Therapeutics in duchenne muscular dystrophy.

Duchenne muscular dystrophy (DMD) is a fatal disorder affecting approximately 1 in 3,500 live born males, characterized by progressive muscle weakness. Several different strategies are being investigated in developing a cure for this disorder. Until a cure is found, therapeutic and supportive care is essential in preventing complications and improving the afflicted child's quality of life. Currently, corticosteroids are the only class of drug that has been extensively studied in this condition, with controversy existing over the use of these drugs, especially in light of the multiple side effects that may occur. The use of nutritional supplements has expanded in recent years as researchers improve our abilities to use gene and stem cell therapies, which will hopefully lead to a cure soon. This article discusses the importance of therapeutic interventions in children with DMD, the current debate over the use of corticosteroids to treat this disease, the growing use of natural supplements as a new means of treating these boys and provides an update on the current state of gene and stem cell therapies.

Infant botulism, type F, presenting at 54 hours of life.

We report a case of botulism in a 54-hour-old infant with rapidly progressive fulminant paralysis and rapid spontaneous recovery atypical for infant botulism. Clostridium baratii and type F botulinum neurotoxin were isolated from the patient's stool. This unique presentation with rapid recovery is consistent with pharmacokinetics of type F botulinum neurotoxin. Interestingly, a muscle biopsy also revealed pathologic changes early in the disease course. This article reports the youngest known case of infant botulism and only the third reported case of this disease caused by type F neurotoxin. Botulism should be considered in patients of any age with subacute or acute neuromuscular weakness.

Recent advances in infant botulism.

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. Recently, increasing therapeutic use of botulinum toxins has sparked substantial new research into their mechanisms of action. This research, and some case reports from infants sickened by unusual botulinum toxins suggest that disease caused by different toxin types may result in varying clinical presentations. 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.
