Hemorrhagic stress ulceration in a case of appendicitis.

Hemorrhage from stress ulceration in acutely ill children is seen in association with acute respiratory failure, coagulopathy and Pediatric Risk of Mortality Score of 10 or higher. We report an unusual association of clinically significant hemorrhagic stress ulcer with appendicitis in a pediatric patient.

Extra corporeal membrane oxygenation and plasmapheresis for pulmonary hemorrhage in microscopic polyangiitis.

Early initiation of extracorporeal membrane oxygenation to treat acute hypoxemic respiratory failure secondary to massive pulmonary hemorrhage in microscopic polyangiitis in children can be life-saving while awaiting control of the autoimmune disease process by plasmapheresis and immunosuppression.
