Seven finite element models were constructed in mandible having single screw-type implant fixture connected to the second premolar-shaped superstructure, in order to evaluate how the length, diameter and platform shape of a screw-type fixture influence the stress in the supporting tissue around fixtures. The superstructure were made using UCLA abutment, and connected to the fixture with abutment screw. Each finite element model was varied in terms of length, diameter, and platform shape of the fixture according to the commercial fixture(3i Implant Innovations Inc, Palm Beach Gardens, FL33410, USA) while the superstructure and the mandible with a single fixture placed in it shared no difference in terms of appearance. In each model, 250N of vertical load was placed on the central pit of an occlusal plane and 250N of oblique load placed on the buccal cusp. The stress distribution in the supporting tissue and the other components was analysed using 2-dimensional Finite element analysis and the maximum stress in each reference area was compared. 1. Under lateral loading, the stress was larger in the larger in the abutment/fixture interface, and in the crestal bone, compared to the stress pattern under vertical loading. 2. The amount of stress at the superstructure was similar regardless of the length, diameter and platform shape of a fixture. 3. Around the longer fixture, the stress was decreased at the bone crest and subjacent cancellous bone and increased in the cancellous bone area apical to the fixture. 4. Around the wider fixture, the stress was decreased at the abutment/fixture interface, and the bone crest and increased in the cancellous bone area apical to the fixture. 5. Around the fixture having wider platform, less stress was resulted at the abutnent/fixture interface and the upper part of the cortical bone, compared to the fixture having standard platform. In short, the stress distribution of the supporting tissue was affected by length, diameter, and platform shape of a fixture, and the fixture which was larger in diameter and length could reduce the stress in the supporting tissues at the bone-fixture interface and bone crest area.

Bechet's disease(BD) is a chronic inflammatoroy condition involving several organs inclu-ding gastrointestinal tract. Gastrointestinal tracts involvement in BD has been identified throughout the entire alimentary tract and commonly accompanies ulcerative lesions in the small and large bowel. It is debatable whether BD could be included among seronegative spondyloarthropathy (SPA).SPA usually occurs without overt sign of intestinal inflammation, but significant number of patients have asymptomatic intestinal inflammation, usually affecting ileum. Since most patients with SPA in-cluding BD are treated with NSAIDS. However, NSAID may play a role in aggravation or provo-cation of intestinal inflammation. Special attention to asymptomatic intestinal inflammation is needed, especially when NSAIDs are used for management of arthritic symptom in SpA. We experienced a case of BD which was complicated by a massive small bowel bleeding precipitated by NSAID use. 저자들은 베체트병 환자에서 비스테로이드성 소염진통제 사용 후 발생한 대량 소장 출혈의 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Purpose : The purpose of this study was to investigate drinking motives and the drinking-related problems of Korean high school students at a city in Jeonbuk province. Methods : There were 657 students from two academic and two vocational high schools at J city in Jeonbuk province. The sample was collected using a stratified sampling method and the data was collected from June 30th to July 16th 2003. The study instrument used to examine drinking motive was a 20.item summated scale (Cronbach's α = .95) and for drinking-related problems was an 18 item summated scale (Cronbach's α = .91). The data was analyzed using SPSS/PC+ by percentage, χ2.test, t-test and correlations. Results : 1. Drinking experience: Among the high school students, 74.3% of them had drinking episodes. Female students started drinking later (χ2 = 12.857, p = .002) and had more drinking friends (χ2 = 7.785, p = .020) than males. Vocational school students drank more frequently (χ2 = 32.138, p = .001), had more heavy drinking episodes (χ2 = 40.370, p = .001). 2. Drinking motives & Drinking-related problems: The mean score of drinking motives was 31.2 ± 11.12 out of 80 and that of drinking-related problems was 21.8 ± 5.85 out of 72 points. Neither score were stronger was significantly different according to gender and grade. On the other hand, both drinking motives (t = .4.077, p = .001) and drinking-related problems (t = .3.423, p = .001) were stronger in vocational school students than in academic school students. The correlation between drinking-related characteristics and problems were weak (from r = .286 to r = .520) but the correlation within the subcategories of drinking motives was high such as between enhancement and coping (r = .822) and enhancement and social motives (r = .822). Conclusion : The majority of Korean high school students start to drink during their junior high school days. Drinking motives and drinking-related problems were not serious but the drinking motives and the drinking-related problems are stronger among vocational school students. As a result, school-based health education and counseling programs should focus on solving drinking motives than on drinking-related problems.

Ticlopidine is a antiplatelet agent used to prevent acute thromboembolic artery occlusion. It is a thienopyridine derivative that inhibits platelet aggregation through an adenosine 5'-diphosphate(ADP) -dependant pathway. Ticlopidine has been associated with serious hematologic effects. Neutropenia has been seen with ticlopidine with an incidence of 2.1% and 0.8% incidence of severe neutropenia. We reported here, one case of severe neutropenia developed after use of ticlopidino. Patient suffered from an acute cerebral infarction. Hr developed neutropenia 1 year after treatment with 100 mg ~ 500 mg/daily. After stopping riclopidine, he was recieved Granulocyte Colony Stimulating Factor (G-CSF). In two days after G-CSF administration, neutropenia was quickly improved.

