Crusted scabies is a rare, severe form of scabies is also called as Norwegian scabies. It is extremely contagious because of the large number of mites found in and on the skin. Crusted scabies may occur in people who are certain nutritional disorders, infectious diseases, leukemia, or weakened immune systems (such as people who have AIDS). Testing for HIV infection may be appropriate for people who have this type of scabies or people suffering with mental or nervous system disorders that mask the itching sensation. When scabies itching goes undetected, the infestation can become severe. The characteristics of crusted scabies include scaly, crusted sores on the hands, feet, scalp, face, torso, and pressure-bearing areas such as the elbows. Facial skin may flake off, and significant hair loss can result and mild itching despite the heavy infestation of mites.
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.
