Vagal mononeuropathy is very rare. Diabetes mellitus is one of the causes of this rare disease condition. Here we report a 44-year-old woman who presented with an idiopathic vagal mononeuropathy and was finally diagnosed with diabetic vagal mononeuropathy. She presented with isolated dysphagia without hoarseness or other symptoms related with vagal dysfunction. Except for diabetes mellitus, no abnormalities were found by routine and specific checkups including brain imaging, gastroscopy, electromyography, and laryngoscopy. Finally, 12 days later, she abruptly developed hoarseness without other cranial nerve dysfunction.We suggest that her neurological symptoms originated from diabetes affecting the vagus nerve in isolation. Clinicians should pay attention to this association, especially when they encounter a patient with diabetes mellitus with sudden idiopathic dysphagia even without problems of vocalization.

Purpose: To evaluate the clinical outcomes of myopic choroidal neovascularization (CNV) and atrophic and tractional changes according to the ATN (A: atrophy, T: traction, N: neovascularization) classification system. Methods: This was a retrospective review of the medical records of myopic CNV patients treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections and followed up for at least 3 years. Atrophic and tractional components were graded according to the ATN system at baseline and the last visit. Results: The study included 21 eyes in 21 patients. The mean age was 52.29 ± 14.6 years, the mean follow-up duration was 57.65 ± 18.8 months, and the mean number of injections was 2.9 ± 1.9. Recurrence occurred in seven eyes (33.3%). Five patients (23.8%) developed myopic CNV in the contralateral eye. The mean initial and final logarithm of the minimum angle of resolution (logMAR) visual acuities were 0.44 ± 0.30 and 0.33 ± 0.39, respectively. Visual acuity was maintained or improved compared to baseline in 15 eyes (71.4%). Baseline visual acuity was significantly associated with the final visual acuity (p = 0.026). Based on the ATN classification system, the atrophic component progressed in four eyes (19.0%), while the tractional component improved in one eye (4.8%) and progressed in five eyes (23.8%). Conclusions Intravitreal anti-VEGF injection therapy effectively preserved long-term vision in myopic CNV patients. Evaluation of the atrophic and tractional components should not be neglected during the follow-up.

PURPOSE: We report a case of bilateral optic neuritis without encephalomyelitis, following measles that has recently spread in our country. METHODS: Nine-year-old male patient diagnosed as measles based on the typical symptoms and serum IgM positivity complained of sudden decrease in visual acuity of both eyes (FC/50 Cm in both eyes). Bilateral afferent pupillary defect were detected and visual evoked potentials show the delayed P100 latency and the decreased amplitude in both eyes. We diagnosed his case as the bilateral optic neuritis and treated with the high dose steroid therapy. RESULTS: At 2 months after visual loss, the afferent pupillary defect disappeared and the visual evoked potentials returned to normal. At 6 month, the visual acuity of the right and left eyes improved to 0.9 and 1.0, respectively. CONCLUSION: Optic neuritis following measles is a rare entity, and it is the first time such a case has been reported in Korea. This is a rare case where optic neuritis occurred without the symptoms or signs of encephalitis. In this study, we diagnosed and treated the first case of optic neuritis following measles in korea, with satisfactory results.

The cataract extraction in vitrectomized proliferative diabetic retinopathy(PDR) may be different from the ordinary non-vitrectomized patients in several points. We tried to know what`s the problems during the operation, how`s the visual outcomes and the postoperative complications in these eyes. In 18 previously vitrectomized PDR patients(25 eyes), we performed the extracapsular cataract extraction(ECCE) in 7 eyes and the phacoemulsification in 18 eyes. The intraoperative problems were insufficient dilation of pupil, unstability of (anterior and posterior) chamber depth, and difficulty in removal of cortex, which is firmly adherent to the posterior lens capsule. Opacity of posterior lens capsule, elevation of intraocular pressure, exudative pupillary membrane, posterior synechia and corneal edema were the major postoperative complications. In 22 eyes(88%), the visual acuity was increased more than 2 lines, Cataract extraction was easier and less postoperative complications these cases.

Hirayama disease usually selectively involves lower cervical myotomes (C8, T1). Thus, patients usually manifest with atrophy and weakness of small hand muscle. Predominant isolated involvement of proximal arm is rarely reported in Hirayama disease. Here, we report a case of Hirayama disease who had focal weakness and wasting, mainly confined to right biceps brachii muscle, with prominent shifting of dural sac in C4-5 segment by dynamic flexion magnetic resonance imaging (dfMRI), which may explain this unusual distribution of the disease.

The present study evaluated the effects of guided tissue regeneration using biodegradable membrane, with and without calcium-phosphate thin film coated deproteinated bone powder in beagle dogs. Contralateral fenestration defects(6 x 4 mm) were created 4 mm apical to the buccal alveolar crest on maxillary canine teeth in 5 beagle dogs. Ca-P thin film coated deproteinated bone powder was implanted into one randomly selected fenestration defect(experimental group). Biodegradable membranes were used to provide bilateral GTR. Tissue blocks including defects with overlying membranes and soft tissues were harvested following a four- & eight-week healing interval and prepared for histologic analysis. The results of this study were as follows. 1. The regeneration of new bone, new periodontal ligament, and new cementum was occurred in experimental group more than control group. 2. The collapse of biodegradable membranes into defects were showed in control group and the space for regeneration was diminished. In experimental group, the space was maintained without collapse by graft materials. 3. In experimental group, the graft materials were resorbed at 4 weeks after surgery and regeneration of bone surrounding graft materials was occurred at 8 weeks after surgery. 4. Biodegradable membranes were not resorbed at 4 weeks and partial resorption was occurred at 8 weeks but the framework and the shape of membranes were maintained. No inflammation was showed at resorption. In conclusion, the results of the present study suggest that Ca-P thin film coated deproteinated bone powder has adjunctive effect to GTR in periodontal fenestration defects. Because it has osteoconductive property and prohibit collapse of membrane into defect, can promote regeneration of much new attachment apparatus.

STATEMENT OF PROBLEM: Many dental clinicians are concerned about immediate loading of inserted implants. However, there have been few clinical studies surveying the success rates of immediate loading, based on Korean implant systems. PURPOSE: The aim of this study was to evaluate the outcome of immediate functional loading of the implant (SinusQuick(TM) EB, Neobiotech Co., Seoul, Korea) in partially edentulous maxilla or mandible. MATERIAL AND METHODS: Total 15 implants were placed. Within 2 weeks after implant insertion, provisional implant-supported fixed partial dentures were delivered to the patients. Quantitatively, marginal bone loss was measured at the time of immediate loading, after 3-months of continued loading and at the last follow-up. The mean follow-up period was 4.8 months. RESULTS: Mean marginal bone loss from implant surgery to early loading, 3-months follow-up and last follow-up was 0.03 +/- 0.07 mm, 0.16 +/- 0.17 mm and 0.29 +/- 0.19 mm. No implant failed up to 6 months after insertion, resulting in a 100% survival rate. CONCLUSION: Immediate loading exhibited high success rate in partial edentulism for up to 6 months. Well-controlled long term clinical studies with large sample size are necessary to confirm this finding.
