Medical malpractice is a legal cause of action that occurs when a medical or health care professional deviates from standards in their profession, thereby causing injury to a patient.Although the laws of medical malpractice differ significantly between nations, as a broad general rule liability follows when a health care practitioner does not show a fair, reasonable and competent degree of skill when providing medical care to a patient. If a practitioner holds himself out as a specialist a higher degree of skill is required. Jurisdictions have also been increasingly receptive to claims based on informed consent, raised by patients who allege that they were not adequately informed of the risks of medical procedures before agreeing to treatment. Online publishing has become common in scientific publishing where it has been argued that peer-reviewed scientific journals are in the process of being replaced by electronic publishing. It is also becoming common to distribute books, magazines, and newspapers to consumers through tablet reading devices, a market that is growing by millions each year
