To determine the usefulness of MR axial images for diagnosis ACL tears, we reviewed MRIs of 67 patients with ACL tear confirmed by arthroscopic examination, retrospectively. There were 53 acute and 14 chronic tears. The axial MR images had a 97% sensitivity(acute: 96%, chronic: 100%). Findings of acute ACL tears on sequential axial imaging could be categorized as 1) diffuse swelling with abnormal substance signal in 14 cases(27.5%), 2) focal bulging or irregularity of medial border in 11 cases(21.6%) or 3) combination of the two in 26 cases(50.9%). Findings of chronic ACL tears also could be categorized as abnormally irregular thin fibers in 6 cases(42.9%) or nonvisualization(empty lateral wall) in 8 cases(57.1%). We concluded that MR axial images could provide additional useful information in the diagnosis of ACL tear.

OBJECTIVES: We investigated the operation needs of school meal support centers (SMSC) in Chungnam-do based on analysis of nutrition teachers' perception of them. METHODS: The Chungnam government established the first SMSC in 2012. Thirteen SMSCs are currently being operated in Chungnam-do. To analyze the results quantitatively, we investigated nutrition teachers opinions regarding the necessity for SMSCs as a dependent variable and derived the independent variables based on the causal relationships with dependent variables using the ordered logit model. Those independent variables included region, school type, number of students, attitude regarding free meal policy, satisfaction with school meal policy, and preference for local food. RESULTS: Briefly, teachers in the region in which the SMSC was located more strongly supported the SMSC. In addition, teachers in public schools with a smaller number of students believed that having a SMSC is more beneficial, and that other variables also affected the necessity for SMSCs. Moreover, nutrition teachers preferred local foods rather than organic foods because of the unstable supply of organic foods. CONCLUSIONS: Based on the results of this study, it was recommended that the local government implement the policy consistently. Moreover, it was recommended that the government operate the SMSC more efficiently, enhance the roles of the SMSC as the local organization responsible for student nutritional planing and expand the coverage of agricultural products.

Floating-Harbor syndrome (FHS) is a rare genetic disorder. This report introduced in a patient with FHS. Distinctive facial characteristics, severe skeletal class 3 malocclusion with underdeveloped maxilla and protruded mandible, congenital missing teeth, microdontia and ectopic positions of maxillary teeth were presented in the patient. In his twin sister, mild skeletal class 3 malocclusion with protruded mandible was observed but congenital missing teeth and microdontia were not observed. High-arched palate, narrow V-shaped maxillary arch compared to wide and ovoid mandibular arch and inverse relationship between the maxillary and mandibular intermolar width resulted in posterior crossbite were confirmed by model analysis of the patient. These were not observed in the twins. Behaviorally, poor cooperation during dental treatment because of mental retardation was observed in the patient.

The purpose of this study was to analyze treatment methods, results, timings and clinical signs and symptoms in failed cases of each treatment method of dens evaginatus on the premolar areas. In this study, 151 patients and 417 teeth were included. Resin restoration and direct pulp capping as preventive treatment and pulp revascularization, apexification and conventional endodontic treatment as endodontic treatment were included for treatment methods. In the preventive resin restoration, successful results were shown in the intact tubercles and also effective when the tubercles were fractured. In the direct pulp capping, resolved clinical symptoms and growth of the roots were shown when there was only pain during chewing without apical lesion. Apical lesion was the most common pretreatment signs and symptoms of the pulp revascularization, apexification and conventional endodontic treatment. In the pulp revascularization, successful results was obtained in most cases. But in some cases, root length or root wall thickness was not increased. Effective results were shown both of the apexification and conventional endodontic treatment. In order to increase success rate of preventive treatment of dens evaginatus, resin restoration was required to be done when tubercle did not occluded or in the presence of intact tubercles. When tubercle was fractured, root development stage and pulp condition should be considered for successful treatment.

Purpose: To evaluate the clinical efficacy of amniotic membrane extract eye drops (AMEEDs) in patients with persistent epithelial defects (PEDs) of the cornea. Methods: Sixteen patients with PEDs refractory to the conventional treatment were further treated with AMEEDs six times a day. Visual acuity, visual analog scale (VAS), esthesiometer score, and areas of the epithelial defects before and after 1 and 2 months of treatment were evaluated. After 2 months, AMEEDs were considered effective if all epithelial defects were healed, partially effective if the epithelial defects decreased in size compared with the baseline, and ineffective if the epithelial defects increased in size and required additional treatment. Results: After 2 months of treatment with AMEEDs, there was a reduction in the area of epithelial defects (5.2 ± 3.1 mm2 vs. 0.1 ± 0.1 mm2, respectively, p = 0.01), as well as a significant improvement in best-corrected visual acuity (0.8 ± 0.5 logarithm of minimal angle of resolution [LogMAR] vs. 0.6 ± 0.3 LogMAR, respectively, p = 0.03), and VAS scores (4.3 ± 1.0 vs. 2.8 ± 0.7, respectively, p = 0.04) compared with the baseline values. Treatment with AMEEDs was effective in 13 (81.3%) patients and partially effective in three (18.8%) patients. Conclusions AMEEDs could stimulate epithelial wound healing and improve ocular symptoms in patients with refractory PED. Therefore, AMEEDs could be considered an effective treatment option for refractory PEDs.

