Objectives To investigate the bidirectional association between sudden sensorineural hearing loss (SSNHL) and open‐angle glaucoma (OAG) over a 12‐year follow‐up period using nationwide, population‐based data. Methods The study was conducted using the National Health Information Database of the National Health Insurance Service (NHIS‐NHID), which covered 3.5 million individuals from 2008 to 2019. In Study 1, we evaluated the effect of OAG on SSNHL, and in Study 2, we evaluated the effect of SSNHL on OAG. Participants of the control group were enrolled through “greedy nearest‐neighbor” 1:1 propensity score matching. Results In Study 1, 26,777 people were included in each group. The hazard ratio (HR) for SSNHL of the OAG group was 1.27 (95% confidence interval [CI], 1.15–1.39). In subgroup analysis, there was significant HR value regarding (old age: 1.17, hyperlipidemia: 1.19). In Study 2, 15,433 people were included in each group. The HR for OAG of the SSNHL group was 1.18 (95% CI, 1.07–1.30). In subgroup analysis, the HRs were significant for old age (2.31), hypertension (1.17), diabetes (1.39), and hyperlipidemia (1.26). Conclusion Over the 12‐year follow‐up, we found a bidirectional association between SSNHL and OAG, suggesting a shared pathogenesis. Level of evidence N/A. Laryngoscope , 133:3169–3177, 2023
Abstract Background Both inflammatory bowel disease (IBD) and ankylosing spondylitis (AS) are inflammatory diseases but there was little previous study that demonstrate the IBD severity and outcome in IBD patients with concomitant AS. Methods Patients’ records were collected from 3 tertiary hospitals (Seoul national university hospital, Seoul national university Bundang hospital, and Seoul metropolitan government Seoul national university Boramae medical center) from October 2004 to June 2021. Patients with IBD and concomitant AS (IBD-AS group) were identified and propensity score matching (PSM) was applied to match the IBD-AS group and IBD patients without AS (only IBD group). Results After PSM, significantly more patients in IBD-AS group had colectomies (p = .017) or were prescribed biologics (p < .001), immunosuppressive agents (p = .021), and steroid (p = .017) than in only IBD group. The number of patients treated with biologics (p < .001) or immunosuppressive agents (p = .032) were significantly greater in UC-AS group than in only UC group. There was no significant difference in outcomes between only CD group and CD-AS group. In logistic regression analyses, identified that concomitant AS was a significant factor associated with biologics treatment in patients with IBD. Kaplan-Meier analyses demonstrated that there was a significant difference in the probability of starting biologics treatment between IBD patients with and without concomitant AS (p = 0.002). In UC patients, the probability of starting biologics was also significantly different according to concomitance of AS (p < 0.001). Concomitant AS was a risk factor for predicting biologics treatment in patients with UC in Cox regression analysis after adjustment UC (adjusted hazard ratio, 6.296; confidence interval, 2.243 to 17.668; p < 0.001) Conclusion Patients with IBD-AS group were more likely to have a higher severity than in only IBD group. The current study result can help IBD specialists understand and treat patients with IBD and concomitant AS better.
Purpose: To analyze the clinical characteristics of patients with acute acquired comitant esotropia, evaluate the outcomes of augmented medial rectus muscle recession, and propose indicators for determining the appropriate surgical dosage.Methods: Data of patients with acute acquired esotropia who underwent medial rectus recession between 2016 and 2022 were retrospectively analyzed. The amount of medial rectus muscle recession was 1-2 mm greater than for other types of esotropia. Surgical success was assessed by reference to the angle of deviation and diplopia status 6 months after surgery. We investigated the amount of additional recession required for favorable surgical outcomes, the characteristics of groups that required augmentation, and changes in surgical amount according to the deviation angle.Results: A total of 38 patients were included; the average refractive error was -3.79 ± 3.11 diopters (D). Patient age at the time of surgery was 25.6 ± 18.2 years and the preoperative deviation angle was 38.1 ± 11.5 prism diopters (PD). The amount of medial rectus muscle recession was 6.25 ± 1.4 mm, i.e., 1.2 ± 1.0 mm greater than during other surgeries. The average augmentation was 24.1 ± 18.8%. The motor surgical success rate was 92.1% and the sensory success rate was 97.4%. The required augmentation was 26.9% for those with angles of deviation < 30 PD, 25.5% for patients with angles between 30 and 40 PD, and 20.0% for those with angles > 40 PD. Patients who required augmentation > 25% were older, and the surgical effect was greater as the angle of deviation increased.Conclusions: To ensure successful surgical outcomes of patients with acute acquired comitant esotropia, it is essential to increase the amount of medial rectus recession compared to that during other surgeries; the average augmentation was 24% in this study.

