We report an autopsy case of neonatal giant cell hepatitis that was presumed to be related to bacterial sepsis, endotoxemia and to the subsequent parenteral alimentation and antibiotics treatment. The patient died of candidal endocarditis and multiple brain infarcts. This female baby was born by a normal full term spontaneous delivery. Six days after delivery she developed fever and lethargy as she suffered from Cheyne-Stokes respiration with severe grunting. Blood culture grew Enterobacter and Acinetobacter. After management of the sepsis her general condition improved. On the 23rd day of admission she was found to have deep jaundice and hepatosplenomegaly. The liver became larger progressively and the edge was palpable at the umbilical level. Grade II systolic murmur was heard along the left lower sternal border. She died on the 31st day of hospitalization. Postmortem examination showed severe jaundice, hepatosplenomegaly, a large vegetation on the mitral valve and multiple petechial hemorrhages of the viscera. Microscopically the liver showed features of massive giant cell transformation, mild fibrosis and inflammatory cells, suggestive of giant cell hepatitis. Numerous yeasts and candidal pseudohyphae were seen in the cardiac vegetation, focally extending into the myocardium. There was a focus of candidal vasculitis in the bowel wall. In addition there were multiple bilateral organizing infarcts in the cerebral hemisphere as well as diffuse white matter damage associated with septicemia.

OBJECTIVE: The purpose of this study was to review the clinicopathologic features, recurrent rate, survival rate and controversable issues in the treatment of the ovarian malignant germ cell tumors. PATIENTS AND METHODS: From August, 1991 to November, 1998 thirty-one patients with malignant germ cell tumors of the ovary treated in the department of obstetrics and gynecology, Kosin University Medical college, were eligible and assessable. Demographic characteristics, symptoms, signs, stage, tumor grade, mode of therapy and results of follow up were reviewed retrospectively. RESULTS: The patients with malignant germ cell tumor constituted 6.37% of all ovarian malignancies during this period. Histologic subtypes were 8 dysgerminoma(25.8%), 7 endodermal sinus tumor(22.6%), 10 immature teratoma(32.3%), 3 mixed germ cell tumor(9.7%), 3 choriocarcinoma(9.7%). The age of the patients ranged from 10 to 40 years (mean +/-S.D.; 24.26 +/- 7.51). The most common symptom was abdominal pain(38.7%). Most had stageI(18 cases, 58.0%) or stageIII(5 cases, 16.2%) diseases. All patients underwent surgery as the initial treatment, and nine patients received more than one operation. Postoperative adjuvant chemotherapeutic regimens were VAC, VBP, EP, BEP, EMA, and EMA CO. The mean follow up duration was 26.0(+/- S.D.; +/- 20.3) months. The 2-year and 5-year survival rate were 91.97%(+/- S.E.; +/- 0.05) and 86.86%(+/- S.E.; +/- 0.07).

PURPOSE: To evaluate the role of the MRI after the stereotactic radiofrequency ventralis intermedius nucleus (VIM) thalamotomy for the treatment of tremor. MATERIALS AND METHODS: 156 cases of the postthalamotomy MR findings were analized retrospectively. The sagittal T1 weighted image(WI), axial and coronal Proton and T2WI were obtained by using 0.38 T(Resonex Sunnyvale, U. S. A) machine. The interval between thalamotomy and MR examination was from 3 days to 2 months. The MR characteristics and complications related to thalamotomy were reviewed. In 16 cases, a follow-up MR was done 3 to 13 months after the initial MR study. We also reviewed the follow-up MR findings. RESULTS: The mean size of the thalamus lesion was 16 mm. The thalamus lesions were noted as a single layer in 23 cases and as layers of different signal intensity in 100 cases;(2 layers in 84 cases, and 3 or more layers in 16 cases). In 74 cases of the 84 cases with 2 layers, the inner layer was isointense with gray matter on T1WI, hypointense on T2WI, and the outer layer was hypointense on T1WI, hyperintense on T2WI. There were extrathalamic lesions that were related to mistargetting of stereotactic radiofrequency. The locations of the extrathalamic lesions were the posterior limb of the internal capsule(119 cases), the posterior limb of the internal capsule and the midbrain(39 cases), the posterior limb of the internal capsule and the basal ganglia(11 cases), and the midbrain(9 cases). In 5 cases of the mistargetting, double radiofrequency lesions were visualized because of the repeated coagulation. The other complications were intracerebral hemorrhage(2 cases), subdural hemorrhage(2 cases), epidural hemorrhage(1 case), and intraventricular hemorrhage(1 case). On the follow up MR studies(16 cases), 2 cases showed the hemosiderin deposition in periphery of the lesion. CONCLUSION: The MRI was useful for the evaluation of the thalamic lesions and complications after the stereotactic radiofrequency VIM-thalamotomy for the treatment of tremor.

OBJECTIVE: Mycoplasmas have been implicated in many diseases including cervicitis, urethritis, salpingitis, endometritis... and functioning as cofactors catalyzing the HIV disease state. The oncogenic potentiality of mycoplasma was only recently realized when they were shown causing chromosomal changes and in vitro cell transformations through gradual progressive chromsomal loss and translocation. Few study has been reported the prevalence of mycoplasma infection in human cancers and suggested that there was a connection between these organisms and human cancers. The objective of this study was to determine the relationship between Ureaplasma urealyticum infection and cervical cancer. METHODS: The detection frequency of Ureaplasma urealyticum in 52 invasive cervical cancer tissues and 17 normal cervical tissues was studied using PCR. RESULTS: U. urealyticum DNA was detected in 8 out of 52(15.4%) invasive cervical cancer tissues and 1 out of 17(5.9%) normal cervical tissues. No statistic significance was observed between the detection frequency of Ureaplasma urealyticum and clinicopathologic parameters. The prevalence of Ureaplasma urealyticum in invasive cervical tissues was 15.4% and this rate was higher than 5.9% in normal cervical tissues but there was no statistic significance. CONCLUSIONS: With respect to clinicopathologic parameters of cervical cancer, there was no significant relation between U. urealyticum infection and cervical cancer. There is, however, few study and case on cervical cancer internally and externally. It is considered that more studies on the subject with much cases should be made.

