INTRODUCTION There is little evidence regarding the effects of dairy product intake on bone mineralization among late adolescents, especially in Asians. The aim of this study was to determine the association between dairy product intake and bone strength as measured by quantitative ultrasound (QUS) in a large Japanese population. METHODS Subjects were 38,719 high school students (14,996 males...

The ultimate goal of quantitative ultrasound (QUS) imaging methods based on backscatter coefficient (BSC) estimates is to obtain system-independent structural information about samples. In the current study, three BSC estimation methods were compared and evaluated using the same backscattered pressure datasets in order to assess their consistency. BSC estimates were obtained from two phantoms w...

OBJECTIVE To measure the reference young adult mean values in healthy women of the centre of Italy by Quantitative heel UltraSound (QUS). METHODS The study group was composed by 70 caucasian women: mean age was 25.4 years (Standard Deviation 4.7), mean weight was 58 Kg (SD 8.2), mean height was 166 cm (SD 5.8), mean BMI was 20.9 kg/m 2 (SD 2.5). Every subject was evaluated firstly with an ori...

OBJECTIVES With the growing demand for bone densitometry services there is a need for simple, cost-effective and ideally mobile devices which can identify individuals who are at risk of osteoporotic fracture. When new devices are evaluated, it is useful to examine the correlation with the established 'gold standard' technique of dual x-ray absorptiometry (DXA). This study examined the correlati...

BACKGROUND Inuit women are highly exposed through their traditional seafood based diet to organochlorine compounds, some of them displaying endocrine disrupting properties. We hypothesized that this exposure might be related to bone characteristics that are altered in osteoporosis, because hormone deficiency is a known risk factor for the disease. METHODS We measured quantitative ultrasound p...

The skeletal response to short-term exercise training remains poorly described. We thus studied the lower limb skeletal response of 723 Caucasian male army recruits to a 12-wk training regime. Femoral bone volume was assessed using magnetic resonance imaging, bone ultrastructure by quantitative ultrasound (QUS), and bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) of the ...

osteoid osteomata are rarely found in the distal phalanges of the hand. the usual presenting features are chronic pain, nail enlargement and increase in size of the terminal part of the digit. diagnosis is difficult but surgical excision is effective for treating the patients’pain. we reported this tumor in distal phalanx of the middle finger.

Ungual cartilage ossification in the forelimb is a common finding in horses. Subtle abnormalities associated with the ungual cartilages can be difficult to identify on radiographs. Magnetic resonance (MR) imaging findings of 22 horses (23 forelimbs) with a fracture of the distal phalanx and ossified ungual cartilage were characterized and graded. All horses had a forelimb fracture. Eleven invol...

ABSTRACT Ritscher-Schinzel Syndrome (RSS) is a clinically variable, autosomal recessive disorder, involving cardiac, cerebellar and craniofacial abnormalities. Numerous reports describe hand changes in RSS patients; however, a detailed characterization of the hands has not previously been performed. OBJECTIVE The purpose of this study was to identify whether specific radiographic hand changes...

Three fractures at the base of the terminal phalanx of the finger and one at the base of the terminal phalanx of the tow were initially misdiagnosed as paronychias. If a 'paronychia' follows trauma, the possibility of a fracture should be considered and radiographs taken of the digit.
