Background: The need for chest X-rays (CXR) following large-bore chest tube removal has been questioned; however, the utility of CXRs following removal of small-bore pigtail chest tubes is unknown. We hypothesized that CXRs obtained following removal of pigtail chest tubes would not change management.
Methods: Patients < 18 years old with pigtail chest tubes placed 2014-2019 at a tertiary children's hospital were reviewed.
Background: There is little information on the effects of Pseudomonas infection on outcomes in perforated appendicitis. As Pseudomonas is not covered by many empiric appendicitis antibiotic regiments, we hypothesized that children with Pseudomonas would have worse outcomes.
Methods: Patients <18 years old undergoing appendectomy for perforated appendicitis at a tertiary children's hospital 2015-2019 were included and were stratified by presence of Pseudomonas on intraoperative culture.
Q fever is a worldwide zoonosis caused by that can lead to abortion, endocarditis, and death in humans. Researchers utilizing parturient domestic ruminants, including sheep, have an increased risk of occupational exposure. This study evaluated the effectiveness of our screening protocol in eliminating -positive sheep from our facility.

Methods: PMSC lines were created following explant culture of three early-gestation human placentas. In vitro neuroprotection was assessed with a neuronal apoptosis model.
