ABSTRACT

Background/Aims@#The study aimed to investigate the current practice patterns in the management of pancreatic cystic neoplasms in Korea. @*Methods@#An electronic survey was systematically distributed by email to members of the Korean Pancreatobiliary Association from December 2019 to February 2020. @*Results@#In total, 115 (110 gastroenterologists, five surgeons) completed the survey, 72.2% of whom worked in a tertiary/academic medical center. Most (65.2%) followed the 2012/2017 International Association of Pancreatology guidelines for the management of pancreatic cystic neoplasms. A gadolinium-enhanced magnetic resonance imaging/magnetic resonance cholangiopancreatography was the most common first-line diagnostic modality (42.1%), but a contrast-enhanced computed tomography scan was preferred as a subsequent surveillance tool (58.3%). Seventy- four percent of respondents routinely performed endoscopic ultrasound-guided fine needle aspiration for pancreatic cystic neoplasms with suspicious mural nodules. Endoscopic ultrasound-guided fine needle aspiration cytology (94.8%) and cystic fluid carcinoembryonic antigen (95.7%) were used for cystic fluid analysis. Most (94%) typically recommended surgery in patients with high-risk stigmata, but 18.3% also considered proceeding with surgery in patients with worrisome features. Most (96.5%) would continue surveillance of pancreatic cystic neoplasms for more than 5 years. @*Conclusions@#According to this survey, there was variability in the management of pancreatic cystic neoplasms among the respondents. These results suggest that the development of evidence-based guidelines for pancreatic cystic neoplasms that fit the Korean practice is needed to create an optimal approach to the management of pancreatic cystic neoplasms.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at Shenmen (HT 7) and Sanyinjiao (SP 6) on anxiety and depression in patients with insomnia, and to explore the mechanism of its compatibility effect.@*METHODS@#Ninety patients of insomnia were randomly divided into a combination group, a Shenmen group and a Sanyinjiao group, 30 cases in each group. In addition, 37 cases with anxiety (12 cases in the combination group, 13 cases in the Shenmen group and 12 cases in the Sanyinjiao group) and 42 cases with depression (14 cases in the combination group, 14 cases in the Shenmen group and 14 cases in the Sanyinjiao group) were identified. The patients in the combination group, Shenmen group and Sanyinjiao group were treated with EA (dilatational wave, frequency of 5 Hz/25 Hz) at Shenmen (HT 7)-Sanyinjiao (SP 6), Shenmen (HT 7) and Sanyinjiao (SP 6), respectively, 30 min each treatment, once a day. The consecutive 5 days of treatments were taken as a course of treatment, and 2 courses of treatment were given. The insomnia severity index (ISI), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores were evaluated before and after treatment, and the serum contents of dopamine (DA) and norepinephrine (NE) were measured.@*RESULTS@#Compared before treatment, the ISI, SAS and SDS scores in the three groups were all decreased after treatment (P<0.05), and the ISI score in the combination group was lower than that in the Shenmen group (P<0.05). Among the patients with anxiety, compared before treatment, the ISI, SAS scores and serum contents of DA were all decreased after treatment in the three groups (P<0.05), and the serum contents of NE in the combination group and Shenmen group were decreased after treatment (P<0.05); the SAS score and serum contents of NE in the combination group and Shenmen group as well as the ISI score in the combination group were lower than those in the Sanyinjiao group (P<0.05). Among the patients with depression, compared before treatment, the ISI, SDS scores and serum contents of DA were all decreased after treatment in the three groups (P<0.05), and the serum contents of NE in the combination group and Shenmen group were decreased after treatment (P<0.05); the ISI, SDS scores and serum contents of NE in the combination group as well as SDS score in the Shenmen group were lower than those in the Sanyinjiao group (P<0.05).@*CONCLUSION@#EA at Shenmen (HT 7) and Sanyinjiao (SP 6) has advantages over EA at Sanyinjiao (SP 6) on improving insomnia, anxiety and depression. Shenmen (HT 7) plays a major role in improving anxiety and depression. Shenmen (HT 7) and Sanyinjiao (SP 6) may play a compatibility effect of regulating consciousness and sleeping by reducing the level of serum NE.

