ABSTRACT
INTRODUCTION: The purpose of this study was to evaluate the prevalence of sarcopenia in a cohort of healthy community-dwelling elderly in an urban area in Barcelona (Spain) for native benchmarks and compare them with those published in other geographical areas. MATERIAL AND METHODS: We prospectively evaluated a series of 200 healthy elderly in the community with preserved functional capacity and absence of cognitive impairment. We performed a comprehensive geriatric assessment and determined anthropometric data, muscle mass (MM) and the muscle mass index (MMI). Assessment of muscle mass was performed by bioelectrical impedance analysis (BIA). The cut-off point for defining sarcopenia MMI was established as less than 2 SD of the mean of a reference group comprising 220 healthy volunteers (20-42 years) in the same area. Results were compared with studies undertaken in the USA, France and Taiwan. RESULTS: The cut-off points obtained were 8.31 Kg/m(2) for men and 6.68 Kg/m2 for women, being similar to those observed in France and Taiwan but different from the USA. The prevalence of sarcopenia observed was 33% for elderly women and 10% for males. On comparison of the prevalence of sarcopenia in the four populations, we observed some differences, particularly in males. CONCLUSIONS: We have defined reference values for sarcopenia, determined by BIA, in our setting. We also observed a remarkable prevalence of sarcopenia in the healthy elderly community, especially in females, showing some differences from those in other geographical regions.

We present a technical modification of 3-dimensional intraoperative radiography of the kidney that reduces the cost of the material and makes preparation of the minichassis in the hospital laboratory possible. The radiogenic dose received by the kidney is 20 times less than when the system is used without screens.

A renal contact chassis that allows for the discovery of the smallest calculi and calcifications is described. The corrected images are far superior to commercially available plates and there is less radiation exposure to the patient and staff of the operating room. The bases have been established for intraoperative, 3-dimensional radiographic exploration of the kidney, which presently has not been achieved and is no doubt of great significance in operations for lithiasis. The technique represents a decisive aid for the intraoperative localization of residual calculi that allows for complete removal with a minimum of trauma to the kidney.
