ABSTRACT
Objective@#Cardiac tamponade with hemodynamic collapse requires immediate treatment, and ultrasound-guided pericardiocentesis is the treatment of choice. Although an essential skill for emergency physicians, there is a lack of training. We created a phantom that could practice ultrasound-guided pericardiocentesis using readily available materials. The pros and cons of the materials used were then compared. @*Methods@#Cardiac tamponade phantoms were made from gelatin, and included a heart, liver, and rib cage. We conducted a model-specific satisfaction questionnaire targeting 15 emergency physicians. The questionnaire was designed to be answered on a Likert 5-point scale. @*Results@#Creating the gelatin model took 6 hours. At room temperature, the gelatin model was able to retain its shape for 3 days. Fifteen physicians participated in the questionnaire, comprising five subjects having actual pericardiocentesis experience. In the questionnaire, our model achieved high satisfaction with all questions. @*Conclusion@#In our study, the pericardiocentesis phantom made from gelatin could maintain its shape for a long time, there was better recognition of the needle tip, and the model was more similar to the actual cardiac tamponade situation. Considering these positive characteristics, we recommend the phantom as a model for pericardiocentesis training.
ABSTRACT
Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus, is threatening global health worldwide with unprecedented contagiousness and severity. The best strategy to overcome COVID-19 is a vaccine. Various vaccines are currently being developed, and mass vaccination is in progress. Despite the very encouraging clinical trial results of these vaccines, there is insufficient information on the safety and efficacy of vaccines for inflammatory bowel disease (IBD) patients facing various issues. After reviewing current evidence and international guidelines, the Korean Association for the Study of Intestinal Diseases developed an expert consensus statement on COVID-19 vaccination issues for Korean IBD patients. This expert consensus statement emphasizes that severe acute respiratory syndrome coronavirus 2 vaccination be strongly recommended for IBD patients, and it is safe for IBD patients receiving immunomodulatory therapy.
ABSTRACT
The normal function of vascular endothelial cells is an important foundation for maintaining vascular permeability， restricting inflammatory activities of the vascular wall， and balancing the coagulation and fibrinolytic system. Endothelial dysfunction caused by persistent damage from pathological factors is considered as an early and prominent event of diabetic macroangiopathy. In traditional Chinese medicine， the classical theory of "restraining excessiveness to acquire harmony" was originally a condensed generalization of the rule of generation， restriction， replacement and evolution in the natural world， revealing the internal regulation mechanism of the stable operation of things. Then it gradually evolved into an important rule to explain the physiological phenomena and pathological mechanism of human body and guide the treatment. Corresponding to the nature， the body homeostasis also requires to achieve a state of strong viscera function and inexhaustible Qi and blood generation under the rule of restriction and generation. The pathogenesis of diabetic macroangiopathy is the process of "the predominant one failing to restrict and the hyperactive one becoming harmful". The loss of restriction and generation of the five organs leads to powerless Qi transformation and， as a result， the Qi， blood and body fluid cannot be dispersed. Therefore， the Qi， blood and body fluid turn into phlegm and blood stasis， such as glucose and lipid metabolism disorder， oxidative stress， inflammatory response and high blood viscosity， and finally block the veins. Excessive phlegm and blood stasis cannot be resolved， instead they become harmful and invade the blood vessel， causing endothelial dysfunction and further resulting in diabetic macroangiopathy. Under the guidance of the theory of "restraining excessiveness to acquire harmony"， the method of "harmonizing viscera， eliminating pathogen and removing turbidity" can effectively regulate the function of vascular endothelial cells， thus playing a positive role in preventing and treating diabetic macroangiopathy. The mechanism may be related to reducing oxidative stress， inhibiting inflammation， limiting vascular smooth muscle proliferation， and reducing platelet adhesion.

