Genetic and clinical observations were recorded on 16 patients with xeroderma pigmentosum, 14 of them having visited the Department of Dermatology, Chonnam National University Hospital, Kwangju, Korea from 1968 through 1982, and 3 of them having visited the Department of Dermatology, Chosun University Hospital located in the same city during same period(one patient was duplicated). Xeroderma pigmentosum was found to occur with a frequency higher than one in 183,000 births in Chonnam province, Korea. It waa recognized that xeroderma pigmentosum is a disease of autosomal recessive inheritance. The sex ratio of xeroderma pigmentosum was male to female l. 7 to 1. The age of onset was between 5 months and 10 years, and the age when the patients visited the hospital for the first time was 6 months and 25 years. The skin malignancies were observed in 9 patients, among which squamous cell carcinomas occurred in 6, basal cell carcinomas in 2, and actinic keratosis in l. The associated ocular abnormalities were photophobia in 4 patients, chalazion in 1, blepharoconjunctivitis in 1, pterygium in 1 and squamous cell carcinomas in 1. Only cerebral galsy as a neurological abnormality was observed in 1 patient.

We report a case of fine needle aspiration cytology of endodermal sinus tumor of the ovary. A 13-year-old girl complained of abdominal mass and pain. The abdominal sonography revealed a well-demarcated huge mass, which was solid and multiseptated. Percutaneous fine needle aspiration was performed from the mass. The smears revealed moderate cellularity, which was arranged in sheets or clumps of pleomorphic malignant cells on mucoid background. The valuable characteristic features of tumor cells were papillary configuration, vacuolated cytoplasm and intracellular and extracellular hyaline globules. The diagnosis was confirmed later by histologic study of surgical resection of the specimen.

T cell lymphoblastic lymphoma is characterized by immature lymphoid cells that are indistinguishable from the lymphoblasts and prolymphocytes of acute lymphoblastic leukemia. Several characteristic clinical features of lymphoblastic lymphoma, with include a high male-to-female ratio, a relatively high incidence in older children and young adults, the frequent presence of mediastinal involvement at the time of diagnosis. Also, this disease is rapidly progressive, and early dissemination to the bone marrow, blood, and central nervous system leads to the evolution of a picture resembling a acute lymphoblastic leukemia. We have experienced a rare case of congenital T-cell lymphoblastic lymphoma in which 1/365 year old female newborn had generalized multiple irregular protruding mass on her body. On bone marrow biopsy, CSF analysis, ultrasonogram and whole body MRI studies. We found metastasized tumor mass to, orbit, abdominal cavity, bulva, skin, and lower extremities. Histopathologically, specimen from mass on the right thigh showed diffuse infiltration of poorly differentiated and immature lymphoid cells in the skelectal muscle and subcutaneous soft tissue. By immunophenotyping studies using anti T cell and B cell monoclonal antibody, these cells were reactive with UCHL-1, MB2, but unreactive with MB1, L26. Based on these findings, the lesion was diagnosed as lymphoblastic lymphoma of the T-cell type, which occurred congenitally. Most T cell lymphoblastic lymphoma are noted, but congenital case was not reported. So we report it with a brief review of literature.

Urinary cytology has become an essential element in the diagnosis and management of transitional cell carcinoma(TCC) of the urinary tract. It has the advantage of being noninvasive, inexpensive, and easily accessible. Besides that it can even detect malignancy when unsuspected at cystoscopy. We report a retrospective review of urine cytology in the diagnosis of 83 TCC cases that underwent 295 cytologic evaluation. All patients had biopsy-proven TCC of the bladder, ureter and renal pelvis. The overall inci- dence of the positive cytology cases was 66.2%. To define the cytologic features of tumor cells, we tried to use three cytologic gradings such as "grade 1", "grade 2", and "grade 3" according to the cytologic degree of anaplastic neoplastic cells. These cytologic gades of TCC were relatively well correlated with the histologic grade and tumor invasiveness. This result suggests that the recognition of characteristic cellular features of TCC can suspect the histologic grade and tumor stage. The false negative TCC cases were 78.9%. They showed severe inflammatory or bloody background and a few neoplastic cells. Therefore, a cautious approach for accurate interpretation, personal experience, and proper fixation and processing could expand the role of urinary cytology.

Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

PURPOSE: Unlike murine oncoretroviruses which can infect only dividing cells, lentiviral vector based on HIV have been shown to efficiently transfer genetic materials into a various cells which makes lentiviral-based vector systems promising candidates for clinical gene therapy, but have also raised safety concerns because of potential creation of replication-competent lentivirus (RCL) by uncontrolled recombination. In this study, I intended to validate RT-PCR assay for detection of replication-competent virus (RCV) in vector preparations using HIV vector based gene delivery system. METHODS: We prepared a replication-competent lentiviral supernatant from a 293T cell line which had been transfected with plasmid pHIV-VSV G-IRES-eYFP as a positive control, by introducing VSV-G into a first-generation HIV-based vector. A variant of this virus, which has additional deletions of vif and vpr was also used as another positive control. As a negative control, VSV-G pseudotyped HIV-based vector encoding YFP was used. These viruses encode enhanced yellow fluorescent protein (eYFP). I used reverse transcriptase (RT)-PCR to detect VSV-G RNA sequences contained within viral supernatants produced from transiently transfected 293T cells using oligonucleotides specific for conserved for VSV-G element. RESULTS: After production in 293T cells, titer of each virus were<107 IU/mL. eYFP expression in 293T cells increased according to passage with extremely fluorescent with replication-competent vector. Correctly-sized DNA products was always detected, even when using supernatants from cells separately transfected with VSV-G and replication-defective HIV. CONCLUSION: These data suggested that RT-PCR based method is not appropriate for transient transfection of producers where cell lysis is routine. Instead we turned our attention to the development of other sensitive assays.

PURPOSE: The purpose of this study was to investigate the relationship among family functioning, empathy and aggression by high school students. METHODS: This was a descriptive study. The survey participants were 467 high school students from M city. Data were collected from November 29 to December 7, 2012 and self-report questionnaires including a Family Adaptability Cohesion Evaluation Scale, Interpersonal Reactivity Indexes, and an Aggression Questionnaire. The collected data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, stepwise multiple regression. RESULTS: The majority of the subjects were 2nd graders (42.0%) and female (57.2%). 59.7% of the subjects had religion, 84.8% were living together with parents. The mean ages of their fathers and mothers were 49.90+/-0.20 and 46.85+/-0.19 respectively. Aggression was found to have a statistically negative correlation with family functioning and empathy. Stepwise multiple regression analysis revealed that the most powerful predictor of aggression was empathic concern. Empathic concern, family cohesiveness, perspective taking, personal distress and gender accounted for 16.7% of the variances. CONCLUSION: It is necessary to provide aggressiveness reduction programs for high school students that consider their family functioning and empathy.
