We measured the bone ingrowth rate on 22 retrieved human cementless porous coated acetabular cups by the help of computer graphics. All the acetabular cups had functioned well, and had had evidence of radiologic bony ingrowth before revising the acetabular cup. The reason for retrieval of the acetabular cups were: one with habitual dislocation, who with stem loosening, and 19 with polyethylene cup wearing. The period from initial surgery to retrieval surgery was 28 months to 108 months(average 56.1 months). All the retrieved porous coated acetabular cups showed macroscophic bony ingrowth, and the ratio of the whole porous surface to bony ingrowth area was showed 1.14% to 92.27% (average 36%).

This paper shows anthropometric differences among four regions of urban community using Korean anthropometric data surveyed in 1992. The anthropometric data include 84 measurements of Korean aged 12~50. The principal component analysis reduce 84 measures to five components. The discriminant analysis using these components is performed to observe the anthropometric differences among four regions : Seoul and Kyungki, Kangwon and Chungbuk, Chungnam and Ch lla, Kyungsang. The results on age groups (12~14, 15~17, 18~24, 25~50 ages) and city size (big city, medium city, small city) can be summarized as follows ; 1) In male aged 12~14 and 15~17, there are significant differences of anthropometry among four regions in all city size. But in another age groups (18~24 and 25~50 ages), these are not significant differences of anthropometry among four regions except medium city. 2) In female, there are significant differences of anthropometry in all city sloe in aged 18~24 and 25~50 and in medium city in aged 15~17. however, there are not significant differences in aged 12~14 and 15-17.

Angiomyolipoma is considered by many authors to be a hamartoma, occurring in a sporadic form or in association with tuberous sclerosis. This lesion consists of thick walled blood vessels, smooth muscle, and mature adipose tissue in varying amounts. We have experienced a case of the angiomyolipoma composed of monotypic epithelioid cells. The patient was a 69-year-old female. Clinically, there was no evidence of tuberous sclerosis. Microscopically, the tumor was composed of polygonal cells with abundant eosinophilic granular or clear cytoplasm, pleomorphic nuclei, prominent nucleoli, and multinucleated giant cells. The tumor cells showed positive reaction for HMB45, CD68, smooth muscle actin, and S-100, and negative reaction for epithelial membrane antigen, cytokeratin, vimentin, desmin, CD34, estrogen receptor, and progesterone receptor. Ultrastructual analysis showed the presence of glycogen, mitochondria, and other microorganelles in neoplastic cells. Melanosome or premelanosome was not identified.

Adding either macrolide or fluoroquinolone (FQ) to β-lactam has been recommended for patients with severe community-acquired pneumonia (CAP). However, due to the limited evidence available, there is a question as to the superiority of the two combination therapies. The MEDLINE, EMBASE, Cochrane Central Register, Scopus, and Web of Science databases were searched for systematic review and meta-analysis. A total of eight trials were analyzed. The total number of patients in the β-lactam plus macrolide (BL-M) and β-lactam plus fluoroquinolone (BL-F) groups was 2,273 and 1,600, respectively. Overall mortality of the BL-M group was lower than that of the BL-F group (19.4% vs. 26.8%), which showed statistical significance (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.49 to 0.94; P = 0.02). Length of hospital stay was reduced in the BL-M group compared to the BL-F group (mean difference, −3.05 days; 95% CI, −6.01 to −0.09; P = 0.04). However, there was no significant difference in length of intensive care unit (ICU) stay between the two groups. Among patients with severe CAP, BL-M therapy may better reduce overall mortality and length of hospital stay than BL-F therapy. However, we could not elicit strong conclusions from the available trials due to high risk of bias and methodological limitations.
