    Notes: Abstract Central to the oxidative stress hypothesis of Parkinson’s disease (PD) pathogenesis is the ability of iron to generate hydroxyl radicals via the Fenton reaction, and the consistent demonstration of iron elevation in the pars compacta region of the substantia nigra. However, uncertainty exists as to whether the excess iron exists in a state suitable for redox chemistry. Here, using a method we developed that detects redox-active iron in situ, we were able to demonstrate strong labeling of Lewy bodies in substantia nigra pars compacta neurons in PD. In contrast, cortical Lewy bodies in cases of Lewy body variant of Alzheimer’s disease were unstained. While the presence of elevated iron in PD substantiates the oxidative stress hypothesis, one must remember that these are viable neurons, indicating that Lewy bodies may act to sequester iron in PD brains in a protective, rather than degenerative, mechanism. The absence of redox-active iron in neocortical Lewy bodies highlights a fundamental difference between cortical and brain stem Lewy bodies.

    Notes: Abstract. Fibroepithelial polyps are the most frequently observed mesenchymal tumors of the renal pelvis. We report on one case of fibroepithelial polyp of the renal pelvis with unusual CT findings of totally cystic structure with septations.

    Notes: Abstract Background, aims: The purpose of the present case report was to present 2 ways of treating recession in a periodontal patient combined with regular pocket elimination surgery. The techniques used enabled the operator to reduce the number of surgical sessions and clinically evaluate the 3-year coverage of gingival recessions using a subpedicle connective tissue graft.Methods: Surgery consisted of pocket elimination procedures to treat adult periodontitis as a way to harvest connective tissue to be placed in the areas of recession. The grafted tissue was covered by the primary flap or left uncovered in a pouch, according to 2 different techniques described in the literature.Results: In this case, we observed that, with this approach, we were successful in reducing the number of surgical session as well as achieving objective and subjective goals of therapy in treated areas.

    Notes: Abstract A case of spontaneous thrombosis and infarction leading to death as complications of a cerebral venous malformation in a 13-yearold boy is reported. This is the first published report of this type of complication occurring in a case of venous angioma. While the biologic behavior of cerebral venous malformations has suggested that they are benign in nature, and the results of surgical management have encouraged a conservative approach, the present case illustrates a potential complication and argues against the assumption that these malformations are completely benign in nature.
