Background and Objectives: Hearing loss significantly affects communication, psychosocial well-being, and quality of life. This study analyzes the National Health Insurance Service database to assess the trends and characteristics of hearing loss in South Korea from 2010 to 2020.Subjects and Method The database encompasses 97% of the Korean population, providing comprehensive data on medical history, prescriptions, and health examinations. The analysis used the World Health Organization’s ICD-10 definitions to categorize hearing loss types and examine their prevalence and incidence across various demographics over 11 years. Results: There was an overall annual increase of 4.62% in diagnosed cases of hearing loss, with the most significant rise among the elderly. The rate of increase accelerated from 3.32% between 2010 and 2014 to 6.49% between 2014 and 2020, corresponding with the improved hearing aid access facilitated by policy changes. Women showed a slightly higher increase than men. The data also indicated a consistent rise in abnormal hearing test results during health examinations, especially in older adults. Conclusion The study highlights an increasing trend in hearing loss diagnoses, driven by an aging population and enhanced detection facilitated by policy changes. These findings emphasize the need for continuous monitoring and targeted health policies to manage hearing loss effectively, offering valuable insights for global health management and policy development.

Background and Objectives: This study aims to analyze trends in hearing disability and the use of hearing rehabilitation devices (hearing aids and cochlear implants) in South Korea over the past 11 years (2010-2020) using data from the National Health Insurance Service (NHIS).Subjects and Method Data were extracted from the NHIS database, covering approximately 97% of the South Korean population. Patients diagnosed with hearing loss were classified using ICD-10 codes. The data were analyzed to determine trends in hearing disability, hearing aid prescriptions, and cochlear implant usage by age, gender, and types and causes of hearing loss. Results: The number of hearing disability patients increased from 170900 in 2010 to 362738 in 2020, with an annual growth rate of 7.95%. The highest increase was observed in the ≥60 age group, with an annual growth rate of 11.04%. Hearing aid prescriptions rose from 4966 in 2010 to 11974 in 2020, showing a 10.45% annual increase. Females showed a higher growth rate in both hearing disability and hearing aid prescriptions compared to males. Cochlear implant prescriptions also increased, particularly among older adults. Conclusion The study highlights a significant rise in hearing disability and the use of hearing aids and cochlear implants in South Korea, especially among the elderly. The findings underscore the importance of early diagnosis and intervention for hearing loss and the need for policy improvements to enhance accessibility and affordability of hearing rehabilitation services. Additional strategies are needed to ensure appropriate hearing rehabilitation for those not yet receiving adequate care.

Objectives: This study aimed to evaluate the effectiveness of a multidisciplinary pulmonary rehabilitation program at Ewha Womans University Mokdong Hospital, Korea that was designed to augment respiratory function, promote patient recovery, and improve discharge outcomes.

Methods: This study was conducted as part of quality improvement activities from March to August 2023. A multidisciplinary pulmonary rehabilitation team was established, comprising specialists in rehabilitation medicine, pulmonology, and thoracic surgery, as well as physical and occupational therapists, and the nutrition team. We developed a comprehensive rehabilitation program that included stretching, strengthening exercises, aerobic training, and respiratory retraining, supplemented by individualized treatments such as bedside and ambulatory physical therapy. Evaluations before and after rehabilitation were performed using the Modified Medical Research Council Dyspnea Scale and the Chronic Obstructive Pulmonary Disease Assessment Test. The primary indicators of success were an increase of over 10% in pulmonary rehabilitation consultations and an improvement in discharge-to-home rates.

Results: The total number of pulmonary rehabilitation cases rose by 79.16%, from 24 to 43, while consultations saw a 21.15% increase, from 52 to 63. Of the 63 pulmonary rehabilitation cases, 32 (50.8%) were transferred to other hospitals, 25 (39.7%) were discharged home, and 6 (9.5%) remained hospitalized.

Conclusion: The study demonstrated the effectiveness of a multidisciplinary pulmonary rehabilitation approach in improving program participation and achieving meaningful discharge outcomes. These findings underscore the potential for expanding multidisciplinary efforts and highlight the need for further studies to increase discharge-to-home rates and evaluate the long-term impacts of such programs.

Purpose: Adjuvant treatment for craniopharyngioma after surgery is controversial. Adjuvant external beam radiation therapy (EBRT) can increase the risk of long-term sequelae. Stereotactic radiosurgery (SRS) is used to reduce treatment-related toxicity.In this study, we compared the treatment outcomes and toxicities of adjuvant therapies for craniopharyngioma. Materials and Methods: We analyzed patients who underwent craniopharyngioma tumor removal between 2000 and 2017. Of the 153 patients, 27 and 20 received adjuvant fractionated EBRT and SRS, respectively. We compared the local control (LC), progression-free survival (PFS), and overall survival between groups that received adjuvant fractionated EBRT, SRS, and surveillance. Results: The median follow-up period was 77.7 months. For SRS and surveillance, the 10-year LC was 57.2% and 57.4%, respectively. No local progression was observed after adjuvant fractionated EBRT. One patient in the adjuvant fractionated EBRT group died owing to glioma 94 months after receiving radiotherapy (10-year PFS: 80%). The 10-year PFS was 43.6% and 50.7% in the SRS and surveillance groups, respectively. The treatment outcomes significantly differed according to adjuvant treatment in nongross total resection (GTR) patients. Additional treatment-related toxicity was comparable in the adjuvant fractionated EBRT and other groups. Conclusion Adjuvant fractionated EBRT could be effective in controlling local failure, especially in patients with non-GTR, while maintaining acceptable treatment-related toxicity.

