The herniation of intervertebral disc is possibly diagnosed through the myelography, electromyography, discography or computerized tomography. Among them, the myelography is regarded as the popularized method that helps accurate analysis on the location and pattern of the lesion. The authors have studied 363 cases of herniated intervertebral disc with respect to the diagnostic accuracy of myelographic examination from January, 1982 to December, 1985 at the Department of Orthopedic Surgery and Radiology, National Police Hospital. The results were as follows; 1. The most common age group was 21 to 30 years old and ratio of male and female was 9.7: l. 2. The most common site of the lesion was between L4 and L5 vertebra in myelography. 3. Of the 363 cases which underwent the myelography, 305(84.0%) represented positive findings. 4. Myelographic accuracy was coincided with the clinical diagnosis regarding the location of herniation of intervertebebral disc in 262 cases(72.1%).

Intracerebral hemorrhage is the most serious complication of cerebral arteriovenous malformations (AVM). To identify angiographic characteristics of AVM which correlate with a history of hemorrhage, we retrospectively analyzed angiographic findings of 25 patients with AVM. Nine characteristics were evaluated; these include nidus size, location, arterial aneurysm, intranidal aneurysm, angiomatous change, venous drainage pattern, venous stenosis, delayed drainage and venous ectasia. These characteristics were correlated with hemorrhage, which was seen in 18 (72%) patients of CT or MR images. Venous stenosis (P<.05) and delaved venous drainage (P<.05) well correlated with a history of hemorrhage. Arterial aneurysm and intranidal aneurysm also had a tendency hemorrhage although they did not prove to be statistically significant. Detailed analysis of angiographic finding of AVM is important for recognition of characteristics which are related to hemorrhage and may contribute to establishing a prognosis and treatment planning.

BACKGROUND: The patients visiting the primary care complain of the various symptoms. This symptoms may induce the stress or the reverse. In fact the stress can influence the symptoms and signs. So this study was done for the correlation of the symptoms and signs with stress. METHODS: This study was done about the patients visiting the family medicine department of the one university hospital. We collected the all items that can find in the charts for examining the symptoms and signs, and did the requests pater the patients wrote by themselves. The stress test was Psychosocial well being index to be constructed from the General Health Questionnaire. We tested the study by t-test, anova, chi-square, linear logistic regression. RESULTS: The total study numbers were 351. The stress cut-off point was 63 score. The stress group was consisted of 15 males and 43 females. The meaningful symptoms were headache, dizziness, fatigue, weakness, insomnia, anxiety or depression. The meaningful diagnoses were anxiety or depression, tension headache(p<0.05). The meaningful sociodemographic factors were female, housewife or unemployed, menopause, monthly income below 200 ten thousands won. CONCLUSIONS: It was found that the some symptoms and signs were statistically correlated with stress.

The basic technique for total reconstruction of the microtia was established by Tanzer, who utilized autologous rib cartilages for constructing the auricular framework. In order to decrease the number of surgical stages and to achieve maximal convolution, we employed a surgical procedure with simultaneous three layered costal cartilage grafting for the high profiled auricle, concha formation and lobule rotation. However, we performed ear elevation as an additional procedure for some patients who had decreased helical height due to absorption of cartilage framework or postoperative trauma and who had wanted to wear the spectacles or to have more natural appearance of auriculocephalic sulcus. From August 1988 to October 1997 we had performed surgeries for the ear elevation of 58 patients in 177 patients with total ear reconstruction, using various elevation methods; skin graft, local flap, and local with costal cartilage block. When the ear elevation was performed with skin graft, postoperative contraction of the grafted skin was inevitable. In cases with two skin flaps, it was difficult to stabilize and maintain the correct projection of the constructed ear. So we elevated the reconstructed ear by utilizing a costal cartilage block, two skin flaps to cover the posterior region and skin graft. We conclude that the local flap with costal cartilage block is one of the most favorable methods in ear elevation which can maintain the adequate projection and make natural looking auriculocephalic sulcus.