Background: Optic neuritis, an inflammation of the optic nerve, commonly occurs in young adults and often associated with demyelinating diseases, such as multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), myelin oligodendrocyte glycoprotein antibody disease (MOGAD), and acute disseminated encephalomyelitis. These conditions frequently exhibit recurrent and progressive inflammatory episodes, significantly impacting prognosis. Differentiating these diseases is crucial because of their distinct clinical presentations, treatment responses, and outcomes. Recent advancements in biomarkers, such as aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) antibodies, have enhanced diagnostic precision.Current Concepts: The introduction of AQP4 and MOG-immunoglobulin G (IgG) antibody testing has revolutionized diagnostic approaches for optic neuritis. AQP4-IgG is a highly specific marker for NMOSD, facilitating early diagnosis, essential for timely intervention and improved patient outcomes. MOG-IgG has been identified as a distinct marker for MOGAD, differentiating it from MS and NMOSD. These biomarkers aid in understanding the pathophysiological mechanisms underlying optic neuritis and in tailoring individualized treatment strategies.Discussion and Conclusion: The use of AQP4 and MOG-IgG antibodies represents a significant leap forward in managing optic neuritis. These biomarkers not only assist in accurate diagnosis but also provide insights into disease prognosis and therapeutic responses. Future studies should focus on the detailed clinical and pathological characteristics associated with these biomarkers to refine treatment protocols further and enhance patient care. Continued advancements in biomarker research hold promise for the development of new therapeutic avenues and the potential for improved long-term outcomes in patients with optic neuritis.
Abstract Background Endoscopy plays an essential role in the diagnosis and management of inflammatory bowel disease (IBD). Although the interval of endoscopy is important to assess the disease status of IBD, there are limited research date on the real-world use of endoscopy in patients with IBD. Therefore we aimed to evaluate the current status of lower gastrointestinal (GI) endoscopy in IBD patients. Methods We conducted a nationwide, retrospective, observational cohort study using the Korean national health insurance claims data. The endoscopy cohort with IBD was defined as an IBD population who underwent at least one colonoscopy or sigmoidoscopy between 2010 and 2019. We evaluated the annual number of lower GI endoscopy use, including colonoscopy and sigmoidoscopy in the IBD prevalent patients. In addition, we analyzed the trend of endoscopy use stratified by year after diagnosis in the patients with newly diagnosed IBD between 2010 and 2017 and the logistic regression modeling was used to estimate odds ratios and 95% confidence intervals for endoscopy, compared with never having had endoscopy, by demographic factor and therapeutic medications used for IBD. Results The analysis included 54,634 IBD patients (34,633 male and 20,001 female), among whom 24,577 (44.94%) underwent lower GI endoscopy. During a mean follow-up of 4 years, endoscopy was performed the most in the first year after diagnosis, and it showed a decreasing trend after that. Multivariate analysis showed that IBD patients with biologics and small molecules received more endoscopy than patients without the medication (hazard ratio [HR] 27.671, 95% confidence interval [CI] 11.296–67.783). In Crohn’s disease, increased number of biologics and small molecules correlated with increased number of endoscopy (HR 1.049, 95% CI 0.981–1.122 for single biologic; HR 2.343, 95% CI 1.726–3.182 for two or more biologics). In ulcerative colitis, however, only the use of biologics and small molecules, not the number of medication, correlated with increased number of endoscopy (HR 23.26, 95% CI 9.489–57.02). IBD patients with steroid (HR 1.562, 95% CI 1.509–1.61) and 5-aminosalicylic acid (HR 1.622, 95% CI 1.537–1.711) were received more endoscopy than patients without the medication. Conclusion Endoscopy was performed more frequently in the first one year after diagnosis with IBD. Also, this study demonstrated significant association between the use of endoscopy and the biologics/small molecules administered for IBD.
Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by relapsing and remitting episodes. Although AD is well-known for its association with other allergic conditions, its relationship with Meniere's disease has not been thoroughly investigated. This study aimed to explore the potential correlation between AD and Meniere's disease.
