[Ethics in contemporary medicine].

Medical practice has been traditionally ruled by the principles of medical ethics and the scientific aspects that define it. However, today's medical practice is largely influenced by other aspects such as: economic interests, abuse of therapeutics, defensive medicine, unnecessary surgeries and conflicts of interests without excluding alterations in the application of the informed consent, the relation with the pharmaceutical industry, respect of confidentiality, organizational ethics, and the ethical practice that escapes the will of the medical professional.
