Callushttps://en.wikipedia.org/wiki/Callus
Callus ass e Gebitt vun der verdickter Haut déi sech als Äntwert op widderholl Reibung, Drock oder aner Reizung formt. Calluses sinn allgemeng net schiedlech an hëllefen Bléiser ze vermeiden, souwéi Schutz ze bidden. Wéi och ëmmer, exzessiv Bildung kann heiansdo zu anere Probleemer féieren, wéi zum Beispill Hautulceratioun oder Infektioun.

  • Calluses sinn um lénke Fouss (plantar) a rietse Fouss (lateral).
  • Corns (calluses) geschitt symmetresch op béide Féiss, wou Drock ugewannt gëtt oder wou de Schong géint de Fouss dréckt. Wann eng ähnlech Läsioun an engem Gebitt ouni Drock geschitt ass, sollt e Warzen verdächtegt ginn.

Corns entwéckelen sech aus widderholl reiwen oder Drock. Corn ass e spezifescht Gebitt vun der verdickter Haut, wärend callus méi verbreet ass. Corns geschitt dacks bei Athleten oder Leit mat Foussproblemer wéi ongläich Reibung vu Schong. Si sinn och heefeg bei eeler Leit, Diabetiker, an Amputéierten. Corns soll als Symptom gesi ginn anstatt e Standalone Zoustand.
A corn, also known as a calvus, heloma, or focal intractable plantar hyperkeratosis, is a type of callosity. Corns are uncomfortable, thickened skin lesions that result from repeated mechanical trauma due to friction or pressure forces. In the literature, confusing terminology is often used to call different types of hyperkeratotic skin lesions. Nevertheless, a corn should be distinguished from a callus, which is a more diffuse type of callosity. Thus, a corn is a well-delimited focal area of hyperkeratosis. This condition is often seen in athletes and patients exposed to unequal friction force from footwear or gait problems, including the elderly, patients with diabetes, and amputees. It should be regarded as a symptom rather than an effective disease.

Corn , och bekannt als Clavus, ass e gemeinsame Foussbedingung, deen an de Kliniken gesi gëtt. Et ass e verdickte Gebitt vun der Haut verursaacht duerch Reibung oder Drock, dacks schmerzhaf. Et ass wichteg et ze ënnerscheeden vu Calluses oder Warzen. Calluses sinn ähnlech awer feelen den zentrale Kär a si manner schmerzhaf. D'Behandlung zielt fir d'Symptomer ze entlaaschten an zukünfteg Mais ze vermeiden. D'Behandlung vun dësem schmerzhafte Zoustand kann d'Liewe vun de Patienten immens verbesseren, besonnesch fir eeler oder aktiv Persounen.
A clavus or clavi (plural) is a frequently encountered condition in the out-patient clinic, known colloquially as a corn. It is one of the many hyperkeratotic lesions of the foot and therefore requires differentiation from other etiologies such as calluses or plantar warts. A clavus is a well-demarcated thickened area of the epidermis that has a central core. This skin lesion is most commonly found on the foot and is often painful. A clavus results from repeated friction, pressure, or trauma to a specific area of the foot. A callus is another hyperkeratotic skin lesion that is similar to a clavus. It is an area of thickened epidermis with less defined borders and is also the result of repeated mechanical stress. Additionally, calluses lack the painful central core seen with clavi. Calluses most commonly present on the hands and feet. The older and the physically active are most commonly affected by clavi. Treatment focuses on symptomatic relief and lifestyle modification to prevent future clavus formation. By treating this painful and sometimes life-altering skin lesion, physicians can have a profound impact on their patients’ lives.
