Data addressing safety concerns related to potential drug interactions between cannabis-derived products and pharmaceutical medications in the pediatric population are lacking. In this study, we retrieved case reports through a published literature search using PubMed and spontaneous reporting data using the Food and Drug Administration's Adverse Event Reporting System (FAERS) to identify potential cannabis- and cannabinoid-drug interactions in individuals younger than 18 years old. To evaluate the published case reports, we used the Drug Interaction Probability Scale (DIPS), a 10-item questionnaire designed to discern the causal relationship between a potential drug interaction and adverse drug reactions (ADRs).

Intramedullary nail fixation of unstable tibial diaphyseal fractures is commonly used with excellent clinical results. Indications for nailing have rapidly expanded over recent years, allowing for more difficult fractures to be addressed with "extreme nailing." Despite its widespread use, evolution of newer nailing systems and varying techniques for insertion bring new difficulties with tibial fracture reduction, and malalignment occurs with relative frequency.

Background And Objectives: Isolated REM sleep behavior disorder (iRBD) carries increased risk of neurodegenerative parkinsonian disorder or dementia (NPD) but is difficult to accurately screen for in the community. Health care data offer the opportunity to identify large numbers of iRBD cases among outpatients. We aimed to determine the positive predictive value (PPV) of an RBD (ICD) code for actual iRBD based on manual review of the electronic health record (EHR), examine risk of NPD diagnosis, and explore whether a statistical model developed using selected EHR data can identify individuals with the RBD ICD code who have high probability for actual iRBD.

Background: Acute respiratory illness (ARI) is one of the most common reasons children receive antibiotic treatment. Measurement of C-reaction protein (CRP) has been shown to reduce unnecessary antibiotic use among children with ARI in a range of clinical settings. In many resource-constrained contexts, patients seek care outside the formal health sector, often from lay community health workers (CHW).

Lyme disease, caused by infection with Borrelia burgdorferi, is the most common vector-borne disease in the United States. The standard two-tier testing (STTT) algorithm suffers from low sensitivity, misinterpretation, and long turnaround time, preventing timely detection and treatment. To address these challenges, we hypothesized that the canine point-of-care (PoC) SNAP 4Dx Plus test used to detect Borrelia burgdorferi antibodies could be employed for human diagnosis.