ABSTRACT
Background@#Atopic dermatitis is a chronic, inflammatory disease affecting the skin including the scalp, nails, and lips. One of the main pathogenesis of atopic dermatitis is skin barrier impairment. Transepidermal water loss is a noninvasive measurement of water loss across the stratum corneum for assessing skin barrier function. @*Objective@#This study aimed to evaluate the skin barrier function of various skin sites including hairy skin, non-keratinized areas, and hard keratin in patients with atopic dermatitis. Furthermore, the relationship between the severity of atopic dermatitis and transepidermal water loss was investigated. @*Methods@#In total, 73 patients with atopic dermatitis and 65 age-matched healthy controls were included in this study. Transepidermal water loss was measured at 8 different skin sites including hairy skin (vertex, occiput), the cheek, non-keratinized area (lower lip), lateral side of the upper arm, flexor side of the forearm, extensor side of the forearm, and hard keratin (fingernail). The severity of atopic dermatitis was assessed using the eczema area and severity index. @*Results@#Transepidermal water loss was observed to be higher at all the measured sites including the scalp, nails, and lips of atopic dermatitis patients in comparison with that of the age-matched controls. Transepidermal water loss were correlated with the severity of atopic dermatitis in the cheek, lips, upper arm, and forearm. @*Conclusion@#Patients with atopic dermatitis have impaired skin barrier function, including in regions of hairy skin, non-keratinized areas, and hard keratin areas. Barrier dysfunction is associated with the severity of atopic dermatitis.
ABSTRACT
The area of endoscopic application has been continuously expanded since its introduction in the last century and the frequency of its use also increased stiffly in the last decades. Because gastrointestinal endoscopy is naturally exposed to diseased internal organs and contact with pathogenic materials, endoscopy mediated infection or disease transmission becomes a major concern in this field. Gastrointestinal endoscopy is not for single use and the proper reprocessing process is a critical factor for safe and reliable endoscopy procedures. What needed in these circumstances is a practical guideline for reprocessing the endoscope and its accessories which is feasible in the real clinical field to guarantee acceptable prevention of pathogen transmission. This guideline contains principles and instructions of the reprocessing procedure according to the step by step. And it newly includes general information and updated knowledge about endoscopy-mediated infection and disinfection. Multiple societies and working groups participated to revise; Korean Association for the Study of the Liver, the Korean Society of Infectious Diseases, Korean College of Helicobacter and Upper Gastrointestinal Research, the Korean Society of Gastroenterology, Korean Society of Gastrointestinal Cancer, Korean Association for the Study of Intestinal Diseases, Korean Pancreatobiliary Association, the Korean Society of Gastrointestinal Endoscopy Nurses and Associates and Korean Society of Gastrointestinal Endoscopy. Through this cooperation, we enhanced communication and established a better concordance. We still need more researches in this field and fill up the unproven area. And our guidelines will be renewed accordingly.
ABSTRACT
Objective@#To identify the difference of quantitative radiologic stenosis between a normal latency group and an abnormal latency group, and to investigate the association of dermatomal somatosensory-evoked potential (DSEP) with magnetic resonance imaging (MRI) findings of narrowing in patients with lumbar spinal stenosis (LSS). @*Methods@#We retrospectively reviewed the clinical records and P40 latencies of L5 DSEP of 40 patients with unilateral symptoms of LSS at the L4–5 disc level. Quantitative assessments of stenosis in lumbar spine MRI were performed with measurements of the anteroposterior diameter (APD), cross-sectional area (CSA) of the dural sac, ligamentous interfacet distance (LID), CSA of the neural foramen (CSA-NF), and subarticular zone width. Analyses were conducted through comparisons of radiologic severity between the normal and abnormal latency groups and correlation between radiologic severity of stenosis and latency of DSEP in absolute (APD <10 mm) and relative (APD <13 mm) stenosis. @*Results@#The radiologic severities of lumbar stenosis were not significantly different between the normal and abnormal latency groups. In absolute and relative stenosis, latency showed a significant negative correlation with APD (r=-0.539, r=-0.426) and LID (r=-0.459, r=-0.494). In patients with relative stenosis, a weak significant positive correlation was found between latency and CSA-NF (r=0.371, p=0.048). LID was the only significant factor for latency (β=-0.930, p=0.011). @*Conclusion@#The normal and abnormal DSEP groups showed no significant differences inradiologic severity. The latency of DSEP had a negative correlation with the severity of central stenosis, and LID was an influencing factor.
