Two cases of spontaneous kidney rupture with literatural review was presented at first in Korea. 1) 56 years male patient and 25 years male patient admitted to our department of Urology through Emergency Room after onset of 2 and 1 day. after treatment at local clinic. 2) Chief complaints were one side flank pain which was followed by total gross hematuria. 3) Preoperative diagnoses were kidney rupture due to necrotic pelvic tumor in 56 years male and hypernephroma in 25 years male patient. 4) Operation was procedured at 8 days and 4 days after admission respectively. 5) The operative procedure were nephrectomy in both cases. 6) The pathological diagnoses were pelvis rupture due to renal stone and parenchymal rupture due to renal infarction in each case.

Cancer may be a disease of genes, arising from genetic damage of diverse sorts-recessive and dominant mutations, large rearrangement of DNA and gene translocation on chromosomes, all leading to distorisions of either the expression or biochemical function of genes. The search for these genetic damage in neoplastic cells now is the most important in cancer research. It has been found that the cancer relevant genes were located on the specific regions of chromosomes. To determine whether epidermal growth factor receptor(EGFR), P53 and bcr genes located in chromosomes 7, 17 and 22 are altered, we examined 12 neuroepithelial tumor with Southern blot analysis(five low grade astrocytoma, two high grade astrocytoma, two medulloblastoma, on oligodendroglioma, one ependymoma, one choroid plexus papilloma). The loss of heterozygosity(LOH) of EGFR gene was detected in two cases of medulloblastoma. The rearrangement of EGFR gene was detected in a case of ependymoma. The LOH of P53 gene was found in a case of choroid plexus papilloma and low grade astrocytoma. The rearrangement of P53 gene was founs id a case of oligodendroglioma. The LOH of bcr gene was observed in two cases of medulloblastoma and low grade astrocytoma. The rearrangement of bcr gene was observed in two cases of high grade astrocytoma. These results suggested that tumorigenesis and tumor development in the neuroepithelial tumor may invlove specific gene changes in chromosomes 7, 17 and 22.

The clinical and pathological features were analyzed for 11 cases with intracranial ependymoma treated surgically at the Keimyung University Dongsan Medical Center during the years 1987 to 1992. Tumor histology was reviewed individually and grouped into three categories(Categories I to III) according to the pathologic grade used by Nazar, et al. There were 2 cases(18%) with category I histology, 5(45%) with category II histology, and 4(36%) with category III histology. The high recurrent rate, short recurrent interval, high rate of cerebrospinal fluid seeding and poor outcome were noted in patients with category III histology. The authors also investigated the recurrent interval according to the degree of tumor resection. The mean recurrent interval after surgery was 12 months in cases of subtotal resection and 33 months in a case of total resection. Tumors resected subtotally showed response to radiation and chemotherapy. In conclusion, the pathologic grade and the degree of tumor resection were regarded as important prognostic factors after surgery. Aggressive surgery with chemotherapy or radiotherapy were required in the management of intracranial ependymoma.

We report a case of myxoid sarcoma in the left atrium, which was diagnosed as benign myxoma on preoperative echocardiography. At operation, semisolid mobile masses were found that attached with broad stalk to the posterior left atrial wall and that invaded into the left pulmonary vein and the anterior mitral leaflet. The patient underwent excision of left atrial tumor masses, mitral valve replacement, and left pneumonectomy. The histological diagnosis was undifferentiated cardiac myxoid sarcoma. Although echocardiography lead to the choice of diagnostic test of intra-atrial tumor, magnetic resonance imaging, computed tomography, and intraoperative transesophageal echocardiography may be needed for differential diagnosis, with indeterminate malignant findings on preoperative transthoracic echocardiography. Anesthesiologists are often confronted with cases that are unusual, therefore preoperative understanding of the cases are important for safe anesthetic management.

Frontotemporal dementia is a common cause of dementia and distinguished from Alzheimer's disease. Because its clinical symptoms are characterized by slow progressive social breakdown and change of personality before cognitive impairments become prominent, it may be diagosed as other psychiatric disease. We have presented three cases of frontotemporal dementia. They had typical clinical histories and symptoms which deserve to be considered frontotemporal dementia. They showed appropriate findings of frontotemporal dementia in the neuropsychological tests and brain imaging study with brain magnetic resonance imaging and 18F-FDG positron emission tomography. Their clinical histories and findings are thought to be helpful for clinician to give attention to and diagnose frontotemporal dementia.

A blastoma is a type of cancer, which is common in children; it is caused by malignancies derived from in the precursor cells, often called blasts. Examples are nephroblastomas, retinoblastomas, pleuropulmonary blastomas, and pancreatoblastomas. Pancreatoblastomas are extremely rarely in adults. It is difficult preoperatively to distinguish this tumor from other pancreatic tumors including solid and papillary epithelial neoplasm of the pancreas (SPEN), acinar cell carcinoma, islet cell tumor, and ductal adenocarcinoma with cystic degeneration. To our knowledge, this case may be the second report of a pancreatoblastoma occurring in an adult in Korea. We report a case of a pancreatoblastoma that was confirmed by pathology, despite the radiologic finding that assumed it was a SPEN.

Interstitial cells of Cajal (ICC) are the pacemakers in gastrointestinal slow wave, and also transduce signal inputs from the enteric nervous system to smooth muscle. The abnormal motility corresponded to a lack or decreasing of ICC and a disruption of electrical slow waves. So we developed partial obstruction model in murine small intestine and investigated changes in the ICC networks and electrical activity in the obstructed bowel using c-kit immunohistochemistry and intracelluar electrophysiological techniques. Two weeks following the onset of a partial obstruction, the small intestine increased in diameter and muscular hypertrophy was developed oral to the obstruction site. ICC were absent or only weak at 1 ~25 mm oral to the occlusion site, and this disruption was accompanied by the loss of electrical slow wave. ICC networks and slow waves were normal appearance aboral to the clip. In conclusion, The present results showed that partial intestinal obstruction induced the loss of ICC networks and slow waves. These result will provide a valuable aid for understanding pathogenesis of intestinal motility disorder, and this model may be an important tool for evaluating genetic or molecular factor for the therapeutic opportunities of motility disorder in human.