ABSTRACT

Background/Aims@#There are few studies describing contemporary status of mechanical ventilation in Korea. We investigated changes in management and outcome of mechanical ventilation in Korea. @*Methods@#International, prospective observational cohort studies have been conducted every 6 years since 1998. Korean intensive care units (ICUs) participated in 2010 and 2016 cohorts. We compared 2016 and 2010 Korean data. @*Results@#Two hundred and twenty-six patients from 18 ICUs and 275 patients from 12 ICUs enrolled in 2016 and 2010, respectively. In 2016 compared to 2010, use of non-invasive ventilation outside ICU increased (10.2% vs. 2.5%, p = 0.001). Pressure-control ventilation was the most common mode in both groups. Initial tidal volume (7.1 mL/kg vs. 7.4 mL/kg, p = 0.372) and positive end-expiratory pressure (6 cmH2O vs. 6 cmH2O, p = 0.141) were similar, but peak pressure (22 cmH2O vs. 24 cmH2O, p = 0.011) was lower in 2016. More patients received sedatives (70.7% vs. 57.0%, p = 0.002) and analgesics (86.5% vs. 51.1%, p < 0.001) in 2016. The awakening (48.4% vs. 31.0%, p = 0.002) was more frequently attempted in 2016. The accidental extubation rate decreased to one tenth of what it was in 2010 (1.1% vs. 10.2%, p < 0.001). The ICU mortality did not change (31.4% 35.6%, p = 0.343) but ICU length of stay showed a decreasing trend (9 days vs. 10 days, p = 0.054) in 2016. @*Conclusions@#There were temporal changes in care of patients on mechanical ventilation including better control of pain and agitation, and active attempt of awakening.

ABSTRACT

Endoscopic ultrasonography-guided intervention has gradually become a standard treatment for peripancreatic fluid collections (PFCs). However, it is difficult to popularize the procedure in Korea because of restrictions on insurance claims regarding the use of endoscopic accessories, as well as the lack of standardized Korean clinical practice guidelines. The Korean Society of Gastrointestinal Endoscopy (appointed a Task Force to develope medical guidelines by referring to the manual for clinical practice guidelines development prepared by the National Evidence-Based Healthcare Collaborating Agency. Previous studies on PFCs were searched, and certain studies were selected with the help of experts. Then, a set of key questions was selected, and treatment guidelines were systematically reviewed. Answers to these questions and recommendations were selected via peer review. This guideline discusses endoscopic management of PFCs and makes recommendations on indication for the procedure, pre-procedural preparations, optimal approach for drainage, procedural considerations (e.g., types of stent, advantages and disadvantages of plastic and metal stents, and accessories), adverse events of endoscopic intervention, and procedural quality issues. This guideline was reviewed by external experts and suggests best practices recommended based on the evidence available at the time of preparation. This will be revised as necessary to address advances and changes in technology and evidence obtained in clinical practice and future studies.

ABSTRACT

We present the case of a 78-year-old female who experienced acute mental deterioration after vomiting. She showed severe hypercapnia without definite lung disease and hypoxic injury on brain image. After the acute period, she still had excessive daytime sleepiness, and the hypercapnia aggravated during the night. Polysomnography revealed severe obstructive sleep apnea, a sleep-related breathing disorder with a high apneahypopnea index of 60.2/h (mainly a hypopnea index of 59.0/h). She was diagnosed with combined obesity hypoventilation syndrome (OHS) and sleep-related breathing disorder, as the cause of daytime hypercapnia and excessive daytime sleepiness. Three months of successful bi-level positive airway pressure (BiPAP) therapy dramatically improved her daytime sleepiness and cognition. This case suggests that patients with OHS can be susceptible to hypoxic brain damage, and emphasizes the importance of the recognition and diagnosis of OHS and appropriate treatment with BiPAP therapy.

