Reactive perforating collagenosis, first described by Mehregan et al in ]967, is a skin disorder characterized by transepidermal eliniination of altered collagen fibers. This rare disease appears as recurrent, umbilicated, crusted papules in response to minor trauma. We report here a case of reactive perforating collagenosis in a 21-year-old man. Examination of the skin revealed a number of centrally umbilicated, asymptomatic papules filled with keratotic plugs in various development and regression. The lesions were distributed on the dorsa of the hands, face, and neck. The biopsy spccimen showed a few of thin bundles of collagen which v ere extruded from the dermis through the atrophic epidermis and the turinels within the epidermis, reaching the buttom of the plug.

The authors reviewed 17 patients with radial nerve palsy complicating fracture of humerus who were treated at the Department of Orthopedlc Surgery, St. Mary's Hospital Catholic Medical College, for past 3 years from Jan. 1974 to Dec. 1976, and the following results were obtalned. 1. The ratio of male to female in 17 cases with radial nerve palsy was 4 to 1, and In patients within the first decade the ratio was same (1:1). But those in the 3rd and 4th decade showed high incidence of palsy. 2. Among 113 humerus shaft fractures, 17 cases (15.0%) complicated the radial nerve palsy; among 17 cases the middle shaft fractures were 15, lower 2, none in the upper third. 3. The radial nerve was the most vulnerable to injury at the middle third of the humerus, especially when there was comminution of fracture. 4. The incidence of radial nerve palsy in closed fracture (102 cases) was 13.7% (14 cases), and 27.2% (3cases) in open fracture (11 cases). 5. By early surgical exploration the practlcal cause of radial nerve palsy in 9 cases were found; 2 cases by bruise, 2 by interposition, 2 severance of nerve, one stretching, one impaled, and one unknown. 6. There were no signiflcant correlation between the type of nerve damage and the degree of its recovery, and between duration of paralysis since onset and its prognosis. 7. Of the 17 cases with palsy, complete recoveries were obtained 11 cases, 5 incomplete, and no recovery in one.

A clinical study of traumatic amputation by railroad accidents was made an 124 patients with 154 amputee, who had been treated at Department of Orthopaedic Surgery, National Seoul Hospital, during the 4 years period from January 1976 to December 1979. The results of this study are as follows: 1. The ratio of male to female was 9 to 1. The 3rd decade of age group showed the hightest number of accident causalties, as much as 37.1%. 2. Causalties showes a maximum during the sprlng (37.1%) and a minimum during winter. 3. The most common injured sites of the amputee were B–K in 44 cases among 154 cases of the amputee. 4. Considering the number of the multiple amputee in 26 casee among 124 cases, frequently they developed in 2 sites with 22 cases, 3 sites with 4 cases. 5. The frequent fracture sites with combined amputation were 18 cases of the pelvic bone, 12 cases of femur in amputation of the lower extremity. 6. Our methods of treatment were debridement, debridement and primary skin closure, debridement with open amputation, circular amputation, closed amputation with skin graft, and closed amputation. 7. The major complications were phantom limb in 108 cases (70.1%), infection in 44 cases (28.6%). 8. The most frequent infectious agent was pseudomonas (16 cases).

The femoral neck fracture having concomitant fracture of the femoral shaft occurs predaminantly in young man and have known to associate the serious complications. One of such factures is sometimes overlooked and is possibly due to a more obvious nature of the shaft fracture than that of the ipsilateral neck. Six cases of this type of combined fractures in ipsilateral femur are reported with the review of 1 iteratures. In six cases of the femoral neck fractures, three which were unrecognized at initial examiaation in early phase, resulting in serious residue as much as deformity and avascular necrosis of the femoral head, and other three were recognized in early at initial examination healed in good anatomic position and in due time. Through this observation it is stressed that early discovery and adaquate treatment of the fracture is the only solution to minimize the sequelae.

In order to study the cerebral lateralization of the affective response induced by music, the authors chose healthy, right-handed, male students and several pieces of tape-recorded music eliciting either positive or negative affect were given to the left ear to one group and to the right ear to the other. The affctive responses were subjectively measured by subjects after each music by means of the Visual Analogue Scale to compare between the two groups. The results were as follows; 1. Pleasant and comfortable music elicited significantly greater affective response in the left-ear group compared to the right-ear group. 2. After disharmonious and unpleasant music, no difference in the degree of affective response was noted between the two groups. From the above results and a survey of the previous literatures on the subject, the authors suggest that the cerebral lateralization of the affective response may be determined by the mode of affecteliciting stimuli and/or the variety of the affect involved.

The purpose of this study is to compare the biologic properties of tendon to hone healing and hone to hone healing in knee ligament reconstruction. The lateral 4mm of patellar tendon which was detached from its tihial insertion site either subperiostcally(group I) or with a bone block(group II) was implanted and fixed using pullout method to the proximal tihia. Ten rabbits were killed at each of four time periods (two, four, eight and twelve weeks after the implantation), and the histological and biomechanical characteristics of thc graft healing sites were evaluated. Serial histological analysis of tendon to hone healing group revealed organization of the healing site similar to normal tendon to hone attachment by twelve weeks, while hone to bone healing group demonstrated direct hony union by eight weeks. The tension failure test for the patellapatellar tendon graft - tihia complex revealed that group II had significantly higher values than group I at four and eight weeks. The findings ot this study demonstrated that bone to hone healing has more rapid process than tendon to hone healing, although no significant difference was noted once the healing has matured. We can suggest lhat the duration and extent of postoperative protection of the knee for pntients who had a reconstruction of a ligament using hone - lendon autograft should be longer and higher than lor patients who had a reconstruction using hone - tendon hone autogralf.

BACKGROUND/PURPOSE: Phospholipase A (PLAq) is an rate-limiting enzyme hydrolyzing arachidonic acid from the sn-2 position of membrane phospholipids. In vitro studies demonstrated that the enzyme could be secreted into extracellular mileu by pro-inflammatory cytokines and endotoxin which were reported to have important roles in chronic liver diseases. This study was performed to know whether the enzyme is involved in the pathophysiology of the diseases. METHODS: The subjects were composed of 24 patients with chronic hepatitis B, 26 patients with liver cirrhosis and 14 healthy individuals. The PLAp activities wem measured in the sera of the subjects by detecting radioactivity of "C-fatty acid hydrolyzed from "C-labeled phosphotadylethanolamine by the enzyme. RESULTS: The activities of PLA were increased in the patients with chronic liver diseases, especially in the chronic hepatitis B patients with acute exacerbation and in the decompensated cirrhosis patients. Furthermore, their activities were closely related with the levels of transaminase in hepatitis group and with the levels of serum albumin in cirrhosis group, respectively. CONCLUSIONS: These results suggest that extracellular PLA might be involved in the exacerbution and progression of the chronic liver diseases.

A case of Epidermolysis Bullosa Dystrophica is reported with review of pathogenesis with literatures. Epidermolysis Bulloaa Dystrophica is a rare genetic disease which is characterized by the formation of blister upon the minor trauma or friction to the skin. A 7-year old boy was referred to our dept. in Aug. 1976 because of a severe bullous eruption primarily on his hands and feet. On admission tense bullae were noted on the dorsa of hands and feet which is usually serous but may be hermorhagic tendency. Soon thereafter tbis bullous lesion tend to break down into painful shallow denudation which may leave depigmented scars and milia after healing. Family history was negative for skin disorders.
