Cauterization
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable. The practice was once widespread for treatment of wounds. Its utility before the advent of antibiotics was said to be effective at more than one level: *To prevent exsanguination *To close amputations Cautery was historically believed to prevent infection, but current research shows that cautery actually increases the risk for infection by causing more tissue damage and providing a more hospitable environment for bacterial growth. Actual cautery refers to the metal device, generally heated to a dull red glow, that a physician applies to produce blisters, to stop bleeding of a blood vessel, and for other similar purposes., page 16. The main forms ...

Nosebleed
A nosebleed, also known as epistaxis, is bleeding from the nose. Blood can flow down into the stomach, and cause nausea and vomiting. In more severe cases, blood may come out of both nostrils. Rarely, bleeding may be so significant that low blood pressure occurs. Blood may also come up the nasolacrimal duct and out from the eye. Risk factors include trauma, including putting the finger in the nose, blood thinners, high blood pressure, alcoholism, seasonal allergies, dry weather, and inhaled corticosteroids. There are two types: anterior, which is more common; and posterior, which is less common but more serious. Anterior nosebleeds generally occur from Kiesselbach's plexus while posterior bleeds generally occur from the sphenopalatine artery. The diagnosis is by direct observation. Prevention may include the use of petroleum jelly in the nose. Initially, treatment is generally the application of pressure for at least five minutes over the lower half of the nose. If this is n ...

Human Branding
Human branding or stigmatizing is the process by which a mark, usually a symbol or ornamental pattern, is burned into the skin of a living person, with the intention that the resulting scar makes it permanent. This is performed using a hot or very cold branding iron. It therefore uses the physical techniques of livestock branding on a human, either with consent as a form of body modification; or under coercion, as a punishment or to identify an enslaved, oppressed, or otherwise controlled person. It may also be practiced as a "rite of passage", e.g. within a tribe, or to signify membership of or acceptance into an organization. Etymology The English verb to ''burn'', attested since the 12th century, is a combination of Old Norse ''brenna'' "to burn, light", and two originally distinct Old English verbs: ''bærnan'' "to kindle" (transitive) and ''beornan'' "to be on fire" (intransitive), both from the Proto-Germanic root ''bren(wanan)'', perhaps from a Proto-Indo-European root ' ...

Burn (injury)
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ultraviolet radiation (like sunburn). Most burns are due to heat from hot liquids (called scalding), solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault). Burns that affect only the superficial skin layers are known as superficial or first-degree burns. They appear red without blisters and pain typically lasts around three days. When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. Blisters are frequently present and they are often very painful. Healing can require up to eight weeks and scarr ...

Pre-Islamic Arabia
Pre-Islamic Arabia ( ar, شبه الجزيرة العربية قبل الإسلام) refers to the Arabian Peninsula before the History of Islam, emergence of Islam in 610 CE. Some of the settled communities developed into distinctive civilizations. Information about these communities is limited and has been pieced together from archaeological evidence, accounts written outside of Arabia, and Arab oral traditions which were later recorded by List of Muslim historians, Islamic historians. Among the most prominent civilizations were the Thamud civilization, which arose around 3000 BCE and lasted to around 300 CE, and the earliest Semitic civilization in the eastern part was Dilmun, which arose around the end of the fourth millennium and lasted to around 600 CE. Additionally, from the second half of the second millennium BCE,Kenneth A. Kitchen The World of "Ancient Arabia" Series. Documentation for Ancient Arabia. Part I.

Muslim World
The terms Muslim world and Islamic world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense. The history of the Muslim world spans about 1,400 years and includes a variety of socio-political developments, as well as advances in the arts, science, medicine, philosophy, law, economics and technology, particularly during the Islamic Golden Age. All Muslims look for guidance to the Quran and believe in the prophetic mission of the Islamic prophet Muhammad, but disagreements on other matters have led to the appearance of different religious schools of thought and sects within Islam. In the modern era, mos ...