Purpose: We evaluated the clinical manifestations of, and risk factors for, infectious keratitis in patients with ocular graft-versus-host disease (GVHD). Methods: A total of 11 patients who developed infectious keratitis after a diagnosis of ocular GVHD between January 2015 and December 2020, and 36 who did not (the control group), were included in this retrospective study. We recorded sex, age, any underlying disease, any other organ affected by systemic GVHD, systemic immunosuppressant use, follow-up duration, clinical manifestations, the severity of ocular GVHD prior to infection, the size of the epithelial defect, the depth of infiltration, hypopyon status, and the results of microbiological tests. Systemic and ocular indices (including systemic GVHD status) were compared using the chi-squared test. Risk factors for infection were identified. Results: Of the corneal indices, the presence of corneal filaments, the extent of corneal neovascularization, and the number of corneal epithelial defects were significantly higher in the infected group (p = 0.023, p = 0.004, and p = 0.001, respectively). GVHD severity was also significantly higher in that group (p < 0.001). The presence of corneal filaments, corneal neovascularization, and corneal epithelial defects prior to infection correlated significantly with the risk of infection (p = 0.046, p = 0.010, and p = 0.003, respectively). Multivariate analysis identified corneal epithelial defects as a significant risk factor for infection (p = 0.029). Conclusions In patients with ocular GVHD, corneal epithelial defects, corneal neovascularization, and corneal filaments prior to infection were associated with the development of infection. In particular, corneal epithelial defects before infection was a significant risk factor for infection.

Purpose: To report a case of acute bilateral corneal edema after inhalation of spray paint.Case summary: A 47-year-old male presented with blurred vision in both eyes 12 hours after inhalation of spray paint. He had no history of ocular surgery or chronic ocular disease. The corrected visual acuity was 20/100 in the right eye and 20/40 in the left eye. An ocular examination revealed diffuse bullous changes in the epithelium and mild stromal edema in the cornea of both eyes. At one week after treatment with topical hypertonic solutions and corticosteroids, the visual acuity had improved to 20/20 and slit-lamp examination showed clear corneas without edema. Conclusions Inhalation of a chemical substance can lead to acute bilateral corneal edema, even without direct contact, but the lesion may resolve rapidly.

Purpose: To evaluate the short-term efficacy and safety of a standardized micropulse transscleral diode laser cyclophotocoagulation (micropulse TS-CPC) procedure in Korean glaucoma patients. Methods: In this retrospective study, the medical records of 19 eyes of 19 patients who were diagnosed with glaucoma, underwent micropulse TS-CPC and were followed for at least 3 months were reviewed. Visual acuity (VA), intraocular pressure (IOP), the number of IOP-lowering eye drops, and the success rate, defined as the percentage of eyes achieving an IOP of 6-21 mmHg with or without medication, or an IOP decrease of ≥20% compared to baseline after the procedure, were evaluated at baseline, 1 week, 1 month and 3 months postoperatively. Results: The mean age was 58.0 years at the time of treatment. Among 19 eyes that were evaluated, two had a previous history of trabeculectomy, two had an Ahmed ® Glaucoma Valve implantation, one had selective laser trabeculoplasty, and four had vitrectomy. Baseline mean IOP was 26.21 ± 5.22 mmHg, which significantly decreased to 17.72 ± 4.25 mmHg at postoperative 3 months (p < 0.001). The success rate at postoperative 3 months was 84.2%. Five eyes experienced postoperative hypotony, and persistent corneal epithelial defects in three eyes were successfully treated with topical medication. Two of 19 eyes had a decrease in VA of unknown cause, and 9 eyes had mydriasis due to paralysis in iris constriction, which did not resolve until 3 months follow-up. Conclusions Micropulse TS-CPC had a relatively good IOP-lowering effect. However, a rather high proportion of patients had complications from a standardized protocol, and this should be considered when performing micropulse TS-CPC in Korean patients.

PURPOSE: The purpose of this study was to investigate stress, depression and health risk behaviors in elderly people. METHODS: The subjects were 238 Korean elders who had visited the convalescent center. The level of stress was measured by the Korean version of BEPSI, which was developed by Bae, Jeung & Yoo (1992) and modified by Yim et al.(1996). CES-D was used to measure the level of depression. For health risk behaviors, we measured cigarette consumption and alcohol drinking during the last one month. RESULTS: Of the subjects, 17.4% were excessive drinkers and 18.9% were currently smokers. The level of stress was between moderate and high, and 62.7% of the subjects were depressed. There were significant differences in stress and depression according to economic status and self-reported health. In addition, depression had positive correlations with stress and QF score. CONCLUSION: Stress and depression management programs for the elderly are needed. These findings indicate that nurses must consider stress and alcohol drinking when they take care of depressed elderly people.
