ABSTRACT
Background/Aims@#The recent update on the Selecting Therapeutic Targets in Inflammatory Bowel Disease initiative has added normal growth in children as an intermediate target in Crohn’s disease and ulcerative colitis. We aimed to investigate factors associated with reaching midparental height (MPH) in patients diagnosed with inflammatory bowel disease in childhood and the adolescent period. @*Methods@#This multicenter retrospective observational study included pediatric patients with inflammatory bowel disease that had reached adult height. Factors associated with reaching MPH were investigated by logistic regression analyses. @*Results@#A total of 166 patients were included in this study (128 Crohn’s disease and 38 ulcerative colitis). Among them, 54.2% (90/166) had reached their MPH. Multivariable logistic regression analysis revealed that height Z-score at diagnosis and MPH Z-score were independently associated with reaching MPH (odds ratio [OR], 8.45; 95% confidence interval [CI], 4.44 to 17.90;p<0.001 and OR, 0.11; 95% CI, 0.04 to 0.24; p<0.001, respectively). According to the receiver operating characteristic curve analysis, the optimal cutoff level of "height Z-score at diagnosis minus MPH Z-score" that was associated with reaching MPH was –0.01 with an area under the curve of 0.889 (95% CI [0.835 to 0.944], sensitivity 88.9%, specificity 84.2%, positive predictive value 87.0%, negative predictive value 86.5%, p<0.001). @*Conclusions@#Height Z-score at diagnosis and MPH Z-score were the only factors associated with reaching MPH. Efforts should be made to restore growth in pediatric patients who present with a negative “height Z-score at diagnosis minus MPH Z-score.”
ABSTRACT
Preservation of the recurrent laryngeal nerve (RLN) is a priority for surgeons during thyroidectomy in patients with papillary thyroid cancer (PTC). RLN invasion by PTC in a patient presenting with preoperative vocal fold paralysis may require resection of the nerve with the tumor. However, the decision should be made regarding whether to preserve or sacrifice a functioning RLN invaded by PTC. Under certain conditions, preservation of the nerve with incomplete tumor resection could be considered. An RLN that has been resected due to PTC invasion may be managed by various reinnervation techniques to improve vocal outcomes. This article reviews clinical considerations and rationales for surgical decisions related to patients with PTC invasion of the RLN.
ABSTRACT
Objectives@#This study aimed to examine the association between overtime hours and perceived stress, depression, and anxiety among coronavirus disease 2019 (COVID-19) community health workers. @*Methods@#Self-report data were collected from 1,181 community health workers in Busan between 15 June and 2 July 2021. The data collected were analyzed using analysis of variance and logistic regression to examine how average weekly overtime hours affect perceived stress, depression, and anxiety. @*Results@#The proportion of individuals who perceived a high degree of stress was higher in the groups with average weekly overtime of 5-10 hours (odds ratio [OR] 1.81, 95% confidence interval [CI] 1.09-3.01) and 10 or more hours (OR 2.26, 95% CI 1.33-3.82) than in the group with average weekly overtime of less than 5 hours. Among the groups with average weekly overtime of 5-10 hours and 10 or more hours, the proportion of individuals at a high risk of depression was OR 1.74 (95% CI 1.31-2.31) and OR 3.39 (95% CI 2.53-4.54), respectively. In the same two groups, the proportion of individuals at a high risk of anxiety was OR 1.75 (95% CI 1.31-2.33) and OR 3.34 (95% CI 2.51-4.46), respectively. @*Conclusions@#This study shows that perceived stress, depression, and anxiety levels significantly increase as average weekly overtime hours increase among COVID-19 community health workers.
ABSTRACT
Since COVID-19 pandemic, extreme care must be taken to not only tracheotomy, but also subsequent tube management so that medical staff and other patients can be protected from infectious aerosols from the patient. Numerous studies have been reported worldwide on the timing and indications for tracheotomy in COVID-19 patients since 2019. In this paper, we describe the issues to be considered not only during tracheostomy but also before and after procedure in COVID-19 patients with the literatures review.
