The purpose of this study is to investigate the cephalometric characteristics of the open-bite patients with DJD of TMJ. The DJD open-bite cases were compared with normal samples and Class II open-bite cases with normal TMJ respectively. Twenty three open-bite patients with bilateral DJD of TMJ(13.9~35.3 years old, Group I) were selected from the Department of Orthodontics, SNUDH. Group II consisted of thirteen Class II open-bite cases(13.2-27.4 years old) with no TMD signs/symtoms and good condylar shapes. Group III samples were the forty eight healthy dental students who have Class I molar relationships with no history of orthodontic treatment, good facial balance and no TMD symptoms(20.0-26.8 years old). First, sixty measurements in the lateral cephalometric radiographs and analysis of variance(p<0.05, Scheffe) were used to compare these three groups. The seven measurements showed significant difference(P<0.05) between Group I and Group II. After analysis of variance, six of them were used for the discriminant analysis(Wilks', stepwise analysis) and the discrminant function for Group I/Group II was obtained. The results and conclusions were as follows: In most of the measurements, Group I and Group II showed the same skeletal and dental characteristics. But seven of the sixty measurements(FH-PP angle, SNB, FH-ArGo angle, articulare angle, gonial angle, upper gonial angle and Ar-Go length) were significantly different(p<0.05) between Group I and Group II. These differences may be explained by the fact that in DJD cases the mandible rotated backward due to the shortening of the ramus following the degenerative destruction of condylar head and its surrounding structures. The resulting discriminant function was: D = -0.l20X1 + 0.066X2 + 0.144X3 - 0.058X4 + 2,000, where X1=ArGo length(mm), X2=SArGo angle(degree), X3=FH-PP angle(degree), X4=Gonial angle(degree), Mean of the group centroids was -0.555 and percent of the "grouped" cases correctly classified was 88.89%.

Dermatitis Herpetiformis rarely in childhood, and certain features of the disease in children differ from its manifestations in adults. Juvenile dermatitis herpetiformis appears not to be the same disease as the typical dermatitis herpetiformis of adults. Juvenile dermatitis herpetiformis has been described as a predomimantly bullous disease, but rarely papulovesicular eruptions. This bullous eruption in children must be considered in the several entities such as bullous pemphigoid and erythema multiforme. Juvenile bullous dermatitis herpetiformis has not responded routinely to sulfapyridine and sulfone therapy. A 15-month-old child whose skin lesions fulfilled clinical, histologic, and therapeutic criteria for Juvenile dermatitis hepetiformis is reported. The skin lesions showed bullous eruptions and also complained of severe itching sensation different from bullous Juvenile dermatitis herpetiformis.

On the basis of stastistical awlysis trend of increase in syphilis patients in Korea closely resembles that reported in other countries. Among these patients, it should be noticed that thy were highly infectious, showing early latent syphilis. Nevertheless, the available diagnstic test for syphilis has only been limited to the Non-treponemal antigen test. Moreover not only schedules employing in the treatment f disease have been different among physicians but the follow up test for each patient bas been quite impossible. In these respects, the author strongly suggests that the effective measures for the prevention and treatment of syphilis will be required as a national policy.

Partial Unilateral Lentiginosis (PUL) is a rare pigmentary disorder characterized by the numerous lentigines confined to a body segment, with a sharp demarcation at the midline. We report two cases of PUL. A 38-year-old woman had asymptomatic discrete small hyperpigmented macules that were scattered on the T7~L1 dermatomes on the left side of her trunk and were clearly demarcated in the midline on both anterior and posterior sides. In the other case, an 18- year-old woman had hyperpigmented macules that were scattered on the left neck, shoulder, and anterior chest. Other anomalies including neurofibromatosis, neurologic anomalies, and multiple lentiginous syndrome were not related in both cases. We report two cases of PUL having no other anomalies.

