Tinea Corporis
Tinea corporis is a fungal infection of the body, similar to other forms of tinea. Specifically, it is a type of dermatophytosis (or ringworm) that appears on the arms and legs, especially on glabrous skin; however, it may occur on any superficial part of the body. Signs and symptoms It may have a variety of appearances; most easily identifiable are the enlarging raised red rings with a central area of clearing (ringworm). The same appearances of ringworm may also occur on the scalp (tinea capitis), beard area ( tinea barbae) or the groin ( tinea cruris, known as jock itch or dhobi itch). Other classic features of tinea corporis include: * Itching occurs on infected area. * The edge of the rash appears elevated and is scaly to touch. * Sometimes the skin surrounding the rash may be dry and flaky. * Almost invariably, there will be hair loss in areas of the infection. Causes Tinea corporis is caused by a tiny fungus known as dermatophyte. These tiny organisms normally live on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rugby Football
Rugby football is the collective name for the team sports of rugby union or rugby league. Rugby football started at Rugby School in Rugby, Warwickshire, England, where the rules were first codified in 1845. Forms of football in which the ball was carried and tossed date to the Middle Ages (see medieval football). Rugby football spread to other Public school (United Kingdom), English public schools in the 19th century and across the British Empire as former pupils continued to play it. Rugby football split into two codes in 1895, when twenty-one clubs from the North of England left the Rugby Football Union to form the Rugby Football League, Northern Rugby Football Union (renamed the Rugby Football League in 1922) at the George Hotel, Huddersfield, George Hotel, Huddersfield, over payments to players who took time off work to play ("broken-time payments"), thus making rugby league the first Football, code to turn professional sport, professional and pay players. Rugby union turn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naftifine
Naftifine hydrochloride (brand names include Exoderil and Naftin) is an allylamine antifungal drug for the topical treatment of tinea pedis, tinea cruris, and tinea corporis (topical fungal infections). Naftifine was invented at the Sandoz Research Institute in Vienna, Austria. It was the first successful antifungal medication of the allylamine class. Naftifine has triple action: antifungal, antibacterial, and anti-inflammatory. Its fungistatic activity is believed to be based on inhibition of the squalene-2,3-epoxidase enzyme, which in turn results in the shortage of ergosterol required for the formation of fungal cell membranes. With some fungal species, there is also fungicidal activity from a resulting accumulation of squalenes, leading to damage of the fungal cell membranes, including at the endoplasmatic reticulum.. Naftifine shows mostly fungicidal activity toward dermatophytes and molds, and mostly fungistatic activity toward yeasts. It is also effective as an antiba ...

Terbinafine
Terbinafine, sold under the brand name Lamisil among others, is an antifungal medication used to treat pityriasis versicolor, onychomycosis, fungal nail infections, and ringworm including jock itch and athlete's foot. It is either oral administration, taken by mouth or applied to the skin as a cream or ointment. Common side effects when taken by mouth include nausea, diarrhea, headache, cough, rash, and elevated liver enzymes. Severe side effects include liver problems and allergic reactions. Liver injury is, however, unusual. Oral use during pregnancy is not typically recommended. The cream and ointment may result in itchiness but are generally well tolerated. Terbinafine is in the allylamines family of medications. It works by decreasing the ability of fungi to synthesize ergosterol. It appears to result in fungicide, fungal cell death. Terbinafine was discovered in 1991. It is on the WHO Model List of Essential Medicines, World Health Organization's List of Essential Medi ...

