Chronic paronychia is an infection of the folds of tissue surrounding the nail of a finger or, less commonly, a toe, lasting more than six weeks. [4] It is a nail disease prevalent in individuals whose hands or feet are subject to moist local environments, and is often due to contact dermatitis .
A simple wound, if not treated properly, can quickly turn serious. Here’s how to ID signs of a developing infection so you can treat it before it causes real trouble.
Kanavel's sign is a clinical sign found in patients with infection of a flexor tendon sheath in the hand (pyogenic flexor tenosynovitis), a serious condition which can cause rapid loss of function of the affected finger. [1] The sign consists of four components: [2] the affected finger is held in slight flexion.
The relative rarity of this condition in the fingers suggests that pressure from the ground or shoe against the toe is a prime factor. The movements involved in walking or other physical disturbances can contribute to the problem. Mild onychocryptosis, particularly in the absence of infection, can be treated by trimming and rounding the nail.
The onset of symptoms is typically 3 to 21 days following infection. Recovery may take months; about 10% of cases prove to be fatal. [1] C. tetani is commonly found in soil, saliva, dust, and manure. The bacteria generally enter through a break in the skin, such as a cut or puncture wound caused by a contaminated object.
It enters through small cuts in the skin to cause a fungal infection. [1] In cases of sporotrichosis affecting the lungs, the fungal spores enter by inhalation. [1] Sporotrichosis can be acquired by handling cats with the disease; it is an occupational hazard for veterinarians. [1] Treatment depends on the site and extent of infection. [1]
Often, gangrene is associated with underlying infection, thus the gangrenous tissue must be debrided to hinder the spread of the associated infection. The extent of surgical debridement needed depends on the extent of the gangrene and may be limited to the removal of a finger, toe, or ear, but in severe cases may involve a limb amputation. [13]
His mother Trina White, an infectious disease nurse, examined the cut and thought it looked fine. There was no infection. But nearly two weeks later, Riley woke up feeling like he had the flu.
