1. Paronychia: Acute. Chronic. 2. Felon. 3. Herpetic Whitlow. 4. Flexor Sheath Infections. 5. Palmar Infections. 6. Dorsal Infections. 7. ‘Fight Bites’
Slide 3-

Overview Most commonly staph aureus Many infections due to multiple organisms 30-40% grow anaerobic species. Other organisms include streptococci, enterobacteria, pseudomonas, enterococci, bacteroides.
Slide 4-

Paronychia
Slide 5-

Acute Paronychia Usually presents two to five days post-trauma. Usually Staphylococcus aureus and Streptococcus pyogenes Treatment: Warm water soaks if an abscess has not formed.

Slide 7-

Chronic Paronychia Chronic inflammatory condition (>6/52) Causes thickening of the cuticle and grooving of the nail Most Commonly caused by a candidal infection Often described in middle-aged women
Slide 8-

Conservative: topical antifungal/steroid. Surgical treatment: marsupialisation of perionychium Nail removal and topical antifungal
Slide 9-

Felon Abscess of the distal pulp or phalanx pad of the fingertip.
Slide 10-

Usually penetrating trauma Most commonly affected digits are the thumb and index finger May arise when an untreated paronychia spreads into the pad of the fingertip.

Slide 12-

Herpetic Whitlow Results from autoinoculation of type 1 or type 2 herpes simplex virus into broken skin. The infection may occur as a complication of primary oral or genital herpes lesions. Health care workers exposed to oral secretions
Slide 13-

Fever, lymphadenitis, lymphadenopathy Small, clear vesicles initially are present.
Slide 14-

Flexor Sheath Infections
Slide 15-

Kanavel’s four cardinal signs: (1) uniform, symmetric digit swelling; (2) at rest, digit is held in partial flexion; (3) excessive tenderness along the entire course of the flexor tendon sheath; (4) pain along the tendon sheath with passive digit extension. Pain with passive extension is the most clinically reproducible
Slide 16-

Usually secondary trauma or puncture wound. The trauma often is at a flexor crease; this is where the tendon sheath is most superficial.
Slide 17-

Staphylococcus and Streptococcus Early: splinting, elevation, ivAx 12-24 hours no improvement → surgical intervention Early surgery in immunocompromised or diabetics.
