the anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. with the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. immediate implant placement has numerous advantages compared to the delayed procedure including superi...
Abstract The leg is a complex district with functions of weightbearing support, stability, and motility. The management of extensive and complex defects is more challenging and often results in leg amputation or shortening. Leg amputation is a severe mutilation that alters the patient’s work and social life by limiting ambulation and self-sufficiency. During a 3 years period we trea...
OBJECTIVE Intact parathyroid hormone (PTH) assay has recently been reported to be effective in evaluating both 1-84 PTH (whole PTH) and inactive 7-84 PTH. Inactive 7-84 PTH is considered to be increased in hemodialysis patients and to prevent the effects of 1-84 PTH, and intact PTH is considered to overestimate the PTH activity in these patients. As such, a whole PTH assay has recently been dev...
Penetration and estimation of absorbed dose of electron in soft tissue is investigated in this paper. Neck phantom was simulated by MCNPX code version 2.6. The Phantom was included skin, adipose, neck tissue, neck bone and thyroid glands. Radiation source kept near to the skin surface and located in the back of the neck. Electrons were collided perpendicular to the skin surface. The curves show...
BACKGROUND Greater thickness of the tissue extending laterally from the greater trochanter has been associated with a lower risk of hip fracture in women. The effect of trochanteric soft tissue thickness on the risk of incident hip fracture has not been evaluated in men. METHODS We measured trochanteric soft tissue thickness by dual-energy x-ray absorptiometry for all incident hip fracture ca...
Purpose: The development of the novel carbon ion radiotherapy (CIRT) in the treatment of refractory cancers has resulted in the need for a way to accurately evaluate patient prognosis. We evaluated whether L-[methyl-C]methionine (MET) uptake and its change after CIRT were the early survival predictors in patients with unresectable bone and soft tissue sarcomas. Experimental Design: MET positron...
congenital vascular lesions occur most often in children. parents of these children take them to maxillofacial surgeons directly or during the treatment of other complications such as infection or jaw bone disorders. various terms now used are unable to describe the pathogenesis and mechanism of the effect of vascular lesions on growth and development of facial bone. term of hemangioma is used...
introduction: thermal ablation by microwave (mwa) has proven efficacy in treatment of primary and metastatic cancers. soft tissue tumors could be ablated completely using mwa. however, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. case presentation: a 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of tum...
