REVIEW
Christopher C Mills, E A Kolb, Valerie B Sampson
Preclinical and clinical development of agents that inhibit cell-cycle progression have brought an understanding of the feasibility of targeting various cell-cycle regulators in patients with cancer. Small molecule inhibitors targeting key proteins that participate in cell-cycle progression including the cyclin-dependent kinases and checkpoint kinases induce cell-cycle arrest and apoptosis in neoplastic cells. Early phase I studies demonstrate targeted inhibitors can be administered safely in adult and pediatric cancer patients, but these agents generally show limited clinical benefits as single agents...

Background: Invasive group A Streptococcus (GAS) disease has an incidence in high-income countries of 3 to 5 per 100000 per annum and a case-fatality ratio of 10% to 15%. Although these rates are comparable to those of invasive meningococcal disease in Australia before vaccine introduction, invasive GAS disease currently requires reporting in only 2 jurisdictions. Methods: Data were collected prospectively through active surveillance at the Royal Children's Hospital, Melbourne (October 2014 to September 2016)...

The pediatric population is continually at risk of developing infectious and inflammatory diseases. The treatment for infections, particularly gastrointestinal conditions, focuses on oral or intravenous rehydration, nutritional support and, in certain case, antibiotics. Over the past decade, the probiotics and synbiotics administration for the prevention and treatment of different acute and chronic infectious diseases has dramatically increased. Probiotic microorganisms are primarily used as treatments because they can stimulate changes in the intestinal microbial ecosystem and improve the immunological status of the host...

BACKGROUND: Human milk has multiple benefits for human health; however, rates of infants receiving human milk at discharge in Canadian neonatal intensive care units (NICUs) are far below recommendations of the Baby Friendly Hospital Initiative supported by the Canadian Pediatric Association. Mothers of infants requiring NICU care usually need to express their milk, especially mothers of premature infants, since for some time their infant is unable to feed directly at the breast. Expressing human milk for an extended period can be challenging for mothers...

The mucopolysaccharidoses are a set of rare, inherited conditions that can have a catastrophic impact on those affected and their families. Because of the rarity of these disorders, little is known regarding the challenges faced by families of those affected and what coping mechanisms are commonly used. Coping is a way to manage demands that occur in one's environment or within oneself. Medical social workers historically have facilitated this process while providing support to patients who are responding to pressures of their diagnosis and the system...

OBJECTIVES: The objective of this study was to describe coping mechanisms used by adolescents during emergency treatment. METHODS: A convenience sample of adolescent patients (aged 12-18 years) was surveyed in our large (87,000 annual visits) urban academic pediatric emergency department (ED) with an adapted Adolescent Coping Orientation for Problem Experiences survey. Parents were surveyed about their perceptions of their child's coping mechanisms. Participants were excluded if they were non-English speaking, in police custody, had altered mental status, or were hemodynamically unstable...

The oncogenic mechanisms driven by aberrantly expressed transcription factors in T-cell acute leukemia (T-ALL) are still elusive. MicroRNAs (miRNAs) play an important role in normal development and pathologies. Here, we examined the expression of 738 miRNA species in 41 newly diagnosed pediatric T-ALLs and in human thymus-derived cells. We found that expression of 2 clustered miRNAs, miR-125b/99a, peaks in primitive T cells and is upregulated in the T leukemia homeobox 3 (TLX3)-positive subtype of T-ALL. Using loss- and gain-of-function approaches, we established functional relationships between TLX3 and miR-125b...

There is a growing interest in the use of percutaneously delivered ventricular assist devices (PVAD) in the pediatric patient population. A 16 year old female and 18 year old male both status post heart transplantation presented with evidence of graft rejection and acute severe global systolic and diastolic heart failure necessitating hemodynamic catheterization and inotropic support. Both underwent percutaneous Impella CP LVAD (Abiomed, Danvers, MA) placement with close monitoring of right ventricular function...

Oncology products developed for adult cancers often receive full waivers of pediatric studies. This analysis retrospectively identified products with potential pediatric development opportunities despite a full waiver. Initial pediatric study plans submitted to the US Food and Drug Administration from 2012 to 2016 for oncology products with plans to request full waivers of pediatric studies were reviewed to determine if a scientific rationale existed for pediatric evaluation based on the molecular mechanism of action (MOA), clinical experience, nonclinical evidence, or published genome sequencing data...