ABSTRACT

Background/Aims@#Endoscopic ultrasonography (EUS) provides high-resolution images and is superior to computed tomography (CT) scan in diagnosing small pancreatic ductal adenocarcinoma (PDAC). As a result, the use of EUS for early detection of PDAC has attracted attention. This study aimed to identify the clinical and radiological characteristics of patients with PDAC diagnosed by EUS but not found on CT scan. @*Methods@#The medical records of patients diagnosed with PDAC at 12 tertiary referral centers in Korea from January 2003 to April 2019 were reviewed. This study included patients with pancreatic masses not clearly observed on CT scan but identified on EUS. The clinical characteristics and radiological features of the patients were analyzed, and survival analysis was performed. @*Results@#A total of 83 patients were enrolled. The most common abnormal CT findings other than a definite mass was pancreatic duct dilatation, which was identified in 61 patients (73.5%). All but four patients underwent surgery. The final pathologic stages were as follows: IA (n=31, 39.2%), IB (n=8, 10.1%), IIA (n=20, 25.3%), IIB (n=17, 21.5%), III (n=2, 2.5%), and IV (n=1, 1.4%). The 5-year survival rate of these patients was 50.6% (95% confidence interval, 38.8% to 66.7%). Elevated liver function testing and R1 resection emerged as significant predictors of mortality in the multivariable Cox regression analysis. @*Conclusions@#This multicenter study demonstrated favorable long-term prognosis in patients with PDAC diagnosed by EUS but indeterminate on CT scan. EUS should be considered for patients with suspected PDAC but indeterminate on CT scan.

ABSTRACT

Wireless intraoperative load sensors have been used to improve the quality of soft-tissue balancing during total knee arthroplasty (TKA). Recent studies using the sensors have demonstrated reductions in gap imbalance, as well as early improvement of patientreported clinical outcomes and low rates of arthrofibrosis. However, well-designed prospective studies are needed to determine whether the application of the sensor technology for TKA will have clinical benefits and improve the survival of prosthesis. Knowledge of the load-sensing technology (advantages and disadvantages, potential pitfalls, and future prediction) is crucial to apply this new TKA technique successfully. Herein, we conduct a narrative review of previous studies on this technique.

ABSTRACT

Paradoxical reactions in patients treated with tumor necrosis factor-alpha inhibitors (TNFis) have an estimated prevalence of 1.5% to 5%. Such reactions usually present as psoriasiform eruptions on the trunk and extremities along with palmar and flexural involvement. When affecting the scalp, new-onset psoriasis induced by TNFi can result in non-scarring or scarring alopecia. Although the paradoxical reaction was first reported in 2003, this TNFi-associated psoriatic alopecia (TiAPA) has been recently reported with increasing frequency. This condition is characteristically reversible and requires clinical and histopathological identification from other diseases for proper treatment. The cessation of TNFi therapy may not be mandatory, and decision to continue TNFi therapy depends on the severity of TiAPA and the riskbenefit ratio of treatment modification on the underlying disease. Herein, we report a case of TiAPA in a patient with inflammatory bowel disease whose alopecia improved following suspension of TNFi. We also describe the clinical and histopathological diagnostic criteria based on review of the literature.

ABSTRACT

Objective To analyze the staff structure, turnover and income of human resources in disease control and prevention institutions(CDCs)at different levels in China, to identify the existing problems, and to make policy recommendations accordingly. Methods A questionnaire survey was used to collect the data on the staff of CDCs at different levels in China from 2016 to 2018. Descriptive analysis and trend analysis were conducted on the number of staff, recruitment and turnover, income and other indicators in the three years. Results A total of 606 CDCs were included in the study. The proportion of job openings was 11.97% in 2018. Although the median proportion of professional personnel and health professional personnel in the CDCs reached the national standard(85% and 70%, respectively), a considerable number of institutions failed to meet the national standard. From 2016 to 2018, staff turnover in the CDCs has been increasing, with a minimum of 0.73(in 2016, municipal CDCs)and a maximum of 10.52(in 2018, provincial CDCs). In the staff who quit the CDCs, the proportion of junior professionals was the highest, while that of medium and senior professional increased gradually. Of them, the proportion of staff with graduate education in eastern China and provincial CDCs was higher than that of undergraduate education, while the proportion of staff with graduation education in other regions also increased. From 2016 to 2018, the average annual income in the CDCs in most regions did not reach the national average wage level of urban employees in health, social security and social welfare field in the same period. In county and district level CDCs in central and western China, personal income in 2018 was even less than the national average wage level in 2016. Conclusion Human resources in the CDCs at different levels in China remains insufficient and unbalanced, which warrants a"supporting policy"mechanism for public health personnel. The loss of the personnel in the CDCs continues to increase, in which the loss of senior professionals become increasingly serious. It raises a new concern to establish and improve the incentive mechanism of public health personnel. Furthermore, personal income in the CDCs is lower than the local average level. It is necessary to set personal income reasonably according to local economic level.

