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 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.

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 assessed changes in ocular biometrics following Ahmed valve implantation. Methods: We conducted a retrospective analysis involving 76 eyes of 76 glaucoma patients who underwent Ahmed valve implantation; these patients were followed up for 6 months. Preoperative data, including age, intraocular pressure (IOP), refractive status, axial length, central corneal thickness, anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior and posterior keratometry, were evaluated preoperatively and at 1 week, 1 month, and 6 months postoperatively. Results: The mean IOP exhibited a significant reduction from 39.17 ± 14.06 mmHg preoperatively to 11.43 ± 3.25 mmHg (p < 0.001), 13.18 ± 4.64 mmHg (p < 0.001), and 12.95 ± 4.37 mmHg (p < 0.001) at 1 week, 1 month, and 6 months postoperatively, respectively. Furthermore, the axial length exhibited a significant post-surgery reduction, measuring 23.74 ± 2.01 mm preoperatively and 23.48 ± 1.86 mm (p < 0.001), 23.57 ± 1.94 mm (p < 0.001), and 23.61 ± 1.98 mm (p = 0.002) at 1 week, 1 month, and 6 months postoperatively, respectively. However, no significant changes were observed in various other parameters, such as anterior and posterior keratometry, refractive status, ACA, ACD, or ACV, at 6 months post-surgery (p > 0.05). Conclusions Ahmed valve implantation resulted in a significant reduction in axial length. Furthermore, it had transient but non-significant effects on keratometry, refractive status, ACA, ACD, and ACV at 6 months after surgery.
