Osteosarcoma is the most common type of bone cancer that involves adolescents and young people. Amputation is usually proposed by some surgeons after diagnosis which is not acceptable for the patients. In this article, the results of limb-salvage procedures for patients with high-grade malignant osteosarcoma were investigated. The survival rate, functionality of limb, and complication...

Background: Limb salvaging surgeries are current surgical treatment of extremity bone sarcomas. Resected bonereplacement consists of two main methods; tumor prosthesis versus structural allograft. Biological reconstruction withan allograft is an economic cheap method in young sarcoma patients, however, the surgeons are more convinced withtumor prosthesis replacement.Methods: We evaluated the sh...

Bovine pericardium is used for heart valve leaflet replacement where the strength and thinness are critical properties. Pericardium from neonatal animals (4-7 days old) is advantageously thinner and is considered as an alternative to that from adult animals. Here, the structures of adult and neonatal bovine pericardium tissues fixed with glutaraldehyde are characterized by synchrotron-based sma...

congenital defects of the pericardium are considered rare. until 1979 , the reported cases were only about 200.1 total absence of the left pericardium is the most common defect2 and less common is a partial defect of the left pericardium. other types, i.e. isolated right-sided defects, total pericardial absence and diaphragmatic pericardial defects are very rare.3 before the last decade, the di...

from the University of Alberta (Canada) report a series of animal experiments designed to test the mythic role of gluteraldehyde in preventing recognition of bioprosthetic heart valve antigenicity with subsequent rejection and failure. Gluteraldehyde–cross-linked xenograft tissues (initially porcine) have been used in the manufacturing of stented (and now stentless) heart valves since 1970. Ori...

This may be distinguished from intrapericardial bands if the parietal pericardium is thin and fixed, because most of the pericardial bands in our patients had an undulating motion during the cardiac cycle. Awareness of the pericardial abnormalities described here may allow correlation with specific pathologic findings by investigators in the future.9 For the present, these findings may improve ...

Tunicates, small invertebrates within the phylum Chordata, possess a robust tubular heart which pumps blood through their open circulatory systems without the use of valves. This heart consists of two major components: the tubular myocardium, a flexible layer of myocardial cells that actively contracts to drive fluid down the length of the tube; and the pericardium, a stiff, outer layer of cell...

discussion hydatid cyst in pericardium represents only 0.5-2% of cases of systemic echinoccocal infection. isolated pericardial cyst is very rare in endemic region and may present mimicking acute coronary syndrome. cardiac hydatid cysts should always be considered in presence of eosinophilia as present like acute coronary syndrome in endemic area. introduction hydatid cysts are most commonly fo...
