Intoxicatie van een zuigeling door een Dieffenbachia

Plant poisoning is becoming an increasingly common reason to consult a doctor. A 7-month-old infant was sent to the emergency room by her general practitioner with a suspected apparent life-threatening event (ALTE). Her parents reported the sudden development of fluctuating restlessness and listlessness, superficial breathing, vomiting, drowsiness and episodes of loss of consciousness. On physical examination we saw a pale, listless and variably responsive girl. During admission for observation, she improved within a few hours, although she had one episode of blood admixture with the stool. After discharge from hospital, the infant's grandmother suggested that the symptoms could be due to poisoning from a Dieffenbachia plant. The literature supports this explanation. Young parents and doctors appear to know little about plant toxicity in general and Dieffenbachia in particular. In small children with poorly-understood symptoms, the possibility plant poisoning should be considere

FiO2 predicts outcome in infants with respiratory syncytial virus-induced acute respiratory distress syndrome

Respiratory syncytial virus (RSV) infection can progress to acute respiratory distress syndrome (ARDS) in infants. ARDS is a life-threatening condition that is characterized by severe hypoxemia, defined as PaO(2)/FiO(2) ratio <300 mmHg. This ratio is used in many trials as the sole oxygenation criterion for ARDS. Recently, however, it has been shown in adults with ARDS that FiO(2), independently of the PaO(2)/FiO(2) ratio predicts mortality. Because epidemiology and outcome of ARDS differ strongly between children and adults, we determined if FiO(2) on admission (baseline FiO(2)) independently predicted the duration of mechanical ventilation (MV) and length of stay (LOS) in the pediatric intensive care unit (PICU) in infants with RSV-induced ARDS. Retrospective observational study. A 14-bed pediatric intensive care unit. One hundred twenty-nine mechanically ventilated infants with RSV-induced ARDS. None. Independent predictors for outcome, including baseline FiO(2) and PEEP, were analyzed using the cox regression model. Endpoints were duration of MV and LOS in the PICU. A higher baseline FiO(2) was independently associated with a longer duration of MV (HR 0.12, CI 0.02-0.87, P = 0.036) and increased LOS in the PICU (HR 0.09, CI 0.01-0.57, P = 0.023). Neither baseline PEEP nor PaO(2)/FiO(2) ratio correlated with outcome. FiO(2) level independently predicted outcome in infants with RSV-induced ARDS, whereas both PEEP and the PaO(2)/FiO(2) ratio did not. This suggests that FiO(2) should be taken into account in defining disease severity in infants with RSV-induced ARD
