We report a case of giant cell tumor of the tendon sheath involving the foot, in a 21-year-old female patient, who presented with an asymptomatic tumor on the dorsum of her right foot. Histopathologically the tumor is surrounded by thin fibrous connective tissue. The characteristic findings of the excised specimen revealed a typical mixture of abundunt round or polygonal histocyte-like cells with varying portions of spindle-shaped fibroblast-like cells and multinucleated giant cells. Variable amounts of hyalinized fibrous stromal tissue were also present. After excision, local recurrence has not been observed for 3 months.

A sample size with sufficient statistical power is critical to the success of genetic association studies to detect causal genes of human complex diseases. Genome-wide association studies require much larger sample sizes to achieve an adequate statistical power. We estimated the statistical power with increasing numbers of markers analyzed and compared the sample sizes that were required in case-control studies and case-parent studies. We computed the effective sample size and statistical power using Genetic Power Calculator. An analysis using a larger number of markers requires a larger sample size. Testing a single-nucleotide polymorphism (SNP) marker requires 248 cases, while testing 500,000 SNPs and 1 million markers requires 1,206 cases and 1,255 cases, respectively, under the assumption of an odds ratio of 2, 5% disease prevalence, 5% minor allele frequency, complete linkage disequilibrium (LD), 1:1 case/control ratio, and a 5% error rate in an allelic test. Under a dominant model, a smaller sample size is required to achieve 80% power than other genetic models. We found that a much lower sample size was required with a strong effect size, common SNP, and increased LD. In addition, studying a common disease in a case-control study of a 1:4 case-control ratio is one way to achieve higher statistical power. We also found that case-parent studies require more samples than case-control studies. Although we have not covered all plausible cases in study design, the estimates of sample size and statistical power computed under various assumptions in this study may be useful to determine the sample size in designing a population-based genetic association study.

Zygomatic fractures are the second most common facial bone fractures encountered and treated by plastic surgeons. Stable fixation of fractured fragments after adequate exposure is critical for ensuring three-dimensional anatomic reduction. Between January 2008 and December 2010, 17 patients with zygomatic fractures were admitted to our hospital; there were 15 male and 2 female patients. The average age of the patients was 41 years (range, 19 to 75 years). We exposed the inferior orbital rim and zygomatic complex through a lateral brow, intraoral, and subciliary incisions, which allowed for visualization of the bone, and then the fractured parts were corrected using the Carroll-Girard T-bar screw. Postoperative complications such as malar asymmetry, diplopia, enophthalmos, and postoperative infection were not observed. Lower eyelid retraction and temporary ectropion occurred in 1 of the 17 patients. Functional and cosmetic results were excellent in nearly all of the cases. In this report, we describe using the Carroll-Girard T-bar screw for the reduction of zygomatic fractures. Because this instrument is easy to use and can rotate to any direction and vector, it can be used to correct displaced zygomatic bone more accurately and safely than other devices, without leaving facial scars.

Thirty nine cases of multiple primary malignant tumors examined at the Department of Pathology, Keimyung University School of Medicine during the period from November 1974 through March 1986 were analysed clinicopathologically. The findings are as follows: 1) Thirty nine cases had synchronous lesion and six cases metachronous lesion. The second primary malignancy occurred mean 4.7 years after the first malignancy in patients with metachronous lesion. 2) The age at diagnosis of the first malignancy ranged from 26 to 76 years, the average being 51.8 years. The male-female ratio was slightly less than 1:1.2. 3) The most commonly involved site in multicentric origin was gastrointestinal tract (44.4%) with all adenocarcinoma and the second urogenital system (29.6%). In cases of different tissues or organs (11 cases), ovary was the most frequent site (5 cases), followed by cervix (4 cases). 4) Multiple primary malignant tumors of urogenital system were all eight cases and six cases among them (75%) had smoking and drinking habits. 5) The detailed informations about possible environmental, familial and host factors necessary for the investigation of multiple primary tumors were lacking in most cases. Therefore, the history taking with special attention to these factors must be carefully recorded. And also, we suggest that in the high-risk individuals, careful follow-up and thorough search for early cancer detection or prevention should be taken.

In order to product and develop questionnaire which can assess the schizotypal personality by model of criteria in DSM-III-R it was presented 1311owing questions in this study. First, far the validation and manufacture of scale and sub-subscale that assess overall feature, nine characteristics of the schizotypal personality disorder, this study was concerned with validity, reliability and factor-analysis results of schizotypal personality questionnaire. Second, we would be present how schizotypal personality disorder trend is connected with trait-anxiety, hopelessness and self-concept. Also the difference Is compared with. Finally, 396(male 216 Ss/53,8%, female 180 Ss/45.5%) college students with mean age 21.2 years were sampled. Raine's schizotypal personality questionnaire(SOQ) which assess nine characterisitics of schizotypal personality disorder in DSM-III-R was translated and used. In this results, Raine's schizotypal personality questionnaire was appeared to have high internal validity, split-half reliability and test-retest reliability Also, 6 factors were affirmed by empirical confirmation through factor-analysis. 6 factors have been very reliable internal validity that ranges from .78 to .83. In these 6 factors, idea of reference, odd or eccentric behavior and odd speech were corresponded to the category model after DSM-III-B in Raine's scale. 'Cognitive, perceptive' dimension was centered of factor 1, 'Emotive, affective' dimension was centered of factor 2, social anxiety and constricted affect were constituted to 2nd factor. No close friends, schizoid trend and suspiciousness of schizotypal characteristics were constituted to 3rd factor by' interpersonal relationship' dimension. These empirical outcomes which confirmed through factor-analysis were very valid and connected much to Raine's scale which assessed schizotypal personality disorder, thus possibility of development and manufacture of schizotypal personality disorder scale through item revision was lighten. In 2nd study the higher schizotypal personality disorder trend, trait-anxiety and hoplessness were higher. But on the contrary, self-concept was lower. The group of high score in schizotypal personality questionnaire had more trait-anxiety and hopelessness than the group of low score in schizotypal personality questionnaire. Contrastly, positive self-concept was high in the group of low score. Also, the most predictable variable to the trait-anxiety was factor 2, predictable power R2 of factor 2 was 29.1%. To the hopelessness, factor 2 was the most powerful predictable variable. Predictable power of factor 2 was 11.2%, also. In self-concept, factor 2 explained 20.8% of self-concept, thus it was presented that factor 2 had the most powerful explanatory quantity. In these consequences, the factors which have meaningful connection to the trait-anxiety, hopelessness and low self-concept within 6 factors were really factor 2, 3, 1. Among these factors, 'Emotive' feature of factor 2 including social anxiety and constricted affect have the most effect on trait-anxiety, hopelessness and serf-concept. And next to factor 2, the isolated interpersonal relation which include no close friends and schizoid trend was some influential variable. Also peculiar, unusual perceptual experience, eccentric belief and magical thinking had some effect though small. The college students who had strong schizotypal personality trend had more social anxiety and more constricted emotional empathic ability, less self-expression, less social skill than common college students. These elements threaten, interrupt and retard identity establishment and intimacy-seeking which are important developmental tasks within this period. These experiences is accepted to ego-dystonic to schizotypal college students who have some or moderate reality testing, adaptive ability. Moreover, These peoples would feel locus of control externally, not internally and would have more control-failure experiences. All these elements elevate anxiety level, give rise to low self-concept and low expectation to the future. These outcomes all confirmed questions which presented in this study.
