Background: This study aimed to compare the occurrence of adverse events (AEs) and disease flares after vaccination against coronavirus disease 2019 (COVID-19) and influenza in patients with autoimmune rheumatic diseases (ARDs). Methods: Between November 2021 and March 2022, a survey was conducted among patients with ARD who received COVID-19 and influenza vaccinations. The questionnaire included 11 mandatory and closed-ended questions, and the following items were collected: medical history, immunization history, type of vaccine, patient-reported AEs, flare-up of the underlying disease after vaccination, and a confirmed diagnosis of COVID-19 or influenza. We compared the occurrence of vaccine-related adverse reactions to the COVID-19 and influenza vaccines based on the survey results. Multivariate logistic regression analysis was used to identify the factors affecting AEs or disease flares and to compare the post-vaccine response to mixed and matched vaccines. Results: We analyzed 601 adults with ARD who received the COVID-19 vaccine, with a mean age of 49.6 years (80.5% female). A total of 255 participants (42.4%) received a complete course of primary vaccination, 342 (56.9%) completed the booster dose, and 132 (38.6%) received a mixed vaccine. The frequencies of AEs (188 [52.2%] vs. 21 [5.8%]; P< 0.001) and disease flares (58 [16.2%] vs. 5 [1.4%]; P < 0.001) after COVID-19 vaccination were significantly higher than those after influenza vaccination. In the risk factor analysis, previous allergic reaction to other vaccines (odds ratio, 1.95; confidence interval, 1.07–3.70; P = 0.034) was the only factor associated with the occurrence of AEs. There was no difference in the post-vaccine responses between the mixed and matched vaccines. Results: We analyzed 601 adults with ARD who received the COVID-19 vaccine, with a mean age of 49.6 years (80.5% female). A total of 255 participants (42.4%) received a complete course of primary vaccination, 342 (56.9%) completed the booster dose, and 132 (38.6%) received a mixed vaccine. The frequencies of AEs (188 [52.2%] vs. 21 [5.8%]; P < 0.001) and disease flares (58 [16.2%] vs. 5 [1.4%]; P < 0.001) after COVID-19 vaccination were significantly higher than those after influenza vaccination. In the risk factor analysis, previous allergic reaction to other vaccines (odds ratio, 1.95; confidence interval, 1.07–3.70; P = 0.034) was the only factor associated with the occurrence of AEs. There was no difference in the post-vaccine responses between the mixed and matched vaccines. Conclusion The results of the survey of patients with ARD revealed that patient-reported AEs and underlying disease flares after receiving the COVID-19 vaccine were significantly higher than those after the influenza vaccine.

Purpose: There has been little information about the impact of coronavirus disease 2019 (COVID-19) pandemic on esophagogastroduodenoscopy (EGD) and gastric cancer claims. This study aimed to measure the impact of COVID-19 pandemic on EGD and gastric cancer claims in South Korea. Materials and Methods: This nationwide, population-based study compared the claims data of EGD, gastric cancer, early gastric cancer (EGC), advanced gastric cancer (AGC) and gastric cancer operation in 2020 and 2021 (COVID-19 era) to those in 2019 (before COVID-19 pandemic). Results: The annual claims of EGD, gastric cancer, EGC, and AGC were reduced by 6.3%, 5.0%, 4.7%, and 3.6% in 2020 and by 2.2%, 1.0%, 0.6%, and 1.9% in 2021, respectively, compared to 2019. The amount of annual claims of gastric cancer operation was reduced by 8.8% in 2020, but increased by 0.9% in 2021, compared to those in 2019. The monthly claims of EGD, gastric cancer, EGC, AGC, and gastric cancer operation were mainly reduced in the first epidemic wave of COVID-19, but decreased in the 2nd to 4th epidemic wave. Compared to 2019, the monthly claim of EGD, gastric cancer, EGC, AGC, and gastric cancer operation were reduced by 28.8%, 14.3%, 18.1%, 9.2%, and 5.8% in March 2020 and by 17.2%, 10.8%, 10.3%, 7.2%, and 35.4% in April 2020, respectively. Conclusion Negative impact of the COVID-19 pandemic on EGD, gastric cancer, EGC, AGC, and gastric cancer operation was worst during the first surge of COVID-19, but decreased in the 2nd to 4th epidemic wave of the disease in 2020 and 2021.

