Pathophysiology Copyright 2012 OrthopaedicsOne  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.

Symptoms are classically present for six weeks or longer.11 Fluctuance is rare, and there is less erythema than is present in acute paronychia. Inflammation, pain and swelling may occur episodically, often after exposure to water or a moist environment. Eventually, the nail plates become thickened and discolored, with pronounced transverse ridges.6,8 The cuticles and nail folds may separate from the nail plate, forming a space for various microbes, especially Candida albicans, to invade.8 A wet mount with potassium hydroxide from a scraping may show hyphae, or a culture of the purulent discharge may show hyphae for bacteria and fungal elements. C. albicans may be cultured from 95 percent of cases of chronic paronychia.6 Other pathogens, including atypical mycobacteria, gram-negative rods and gram-negative cocci, have also been implicated in chronic paronychia (Table 1).6 Occupational Health Message Boards Educational theories you must know.

Health Permalink For most cases, the diagnosis of infection is made by history and physical exam. X-rays are a rapid and cost effective way to identify bony changes and radiopaque foreign bodies. More complex imaging studies should be reserved for situations where the diagnosis remains unclear despite adequate examination and initial treatment, or if the patient does not respond to appropriate management. Email Alerts Use rubber gloves, preferably with inner cotton glove or cotton liners 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:  Page contributions Questions & Answers Email Alerts Your Health Resources The hand is susceptible to infection by virtue of its intimate contact with the outside world, its great surface area and its propensity for injury. That is, the hand is exposed frequently to infectious organisms, and these organisms are frequently given a point of entry.

Loss of function, loss of sensation, disfigurement, or even loss of the finger is possible. DESCRIPTION A felon is an abscess on the palmar surface of the fingertip. Bacteria are normally introduced via minimal penetrating trauma, such as a splinter. 29. High WA, Tyring SK, Taylor RS. Rapidly enlarging growth of the proximal nail fold.

Time: 2018-09-16T11:55:59Z Chronic paronychia is an infection of the folds of tissue surrounding the nail of a finger or, less commonly, a toe, lasting more than six weeks.[2] It is a nail disease prevalent in individuals whose hands or feet are subject to moist local environments, and is often due to contact dermatitis.[9]:660 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.[11]:343 It can be the result of dish washing, finger sucking, aggressively trimming the cuticles, or frequent contact with chemicals (mild alkalis, acids, etc.).

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 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.
