Trichoscopy
Trichoscopy is a method of hair and scalp evaluation and is used for diagnosing hair and scalp diseases. The method is based on dermoscopy. In trichoscopy hair and scalp structures may be visualized at many-fold magnification. Currently magnifications ranging from 10-fold to 70-fold are most popular in research and clinical practice. The method was developed by groups of dermatologists directed by: Lidia Rudnicka in Poland, Antonella Tosti and Giuseppe Micali in Italy and Shigeki Inui in Japan. In 2004 Francesco Lacarrubba and coworkers first described videodermoscopic features of alopecia areata (micro-exclamation hairs, yellow hyperkeratotic hair follicle openings, and black cadaverized hairs. In 2005 Malgorzata Olszewska and Lidia Rudnicka first used videodermoscopy for evaluation of disease severity in androgenic alopecia and for monitoring treatment efficacy. Characteristic images of female androgenic alopecia included hair shaft heterogeneity and increased percentage of thin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dermoscopy
Dermatoscopy also known as dermoscopy or epiluminescence microscopy, is the examination of skin lesions with a dermatoscope. It is a tool similar to a camera to allow for inspection of skin lesions unobstructed by skin surface reflections. The dermatoscope consists of a magnifier, a light source (polarized or non-polarised), a transparent plate and sometimes a liquid medium between the instrument and the skin. Dermatoscope is often handheld, although there are stationary cameras allowing the capture of whole body images in a single shot. When the images or video clips are digitally captured or processed, the instrument can be referred to as a digital epiluminescence dermatoscope. The image is then analyzed automatically and given a score indicating how dangerous it is. This technique is useful to dermatologists and skin cancer practitioners in distinguishing benign from malignant (cancerous) lesions, especially in the diagnosis of melanoma. Types of dermatoscopy There are two ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alopecia Areata
Alopecia areata, also known as spot baldness, is a condition in which hair is lost from some or all areas of the body. Often, it results in a few bald spots on the scalp, each about the size of a coin. Psychological stress and illness are possible factors in bringing on alopecia areata in individuals at risk, but in most cases there is no obvious trigger. People are generally otherwise healthy. In a few cases, all the hair on the scalp is lost (''alopecia totalis''), or all body hair is lost ('' alopecia universalis''). Hair loss can be permanent, or temporary. It is distinct from pattern hair loss, which is common among males. Alopecia areata is believed to be an autoimmune disease resulting from a breach in the immune privilege of the hair follicles. Risk factors include a family history of the condition. Among identical twins, if one is affected, the other has about a 50% chance of also being affected. The underlying mechanism involves failure by the body to recognize it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Androgenic Alopecia
Pattern hair loss (also known as androgenetic alopecia (AGA)) is a hair loss condition that primarily affects the top and front of the scalp. In male-pattern hair loss (MPHL), the hair loss typically presents itself as either a receding front hairline, loss of hair on the crown (vertex) of the scalp, or a combination of both. Female-pattern hair loss (FPHL) typically presents as a diffuse thinning of the hair across the entire scalp. Male pattern hair loss seems to be due to a combination of oxidative stress, the microbiome of the scalp, genetics, and circulating androgens; particularly dihydrotestosterone (DHT). Men with early onset androgenic alopecia (before the age of 35) have been deemed as the male phenotypic equivalent for polycystic ovary syndrome (PCOS). As an early clinical expression of insulin resistance and metabolic syndrome, AGA is related to being an increased risk factor for cardiovascular diseases, glucose metabolism disorders, type 2 diabetes, and enlargement ...

Monilethrix
Monilethrix (also referred to as beaded hair) is a rare autosomal dominant hair disease that results in short, fragile, broken hair that appears beaded. It comes from the Latin word for necklace (''monile'') and the Greek word for hair (''thrix''). Hair becomes brittle, and breaks off at the thinner parts between the beads. It appears as a thinning or baldness of hair and was first described in 1897 by Walter Smith Signs and symptoms Some indicators of monilethrix are small bumps on the skin, mainly on the scalp, neck and arms. In most cases, firm, dark papules, covered with dark scales and crusts appears on the skin, especially the scalp. The affected individual would have beaded hair strands. The possible areas for the hair loss are the eyebrows, eyelashes, limbs, and pubic region. Hair strands are usually dull, dry, and brittle. The strands are prone to mild to severe breakage, causing onset alopecia, especially during pregnancy. Fingernail and toenails tend to appear abnorma ...

Telogen Effluvium
Telogen effluvium is a scalp disorder characterized by the thinning or shedding of hair resulting from the early entry of hair in the telogen phase (the resting phase of the hair follicle).Marks, James G; Miller, Jeffery (2006). ''Lookingbill and Marks' Principles of Dermatology'' (4th ed.). Elsevier Inc. Page 263. .James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. . It is in this phase that telogen hairs begin to shed at an increased rate, where normally the approximate rate of hair loss (having no effect on one's appearance) is 125 hairs per day. There are 5 potential alterations in the hair cycle that could lead to this shedding: immediate anagen release, delayed anagen release, short anagen syndrome, immediate telogen release, and delayed telogen release. * Immediate anagen release occurs when follicles leave anagen and are stimulated to enter telogen prematurely. The effects become visible 2– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Netherton Syndrome
Netherton syndrome is a severe, autosomal recessive form of ichthyosis associated with mutations in the ''SPINK5'' gene. It is named after Earl W. Netherton (1910–1985), an American dermatologist who discovered it in 1958.Netherton, E. W. A unique case of trichorrhexis nodosa: 'bamboo hairs.'. Arch. Derm. 78: 483-487, 1958. Signs and symptoms Netherton syndrome is characterized by chronic skin inflammation, universal pruritus (itch), severe dehydration, and stunted growth. Patients with this disorder tend to have a hair shaft defect ( trichorrhexis invaginata), also known as "bamboo hair". The disrupted skin barrier function in affected individuals also presents a high susceptibility to infection and allergy, leading to the development of scaly, reddish skin similar to atopic dermatitis. In severe cases, these atopic manifestations persist throughout the individual's life, and consequently post-natal mortality rates are high. In less severe cases, this develops into the milde ...

Cicatricial Alopecia
Scarring hair loss, also known as cicatricial alopecia, is the loss of hair which is accompanied with scarring. This is in contrast to non scarring hair loss. It can be caused by a diverse group of rare disorders that destroy the hair follicle, replace it with scar tissue, and cause permanent hair loss. A variety of distributions are possible.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). Page 647. McGraw-Hill. . In some cases, hair loss is gradual, without symptoms, and is unnoticed for long periods. In other cases, hair loss is associated with severe itching, burning and pain and is rapidly progressive. The inflammation that destroys the follicle is below the skin surface and there is usually no "scar" seen on the scalp. Affected areas of the scalp may show little signs of inflammation, or have redness, scaling, increased or decreased pigmentation, pustules, or draining sinuses. Scarring hair loss occurs in otherwise healthy people of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
