The fundamental principles for treating ankle fractures, as with other intra-articular fractures, are anatomical reduction and stable internal fixation. Despite successful reduction, between 14% and 40% of patients continue to experience persistent pain or unsatisfactory functional outcomes. Furthermore, approximately 1% of patients progress to post-traumatic arthritis, necessitating further surgical intervention. Ankle fractures are frequently accompanied by intra-articular injuries, including osteochondral lesions, ligament tears, and syndesmosis injuries. Arthroscopy is becoming increasingly prevalent in managing acute ankle fractures by assessing intra-articular damage and facilitating accurate reduction. This review examined the role and indications for arthroscopy in ankle fractures, particularly emphasizing its benefits in diagnosing and managing associated injuries, including osteochondral lesions, syndesmosis, and deltoid ligament injuries. Furthermore, arthroscopy facilitates fracture reduction, offering a minimally invasive approach with a shorter recovery period and enhanced visualization. Its use extends to pediatric fractures and complex cases such as Maisonneuve and calcaneal fractures, potentially improving outcomes while minimizing complications. Understanding the evolving indications and benefits of arthroscopy for ankle fractures can lead to improved clinical outcomes and reduced complications.

Purpose: We examined the association between age-related macular degeneration (AMD) and arthritis. Methods: Using data from the Korea National Health and Nutrition Examination Survey for 2017 and 2018, we conducted a complex sample analysis of 6,993 individuals with recorded information on AMD, as well as the diagnosis and treatment of osteoarthritis (OA) and rheumatoid arthritis (RA). We compared the diagnosis and treatment of arthritis between the AMD and control groups using logistic regression analysis, with a specific focus on the treatment among patients with arthritis. Results: In the AMD group (n = 1,118) and the control group (n = 5,875), univariate logistic regression analysis showed substantial differences in the diagnosis and treatment of OA and RA. However, after adjusting for age, alcohol consumption, diabetes mellitus, and hypertension in multivariate logistic regression analysis, these differences were no longer substantial. Among patients with OA (n = 246 in the AMD group and n = 821 in the control group), there was a significant association between AMD and OA treatments (odds ratio 1.511, 95% confidence interval 1.051-2.172). Conclusions Patients diagnosed with and treated for OA had a higher likelihood of concurrent AMD than those who did not receive treatment. Therefore, ophthalmic examinations and closer monitoring are recommended for these patients.

Purpose: To analyze the incidence of vitreous floaters after intravitreal antivascular endothelial growth factor injection and the effectiveness of the inverse tapping technique, which involves tapping the syringe with the needle downwards to prevent the entry of air bubbles during injection. Methods: The study enrolled patients undergoing their first intravitreal injection for exudative age-related macular degeneration or diabetic macular edema. The patients were divided into two groups: those who received an injection after inverse tapping (IT group) and controls who received the injection without tapping. Patients who consented to the study were randomly assigned to the IT group and the control group through block randomization. One week after injection, a questionnaire was used to assess the presence of vitreous floaters; those who reported them were examined via optical coherence tomography and wide fundus photography. Results: Of the 39 patients in the IT group, two (5.1%) reported floaters 1 week after injection. By contrast, eight (20.5%) of the 39 controls reported them, with a significant difference (p = 0.042). Patients with floaters were significantly younger. Posterior vitreous detachment, as evaluated by pre-injection optical coherence tomography, was observed in 10.0% of those with floaters and 76.5% of those without them. Conclusions The occurrence of vitreous floaters after intravitreal injection is related to age and the presence of posterior vitreous detachment. The use of the inverse tapping technique may help reduce these after intravitreal injection.

Background/Aims: Fexuprazan is a novel potassium-competitive acid blocker that could be of benefit to patients with gastric mucosal injury. The aim of this study was to assess the 2-week efficacy and safety of fexuprazan in patients with acute or chronic gastritis. Methods: In this study, 327 patients with acute or chronic gastritis who had one or more gastric erosions on endoscopy and subjective symptoms were randomized into three groups receiving fexuprazan 20 mg once a day (q.d.), fexuprazan 10 mg twice a day (b.i.d.), or placebo for 2 weeks. The posttreatment assessments were the primary endpoint (erosion improvement rate), secondary endpoints (cure rates of erosion and edema and improvement rates of redness, hemorrhage, and subjective symptoms), and drug-related adverse events. Results: Among the patients, 57.8% (59/102), 65.7% (67/102), and 40.6% (39/96) showed erosion improvement 2 weeks after receiving fexuprazan 20 mg q.d., fexuprazan 10 mg b.i.d., and placebo, respectively. Both fexuprazan 20 mg q.d. and 10 mg b.i.d. showed superior efficacy to the placebo (p=0.017 and p<0.001, respectively). Likewise, both fexuprazan 20 mg q.d. and 10 mg b.i.d. also showed higher erosion healing rates than the placebo (p=0.033 and p=0.010, respectively). No difference was noted in the edema healing rate and the improvement rates for redness, hemorrhage, and subjective symptoms between the fexuprazan and placebo groups.No significant difference was noted in the incidence of adverse drug reactions. Conclusions Fexuprazan 20 mg q.d. and 10 mg b.i.d. for 2 weeks showed therapeutic efficacy superior to that of placebo in patients with acute or chronic gastritis (ClinicalTrials.gov identifier NCT04341454).

