1.The Influences of Arteriosclerosis on the Development and Progression of Diabetic Retinopathy .
Journal of the Korean Ophthalmological Society 1999;40(9):2514-2522
To evaluate the relationship between arteriolosclerosis and diabetic retinopathy, we graded the levels of diabetic retinopathy and arteriolosclerosis and compared each other in 255 patients with non-insulin dependent diabetes. And we also measured serum lipid levels and checked other risk fac-tors for diabetic retinopathy. SPSS was used for statistical analysis. Patients with advanced arteriolosclerosis were at higher risk of severe diabetic retinopathy. And patients with elevated plasma total cholesterol, LDL-C, TG had more severe levels of diabetic retinopathy than whose lipid levels were normal. These results suggested that advanced arteriolosclerosis and elevated serum lipid levels are associated with severe diabetic retinopathy. For preventing visual threatening complications of diabetic retinopathy, the degree of arteriolosclerosis and serum lipid levels should be carefully monitored in the evaluation of diabetic retinopathy.

Intracompartmental pressure of leg was measured by the slit catheter technique in one hundred fifty compartments of one hundred cases; fifty were from healthy young male adults, the others were from tibial fractured patients during three years from March 1983 to Fobruary 1986. The results were as follows; 1. Slit-catheter technique was found as a accurate method for continuous pressure monitoring. 2. The range of normal pressure was from zero to six millimeters of mercury(1.45mmHg±0.85). 3. Tissue pressure was 0–15mmHg(4.03mmHg±1.83) in unaffected side of fractured patients, 4–35mmHg(14.65mmHg±2.05) in affected side of fractured patients.

A case of myxoma of the breast was reported. A 25-year-old woman showed a lump in the left breast which was suddenly enlarged after the delivery of a baby. A tumor measuring 73.53cm was located in the upper outer quadrant of the breast. Fine needle aspiration cytology revealed scattered benign spindle shaped mesenchymal cells with abundant myxoid material. On excision, the tumor was partly solid, partly cystic and multilocular. Each nodule consisted of an abundant mucoid material with a few spindle or stellate mesenchymal cells. Pleomorphism and mitosis were absent. The mesenchymal cells showed immunoreactivities for S-100 protein, smooth muscle actin, and CD34. The myxoid stroma was positively stained with alcian blue and mucicarmine. These findings suggest that constituent cells derive from totipotential primitive mesenchymal cells.

The knee joint is one of the most susceptable joint to ligamentous injury. For good results, it is very important to make an early diagnosis and to give prompt management. The aim of treatment is to restore the ligaments to their previous anatomic position and tension. The authors reviewed 420 cases of ligamentous injuries in 400 patients who were admitted and managed for 6 years from March, 1981 to February, 1987. The results were as follows : 1. The athletic injury was the most commcn cause of injury(55%), and fall-down was next(26%). 2. The most common ruptured individual ligament was the medial collateral ligament. Combined ligament rupture was more common in medial collateral ligament and anterior cruciate ligament. 3. The ruptured sites of the individual ligament were found to be the following ; a) the medial collateral ligament was ruptured most frequently at the femoral attachment(43%), with the superficial layer ruptured in the midsubstance and the deep layer at the femoral attachment; b) the lateral collateral ligament torn at the fibular attachment(51%); c) the anterior cruciate ligament torn at the femoral attachment(39%); d) the posterior cruciate ligament torn at the femoral attachment(64%). 4. Many ligamentous injuries were associated with fracture(44%) and tear of meniscus- (42%). 5. In stress-radiogram, the significance of ligament injuries was present in more than 10 and 10 mm. 6. Excellent and good results were obtained in 94% by non-surgical treatment and in 92% by surgical treatment. 7. Early surgical repair of the ligament within 2 weeks after injury, gave much better result than later repairs.

BACKGROUND: Epidermal grafting using cryotherapy for recipient sites is in widespread use. However the peripheral hypopigmented haloes that occur around the recipient sites require prolon gation of the treatment period. OBJECTIVE: We used a CO2 laser to remove the epidermis of the recipient sites for betteri results. METHODS: We treated lie localized vitiligo patients with CO2 laser to remove t.he epidermis and grafted suction blister rooves. We observed repigmentation and complications 1 month later. RESULTS & CONCLUSIONS : The superiority of this method is demonstrated by the fact 1) all prodedures can be completed on the day of operation 2) the incidence of hypertrophic scar and peripheral hypopigmented halos can be observed.The problems of this method are 1) uneven repigmentation of recipient. sites 2) hyperpigrnentation of recipient sites

The patella is an important component of the extensor mechanism of the knee. It serves to increase the mechanical advantage of the quadriceps muscle by increasing its lever arm. Therefore, if possible, when the patella is fractured, it should be repaired rather than excised. Present surgical techniques for the patellar fractures utilizes principles of anatomic reduction with repair of any associated retinacular tears, rigid internal fixation, and early institution of joint motion exercises. To compare the efficacies of the commonly used wiring techniques, we performed tension tests with transversely bisected patellar models fixed with circumferential wiring, Magnuson wiring, modified tension band wiring and modified tension band wiring combined with circumferential wiring. Also, we reviewed 66 surgically treated patellar fractures from Jan. 1984 to Dec. 1988, when we had given every effort to preserve the patella using modified tension band wiring or modified tension band wiring combined with circumferential wiring. l. According to the results of the tension tests, modified tension band wiring and Magnuson wiring were more rigid than circumferential wiring and the rigidity of modified tension band wiring was much increased when combined with circumferential wiring. 2. Of the 66 cases, 46 cases were treated with modified tension band wiring combined with circumferential wiring, and the remainder were treated with modified tension band wiring. 3. On the whole, good and excellent results were achieved in 87.9% (58 cases). Unsatisfactory results were obtained in 15.0% of cases treated with modified tension band wiring and in 10.9% of cases treated with modified tension band wiring combined with circumferential wiring. 4. Most of the unsatisfactory cases were so severely comminuted that could not be achieved anatomic reduction, rigid internal fixation and early joint motion exercises.

In the assessment of thoracolumbar fractures, computed tomography (CT) is superior to other imaging modalities especially when a more definitive assessment of the posterior elements of the spine or the neural canal is desired. We evaluated 55 patients with acute thoracolumbar burst fractures, and correlated the amount of neural canal impingement (NCI), demonstrated on computed tomographic scans, with each patients neurologic status, level of injury and extent of recovery when neural deficit was present. The results were as follows ; l. Average NCI was significantly higher in cases with neurologic deficits (57.3%) than in cases with no deficit (29.8%). But the range of NCI was much overlapped between the two groups (32-100% with deficits vs. 8-69% with no deficit). 2. In cases with neurologic deficits, average NCI was significantly higher in lumbar spine (75.0%, range; 61-100%) than in thoracolumbar spine (49.2%, range; 32-87%). 3. There was no neurologic deficit in cases with NCI less than 30% in thoracolumbar spine and less than 60% in lumbar spine. 4. In thoracolumbar spine, there was more significant relationship between NCI and patient's neurologic status in T12 than in Ll. 5. The NCI did not directly correlate with the extent of recovery of neurologic deficits when present.
