Benign Symmetric Lipomatosis
Benign symmetric lipomatosis is a skin condition characterized by extensive symmetric fat deposits in the head, neck, and shoulder girdle area. The German surgeon Otto Wilhelm Madelung was the first to give a detailed description of the disorder. This condition is very rare, with an estimated incidence of 1 in 25,000, and affects males up to 30 times more frequently than females. Cause The cause of the disease remains unknown, but its incidence strongly correlates with alcohol use disorder; abstinence from alcohol prevents disease progression. Defects in the adrenergic-stimulated lipolysis and accumulation of embryological brown fat have also been reported. Cosmetic disfigurement due to the fat deposition in the cervicothoracic region results in a "pseudoathletic appearance", resembling the Italian statue ''Warrior of Capestrano'' and carvings of Queen of Punt (Egypt). Treatment Traditionally the treatment is mainly surgical, consisting of the removal of the lipomas, although rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Wilhelm Madelung
Otto Wilhelm Madelung (May 15, 1846 – July 22, 1926) was a German surgeon who was a native of Gotha Gotha () is the fifth-largest city in Thuringia, Germany, west of Erfurt and east of Eisenach with a population of 44,000. The city is the capital of the district of Gotha and was also a residence of the Ernestine Wettins from 1640 until the .... His son, physicist Erwin Madelung (1881–1972), discovered the Madelung constant. Academic career Madelung was born in Gotha. In 1869 he received his medical doctorate from the University of Tübingen, afterwards being assigned to a military hospital during the Franco-Prussian War. He later served as a surgical assistant in Bonn, and in 1873–74 worked as an assistant at the pathology, pathological clinic of Eduard von Rindfleisch, Georg Eduard von Rindfleisch (1836–1908). In 1874 he visited Great Britain and the United States. In 1881 he became an assistant professor of surgery at the University of Bonn, followed by profe ...

Incidence (epidemiology)
In epidemiology, incidence is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. Although sometimes loosely expressed simply as the number of new cases during some time period, it is better expressed as a proportion or a rate with a denominator. Incidence proportion Incidence proportion (IP), also known as cumulative incidence, is defined as the probability that a particular event, such as occurrence of a particular disease, has occurred before a given time. It is calculated dividing the number of new cases during a given period by the number of subjects at risk in the population initially at risk at the beginning of the study. Where the period of time considered is an entire lifetime, the incidence proportion is called lifetime risk. For example, if a population initially contains 1,000 persons and 28 develop a condition since the disease first occurred until two years later, the cumulative incidence prop ...

Alcoholism
Alcoholism is, broadly, any drinking of alcohol (drug), alcohol that results in significant Mental health, mental or physical health problems. Because there is disagreement on the definition of the word ''alcoholism'', it is not a recognized diagnostic entity. Predominant diagnostic classifications are alcohol use disorder (DSM-5) or alcohol dependence (ICD-11); these are defined in their respective sources. Excessive alcohol use can damage all organ systems, but it particularly affects the brain, heart, liver, pancreas and immune system. Alcoholism can result in mental illness, delirium tremens, Wernicke–Korsakoff syndrome, Heart arrhythmia, irregular heartbeat, an impaired immune response, liver cirrhosis and alcohol and cancer, increased cancer risk. Drinking during pregnancy can result in fetal alcohol spectrum disorders. Women are generally more sensitive than men to the harmful effects of alcohol, primarily due to their smaller body weight, lower capacity to metaboli ...

