Korea’s medical accident compensation system is a vital national initiative designed to create a stable environment for both mothers and healthcare professionals. This article examines how Korea's neighboring countries, Taiwan and Japan, operate their obstetric compensation systems to draw lessons and implications for Korea's approach.Current Concepts: Korea's medical malpractice compensation system is fully funded by the government, and the amount is determined by the Compensation Review Committee, which considers the type of accident and, in cases of cerebral palsy, the degree of impairment, with awards reaching up to 30 million won. Japan experienced severe declines in birth rates, a shortage of obstetricians, and the closure of maternity hospitals due to increasing medical litigation. In response, the government ,in 2009, introduced a no-fault obstetric compensation system that covers cerebral palsy cases regardless of negligence. Taiwan faced a surge in medical disputes, particularly in obstetrics and gynecology, with maternal lawsuits comprising 14% of all cases. In 2016, the government introduced the Childbirth Accident Emergency Relief Act, achieving a 93.9% compensation approval rate Discussion and Conclusion: Observing these challenges, young doctors are increasingly dissuaded from pursuing careers in obstetrics and gynecology doctor, thereby accelerating the decline of maternity care services. To maintain a stable medical environment, compensation amounts should be adjusted to reflect actual medical costs, and reimbursement rates for obstetric procedures should be re-evaluated. Drawing on the successful implementations in Japan and Taiwan, South Korea must establish a sustainable and protective obstetric care system at the national level.

Objective: The Daegu region experienced the first wave of the pandemic at the beginning of the coronavirus disease 2019 (COVID-19) outbreak in Korea. Other non-COVID-19-related treatments during a community outbreak, such as cardiovascular diseases, were expected to impact emergency departments. In acute myocardial infarctions, time is an important factor affecting the patient outcome. This study examined how community COVID-19 outbreak affected STsegment elevated myocardial infarction (STEMI) care in emergency departments. Methods: A retrospective analysis was performed on patients visiting five emergency departments in the Daegu area who were diagnosed with STEMI from February 18 to April 17 each year from 2018 to 2020. The demographic characteristics, prehospital variables, in-hospital time variables, and treatment results were collected. The cases were divided into the pre-COVID period and the COVID period for comparison. Results: The study included 254 patients (194 pre-COVID, 60 during COVID). The symptom-to-door time did not differ. Although the door-to-first doctor time was shortened (4 min vs. 2 min, P=0.01), the rate of coronary angiogram along with the door-to-angiogram time and the door-to-balloon time did not change. The length of stay in the emergency department was delayed during COVID-19 (median, 136 min vs. 404 min; P<0.01). The in-hospital length of stay and mortality were similar in both groups. Conclusion The time to treat STEMI was not delayed significantly during the first wave of the COVID-19 outbreak in the Daegu area compared with the pre-pandemic period. Mortality did not change. The length of stay was elongated significantly in the emergency department but not in the hospital.

Background and Objectives: Outcomes of deferring percutaneous coronary intervention (PCI) without invasive physiologic assessment for intermediate coronary lesions is uncertain.We sought to compare long-term outcomes between medical treatment and PCI of intermediate lesions without invasive physiologic assessment. Methods: A total of 899 patients with intermediate coronary lesions between 50% and 70% diameter-stenosis were randomized to the conservative group (n=449) or the aggressive group (n=450). For intermediate lesions, PCI was performed in the aggressive group, but was deferred in the conservative group. The primary endpoint was major adverse cardiac events (MACE, a composite of all-cause death, myocardial infarction [MI], or ischemia-driven any revascularization) at 3 years. Results: The number of treated lesions per patient was 0.8±0.9 in the conservative group and 1.7±0.9 in the aggressive group (p=0.001). At 3 years, the conservative group had a significantly higher incidence of MACE than the aggressive group (13.8% vs. 9.3%; hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.00–2.21; p=0.049), mainly driven by revascularization of target intermediate lesion (6.5% vs. 1.1%; HR, 5.69; 95% CI, 2.20–14.73;p<0.001). Between 1 and 3 years after the index procedure, compared to the aggressive group, the conservative group had significantly higher incidence of cardiac death or MI (3.2% vs.0.7%; HR, 4.34; 95% CI, 1.24–15.22; p=0.022) and ischemia-driven any revascularization. Conclusions For intermediate lesions, medical therapy alone, guided only by angiography, was associated with a higher risk of MACE at 3 years compared with performing PCI, mainly due to increased revascularization.

