Cardiology is a branch of medicine that deals with the disorders of the heart as well as some parts of the circulatory system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery. Although the cardiovascular system is inextricably linked to blood, cardiology is relatively unconcerned with hematology and its diseases. Some obvious exceptions that affect the function of the heart would be blood tests (electrolyte disturbances, troponins), decreased oxygen carrying capacity (anemia, hypovolemic shock), and coagulopathies.
Neurology is a branch of medicine dealing with disorders of the nervous system. Neurology deals with the diagnosis and treatment of all categories of conditions and disease involving the central and peripheral nervous systems (and their subdivisions, the autonomic and somatic nervous systems), including their coverings, blood vessels, and all effector tissue, such as muscle. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system. A neurologist is a physician specializing in neurology and trained to investigate, or diagnose and treat neurological disorders. Neurologists may also be involved in clinical research, clinical trials, and basic or translational research. While neurology is a nonsurgical specialty, its corresponding surgical specialty is neurosurgery. Significant overlap occurs between the fields of neurology and psychiatry, with the boundary between the two disciplines and the conditions they treat being somewhat nebulous.
Dentistry, also known as dental medicine and oral medicine, is a branch of medicine that consists of the study, diagnosis, prevention, and treatment of diseases, disorders, and conditions of the oral cavity, commonly in the dentition but also the oral mucosa, and of adjacent and related structures and tissues, particularly in the maxillofacial (jaw and facial) area. Although primarily associated with teeth among the general public, the field of dentistry or dental medicine is not limited to teeth but includes other aspects of the craniofacial complex including the temporomandibular joint and other supporting, muscular, lymphatic, nervous, vascular, and anatomical structures. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and diseases) for which reason the two terms are used interchangeably in certain regions.[where?] Dental treatments are carried out by a dental team, which often consists of a dentist and dental auxiliaries (dental assistants, dental hygienists, dental technicians, as well as dental therapists). Most dentists either work in private practices (primary care), dental hospitals or (secondary care) institutions (prisons, armed forces bases, etc.). The history of dentistry is almost as ancient as the history of humanity and civilization with the earliest evidence dating from 7000 BC. Remains from the early Harappan periods of the Indus Valley Civilization (c. 3300 BC) show evidence of teeth having been drilled dating back 9,000 years. It is thought that dental surgery was the first specialization from medicine. The modern movement of evidence-based dentistry calls for the use of high-quality scientific evidence to guide decision-making.
Dermatology is a branch of medicine that deals with the skin and diseases of the skin. It concerns the study, research and diagnosis of normal skin and disorders of the skin. Cancers, cosmetic and aging conditions of the skin, fat, hair, nails and oral and genital membranes are all aspects of dermatology. Subspecialties of the dermatology field include dermatopathology, which is involved with the pathology of the skin; immunodermatology, which specializes in the treatment of immune-mediated skin disorders, including lupus, bullous pemphigoid and pemphigus vulgaris; Mohs’ surgery, which involves removing tumors from the skin without harming healthy cells; and pediatric dermatology, in which dermatologists may treat infants, hereditary skin disorders and children. An expert in the field of dermatology is a dermatologist. A dermatologist may be involved with medical or surgical treatments. Dermatologists may perform a range of procedures, many of which are cosmetic. These include cosmetic filler injections, hair removal or transplantation, intralesional treatment, laser therapy, photodynamic therapy, phototherapy, tattoo removal, tumescent liposuction, radiation therapy and vitiligo surgery. Other treatments in the dermatology field include cryosurgery, which is the treatment of warts, skin cancers or other dermatoses; allergy testing; systemic therapies such as antibiotics, immunomodulators or injectable products; or topical therapies. The skin is the largest organ in the body. Moreover, because the entire surface area of the skin is visible, dermatologists have the advantage of direct visual examination.
Radiology is the medical discipline that uses medical imaging to diagnose and treat diseases within the bodies of both humans and animals. A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) are used to diagnose or treat diseases. Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above. The modern practice of radiology involves several different healthcare professions working as a team. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians by means of a report or verbally, and uses imaging to perform minimally invasive medical procedures. The nurse is involved in the care of patients before and after imaging or procedures, including administration of medications, monitoring of vital signs and monitoring of sedated patients. The radiographer, also known as a "radiologic technologist" in some countries such as the United States and Canada, is a specially trained healthcare professional that uses sophisticated technology and positioning techniques to produce medical images for the radiologist to interpret. Depending on the individual's training and country of practice, the radiographer may specialize in one of the above-mentioned imaging modalities or have expanded roles in image reporting.
