Papel da histomorfometria óssea no diagnóstico diferencial da osteomalacia

Abstract: A osteomalacia é uma doença ósteo-metabólica em que há deficiente mineralização do osso, e é definida pela histomorfometria óssea por apresentar espessura do rebordo osteóide (O.Th) maior do que 15mm, e intervalo de tempo para mineralização (MLT) maior do que 100 dias. As principais etiologias de osteomalacia são a deficiência de ação da vitamina D e a hipofosfatemia. Neste trabalho, 14 pacientes com osteomalacia diagnosticados clínica e laboratorialmente foram divididos em dois grupos: 6 pacientes com deficie… Show more

“… 1 It is typically caused by lack of vitamin D and is characterized by mineralization deficiency of the osteoid matrix in the cortical and trabecular bone, resulting in accumulation of osteoid tissue. 2 Vitamin D deficiency is a pathogenic factor of osteoporosis that can be modified. 5 , 9 The elderly are at particularly high risk for developing osteomalacia, which is frequently misdiagnosed.…”

“…Osteomalacia is a disorder which affects the skeleton; the most frequent cause of osteomalacia is nutritional vitamin D deficiency, and it occurs almost exclusively in the parts of the world where vitamin D insufficiency is endemic [9,6]. It is characterized by mineralization insufficiency of the osteoid matrix in the cortical and trabecular bone, resulting in amassing of osteoid tissue [18]. Factors that increase the exposure of the skin to sunlight and also the addition of dietary sources of vitamin D can contribute to the absence of skeletal mani festations of absence [26,12].…”

“…Por meio da microscopia de luz é possível descrever e quantificar o processo de formação e reabsorção óssea (CORRÊA et al, 2000). A histomorfometria, em diferentes métodos de processamento e análises, é uma técnica aceita e bastante utilizada para avaliar diversos biomateriais em diferentes espécies (REIS et al, 2010;SELIM, 2012;MARCONDES, 2014;NÓBREGA, 2014).…”
