RESUMEN
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.”
RESUMEN
Purpose@#Current faculty development (FD) programs are mostly limited to medical education and often lack a comprehensive and systematic structure. Therefore, the present study aimed to explore the current status and needs of FD programs in medical schools to provide a basis for establishing FD strategies. @*Methods@#We conducted an online survey of medical school FD staff and professors regarding FD. Frequency, regression, and qualitative content analyses were conducted. FD programs were categorized into the classification frameworks. @*Results@#A total of 17 FD staff and 256 professors at 37 medical schools participated. There are gaps between the internal and external FD programs offered by medical schools and their needs, and there are gaps between the programs the professors participated in and their needs. Recent internal and external FD programs in medical schools have focused on educational methods, student assessment, and education in general. Medical schools have a high need for leadership and self-development, and student assessment. Furthermore, professors have a high need for leadership and self-development, and research. The number of participants, topics, and needs of FD programs varied depending on the characteristics of individual professors. @*Conclusion@#Medical schools should expand their FD programs to meet the needs of individuals and the changing demands of modern medical education. The focus should be on comprehensive and responsive programs that cover various topics, levels, and methods. Tailored programs that consider professors’ professional roles, career stages, and personal interests are essential for effective FD.
RESUMEN
Purpose@#This study aims to examine whether perceived levels of job stress, burnout, and mental health are different according to demographic characteristics and working conditions and to investigate the direct and indirect effects of job stress and burnout on the mental health of medical faculty members. @*Methods@#The study sample consists of 855 faculty members in 40 medical schools nationwide in the 2020 Burnout of Faculty Members of Medical Schools in Korea data with a grant from the Korean Association of Medical Colleges. This study employed structural equation modeling to construct causality among latent variables in addition to t-test, analysis of variance, and correlation coefficients for bivariate analyses. @*Results@#Perceived job stress, burnout, and mental health levels of medical faculty members showed significant group differences by demographic characteristics and working conditions. Job stress directly affected mental health (β=0.215, p<0.01) and indirectly affected mental health via burnout (β=0.493, p<0.001). Thus burnout significantly mediated the relationship between job stress and the mental health of medical faculty members. @*Conclusion@#This study found that job stress has direct and indirect effects on the mental health of medical faculty members, and burnout partially mediated this relationship. Further studies need to intervene in job stress and burnout to prevent the adverse mental health of medical faculty members and to introduce proper measures to improve working conditions affecting job stress and burnout.
RESUMEN
Purpose@#The starting time for probiotic supplementation in preterm infants after birth varies widely. This study aimed to investigate the optimal time for initiating probiotics to reduce adverse outcomes in preterm or very low birth weight (VLBW) infants. @*Methods@#Medical records of preterm infants born at a gestational age (GA) of <32 weeks or VLBW infants in 2011–2020 were reviewed respectively. The infants who received Saccharomyces boulardii probiotics within 7 days of birth were grouped into an early introduction (EI) group, and those who received supplemented probiotics after 7 days of birth were part of the late introduction (LI) group. Clinical characteristics were compared between the two groups and analyzed statistically. @*Results@#A total of 370 infants were included. The mean GA (29.1 weeks vs. 31.2 weeks, p<0.001) and birth weight (1,235.9 g vs. 1491.4 g, p<0.001) were lower in the LI group (n=223) than in the EI group. The multivariate analysis indicated that factors affecting the LI of probiotics were GA at birth (odds ratio [OR], 1.52; p<0.001) and the enteral nutrition start day (OR, 1.47; p<0.001). The late probiotic introduction was associated with a risk of late-onset sepsis (OR, 2.85; p=0.020), delayed full enteral nutrition (OR, 5.44; p<0.001), and extrauterine growth restriction (OR, 1.67; p=0.033) on multivariate analyses after adjusting for GA. @*Conclusion@#Early supplementation of probiotics within a week after birth may reduce adverse outcomes among preterm or VLBW infants.
RESUMEN
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.
RESUMEN
Background@#There is no national survey on medical school faculty members’ burnout in Korea. This study aimed to investigate burnout levels and explore possible factors related to burnout among faculty members of Korean medical schools. @*Methods@#An anonymous online questionnaire was distributed to 40 Korean medical schools from October 2020 to December 2020. Burnout was measured by a modified and revalidated version of the Maslach Burnout Inventory-Human Service Survey. @*Results@#A total of 996 faculty members participated in the survey. Of them, 855 answered the burnout questions, and 829 completed all the questions in the questionnaire. A significant number of faculty members showed a high level of burnout in each sub-dimension: 34% in emotional exhaustion, 66.3% in depersonalization, and 92.4% in reduced personal accomplishment. A total of 31.5% of faculty members revealed a high level of burnout in two sub-dimensions, while 30.5% revealed a high level of burnout in all three sub-dimensions.Woman faculty members or those younger than 40 reported significantly higher emotional exhaustion and depersonalization. Long working hours (≥ 80 hours/week) showed the highest reduced personal accomplishment scores (F = 4.023, P = 0.018). The most significant stressor or burnout source was “excessive regulation by the government or university.” The research was the most exasperating task, but the education was the least stressful. @*Conclusion@#This first nationwide study alerts that a significant number of faculty members in Korean medical schools seem to suffer from a high level of burnout. Further studies are necessary for identifying the burnout rate, related factors, and strategies to overcome physician burnout.