ABSTRACT
Infants who are born between 24 hours and 1 year of age require extreme caution in their care due to their fragility. However, if there are multiple risk factors associated with the infant, caretaker, household, and surrounding circumstances, providing proper and appropriate care becomes problematic. This difficulty in caring for infants can contribute to abuse, neglect, or even death. This study investigates unexplained infant deaths that occur in the presence of multiple psychosocial risk factors. This study aimed to explore the relationship between various psychosocial risk factors and sudden, unexplained infant deaths. We examined nine cases from the autopsy archive of the National Forensic Service using a statistical approach. Among these cases, three were subject to legal action, while six were closed without further legal process. Although it was difficult to establish a clear relationship between death and abuse or neglect in the six cases, all were found to have experienced a harsh environment that was similar to abuse or neglect. We discuss the implications of our findings for understanding infant deaths and legal outcomes and propose a new framework to understand the deaths of infants.
ABSTRACT
Background@#Swallowing of foreign bodies (FBs) is the most common indication of therapeutic endoscopy in children. Endoscopic removal may be necessary depending on the type of FB, age of the child, and location of the FB. We attempted to analyze the characteristics of each device used for the endoscopic removal of FBs in children. @*Methods@#Medical records of the patient’s age, sex, weight, type, location, size, shape, type of device used for endoscopic removal, and endoscopic time were retrospectively collected. @*Results@#A total of 424 FB removal procedures were analyzed. The average age of the patients at the time of FB removal was 4.1 ± 3.7 years. Coins were the most common FBs (192, 45.3%). The most common locations of the FBs were the esophagus (45.7%) and the stomach (48.3%), respectively. For a total of 371 cases, forceps were used in 96 cases (25.9%) for esophageal FBs and in 25 cases for gastric FBs (6.7%), while nets were used in 250 cases (67.4%) for gastric FBs retrieval; the average durations of the procedures were 7.2 ± 7.4 minutes, 8.5 ± 7.2 minutes, and 5.7 ± 7.3 minutes, respectively (P = 0.003). The procedure time was significantly shorter, in the group of patients with low body weights, when nets were used than when forceps were used to remove gastric FBs (P = 0.001). @*Conclusion@#The endoscopic procedure duration, in low-weight children, was shorter when retrieval nets were used than that with forceps.
ABSTRACT

Figures can be used to display characteristics and distributions of data, allowing for intuitive understanding through visualization and thus making it easier to interpret the statistical results. To maximize the positive aspects of figure presentation and increase the accuracy of the content, in this article, the authors will describe how to choose an appropriate figure type and the necessary components to include. Additionally, this article includes examples of figures that are commonly used in research and their essential components using virtual data.
ABSTRACT
Purpose@#This study evaluated the predictive role of fecal calprotectin (FC) measured at an early stage of treatment for monitoring clinical remission (CR) after six months and endoscopic remission (ER) after one year of treatment in pediatric Crohn’s disease (CD). @*Methods@#This retrospective study included 45 patients who simultaneously underwent ileocolonoscopy and FC testing during follow-up. FC levels were measured before and after six weeks of treatment. CR was assessed after six months of treatment using Pediatric Crohn’ s Disease Activity Index and acute-phase reactants. ER was assessed after one year using the Simple Endoscopic Score for Crohn’s Disease. @*Results@#Twenty-nine (64.4%) patients used oral prednisolone for remission induction and 16 (35.6%) patients used anti-tumor necrosis factor-alpha. Thirty (66.7%) patients achieved CR, while 24 (53.3%) achieved ER. The FC level measured after six weeks of treatment could predict CR (χ2 =9.15, p=0.0025) and ER (χ2 =12.31, p=0.0004). The δFC could predict CR (χ2 =7.91, p=0.0049), but not ER (χ2 =1.85, p=0.1738). With a threshold of ≤950.4 µg/g, FC at week six could predict CR with 76.7% sensitivity and 73.3% specificity. The area under the curve (AUC) was 0.769 (standard error 0.0773, p=0.0005). The same threshold predicted ER with 87.5% sensitivity and 71.4% specificity. The AUC was 0.774 (standard error 0.074, p=0.0002). @*Conclusion@#FC assay at an early stage of treatment can be used as a surrogate marker to predict CR and mucosal healing in pediatric CD.
