Revista médica de Chile , 2008, DOI: 10.4067/S0034-98872008000500010
Abstract: celiac disease requires a strict gluten free diet for life for proper recovery. this results in higher feeding costs. aim: to analyze the cost of basic food basket (bfb) compared to a basket especially designed for celiac patients in chile and to estimate the increment in food spending that these patients experience. material and methods: the cost of a daily bfb was calculated using the national socioeconomic characterization enquiry (casen) methodology of the ministry of planning and the food prices delivered by the national institute of statistics for consumers, adjusted according to consumer prices at june 2007. to calculate the cost of the basket for celiac disease, equivalent foods without gluten were considered. their daily and monthly values and the percentage difference between them were analyzed, by food groups and type of basket. results: the monthly value of bfb and a basket for a celiac is, at june 2007, ch $ 30.251 and ch $ 57.250, respectively. this represents an increase in feeding costs for celiac patients of 89%. conclusions: the greater cost of food without gluten represents a ?imitation in the budget of celiac patients

Abstract: efficacy of a national program to promote breast feeding: chile 1993-2002. promotion of breast feeding is a priority in chilean health's policies. the aim of the study was to evaluate the tendency of breastfeeding (exclusive, continued, partial), in children less than 18 months old, controlled in the chilean public health system, based in four national surveys. through a 24 h food intake recall (breastfeeding, water, juice, infant formula, solids) food patterns were explored every 3 years, as well as maternal participation in jobs located away from home. the sample consisted of ~ 10 thousand children, less than 18 months old of the 28 health services throughout the country. the prevalence of children with exclusive breastfeeding, predominant (breastfeeding, water or juice), complemented (breastfeeding plus solids) or any other way of feeding for each month of age in each survey, and changes in period studied, was determined. between 1993 and 2002, exclusive breastfeeding for 6 months increased from 16 to 43.1% (p<0.001) and predominant breastfeeding from 25.4 to 57.4%. at the same time, complemented breastfeeding at 12 months increased from 10.7 to 21.3%, and partial or complemented breastfeeding in 12 to 18 month old children went from 24.1 to 46.7%. maternal work located away from home was inversely associated with the prevalence of exclusive and complemented breastfeeding during the first year (p<0.001). there has been a significant increase of maternal breastfeeding in the period analyzed. the negative effects of maternal labor on breastfeeding suggests to explore more effective forms of social support to the working mother.

Abstract: an increased folate intake may be beneficial in deficient populations. however, in women with adequate levels it may not deliver additional benefits while it may increase the risk for some forms of cancer. a systematic literature review of benefits or risks of folate in the development of breast cancer was performed using medline, systematic review of selected articles and references of the selected articles looking specifically at serum folate levels, dietary folate intake or total folate intake and the risk of developing breast cancer. fourteen case-control studies, fourteen cohort studies, seven case-control nested studies, two randomized trials and two meta-analyses were selected for analysis based on pre-established criteria. the reviewed evidence does not support the hypothesis that higher intakes of dietary folate reduce the risk for breast cancer. some studies showed a higher risk of breast cancer in populations exposed to high folate intake post fortification, especially when folic acid is used. the results support the need to be cautious and to limit the exposure of women to high intakes of folic acid, especially in countries with mandatory food fortification.

Abstract: Background: Celiac disease (CD) is an immune-mediated enteropathy triggered by the ingestion of gluten in genetically susceptible individuals. Its prevalence in Europe and the USA is 0.5 to 1%. Aim: To analyze epidemiological aspects and degree of compliance with gluten-free diet (GFD) among Chilean individuals with CD. Material and Methods: Subjects with confirmed or suspected CD were invited to answer an online survey published on the web at www.fundacionconvivir.cl. The answers were reinforced with a telephone interview. Results: The survey was answered by 1212 subjects (79% females). Median age at diagnosis was 25.8 years (range 1 to 84 years), with a bimodal curve with two peaks at less than 3 years and at 20 to 40 years of age. The diagnosis was made only by serologic markers in 9%, only by intestinal biopsy in 17.5%, and by a combination of both methods in 70%o. Conditions associated with CD were reported by 30%> of subjects and 20%> had relatives with CD. The GFD was strictly adhered to by 70%>, occasionally by 27%> and never by 3%>. Seventy five percent of subjects with a strict adherence to GFD had a favorable clinical response compared with 42%> of those with incomplete or lack of adherence (odds ratio 4.0, 95%> confidence intervals 2.8-5.7p < 0.01). Conclusions: In 30% of respondents, the diagnosis of CD was not confirmed according to international guidelines that require serology and duodenal biopsy. One third of subjects recognized a poor compliance with GFD. Those with a strict adherence to it had a more favorable clinical course. However, 25%> did not experience a clinical improvement despite a strict GFD, a finding which requires further study.

Abstract: Background: High daily intake of folic acid (FA) could determine health risks in some populations. Aim: To review the Chilean FA wheat four fortifcation and to identify the existence of populations at risk. Material and Methods: We categorized the FA levels in four samples (percentil P) (2005-2008) and estimated intake of FA (mg/d) in adults from apparent bread consumption according to different levels (P20, 50 and 95) and children consumption (8-13 years) considering socioeconomic status (SES), bread/g/d intake (P20, 50 and 75) and regulated level of four fortifcation (2.2 mg FA/100 g). Daily Dietary Folate Equivalent (DFE) consumption was estimated from serum folate in adults and elderly people (both sexes). We calculated the percentage of population with FA intakes over the estimated average requirement (EAR) and maximum level (UL) pre and post-fortifcation. Results: There is great variability in FA four: 10-20% samples without FA and 10-30% with levels > 2.2 mg/100 g. Adult daily consumption (2-4 day/loaves) could determine FA intakes close to UL. Children daily bread consumption (low socioeconomic level) > P75 have intakes close to UL. Post-fortifcation estimated daily DFE from serum folate in women, men and elderly people show: 99% of women, 100% of men and the elderly people have intakes higher than EAR. Additionally 2.3% of women and 6% of men would have intakes near the UL. Conclusions: The four FA levels and serum folate levels in some populations show increased FA post-fortifcation intakes, which could lead to greater risk suggesting a revision of the fortifcation level.

Abstract:
Endoscopic ultrasound in the papilla and the periampullary region
Cecilia Castillo
World Journal of Gastrointestinal Endoscopy , 2010,
Abstract: Endoscopic ultrasound (EUS) provides relevant information when an ampullary or periampullary tumor is suspected. Early detection, T and N staging and Fine Needle Aspiration plus cithologic confirmation, are some of the expected benefits. Exclusion of benign findings like choledocholithiasis or chronic pancreatitis is also important. A correct understanding of the complex ampullary and periampullary anatomy is needed. Knowledge of the individual clinical history and other previous diagnostic images all contribute to a successful EUS examination. Radial and lineal EUS images are uniquely detailed and, at the moment, it seems to be the best way to exclude or confirm malignant or benign findings. We propose a procedural algorithm, including EUS, for suspected ampullary or periampullary tumors. This review summarizes the vast amount of information to be found spread in the literature, and recognizes this small anatomic area as the origin for a clinical entity with proper clinical presentation, proper imaging and proper therapeutic resolutions. The benefits of performing EUS for its study are highlighted.
