PURPOSE: We investigated chief complaints and ocular disorders in infants under one year of age and analyzed the association between complaints and disorders. METHODS: The medical records of 815 infants were reviewed. Chief complaints were grouped into the following 11 categories: eyelid drooping, epiphora (tearing), ocular discharge, lid swelling, eyelashes touching the eyeball, abnormalities of the anterior segment, abnormal eyeball movement (e.g., squint or nystagmus), red eye, trauma, poor eye contact, and miscellaneous. We performed ophthalmologic examinations at the doctors' discretion and analyzed the relationship between chief complaint and final diagnosis. RESULTS: Mean age of visiting the outpatient clinic was 6.09 +/- 3.07 months. The most common complaint was ocular discharge, followed by abnormal eyeball movement, epiphora, and eye redness. Among infants with ocular discharge, most were attributed to congenital nasolacrimal duct obstruction (155 infants) and conjunctivitis (75 infants). A total of 160 guardians complained of abnormal eyeball movement and 86 of 160 infants (51.9%) suffered from pseudoesotropia. Additionally, exodeviation and esodeviation was found in 17.9% and 16.4% of infants, respectively. Eight guardian complained of poor eye contact in their infants and these infants were diagnosed with retinal disorders (3), congenital optic nerve disorders (2), cataract (1), glaucoma (1), and high hyperopia (1). CONCLUSIONS: The most common ocular symptoms in infants under one year of age included ocular discharge, epiphora, and eye redness. However, infants with poor eye contact or suspected abnormal eye movement should undergo a full ophthalmologic examination.

PURPOSE: To investigate the differences in retinal nerve fiber layer (RNFL) change and optic nerve head parameters between non-arteritic anterior ischemic optic neuropathy (NAION) and open angle glaucoma (OAG) with altitudinal visual field defect. METHODS: Seventeen NAION patients and 26 OAG patients were enrolled prospectively. The standard visual field indices (mean deviation, pattern standard deviation) were obtained from the Humphrey visual field test and differences between the two groups were analyzed. Cirrus HD-OCT parameters were used, including optic disc head analysis, average RNFL thickness, and RNFL thickness of each quadrant. RESULTS: The mean deviation and pattern standard deviation were not significantly different between the groups. In the affected eye, although the disc area was similar between the two groups (2.00 +/- 0.32 and 1.99 +/- 0.33 mm2, p = 0.586), the rim area of the OAG group was smaller than that of the NAION group (1.26 +/- 0.56 and 0.61 +/- 0.15 mm2, respectively, p < 0.001). RNFL asymmetry was not different between the two groups (p = 0.265), but the inferior RNFL thickness of both the affected and unaffected eyes were less in the OAG group than in the NAION group. In the analysis of optic disc morphology, both affected and unaffected eyes showed significant differences between two groups. CONCLUSIONS: To differentiate NAION from OAG in eyes with altitudinal visual field defects, optic disc head analysis of not only the affected eye, but also the unaffected eye, by using spectral domain optical coherence tomography may be helpful.

The push for high quality care in all fields of medicine highlights the importance of establishing and adhering to quality indicators. In response, several gastrointestinal societies have established quality indicators specific to Barrett's esophagus, which serve to create thresholds for performance while standardizing practice and guiding value-based care. Recent studies, however, have consistently demonstrated the lack of adherence to these quality indicators, particularly in surveillance (appropriate utilization of endoscopy and obtaining biopsies using the Seattle protocol) and endoscopic eradication therapy practices. These findings suggest that innovative interventions are needed to address these shortcomings in order to deliver high quality care to patients with Barrett's esophagus.

Aims: Bacterial biofilms can be defined as a community of microorganisms in which cells adhere to one another on a surface and are embedded in a protective matrix of lipids, nucleic acids, proteins and polysaccharides. Biofilm produced by Vibrio cholerae represents a significant threat to food safety, as they can lead to the transmission of diseases. Hence, the purpose of this study is to review the effect of different types of sodium chloride on minimum biofilm eradication concentration (MBEC) and morphology of biofilm formation of Vibrio cholerae. Methodology and results: In this study, V. cholerae biofilm was treated with four different types of sodium chloride; ‘Bario’ salt, ‘Bakelalan’ salt, commercial sodium chloride and laboratory sodium chloride. By using MBEC test, the concentration of sodium chloride needed to eradicate the biofilm of V. cholerae was determined. Based on the result obtained, commercial sodium chloride and laboratory sodium chloride showed the highest anti-biofilm activity against the biofilm of V. cholerae at 500 mg/mL concentration while no complete eradication of V. cholerae biofilm was achieved when treated with Sarawak local salts (‘Bario’ salt and ‘Bakelalan’ salt). However, noticeable inhibitions of bacterial growth were seen at the highest concentration of local salts. Conclusion, significance and impact of study Commercial sodium chloride and laboratory sodium chloride showed a better anti-biofilm activity towards the V. cholerae biofilm formation as compared to the local salts. Thus, commercial sodium chloride and laboratory sodium chloride can be an effective anti-biofilm agent to mitigate the biofilm formation of V. cholerae. Further studies can be done to determine the MBEC values of other pathogenic bacteria against commercial and laboratory sodium chloride.

