Review Meta Analysis
Arginine supplementation in prevention of necrotizing enterocolitis in the premature infant: an updated systematic review.
Hypoxic-ischemic injury is thought to play a significant role in necrotizing enterocolitis (NEC). Nitric Oxide (NO) is the principal inhibitory neurotransmitter in the gut and is involved in regulation of mucosal blood flow and maintenance of mucosal integrity. NO is synthesized from L-arginine by NO synthases. Our primary objective was to determine the effectiveness of supplemental L-arginine versus placebo in prevention of NEC in preterm infants ≤ 34 weeks gestational age by systematic review of published randomized controlled trials (RCTs). ⋯ L-arginine supplementation appears to be protective in prevention of NEC in preterm infants and without any significant impact on neurodevelopmental outcomes at 36 months of corrected age. With the addition of the results of one more study to the literature, an intriguing role for L-arginine supplementation continues to gain support. However, large multi-centre RCTs are needed before this can become common practice.

Clinical Trial
Effects of pediatric first aid training on preschool teachers: a longitudinal cohort study in China.
Unintentional injuries are a major cause of death among children. Data suggest that the retention of knowledge and skills about first aid declined over time. The purpose of this study was to assess the effects of pediatric first aid training among teachers. ⋯ This study demonstrated that the acquisition of knowledge, both short and long term, significantly improves. Despite appreciable decreases in knowledge long term, knowledge retention was modest but stable.

Posterior reversible encephalopathy syndrome is a potentially reversible clinicoradiologic syndrome characterized by headache, mental confusion, visual disturbances and seizures associated with posterior cerebral lesions on radiological imaging. Prompt treatment of this condition is mandatory to avoid severe irreversible complications. ⋯ Severe and isolated headache associated with arterial hypertension can be the unique clinical presentation of posterior reversible encephalopathy syndrome. This syndrome must be considered even in absence of all typical symptoms to prevent the progression of a potentially life threatening condition.

Clinical factors that affect the likelihood of abuse in children with femur fractures have not been well elucidated. Consequently, specifying which children with femur fractures warrant an abuse evaluation is difficult. Therefore the purpose of this study is to estimate the proportion of femur fractures in young children attributable to abuse and to identify demographic, injury and presentation characteristics that affect the probability that femur fractures are secondary to abuse. ⋯ Studies commonly find a high proportion of abuse among children less than 12 months old with femur fractures. The reported trauma history, physical examination findings and radiologic results must be examined for characteristics that increase or decrease the likelihood of abuse determination.

We sought to determine the extent to which physicians agree about the appropriate decision threshold for recommending magnetic resonance imaging in a clinical practice guideline for children with recurrent headache. ⋯ There is no consensus among pediatric specialists regarding the appropriate decision threshold for neuroimaging in a clinical practice guideline for children with recurrent headache. Because of the impact that individual threshold preferences may have on guidelines, these findings support the need for careful composition of guideline committees and consideration of the role of patient and family preferences. Our findings also support the need for transparency in guidelines regarding how evidence was translated into recommendations and how conflicts were resolved.
