Utility of Urine Dipstick Testing in Pediatric Appendicitis: Assessing its Role in Identifying Complicated Cases and Retrocecal Appendicitis.

Background:  Diagnosing appendicitis in children remains a challenge, and the role of urine dipstick is controversial. This study aimed to evaluate the association between abnormal urine dipstick results and appendicitis, particularly appendicitis severity and appendix position.

Methods:  A prospective cohort study was conducted from 2017 to 2021 at a tertiary hospital in Sweden.

Associations between Th1-related cytokines and complicated pediatric appendicitis.

The pathogenesis of appendicitis is not understood fully, and the diagnosis can be challenging. Previous research has suggested an association between a T helper (Th) 1-dependent immune response and complicated appendicitis. This prospective cohort study aimed to evaluate the association between serum concentrations of the Th1-associated cytokines interleukin (IL)-1α, IL-1β, IL-2, IL-6, IL-10, IL-17A and tumor necrosis factor beta (TNF-β) and the risk of complicated appendicitis in children.

CT doses based on clinical indications. New national DRL's in Iceland.

A diagnostic reference level (DRL) is an investigation level to use in the optimization of a medical exposure using ionizing radiation. The aim of this project was to gather dose data from computed tomography (CT) studies in Iceland with the purpose of updating existing national DRL and proposing DRLs based on clinical indications. Dose data (total dose length product (DLP) and CT dose index) were retrospectively collected from all CT scanners in Iceland for 50 patients for all common CT studies.

An Evaluation of Serum IgE and Th2-Associated Interleukins in Children With Uncomplicated and Complicated Appendicitis.

Background: The pathogenesis of appendicitis is not understood completely and establishing a correct diagnosis can be clinically challenging. Previous investigations have shown an association between a T helper cell (Th)2-mediated inflammatory response, for example immunoglobulin E (IgE)-mediated allergy, and a decreased risk of complicated appendicitis. The present study aimed to evaluate differences in serum concentrations of IgE and Th2-associated interleukins (IL) in children with uncomplicated and complicated appendicitis.
