Since infant botulism was first identified three decades ago, our understanding of botulinum toxins and the organisms that produce them has grown. A newer classification system now recognizes Clostridium baratii and Clostridium butyricum along with Clostridium botulinum as causative agents. ⋯ Perhaps most significantly for pediatricians and child neurologists, a specific treatment for infant botulism has just been approved. This article reviews the clinical presentation, diagnosis, and treatment of infant botulism, including human botulism immune globulin, and discusses the various organisms and toxins that cause this disease.

Neurologic outcome in children after extracorporeal membrane oxygenation: prognostic value of diagnostic tests.
This report presents the long-term (36 months) neurologic outcome in 12 neonates and 9 children who survived after extracorporeal membrane oxygenation and attempts to identify its prognostic indicators through a prospective study in the pediatric intensive care unit of a university hospital. Outcome assessment, neurodevelopmental tests, electroencephalogram, auditory evoked potentials, visual evoked potentials, and somatosensory evoked potentials, cerebral sonography, or cerebral tomography were evaluated at the end of bypass and at 6, 12, 24, and 36 months after extracorporeal membrane oxygenation. "Before extracorporeal membrane oxygenation" variables (oxygenation index, pH, oxygen arterial partial pressure) and "during extracorporeal membrane oxygenation" variables (pH, oxygen arterial partial pressure, duration of bypass, clotting activated time, electroencephalogram) were also analyzed. ⋯ The most abnormal electroencephalogram during extracorporeal membrane oxygenation, the first electroencephalogram, neuroimaging score, and somatosensory evoked potentials after extracorporeal membrane oxygenation treatment were associated with negative neurologic outcome. The study documented that neonates and children treated with extracorporeal membrane oxygenation require long-term follow-up; electroencephalogram, neuroimaging score, and somatosensory evoked potentials have prognostic value for abnormal neurologic outcome.
