Mullerian adenosarcoma is an uncommon variant of MQllerian mixed tumors of the uterus and a mixed, biphasic neoplasia in which the mesenchymal component is malignant and the epithelial component is benign. In contrast to typical malignant Miillerian mixed tumor(MMMT), Miillerian adenosarcomas are usually tumors of low malignant potential. These tumom usually present as pedunculated endometrial masses in postmenopausal women with vaginal bleeding. We experienced a case of Miillerian adenosarcoma of the uterus with squamous cell carcinoma of the uterine cervix and report with a brief review of literatures.

Although cystic teratoma is the most common benign tumor of the ovary, the association of sebaceous gland tumor with cystic teratoma is rare. We have recently experienced a case of sebaceous gland tumor, arising in the cystic teratoma of the ovary in a 78-year-old Korean woman. Histologically, the tumor was characterized by an organoid lobular architectures of the sebaceous glands which are exculsively composed of germinative and mature sebaceous cells. Although it is difficult to come to a valid conclusion due to the presence of atypical mitosis and necrosis, this tumor was regarded as benign from the viewpoint of preserved organoid structures, and absence of capsular invasion or metastasis.

Hantavirus is a genus of the Bunyaviridae family causing two serious diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Puumala virus is a member of hantavirus originally found in Europe, and its natural reservoir is Clethrionomys glareolus. It is also associated with the hurnan disease nephropathia epidemica, a milder form of HFRS. To identify the hantaviruses in bats, bats were collected from Jeong-Sun, Won-Joo, Chung-Ju and Hwa-Cheon area in Korea, and nested RT-PCR was performed with serotype specific primer from M segment. Interestingly, Puumala virus was detected in bats (Rhinolophus ferrum-equinum) only from Won-Joo. The 327 bp nested RT-PCR product, was sequenced. The sequence database search indicates that the sequence is homologous to the published sequence of Puumala viruses. The sequence similarities were ranged from 71% to 97%. The highest sequence similarity was 97% with Puumala virus Vranicam strain, and the lowest was 71% with Puumala virus K27 isolate. Puumala virus Vranicam strain was isolated from a bank vole (Clethrionomys glareolus) in Bosnia-Hercegovina. Puumala virus K27 was isolated from human in Russia. This analysis confirms that bats (Rhinolophus ferrum-equinum) in Korea are natural reservoir of Puumala virus.

A multiple regression analysis using ordinary least square (OLS) is frequently used for the projection of healt expenditure as well as for the identification of factors affecting health care costs. Data for the analysis often have mixed characteristics of time series and cross section. Parameters as a result of OLS estimation, in this case, are no longer the best linear unbiased estimators (BLUE) because the data do not satisfy basic assumptions of regression analysis. The study theoretically examined statistical problems induced when OLS estimation was applied with the time series cross section data. Then both the OLS regression and time series cross section regression (TSCS regression) were applied to the same empirical data. Finally, the difference in parameters between the two estimations were explained through residual analysis.

Total hip arthroplasty(THA) is applied to various hip diseases, and the results are different according to the disease entities. We have made the functional evaluation of three groups of the patients who had undergone THA in Seoul National University Hospital from 1981 to 1990: the first group-fused hips (28 hips of 27 patients), the second group partially ankylotic hips whose total range of motion were less than 60°(46 hips of 46 patients), and the third group-hips of ankylosing spondylitis (22 hips of 14 patients). The results were summerized as follows: No statistically significant difference was seen in the postoperative average Harris hip score between three groups. In the postoperative average range of motion, statistically significant difference was seen only between the first and second groups. Therefore, similar clinical results can be obtained from the THA in the fused hips to those of the partially ankylotic hips such as tuberculous or septic hip sequelae.
