Corpuscule de Meissner. Les corpuscules de Meissner, découverts par l'anatomiste Georg Meissner (1829 - 1905), sont des récepteurs sensoriels formés de terminaisons encapsulées, situés dans le derme papillaire (partie supérieure du derme ), particulièrement sensibles au toucher léger. Localisés dans les régions à haute sensibilité ...
Anatomist, physiologist. George Meissner (19 November 1829 – 30 March 1905) [1] was a German anatomist and physiologist born in Hanover . He studied medicine at the University of Göttingen, where he worked closely with Rudolf Wagner (1806–1864). In 1851 he accompanied Wagner and Theodor Billroth (1829–1894) on an expedition to Trieste ...

The most common symptom of a fungal nail infection is the nail becoming thickened and discoloured: white, black, yellow or green. As the infection progresses the nail can become brittle, with pieces breaking off or coming away from the toe or finger completely. If left untreated, the skin underneath and around the nail can become inflamed and painf...
The causative pathogens of onychomycosis are all in the fungus kingdom and include dermatophytes, Candida (yeasts), and nondermatophytic molds. Dermatophytes are the fungi most commonly responsible for onychomycosis in the temperate western countries; while Candidaand nondermatophytic molds are more frequently involved in the tropics and subtropics...
The diagnosis is generally suspected based on the appearance and confirmed by laboratory testing. The four main tests are a potassium hydroxide smear, culture, histology examination, and polymerase chain reaction. The sample examined is generally nail scrapings or clippings.These being from as far up the nail as possible. Nail plate biopsy with per...
Medications
Most treatments are with antifungal medications, either topically or by mouth. Avoiding use of antifungal therapy by mouth (e.g., terbinafine) in persons without a confirmed infection is recommended, because of the possible side effects of that treatment. Medications that may be taken by mouth include terbinafine (76% effective), itraconazole (60% effective), and fluconazole (48% effective). They share characteristics that enhance their effectiveness: prompt penetration of the nail and nail b...

Chemical (keratolytic) or surgical debridementof the affected nail appears to improve outcomes. As of 2014 evidence for laser treatment is unclear as the evidence is of low qualityand varies by type of laser. Tea tree oilis not recommended as a treatment on present data. It was found to irritate the surrounding skin in some trial participants.
Recurrence may occur following treatment, with a 20-25% relapse rate within 2 years of successful treatment. Nail fungus can be painful and cause permanent damage to nails. It may lead to other serious infections if the immune system is suppressed due to medication, diabetes or other conditions. The risk is most serious for people with diabetes and...
A 2003 survey of diseases of the foot in 16 European countries found onychomycosis to be the most frequent fungal foot infection and estimated its prevalence at 27%. Prevalence was observed to increase with age. In Canada, the prevalence was estimated to be 6.48%. Onychomycosis affects approximately one-third of diabetics and is 56% more frequent i...
The term is from Ancient Greek ὄνυξ onyx "nail", μύκης mykēs "fungus", and the suffix -ωσις ōsis"functional disease".
Research suggests that fungi are sensitive to heat, typically 40–60 °C (104–140 °F). The basis of laser treatment is to try to heat the nail bed to these temperatures in order to disrupt fungal growth. As of 2013 research into laser treatment seemed promising. There is also ongoing development in photodynamic therapy, which uses laser or LED light ...

Clear interior substance. Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. [1] [2] This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to pressure. In particular, they have their highest sensitivity (lowest ...

Oct 10, 2022 · Here, an annotated translation of Meissner's first description of the submucosal plexus is provided along with a short biography of Georg Meissner and a review of the scientific literature and controversy surrounding his discovery.
In 1851, Meissner (and Billroth, who had to return halfway in Vienna after he was informed of his mother's death) joined Wagner on a zoological research trip to Trieste studying the nerves of electric rays. 4 Continuing this work under Wagner's supervision in Göttingen, Meissner made one of his major discoveries, tactile receptors of the skin ...
