Secondary osteoarthritis of hip joints is a common disease and is frequently followed by chronic sublexation and dislocation. Twenty four case of the secondary osteoarthritis associated with chronic subluxation and dislocation of the hip joints were evaluated with plain radiography and computed tomography. We retrospectively analyzed 1) the ossification and calcification of the acetabular labrum, 2) the thickeness of the quadrilateral plate of the ilium, and 3) anteroposterior diameter of the acetabulum. The changes of the hip joints in subluxation (n=14) revealed ossification of the acetabular labrum in 12 cases (86%), thickening of the quadrilateral plate of the ilium in 11 cases (78%) but anteroposterior diameter of the acetabulum was not changed. The changes of the hip joints in dislocation (n=10) revealed no evidence of the ossification of the acetabular labrum, thickening of the quadrilateral plate of the ilium in 10 cases (100%) and decreased anteroposterior diameter of the acetabulum. We conclude that CT findings of subluxation and dislocation of the hip joints can be helpful in the evaluation of the secondary osteoarthritis of the hip joints.

PURPOSE: This study evaluated the treatment effectiveness and proper radiation dose of helical tomotherapy (HT) in spine oligometastases from gastrointestinal cancers. MATERIALS AND METHODS: From 2006 to 2010, 20 gastrointestinal cancer patients were treated with HT for spine oligometastases (31 spine lesions). The gross tumor volume (GTV) was the tumor evident from magnetic resonance imaging images fused with simulation computed tomography images. Clinical target volume (CTV) encompassed involved vertebral bodies or dorsal elements. We assumed that the planning target volume was equal to the CTV. We assessed local control rate after HT for 31 spine metastases. Pain response was scored by using a numeric pain intensity scale (NPIS, from 0 to 10). RESULTS: Spine metastatic lesions were treated with median dose of 40 Gy (range, 24 to 51 Gy) and median 5 Gy per fraction (range, 2.5 to 8 Gy) to GTV with median 8 fractions (range, 3 to 20 fraction). Median biologically equivalent dose (BED, alpha/beta = 10 Gy) was 52 Gy10 (range, 37.5 to 76.8 Gy10) to GTV. Six month local control rate for spine metastasis was 90.3%. Overall infield failure rate was 15% and outfield failure rate was 75%. Most patients showed pain relief after HT (93.8%). Median local recurrence free survival was 3 months. BED over 57 Gy10 and oligometastases were identified as prognostic factors associated with improved local progression free survival (p = 0.012, p = 0.041). CONCLUSION: HT was capable of delivering higher BED to metastatic lesions in close proximity of the spinal cord. Spine metastases from gastrointestinal tumors were sensitive to high dose radiation, and BED (alpha/beta = 10 Gy) higher than 57 Gy10 could improve local control.

PURPOSE: The prognosis of stage IV stomach cancer patients is very poor and the effectiveness of radical surgery including extended lymphadenectomy and combined resection in these patients is still controversial. The purposes of this retrospective study were to identify the prognostic factors and to evaluate the effectiveness of extended lymphadenectomy and combined resection in stage IV stomach cancer paients. MATERIALS AND METHODS: Of 585 patients who were operated for stomach cancer at the NMC from Jan. 1987 to Oct. 1993, 154 patients of stage IV stomach cancer (121 patients who had distant metastasis and 33 patients who had not) were identified. We analyzed data of these 154 patients to find the characteristic clinicopathological features, the prognostic factors and the proper extent of surgical treatment. RESULTS: Comparing with stage I, II and III groups, larger tumor size, higher proportions of Borrmann type IV and undifferentiated carcinoma and higher rates of lymph node metastasis and combined resection were noticed in stage IV stomach cancer group. In combined resection, pancreas tail was mainly resected due to tumor invasion but spleen was mainly resected for the completeness of lymph node dissection. In multivariate analyses, peritoneal metastasis and postoperative residual tumor were independent prognostic factors. The overall 5-year survival rate was 14.6%. Stage IV stomach cancer patients without distant metastasis had better 5-year survival rate than that of those who had distant metastasis (34.3% vs 7.9%, p=0.00001). CONCLUSIONS: Radical procedures including extended lymphadenectomy and combined resection of the invaded organs should be considered in the stage IV stomach cancer patients without distant metastasis.

Orientia tsutsugamushi is obligate intracellular bacterium that grows within the cytoplasm of the eukaryotic host cells. Therefore capability of the attachment, entry into the host cell and intracellular survival should be critical process for oriential infection. In this study we investigated the cellular invasion mechanism of Orientia tsutsugamushi and the role of transmembrane heparan sulfate proteoglycan, which binds diverse components at the cellular microenvironment and is implicated as host cell receptors for a variety of microbial pathogens. First of all Orientia tsutsugamushi can invade a wide range of nonprofessional phagocytic cells including fibroblast, epithelial cells a#nd endothelial cells of various host species, including B and T lymphocytes. Thus, it was postulated that the attachment of O. tsutsugamushi requires the recognition of ubiquitous surface structures of many kinds of host cells. Treatments with heparan sulfate and heparin inhibited the infection of Orientia tsutsugamushi in dose-dependent manner for L cell, mouse fibroblast, whereas other glycosaminoglycans such as chondroitin sulfate had no effect. Collectively, these findings provide strong evidence that initial interaction with heparan sulfate proteoglycan is required for the oriential invasion into host cells.

10.Miller-Bicker Syndrome.

Miller-Dieter syndrome consists of severe type I lissencephaly, abnormal facial appearance, and sometimes other birth defects. Lissencephaly is a brain malformation manifested by a smooth cerebral surface, thickened cortical mantle, and microscopic evidence of incomplete neuronal migration. It comprises the agyria-pachygyria spectrum of malformation, thus excluding polymicrogyria and other cortical dysplasia. Type I lissencephaly results from abnormal migration between about 10 and 14 weeks gestaion. The brain is often small, and the ventricle is enlarged posteriorly The corpus callosum may be small or absent. The structural pattern of the cerebral hemispheres and ventricles is distintly immature, reminiscent of fetal brain. The superficial cellular layer resembles an immature cortex, with some separation into zones similar to layers III, V, and VI of normal cortex, although the cell population is decreased. In 1963 Miller described a malformation syndrome in a brother and sister with postnatal growth deficiency, craniofacial defects, and serious abnormalities of neurologic function. Autopsy at 3 and 4month of age, respectively, revealed lissencephaly. Subsequently, Dieker reported four additional patients with this disorder and referred to it as the 'lissencephaly syndrome'. We have experienced a case with this syndrome. Then we report this rare case with brief review of literature.
