The purpose of this study was to examine the familial tendency of the patients with mandibular prognathism in three generations and to define the relationship between the familial tendency and the skeletal class III morphology. The probands of this study were 103 orthognathic surgery patients with skeletal Class III malocclusions who had undergone (48 men, 55 women) mandibular set-back surgery. A questionnaire was given to patients who sought surgical treatment for excessive mandibular length, and all answers were confirmed in interviews. Lateral cephalograms were analyzed in cranial base parameters, mandibular positional parameters and mandibular skeletal parameters. In the examined families, 58.3% had at least one member other than the proband who had mandibular prognathism. The affected ratio of total relatives was 4.5%, and the value was higher in first-degree (13.4%) than second-degree (5.9%) and third-degree relatives (1.7%). The affected ratio was 51.9% in the offsprings who had at least one affected father or mother. The comparison of the groups according to the familial tendency showed no significant craniofacial skeletal measurments. In conclusion, skeletal class III malocclusion showed high familial tendency, suggesting a significant genetic influence in the etiology. However, the patient's familial tendency did not show the special craniofacial patterns compare to the subjects without familial tendency.

The authors observed 2 cases of fibrous dysplasia on the cranial and maxillofacial bones in 31, 28 aged sisters, who had come to the Infirmary of Dental College, Yonsei University. The serial roentgenograms and clinical findings had been taken and the results established as polyostotic fibrous dysplasia according to the findings in their images. The authors have obtained the results as follows: 1. Bony expansion of the mandible occured at 18 years of age and the facial assymetry appeared due to development of the lesions. 2. The traumatic history were not noted but weak tendency of familial history noted 3. Endocrine disturbances, hyperpigmentation on the skin and premature puberty in the infancy were not noted. 4. We have concluded these diseases as polyostotic fibrous dysplasia on the cranial and maxillofacial bones with weak familial tendency according to the findings

Tetralogy of Fallot has shown its familial aggregation in several familial studies. This reported case is another example which occurred in a family in two brothers. They revealed no cytogenetic abnormalities, but the anatomical cardiac malformation of them showed much similarity, total conal defect in ventricular septum and .one had patent foramen ovale, the other atrial septal defect. The familial recurrence tendency of Tetralogy of Fallot as well as other congenital heart diseases could be explained on multifactorial inheritance as shown in many reports. In spite that we couldn`t find out any environmental trigger or teratogens, our case may be accepted on the base of multifactorial mechanism.

치은 섬유종증은 유리 치은과 부착 치은이 점진적으로 증식되는 비염증성 질환이다. 대부분 가족력이 있으며 영구치 맹출과 함께 발병하지만 유치 맹출시기에 드물게 출생 시부터 나타나기도 한다. 본 6세 여아의 경우 태어날 때부터 치은의 일부가 증식되어 있었고 가족력 및 치은 증식을 유발하는 약물을 복용한 병력은 없었다. 구강내 검진 시 섬유성 치은 증식 이 관찰되어 절제 생검을 시행하였고 그 결과 치은 섬유종증으로 진단하였다. 치은 섬유종증의 치료는 치은 절제술과 철저한 구강 위생의 관리이다. 그러나 치료 후 재발성 때문에 치료시기에 대해서는 논란 중이다. 일반적으로 영구치가 모두 맹출 한 이후에 치료할 것을 추천하지만 조기 치료는 구강의 기능 및 환아의 심미적, 심리적인 문제점을 개선시켜 주는 장점이 있다.