RESUMEN
Purpose@#Croup is a clinical manifestation of coronavirus disease 2019 (COVID-19) in children. The Omicron variant of severe acute respiratory syndrome coronavirus 2 usually causes an upper respiratory tract infection. We investigated the differences between croups caused by COVID-19 and by other respiratory viruses (ORV). @*Methods@#We reviewed clinical characteristics, therapeutic measures, and the Westley Croup Score of children with croup who visited the emergency department of Gyeongsang National University Hospital from January 1 through April 7, 2022. According to the laboratory-confirmed viruses, they were divided into 2 groups: COVID-19 and ORV. Between the 2 groups, we compared the abovementioned features. Moderate-to-severe croup was defined by a Westley Croup Score of 3 or higher. @*Results@#A total of 20 children were diagnosed with croup caused by COVID-19 (n = 11; median age, 18 months) or by ORV (n = 9; 7 months). Median Westley Croup Score was higher in the COVID-19 group than in the ORV group (5.0 [range, 0-10.0] vs. 2.0 [1.0-5.0]; P = 0.031). Among the components of the scoring system, only stridor showed a significant difference (e.g., “stridor at rest”: COVID-19, 8 of 11 vs. ORV, 2 of 9; P = 0.046). Median C-reactive protein concentration was higher in the COVID-19 group (3.2 vs. 0.4 mg/L; P = 0.007). Severity of the COVID-19 group was marginally higher than that of the ORV group in terms of the median oxygen saturation (95% vs. 98%; P = 0.056) and the proportions of moderate-to-severe croup (9 of 11 vs. 3 of 9; P = 0.065) and application of high-flow nasal cannula (4 of 11 vs. 0 of 9; P = 0.094). @*Conclusion@#Croup caused by COVID-19 during the period of dominance of the Omicron variant outbreak might be more severe than croup caused by ORV.
RESUMEN
A small proportion of children with coronavirus disease 2019 (COVID-19) develop severe pneumonia. We reported the severe COVID-19 pneumonia in children aged <18 years with COVID-19 treated with remdesivir and dexamethasone from August 2021 to November 2021 by a retrospective review of their medical records. Eight children were included (5 males and 3 females). Their median age was 16 years (range: 9 to 17 years) and their median body mass index was 30.5 kg/m 2 (range: 22.8–38.5 kg/m 2 ). All patients had fever and dyspnea with hypoxia. Chest radiographic findings were variable and included diffuse or multifocal consolidation, nodules, and ground-glass opacities in the lungs. After receiving intravenous remdesivir and dexamethasone, 7 of the 8 children experienced an improvement in their symptoms within 2 days. In our case series, obesity was present in 6 out of 8 children with severe COVID-19 pneumonia.
RESUMEN
Background and Objectives@#Pilomatricoma is a frequently diagnosed skin lesion of the head and neck that may often be misdiagnosed as other skin lesions. This study evaluated whether ultrasonography (USG) or computed tomography (CT) is the most helpful imaging modality for the accurate preoperative diagnosis of pilomatricoma in head and neck regions of children and adolescents.Subjects and Method A retrospective review was conducted for 59 patients with pilomatricoma under the age of 19 years. All cases were pathologically confirmed with pilomatricoma in the head or neck. @*Results@#Preoperative imaging examinations were performed with USG in six cases and with CT in nine cases. The accuracy of preoperative diagnosis was compared between three groups: 1) with clinical findings only, 2) with USG, and 3) with CT. The correct preoperative diagnosis was made in 18 (30.5%) of the total of 59 cases. Using only clinical findings, 10 (22.7%) out of 44 patients were diagnosed as pilomatricoma. With the addition of USG, pilomatricoma was diagnosed in 1 (16.7%) out of six cases, whereas with the addition of CT, 7 (77.8%) out of 9 cases (77.8%) were diagnosed correctly. Preoperative diagnosis of pilomatricoma with CT imaging was more accurate than clinical findings only (vs. CT; odds ratio [OR]=11.900, 95% confidence interval [CI] 2.126-66.615; p=0.001) or USG (vs. CT; OR=17.500, 95% CI 1.223-250.357; p=0.020). @*Conclusion@#In the preoperative diagnosis of pilomatricoma, imaging modalities such as CT and USG are helpful, with CT offering higher diagnostic accuracy and USG procedural benefits in younger children.
