Calcaneus was the most commonly involved bone among the tarsal bone fracture. Many different methods have been tried for the treatment of fractures of the calcaneus in order to search for better results. But there is no general agreement on the treatment of the fracture of the calcaneus, especially involving the subtalar joint. From Jan. 1986 to Jan. 1990, 25 feet in 20 patients of calcaneal fractures involving the subtalar joint were treated by closed reduction & percutaneous pinning at the Dept. of Orthopedic Surgery, Chosun University Hospital and the results were as follows; 1. Of these intra-articular fractures, 15 fractures were tongue type and 10 fractures were joint depression type by Essex-Lopresti classification. 2. According to the Salama unit system, the results of treatment were excellent or good in 11 cases of 15 tongue types and 6 cases of 10 joint depression types. 3. The results were excellent in which reduction is achieved near anatomical reduction. 4. Even if the joint depression type fracture which is not severely comminuted, the treatment with closed reduction & percutaneous pinning is thought to be good method.

Authors retrospectively analyzed the CT findings of cystic tumors of the mediastinum in surgically confirmed13 cases at Seoul National University Hospital during the recent 3 years from August 1980 to August 1983. Theresults are as follows: 1. Among 13 cases, bronchogenic cyst and cystic teratoma were 4 cases respectively,pericardial cyst were 2 cases, and thymic cyst and cystic hygroma was 1 case respectively. 2. CT No. of 4bronchogenic cysts was in the range of 12-112 HU, 3 cases among them had thick-walled capsules. CT No. of 4 cysticteratomas was in the range of

The tibial plafond fractures result from an axial compression snd rotational forces causing variable degrees of metaphyseal disruption, articular damage, and malleolar displscement. It is relatively uncommon but a most difficult fracture to manage. It has been treated in a number of manners, but the best results have been occurred when stable internal fixation is accomplished using plates and screws. Basic steps in reconstruction are restoration of anatomic length of the fibula with plate fixation, reconstruction of the tibial articular surface, cancellous bone grafting of the metaphyseal defect and buttress plating of the distal tibia. The suthor analysed the 20 cases of the tibial plafond frsctures in 17 patients, which were trested at the Department of Orthopedic Surgery, Paik Hospital, Inje Medical College from Jsnuary 1983 to March 1987. The longest durstion of followup was 2 years and 4 months and shortest one was 6 months, and the aversge was one year. The results were as follows : 1. Among the 17 patients, male were 16 and female was one. 2. The major causes of injury were a fall from a height. 3. The most frequent type of fracture was type C by Ruedi and Allgower classification. 4. Regardless of the method of trestment the type A and B were in good and fair result, but the type C were fair in 4 cases and poor in 8 cases. There were 7 cases of snkle fusion in poor group. 5. It is important to remind the basic steps in reconstruction and applied in sn individual csse especially in type C. If anatomic reconstruction of the joint surface can be restored and stable fixation achieved, esrly motion of the ankle joint is made possible. This early motion reduces stiffness of the ankle and win yeild the most sstisfying result. But the anatomic reduction of ank1 joint is difficult to be obtained in each case especially in type C and may consider an ankle fusion.

Subcutaneous fat necrosis of the newborn is an uncommon disorder characterized by firm b-cutaneous plaques and nodules usually appearing shortly after birth. It runs a relatively be, n course and may completely resolve in a few months without any recurrence. We report a case of subcutaneous fat necrosis in a 15 day-old male suffering from severe p inatal asphyxia and hypoxic cardiomyopathy, who presented with indurated subcutane s nodules and plaques on the both shoulders and the back. Histologically the subcutaneous fat showed focal necrosis with needle-shaped clefts, lymphohistiocytic infiltration and foreign body reactions consistent with subcutaneous fat necrosis of the newborn. In our patient, compromised cardiac output due to cardiomyopathy might have aggravated hypoxic condition and it could be speculated that cardiomyopathy-induced systemic hypoxia gave rise to hypothermia of the skin as a result of peripheral vasoconstriction. This report presents a causal relationship of cardiomyopathy and subcutaneous fat necrosis of the newborn.

OBJECTIVE: The purpose of this study was to evaluated the effects of alcohol on neurocognitive function, psychomotor performance and subjective response in healthy Korean adults with different ALDH2 genotypes. METHOD: A total of 24 males, half with active ALDH2*1/2*1 and the other with inactive ALDH2*1/2*1, was selected through genotyping using restriction fragment length polymorphism. In a double-blind, placebo-controlled cross-over design, each subject consumed 0.5g/kg dose of alcohol, given as a mixture of 40% vodka and orange juice, and placebo(orange juice) on two separate occasions on an average of weekly intervals. The blood alcohol concentrations(BACs) were measured using a breath analyzer at baseline and at 30, 60 minutes after drinking. P300s were measured at baseline and at 30 minutes after alcohol and placebo intake. Vital signs and psychomotor performance[Critical Flicker Fusion Threshold(CFFT), Choice Reaction Time(CRT), Digit Symbol Substitution(DSS)] were measured at baseline and at 60 minutes after alcohol and placebo intake. Subjective responses were measured at the end of the study. The statistical analysis focused on whether there were any differences between groups with different ALDH2 genotypes. RESULTS: The major results are as follows. 1) BACs in inactive group were overall equivalent to those in the active group. Only in terms of time, BACs were significantly higher overall at 30 minutes than at 60 minutes after alcohol intake. 2) Pulse rates were significantly increased after alcohol intake compared with placebo, and the increase was greater in the inactive than in the active group. 3) P300 latencies in leads Fz(frontal), Cz(cental) and Pz(parietal) were significantly increased after alcohol intake compared to placebo, and the increase was greater in the inactive than in the active group. P300 amplitudes in leads Cz and Pz were significantly decreased overall after alcohol intake compared to placebo. 4) Compared with placebo, alcohol produced significant effect on the psychomotor performance : impairment in the inactive group, improvement in the active group. 5) Compared with placebo, alcohol significantly induced a negative or an intense effect on the subjective responses in the inactive group, but little negative and even a somewhat positive effect in the active group. CONCLUSIONS: These results suggest that ALDH isozyme variance might be an important factor to determine the effects of acute dose of alcohol on the various psychobehavioural functions and also to determine the alcohol use pattern and to predict the future development of alcohol overuse and/or abuse.

The purpose of this study was to investigate the variations of the skeletal and dentoalveolar dimensions in relation to vertical facial patterns. Lateral cephalogram of 200 cases (100 cases of male and 100 cases of female, average age of which was 23.2 years) were traced and some measurements of skeletal and dentoalveolar dimensions were measured. The ratio of UAFH/LAFH was employed to classify the samples into groups of excess and short lower anterior facial height. And the comparison between two groups were taken statistacally. The following results were obtained. 1. The dentoalveolar height, lower anterior facial height, lower gonial angle, and FMA in the excess-lower-anterior-facial-height group were significantly larger than those in short-lower-anterior-facial-height group. 2. The dentoalveolar height, ramus height, and Jarabak ratio in the male subjects were significantly larger than those in the female subjects. 3. The UAFH/LAFH ratio showed a significant correlation to upper, lower facial height, AUDH, PUDH, ALDH, PLDH, Lower gonial angle, FMA, and Bjok`s Sum.