Background: The oxygen reserve index (ORi) noninvasively measures oxygen levels within the mild hyperoxia range. To evaluate whether a degree of increase in the ORi during preoxygenation for general anesthesia is associated with the occurrence of postoperative pulmonary complications (PPCs). Methods: We enrolled 154 patients who underwent preoperative pulmonary function tests and were scheduled for elective surgery under general anesthesia. We aimed to measure the increase in ORi during preoxygenation before general anesthesia and analyze its association with PPCs. Results: PPCs occurred in 76 (49%) participants. Multivariate logistic regression analysis revealed that the three-minute preoxygenation ORi was significantly associated with PPCs (Odds ratio [OR]: 0.02, 95% CI [0.00–0.16], P < 0.001). The areas under the curve (AUC [95% CI]) in the receiver operating characteristic curve analysis for the three-minute preoxygenation ORi for PPCs were 0.64 (0.55–0.73). After a subgroup analysis, multivariate logistic regression showed that the three-minute preoxygenation ORi was significantly associated with PPCs among patients who underwent thoracic surgery (OR: 0.01, 95% CI [0.00–0.19], P = 0.006). The AUC of the three-minute preoxygenation ORi for PPCs was 0.72 (0.57–0.86) in patients who underwent thoracic surgery. Conclusions A low ORi measured after 3 min of preoxygenation for general anesthesia was associated with an increased risk of PPCs, including those undergoing thoracic surgery. This study demonstrated the potential of ORi, measured after oxygen administration, as a tool for evaluating lung function that complements traditional lung function tests and scoring systems.

Background: Syphilis, an infectious and chronic disease primarily transmitted through sexual contact, is caused by the spirochete bacterium Treponema pallidum. Although the introduction of penicillin has significantly reduced its incidence, syphilis continues to have a substantial impact on public health. Objective: The purpose of this study was to investigate trends in syphilis and to analyze its epidemiologic, clinical, and serologic characteristics. Methods: We retrospectively reviewed the medical records of 330 patients who tested positive for the Venereal Disease Research Laboratory (VDRL) test, including 192 patients who received a diagnosis of syphilis and who visited the Dermatology Department of Gachon University Gil Medical Center between 2000 and 2023. Statistical analyses were performed to evaluate trends in syphilis incidence and related variable factors, such as sex, age, and serological results. Results: The average age of the 192 syphilis patients was 34.18±15.81 years, with a male-to-female ratio of 1:1.2. The most prevalent age group was 20∼29 years, comprising 71 patients (37.0%). Over time, the incidence of syphilis demonstrated a decreasing trend (p＜0.001). A total of 105 patients (54.7%) were diagnosed with symptomatic syphilis, with a male-to-female ratio of 1.5:1. The proportion of symptomatic syphilis patients tended to decrease with increasing age (p＜0.05). Maculopapular syphilis was the most frequently observed presentation in secondary syphilis (36.2%). The proportion of symptomatic syphilis patients significantly increased with higher VDRL titers (p＜0.001). Conclusion The incidence of syphilis has shown a consistent decline over the past two decades. However, the relatively higher prevalence among younger age groups indicates the need for continued public health efforts.

Regorafenib is an oral multikinase inhibitor used to treat advanced solid tumors, including hepatocellular carcinoma (HCC), gastrointestinal stromal tumors, and colorectal cancer. Adverse dermatological reactions are common after regorafenib treatment. The most frequent cutaneous adverse reaction is hand-foot skin reaction (HFSR). Compared to HFSR, reports on adverse reactions on the scrotum associated with regorafenib are limited. Only a few cases of adverse reactions on the scrotum associated with HFSR have been reported. We present the case of a 55-year-old male patient with a 1-year history of scrotal dermatitis and HFSR, who had been undergoing treatment for HCC.One year after administration of oral regorafenib (160 mg/d), multiple vesicles, pustules, desquamation, and hyperkeratosis developed on both hands and feet, accompanied by scaly erythematous plaques around the scrotum.The lesions improved after two weeks of treatment with topical and systemic steroids. Herein, we report a rare case of scrotal dermatitis associated with regorafenib-induced HFSR.

