The authors analysed statistically 186 cases of the glaucoma patients among 20,785 out-patients who visited to our eye clinic from Jan. 1957 to Dec. 1969. The incidence of the glaucoma was 0.895% which was remarkably lower than the other reports. The following results were obtained. 1) Among the 186 cases, there were 85 male and 101 female patients. 2) There was no significant difference in left and right eye. 3) 51-60 year age group was prevalent (49 cases). 4) The age group over 40 occupied 61.3%. 5) The open angle glaucoma was the highest incidence.

Non-metrical morphologic variations of skull foramina were studied with 250 crania of Korean adults. Studied morphologic variationts were presence of supra-orbital foramen(33.3%), frontal foramen(27.7%), accessory infraorbital foramen(13.2%), accessory lesser palatine foramen(41.0%), Vesalius foramen (16.9%), Huschke foramen(18.8%), condylar canal(62.6%) and parietal foramen(49.8%). The ahsence of posterior ethmoidal foramen(0.2%), zygomaticofacial foramen(7.1%) and mastoid foramen(30.2%) was also observed. The variations were presence of the exsutural location of anterior ethmoidal foramen 30.8%), mastoid foramen(35.9%) and incomplete development of oval foramen(4.9%), foramen spinosum(9.6%), hypoglossal foramen(9.6%). And incidence of these variations were compared with 12 different geographical localitics.

PURPOSE: We investigated whether myocardial SPECT had additional usefulness to clinical, functional or surgical indices for the preoperative evaluation of cardiac risks in noncardiac surgery. MATERIALS AND METHODS: 118 patients (M: F=66:52, 62.7+/-10.5 years) were studied retrospectively. Eighteen underwent vascular surgeries and 100 nonvascular surgeries. Rest T1-201/stress Tc-99m-MIBI SPECT was performed before operation and cardiac events (hard event: cardiac death and myocardial infarction; soft event: ischemic ECG change, congestive heart failure and unstable angina) were surveyed through perioperative periods (14.6+/-5.6 days). Clinical risk indices, functional capacity, surgery procedures and SPECT findings were tested for their predictive values of perioperative cardiac events. RESULTS: Peri-operative cardiac events occurred in 25 patients (3 hard events and 22 soft events). Clinical risk indices, surgical procedure risks and SPECT findings but functional capacity were predictive of cardiac events. Reversible perfusion decrease was a better predictor than persistent decrease. Multivariate analysis sorted` out surgical procedure risk (p=0.0018) and SPECT findings (p=0.0001) as significant risk factors. SPECT could re-stratify perioperative cardiac risks in patients ranked with surgical procedures. CONCLUSION:: We conclude that myocardial SPECT provides additional predictive value to surgical type risks as well as clinical indexes or functional capacity for the prediction of preoperative cardiac events in noncardiac surgery.

PURPOSE: To determine the accuracy of automated computer aided volumetry for simulated small pulmonary nodules at computed tomography using various types of phantoms MATERIALS AND METHODS: Three sets of synthetic nodules (small, calcified and those adjacent to vessels) were studied. The volume of the nodules in each set was already known, and using multi-slice CT, volumetric data for each nodule was acquired from the three-dimensional reconstructed image. The volume was calculated by applying three different threshold values using Rapidia(R) software (3D-Med, Seoul, Korea). RESULTS: Relative errors in the measured volume of synthetic pulmonary nodules were 17.3, 2.9, and 11.5% at -200, -400, and -600 HU, respectively, and there was good correlation between true volume and measured volume at -400 HU (r=0.96, p<0.001). For calcified nodules, relative errors in measured volume were 10.9, 5.3, and 16.5% at -200, -400, and -600 HU, respectively, and there was good correlation between true volume and measured volume at -400 HU (r=1.03, p<0.001). In cases involving synthetic nodules adjacent to vessels, relative errors were 4.6, 16.3, and 31.2 % at -200, -400, and -600 HU, respectively. There was good correlation between true volume and measured volume at -200 HU (r=1.1, p<0.001). CONCLUSION: Using computer-aided volumetry, the measured volumes of synthetic nodules correlated closely with their true volume. Measured volumes were the same at each threshold level, regardless of window setting.

BACKGROUND AND OBJECTIVES: Dual isotope myocardial SPECT, rest thallium-201/dipyridamole stress Tc-99m sestamibi is used to diagnose coronary artery disease. We examined predictive value of myocardial SPECT for the prognosis of patients having or suspected coronary artery disease. MATERIALS AND METHOD: We examined 692 patients referred for dipyridamole stress myocardial perfusion SPECT. Cardiac events (hard and soft events) were followed up with medical record review and telephone interview. Survival analysis and multivariate Cox proportional hazard model were used to find significant predictors and the incremental predictive value of myocardial SPECT. Patients with coronary angiography (n=246) were analyzed in separate group. RESULTS: There were 4 hard events and 3 soft events in 341 normal SPECT group (1.20%/yr). There were 5 hard events and 21 soft events in 351 abnormal SPECT group (4.69%/yr). Survival curve was separated between normal SPECT group and abnormal SPECT group (p<0.01). In univariate analysis, smoking, history of myocardial infarction, typical chest pain and SPECT findings were important variables. In multivariate analysis, SPECT result was the single most independent predictor. Large reversible perfusion abnormality predicted worse prognosis. In patients with coronary angiography, SPECT did not add statistically significant predictive value to the coronary angiography. CONCLUSION: Dipyridamole stress Tl-201/ MIBI dual isotope myocardial perfusion SPECT provided excellent prognostic information. Extent of reversible perfusion decrease was the independent predictor of future cardiac events.

BACKGROUND: The aim of this study was to analyze the questions in the shoulder and elbow section of the Korean Orthopaedic In-Training Examination (KOITE) and compare them with those of the US Orthopaedic In-Training Examination (US OITE). METHODS: Twenty-nine questions in the shoulder and elbow section of the KOITE from 2010 to 2014 were analyzed and compared with those of the US OITE (80 questions) by literature review. A thorough analysis of the contents was performed after categorizing as topics, diagnostic tools, treatment modalities, taxonomic classification, and references. RESULTS: The shoulder and elbow section of the KOITE was 5.8% weight which was similar to the US OITE (5.9%). The most commonly appearing topic was anterior labral injury (17.2%) on the KOITE compared to instability and arthritis (21.3%, each) on the US OITE. Magnetic resonance imaging was most frequently appeared imaging modality on the KOITE (41.0%) compared to the radiograph on the US OITE (43.0%). The Latarjet procedure was the most commonly asked treatment modality (22.2%) on the KOITE, whereas arthroplasty (33.3%) on the US OITE. The KOITE showed an even taxonomic classification distribution compared to the US OITE. Campbell's operative orthopaedics covered 96.6% questions as a reference on the KOITE compared to the Journal of Bone and Joint Surgery, American Volume on the US OITE, which covered 45.0%. CONCLUSIONS: This specific analysis shows us current trends of the shoulder and elbow section of the KOITE and it might be developed for use in the educational curricula for the trainee.