BackgroundReverse electron transport (RET) driven by the oxidation of succinate has been proposed as the mechanism of accelerated production of reactive oxygen species (ROS) in post-ischemic mitochondria. However, it remains unclear whether upon reperfusion, mitochondria preferentially oxidase succinate.MethodsNeonatal mice were subjected to Rice-Vannucci model of hypoxic-ischemic brain injury (HI) followed by assessment of Krebs cycle metabolites, mitochondrial substrate preference, and H2O2 generation rate in the ischemic brain...

OBJECTIVES: Although clinical and pharmacologic guidelines exist for the practice of cardiopulmonary resuscitation in children (Pediatric Advanced Life Support), the practice of extracorporeal cardiopulmonary resuscitation in pediatric cardiac patients remains without universally accepted standards. We aim to explore variation in extracorporeal cardiopulmonary resuscitation procedures by surveying clinicians who care for this high-risk patient population. DESIGN: A 28-item cross-sectional survey was distributed via a web-based platform to clinicians focusing on cardiopulmonary resuscitation practices and extracorporeal membrane oxygenation team dynamics immediately prior to extracorporeal membrane oxygenation cannulation...

Technological innovations in pediatric extracorporeal life support circuits can reduce system-related complications and may improve patients' outcome. The Deltastream DP3 (Medos Medizintechnik AG, Stolberg, Germany) is a novel rotational pump with a diagonally streamed impeller that can be used over a broad range of flows. We collected patient data from seven pediatric centers to conduct a retrospective cohort study. We examined 233 patients whose median age was 1.9 (0-201) months. The DP3 system was used for cardiopulmonary support as veno-arterial extracorporeal membrane oxygenation (ECMO) in 162 patients...

Globally 1.8 million children are living with human immunodeficiency virus (HIV), yet only 51% of those eligible actually start treatment. Research and development (R&D) for pediatric antiretrovirals (ARVs) is a lengthy process and lags considerably behind drug development in adults. Providing safe, effective, and well-tolerated drugs for children remains critical to ensuring scale-up globally. We review current approaches to R&D for pediatric ARVs and suggest innovations to enable simplified, faster, and more comprehensive strategies to develop optimal formulations...

On the day of his birth in 1971, David Vetter was "temporarily" placed in a sterile isolator to wait for a bone marrow donor who would cure his Severe Combined Immunodeficiency Syndrome. After enduring 12 years in isolation, David, now known to the world as "The Boy in the Bubble", received a bone marrow transplant from his unmatched sister and died 4 months later. Like Severe Combined Immunodeficiency Syndrome, pediatric heart failure is a rare and life-threatening condition for which organ transplantation is often the only option for survival...

We report an unusual presentation of a large left atrial myxoma in an eight-year-old girl who presented with the sudden onset of chorea. This case illustrates the fact that the presentation of chorea in nonendemic areas for rheumatic fever should raise suspicion for a myxoma. The chorea resolved soon after removal of the myxoma, supporting the hypothesis of an immune-mediated mechanism, or manifestation of paraneoplastic syndrome secondary to the myxoma.

BACKGROUND: Historically, the "temporary" or short-term ventricular assist device (VAD) was used only as a quick bridge to recovery for children with an acute process. In the current era, the devices that were originally used for temporary support are now being used to support children for longer durations and for a variety of indications. In this study we aimed to describe the overall use, patients' characteristics and outcomes of "temporary" VAD use in children. METHODS: The Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS) is a National Institutes of Health-supported national registry for United States Food and Drug Administration-approved VADs in patients <19 years of age at the time of VAD implantation (either durable or temporary VAD)...

BACKGROUND: The treatment of advanced heart failure in children and infants poses a serious management problem. Heart failure in that patient group is usually of congenital etiology. The treatment schedules for pediatric patients are in most cases adapted from the guidelines for treatment of adults. Up to 2009, the treatment of that extremely difficult group of patients was limited to pharmacological therapy and occasional heart transplantations. Constantly increasing problems with recruiting donors, especially for the pediatric group, contribute to the fact that mechanical support with the use of ventricular assist devices is for many children the only chance to survive the period of waiting for a heart donor...
