The time course of recovery in vestibular neuritis varies between individuals. The aim of this study was to identify the predictors for the early or late recovery of vestibular neuritis. The inclusion criteria were patients 1) who had an acute onset of vertigo lasting at least 24 hours, 2) with a horizontal-torsional unidirectional spontaneous nystagmus, and 3) with a canal paresis of 20% or more on the bithermal caloric tests. The primary endpoint for this study was an early or late recovery of vestibular neuritis as a dependent variable. A functional level scale was used to define the late recovery (5 or more points) at seven days after the symptom onset. The secondary endpoint was the duration of hospitalization. One hundred twenty eight patients met the inclusion criteria for this study, and among them, 71 patients had an early recovery. Multiple logistic regression analysis showed that diabetes mellitus was the only independent significant variable for the prediction of a late recovery of vestibular neuritis. In addition, the diabetes mellitus was a predicting variable for long duration of hospitalization. Diabetes mellitus was a predictor for a late recovery of vestibular neuritis.

Scars on anterior chest after operative correction of funnel chest have been the challenging problem despite introduction of refined techiniques by numerous authors. From December 1996 to September 1998, the authors have performed prefabricated silicone implant insertion in eight female patients presenting funnel chest, using transaxillary approaches instead of substernal or inframammary incisions. In two of eight patients, augmentation mammaplasty was performed simultaneously. Except one case of seroma occurred in early stages, all eight cases of pectus excavatum were satisfactorily reconstructed by this technique. All eight patients expressed their satisfaction with the results during the follow-up visits made between 3 months and 3 years. In conclusion, endoscopic transaxillary approach for the scarless anterior chest can be useful technique in aesthetic correction of the funnel chest.

There is a great public concern that higher consumption of eggs may increase the risk of chronic disease due to high levels of cholesterol in eggs. In contrast to this concern, limited studies have examined this relationship, and the study results have been inconsistent. This study was to evaluate the cross-sectional associations between egg consumption, blood markers and metabolic syndrome in Korean adults. We analyzed data from the combined 2007-2008 Korean National Health and Nutrition Examination Survey (KNHANES). Egg intakes were assessed using a food frequency questionnaire. Metabolic syndrome was ascertained using criteria of the NCEP ATP III (2001) and abdominal obesity criteria of the WHO. In 5,548 subjects, 937 subjects were defined as having metabolic syndrome. In linear regression models, subjects reporting one or more egg consumption per day had significantly lower levels of triglyceride, fasting blood glucose and blood pressure, and a higher level of HDL cholesterol, compared to those who rarely consumed eggs (P-trends < 0.05). After adjustments for potential confounding factors, the associations were no longer significant except for total cholesterol, showing higher levels with frequent egg consumption. More frequent intakes of egg (1 egg or more/day) were associated with lower risk of metabolic syndrome in a logistic regression model (OR: 0.69, 95% CI: 0.50-0.96), but this association also became insignificant after adjustments for multiple confounding factors (OR: 1.05, 95% CI: 0.71-1.57). In healthy Korean adults, frequent intakes of eggs did not adversely affect the risk of metabolic syndrome. Further studies are needed to confirm this finding.

Purpose: We compared visual field progression among patients with primary open-angle glaucoma (POAG), normal tension glaucoma (NTG), and primary angle-closure glaucoma (PACG). Methods: A total of 115 POAG, 123 NTG, and 92 PACG eyes were retrospectively analyzed. Global VF progression was evaluated by calculating the changes of mean deviations. To examine local VF deterioration, scotoma enlargement and deepening were analyzed in the superior, and inferior arcuate, and the central, zones. Results: The mean global rate of change in POAG eyes was -0.52 ± 0.74 dB/year, and -0.35 ± 0.41, and -0.38 ± 0.45 dB/year in NTG and PACG eyes; POAG eyes showed significantly more rapid progression than NTG and PACG eyes (p < 0.01). The superior arcuate zone of POAG eyes, the central zone of NTG eyes, and the inferior arcuate zone of PACG eyes exhibited more scotoma enlargement and scotoma deepening than did other zones. Conclusions The superior arcuate zone of POAG eyes, the central zone of NTG eyes, and the inferior arcuate zone of PACG eyes showed greater VF progression.

Purpose: We report a patient diagnosed with corneal keloid who had laser-assisted in-situ keratomileusis (LASIK).Case summary: A 41-year-old female presented with LASIK 15 years ago. Seven years later, she presented with a growing white corneal mass located in the lower periphery of the right cornea. The best-corrected visual acuity was 0.6 in the right eye and 0.7 in the left eye, and the white lesion was observed in the right cornea at the 5 o’clock position. Anterior segment optical coherence tomography revealed that the mass was invaded by the upper stroma and epithelium, and Bowmans’s membrane was destroyed. Histopathologic examination showed fusiform fibroblasts and disorganized collagen. Taken together, these findings suggested corneal keloids. Conclusions Corneal keloids is a rare disease that develops, sometimes, after LASIK surgery. Although there have been cases of this reported in the literature, there had yet to be a case of LASIK-induced corneal keloids in Korea until this study, reported here.

Background: Blepharitis, a chronic inflammatory condition of the eyelid margin, can cause significant discomfort and impair the quality of life. While traditional treatments like eyelid hygiene and medications are often insufficient, non-invasive therapies such as micro-vibration devices are gaining popularity despite minimal empirical validation. This study evaluated the efficacy and safety of a commercially available microvibration device in a rat model of blepharitis. Methods: Blepharitis was induced in rats using complete Freund’s adjuvant injections. The treatment groups included micro-vibration (180 Hz), micro-vibration with thermal enhancement, and pharmacological interventions with cyclosporine or hyaluronic acid. Ocular signs, including tear break-up time (TBUT), fluorescein staining, eyelid swelling, and telangiectasia, were assessed weekly. Immunohistochemical analysis quantified inflammatory cytokines (interleukin [IL]-1β, IL-6, and tumor necrosis factor-α) in ocular tissues. Results: The micro-vibration therapy significantly improved TBUT, reduced eyelid swelling, and lowered inflammatory cytokine levels. Combining thermal therapy with micro-vibration yielded enhanced antiinflammatory effects, though uncontrolled heating caused tissue damage. Pharmacological treatments were effective but less comprehensive compared to micro-vibration therapies. Conclusion Micro-vibration therapy at 180 Hz demonstrated substantial efficacy in alleviating symptoms of blepharitis and reducing inflammation. However, the uncontrolled thermal function of the device posed safety concerns, emphasizing the need for stringent regulation and parameter control in commercially available devices. This study highlights the potential of micro-vibration therapy as a non-invasive treatment for blepharitis while underscoring the importance of device safety.