Lipolysis
Lipolysis is the metabolic pathway through which lipid triglycerides are hydrolyzed into a glycerol and free fatty acids. It is used to mobilize stored energy during fasting or exercise, and usually occurs in fat adipocytes. The most important regulatory hormone in lipolysis is insulin; lipolysis can only occur when insulin action falls to low levels, as occurs during fasting. Other hormones that affect lipolysis include glucagon, epinephrine, norepinephrine, growth hormone, atrial natriuretic peptide, brain natriuretic peptide, and cortisol. Mechanisms In the body, stores of fat are referred to as adipose tissue. In these areas, intracellular triglycerides are stored in cytoplasmic lipid droplets. When lipase enzymes are phosphorylated, they can access lipid droplets and through multiple steps of hydrolysis, breakdown triglycerides into fatty acids and glycerol. Each step of hydrolysis leads to the removal of one fatty acid. The first step and the rate-limiting step of l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Adipose Tissue
Brown adipose tissue (BAT) or brown fat makes up the adipose organ together with white adipose tissue (or white fat). Brown adipose tissue is found in almost all mammals. Classification of brown fat refers to two distinct cell populations with similar functions. The first shares a common embryological origin with muscle cells, found in larger "classic" deposits. The second develops from white adipocytes that are stimulated by the sympathetic nervous system. These adipocytes are found interspersed in white adipose tissue and are also named 'beige' or 'brite' (for "brown in white"). Brown adipose tissue is especially abundant in newborns and in hibernating mammals. It is also present and metabolically active in adult humans, but its prevalence decreases as humans age. Its primary function is thermoregulation. In addition to heat produced by shivering muscle, brown adipose tissue produces heat by non-shivering thermogenesis. The therapeutic targeting of brown fat for the treatment o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warrior Of Capestrano
''The Warrior of Capestrano'' is a tall limestone statue of a Picene warrior, dated to around the 6th century BC. The statue stands at around 2.09 m. It was discovered accidentally in 1934 by a laborer ploughing the field in the Italian town of Capestrano, along with a female statue in civilian attire, called '' Lady of Capestrano''. Description The Capestrano Warrior is a piece of Italic art dating back to the 6th Century BCE. At first, archaeologists and historians thought these statues depicted members of a powerful Italic family. It is made of limestone, and it stands on a base made of lithic. Two pillars were used to laterally frame the statue. It depicts a man wearing a brassard and carrying weapons and armor. He is wearing a wide-brimmed parade helmet with a crest of feathers. Between the kardiophylax lied a long sword and a knife. It also wears a ''mitra,'' which was a short apron covering the back. It had a black plate with a broad hinged band. Anthropomorphic an ...

Shesmetet
Shesmetet ''(šsm.t.t)'' is an ancient Egyptian goddess. She was mentioned in the Pyramid Texts''Pyramid Texts'' 262, 2206 and was usually referred to as the deceased's mother. She was depicted as a lion or a woman with a lion's head, and thus was sometimes considered a form of Sekhmet or Bastet, but one of her epithets – "Lady of Punt" – differentiates her from them and may refer to a possible African origin. Her name comes from ''shesmet,'' a sash decorated with beads, which appears on the depictions of Old Kingdom rulers and the god Sopdu Sopdu (also rendered Septu or Sopedu) was a god of the sky and of eastern border regions in the religion of Ancient Egypt.Wilkinson, Richard H.

Phosphatidylcholine
Phosphatidylcholines (PC) are a class of phospholipids that incorporate choline as a headgroup. They are a major component of biological membranes and can be easily obtained from a variety of readily available sources, such as egg yolk or soybeans, from which they are mechanically or chemically extracted using hexane. They are also a member of the lecithin group of yellow-brownish fatty substances occurring in animal and plant tissues. Dipalmitoyl phosphatidylcholine (a.k.a. lecithin) is a major component of pulmonary surfactant and is often used in the L/S ratio to calculate fetal lung maturity. While phosphatidylcholines are found in all plant and animal cells, they are absent in the membranes of most bacteria, including ''Escherichia coli''. Purified phosphatidylcholine is produced commercially. The name ''lecithin'' was derived from Greek λέκιθος, ''lekithos'' 'egg yolk' by Theodore Nicolas Gobley, a French chemist and pharmacist of the mid-19th century, who appli ...

Lipomatosis
Lipomatosis is believed to be an autosomal dominant condition in which multiple lipomas are present on the body. Many discrete, encapsulated lipomas form on the trunk and extremities, with relatively few on the head and shoulders. In 1993, a genetic polymorphism within lipomas was localized to chromosome 12q15, where the HMGIC gene encodes the high-mobility-group protein isoform I-C. This is one of the most commonly found mutations in solitary lipomatous tumors but lipomas often have multiple mutations. Reciprocal translocations involving chromosomes 12q13 and 12q14 have also been observed within. Although this condition is benign, it can sometimes be very painful depending on location of the lipomas. Some patients who are concerned with cosmetics seek removal of individual lipomas. Removal can include simple excision, endoscopic removal, or liposuction. Other entities which are accompanied by multiple lipomas include Proteus syndrome, Cowden syndrome and related disorders due ...

List Of Skin Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm that ...
