Hypochromic Anemia
Hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. (''Hypo''- refers to ''less'', and ''chromic'' means ''colour''.) A normal red blood cell has a biconcave disk shape and will have an area of pallor in its center when viewed microscopically. In hypochromic cells, this area of central pallor is increased. This decrease in redness is due to a disproportionate reduction of red cell hemoglobin (the pigment that imparts the red color) in proportion to the volume of the cell. Clinically the color can be evaluated by the mean corpuscular hemoglobin (MCH) or mean corpuscular hemoglobin concentration (MCHC). The MCHC is considered the better parameter of the two as it adjusts for effect the size of the cell has on its amount of hemoglobin. Hypochromia is clinically defined as below the normal MCH reference range of 27–33 picograms/cell in adults or below the normal MCHC reference range of 33–36 g/dL in adults. Red blood cells ...

Montpellier
Montpellier (; ) is a city in southern France near the Mediterranean Sea. One of the largest urban centres in the region of Occitania (administrative region), Occitania, Montpellier is the prefecture of the Departments of France, department of Hérault.

Pica (disorder)
Pica ("PIE-kuh"; IPA: /ˈpaɪkə/) is the craving or consumption of objects that are not normally intended to be consumed. It is classified as an eating disorder but can also be the result of an existing mental disorder. The ingested or craved substance may be biological, natural, or manmade. The term was drawn directly from the medieval Latin word for magpie, a bird subject to much folklore regarding its opportunistic feeding behaviors. According to the '' Diagnostic and Statistical Manual of Mental Disorders, 5th Edition'' (DSM-5), pica as a standalone eating disorder must persist for more than one month at an age when eating such objects is considered developmentally inappropriate, not part of culturally sanctioned practice, and sufficiently severe to warrant clinical attention. Pica may lead to intoxication in children, which can result in an impairment of both physical and mental development. In addition, it can cause surgical emergencies to address intestinal obstruction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viscus
In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which has a specific function. The intestinal wall for example is formed by epithelial tissue and smooth muscle tissue. Two or more organs working together in the execution of a specific body function form an organ system, also called a biological system or body system. An organ's tissues can be broadly categorized as parenchyma, the functional tissue, and stroma, the structural tissue with supportive, connective, or ancillary functions. For example, the gland's tissue that makes the hormones is the parenchyma, whereas the stroma includes the nerves that innervate the parenchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wa ...

Menstruation
Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and Mucous membrane, mucosal tissue from the endometrium, inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels, and is a sign that pregnancy has not occurred. Women use feminine hygiene products to maintain hygiene during menses. The first period, a point in time known as menarche, usually begins during puberty, between the ages of 11 and 13. However, menstruation starting as young as 8 years would still be considered normal. The average age of the first period is generally later in the developing world, and earlier in the developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women; in adults, the range is between 21 and 35 days with the average often cited as 28 days.

Daniel Turner (physician)
Daniel Turner (18 September 1667 – 13 March 1740/41) was a London physician who published the first textbook on dermatology in English. ''De Morbis Cutaneis'' was first published in 1714 and went through several English editions. It was also published in French and German. Turner started his medical career as a barber surgeon. In 1723 he was awarded a Doctor of Medicine (abbreviated M.D.) by Yale College Yale College is the undergraduate college of Yale University. Founded in 1701, it is the original school of the university. Although other Yale schools were founded as early as 1810, all of Yale was officially known as Yale College until 1887, ..., the first ever D.M. awarded by the US college.

Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Consumption (disease)
Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, is a contagious disease usually caused by ''Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as inactive or latent tuberculosis. A small proportion of latent infections progress to active disease that, if left untreated, can be fatal. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with latent TB do not spread the disease. A latent infection is more likely to become active in those with weakened immune systems. There are two principal tests for TB: inte ...

Hysteria
Hysteria is a term used to mean ungovernable emotional excess and can refer to a temporary state of mind or emotion. In the nineteenth century, female hysteria was considered a diagnosable physical illness in women. It is assumed that the basis for diagnosis operated under the belief that women are predisposed to mental and behavioral conditions; an interpretation of sex-related differences in stress responses. In the twentieth century, it shifted to being considered a mental illness. Influential physicians the likes of Sigmund Freud and Jean-Martin Charcot had dedicated research to hysteria patients. Currently, most physicians do not accept hysteria as a medical diagnosis. The blanket diagnosis of hysteria has been fragmented into myriad medical categories such as epilepsy, histrionic personality disorder, conversion disorders, dissociative disorders, or other medical conditions. Furthermore, lifestyle choices, such as choosing not to wed, are no longer considered symptom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Sydenham
Thomas Sydenham (; 10 September 1624 – 29 December 1689) was an England, English physician. He was the author of ''Observationes Medicae'' (1676) which became a standard textbook of medicine for two centuries so that he became known as 'The English Hippocrates'. Among his many achievements was the discovery of a disease, Sydenham's chorea, also known as St Vitus' Dance. To him is attributed the prescient dictum, "A man is as old as his arteries." Early life Thomas Sydenham was born at Wynford Eagle in Dorset, where his father was a gentleman of property. His brother was Colonel William Sydenham. At the age of eighteen Sydenham attended Magdalen Hall, Oxford; after a short period his college studies appear to have been interrupted, and he served for a time as an officer in the Parliamentarian army during the Civil War. He completed his Oxford course in 1648, graduating as bachelor of medicine, and about the same time he was elected a fellow of All Souls College, Oxford, All ...

Celibacy
Celibacy (from Latin ''caelibatus'') is the state of voluntarily being unmarried, sexually abstinent, or both. It is often in association with the role of a religious official or devotee. In its narrow sense, the term ''celibacy'' is applied only to those for whom the unmarried state is the result of a sacred vow, act of renunciation, or religious conviction. In a wider sense, it is commonly understood to only mean abstinence from sexual activity. Celibacy has existed in one form or another throughout history, in virtually all the major religions of the world, and views on it have varied. Classical Hindu culture encouraged asceticism and celibacy in the later stages of life, after one has met one's societal obligations. Jainism, on the other hand, preached complete celibacy even for young monks and considered celibacy to be an essential behavior to attain moksha. Buddhism is similar to Jainism in this respect. There were, however, significant cultural differences in the va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
