In the last two decades, the number of phylogenetically informative anatomical characters recognized in the appendicular skeleton of titanosaurian sauropod dinosaurs has increased dramatically with the discovery of new and comparatively complete specimens. Here we provide an overview of the appendicular skeletal morphology of South American titanosaurs and discuss its significance for phylogenetic reconstruction. The appendicular skeletal diversity of South American titanosaurs is substantially greater than was initially appreciated.

Mammary Pagets disease (MPD) is a malignant breast tumor, which is characterized by intraepidermal infiltration from malignant glandular epithelial cells. Often it may include an underlying ductal carcinoma in situ or an invasive ductal carcinoma. Clinically it appears as an erythematous patch, moist or crusted, with or without desquamation that in some cases becomes ulcerated, causing infiltration and inversion of the nipple.

Material And Methods: Twenty emphysematous patients (5 women and 15 men; age range: 55-67 years, mean: 61) candidate for LVRS were submitted to isotope perfusion scanning, chest radiography during maximal inspiration and expiration and Helical CT with the low volume contrast technique, multiplanar reconstructions and density mask.
Results: Only 8 of the 20 patients examined were submitted to LVRS.
