Bony Bankart lesions present considerable challenges in shoulder surgery, particularly when large. While smaller lesions can often be treated effectively using the single-row technique, larger lesions require more complex approaches. Several arthroscopic techniques have been developed to manage these lesions. Although the double-row technique is effective, it has the disadvantage of placing suture material on the articular surface. In contrast, the transosseous technique permits adequate compression and surface contact without involving the articular surface; however, it is technically demanding and frequently requires specialized instruments. This technical note describes a simplified arthroscopic transosseous repair method for bony Bankart lesions using standard spinal needles and Kirschner wires, eliminating the need for specialized equipment while ensuring secure fixation and optimal surface contact.

Background: Cervical spine magnetic resonance imaging (MRI) can reveal incidental extraspinal findings (IESFs) unrelated to the primary evaluation of cervical radiculopathy or myelopathy. Recognizing these lesions is crucial because some may require further investigation or treatment. Methods: We retrospectively reviewed 2,286 non-contrast cervical spine MRI scans performed between January 2019 and July 2024 in patients presenting with neck pain, shoulder pain, or neurological deficits suggestive of cervical radiculopathy or myelopathy. Patients with a history of malignancy, known head and neck tumors, or previous cervical surgeries were excluded. Boardcertified radiologists initially interpreted all scans. Documented IESFs were categorized into 5 groups: thyroid nodules, lymphadenopathy, soft-tissue tumors, brain lesions, and other head and neck lesions. Clinical follow-up data were analyzed to determine lesion outcomes. Statistical comparisons of demographics were performed using chi-square, t-test, and Mann-Whitney U-test. Results: IESFs were identified in 103 of 2,286 scans (4.5%). Thyroid nodules were the most common (n = 64, 2.0%), followed by lymphadenopathy (n = 16, 0.5%). Females had a higher incidence of IESFs than males (64.4% vs. 35.6%, p < 0.001), and the mean age was significantly higher in the IESF group (58.4 vs. 54.7 years, p = 0.033). Of 94 patients with available follow-up, 7 (7.4%) were confirmed malignant: 5 thyroid nodules and 2 lymphadenopathies. Two additional cases underwent surgery for pituitary and parathyroid adenomas. Four IESFs went unrecognized on initial review, underscoring the risk of missed diagnoses when the clinical workload is high. Conclusions IESFs in cervical spine MRI were detected in 4.5% of cases, with a notable subset being malignant. These findings emphasize the importance of systematic review protocols and interdisciplinary collaboration to ensure clinically significant lesions are identified and managed promptly.

Janus kinase (JAK) inhibitors are an important treatment option for ulcerative colitis, providing rapid onset of action, oral administration, and efficacy even after biologic failure. The 3 approved agents—tofacitinib, filgotinib, and upadacitinib—differ in JAK isoform selectivity, leading to clinically meaningful differences in efficacy and safety. Evidence from network meta-analyses, clinical trials, and real-world studies consistently shows that upadacitinib provides the highest efficacy for induction and maintenance of remission, whereas filgotinib demonstrates the most favorable safety profile. The strong efficacy of upadacitinib and tofacitinib is particularly relevant in patients with severe disease, including acute severe ulcerative colitis, and upadacitinib maintains high efficacy regardless of prior advanced therapy exposure. JAK inhibitors also benefit extraintestinal manifestations. Although risks such as herpes zoster, serious infection, thromboembolism, and major cardiovascular events differ among agents, long-term data suggest generally acceptable safety when used appropriately. Intraclass JAK-to-JAK cycling is feasible, with about half of patients achieving steroid-free clinical remission in retrospective cohorts. Based on mechanistic, clinical, and real-world evidence, filgotinib may be a first-line option for patients with lower disease activity or when safety is a priority, whereas upadacitinib or tofacitinib may be preferred in higher disease activity. Strategically selecting agents may improve durability and outcomes.

