Making a precise and ideal set-up model is an essential part in the indirect bonding procedure for lingual orthodontic treatment. To evaluate the accuracy of the making a set-up model, 22 adult patients who received lingual orthodontic treatment with 4 bicuspid extractions were selected, and 3 sets of dental models (before, set-up, and after treatment) were measured using the set-up model gauge, an instrument for measuring the inclination and angulation of the clinical crowns on the dental model. Two sets of lateral cephalograms (before and after) from each patient were also evaluated. The mean difference between the before treatment model and the set-up model was -3.93 +/- 6.98 degrees for the inclination and 1.87 +/- 5.79 degrees for the angulation. And the mean difference between the set-up model and the after treatment model was -4.31 +/- 5.91 degrees labiolingually and -2.16 +/- 3.27 degrees mesiodistally. The after treatment model differed from the before treatment model about -8.24 +/- 5.39 degrees in inclination. There were no significant difference between the measured gauge that measured from the dental model using the set-up model gauge and the calculated gauge angle measured from the lateral cephalogram using constructed points and lines. Using the set-up model gauge, it is possible to evaluate the study model 3-dimensionally in relation with the patient's lateral cephalogram and establish whether the doctor's prescription or overcorrection is built in the set-up model precisely.

OBJECTIVES: The purpose of this study is to investigate the characteristics of drinking patterns and the prevalence of hazardous drinking and alcohol use disorder with the assessment of alcohol policy needs in community population of urban city in Korea. METHODS: Data was collected from 1,000 residents in a single urban city in Korea, from June 1 to July 31, 2011 by a questionnaire. As research tools, socio-demographic characteristics composed of variables based on study purpose, alcohol problems and alcohol use disorder state scales composed with Alcohol Use Disorder Identification Test(AUDIT) and Cut down, Annoyed, Guilty, Eye-opener(CAGE), and the assessment of alcohol policy needs in community population questions were used. RESULTS: The lifetime experience of alcohol drinking was 97.4%. For the frequency of drinking, 21.9% of population responded 2 to 4 times per weekly. 24.4% of male had one time or more high risk drinking, defined as having four or more drinks in a sitting, per week. 51.6% experienced the first time drinking of alcohol in adolescence. The lifetime prevalence of hazardous drinking and alcohol use disorder were 14.9% and 3.3%, respectively using AUDIT. Alcohol use disorder were 9.6% with the CAGE scale. Problem drinking were 8.4% in this study. They requested the program such as prevention education(57.2%), construction of liaison system to treatment facilities( 50.1%), alcohol counseling and intervention(41.7%), and rehabilitation program(39.8%). CONCLUSIONS: These results demonstrate that alcohol problem and alcohol use disorder were much prevalent, and these problem started in the earlier age. It is necessary to develop an effective alcohol prevention program or policy with considering the needs in community population.

PURPOSE: To compare ocular biometry and refractive results measured using conventional applanation ultrasonography and 3 different optical interferometries, Lenstar LS900(R), AL-Scan(R) and OA-2000(R). METHODS: The biometries of 31 cataractous eyes were measured using ultrasonography, Lenstar LS900(R), AL-Scan(R) or OA-2000(R). The axial length, anterior chamber depth and keratometry were measured. The SRK/T formula was used to calculate intraocular lens power. Two months after cataract surgery, the refractive outcome was determined and results from the 4 different biometry methods were compared. RESULTS: Axial lengths were 23.39 +/- 0.95 mm, 23.42 +/- 0.98 mm, 23.43 +/- 0.98 mm and 23.44 +/- 0.98 mm measured using ultrasonography, Lenstar LS900(R), AL-Scan(R) and OA-2000(R), respectively with no statistically significant differences observed (p = 0.996). The anterior chamber depth and keratometry were 3.14 +/- 0.41 mm, 3.10 +/- 0.38 mm and 3.13 +/- 0.39 mm (p = 0.936) and 44.41 +/- 1.52 D, 44.54 +/- 1.57 D and 44.44 +/- 1.52 D (p = 0.937) for Lenstar LS900(R), AL-Scan(R) and OA-2000(R) respectively. There were no statistically significant differences between the 3 optical devices. The mean absolute error of the 4 different devices were not statistically significant (p = 0.722). CONCLUSIONS: The ocular biometric measurements and prediction of postoperative refraction using ultrasonography, Lenstar LS900(R), AL-Scan(R) or OA-2000(R) showed no significant differences.

Conventional cephalometrics have inherent errors because their evaluation is performed in two-dimension for threedimensional object. To compensate these errors, three-dimensional cephalograms - derivation of three-dimensional data from conventional lateral and postero-anterior cephalograms - were developed. In this study, the accuracy and precision of three dimensional cephalograms were determined by means of 10 linear and 12 angular measurements on 36 acrylic skull models and by the comparison of conventional lateral cephalograms. The results were as follows 1. Mean difference between three-dimensional cephalograms and actual models in linear measurements was 0.94+/-0.62 mm and mean rate of magnification of three-dimensional cephalograms was 100.31+/-0.91%. There were no statistically significant differences between three-dimensional cephalograms and actual models in linear measurements(alpha=0.1). 2. Mean difference between conventional lateral cephalograms and actual models in linear measurements was 6.44+/-1.48 mm and mean rate of magnification of lateral cephalograms was 106.99+/-1.45%. There were statistically significant differences between lateral cephalograms and actual models in linear measurements(P<0.005). 3. Mean difference between three-dimensional cephalograms and actual models in angular measurements was 1.22+/-0.82degrees and mean rate of magnification of three-dimensional cephalograms was 105.71+/-12.07%. There were no statistically significant differences between three-dimensional cephalograms and actual models in angular measurements(alpha=0.1). 4. Mean difference between conventional lateral cephalograms and actual models in angular measurements was 1.70+/-0.94degrees and mean rate of magnification of lateral cephalograms was 106.35+/-15.70%. There were no statistically significant differences between lateral cephalograms and actual models in angular measurements(alpha=0.1). There were similarity between three-dimensional and lateral cephalograms in angular measurements.

Routine chest radiography in a 21-year-old man revealed the presence of an asymptomatic mass at the right lower lung field. Chest radiographs showed multiple cysts with air-fluid level and air-meniscus within the consolidation at the right lower lung field. Chest CT scans demonstrated a non-enhancing solid mass, with air-meniscus, within a thin walled cavity, and multiple cysts with fluid or air-fluid level at the posterior portion of the right lower lobe. An abnormal artery was seen at the level of the 12th thoracic vertebra. Thoracic aortography revealed a feeding artery arising from the descending thoracic aorta and supplying the parenchymal lesion. We report the typical radiologic findings of intralobar pulmonary sequestration with aspergilloma, a condition confirmed by surgery and the pathologic findings.
