OBJECTIVE Atherosclerotic plaque development in the arterial wall is the result of complex interaction between the wall's endothelial layer and blood hemodynamics. However, the interaction between hemodynamic parameters and inflammation in plaque evolution is not yet fully understood. The aim of the present study was to investigate the relation between wall shear stress (WSS) and vessel wall in...
Using a direct immunofluorescent method, histological locations of immunoglobulins (IgG, IgM, IgA and IgD of heavy chain, and kappa and lambda of light chain) and complement components (C3 and C4) were studied in 78 brain tumors, which included 24 astrocytomas, 6 metastatic tumors, 5 medulloblastomas, 4 malignant lymphomas, 15 meningiomas, 8 schwannomas, 8 pituitary adenomas, and 8 other miscel...
The value of ultrasonography and UGAB for diagnosing chest wall tumors was investigated in 21 patients of whom 13 had metastatic and eight benign disease. Chest wall tumor showed a hypoechoic mass with tapered edges. The margin between the tumor and lung was curved and smooth in all cases. Movement of the tumor during breathing was synchronized with that of the chest wall. We believe that the u...
The diagnosis of astroblastoma is based on a typical histological aspect with perivascular distribution of cells sending cytoplasmic extensions to the vessels and vascular hyalinization. These criteria are useful for standardizing the identification of the tumor, but, in spite of this, there are discrepancies in the literature concerning the age distribution and the benign or malignant nature o...
Four cases of desmiod tumors of the anterior abdominal wall recently treated at the University of Chicago Hospitals and Clinics are presented. From our experience we conclude: 1. Inadequate excision of desmoid tumors results in local recurrence. 2. Adequate excision of desmoid tumors ot the abdominal wall sometimes necessitates creation of an abdominal wall defect too large for primary closure....
