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.
Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
Open Access raises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
