Background: Remimazolam is a novel short-acting benzodiazepine that has recently been used for general anesthesia. This study compared the safety and efficacy of remimazolam-based total intravenous anesthesia (TIVA) and volatile agent-based anesthesia in adults undergoing general anesthesia. Methods: We searched electronic databases including PubMed, Embase, CENTRAL, and Scopus for relevant studies. The primary outcome was the proportion of patients who experienced hypotension during surgery. Secondary outcomes included incidence of bradycardia, extubation time, duration in the post-anesthesia care unit hospital stay, and incidence of postoperative nausea and/or vomiting (PONV). We estimated the relative risk (RR) and mean difference with 95% CIs using a random-effects model. Results: A total of 969 patients from 12 randomized controlled trials were included. The incidence of hypotension was 14% and 34% in the remimazolam and volatile agent groups, respectively. Remimazolam significantly lowered the incidence of hypotension (RR: 0.43, 95% CI [0.29–0.63], P = 0.0000, I2 = 26%). The remimazolam group had a PONV incidence of 13%, compared to 28% in the volatile agent group, indicating a significant difference (RR: 0.51, 95% CI [0.37–0.72], P = 0.0001, I2 = 15%). No significant differences were observed in the other outcomes. Conclusions Remimazolam-based TIVA demonstrated favorable hemodynamic effects, with a lower incidence of hypotension and similar bradycardia rates, compared to volatile agent-based anesthesia. Furthermore, the reduction in PONV supports the use of remimazolam-based TIVA as a valuable method for general anesthesia.

Purpose: Sixty to eighty percent of children with egg allergy are able to tolerate eggs in baked form. The purpose of this study was to evaluate the clinical usefulness and diagnostic value of measurements of IgE specific to egg white, ovalbumin, and ovomucoid for reactivity to baked egg in children with sensitivity to egg. Methods: Two hundred seventeen children with suspected egg allergy underwent open food challenges with baked egg (in the form of muffins). The outcomes of the challenges were compared to the serum concentrations of IgE specific to egg white, ovalbumin, and ovomucoid by using ImmunoCAP. Results: There were no statistically significant differences in levels of IgE specific to egg white, ovalbumin, and ovomucoid between the baked egg challenge positive and negative groups younger than 2 years (n = 163). However, significant differences were observed between the challenge positive and negative groups in 54 subjects aged 2 to 5 years (all P < 0.05). The optimal cutoff points of egg white, ovalbumin, and ovomucoid specific IgE levels among children aged 2 to 5 years were 12.40 kU A/L (sensitivity 79%, specificity 66%), 4.07 kU A/L (sensitivity 88%, specificity 58%), and 3.65 kU A/L (sensitivity 77%, specificity 62%), respectively. Conclusion The level of IgE specific to egg white and its components can predict the reactivity to baked egg in children aged 2 to 5years.

Background/Aims: Controversy regarding the effectiveness of neoadjuvant therapy for resectable pancreatic ductal adenocarcinoma (PDAC) still exists. Here, we aimed to identify the potential benefits of neoadjuvant therapy followed by surgery for resectable PDAC. Methods: We reviewed radiologically resectable PDAC patients who received resection with curative intent at a tertiary hospital in South Korea between January 2012 and August 2019. A total of 202 patients underwent curative resection for resectable PDAC: 167 underwent surgical resection first during this period, and 35 received neoadjuvant chemotherapy/chemoradiation therapy followed by surgery. Resectable PDAC patients were subdivided, and 1:3 propensity score matching (PSM) was performed to reduce selection bias. Results: Compared with the group that received surgery first, the group that received neoadjuvant treatment followed by surgery had significantly smaller tumors (22.0 mm vs 27.0 mm, p=0.004), a smaller proportion of patients with postoperative pathologic T stage (p=0.026), a smaller proportion of patients with lymphovascular invasion (20.0% vs 40.7%, p=0.022), and a larger proportion of patients with negative resection margins (74.3% vs 51.5%, p=0.049). After PSM, the group that received neoadjuvant therapy had a significantly longer progression-free survival than those in the group that underwent surgery first (29.6 months vs 15.1 months, p=0.002). Overall survival was not significantly different between the two groups after PSM analysis. Conclusions We observed significantly better surgical outcomes and progression-free survival with the addition of neoadjuvant therapy to the management of resectable PDAC. However, despite PSM, there was still selection bias due to the use of different regimens between the groups receiving surgery first and neoadjuvant therapy. Large homogeneous samples are needed in the future prospective studies.

