PURPOSE: The clusterin expression has been associated with tumorigenesis of various malignancies, including tumors of the prostate, colon and breast. Furthermore, the expression of clusterin is modulated by many factors that are believed to regulate tumor growth and apoptosis. We studied the clusterin expression in transitional cell carcinoma (TCC) of the bladder and we investigated its correlation with apoptosis. MATERIALS AND METHODS: Eighty five bladder tumor specimens from radical cystectomy or transurethral resection were subjected to immunohistochemical clusterin staining with Ig G clusterin Ab. We examined the immunohistochemical localization of clusterin, and this was followed by TUNEL staining to detect the apoptotic cells. After double-staining with Hoechst 33258, we detected the apoptotic cells under a fluorescence microscope and we calculated the apoptotic index. RESULTS: Invasive TCC showed a stronger positive expression of clusterin as compared with superficial TCC, but the positivity of the clusterin expression was not in proportion to the tumor grade. The apoptotic indices of cancer were 0.52+/-0.28%, 0.30+/-0.16% and 0.17+/-0.11% in Grade I, Grade II and Grade III superficial TCC, respectively, and it was 0.23+/-0.13% in Grade III invasive TCC. Apoptotic cells were not detected in the cancer cells stained with clusterin. Conversely, clusterin was not expressed in the cells showing apoptosis. CONCLUSIONS: These results suggest that clusterin could be used as a marker to provide prognostic information for the TCC patients. The apoptotic index revealed that apoptosis and the clusterin expression have correlation with transitional cell cancer. Further study will be needed to clarify the role of clusterin as a therapeutic target for cancer treatment.

OBJECTIVE: Angiogenesis, the formation of blood vessels by sprouting from pre-existing ones, is essential for the growth of solid tumors beyond 2-3mm in diameter and for tumor metastasis. Vascular endothelial growth factor (VEGF), is known as vascular permeability factor(VPF) and mediates vascularization and tumor-induced angiogenesis. This study examined the potential of growth, invasion, and metastasis of uterine cervical carcinomas associated with neovascularization. METHODS: From January 1996 to December 1999, at the Department of Obstetrics and Gynecology, Kyung-Hee University Hospital, 37 uterine cervical carcinomas and 7 normal cervical tissues were obtained and the samples were immediately frozen and stored at -70 degrees C. Immunohistochemical staining for VEGF was carried out to study VEGF localization, and the levels of VEGF subtype mRNAs were determined by quantitative RT-PCR in specimens. The relation between VEGF subtypes expression of cervical cancers was analysed. RESULTS: The positive staining for VEGF is seen dominantly in the cytoplasm of the cancer cells, and faintly in interstitial cells. The intensity of staining was stronger in squamous carcinomas than in adenocrcinomas, but there was no significant difference (p>0.05). Quantitative RT-PCR analysis demonstrated significantly increased VEGF121/VEGF165 mRNA expression levels (>0.56 / >0.72) in 21 (56.8%) and 15 (40.5%) of 37 cervical carcinomas comparing to control groups (mean: 0.28 / 0.36). There was no obvious relationship between VEGF121/VEGF165 mRNA expression levels and the clinical parameters examined including age, pathology, differentiation, tumor size, lymphovascular space invasion, LN involvement and invasion depth except clinical stage (p<0.05). CONCLUSIONS: The overexpression of VEGF mRNA may be an important contributing factor in cervical carcinomas. There is no significant differenece of VEGF mRNAs levels according to clinical parameters, so it seems that the expression of VEGF is involved in the promotion of angiogenesis on cervical cancer and plays an important role in early invasion.

PURPOSE: To determine the activity and toxicities of PEF (Cisplatin, Etoposide, 5-Fluorouracil) chemotherapy for stomach cancer. MATERIALS AND METHODS: Patients with previously untreated metastatic stomach cancer were treated with PEF regimen which consisted of cisplatin (20 mg/m2 i.v. days 1~5), etoposide (100 mg/m2 i.v. days 1, 3, 5), and 5-fluorouracil (5-FU)(800 mg/m2 i.v. infusion for 12 hours days 1~5). Chemotherapy was repeated every 3 weeks until disease progressed or toxicities were intolerable. RESULTS: Between May 1989 and July 1990, 40 patients were enrolled in this protocol. Twelve patients were lost to follow up after one cycle of chemotherapy and inevaluable. After 2~8 cycles (median 3) of chemotherapy, 20 out of 28 evaluable patients showed objective responses without any complete response, making the response rate 71% (95% confidence interval: 54~89%). The responses lasted from 4+ to 39 weeks (median: 38 weeks). The overall survival of total evaluable patients was 4+ ~50+ weeks (median 38 weeks). Among total 109 cycles of chemotherapy, cycles were delayed or doses were reduced in 48 cycles (44%) because of leukopenia (in 61 cycles: 56%) and/or thrombocytopenia (in 14 cycles: 13%). However, there was no treatment-related death. Nausea/vomiting and alopecia were experienced in most of patients. The stomatitis was experienced in 7 patients (25%) but completely reversible. In contrast, the peripheral neuropathy which developed in 4 patients (14%) after 5 cycles of chemotherapy was not reversible. CONCLUSION: The PEF regimen was active and tolerable in stomach cancer.

Mixed mullerian tumors are uncommon tumor and highly malignant containing epithelial and mesenchymal component. Most of these tumors arise spontaneously in the sixth to eight decades of life, but a certain proportion are known to occur in women who have received pelvic irradiation from five to 30 years before for benign or malignant disease. This apparent association has led to the belief that pelvic irradiation somewhat increase the neoplastic potential of the uterine corpus, although the precise role of irradiation in the genesis of uterine neoplasia remain uncertain. We experienced one case of malignant mixed mullerian tumor of uterus developed after pelvic irradiation. So we report the case with a brief review of literature.

