The extensive traumatic wound has posed a serious problem to the surgeon. Various drugs and dressing methods have been used for this kind of wound but there has been no ideal method. The pigskin xenograft was used initially for the treatment of burn wound. The salutary effect of porcine xenograft are the stimulation of growth of healthy granulation tissue, as well as epithelial borders, inhibition of bacterial growth and pain relief. We have performed porcine xenograft in 20 cases having extensive traumatic wound with skin defect from January 1981 to February 1982. The results obtained are as follows: 1. Protect large open wound until autograft are available. 2. Alleviate pain in the wound. 3. Promote granulation tissue growth which is needed for early autograft. 4. Protect the exposed wound areas (bone and tendon) from infection. 5. The healing time of the wound depended upon the severity and the state of underlying tissue in the wound rather than wound size.

BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

Auditory agnoia is defined as a disability to recognize spoken languages and/or nonverbal environmental sounds and music despite adequate hearing while spontaneous speech, reading and writing are preserved. Usually, either bilateral or unilateral temporal lobe especially transverse gyral lesions are responsible for auditory agnosia. Subcortical lesions without cortical damage else rarely causes auditory agnosia. We pesent a 65-year-old right-handed male with generalized auditory agnosia caused by bilateral subcorcal lesions. After the two attacks of stroke, he could not understand and recognize spoken words and meet of non verbal sounds. Repetition and dictation were impossible but spontaneous speech was fluent and comprehensible even though mild paraphasic error was noted. Naming was normal. He could understand and read aloud the written words and phrases. Clinical examination of the ears was normal as were audiometry and brainstem auditory evoked potential. Brain magnetic resonance images showed a large cavitary lesion due to an old intracerebral hematoma in right subcortical temporoparietal lobe with preserved superior temporal gyrus and a slit like subcortical lesion in the left insula.

Flexor tendon injuries have long been considered one of the Problem areas for hand surgeons because of occasional unsatisfactory results of treatment. The authors reviewed 111 cases of flexor tendon injuries which were treated by primary repair in the Department of Orthopedic Surgery, Kyungpook National University Hospital for about 6 and a half years from Jan. 1977 to Aug. 1977. The results obtained were as follows; 1. Sex ratio between male and female was 4. 3: 1. 2. Age distribution showed the most frequent occurrence between 21 and 30 (38.7%). 3. Most of the patients were injured by glass (67.5%) and at the wrist level or proximal to it. 4. Average follow up period was 6 months and over-all end result was satisfactory in 83.9% by the Klienert criteria. 5. 9 cases of the 10 flexor pollicis longus only injured showed satisfactory result by the arbitrary criteria based on active flexion range of thumb i-p joint and functional difficulties in the daily living.

A lymphangioma, which is analogous in some ways to hemangioma due to a common origin, develop and grow in identical fashion and show certain common features in response to treatment, is a benign tumor composed of lymphatic tissue. But lymphangiomas are much less common than hemangiomas in frequency and most of these lesions are usually present at birth. Most of these lesions are found in the neck, few are located in the axilla and the remainders are scattered throughout the body. Soft tissue hyertrophy of the thenar eminance and proximal portion of index finger of left hand due to congenital lymphangioma, 7-months male baby, treated by surgical resection is presented with a review of the literature.

BACKGROUND: The anterior spinal artery infarction constitutes a classical syndrome of vascular myelopathy. The causes of the anterior spinal artery syndrome are various, but most episode probably occur as the result of atherosclerosis or dissection of the aorta and its branches. However, few cases reported developed with spinal structural abnormalities. CASE: A 65-year-old man presented with sudden paraparesis. There was no evidence of hypertension, diabetes and smoking. Motor weakness was more prominent on the left side and progressed. Loss of pain and temperature senses were shown at the level of 71 with preservation of touch, joint perception and vibration senses. The DTR's of legs were depressed and extensor toe signs were presented. A C-spine MRI showed high signal intensity on 72 weighted image and low signal on 71 weighted image(C6-71) with cervical spinal stenosis at the C4-C7 spinal level and mild cervical disc protrusion (C6-C7, C7-T1). After three months later, follow up cervical MRI showed somewhat decreased size of high signal intensity on 72 weighted image and more prominent low signal on 71 image. DISCUSSION: In our case, we could not find any usual cause of anterior spinal artery infarction. However only cervical spinal stenosis associated with mild cervical disc protrusion was present. In stenotic cervical canal, the anterior spinal artery can be more vulnerable to extrinsic compression and the infarction may early develop with insignificant trigger event, such as disc protrusion. We concluded that the ischemic change of anterior two thirds of cervical spinal cord might develop due to the compression of the anterior spinal artery by cervical stenosis and mild cervical intervertebral disc protrusion.

BACKGROUND AND OBJECTIVES: Percutaneous intervention has become an established technique in the treatment of peripheral arterial obstructive disease. This study was performed to evaluate the procedural success and long-term outcome of percutaneous intervention of the superficial femoral artery (SFA), and to determine the factors that influence the long-term outcome. SUBJECTS AND MEHTODS: Eighty-eight consecutive lesions, in 76 subjects (mean age 65) with chronic lower limb ischemia and SFA obstruction, diagnosed with angiography were included in this study. The angiographic success was defined as residual stenosis <30% and the clinical success as an improvement by at least one clinical category. The clinical patency was defined as an absence of symptom recurrence and target lesion revascularization during the follow up period. The predictors of the outcome were also determined. RESULTS: Balloon angioplasty only was performed in 39 lesions and thrombolysis only in 2, whereas stenting was performed in 47 lesions. Seventy four of the 88 attempts (84%) at recanalization were angiographically successful, while 73 (83%) experienced clinical improvement. The twelve month patency was 67%. Critical ischemia (versus intermittent claudication)(relative risk 4.2, p=0.020) and renal failure (relative risk 4.1, p=0.016) were independent negative predictors of the patency. CONCLUSION: Percutaneous intervention of the SFA yielded a high procedural success rate, with an acceptable long-term outcome. Symptoms of critical ischemia and renal failure were predictive of a low long-term patency.
