Disease is an abnormal condition of an organism that will exhibit specific symptoms and affects regular metabolism. It may be caused by external factors generally referred as foreign particles and will produce infectious diseases. These foreign particles will act as antigens, which will react with our immune system and finally leading to disease condition. Sometimes diseases will be produced by internal dysfunctions, which will lead to autoimmune diseases. Infectious diseases are transmissible diseases and these transmissible diseases will spread or transmit from one person to the other and will become more resistant. Some of the infectious diseases include measles, syphilis, tuberculosis, etc. Auto immune diseases will not spread through any external factor and these diseases generally produce by our own body and sometimes these autoimmune diseases will lead to death. Some of the auto immune diseases include autoimmune hemolytic anemia, addison's disease, berger's disease, etc. Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
