PURPOSE: To evaluate the MR image in the differentiation of benign and malignant lesion in compression of the vertebral body. MATERIALS AND METHODS: MR images of 47 benign(acute traumatic within one month:19, chronic traumatic longer than one month or nontraumatic:28) and 21 metastatic compression fractures were respectively reviewed in terms of margin of lesions, signal intensity, paraspinal mass formation, soft tissue change, and involvement of posterior element of vertebra. MR images of TI-(T1WI) and T2*-weighted gradient echo (GE T2WI) sequences were obtained on 0.5T unit in sagittal and axial orientation with 5mm section thickness. RESULTS: The margin of benign compression fracture was usually indistinct (acute fracture:90% (17/19), chronic fracture:68% (19/28)), whereas it was sharply delineated in metastatic compression fracture (92%, (12/13) (p<0.001). Paraspinal mass was seen in both acute traumatic and metastatic compression fractures (acute fracture :26% (5/19), metastatic fracture: 52% (11/21). Soft tissue change was seen only in acute cornpression fractures (58%, 11/19). Involvement of posterior element of vertebra was noted in metastatic fracture (71%, 15/21), acute fracture (32%, 6/19) and chronic fracture (7%, 2/28) CONCLUSION: On MR imaging, involvement of entire portion of a given vertebral body, sharp margin between normal and abnormal areas in partially involved cases, paraspinal mass formation, and posterior element involvement are more frequently seen in metastatic compression fractures, which are considered to be useful in differentiation between benign and malignant causes of compression fracture.

OBJECTIVE: The aim of this study is to evaluate the role of tumor suppressor genes, p53 and Rb gene, as well as apoptosis in the carcinogenesis of ovarian epithelial tumors. And the value of these factors as prognostic markers to tell the transformation of borderline tumors to overt carcinomas is also studied. METHOD: Thirty cases of ovarian epithelial benign and borderline tumors and invasive carcinoma were used and the expression of the p53 protein and Rb gene protein were evaluated by immunohistochemical method. The apoptosis was evaluated by TUNNEL method. RESULTS: Positive rate of p53 expression in benign, borderline and invasive tumors were 0, 28, and 94 %, respectively. And also, p53 was highly expressed in chemoresistant cases (2/3), in residual tumor (4/5) and in recurred cancer (2/2). Rb protein was partly lost in the borderline tumors, but the rate of Rb protein loss in both borderline tumors and invasive carcinomas were similar. Apoptosis were more active in overt carcinomas than in borderline and benign tumors. In borderline tumors, p53 protein was expressed as 28.6% positivity, and apoptosis was expressed as 28.6% negativity, which showed indirectly that there was apoptosis induction effect of p53. In ten cases of invasive carcinomas showing highly expressed p53, apoptosis revealed all positive reaction except 2 cases, and Rb protein revealed variously. This result supported the apoptosis imduction effect of p53, but it was difficult to find the association of expression degree between the two tumor supressor genes CONCLUSION: In conclusion, the values of p53 is a discriminating factor of malignancy from benign and the expression of p53 is related with clinical aggressivity such as recurrence and residual cancers. Apoptosis are more active in overt carcinoma than in benign & borderline tumor, and in borderline tumor the expression of p53 is related to apoptosis induction which results to carcinomatous change.

In the present study, we investigated the differences in the levels of expression of virulence factors between blood isolates of Candida albicans and commensal strain isolated from the oral cavities of health volunteers, and correlations between virulence factors. Blood isolates of 33 and commenal isolates of 71 were characterized by putative virulence factors such as proteinase production (PROT), an ability to adhere to epithelial cells (ADH), cell surface hydrophobicity (CSH), phospholipase production (PLASE), and hyphal transition (GERM). In PROT, ADH, CSH, and PLASE, the means of expression of blood isolates were higher compared with those of commensal isolates, however statistical significance was only shown in CSH (p=0.036). On the contrary, mean expression of GERM of blood isolates was lower than that of commensal isolates. Of relationships between virulence factors, although a negative correlation of PROT with CSH was obtained, the correlation was relatively low (r=-0.316, p=0.001). These results suggest that higher expression of CSH is a more distinguishing character in virulent blood isolates of C. albicans and that the expression of virulence factors are independent.

