Prospective study of consecutive patch testing in patients with contact dermatitis using an adapted Latin American baseline series.

Summary: Background. Contact dermatitis is characterized by pruritic skin lesions with high prevalence rates. Our objective is to describe the clinical and epidemiological characteristics of a population with suspected contact dermatitis who underwent to a patch testing using an adapted Latin American baseline series.Methods. Observational, descriptive, analytical clinical study with prospective data collection was performed. 208 participants who underwent patch testing using an adapted Latin American baseline series containing 40 allergens were analyzed. The prevalence of contact allergies was compared with data from the literature. Pearson's chi-square test was used for qualitative variables. Quantitative variables were compared using the Mann-Whitney U test. The significance of the regression parameters was tested using the Wald statistical test. Results. A total of 69.7% had one or more positive tests. Among those, 82.8% were women (OR 1.371; p = 0.398). The hands were the most commonly affected site at 43%. An occupational history was detected in 19.2%. The most common allergens were nickel sulfate (32.2%), sodium tetrachloropalladate (19.7%), fragrance mix I (15.4%), and methylisothiazolinone (13.5%). In multivariate logistic regression models, nickel was significantly related to female sex, as well as palladium. Fragrance mix I was related to a family history of allergy (p less than 0.05). Methylisothiazolinone was statistically significantly related to face and hand lesions. Conclusions. This study demonstrated a detailed profile of a population with suspected allergic contact dermatitis. Our patch test results, using an adapted Latin American baseline series, represent a significant update of this important diagnostic tool.

Outcomes of enteral nutrition for patients with advanced dementia: a systematic review.

The present article aims to evaluate the outcomes of enteral nutrition for people with advanced dementia. A systematic review was conducted by searching The Cochrane Library, MEDLINE, EMBASE, PROQUEST and LILACS for articles that were published from 2008 to 2013. Prospective and retrospective studies involving a control group were searched. Data were independently extracted and assessed by one reviewer and checked by a second. Searched outcomes included survival, clinical and nutritional parameters and complications. In total, nine controlled studies were identified from several parts of the world: Israel, Italy, Japan, the United States and Brazil. Most of the studies did not report any outcome of harm with enteral nutrition use in dementia patients compared with patients without dementia. A study with a higher follow-up period demonstrated improvements in albumin, weight and chronic inflammation parameters. It is not possible to affirm that tube feeding is harmful for dementia patients. Thus, an adequate follow-up by a multidisciplinary team may lower complications associated with this therapy and thus improve survival.

Multidisciplinary care in cystic fibrosis: a clinical-nutrition review.

The multidisciplinary care, at different referral centers of cystic fibrosis, is aimed at monitoring and treating cystic fibrosis patients. Mortality attributed to this hereditary disease is high, since it affects the exocrine glands, involving multiple organs, and evolves in a chronic, progressive way. However, systemized care and the improved, shared understanding of gastroenterologists, nutritionists and pulmonologists, contribute to prolonged survival and abated morbimortality. The aim of this study is to describe the main aspects of clinical and nutritional intervention in cystic fibrosis patients so that monitoring by a multidisciplinary team is optimized and performed as early as possible. The review was carried out on articles indexed in the Medline, Lilacs, SciELO, Current Contents and Cochrane databases, finding 189 articles in Portuguese, English and Spanish, with emphasis on articles published between 2000 and 2011. Due to the scientific relevant contribution, some publications before 2000 were included totalized 77 related to the multidisciplinary care. The reviewed studies suggest that multidisciplinary care is essential for knowledge integration in order to impose permanent update of scientific information, thereby contributing to the development of intervention strategies that enhance survival and motivate the development of skills to cope with the complex treatment regimen that is necessary for cystic fibrosis treatment and prevention of related complications.

Poisonous mushrooms: a review of the most common intoxications.

Mushrooms have been used as components of human diet and many ancient documents written in oriental countries have already described the medicinal properties of fungal species. Some mushrooms are known because of their nutritional and therapeutical properties and all over the world some species are known because of their toxicity that causes fatal accidents every year mainly due to misidentification. Many different substances belonging to poisonous mushrooms were already identified and are related with different symptoms and signs. Carcinogenicity, alterations in respiratory and cardiac rates, renal failure, rhabidomyolisis and other effects were observed in toxicity studies with various species including edible and therapeutic ones. Proper identification is important to avoid accidents and toxicity studies are necessary to assure the safe use of mushrooms as food and for medicinal purposes.

Nutritional value of Agaricus sylvaticus: mushroom grown in Brazil.

The bromatological characterization of the Agaricus sylvaticus species (A. sylvaticus), known as the Sun Mushroom and cultivated in Brazil, is necessary to determine substances with pharmacological and nutritional potential, in view its safe use in food and in human medicine. The purpose of the present study was to determine the chemical composition of the A. sylvaticus mushroom grown in Brazil. Mushrooms were obtained in dehydrated form from a producer in Minas Gerais State. Through this study it was able to observe the fungus' rich chemical composition, highlighting the variety and quantity of minerals as well as its high protein content. There are many components of this mushroom that have medicinal properties, which are recognized as excellent antioxidants. Results also proved that the composition of A. sylvaticus presented differences when compared to the chemical composition of other Agaricaceae fungi.

The effects of Agaricus sylvaticus fungi dietary supplementation on the metabolism and blood pressure of patients with colorectal cancer during post surgical phase.

INTRODUCTION: Metabolic, biochemical and enzymatic alterations are common in patients with cancer. Medicinal fungi has been used as adjuvants in cancer therapy due to its immunomodulatory and nutritional effects. OBJECTIVE: The objective of this study was to evaluate the metabolic and blood pressure effects on patients with colorectal cancer after dietary supplementation with Agaricus sylvaticus. METHODS: The methodology used was a randomized, double-blind, placebo-controlled clinical trial conducted at the Base Hospital of the Federal District-Brazil. Samples of 56 patients with colorectal cancer, divided into two groups: Agaricus sylvaticus (30 mg/kg/day) and placebo. Three serum evaluations were conducted throughout the treatment: glucose, total cholesterol, triglycerides, uric acid, urea, creatinine, alkaline phosphatase; total, direct and indirect bilirubin; aspartate aminotransferase and alanine aminotransferase; immunoglobulins A (IgA), G (IgG) and M (IgM); total proteins and protein fractions; blood pressure levels were measured as well. The results were analyzed by Microsoft Excel 2003 and SPSS 14.0 programs, Student's t test, F statistical test, with p < 0.05. RESULTS: The Agaricus sylvaticus group presented a significant reduction of fasting plasma glucose (p = 0.02), total cholesterol (p = 0.01), creatinine (p = 0.05), aspartate aminotransferase (p = 0.05), alanine aminotransferase (p = 0.04), IgA (p = 0.0001), IgM (p = 0.02), systolic blood pressure (p = 0.0001) and diastolic blood pressure (p = 0.0001). These alterations were not observed in the placebo group. CONCLUSIONS: Results suggest that dietary supplementation with Agaricus sylvaticus is capable of providing metabolic benefits to the biochemical, enzymatic and blood pressure parameters of patients with colorectal cancer in the postsurgical phase.
