Surgeon
In modern medicine, a surgeon is a medical professional who performs surgery. Although there are different traditions in different times and places, a modern surgeon usually is also a licensed physician or received the same medical training as physicians before specializing in surgery. There are also surgeons in podiatry, dentistry, and veterinary medicine. It is estimated that surgeons perform over 300 million surgical procedures globally each year. History The first person to document a surgery was the 6th century BC Indian physician-surgeon, Sushruta. He specialized in cosmetic plastic surgery and even documented an open rhinoplasty procedure.Ira D. Papel, John Frodel, ''Facial Plastic and Reconstructive Surgery'' His magnum opus ''Suśruta-saṃhitā'' is one of the most important surviving ancient treatises on medicine and is considered a foundational text of both Ayurveda and surgery. The treatise addresses all aspects of general medicine, but the translator G. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperparathyroidism
Hyperparathyroidism is an increase in parathyroid hormone (PTH) levels in the blood. This occurs from a disorder either within the parathyroid glands ( primary hyperparathyroidism) or as response to external stimuli (secondary hyperparathyroidism). Symptoms of hyperparathyroidism are caused by inappropriately normal or elevated blood calcium leaving the bones and flowing into the blood stream in response to increased production of parathyroid hormone. In healthy people, when blood calcium levels are high, parathyroid hormone levels should be low. With long-standing hyperparathyroidism, the most common symptom is kidney stones. Other symptoms may include bone pain, weakness, depression, confusion, and increased urination. Both primary and secondary may result in osteoporosis (weakening of the bones). In 80% of cases, primary hyperparathyroidism is due to a single benign tumor known as a parathyroid adenoma. Most of the remainder are due to several of these adenomas. Very rar ...

Francis Daniels Moore
Francis Daniels Moore (April 17, 1913, in Evanston, Illinois – November 24, 2001, in Westwood, Massachusetts) was an American surgeon who was a pioneer in numerous experimental surgical treatments. Among his many achievements, he refined Burn (injury), burn-treatment techniques, helped perform the world's first successful Organ transplantation, organ transplant (which involved a kidney), and accurately determined the volume of water and other nutrients in the human body using radioactive isotopes of those substances. In 1952, Moore became a member of the American Academy of Arts and Sciences. He was awarded the 1978 Lister Medal for his contributions to surgical science. The corresponding Lister Oration, given at the Royal College of Surgeons of England, was delivered on May 23, 1979, and was titled "Science and service". He later became a member of both the National Academy of Sciences and the American Philosophical Society. Moore graduated from Harvard in 1935, where he was pr ...

Tannic Acid
Tannic acid is a specific form of tannin, a type of polyphenol. Its weak acidity ( pKa around 6) is due to the numerous phenol groups in the structure. The chemical formula for commercial tannic acid is often given as C76H52O46, which corresponds with decagalloyl glucose, but in fact it is a mixture of polygalloyl glucoses or polygalloyl quinic acid esters with the number of galloyl moieties per molecule ranging from 2 up to 12 depending on the plant source used to extract the tannic acid. Commercial tannic acid is usually extracted from any of the following plant parts: Tara pods ('' Caesalpinia spinosa''), gallnuts from ''Rhus semialata'' or '' Quercus infectoria'' or Sicilian sumac leaves ('' Rhus coriaria''). According to the definitions provided in external references such as international pharmacopoeia, Food Chemicals Codex and FAO-WHO tannic acid monograph only tannins obtained from the above-mentioned plants can be considered as tannic acid. Sometimes extracts from che ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanning (leather)
Tanning is the process of treating skins and hides of animals to produce leather. A tannery is the place where the skins are processed. Tanning hide into leather involves a process which permanently alters the protein structure of skin, making it more durable and less susceptible to decomposition and coloring. Before tanning, the skins are dehaired, degreased, desalted and soaked in water over a period of six hours to two days. Historically this process was considered a noxious or "odoriferous trade" and relegated to the outskirts of town. Historically, tanning used tannin, an acidic chemical compound from which the tanning process draws its name, derived from the bark of certain trees. An alternative method, developed in the 1800s, is chrome tanning, where chromium salts are used instead of natural tannins. History The English word for tanning is from medieval Latin , derivative of ( oak bark), from French (tanbark), from old-Cornish (red oak). These terms are rel ...

