Pediatric Cannabinoid Hyperemesis: A Single Institution 10-Year Case Series.

Purpose: Cannabis hyperemesis (CH) is an under-recognized condition in patients with chronic or cyclic vomiting and who regularly use cannabis. Once thought to be rare, it is now increasingly recognized in both adults and children. We report a case series of adolescent patients with CH who presented at a single institution over 10 years.

Pediatric asthma severity scores distinguish suitable inpatient level of care for children admitted for status asthmaticus.

To determine if the Pediatric Asthma Severity Score (PASS) can distinguish "late-rescues" (transfer to the pediatric intensive care unit [PICU] within 24-hours of general pediatric floor admission), "PICU readmissions" (readmission within 24-h after transfer to a lower inpatient level of care), and unplanned 30-day hospital readmission in children admitted with status asthmaticus. We performed a single center, retrospective cohort study in 328 children admitted for asthma exacerbation aged 5-18 years from May 2015 to October 2017. We sought to determine if PASS values preceding admission from the emergency department or transfer to the general pediatric unit will be greater in children with late rescues and PICU readmissions and if a cutoff PASS values exist to discriminate these events prior to intrafacility transfer.

Percutaneous Endoscopic Gastrostomy After Cardiothoracic Surgery in Children Less Than 2 Months Old: An Assessment of Long-Term Malnutrition Status and Gastrostomy Outcomes.

Objectives: Infants with critical congenital heart disease undergoing cardiothoracic surgery commonly experience chronic malnutrition and growth failure. We sought to determine whether placement of a percutaneous endoscopic gastrostomy was associated with reduced moderate-severe malnutrition status and to describe percutaneous endoscopic gastrostomy-related clinical and safety outcomes in this population.

Design: Single-center, retrospective cohort study.

Comparison of Tolerance and Complication Rates Between Early and Delayed Feeding After Percutaneous Endoscopic Gastrostomy Placement in Children.

Background: Enteral nutrition is commonly initiated 24 hours after percutaneous endoscopic gastrostomy (PEG) in children. Adult studies report safe refeeding within 1 to 6 hours of PEG, and these findings have been cautiously applied to children. Comparative studies assessing early versus next-day refeeding in children are currently lacking.

Same-Day versus Overnight Observation after Outpatient Pediatric Percutaneous Liver Biopsy: A Retrospective Cohort Study.

Purpose: Percutaneous liver biopsy (PLB), a diagnostic procedure to identify several hepatobiliary disorders, is considered safe with low incidence of associated complications. While postoperative monitoring guidelines are suggested for adults, selection of procedural recovery time for children remains at the discretion of individual operators. We aim to determine if differences exist in frequency of surgical complications, unplanned admissions, and healthcare cost for children undergoing outpatient PLB for cohorts with same-day vs.

Stress ulcer prophylaxis in children with status asthmaticus receiving systemic corticosteroids: a descriptive study assessing frequency of clinically important bleeding.

To determine the frequency of clinically important bleeding (CIB) among children hospitalized for status asthmaticus with and without exposure to stress ulcer prophylaxis (SUP). We performed a single-center, retrospective cohort in 217 children admitted for asthma exacerbation aged 5-18 years from May 2015 to May 2017. We assessed cohorts with and without exposure to SUP to determine if differences in frequency of CIB exist.

Plays Oncogenic Roles and Is a Therapeutic Target for Wild-Type Melanomas.

Melanoma is one of the most highly mutated cancer types. To identify functional drivers of melanoma, we searched for cross-species conserved mutations utilizing a mouse melanoma model driven by loss of PTEN and CDKN2A, and identified mutations in , and . encodes the SHP2 protein tyrosine phosphatase that activates the RAS/RAF/MAPK pathway.