BACKGROUND: The shortage of donor organs is the main problem that needs to be solved in Korea as well as in other countries. To expand the donor pool, we retrospectively reviewed the brain-dead patients who expired without organ donation in the neurosurgical intensive care units (NICU) and evaluated the potential deceased donors (PDDs). METHODS: Between January 2008 and December 2008, PDDs who expired without organ donation in the NICU were recruited from 52 secondary or tertiary referral hospitals in Korea. The data of a total 2,288 PDD cases were collected from the questionnaire. Of these, 1,980 cases were eligible for analysis. RESULTS: There were 1,166 males (58.9%) and 793 females (40.1%) with a mean age of 57.6+/-18.0 years (21.2% in the 5th decade; 21.0% in the 6th decade). The most common cause of death of PDDs was cerebrovascular accident (n=1,034; 52.2%). Glasgow Coma scale was 3 in 23.1% and 4 in 12.1% of the PDDs. Craniotomy was performed in 996 patients (50.3%). Sepsis developed in 276 patients (14.0%) among the total PPDs. Diagnostic procedure for assessment of brain death was performed in 194 patients (9.8%). The seroprevalence of HBsAg and HCVAb was 1.7% and 0.6%, respectively. The mean AST/ALT level on admission and after brain death were 80.9+/-344.9/49.0+/-162.19 and 308.6+/-1,485.2/142.5+/-596.27 IU/L, respectively. Uriney protein level was normal in 1,221 patients (61.7%) after brain death. Of the 1980 PDDs, 19 patients (1%) donated their organs for transplantation. CONCLUSION: Only a small percentage (1%) of PDDs in the NICU donated their organs in Korea. We suggest that continuous and active donor action is needed to increase organ donation from the potential deceased donors.

Background/Aims: Galectin-3 plays a key pathogenic role in cardiac hypertrophy and heart failure. The present study aimed to investigate the effects of galectin-3 on cardiomyopathy – related factors and cardiac contractility in a rat model of cirrhotic cardiomyopathy. Methods: Rats were divided into two sets, one for a functional study, the other for cardiac contractile-related protein evaluation. There were four groups in each set: sham operated and sham plus N-acetyllactosamine (N-Lac, a galectin-3 inhibitor; 5 mg/kg); bile duct ligated (BDL) and BDL plus N-Lac. Four weeks after surgery, ventricular level of galectin-3, collagen I and III ratio, tumor necrosis factor alpha (TNFα), and brain natriuretic peptide (BNP) were measured either by Western blots or immunohistochemistry or enzyme-linked immunosorbent assay. Blood pressure was measured by polygraph recorder. Cardiomyocyte contractility was measured by inverted microscopy. Results: Galectin-3 and collagen I/III ratio were significantly increased in cirrhotic hearts. TNFα and BNP were significantly increased in BDL serum and heart compared with sham controls. Galectin-3 inhibitor significantly decreased galectin-3, TNFα, and BNP in cirrhotic hearts but not in sham controls. N-Lac also significantly improved the blood pressure, and systolic and diastolic cardiomyocyte contractility in cirrhotic rats but had no effect on sham controls. Conclusion Increased galectin-3 in the cirrhotic heart significantly inhibited contractility via TNFα. Inhibition of galectin-3 decreased the cardiac content of TNFα and BNP and reversed the decreased blood pressure and depressed contractility in the cirrhotic heart. Galectin-3 appears to play a pathogenic role in cirrhotic cardiomyopathy.

Background: The International Hip Outcome Tool 12 (iHOT12), which is now widely adopted in clinical settings, has been established as reliable, valid, and responsive, positioning as a critical evaluation tool globally to gauge the efficacy of hip arthroscopy.This study aimed to translate the iHOT12 questionnaire into Korean and assess its feasibility, internal consistency, and validity concerning the psychometric properties of the Korean version of iHOT12 (iHOT12-K). Methods: The iHOT12 questionnaire was translated into Korean and adapted culturally, following international guidelines, involving forward translation, back-translation, and reconciliation by bilingual experts to ensure cross-cultural equivalence. A cohort of 67 patients diagnosed with femoroacetabular impingement and scheduled for hip arthroscopy between November 2015 and February 2021 participated in assessing the psychometric properties of the iHOT12-K, alongside standardized questionnaires (Korean iterations of the Short Form-36 [SF-36], Hip Disability and Osteoarthritis Outcome Score [HOOS], Korean version of Hip Outcome Score [HOS-K], and modified Harris Hip Score [mHHS]). Psychometric evaluations focusing on feasibility, internal consistency (Cronbach's alpha), and convergent validity (Spearman’s rank correlation) demonstrated the reliability and relevance of iHOT12-K. Results: In the psychometric evaluation of the adapted version, 67 participants (38 men and 29 women; median age, 41 years) were enrolled, with 59 completing the iHOT12-K. The questionnaire showed excellent internal consistency (Cronbach’s alpha, 0.896) without floor or ceiling effects, indicating good feasibility. Strong convergent validity was noted between the iHOT12-K and various hip-specific questionnaires (HOOS, HOS-K, and mHHS), except for the maximal visual analog scale score, demonstrating the reliability and applicability of the iHOT12-K for clinical assessments in Korea. Conclusions The iHOT12-K has successfully undergone transcultural adaptation, demonstrating significant feasibility, internal consistency, and validity. It has been validated for use among Korean-speaking patients undergoing hip arthroscopy, proving to be a valuable tool for clinical assessments.
