Objectives: ：The purpose of this study was to identify the change in the reasons for referrals before and after the COVID-19 outbreak among students who were referred to the one hospital-linked Wee center in Dalseo-gu, Daegu. Methods: ：324 students who were referred to one hospital-linked Wee center for personal counseling from January 1, 2019 to December 31 were included. In the initial session of individual counseling, 3 of the chief reasons among 27 emotional and/or behavioral problems were indicated. This reason was divided into before and after COVID-19 to determine whether there is a difference, and whether there is a difference between before and after COVID-19 depending on the school level. Results: ：The most frequent emotional and/or behavioral problem was ‘interpersonal problems’ in both pre- COVID-19 and post- COVID-19 groups. In post- COVID-19 group, ‘anxiety’ was significantly increased, whereas ‘conduct problems,’ ‘impulsivity’ and ‘inattention’ were significantly decreased. In elementary students group, only ‘conduct problems’ was significantly decreased after COVID-19 and the same result was shown in middle and high school students group. Conclusions ：The study showed that after COVID-19 pandemics in Daegu the difference of students’ problems was noted, and internalizing problems seem to increase rather than externalizing problems. This result calls upon schools to plan for students’ further mental health care measures.

Background: Few studies have investigated the association between Behçet disease (BD) and cardiovascular disease (CVD). The aim of this study was to investigate the risk of various CVDs in patients with BD. Objective: The aim of this study was to investigate the risk of various CVD in patients with BD. Methods: Between 2003 and 2015, we performed a retrospective cohort study involving patients with BD selected from Korea’s National Health Insurance Service-National Sample Cohort database and age- and sex-matched controls. Age- and sex-matched controls were selected randomly from the NHIS-NSC database at a frequency of 1:5. Results: Among the 998 patients with BD and the 4,990 controls studied, patients with BD showed significantly higher risk for angina pectoris (adjusted Hazard Ratio [HR] 1.522, 95% confidence interval [CI] 1.020∼2.273;p=0.04) and peripheral arterial disease (adjusted HR 2.939, 95% CI 1.296∼6.664; p=0.01) than the controls. The cumulative incidence rates of these diseases in patients with BD were also significantly higher than those in the controls. Conclusion Patients with BD showed independent risk for angina pectoris and peripheral arterial disease.

BACKGROUND/AIMS: As the prevalence of diabetes mellitus and its complications increase rapidly, diabetic foot ulcers (DFUs), which are a major diabetic complication, are expected to increase. For prevention and effective treatment, it is important to understand the clinical course of DFUs. The aim of this study was to investigate the natural course and predictors of amputation in patients with DFUs who required hospitalization. METHODS: A total of 209 patients with type 2 diabetes, aged 30 to 85 years, who visited emergency department or needed hospitalization due to DFUs were consecutively enrolled from May 2012 to January 2016, by retrospective medical record review. The main outcome was lower extremity amputation (LEA). RESULTS: Among 192 patients who completed follow-up, 113 patients (58.9%) required LEAs. Compared to patients without amputation, baseline levels of white blood cell counts and C-reactive protein were higher in patients with amputation. In addition, bone and joint involvement was more frequently observed in patients with amputation. Multivariable regression analysis revealed that combined infection (odds ratio [OR], 11.39; 95% confidence interval [CI], 2.55 to 50.93; p = 0.001) and bone or joint involvement (OR, 3.74; 95% CI, 1.10 to 12.70; p = 0.035) were significantly associated with an increased risk of LEA. CONCLUSIONS: The depth of the wound and combined infection of DFU, rather than the extent of the wound, were significant prognostic factors of LEAs in patients with type 2 diabetes.

BACKGROUND: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. METHODS: We conducted a multicenter, prospective, non-interventional study. Patients with CHADS2 ≥ 1 and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. RESULTS: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had CHADS2 ≥ 2 and 83.6% had CHA2DS2-VASc ≥ 2. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. CONCLUSION: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.

Although narcotic analgesics are potent releasers of histamine, IgE-mediated allergic reactions to these drugs are rare. Here we report the case of a 56-year-old male who suffered from chronic urticarial and analgesics-induced skin rashes. He visited our allergy clinic to determine alternative analgesics before undergoing surgery. A drug provocation test showed a positive reaction to aspirin, but negative reactions to acetaminophen and celecoxib. Despite careful attention to his drug regimen, during surgery he developed generalized urticaria and flushing. Skin tests of allergy to latex, lidocaine, propofol, rocuronium, flomoxef, meperidine, palonosetron, pyridostigmine, and fentanyl yielded negative results, except for the prick and intradermal tests with meperidine. Thus, this patient had both an aspirin/non-steroidal anti-inflammatory drugs idiosyncrasy and an IgE-mediated hypersensitivity to meperidine.

