Objectives: Tegoprazan, a novel potassium-competitive acid blocker with rapid and effective antisecretory activity, was approved for the treatment of Helicobacter pylori infections in Korea in March 2020. However, real-world data regarding tegoprazan-based therapies are scarce. We compared the efficacies of tegoprazan- and lansoprazole-based triple therapies (TTs). Methods: Between March 2020 and February 2023, this study enrolled patients diagnosed with H. pylori infections who were prescribed either 14-day tegoprazan- or lansoprazole-based TTs as first-line treatments. Their medical records were retrospectively reviewed to compare H. pylori eradication rates and the rates of patient adherence to the recommended therapy. Results: A total of 670 patients diagnosed with H. pylori infections were prescribed 14-day TT regimens between March 2020 and February 2023 at Ilsan Paik Hospital (Goyang, Korea). Of those enrolled in the study, 64 received tegoprazan-based TT and 295 received lansoprazole-based TT as their first-line treatment. The H. pylori eradication rates for tegoprazan- and lansoprazole-based TTs were 76.6% and 75.6%, respectively, in the intent-to-treat population; the rates were 88.9% and 88.4%, respectively, in the per-protocol population (non-inferiority test, p=0.03 and p=0.01 in the respective populations). No significant differences were observed between the two groups with regards to treatment adherence rates (84.4% vs. 85.1%, p=0.78). Conclusions As a first-line treatment for H. pylori eradication, 14-day tegoprazan-based TT demonstrated non-inferior efficacy compared with 14-day lansoprazole-based TT.

Background: and Purpose Moderate-intensity statin plus ezetimibe versus high-intensity statin alone may provide a greater low-density lipoprotein cholesterol (LDL-C) reduction in patients with recent ischemic stroke. Methods: This randomized, open-label, controlled trial assigned patients with recent ischemic stroke <90 days to rosuvastatin/ezetimibe 10/10 mg once daily (ROS10/EZT10) or to rosuvastatin 20 mg once daily (ROS20). The primary endpoint was LDL-C reduction ≥50% from baseline at 90 days. Key secondary endpoints were LDL-C <70 mg/dL and multiple lipid goal achievement, and composite of major vascular events. Results: Of 584 randomized, 530 were included in the modified intention-to-treat analysis. The baseline LDL-C level was 130.2±34.7 mg/dL in the ROS10/EZT10 group and 131.0±33.9 mg/dL in the ROS20 group. The primary endpoint was achieved in 198 patients (72.5%) in the ROS10/EZT10 group and 148 (57.6%) in the ROS20 group (odds ratio [95% confidence interval], 1.944 [1.352–2.795]; P= 0.0003). LDL-C level <70 mg/dL was achieved in 80.2% and 65.4% in the ROS10/EZT10 and ROS20 groups (P=0.0001). Multiple lipid goal achievement rate was 71.1% and 53.7% in the ROS10/EZT10 and ROS20 groups (P<0.0001). Major vascular events occurred in 1 patient in the ROS10/EZT10 group and 9 in the ROS20 group (P=0.0091). The adverse event rates did not differ between the two groups. Conclusion Moderate-intensity rosuvastatin plus ezetimibe was superior to high-intensity rosuvastatin alone for intensive LDL-C reduction in patients with recent ischemic stroke. With the combination therapy, more than 70% of patients achieved LDL-C reduction ≥50% and 80% had an LDL-C <70 mg/dL at 90 days.

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disease. IgG4-RD can affect any organ system, including the pancreas, bile ducts, salivary glands, mesentery, and retroperitoneum. On the other hand, small intestine involvement is extremely rare. This paper describes a case of IgG4-RD involving the small bowel, particularly at the distal ileum. An 81-year-old female was admitted to the authors’ hospital complaining of abdominal pain, dyspepsia, and hematochezia. The laboratory tests, including tumor markers and IgG4, were within normal limits. A colonoscopy did not show any abnormal findings. Abdominal computed tomography revealed segmental aneurysmal dilatation and wall thickening at the distal ileum, suggesting malignant conditions, such as small bowel lymphoma. The patient underwent an exploratory laparoscopy and ileocecectomy to differentiate a malignancy. A histopathology examination revealed dense lymphoplasmacytic infiltration, storiform fibrosis, and IgG4-positive plasma cells (>50 per high power field). The patient was finally diagnosed with IgG4-RD. The patient was followed up in the outpatient clinic for five years without recurrence. This paper suggests that a radical resection without maintenance therapy can be a treatment option, particularly when the IgG4-RD manifests as a localized gastrointestinal tract lesion.

