The choice of operative procedures was determined by many factors, but the levator function is considered as the most important factor. Fox recommended that when the levator function was 2 to 9 mm, the patient should be treated by the levator resection and when the levator function was below 2 mm, the patient should be crated by frontalis suspension. But Collin recommended that when the levator function was below 4 mm, the brow suspension procedure got the better result. Beside that, many other authors recommended various opinions. Therefore, when levator function of the patients was between 2 and 4 mm, the choice of operative procedure was much confusing us. The aim of this study is to clarify which is better Procedures between levator resection and the frontalis transfer or orbicularis oculi muscle transfer among the patients with 2 to 4 mm of levator action. From Jan. of 1991 to Dec. of 1994, among 26 patients with 2 to 4 mm levator function, 13 cases of 10 patients were operated by levator resection, 21 cases of 16 patients were teated by frontalis transfer or orbicularis oculi muscle flap. The results were evaluated with the average 27 months of follow-up and we compared the result of the levator resection procedure with that of frontalis muscle transfer or orbicularis oculi muscle transfer. The preoperative average amount of ptosis is about 2.7 mm in cases with levator resection, about 4.0 mm in cases with frontalis muscle transfer or orbicularis oculi muscle flap transfer. The postoperative average amount of ptosis is about 1.7 mm in cases with levator resection about 2.14 mm in cases with frontail muscle transfer or orbicularis oculi muscle flap transfer and so the postoperative improvement of amount of ptosis is about 1.0 mm in cases with levator resection, about 1.86 mm in cases with frontails muscle transfer or orbicularis oculi muscle flap transfer. The major complication of levator resection method is undercorrection. However, the eyelid deformity due to excessive upward traction was more frequent in frontalis muscle flap technique.

2.Clinical Analysis of Staphylococcus aureus Keratitis according to Methicillin-resistance.
Journal of the Korean Ophthalmological Society 2017;58(8):885-895
PURPOSE: This study analyzed clinical characteristics of Staphylococcus aureus keratitis according to methicillin-resistance. METHODS: The authors performed a retrospective chart review of 46 isolates in 46 eyes with Staphylococcus aureus keratitis that were followed up for more than 2 months between January 1998 and December 2014. Comparative analyses of the epidemiology, predisposing factors, initial clinical manifestations, antibiotics susceptibility and clinical outcome between methicillin-resistant Staphylococcus aureus (MRSA) keratitis and methicillin-sensitive Staphylococcus aureus (MSSA) keratitis were performed. Risk factors of poor visual outcome were analyzed using logistic regression analysis. RESULTS: Among 46 eyes, MRSA was present in 15 eyes (33%) and MSSA in 31 eyes (67%). Male (61%) and older than 60 year-old group (48%) were common. Ocular surface disease/ocular surgery history and trauma were more common as a predisposing factor. Vancomycin was 100% sensitive to both the MRSA and MSSA groups. Antibiotics susceptibility to MRSA was significantly low in the oxacillin (0%), gentamicin (13.3%) and trimethoprim/sulfamethoxazole (53.3%) groups. Sensitivity to fluoroquinolone was 81.3% (MRSA 64.3% vs. MSSA 94.4%; p = 0.064). There were no differences in early corneal findings between the groups. The ratio of BCVA 0.5 or more was 24.4% initially and increased to 44.4% after treatment among all eyes (p = 0.046). Risk factors for poor visual outcomes included a BCVA less than 0.1 at initial evaluation (p = 0.033). CONCLUSIONS: Among eyes with Staphylococcus aureus keratitis, 33% were MRSA. The ratio of BCVA 0.5 or more increased after treatment among all eyes. There were no differences between MRSA and MSSA eyes in terms of epidemiology, predisposing factors, initial clinical manifestations or clinical outcome, except for antibiotic susceptibility. For positive patient outcomes, a treatment approach considering methicillin-resistance as well as various factors affecting clinical course is recommended.

