Generalized Hyperhidrosis
Hyperhidrosis is a medical condition in which a person exhibits excessive sweating, more than is required for the regulation of body temperature. Although it is primarily a physical burden, hyperhidrosis can deteriorate the quality of life of the people who are affected, frequently leading to psychological, physical, and social consequences. Hyperhidrosis can lead to difficulties in professional fields, with more than 80% of patients experiencing moderate to severe emotional effects from the disease. This excess of sweat happens even if the person is not engaging in tasks that require muscular effort, and it does not depend on the exposure to heat. Common places to sweat can include underarms, face, neck, back, groin, feet, and hands. It has been called by some researchers 'the silent handicap'. Both ''diaphoresis'' and ''hidrosis'' can mean either ''perspiration'' (in which sense they are synonymous with ''sweating'') or ''excessive perspiration'', in which case they refer to a ...

Dermatology
Dermatology is the branch of medicine dealing with the Human skin, skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A List of dermatologists, dermatologist is a specialist medical doctor who manages diseases related to skin. Etymology Attested in English in 1819, the word "dermatology" derives from the Ancient Greek, Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία ''wikt:-logia, -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases (Jean-Louis-Marc Alibert, Alibert's, 1806–1816) appeared in print around the same time.Freedber ...

Food
Food is any substance consumed by an organism for Nutrient, nutritional support. Food is usually of plant, animal, or Fungus, fungal origin and contains essential nutrients such as carbohydrates, fats, protein (nutrient), proteins, vitamins, or Mineral (nutrient), minerals. The substance is Ingestion, ingested by an organism and assimilated by the organism's Cell (biology), cells to provide energy, maintain life, or stimulate growth. Different species of animals have different List of feeding behaviours, feeding behaviours that satisfy the needs of their metabolisms and have evolved to fill a specific ecological niche within specific geographical contexts. Omnivore, Omnivorous humans are highly adaptable and have adapted to obtaining food in many different ecosystems. Humans generally use cooking to prepare food for consumption. The majority of the food energy required is supplied by the industrial food industry, which produces food through Intensive farming, intensive agricu ...

Causalgia
Complex regional pain syndrome (CRPS type 1 and type 2), sometimes referred to by the hyponyms reflex sympathetic dystrophy (RSD) or reflex neurovascular dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms. Although it can vary widely, the classic presentation occurs when severe pain from a physical trauma or neurotropic viral infection outlasts the expected recovery time, and may subsequently spread to uninjured areas. The symptoms of types 1 and 2 are the same, except type 2 is associated with nerve injury. Usually starting in a single limb, CRPS often first manifests as pain, swelling, limited range of motion, or partial paralysis, and/or changes to the skin and bones. It may initially affect one limb and then spread throughout the body; 35% of affected individuals report symptoms throughout the body. Two types are thought to exist: CRPS type 1 (previously referred to as '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trench Foot
Trench foot, also known by #Names, other names, is a type of immersion foot syndromes, foot damage due to moisture. Initial symptoms often include tingling or itching which can progress to numbness. The feet may become erythema, red or cyanosis, bluish in color. As the condition worsens the feet can start to swell and smell of decay. Complications may include skin breakdown or infection. Trench foot occurs due to prolonged exposure of the feet to cold, damp, and often unsanitary conditions. Unlike frostbite, trench foot usually occurs at temperatures above freezing, and can be classed as a form of non-freezing cold injury. Onset can be as rapid as 10 hours. Risk factors include overly tight boots and not moving. The underlying mechanism is believed to involve vasoconstriction, constriction of blood vessels resulting in insufficient blood flow to the feet. Diagnosis is based on symptoms and physical examination, examination. Prevention involves keeping the feet warm, dry, and c ...

Burning Feet Syndrome
Burning feet syndrome, also known as Grierson-Gopalan syndrome, is a medical condition that causes severe burning and aching of the feet, hyperesthesia, and vasomotor changes of the feet that lead to excessive sweating. It can even affect the eyes, causing scotoma and amblyopia. The condition occurs more frequently in women, and usually manifests itself when a person is between twenty and forty years old. Presentation The burning heat is usually limited to the soles of the feet, but may extend up to the ankles or lower legs of some patients. The burning can sometimes be accompanied by feelings of 'pins and needles' or tingling in these regions. Nighttime is when almost all people with this syndrome report the heat symptoms being the worst, with the condition getting better as morning comes. Those who have psychosomatic disorders sometimes display psychological symptoms along with the burning of feet associated with the syndrome. For most, there is no redness of the skin of their f ...