OBJECTIVE: We investigated the prevalence of obsessive compulsive disorder (OCD) among patients with schizophrenia, as well as the differences in psychotic symptoms and suicidality between schizophrenia patients with and without OCD. METHODS: Seventy-one subjects with the DSM-IV diagnosis of schizophrenia were evaluated by the Structured Clinical Interview for DSM-IV Axis I disorders, the Yale-Brown Obsessive-compulsive Scale and the Positive and Negative Syndrome Scale. RESULTS: There were 20 (28.2%) OCD patients with schizophrenia among the 71 subjects, and these 20 had significantly more severe negative and total psychotic symptoms than the 51 subjects without OCD, as evaluated with PANSS. The schizophrenia subjects with OCD had a significantly higher, recent suicidal attempt rate than those without OCD. CONCLUSION: The results of this study suggest the possibility that OCD symptoms in schizophrenia may be related to negative symptoms and that the OC symptoms may be related to the impulsivity expressed as suicidal attempts.

PURPOSE: Several studies have reported that facial fractures were associated with traumatic brain injuries or cervical injuries. The purpose of this study was to analyze the relationship between the location of facial injury and traumatic brain hemorrhage in order to support future decisions for image evaluation in facial injury patients. METHODS: In this retrospective cohort study, we evaluated facial injury patients without external head trauma who visited the emergency department at our hospital between January 1, 2014 and October 31, 2014. We divided the cohort into 2 groups: Facial injury patients with associated traumatic brain hemorrhage and those without traumatic brain hemorrhage. We compared the factors related to traumatic brain hemorrhage, such as facial injury locations, mechanism of accident, types of wounds, altered mentality, headache, and loss of consciousness between the two groups. RESULTS: In 873 patients, 73 (8.36%) presented traumatic brain hemorrhage and the other 800 had no traumatic brain hemorrhage on a brain computed tomography (CT) scan. The rate of headache, loss of consciousness, altered mentality, traffic accident, fall down, fracture, temporal injury, frontal injury, multiple facial area injury, and upper facial area (frontal and upper orbital area) injury were higher in the traumatic brain hemorrhage group than in the non-traumatic brain hemorrhage group (p<0.05). The risk factors of traumatic brain hemorrhage were headache, loss of consciousness, altered mentality, facial bone fracture, and temporal area injury of the face. CONCLUSION: If a facial injury patient has any of the following factors temporal area injury, facial bone fracture, altered mentality, headache, and loss of consciousness, we have to evaluate the brain CT scan even if the patient had no external head injury.

Female phenotype of a 46,XY male may originates from male pseudohermaphroditism due to 17alpha-hydroxylase deficiency. Lack of cortisol increases adrenocorticotropic hormone (ACTH) and mineralocorticoid production, leading to low renin hypertention and hypokalemia. A 41-year-old phenotypic female presented primary amenorrhea and hypertension. In the hormonal profile, the levels of serum estradiol, testosterone, rennin, and cortisol were decreased and ACTH and deoxycorticosterone were increased. Laparoscopic bilateral gonadectomy was performed, and corticosteroid, antihypertensive drugs, and estrogen were administered. We report this case with a brief review of the literatures.

PURPOSE: It has been established that the subglottic transverse diameter (SD-T) is the narrowest portion of the pediatric airway. In this study, we aimed to measure SD-T using computed tomography (CT) among Korean pediatrics, and compare and verify the measured SD-T with several formulas for appropriate size of the cuffed endotracheal tube (ETT) in pediatrics. METHODS: This is a retrospective study of 364 children from 0 month to 10 years undergoing facial CT scan. The CT scans were performed in children with spontaneous respiration. We obtained SD-T by these CT scans, and compared them with the Motoyama's formula [internal diameter (ID, mm)=(age/4)+3.5], the formula by Khine et al [ID (mm)= (age/4)+3.0], and the formula by Kim et al [outer diameter (OD, mm)=0.01×age (month)+0.02×height (cm)+3.3]. The obtained ID by these formulas was converted to correspond with OD. RESULTS: SD-T had a strong association with age (Estimate=0.029, R²=0.853, p<0.001), weight (Estimate=0.108, R²=0.698, p<0.001), and height (Estimate=0.048, R²=0.854, p<0.001), according to a linear regression analysis. There was no difference of SD-T between males and females (p=0.636). The intraclass coefficients of OD by the Motoyama's formula and the formula by Khine et al with OD of the cuffed ETT by measured SD-T were high (0.910, p<0.001, 0.897, p<0.001). CONCLUSION: Age based formulas for the appropriate cuffed ETT could be sufficient for emergency endotracheal intubation in Korean pediatrics.

OBJECTIVE: Some reports have shown the gender-related clinical differences in Obsessive-compulsive disorder (OCD), but no study has yet been done in Korea. The purpose of this study was to investigate the gender-related differences of clinical features in the obsessive-compulsive patients in Korea. METHODS: Two hundred forty nine patients with OCD were included in this study; 180 subjects were male and 69 subjects were female. The two groups were analyzed in terms of demographic data including clinical variable, Y-BOCS (Yale-Brown Obsessive Compulsive Scale) scores, clinical course and treatment response. RESULTS: We found the earlier age at onset of OC symptoms in males and the more frequent washing and somatization type in female. There were no gender difference in comorbidity, clinical course and the treatment response. CONCLUSION: We could observe some of the gender-related clinical differences in Korean OCD patients. The further studies would be required to evaluate the gender difference in the long-term clinical course and therapeutic response of Korean OCD patients.

