[New dietetic recommendations in diabetes mellitus: the implications in enteral nutrition].

In diabetes mellitus there are qualitative and quantitative alterations in the lipid metabolism, which contribute to ischaemic heart disease. The monounsaturated fatty acids (MUFA) may favorably influence the cardiovascular risk factors, and they could replace the saturated fats, in detriment of polyunsaturated fatty acids (PUFA) and carbohydrates (CHO). A series of studies have been done, always on NIDDM patients, which have given rise to reconsidering the dietary recommendations in diabetes mellitus: There is no change in the contribution of proteins (10-20% of the caloric intake), saturated fats (< 10% of the caloric intake), dietary cholesterol (< 300 mg/day), PUFA (10% of the caloric intake), fibre (20-35 g/day), and sodium (< 2.

[Study of 288 stapedectomies performed between 1986 and 1991].

A review of 288 stapedectomies performed between 1986 and 1991 was carried out. Pre- and post-surgical (within six to nine months) audiometries were studied, analyzing the 250 Hz, 500 Hz, 1,000 Hz, 2,000 Hz and 4,000 Hz frequencies. No significant differences between age and sex, type of prosthesis or final auditive gain were found.
