with intermediate- and high-risk differentiated thyroid cancer to prevent the recurrence of thyroid cancer. With the recent increase in small thyroid cancer cases, the extent of resection during surgery has generally decreased. Therefore, questions have been raised about the efficacy and long-term side effects of TSH suppression therapy in patients who have undergone a lobectomy. @*Methods@#This is a multicenter, prospective, randomized, controlled clinical trial in which 2,986 patients with papillary thyroid cancer are randomized into a high-TSH group (intervention) and a low-TSH group (control) after having undergone a lobectomy. The principle of treatment includes a TSH-lowering regimen aimed at TSH levels between 0.3 and 1.99 μIU/mL in the low-TSH group. The high-TSH group targets TSH levels between 2.0 and 7.99 μIU/mL. The dose of levothyroxine will be adjusted at each visit to maintain the target TSH level. The primary outcome is recurrence-free survival, as assessed by neck ultrasound every 6 to 12 months. Secondary endpoints include disease-free survival, overall survival, success rate in reaching the TSH target range, the proportion of patients with major cardiovascular diseases or bone metabolic disease, the quality of life, and medical costs. The follow-up period is 5 years. @*Conclusion@#The results of this trial will contribute to establishing the optimal indication for TSH suppression therapy in low-risk papillary thyroid cancer patients by evaluating the benefit and harm of lowering TSH levels in terms of recurrence, metabolic complications, costs, and quality of life.

ABSTRACT
Background/Objectives@#Although thyroid lobectomy recently is considered as sufficient for low-risk papillary thyroid carcinoma (PTC), completion thyroidectomy is required due to the insufficiency of the preoperative evaluation. The aim of this study was to investigate recurrence rate and disease free survival depending on the gross extrathyroidal extension (gETE) or the number of metastatic lymph node identified in patients with PTC.Materials & Methods: We assessed 3373 patients with PTC who underwent lobectomy at Seoul St. Mary’s Hospital (Seoul, Korea) between January 2009 and December 2014. Clinicopathological characteristics and long-term surgical outcomes were retrospectively analyzed through complete chart reviews. The mean follow-up duration was 97.1 ± 21.4 months. @*Results@#The rate of recurrence was higher in gETE group (1.8% vs. 6.0%, p=0.004), leading to decreased disease free survival in Kaplan-Meier analysis (log-rank p<0.001). N1 group (n=1389) was analyzed into two groups whether the number of positive nodes is more than 5 or less. For the group of the more metastatic nodes, the recurrence rate higher compared to the other group (3.0% vs. 9.3%, p<0.001). DFS was longer in the group that had lesser metastatic nodes (log-rank p<0.001). However, in terms of N1 group over 1cm (n=492), No statistical difference was observed according to the number of positive lymph nodes (4.5% vs. 9.1%, p=0.092) @*Conclusion@#When it comes to node positive PTC, Despite the number of positive lymph nodes was over 5, follow-up with no further surgery can be an option.

ABSTRACT
Background/Objectives@#Pediatric & Adolescent thyroid cancer is a steadily increasing malignancy. We aimed to report our experience at a single tertiary institution and to evaluate the risk factors for recurrence in pediatric & adolescent patients with differentiated thyroid carcinoma (DTC).Materials & Methods: The data of 42 pediatric & adolescent patients (aged ≤19 years) with DTC who underwent thyroidectomy at Seoul St. Mary’s Hospital (Seoul, Korea) between December 1997 and February 2019 were retrospectively reviewed. Clinicopathologic features and surgical outcomes were retrospectively analyzed through complete chart reviews. @*Results@#The mean age was 16.6 years. A total of 6 (14.3%) patients experienced recurrence after initial treatment. The recurrence rate was significantly different between total thyroidectomy (TT) and lobectomy groups (23.1% vs. 0%, p=0.038). However, no statistically significant differences were found in the recurrence rate according to lymph node ratio (LNR) of 0.4 (10.7% vs 21.4%; p=0.383). Multivariate analysis confirmed age (hazard ratio [HR], 0.443; p=0.008) and bilaterality (HR, 11.477; p=0.022) as significant risk factors for DFS. @*Conclusion@#Pediatric & Adolescent thyroid cancer is a rare malignancy and TT is recommended as the treatment of choice. However, lobectomy may be considered for Pediatric & Adolescent patients with age >16 years, tumor size <1 cm, and no bilateral disease.

