Targeted inhibition of Anaplastic Lymphoma Kinase (ALK) is a successful approach for the treatment of many ALK-aberrant malignancies, however the presence of resistant mutations necessitates both the development of more potent compounds and pharmacodynamic methods with which to determine their efficacy. We describe immunoassays designed to quantitate phosphorylation of ALK, and their use in preclinical models of neuroblastoma, a pediatric malignancy in which gain-of-function ALK mutations predict a poor overall outcome to conventional treatment...

BACKGROUND: The majority of pediatric surgeries are performed in a day surgery setting. The rate of adverse postoperative outcomes and the factors that influence them are poorly described in the Canadian setting. Concerns about the safety of adenotonsillectomy (AT) have been raised. The objective of this Ontario-based study was to determine the rates and risks of hospital readmission, emergency department (ED) visits, or deaths within 30 days following common pediatric surgeries, with an emphasis on AT...

Pediatric spinal meningiomas are very rare. Most studies on pediatric spinal meningiomas are case reports with literature reviews. This study presented a surgical series of 14 pediatric patients with histologically proven sporadic spinal meningiomas, including 5 WHO grade II tumors. In this series, there were 9 male and 5 female patients with a mean age of 11.1 years. Seven tumors were located in the cervical spine, 5 in the thoracic spine, and 2 in the lumbar spine. Gross total resection (GTR) of the tumor with a well-demarcated dissection plane was achieved in 11 cases, subtotal resection was achieved in 2 cases, and partial resection was performed in 1 case...

Magnetic resonance imaging (MRI) is the workhorse modality in pediatric neuroimaging because it provides excellent soft-tissue contrast without ionizing radiation. Until recently, studies were uninterpretable without sedation; however, given development of shorter sequences, sequences that correct for motion, and studies showing the potentially deleterious effects of sedation on immature laboratory animals, it is prudent to minimize sedation when possible. This manuscript provides basic guidelines for performing pediatric neuro MRI without sedation by both modifying technical factors to reduce scan time and noise, and using a multi-disciplinary team to coordinate imaging with the patient's biorhythms...

Mini-tablets have potential applications as a flexible drug delivery tool in addition to their generally perceived use as multi-particulates. That is, mini-tablets could provide flexibility in dose finding studies and/or allow for combination therapies in the clinic. Moreover, mini-tablets with well controlled quality attributes could be a prudent choice for administering solid dosage forms as a single unit or composite of multiple mini-tablets in patient populations with swallowing difficulties (e.g., pediatric and geriatric populations)...

Background For several years the German healthy child clinics program has been a highly appreciated preventive measure and is subject to constant development. However, attendance depends on the families' sociodemographic situation. Findings are documented in a medical checkup booklet (the so-called Gelbes Heft). Currently, there is no procedure to use the data collected for epidemiological purposes nor to evaluate the pediatric prevention measures in Germany. Methods Between 2011 and 2016, we recruited 3480 study participants for our population-based cohort study LIFE Child in Leipzig...

We evaluated blood bupivacaine concentrations in children having a single-shot sciatic and continuous femoral blocks after anterior cruciate ligament repair. Dried blood spot samples were analyzed for bupivacaine levels at 0, 5, 15, 30, 60, and 120 minutes and 4, 24, and 48 hours. The highest 99% upper confidence interval limit was 135 ng/mL at the 4-hour evaluation point. The 99% upper confidence interval was below potentially toxic levels (1500 ng/mL) across all sampling times. The risk of local anesthetic toxicity in pediatric patients receiving single-shot sciatic and continuous femoral nerve blocks is very low...

BACKGROUND: Multiple organ failure (MOF) is a major contributor to morbidity and mortality in burned children. While various complications induced by electrical injuries have been described, the incidence and severity of single organ failure (SOF) and MOF associated with this type of injury are unknown. The study was undertaken to compare the incidence and severity of SOF and MOF as well as other complications between electrically and thermally burned children. PATIENTS AND METHODS: Between 2001 and 2016, 288 pediatric patients with electrical burns (EB; n = 96) or thermal burns (CTR; n = 192) were analyzed in this study...

The unpredictability of seizures causes distress to patients with epilepsy and their caretakers. To date, no studies have explored seizure prediction specifically in the pediatric population. If the period of time preceding a seizure can be reliably identified, either by child or caretaker, there may be a role for pre-emptive interventions. The aim of this study was to investigate caretaker seizure prediction. A questionnaire was distributed to caretakers of patients with epilepsy. The patients were 0-21years old and experienced ≥1 seizure within the past year...
