From 2-dimensional to 3-dimensional: Overcoming dilemmas in intestinal mucosal interpretation.

From 2-dimensional to 3-dimensional: Overcoming dilemmas in intestinal mucosal interpretation. World J Gastroenterol. 2019 May 28;25(20):2402-2415 Authors: Charlesworth RP, Marsh MN Abstract The purpose of this review is to provide a definitive account of small intestinal mucosal structure and interpretation. The coeliac lesion has been well known, but not well described to date and this review aims to identify the interpretative difficulties which have arisen over time with the histological assessment of coeliac disease. In early coeliac interpretation, there were significant inaccuracies, particularly surrounding intraepithelial lymphocyte counts and the degree of villous flattening which occurred in the tissue. Many of these interpretive pitfalls are still encountered today, increasing the potential for diagnostic errors. These difficulties are mostly due to the fact that stained 2-dimensional sections can never truly represent the 3-dimensional framework of the intestinal tissue under investigation. Therefore, this review offers a critical account occasioned by these 2-dimensional interpretative errors and which, in our opinion, should in general be jettisoned. As a result, we leave a framework regarding the true 3-dimensional knowledge of mucosal structure accrued over the 70-year period of study, and one which is available for future reference.

M. Yassine For a long time, viruses have been shown to modify the clinical picture of several autoimmune diseases, including type 1 diabetes (T1D), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Sjögren’s syndrome (SS), herpetic stromal keratitis (HSK), celiac disease (CD), and multiple sclerosis (MS). Best examples of viral infections that have been proposed to modulate the induction and development of autoimmune diseases are the infections with enteric viruses such as Coxsackie B virus (CVB) and rotavirus, as well as influenza A viruses (IAV), and herpesviruses. Other viruses that ...

AbstractBackgroundDespite the increasing number of publications on celiac disease, there is a lack of studies that made a holistic bibliometric evaluation of the studies on this topic.AimsThe purpose of this study is to analyze the publications about celiac disease by using bibliometric methods and this way to demonstrate the celiac disease –related trends, top effective articles, journals, and international collaborations between the countries and institutions.MethodsAll articles published between 1980 and 2018 on celiac disease were downloaded from Web of Science and analyzed with bibliometric methods. The correlat...

(CNN) — Bad news for lovers of bread, pasta and baked goods: Eating lots of gluten-heavy foods from a young age could eventually lead to gluten intolerance. A study published Tuesday in the journal JAMA suggests that eating higher-than-normal levels of gluten during the first five years of life can increase a child’s likelihood of developing celiac disease, a digestive disorder that damages the small intestine. Higher gluten intake was associated with a 6.1% increased risk of celiac disease autoimmunity, an immunological response to gluten, and a 7.2% increased risk of celiac disease per each additional gram or...
