Tertiary Hospital
A tertiary referral hospital (also called a tertiary hospital, tertiary referral center, tertiary care center, or tertiary center) is a hospital that provides tertiary care, which is a level of health care obtained from specialists in a large hospital after referral from the providers of primary care and secondary care. Beyond that general definition, there is no precise narrower or more formal definition, but tertiary centers usually include the following: *a major hospital that usually has a full complement of services including pediatrics, obstetrics, general medicine, gynecology, various branches of surgery and psychiatry or *a specialty hospital dedicated to specific sub-specialty care (pediatric centers, oncology centers, psychiatric hospitals). Patients will often be referred from smaller hospitals to a tertiary hospital for major operations, consultations with sub-specialists and when sophisticated intensive care facilities are required. Some examples of tertiary referra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hospital
A hospital is a healthcare institution providing patient treatment with specialized Medical Science, health science and auxiliary healthcare staff and medical equipment. The best-known type of hospital is the general hospital, which typically has an emergency department to treat urgent health problems ranging from fire and accident victims to a sudden illness. A district hospital typically is the major health care facility in its region, with many beds for intensive care and additional beds for patients who need long-term care. Specialized hospitals include trauma centers, rehabilitation hospitals, children's hospitals, geriatric hospitals, and hospitals for specific medical needs, such as psychiatric hospitals for psychiatry, psychiatric treatment and other disease-specific categories. Specialized hospitals can help reduce health care costs compared to general hospitals. Hospitals are classified as general, specialty, or government depending on the sources of income received. ...

Positron Emission Tomography
Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging purposes, depending on the target process within the body, such as: * Fluorodeoxyglucose ( 18F">sup>18FDG or FDG) is commonly used to detect cancer; * 18Fodium fluoride">sup>18Fodium fluoride (Na18F) is widely used for detecting bone formation; * Oxygen-15 (15O) is sometimes used to measure blood flow. PET is a common imaging technique, a medical scintillography technique used in nuclear medicine. A radiopharmaceutical—a radioisotope attached to a drug—is injected into the body as a tracer. When the radiopharmaceutical undergoes beta plus decay, a positron is emitted, and when the positron interacts with an ordinary electron, the tw ...

Hospital Ship
A hospital ship is a ship designated for primary function as a floating healthcare, medical treatment facility or hospital. Most are operated by the military forces (mostly navy, navies) of various countries, as they are intended to be used in or near war zones. In the 19th century, redundant warships were used as moored hospitals for seamen. The Second Geneva Convention, Second Geneva Convention of 1949 prohibits military attacks on hospital ships that meet specified requirements, though belligerent forces have right of inspection and may take patients, but not staff, as prisoner of war, prisoners of war. History Early examples Hospital ships possibly existed in ancient times. The Athenian military, Athenian Navy had a ship named ''Therapia'', and the Roman Navy had a ship named ''Aesculapius'', their names indicating that they may have been hospital ships. The earliest British hospital ship may have been the vessel ''Goodwill'', which accompanied a Royal Navy squadron in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hospital Train
A hospital train is a railway train with carriages equipped for the provision of healthcare. Historically this has ranged from trains equipped to transport wounded soldiers, with basic nursing and first aid facilities on board, to fully equipped mobile medical centres, sometimes including operating theatres and nursing wards. History Origins The first hospital train was built during the Crimean War in the 1850s. Poorly operated logistical supply networks and inadequate health provisions for the British army encamped around the Russian port of Sevastopol caused a public outcry in England. To alleviate these problems, the Grand Crimean Central Railway was initially built by a partnership of English railway contractors led by Samuel Morton Petoin 1855, to supply ammunition and provisions to Allied soldiers. Within three weeks of the arrival of the fleet carrying materials and men the railway had started to run and in seven weeks of track had been completed. The railway was a ...

