Expression of p27 and p53: comparative analysis of uterine carcinosarcoma and endometrial carcinoma

The aim of the study was to assess both p27 and p53 expression in the stromal and epithelial component of carcinosarcoma and to assess if their expression in the latter is different than in endometrial carcinoma. Immunohistochemical staining for p27 and p53 was performed on paraffin-embedded tissue blocks of 18 uterine specimens with carcinosarcoma and their expression assessed. Their expression in the epithelial element was also compared to that in 35 paraffin-embedded tissue blocks of endometrial endometrioid carcinoma. Reduced p27 expression was observed in a similarly high proportion of the stromal (77.8%) as well as of the epithelial component (66.7%) of carcinosarcoma. Although statistically not significant, the proportion of reduced p27 expression in endometrial carcinoma (85.7%) was higher than in the epithelial element of carcinosarcoma. The percentage of p53 overexpression in both elements of carcinosarcomas and in endometrial carcinomas was low and also similar (27.8 and 20.0%, respectively). Our results indicate that reduced p27 expression is common and p53 overexpression is infrequent in carcinosarcoma. Their similar rates of expression in the stromal and epithelial elements of the tumor support the contention of a monoclonal origin of carcinosarcoma. Unexpectedly, reduced p27 expression is more common in endometrial carcinoma than in the epithelial element of carcinosarcoma, in spite of the less favorable prognosticators and outcome in the latter. Further studies of p27 expression in carcinosarcoma are indicated to establish its clinical value in this aggressive malignancy.     

Attitudes Toward Transplantation in U.K. Muslim Indo-Asians in West London

The worldwide shortage of organs for transplantation makes it important to understand why some oppose donation. Attitudes vary with religion and ethnicity. Accordingly, we undertook a qualitative study of the attitudes of 141 U.K. Muslim Indo-Asians to organ donation. Participants were observed, focus group discussions held and in-depth individual interviews conducted. We identified a high level of alienation from the health care system in general. With respect to organ donation in particular, its importance was generally discounted, often in deference to authority figures within the community who appeared negatively disposed. The culture-specific issues arguing against donation included a sense of the sacredness of the body, a fatalistic approach to illness, a belief that organs took on an independent role as 'witnesses' to an individual's life on Judgement Day and an anxiety that the donor would have no control of the probity of the recipient of an organ. We believe these data suggest a need to improve in a culturally sensitive fashion the provision of health information provided to this community.     

Right atrial aneurysm: case report.

We report the case of a 49-year-old patient, with recent onset of fatigue, who was diagnosed with atrial fibrillation, which was cardioverted electrically. A diagnosis of right atrial aneurysm, with no other cardiac pathology, was made. An aneurysmectomy was performed. Both surgery and postoperative recovery were uneventful.     

Description and prognostic value of cerebellar MRI lesions in children with severe acute ataxia]

The aim of this work was to evaluate NMR cerebellar abnormalities in children with severe acute ataxia. Among 8 consecutively observed children, NMR performed in 6 during the acute phase was pathological in 4, demonstrating hyperintense signal in the T2-weighed sequences of dentate nuclei (2 cases, associated in 1 with hyperintense signal in the medium cerebellar peduncle) or of the cerebellar cortex associated with cerebellar swelling (2 cases). NMR performed in 7 cases after at least 1 month of evolution showed cerebellar atrophy in 4 cases. After 1 to 6 years of clinical follow-up, 4/8 children had clinical sequellae, including 3 of the 4 children with initially abnormal NMR. Conversely, the 2 patients with initially normal NMR had a good clinical recovery. NMR during the acute phase gives informations on prognosis in patients with severe acute ataxia.
