Skin grafting is absolutely C/I in which skin infection?
**Core Concept**
Skin grafting is a surgical procedure that involves transferring a layer of skin from one part of the body to another. It is a critical procedure in reconstructive surgery, but it comes with specific contraindications to ensure the success of the graft. Infections are a major concern, as they can compromise the integrity of the graft and lead to failure.
**Why the Correct Answer is Right**
Streptococcal infections, particularly those caused by Group A beta-hemolytic streptococci (GABHS), are a contraindication for skin grafting. This is because streptococci produce exotoxins that can cause tissue destruction and necrosis, which can lead to graft failure. The presence of streptococcal infections in the recipient site can also lead to the development of toxic shock syndrome, a life-threatening condition. The other options, while serious infections, do not have the same level of contraindication for skin grafting.
**Option A:** Staphylococcus infections, such as methicillin-resistant Staphylococcus aureus (MRSA), can be a concern for skin grafting, but they are not as absolute a contraindication as streptococcal infections.
**Option B:** Pseudomonas infections can cause significant morbidity, particularly in immunocompromised patients, but they are not typically a contraindication for skin grafting.
**Option D:** Proteus infections are often associated with urinary tract infections and are not typically a contraindication for skin grafting.
**Clinical Pearl / High-Yield Fact**
When considering skin grafting, it is essential to ensure that the recipient site is free of infection, particularly streptococcal infections. A thorough history, physical examination, and laboratory testing, including cultures and sensitivity testing, should be performed to rule out active infections.
**Correct Answer:** ✓ Correct Answer: C. Streptococus