ABSTRACT
Background@#The presence of telomerase reverse transcriptase (TERT) promoter mutations have been associated with a poor prognosis in patients with papillary thyroid carcinomas (PTC). The frequency of TERT promoter mutations varies widely depending on the population and the nature of the study. @*Methods@#Data were prospectively collected in 724 consecutive patients who underwent thyroidectomy for PTC from 2018 to 2019. Molecular testing for BRAF V600E and TERT promoter mutations was performed in all cases. @*Results@#TERT promoter alterations in two hotspots (C228T and C250T) and C216T were found in 16 (2.2%) and 4 (0.6%) of all PTCs, respectively. The hotspot mutations were significantly associated with older age at diagnosis, larger tumor size, extrathyroidal extension, higher pathologic T category, lateral lymph node metastasis, and higher American Thyroid Association recurrence risk. The patients with C216T variant were younger and had a lower American Thyroid Association recurrence risk than those with hotspot mutations. Concurrent BRAF V600E was found in 19 of 20 cases with TERT promoter mutations. Of 518 microcarcinomas measuring ≤1.0 cm in size, hotspot mutations and C216T variants were detected in five (1.0%) and three (0.6%) cases, respectively. @*Conclusions@#Our study indicates a low frequency of TERT promoter mutations in Korean patients with PTC and supports previous findings that TERT promoter mutations are more common in older patients with unfavorable clinicopathologic features and BRAF V600E. TERT promoter mutations in patients with microcarcinoma are uncommon and may have a limited role in risk stratification. The C216T variant seems to have no clinicopathologic effect on PTC.
ABSTRACT
BACKGROUND AND OBJECTIVES: The impacts of prophylactic central compartment neck dissection (pCCND) on the prognosis of papillary thyroid cancer (PTC) are controversial. The aim of this study is to evaluate the relationship between nodal factors of pCCND and the prognosis of PTC patients. MATERIALS AND METHODS: A total of 1754 patients who underwent thyroidectomy with pCCND were retrospectively reviewed. Nodal factor was defined as the number of metastatic lymph node (MLN), lymph node yield (LNY) and lymph node ratio (LNR). In regarding the cutoff of nodal factors, patients were categorized as low/high MLN, LNR and LNY group. The correlation of clinicopathologic characteristics including nodal factors and recurrence free survival (RFS) were anlalyzed. RESULTS: Of these, 1195 patients underwent thyroidectomy with unilateral pCCND and 559 patients underwent total thyroidectomy with bilateral pCCND. During follow-up, 45 (2.57%) patients showed recurrent disease. Of these, 19 patients underwent bilateral pCCND and 26 cases were unilateral pCCND. Gross extrathyroidal extension (ETE), high MLN and LNR showed statistically significant on RFS in univariate analysis in unilateral pCCND. In multivariate analysis, gross ETE and high LNR were independent risk factor of recurrence in unilateral pCCND. In bilateral pCCND, larger tumor size, minimal ETE, high MLN and LNR were significant correlation with RFS in univariate analysis. However, in multivariate analysis, multiple larger tumor and high LNR showed significant correlation with RFS. LNY was not statistically significant in both unilateral and bilateral pCCND. CONCLUSION: In regarding nodal factors, high LNR was only independent risk factor to worse RFS in both unilateral and bilateral pCCND in cN0 PTC patients.

