Fat embolism syndrome secondary to injection of large amounts of soft tissue filler in the gluteal area.

There are no reports in the literature of an association between soft tissue filler (STF) injection and fat embolism syndrome (FES). The authors present the case of a 26-year-old woman who was injected in the gluteal area with approximately 200 cc of STF on each side for aesthetic purposes. After this procedure, she presented with the triad of hypoxemia, neurological impairment, and petechiae consistent with the diagnosis of FES.

[Recombinant factor VII activated in non-hemophiliac patients with acute severe hemorrhage in the intensive care unit].

Background: Severe hemorrhage is a frequent complication with multiple etiologies and high morbi-mortality observed among critically ill patients. Recombinant Factor VIla (rFVlla) constitutes a new therapeutic alternative.

Objective: Analyze the evolution in a non-hemophiliac patient group with severe hemorrhage treated with rFVlla.

[Toxic epidermal necrolysis].

Toxic epidermal necrolysis is the prototype of a proapoptotic disease characterized by system CD95 dysrregulation. Drugs constitute the main antigenic triggers. Hystopatologically it is characterized by epidermis detachment and necrosis with apoptotic keratinocytes.

[Knotting Swan-Ganz catheter in right pulmonary artery].

Knotting Swan-Ganz catheter is a rare complication of hemodynamic monitoring. This is the second case reported in Mexico in over 20 years. Identified risk factors that increase likelihood of loop formation knotting of the catheter are blind introduction and small diameter of catheter, incomplete balloon inflation before advancing it, several tries to wedge it, bending of the catheter by heat, and enlarged right heart chambers.
