PURPOSE: The purpose of this study is to find what medical students think the reward for their future work should be and whether they would keep their ideals or abandon them for prestige and wealth by analyzing the book reports of Cronin's The Citadel. METHODS: Participants were 50 medical students of junior class. A month before the classroom lecture, the book and digital video disk were provided. Students had discussions in groups of seven and wrote book reports which include answers of three questions. RESULTS: Regarding what should be the reward for the medical doctor, two-thirds of students (66.7%) answered with spiritual compensation, while one-third (33.3%) chose material reward. In the situation presented to Manson, three-fifths (60.0%) answered they would keep their ideals (idealist), while the remaining two-fifths (40.0%) decided they would abandon them. Less than one-third of students (30.0%) answered they would reveal the corruptions of the doctor's society, while two-thirds (64.0%) would not. CONCLUSION: The larger number of idealists who prefer spiritual reward rather than a material reward represents the innocence of youth as in portrayed in The Citadel.

Although the purpose of orthodontic treatment is to increase the function and esthetics of the jaws along with increasing stability, there are many side effects during the treatment itself, such as root resorption and alveolar bone resorption. Such resorption of the apical root is unpredictable, and may even proceed into the dentin layer. Once the process has begun, it is irreversible. By evaluating the effect of many oral habits, especially that of nail biting, in correlation with the root and the periodontal tissues, the appropriate biomechanics for orthodontic treatment can be taken into consideration, along with the possibility of root resorption and alveolar bone loss during orthodontic treatment, and any legal problems that might occur. Among the male and female patients of the ages 10~15 without skeletal deformity, 63 were chosen as the experiment group with known nail biting habits at time of examination, and within the same age group without nail biting habits as the control. After the orthodontic treatment, number of the experiment group was 31 and the control group was 22. The periapical radiographies of anterior teeth were taken and the assesment of the root length and alveolar bone level were taken before(T1) and after(T2) the orthodontic treatment. The results from this study were as follows : 1. Before the orthodontic treatment, average crown-to-root ratio of the experimental group showed noticeably high values in 4 maxillary incisors and mandibular right central incisor. 2. Before the orthodontic treatment, comparing the root length, maxillary and mandibular right central incisors and both mandibular incisors had a smaller value in the experimental group. 3. Before the orthodontic treatment, comparing and evaluating the alveolar bone loss measured from the cemento-enamel junction to the alveolar bone crest, some crestal bone of the experiment group showed greater loss than the control. 4. After the orthodontic treatment, there was shortening of the root length and loss of the crestal bone in both groups. 5. After the orthodontic treatment, the changes of C/R ratio and the shortening of root length were significantly high in the experimental group. 6. After the orthodontic treatment, the level of alveolar crestal bone showed greater loss in the experimental group.

PURPOSE:Noonan syndrome(NS) is characterized by short stature, congenital heart disease, and typical facies. Recombinant human growth hormone(GH) has been reported to improve growth rate in a similar fashion to that seen in Turner syndrome. We investigated the clinical characteristics and growth reponses to GH therapy in children with NS. METHODS:The cases of sixty seven patients with NS were reviewed retrospectively. Ten of the 65 patients were assessed height, weight and pubertal stage every 3 months during GH therapy. RESULTS:Webbed neck(70%), delayed development(59.7%), low set posterior hairline(56.7%), eye abnormalities(56.7%) and mental retardation(55.2%) were the leading clinical characteristics. Short stature below the 3rd percentile was presented in 73.8 %. Growth patterns in NS children were variable and the evaluation of their growth must be individualized. The increments of height SDS were significant in children with GH therapy(height SDS:from -2.8+/-.6 to -2.3+/-.9, growth velocity:from 4.4+/-.8 cm to 9.2+/-.9 cm during first year, and 6.1+/-.1 cm during second year) (P<0.05). CONCLUSION: This study characterized the clinical profiles in Korean children with NS, which should be further extended with more children with NS. Additionally, the significant increase in final adult height after GH therapy in children with NS should be observed.

All-ceramic restorations have become an attractive alternative to porcelain-fused-to-metal crowns. In-Ceram, and more recently IPS Empress 2 were introduced as a new all-ceramic system for single crowns and 3-unit fixed partial dentures. But their strength and marginal fit are still an important issue. This study evaluated the fracture resistance and marginal fit of three systems of 3 unit all-ceramic bridge fabricated on prepared maxillary anterior resin teeth in vitro. The 3 all-ceramic bridge systems were: (1) a glass-infiltrated, sintered alumina system (In-Ceram) fabricated conventionally, (2) the same system with copy-milled alumina cores (copy-milled In-Ceram), (3) a heat pressed, lithium disilicate reinforced glass-ceramic system (IPS Empress 2). Ten bridges of each system with standardized design of framework were fabricated. All specimens of each system were compressed at 55degree at the palatal surface of pontic until catastrophic fracture occurred. Another seven bridges of each system were fabricated with standard method. All of the bridge-die complexes were embedded in epoxy resin and sectioned buccolingually and mesiodistally. The absolute marginal discrepancy was measured with stereomicroscope at x50 power. The following results were obtained: 1. There was no significant difference in the fracture strength among the 3 systems studied. 2. The Weibull modulus of copy-milled In-Ceram was higher than that of In-Ceram and IPS Empress 2 bridges. 3. Copy-milled In-Ceram (112micrometer) exhibited significantly greater marginal discrepancy than In-Ceram (97micrometer), and IPS Empress 2 (94micrometer at P=0.05. 4. The lingual surfaces of the ceramic crowns showed smaller marginal discrepancies than mesial and distal points. There was no significant difference between teeth (incisor, canine) at P=0.05. 5. All-ceramic bridges of three systems appeared to exhibit sufficient initial strength and acceptable marginal fit values to allow clinical application.

BACKGROUND: Vitiligo is riot quite a rare diseasep; it has about 1% prevalence. The cause of vitiligo is not clear, however, in recent studies an autoimmune origin is freqluei itily mentioned. OBJECT: We tried to an lyze some clinical features of vitiligo and relate them with the presence of autoantibodies. MEHTODS: A total of 381 vitiligo patients was included for the analysis of clinical features. A laboratory study included rhumatoid factor, antinuclear antibocoly, antithyroglobulin antibody and antimicrosome antibody. Some 62 patients were examined for opl thmologic changes. RESULTS: One hundred and one(26.5%) of 381 patients exam ned showed at least one of the autoantibodies tested. Twenty nine pateints showed 2 different aitintibodies. The age at aonset of vitiligo in the autoantibody positive group was 6.6 years later than that of the autoantibody negative group. Autoimmune and/or endocrine diseases were more frequinty found among aut.oantibody positive patients. These diseas s included hyperthyroidism, diabetes me litus and alopecia areata. One patient revealed retinal hypoigmentation and showed no autoantibcidics. CONCLUSION: About 9% of vitiligo patients who were autoantiocyte positive had clinical evidence of diseases associated with the autoantibody. However, it is prudent. to xpect that more patients with t.he autoantibody may develop later systemic autoimmune diseases or endocrinopathies. A long term follow-up of these patients seem:, to be very important.
