BACKGROUND: Osteoarthritis(OA) has become one of the most important medical problem among the old age because it causes severe functional disability, but, up to date, the therapeutic methods for OA have not been so satisfactory to the patients with OA. Authors have investigated the effectiveness of intramuscular stimulation(IMS) therapy as an substitutive therapy for the relief of pain and dysfunction in patients with OA of the knee. METHODS: Eighteen patients who had visited the department of family medicine, Korea university anam hospital, with symptomatic OA of the knee during the period from March 1 to May 31. 2001 were included in this study and treated with IMS therapy on the quadriceps and hamstring muscles four times during two weeks. Patients self-scored Korean Western Ontario and McMaster universities Osteoarthritis Index (KWOMAC) at baseline and after the last therapy. The result was analysed by paired t-test and ANOVA. RESULT: Patients improved on KWOMAC scales for pain, stiffness, function and total scores after IMS therapy(p<0.05). The demographic characteristics such as body mass index (BML), duration of disease, affected site, radiologic finding did not have influence on the result of this study. No adverse effects of IMS therapy were reported. CONCLUSION: In this study, the improvement of pain, stiffness, and function of knee joint after treatment was reported. This study suggest that IMS is an effective and safe substitutive therapy for patients with OA of Knee.

OBJECTIVE: Proximal junctional kyphosis (PJK) is radiologic finding, and is defined as kyphosis of >10° at the proximal end of a construct. The aim of this study is to identify factors associated with PJK after segmental spinal instrumented fusion in adults with spinal deformity with a minimum follow-up of 2 years. METHODS: A total of 49 cases of adult spinal deformity treated by segmental spinal instrumented fusion at two university hospitals from 2004 to 2011 were enrolled in this study. All enrolled cases included at least 4 or more levels from L5 or the sacral level. The patients were divided into two groups based on the presence of PJK during follow-up, and these two groups were compared to identify factors related to PJK. RESULTS: PJK was observed in 16 of the 49 cases. Age, sex and mean follow-up duration were not statistically different between two groups. However, mean bone marrow density (BMD) and mean back muscle volume at the T10 to L2 level was significantly lower in the PJK group. Preoperatively, the distance between the C7 plumb line and uppermost instrumented vertebra (UIV) were no different in the two groups, but at final follow-up a significant intergroup difference was observed. Interestingly, spinal instrumentation factors, such as, receipt of a revision operation, the use of a cross-link, and screw fracture were no different in the two groups at final follow-up. CONCLUSION: Preoperative BMD, sagittal imbalance at UIV, and thoracolumbar muscle volume were found to be strongly associated with the presence of PJK.

Total cholesterol and triglyceride were measured in sera of 40 cases of hypertension, 22 cases of myocardial infarction, 14 cases of cerebral thrombosis, 18 cases of subarachnoidal hemorrhage and 30 cases of normal control in Chungnam national University Hospital from October 1980 to September 1981, and the results are as follows; 1) The mean serum total cholesterol and triglyceride levels in normal control group are 153.57+/-40.60mg% and 150.82+/-51.76mg%. 2) The age incidence of these diseases were highest in 6th decade. 3) Serum cholesterol levels of myocardial infarction, hypertension, cerebral thrombosis and subarachinoidal hemorrhage group were higher than that of normal control group. 4) Serum triglyceride levels of acute myocardial infarction and hypertension were significantly higher than that of normal control group, but there is only slightly increases in cerebral thrombosis and subarachinoidal hemorrhage. 5) In general, serum lipid levels are higher in cardiovascular diseases(hypertension and myocardial infarction) than cerebrovascular diseases(cerebral thrombosis and subarachnoidal hemorrhage). 6) Serum Cholesterol and triglyceride levels decreased by administration of pancreatic mucopolysacharide for 1 or 2 months. In conclusion, it seems that high serum cholesterol and triglyceride level may play and important risk factor in development of hypertension and myocardial infarction.

Generally, the left kidney from a living donor is more commonly preferred but the right kidney is occasionally donated because of multiple left renal arteries or repeated transplantation. The right donor nephrectomy is usually more difficult compared to the left because the right renal vein is often multiple and short, which complicates dissection of the vascular pedicle. From Jan. 1989 to Sep. 1992, 112 consecutive cases of right donor nephrectomies out of a total of 771 cases were retrospectively reviewed with the preoperative renal angiography and the intraoperative assessment of the right renal vascular pedicle. The indications for right donor nephrectomy include 1) multiple or proximal bifurcating renal arteries of the left kidney (89.3%), 2) repeated transplantation in the recipient (9%). In 26.8% of the cases, there were more than two right renal veins. In the right donor nephrectomy, it is often necessary to perform vena cava cuff resection because of short and frequently occurring multiple right renal veins. For the dissection of the inferior vena cava (IVC), the aberrantly occurring right gonadal vein, the adrenal vein draining above the junction of the renal vein and IVC, and the lumbar vein below the junction should always be looked for and must be ligated if any are found.