Objective: To translate the 22-item Longer-term Unmet Needs after Stroke (LUNS) questionnaire, validate it in the Korean stroke population, and assess the reliability of face-to-face and telephone surveys. Methods: Sixty-six adult patients with stroke from Seoul National University Bundang Hospital and Kangwon National University Hospital were involved in the validation. Participants were interviewed twice using the LUNS Korean version: first, a face-to-face survey for validation, and second, a telephone survey for test-retest reliability. Participants completed the Frenchay Activities Index (FAI) and Short Form 12 (SF-12) Mental and Physical Component Summary (MCS and PCS) scores at the first interview. For concurrent validity, the differences in health status (FAI, SF-12 MCS and PCS) between the groups that reported unmet needs and those that did not were analyzed for each item. Cohen’s kappa and percentage of agreement between the first and second administrations were calculated for each item to determine the test-retest reliability. Results: The average age of the participants was 61.2±12.8 years and 74.2% were male. Fifty-seven patients were involved in the second interview. Depending on the unmet needs, SF-12 MCS, PCS, and FAI were significantly different in 12 of 22 items. In the test-retest reliability test, 12 items had a kappa of 0.6 or higher, and two had a kappa of <0.4. Conclusion The LUNS instrument into Korean (LUNS-K) is a reliable and valid instrument for assessing unmet health needs in patients with stroke. In addition, telephone surveys can be considered reliable.

Background: Patients with Parkinson’s disease (PD) experience both motor and non-motor symptoms, including dysphagia. Although PD is closely associated with dysphagia, the prevalence or risk of dysphagia in PD is unclear, especially in Asian countries. Methods: The prevalence of PD and dysphagia with PD in the general population was analyzed using the Korean National Health Insurance Service (NHIS) database. The prevalence per 100,000 persons of PD and dysphagia with PD from 2006 to 2015 was analyzed in the general population aged ≥ 40 years. Patients newly diagnosed with PD between 2010 and 2015 were compared with those without PD. Results: The prevalence of PD and dysphagia in patients with PD increased continuously during the study period and was highest in the ninth decade of life. The percentage of patients with dysphagia in patients with PD increased with age. Patients with PD showed an adjusted hazard ratio of 3.132 (2.955–3.320) for dysphagia compared to those without PD. Conclusion This nationwide study showed increasing trends in the prevalence of PD and dysphagia among patients with PD in Korea between 2006 and 2015. The risk of dysphagia was three times higher in patients with PD than that in those without PD, highlighting the importance of providing particular attention.

A perilymphatic fistula (PLF) is an abnormal leakage of the perilymph from the inner ear into the middle ear. A PLF may be trauma-induced or may occur with unknown causes. PLF repair should be considered when patients present with sudden or progressive sensorineural hearing loss with positional nystagmus. Although the leakage of perilymph is not always found during the exploration surgery, both hearing loss and dizziness tend to improve immediately after PLF repair. However, about 24% of patients who underwent PLF repair reportedly have experienced recurrent vestibular symptoms, suggesting the possibility of PLF recurrence or other vertigo causes. In this PLF patient, dizziness completely subsided after the PLF repair. However, several months later, the disabling paroxysmal positional vertigo developed, which was diagnosed as benign paroxysmal positional vertigo. Reported herein, with a review of the relevant literature, is a case of paroxysmal positional vertigo several months after PLF repair, where successful vertigo subsidence was finally achieved.

Nasal valve collapse is one of the causes of nasal obstruction and must be considered in patients with nasal obstruction. There are several surgical procedures available to treat nasal valve collapse. Spreader grafts can be used in the treatment of nasal valve collapse by widening the internal nasal valve angle and maintaining the widened angle. However, this procedure requires sufficient amount of cartilage harvested from the nasal septum. Especially, in cases of secondary rhinoplasty or some primary nasal surgery with thin septal cartilage, it is difficult to harvest an appropriate amount of cartilage from the septum. Here, we describe an effective technique for using septal cartilage and TnR Nasal Mesh® (T&R Biofab Co., Ltd) for spreader grafts with appropriate thickness in nasal valve collapse.
