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.

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: Among various emerging catheter-based treatments for severe tricuspid regurgitation (TR), the spacer device can reduce the regurgitation orifice without manipulating the valve leaflet. However, its clinical application has been hampered by traumatic anchoring to the myocardium and the coaxial alignment of the balloon resulting in insufficient TR reduction. This study aimed to evaluate the early-stage safety, technical feasibility, and preliminary efficacy of the novel atraumatic vertical spacer in patients with isolated severe TR. Methods: All procedures were guided by fluoroscopy and transthoracic echocardiography.The maximum device placement time with an inflated balloon was 24 hours. Changes in the amount of TR, right ventricular function, and patient hemodynamics were measured during balloon deployment. Results: A total of 7 patients (median age 74), underwent successful device implantation without procedure-related complications. During balloon inflation (median 25 minutes), there were no symptoms or signs indicative of TR intolerance. TR was reduced by 1 grade or greater in all patients, with 2 patients exhibiting a reduction of 3 grades, from torrential TR to a moderate degree. Mild TR after balloon inflation was achieved in 3 patients with baseline severe TR. The TR reduction observed during initial balloon deployment was sustained during the subsequent balloon maintenance period. Conclusions The Pivot-balloon procedure was safe, technically feasible, and effective in reducing TR in patients with severe TR. No periprocedural complications or adverse cardiovascular events were reported during device placement with TR reduction observed in all patients. However, longer-term follow-up is needed to confirm safety and treatment effect.

Background: We hypothesized that intranasal combination of dexmedetomidine (2 μg/kg) and ketamine (3 mg/kg) (IN DEXKET) improves the success rate of sedation in pediatric patients compared with chloral hydrate (CH; 50 mg/kg). Methods: This prospective, two-center, single-blinded, randomized controlled trial involved 136 pediatric patients (aged < 7 years) requiring procedural sedation. The participants were randomized to receive CH or IN DEXKET via a mucosal atomizer device. The primary outcome was the success rate of sedation (Pediatric Sedation State Scale, scores 1–3) within 15 min. The secondary outcomes included sedation failure at 30 min and overall complications of first-attempt sedation. Results: After excluding eight patients, 128 were included (CH = 66, IN DEXKET = 62). IN DEXKET showed a similar sedation success rate (75.8% [47/62] vs. 66.7% [44/66]; P = 0.330) but a lower complication rate (3.2% [2/62] vs. 16.7% [11/66]; P = 0.017) than CH. In the subgroup analysis for patients aged < 1 year, IN DEXKET showed a reduced complication rate than CH (2.6% [1/38] vs. 22.9% [8/35]; P = 0.012). In the subgroup analysis of children aged 1–7 years, IN DEXKET showed a higher sedation success rate within 15 min (79.2% [19/24] vs. 51.6% [16/31]; P = 0.049) and a lower sedation failure after 30 min (0% vs. 29.0% [9/31]; P = 0.003) than CH. Conclusions The intranasal combination of dexmedetomidine (2 μg/kg) and ketamine (3 mg/kg) is a safe and effective alternative to CH (50 mg/kg) for sedation in pediatric patients aged < 7 years.

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.

It is difficult to determine a cause of bile duct stricture and dilatation. Eosinophilic cholangitis, a rare benign condition, may be one cause of bile duct stricture and dilatation. It can be evaluated using various methods of histopathology, radiographs, endoscopy, and hematologic findings. Treatment generally involves steroid therapy which can lead to improvement. This case report will discuss eosinophilic cholangitis, emphasizing that while it can easily be overlooked but should be considered in differential diagnoses.
