Health Library Ingrown Toenails Other entities affecting the fingertip, such as squamous cell carcinoma of the nail29,30 (Figure 5), malignant melanoma, and metastases from malignant tumors,31 may mimic paronychia. Physicians should consider the possibility of carcinoma when a chronic inflammatory process is unresponsive to treatment.30 Any suspicion for the aforementioned entities should prompt biopsy. Several diseases affecting the digits, such as eczema, psoriasis, and Reiter syndrome, may involve the nail folds.10 Paediatric trauma is different. #RCEM15: Ross Fisher The other common management strategy is to excise a portion of the nail to allow pus drainage. If you are going to be cutting things, do perform a ring or digital block first and allow time for the local anaesthetic to work. Remember from your vast pharmacology knowledge that most local anaesthetics as weak bases and are unable to cross lipid membranes in acidic conditions – so local infiltration of infected tissues does not work (read more here). 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. Anatomic relationships of flexor sheaths to deep fasical spaces should be kept in mind. Contiguous spread can result in a “horseshoe abscess”: from small finger flexor sheath to the thumb flexor sheath via connection between the radial and ulnar bursae.

If the infection is mild, then only oral antibiotics may be needed. If more severe, a hand surgeon should evaluate the wound and IV antibiotics begun. Often these wounds will require incision and drainage followed by a course of antibiotics. Pregnancy Family & Pregnancy The symptoms of both acute and chronic paronychia are very similar. They’re largely distinguished from each other by the speed of onset and the duration of the infection. Chronic infections come on slowly and last for many weeks. Acute infections develop quickly and don’t last long. Both infections can have the following symptoms: Diagnosis of chronic paronychia is based on physical examination of the nail folds and a history of continuous immersion of hands in water10; contact with soap, detergents, or other chemicals; or systemic drug use (retinoids, antiretroviral agents, anti-EGFR antibodies). Clinical manifestations are similar to those of acute paronychia: erythema, tenderness, and swelling, with retraction of the proximal nail fold and absence of the adjacent cuticle. Pus may form below the nail fold.8 One or several fingernails are usually affected, typically the thumb and second or third fingers of the dominant hand.13 The nail plate becomes thickened and discolored, with pronounced transverse ridges such as Beau's lines (resulting from inflammation of the nail matrix), and nail loss8,10,13 (Figure 4). Chronic paronychia generally has been present for at least six weeks at the time of diagnosis.10,12 The condition usually has a prolonged course with recurrent, self-limited episodes of acute exacerbation.13 Simon Carley on the future of Emergency Medicine Anemia Depending on the cause of the infection, paronychia may come on slowly and last for weeks or show up suddenly and last for only one or two days. The symptoms of paronychia are easy to spot and can usually be easily and successfully treated with little or no damage to your skin and nails. Your infection can become severe and even result in a partial or complete loss of your nail if it’s not treated. Tetanus prophylaxis External links[edit] Giving Facebook Twitter YouTube Instagram LinkedIn Pinterest Snapchat Don't try to puncture or cut into an abscess yourself. Doing that can lead to a more serious infection or other complications. The doctor may need to drain the abscess and possibly prescribe antibiotic medications to treat the infection. Once an abscess is treated, the finger or toe almost always heals very quickly.

This technique gives more rapid relief and more sustained drainage, especially in patients with paronychia resulting from an ingrown nail.8,17,19 Complicated infections can occur in immunosuppressed patients and in patients with diabetes or untreated infections.11,16  Preventive measures for acute paronychia are described in Table 2.3,10,13,19,20 Classification D Sex: ♀ > ♂ (3:1) 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. Do I need to take an antibiotic? DIFFERENTIAL DIAGNOSIS: Pagination These patients should be referred to hand surgeons for surgical drainage and treated with antibiotics covering Staph. aureus in the first instance. Herpetic Whitlow Then perform the same steps as above or make a small incision into the swollen skin overlying the collection of pus, with or without the addition of excision of 3-5mm of the width of the nail (note – I have never done this in clinical practice as separating the nail from the skin seems to work effectively to release pus for the patients I have seen. If you genuinely think excision of the nail might be required, this would probably be better dealt with by a hand surgeon). If you are incising you might consider putting in a wick: a thin piece of sterile gauze will suffice although the jury is out on whether this is a useful intervention in itself (I’ll be looking out for the results of this study on wick vs packing for abscess care). twitter Cellulitis: This infection is superficial, and oral antibiotics are usually sufficient. If the area is extensive or your immune system is weakened, then you may be treated in the hospital with IV antibiotics. Info Permanent deformation of the nail plate #stemlynsLIVE Red streaks appear on your skin, running from the infected area toward your body (for example, up your foot from your toes or up your hand or wrist from your fingers).
