Dermatology
Dermatology is the branch of medicine dealing with the 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, hair, nails, and some cosmetic problems. 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 ar ...

Hair Disease
Hair diseases are disorders primarily associated with the follicles of the hair. A few examples are: * Bubble hair deformity * Hair casts (shedding of remnants of the inner root sheath) * Hair loss Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body. Typically at least the head is involved. The severity of hair loss can vary from a small area to the entire body. Inflammation or scarr ... (alopecia) * Hirsutism (excessive hair on body parts with usually minimal hair) * Hypertrichosis (excessive hair growth) * Ingrown hair * Monilethrix (beaded hair) * Premature greying of hair * Pattern hair loss * Trichorrhexis invaginata (hair shaft abnormality) * Trichotillomania (hair-pulling disorder) Many hair diseases can be associated with distinct underlying disorders. Piedra are fungal diseases. Hair disease may refer to excessive shedding or baldness (or both). Balding can be localised or diffuse, scarring or non-scarring. Incr ...

Fungus
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Piedra
White piedra (or tinea blanca) is a mycosis of the hair caused by several species of fungi in the genus '' Trichosporon''. It is characterized by soft nodules composed of yeast cells and arthroconidia that encompass hair shafts. Diagnosis White piedra can occur on the hair of the scalp; ''Trichosporon ovoides'' is likely the cause in this case. White piedra on scalp hair is rarely caused by ''Trichosporon inkin''; pubic hair with white piedra is what ''T. inkin'' is mainly associated with. White piedra can occur on pubic hair; ''T. inkin'' likely causes this. ''Trichosporon beigelii'' Treatment There are several approaches to treat this infectious disease. One approach involves shaving the affected areas. Another approach involves the use of antifungal medication 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 ...

Black Piedra
''Piedraia hortae'' is a superficial fungus that exists in the soils of tropical and subtropical environments and affects both sexes of all ages. The fungus grows very slowly, forming dark hyphae, which contain chlamydoconidia cells and black colonies when grown on agar. ''Piedraia hortae'' is a dermatophyte and causes a superficial fungal infection known as black piedra, which causes the formation of black nodules on the hair shaft and leads to progressive weakening of the hair. The infection usually infects hairs on the scalp and beard, but other varieties tend to grow on pubic hairs. The infection is usually treated with cutting or shaving of the hair and followed by the application of anti-fungal and topical agents. The fungus is used for cosmetic purposes to darken hair in some societies as a symbol of attractiveness. Morphology When grown on agar at ''Piedraia hortae'' grows very slowly to form black-greenish, limited and pointed colonies. ''Piedraia hortae'' taken from in ...

Animal Fungal Diseases
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...