Hemimegalencephaly and tuberous sclerosis complex are distinct and rare conditions which are characterized by malformations of cortical developments. Hemimegalencephaly is a cerebral malformation of unknown pathophysiology characterized by asymmetry of the hemispheres and cortical dysplasia. Tuberous sclerosis complex(TSC) is an autosomal dominant neurocutaneous disorder characterized by the formation of hamartomatous lesion in multiple organ systems. While they are currently thought to be unrelated, there are similar cases in the literature and it is conceivable that an abnormality in early cortical development could lead to both conditions in an individual. We report here a first Korean case of unusual association of hemimegalencephaly and tuberous sclerosis complex with mutation in the TSC2 gene, who presented initially frequent partial seizures and infantile spasms.

OBJECTIVES: Electroconvulsive therapy (ECT) is the important treatment method which has a good effect on refractory depression, schizophrenia at acute stage, patients with suicidal ideation. Although ECT results in better effects and less adverse effects in acute stage of illnesses as compared with pharmacotherapy, clinical implications are decreasing. Thus, authors surveyed a view of Korean psychiatrists about ECT to find whether there are prejudices and/or misconceptions for ECT. METHODS: Authors made survey questionaire for the attitudes of ECT, based on the APA task force 14, a clinical study in Korea, Hermann et al's report, and questioned Korean psychiatrists on their opinions for ECT through the internet E-mail, who are the members of Korean Neuropsychiatric Association (KNPA) serving in hospitals with psychiatric inpatient units. RESULTS: 122 psychiatrists answered to survey questionnaire. 89.4% have positive attitude about ECT. They thought that ECT has relatively safe and potent therapeutic effects, and less adverse effects. The rate of psychiatrists who have been no experience to perform ECT was 13.9% (n=16). Interestingly all of them had been trained serve in university hospitals now. The rate of psychiatrists who had experienced practicing ECT past but, not experienced within 2 years recently was 48.7% (n=56). While psychiatrists who have been no experience of ECT were more worried about adverse effects, doctors who experienced practicing ECT thought preferably the aspect of safety and potent effects of ECT. Psychiatrists who prefer psychotherapy were more likely to concern about adverse effect of ECT, but there were no differences in other aspects when compared with others. Most psychiatrists participated in this survey had positive attitudes about application of ECT to geriatric patients, but negative at child&adolescent patients. CONCLUSION: Authors recognized that many Korean psychiatrists agreed with performing ECT, and expected good results, but in reality, it is difficult to expect for them to perform ECT. Several factors may be associated for that: the changes in trend of psychiatric treatment, production of novel psychotropic drugs, researches trends which pharmacotherapy is prevailing in the fields of psychiatry, and problems of education, that is, lack of standard educational curriculums and systemic training course at residency for ECT.

OBJECTIVES: Patients with poor insight are commonly observed among schizophrenics and they show poor drug compliance and prognosis. This study aimed at examining the characteristics of psychopathology in patients with schizophrenia who have no insight. Understanding the features of inner psychopathology in schizophrenic patients with poor insight, we assumed, could lead to insight-promoting clues. METHODS: The subjects consisted of 69 patients with schizophrenia diagnosed by DSM-IV criteria. For identifying insight level in the patients, Scale to Assess Unawareness of Mental Disorder(SUMD) was applied. After subjects were divided into two groups depending upon insight level, psychopathological differences were evaluated by Kyung Hee-Frankfruter Beschwerde Fragebogen(K-FBF), which was known as one of the subjective psychological tests for the schizophrenics. RESULTS: There was no significant differences in demographic variables, duration of illness, and dose of medication between two groups. However, significantly high rate of involuntary admission and tendency of high frequency of admission were revealed in schizophrenic patients with poor insight. And, also poor insight group showed significantly high scores in the factors of sensorimotor disorder(subscales of psychomotor disorder, perceptual disorder and blocking symptoms included) and in language-cognitive disorder factor(subscales of language disorder and cognitive floating included) compared with patients who have insight. CONCLUSION: We was assumed that lack of insight in schizophrenics could include one of the symptoms based on neuropsychological or neurobiological abnormalities in brain. Moreover, it was revealed that patients with poor insight evaluated themselves as having more serious psychopathologies than patients who had insight. It has been already known that schizophrenic patients who lack in insight are reluctant to taking psychiatric care and lack in awareness of their illness. However, this study suggests that their inner psychopathology associated with insight can be understood with the use of subjective psychological test, i.e. K-FBF. For understanding the schizophrenic patients who lack in insight, not only checking the insight but also applying the subjective test such as K-FBF seems to be helpful.

A previously healthy, 3-year-old boy presented to the emergency department with an afebrile focal motor seizure. He was found crying and having a seizure 30 minutes earlier. During this seizure, he was jerking his head and right extremities. Subsequent magnetic resonance imaging showed acute infarction in the bilateral frontal lobes, chiefly in the left. After hospitalization, conventional angiography demonstrated bilateral stenosis of the distal internal carotid arteries with development of lenticulostriate collaterals, which confirmed the diagnosis of moyamoya disease. It is vital to recognize focal motor seizures and situations related to hyperventilation in children with a seizure, which imply a structural lesion and a provoked cerebral ischemia in preexisting moyamoya disease, respectively.
