Reduction of displaced diaphyseal fractures of the radius and ulna in adult must be nearly anatomical for restoration of mormal function. Most of the fractures require operative management, and various methods of open reduction and internal fixation have been recommended. Because we believe that anatomical reduction followed by rigid internal fixation provides the most satisfactory results for these injuries, dynamic compression plating method is frequently used in our hos pi tal. We studied 52 diaphyseal fractures of the forearm bone in 33 patients treated at the S.R.C.H. from May 1980 to December 1985. Of the 33 patients, 20 had fractures of the radius and ulna; 6, fractures of the radius only; and 7, fractures of the ulna only. The fractures of both bones were treated with plate and screws in 19 patients. In another one, the ulna was treated with plate and screws and the radius was treated by screw fixation only. The results were as follows: l. Of the 52 fractures, 51(98.1%) were united after the initial operation within 23 weeks. 2. The average time for radiological union of the fracture, excluding those complicated by infection or non-union, was 11.1 weeks for 24 radii and 10.9 weeks for 25 ulnae. 3. Only one patient(3.0%) was complicated by infection and only one(1.9%) non-union of radius occurred. 4. The functional results were excellent or satisfactory in 25 patients(83.3%). 5. We have found that in adults the auto compression plating is a successful method for the diaphyseal fractures of the forearm.

The management of penetrating injuries of zone II of the neck presents a difficult problem. The difficulties are due to the close anatomical relationships between the many vital structures in the neck and to the insidious nature in which some of the injuries may present themselves, for example, esophageal lacerations. If a significant injury is overlooked, the consequences may be dire with severe complication and mortality. Two management strategies have been developed for coping with these difficult injuries : (1) mandatory exploration of all injuries penetrating the platysma, and (2) a selective approach with neck exploration being performed based on clinical and investigative findings. The aim of this study was to review the clinical characteristics of and the various treatment protocols for II penetrating injuries of the neck. We reviewed retrospectively the medical records of 38 patients who were admitted to and treated at Yongdong Severance Hospital, College of Medicine, Yonsei University, due to penetraing injuries of the neck from Jan. 1990 to Dec. 1996. Twenty-three of the 38 patients (60.5%) underwent immediate operative exploration. In 13 of these patients, the exploration produced positive findings (56.5%), and in 10, the exploration produced negative findings (43.5%). Following neck exploration, 13 patients presenting acutely were found to have 21 injuries. The predominant injuries were vascular followed by neurologic and then respiratory. Eight of the 11 patients (73%) with positive clinical findings were found to have injuries at exploration, and 5 of the 12 patients (42%) with no clinical signs were found to have injuries (p=0.0432). Three of 4 patients (75%) with positive CT scan findings were found to have injuries at exploration and 4 of the 8 patients (50%) with no CT scan findings were found to have injuries (p=0.0455). The complication rate and the performance rate of CT scan were not statistically different between patients with a negative neck exploration and patients with conservative management. The duration of hospitalization was an average of 6.2 days for those patients with a negative neck exploration and 4.1 days for those patients with conservative management (p=0.0022). There was no mortality. In conclusion, it is possible, by careful physical examination and CT scan, it will be possible to reduce the rate of negative neck exploration without risk to those patients who need immediate surgery.

BACKGROUND: The management of penetrating neck injuries presents a difficult problem. Although many authors have stated that surgical exploration should be mandatory for all neck injuries that penetrate platysma, recent reports from many centers now claim selective exploration. The aim of this study was to review a policy of selective neck exploration based on clinical presentation, anatomic location, and the result of diagnostic studies. METHOD: We reviewed retrospectively medical records of 66 patients who were admitted and managed at Yongdong Severance hospital, Yonsei university college of medicine due to penetrating neck injuries from Jan. 1990 to Dec. 1996. RESULTS: Forty-one patients(62%) were underwent immediate neck exploration, while the remaining 25 patients(38%) were admitted and observed. Three had esophagoscopy, four had esophagogram, and three had direct laryngoscopy, all of which revealed normal result except one patient had blood tinged larynx on laryngoscopy. Results of 12 neck explorations(29%) were negative. There was no delayed diagnosis during conservative treatment. There was no mortality. CONCLUSION: We concluded that selective exploration of penetrating neck injuries is both safe and resonable.