Purpose:
To evaluate the effects and limitations of lacrimal endoscopy without silicone tube intubation in patients with epiphora.
Methods:
We conducted a retrospective chart review of 64 eyes in 49 patients who underwent lacrimal endoscopy between May 2021 and May 2022. The clinical characteristics, irrigation test results, lacrimal endoscopic findings, and type of surgery were analyzed.
Results:
The mean duration of symptoms was 31.2 months, and was significantly longer in the failure group than in the success group (p = 0.043). Irrigation tests showed passage, partial obstruction, and complete obstruction in 20 (31.3%), 16 (25.0%), and 28 (43.7%) eyes, respectively. Lacrimal endoscopy showed narrowing, mucus, fibrosis, granulation, and stones in 41 (64.0%), 12 (18.8%), 6 (9.3%), 3 (4.7%), and 2 (3.1%) eyes, respectively. Following lacrimal endoscopy, 32 (50.0%) eyes each were included in the success and failure groups. Preoperative irrigation test results did not affect the success rate (p = 0.203). Silicone tube intubation and dacryocystorhinostomy were performed in 5 (7.8%) and 8 (12.5%) eyes, respectively, because the symptoms did not improve after lacrimal endoscopy.
Conclusions
Lacrimal endoscopy, performed without silicone tube intubation, was effective in improving symptoms and may guide the choice of surgical technique, if required.

PURPOSE: To report a patient with ocular syphilis, who showed variable ocular manifestations, including optic neuritis and chorioretinitis in both eyes over a short time period. CASE SUMMARY: A 44-year-male visited our clinic for central scotoma in the left eye. The visual acuity was 20/25 in the right eye and 20/40 in the left eye. The fundus of the left eye showed a slightly hyperemic optic disc and multiple yellowish deposits. One week later, visual acuity and fundus lesion improved to 20/20 without a definitive treatment. However, 1 month later, he reported a new deterioration of vision in his right eye to 20/40. The right eye had a relative afferent pupillary defect and the fundus examination showed a blurred optic disc margin. Serological work-up was recommended but the patient refused. He returned 3 weeks later with an improvement in the right eye vision (20/25) and a worsening in the left eye (20/200). The examination revealed an improvement of the previously blurred disc margin in the right eye and newly developed chorioretinitis with vasculitis in the left eye. A serological test was performed. The venereal diseases research laboratory titer was 1:32. The fluorescent treponemal antigen absorbance test as positive for IgG and IgM. He was diagnosed with ocular syphilis and referred to the infectious disease department. He was treated with antibiotics. Six months later, the visual acuity was 20/20 in both eyes and the previous fundus lesions had disappeared. CONCLUSIONS: Ocular syphilis should be considered in patients with atypical and variable clinical course.

BACKGROUND/AIMS: Planned endoscopic submucosal dissection with snaring (ESD-S) is thought to shorten operating time spent on submucosal dissection, but may lead to uncertainty of en bloc resection or to a possible increase in tumor-positive margins. The purpose of the present study is to investigate the feasibility of ESD-S as a planned procedure for gastric adenoma. MATERIALS AND METHODS: The medical records of 99 patients who underwent ESD-S or ESD for gastric adenoma between May 2011 and May 2012 were retrospectively reviewed. We analyzed the differences between the ESD-S and the ESD groups, focusing on rates of en bloc resection and pathologic complete resection, mean operation time, and complications. RESULTS: The mean operation time was significantly lower in the ESD-S group than in the ESD group (19.9+/-11.2 vs. 33.8+/-19.9, P=0.012). Cases with an operation time under 30 minutes were more frequent in the ESD-S group (88.9% vs. 48.1%, OR=8.615, 95% CI=2.949~25.168). There were no significant differences in en bloc resection, histologic complete resection, or complication rates between the two groups. CONCLUSIONS: ESD-S has a time advantage over ESD with a comparable compete resection rate. ESD-S can be considered a planned method for available early gastric adenoma.

Journal of the Korean Ophthalmological Society 2008;49(6):925-934
PURPOSE: To evaluate the efficacy of trabeculectomy using modified scleral flap suture technique METHODS: We retrospectively reviewed the medical records of 52 patients (55 eyes) who had undergone trabeculectomy from January 2003 to January 2007. Standard trabeculectomy was performed for 29 eyes of 27 patients, modified trabeculectomy for 26 eyes of 25 patients. We changed suture site of scleral flap corner about 1mm medially from original site and added tight suture to both lateral margins of scleral flap to prevent overflow in modified group. In both groups, most of patients were injected 0.1 ml of 0.02 mg/ml mitomycin-C (MMC) subconjunctivally and the others 0.1 ml of 0.04 mg/ml MMC. We evaluated intraocular pressure (IOP), complication, morphology of filtering bleb, cumulative success rates. RESULTS: Argon laser suturelysis was performed postoperatively in about half cases of both groups. The IOPs of modified group were consistently lower than those of standard group for 24 months except postoperative 1 day and 1 week. There was a significant difference of IOP at postoperative 2 months and 12 months (p<0.05). No significant difference of complications was found between two groups. The diffuse bleb with microcyst was found in 19 eyes (73%) of modified group and 17 eyes (59%) of standard group. From Kaplan-Meier survival analysis, cumulative success rates of modified group were higher than those of standard group (p<0.05). CONCLUSIONS: Trabeculectomy using modified scleral flap suture appears to give better IOP control than standard trabeculectomy.