Al-Zahrawi
Abū al-Qāsim Khalaf ibn al-'Abbās al-Zahrāwī al-Ansari ( ar, أبو القاسم خلف بن العباس الزهراوي;‎ 936–1013), popularly known as al-Zahrawi (), Latinised as Albucasis (from Arabic ''Abū al-Qāsim''), was an Arab Andalusian physician, surgeon and chemist."Al-Zahrawi's ancestry then, one might infer, goes back to the Arabian Peninsula, to the inhabitants of "al-Madinah," the first city that accepted the message of Islam." Considered to be the greatest surgeon of the Middle Ages, he has been referred to as the "father of modern surgery". Al-Zahrawi's principal work is the ''Kitab al-Tasrif'', a thirty-volume encyclopedia of medical practices. The surgery chapter of this work was later translated into Latin, attaining popularity and becoming the standard textbook in Europe for the next five hundred years. Al-Zahrawi's pioneering contributions to the field of surgical procedures and instruments had an enormous impact in the East and West well ...

Ligature (medicine)
In surgery or medical procedure, a ligature consists of a piece of thread ( suture) tied around an anatomical structure, usually a blood vessel or another hollow structure (e.g. urethra) to shut it off. History The principle of ligation is attributed to Hippocrates and Galen. In ancient Rome, ligatures were used to treat hemorrhoids. The concept of a ligature was reintroduced some 1,500 years later by Ambroise Paré, and finally it found its modern use in 1870–80, made popular by Jules-Émile Péan. Procedure With a blood vessel the surgeon will clamp the vessel perpendicular to the axis of the artery or vein with a hemostat, then secure it by ligating it; i.e. using a piece of suture around it before dividing the structure and releasing the hemostat. It is different from a tourniquet in that the tourniquet will not be secured by knots and it can therefore be released/tightened at will. Ligature is one of the remedies to treat skin tag, or acrochorda. It is done by tying str ...

Ambroise Paré
Ambroise Paré (c. 1510 – 20 December 1590) was a French barber surgeon who served in that role for kings Henry II, Francis II, Charles IX and Henry III. He is considered one of the fathers of surgery and modern forensic pathology and a pioneer in surgical techniques and battlefield medicine, especially in the treatment of wounds. He was also an anatomist, invented several surgical instruments, and was a member of the Parisian barber surgeon guild. In his personal notes about the care he delivered to Captain Rat, in the Piémont campaign (1537–1538), Paré wrote: ''Je le pansai, Dieu le guérit'' ("I bandaged him and God healed him"). This epitomises a philosophy that he used throughout his career. These words, inscribed on his statue in Laval, are reminiscent of the Latin adage '' medicus curat, natura sanat''. Early life Paré was born in 1510 in Bourg-Hersent, near Laval, then part of the province of Maine, in northwestern France. As a child he watched, and was fir ...

Huangdi Neijing
''Huangdi Neijing'' (), literally the ''Inner Canon of the Yellow Emperor'' or ''Esoteric Scripture of the Yellow Emperor'', is an ancient Chinese medical text or group of texts that has been treated as a fundamental doctrinal source for Chinese medicine for more than two millennia. The work comprises two texts—each of eighty-one chapters or treatises in a question-and-answer format between the mythical Yellow Emperor and six of his equally legendary ministers. The first text, the ''Suwen'' (), also known as ''Basic Questions'', covers the theoretical foundation of Chinese Medicine and its diagnostic methods. The second and generally less referred-to text, the '' Lingshu'' (; ''Spiritual Pivot''), discusses acupuncture therapy in great detail. Collectively, these two texts are known as the ''Neijing'' or ''Huangdi Neijing.'' In practice, however, the title ''Neijing'' often refers only to the more influential ''Suwen''. Two other texts also carried the prefix ''Huangdi Nei ...

Heat Conduction
Conduction is the process by which heat is transferred from the hotter end to the colder end of an object. The ability of the object to conduct heat is known as its ''thermal conductivity'', and is denoted . Heat spontaneously flows along a temperature gradient (i.e. from a hotter body to a colder body). For example, heat is conducted from the hotplate of an electric stove to the bottom of a saucepan in contact with it. In the absence of an opposing external driving energy source, within a body or between bodies, temperature differences decay over time, and thermal equilibrium is approached, temperature becoming more uniform. In conduction, the heat flow is within and through the body itself. In contrast, in heat transfer by thermal radiation, the transfer is often between bodies, which may be separated spatially. Heat can also be transferred by a combination of conduction and radiation. In solids, conduction is mediated by the combination of vibrations and collisions of molecu ...
