Evaluation of the Use of Ketamine in Prehospital Seizure Management: A Retrospective Review of the ESO Database.

Objectives: Benzodiazepines are the primary antiseizure medication used by Emergency Medical Services (EMS) for seizures. Available literature in the United States and internationally shows 30% to 40% of seizures do not terminate with benzodiazepines called benzodiazepine refractory status epilepticus (BRSE). Ketamine is a potential treatment for BRSE due to its unique pharmacology.

The Success of Resident-Associated Lumbar Punctures at a Large, Single-Center Children's Hospital.

Objectives: The frequency of lumbar punctures (LPs) has declined across US children's hospitals over the past decade, potentially decreasing procedural learning opportunities for pediatric resident trainees. Our study sought to determine whether the proportion of successful LPs performed by our pediatric residents has significantly changed over time.

Methods: This study is a single-center retrospective study to evaluate our pediatric resident LP success.

Aligning Provider Prescribing With Guidelines for Soft Tissue Infections.

Objective: Despite evidence-based guidelines, antibiotics prescribed for uncomplicated skin and soft tissue infections can involve inappropriate microbial coverage. Our aim was to evaluate the appropriateness of antibiotic prescribing practices for mild nonpurulent cellulitis in a pediatric tertiary academic medical center over a 1-year period.

Methods: Eligible patients treated in the emergency department or urgent care settings for mild nonpurulent cellulitis from January 2017 to December 2017 were identified by an International Classification of Diseases, Tenth Revision, code for cellulitis.

Psychiatric Education for Pediatric Emergency Medicine Fellows: Should We be Doing More?

Unlabelled: The number of psychiatric encounters is steadily increasing across all pediatric emergency departments. Based on this growing national crisis, we hypothesized there is a lack of robust education in behavioral/mental health emergencies during pediatric emergency medicine (PEM) fellowship.

Methods: This was a cross-sectional survey of PEM fellowship directors.

Adults Followed by Pediatric Subspecialists: A Growing Population in the Pediatric Emergency Department.

Background: Adults are being seen with increasing frequency in pediatric emergency departments (PEDs), but the drivers behind this increase are unknown. Our primary aim was to compare adults seen in the PED followed by pediatric subspecialists to those who are not.

Methods: A retrospective study of patients 21 years or older presenting to the PED of a tertiary care children's hospital was performed from January 2011 through December 2018.

N-O chemistry for antibiotics: discovery of N-alkyl-N-(pyridin-2-yl)hydroxylamine scaffolds as selective antibacterial agents using nitroso Diels-Alder and ene chemistry.

The discovery, syntheses, and structure-activity relationships (SAR) of a new family of heterocyclic antibacterial compounds based on N-alkyl-N-(pyridin-2-yl)hydroxylamine scaffolds are described. A structurally diverse library of ∼100 heterocyclic molecules generated from Lewis acid-mediated nucleophilic ring-opening reactions with nitroso Diels-Alder cycloadducts and nitroso ene reactions with substituted alkenes was evaluated in whole cell antibacterial assays. Compounds containing the N-alkyl-N-(pyridin-2-yl)hydroxylamine structure demonstrated selective and potent antibacterial activity against the Gram-positive bacterium Micrococcus luteus ATCC 10240 (MIC(90) = 2.

Siglec-9 and SHP-1 are differentially expressed in neonatal and adult neutrophils.

Neonatal PMN (polymorphonuclear neutrophils) exhibit altered inflammatory responsiveness and greater longevity compared with adult PMN; however, the involved mechanisms are incompletely defined. Receptors containing immunoreceptor tyrosine-based inhibitory motif (ITIM) domains promote apoptosis by activating inhibitory phosphatases, such as Src homology domain 2-containing tyrosine phosphatase-1 (SHP-1), that block survival signals. Sialic acid-binding immunoglobulin-like lectin (Siglec)-9, an immune inhibitory receptor with an ITIM domain, has been shown to induce cell death in adult PMN in association with SHP-1.
