Tinea Manuum
Tinea manuum is a fungal infection of the hand, mostly a type of dermatophytosis, often part of two feet-one hand syndrome. There is diffuse scaling on the palms or back of usually one hand and the palmar creases appear more prominent. When both hands are affected, the rash looks different on each hand, with palmar creases appearing whitish if the infection has been present for a long time. It can be itchy and look slightly raised. Nails may also be affected. The most common cause is ''Trichophyton rubrum''. The infection can result from touching another area of the body with a fungal infection such as athlete's foot or tinea cruris, fungal infection of the groin, contact with an infected person or animal, or contact with soil or contaminated towels. Risk factors include diabetes, hypertension, high blood pressure, immunosuppression, weak immune system, humid surroundings, excessive sweating, recurrent hand trauma and cracks in the feet. Pet owners and farmworkers are also at high ... [...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 ...

Tinea Cruris
Tinea cruris (TC), also known as jock itch, is a common type of contagious, superficial fungal infection of the groin and buttocks region, which occurs predominantly but not exclusively in men and in hot-humid climates. Typically, over the upper inner thighs, there is an intensely itchy red raised rash with a scaly well-defined curved border. It is often associated with athlete's foot and fungal nail infections, excessive sweating, and sharing of infected towels or sports clothing. It is uncommon in children. Its appearance may be similar to some other rashes that occur in skin folds including candidal intertrigo, erythrasma, inverse psoriasis and seborrhoeic dermatitis. Tests may include microscopy and culture of skin scrapings. Treatment is with topical antifungal medications and is particularly effective if symptoms have recent onset. Prevention of recurrences include treating concurrent fungal infections and taking measures to avoid moisture build-up including keeping the ...

Trichophyton Interdigitale
''Trichophyton interdigitale'' is a clonal line within sexual species '' T. mentagrophytes''. It causes onychomycosis and tinea pedis Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin (a dermatomycosis), that may affect skin, hair, and nails. Typically it results in a red, itchy, scaly, circular rash. Hair loss may occur in the area aff ... in humans, and has never been isolated from animals. ''Trichophyton interdigitale'' isolates cannot be reliably discriminated from ''T.mentagrophytes'' by cultural techniques or MALDI-TOF mass spectrometry, and therefore ITS region DNA sequencing is recommended. Critics ''Trichophyton interdigitale'' is defined by its capability of transmission between human hosts and clonal way of reproduction. However, there is at least one another anthropophilic clonal line within '' T. mentagrophytes'', phylogenetically unrelated to ''T. interdigitale''.

Epidermophyton Floccosum
''Epidermophyton floccosum'' is a filamentous fungus that causes skin and nail infections in humans. This anthropophilic dermatophyte can lead to diseases such as tinea pedis (athlete's foot), tinea cruris, tinea corporis and onychomycosis. Diagnostic approaches of the fungal infection include physical examination, culture testing, and molecular detection. Topical antifungal treatment, such as the use of terbinafine, itraconazole, voriconazole, and ketoconazole, is often effective. ''E. floccosum'' is one of the 2 species in the genus '' Epidermophyton''. During the 20th century, this species was the fourth most common cause of dermatophytosis in North America. This ascomycete has a worldwide distribution but is more commonly isolated from patients in tropical and subtropical areas. The non-soil associated fungus has no specific growth conditions and shows characteristic smooth club-shaped macroconidia under the microscope. History and taxonomy The fungus was first isolated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trichophyton Mentagrophytes
''Trichophyton mentagrophytes'' is a species in the fungal genus '' Trichophyton''. It is one of three common fungi which cause ringworm in companion animals. It is also the second-most commonly isolated fungus causing tinea infections in humans, and the most common or one of the most common fungi that cause zoonotic skin disease. ''Trichophyton mentagrophytes'' is frequently isolated from dogs, cats, rabbits, guinea pigs and other rodents, though at least some genetic variants possess the potential of human-to-human transmission, e.g. Type VII and Type VIII. As of 2024 it is an emerging STD in men who have sex with men and in sex workers of all genders. Nomenclature Along with closely related '' T. interdigitale'', the species has been traditionally treated as a part of polyphyletic assemblage, named "''T. mentagrophytes'' sensu lato". From 1999 to 2017 the two species have been collectively referred to as ''T. interdigitale'', while the name "''T. mentagrophytes''" has been ...