In 1933 Shope described an infectious papilloma of wild cattontail rabbits. Shope rabbit papilloma is a virus-induced epidermal neopIasm indigenous to western cottontail rabbits and readily transmissible to domestic rabbits by inocuiation with an cell-free extract of wild cottontail papilloma. Shope papilloma induced in the domestic rabbits may spoataneously, remain benign, or progress to carcinoma. Kidd et al. (1936) noted that the regression is not correlated with the titer of virus neutralizing antibody. The possibility that papilloma regression is brought about by a mechanism anaIogous to that operating in allograft rejection was suggested by kidd et al. (1938) with the view of the histological resemblance between papilloma regression and rejection of allografted tissue. That regression is mediated by an immune mechanism is strongly indicated by the findings of Evans et al.(1962) that the proportion of rabbits showing regression is substantially increased by vaccination of rabbits with their own papilloma tissue or with papilloma tissue from another rabbits. McMichael (1967) demonstrated that suppression of regression was achieved by use of large doses of corticosteroid. The effect of 5-fluorouracil on human warts was mentioned as being effective by Goldman et al. (1963). In Korea resinous extract from Paulownia coreana has long been used empirically in the treatment of human warts. In this investigation effects of dexamethasone administration on the development and the spontaneous regression of Shope papillomas in domestic rabbits were studied. At the same time, observations were made to evaluate the comparative effectiveness of topical application of 5% 5-fluorouracil ointment and resinous extract from Paulownia coreana on Shope papilloma in the domestic rabbit. The results are summarized as follows: l. Administration of dexamethasone significantly reduced the spontaneous regression of Shope papillomas in domestic rabbits by 12 weeks after virus inoculation. 2. Topical application of 5% 5-fluorouracil ointment on Shope papillomas cured the tumors by 4 weeks of drug application. However, similar treament with resinous extract from Paulownia coreana was without any demonstrable effects. 3. Marked losses of body weights became manifest in dexamethasone treated rabbits. 4. Reinoculation of Shope papilloma virus into 2 rabbits whose papillomas had regressed 3 months ago failed to produce papillomas.

Tuberculosis of the bone and joints is one of the genralized manifestation or solitary localized lesion. Although the incidence of the tuberculous osteomyelitis of long bone is decreasing with good neutrition, development of preventive medicine and improvment of treatment regimen, it is still one of the common diseases in Korea and must be considered in the differentil diagnosis of common orthopaedic complaints. Thirty five cases of tuberculous osteomyelitis of long bone were studied in our department from Junuary 1973 to December 1984. The results are as follows: 1. Long bone tuberculous osteomyelitis were 35 cases (6.6%) from the overall tuberculous lesion of the bone and joints. (534 cases) 2. Childrean and young adults were common age group. 3. Concomitant pulmonary tuberculosis was found in 11 cases. 4. Radiologic findings showed variable lesions including osteolytic, cystic, sclerotic and destructive forms. 5. Confirmative diagnosis could be made by smear, culture of the lesion and pathologic findings. 6. The overall results treated with curettage and bone graft as well as proper antituberculous medication were satisfactory.

OBJECTIVE: The purpose of this study was to investigate the changes in dentofacial morphology of non-orthodontically treated female patients with TMJ disk displacement. METHODS: The sample consisted of 25 Korean female patients with bilateral TMJ disk displacement who visited the Department of Orthodontics, Seoul National University Dental Hospital from 1996 to 2006. Disk displacements were diagnosed using the magnetic resonance imaging (MRI) of both TMJs. Baseline (T1) and follow-up (T2) lateral cephalograms were analyzed. The mean age of samples at T1 was 18.1 +/- 3.5 years (range 14.2 - 25.8 years) and at T2, 21.1 +/- 3.5 years (range 16.2 - 28.0 years). The mean observation period was 3.0 +/- 1.9 years. Descriptive statistics for each variable were calculated at baseline (T1) and follow-up (T2) stages, and during the observation period (T2-T1). RESULTS: Skeletal changes were found in 64% of the non-orthodontically treated female patients with TMJ disk displacement during the observation period. The L1 to Mandibular plane distance (mm) increased significantly by 0.8 mm (p < 0.01). But there were no significant differences in the other dental relationship variables (overjet, overbite, U1 to palatal plane) during the observation period. Most patients with skeletal changes showed a backward rotation of the mandible. The ratio of the rotation was a decrease of SNB by 0.43degrees for every 1degrees increase of FMA (Spearman rho = -0.660, p < 0.01). A few patients showed a distal shift of the mandible without rotation or significant changes in the vertical dimension. CONCLUSIONS: During observation periods without orthodontic treatment, non-growing patients with TMJ disk displacement showed dentoskeletal changes, mainly backward rotation of the mandible.
