Characteristics and management of eosinophilic esophagitis in Australasian children: a decade of experience.

Background: The frequency of EoE has been increasing in Northern Hemisphere cohorts, yet there is a scarcity of data in our region. Regional climatic factors, and lifestyle habits may influence the presentation of EoE, and appropriate management is crucial to prevent complications. WIth this is mind we undertook the first comprehensive multisite study of EoE in Australasian children.

The Role of Topical Tacrolimus in the Management of Inflammatory Bowel Disease: A Comprehensive Review.

Management of ulcerative colitis and Crohn's disease, the main subtypes of inflammatory bowel disease (IBD), focuses on the induction and maintenance of remission. Tacrolimus, a member of a group of drugs termed calcineurin inhibitors, may have a role in the medical management of IBD when given either systemically or topically. This review aimed to evaluate the available data focusing on the use of topical tacrolimus in the management of IBD.

Qualitative and quantitative determination of xylazine in oral fluid.

Xylazine has emerged in recent years as a dangerous adulterant in illicit fentanyl use, and methods for the detection of xylazine in toxicology panels are still lagging. We developed methods for the screening and quantitation of xylazine in oral fluid (OF), a popular testing medium due to its ease of collection and reflection of presence in blood for many classes of drugs. Enzyme-linked immunosorbent assays were employed for the rapid screening of xylazine directly from the collection device buffer with a cutoff of 1 ng/mL.

Evolution of a Pathogenic Microbiome.

The process of microbiome development arguably begins before birth. Vertical transmission of bacteria from the mother to the infant is a keystone event in microbiome development. Subsequent to birth, the developing microbiome is vulnerable to influence from a wide range of factors.