RESUMEN
Web in common bile duct (CBD web) is very rare. It is usually asymptomatic and detected incidentally during surgery for other causes in adults. It can be congenital or acquired, however congenital CBD web is extremely rare. Currently, despite its invasiveness and complications, endoscopic retrograde cholangiopancreatography (ERCP) is considered as a useful diagnostic and therapeutic modality in children with hepatobiliary pancreatic diseases as in adults. Herein we report a case of congenital CBD web presenting with acute pancreatitis and choledocholithiasis in a 4-year-old girl which was diagnosed and treated using balloon dilation under ERCP. After balloon dilation of the web, a common pancreatobiliary channel was observed. To the best of our knowledge, a case of congenital CBD web with pancreatobiliary junctional abnormality treated using ERCP in a child has not been reported to date.
RESUMEN
BACKGROUND/OBJECTIVES@#To evaluate the nutritional status and prevalence of malnutrition in hospitalized children at admission and during hospitalization in South Korea. @*SUBJECTS/METHODS@#This first cross-sectional nationwide “Pediatric Nutrition Day (pNday)” survey was conducted among 872 hospitalized children (504 boys, 368 girls; 686 medical, 186 surgical) from 23 hospitals in South Korea. Malnutrition risk was screened using the Pediatric Yorkhill Malnutrition Score (PYMS) and the Screening Tool Risk on Nutritional status and Growth. Nutritional status was assessed by z-scores of weight-for-age for underweight, weight-for-height for wasting, and height-for-age for stunting as well as laboratory tests. @*RESULTS@#At admission, of the 872 hospitalized children, 17.2% were underweight, and the prevalence of wasting and stunting was 20.2% and 17.3%, respectively. During hospitalization till pNday, 10.8% and 19.6% experienced weight loss and decreased oral intake, respectively.During the aforementioned period, fasting was more prevalent in surgical patients (7.5%) than in medical patients (1.6%) (P < 0.001). According to the PYMS, 34.3% and 30% of the children at admission and on pNday, respectively, had a high-risk of malnutrition, requiring consultation with the nutritional support team (NST). However, only 4% were actually referred to the NST during hospitalization. @*CONCLUSIONS@#Malnutrition was prevalent at admission and during hospitalization in pediatric patients, with many children experiencing weight loss and poor oral intake. To improve the nutritional status of hospitalized children, it is important to screen and identify all children at risk of malnutrition and refer malnourished patients to the multidisciplinary NST for proper nutritional interventions.
RESUMEN
Treatments aimed at eradicating Helicobacter pylori (H. pylori) infections in children and adolescents should be clearly beneficial. According to the updated guidelines, a 14-day triple therapy or bismuth-based triple therapy is the first choice for treatment of children based on the results of antimicrobial sensitivity testing. Though culturing H. pylori using biopsy specimens is not always feasible, it should be performed for establishing empirical rescue therapy for patients not responding to first-line eradication therapy. The European and North American therapeutic strategies for children and adolescents with H. pylori infections may not be appropriate for treating children and adolescents in other countries owing to regional differences in epidemiological characteristics of H. pylori. The existence of clarithromycin-resistant H. pylori is an important factor involved in eradication failure. The development of new treatment-related allergies, treatment failure, side effects, and alteration of the gut microbiome have been highlighted as factors potentially outweighing the possible benefit of preventing future peptic ulcers or gastric cancer. Drug compliance can be improved by providing a detailed explanation of the reason for therapy, duration, and routes of drug administration. Physicians should understand the mechanisms underlying eradication treatment and explain drug prescriptions in detail to both parents and children to increase compliance. Herein, we reviewed the indications for and various modalities of eradication treatment in children with H. pylori infections in accordance with a review of recently published articles.

