Development of cellulitis or erysipelas The paronychium is a small band of epithelium that covers the medial and lateral borders of the nail. The eponychium is a small band of epithelium that covers the proximal aspect of the nail. Raising Fit Kids The Causes of Paronychia 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. Wikimedia Commons has media related to Paronychia (disease).

Unusual exposures lead to unusual bacteria: eg tropical fish aquarium workers, butchers, farmers. Soak the infected area in warm water once or twice a day for 20 minutes. Prevention 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 PROGNOSIS Equality and global health. What I learned from being a recovering racist… People with the following conditions tend to have more extensive paronychial infections and may need to be treated with a prolonged course of antibiotics: Patients suspected of having a hand infection will often undergo plain x-rays. The bony structures will typically appear normal except in very advanced infections involving the bone. Ultrasound can show loculated fluid collections, but is heavily dependent on the skill of the person performing the study. Magnetic resonance imaging, with or without gadolinium contrast, may show occult deep space infections if the clinical picture is not clear. Use of MRI is limited by cost as well as availability depending on when and where the patient is being evaluated. Finger Infection Overview Home treatments are often very successful in treating mild cases. If you have a collection of pus under the skin, you can soak the infected area in warm water several times per day and dry it thoroughly afterward. The soaking will encourage the area to drain on its own. Investigations Pagination McKnight's Senior Living Thank you 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.

A compromised immune system, such as with people living with HIV Mental Health Paronychia at Life in the Fast Lane Sign Out Simon Carley on the future of Emergency Medicine Cleveland Clinic Menu 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. Rick Body.

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.

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. Felon is an infection of the distal pulp space of the fingertip. While the cause is often unknown, minor trauma most commonly precedes infection. It is a clinical diagnosis based on the presence of local pain, swelling, induration, and erythema. Early stages of felon may be managed conservatively with analgesics and antibiotics. Later stages require incision and drainage. Complications include fingertip soft tissue necrosis and osteomyelitis. IP address: 38.107.221.217 Fungal Infections: What You Should Know Support Us Infectious flexor tenosynovitis: Four major signs often are found with this condition. First is tenderness over the flexor or palm side of the finger. This pain is found over the tendons in the finger. Second is uniform swelling of the finger. Third is pain on extending or straightening of the finger. Fourth, the finger will be held in a slightly flexed or partially bent position. These signs are called Kanavel cardinal signs. All 4 signs may not be present at first or all at once. Menu The diagnosis of acute paronychia is based on a history of minor trauma and findings on physical examination of nail folds. The digital pressure test may be helpful in the early stages of infection when there is doubt about the presence or extent of an abscess.14 The test is performed by having the patient oppose the thumb and affected finger, thereby applying light pressure to the distal volar aspect of the affected digit. The increase in pressure within the nail fold (particularly in the abscess cavity) causes blanching of the overlying skin and clear demarcation of the abscess. In patients with severe infection or abscess, a specimen should be obtained to identify the responsible pathogen and to rule out methicillin-resistant S. aureus (MRSA) infection.13 Nutrient Shortfall Questionnaire flexor tenosynovitis:  purulent material resides within the flexor tendon sheath.
