The infection resides in synovial or periarticular tissues and is usually bacterial-in younger adults, frequently. read more, infectious arthritis Acute Infectious Arthritis Acute infectious arthritis is a joint infection that evolves over hours or days. The cause is usually unknown, but trauma, repetitive or acute, may contribute, as may infection and crystal-induced disease.

Symptoms include local pain, tenderness, warmth, and swelling (if abscesses are near the skin. read more, abscess Abscesses Abscesses are collections of pus in confined tissue spaces, usually caused by bacterial infection. Common symptoms are localized bone pain and tenderness with constitutional symptoms (in acute. Infections include cellulitis Osteomyelitis Osteomyelitis is inflammation and destruction of bone caused by bacteria, mycobacteria, or fungi. Infections are the most common complications of pressure injury. High bacteria counts within the wound can hinder tissue healing. Pressure injuries are a reservoir for hospital-acquired antibiotic-resistant microorganisms. The updated NPIAP staging system also includes definitions for unstageable, deep-tissue, medical device-related, and mucosal membrane pressure injuries ( 1 Staging definition reference Pressure injuries are areas of necrosis and often ulceration (also called pressure ulcers) where soft tissues are compressed between bony prominences and external hard surfaces. Similarly, the scale does not imply that healing progresses from stage 4 through stage 1. Thus, a small injury may in fact represent extensive subcutaneous necrosis and damage. In a rapidly developing pressure injury, subcutaneous tissue can become necrotic before the epidermis erodes. Sometimes, the first sign is a deep, necrotic stage 3 or 4 injury. That is, pressure injuries do not always manifest as stage 1 and then progress to higher stages. However, the numerical staging does not imply linear progression of pressure injuries.
The most widely used system is from the National Pressure Injury Advisory Panel (NPIAP), which classifies pressure injuries into four stages (1 to 4) according to the extent of soft-tissue damage. Postphlebitic (postthrombotic) syndrome is symptomatic chronic.
