Purpose: The purpose of the research was to study the relationship between menopausal status and bone structure during the menopausal transition. Methods: A random sample of 1932 Hungarian women was enrolled in the study. Bone mass was estimated by the Drinkwater-Ross method. Bone structure parameters were assessed by a quantitative ultrasound (QUS) device. High and very high risk of osteoporos...

BACKGROUND The extent of reversibility of loss of bone mass density (BMD) in hyperthyroid patients after treatment is not clear. METHODS The bone density measured by dual X-ray absorptiometry (DXA), the parameters of quantitative ultrasound (QUS) and biochemical markers of bone turnover of 22 patients were measured before and after one year of treatment with thiamazole and levothyroxine. RE...

Aim. To validate a radial quantitative ultrasound (QUS) system with dual energy X-ray absorptiometry (DXA), a criterion technique in bone status assessment among children. Methods. Bone health was evaluated using a radial QUS system (Sunlight Omnisense 8000P) to measure the speed of sound (SOS) at one-third distal radius of the nondominant hand and DXA (Hologic QDR) was used to assess whole bod...

A longitudinal study was conducted to investigate the relation between a polymorphism in the vitamin D receptor (VDR) gene and changes in bone mineral density (BMD) and quantitative ultrasound of the phalanges (QUS) over a five-year period. The subjects were 456 postmenopausal women with osteoporosis undergoing treatment, aged 59.95±7.97 years (mean±standard deviation [SD]) at baseline. BMD was...

Aim. To provide bone status assessment in infancy using quantitative ultrasound (QUS) applied to second metacarpus. Methods. 103 healthy term infants and 3 patients with rickets, aged ≤ 12 months, underwent metacarpal QUS evaluation using QUS DBM Sonic Aurora IGEA (MO, Italy), which measures speed of sound (mcSOS) and bone transmission time (mcBTT). Results. In the total sample, median (interqu...

PURPOSE/INTRODUCTION The present study investigates potential associations between liquid chromatography-mass spectrometry (LC-MS) measured sex hormones, dehydroepiandrosterone sulphate, sex hormone-binding globulin (SHBG) and bone ultrasound parameters at the heel in men and women from the general population. METHODS Data from 502 women and 425 men from the population-based Study of Health i...

Quantitative ultrasound (QUS) is a novel imaging technique that is hypothesized to be capable of monitoring of High Intensity Focused Ultrasound (HIFU) treatment by quantifying tissue changes during exposure. Experiments were conducted on fresh liver samples from rats and lesions were formed using a HIFU system (1-MHz, f/1.2). A wire thermocouple was inserted into the sample to monitor temperat...

OBJECTIVE The purpose of this study was to investigate the association between an AluI RFLP of the calcitonin receptor (CTR) gene and quantitative ultrasound (QUS) parameters in Korean men, and the interaction with nutrition as a lifestyle factor. MATERIALS AND METHODS Broadband ultrasound attenuation, speed of sound and stiffness index of the calcaneus were measured using an ultrasound bone ...

The bone is one of the relevant target organs of heavy metals, and heavy metal toxicity is associated with several degenerative processes, such osteoporosis and bone mineral alterations, that could lead to fractures. We aimed to study a presumed relationship between bone density, evaluated by quantitative bone ultrasound (QUS), dual-energy X-ray absorptiometry (DXA) and peripheral quantitative ...
