Study Notes
Skin and Soft Tissue Infections Summary
- Surgical site infections (SSI) are classified as superficial, deep/incisional, or organ/space, with Staphylococcus aureus being the most common pathogen.
- SSI prevention includes optimizing risk factors, such as diabetes mellitus, and ensuring proper skin asepsis and antibiotic prophylaxis during surgery.
- A case study presents a patient with erythema and tenderness around a wound after bowel surgery, later diagnosed with Staphylococcus epidermidis, leading to an organ/space SSI.
- Diabetic foot ulcers require appropriate wound cleaning and debridement before taking a superficial swab for accurate results.
- A patient with a deepened, sloughy-looking diabetic foot ulcer and signs of sepsis requires an appropriate antimicrobial regime, such as Piperacillin-tazobactam or Vancomycin.
- Viral skin infections include warts, cold sores, and hand, foot & mouth disease, caused by Human Papilloma Virus (HPV) in various forms, with different treatment options.
- Fungal skin infections such as Candida, ringworm, and Pityriasis versicolor are common and require specific treatment.
- Parasitic skin infestations like scabies and lice have characteristic clinical features and require specific treatments, such as topical permethrin for scabies.
- A nurse with itchy lesions on her fingers, working in a nursing home, is likely to be diagnosed with scabies, requiring further information and specific treatment, as well as preventive measures such as washing clothes.
- Skin and soft tissue infections can arise from bacterial, viral, fungal, or parasitic causes, with examples like necrotising fasciitis, herpes, Candida, and scabies.
- Bacterial causes of skin infections are often found on the skin or respiratory tract, and common infections include impetigo, carbuncles, and healthcare-associated SSI.
- Warts, tinea, and scabies are relatively common viral, fungal, and parasitic infections, respectively, requiring specific treatment.