BACKGROUND: After multiple trauma, blood coagulation activity is enhanced and fibrinolytic activity is suppressed by overproduction of plasminogen activator inhibitor-1 (PAI-1). Intermittent sequential pneumatic compression (ISPC) is an effective method to prevent deep vein thrombosis. Its action is explained by the mechanical effect on blood flow, as well as by the enhancement of fibrinolysis by the reduction of PAI-1. The aim of this study was to determine the effects of ISPC on coagulation and fibrinolysis after multiple trauma. METHODS: Thirty-nine trauma patients were either treated with ISPC (ISPC group, 20 patients) or without ISPC (control group, 19 patients). We measured the plasma levels of the thrombin antithrombin III complex (TAT), the plasmin alpha 2 plasmin inhibitor complex (PIC), the tissue plasminogen activator (t-PA), and the plasminogen activator inhibitor-1 (PAI-1) on admission and at 1, 2, 3, 6, 12, and 24 hours after admission. RESULTS: The TAT was higher than normal in both groups, with no significant difference between the two groups throughout the study period. The PIC level of ISPC group was significantly higher than that of the control group. In the ISPC group, the PIC level increased gradually, reaching a peak at 3 hours and decreasing thereafter. In the control group, the PIC level increased to a peak level at 2 hours. The TAT/PIC ratio dropped in the first two hours and increased at 3 hours, dropping again thereafter. In the ISPC group, the ratio dropped gradually without an intermittent fluctuation. At 3 and 6 hours, the control group showed a significantly greater ratio compared to the ISPC group. PAI-1 was higher than normal in bothgroups, with a significantly lower level in the ISPC group from 2 hours to 24 hours. For the t-PA level, no difference was noted between the two groups, with the peak level occurring at 1 hour. The PAI-1/t-PA ratio was significantly greater in the control group from 2 hours to 12 hours than in the ISPC group, but the difference was not significant at 24 hours. CONCLUSIONS: In multiple trauma patients, ISPC does not seem to affect coagulation, but enhances fibrinolysis through suppressed PAI-1 production. This effect of ISPC may be maintained for 12 hours.

Auricular arterio-venous malformation(AVM) is relatively rare and few have been reported in the literature. Two cases, presented here showed pulsating lesions of anterior and posterior auricular or even retroauricular mastoid area. They caused irregular macro and prominent ear compared with the opposite normal ear. After embolization of feeding arteries to the arteriovenous malformations, skin and subcutaneous masses were completely removed and grafted with full thickness skin: one was removed one stage and the other underwent a two stage operations. There were no evidence of recurrence for more than 2 years follow up and esthetic results were promising.

Necrotizing colitis associated with carcinoma of the colon, Known also as obstructive colitis, is a disordercharacterized by anulceration and inflammation of the colon proximal to an obstructive lesion, especiallycarcinoma of the rectosigmoid colon, and in rare instances, leads to actual gangrene of the colon. The authorsanalysed radiologic findings in four cases of necrotizing colitis associated with carcinoma of the colon. Bariumenema disclosed mucosal edema, nodular filling defects, irregularity of the colonic controur and typicalthumbprinting appearance of involved colon proximal to an obstructing carcinoma of the colon. The mechanism ofnecrotizing colitis was briefly reviewed.

Condyloma acuminatum, a benign disease caused by a filtrable virus, occurs predominantly in the perianal andgenital areas. The lesions are noninvasive but are subject to recurrence. In rare instances, a more aggresive formof this disease, known as "giant condlyloma acuminatum" or "Buschke-Lownestein tumor", occures. In this form,infiltration of the lesion into surrounding structures takes place. This tumor has been reported to occurprincipally in the genitourinary tract. The authors experienced a cases of giant condyloma acuminatum originatingfrom rectum in 67 years old male patient which recurred 3 months after electrofulguration.

We retrospectively analyzed 17 necrotizing pancreatitis patients who were treated surgicaly at the Department of Surgery, Yonsei University, from April 1983 to October 1996 in order to identify that the presence of intra-abdominal infection. The mean age was 46.5 years old. There were 11 male patients and 6 female patients. The most common etiology was alcohol and trauma. The mortality rate was 6%, for which etiology was alcohol. We grouped the patients into three groups, which is the infected, non-infected, and no culture performed. There were 6 non-infected patients, 6 infected patients, and 5 no culture performed patients. The most frequent infecting organism was E. coli. Others were E. faecalis, P. aeruginosa, K. pneumonia, and E. cloacae. There were 6 non-infected patients. The complication rate was 50% in infected cases, the 67% in non-infected cases, and 80% in no culture performed cases. In non-infected patients, Ranson's criteria, APACHE II score, total transfusion of packed red blood cell, and hospital stay were greater than infected patients. The ICU stay was longer in infected patients. However, there were no significant differences among the three groups. The basic operation procedure was necrosectomy and drainage. Others were cholecystectomy, segmental resection of colon, etc. We concluded that the presense of intra-abdominal infection should not be the sole determinant for intervention, so, the early and aggressive surgical intervention in case of symptomatic pancreatic necrosis is more beneficial irrespective of infection.
