[Comparative evaluation of bone mineral density in Mexican women using x-ray bone densitometry and ultrasound]. / Evaluación comparativa de la densidad mineral ósea en mujeres mexicanas entre el osteodensitómetro de rayos X y de ultrasonido.

With lifestyle changes in women, smoking and use of beverages with caffeine, and sedentarism increasing, so the risk factors for decalcification, increase; which is a public health problem by the higher incidence of osteoporotic fractures, as the age advances, specially in the postmenopause woman, which means a greater secondary morbidity-mortality; an important cause of physical disability, which directly affects psychoemotional wellbeing in women. In this study two methods of bone densitometry, were used; one of x ray, and other with ultrasound in 138 women during postmenopause with an average index of corporal mass of 29. Both results were compared of bone density, T measurement with osteopenia and osteoporosis. Double densitometry, was done in the 138 patients of lumbar spine with DEXA equipment, and of calcaneum with DTU-one equipment, by the same technician, finding the difference of T punctuation in this double study.

[Comparative study between estradiol valerate combined with cyproterone acetate, and conjugated equine estrogens combined with medroxyprogesterone acetate as hormone replacement therapy in climacteric]. / Estudio comparativo entre la combinación valerianato de estradiol-acetato de ciproterona y estrógenos conjugados equinos-acetato de medroxiprogesterona como terapia hormonal de reemplazo en el climaterio.

OBJECTIVE: To compare the effectiveness in the control of climacteric symptoms, the tolerability and the uterine bleeding pattern between two types of hormone replacement therapy. MATERIAL AND METHODS: 81 postmenopausal women between 40 and 60 years age with vasomotor symptoms were studied. Randomly it was administered: I. Conjugated equine estrogens (CEE)-Medroxyprogesterone acetate (MPA): 21 tablets with 0.625 mg of CEE and 10 tablets with 5 mg of MPA which were taken with the last ten tablets of CEE in each cycle (n = 3 7). II. E2V-CPA: 11 tablets with 2 mg of E2V and 10 tablets with 2 mg of E2V and 1 mg of CPA (n = 44). Each cycle comprised 28 days. The treatments were compared with squared Chi and Mann-Whitney U test. RESULTS: The hot flushes presence was significantly greater in the group with CEE-MPA (p < 0.03). Severe throbs at the end of the study had a trend to be more frequent in the group with EC-MPA (p < 0.06). At the end of the study there was a greater frequency of breast tenderness in the group with CEE-MPA (P = 0.009). CONCLUSIONS: Both treatments have good effectiveness, tolerability and same bleeding pattern. Only the frequency of hot flushes, the presence of severe throbs and breast tenderness were lower in the group with E2V-CPA, that makes this preparation an option that can have a better acceptance by the women.