Prescription Drug
A prescription drug (also prescription medication, prescription medicine or prescription-only medication) is a pharmaceutical drug that is permitted to be dispensed only to those with a medical prescription. In contrast, over-the-counter drugs can be obtained without a prescription. The reason for this difference in substance control is the potential scope of misuse, from drug abuse to practising medicine without a license and without sufficient education. Different jurisdictions have different definitions of what constitutes a prescription drug. In North America, , usually printed as "Rx", is used as an abbreviation of the word "prescription". It is a contraction of the Latin word "''recipe''" (an imperative form of "recipere") meaning "take". Prescription drugs are often dispensed together with a monograph (in Europe, a Patient Information Leaflet or PIL) that gives detailed information about the drug. The use of prescription drugs has been increasing since the 1960s. Regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ketoconazole
Ketoconazole, sold under the brand name Nizoral, among others, is an antiandrogen, antifungal drug, antifungal, and antiglucocorticoid medication used to treat a number of fungal infections. Applied to the skin it is used for fungal skin infections such as tinea, cutaneous candidiasis, pityriasis versicolor, dandruff, and seborrhoeic dermatitis, seborrheic dermatitis. Taken oral administration, by mouth it is a less preferred option and recommended for only severe infections when other agents cannot be used. Other uses include treatment of hirsutism, excessive male-patterned hair growth in women and Cushing's syndrome. Common side effects when transdermal administration, applied to the skin include redness. Common side effects when taken by mouth include nausea, headache, and liver problems. Liver problems may result in death or the need for a liver transplantation. Other severe side effects when taken orally include QT prolongation, adrenocortical insufficiency, and anaphyl ...

Tolnaftate
Tolnaftate (INN), sold under the brand name TAGRID, among others, is a synthetic thiocarbamate used as an anti-fungal agent that may be sold without medical prescription in most jurisdictions. It is supplied as a cream, powder, spray, liquid, and liquid aerosol. Tolnaftate is used to treat fungal conditions such as jock itch, athlete's foot and ringworm. Tolnaftate was discovered by Teruhisa Noguchi in 1962 while he was working for the Nippon Soda Company. Mechanism Although the exact mechanism of action is not entirely known, it is believed to inhibit squalene epoxidase, an important enzyme in the biosynthetic pathway of ergosterol (a key component of the fungal cell membrane) in a similar way to terbinafine. Uses Tolnaftate has been found to be generally slightly less effective than azoles when used to treat tinea pedis (athlete's foot). It is, however, useful when dealing with ringworm, especially when passed from pets to humans.Crawford F, Hart R, Bell-Syer S, Torgerson ...

Over-the-counter Drug
Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a requirement for a prescription from a healthcare professional, as opposed to prescription drugs, which may be supplied only to consumers possessing a valid prescription. In many countries, OTC drugs are selected by a regulatory agency to ensure that they contain ingredients that are safe and effective when used without a physician's care. OTC drugs are usually regulated according to their active pharmaceutical ingredient (API) and strengths of final products. The term ''over-the-counter'' (''OTC'') refers to a medication that can be purchased without a medical prescription. In contrast, prescription drugs require a prescription from a doctor or other health care professional and should only be used by the prescribed individual. Some drugs may be legally classified as over-the-counter (i.e. no prescription is required), but may only be dispensed by a pharmacist after an assessment of the patient ...

KOH Test
The KOH test, also known as a potassium hydroxide preparation or KOH prep, is a quick, inexpensive fungal test to differentiate dermatophytes and ''Candida albicans'' symptoms from other skin disorders like psoriasis and eczema. Dermatophytes are a type of fungus that invades the top layer of the skin, hair, or nails. There are three genera of fungi commonly implicated: ''Trichophyton'' (found in skin, nail, and hair infections), '' Epidermophyton'' (skin and nail infections), and ''Microsporum'' (skin and hair infections). Dermatophytes produce an infection commonly known as ringworm or tinea. It can appear as "jock itch" in the groin or inner thighs (tinea cruris); on the scalp and hair (tinea capitis) resulting in brittle hair shafts that fall out easily. Tinea unguium affects the nails and athlete's foot (tinea pedis) affects the feet. Tinea versicolor refers to a fungal infection of the skin caused by '' Malassezia furfur''. It appears anywhere on the skin and produces red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microscope
A microscope () is a laboratory equipment, laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting fluorescence, photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a microtome, thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence micro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