BACKGROUND: Although Escherichia coli is a common cause of bacterial enteritis in Korea, reports on community-acquired E. coli enteritis in Korean children are scarce. This study aimed to determine the clinical characteristics and pathotype distribution of community-acquired E. coli enteritis diagnosed by a multiplex polymerase chain reaction (PCR) assay in Korean children. MATERIALS AND METHODS: The medical records of children aged 18 years or less who were diagnosed with acute gastroenteritis by the attending physician between 2013 and 2016 were retrospectively reviewed. The clinical characteristics of children diagnosed with E. coli enteritis were investigated and compared with those diagnosed with Salmonella enteritis. E. coli and Salmonella infections were diagnosed by a stool PCR assay. RESULTS: Among 279 children, in whom PCR assays for E. coli and Salmonella spp. were performed, Salmonella enteritis and E. coli enteritis were diagnosed in 43 (15.4%) and 39 (14.0%) children, respectively. Among the 39 children with E. coli enteritis, enteropathogenic E. coli (n=21, 53.8%) and enteroaggregative E. coli (n=15, 38.4%) were the most common causative agents. Empirical antibiotics were administered to 33 (84.6%) children. A total of 31 (79.5%) children developed fever, and 25 (80.6%) of them had the fever for 3 days or less, which resolved a median of 1 day (range 0-3 days) after hospitalization. The most frequent gastrointestinal symptom was diarrhea (n=36, 92.3%). Significantly more children with E. coli enteritis were aged 2 years or less as compared with those with Salmonella enteritis (41.0% vs. 21.9%, P = 0.021). Children with Salmonella enteritis more frequently complained of fever (97.7% vs. 79.5%, P = 0.012), abdominal pain (90.7% vs. 64.1%, P = 0.004), and hematochezia (46.5% vs. 10.3%, P < 0.001) than those with E. coli enteritis. Erythrocyte sedimentation rate and C-reactive protein levels were significantly higher in children with Salmonella enteritis than those with E. coli enteritis (P < 0.001). CONCLUSION: Enteropathogenic E. coli was the most frequent pathotype in Korean children with E. coli enteritis that caused mild clinical symptoms. A stool PCR assay for E. coli may be useful for epidemiological purpose and for an early diagnosis of E. coli enteritis.

PURPOSE: This study aimed to have a deeper insight into the clinical spectrum of foreign body aspiration in children and to prospect the further clinical implications of early diagnosis. METHODS: We conducted a retrospective medical chart review of 48 children with foreign bodies at The Catholic University of Korea, Seoul St. Mary's Hospital, between January 2009 and December 2013 in terms of age, sex, symptoms and signs, radiologic findings, and clinical courses. Patients were divided into 2 groups according to the time from aspiration to a definite diagnosis. The 2 groups were compared for clinical courses, radiologic findings, and the length of hospitalization. RESULTS: Approximately 85% of patients were 3 years of age or younger. About one-fifth of patients had no history of foreign body aspiration. Cough and coarse breathing sounds were the most common symptoms and signs. The most frequent radiologic finding was pulmonary air trapping (33.3%). The mostly commonly aspirated foreign body was peanut and detected in left main bronchus. Cough, sputum, and absence of aspiration history were more common in the delayed diagnosed group than in the early diagnosed group. CONCLUSION: Our results suggest that the number of accidents associated with foreign body aspiration can be reduced by keeping infants with nut formula under close observation and by conducting assertive bronchoscopic examination on children with delayed recovery from respiratory infections. After removal of foreign bodies, close monitoring and expectation of possible complications can prevent patients from a long hospital stay.

PURPOSE: In recent years, single-port laparoscopic appendectomy (SPLA) has been gaining in popularity and there have been many reports on the results of SPLA. The purpose of this study is to investigate feasibility, safety, and cosmetic satisfaction with SPLA in treatment of perforated appendicitis. METHODS: From September 2012 to March 2015, 227 patients underwent SPLA at Damsoyu hospital. The patients were divided into the simple and gangrenous appendicitis group (the S & G group) and the perforated appendicitis group (the P group). Operation time, hospital stay, drain insertion rate, surgical complication, and cosmetic satisfaction were evaluated. RESULTS: A total of 227 patients consisted of 32 patients in the P group and 195 patients in the S & G group. There were no significant differences in the demographic data of the patients. The operation time and hospital stay were significantly longer in the P group (p=0.002 and p<0.0001, respectively). The rate of drain insertion was also higher in the P group (p=0.0002). However, no differences in postoperative complications (p=0.281) and cosmetic satisfaction (p=0.090) were observed between the two groups. CONCLUSION: SPLA for perforated appendicitis is a feasible, safe, and cosmetically acceptable procedure. However, longer operation time and hospital stay and higher drain insertion rate should be considered for patients undergoing SPLA for perforated appendicitis.

