Renal artery embolization in a child with delayed hemodynamic instability from penetrating knife wound.

Penetrating laceration injury in the pediatric population may present as an acute or delayed life-threatening injury. Although emergent intra-arterial embolization is commonly utilized in adults, few cases have been reported for children. Surgical treatment for severe renal laceration injuries may require complete nephrectomy; an unfortunate outcome for a pediatric patient if a renal-preserving alternative is feasible. We present a case of penetrating renal laceration in a 10-year-old boy treated with intra-arterial embolization of the lacerated dominant renal artery and subsequent renal perfusion by an uninjured accessory renal artery allowing for renal preservation.

[Necrosis of maxilla secondary to purpura fulminans. A case report]. / Nécrose de l'os maxillaire compliquant un purpura fulminans. À propos d'un cas.

Purpura fulminans in infants is a rare, life-threatening condition mostly due to Neisseria meningitides. The condition is often fatal unless there is early recognition of the clinical symptoms, prompt diagnosis, and judicious replacement therapy. We observed a case of maxilla necrosis in a 5-month-old infant due to purpura fulminans. An acute necrotic process affecting the maxilla with denudation of bone and spontaneous exfoliation of teeth was noted. After 2 months, the patient was free of symptoms. To our knowledge, this is the first case report of necrosis of the maxilla secondary to a purpura fulminans. Prompt diagnosis and prompt medical intervention are necessary to avoid such complications.
