MCQ MAHE 2000 Surgery Answer 19

The Correct Answer is A

Necrotizing fasciitis can occur after trauma or around foreign bodies in surgical wounds, or it can be idiopathic, as in scrotal or penile necrotizing fasciitis. Necrotizing fasciitis has also been referred to as hemolytic streptococcal gangrene, Meleney ulcer, acute dermal gangrene, hospital gangrene, suppurative fasciitis, and synergistic necrotizing cellulitis.

The term “Meleney’s ulcer” describes a distinct pathological entity also called progressive bacterial synergistic gangrene.When Meleney described the condition, he had no access to sophisticated culture techniques necessary to isolate fastidious anaerobic bacteria that cause the condition. However, he observed that these wounds, described exclusively in post-operative abdominal incisions, included a mixture of organisms. From his culture results, he deduced that the margin of the ulcer was advanced by the synergistic effect of two organisms growing in a hypoxic environment. Those organisms were a micro-aerophilic, non-hemolytic Streptococcus, and a hemolytic Staphylococcus aureus.
