Objective: The purpose of this study is to evaluate the impact of tumor necrosis factor (TNF)-α blocker therapy on the Assessment of SpondyloArthritis international Society Health Index (ASAS-HI) among patients who have failed conventional nonsteroidal anti-inflammatory drugs. Methods: A comparative study was conducted involving axial spondyloarthritis (axSpA) patients treated with either TNF-α blocker or conventional therapy. Patient data, including demographics, disease characteristics, and ASAS-HI scores, were collected before and after treatment. Statistical analysis was performed to compare changes in ASAS-HI scores between the TNF-α blocker and the conventional therapy group. Results: The study population consisted of patients with axSpA, with a mean age of 38.3 years in conventional treatment group and 29.3 years in TNF-α blocker group. Most variables, including C-reactive protein levels, other comorbidities, and disease assessment scores showed no significant difference between groups. Longitudinal analysis within each treatment group from Week 0 to 12 showed no significant change in the conventional treatment group, whereas the TNF-α blocker group experienced a significant reduction in ASAS-HI scores, demonstrating the effectiveness of the treatment. The TNF-α blocker group exhibited a significantly greater improvement in ASAS-HI scores compared to the conventional therapy group. The Bath Ankylosing Spondylitis Functional Index and the Bath Ankylosing Spondylitis Disease Activity Index demonstrated strong positive correlations with ASAS-HI scores, indicating higher disease activity and functional limitation are associated with worse health outcomes in patients. Conclusion The research demonstrates that ASAS-HI scores significantly improve with TNF-α blocker therapy in axSpA patients, underscoring ASAS-HI's effectiveness as a tool for evaluating drug responses.

Esophageal perforation can lead to serious complications, and rapid diagnosis and treatment significantly affect the prognosis. Endoscopic vacuum-assisted closure (EndoVAC) therapy is widely accepted as a safe, well-tolerated, effective, versatile and practical procedure for the management of esophageal perforation in selected patients. We report the successful use of EndoVAC therapy for management of an esophageal perforation secondary to foreign body removal. A 56-year-old man presented to the emergency department for evaluation of chest pain after swallowing the plastic shell of a pill. Emergency endoscopy revealed an esophageal wall laceration (approximately 3 cm) and microperforation. The esophageal laceration and microperforation were limited to the mid-esophagus. The patient underwent EndoVAC therapy, which was repeated every 3–4 days for a total of six sessions over a period of 21 days. We observed improvement in the esophageal injury with granulation tissue formation during the fifth session. Subsequent follow-up evaluation, including esophagography and chest computed tomography confirmed complete healing of the esophageal injury. Following resumption of diet, the patienton a was discharged without any complications.

Amid the coronavirus disease 2019 era, concern about the safety of surgical teams related to surgical smoke (SS) is rising. As simple ventilation improvement methods (SVIMs), we replaced 4 of the 8 supply diffusers with a direction-adjustable louver-type, closed 2 of the 4 exhaust grills, and strengthened the sealing of the doorway. Dynamic changes in the concentration of particulate matter (PM) with sizes of < 1.0 μm (PM1.0) were measured using low-cost PM meters (LCPMs) at eight locations in the operating room (OR). SS concentration up to 4 minutes at the location of the surgeon, first assistant, and scrub nurse before and after SVIMs application decreased from 65.4, 38.2, 35.7 µg/m 3 to 9.5, 0.1 and 0.7 µg/m 3 respectively. A similar decrease was observed in the other 5 locations. SVIMs could effectively control SS and the LCPM was also effective in measuring SS in the OR or other spaces of the hospital.