Background: Tobacco use has been the leading cause of disease and death in South Korea. Early detection of tobacco use and evidence-based interventions play pivotal roles in facilitating tobacco cessation. Methods: In accordance with the earlier iterations of the Lifetime Health Maintenance Program (2009) and recent recommendations from the United States Preventive Services Task Force (USPSTF; 2021), two themes were chosen for investigation: the identification of and intervention for tobacco use. The USPSTF recommendations were formulated by conducting an overview of reviews. In this study, literature searches and quality assessments of reviews were conducted. Results: The findings highlighted the efficacy of physician-led identification and advising in promoting tobacco cessation, with robust evidence supporting the implementation of behavioral and pharmacological interventions. These interventions significantly increased the likelihood of successful cessation compared with usual care. Digital interventions, such as internet- or mobile-based interventions, showed additive effects for quitting. Conclusion Identification and targeted interventions are essential for tobacco cessation. By leveraging evidencebased strategies and enhancing access to resources, healthcare providers can empower individuals to achieve successful tobacco cessation and improve overall health outcomes.

Ketone bodies produced by sodium-glucose cotransporter 2 (SGLT2) inhibitors can be advantageous, providing an efficient and stable energy source for the brain and muscles. However, in patients with diabetes, ketogenesis induced by SGLT2 inhibitors may be harmful, potentially resulting in severe diabetic ketoacidosis (DKA). During fasting, ketone body production serves as an alternative and efficient energy source for the brain by utilizing stored fat, promoting mental clarity, and reducing dependence on glucose. The concurrent use of SGLT2 inhibitors during perioperative fasting may further elevate the risk of euglycemic DKA. We describe a case of DKA that occurred during perioperative fasting in a patient receiving empagliflozin, an SGLT2 inhibitor. This case underscores the importance of recognizing the potential risk of DKA in patients with diabetes using SGLT2 inhibitors during perioperative fasting.

Purpose: Ultrasound-guided nerve hydrodissection has emerged as a potential non-surgical treatment for carpal tunnel syndrome (CTS). The objective of this research was to offer suggestions for optimizing injectables utilized in hydrodissection for the treatment of CTS through a systematic review and network meta-analysis. Materials and Methods: PubMed, MEDLINE, EMBASE, Cochrane, Scopus, and Web of Science were searched through April 25, 2024. Effect sizes were quantified using standard mean differences within a random-effects model. Effectiveness ranking for each treatment was expressed as the surface under the cumulative ranking curve (SUCRA). Results: Nine studies with 458 patients with CTS were included. According to SUCRA, 5% dextrose (DW) was the most effective option for the Boston Carpal Tunnel Questionnaire (BCTQ) function at 99.9, 89.8, and 88.8 at 4, 12, and 24 weeks, respectively; for BCTQ symptoms, 5% DW was the most effective option at 99.9 at 4 weeks and platelet-rich plasma at 95.7 and 93.9 at 12 and 24 weeks, respectively. In terms of both BCTQ symptoms and BCTQ function, the 5 cc injection was the most effective, with SUCRA values of 99.5 for both categories. However, the effectiveness of the electrodiagnostic assessment and ultrasound variables was dependent on the type and dose of medication. Conclusion Administration of 5% DW showed better results in terms of initial symptom relief and long-term functional recovery compared to other agents, while platelet-rich plasma showed greater long-term symptom improvement; an injection dose of 5 cc showed the greatest benefit. However, additional research is required to establish precise protocols based on disease severity.

Helicobacter pylori causes gastric cancer and peptic ulcers, and eradication therapy can reduce the incidence of cancer in high-risk groups. In Korea, discrepancies between the reimbursement criteria and clinical guidelines create clinical challenges. This study investigated the perceptions and practices of experts regarding H. pylori testing during upper gastrointestinal endoscopy and any subsequent eradication therapy. An anonymous 8-question survey was conducted among 51 experts attending the 2024 Korean College of Helicobacter and Upper Gastrointestinal Research Summer Workshop. Only 2% of the experts tested all patients. Testing was performed in 54% of patients with a family history of gastric cancer, 32% of those with atrophic gastritis, 42% of those with dyspeptic symptoms, and 62% of those with iron-deficiency anemia. Among patients with suspected infections (based on endoscopic findings) and eligible for selective reimbursement, 82% underwent H. pylori testing. Age did not influence testing decisions for 60% of the experts, and 57% considered factors other than age when deciding on eradication therapy. The practices of the experts varied depending on the patient’s clinical condition and economic burden. Aligning clinical guidelines with the reimbursement criteria is necessary to reduce confusion and ensure appropriate patient care.
