Surgeon
In medicine, a surgeon is a medical doctor who performs surgery. Even though there are different traditions in different times and places, a modern surgeon is a licensed physician and received the same medical training as physicians before specializing in surgery. In some countries and jurisdictions, the title of 'surgeon' is restricted to maintain the integrity of the craft group in the medical profession. A specialist regarded as a legally recognized surgeon includes 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.Papel, Ira D. and Frodel, John (2008) ''Facial Plastic and Reconstructive Surgery''. Thieme Medical Pub.

Tracheotomy
Tracheotomy (, ), or tracheostomy, is a surgical airway management procedure which consists of making an incision on the front of the neck to open a direct airway to the trachea. The resulting stoma (hole) can serve independently as an airway or as a site for a tracheal tube (or tracheostomy tube) to be inserted; this tube allows a person to breathe without the use of the nose or mouth. Etymology and terminology The etymology of the word ''tracheotomy'' comes from two Greek words: the root ''tom-'' (from Greek τομή ''tomḗ'') meaning "to cut", and the word ''trachea'' (from Greek τραχεία ''tracheía''). The word ''tracheostomy'', including the root ''stom-'' (from Greek στόμα ''stóma'') meaning "mouth", refers to the making of a semi-permanent or permanent opening and to the opening itself. Some sources offer different definitions of the above terms. Part of the ambiguity is due to the uncertainty of the intended permanence of the stoma (hole) at the time i ...

Tracheal Intubation
Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic catheter, tube into the vertebrate trachea, trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs. It is frequently performed in critically injured, ill, or anesthetized patients to facilitate Ventilation (physiology), ventilation of the lungs, including mechanical ventilation, and to prevent the possibility of asphyxiation or airway obstruction. The most widely used route is orotracheal, in which an tracheal tube, endotracheal tube is passed through the mouth and larynx, vocal apparatus into the trachea. In a nasotracheal procedure, an endotracheal tube is passed through the nose and vocal apparatus into the trachea. Other methods of intubation involve surgery and include the cricothyrotomy (used almost exclusively in emergency circumstances) and the tracheotomy, used primarily in situations where a prolonged need for air ...

William Macewen
Sir William Macewen ( ; 22 June 1848 – 22 March 1924) was a Scottish surgeon. He was a pioneer in modern brain surgery, considered the ''father of neurosurgery'' and contributed to the development of bone graft surgery, the surgical treatment of hernia and of pneumonectomy (removal of the lungs). Career Macewen was born near Port Bannatyne, near Rothesay on the Isle of Bute, in western Scotland in 1848. He studied Medicine at the University of Glasgow, receiving a medical degree in 1872. He was greatly influenced by Joseph, Lord Lister (1827–1912), who revolutionised surgery by developing antisepsis, by the use of phenol, thus decreasing drastically the enormous mortality of surgical patients due to infections. By following Lister and adopting systematically the use of scrubbing (deep cleansing and disinfection of hands and arms), sterilisation of surgical tools, use of surgical gowns, and (recently discovered) anaesthesia, Macewen became one of the most innovati ...

Scottish People
Scottish people or Scots (; ) are an ethnic group and nation native to Scotland. Historically, they emerged in the Scotland in the Early Middle Ages, early Middle Ages from an amalgamation of two Celtic peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or ''Kingdom of Alba, Alba'') in the 9th century. In the following two centuries, Celtic-speaking Hen Ogledd, Cumbrians of Kingdom of Strathclyde, Strathclyde and Germanic-speaking Anglo-Saxons, Angles of Northumbria became part of Scotland. In the Scotland in the High Middle Ages, High Middle Ages, during the 12th-century Davidian Revolution, small numbers of Normans, Norman nobles migrated to the Lowlands. In the 13th century, the Norse-Gaels of the Kingdom of the Isles, Western Isles became part of Scotland, followed by the Norsemen, Norse of the Northern Isles in the 15th century. In modern usage, "Scottish people" or "Scots" refers to anyone whose linguistic, cultural, family ancestral or genetic origin ...

