MPR Felon: This bacterial infection of the finger pad, caused by the same organisms that cause paronychia, is usually the result of a puncture wound. The wound allows the introduction of bacteria deep into the fingertip pad. Because the fingertip has multiple compartments, the infection is contained in this area. frequent sucking on a finger Deep space infections: Much like flexor infectious tenosynovitis, this can require emergency care. If the infection is mild, then only oral antibiotics may be needed. If more severe, a hand surgeon should evaluate the wound and IV antibiotics begun. Often these wounds will require incision and drainage followed by a course of antibiotics. Scott D.

SMACC Creep Diagnosis Prevention & Treatment Components of the nail complex include the nail bed (matrix), the nail plate and the perionychium. The nail bed lies beneath the nail plate and contains the blood vessels and nerves. Within the nail bed is the germinal matrix, which is responsible for the production of most of the nail volume, and the sterile matrix. This matrix is the “root” of the nail, and its distal portion is visible on some nails as the half-moon–shaped structure called the lunula.1 The nail plate is hard and translucent, and is composed of dead keratin.2 The plate is surrounded by the perionychium, which consists of proximal and lateral nail folds, and the hyponychium, the area beneath the free edge of the nail1 (Figure 1). There is some disagreement about the importance and role of Candida in chronic paronychia.10,21 Although Candida is often isolated in patients with chronic paronychia, this condition is not a type of onychomycosis, but rather a variety of hand dermatitis21 caused by environmental exposure (Figure 3). In many cases, Candida disappears when the physiologic barrier is restored.12 Chronic paronychia in a patient with hand dermatitis. My Tools Virchester Journal Club 2014. St.Emlyn’s More Topics Types Bacteria cause most of these finger infections. The exception to this is the herpetic whitlow, which is caused by a virus. How the infection starts and is found in a particular location is what makes each specific type of infection unique. Usually some form of trauma is the initial event. This may be a cut, animal bite, or puncture wound. Ensure that your manicurist always uses sterile instruments.

This chapter (similar to the one on nail disorders) does not, by design and of necessity, follow the the outline globally. rather, there are mini-sections on each infection. Your doctor may prescribe an antibiotic if the infection is more severe or if it isn’t responding to home treatments. Ignoring an infected hangnail can make your condition worse. In rare situations, the infection may spread to other parts of your body if left untreated. Contact your doctor if you have pus around or under the nail or if the infection doesn’t get better within a week.
