Extensive direct spreading of "groin hit"-related soft tissue infections: a report of three cases. Forensic Sci Med Pathol 2023; 19:117-120.

Abstract
We present fatal extensive soft tissue infections, a consequence of groin heroin injection, in three subjects, who were 27, 34, and 39 years old and had a history of over 10-, 15-, and 5-years of heroin injection (cases 1, 2, and 3, respectively). In all cases, the first symptoms of the infection appeared at least a week prior, with rapid deterioration on the last day. The hallmark was a disproportion between external and internal findings in the affected thighs. The latter presented as extensively spread suppurative inflammation with soft tissue necrosis. In case 1, subtle skin erythema was present in the left groin, with a wound suggestive of a recent abscess incision and injection-related scarring. However, dissection revealed that inguinal regions and deep soft tissue (including the muscle sheets) of the left thigh, gluteal region, and lower third of the anterior abdominal wall were inflamed with pus, alongside fibrinopurulent peritonitis. Case 2 had pronounced erythema and swelling of the thigh and knee. Diffuse suppuration was observed upon dissection in the inguinal regions, which extended into the iliopsoas muscles, with soft tissue and muscle necrosis. In the abdominal cavity, we detected 150 mL of serofibrinous exudate. Only case 3 had a prominent, 4 × 3.5-cm necrotic skin defect through which pus spontaneously drained. In contrast to the other two, although extensive pus collection within predominantly necrotic thigh's soft tissue was present, the inflammation did not expand above the inguinal ligament, and peritonitis was not observed. Toxicology analysis excluded acute heroin intoxications.

Abstract
Background Necrotizing soft tissue infections (NSTIs) is severe surgical infections which can occur following trauma or abdominal surgery. NSTIs secondary to gastrointestinal (GI) fistula is a rare but severe complication. Methods A retrospective cohort study was performed on all subjects presenting with GI fistulas associated NSTIs were included. Clinical characteristics, microbiological profile, operations performed, and outcomes of patients were analyzed. Results Between 2014 and 2017, 39 patients were finally enrolled. The mean age were 46.9 years and male were the dominant. For the etiology of fistula, 25 (64.1%) of the patients was due to trauma. Overall, in-hospital death occurred in 15 (38.5%) patients. Microbiologic findings were obtained from 31 patients and Klebsiella pneumoniae was the most common species (41.0%). Eight patients were treated with an open abdomen; negative pressure wound therapy was used in 33 patients and only 2 patients received hyperbaric oxygen therapy. Younger age and delayed abdominal wall reconstruction repair were more common in trauma than in non-trauma. Non-survivors had higher APACHE II score, less source control< 48 h and lower platelet count on admission than survivors. Multiple organ dysfunction syndrome, multidrug-resistant organisms and source control failure were the main cause of in-hospital mortality. Conclusions Trauma is the main cause of GI fistulas associated NSTIs. Sepsis continues to be the most important factor related to mortality. Our data may assist providing enlightenment for quality improvement in these special populations.
