A life-threatening situation due to a spider bite : a non-infectious necrotizing fasciitis.

We present the case of a healthy patient who sustained a spiderbite in the elbow and developed a non-infectious necrotizing fasciitis in the affected limb. Female patient aged 24 pain reported a spiderbite received some 72 h previously in Mexico (the spider was identified as a brown recluse spider-Loxosceles reclusa). Under the suspected diagnosis of necrotizing fasciitis urgent surgery was indicated. During her hospital stay, the patient required three additional surgical procedures, and was discharged from hospital 30 days after admission. Spider bites in the limb may be limb-threatening and life-threatening. Emergency doctors should be aware of this possibility, because spiders can be unintentionally transported all over the world.

Hemodynamic Instability after Low-Energy Thigh Contusion Caused by Injury to the Femoral Artery: A Case Report and Literature Review.

Acute vascular injuries have been described in relation to high-energy trauma accidents or in patients undergoing surgery in the femoral area. We describe a healthy patient who sustained a direct, low-energy contusion in the thigh and presented haemodynamic instability. Arteriography was used to locate the point of bleeding, and embolisation and vessel occlusion were carried out to stop the haemorrhage. The genetic study identified the COL3A1 gene mutation; accordingly, the patient was diagnosed with the Ehlers-Danlos syndrome type IV (vascular type).