PURPOSE: The early surgical outcomes of endoscopic thyroidectomy in papillary thyroid cancer (PTC) are comparable to those of conventional open thyroidectomy; however, there is little evidence about long-term outcomes. The aim of this study was to compare the 5-year surgical outcomes of endoscopic versus open thyroidectomy. METHODS: We reviewed 804 patients with PTC who underwent thyroidectomy between October 2008 and October 2010. Of these, 703 patients received conventional open thyroidectomy (OT group) and 101patients underwent endoscopic thyroidectomy (ET group). The clinicopathologic characteristics and surgical outcomes were compared between those treatments. RESULTS: ET was applied significantly more often in young patients and females. The lobectomy and unilateral CCND were performed more frequently in ET, and the mean tumor size was smaller. The prevalence of extrathyroidal extension, multiplicity, and lymphatic invasion was more frequent in OT. The T and TNM stage were more advanced in OT, whereas the N status was similar between treatments. The mean surgical time was significantly longer for ET, while the number of retrieved lymph nodes was greater in OT. However, the stimulated thyroglobulin levels at first RAI ablation, total amount of RAI administration and 5-year recurrence rate did not significantly differ between groups. The incidence of transient hypocalcemia was significantly higher in OT, but the incidence of permanent hypocalcemia and transient/permanent recurrent laryngeal nerve injury were similar in both groups. CONCLUSION: Endoscopic thyroidectomy might be a safe and effective procedure in well-selected PTC patients

PURPOSE: Recent studies have shown that interferon-gamma-inducible protein of 10 kDa (IP-10/CXCL10) levels is increased in acute bronchiolitis and asthma. The aim of this study was to examine the levels of IP-10 in children with wheezing and whether it correlates with other clinical variables. METHODS: A total of 62 subjects children were hospitalized for lower respiratory tract infection with wheezing and visited the Emergency Department due to an acute exacerbation of asthma. IP-10 levels were measured using enzyme-linked immunosorbent assay in the serum collected at admission. Serum IP-10 levels were evaluated for the relationships with age, sex, blood eosinophils counts, acute phase reactant, allergic sensitization, history of wheezing, and chest X-ray findings. RESULTS: Age showed a significant negative correlation with serum IP-10 levels (P=0.002). The serum levels of IP-10 were also significantly increased in patients with pneumonic infiltration on X-rays compared to those with normal or hyperinflation (P<0.009). There was no significant difference in the serum IP-10 level according to the other factors, including allergic sensitization. CONCLUSION: Serum IP-10 is significantly associated with inflammation of the lung and age, but not with allergic inflammation.

The purpose of this study is to enable children and adolescents to experience anatomy and clinics. For the purpose, the ways to use the anatomy educational resources (comics, 3-dimensional images, and 2-dimensional images) and diagnostic tools (stethoscope, sphygmomanometer, pen light, and reflex hammer) were described in a guide book. Following the guide book, students experienced anatomy and clinics in a course of the science museum. They learned anatomy with the comics, then did virtual dissection with the 3-dimensional and 2-dimensional images. Sequentially, with the diagnostic tools, they listened to heart sound, measured blood pressure, and performed light reflex and knee jerk. Through this study, we have found that anatomy and clinics should be experienced pleasantly. The complimentary guide book is expected to be further improved in future, so as to achieve better experience at home, science museum, and school.

OBJECTIVE: Ankylosing spondylitis is an inflammatory rheumatic disease mainly affecting the axial skeleton. The rigid spine may secondarily develop osteoporosis, further increasing the risk of spinal fracture. In this study, we reviewed fractures in patients with ankylosing spondylitis that had been clinically diagnosed to better define the mechanism of injury, associated neurological deficit, predisposing factors, and management strategies. METHODS: Between January 2003 and December 2013, 12 patients with 13 fractures with neurological complications were treated. Neuroimaging evaluation was obtained in all patients by using plain radiography, CT scan, and MR imaging. The ASIA Impairment Scale was used in order to evaluate the neurologic status of the patients. Management was based on the presence or absence of spinal instability. RESULTS: A total of 9 cervical and 4 thoracolumbar fractures were identified in a review of patients in whom ankylosing spondylitis had been diagnosed. Of these, 7 fractures were associated with a hyperextension mechanism. 10 cases resulted in a fracture by minor trauma. Posttraumatic neurological deficits were demonstrated in 11 cases and neurological improvement after surgery was observed in 5 of these cases. CONCLUSIONS: Patients with ankylosing spondylitis are highly susceptible to spinal fracture and spinal cord injury even after only mild trauma. Initial CT or MR imaging of the whole spine is recommended even if the patient's symptoms are mild. The patient should also have early surgical stabilization to correct spinal deformity and avoid worsening of the patient's neurological status.
