The perioperative management of patients undergoing abdominal surgery has been based on traditional concepts and often not supported by scientific evidence. Recently there have been several scientific studies showing that some traditional procedures for the perioperative management of patients as preoperative fasting, bowel preparation, use of naso-gastric tubes, placement of intra-abdominal drainage, postoperative fasting etc. They are unnecessary and sometimes counterproductive. Perioperative management protocols ERAS or Fast-Track (Enhanced Recovery After Surgery) are based on the use in the perioperative period of measures that are supported by current scientific evidence. Since 2000 appear in the scientific literature several works that reflect the application of protocols ERAS or Fast- Track in surgery of the digestive system where it's shown uniformly, not only the security of your application but also, decreased complications and hospital stay. Although initially these protocols were described in colorectal surgery, due to the good results obtained, the application of these protocols has rapidly expanded to other surgical specialties such as thoracic surgery, Urology, Gynaecology, etc. In all these specialties has unanimously showing improved postoperative recovery with ERAS application protocols. The purpose of this paper is twofold. On the one hand examine the scientific evidence that exists today on the most important elements of an ERAS program and present preliminary results of the implementation of a program ERAS in our hospital.

Adrenal myelolipomas are rare benign tumors comprising mature adipose tissue and diverse hematopoietic elements. These neoplasms are usually incidental findings, although bulky masses can generate abdominal pain as well as other symptoms related to compression of adjacent organs. Diagnosis is usually provided by ultrasonography or computed tomography. Asymptomatic patients with tumors with a maximum diameter of less than 6cm can benefit from periodic surveillance, whereas local compression symptoms and size larger than 6cm are indications for surgical treatment. We present a case of giant adrenal myelolipoma and provide a review of the literature., (Copyright © 2008 Sociedad Española de Endocrinología y Nutrición. Published by Elsevier Espana.

The concept of functional food, about which scientific agreement is still lacking, springs from the field of Optimum Nutrition, aimed at modifying genetic and physiological aspects of human life and at the prevention and treatment of a growing number of diseases, far beyond merely covering nutritional requirements. From the European Union perspective, functional foods can be natural as well as industrially processed foods. The leading functional foods regarding which the soundest scientific evidence exists are probiotics, live microbial food ingredients represented mainly by fermented dairy products. Prebiotics, such as inulin-type fructans, are the trophic substrate of probiotics and potential intestinal microflora selectors. The combination of prebiotics and probiotics is termed synbiotic. Innumerable substances are known to have functional effects: soluble and insoluble fiber, phytosterols, phytoestrogens, monounsaturated and polyunsaturated fatty acids, phenol derivatives, vitamins and other phytochemicals. Functional foods exert their actions on different systems, especially the gastrointestinal, cardiovascular and immunological ones, acting too as enhancers of development and differentiation and positively modulating nutrient metabolism, gene expression, oxidative stress and the psychic sphere. The establishment of Health Claims must be firmly based upon scientific knowledge and legal regulation. Efficient biomarkers related to biological response must be found. Furthermore, it is essential to analyze possible diet or drug interactions as well as it is indispensable to conduct valid studies on humans. The prime objective must be the diet as a whole. Thus, the future challenge of a functional diet emerges.

Objectives: To assess reliability in terms of inter-observer agreement of blood pressure (BP) readings. Various health professionals and measuring systems. Influence of observer's experience., Design: Observational, descriptive, cross-sectional study., Setting: Urban health centre, Córdoba., Participants: 131 hypertensive, randomised patients, belonging to a functional care unit. 11 were excluded., Measurements: To reduce variability: course on the right way to take blood pressure, otoscope and verification of visual sharpness of observers, calibration and validation of measuring devices, limited time and blinding of measurements. 4 BP measurements per patient: 3 with mercury sphygmomanometer (2 simultaneously, one individual) and one with an automatic device. Descriptive, clinical and somatometric variables were gathered. Inter-observer agreement was evaluated through the intraclass correlation coefficient (ICC), the mean of differences method (MDM) and the simple concordance index (CI). An ICC > 0.75 was thought acceptable. A difference > 5 mmHg was thought clinically relevant (MDM and CI)., Main Results: Acceptable consistency for MDM: alone, systolic and diastolic pressure of OBS 1/ OBS 2, bi-auricular, -6.1/+8.9 mmHg and -6.8/+5.8 mmHg. Less favourable results: for systolic and diastolic pressure: OBS 1/AUTO -20.9/25.0 and -16.4/15.1; OBS 2/AUTO -22.8/24.4 and -16.6/15.2. Remaining intervals always > 10 mmHg; CI > 0.75 in all comparisons except diastolic pressure OBS 1/AUTO and diastolic pressure OBS 2/AUTO (0.69 in both cases). 41% of comparisons were > 5 mmHg. No differences in less expert professionals were found., Conclusions: Inaccuracy of the standard BP measurement method (mercury sphygmomanometer) for MDM and CI. Contradictory conclusions according to method of measurement. Differences not clinically acceptable.