Multidirectional joint instability is a condition where laxity occurs in two or more directions. This condition typically arises congenitally or because of hypermobility or repetitive, excessive physical activity. It can also occur from chronic damage to the joint capsule and multiple ligaments, causing a breakdown in stability. Despite the numerous studies conducted on multidirectional instability of the shoulder, there is a lack of published research on multidirectional instability of the ankle. This paper reports the case of a male patient in his early 30s, engaged in high-demand physical activity, who presented with simultaneous medial and lateral ankle instability. The patient underwent a combination of procedures, including an anterior talofibular ligament reconstruction with suture tape, deltoid ligament reattachment with suture anchors, anteroinferior tibiofibular ligament reconstruction with suture tape, and syndesmotic screw fixation with Tightrope insertion. The patient was followed up for one year postoperatively. This paper reports the clinical outcomes with a review of the relevant literature.

Background: and Purpose This study evaluated the diagnostic utility of an anti-signal-recognition particle 54 (anti-SRP54) antibody-based enzyme-linked immunosorbent assay (ELISA) as well as the clinical, serological, and pathological characteristics of patients with SRP immune-mediated necrotizing myopathy (IMNM). Methods: We evaluated 87 patients with idiopathic inflammatory myopathy and 107 healthy participants between January 2002 and December 2023. The sensitivity and specificity of the ELISA for anti-SRP54 antibodies were assessed, and the clinical profiles of patients with antiSRP54 antibodies were determined. Results: The ELISA for anti-SRP54 antibodies had a sensitivity and specificity of 88% and 99%, respectively, along with a test–retest reliability of 0.92 (p<0.001). The 32 patients diagnosed with anti-SRP IMNM using a line-blot immunoassay included 28 (88%) who tested positive for anti-SRP54 antibodies using the ELISA, comprising 12 (43%) males and 16 (57%) females whose median ages at symptom onset and diagnosis were 43.0 years and 43.5 years, respectively. Symptoms included proximal muscle weakness in all 28 (100%) patients, neck weakness in 9 (32%), myalgia in 15 (54%), dysphagia in 5 (18%), dyspnea in 4 (14%), dysarthria in 2 (7%), interstitial lung disease in 2 (7%), and myocarditis in 2 (7%). The median serum creatine kinase (CK) level was 7,261 U/L (interquartile range: 5,086–10,007 U/L), and the median anti-SRP54 antibody level was 2.0 U/mL (interquartile range: 1.0–5.6 U/mL). The serum CK level was significantly higher in patients with coexisting anti-Ro-52 antibodies. Conclusions This study has confirmed the reliability of the ELISA for anti-SRP54 antibodies and provided insights into the clinical, serological, and pathological characteristics of South Korean patients with anti-SRP IMNM.

Background: Studies comparing the minimally invasive proximal chevron and Akin osteotomies (MIPCA) technique with conventional techniques, such as the open proximal chevron metatarsal osteotomy with the Akin procedure (open PCMO-Akin procedure), are limited. This study aimed to compare and evaluate operative MIPCA and open PCMO-Akin procedure outcomes in the surgical correction of moderate-to-severe hallux valgus deformities. Methods: We conducted a retrospective comparison of clinical and radiographic outcomes between the MIPCA and open PCMOAkin procedure in patients with a hallux valgus deformity, defined as a preoperative hallux valgus angle (HVA) of ≥ 30° and/or a first to second intermetatarsal angle of ≥ 13°. The postoperative complication rate was monitored in both groups for a minimum of 12 months. An unsatisfactory correction was defined as an HVA > 15° at final follow-up. Results: We assigned 58 and 99 patients to the MIPCA or open PCMO-Akin procedure group, respectively. At final follow-up, no significant differences were observed between the groups in terms of clinical and radiographic parameters (p > 0.05), with the exception of the distal metatarsal articular angle (DMAA) (p = 0.012). No statistically significant postoperative changes in the DMAA were observed in the MIPCA group (p = 0.875). Five patients (5.1%) experienced postoperative hallux varus in the open PCMO-Akin procedure group, whereas no such cases were observed in the MIPCA group. No statistically significant difference in the rate of unsatisfactory correction was observed between the groups at the final follow-up (MIPCA group, 15.5%; open PCMO-Akin procedure group, 10.1%; p = 0.315). Conclusions The MIPCA technique is a viable alternative to the open PCMO-Akin procedure for correcting moderate-to-severe hallux valgus deformities. Given the potential lack of postoperative changes in the DMAA following the MIPCA technique, careful consideration is advised when applying this technique to patients with a large DMAA.
