Patients with acute paronychia may report localized pain and tenderness of the perionychium. Symptoms may arise spontaneously, or following trauma or manipulation of the nail bed. The perionychial area usually appears erythematous and inflamed, and the nail may appear discolored and even distorted. If left untreated, a collection of pus may develop as an abscess around the perionychium. Fluctuance and local purulence at the nail margin may occur, and infection may extend beneath the nail margin to involve the nail bed. Such an accumulation of pus can produce elevation of the nail plate (Table 1).6 5 References Shaimaa Nassar, MBBCH, Dip(RCPSG) Don’t bite or pick your nails. Keep nails short ONGOING Paronychia is an inflammation of the folds of tissue surrounding the nail of a toe or finger. Paronychia may be classified as either acute or chronic. The main factor associated with the development of acute paronychia is direct or indirect trauma to the cuticle or nail fold. This enables pathogens to inoculate the nail, resulting in infection. Treatment options for acute paronychia include warm compresses; topical antibiotics, with or without corticosteroids; oral antibiotics; or surgical incision and drainage for more severe cases. Chronic paronychia is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. The patient should avoid exposure to contact irritants; treatment of underlying inflammation and infection is recommended, using a combination of a broad-spectrum topical antifungal agent and a corticosteroid. Application of emollient lotions may be beneficial. Topical steroid creams are more effective than systemic antifungals in the treatment of chronic paronychia. In recalcitrant chronic paronychia, en bloc excision of the proximal nail fold is an option. Alternatively, an eponychial marsupialization, with or without nail removal, may be performed. psychiatry Rick Body.

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. twitter WebMD Mobile Female Incontinence Page information swelling Supplements Allergic contact dermatitis or primary irritation due to certain nail polish or latex or excessive repeated habitual wet products Help Peer Review this article.

Expert Blogs and Interviews For persistent lesions, oral antistaphylococcal antibiotic therapy should be used in conjunction with warm soaks.11,16,17 Patients with exposure to oral flora via finger sucking or hangnail biting should be treated against anaerobes with a broad-spectrum oral antibiotic (e.g., amoxicillin/clavulanate [Augmentin], clindamycin [Cleocin]) because of possible S. aureus and Bacteroides resistance to penicillin and ampicillin.3,11,17,18  Medications commonly used in the treatment of acute paronychia are listed in Table 1.3,10–13,17–22 More in Pubmed Chronic paronychia. The underlying agent of infection in chronic paronychia is most commonly Candida yeast, but it can also be bacteria. Because yeasts grow well in moist environments, this infection is often caused by having your feet or hands in water too much of the time. Chronic inflammation also plays a role.

Trimethoprim/sulfamethoxazole (TMP/SMX; Bactrim, Septra)* (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.) Multiple Myeloma TOPICS See additional information.

People who have jobs that frequently expose their hands to water or irritants such as chemicals used in washing dishes are at an increased risk of chronic paronychia.

University of Maryland Cardiology Symposium When to see your doctor Fungal Nail Infection 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 of the infections can be treated in a doctor's office or clinic, but several will require inpatient treatment and IV antibiotics. Because the organisms that cause these infections are similar, many of the same types of antibiotics may be used. In chronic paronychia, the cuticle separates from the nail plate, leaving the region between the proximal nail fold and the nail plate vulnerable to infection by bacterial and fungal pathogens.12,21 Chronic paronychia has been reported in laundry workers, house and office cleaners, food handlers, cooks, dishwashers, bartenders, chefs, fishmongers, confectioners, nurses, and swimmers. In such cases, colonization with Candida albicans or bacteria may occur in the lesion.19,21 Acute paronychia is typically diagnosed based on a review of the clinical symptoms. If there is a pus discharge, your doctor may perform a bacterial culture for a definitive diagnosis. (In all but the most severe cases, this may not be considered necessary since the bacteria will usually be either a Staphylococcus or Streptococcus type, both of which are treated similarly.)

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. 25. Garcia-Silva J, Almagro M, Peña-Penabad C, Fonseca E.

Pus formation is uncommon. Common finger infections include paronychia, felon, and herpetic whitlow. A paronychia is an acute or chronic soft tissue infection around the nail body. Acute infections are typically bacterial in origin and usually occur after minor trauma. Chronic paronychia infections have a multifactorial etiology, often related to repeated exposure to moist environments and/or skin irritants, and may be accompanied by secondary fungal infection. The diagnosis of paronychia is based on clinical signs of inflammation. A bacterial culture or fungal stain can confirm the causative pathogen. Treatment of acute paronychia usually involves antibiotics, while chronic paronychia is treated with topical steroids and antifungal therapy. Complications include nail dystrophy or felon. you have diabetes and you suspect your hangnail is infected Collagen Supplements Patient leaflets 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.