ABSTRACT

Background@#Emergency departments (EDs) generally receive many casualties in disaster or mass casualty incidents (MCI). Some studies have conceptually suggested the surge capacity that ED should have; however, only few studies have investigated measurable numbers in one community. This study investigated the surge capacity of the specific number of accommodatable patients and overall preparedness at EDs in a metropolitan city. @*Methods@#This cross-sectional study officially surveyed surge capacity and disaster preparedness for all regional and local emergency medical centers (EMC) in Seoul with the Seoul Metropolitan Government's public health division. This study developed survey items on space, staff, stuff, and systems, which are essential elements of surge capacity. The number of patients acceptable for each ED was investigated by triage level in ordinary and crisis situations. Multivariate linear regression analysis was performed on hospital resource variables related to surge capacity. @*Results@#In the second half of 2018, a survey was conducted targeting 31 EMC directors in Seoul. It was found that all regional and local EMCs in Seoul can accommodate 848 emergency patients and 537 non-emergency patients in crisis conditions. In ordinary situations, one EMC could accommodate an average of 1.3 patients with Korean Triage and Acuity Scale (KTAS) level 1, 3.1 patients with KTAS level 2, and 5.7 patients with KTAS level 3. In situations of crisis, this number increased to 3.4, 7.8, and 16.2, respectively. There are significant differences in surge capacity between ordinary and crisis conditions. The difference in surge capacity between regional and local EMC was not significant. In both ordinary and crisis conditions, only the total number of hospital beds were significantly associated with surge capacity. @*Conclusion@#If the hospital's emergency transport system is ideally accomplished, patients arising from average MCI can be accommodated in Seoul. However, in a huge disaster, it may be challenging to handle the current surge capacity. More detailed follow-up studies are needed to prepare a surge capacity protocol in the community.

ABSTRACT

Endoscopic ultrasound (EUS)-guided tissue acquisition of pancreatic solid tumor requires a strict recommendation for its proper use in clinical practice because of its technical difficulty and invasiveness. The Korean Society of Gastrointestinal Endoscopy (KSGE) appointed a task force to draft clinical practice guidelines for EUS-guided tissue acquisition of pancreatic solid tumor. The strength of recommendation and the level of evidence for each statement were graded according to the Minds Handbook for Clinical Practice Guideline Development 2014. The committee, comprising a development panel of 16 endosonographers and an expert on guideline development methodology, developed 12 evidence-based recommendations in eight categories intended to help physicians make evidence-based clinical judgments with regard to the diagnosis of pancreatic solid tumor. This clinical practice guideline discusses EUS-guided sampling in pancreatic solid tumor and makes recommendations on circumstances that warrant its use, technical issues related to maximizing the diagnostic yield (e.g., needle type, needle diameter, adequate number of needle passes, sample obtaining techniques, and methods of specimen processing), adverse events of EUS-guided tissue acquisition, and learning-related issues. This guideline was reviewed by external experts and suggests best practices recommended based on the evidence available at the time of preparation. This guideline may not be applicable for all clinical situations and should be interpreted in light of specific situations and the availability of resources. It will be revised as necessary to cover progress and changes in technology and evidence from clinical practice.

