Review Case Reports
Infant botulism: two recent cases and literature review.
Infant botulism is a cause for significant pediatric morbidity in the United States, though early recognition and supportive care can greatly improve clinical outcomes. Since the approval of human botulism immune globulin by the United States Food and Drug Administration (FDA) for the treatment of infant botulism in 2003, the importance of prompt initiation of therapy has been emphasized, with clinical suspicion remaining the mainstay of diagnosis. ⋯ Each presented to the Pediatric Neurology service at our institution in Upstate New York in the spring and summer months of 2007 and were felt to be related to markedly dusty environmental conditions and the probable ingestion of C. botulinum organisms present in soil. Following this, a comprehensive review of the literature regarding infant botulism in the United States is presented, wherein the pathophysiology, clinical features, epidemiology, and treatment are discussed.

Transcranial magnetic stimulation (TMS) is a method for focal brain stimulation based on the principle of electromagnetic induction, where small intracranial electric currents are generated by a powerful, rapidly changing extracranial magnetic field. Over the past 2 decades TMS has shown promise in the diagnosis, monitoring, and treatment of neurological and psychiatric disease in adults, but has been used on a more limited basis in children. ⋯ The potential for applications of TMS in child neurology and psychiatry is significant. Given its excellent safety profile and possible therapeutic effect, this technique should develop as an important tool in pediatric neurology over the next decade.

The goal of this article is to provide a rational methodological review of studies addressing the treatment of childhood headache. In particular, the goal is to provide a review of process variables that may be associated with the efficacy of behavioral and psychological treatments for childhood headache. ⋯ A total of 9 studies were selected for the present systematic review. The findings from this study suggest that although research supports the use of behavioral treatments for headache among this patient population, process variables such as child demographics, as well as treatment characteristics such as time in treatment, may moderate treatment efficacy.

Many physicians consider examining the nervous system as one of the most difficult parts of the physical examination. Difficult and poorly cooperative children remain the most challenging group to examine accurately and completely. In this situation, the physician becomes less confident about the neurological findings and clinical evaluation. ⋯ In this review, some practical tips and techniques are presented that can be used to improve the likelihood of obtaining accurate information about the neurological status of young and difficult children. Certainly, repeated examinations and experience play an important role; however, solid knowledge, strong communication skills, accurate observational skills, and use of proper techniques are crucial for eliciting and interpreting neurological signs in difficult children. Finally, a patient and empathetic physician and supportive guiding parents are needed for a successful neurological assessment.

Periventricular white-matter injury is the major form of brain injury associated with prematurity and the leading cause of cerebral palsy in survivors of premature birth. Progress in understanding the pathogenesis of periventricular white-matter injury requires the development of animal models that are relevant to the unique physiology of the preterm human brain and that replicate the major neuropathologic features of human injury. The sheep is the most extensively studied true fetal preparation. ⋯ Oligodendrocyte maturation in the 90- to 105-day fetal sheep closely coincided with that of the preterm human during the high-risk period for white-matter injury. Hence, the immature state of the 90- to 105-day fetal periventricular white-matter is an optimal and dynamic developmental window to study the role of cellular-maturational factors in the pathogenesis of white-matter injury. We conclude with a review of the significant advantages of the instrumented fetal sheep to accelerate progress in the translation of preventive therapies for periventricular white-matter injury and cerebral palsy.
