Anemia remains a global health problem in the 21stcentury. Iron deficiency anemia is the most common type. Childrenare especially vulnerable to the detrimental health consequences of anemia including fatigability, predisposition to repeated infections, and cognitive impairment. Iron deficiency anemia is considered the most prevalent type of nutritional anemia. Insufficient dietary iron intake, decreased iron absorption, and excess iron loss can cause iron deficiency.Accordingly, malnutrition plays a role in the prevalence of iron deficiency anemia. Saudi Arabia is now in advanced nutrition transition, which means the rates of obesity are high together with malnutrition. In this review, we shed light on the prevalence of iron deficiency anemia among the pediatric population of the Kingdom of Saudi Arabia. We also focus on the burden of malnutrition and its association with anemia, and evaluate the strategies needed to combat these health problems. Further research all over the Kingdom is needed to expose the full magnitude of anemia. Monitoring of the implementation of the previously existing health programs is needed.
Idiopathic inflammatory myopathies (IIMs) includes an unusual group of acute, chronic, and subacute developed diseases of skeletal muscle characterized by moderate to severe muscle weakness and inflammation.Polymyositis is generally considered to be a prototypic T cell-mediated autoimmune myopathy, while DM was traditionally associated with a humoral-driven microangiopathy, though the putative autoantibodies and their targets have yet to be identified, and there is increasing evidence implicating the type I interferon pathway in the pathogenesis of the disease. Women between the ages of 50 and 70 are the most typically affected. Proximal muscular weakness is the most common clinical symptom. Inflammatory arthritis, Raynaud's phenomenon, myocarditis, and interstitial lung disease are all examples of extramuscular involvement. In this review, we overview updates in diagnosis and managements of polymyositis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
