Health & Balance Finger Infection Leadership How to treat an infected hangnail Of course, we sometimes see patients at a second presentation, after simple therapies have failed. It is probably worth considering both antibiotic therapy for those patients – although we can discuss with them the risks and benefits of antibiotic therapy in an evidence-light area. I only really consider oral antibiotics in the presence of associated cellulitis or in immunosuppressed patients as simple paronychia will improve as soon as the pus is released. Antibiotics with Staphylococcal cover, such as flucloxacillin, are a reasonable first line therapy although it might be worth sending some of that pus off for culture if you can and instead prescribing co-amoxiclav or clindamycin as MRSA does occur and anaerobes may be responsible in nail-biters and finger- or thumb-suckers. Just to reiterate, sending a pus swab off if you’re treating with antibiotics (and perhaps even if you aren’t) might help you further down the line. Recommended for You Felon: The fingertip is swollen and painful. The swelling usually develops over several days and is located in the pad area of the fingertip. The area will have a throbbing pain and be painful to the touch. The area is usually red, and a visible collection of pus may be seen under the skin. The swollen area may have a portion that feels soft as if it contains fluid. As the swelling continues, the area may become tense or hard to the touch.

Dr. Rigopoulos received his medical degree from the University of Athens Medical School and completed a dermatology and venereology residency at Andreas Sygros Hospital.... First Trimester 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 External resources Any previous injuries to the area? swab for Tzanck smear (acute, herpetic) Avoid finger sucking 160 mg/800 mg orally twice daily for seven days A nail infection, or paronychia, is an infection of the skin that surrounds a fingernail. The infected tissue can be tender and painful with swelling. Paronychia is considered acute if it lasts less than 6 weeks, or chronic if it lasts longer.

Candida albicans and/or Pseudomonas may be cultured. Treating the underlying dermatitis is very important: avoidance of further irritants together with emollient use is a good start. Topical steroids are first-line therapy but culture is really important here: steroids are usually given with topical antifungal but oral antifungal such as itraconazole or fluconazole may be indicated if C.albicans is isolated. Medscape Nail Structure and Function You can avoid chronic paronychia by keeping your hands dry and free from chemicals. Wear gloves when working with water or harsh chemicals. Change socks at least every day, and do not wear the same shoes for two days in a row to allow them to dry out completely. 100 mg orally once daily for seven to 14 days Home Peer reviewers VIEW ALL  Italiano Antibiotics (oral) Gastro Noninfectious causes of paronychia include contact irritants and excessive moisture. Clinically, paronychia presents as an acute or chronic (longer than six weeks' duration) condition. People with occupations such as baker, bartender and dishwasher seem predisposed to developing chronic paronychia. Treatment may consist of warm-water soaks, antimicrobial therapy or surgical intervention. RxList Risk factors include repeatedly washing hands and trauma to the cuticle such as may occur from biting. In the context of bartending, it is known as bar rot.[4] "Opportunities do not come with their values stamped upon them." Waltbie Davenport Babcock Paddington Healthy Clinicians 21.

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 PRINT Health A-Z Home Chronic paronychia is a chronic irritant dermatitis of the periungual tissues resulting from barrier damage to the protective nail tissues, including the cuticle and the proximal and lateral nail folds. seborrheic dermatitis | how to drain pus from finger seborrheic dermatitis | infected fingernail cuticle seborrheic dermatitis | infected hangnail pictures
