2.Open Skin Grafting of War Wounds
The Journal of the Korean Orthopaedic Association 1971;6(4):371-376
During the period from April 1971 to September 1971, 30 young male patients with war wounds sustained in the conflict of Viet Nam were treated by open skin grafting of their wounds at the Orthopedic Servlce of Taegu Hospital. The majority of patients had multiple wounds and most had associated fractures of the long bones. The indication, preoperative preparation, operative technique, postoperative care and results have been described. We believe that this open skin grafting offers the following advantages over other techniques; 1) Graft taken more satisfactorily. 2) Remarkable decrease of operating time. 3) Simplicity of operative technique. 4) Continuous observation of wound healing. 5) Relative safety in using this treatment upon unstable injured limbs and cases with neurovascular deficit because the lesion is free from compression dressing. 6) The grafts tend to be “take” even if there is bleeding or drainage, because it can be carefully rolled out under the direct observation.

PURPOSE: Objective measurements of knee of flexor and extensor strength using isokinetic equipment and function after total knee arthroplasty (TKA) were evaluated until postoperative 12 months. MATERIALS AND METHODS: The control group constituted of 15 persons who were of same age and weight without knee problems. Most of the patients (70%) were operated on both knees simultaneously. The patient group consisted of constituted with 20 patients (34 cases). Isokinetic testing (Cybex) of knee flexor and extensor strength of knee and functional evaluation by HSS score was performed preoperatively and at 3, 6, 12 months postoperatively. RESULTS: The peak torque of the knee extensor and flexor muscle in the patient group was decreased by 17-41% compared to the control group. Especially, the peak torque of extensor was more decreased than flexor muscles. At postoperative 12 months, the peak-torque values of hamstring and quadriceps were able to attain the same strength levels of the preoperative knee. According to the grade of the Hospital for Special Surgery knee rating scales by Insall, 28 cases (82 %) in the patient group could obtain good result at postoperative one year. CONCLUSIONS: Exercises to increase the strength of extensor should be emphasized in the rehabilitation programs after TKA

In an open reduction of the mandibular angle fracture, it is crucial to approximate each fracture segment as closer as possible for the reduction of the healing period. In this case report, we proposed a new technique for the mandibular angle fracture. This was designed to minimize the gap between two separated segments using mini-implants and surgical wires. Mini-implants were placed around the fracture line, followed by wire ligation to minimize the fracture gap. And then internal fixation was easily employed with plates and screws. The advantages of this technique were reduced time for operation, the promotion of healing, rapid functional recovery, and few complications.

The computed tomography (CT) number is closely related to hematocrit level according to many of the previous reports. We measured the CT number in various organs, such as the frontal white matter, basal ganglia, occipital white matter, cerebrospinal fluid, liver, abdominal aorta, spleen, kidney, and psoas muscle. We correlated the CT numbers of the organs with hematocrit levels which were graded into 10% increments (20.0-29.9%, 30.0-39.9%, 40.0-49.9%). Thus the change of CT numbers in various organs according to the hematocrit level was analyzed. The increased CT numbers according to the 10% increment of hematocrit in the frontal white matter, basal ganglia, occipital white matter, liver, abdominal aorta, spleen, and psoas muscle were 1.3, 1.5, 1.6, 3.3, 5.3, 3.8, 2.4 respectively. Even though the CT numbers of the cerebrospinal fluid and kidney were not influenced by hematocrit level the CT numbers in most of the there organs postitively correlated with hematocrit level. Therefore, it was concluded that in the differential diagnosis using CT numbers, the hematocrit level of patient must be taken into consideration.

We report a case of piroxicam-induced photosensitive dermatitis in a 54-year-old female. She had taken oral piroxicam and was exposed to the sunlight on her way home for a few minutes. Several hours after the sun-exposure she developed well-defined, confluent, erythematous plaques and numerous vesicobullae with pruritus and prickling sensation on the sun-exposed areas. A phototest was done on her first visit. The minimal erythemogenic dose (2 J/cm²) of ultraviolet (UV) A was markedly decreased whereas that of UVB was within a normal limit. Visible light irradiation for 30 minutes did not cause skin lesions. Six months after the initial skin lesions, a photopatch test with 1% and 10% piroxicam solution followed by UVA (10 J/cm²) irradiation showed positive responses on both concentrations.

BACKGROUND: We studied the incidence of trauma caused by alcohol related accidents, and the effects that has on the occurrence, the extent, and the outcome to the patient. METHODS: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of january 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were divided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analysed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. RESULTS: The total of the trauma patients, added up to 832 people, 577: male and 255: female. Among this sum, 16 trauma patients were alcohol related(male:127 & female 36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mossy by fast-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer alcohol-related trauma patients. CONCLUSION: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time it the reason for their visit were mossy because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.