Background: and Purpose Intraoperative visual evoked potential (VEP) monitoring has been studied mainly in pituitary adenoma, while its role in nonpituitary suprasellar tumors has remained unclear. This study evaluated the predictive usefulness of intraoperative VEP monitoring during endoscopic endonasal surgery (EES) and aimed to identify optimal alarm criteria for visual outcomes. Methods: We retrospectively analyzed a cohort of 87 patients who underwent EES with intraoperative VEP monitoring between April 2021 and September 2023. Visual outcomes were evaluated preoperatively and at short-term (≤3 months) and long-term (12 months) followups, with visual deterioration at these time points defined as worsening of either visual acuity or the visual field. Reductions in the VEP amplitude were quantified using both the maximum intraoperative decrease and the final amplitude after recovery. Receiver operating characteristic (ROC) curve analyses were performed to identify the optimal alarm thresholds, and the sensitivity, specificity, positive predictive value, and negative predictive value were calculated for short-term and long-term visual deteriorations. Results: Short-term and long-term visual deteriorations were detected in 12 (9.2%) and 5 (3.8%) of the 130 analyzed eyes, respectively. ROC curve analyses identified ≥40% and ≥30% reductions in the N75–P100 amplitude as optimal alarm criteria for short-term and long-term visual deteriorations, respectively. A 30% reduction without intraoperative recovery demonstrated markedly higher sensitivity than the conventional 50% alarm threshold for short-term (58.3% vs. 33.3%) and long-term (80.0% vs. 20.0%) outcomes, while maintaining acceptable specificity (82.2% and 80.8%, respectively). Conclusions A 30% reduction in amplitude represents a more-sensitive and clinically relevant alarm threshold than a 50% reduction for intraoperative VEP monitoring during EES for nonpituitary suprasellar tumors. Incorporating both the magnitude and recovery pattern of VEP amplitude changes may improve the accuracy of predictions of long-term visual deterioration. However, the potential for false positives warrants cautious interpretation, and further studies are needed to validate the impact of intraoperative VEP monitoring on visual outcomes.

Objective: Lipid-lowering drugs are known to cause various muscle-related side effects;however, it remains unclear whether their use contributes to reduced muscle mass and sarcopenia. This study aimed to evaluate the association between the use of lipid-lowering drugs and both muscle mass and the prevalence of sarcopenia. Methods: We conducted a cross-sectional analysis using data from 18,668 adults aged ≥20 years from the Korea National Health and Nutrition Examination Survey 2008–2011.Sarcopenia was defined based on appendicular skeletal muscle mass (ASM), measured using dual-energy X-ray absorptiometry. The association between hyperlipidemia medication and the prevalence of sarcopenia was estimated using complex samples logistic regression. Results: Patients with hyperlipidemia exhibited lower ASM/wt than those without hyperlipidemia. After adjusting for potential confounders, including current lipid profiles, ASM/wt did not differ significantly between the general population and hyperlipidemic patients not receiving medication. However, individuals taking lipid-lowering drugs demonstrated significantly lower ASM/wt. This trend was mirrored in sarcopenia prevalence, with odds ratios of 2.89 (95% confidence interval [CI], 1.95–4.28) in men and 1.68 (95% CI, 1.26–2.24) in women (p<0.01 for both). Notably, only participants on lipid-lowering drugs showed a progressive decline in ASM/wt and an increased risk of sarcopenia with longer duration of hyperlipidemia. Conclusion These results suggest that the use of lipid-lowering drugs may contribute to a decrease in muscle mass and a higher risk of sarcopenia. However, the generalizability of these results is limited, and further longitudinal studies are required to confirm the association.