PURPOSE: This study aimed to evaluate the influence of varying concentrations of sodium hyaluronate (SH) eye drops on corneal aberrations in normal individuals wearing silicone hydrogel contact lenses. METHODS: Normal individuals wearing silicone hydrogel contact lenses were enrolled in this study. Subjects were classified into two groups depending on the concentration of the preservative-free SH used (group 1, 0.1% SH; group 2, 0.3% SH). All subjects were asked to blink five times after instillation of the SH eye drop and before the Galilei measurements. Corneal aberrations were measured over the contact lenses before and after SH eye drop instillation. Visual acuity (VA) over the contact lenses was also measured both before instillation of the SH eye drop and after the subjects completed the five blinks. RESULTS: There was no change in VA after SH instillation in group 1; however, group 2′s VA significantly deteriorated after SH instillation. Changes in VA after SH instillation compared to baseline were significantly higher in group 2 than in group 1. Similarly, the increase in corneal aberrations after SH instillation was significant in group 2 but not significant in group 1. Among the significantly increased corneal aberration parameters, defocus was the main type in group 2. Changes in corneal aberrations after SH instillation compared to baseline were significantly higher in group 2 than in group 1. CONCLUSIONS: A 0.3%-concentration of SH increases corneal aberration and decreases VA in soft contact lens wearers. Defocus is the main type of aberration that increased in the 0.3% SH instillation group.

PURPOSE: We report a rare case of unilateral acute macular neuroretinoapthy in a young male. CASE SUMMARY: A 35-year-old male presented with a 2-day history of paracentral scotoma. He had suffered for 2 days from a flu-like illness, and his best corrected visual acuity was 20/20 OD and 20/20 OS. Pupillary reflex was normal and no relative afferent pupillary defects were not found. Ocular movement test was normal and pain on ocular movement was not noticed. Ophthalmoscopic examination of the left eye revealed multiple exudates lining the nasal macula toward the fovea. A Humphrey visual field study identified small paracentral scotoma. Spectral domain optical coherence tomography (SD-OCT, Heidelberg Engineering, Heidelberg, Germany) of the lesions showed a hyper-reflective lesion located in the outer plexiform layer and inflammatory cell infiltration. Fluorescent angiography was normal in the macula but showed late leak at the disc. The multifocal electroretinogram (mfERG) showed decreased foveal P1 amplitude in the left eye. The patient was diagnosed with acute macular neuroretinopathy and was treated with 60 mg of prednisolone. His subjective symptoms were improved, the paracentral scotoma disappeared, and the lesions appeared different upon SD-OCT; specifically, the hyper-reflective lesion disappeared and the outer plexiform layer showed thinning. CONCLUSIONS: Acute macular neuroretinopathy is a rare disease, and we report a case using SD-OCT and mfERG.

PURPOSE: To report a case series of patients experiencing side effects of 0.25% alcaftadine eye drops and to analyze the possible reasons for the side effects. CASE SUMMARY: Medical records of 90 patients who had a history of alcaftadine eye drop use were retrospectively analyzed. Eight out of the 90 patients (8.9%) showed ocular side effects that required discontinuation of the alcaftadine eye drops. All eight cases of alcaftadine side effects showed palpebral and bulbar conjunctival injection, watery discharge, and lid swelling. During additional history collection, all patients with alcaftadine side effects confessed of overuse (more than twice/day) of the eye drops. Anticipation for fast symptom relief was the main reason for the alcaftadine overuse. In all side effect cases, patients were asked to stop alcaftadine eye drops and use preservative-free artificial tears and steroid eye drops. After discontinuation of 0.25% alcaftadine eye drops, regression of palpebral and bulbar conjunctival injection and lid swelling was observed. CONCLUSIONS: Overuse of 0.25% alcaftadine eye drops can induce ocular surface toxicity possibly due to toxicity of drug itself. The possible side effects of overuse of 0.25% alcaftadine eye drops should be fully explained to all patients before use.

