Segmental dilatation of small intestine or colon can induce signs of intestinal obstruction, such as abdominal distension, vomiting and constipation. There are no anatomical gross obstructive lesions, and moreover, ganglion cells are observed in both dilated and undilated distal segments of the intestine. It often accompanied by other congenital anomalies. We reported two cases of segmental dilatation of the intestine in the newborn infants, one in small intestine and the other in colon, with brief review of the related literatures.

Central nervous system involvement in multiple myeloma (CNS-MM) is a rare condition. Various manifestations of CNS-MM have been reported, including dural, parenchymal, and leptomeningeal involvement. Among them, leptomeningeal involvement is less common and intraventricular involvement is exceptional, with only one case reported in the literature. Herein, we report the first case of CNS-MM manifesting as an intraventricular mass with leptomeningeal involvement combined with perineural spread. We also describe characteristic computed tomography and magnetic resonance imaging findings of intraventricular multiple myeloma.

Fourty-seven patients with non-aneurysmal spontaneous subarachnoid hemorrhage were reviewed retrospectively. Attention was directed to the distribution and amount of subarachnoid hemorrhage on computerized tomography scans. Though the hemorrhage could be distributed in all cisterns, the frequency and amount of hemorrhage were higher in infratentorial cisterns than in supratentorial cisterns. Among infratentorial cisterns, the hemorrhage was distributed to cisterns around the brain-stem mainly and it had a predilection for interpeduncular cistern. Also the telangiectasia of thalamoperforating artery might be one of the causes of non-aneurysmal spontaneous subarachnoid hemorrhage.

Mutations in the tumor suppressor p53 gene are the most frequently observed genetic lesions in human cancers. It seems that wild type p53 does significant role on growth and differentiation of normal cells, Mutations and allelic loss of the p53 gene are thought to be a cause of tumor development and to be correlated with the prognostic factors in various human cancers such as breast, ovary and lung cancer. Mutant p53 proteins have a prolonged half-life and can be detected by immunohistochemistry. In case of GTD(gestational trophoblastic disease), although the mutation of p53 gene mutation was revealed to be very rare, the overexpression of p53 in immunohistochemical staining has been reported in wide range of discrepancy and its role or prognostic significance in GTD is uncertain. This study is performed to define the status of p53 overexpression in GTD and to evaluate the correlations between p53 overexpression and prognostic factors of GTD. THE RESULTS WERE AS FOLLOWS: 1. p53 overexpression was detected in none of normal placental tissue, in 58.3%(14/24) of hydatidiform mole, in 15%(6/8) of invasive mole, in 75%(3/4) of choriocarcinoma, and in 100%(1/1) of placental site trophoblastic tumor, and showed significant difference between normal placenta and GTD. We could not find any difference of the p53 overexpression between benign group(H-mole) of GTD and malignant one(invasive mole, choriocarcinoma, and placental site trophoblastic tumor) 2. In H-mole, low-risk group showed significantly higher prevalence of p53 overexpression than high-risk group did. In malignant group, there is no difference in the prevalence of p53 overexpression between early(FIGO stage I) and late(II- IV)stage-diseases, but the prevalence of p53 overexpression of low-risk group is slightly higher than that of high-risk group although we failed to find statistical significance. In conclusion, the high prevalence of p53 overexpression in GTD suggests that p53 may have a certain role in the pathogenesis of GTD or at least represent generalized DNA damage or genetic instability of GTD. And the higher prevalence of p53 overexpression in low-risk group suggests that accumulation of wild-type p53 may be related with favorable prognosis in GTD.