Background: Cough is a prominent symptom of chronic respiratory diseases, including asthma, idiopathic pulmonary fibrosis (IPF), chronic obstructive pulmonary disease (COPD), and bronchiectasis (BE). Some patients develop chronic cough (CC), defined as lasting more than 8 weeks, yet its characteristics remain poorly understood. This study aimed to characterize CC across various chronic respiratory diseases using validated cough assessment tools. Methods: The Cough Assessment in Chronic Respiratory Diseases (COASESS) study, a multicenter, prospective cross-sectional study, was conducted at 10 university hospitals. CC was evaluated in terms of intensity (numeric rating scale [NRS]), frequency (cough symptom score [CSS]), and quality of life (using the cough assessment test [COAT] and Leicester cough questionnaire [LCQ]). Cough hypersensitivity was assessed with the cough hypersensitivity questionnaire (CHQ). Data on age, sex, and smoking status were also collected. Results: Among the 303 enrolled patients, 266 with chronic respiratory diseases were included in the analysis. Patients with asthma were younger, predominantly female, and non-smokers, whereas those with COPD and IPF were older males who had previously smoked (p<0.001). Scores for COAT, LCQ, NRS, and CSS showed significant differences across the diseases, with asthma and IPF patients experiencing a greater symptom burden and lower quality of life compared to those with COPD or BE (p<0.001). Although CHQ total scores were similar across groups, asthma patients more frequently reported triggers such as talking and post-nasal drip. Conclusion This study revealed distinct characteristics of CC across different chronic respiratory diseases. Asthma and IPF were associated with a higher symptom burden, and cough hypersensitivity varied depending on the underlying condition. These findings highlight the necessity for disease-specific assessments and management strategies for CC.

Background: Research on the relationship between the progression of interstitial lung abnormalities (ILA) and serum biomarkers, including white blood cell differential counts and Krebs von den Lungen-6 (KL-6), is limited. This study aimed to examine the clinical characteristics of patients with ILA and evaluate the association between disease progression and serum biomarkers. Methods: This retrospective cohort study analyzed data from 159 patients (63 with ILA and 74 with interstitial lung diseases) between October 2021 and September 2022. Data collected included clinical characteristics, pulmonary function tests, chest computed tomography (CT), complete blood cell counts, and KL-6 levels. In 52 of these patients who had previously undergone chest CT, the utility of serum biomarkers in reflecting radiologic progression was assessed using receiver operating characteristic curve analysis. Results: Patients with ILA exhibited clinical characteristics similar to those with idiopathic pulmonary fibrosis. Serum KL-6 levels did not correlate with forced vital capacity or diffusing capacity of the lung for carbon monoxide in patients with ILA. Among the 52 patients with ILA, 13 demonstrated radiologic progression. Serum KL-6 displayed moderate predictive performance, with area under the curves ranging from 0.57 to 0.89 (p=0.014) for radiologic progression. Levels of KL-6 greater than 400 U/mL were more frequently observed in patients with radiologic progression (61.5% vs. 20.5%, p=0.006). In multivariate analysis, age and KL-6 were independently associated with radiologic progression in patients with ILA. Conclusion Serum KL-6 levels may serve as a potential indicator of ILA progression in asymptomatic patients. Those with KL-6 levels exceeding 400 U/mL should be closely monitored for radiologic progression.

Background: Pulmonary rehabilitation (PR) is a key intervention for chronic obstructive pulmonary disease (COPD); however, adherence remains suboptimal, particularly in patients with low physical activity (PA) despite preserved physical capacity (PC). This study aimed to identify factors associated with low PA, with a focus on patient-reported outcomes (PROs). Methods: In this prospective study, COPD patients were categorized according to daily moderate-to-vigorous PA measured using Fitbit devices: ≥30 minutes/day (‘Do do’) and <30 minutes/day (‘Don’t do’). Baseline characteristics, pulmonary function, and exercise capacity assessed by 6-minute walk distance (6MWD) were evaluated. PROs included the modified Medical Research Council (mMRC) dyspnea scale, COPD Assessment Test (CAT), and Patient Health Questionnaire-9 (PHQ-9). Logistic regression analysis was performed to identify factors independently associated with low PA. Results: Among 96 patients, 44 were classified as ‘Do do’ and 52 as ‘Don’t do.’ The ‘Don’t do’ group showed significantly lower 6MWD (424 m vs. 488 m, p=0.005) and lower forced expiratory volume in 1 second (46.73% vs. 54.48%, p=0.005). They also reported higher dyspnea scores (mMRC 1.77 vs. 1.30, p=0.019). Greater breathlessness measured by CAT was independently associated with low PA (odds ratio, 1.31; 95% confidence interval, 1.06 to 1.62), even after adjustment for 6MWD and pulmonary function. This association persisted in patients with preserved PC. Conclusion Low PA in COPD is influenced not only by objective physical limitations but also by subjective symptom burden, particularly dyspnea. Integrating PROs into PR assessment may facilitate identification of barriers and improve adherence to rehabilitation programs.