ABSTRACT
Objective@#To explore susceptibility genes for autism spectrum disorders (ASD).@*Methods@#Whole-exome sequencing was carried out for 60 family trios affected with sporadic ASD. Genetic variants discovered in over 10% of the patients were selected for genotype-phenotype correlation and pathway enrichment analysis using Phenolyzer software and metascape database. Combining gene-phenotypic scores, pathway-related genes associated with neural and neurite triggering were screened for the candidates.@*Results@#A total of 170 common variants were found to be associated with the ASD phenotype. Among these, there was only one high-confidence gene [SHANK2 (0.8146)] and four medium-confidence genes [ERBB2 (0.1322), LAMC3 (0.1117), PPFIA4 (0.1059), DISC1 (0.1002)]. Twenty-pathways and four biological processes were found to be statistically significant by pathway enrichment analysis, which included neuron projection morphogenesis (GO: 0048812), regulation of neuroblast proliferation (GO: 1902692), modulation of excitatory postsynaptic potential (GO: 0098815), and dendrite morphogenesis (GO: 0048813). Twenty-one genes were found to be closely associated with neurological and neurite triggering, among which only SHANK2, ERBB2, and DISC1 had above-medium confidence correlation scores with the ASD phenotypes.@*Conclusion@#Abnormal neuron projection morphogenesis (GO: 0048812) may be closely related to the occurrence of ASD. SHANK2, ERBB2, and DISC1 are susceptibility genes for ASD.

BACKGROUND/AIMS: This study aimed to evaluate the feasibility and efficacy of endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) using a core needle for hepatic solid masses (HSMs). Additionally, the study aimed to assess factors that influence the diagnostic accuracy of EUS-FNB for HSMs. METHODS: A retrospective analysis of patients who underwent EUS-FNB for the pathological diagnosis of HSMs was conducted between January 2013 and July 2017. The procedure had been performed using core needles of different calibers. The assessed variables were mass size, puncture route, needle type, and the number of needle passes. RESULTS: Fifty-eight patients underwent EUS-FNB for the pathologic evaluation of HSMs with a mean mass size of 21.4±9.2 mm. EUS-FNB was performed with either a 20-G (n=14), 22-G (n=29) or a 25-G core needle (n=15). The diagnostic accuracy for this procedure was 89.7%, but both specimen adequacy for histology and available immunohistochemistry stain were 91.4%. The sensitivity and specificity of EUS-FNB were 89.7% and 100%, respectively. There was one case involving bleeding as a complication, which was controlled with endoscopic hemostasis. According to the multivariate analysis, no variable was independently associated with a correct final diagnosis. CONCLUSIONS: EUS-FNB with core biopsy needle is a safe and highly accurate diagnostic option for assessing HSMs. There were no variable factors associated with diagnostic accuracy.

Managing acute pancreatitis is clinically challenging because of the generally poor patient condition, the variety of treatment options depending on the severity and complications, and the uncertainty of outcomes. Recently, the step-up approach, which involves less invasive initial treatment and more invasive subsequent treatment, where necessary, has been proposed as the mainstay of managing pancreatitis. This paper presents a case of a 57-year-old man with severe acute pancreatitis, who developed an unexpected fistula in the rectum, which was treated successfully using the step-up approach. In managing this case, the authors faced clinical challenges in determining the infection of necrotic tissue in the early phase of the disease, the optimal timing and method of drainage, and the fistula closure or repair technique. Successful management of this case using the step-up approach validated current recommendations and suggests that it is a reasonable treatment strategy for pancreatic-colonic fistulas. This case also highlights the importance of an awareness that pancreatitis-associated complications can develop in an unexpected manner.
