Purpose: We used optical coherence tomography angiography to analyze the macular microvasculature of normal eyes of healthy Korean children; we derived normative data stratified by age. Methods: We retrospectively analyzed the medical records of 68 children (126 eyes) aged from 3 to 15 years. Optical coherence tomography angiography was performed on 3-mm2 regions centered on the fovea. The vascular densities of the superficial and deep capillary plexuses and the foveal avascular zone were determined, and analyzed by age. We sought correlations between age, gender, axial length, and the spherical equivalent. Results: The foveal, superficial capillary plexus vessel densities were 17.41 ± 5.41, 20.53 ± 4.76, 21.78 ± 5.73, and 22.95 ± 3.91% in children aged 3-5, 6-8, 9-11, and 12-15 years, respectively. The vessel densities of the foveal deep capillary plexus were 30.20 ± 6.59, 34.54 ± 7.16, 35.81 ± 6.02, and 37.38 ± 5.16% in those aged 3-5, 6-8, 9-11, and 12-15 years, respectively. Significant differences by age were apparent (p = 0.002, p < 0.001, respectively). The foveal vessel densities of the superficial and deep capillary plexuses were positively correlated with axial length (R2 = 0.153, p < 0.001; R2 = 0.158, p < 0.001, respectively) and the foveal avascular zone area was negatively correlated with axial length (R2 = 0.085, p < 0.001). Conclusions The vessel densities of the superficial and deep capillary plexuses measured via optical coherence tomography angiography in normal eyes of healthy Korean children differed by age, and correlated significantly with axial length.

BACKGROUND: The purpose of this study was to compare the cost-effectiveness of propofol using a target-controlled infusion (TCI) with two currently used anesthetic regimens during major operations. METHODS: Forty-two patients undergoing major gynecological surgery were divided into three groups according to the period during which the surgeries were performed. Group propofol/TCI (n = 16) received 1% propofol using TCI-50% N2O, Group isoflurane (n = 14) received thiopental 5 mg/kg-isoflurane-50% N2O, and Group enflurane (n = 12) received thiopental 5 mg/kg-enflurane-50% N2O. All patients also received 2 microgram/kg of fentanyl before induction. Concentrations of propofol and volatile anesthetics were varied according to the patient's hemodynamic responses. Consumption of volatile anesthetics was measured by weighing the vaporizers by a precision weighing machine. RESULTS: Biometric data, duration of surgery and of anesthesia were similar in the three groups. Recovery from anesthesia was significantly shorter in the propofol/TCI group. Episodes of postoperative nausea and vomiting in the recovery room were less common in propofol/TCI group. Patient satisfaction was similar in all three groups. Total (intra- and postoperative) costs were significantly higher in the propofol/TCI group. CONCLUSIONS: When compared with the standard anesthetic regimens, the use of propofol using TCI anesthesia during major operations was associated with higher costs, but did not offer any clinically significant advantages in cost-effectiveness over the standard anesthesia regimens.

PURPOSE: To present a new classification based on the CT and MR imaging findings of buccal space lesions, and to propose guidelines for their radiologic differentiation. MATERIALS AND METHODS: Sixty-two histopathologically confirmed or clinically diagnosed buccal space lesions were classified on the basis of their morphologic appearance and extension to adjacent space as either (1) a mass with a distinct margin, confined to the buccal space; (2) a mass with surrounding infiltration, confined to the buccal space; or (3) a multi-space occupying mass. RESULTS: Type 1 included pleomorphic adenoma, ex-pleomorphic adenoma, carcinoma, B-cell lymphoma, acinic cell carcinoma, rhabdomyosarcoma, glomus tumor and ameloblastoma, and differentiation between malignant and benign neoplasms was not possible. Type 2 included adenoid cystic carcinoma, abscess, complicated dermoid cyst, and Kimura disease. T-cell lymphoma, neurofibroma, vascular malformation, inflammation, and foreign body granuloma pertained to type 3, and each type-3 entity showed different imaging characteristics. CONCLUSION: This new classification based on CT and MR imaging characteristics may provide useful guidelines for predicting the differential diagnosis of buccal space lesions.

PURPOSE: To evaluate the relationship between radiographic parameters and clinical results after operative treatment of the displaced intra-articular calcaneal fractures. MATERIALS AND METHODS: We analyzed 35 patients of unilateral displaced intraarticular calcaneal fractures who had operative treatment with minimum follow up of 1 year. At the last follow up, we measured the radiographic parameters including Bohler angle, Gissane angle, heel height, calcaneal length, talocalcaneal angle, talar declination angle, subtalar incongruity between normal and affected site. Clinical results were measured by Creighton-Nebraska Health Foundation Assessment Score (CNH). The correlation between the radiographic parameters and the clinical results were analysed by Pearson correlation method. RESULTS: Among the all radiographic parameters we analyzed, only subtalar incongruity shows strong negative linear correlation with clinical results. The average difference of subtalar incongruity between normal and affected site was 0.54 mm (0~2.5) and the correlation coefficients with CNH score was -0.784 (p=0.002). CONCLUSION: We suggest that the subtalar incongruity is significantly correlated with the clinical results after operative treatment of the displaced intraarticular calcaneal fractures.

