[Estimate of osteoporosis fracture risk with ultrasound bone assessment].

BACKGROUND: Multiple studies suggest that ultrasound measurement of the bone can be a rapid, cheap, and radiation-free alternative to determine the fracture risk. In this paper the ultrasound measurement of the bone was performed among 288 postmenopausal women, and the influence of gynecologic history and factors related to lifestyle on the obtained values was examined. PATIENTS AND METHODS: One hundred nineteen healthy postmenopausal women and 169 women with previous osteoporotic fractures were included in the study. Both weight and height were determined and a clinical questionnaire was administered to assess factors related to bone mineral density. The values of broadband ultrasound attenuation (BUA) and speed of sound (SOS) were obtained with a contact ultrasound analyzer. RESULTS: Among women without fractures the mean BUA and SOS values (64.1 [14.9] and 1,601.1 [34.5], respectively) were significantly higher than mean BUA (48.8 [17.3]) and SOS (1,573 [57.8]) values among women with fractures (p < 0.001). Using the logistic regression analysis for predicting fracture risk, the model that suited best was that including BUA (OR = 0.668 [0.544-0.818]), age (OR = 1.102 [1.055-1.151]), age at postmenopause (OR = 0.794 [0.731-0.862]) and height (OR = 0.932 [0.883-0.983]). The area under the curve for this model was 0.871. CONCLUSIONS: BUA and SOS values are lower among women with osteoporotic fractures. The fracture risk can be predicted by means of a model including the variables BUA, age, postmenopausal age, and height.

[Bone ultrasound in healthy women and bone mass related factors].

BACKGROUND: Bone mineral density (BMD) has been related with age, hormonal status, body mass index (BMI) and life style. We have evaluated the influence of these factors on BMD in healthy women, without risk factors for osteoporosis, using ultrasound measures. PATIENTS AND METHODS: We have selected 255 women (136 premenopausal and 119 postmenopausal). We measured the weight and height. Other factors related to BMD were assessed with a clinical questionnaire. With an ultrasonic bone contact analyser broadband ultrasonic attenuation (BUA) and speed of sound (VS) were obtained. RESULTS: Premenopausal women had mean (SD) BUA and VS values (73.4 [13.1] and 1,617.2 [30.4], respectively) significantly higher than postmenopausal women (BDA 64.1 [14.9] and VS 1,601.1 [34.5]; p < 0.001). No relationship between BUA, VS and the style of life related variables was found. Age and weight were significant predictors of BUA in all women in multiple regression model, and the length of lactation in premenopausal women. The association of BUA with age were significantly stronger (p < 0.05) in postmenopausal women. CONCLUSIONS: Age and body weight were the factors more strongly associated with ultrasonic measures in healthy women. The effect of age was different depending on menopausal status. No relation has been found between life habits and bone mass.

Poland-Moebius syndrome in a boy and Poland syndrome in his mother.

A 4 4/12-year-old boy with the Poland-Moebius syndrome, whose mother had the POland syndrome, is presented. This is the first report of the occurrence of both syndromes in the same family, suggesting that they are expressions of the same autosomal dominant gene.

[Antiphospholipid antibodies in systemic lupus erythematosus: incidence, significance and relation to lupus nephritis].

The prevalence of three different types of antiphospholipid antibody in 88 consecutive patients with systemic lupus were 27.2% for lupus anticoagulant (LAC), 31.8% for anticardiolipin antibody (aCL), and 13.6% for falsely positive serologic tests for syphilis (FPSTS). The three tests were correlated, thus confirming the overlapping specificities of this family of antibodies. Although FPSTS was not associated with any particular manifestation of systemic lupus, aCL correlated with thrombosis (p = 0.0001), thrombopenia (p = 0.009), neuropsychiatric features (p = 0.02) and membranous nephropathy (p = 0.001), while LAC correlated with thrombosis (p = 0.001) and hemolytic anemia (p = 0.04). The previously unreported association between membranous nephropathy and aCL might explain some features of the former, particularly the higher incidence of thromboembolic complications and the poorly known relation with renal vein thrombosis.
