The 4-aminoquinazoline scaffold is a privileged structure in medicinal chemistry. Regioselective nucleophilic aromatic substitution (SAr) for replacing the chlorine atom at the 4-position of 2,4-dichloroquinazoline precursors is well documented in the scientific literature and has proven useful in synthesizing 2-chloro-4-aminoquinazolines and/or 2,4-diaminoquinazolines for various therapeutic applications. While numerous reports describe reaction conditions involving different nucleophiles, solvents, temperatures, and reaction times, discussions on the regioselectivity of the SAr step remain scarce.

Study Design: Cohort retrospective study.

Objective: We evaluated and compared the outcomes of anterior cervical discectomy with fusion (CDF) and anterior cervical corpectomy with iliac crest graft and fusion (CCF) in patients with ≥3 level degenerative cervical myelopathy (DCM).

Background: Anterior and posterior approaches are widely employed in DCM when compressive elements predominate in the anterior or posterior spinal cord, respectively.

Foreign body (FB) ingestion and aspiration are frequent causes of pediatric emergency room visits, with significant morbidity and mortality risks. This cross-sectional study analyzed 1,052 pediatric patients admitted for suspected FB events at a single institution between 2008 and 2015, including 886 cases of suspected ingestion and 166 cases of suspected aspiration. Cluster analysis identified three distinct clusters for both groups, with respiratory symptoms being predominant in clusters with worse outcomes.