POEMS Syndrome
POEMS syndrome (also termed osteosclerotic myeloma, Crow–Fukase syndrome, Takatsuki disease, or PEP syndrome) is a rare paraneoplastic syndrome caused by a clone of aberrant plasma cells. The name POEMS is an acronym for some of the disease's major signs and symptoms (polyneuropathy, polyneuropathy, organomegaly, organomegaly, endocrinopathy, endocrinopathy, myeloma protein, myeloma protein, and cutaneous condition, skin changes), as is PEP (polyneuropathy, polyneuropathy, endocrinopathy, endocrinopathy, plasma cell dyscrasia, plasma cell dyscrasia). The signs and symptoms of most neoplasms (excessive, abnormal tissue growths) are due to their Mass effect (medicine), mass effects (compression of surrounding tissue by the mass of the growth) caused by the invasion and destruction of tissues by the neoplasms' cells. Signs and symptoms of a cancer causing a paraneoplastic syndrome result from the release of humoral factors such as hormones, cytokines, or immunoglobulins by the ...

Glomus Tumor
:''Glomus tumor was also the name formerly (and incorrectly) used for a tumor now called a paraganglioma.'' A glomus tumor (also known as a "solitary glomus tumor") is a rare neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). McGraw-Hill. . They account for less than 2% of all soft tissue tumors. The majority of glomus tumors are benign, but they can also show malignant features. Glomus tumors were first described by Hoyer in 1877 while the first complete clinical description was given by Masson in 1924. Histologically, glomus tumors are made up of an afferent arteriole, anastomotic vessel, and collecting venule. Glomus tumors are modified smooth muscle cells that control the thermoregulatory function of dermal glomus bodies. As stated above, these lesions should not be confused with paragangliomas, which were formerly also called glomus tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Rubber Bleb Nevus
Blue rubber bleb nevus syndrome is a rare disorder that consists mainly of abnormal blood vessels affecting the skin or internal organs – usually the gastrointestinal tract. The disease is characterized by the presence of fluid-filled blisters ( blebs) as visible, circumscribed, chronic lesions ( nevi). BRBNS is caused by somatic mutations in the TEK (TIE2) gene. It was described by William Bennett Bean in 1958. Presentation BRBNS is a venous malformation, formerly, though incorrectly, thought to be related to the hemangioma. It sometimes causes serious bleeding. Lesions are most commonly found on the skin and in the small intestine and distal large bowel. The lesions can also be found in the central nervous system, liver, and muscles. It usually presents soon after birth or during early infancy. Causes The cause of blue rubber bleb nevus syndrome is currently unknown. The syndrome is considered sporadic. A patient who is diagnosed with BRBNS likely has a family history ...

Infection
An infection is the invasion of tissue (biology), tissues by pathogens, their multiplication, and the reaction of host (biology), host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an Disease#Terminology, illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently pathogenic bacteria, bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an Innate immune system, innate response, often involving inflammation, followed by an Adaptive immune system, adaptive response. Treatment for infections depends on the type of pathogen involved. Common medications include: * Antibiotics for bacterial infections. * Antivirals for viral infections. * Antifungals for fungal infections. * Antiprotozoals for protozoan infections. * Antihelminthics for infections caused by parasi ...

Endocrine System
The endocrine system is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant Organ (biology), organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland, thyroid, parathyroid gland, parathyroid, pituitary gland, pituitary, pineal gland, pineal, and adrenal glands, and the (male) testis and (female) ovaries. The hypothalamus, pancreas, and thymus also function as endocrine glands, among other functions. (The hypothalamus and pituitary glands are organs of the Neuroendocrinology#Neuroendocrine system, neuroendocrine system. One of the most important functions of the hypothalamusit is located in the brain adjacent to the pituitary glandis to link the endocrine system to the nervous system via the pituitary gland.) Other organs, such as the kidneys, also have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cancer
Cancer is a group of diseases involving Cell growth#Disorders, abnormal cell growth with the potential to Invasion (cancer), invade or Metastasis, spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible Signs and symptoms of cancer, signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in defecation, bowel movements. While these symptoms may indicate cancer, they can also have other causes. List of cancer types, Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor Diet (nutrition), diet, sedentary lifestyle, lack of physical activity or Alcohol abuse, excessive alcohol consumption. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. infectious causes of cancer, Infection with specific viruses, bacteria and parasites is an environmental factor cau ...

Odor
An odor (American English) or odour ( Commonwealth English; see spelling differences) is a smell or a scent caused by one or more volatilized chemical compounds generally found in low concentrations that humans and many animals can perceive via their olfactory system. While ''smell'' can refer to pleasant and unpleasant odors, the terms ''scent'', ''aroma'', and ''fragrance'' are usually reserved for pleasant-smelling odors and are frequently used in the food and cosmetic industry to describe floral scents or to refer to perfumes. Odor physiology Sense of smell The perception of odors, or sense of smell, is mediated by the olfactory nerve. The olfactory receptor (OR) cells are neurons present in the olfactory epithelium, which is a small patch of tissue at the back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. Each neuron has cilia in direct contact with the air. Odorous molecules bind to receptor pro ...
