A Serious Complication of Illicit Silicone Injections: Latent Silicone Embolization Syndrome after Incision and Drainage of Local Injection Site.

BACKGROUND: Silicone embolization syndrome, a serious adverse effect of illicit silicone injections by laypersons, occurs when silicone particles enter the circulation and shower the lungs and other vital organs. METHODS: We review the literature on silicone embolization syndrome and describe a unique case of the syndrome that developed after a latent period of several months, upon surgical debridement of an injection site abscess. RESULTS: In the scientific literature, silicone embolization syndrome has been well described and multiple presentations have been delineated. Immediate presentation with a rapidly fatal course occurs in cases of erroneous intra-vascular injection, in which large volumes of silicone occlude pulmonary arteries and cause cor pulmonale. Insidious presentation of progressive respiratory distress and systemic inflammatory response syndrome occurs in cases of peri-vascular injection, caused by gradual vascular infiltration by smaller silicone emboli that shower pulmonary capillaries diffusely, causing alveolar hemorrhage and inflammation. Rarely, latent cases have presented months to years later upon trauma to the original site, which disrupts the sequestered siliconoma, allowing re-exposure to the immune system and the opportunity for vascular infiltration. CONCLUSIONS: To the best of our knowledge, this is the first description of silicone embolization syndrome that occurred after surgical manipulation of the site. It has important management implications for patients with a history of prior silicone injections at a site being considered for surgical intervention. Strategies for managing this potential complication include adding a regimen of daily debridement, aggressive ventilator support, and maintaining close observation in an intensive care unit (ICU) or progressive care unit (PCU) during the high-risk post-operative period. Alternatively, when possible, surgeons may avoid disruption of the siliconoma by trialing medical management of localized inflammation or using alternative procedures such as image-guided wide local excision or liposuction with fat transfer.

Battlefield casualties treated at Camp Rhino, Afghanistan: lessons learned.

BACKGROUND: Operation Enduring Freedom is an effort to combat terrorism after an attack on the United States. The first large-scale troop movement (> 1,300) was made by the U.S. Marines into the country of Afghanistan by establishing Camp Rhino. METHODS: Data were entered into a personal computer at Camp Rhino, using combat casualty collecting software. RESULTS: Surgical support at Camp Rhino consisted of two surgical teams (12 personnel each), who set up two operating tables in one tent. During the 6-week period, a total of 46 casualties were treated, and all were a result of blast or blunt injury. One casualty required immediate surgery, two required thoracostomy tube, and the remainder received fracture stabilization or wound care before being transported out of Afghanistan. The casualties received 6 major surgical procedures and 11 minor procedures, which included fracture fixations. There was one killed in action and one expectant patient. The major problem faced was long delay in access to initial surgical care, which was more than 5 hours and 2 hours for two of the casualties. CONCLUSION: Smaller, more mobile surgical teams will be needed more frequently in future military operations because of inability to set up current larger surgical facilities, and major problems will include long transport times. Future improvements to the system should emphasize casualty evacuation, en-route care, and joint operations planning between services.
