osteoporosis (op) is a frequent complication of rheumatoid arthritis (ra) and longitudinal studies have documented increased rate of bone loss in ra patients. to determine the frequency of low bone mass as well as the influence of disease duration and corticosteroid use on bone mass in patients with ra, 88 patients with ra and 112 age matched controls were studied. bone densitometry was perform...

introduction: gold standard for alveolar cleft bone grafting is autogenous bone. advantage of adding the growth factors to the bone is established, so adding prf to the autogenous bone may have beneficial effects. methods:  platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. results:  autogenous bone in all (four cases) was...

Background: Osteoporosis is one of the uncomfortable postmenopausal symptoms. The risk of imbalanced nutrition especially traces elements and vitamins are high during post menopause and may lead to osteoporosis due to reduction of content of mineral bone. The aim of this study was to investigate the potential consequence of Selenium (Se) treatment in ovariectomized rat model with osteoporosis i...

Malakoplakia is a rare inflammatory disorder that affects predominantly the urinary tract and kidneys. Isolated renal parenchymal involvement occurs in 16% of all cases [1]. Urinary tract and digestive malakoplakia have been reported in transplant recipients but involvement in transplant tissue is rare. We report a case of renal allograft parenchymal malakoplakia and present a brief review of k...

INTRODUCTION Malakoplakia is an unusual and very rare chronic inflammatory disease. In bladder especially it can mimic malignancy and lead to serious misdiagnosis. CASE REPORT We presented a case of a middle-aged woman with persistent macrohematuria and cystoscopically polypoid bladder mass that resembled a neoplastic process. The final diagnosis was based on cystoscopic biopsy and microscopi...

Malakoplakia is an uncommon chronic inflammatory disorder, which is characterized by the presence of histiocytes containing concentric concretions known as Michaelis-Gutmann bodies in a background of mixed inflammation. The urinary tract is the most commonly involved site. However, malakoplakia can be found in a wide range of other organs throughout the body. Its occurrence has been attributed ...

Objectives: An efficient, safe, affordable and easily accessible measuring instrument for quantitative assessment of bone prior to dental implant placement enables more accurate treatment planning. Costly imaging modalities are neither widely available, nor affordable for some patients. This study sought to assess the efficacy of a newly designed digital bone gauge for measurement of bone width...

Background: Bone tissue engineering requires materials that are biocompatible, mechanically suited for bone function, integrated with the host skeleton, and support osteoinduction of the implanted cells for new bone formation. The aim of this study was to compare the osteogenic potential of xenograft with hydroxyapatite/β- tricalcium phosphate (HA/β-TCP) scaffold. Methods: New Zealand rabbits (...

statement of problem: placement of mini-dental implants when single-tooth restorations are needed and the space is not sufficient to insert a standard diameter implant is indicated. there are many different mini-implant brands with various materials and surface characteristics; however, there are just few studies comparing them with each other. objectives: in this study, finite element analysis...