Purpose: To predict the presence of tractional retinal detachment (TRD) in eyes with dense vitreous hemorrhage (VH) and proliferative diabetic retinopathy (PDR) by evaluating the status of posterior vitreous detachment (PVD) in fellow eyes using optical coherence tomography (OCT). Methods: A total of 44 eyes from 22 patients who underwent vitrectomy due to dense VH with PDR were enrolled. Using OCT, the PVD status in the fellow eye was divided into two groups (incomplete and complete PVD). The incomplete PVD group included eyes without PVD and eyes with partial PVD. B-scan ultrasonography was performed on eyes with dense VH to evaluate the presence of TRD. Both OCT and B-scan images were reviewed by four ophthalmologists (two novices and two experienced), and the interobserver agreement was evaluated. Results: There was a difference in the interobserver agreement regarding the presence of TRD in eyes with dense VH evaluated by B scan between novice and experienced ophthalmologists (novice, κ = 0.421 vs. experienced, κ = 0.814), although there was no difference between novice and experienced ophthalmologists in the interobserver agreement regarding the status of PVD in the fellow eye evaluated by OCT (novice, κ = 1.000 vs. experienced, κ = 1.000). All observed TRD during vitrectomy occurred in eyes with incomplete PVD in the fellow eye. Logistic regression analysis revealed a statistically significant relation between TRD and the age of the patient (odds ratio [OR], 0.874; p = 0.047), and between TRD and incomplete PVD in the fellow eye evaluated by OCT (OR, 13.904; p = 0.042). Conclusions Evaluation of the PVD status in the fellow eye using OCT may be a useful predictor for detecting the presence of TRD in eyes with dense VH and PDR.

Purpose: To explore the association between the visual and anatomical outcomes and the choroidal vascularity index (CVI) post-intravitreal injection in patients with macular edema associated with branch retinal vein occlusion (BRVO). Methods: We conducted a retrospective review of medical records of 50 patients (27 eyes treated with anti-vascular endothelial growth factor and 23 eyes treated with a dexamethasone implant) with BRVO and macular edema who underwent intravitreal injections from January 2017 to October 2020. We measured the central macular thickness (CMT), subfoveal choroidal thickness, and CVI of the BRVO eyes and the fellow eyes using optical coherence tomography and then analyzed the correlation between these measurements and visual and anatomical outcomes. Results: After six months of treatment, the best corrected visual acuity improved, and CMT decreased. Multiple linear regression analysis revealed that factors associated with best corrected visual acuity improvement at six months were fellow eye CVI (standardized β = 0.346, p = 0.008), ellipsoid zone integrity (standardized β = 0.398, p = 0.001), and initial best corrected visual acuity (standardized β = 0.590, p < 0.001). Initial CMT (standardized β = 0.563, p < 0.001) was the only factor associated with the decrease in CMT at six months. Conclusions In cases of severe macular edema, accurate evaluation of choroidal vessels can be challenging due to shadowing. We discovered that a larger CVI in the fellow eye was associated with greater visual improvement in patients with BRVO and macular edema. CVI could be a prognostic factor for predicting treatment outcomes in BRVO patients, suggesting that the choroidal vascular status may play a role in the pathophysiology of BRVO.

Background: New genome sequencing technologies with enhanced diagnostic efficiency have emerged. Rapid and timely diagnosis of treatable rare genetic diseases can alter their medical management and clinical course. However, multiple factors, including ethical issues, must be considered. We designed a targeted sequencing platform to avoid ethical issues and reduce the turnaround time. Methods: We designed an automated sequencing platform using dried blood spot samples and a NEOseq_ACTION panel comprising 254 genes associated with Mendelian diseases having curable or manageable treatment options. Retrospective validation was performed using data from 24 genetically and biochemically confirmed patients. Prospective validation was performed using data from 111 patients with suspected actionable genetic diseases. Results: In prospective clinical validation, 13.5% patients presented with medically actionable diseases, including short- or medium-chain acyl-CoA dehydrogenase deficiencies (N=6), hyperphenylalaninemia (N=2), mucopolysaccharidosis type IVA (N=1), alpha thalassemia (N=1), 3-methylcrotonyl-CoA carboxylase 2 deficiency (N=1), propionic acidemia (N=1), glycogen storage disease, type IX(a) (N=1), congenital myasthenic syndrome (N=1), and citrullinemia, type II (N=1). Using the automated analytic pipeline, the turnaround time from blood collection to result reporting was <4 days. Conclusions This pilot study evaluated the possibility of rapid and timely diagnosis of treatable rare genetic diseases using a panel designed by a multidisciplinary team. The automated analytic pipeline maximized the clinical utility of rapid targeted sequencing for medically actionable genes, providing a strategy for appropriate and timely treatment of rare genetic diseases.
