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 ...

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...

to define efficacy of pre-operative chemotherapy in down staging of advanced non-round cell soft tissue sarcomas. from sep 2002 to dec 2005, 70 patients were treated by ifosfamid, mesna, cisplatin, adriamycin, mitomycin and subsequent surgery. postoperatively, patients received radiotherapy in cases of microscopically incomplete resection or local recurrence. the median age of the patients was ...

introduction: the effect of severe soft tissue injury on the severity of hemorrhagic shock is still unknown. therefore, the present study was aimed to determine hemodynamic and metabolic changes in traumatic/hemorrhagic shock in an animal model. methods: forty male rats were randomly divided into 4 equal groups including sham, hemorrhagic shock, soft tissue injury, and hemorrhagic shock + soft ...

pachydermodactyly is a rare and benign disease that may be idiopathic, genetic, acquired as a response to repetitive trauma, or associated with several other acquired conditions often pushing the health caregiver to do a bunch of costly lab tests and diagnostic workups to rule out other entities. all health care givers must be aware about this disease for reassure the patients and cut unnecessa...

background: infections include soft tissue infections are notable reason for hospital admission among idus, owing to unsterile injection techniques and equipment, contamination of drugs with organisms, and poor hygiene. in present case report a patient with profound limb infection is introduced. case: a 32 years old man was transferred to the emergency department. he was idu with iranian for 3 ...

BACKGROUND AND OBJECTIVES This report describes the production of a low-cost ultrasound phantom of the lumbosacral spine. The phantom should be a very useful tool to teach the basic skills for ultrasound-guided procedures of the lumbosacral spine. METHODS A lumbosacral spine model is secured to the bottom of a microwave-safe container and is immersed in a concentrated gelatin solution. After ...

This work extends a recently realized inverse problem technique of extracting soft tissue elasticity information via nonrigid model-based image registration. The algorithm uses the elastic properties of the tissue in a biomechanical model to achieve maximal similarity between image data acquired under different states of loading. A new multi-resolution, nonlinear optimization framework has been...

Misregistration due to cardiac motion causes artifacts in two-exposure dual-energy subtraction images, in both the soft-tissue-only image and the bone-only image. Two previous investigations have attempted to avoid misregistration artifacts by using cardiac gating of the first and second exposures. The severity of misregistration was affected by the heart rate, the time interval between the low...

It is well accepted that soft tissue deformation a combination of linear and nonlinear response. During small displacements, tissues deform linearly while during large show deformation. This paper presents new approach for modelling deformation, from the standpoint Mass Spring Method (MSM). The proposed MSM model developed using conical spring methodology which allow to have different stiffness...
