Figure 2. MORE SECTIONS Kids site If you have signs or symptoms of a felon, cellulitis, infectious flexor tenosynovitis, or deep space infection, you should seek emergency care at once. Paronychia is one of the most common infections of the hand. Clinically, paronychia presents as an acute or a chronic condition. It is a localized, superficial infection or abscess of the paronychial tissues of the hands or, less commonly, the feet. Any disruption of the seal between the proximal nail fold and the nail plate can cause acute infections of the eponychial space by providing a portal of entry for bacteria. Treatment options for acute paronychias include warm-water soaks, oral antibiotic therapy and surgical drainage. In cases of chronic paronychia, it is important that the patient avoid possible irritants. Treatment options include the use of topical antifungal agents and steroids, and surgical intervention. Patients with chronic paronychias that are unresponsive to therapy should be checked for unusual causes, such as malignancy.

Herpetic whitlow appears as single or grouped blisters with a honeycomb appearance close to the nail.8 Diagnosis can be confirmed by Tzanck testing or viral culture. Incision and drainage is contraindicated in patients with herpetic whitlow. Suppressive therapy with a seven-to 10-day course of acyclovir 5% ointment or cream (Zovirax) or an oral antiviral agent such as acyclovir, famciclovir (Famvir), or valacyclovir (Valtrex) has been proposed, but evidence from clinical trials is lacking.15

Associated with onset of hemolytic uremic syndrome By contrast, chronic paronychia is most frequently caused by repeated exposure to water containing detergents, alkali, or other irritants. This can lead to the swelling and gradual deterioration of the epidermal layer. Unlike acute paronychia, most chronic infections are caused by the fungus Candida albicans and other fungal agents.

    Management of acute paronychia is a surprisingly evidence-light area. Firstly, for a simple acute paronychia, there is no evidence that antibiotic treatment is better than incision and drainage. If there is associated cellulitis of the affected digit (or, Heaven forbid, systemic infection) or underlying immunosuppression, then antibiotic therapy should be considered, but your first priority ought to be to get the pus out.
    The most common cause of acute paronychia is direct or indirect trauma to the cuticle or nail fold. Such trauma may be relatively minor, resulting from ordinary events, such as dishwashing, an injury from a splinter or thorn, onychophagia (nail biting), biting or picking at a hangnail, finger sucking, an ingrown nail, manicure procedures (trimming or pushing back the cuticles), artificial nail application, or other nail manipulation.3–5 Such trauma enables bacterial inoculation of the nail and subsequent infection. The most common causative pathogen is Staphylococcus aureus, although Streptococcus pyogenes, Pseudomonas pyocyanea, and Proteus vulgaris can also cause paronychia.3,6,7 In patients with exposure to oral flora, other anaerobic gram-negative bacteria may also be involved. Acute paronychia can also develop as a complication of chronic paronychia.8 Rarely, acute paronychia occurs as a manifestation of other disorders affecting the digits, such as pemphigus vulgaris.9

    In flexor tenosynovitis, the infection is within the flexor tendon sheath. This infection is particularly harmful because bacterial exotoxins can destroy the paratenon (fatty tissue within the tendon sheath) and in turn damage the gliding surface of the tendon. In addition, inflammation can lead to adhesions and scarring, and infection can lead to overt necrosis of the tendon or the sheath.

  5. Epidemiology
    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.

    Felon: Often, incision and drainage is required because the infection develops within the multiple compartments of the fingertip pad. Usually an incision will be made on one or both sides of the fingertip. The doctor will then insert an instrument into the wound and break up the compartments to aid in the drainage. Sometimes, a piece of rubber tubing or gauze will be placed into the wound to aid the initial drainage. The wound may also be flushed out with a sterile solution to remove as much debris as possible. These infections will require antibiotics. The wound will then require specific home care as prescribed by your doctor.

    Be sure to contact your doctor if:
    Diagnosis of an established joint infection is often made by clinical examination. Patients will have swelling and erythema centered on the affected joint.  Motion or axial loading of the joint will increase pain.  Assessment of joint fluid for cell count, gram stain, and crystals (acute crystalline arthropathy such as gout can mimic a joint infection) can aid in the diagnosis, but it is often quite difficult to pass a needle into the narrow joint space and obtain an adequate sample.  Serum markers of inflammation (such as white blood cell count, erythrocyte sedimentation rate, and C – reactive protein) are not typically elevated with an infection of a small joint of the hand.  Xrays should be obtained to ensure that there is no fracture or retained tooth fragment.

  7. Chronic paronychia can occur on your fingers or toes, and it comes on slowly. It lasts for several weeks and often comes back. It’s typically caused by more than one infecting agent, often Candida yeast and bacteria. It’s more common in people who’re constantly working in water. Chronically wet skin and excessive soaking disrupts the natural barrier of the cuticle. This allows yeast and bacteria to grow and get underneath the skin to create an infection.

    Some practitioners use topical antibiotics for these patients and there is some evidence that if you are going to give topical antibiotics, there is some (weak) evidence that adding a topical steroid (betamethasone) to your fusidic acid might speed up resolution of pain. I do tend to send a pus swab off if I get some good stuff out – particularly for those immunocompromised patients I’m going to treat with antibiotics from the outset.
