extramedullary plasmacytoma (emp) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.we describe multiple primary emp in a 37 year old man, without involvement of bone or bone marrow. emp usually has a good ...

background in stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. objectives to determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (fast) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. patients and methods we performed a prospective obs...

multiple sclerosis (ms) is a chronic inflammatory disease of the central nervous system characterized by widespread inflammation, focal demyelination and a variable degree of axonal and neuronal loss. ionic conductances regulate t cell activation as well as neuronal function and thus have been found to play a crucial role in ms pathogenesis. since present therapeutical approaches are only parti...

multiple sclerosis is an autoimmune cns-disease characterized by inflammatory neurodegenerative events occurring with de- and remyelination. recent evidence show that demyelinated neurons are less excitable than myelinated ones while at early stages of remyelination these neurons seem to be hyperexcitable. the latter is a transitory condition that, very likely, leads to impaired neuronal networ...

background: there have  been  several studies  done  on the role of metals in the occurrence  of multiple sclerosis (ms) disease, but their roles have not been confirmed yet. because of the lack of information on this issue, this study compared  the  serum  level  of  copper and zinc in ms patients with their levels in a control group. methods: this  was  an  analytical,  cross-sectional  study...

multiple  sclerosis  (ms) is  an  autoimmune  multifactorial  degenerative  disease  with detrimental affliction on central nervous system. mhc class i chain- related genea,b(mica and micb) are nonclassical human leukocyte antigens that can affect on some diseases and also on transplantation. the purpose of this study was to evaluate the mica and micb mrna expression in multiple sclerosis patie...

multiple sclerosis (ms) is an inflammatory disorder, in which neurons in central nervous system (cns) become demyelinated .ms is named for its formation of plaques due to sclerosis of myelin. variable degree of demyelination results in mild, mediate or severe symptomatic episodes of this disease. it is commonly characterized by recurrent relapses and often followed by severe neurological disabi...

patients and methods in this study, a total of 92 patients with relapsing-remitting multiple sclerosis (rrms) were randomly allocated into three equal groups; each treatment group received one of the foregoing drugs (cinnovexr, rebif and betaferon) for one year. at the beginning and end of the study, patients ‘ edss was measured and compared. results in this study, the relative frequency of fem...