ABSTRACT
Lymph node metastasis is the single, most powerful prognostic factor in head and neck squamous cell cancer, which means that cervical lymph node management should be considered even in treatment of a clinically node-negative neck. More conservative and selective techniques of neck dissection have been developed ever since radical neck dissection was first introduced. Despite that selective neck dissection provides less functional damage, disfiguring scar after neck dissection still remains inevitable. Recently, surgical endoscopy and robotic system was introduced and many clinical trials for aesthetic approach for neck dissection using endoscopy have shown their feasibility and safety. Hereby, we describe the preparation and surgical procedure for endoscopic selective neck dissection (level I, II, and III) via retroauricular approach for 41-year-old male patient with clinically node-negative oral tongue cancer.
ABSTRACT
General medical journals such as the Korean Journal of Anesthesiology (KJA) receive numerous manuscripts every year. However, reviewers have noticed that the tables presented in various manuscripts have great diversity in their appearance, resulting in difficulties in the review and publication process. It might be due to the lack of clear written instructions regarding reporting of statistical results for authors. Therefore, the present article aims to briefly outline reporting methods for several table types, which are commonly used to present statistical results. We hope this article will serve as a guideline for reviewers as well as for authors, who wish to submit a manuscript to the KJA.
ABSTRACT
Objective@#We investigated which factors in psychological changes positively or negatively affect the quality of life to suggest desirable directions in the period of the COVID-19 pandemic. @*Methods@#Online survey was conducted with 1,011 adults more than 19 years old in Busan, South Korea. Quality of life was measured using the World Health Organization Quality of Life-BREF. Questions regarding the psychological changes were about COVID-19-related concerns, distress in complying with quarantine guidelines, and interest in seeking something to do alone. @*Results@#Quality of life was perceived to be below average (mean±SD, 2.86±0.53). The more economic worries there were, the lower the quality of life in psychological, social relationships and environmental domains. The more distress one experienced when maintaining their personal hygiene, the higher the quality of life related to their physical health. Likewise, the more difficult it was to maintain social distances, the higher the quality of life associated with psychological and social relationships. The more interested someone was in how to spend time alone, the higher the quality of life in all domains significantly. @*Conclusion@#We can minimize the negative impacts of COVID-19 by maintaining economic stability, maintaining prosocial behaviors related to personal hygiene and making good use of personal time.

ABSTRACT
Objectives@#. To compare the surgical outcomes of externally monitored and conventional buried flaps with the goal of determining the usefulness of external monitoring of buried flaps. @*Methods@#. In this case-control study with propensity score matching, 30 patients were evenly divided into externally monitored buried flap and conventional buried flap groups. The total operative time for free flap reconstruction, the flap survival rate, the length of hospital stay, the initial time of a reliable visual assessment, complications, the final diet achieved, and the duration until diet initiation were compared between the groups. @*Results@#. The mean operative time for reconstruction was 115 minutes (interquartile range, 85–150 minutes) and 142 minutes (interquartile range, 95–180 minutes) in the externally monitored and conventional groups, respectively (P= 0.245). The median length of hospital stay was 24 days (interquartile range, 18–30 days) and 27 days (interquartile range, 20–41 days) in the externally monitored and conventional groups, respectively (P=0.298). The median duration until diet initiation was 15 days (interquartile range, 15–21 days) and 18 days (interquartile range, 15–34 days) in the externally monitored and conventional groups, respectively (P=0.466). The final diet, initial time of a reliable visual assessment, and complications were comparable between the groups, but the external skin paddle provided an excellent visual assessment immediately postoperatively in all cases. @*Conclusion@#. The outcomes were comparable between the groups, indicating that externalization of the cutaneous component of a buried flap may be a straightforward and useful technique for monitoring a buried anterolateral thigh free flap in laryngopharyngeal reconstructions. The salvage and false-positive rates of compromised flaps should be compared in large subject groups in future studies to prove that the use of an external skin paddle improves flap monitoring.
