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.

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] |
Malignant Melanoma
Melanoma, also redundantly known as malignant melanoma, is a type of skin cancer that develops from the Biological pigment, pigment-producing cells known as melanocytes. Melanomas typically occur in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma). In women, they most commonly occur on the legs, while in men, they most commonly occur on the back. About 25% of melanomas develop from nevus, moles. Changes in a mole that can indicate melanoma include an increase in size, irregular edges, change in color, itchiness, or ulcer (dermatology), skin breakdown. The primary cause of melanoma is ultraviolet light (UV) exposure in those with low levels of the human skin color, skin pigment melanin. The UV light may be from the sun or other sources, such as tanning lamp, tanning devices. Those with many moles, a history of affected family members, and immunosuppression, poor immune function are at greater risk. A number of rare genetic conditions, such as xerod ...

Molemax
MoleMax was the first digital epiluminescence microscopy (dermatoscopy) system developed in cooperation with medical faculty Department of Dermatology of the Medical University of Vienna. It is currently owned and distributed by DermaMedicalSystems. History In 1997, MoleMax was presented to international experts at the Melanoma World Congress and the following Dermatology World Congress in Sydney and generated great public interest. Since then, over 2000 MoleMax systems are in use in over 50 countries. Today, MoleMax is worldwide accepted clinical standard in digital epiluminescence microscopy. Methodology Thanks to the worldwide patented light polarisation technique for cameras with skin contact, these camera systems do not require any immersion fluid for the epiluminescence microscopic analysis. Scientific use The MoleMax system was part of multiple scientific works such as measurements of the growth rate of pigmented skin lesion A skin condition, also known as c ...

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 ...

Ernst Abbe
Ernst Karl Abbe HonFRMS (23 January 1840 – 14 January 1905) was a German physicist, optical scientist, entrepreneur, and social reformer. Together with Otto Schott and Carl Zeiss, he developed numerous optical instruments. He was also a co-owner of Carl Zeiss AG, a German manufacturer of scientific microscopes, astronomical telescopes, planetariums, and other advanced optical systems. Personal life Abbe was born 23 January 1840 in Eisenach, Saxe-Weimar-Eisenach, to Georg Adam Abbe and Elisabeth Christina Barchfeldt. He came from a humble home – his father was a foreman in a spinnery. Supported by his father's employer, Abbe was able to attend secondary school and to obtain the general qualification for university entrance with fairly good grades, at the Eisenach Gymnasium, which he graduated from in 1857. By the time he left school, his scientific talent and his strong will had already become obvious. Thus, in spite of the family's strained financial situation, his father ...
