The committee of admitted doctors developed a questionnaire regarding medical dispute and distributed it to 1,600 members of Korean Academy of Orthodontics. The questionnaire consisted of three categories and 56 items covering basic information about the doctors and patients who had experienced medical disputes, the cause and workaround of medical accidents, and methods for taking precautions. The present survey showed a similar proportion of responders who had experienced a medical accident compared to the study in 1997. The primary reason for medical disputes was dissatisfaction with appearance. Many doctors felt that they would likely experience a medical dispute at some point. Most disputes were settled by doctors themselves, usually for an amount of less than 5 million Korean won. For some doctors, medical accidents lead to ongoing psychological problems. Responders felt that continuing education for medical dispute is very necessary. These results reveal a need for the association of orthodontists to lead advancements in education and countermeasures for preventing and managing medical accidents and disputes.

Limb salvage operations for osteosarcoma of the extremity usually consist of wide excision and skeletal reconstruction. Most osteosarcoma patients are anemic prior to the surgery as majority of them undergo preoperative neo-adjuvant chemotherapy; thus, it is necessary to treat anemia before and after the surgery since limb salvage operation tends to accompany significant blood loss. Despite the fact that blood transfusion has bad influence on prognosis, complication, and postoperative outcome of cancer patients, it is still considered as a standard management to fix anemia for limb salvage operations. We would like to present a case report in which the authors succeeded in performing limb salvage operations on patients with distal femur osteosarcoma without transfusion.

PURPOSE: To investigate the correlation between optic disc size and retinal nerve fiber layer (RNFL) thickness in healthy subjects and patients with normal tension glaucoma (NTG). METHODS: Optical coherence tomography was performed on 50 eyes of 50 healthy subjects and on 50 eyes of 50 NTG patients. RESULTS: The optic disc size showed a significant correlation with the RNFL thickness in healthy subjects and in patients with NTG. Significant correlations were observed between the optic disc size and the ratio of superior-to-total RNFL thickness (r=-0.283, p=0.049) and the ratio of nasal to total RNFL thickness (r=0.403, p=0.004) in healthy subjects. In patients with NTG, significant correlations were observed between the optic disc size and the ratio of superior to total RNFL thickness (r=-0.314, p=0.029) and the ratio of inferior to total RNFL thickness (r=-0.302, p=0.034). CONCLUSIONS: RNFL thickness increased significantly with an increase in optic disc size in both healthy subjects and NTG patients. The correlation between optic disc size and the ratios of each quadrant to the total RNFL thickness showed a different pattern between healthy subjects and NTG patients.

PURPOSE: To investigate the frequency and characteristics of artifacts which can cause errors in retinal nerve fiber layer nalysis using optical coherence tomography (OCT). METHODS: The frequency, characteristics and retinal lesions responsible for the artifact were analyzed for 179 patients (338 eyes) by OCT. All images were categorized into two groups according to the presence of artifacts and then, the differences between the two groups were analyzed by t-test and cross-tabulation analysis in terms of age, refractive error, peripapillary atrophic areas, and type of glaucoma. RESULTS: The male to female ratio was 1.37:1, average age was 47.6+/-15.7 years and average degree of refraction was -1.78+/-0.23 diopter. Artifacts were noted in 64 eyes (18.9%), and were present in the temporal quadrant in 12 eyes (18.8%), superior quadrant in 51 eyes (79.7%), nasal quadrant in 19 eyes (87.5%), and inferior quadrant in 8 eyes (48.4%). The average angle of the artifact was 138 degrees. Although retinal lesion, age, and glaucoma type were not significantly different between the two groups, peripapillary atrophy and myopia were significantly more common in the group with the artifact. CONCLUSIONS: When analyzing retinal nerve fiber layer by OCT, artifacts should be considered, especially in cases of peripapillary atrophy and myopia.
