Patent ductus arteriosus (PDA) in preterm infants is a controversial topic in the management of preterm neonates. There are no generally accepted guidelines for diagnosis, treatment, and follow-up of PDA, and few publications have covered the whole topic or have been conclusively summarized to give a proper direction for the treating physician. Major issues remain to be clarified, both with respect to diagnosis and treatment. The definition of hemodynamic significance varies because of different use of echocardiographic criteria and uncertainty about the role of biomarkers. The detailed risks and benefits of available treatment alternatives are still under investigation. There has been a general shift in the management of PDA in preterm neonates from the "aggressive approach" to a more "conservative approach," but the effects of this strategy on morbidity in a longer time perspective are not fully known. An individualized therapeutic strategy with special emphasis on identification of hemodynamically significance seems to be the way forward. In this review we put forward the scientific background in favor of a seemingly growing body of evidence against active treatment, but we raise caution against shying away from all forms of treatment or instituting them too late. Finally, we try to integrate the current knowledge into suggestions for the management of PDA in premature infants. © 2013 Wiley Periodicals, Inc.

Adolescents and young adults (AYA) with advanced or terminal cancer have distinctive medical and psychosocial needs that may not have been adequately provided by either pediatric or adult palliative care services. A discussion group, as part of a larger workshop on AYA with cancer, was held in Toronto on March 11-13, 2010;117:-. Recommendations were as follows: Develop a specific AYA screening tool designed to detect increased anxiety or new symptoms and to initiate discussion about palliative or symptom care; Set Canadian standards for palliative care in AYA patients. These standards should be included in hospital accreditation; Involve the palliative/symptom care team early in the disease trajectory to help manage clinically important symptoms that may not be associated with imminent death; Establish specific AYA multidisciplinary palliative care teams throughout Canada that are flexible and can work in both pediatric and adult facilities, and are able to work in a "virtual" environment to support patients being cared for at home; Improve physical facilities in hospices and hospitals to meet the distinctive needs of terminally ill AYA patients; Enhance support for palliative care at home by: changing legislation to improve Compassionate Care Benefits and developing "virtual palliative care support teams". Adequate provision of AYA palliative care and symptom management services will likely confer notable benefits to AYA patients and their families, and is likely to be cost saving to the tax payer by avoiding prolonged hospitalization and promoting easier return to work for the families and caregivers.

Objective: To evaluate the role of wireless capsule endoscopy in identifying small bowel lesions in pediatric patients with newly diagnosed colonic inflammatory bowel disease (IBD) type unclassified (IBDU), and to assess whether capsule endoscopy findings result in altered patient management. Methods: Ten pediatric patients recently diagnosed with IBDU through standard investigations were recruited from the pediatric gastroenterology clinic at McMaster Children's Hospital to undergo capsule endoscopy using the Pillcam SBTM (Given Imaging) capsule. Findings consistent with a diagnosis of Crohn's disease required the identification of at least three ulcerations. Results: Three out of ten patients had newly identified findings on capsule endoscopy that met criteria for Crohn's disease. Three more patients had findings suspicious for Crohn's disease, but failed to meet the diagnostic criteria. Three additional patients had findings most consistent with ulcerative colitis, and one had possible gastritis with a normal intestine. Findings from capsule endoscopy allowed for changes in the medical management of three patients. In all ten cases, capsule endoscopy allowed for a better characterization of the type and extent of disease. No adverse outcomes occurred in the present cohort. Conclusion: This prospective study reveals that wireless capsule endoscopy is feasible, valuable, and non-invasive, offering the ability to potentially better characterize newly diagnosed pediatric IBDU cases by identifying lesions in the small bowel and reclassifying these as Crohn's disease. © 2013 Sociedade Brasileira de Pediatria.

Pediatric inflammatory bowel disease encompasses a spectrum of disease phenotype, severity, and responsiveness to treatment. Intestinal healing rather than merely symptom control is an especially important therapeutic goal in young patients, given the potential for growth impairment as a direct effect of persistent chronic inflammation and the long life ahead, during which other disease complications may occur. Corticosteroids achieve rapid symptom control, but alternate steroid-sparing strategies with greater potential to heal the intestine must be rapidly adopted. Exclusive enteral nutrition is an alternate shortterm treatment in pediatric Crohn's disease. The results of multi-center pediatric clinical trials of both infliximab and adalimumab in Crohn's disease and of infliximab in ulcerative colitis (all in children with unsatisfactory responses to other therapies) have now been reported and guide treatment regimens in clinical practice. Optimal patient selection and timing of anti-TNF therapy requires clinical judgment. Attention must be paid to sustaining responsiveness safely. © Springer Science+Business Media, LLC 2012.

Post-concussion syndrome is an aggregate of symptoms that commonly present together after head injury. These symptoms, depending on definition, include headaches, dizziness, neuropsychiatric symptoms, and cognitive impairment. However, these symptoms are common, occurring frequently in non-head injured controls, leading some to question the existence of post-concussion syndrome as a unique syndrome. Therefore, some have attempted to explain post-concussion symptoms as post-traumatic stress disorder, as they share many similar symptoms and post-traumatic stress disorder does not require head injury. This explanation falls short as patients with post-concussion syndrome do not necessarily experience many key symptoms of post-traumatic stress disorder. Therefore, other explanations must be sought to explain the prevalence of post-concussion like symptoms in non-head injury patients. Many of the situations in which post-concussion syndrome like symptoms may be experienced such as infection and post-surgery are associated with systemic inflammatory responses, and even neuroinflammation. Post-concussion syndrome itself has a significant neuroinflammatory component. In this review we examine the evidence of neuroinflammation in post-concussion syndrome and the potential role systemic inflammation plays in post-concussion syndrome like symptoms. We conclude that given the overlap between these conditions and the role of inflammation in their etiologies, a new term, post-inflammatory brain syndromes (PIBS), is necessary to describe the common outcomes of many different inflammatory insults. The concept of post-concussion syndrome is in its evolution therefore, the new term post-inflammatory brain syndromes provides a better understanding of etiology of its wide-array of symptoms and the wide array of conditions they can be seen in. © 2015 Elsevier Inc.