Secondary Hospital
A secondary hospital, secondary referral center or a secondary care center is a healthcare facility that provides specialized medical care and support for patients referred from primary healthcare centers. Secondary hospitals typically serve as a bridge between primary care and tertiary hospitals, which offer highly specialized treatment. They are usually equipped to handle more complex medical conditions than primary centers, often including departments for surgery, general medicine, obstetrics, pediatrics, and emergency care. Secondary hospitals play a critical role in the healthcare system, offering services that are beyond the scope of primary healthcare centers but do not require the advanced technology and specialist resources found in tertiary hospitals. They may serve a designated population area and work closely with primary healthcare providers to ensure continuity of patient care.

History Of Hospitals
The history of hospitals began in antiquity with hospitals in Greece, the Roman Empire and on the Indian subcontinent as well, starting with precursors in the Asclepian temples in ancient Greece and then the military hospitals in ancient Rome. The Greek temples were dedicated to the sick and infirm but did not look anything like modern hospitals. The Romans did not have dedicated, public hospitals. Public hospitals, per se, did not exist until the Christian period. Towards the end of the 4th century, the "second medical revolution" took place with the founding of the first Christian hospital in the eastern Byzantine Empire by Basil of Caesarea, and within a few decades, such hospitals had become ubiquitous in Byzantine society. The hospital would undergo development and progress throughout Byzantine, medieval European and Islamic societies from the 5th to the 15th century. European exploration brought hospitals to colonies in North America, Africa, and Asia. St Bartholomew's hos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poisoning
Poisoning is the harmful effect which occurs when Toxicity, toxic substances are introduced into the body. The term "poisoning" is a derivative of poison, a term describing any chemical substance that may harm or kill a living organism upon ingestion. Poisoning can be brought on by swallowing, inhaling, injecting or absorbing toxins through the skin. Toxicology is the practice and study of symptoms, mechanisms, diagnoses, and treatments correlated to poisoning. Levels of Exposure When a living organism is introduced to a poison, the Signs and symptoms, symptoms that follow successful contact develop in Dose–response relationship, close relation to the degree of exposure. Acute exposure Acute toxicity, Acute toxicity/poisoning consists of a living organism being harmfully exposed to poison once or more times during a brief period, with symptoms manifesting within 14 days since administration. Chronic exposure Chronic toxicity, Chronic toxicity/poisoning involves a li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurosurgery
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the specialty (medicine), medical specialty that focuses on the surgical treatment or rehabilitation of disorders which affect any portion of the nervous system including the Human brain, brain, spinal cord, peripheral nervous system, and cerebrovascular system. Neurosurgery as a medical specialty also includes non-surgical management of some neurological conditions. Education and context In different countries, there are different requirements for an individual to legally practice neurosurgery, and there are varying methods through which they must be educated. In most countries, neurosurgeon training requires a minimum period of seven years after graduating from medical school.

Puberty
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a female, the testicles in a male. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed. Before puberty, the external sex organs, known as primary sexual characteristics, are sex characteristics that distinguish males and females. Puberty leads to sexual dimorphism through the development of the secondary sex characteristics, which further distinguish the sexes. On average, females begin puberty at age 10½ and complete puberty at ages 15-17; males begin at ages 11½-12 and complete pube ...

Chemotherapy
Chemotherapy (often abbreviated chemo, sometimes CTX and CTx) is the type of cancer treatment that uses one or more anti-cancer drugs (list of chemotherapeutic agents, chemotherapeutic agents or alkylating agents) in a standard chemotherapy regimen, regimen. Chemotherapy may be given with a cure, curative intent (which almost always involves combinations of drugs), or it may aim only to prolong life or to Palliative care, reduce symptoms (Palliative care, palliative chemotherapy). Chemotherapy is one of the major categories of the medical discipline specifically devoted to pharmacotherapy for cancer, which is called ''oncology#Specialties, medical oncology''. The term ''chemotherapy'' now means the non-specific use of intracellular poisons to inhibit mitosis (cell division) or to induce DNA damage (naturally occurring), DNA damage (so that DNA repair can augment chemotherapy).