BACKGROUND/AIMS: It remains unclear whether atrophic gastritis can affect dyspeptic symptoms. We aimed to investigate whether the extent of atrophic gastritis is associated with specific dyspeptic symptoms. METHODS: Consecutive adults in a routine health-checkup program were enrolled in the study. The extent of atrophic gastritis was classified into 3 groups based on the Kimura-Takemoto criteria; the gastritis with no or little atrophy (group A: C0), the gastritis with atrophy mainly in the antrum (group B: C1 and C2), and the gastritis with atrophy in the large area of the corpus (group C: C3 and O). Upper gastrointestinal symptoms were categorized into "typical reflux symptoms," "epigastric pain syndrome (EPS)-related symptoms," and "postprandial distress syndrome (PDS)-related symptoms." RESULTS: A total of 1827 patients (1009 males, mean age 45.1 years) were included in the analysis. The subgroups of atrophic gastritis were as follows: group A (n = 1218, 66.7%), group B (n = 392, 21.4%), and group C (n = 217, 11.9%). Typical reflux, EPS-related, and PDS-related symptoms were present in 10.5%, 19.8%, and 16.2% of the subjects, respectively. PDS-related and EPS-related symptoms were significantly more prevalent in the group C of male patients and the group B of female patients, respectively, compared with other groups. PDS-related and EPS-related symptoms were independently associated with the group C in males (OR, 2.123; 95% CI, 1.090-4.136) and the group B in females (OR, 2.571; 95% CI, 1.319-5.025), respectively. CONCLUSIONS: The extent of atrophic gastritis appears to affect the generation of specific dyspeptic symptoms in a gender-dependent manner.

BACKGROUND: Despite the wide use of knee radiography in children and adolescent patients visiting the outpatient clinic, there has been no analysis about the prevalence and type of incidental findings yet. This study was performed to investigate the incidental findings on knee radiographs in children and adolescents according to age. METHODS: A total of 1,562 consecutive patients younger than 18 years of age were included. They who visited Seoul National University Bundang Hospital's outpatient clinic with a chief complaint of knee pain or malalignment between 2010 and 2011. We reviewed the knee radiographs and analyzed the prevalence and type of incidental findings, such as metaphyseal lucent area, epiphyseal cortical irregularity, osteochondroma and Harris growth arrest line. RESULTS: The mean age of the patients was 10.2 years (range, 1 month to 18 years). We identified 355 incidental findings in 335 patients (21.4%) and 98 abnormal findings (6.3%). The most common incidental finding was metaphyseal lucent area (131, 8.4%), followed by epiphyseal cortical irregularity (105, 6.7%), Harris growth arrest line (75, 4.8%), and osteochondroma (44, 2.8%). An epiphyseal cortical irregularity tended to have a higher prevalence at younger age (p < 0.001) and the prevalences of metaphyseal lucent area and Harris growth arrest line were also higher at a younger age (p = 0.001 and p < 0.001, respectively). However, the osteochondroma tended to have a higher prevalence at an older age (p = 0.004). CONCLUSIONS: This study describes the incidental findings on knee radiographs in children and adolescents and provides effective information from a viewpoint of an orthopedic doctor. The authors recommend considering those incidental findings if unfamiliar findings appear on a knee radiograph in the pediatric outpatient clinic.

BACKGROUND: This study was undertaken to investigate the trends of orthopedic publications during the last decade, and to document the country of origin, journal, funding source, and language of contribution using PubMed. METHODS: Orthopedic articles published between 2000 and 2009 were retrieved from PubMed using the following search terms: "orthopaedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])" and "orthopedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])." The articles were downloaded in XML file format, which contained the following information: article title, author names, journal names, publication dates, article types, languages, authors' affiliations and funding sources. These information was extracted, sorted, and rearranged using the database's management software. We investigated the annual number of published orthopedic articles worldwide and the annual rate of increase. Furthermore, the country of publication origin, journal, funding source, and language of contribution were also investigated. RESULTS: A total of 46,322 orthopedic articles were published and registered in PubMed in the last 10 years. The worldwide number of published orthopedic articles increased from 2,889 in 2000 to 6,909 in 2009, showing an annual increase of 384.6 articles, or an annualized compound rate of 10.2%. The United States ranked highest in the number of published orthopedic articles, followed by Japan, the United Kingdom, Germany, and the Republic of Korea. Among the orthopedic articles published worldwide during the last 10 years, 37.9% pertained studies performed in the United States. Fifty-seven point three percent (57.3%) of articles were published in journals established in the United States. Among the published orthopaedic articles, 4,747 articles (10.2%) disclosed financial support by research funds, of which 4,688 (98.8%) articles utilized research funds from the United States. Most articles were published in English (97.2%, 45,030 articles). CONCLUSIONS: The number of published orthopedic articles has been increasing over the last decade. The number of orthopedic articles, journals publication, and funding sources were dominated by research conducted in the United States, while share and growth of Asian countries including Japan, the Republic of Korea, and China were notable.

In order to study the treatment of aneurysms, the technique of making experimental aneurysms in laboratory animals must be established. In our study, to examine the feasibility of making experimental aneurysm and selective angiography on the common carotid artery in rabbits and to determine the size of experimental aneurysm after surgery, saccular aneurysms were fashioned on the right common carotid artery in 17 rabbits using a vein pouch technique. Selective angiography of the common carotid artery was performed immediately after surgery, and at 1 week, 4 weeks, and 8 weeks after surgery. Also, histological changes in the aneurysms were observed. In 16 rabbits with established successful experimental aneurysm, no differences were found in diet intake and behavior before and after surgery. The patency of the carotid artery was confirmed by selective angiography. The average size of the aneurysm immediately after surgery was similar to that of 1 week postoperatively in selective angiography, however it increased with time at 4weeks and 8 weeks. Histologically, infiltration of inflammatory cells and hemorrhage were found at the junction of the carotid artery and the vein pouch at 1 week, which disappeared at 4 weeks and 8 weeks. This study suggests experimental saccular aneurysm using the vein pouch technique might form aneurysms similar to that of the human in its properties such as increment of size, and selective angiography might be suitable for assessment of experimental aneurysm. Therefore, this animal model may be suitable for investigating new treatment methodologies for human aneurysms.