RESUMEN
Purpose@#Recurrence patterns in rectal cancer patients treated with preoperative chemoradiotherapy (PCRT) are needed to evaluate for establishing tailored surveillance protocol. @*Methods@#This study included 2,215 patients with locally-advanced mid and low rectal cancer treated with radical resection between January 2005 and December 2012. Recurrence was evaluated according to receipt of PCRT; PCRT group (n = 1,258) and no-PCRT group (n = 957). Early recurrence occurred within 1 year of surgery and late recurrence after 3 years. The median follow-up duration was 65.7 ± 29 months. @*Results@#The overall recurrence rate was similar between the PCRT and no-PCRT group (25.8% vs. 24.9%, P = 0.622). The most common initial recurrence site was the lungs in both groups (50.6% vs. 49.6%, P = 0.864), followed by the liver, which was more common in the no-PCRT group (22.5% vs. 33.6%, P = 0.004). Most of the recurrence occurred within 3 years after surgery in both groups (85.3% vs. 85.8%, P = 0.862). Early recurrence was more common in the PCRT group than in the no-PCRT group (43.1% vs. 32.4%, P = 0.020). Recurrence within the first 6 months after surgery was significantly higher in the PCRT group than in the no-PCRT group (18.8% vs. 7.6%, P = 0.003). Lung (n = 27, 44.3%) and liver (n = 22, 36.1%) were the frequent the first relapsed site within 6 months after surgery in PCRT group. @*Conclusion@#Early recurrence within the first 1 year after surgery was more common in patients treated with PCRT. This difference would be considered for surveillance protocols and need to be evaluated in further studies.
RESUMEN
This study assessed the clinical performance of 150 third-year medicalstudents in Busan, Korea in a whole-task emergency objective structured clinical examination station that simulated a patient with palpitations visiting the emergency department. The examination was conducted from November 25 to 27, 2019. Clinical performance was assessed as the number and percentage of students who performed history-taking (HT), a physical examination (PE), an electrocardiography (ECG) study, patient education (Ed), and clinical reasoning (CR), which were items on the checklist. It was found that 18.0% of students checked the patient’s pulse, 51.3% completed an ECG study, and 57.9% explained the results to the patient. A sizable proportion (38.0%) of students did not even attempt an ECG study. In a whole-task emergency station, students showed good performance on HT and CR, but unsatisfactory results for PE, ECG study, and Ed. Clinical skills educational programs for subjected student should focus more on PE, timely diagnostic tests, and sufficient Ed.
RESUMEN
Nephrogenic diabetes insipidus (DI) is a rare disease in which the patient cannot concentrate urine despite appropriate or high secretion of antidiuretic hormone. Congenital nephrogenic DI is caused by the arginine vasopressin receptor 2 (AVPR2) or aquaporin 2 (AQP2) gene mutation; the AVPR2 genetic mutation accounts for 90% of the cases. National health screening for infants and children was launched in 2007 in order to prevent accidents and promote public health in infants and children in Korea. The program has been widely used as a primary clinical service in Korea. We treated an infant with faltering growth and delayed development detected by the National health screening program, and diagnosed the problem as nephrogenic DI caused by a rare missense mutation of c.490T>C on the AVPR2 gene. This case can be a good educational nephrogenic DI with a rare AVPR2 mutation, which was well screened and traced by the national health screening program for infants and children in Korea.
RESUMEN
Background@#The objective of this study was to examine changes in the prevalence of cytotoxic-associated gene A (CagA) positive Helicobacter pylori infection in Jinju, Korea, over the last 20 years. @*Methods@#Three cross-sectional analyses were conducted concurrently. A total of 1,305 serum samples were collected from 1994–1995, 2004–2005, and 2014–2015, respectively. The presence of immunoglobulin (Ig) G, IgA, and IgM antibodies against H. pylori CagA protein was examined by western blotting. @*Results@#Overall, seropositivity for anti-CagA IgG antibody was significantly decreased from 63.2% to 42.5% over the last 20 years (P < 0.001). Anti-CagA IgG seropositivities in children and young adults aged 10–29 years decreased from 1994 (60.0%–85.0%) to 2015 (12.5%– 28.9%). The age when plateau of increasing IgG seropositivity was reached in each study period shifted from the 15–19 year-old group in 1994–1995 (85.0%) to the 40–49 year-old group in 2014–2015 (82.5%). Overall seropositive rates of anti-CagA IgA and IgM antibodies did not change significantly either over the last 20 years. @*Conclusion@#H. pylori infection rate in children and young adults declined over 20 years in Jinju, probably due to improved sanitation, housing, or economy.
RESUMEN
Oral rehydration solution (ORS) is safe and effective for the prevention and treatment of dehydration in children. It has been commercially available as a small packaging unit that needs to be taken with a specified amount of water. Intake of incorrectly formulated ORS results in side effects, such as electrolyte imbalance and upper gastrointestinal (GI) disturbance. We experienced a case of severe GI hemorrhage from gastric and duodenal ulcers in a previously healthy child following intake of incorrectly formulated ORS. GI hemorrhage in children is often life threatening and reaching a diagnosis may be challenging. Commercially manufactured packets of powdered oral rehydration salts have been widely used and GI hemorrhage associated with an improperly diluted ORS has been rarely reported. Caution and education for proper preparation of ORS are imperative.