ABSTRACT
Thyroid and parathyroid surgery is commonly performed for diagnostic or therapeutic purposes for benign tumors as well as malignant tumors. Vocal cord paralysis and hypoparathyroidism are known as major complications. However, majority of patients experience neck pain or discomfort after surgery without any significant cause. Recent studies have reported various and ambiguous symptoms group after thyroidectomy as post-thyroid syndrome. There is still controversy over the etiology of post-thyroidectomy syndrome, however the assumable causes identified so far are damage to the laryngeal mucosa caused by tracheal intubation, disturbances of blood circulation of larynx, synechia of strap muscles, limited vertical motion of laryngeal skeleton, fibrosis during healing process of extrinsic laryngeal muscles. This is the systematic review of the post-thyroidectomy symptoms by cause.
ABSTRACT
Multicellular spheroids (MCSs) from three dimensional culture, which is a complex architectural structure with dynamic cell to cell and cell to matrix interactions, mimic real tissues regarding structural and functional properties. MCSs have emerged as an effective tool for filling up the gap between the in vitro and in vivo experimental model and can replace the in vivo model. The viability and functional performance can be enhanced when cells are grown as multicellular spheroid (MCS). In this review paper, we discussed the basic mechanism of MCS formation, their biomedical applications, and recent advances in MCS culture and tissue engineering.
ABSTRACT
Background@#Non-adherence to oral maintenance therapy in adolescents with inflammatory bowel disease (IBD) is a significant healthcare problem. Knowledge of the prescribed medication can increase medication adherence. We aimed to investigate the relationship between medication adherence and disease-related knowledge of pediatric and adolescent patients with IBD. @*Methods@#We conducted a “pop quiz” to investigate the disease-related knowledge of pediatric patients with IBD who were followed-up at our institution and reviewed their medical records, including data on sex, diagnosis, age at diagnosis, and disease duration. Medication adherence was evaluated by the doctor in charge, and ≥ 80% of patients constituted the “good adherence group.” @*Results@#Of 93 patients, 59 (63.4%) were males, and 78 (83.9%) had Crohn's disease. The mean age at diagnosis was 13.8 ± 2.8 years; mean follow-up duration, 4.8 ± 3.4 years; and mean patient age, 18.6 ± 3.7 years. Only 65 patients (69.9%) knew the exact name of the medication they were currently taking, and 34 (36.6%) knew the correct dose. Only 15 patients (16.1%) knew the name of the medications they were previously taking. A total of 64 patients (66.8%) showed an adherence rate of 80% for the weekly prescribed oral medication. The patients in the poor adherence group were significantly older than those in the good adherence group (P = 0.035). The number of hospitalizations per year was statistically higher in the good adherence group (P = 0.024). The proportion of patients who knew the names of the medications they were previously taking and were aware of the side effects of the medications was significantly higher in the good adherence group (P = 0.008 and P = 0.020, respectively). @*Conclusion@#Adolescent IBD patients have lower oral medication adherence. Knowledge of the prescribed medications taken previously, and the adverse effects of these medications are associated with good adherence. IBD specialists should educate the patients regarding the disease and about their medication.