OBJECTIVE: The human MAGE 3 gene encodes tumor specific antigens that are recognized by autologue cytotoxic T lymphocytes (CTL). The MAGE 3 gene is expressed not only in melanoma but in the other malignant tumors as well. There is, however, little information on the expression of the gene in uterine cervical carcinomas. The author thus studied the expression of the MAGE 3 gene products in uterine cervical carcinoma and discuss the possibility of specific immunologic diagnosis using MAGE 3 gene products. METHODS: The expression of MAGE 3 gene product in 17 normal tissues of the cervix, 32 cervical intraepithelial neoplasia (8 CIN I, 10 CIN II, 14 CIS), and 43 invasive cervical carcinomas was studied by immunohistochemistry using anti-MAGE 3 mAb 57B in paraffin sections RESULTS: No expression of MAGE 3 gene product was detected in normal cervical tissues and in cervical intraepithelial neoplasias. The expression of MAGE 3 gene product was detected in 30.2% (13/43) of invasive cervical carcinomas. The MAGE 3 gene product was stained as a cytoplasmic protein in cancer cells. No statistically significant differences were observed between MAGE 3 gene product expression status and clinicopathologic parameters. CONCLUSIONS: The MAGE 3 gene products was expressed in invasive cervical carcinoma tissues.

Recently, Sejong City had been in the center of a policy dispute about city planning in Korea. Although Sejong City was chosen to be a new Multifunctional Administrative City in 2006, politicians continued to challenge the decision at the city level from 2009 upto 2010.This study aims to investigate what influences, such as the policy dispute, impacted the health behaviors and the mental health of local people. We used the survey data from the Community Health Survey in 2008, 2009, 2010, and 2011 and compared the results through logistic regression analysis and direct standardization. Data were gathered from residents in Chungcheongnam-do, the province where Sejong City is located. Data from residents of four other provinces were used as a control: Gangwon-do, Gyeongsangbuk-do, Jeonlanam-do, and Gyeonggi-do. We found a significant increase in smoking and drinking rates in the residents of Chungcheongnam-do, which are indicators of health behaviors, in the year of 2009 when the Sejong City dispute erupted. It appears that controversial changes in government policy could have negative influences on local people. Therefore, we need proper measures to prevent them.

ATP-citrate lyase (ACL), an enzyme catalyzing the first step in biosynthesis of fatty acids, is induced during the lipogenesis and cholesterologenesis. We demonstrate that the region -213 to -128 of human ACL promoter is responsible for conferring glucose-mediated transcription. This region in the ACL promoter contains Sp1 binding sites determined by DNase I foot-printing assay. Gel retardation assay using oligonucleotides from -179 to -141 and -140 to -110 showed two specific DNA-protein complexes postulated to be formed by transcription factor Sp1. Competition gel shift and supershift assays have confirmed that these DNA-protein complexes were the result of induced Sp1 as well as another Sp1-related proteins. Western blot analysis also demonstrated that transcription factor Sp1 was slightly increased in the nuclear proteins extracted from Alexander cells following supplementation of glucose. In addition, expression of 110 kDa protein reacting with antibody against Sp3 was dramatically increased by glucose supplementation, while isoforms of Sp3, about 80 kDa in size was decreased in its amounts. Our results suggest that changes in the expression of Sp1 family proteins play an important role in activation of the ACL promoter by glucose.

Idiopathic scrotal calcinosis is a rare benign disease of scrotal skin, characterized by multiple asymptomatic nodules on the scrotum. The lesions are asymptomatic, round, firm, and yellowish nodules with variable size. Herein, we report a case of idiopathic scrotal calcinosis and a short review of the literature. A 42-year old man presented multiple painless, firm, nodules on his scrotum for about ten years. After excision of the nodules, mixture of calcified material was observed as a typical histological feature of idiopathic scrotal calcinosis.

Background:
Music is regarded as a beneficial tool for assessing the clinical symptoms and communication skills in individuals with autism spectrum disorder (ASD) or autism. The present study developed a music-based attention test (MAT) for individuals with autism using music parameters and the algorithm of the comprehensive attention test (CAT).
Methods:
We recruited 51 autistic individuals and 50 neurotypical individuals to participate in the CAT, MAT, and social intelligence tests. The reliability and validity of the MAT were assessed using exploratory factor analysis, concurrent validity, and criterion-related validity.
Results:
The MAT had sound internal consistency (high Cronbach’s α = 0.948). In addition, the MAT had suitable concurrent validity in the correlation between CAT and MAT, as well as good criterion validity when attention was measured using the MAT and was compared between autistic individuals and neurotypical individuals. Attention evaluated using the MAT was associated with the social quotient in individuals with autism.
Conclusions
The MAT could be a relevant tool for gauging attention in individuals with ASD.Furthermore, attention determined using the MAT may be correlated with social quotient in autistic individuals. Future studies should consider that using music in the field of attention could improve the social quotient of individuals with autism.