To assess the proportion of spectacles-wearing and an aspect of familial aggregation of myoptic spectacles-wearing and to observe the birth cohort for myoptic spectacles-wearing, a nationwide self-administered questionnaire survey was conducted from March 11 to September 19, 1985 A probability sample of 13,346 persons was taken from 180 enumerated districts designated by the fifth nationwide tuberculosis prevalence survey from Korean Institute of Tuberculosis. The major findings of this survey are as follows: 1) Total of 62.5% of the study population lived in urban area whereas 37.5% lived in Eup-Myun area. There was statistically significant difference in age and sex distribution between two residential area. 2) The percentage of spectacles-wearing was 8.3% and among these, myoptic and hyperoptic spectacles were 6.0%, 2.3%, respectively. A total of 8.5% of the male study population wore spectacles and this was slightly higher than the female (8.0%). 3) Among the occupational groups, students were the highest myoptic spectacles-wearing group whereas professionals were the highest hyperoptic spectacles-wearing group. 4) The proportion of myoptic spectacles-wearing was higher in female students than in male students respectively 11.6%, 8.7%. There was an increasing tendency of spectacles-wearing as age increased. 5) The age-sex adjusted prevalence rate of myoptic spectacles-wearing by residential areas was 2 times higher in urban area than Eup-Myun area 6) A wearing of the myoptic spectacles in early age was observed in recent birth cohort than remote birth cohort. 7) There was a tendency of familial aggregation for myoptic spectacles-wearing. The proportion of myoptic spectacles-wearing was 6 times higher for those who had parents wearing spectacles. 8) 60.9% of the total myoptic spectacles-wearing persons received the eye-specialist's order and 44. 9% for the hyperoptic spectacles wearing.

우리나라 농촌지역의 회충감염에 있어서 연령에 따른 재감염률의 차이 및 재감염의 가족집적성에 주안점을 두고 재감염의 특성을 파악하고자 하였다. 1977년부터 1980년까지 경기도 화성군의 11개 마을 전주민에 대하여 2, 4, 6 및 12개월 간격으로 pyrantel pamoate를 사용하여 반복집소투약하면서 각 투약간격동안 발생한 누적재감염율을 충란양성여재 및 투약후 2일간 전대편내에서의 충체양성여부를 종합하여 구하고 비교분석하였다. 결과를 요약하면 다음과 같다. 1. 연령별 재감염률은 모든 투약간격 군에서 소아가 성인에 비해서 월등히 높은 것으로 나타났다. 가장 높은 재감염률 및 재감염량은 학령전 아동군에서 관찰되었고 그 다음은 국민학생 연령군이었다. 또, 이러한 연령별 재감염률의 차이는 여자보다 남자에서 훨씬 뚜렷하였다. 2. 재감염자는 어느 특정가족에 집중적으로 발생하는 강한 가족집적성이 관찰되었고 이 결과는 회충의 재감염이 무작위로 일어나는 것이 아니고 동일한 환경을 가진 특정가족간에 빈발하고 있음을 의미하고 있었다. 이상의 재감염 특성을 감안할 때 우리나라 농촌의 회충 재감염은 이른바 정국감염(dooryard infection)에 의한 것으로 추측되었으며, 또 보다 효과적인 집회관리를 위해서는 학령전 아동이 반드시 관리대상에 포함되어야 할 것으로 생각되었다.

Neurofibromatosis is an autosomal deminant neurocutaneous systemic disease characterized by multiple Cafe-au-lait spots. generalized cutaneous neurofibromatosis. central nervous system tumors. skeletal defects and a myriad of somatic and endocrinologic abnormalities. It occurs in about 1:3000 live births and both sexes are equally affected. From 1989 to 1992, 21 patients who admitted to our department were evaluated in clinical aspects. Then we conclude as follows: 1) The onset was usually before 10 years of age. and the incidence between the sexes was approximately the same. 2) The familial tendency was approximately 48%. 3) The head and neck were the usual sites of the disease. 4) Bone changes occurred in about 24%. 5) Most of the tumor could be removed through early diagnosis to prevent recurrence. bone changes and malignant changes. And at the same time, trough reconstructive surgery, results both functionally as well as aesthetically satisfactory could be achieved.

The serial radiograms has been taken and the nature of the ]esion established as a typical fibrous dysplasia according to the interpreted findings in their images. The author has obtaind the results as follows: 1. Fibrous dysplasia occured at 3 years of age in this case. 2. Familial tendency, traumatic history and endocrine. disturbances: were: not noted in this patient. 3. The serial radiograms revealed a typical fibrous dysplasia encroaching Tight zygomatic bone.

Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed.
