Correlation between ultrasound velocity and densitometry in fresh and demineralized cortical bone

Clinics; 71 (11), 2016
OBJECTIVE: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals. METHODS: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were first measured. The bone segments were then divided ...

Low-level laser therapy associated to a resistance training protocol on bone tissue in diabetic rats

ABSTRACT Objective The present study aimed to evaluate the in vivo response of a resistance training and low-level laser therapy (LLLT) on tibias and femurs of rats with diabetes mellitus (DM). Materials and methods Forty male Wistar rats were randomly distributed into four experimental groups: contr...

Estudo biomecânico comparativo da resistência de segmentos ósseos de rádios de cães autoclavados ou desvitalizados em nitrogênio líquido

O presente estudo comparou, por meio do ensaio de flexão em quatro pontos, a resistência de segmentos de rádios de cães autoclavados e desvitalizados em nitrogênio líquido. Avaliaram-se 40 rádios, que foram divididos em quatro grupos: grupo autoclave (GA), grupo controle autoclave (GCA), grupo nit...

Effects of chronic mild stress on parameters of bone assessment in adult male and female rats

Pesqui. vet. bras; 36 (supl.1), 2016
Osteoporosis is a multifactorial disease of high prevalence and has great impact on quality of life, because the effects on bone structure increase the risk of fractures, what may be very debilitating. Based on the observation that patients with depression have lower bone mineral density than healthy ind...

Asymptomatic vertebral fractures in patients with low bone mineral density

Summary Objective: Vertebral fracture assessment (VFA) is a test technique that can be used to detect asymptomatic vertebral fractures (AVF). It uses dual energy X-ray bsorptiometry (DXA) and can be performed concurrently with bone densitometry. This study aims to assess the prevalence of AVF in patient...

Compromiso óseo en mastocitosis sistémica: una asociación frecuente, pero muchas veces inadvertida

Rev. méd. Chile; 144 (3), 2016
Systemic mastocytosis (SM) is characterized by pathologic expansion and activation of mast cells. The main clinical manifestations of SM include skin involvement, gastrointestinal symptoms and anaphylaxis due to the release of its mediators. Thirty percent of pat ients with SM have a low bone mass and 20...

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 ...

Prevalencia de osteoporosis: discrepancia de acuerdo a las áreas esqueléticas de medición
Prevalence of osteoporosis: discrepancy according to the skeletal areas of evaluation

Actual. osteol; 12 (3), 2016
Existe discrepancia en la elección de las áreas esqueléticas a evaluar para determinar la prevalencia de osteoporosis (OP). La International Society for Clinical Densitometry sugiere evaluar la columna lumbar (CL) y el fémur proximal (FT), mientras que la International Osteoporosis Foundation (IOF) s...

Utilidad del tratamiento secuencial con teriparatide y denosumab en la osteoporosis de alto riesgo: nuestra experiencia asistencial
Benefits of sequential treatment of high risk osteoporosis with teripartide and denosumab: our experience

Actual. osteol; 12 (1), 2016
El tratamiento de las formas graves de osteoporosis representa un desafío en la práctica asistencial. Reportamos tres pacientes con formas graves de osteoporosis tratadas en el Instituto de Diagnóstico e Investigaciones Metabólicas con un esquema secuencial de teriparatide 20 μg/día durante 18 mese...