The most serious acute complication of DM is diabetic ketoacidosis (DKA). Medical and surgical illnesses account for 50% of episodes of DKA. Infection, myocardial infarction, cerebral vascular accidents, gastrointestinal bleeding, trauma, pancreatitis, and burns are the most common medical causes. The mortality rate from DKA has been reduced to less than 5%. Patients with insulin-dependent diabetes mellitus (IDDM) are more prone to DKA than those with noninsulin-dependent diabetes mellitus (NIDDM). Older diabetics account for approximately 75% of patients who present with DKA. The signs and symptoms of DKA result from hyperglycemia or ketoacidosis. We report a case of anesthetic management of a patient with noninsuline-dependent diabetic ketoacidosis after trauma.

Objectives: As automobile part manufacturing is characterized by high speed and high repetition, observation methods which are usually utilized for static posture are inappropriate to evaluate musculoskeleatal risk factors. This study quantified the risk factors of musculoskeletal disorders on the forearm and suggested exposure limits by estimating the risk factors using surface electromyography (EMG) and electrogoniometer. Methods: Ten percent of the total workers at 3 automobile part manufacturing factories were randomly selected, and 99 male workers were recruited as study subjects. The study was conducted during May 2003 to September 2004. The workers were equipped with electrogoniometers on the wrist and the elbow, surface EMGs on the skin of the flexor digitorum superficialis (FDS) and extensor carpi radialis (ECR) muscles, and the heart beat recorder during work as indicators of joint movement, local muscle tension and physical work load, respectively. Results: After controlling for age, body mass index and job stress, wrist flexion maximum angle, FDS relative activity (RA) and ECR RA were significantly associated with forearm musculoskeletal symptoms. The odds ratios of the forearm were 5.0(95% CI: 1.1-22.7), 14.0(95% CI: 1.5-128.8) and 7.3(95% CI: 1.1-49.4) for wrist flexion maximum angle more than 76˚, FDS RA more than 2.8%, and ECR RA more than 3.5%, respectively. Conclusions: Joint angle and focal muscle activity were associated with forearm musculoskeletal symptoms. To reduce forearm musculoskeletal symptoms among automobile part manufacturers, the wrist flexion angle, and FDS and ECR activity need to be reduced below the guidelines recommended in this study.

Nuss operation is one of the surgical procedure for pectus excavatum and it's method is the insertion of convex steel bar under the sternum through small bilateral thoracic incision. As the patients is growing, the thorax can be compressed gradually by steel bar. So Nuss bar needs to be removed two years after Nuss operation. This study was undertaken to assess the effect on the repiratory mechanics before and after the removal of the Nuss bar. Twenty patients with previous Nuss operation were allocated for the removal of Nuss bar. Lung mechanics (dynamic lung compliance, static lung compliance, and airway resistance), hemodynamic change (heart rate, systolic pressure, and diastolic pressure), and pulmonary gas exchange (arterial oxygen tension, arterial carbon dioxide tension, pulse oximeter saturation, and end tidal carbon dioxide tension) were measured before and after removal of Nuss bar. Respiratory mechanics (dynamic and static lung compliance, inspiratory airway resistance), pulmonary gas exchange and hemodynamic parameter were unchanged before and after the removal of Nuss bar. We concluded that lung mechanics were not changed before and after the removal of Nuss bar in the patients with pectus excavatum and the 95% patients were satisfied with operation.

To study the prevalence of common dermatoses 37,638 and 30,286 new outpatients who visited dermatology clinic with Hanyang University Hospital from January 1981 to December 1985 and from January 1986 to December 1990, respectively. Among the 37,638 outpatients in the first 5 years, the total number of male patients were 18,107(48.1%) and female patients were 19,531 (51.9%). Among the 30286 outpatients in the last 5 years, the total number of male patients were 14,705 (48.6%) and female patients were 15,581 (51.4%). In the both periods, the most frequent age groups was 21-30 (27.3%,25.2% respectively). The 15 common dermatoses, bacterial infection, seborreic dermatitis, drug eruption, verruca, syphilis, psoriasis, herpes zoster, and hypopigmentary disorder, in order of frequency. In thelast 5years, dermatophytosis, contact dermatitis, urticaria, acne, other eczema, atopic dermatitis, seborrheic dermatitis, bacterial infection, drug eruption, verruca, gerpes zoster, psoriasis, hypopigmentary disorder, scabies and syphilis were the 15 common dermatoses, as frequency. In both periods, the dermatosis which showed annually increasing tendency was dermatophytosis and those of decreasing tendency was bacterial infection. In the both periods, dermatophytosis, urticaria, bacterial infection, seborrheic dermatitis, verruca, and hypopigmentary disorder occurred most frequently during the summer season, and the incidence of other ecxema, scabies, atopic dermatitis, and herpes zoster increased during the winter season.

Kyphoscoliosis is a disease manifested as lateral curvature of spine and accompanying rotation of the vertebrae, resulting in distortion of rib cage. Restrictive lung disease and pulmonary hypertension progressing to cor pulmonale are the major cause of mortality in patients with kyphoscoliosis. We had experienced a successful spinal and caudal epidural anesthesia for the open reduction and internal fixation with plate of fractured femur shaft in two patients with severe kyphosoliosis. We had chosen regional anesthesia as an anesthetic method because of there poor pulmonary function and severe deformities of thoracolumbar spine. We could achieve the adequate anesthetic sensory dermatome level, T_(5) and T_(8), for operation without any significant deterioration of blood pressure and respiration. We recommended that regional anesthesia is a useful anesthetic method for a patients with severe kyphoscoliosis when the operation on hip or lower extremity is required.
