extra renal extra cranial malignant rhobdoid tumors (mrt) are rare, frequently lethal and affect mostly children. no definite treatment has been made and the role of radiation therapy is poorly defined. this report explains a 14 year old girl with mrt in her neck soft tissue. she is alive with no evidence of disease 18 months after diagnosis. through the experience with this case, we suggested ...

granular cell tumor (gct) was first described by abrikossoff in 1926. gct is a rarely seen soft tissue tumor and is generally benign. while the tumor can be seen in all parts of the body it is generally located on the head and neck region, and especially on the tongue. gct is rarely seen in the anal-perianal region. in accordance with literature this case was reported because it was thought to ...

introduction:different types of prosthesis are available for stapes replacement. because there has been no published report on the efficacy of the titanium soft-clip vs the fluoroplastic causse loop teflon piston, we compared short-term hearing results of both types of prosthesis in patients who underwent stapedotomy due to otosclerosis.materials and methods:a total of 57 ears were included in ...

lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. some studies show that less than 1% of lipomas were ossified. we describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. to the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and h...

nowadays, robots account for most part of our lives in such a way that it is impossible for usto do many of affairs without them. increasingly, the application of robots is developing fastand their functions become more sensitive and complex. one of the important requirements ofrobot use is a reliable software operation. for enhancement of reliability, it is a necessity todesign the fault toler...

according to the iranian code of practice for seismic resistant design of buildings, soft storey phenomenon happens in a storey when the lateral stiffness of the storey is lower than 70% of the stiffness of the upper storey, or if it is lower than 80% of the average stiffness of the three upper stories. in the combined structural systems containing moment frames and shear walls, it is possible ...

the management of soft tissue defects in tibial fractures is essential for limb preservation. current techniques are not without complications and may lead to poor functional outcomes. a salvage method is described using three illustrative cases whereby a combination of flaps and antibiotic-impregnated polymethylmethacrylate beads are employed to fill the bony defect, fight the infection, and p...

Abstract The field of biometrics research encompasses the need to associate an identity individual based on persons physiological or behaviour traits. While use intrusive techniques such as retina scans and finger print identification has resulted in highly accurate systems, scalability systems real-world applications surveillance border security been limited. As a branch research, origin soft ...