Although most available IOL power calculation formulas perform accurately for eyes of average axial length, they have been shown to be inaccurate for eyes that have unusually short and long axial length. To compare the prediction accuracy of new Hoffer Q with SRK-II formula, we reviewed, retrospectively, a series of 225 ECCE with PCL implantation cases, including 106 Hoffer Q group and 119 SRK-II group, each of which was further divided into subgroups based on axial length. The Hoffer Q formula overestimated the refraction and resulted in more myopic shift and was less accurate than SRK-II in all length eyes, except short length eyes. In short length eyes, both formulas had similar mean error and mean absolute error but Hoffer Q formula was more accurate than the SRK-II in +/- 0.5D prediction proportion.

Polymorphic reticulosis(PMR) is a unique clinicopathological entity of unknown etiology, which commonly present as an aggressive, necrotizing lesion of the upper respiratory tract. It is a separate nosologic entity from Wegener's granulomatosis and idiopathic mildine destructive disease. The origin of the cells composing polymorphic reticulosis has been controversial. We reviewed 15 cases of polymorphic reticulosis with respect to clinical and histologic bases, and immunohistochemical studies were done using UCHLI (CD45RO), as a T cell marker, CD-20 as a B cell marker and alpha- I -antichymotrypsin as a histiocytic marker. Almost all cases showed characteristic histologic and immunohistochemical features similar to those of peripheral T cell lymphoma. Thus, this study indidcated that polymorphic reticulosis is a type of malignant lymphoma of T cell lineage.

STUDY DESIGN: This retrospective study was designed to find the causes of adjacent-segment changes and to investigate the correlation between these changes and clinical results in long-term follow-up patients after instrumental lumbar fixation and posterolateral fusion. OBJECTIVE: To quantify how immobilization of a rigid spinal segment fixation effect the pre-existing degenerated adjacent-segment and to observe the adjacent-segment changes, contributing factors of adjacent-segment changes and to investigate the the correlation between clinical results and adjacent-segment changes. SUMMARY OF LITERATURE REVIEW: The reduction in the number of mobile lumbar segments with posterior instrumentation and fusion causes an increased stress in the unfused segment, predisposing them to early degeneration. In addition, the adjacent-segment above the rigid fixation is a particular problem in the previously degenerative spine, which accelerated degeneration at adjacent-segment Many clinical studies reported that stress of the adjacent-segment could develop the significant incidence of spondylolisthesis, spondylolysis and spinal stenosis. MATERIALS AND METHODS: Forty patients were retrospectively reviewed who underwent wide laminectomy and intertransverse fusion with posterior instrumentation. Inclusion in the study required minimum of 5 years of clinical and radiographic follow-up. Nineteen patients were diagnosed as degenerative spondylolisthesis, degenerative scoliosis in 8, pure spinal stenosis in 6 and lytic spondylolisthesis in 7. The most common fused segments were L4-5 in 16. Initial radiographs including plain radiogram, CT and MRI were classified with respect to presence of degeneration adjacent to fused segments. A preoperative spinal instability was diagnosed when any of the following conditions were noted at adjacent above the fusion: 1) >15degrees angulatory instability, 2) >3mm translation, 3) >5degrees lateral angulation, 4) >grade 1 rotational deformity, and postoperative adjacent changes were diagnosed 1) same as preoperative instability criteria, 2) fracture, 3) spinal stenosis, 4) spondylolysis. Clinical results were categorized as poor, fair, good and excellent. RESULTS: Of 40 patients, 16(40%) patients had significant adjacent-segment changes such as instability in six, fracture in aye, spinal stenosis in four and lysis in one. Incidence of adjacent- segment changes was significantly higher in more than 54-years old. Degenerative scoliosis had a higher adjacent-segment chanties and showed statistically significant between preoperative disease and adjacent-segment changes. Nine patients who had a preoperative instability showed significant adjacent-segment changes. Of remained 31 patients, only 7 patients had adjacent-segment changes. There was a statistically significant difference according to preexisting adjacent-segment degeneration. All five patients with grade 3 degeneration developed significant adjacent-segment changes. In overall clinical results, all 7 poor cases had significant adjacent-segment changes. Of them,5 patients should undergo reoperation. CONCLUSION: Inevitable compensatory mechanism occurs at adjacent segment, resulting from stress concentration and alteration in motion kinematics after fusion. The most important factors associated with adjacent-segment changes were age, pre-existing degeneration and preoperative instability. The adjacent-segment changes had a significant correlation with poor clinical results.
