Objective: Acute agitation in pediatrics is commonly encountered in hospital settings, can contribute to significant physical and psychological distress, and management is highly varied in practice. As such, the development of a standardized pharmacologic guideline is paramount. We aimed to develop a novel clinical pathway (CP) for management of acute agitation for all hospitalized pediatric patients in Canada., Methods: Healthcare professionals in Canada with expertise in treating and managing pediatric agitation formed a working group and developed a CP through conducting a literature review, engaging key partners, and obtaining interdisciplinary consensus (iterative real-time discussions with content experts). Once developed, the preliminary CP was presented to additional internal and external partners via multiple grand rounds and a webinar; feedback from participants guided final CP revisions., Results: The working group created a pediatric inpatient CP to guide pharmacologic management of agitation and serve as an easy-to-use clinical and educational resource with three complementary sections including: 1) a treatment algorithm, 2) a quick reference medication chart, and 3) two supporting documents, which provide a general overview of non-pharmacologic strategies prior to CP implementation and an illustrative scenario to accompany the medication chart to ensure effective utilization., Conclusions: This is the first CP to standardize pharmacological treatment and management of acute agitation in children in inpatient settings in Canada. Although further research is warranted to assess implementation and support process improvement, the CP can be adapted by individual institutions to assist in prompt pharmacological management of pediatric agitation to potentially improve outcomes for patients, families, and healthcare professionals., Competing Interests: Conflict of Interest: DE is part of the Pharmacogenetic-Guided Antidepressant Prescribing (PGx-GAP) in Adolescents Data Safety Monitoring Board; KS is an unpaid BC representative of the Canadian Academy of Child and Adolescent Psychiatry (CACAP).

We evaluated the usefulness of double immunohistochemical staining for cytokeratin (CK)5/6 and alpha-methylacyl coenzyme A racemase (AMACR) applied sequentially on 1 slide by assessing 223 foci in 110 consecutive prostate specimens. Double-chromogen reaction was used to visualize the antibodies: brown for CK5/6 and red for AMACR. Staining was scored as diffuse, focal, or negative. To establish the diagnosis, CK5/6 and AMACR were correlated with the morphologic features. All cancers lacked CK5/6 staining (100% specificity). AMACR showed diffuse or focal positivity in cancer, high-grade prostatic intraepithelial neoplasia, and atypia in 96.8% (120/124), 85% (22/26), and 80% (16/20) of cases, respectively. In atypical cases, diagnosis was because of non-immunohistochemical staining reasons in 80% of cases. In adenosis (n = 14), AMACR was diffusely positive in 4 cases (29%). Double immunohistochemical staining for CK5/6 and AMACR is a simple assay to perform and may be used as an alternative to antibody cocktails for routine evaluation of problematic prostate specimens.
