Cross-sectional observations of thyroid function in geriatric Mexican outpatients with and without dementia.

Unlabelled: This work was aimed at determining and comparing the frequency of abnormal levels of thyroid stimulating hormone (TSH) in geriatric outpatients with and without dementia. This cross-sectional study enrolled patients, aged 60 years and older with or without dementia (established on the basis of DSM-IV-R), from geriatric outpatient unit with third level of medical care. Comparisons were between 33 (34%) patients without dementia versus 26 (58%) with dementia; both among 142 (24%) randomly selected sample (RSS) from unit's register; and the 101 (89%) in the memory-clinic case series (MCCS) of dementia were contrasted with the former.

Vitamin D receptor polymorphisms and bone mineral density in Mexican women without osteoporosis.

Polymorphisms corresponding to Apa I, Bsm I, and Taq I restriction endonucleases at the vitamin D receptor (VDR) gene and bone mineral density (BMD) at lumbar spine (L2-L4) and proximal femur (neck, Ward's triangle and trochanteric region) sites were examined in a sample of 98 Mexican women (age 55 +/- 10 years). None of the subjects were pregnant or nursing and none had a previous diagnosis of osteoporosis. Polymorphisms were assessed by the restriction fragment length polymorphism - polymerase chain reaction (RFLP-PCR) technique.

Risk factors of breast cancer in Mexican women.

Objective: To investigate the association between family history (FH) of neoplasia, gyneco-obstetric factors and breast cancer (BC) in a case-control study. In cases, to analyze those variables in relation with early onset of BC, the manner of detection (self-examination, prompted by pain, or casual), the size of tumor, and the elapsed time to seek medical attention.

Material And Methods: Data from 151 prevalent BC cases and 235 age-matched controls were analyzed by multiple logistic regression, to assess the influence of BC risk factors.