ABSTRACT

Background@#One recently developed total knee arthroplasty (TKA) prosthesis was designed to alter the patellofemoral geometry and optimize patellar tracking compared to its predecessor. Despite an expectation that the improved design would contribute to optimal patellofemoral compatibility, its effect has not been confirmed with patellofemoral-specific clinical scoring systems and radiographic parameters. Our purpose was to compare patellofemoral-specific clinical and radiographic results after TKA using a patellofemoral design-modified prosthesis and its predecessor. @*Methods@#The results of 200 TKAs with Attune (group A) were compared to those of 200 TKAs with PFC Sigma (group B). Clinically, the presence of anterior knee pain (AKP), patellar crepitation, and Kujala score were checked. Radiographically, anterior femoral offset (AFO), posterior femoral offset (PFO), position of patellar ridge, and patellar tilt and translation were compared. @*Results@#In group A, AKP and patellar crepitation occurred less frequently (AKP: 3% vs. 8%, p = 0.028; patellar crepitation: 2.5% vs. 9%, p = 0.005) and Kujala score was higher (81.8 vs. 77.9, p < 0.001), when compared to group B. The AFO decreased in group A postoperatively but increased in group B (–1.2 vs. 1.1 mm, p < 0.001). The change in PFO was smaller in group A than group B (–1.2 vs. –3.6 mm, p < 0.001). The change in patellar ridge after TKA was smaller in group A than group B (1.4% vs. 8.3%, p < 0.001).The postoperative patella of group A was more laterally tilted (5.9° vs. 2.2°, p < 0.001) and less laterally translated (0.9 vs. 2.6 mm, p < 0.001). The proportion of incompatible patella tilt angle (≥ ± 10°) was greater in group A than group B (21.7% vs. 4.5%, p < 0.001). @*Conclusions@#TKA using Attune provided better patellofemoral-specific clinical results and favorable radiographic parameters related with patellar ridge, AFO, and PFO than TKA using PFC Sigma did. However, the current prosthesis did not provide better radiographic patellar tracking, which might be due to the medial location of the patellar ridge.

ABSTRACT

Objective@#Among the pediatric population with minor head trauma, it is difficult to determine an indication for the usage of brain computerized tomography (CT). Our study aims to compare the efficiency of the most commonly used clinical decision rules: the Pediatric Emergency Care Applied Research Network (PECARN) and Canadian Assessment of Tomography for Childhood Head Injury 2 (CATCH2). @*Methods@#This retrospective study investigated whether the PECARN and CATCH2 rules were applicable to Korean children with minor head trauma for reducing the use of brain CT imaging, while detecting intracranial pathology. @*Results@#Overall, 251 patients (0–5 years old) admitted to emergency rooms within 24 hours of injury were included between August 2015 to August 2018. The performance results are as follows: the PECARN and CATCH2 rules had a sensitivity of 80.00% (51.91%–95.67%) and 100% (78.20%–100.00%) with a specificity of 28.39% (22.73%–34.60%) and 15.25% (10.92%–20.49%), respectively; the negative predictive values were 98.58% and 100%, respectively. Overall, the CATCH2 rule was more successful than the PECARN rule in detecting intracranial pathology; however, there was no significant difference between them. Furthermore, the PECARN and CATCH2 rules lowered the rate of head CT imaging in our study group. @*Conclusion@#Both the rules significantly lowered the rate of indicated brain CT. However, since the CATCH2 rule had higher sensitivity and negative predictive value than the PECARN rule, it is more appropriate to be used in emergency rooms for detecting intracranial pathology in children with minor head trauma.

ABSTRACT

Objective@#Delivery of prehospital defibrillation for shockable rhythms by emergency medical service providers is crucial for successful resuscitation in out-of-hospital cardiac arrest (OHCA) patients. The optimal range of prehospital defibrillation attempts for refractory shockable rhythms is unknown. This study evaluated the association between the number of prehospital defibrillation attempts and neurologic outcomes in OHCA patients. @*Methods@#A retrospective observational study was conducted using the nationwide OHCA registry. Adult OHCA patients who were treated by emergency medical service providers due to presumed cardiac origin with initial shockable rhythm were enrolled from 2013 to 2016. The final analysis was performed on patients without on-scene return of spontaneous circulation. The number of prehospital defibrillation attempts was categorized as follows: 2–3, 4–5, and ≥6 attempts. The primary outcome was a good neurologic recovery at hospital discharge. Multivariate logistic regression analysis was performed to evaluate the association between neurologic outcomes and the number of prehospital defibrillation attempts. @*Results@#A total of 4,513 patients were included in the final analysis. The numbers of patients for whom 2–3, 4–5, and ≥6 defibrillation attempts were made were 2,720 (60.3%), 1,090 (24.2%), and 703 (15.5%), respectively. Poorer outcomes were associated with ≥6 defibrillation attempts: survival to hospital discharge (adjusted odds ratio, 0.38; 95% confidence interval, 0.21–0.65) and good neurologic recovery (adjusted odds ratio, 0.42; 95% confidence interval, 0.21–0.84). @*Conclusion@#Six or more prehospital defibrillation attempts were associated with poorer neurologic outcomes in OHCA patients with an initial shockable rhythm who were unresponsive to on-scene defibrillation and resuscitation.