Archiv Für Pathologische Anatomie Und Physiologie Und Für Klinische Medicin
''Virchows Archiv: European Journal of Pathology'' is a monthly peer-reviewed medical journal of all aspects of pathology, especially human pathology. It is published by Springer Science+Business Media and an official publication of the European Society of Pathology. It was established in 1847 by Rudolf Virchow and his friend Benno Reinhardt as the ''Archiv für pathologische Anatomie und Physiologie und für klinische Medicin''. After Virchow's death, it was renamed after him to ''Virchows Archiv für pathologische Anatomie und Physiologie und für klinische Medizin''. The European Society of Pathology adopted it as its official journal in 1999, so that its current name became ''Virchows Archiv: European Journal of Pathology''. Origin and history In 1846, Rudolf Virchow earned his medical license, and succeeded Robert Froriep as prosector at the Charité Hospital in Berlin. In 1847 he became "privatdozent". However, he soon found that his technical manuscripts were constantly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spleen
The spleen (, from Ancient Greek '' σπλήν'', splḗn) is an organ (biology), organ found in almost all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter. The spleen plays important roles in regard to red blood cells (erythrocytes) and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in case of Shock (circulatory), hemorrhagic shock, and also Human iron metabolism, recycles iron. As a part of the mononuclear phagocyte system, it metabolizes hemoglobin removed from senescent red blood cells. The globin portion of hemoglobin is degraded to its constitutive amino acids, and the heme portion is metabolized to bilirubin, which is removed in the liver. The spleen houses antibody-producing lymphocytes in its white pulp and monocytes which remove antibody-coated bacteria and antibody-coated blood cells by way of blood and lymph node circulation. These monocytes, upon moving to injured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peyer's Patch
Peyer's patches or aggregated lymphoid nodules are organized lymphoid follicles, named after the 17th-century Swiss anatomist Johann Conrad Peyer. * Reprinted as: * Peyer referred to Peyer's patches as ''plexus'' or ''agmina glandularum'' (clusters of glands). From (Peyer, 1681), p. 7: ''"Tenui a perfectiorum animalium Intestina accuratius perlustranti, crebra hinc inde, variis intervallis, corpusculorum glandulosorum Agmina sive Plexus se produnt, diversae Magnitudinis atque Figurae."'' (I knew from careful study of more advanced animals, the intestines bear — often here and there, at various intervals — clusters of glandular small bodies or "plexuses" of diverse size and shape.) From p. 15: ''"(has Plexus seu agmina Glandularum voco)"'' (I call them "plexuses" or clusters of glands) He described their appearance. From p. 8: ''"Horum vero Plexuum facies modo in orbem concinnata; modo in Ovi aut Olivae oblongam, aliamve angulosam ac magis anomalam disposita figuram cern ...

Salmonella
''Salmonella'' is a genus of bacillus (shape), rod-shaped, (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two known species of ''Salmonella'' are ''Salmonella enterica'' and ''Salmonella bongori''. ''S. enterica'' is the type species and is further divided into six subspecies that include over 2,650 serotypes. ''Salmonella'' was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon. ''Salmonella'' species are non-Endospore, spore-forming, predominantly motility, motile enterobacteriaceae, enterobacteria with cell diameters between about 0.7 and 1.5 micrometre, μm, lengths from 2 to 5 μm, and peritrichous flagella (all around the cell body, allowing them to move). They are chemotrophs, obtaining their energy from Redox, oxidation and reduction reactions, using organic sources. They are also facultative aerobic organism, facultative anaerobes, capable of generating adenosine triphosphate with oxygen ("aerobically") ...

Karl Joseph Eberth
Karl Joseph Eberth (21 September 1835 – 2 December 1926) was a German pathologist and bacteriologist who was a native of Würzburg. Biography In 1859 he earned his doctorate at the University of Würzburg, and became an assistant to anatomist Albert von Kölliker (1817–1905). In 1869 he became a full professor of pathological anatomy at the University of Zurich, and from 1881 until his retirement in 1911, he was a professor at the University of Halle. In 1880 Eberth described a bacillus that he suspected was the cause of typhoid. In 1884 pathologist Georg Theodor August Gaffky (1850–1918) confirmed Eberth's findings, and the organism was given names such as "Eberthella typhi", "Eberth's bacillus" and "Gaffky-Eberth bacillus". Today the bacillus that causes typhoid fever goes by the scientific name of ''Salmonella enterica'' subspecies ''enterica'' serovar Typhi. Associated eponyms * "Eberth's lines": Microscopic lines that appear between the cells of the myocardium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
