Featured content In flexor tenosynovitis, the infection is within the flexor tendon sheath. 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.

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).

Paronychias are localized, superficial infections or abscesses of the perionychium (epidermis bordering the nails). Paronychial infections develop when a disruption occurs between the seal of the proximal nail fold and the nail plate that allows a portal of entry for invading organisms. 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). Diagnostic investigations Components of the nail complex include the nail bed (matrix), the nail plate and the perionychium. The nail bed lies beneath the nail plate and contains the blood vessels and nerves. Within the nail bed is the germinal matrix, which is responsible for the production of most of the nail volume, and the sterile matrix. This matrix is the “root” of the nail, and its distal portion is visible on some nails as the half-moon–shaped structure called the lunula.1 The nail plate is hard and translucent, and is composed of dead keratin.2 The plate is surrounded by the perionychium, which consists of proximal and lateral nail folds, and the hyponychium, the area beneath the free edge of the nail1 (Figure 1).

Chronic paronychia: Causes include habitual hand washing, extensive manicure leading to destruction of the cuticle, which allows penetration of different irritant or allergic ingredients and/or different bacteria and/or yeast.

Usually, the area will need to be surgically opened and all debris and infected material removed. Because of the intricate nature of the fingers and hands, a hand surgeon will usually perform this procedure. After surgery, several days of IV antibiotics will be required followed by a course of oral antibiotics. Etiology: infection with group A hemolytic streptococci; less commonly also with Staphylococcus aureus Anatomy of a nail In patients with acute paronychia, only one nail is typically involved.10 The condition is characterized by rapid onset of erythema, edema, and discomfort or tenderness of the proximal and lateral nail folds,11 usually two to five days after the trauma. Patients with paronychia may initially present with only superficial infection and accumulation of purulent material under the nail fold, as indicated by drainage of pus when the nail fold is compressed12,13 (Figure 2). An untreated infection may evolve into a subungual abscess, with pain and inflammation of the nail matrix.11 As a consequence, transient or permanent dystrophy of the nail plate may occur.10 Pus formation can proximally separate the nail from its underlying attachment, causing elevation of the nail plate.10,11 Recurrent acute paronychia may evolve into chronic paronychia.7,12 Tennis elbow (lateral epicondylitis) is a common condition that occurs when the outer tendons of the elbow swell or… Classic signs of inflammation Thank you, , for signing up.

Damaging your cuticles gives bacteria a way to get into your skin and cause an infection. There are multiple causes of both acute and chronic paronychia. The underlying cause of each is bacteria, Candida yeast, or a combination of the two agents. pus-filled blisters Media type: Photo By contrast, chronic paronychia is most frequently caused by repeated exposure to water containing detergents, alkali, or other irritants. This can lead to the swelling and gradual deterioration of the epidermal layer. Unlike acute paronychia, most chronic infections are caused by the fungus Candida albicans and other fungal agents.