PURPOSE: Preclinical studies have shown that human epidermal growth factor receptor 2 (HER2) status is associated with resistance to radiotherapy (RT). In this study, we evaluated the overall survival of a T1N0M0 breast cancer cohort in Korea according to the use of RT and the HER2 status. METHODS: We analyzed data collected from 11,552 patients with invasive breast cancer who were enrolled in the Korean Breast Cancer Society Registration Program between 1999 and 2007. Data on the TNM stage, estrogen receptor status, progesterone receptor status, HER2 status, operation method, and the use of RT were analyzed. RESULTS: The median follow-up period was 51 months. A significant improvement in overall survival after RT was observed only in the HER2(-) group. In this group, the 10-year overall survival rate was 95.5% for patients who did not receive RT and 96.3% for patients who received RT (p=0.037). In contrast, in the HER2(+) group, RT was not associated with a survival benefit (p=0.887). Multivariate analysis showed that RT was significantly associated with a reduction in mortality in the HER2(-) group (hazard ratio, 0.738; 95% confidence interval, 0.549-0.993; p=0.045). CONCLUSION: We found that postoperative RT was not associated with a survival benefit in HER2(+) breast cancer patients, suggesting that HER2(+) breast cancers could be RT resistant.

OBJECTIVE: The purpose of this study was to compare the diagnostic accuracy of both ultrasonography (US) and magnetic resonance imaging (MRI) for the assessment of Morton neuroma. MATERIALS AND METHODS: Our study group was comprised of 20 neuromas from 17 patients, and the neuromas were confirmed on surgery following evaluation with US, MRI, or both US and MRI. The diagnostic criterion for Morton neuroma, as examined by US, was the presence of a round or ovoid, well-defined, hypoechoic mass. The diagnostic criterion, based on MR imaging, was a well defined mass with intermediate to low signal intensity on both the T1- and T2-weighted images. The retrospective comparison between the sonographic and MR images was done by two experienced radiologists working in consensus with the surgical and pathologic correlations. RESULTS: The detection rate of Morton neuroma was 79% for 14 neuromas from 11 patients who had undergone US followed by an operation. The detection rate was 76% for 17 neuromas from 15 patients who had undergone MRI and a subsequent operation. The mean size of the examined neuromas was 4.9 mm on the US images and it was 5.1 mm on the MRI studies. Ten neuromas (71%) were 5 mm or less as measured by US, and three neuromas were not detected, whereas on the MRI analysis, 10 neuromas (59%) were 5 mm or less and four neuromas were not visualized. Among the patients examined during postoperative follow-up, symptoms were completely relieved in 85% and the symptoms were partially relieved in 15%. CONCLUSION: US and MR imaging are comparable modalities with high detection rate for the evaluation of Morton neuroma.

PURPOSE: Previous reports show an association between high serum ferritin levels and metabolic syndrome (MS) in adults. In adolescents, little information is available with obesity and serum ferritin levels. METHODS: This is a cross-sectional study. Data were obtained from the 5th Korean National Health and Nutrition Examination Survey (K-NHANES) conducted during 2010 by the Korean Ministry of Health and Welfare. A total of 849 subjects aged 10-18 years participated in the 2010 survey. A body mass index (BMI) > or =95th percentile for age and sex or a BMI > or =25 was used to diagnose as obesity. RESULTS: The weighted prevalence of obesity was 13.4% (62/462) in male and 8.5% (33/387) in female. We observed significantly higher serum ferritin in male than in female (mean+/-standard error [SE], 50.5+/-2.3 microU/L vs. 30.6+/-1.3 microU/L; P<0.0001). In male, serum ferritin is positively correlated with age (P<0.0001). White blood cell (WBC) count, serum fasting blood sugar, triglyceride (TG), total cholesterol, low-density lipoprotein, insulin, homeostasis model assessment-insulin resistance (HOMA-IR), systolic and diastolic blood pressure, and ferritin levels were higher and high-density lipoprotein (HDL) were lower in the obesity than in the normal group. In female adolescents, WBC count, TG, insulin, and HOMA-IR were higher and HDL were lower in the obesity than in the normal group. In male, serum ferritin levels showed positive association with obesity (beta=21.196, P=0.016). CONCLUSION: Serum ferritin levels appear to be associated with obesity in Korean male adolescents.
