Fibrous dysplasia (FD) is a disease caused by postzygotic activating mutations of GNAS (R201C and R201H) that encode the α-subunit of the Gs stimulatory protein. FD is characterized by the development of areas of abnormal fibroosseous tissue in the bones, resulting in skeletal deformities, fractures, and pain. Despite the well-defined genetic alterations underlying FD, whether GNAS activation i...
مقدمه: مطالعات زیادی نشان می دهند مرفین در دوز mg/kg10 اثر بی دردی و ضد التهابی و در دوز ?g/kg 1 اثر پر دردی و تشدید التهاب از خود نشان می دهد. علاوه بر این وجود گیرنده های اوپیوئیدی بر روی فیبرهای آوران اولیه و به ویژه فیبرهای c ثابت شده است. با توجه به نقش فیبرهای c در انتقال محرکهای آسیب رسان و وجود گیرنده های اوپیوئیدی ? روی این فیبرها ، مطالعه حاضر ، نقش فیبرهای c در اثرات بی دردی(analgesi...

background: the optimal strategy in percutaneous coronary intervention (pci) for coronary artery bifurcation lesions has yet to be agreed upon. we compared a strategy for stenting the main vessel to provide a complete perfusion flow in the side branch, namely thrombolysis in myocardial infarction (timi) - iii, with a strategy for intervention in both the main vessel and the side branch (mv + sb...
the histopathologic diagnosis of orbital and ocular adnexal lymphoproliferative lesions is difficult, resulting controversy in classification, determining benignity or malignancy of them and treatment modality selection. we designed the following study to evaluate clinical, histopathologic and if necessary immunochemical features of them in decreasing indeterminate cases. the study includes 51 ...
introduction: striae distensae (sd) are a frequent skin condition for which treatment remains a challenge. the 1540-nm non-ablative fractional laser (star lux 500) has been shown to improve atrophic scars by increasing the amount of dermal collagen. to assess the safety and efficacy of the star lux 500 laser in the treatment of mature hypopigmented striae in persian people (striae alba). method...
this case is a 19-year-old soldier who suffered a combined elbow dislocation and posterior monteggia fracture and dislocation (type ii). the ulna fracture was managed by orif. the elbow dislocation was managed by closed reduction and immobilization in 900 flexion. the posteriorly dislocated radial head was kept reduced by a transarticular pin. after 6 months elbow and forearm motion was restric...
Aim. Cemento-osseous dysplasia (COD) represents a rare group of benign fibroosseous disorders, while osteogenic sarcoma (OS) on the hand, is a malignant tumour of ominous prognosis. A combination of COD and OS is rare and sparsely reported in literature. There are only four reported cases known to the authors. The aim of this paper is to report additional cases of COD occurring concurrently wit...
tumefactive fibroinflammatory lesions (tfls) are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. tfls are seen more frequently in males between 10 and 74 years of age. the usual site of involvement is the head and neck region, but rarely the extremities may be involved. coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosi...
