Recently there has been a noted increase in the incidence of traumatic bony gap in long bones due to accidents in industry, high speed traffic accidents and common gunshot accidents. There are several methods to treat traumatic bony gap such as bone graft (autogenous, homogenous and heterogenous), bone transplantation, periosteal osteogenesis and reinplantation of the extruded bone etc. The authors studied 26 patients of traumatic bony gap in the long bones which had been treated by autogenous bone grafting. The results of the clinical observation were as following; 1 The causes were shotgun accidents, vehicle accidennts and explosive accidents. 2 There was bony gap involved in 10 upper extremities and 16. lower extremities. The radius was the most common site in the upper extremity and the femur in the lower extremity. 3. The largest bony gaps were 10.5cm. in the tibia and next were 10.6cm. in ulna and 9.0cm. im humerus. 4. The period of the bony union in these cases was prolonged 1.5~3 times the usual healing period of simple fractures. 5. It was very important to prevent and control infection of the open fractures and to decide the correct time for bone grafting operation after healing of the infected wounds. We did the bone grafting sugery 2 or 3 months later after the infected wounds had been healed. 6 The authors could avoid some complications such as delayed union, shortening of the affected limbs and stiffness of the joints of the affected limbs etc.

Pagets disease has been well known disease in western countries, but it is extremely rare in orient and no case has been reported in Korea yet. It is a chronic osseous disease affecting middle and late life, characterized by progressive skeletal deformities which consist of excessive resorption and abnormal regeneration. We experienced a case of Paget's disease in a 57-year old man with involvement of pelvis, femur and skull, and confirmed with open biopsy.

The technique of the arthroscopic total meniscectomy of discoid meniscus is very difficult. Ikeuchi(1982) reported a technique of arthroscopic total meniscectomy of the lateral discoid meniscus by removal of 2/3 of the anterior part of the meniscus first and then by morselization. The purpose of this paper is to report a technique of arthroscopic total meniscectomy of the lateral discoid meniscus as a whole. During the period from October 1982 to October 1984, we had 12 experiences of arthroscopic total meniscectomy of the discoid meniscus and found good results, that is, little postoperative pain, short period of hospitalization and early restoration of joint motion without physical therapy. Complications are 3 cases of symptomless slight lateral instability and 4 cases of hemarthrosis.

Neurofibromatosis(NF) is a disorder characterized by its relative commonness, variability, and heterogeneity. It is usually expressed as a generalized form, but is rarely localized in a limited part of the body as a segmental form. In 1981, Riccardi classified NF into 8 types and a segmental form (type V) was defined by limitation of cafe-au-lait spots and/or neurofibroma on a given unilateral segment of the body. Recently we came across two cases of typical segmental neurofibromatosis. The First case was a 53-year-old woman with localized neurofibromatosis on the right T8,9 dermatome. The Second case was a 34-year-old man with localized neurofibromatosis on the right T5,6 dermatome. There were no cafe-au-lait spots, axillary frecklings, Lisch nodules or a family history in both cases. We report these rare cases with a literature review.

BACKGROUND: Pyogenic granuloma(PG) is a common lesion of the skin and mucous membranes. The gingival lesion developed during pregnancy termed epulis gravidarum is identical to PG. Many articles have appeared in the literature pertaining to this lesion and its putative relationship to the hormonal changes of pregnancy. Several clinical features such as association with oral contraceptive use and regression after delivery, suggest that PG may be a hormone-sensitive lesion. OBJECTIVE: Our aim was to determine whether estrogen or progesterone might affect the development of PG. METHODS: We performed immunohistochemical staining by using a monoclonal antibodies to estrogen receptor(ER) and progesterone receptor(PR) in 15 PG(pregnant women; 4 cases, non-pregnant women; 5 cases, and men; 6 cases). RESULTS: All 15 PGs were negative for ER. However, for PR, the degree of staining was different according to the patient group; pregnant women(3 cases[75%]: weak positive, 1 case[25%]: strong positive), non-pregnant women(3 cases[60%]: weak positive), and men(6 cases[100%]: negative). CONCLUSION: Our results suggest that estrogen or progesterone may not directly involve in the formation of these lesions. Further studies are needed to determine whether the other factors are related to the pathogenesis of PG.

The purpose of this study is to compared and analyze the shade changes(deltaE)about In-Ceram(R),IPS-Empress(R),OPC(R) by using of the spectrophotometer arising from initial status and before and after cementation of the resin cement mounted on the metal core. We used a couple of statistics such as 'One-Way ANOVA'and Multiple Range Test. We could be able to verify significantly what is being discussed here up to 95%. The results drawn from our research are as follows: 1. At the time of our experiments regarding the initial shapes of all-ceramic and mounting status of all-ceramic on the metal crown(deltaE1), and a comparison of mounting of all ceramic on the metal crown with all-ceramic cemented on the metal core(deltaE2), at the time of shade change of initial shapes and after we cemented on the metal core. (1) no significant difference among all-ceramics was found. (2) no particular difference was found regarding the In-Ceram(R) (3) a significant difference between the deltaE1 and deltaE2 regarding the IPSS-Empress(R) was found (P<0.05). (4) a significant difference between the deltaE1 and deltaE2 regarding the OPC? was found (P<0.05). 2. When we compared the shade changes (deltaE) resulted from before and after the cementation on each of the parts involved of some all-ceramic . we could be able to find shape change increase from incisal third, middle third, and cervical third in that order in In-Cream(R)(spinell), IPS Empress(R) and OPC(R) all. In addition , we could be able to find a siginificant difference between cervical third and incisal third, middle third. (P<0.05) From what we have just seen, we might conclude that there is a significant shade change difference before and after the cementation with respect to IPS-Empress(R)and OPC(R). In addition, we could also be able to find more shade change difference at the cervical third rather than incisal third and middle third depending on the parts involved.

BACKGROUND: There is concem about the rising incidence of skin cancer. However, few articles have reported the change in the clinical and epidemiological aspects of skin cancer. OBJECTIVE: We performed this study in order to clarifiy the recent changes in cutaneous premalignant and malignant lesions. METHODS: A statistical analysis was made using 101 cases of cutaneous premalignant lesions and 205 cases of ma]ignant tumors out of a total number of 20,175 new outpatients that visited the Department of Dermatology at the Seoul National University Hospital during a 6 year period(1990-1995). RESULTS: The frequency of premalignant lesions was 0.50% and that of malignant tumors was 1.02%. The frequency showed an increasing tendency compared to previous reports. In the premalignant lesion cases, actinic keratosis was most common and represented a figure of 82.2%. Among the malignant tumors, basal cell carcinoma was most frequent at 24.4%. Age, sex and anatomical site distribution of basal cell carcinoma, malignant melanoma was no different. The mean age of squamous cell carcinoma was greater than in previous reports and main preceding lesions were actinic keratosis and cheilitis. The frequency of lymphoma was markedly increased but the reason for this remains to be determined. CONCLUSION: Our findings showed the continous increasing incidence of skin cancers and emphasize the need for public eduacation, early diagnosis and proper treatment.
