Celiac disease (CeD) is one the commonest life-long diseases on a worldwide scale. The incidence today ranges from sporadic cases up to around 50 cases per 100,000 person-years and is generally increasing. The prevalence is much higher than previously thought, mostly 1% to 2% in the general population in countries where wheat is the staple food. Most cases of CeD remain undiagnosed if not proactively searched for by mass screening. Epidemiology of CeD can be positioned in 1 of 4 stages: emergence, acceleration in incidence, compound prevalence, and prevalence equilibrium. Each of these stages has its clinical challenges.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Cystic Fibrosis: Pathogenesis
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