From January 1986 to December 1990, preliminary percutaneous nephrostomy (PCN) was performed on 16 children for hydronephrosis. Infection was the most frequent presenting feature. This procedure was useful for providing drainage of pyonephrotic kidneys, for accessing recovery of renal function after relief of obstruction, and for preserving or regaining renal function in patients who were not fit for major surgery. Complications were uncommon and usually minor. Our experience has encouraged us to accept this procedure, both diagnostically and therapeutically. And we believe that it is safe, easily performed and effective and has become a valuable non-surgical alternative that should be favorable to manage children, especially infants, with urinary tract obstruction.

The previous reports have indicated that both the DMSA scan and the DTPA scan were significantly related with the relative renal function ( RRF) and there was a close relationship between the DMSA scan and the DTPA scan in the evaluation of the RRF We reviewed our experience with 24 cases, in which the DMSA scan and the DTPA scan were performed within 2 weeks from January 1987 to April 1991. The DMSA scan was more reliable than the DTPA scan and the difference of the RRF between right and left side by the DMSA scan was more apparent than that by the DTPA scan. However, in infants, both scans showed the reversed results. Our study suggests that DMSA scan is more reliable than the DTPA scan in the evaluation of the RRF, but both renal scans are inappropriate in infants, especially under the age of 1 months.

BACKGROUND: Osteoarthritis(OA) of the knee represents a common chronic disease, especially in the elderly, leading to functional impairment and disability. And OA patients have depressive symptoms frequently. Several factors contribute to the level of depressive symptoms. Authors tried to assess these factors and show effect of these factors to depressive symptoms. Through this study in the future physicians must consider psychiatric problems besides the pain itself in the treatment of OA patients. METHODS: Subjects included in this study were 64 knee joint OA patients. We obtained depressive symptoms from the CES-D(The Korean version of the Center for Epidemiological Studies-Depression Scale), level of pain, stiffness, functional disability from KWOMAC(WOMAC Korean Version 2, The Korean version of Western Ontario and Macmaster Osteoarthritis Index Score) and other factors able to contribute to depressive symptoms. RESULT: We divided the patients into two groups using CES-D cut-off score of 21. Each group consists of 46(CES-D<21) and 18(CES-D> or =21) patients. Frequency of sleep disturbance and pain consistency and level of pain, stiffness and functional disability were different significantly between two groups(p<0.0l). Through the correlation analysis level of pain, stiffness and functional disability were associated with CES-D score significantly(p<0.0l). And through the stepwise multiple regression analysis we demonstratred that the CES-D score influenced by level of functional disability, BMI, disease duration and, pain but only level of functional disability and BML were statistically significant(p<0.0l). Level of functional disability explained 46% of CES-D score(partial R2=0.46) so influenced on depressive symptoms most effectively. CONCLUSION: This study suggested that functional disability was most important factors to explain depressive symptoms of knee joint OA patients.

Although they usually originate from peripheral problems, foot drop is caused by lesions affecting the neural pathway related to dorsiflexor muscles, whether of central or peripheral origin. We present a patient with sudden isolated foot drop caused by a small infarct in the primary motor cortex mimicking a peripheral origin. This report indicates that patients presenting isolated foot drop should be managed carefully and the possibility of both central and peripheral causes should be considered. To our knowledge, this is the first report of sudden isolated foot drop caused by a cortical infarction mimicking lumbar radiculopathy.

Common radiographic appearances of ossifying fibroma (OF) are well demarcated margin, radiolucent or mixed lesion. Lesions for the radiographic differential diagnosis with OF include fibrous dysplasia, focal cemento-osseous dysplasia. Other confusing lesions might be the mixed lesions such as calcifying odontogenic cyst, adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, and benign cementoblastoma. We reported three cases of OF in posterior mandible. These cases showed a little distinguished radiographic features of OF and diagnosed from a combination of clinical, radiographic, and histopathologic information. We need to further refine radiographic and histopathological features of OF and other confusing lesions with literatures review because some cases of these lesions are not easily differentiated radiographically and histopathologically.
