RESUMO
Propofol infusion syndrome (PRIS) is a rare but potentially lethal complications. This disorder is triggered under unknown circumstances by a propofol infusion of more than 5 mg/kg/h for more than 48 h. PRIS is characterized by a multiorgan failure and rhabdomyolysis and is induced by a disturbance in mitochondrial long chain fatty acid oxidation. We report a 43 year-old woman who underwent brain surgery due to a vascular malformation. In the immediate postoperative period, she had an unexplained and severe lactic acidosis. During anaesthesia, she received a propofol infusion of 7 mg/kg/h that continued in the UCI at a rate of 3.5 mg/kg/h, for 8 hours more. The suspicion of PRIS motivated immediate discontinuation of propofol with rapid correction of lactic acidosis and full recovery of the patient.

El adenocarcinoma gástrico es una neoplasia poco frecuente en pacientes menores de 15 años. Se denomina tumor de Krukenberg a la metástasis ovárica secundaria a esta neoplasia, o a otras neoplasias, que histológicamente presenten células en anillo de sello y reacción sarcomatoide del estroma. Generalmente se presenta en mujeres cuya edad promedio es de 40 años sexualmente activas; su sintomatología puede derivar de la neoplasia primaria o de la metástasis ovárica. El presente artículo expone el caso de una adolescente de 14 años, que accidentalmente autopesquisa una masa pélvica bilateral. Tras estudio imagenológico se determinó su origen anexial, se realizó una laparotomía exploradora que incluyó ooferectomía bilateral, apendicectomía y linfadenectomía. La biopsia rápida informó la presencia de células en anillo de sello en dichos tejidos. En busca de la neoplasia primaria, se realizó una endoscopia digestiva alta que evidenció un adenocarcinoma gástrico con iguales características histológicas. La biopsia definitiva confirmó el diagnóstico de tumor de Krukenberg. Se describe lo que parece el caso más precoz con primario conocido reportado y se revisa la literatura.
