Shafritz, A. and Coppage, J. "Acute and Chronic Paronychia of the Hand." Journal of the American Academy of Orthopaedic Surgeons. March 2014;22(3):165-178. 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. SKIN CANCER Cracked heels and dry skin on your feet are common. Learn about home remedies and traditional treatments to get rid of the dry skin on your feet. Once treated by stronger medications, the hangnail should clear up within 5 to 7 days. #FOAMed, Emergency Medicine, Featured, Minor Injuries, musculoskeletal Medscape Reference Vaccines Infected hangnails need appropriate treatment, many of which can be done at home. You should see a doctor if the infected hangnail doesn’t heal after about a week of home treatment. If you require medical treatment for the infected hangnail, your symptoms should go away after a few days. If you have a chronic condition, it may take several weeks to completely heal. Ambulatory Care Chronic paronychia tends to be more difficult to diagnose. A potassium hydroxide (KOH) test, in which a smear is extracted from the nail fold, can sometimes confirm a fungal infection. If pus is involved, a culture is usually the best way to confirm the presence of fungus or other, less common infective agents.

Pus is usually present, along with gradual thickening and browning discoloration of the nail plate. Cellulitis: The area will be red and warm to the touch. The area may be slightly swollen and tender. This is usually a superficial infection, so the deep structures should not be involved. The motion of the fingers and hand should not be difficult or painful. If painful or difficult, this may indicate a deep space infection of some type.  ·  Printed by Atlassian Confluence , the Enterprise Wiki. The outlook is good if you have a mild case of acute paronychia. You can treat it successfully, and it’s unlikely to return. If you let it go untreated for too long, the outlook is still good if you get medical treatment.

Resus & Crit Care First Aid and Injury Prevention Acute paronychia: The major causative organism is Staphylococcus aureus. Less common organisms are Streptococcus species, Pseudomonas or Proteus spp. Immediate Pain Relief Slideshow Tips to Help You Stop Wasting Time  ·  Report a bug All About Pregnancy Neurology Advisor WebMD Network Usually, depending on the severity and the pathogenic cause(s) of the acute paronychia, a systemic antibiotic should be given to the patient against S.aureus (sometimes Streptococcus pyogenes or Pseudomonas aeruginosa causing the greenish-black in color beneath the nail plate, is the cause of the acute paronychia). Among the different systemic antibiotics that could be used are Flucloxacillin, 250mg 4 times daily for up to 10 days or Clindamycin, 300mg twice daily for 7-10 days. In addition, immunosuppressed patients are more likely to have chronic paronychia, particularly diabetics and those on steroids. It is worth noting that indinavir (an antiretroviral drug) is associated with chronic paronychia, particularly of the big toe, which resolves when the drug is ceased. Psoriasis might also predispose to chronic paronychia as well as being a differential diagnosis in these patients. Find a Doctor Chronic paronychia is a little different. It is a kind of dermatitis-type reaction, usually representing damage to the protective barrier of the nail or its tissues, often due to frequent hand washing and/or exposure to harsh chemicals or cold and wet (for this reason, chronic paronychia are more often seen in people who handwash a lot – such as healthcare workers, bar tenders and food processors – and in swimmers, fishermen etc.). Often more than one finger is affected; nail changes such as pitting may be seen too. Paronychia means inflammation of the nail apparatus. Acute paronychias are infections of the periungual tissues, usually presenting with an acutely painful, purulent infection. [Figure caption and citation for the preceding image starts]: Acute paronychia From the collection of Dr N.J. Jellinek and Professor C.R. Daniel III [Citation ends]. Chronic paronychia represents barrier damage to the protective nail tissues, including the cuticle and the proximal and lateral nail folds.

[Figure caption and citation for the preceding image starts]: Chronic paronychia From the collection of Dr N.J. Jellinek and Professor C.R. Daniel III [Citation ends]. The altered nail barrier predisposes the nail to irritant dermatitis, most importantly from water, soap, chemicals, and microbes. Avoidance of such irritants is the hallmark of treatment.

It is usually on the surface and does not involve deeper structures of the hand or finger.

However, if treatment is delayed, or if the infection is severe, the prognosis is not as good. Message Boards flexor tenosynovitis:  purulent material resides within the flexor tendon sheath. If paronychia doesn't get better after a week or so, call your doctor. You'll want to call a doctor right away if you have an abscess (a pus-filled area in the skin or under the nail) or if it looks like the infection has spread beyond the area of the nail. the initial examiner may underestimate the severity of the wound, as it is usually small (the size of an incisor tooth or smaller, eg 3mm) with clean edges Permalink Children's Vaccines Chronic paronychia responds slowly to treatment. Resolution usually takes several weeks or months, but the slow improvement rate should not discourage physicians and patients. In mild to moderate cases, nine weeks of drug treatment usually is effective. In recalcitrant cases, en bloc excision of the proximal nail fold with nail avulsion may result in significant cure rates. Successful treatment outcomes also depend on preventive measures taken by the patient (e.g., having a water barrier in the nail fold). If the patient is not treated, sporadic, self-limiting, painful episodes of acute inflammation should be expected as the result of continuous penetration of various pathogens. seborrheic dermatitis | infection under nail seborrheic dermatitis | paronychia causes seborrheic dermatitis | paronychia define