ABSTRACT

Purpose@#This study evaluated the efficacy of adjuvant chemotherapy (AC) in patients with resected ampulla of Vater (AoV) carcinoma. @*Materials and Methods@#Data from 646 patients who underwent surgical resection at Asan Medical Center between 2000 and 2017 were retrospectively reviewed. @*Results@#The median age of the patients was 62 years, and 54.2% were male. Patients were classified into AC group (n=165, 25.5%) and no AC group (n=481, 74.5%). With a median follow-up duration of 88 months, in patients with stage I, II, III, median recurrence-free survival (RFS) was not reached, 44 months, and 15 months, respectively, and the median overall survival (OS) were not reached, 88 months and 35 months, respectively. Despite no statistical significance, RFS and OS were better in stage II patients with AC than in those without AC (median RFS, 151 months vs. 38 months; p=0.156 and median OS, 153 months vs. 74 months; p=0.299). In multivariate analysis for RFS and OS, TNM stage, R1 resection status, presence of lymphovascular invasion, and perineural invasion remained significant factors, whereas AC (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.54 to 1.00; p=0.052) was marginally related with RFS. After propensity score matching in only stage II/III patients, RFS and OS with AC were numerically longer than those without AC (HR, 0.80; 95% CI, 0.60 to 1.06; p=0.116 and HR, 0.77; 95% CI, 0.56 to 1.06; p=0.111). @*Conclusion@#AC with fluoropyrimidine did not improve survival of patients with resected AoV carcinoma. However, multivariate analysis with prognostic factors showed a marginally significant survival benefit with AC.

ABSTRACT

Abstract@#The health of children and adolescents is not only related to the growth and wellbeing of individuals, but also to the construction and development of countries. This study reviewed policies that were issued by the central government since the founding of New China which focused on the prevention and treatment of common diseases among school-age children and adolescents. The results revealed that, since the founding of New China, policies for the prevention and control of common diseases among school-age children and adolescents increased in number, and they began to focus on specific rather than general health problems. A gradual emphasis was placed on the specific implementation of prevention and control measures, rather than on guiding principles. Increasingly more attention has been paid to the prevention and treatment of common diseases among school-age children and adolescents.

ABSTRACT

Background/Aims@#The coronavirus disease 2019 (COVID-19) outbreak caused numerous social and cultural changes, but few studies focused on their effects on gastroenterology (GI) fellowship training. This study evaluated the impact of COVID-19 on GI fellowship training. @*Methods@#A web-based questionnaire was sent out to GI fellows in Korea between 15 February and 15 March 2021. The questionnaire included questions regarding the characteristics of GI fellows, perception of COVID-19 outbreak, impact of COVID-19 outbreak, and telemedicine on the education of a GI fellowship. @*Results@#Among 111 answers, 94 respondents were analyzed. The GI fellows were provided with sufficient information about the COVID-19 outbreak (74.7%), well educated, and provided with personal protective equipment use (74.7% and 83.9%, respectively).On the other hand, outpatient schedule and volume decreased in 25.5% and 37.8% of respondents, respectively. Moreover, endoscopy sessions and volume decreased in 51.1% and 65.6% of respondents, respectively. As a result, 78.9% of respondents were concerned that the COVID-19 outbreak adversely affected their education. Telemedicine utilization was introduced during the COVID-19 outbreak, but only 20.0% and 10.6% of respondents agreed that telemedicine has benefits from the patient’s and doctor’s perspectives, respectively. In addition, only 25.9% of respondents were willing to continue telemedicine if adequately reimbursed, and 68.2% of respondents were concerned that it adversely affected their education. @*Conclusions@#The COVID-19 outbreak has adversely affected GI fellowship training in Korea for outpatient clinics, gastrointestinal endoscopy, educational conferences, and telemedicine. This study highlights that GI fellowship training needs more attention in the COVID-19 outbreak.
