AimS: Vitamin D is known to be vital in sustaining musculoskeletal functions, with its deficiency may cause muscle weakness and decreased bone mineral density. Vitamin D inadequacy is highly prevalent and its deficiency or insufficiency estimated to affect one billion people worldwide. It causes secondary hyperparathyroidism, bone loss, fractures and it has been associated with a number of other conditions, such as impaired muscle function (1), we decided to verify if there is an association between 25(OH)D status and handgrip strength and with lean muscle mass after cholecalciferol supplementation in elderly women.Methods : We studied fifty-four postmenopausal women with serum 25(OH)D below 30 ng/mL during three months. Cholecalciferol supplementation was divided into two levels according to classification: deficient (10000 units/day) and insufficient (2000 units/day). Changes in biochemical response and in body composition were assessed using dual-x-ray energy absormetry, handgrip strength and blood tests before and after supplementation.Results: The majority of the sample were vitamin D deficient. There was no difference in the deficient group for handgrip strength after the supplementation (p=0,489), but PTH had a statistically significant reduction (p=0.001). Besides, the deficient group had a decrease in lean mass even after the intervention (p=0.006). The results were similar when comparing within results of the insufficient group, however lean mass remained stable (p=0.423).Conclusion: Three-month cholecalciferol supplementation alone in elderly women with doses according to 25(OH)D serum was insufficient to change handgrip strength and total lean muscle mass, however secondary hyperparathyroidism was corrected.

Aims: To commemorate the centennial of the geriatrics, the authors present a review of the population aging, the elderly individual, the characteristics of the geriatric medicine, and its history. Source of data: A throughout review of the literature found on MedLine and LILACS, as well as textbooks, dissertations, thesis, and government directives was performed. Summary of the findings: Geriatrics is the area of medicine that cares for the health and treatment of diseases in old age, which works with physical, mental, functional and social aspects in the acute, chronic, rehabilitative, preventive and palliative care of the elderly. Geriatrics goes beyond "medicine centered on organs and systems", offering holistic treatment by interdisciplinary teams with the principal objective of optimizing functional capacity and improvement of quality of life and autonomy of the elderly, which make up the core of this medical specialty. Geriatrics, in daily assistance practice, works with particular questions such as: the heterogeneity of patients and of scenarios of care; concomitance of multiple diseases/disorders (plurimorbidity), including geriatric syndromes ("the giants of geriatrics"); difficulty of identifying all the problems (iceberg phenomenon); polypharmacy; fragility; vulnerability; the various losses that the elderly show; and terminality. Conclusions: Geriatrics refers to the medical specialty responsible for the clinical aspects of aging and for the various forms of health care necessary for the elderly. Because of the complexity allied to the aging process, geriatrics has become an intriguing, challenging and contemporaneous specialty. ; Objetivos: para comemorar o centenário da Geriatria, os autores apresentam uma revisão sobre o fenômeno do envelhecimento, o indivíduo idoso, as características da medicina geriátrica e um resumo da sua história. Fonte de dados: foi realizada uma revisão da literatura através de artigos localizados nas bases MedLine e LILACS, além de livros, dissertações, teses e diretrizes ...
