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 ...

Hair Disease
Hair diseases are illnesses that impact the persistence and regular growth of hair. Types of hair diseases include folliculitis, hirsutism, hypertrichosis, hypotrichosis (alopecia), Menkes kinky hair syndrome, monilethrix, and piedra. Folliculitis Folliculitis is an inflammatory response that occurs in the hair follicle's superficial part and may affect either the perifollicular or follicular opening. Hirsutism Hirsutism is characterized as the overgrowth of terminal hair in a typical male pattern distribution on a female's face and body. Hypertrichosis Hypertrichosis is any place of the body where there is more hair growth than is typically seen in people of the same age, race, and sex, excluding androgen-induced hair growth. Hypotrichosis Hypotrichosis is an uncommon condition where there is little to no hair development on the head, in the places of the body where hair normally grows, such as the brows above the eyes and the edges of the eyelids.

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] |
White Piedra
White piedra (or tinea blanca) is a mycosis of the hair caused by several species of fungi in the genus Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In bino ... '' Trichosporon''. It is characterized by soft nodules composed of yeast cells and arthroconidia that encompass hair shafts. Signs and symptoms White piedra is asymptomatic. Diagnosis White piedra is caused by ''Trichosporon beigelii.'' 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 mucoides'' can also cause white piedra. In such cases, ...

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 i ...

Animal Fungal Diseases
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
