The radiological findings of various cervical spine fractures were analized on the basis of J.Harrisclassification. It appears to be important for the radiologist to be familiar with radiographic findings ofcervical spine fractures, particularly those of unstable fractures which can result in serious medical problems ifimproperly handled in the department of radiology. 68 cases of cervial spine fracures were analized. The resultsare as follows; 1. Stable and unstable fracures were about equal in incedence. 2. Anterior subluxation accountsfor 43.4% of stable fractures, 19% of all fractures. 3. Bilateral interfacetal dislocation accounts for 51.1% ofunstable fractures, 255 of all fractures. 4. Associated fracture were involved in skull, scapula, mandible andfemur. 5. About 80% of the patients is in third through fifth decade.

PURPOSE: To evaluate the incidence, risk factors and prognosis of delirium in elderly patients with intertrochanteric fractures of femur. MATERIALS AND METHODS: 162 patients who underwent operation for intertrochanteric fracture of femur from July 2005 to January 2007 were reviewed retrospectively. Delirium was diagnosed by using Confusion Assessment Method (CAM). Medical records were reviewed for the information of the patients, Gross motor function classification of Palisano et al. was used for the evaluation of ambulatory status. Univariate analysis and multivariate analysis were done to find out the risk factors. RESULTS: 2 cases out of 162 (1.2%) met the criteria of delirium at admission, and 39 cases (24.1%) after surgery. Univariate analysis and multivariate analysis identified age, hematocrit, dementia, the duration of opiate use, and pulmonary complication as risk factors. Hospital stay was longer and postoperative ambulatory status was worse in the patients with delirium. CONCLUSION: Delirium is a frequent complication of intertrochanteric fractures of old age and associated with worse results. Cognitive function as well as physical status should be evaluated before and after surgery. Delirium needs more active prevention and treatment for better results.

Calcific tendinitis is most common seen within the rotator cuff of the shoulder, although it may develop around the hip, wrist, elbow, knee, forefoot, and neck. However, there has been no report in the medical literature regarding calcific tendinitis of the common extensor tendon. We present a case of a 26-year-old woman who had calcific tendinitis of the common extensor tendon. Intraoperatively, partial rupture and calcific deposit at the insertion of the common extensor tendon were seen. We were removed calcific deposit and ruptured tissue of common extensor tendon, and then ruptured common extensor tendon was sutured. The patient showed excellent result two years postoperatively with return to range in a degree of activity levels.

Patellofemoral joint problems refer to a spectrum of conditions affecting the patellofemoral joint, which is the joint between the patella and femur. These conditions can cause pain and instability in the knee and affect an individual’s ability to perform daily activities. Patellofemoral joint problems commonly cause knee pain, particularly among young athletes and physically active individuals. This review article discusses current patellofemoral joint problems, including their epidemiology, pathophysiology, diagnosis, and management.Current Concepts: Patellofemoral joint problems are presented as clinical symptoms of pain and instability. Dividing the diagnostic criteria into anterior knee pain, patella instability, and patellofemoral arthritis is useful. Anterior knee pain is diagnosed after excluding possible causes. Patellar instability is classified into recurrent dislocation, habitual dislocation (extension and flexion types), and permanent dislocation. Moreover, patellar instability can progress to the final stage of patellofemoral arthritis. Thus, patellar instability should be treated according to the Dejour criterion, and patellofemoral arthritis treatment requires artificial joint replacement surgery.Discussion and Conclusion: The pathological mechanism of patellofemoral joint problems still needs to be properly established, and multifactorial causes make it difficult to treat patellofemoral joint problems. Accurate diagnosis is considered an essential factor for successful treatment.

PURPOSE: The authors evaluated the differences between K-wires and Bold screw for fixing the proximal metatarsal chevron osteotomy of moderate and severe hallux valgus. MATERIALS AND METHODS: There were 59 patients (81 feet) who were moderate and severe degree hallux valgus according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity. All patients were followed up at least 6 months. We divided the patients into 2 groups, K-wires fixed group as A, Bold screw fixed group as B. Group A were 42 patients (63 feet) and Group B were 18 patients (19 feet). Among the Group B, 2 feet who were failed to fix the oetotomy site with Bold screw, were fixed with K-wires during operation. We measured the AOFAS score preoperatively, postoperatively and at final follow-up, VAS score at 2 weeks after the operation. Also preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured for each patients. RESULTS: Mean follow up period was 1.34 year (range: 6 months-6.16 years). Mean VAS score of group A was 3.21+/-1.7 and group B 1.76+/-1.0. Preoperative mean AOFAS score of group A was 45.61+/-8.3, group B 44.41+/-8.9, the final mean score of group A was 88.87+/-8.3 and group B 92.47+/-4.4. Preoperative mean HVA was 30.82+/-6.6 degrees in group A and 32.88+/-14.5 degrees in group B, the final mean angle of group A was 14.89+/-8.3 degrees and group B 17+/-4.4 degrees. The preoperative mean IMA of group A was 13.69+/-3.6 degrees and group B 12.35+/-5.2, the final mean angle of group A was 9.26+/-3.6 degrees and group B 12.35+/-5.8 degrees. CONCLUSION: There were no statistical differences in radiologic and clinical results (p>0.05) but, group B exceeded group A in VAS score (p=0.0007) and had no statistical significance in terms of reduction angle loss (p=0.06). Early returning to normal life activity may be possible for patients using Bold screws.