This study was performed to select the proper assessing methods for learning outcomes in undergraduate education of medical humanities (MH), and to evaluate whether student assessments in MH curricula are related to the graduate outcomes (GO)and/or periodic phase outcomes (PO). We searched the reasonable assessing methods for GO and PO of MH curricula of Keimyung University School of Medicine (KUSM). The outcomes are composed of six competencies including patient care, communication, patient support, professionalism, problem solving and research, and self-development. Then, we analyzed whether student assessments carried out during formal MH curricula properly achieved their PO, furthermore their GO. Four competencies including communication, patient support, professionalism, self-development were lightened to be closely related to outcomes for MH. Only the component of problem solving was settled to be related to MH in the competency of problem solving and research. The competency of patient care was excluded from the relationship with MH. The assessing methods for the GO and three PO recommended from educational experts, and there were various available assessing methods based on medical situations and clinical contexts including direct observation of clinical skills, 360 degree feedback, peer review, self-assessment, project-based assessment, portfolio-based assessment, discussion & presentation-based assessment, log-based assessment. For the outcome-achieving from formal MH curricula, the MH programs of phase-1 (1st and 2nd grades) almost accomplished the PO of communication, patient supporting and professionalism, and considerably accomplished the PO of problem solving and self-development. The MH programs of phase-2 (3rd and 4th grades) accomplished considerably their PO as the competencies of professionalism and problem solving, and partially as communication, patient supporting and self-development. However, as only one program, public health law, was provided for MH program in phase-3 (5th and 6th grades), the extra methods to evaluate their MH outcomes are needed. Many assessing methods can be available for the most MH competencies consisting of the GO of KUSM, and the proper assessing methods for each MH competency should be selected based on programs and learning contexts in MH education. While formal MH curricula of the school variously accomplished the MH competencies of GO according to periodic phases of curricula, it is recommended to enhance the feasibility and effectiveness of evaluation for GO in MH curricula of the school.

Background: The clinical features of pediatric rhabdomyolysis differ from those of the adults with rhabdomyolysis; however, multicenter studies are lacking. This study aimed to investigate the characteristics of pediatric rhabdomyolysis and reveal the risk factors for acute kidney injury (AKI) in such cases. Methods: This retrospective study analyzed the medical records of children and adolescents diagnosed with rhabdomyolysis at 23 hospitals in South Korea between January 2007 and December 2016. Results: Among 880 patients, those aged 3 to 5 years old composed the largest subgroup (19.4%), and all age subgroups were predominantly male. The incidence of AKI was 11.3%. Neurological disorders (53%) and infection (44%) were the most common underlying disorder and cause of rhabdomyolysis, respectively. The median age at diagnosis in the AKI subgroup was older than that in the non-AKI subgroup (12.2 years vs. 8.0 years). There were no significant differences in body mass index, myalgia, dark-colored urine, or the number of causal factors between the two AKI-status subgroups. The multivariate logistic regression model indicated that the following factors were independently associated with AKI: multiorgan failure, presence of an underlying disorder, strong positive urine occult blood, increased aspartate aminotransferase and uric acid levels, and reduced calcium levels. Conclusions Our study revealed characteristic clinical and laboratory features of rhabdomyolysis in a Korean pediatric population and highlighted the risk factors for AKI in these cases. Our findings will contribute to a greater understanding of pediatric rhabdomyolysis and may enable early intervention against rhabdomyolysis-induced AKI.

BACKGROUND: Falls are the most frequent adverse events reported in hospitals. The aim of this study was to investigate the incidence rate and characteristics of falls in patients who used comprehensive nursing care service in National Health Insurance Service Ilsan Hospital. METHODS: Incidence rate of falls was investigated in patients using comprehensive nursing care service, from July 2013 to Jun 2017 and compared with those not using this service. The characteristics and risk factors for falls, and fall-related injuries were obtained. RESULTS: Among the 62,445 patients who used the comprehensive nursing care service for 4 years, total of 672 falls were reported. The incidence rate of falls per 1,000 patients-day was 1.15. The percentage of fall-related injuries was 26.9% and that of major injury was 2.2%. Although the incidence rate of all falls was slightly higher in patients using comprehensive nursing care service than those not using this service, falls-related injuries were not correlated with the implementation of this service. CONCLUSION: The falls could be more frequently detected and reported in comprehensive nursing care service, but there was no difference in fall-related injuries.

Pancreatic cancer has a very poor prognosis. Complete surgical resection remains the only current curative treatment. Locally advanced pancreatic cancer (LAPC) is considered as unresectable because of involvement of celiac and/or mesenteric vessels. The treatment of LAPC is a challenge. Current guidelines suggest systemic therapy. However, the majority of patients will never experience conversion to surgical resection. Thus, in these patients, ablation is an alternative therapy for local control, which causes local destruction while ideally avoiding injury to surrounding healthy tissue. Irreversible electroporation (IRE) is an energy delivery system, effective in ablating tumors by inducing irreversible membrane destruction of cells. IRE demonstrated to be safe in previous studies. However, it is not free from complications, even serious. Here, we reported two cases of the IRE in LAPC patients.