Trichophyton Erinacei
''Trichophyton erinacei'' is a species in the fungal A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the tradit ... genus '' Trichophyton'' that is associated with hedgehogs. The fungi is normally isolated from the quills and underbelly of hedgehogs. Common symptoms of infection include crusting around the face and loss of spines. Trichophyton erinacei is also known to affect humans through hedgehog contact that transmits the fungi. Infections can also occur with indirect contact. References Arthrodermataceae Animal fungal diseases Fungus species {{Eurotiomycetes-stub ...

Microsporum Canis
''Microsporum canis'' is a pathogenic, asexual fungus in the phylum Ascomycota that infects the upper, dead layers of skin on domesticated cats, and occasionally dogs and humans. The species has a worldwide distribution. Taxonomy and evolution ''Microsporum canis'' reproduces by means of two conidial forms, large, spindle-shaped, multicelled macroconidia and small, single-celled microconidia. First records of ''M. canis'' date to 1902. Evolutionary studies have established that ''M. canis'', like the very closely related sibling species ''M. distortum'' and ''M. equinum'', is a genetic clone derived from the sexually reproducing species, ''Arthroderma otae''. Members of Ascomycota often possess conspicuous asexual and sexual forms that can coexist in time and space. ''Microsporum canis'' exemplifies a common situation in ascomycetous fungi in which, over time, one mating type strain has undergone habitat divergence from the other and established a self-sustaining reproductive ...

Trichophyton Verrucosum
''Trichophyton verrucosum'', commonly known as the cattle ringworm fungus, is a dermatophyte largely responsible for fungal skin disease in cattle, but is also a common cause of ringworm in donkeys, dogs, goat, sheep, and horses. It has a worldwide distribution, however human infection is more common in rural areas where contact with animals is more frequent, and can cause severe inflammation of the afflicted region. ''Trichophyton verrucosum'' was first described by Emile Bodin in 1902. Growth and morphology ''Trichophyton verrucosum'' is very slow-growing compared to other dermatophytes. In culture, it is characterized by being flat, white/cream colour, having an occasional dome, with a glabrous texture, known as the variant ''album'', however other variations are also found: ''T. verrucosum'' var. ''ochraceum'' has a flat, yellow, glabrous colony; ''T. verrucosum'' var. ''discoides'' has a gray-white, flat, and tomentose colony; and ''T. verrucosum'' var. ''autotrophicum'' is ...

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 ...

Antifungal Medications
An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually obtained by a doctor's prescription, but a few are available over the counter (OTC). The evolution of antifungal resistance is a growing threat to health globally. Routes of administration Ocular Indicated when the fungal infection is located in the eye. There is currently only one ocular antifungal available: natamycin. However, various other antifungal agents could be compounded in this formulation. Intrathecal Used occasionally when there's an infection of the central nervous system and other systemic options cannot reach the concentration required in that region for therapeutic benefit. Example(s): amphotericin B. Vaginal This may be used to treat some fungal infect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contact Dermatitis
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable. Contact dermatitis results from either exposure to allergens ( allergic contact dermatitis), or irritants ( irritant contact dermatitis). Allergic contact dermatitis involves a delayed type of hypersensitivity and previous exposure to an allergen to produce a reaction. Irritant contact dermatitis is the most common type and represents 80% of all cases. It is caused by prolonged exposure to irritants, leading to direct injury of the epidermal cells of the skin, which activates an immune response, resulting in an inflammatory cutaneous reaction. Phototoxic dermatitis occurs when the allergen or irritant is activated by sunlight. Diagnosis of allergic contact dermati ...

Dyshidrosis
Dyshidrosis is a type of dermatitis, characterized by itchy vesicles of in size, on the palms of the hands, sides of fingers, or bottoms of the feet. Outbreaks usually conclude within three to four weeks, but often recur. Repeated attacks may result in fissures and skin thickening. The cause of the condition is not known. Symptoms The characteristics of dyshidrosis are itchiness of the palms or soles, followed by the sudden development of intensely itchy small vesicles on the sides of the fingers, the palms or the feet, sometimes described as having a "tapioca pudding" appearance. The vesicles may develop in waves. After a few weeks, the top layer of skin may fall off and inflammation appear around the bases of the vesicles, and there may be peeling, rings of scale, or lichenification. After three to four weeks the vesicles will disappear. While they are present there is a risk of secondary bacterial infection. The locations of the eruption may be symmetrical on the body, ...
