PURPOSE: This study was performed to determine the proper reference line for taking axial computed tomograms from which the good cross-sectional views can be reformatted by multiplanar reconstruction. METHODS: Three dry mandibles with implanted gutta percha cones in the extracted socket were scanned axially according to 6 reference lines of 2 mandibular positions with computed tomogram Hitachi W550. The accuracy of measurements of the lengths of implanted gutta percha cones in the each cross-sectional view reformatted from axial computed tomogram by multiplanar reconstruction was evaluated. RESULTS: The difference between the measurements and the real length of implant was smallest in the bucco-lingual views reformatted from the axial views scanned according to the reference line of group V-a. The smaller the angle difference between reference line and occlusal line was, the smaller the difference between the measurements in the bucco-lingual views reformatted from axial views and the real length of implant. The majority of measured widths of implants in the bucco-lingually reformatted views were larger than the actual values. CONCLUSIONS: When the mandible is inclined within the limitation of gantry angle and scanned with the reference line coincident with occlusal plane, the bucco-lingual view can be reformatted without deformation of images from the axially scanned images.

Bodycomposition measurement is useful in the diagnosis of pathology, assessment of disease process and response to treatement in many endoclonologic and metabolic diseases. The Techniques used currently are mostly indirect, often expensive, difficult and time-consuming. A new method for estimation of body composition, infrared interactance, is rapid, safe, noninvasive, and may be useful in research and clinical studies. Body composition was assessed in 51 children and adolescants with insulin-dependent diabetes mellitus by infrared interactance method using a Futrex 5000A body fat content analyzer. Percentage body fat of pubertal girls was 26.1+/-7.6%, significantly greater than prepubertal girls (17.9%, 0<0.01) and pubertal boys (19.9%, p<0.05). Body fat content was increased through puberty in girls. but not increased in boys. Our data do not explain why body fat of pubertal boys was not increased. There was no significant association of insulin dose and HbA1C level with percentage body fat. Thus, we had to attempt measure calorie intake, activity level and diet composition. Our data revealed that dietary carbohydrates may prompt fat deposition, but energy balance does not explain the differences between pubertal girls and boys. In conclusion, Body fat increased through puberty in girls, but the etiology of differences in pubertal girls and boys is not clear, and in view of potential adverse effect of fat depostion of long-term health, further larger case-contolled study will be necessary.

The traditional treatment of piriformis syndrome includes heat modality, deep muscle massage, slow stretch exercise, injection of local anesthetics, and surgical division of piriformis muscles in some selected cases. More recently, the use of botulinum toxin (BTX) for the treatment of piriformis syndrome has been suggested. We experienced two cases of piriformis syndrome with distinctive clinical feature. The symptoms of these two cases were not controlled by conservative managements including physical therapy, direct injection of lidocaine or steroid, or caudal block. So we injected Type A BTX in the piriformis muscle with the guidance of CT scan. 8 weeks after the botulinum injection, symptoms had almost completely disappeared, and follow up CT scan showed sufficient atrophy of piriformis muscles. The CT guided BTX injection in the piriformis muscle might emerge as a feasible technique to obtain a good local therapeutic effect without risk of imprecise inoculation.

PURPOSE: To evaluate the use of the vertical tube shift from a panoramic film and a periapical film to localize unerupted maxillary incisors and supernumeraries. MATERIALS AND METHODS: The total of 103 displaced maxillary incisors or embedded supernumeraries were examined in this study. The vertical tube shift technique with panoramic and periapical radiography by normal projection taken and compared to localize the position of the embedded maxillary incisors or supernumeraries by a radiologist and 5 general dentists. The gold standard used for the radiographic comparisons was the true position of the embedded tooth as confirmed by horizontal tube shift technique using three periapical radiographs. The general dentist examiners were instructed on the use of the modified acronym "SLDOBU" by the radiologist as it pertains to panoramic radiographs as the principle of vertical tube shift. RESULTS: All of the embedded maxillary incisors and supernumeraries were successfully located using the vertical tube shift from a panoramic and a maxillary anterior periapical radiograph by the radiologist and 5 general dentists. CONCLUSION: The use of a panoramic film with a periapical film combination for a vertical tube shift can be useful to localize unerupted maxillary incisors and supernumeraries.

Cleidocranial dysplasia is a rare and autosomal dominent disorder characterized by aplasia or hypoplasia of the clavicles, an open fontanelle, dental abnormalities, and short stature. A 17-year-old female who presented with short stature and subsequent delay in eruption of permanent teeth is described. she showed the abnormal hypermobility of the shoulder, ocular hypertelorism and concave nasal bridge. Radiographs revealed the underdeveloped maxilla, defect of the cranium in the fontanelle region, and aplasia of the clavicles. Characteristically, panoramic view revealed near parallel-sided borders of the ascending ramus and downward curvature of the zygomatic arch with hypoplasia. The prolonged retention of deciduous teeth with delayed eruption of permanent teeth and multiple embedded supernumerary teeth were striking. Radiographic and clinical investigations revealed Cleidocranial dysplasia.

OBJECTIVE: To investigate the safety of early symptom limited exercise stress test (GXT) performed within 10 days after coronary intervention in acute coronary syndrome patients. METHOD: Forty-six patients with acute coronary syndrome including unstable angina (UA) and acute myocardial infarction (AMI) were recruited. All of them performed GXT within 10 days after coronary intervention and received cardiac rehabilitation for 6 weeks. RESULTS: Mean age of the patients was 57.6+/-9.8 years (unstable angina 26 patients, acute myocardial infarction 23 patients). The number of the patients complained of cardiac events during GXT was 8 (16%); chest pain (3), ischemic changes on electrocardiogram (2) and hemodynamic instability (3). However, none of them showed any major adverse cardiac events such as acute myocardial infarction (AMI). Major cause of termination of GXT was patient's request such as dyspnea, fatigue, and musculoskeletal pain. After early GXT, there was no significant difference between two groups in all variables (p>0.05). CONCLUSION: Early GXT was safe in acute coronary syndrome patients and did not show any significant difference between UA patients and AMI patients.