Purpose: Hereditary spastic paraplegia (HSP) refers to a group of genetic neurodegenerative diseases marked by gradually worsening spasticity and hyperreflexia in the lower extremities. This study aimed to describe the clinical and genetic characteristics of Korean patients with spastic paraplegia. Materials and Methods: We retrospectively reviewed medical records of 69 patients with spastic paraplegia from 54 unrelated families between 2002 and 2024. Genetic, clinical, electrophysiological, and radiological features were comprehensively analyzed. Results: Causative genes were identified in 34 (63%) of 54 unrelated families; SPAST, detected in 26 families, was the most prevalent. Seven novel pathogenic variants were identified. Clinically, the median age of symptom onset was 25 years [14.0–37.0]. Out of 69 patients with spastic paraplegia, 51 (74%) presented with the pure form of spastic paraplegia, which included all patients with SPG4. Spastic gait was a universal feature in all patients. Urinary dysfunction was present in 42 (61%) patients. Additional neurologic manifestations included peripheral neuropathy 9 (13%), cognitive impairment 5 (7%), upper limb weakness 4 (6%), dysarthria 4 (6%), dysphagia 3 (4%), ataxia 3 (4%), and scoliosis 1 (3%). Brain MRI findings demonstrated a thin corpus callosum in two patients with SPG11; all patients with SPG4 had normal findings. Spine MRI revealed spinal cord atrophy in 16 (27%) patients, including 6 (21%) patients with SPG4. Conclusion The study comprehensively reviewed genetic and clinical spectra of spastic paraplegia in Korean patients, emphasizing the predominance of SPAST as the causative gene and underscoring the genetic and phenotypic heterogeneity of spastic paraplegia.

Objective: This study examined whether baseline levels of 14 serum biomarkers predicted antidepressant remission differently by sex at 12 weeks and 12 months. Methods: In a prospective cohort, 1,086 outpatients with depressive disorders received stepwise antidepressant treatment following a naturalistic protocol. Baseline serum samples were analyzed for biomarkers from six systems: immune (high-sensitivity C-reactive protein, tumor necrosis factor-alpha, interleukin-1 beta, interleukin-6, interleukin-4, interleukin-10), metabolic (leptin, ghrelin, total cholesterol), neurotrophic (brain-derived neurotrophic factor), neurotransmitter (serotonin), endocrine (cortisol), and nutritional (folate, homocysteine). Remission, defined as a Hamilton Depression Rating Scale scores ≤ 7, was assessed at 12 weeks and 12 months. Logistic regression models with biomarker-by-sex interaction and stratified analyses were used, adjusting for clinical covariates. Results: Higher baseline serotonin predicted 12-week remission in males but not in females. At 12 months, lower leptin and higher folate predicted remission only in males, while lower cortisol predicted remission only in females. These showed significant biomarker-sex interactions. No sex-specific interactions were found for immune markers. Conclusion Baseline serum biomarkers across biological systems showed sex-specific associations with treatment outcomes. Neurotransmitter, metabolic, endocrine, and nutritional markers may offer predictive value for sex-tailored, biomarker-informed treatment strategies in depression.