PURPOSE: Retrograde intramedullary nailing has been recommended as one of the treatment options for the distal femoral fracture, particularly in patients who are obese, are pregnant, has sustained ipsilateral femoral neck fracture, have multiple injuries. However there are some disadvantage such as post-arthrotomy infection, knee joint stiffness. This paper is to evaluate the result and complication of treatment of distal femoral fracture with a retrograde intramedullary nailing. MATERIALS AND METHODS: We reviewed 13 cases (distal femoral shaft fracture: 6 cases, supracondylar fracture: 7 cases) of the distal femoral fracture who had been treated with retrograde intramedullary nailing and follow up for more than 12 months from January 1999 to December 2001. The rate of bony union, range of motion of the knee, complications were evaluated. RESULTS: The mean duration of bony union was 20 weeks (range, 16~25 weeks). A case of delayed union was developed. In 4 cases of 13 cases showed posterior angulation below 6 degree, which did not need further treatment. According to Saunder's criteria, excellent result was achieved in 8 patients, good result in 5 patients, respectively. CONCLUSION: This study showed good clinical and radiological results of union with retrograde intramedullary nailing at the distal femoral fracture and ipsilateral multiple fracture

PURPOSE: This study compares the clinical results of open reduction and internal fixation with and without bone graft for the treatment of intra-articular calcaneal fractures. MATERIALS AND METHODS: Twenty-five patients who had open reduction and internal fixation for intra-articular calcaneal fractures and available for at least 1 year of follow-up were included in this study. Fifteen cases were operated with bone graft. Period to bone union and functional evaluation score were compared between both groups with analysis of complications. RESULTS: Bone union was achieved in all cases with average bone union time of 11.6 weeks and 12.8 weeks in group with and without bone graft respectively. Creighton-Nebraska Health Foundation (CNHF) functional score was 86.5 points and 80.3 points respectively. The period to bone union and the CNHF score in the comparison of two groups were statistically insignificant. Complications were observed in four cases of group without bone graft and 5 cases of group with bone graft. CONCLUSION: This study indicates that bone graft does not play a significant role in bone union and functional outcome when intra-articular calcaneal fractures are treated with open reduction and internal fixation.

Internal myiasis is a rare disease, which has not been reported in Korea, yet. This case report describes a patient with pneumonia associated with internal myiasis. She was 84-year old female who was admitted to the emergency department, Konyang University Hospital as a result of dyspnea and fever and a drowsy mental state. Approximately twenty fly maggots continuously crawled out from the nose at the third hospital day in the intensive care unit. These maggots were almost 7.2mm long and were identified as the genus lucilia belonging to the family Calliphoridae. In addition, a bronchial washing study showed eggs of the dipterous larvae. A lesion of this myiasis case might have been located in the respiratory system of patient. This case is the first internal myiasis of the respiratory system reported in Korea. This cases is discussed with a review of the relevant literature.

PURPOSE: This study is to analysis the outcome of patient with surgically treated Maisonneuve fracture and find out the factors that might influence the outcome. MATERIAL AND METHODS: 20 patients who had surgical treatment due to Maisonneuve fracture between February, 2001 to March, 2005 were studied. The patients were followed for at least 1 year and average follow up period was 25 months. The average age was 41 years, 16 were male and 4 were female. Mechanism of injury according to Rouge- Hansen classification was supination-external rotation. In all cases, percutaneous screw fixation was applied proximal to tibiofibular syndesmosis. The screws were removed after 8 weeks under local anesthesis. Clinical, functional and radiographic results were evaluated. RESULTS: 17 cases (85%) showed satisfying clinical and radiographic results. The mean functional score according to Ankle Scoring System was 91 (83 to 95). Complication occurred in 1 case with underlying systemic disease and 2 cases with initial ankle joint dislocation. CONCLUSION: Surgical treatment of Maisonneuve fracture showed relatively satisfying result. However, initial injury state and accompanying disease seem to have great effect on the result.

Coronary artery anomalies are diagnosed in 0.6 to 1.5% of patients who undergo coronary angiography (CAG). They may present with life threatening conditions but are generally asymptomatic. Recognition and adequate visualization of the anomaly is essential for correct management of the condition. However, in some cases the exact orifice and course of an anomalous coronary vessel cannot be selectively identified by CAG. In this report, a 54-year-old man was admitted to the hospital with acute inferior myocardial infarction and had an anomalous origin of the left circumflex coronary artery (LCX) from the first diagonal branch (D1). In CAG, the right CAG showed no significant stenosis and fortunately we found an anomalous origin of the LCX from the D1. The course of LCX was precisely established by 64-slice multi-detector computed tomography.
