Medical specialty
Informal social recognition of medical specialization evolved before the formal legal system.Pediatricians handle most complaints and diseases in children that do not require surgery, and there are several subspecialties (formally or informally) in pediatrics that mimic the organ-based specialties in adults.This line is becoming somewhat blurred with interventional radiology, an evolving field that uses image expertise to perform minimally invasive procedures.For specialists working in the province of Quebec, the Collège des médecins du Québec also oversees the process.Each of these agencies and their associated national medical organization functions as its various specialty academies, colleges and societies.All boards of certification now require that medical practitioners demonstrate, by examination, continuing mastery of the core knowledge and skills for a chosen specialty.Developing countries and poor areas usually have shortages of physicians and specialties, and those in practice usually locate in larger cities.[15] A survey of physicians in the United States came to the result that dermatologists are most satisfied with their choice of specialty followed by radiologists, oncologists, plastic surgeons, and gastroenterologists.[16] Surveys have also revealed high levels of depression among medical students (25 - 30%) as well as among physicians in training (22 - 43%), which for many specialties, continue into regular practice.
