[Value of postmortem computed tomography in comparison to autopsy].

Purpose: To assess the diagnostic value of postmortem computed tomography (CT) in comparison to autopsy.

Materials And Methods: Twenty-seven cadavers were examined by sequential cranial CT and helical CT through the neck, thorax and abdomen and subsequently underwent an autopsy with histomorphologic examination of the pathologic specimens. The findings of CT, autopsy and histology were registered and compared by three radiologists and one specialist for forensic medicine, using a data entry form.

[Color duplex sonographic findings in an iatrogenic arteriovenous fistula of the vertebral artery].

The report describes a rare case of an iatrogenic arteriovenous fistula of the vertebral artery to the vertebral vein which arose after insertion of a central venous catheter via the jugular vein. We give special attention to the role of colour duplex sonography in the primary diagnosis of such fistulas. As can be seen from published reports with this non-invasive examination, the diagnosis of fistulas could not be established in all cases, where an abnormal communication between the vessels was later revealed by angiography.

Megakaryopoiesis and myelofibrosis in chronic myeloid leukemia after allogeneic bone marrow transplantation: an immunohistochemical study of 127 patients.

An immunohistochemical and morphometric study was performed on 363 trephine biopsies of the bone marrow derived from 127 patients with chronic myeloid leukemia at standardized end points before and after allogeneic bone marrow transplantation (BMT). The purpose of this investigation was to evaluate features of CD61+ megakaryopoiesis related to successful engraftment. Further, we tried to elucidate possible associations of this lineage, including precursor cells, with the platelet count and reticulin fibrosis during the pretransplant and, specifically, post-transplant periods.