A wide variety of cancers metastasize to the ovaries. In a majority of instances the primary site is the gastrointestinal tract, breast, or other gynecologic organs. The best known tumor of this type is signet-ring cell adenocarcinoma. The gallbladder and bile duct are rare sources of these metastases. The authors have had an experience of a case that was presented of Krukenberg tumor metastatic from the gallbladder and report the case with brief review of literature.

Cerebral palsy is a non-progressive cerebral sensori-motor defect, acquired either prenatally or in an early life and evolves over the first few years. Until recently many people believed that asphyxia at birth was a major cause of cerebral palsy and that the prevention of asphyxia at birth by improving perinatal care would reduce the number of cerebral palsy children. However the incidence of cerebral palsy in children has remained steady or ever risen slightly. The real cause of cerebral palsy is still unbaron to us. This analysis was undertaken to determine the clinical features of cerebral palsy in Korea by the retrospective study of 98 children. Over a half of infants with cerebral palsy (64.2%) was recognized by parents before 1 year of corrected age, and their chief complaints were delayed developments or equinus foot deformities. The most common type of cerebral palsy was spastic type (64.2%) which was followed by athetoid (10.5%), ataxia and hypotonia types (4.2% each). The mixed type was 19.4% Among 98 cerebral palsies, the preterm infants were 42.9% and the infants with low birth weight were 41.4%. The cerebral palsies with low birth weight and preterm infants were more likely to have spastic diplegia. The most frequent abnormal primitive reflex was absent protective extension(78.3%). No significant associations of the type of cerebral palsy with primitive reflexes were found. An increased risk of cerebral palsy with increased maternal age was not observed in this study. Of 55 MRI findings, no abnormalities were seen in 27.2%, periventricular leukomalacias in 34.5%, brain atrophies in 21.8%, cerebral infarcts in 10.9%, intracerebral hemorrhage in 3.6%, and delayed myelinations in 1.8%. The periventricular leukomalacias were associated with the preterm infants in 63.2%.

Primary epiploic appendagitis (PEA) is an uncommon cause of acute abdominal pain that occurs either from appendageal torsion or spontaneous thrombosis of an appendageal vein. It is a benign condition that may present with peritoneal findings. Thus, it is rarely considered in the differential diagnosis of intra-abdominal disease. Until recently, an accurate diagnosis could not be made preoperatively. With the aid of contemporary imaging modalities, however, the diagnosis of PEA need no longer hinge on the pathologic specimen, but may be established by the emergency physician. Common findings include left lower quadrant pain and guarding. Nonmigratory symptoms should also prompt the clinician to consider a CT scan in patients with similar signs and symptoms. Knowledge of this uncommonly diagnosed entity and its usual benign course may allow the emergency physician to order the appropriate studies to help avoid unnecessary surgical treatment. The anatomy, the clinical presentation, the radiologic evaluation, and the emergency management of epiploic appendagitis are reviewed with the literature.

Occurrence of primary cardiac tumors is rare in all age groups; occurrence is observed in 0.05% of routine postmortem examinations. A 15-year-old Korean female transported by 119 rescue presented with common clinical findings for acute stroke. Brain imaging included computed tomography; magnetic resonance imaging was performed in the emergency department. Findings on brain imaging were compatible with acute cerebral infarction of the territory of the right middle cerebral artery. The patient was treated with reperfusion therapy with IV tissue plasminogen activator and cerebral artery stenting. Echocardiography was performed in the emergency department in order to determine the cause of acute cerebral infarction. We experienced a case of pediatric cardiac myxoma presenting as an acute stroke in the emergency department, which was confirmed by imaging study and biopsy; therefore, we report on it here along with a review of the literature.
