Émile Vidal
Jean Baptiste Émile Vidal (18 June 1825 – 16 June 1893) was a French dermatologist who was a native of Paris. He studied medicine in Tours and Paris, becoming ''médecin des hôpitaux'' in 1862. For much of his career he was associated with the Hôpital Saint-Louis (1867–1890) in Paris. In 1883 he became a member of the ''Académie de Médecine''. In 1893, Vidal was the first to recognize and define the transmission of herpes simplex virus from one person to another. He is remembered for his investigations of lupus erythematosus, lupus and skin lichenification. His name is associated with "pityriasis circinata et marginata of Vidal", a disorder that is synonymous to pityriasis rosea, and "Vidal's disease", an historical name for lichen simplex chronicus.

Louis-Anne-Jean Brocq
Louis-Anne-Jean Brocq (1 February 1856 – 18 December 1928) was a French dermatologist born in Laroque-Timbaut, a village in the department of Lot-et-Garonne. He practiced medicine in Paris at the Hospice la Rochefoucauld, the Hôpital Broca, and from 1906 to 1921, the Hôpital Saint-Louis. As a young physician he studied and worked with Jean Alfred Fournier (1832–1915), Jean Baptiste Emile Vidal (1825–1893) and Ernest Henri Besnier (1831–1909). Brocq provided early, comprehensive descriptions of numerous skin disorders, including keratosis pilaris, parapsoriasis and a form of dermatitis called "Duhring-Brocq disease" (named with Louis Adolphus Duhring and sometimes referred to as dermatitis herpetiformis). Other eponymous skin diseases named after him are " Brocq's pseudopelade", a condition involving progressive scarring of the scalp, and "Brocq-Pautrier angiolupoid", a specific type of sarcoidosis of the skin named in conjunction with Dr. Lucien-Marie Pautrier (18 ...

Lichen Simplex Chronicus
Lichen simplex chronicus (LSC) is thick leathery skin with exaggerated skin markings caused by sudden itching and excessive rubbing and scratching. It generally results in small bumps, patches, scratch marks and scale. It typically affects the neck, scalp, upper eyelids, ears, palms, soles, ankles, wrists, genital areas and bottom. It often develops gradually and the scratching becomes a habit. Signs and symptoms People burdened with LSC report pruritus, followed by uncontrollable scratching of the same body region, excessively. Most common sites of LSC are the sides of the neck, the scalp, ankles, vulva, pubis, scrotum, and extensor sides of the forearms. However, due to the stigma associated with chronic scratching, some patients will not admit to chronic rubbing or abrasion. The skin may become thickened and hyperpigmented (lichenified) as a direct result of chronic excoriation. Typically this period of increased scratching is associated with stressors.

Pityriasis Rosea
Pityriasis rosea is a type of skin rash. Classically, it begins with a single red and slightly scaly area known as a "herald patch". This is then followed, days to weeks later, by an eruption of many smaller scaly spots; pinkish with a red edge in people with light skin and greyish in darker skin. About 20% of cases show atypical deviations from this pattern. It usually lasts less than three months and goes away without treatment. Sometimes malaise or a fever may occur before the start of the rash or itchiness, but often there are few other symptoms. While the cause is not entirely clear, it is believed to be related to human herpesvirus 6 (HHV6) or human herpesvirus 7 (HHV7). It does not appear to be contagious. Certain medications may result in a similar rash. Diagnosis is based on the symptoms. Evidence for specific treatment is limited. About 1.3% of people are affected at some point in time. It most often occurs in those between the ages of 10 and 35. The condition was des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichenification
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions result ...

Dermatologist
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 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 Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία '' -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 ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al.

Lupus Erythematosus
Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues. Symptoms of these diseases can affect many different body systems, including joints, skin, kidneys, blood cells, heart, and lungs. The most common and most severe form is systemic lupus erythematosus. Signs and symptoms Symptoms vary from person to person, and may come and go. Almost everyone with lupus has joint pain and swelling. Some develop arthritis. Frequently affected joints are the fingers, hands, wrists, and knees. Other common symptoms include: * chest pain during respiration * joint pain (stiffness and swelling) * painless oral ulcer * fatigue * weight loss * headaches * fever with no other cause * Skin lesions that appear worse after sun exposure * general discomfort, uneasiness, or ill feeling ( malaise) * hair loss * sensitivity to sunlight * a "butterfly" facial rash, seen in about half of people with SLE * swollen lymp ...

Herpes Simplex Virus
Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known by their taxonomical names ''Human alphaherpesvirus 1'' and '' Human alphaherpesvirus 2'', are two members of the human ''Herpesviridae'' family, a set of viruses that produce viral infections in the majority of humans. Both HSV-1 and HSV-2 are very common and contagious. They can be spread when an infected person begins shedding the virus. As of 2016, about 67% of the world population under the age of 50 had HSV-1. In the United States, about 47.8% and 11.9% are estimated to have HSV-1 and HSV-2, respectively, though actual prevalence may be much higher. Because it can be transmitted through any intimate contact, it is one of the most common sexually transmitted infections. Symptoms Many of those who are infected ''never'' develop symptoms. Symptoms, when they occur, may include watery blisters in the skin or mucous membranes of the mouth, lips, nose, genitals, or eyes (herpes simplex keratitis). Lesions heal with a ...