Richard Schatzki
Richard Schatzki (1901–1992) was a Germans, German-United States, American radiologist. He was born in Klafeld, Germany on February 22, 1901. In 1933, Nazi leadership declared that no one of Jewish background could hold a position in German governmental facilities. As a result, Schatzki was forced to leave his University Hospital position. Four months later, Schatzki moved to America with his wife Greta and young son Stefan. They were the first Schatzkis to leave Germany, although other family members would join them in America in the years leading up to the war as conditions in Germany deteriorated further. Upon leaving his home nation, Germany, his wife was pregnant with their second son. After arriving in the United States, George Schatzki came into the world. He trained in radiology in Berlin with Hans Heinrich Berg (1889-1968) who was the leading diagnostic radiologist in Germany at that time. He immigrated to the United States in 1933 and worked as a radiologist physician in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benjamin Castleman
Benjamin Castleman (May 17, 1906, Everett, Massachusetts – June 29, 1982, Boston, Massachusetts) was an American physician and pathologist best known for describing Castleman's disease (angiofollicular lymphoid hyperplasia), which is named after him. He was also one of the authors of the first case series on pulmonary alveolar proteinosis in a 1958 article in the ''New England Journal of Medicine''. ("Rosen–Castleman–Liebow syndrome" is a rarely used term for that condition.) Castleman undertook clinicopathologic investigations of parathyroid disease and wrote several important papers on diseases of the thymus and mediastinum. He wrote, or collaborated in writing, over 100 scholarly papers on a variety of disorders. Castleman grew up in a Jewish religious household and was educated at Harvard University (B.A., 1927) and Yale University (M.D., 1931). He worked for many years at the Massachusetts General Hospital in Boston, serving as chief of the division of anatomic pa ...

Cocoanut Grove Fire
The Cocoanut Grove fire was a nightclub fire which took place in Boston, Massachusetts, United States, on November 28, 1942, and resulted in the deaths of 492 people. It is the deadliest nightclub fire in U.S. history, and the second-deadliest single-building fire (after the Iroquois Theatre fire). The Cocoanut Grove was one of Boston's most popular nightspots, attracting many celebrity visitors. It was owned by Barnet "Barney" Welansky, who was closely connected to the Mafia and to Mayor Maurice J. Tobin. Fire regulations had been flouted: some exit-doors had been locked to prevent unauthorized entry, and the elaborate palm tree décor contained flammable materials. The air-conditioning used flammable gas due to wartime shortage of freon. During the first Thanksgiving weekend since the U.S. had entered World War II the Grove was filled to more than twice its legal capacity. The fire was initiated by an electrical short and fueled by methyl chloride in the air conditioning uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluid Replacement
Fluid replacement or fluid resuscitation is the medical practice of replenishing bodily fluid lost through sweating, bleeding, fluid shifts or other pathologic processes. Fluids can be replaced with oral rehydration therapy (drinking), intravenous therapy, rectally such as with a Murphy drip, or by '' hypodermoclysis'', the direct injection of fluid into the subcutaneous tissue. Fluids administered by the oral and hypodermic routes are absorbed more slowly than those given intravenously. By mouth Oral rehydration therapy (ORT) is a simple treatment for dehydration associated with diarrhea, particularly gastroenteritis/gastroenteropathy, such as that caused by cholera or rotavirus. ORT consists of a solution of salts and sugars which is taken by mouth. For most mild to moderate dehydration in children, the preferable treatment in an emergency department is ORT over intravenous replacement of fluid., which cites: * It is used around the world, but is most important in the devel ...

Thyroid
The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans it is in the neck and consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the thyroid isthmus. The thyroid is located at the front of the neck, below the Adam's apple. Microscopically, the functional unit of the thyroid gland is the spherical thyroid follicle, lined with follicular cells (thyrocytes), and occasional parafollicular cells that surround a lumen containing colloid. The thyroid gland secretes three hormones: the two thyroid hormones triiodothyronine (T3) and thyroxine (T4)and a peptide hormone, calcitonin. The thyroid hormones influence the metabolic rate and protein synthesis, and in children, growth and development. Calcitonin plays a role in calcium homeostasis. Secretion of the two thyroid hormones is regulated by thyroid-stimulating hormone (TSH), which is secreted from the anterior pituitary gland. TSH is reg ...

Hyperplasia
Hyperplasia (from ancient Greek ὑπέρ ''huper'' 'over' + πλάσις ''plasis'' 'formation'), or hypergenesis, is an enlargement of an organ or tissue caused by an increase in the amount of organic tissue that results from cell proliferation. It may lead to the gross enlargement of an organ, and the term is sometimes confused with benign neoplasia or benign tumor. Hyperplasia is a common preneoplastic response to stimulus. Microscopically, cells resemble normal cells but are increased in numbers. Sometimes cells may also be increased in size (hypertrophy). Hyperplasia is different from hypertrophy in that the adaptive cell change in hypertrophy is an increase in the ''size'' of cells, whereas hyperplasia involves an increase in the ''number'' of cells. Causes Hyperplasia may be due to any number of causes, including proliferation of basal layer of epidermis to compensate skin loss, chronic inflammatory response, hormonal dysfunctions, or compensation for damage ...