OBJECTIVE: Heat therapy is one of physical therapies used most commonly in chronic osteoarthritis. The therapeutic effects of heat therapy might be attributed to induce heat shock proteins in heat-stimulated cells and tissues and therefore, to inhibit cellular damages due to inflammation. In order to investigate preliminarily the therapeutic effects of heat therapy, Hsp(heat shock protein) 70 expressions by heat stimulation were measured in cultured chondrocytes and knee joint cartilages of rabbits. METHOD: Five rabbits were used in total in this study. Three rabbits were used for chodrocytes culture and two rabbits were in vivo study. Chondrocytes were cultured from knee cartilages of three rabbits and treated at 33degreesC, 37degreesC, and 42degreesC for 20 min. In order to clarify whether heat therapy using ultrasonification can induce Hsp 70 expression in cartilage tissues, right knees of rabbits were heat-stimulated by ultrasonification for 20 min and their left knees were untreated. After 2 hours, cultured chondrocytes and cartilages were prepared and Hsp 70 expression was also observed by Western blot analysis. RESULTS: Hsp 70 expression was increased 1.48 folds in 42degreesC treated cells compared to in 37degreesC treated cells. The heat-stimulated cartilages showed 1.65 fold increases in Hsp 70 expression compared to the unstimulated cartilages. CONCLUSION: Hsp 70 expressions were increased by heat stimulation in cultured chondrocytes as well as in cartilage issues.

PURPOSE: To establish the basis for a non-invasive and non-destructive assessment of the mechanical properties during natural fracture healing by analyzing the vibrational property of the fracture healing and comparing the vibrational property, the bone healing status (as determined by X-ray) and the mechanical strength parameters. MATERIALS AND METHODS: The tibial shafts of rabbits were broken under general anesthesia. The rabbits were sacrificed at 2, 4, 6 weeks after the fracture, then X-rays of the fractured tibias were sequentially taken to detect the fracture healing. The vibration mode and the biomechanical strength were measured. RESULTS: According to the results of a multiple regression analysis, the standardized coefficients of callus, apposition, lateral angulation, DAMP1, FREQ1 in the fractured tibias, were -0.80, -0.23, -0.21, -0.25, -0.25. In normal contralateral tibias, the standardized coefficients of the area, FREQ1, DAMP1, FREQ2, DAMP3 were -0.73, 0.28, 0.41, 0.39, -0.25. CONCLUSION: A monitoring of the fracture healing process that utilizes the frequency response function is thought to be useful in detecting the early phase of healing within 4 weeks. Additional studies on the vibrational characteristics of the healing bones after a clinical union or after simillar pathologies should be pursued so that future diagnostic applications ca be made.

We report a patient with reactive arthritis induced by recent streptococcal infection. A 27 year man had suffered from fever, sore throat and pain on left sternoclavicular joint. Arthritis occurred two days after tonsillitis and involved left sternoclavicular joint. Left sternoclavicular joint showed redness, swelling and tenderness. There were no growth of microorganism in blood cultures, no evidence of group Abeta-streptococcus in throat cultures, but antistreptolysin-O (ASO) and c-reactive protein (CRP) serum titers were elevated in sequential monitoring. Bone scan showed focal hot uptake at left sternoclavicular joint and Gallium scan showed diffuse inflammation at left sternoclavicular joint and soft tissue biopsy around sternoclavicular joint showed mild chronic inflammation. We suspected septic arthritis and prescribed empirical antibiotics but his symptoms were wax and wane. From the poor responsiveness to antibiotics, sustained high titers of ASO and recent history of tonsillitis, we confirmed poststreptococcal reactive arthritis, and attempted high-dose anti-inflammatory drug (aspirin 6 gram). Left sternoclavicular and shoulder pain improved.
