Osteogénesis imperfecta corrección de Varo con Osteotomías en paciente adulto reporte de un caso
Osteogenesis imperfecta varus correction in adult patient: case report

Cambios rev. méd; 15 (1), 2016
Introducción: La osteogénesis imperfecta (OI) es una enfermedad genética, que se caracteriza por la alteración de la formación de colágeno tipo 1 (COL1A1 Y COL1A2), que causa fragilidad, ósea y dentaria. Según el grado de afectación el Dr. Sillence en 1979 la clasificó en cuatro tipos; el Dr. G...

Guías para el diagnóstico, la prevención y el tratamiento de la osteoporosis inducida por glucocorticoides en el adulto
Guidelines for the diagnosis, prevention and treatment of glucocorticoid-induced osteoporosis in adults

Actual. osteol; 12 (2), 2016
La osteoporosis inducida por glucocorticoides (OIC) es la causa más común de osteoporosis secundaria. La pérdida ósea se produce en forma temprana, en los primeros meses siguientes a la introducción de los glucocorticoides (GC), dependiendo de la dosis diaria. La patogénesis es multifactorial y el ...

Using agents that suppress bone remodeling to treat or prevent joint disease: quo vadis?

Actual. osteol; 12 (3), 2016
Treatment of osteoarthritis (OA) with antiremodeling agents has had a mixed record of results. It is likely that remodeling suppression is only effective when used in the early phases of OA, before significant progression. Animal and human studies largely bear this out. Treatment of young mice with a RAN...

Response of a co-culture model of epithelial cells and gingival fibroblasts to zoledronic acid

Braz. oral res. (Online); 30 (1), 2016
Abstract Osteonecrosis of the jaw is an adverse effect of bisphosphonates. While the etiopathogenesis of this condition has been investigated, the interactions and effects of bisphosphonates on oral mucosa cells remain unclear. It is hypothesized that cell culture models, such as co-culture or three-dime...

β-ARRESTIN/CONNEXIN 43 (Cx43) complex anchors ERKS outside the nucleus: a prerequisite for bisphosphonate antiapoptotic effect mediated by Cx43/ERK in osteocytes

Actual. osteol; 12 (1), 2016
Bisphosphonates (BPs) anti-fracture efficacy may be due in part to inhibition of osteocyte apoptosis. This effect requires opening of connexin (Cx) 43 hemichannels and phosphorylation of the extracellular signal regulated kinases (ERKs). However, unlike ERK activation by other stimuli, the Cx43/ERK pathw...

Raloxifene neutralizes bone brittleness induced by anti-remodeling treatment and increases fatigue life through non-cell mediated mechanisms

Actual. osteol; 12 (3), 2016
Pre-clinical data have shown that tissue level effects stemming from bisphosphonateinduced suppression of bone remodeling can result in bone that is stronger yet more brittle. Raloxifene has been shown to reduce bone brittleness through non-cellular mechanisms. The goal of this work was to test the hypot...

Efeitos da terapia combinada com ácido zoledrônico e propranolol na resistência mecânica em um modelo de rato com osteoporose por desuso

Rev. bras. reumatol; 55 (6), 2015
Resumo Objetivos: Investigar os efeitos aditivos do agente antirreabsorção ácido zoledrônico (ZOL), isolado e em combinação ao propranolol (PRO), em um modelo de rato com osteoporose por desuso. Métodos: Usou-se um modelo de pata traseira direita de rato privada de descarga de peso para estudar as...

Hipercalcemia grave como forma de apresentação de leucemia linfoblástica aguda em crianças

RESUMO A hipercalcemia é um distúrbio metabólico raro em pediatria, potencialmente fatal, apresentando um vasto diagnóstico diferencial, incluindo neoplasias. Relatamos aqui o caso de uma criança de 3 anos, previamente saudável, admitida no serviço de urgência por fadiga, hiporreatividade, febre ...

Sinusitis maxilar por osteonecrosis asociada a bisfosfonatos en pacientes con cáncer de mama: serie de casos

Los bisfosfonatos (BF) son fármacos ampliamente utilizados como estabilizadores óseos en el tratamiento de metástasis óseas, osteoporosis, enfermedad de Paget, entre otras patologías, debido a sus efectos anti-tumorales y a la característica de inhibir la actividad osteoclástica. La osteonecrosis ...