In order to investigate the anti-proliferative effect of 3-hydroxy-3-methylglutaryl coenzyme. A reductase inhibitor, we evaluated the effects of lovastatin on DNA replication and the proliferation of rat mesangial and aortic smooth muscle cells, both of which were mesenchymal origin cells. Proliferations were determined by measuring [3H]thymidine uptake, and counting the number of cells. Growth-arrested mesangial and aortic smooth muscle cells were exposed to platelet-derived growth factor (PDGF), endothelin (ET) and angiotensin II (Ang II) to stimulate mitogenesis. All agents exhibited dose-dependent stimulation of [3H] thymidine uptake. PDGF was more potent than the others. Ang II increased [3H] thymidine uptake without demonstrable mitogenic activity. Lovastatin inhibited PDGF (10 ng/ml in mesangial cell, 25 ng/ml in smooth muscle cell)-, ET (10(-7)M)- and Ang II (10(-7)M)-induced [3H] thymidine uptake significantly in a dose-dependent manner in both cells. The increase of cell number in response to PDGF and ET treatment were also inhibited at 10 microM of lovastatin. The inhibitory effect of lovastatin was largely overcome in the presence of exogenous mevalonate at 200 microM, with 75.5% restoration from lovastatin-induced inhibition on PDGF-induced [3H] thymidine uptake in mesangial cells (77.8% in aortic smooth muscle cells). However, the addition of cholesterol did not prevent inhibition by lovastatin. In conclusion, lovastatin had an inhibitory effect on mesangial and aortic smooth muscle cell proliferation, and mevalonate was essential for DNA replication in both types of cells. Lovastatin may reduce glomerular and atherosclerotic injury through an anti-proliferative effect on mesangial and vascular smooth muscle cells, in addition to lowering circulating lipids.

BACKGROUND: Peritoneal fibrosis is one of the major causes of technical failure in patients on peritoneal dialysis. Epithelial-to-mesenchymal transition (EMT) of the peritoneum is an early and reversible mechanism of peritoneal fibrosis. Human peritoneal mesothelial cells (HPMCs) have their own renin-angiotensin-aldosterone system (RAAS), however, it has not been investigated whether aldosterone, an end-product of the RAAS, induces EMT in HPMCs, and which mechanisms are responsible for aldosterone-induced EMT. METHODS: EMT of HPMCs was evaluated by comparing the expression of epithelial cell marker, E-cadherin, and mesenchymal cell marker, alpha-smooth muscle actin after stimulation with aldosterone (1-100nM) or spironolactone. Activation of extracellular signal-regulated kinase (ERK)1/2 and p38 mitogen-activated protein kinase (MAPK) and generation of reactive oxygen species (ROS) were assessed by western blotting and 2',7'-dichlorofluororescein diacetate staining, respectively. The effects of MAPK inhibitors or antioxidants (N-acetyl cysteine, apocynin, and rotenone) on aldosterone-induced EMT were evaluated. RESULTS: Aldosterone induced EMT in cultured HPMCs, and spironolactone blocked aldosterone-induced EMT. Aldosterone induced activation of both ERK1/2 and p38 MAPK from 1 hour. Either PD98059, an inhibitor of ERK1/2, or SB20358, an inhibitor of p38 MAPK, attenuated aldosterone-induced EMT. Aldosterone induced ROS in HPMCs from 5 minutes, and antioxidant treatment ameliorated aldosterone-induced EMT. N-acetyl cysteine and apocynin alleviated activation of ERK and p38 MAPK. CONCLUSION: Aldosterone induced EMT in HPMCs by acting through the mineralocorticoid receptor. Aldosterone-induced generation of ROS followed by activation of ERK, and p38 MAPK served as one of the mechanisms of aldosterone-induced EMT of HPMCs.

STUDY DESIGN: This is a prospective radiographic study. OBJECTIVES: We wanted to describe and quantify the common variations in the sagittal lumbar spine. SUMMARY OF THE LITERATURE REVIEW: No previous study of the spinopelvic parameters with a large cohort of asymptomatic young men was performed on subjects with the same ethnic background. MATERIALS AND METHODS: 166 young males without disease, trauma or a history of operation on the spine or lower extremities were included. The sagittal standing radiographs of the whole spine on 36 inch film were taken. The distances from the plumb line of C7, T12, the lumbar apex and the bicoxofemoral head to the posterosuperior corner of the sacrum were measured. Thoracic kyphosis, thoracolumbar kyphosis, lumbar lordosis, the segmental vertebral slopes, the sacral slope and the pelvic incidence were measured. Groups 1 and 2 were classified by having a sacral slope less than 35degrees (group 1: apex below L4, group 2: above L4). Group 3 had a sacral slope between 35degrees and 45degrees, and group 4 had a sacral slope greater than 45degrees. RESULTS: The average age was 21.8 years (range: 19~26 years). Group 1 contained 37 cases, group 2 had 44, group 3 had 62 and group 4 had 23. Thoracolumbar kyphosis was significantly increased in group 1 and lumbar lordosis and pelvic incidence were increased in groups 3 and 4. Thoracic kyphosis and the vertebral slope of T12 did not demonstrate any difference between the groups. CONCLUSION: The sagittal spinopelvic parameters showed significant changes according to the morphology of the lower lumbar spine. Understanding the patterns of variation in the spinopelvic parameters may help surgeons to plan treatment for various spinal lesions.

A 67-year-old male patient came to the hospital due to lung cancer and mediastinal cystic mass which was suspected to be esophageal duplication cyst. Video-assisted thoracoscopic surgery (VATS) was performed and intra-operative finding suggested it as a cystic mass along the thoracic duct. Thoracic duct was ligated and the cyst was completely resected. A 48-year-old female patient visited the hospital for dysphagia. Mediastinal cystic mass was suspected to be an esophageal duplication cyst. Intraoperative finding suggest a thoracic duct lymphangioma. After thoracic duct ligation, the mass was completely resected with VATS. Postoperative chylothorax did not develop in both cases.