ABSTRACT
Background@#Neuropathic pain (NP) is considered a clinically incurable condition despite various treatment options due to its diverse causes and complicated disease mechanisms. Since the early 2000s, multipotent human mesenchymal stem cells (hMSCs) have been used in the treatment of NP in animal models. However, the effects of hMSC injections have not been studied in chronic post-ischemia pain (CPIP) mice models. Here, we investigated whether intrathecal (IT) and intrapaw (IP) injections of hMSCs can reduce mechanical allodynia in CPIP model mice. @*Methods@#Seventeen CPIP C57/BL6 mice were selected and randomized into four groups: IT sham (n = 4), IT stem (n = 5), IP sham (n = 4), and IP stem (n = 4). Mice in the IT sham and IT stem groups received an injection of 5 μL saline and 2 × 104 hMSCs, respectively, while mice in the IP sham and IP stem groups received an injection of 5 μL saline and 2 × 10 5 hMSCs, respectively. Mechanical allodynia was assessed using von Frey filaments from pre-injection to 30 days post-injection. Glial fibrillary acidic protein (GFAP) expression in the spinal cord and dorsal root ganglia were also evaluated. @*Results@#IT and IP injections of hMSCs improved mechanical allodynia. GFAP expression was decreased on day 25 post-injection compared with the sham group. Injections of hMSCs improved allodynia and GFAP expression was decreased compared with the sham group. @*Conclusions@#These results suggested that hMSCs may be also another treatment modality in NP model by ischemia-reperfusion.
ABSTRACT
Objectives@#It remains unclear whether methylphenidate (MPH) has yadverse effects on growth in children. This study aimed to investigate the association of MPH with serum biological markers of growth in children with attention-deficit/hyperactivity disorder (ADHD). @*Methods@#The present study included 103 children with ADHD (64 drug-naive children, 39 MPH-treated children) and 112 control subjects. Children with ADHD were diagnosed on the basis of a semi-structured interview. Levels of biochemical markers of growth, including insulin-like growth factor-I, thyroid stimulating hormone (TSH), free T4, calcium, phosphorus, alkaline phosphatase, vitamin D, hemoglobin, total protein, albumin, total cholesterol, and hematocrit were measured in these individuals. @*Results@#Except in case of TSH, no intergroup differences were found in the levels of the growth markers. The levels of TSH were found to be lower in the MPH-treated boys with ADHD than in the drug-naive and control groups (p<0.05), although the levels of TSH in all the groups were within normal limits. @*Conclusion@#In this cross-sectional study, no significant association was found between MPH and growth markers. This calls for the need to carry out prospective longitudinal research studies in the future that investigate the effect of MPH on the growth trajectory in children.
ABSTRACT
Methods@#Total 179 normal, asymptomatic Korean men were divided in to three groups (6th, 7th, and 8th decade) according to their age. Standard sagittal spinopelvic parameters, including TK and thoracolumbar kyphosis, were measured and subdivided into the following four segments: A (C7 upper end plate [UEP]–T5 UEP), B (T5 UEP–T10 UEP), C (T10 UEP–T12 lower end plate [LEP]), and D (T12 LEP–L2 LEP). These segments of the three study groups were analyzed. @*Results@#In segment B, the segmental kyphosis of group 3 (20.2°±8.0°) showed a statistically larger value than that of group 1 (15.6°±6.8°) and group 2 (16.7°±8.8°) (p=0.017). In segment C, the segmental kyphosis of group 2 (12.9°±6.5°) and group 3 (12.2°±7.1°) showed statistically larger values than that of group 1 (9.5°±6.2°) (p=0.016). The A and D segments of the three groups were not significantly different. @*Conclusions@#Increased TK was observed in the middle (segment B) and lower (segment C) thoracic segments in normal asymptomatic male subjects with age. The results from the natural progression of segmental kyphosis with age would provide baseline reference data to help surgeons choose the optimal point of the upper instrumented vertebra level for preventing proximal junctional kyphosis.