BACKGROUND AND OBJECTIVES: Ancillary tests such as BRAF(V600E) mutation or immunohistochemical (IHC) assays have been utilized as complements to morphological criteria in diagnosing subsets of papillary thyroid carcinoma (PTC). Utilizing results from analysis by The Cancer Genome Atlas (TCGA), we evaluated the diagnostic value and feasibility of these ancillary tests in diagnosing follicular variant PTC (FVPTC). MATERIALS AND METHODS: Clinical data and tissue samples were analyzed from 370 PTC patients, who had undergone thyroidectomy between December 2003 and July 2014. PTC was limited to conventional PTC (CVPTC), tall cell variant PTC (TCPTC), and FVPTC. Using multivariate analyses, FVPTC cases were compared to CVPTC and TCPTC cases. Surgical specimens were pyrosequenced for BRAF(V600E) mutation or stained for IHC markers such as CD56, galectin-3, cytokeratin 19 (CK19), or CD31. For the validation, a comprehensive analysis was performed for BRAF(V600E) mutation and quantitative mRNA expressional difference in TCGA. RESULTS: Demographic differences were not observed between 159 CVPTC, 103 TCPTC, and 108 FVPTC cases. BRAF(V600E) mutation predominated in CVPTC+TCPTC group, but not in FVPTC group (78.4% vs. 18.7%, p<0.001), as suggested by TCGA (57.4% vs. 12.1%, p<0.0001). IHC markers significantly distinguished FVPTC cases from CVPTC+TCPTC cases. CD56 exhibited more intense staining in FVPTC cases (21.1% vs. 72.0%, p<0.001). Galectin-3 and CK19 yielded limited values. CD31 correlated with lymphovascular invasion (r=0.847, p<0.001). In analysis of TCGA, mRNA differential expression of these genes revealed their corresponding upregulation or downregulation. CONCLUSION: BRAF(V600E) mutation or TCGA-validated IHC assay could be recommended as ancillary tests for classifying PTC.

PURPOSE: To report the first case of the Raoultella planticola endophthalmitis after the phacoemulsification and posterior chamber multi-focused intraocular lens (IOL) implantation. CASE SUMMARY: A healthy 49-year-old male visited our clinic with a sudden visual disturbance and ocular pain 2 days after phacoemulsification and multi-focused IOL implantation in his right eye. On initial ophthalmic examination, severe corneal edema and hypopyon were observed. The retina could not be visualized due to vitreous opacity and anterior chamber inflammation. Therefore, the patient immediately underwent pars plana vitrectomy. Vancomycin hydrogen chloride (HCl) 0.3 mg/0.1 mL was injected into the anterior part and vancomycin HCl 1.0 mg/0.1 mL and ceftazidime 2.0 mg/0.1 mL were injected into the intravitreal part. The culture test of aqueous humor and vitreous body fluid revealed Raoultella planticola, thus, systemic antibiotic (ceftazidime) and antibiotic eye drops (vancomycin and ceftazidime) were administered. After 4 months of follow-up, best-corrected visual acuity improved to 20/20 in the affected eye after surgery. CONCLUSIONS: In the present case, we found that endophthalmitis due to Raoultella planticola can be successfully treated. We suggest that atypical bacteria should be considered in the differential diagnosis of endophthalmitis after cataract surgery.

PURPOSE: To report a case of maculopathy after exposure to a high-voltage spark. CASE SUMMARY: A 40-year-old male patient visited our clinic complaining of visual disturbance in both eyes 1 day after exposure to a high voltage arc discharge. His best corrected visual acuity was 4/20 in both eyes. On fundus examination, a yellowish retinal scar was observed at the foveal area. The spectral domain optical coherence tomography (SD-OCT) showed inner segment/outer segment line disruption. The best corrected visual acuity was 4/20 in both eyes and SD-OCT showed a remaining inner segment/outer segment line disruption after 3 years. CONCLUSIONS: Maculopathy can result from exposure to a high voltage arc discharge exposure.

PURPOSE: Acute care surgery (ACS) models have evolved worldwide over the last decade. However, South Korea has an established trauma system and does not consider the ACS model. This study compares the management and outcome of emergency cholecystectomy in the ACS model to those of traditional on-call attending surgeon model for emergency surgery. METHODS: Retrospectively collected data for patients who underwent emergency cholecystectomy from May 2013 to January 2015 was analyzed to compare data from a traditional on-call system (OCS) and ACS. RESULTS: One hundred and twenty-four patients were enrolled in the study (62 patients ACS vs. 62 patients OCS). Hospital stay (days) (ACS=4.29±2.49 vs. OCS=4.82±4.48, p=0.46) and stay in emergency room (minutes) (ACS=213.10±113.99 vs. OCS=241.10±150.73, p=0.20) did not differ significantly between groups. Operation time (minutes) was significantly shorter in the ACS than OCS group (389.97±215.21 vs. 566.35±290.14, p<0.001). Other clinical variables (sex, open-conversion rate, whether the operation was performed at night/holiday, intensive care unit admission rate) did not differ between groups. There was no mortality and readmission. CONCLUSION: The implementation of the ACS led to shorter operation time and no increase of postoperative mortality and complication.
