In children, the supracondylar fractures of the humerus are common in elbow region, and often associated with various complications and problems in treatment (ie,Volkmann's ischemic contracture, cubitus valgus or varus deformity, rotational deformity). The results of reduction can be measured by Baumann's angle, carrying angle, trochlea-capitellum angle, and displacement of distal radial styloid process on radiological study. So we have made experiments on the process which various three dimensional displacements reflected into two dimensional Baumann's angle and humerocapitellar angle. And we investigated the process of rotation, through various radiological studies by means of molded models of humerus. The results were as follows:l. In experiments, AP & lateral X-ray studies showed no change in rotation of proximal segment of fracture with fixed distal segment of fracture. 2. On the other hand, AP & lateral X-ray showed significant change, in rotation of proximal fracture segment with distal segment of fracture. 3. Supracondylar rotation angle(S.R.A.)depicted as the ratio of the length of proximal fracture width minus that of the distal fracture width in lateral view, to the length of distal fracture width in AP view minus that of the distal fracture width in lateral view. 4. According to the modified Mitchell result, S.R.A. to the result of treatment was average 7.6 degree in excellent group, 15.2 degree in good group and 29.3 degree in unsatisfactory group.

We report a case of morphea profunda in a 21-year-old male who had diffuse brown sclerotic plaques on his extremities. Laboratory findings showed peripheral eosinophilia and an increased titers for anti-DNA and anti-nuclear antibodies. Histopathologic findings showed diffuse fibrosis and a thickening of the lower dermis and subcutaneous tissue. He has been treated with hydroxychloroquine 400mg per day and the sclerosis of the skin improved.

A clinical observation of the nail pigmentation change was made on 200 patients receiving cancer chemotheray who were seen at; the Department of Internal Medicine, Seoul National University Hospital, from January through May, 1986. The results were as follows: l. Among the 200 patients, 118 cases(59%,) showed nail pigmentation changes. 2. The patterns of nail pigmentation change were as follows: Parallel transverse band(70 cases 59.3%), longitudinal pigmentated band(32 cases, 27. 1%), brown arc(25 cases, 21. 2%), Proximal black pigmentation(10 cases, 8. 5%), diffuse pigmentation(5 cases, 4.2%), parallel transverse white line(5 cases, 4.2%), half and half nail(3 cases, 2. 5%), pigmentations with transverse white band(1 case, 0. 8%). 3. Various cambinations of nail pigmentation pattern were found in 33 patients (28. 0%). 4. 11 cases of the nail dystrophy with nail pigmentation change were observed: Longitudinal ridge(7 cases), transverse groove(3 cases), wavy transverse fissure (1 case).

A clinical observation of cutaneous complications was made on 200 patients receiving cancer chemotherapy at the Department of Internal Medicine, Seoul National University from January through May, 1986. The results were as follows: 1. Among the 200 patients, 191 case(95. 5%) showed cutaneous complications 2. The cutaneous complications included the following; hyperpigmentation(14l cases, 70. 5%), alopecia(138 cases, 69.4%), nail change(118 cases, 59.0%), mucositis(47 cases, 23.5%), dryness of the skin(40 cases, 20.0%), seborrheic dermatitis(24 cases, 12. 2%), increase of seborrheic keratosis(11 cases, 5.6%), folliculitis or acneiform eruptions(9 cases, 4,5%), melasma(6 cases, 3.0%), gynecomastia(3 cases, 1.5%), vessel hardening or dimpling(3 cases, 1.5%), radiation recall(2 cases, 1.0%), hyperhydrosis(2 cases), photosensitivity(1 case, 0.5%), tissue necrosis(1 case), facial flushing(1 case), purpura(1 case) and obesity(1 case), 3 Steps were taken to determine the chemotherapeutic agents causing these cutaneous complications, though in some cases it was difficult in determining exaetlr which chemotherapeutic agent was the cause of the observed cutaneous complication.

BACKGROUND: Although actinic keratosis and Bowens disease ar considered as carcinoma in situ, most of them are biologically benign and dont progress to invasive squamous cell carcinoma. It is little known why they take the benign courses and which factors are involved in the tumorigenesis. Keratoacanthoma, self-regresi;ing benign tumor, may be sometimes or fused morphologically with well-differentiated squamous cell carcinoma. So it is necessary to find a useful marker to help us distinguish them. OBJECTIVES: We performed this study to gain a better understani ling of biologic behaviour and tumerigenesis of epidermal keiatinocytic neoplasms. METHODS: We investigated the expression of p53 protein and priliferating cell nuclear antigen (PCNA) by an immunohistochemical method on the formalin-fixed, araffinembedded tissue specimens of epidermal keratinocytic neoplasms. RESULTS: Fourteen out of 20 cases of squamous cell carcinoma(70.0%), 14 out of 22 cases of actinic keratosis(63.6%), and 13 out of 20 cases of Bowens disease(65.0%) showed p53 protein expression, but keratoacanthoma was negative. All the tumors studied sho ved significantly increased numbers of PCNA-positive eells when compared with normal epidermis and characteristic distribution pattern. of PCNA-positive cells. Most cases of actinic keratosis exhibited the basal dysplastic pattern, but Bo wenoid variants showed diffuse dysplastic pattern. Karatoacanthoma revealed the marginal pattern and Bowens disease showed the diffuse dysplastic pattern. Well-differentiated squamous cell carcinoria showed the basal dysplastic pattern, while poorly differentiated squamous cell carcinoma revealed d ffuse dysplastic pattern. CONCLUSION: Our results suggest that p53 mutation is a common and early genetic change in the epidermal tumorigenesis and may be used as a good marker for malignan transformation, but it does not seem to correlate with the biollagic behavior or prognosis of epidermal neoplasms. PCNA, which is considered as a proliferation-relaited marker, was expressed with chavaceristic distribution patterns according to the type of tumors, but the frequency of PCNA expression is unlikely to reflct the malignant potential of epidermal neoplasms.
