Two Unusual Benign Tumours in Skulls from the Ossuary at Křtiny (Czech Republic)

Among 554 skulls of adult individuals from the ossuary at K𝔯̌tiny, Moravia (late thirteenth to the mid-eighteenth centuryAD ), three (0.54 per cent) showed evidence of malignant tumours and two others (0.36 per cent) had changes suggestive of unusual benign tumours, which are described in the present article. The calvarium of a 20–25-year-old female has two osteoplastic overgrowths in the region of the left tuber parietale and in the left lateral part of the frontal bone. A macroscopic section showed a porotic structure with regularily arranged trabeculae. This was confirmed by radiographic examination, which detected two similar smaller shadows, and by histology and scanning electron microscopy, which showed the non-lamellar, unevenly calcified structure of these curious multiple osteomatous formations (osteomas, hyperostosis). A calvarium of a 40–50-year-old male showed a horseshoe-shaped excavation in the posterior part of the processi palatini of the maxilla, with destruction of the lower half of the nasal septum and the paramedial structures of the nasal cavity. These defects were well delimited macroscopically, radiographically and histologically, and seemed to be the result of pressure atrophy, perhaps from a slow growing benign tumour such as a fibroma or angiofibroma.     

A Case of Osteosarcoma in a Late Medieval–Early Modern Skull from Kyjov (Czech Republic)

After the reconstruction of the original parish church of the Moravian town of Kyjov in the latter part of the seventeenth century, human skeletal remains from the disturbed graves of the surrounding cemetery were gathered in a vault which was partially excavated in 1994. Among disarticulated bones of at least 106 individuals, a fragmented skull of a young male was found, with a massive outgrowth of bone on the right parietal, originally continuing fluently on the non-preserved frontal scale, on edges lifting the outer lamina. The inner lamina was covered less intensively by the bony growth. Radiography and CT scans showed a non-homogeneous structure, the inside being irregular and the outside granulated or radially striated. A metastatic lytic focus was detected in the same bone. Histology and SEM examination showed an uneven mineralization of the bone tissue, consisting of rough, thickened and irregularly spaced trabeculae, with cellular remains or mineralized matrix on the surface. The differential diagnosis took meningioma into consideration but the most probable diagnosis was osteogenic sarcoma, which is still infrequent in the palaeopathological record from the Old World and its localization in the cranial vault is very rare. © 1997 by John Wiley & Sons, Ltd.     

Cronies,economic crime and capitalism in Putin's sistema

The books included in this review article are essential for the understanding of what I call Putin's sistema—the governance model that originated in the Soviet system but has transformed and adapted to global change. Each book tackles, from a different angle, the issues of Russia's transition and suggests ways to describe its political consequences. The books all attempt to identify some underlying logic or organizing force in a Russian society that has emerged through weak institutions. Although I join the authors in their criticisms of the ‘transition paradigm’ and its ‘opening‐breakthrough‐consolidation of democracy’ formula, transformations of the Soviet sistema seem to resonate with the ‘opening‐breakthrough‐consolidation of capitalism’. Perestroika can be seen as an ‘opening’ in shaking the foundations of sistema; Yeltsin's era as a ‘breakthrough’; and Putin's regime as the ‘consolidation’ of capitalism but with its distinct characteristics.
