Article Abstract
Aim: To measure and compare computed tomography (CT) radiation doses delivered to patients in public paediatric hospitals in Australia and Saudi Arabia.
Methods: Doses were measured for routine CT scans of the head, chest and abdomen/pelvis for children aged 3-6 years in all dedicated public paediatric hospitals in Australia and Saudi Arabia using a CT phantom measurement cylinder.
Results: CT doses, using the departments' protocols for 3-6 year old, varied considerably between hospitals. Measured head doses varied from 137.6 to 528.0 mGy(·)cm, chest doses from 21.9 to 92.5 mGy(·)cm, and abdomen/pelvis doses from 24.9 to 118.0 mGy(·)cm. Mean head and abdomen/pelvis doses delivered in Saudi Arabian paediatric CT departments were significantly higher than those in their Australian equivalents.
Conclusion: CT dose varies substantially across Australian and Saudi Arabian paediatric hospitals. Therefore, diagnostic reference levels should be established for major anatomical regions to standardise dose.

Objective: Epidemiological data on rare spinal cord malformations in children are lacking in France. Using the national hospital discharge database (PMSI), we studied the care trajectories and estimated the morbidity and mortality burden of these conditions.
Study Design: We conducted a nationwide historical cohort study from 2010 to 2020, including children diagnosed with rare spinal cord diseases within the scope of the C-MAVEM network.

Objectives: To assess patterns across 21 countries in dentists' thresholds for initiating operative treatment of active non-cavitated carious lesions and to evaluate the influence of caries risk, clinician characteristics, and geographic variation on decision-making in accordance with current guidelines.
Methods: A cross-sectional, vignette-style web-based survey was conducted between June and October 2023 across 21 countries. A standardized questionnaire, comprising theoretical radiographic scenarios of occlusal and approximal active non-cavitated carious lesions at four progressive stages (E1,E2,EDJ,D1), was distributed to general dentists and specialists.
Rapid Diagnosis and Subtyping of Hermansky-Pudlak Syndrome With Flow Cytometry Analysis.
Pigment Cell Melanoma Res

Department of Dermatology, Beijing Tongren Hospital, Capital Medical University, Beijing, China.
The diagnostic approaches for Hermansky-Pudlak Syndrome (HPS) include genetic sequencing, immunoblotting, electron microscopy (EM), and flow cytometry with mepacrine staining. However, these methods are often impractical for routine clinical use due to high cost, technical complexity, and limited availability. In this study, we evaluated dense granules (DGs) function in HPS mouse models using flow cytometry with mepacrine and FluoZin-3 staining.

Background: Although prior studies have estimated the burden of pediatric surgical disease in low- and middle-income countries (LMICs) through statistical modeling and hospital- or household-based surveys, few large-scale descriptions of procedures and outcomes have been published. We aimed to describe the epidemiology and outcomes of children's surgical care at multiple centers across Africa.
Methods: Perioperative clinical data were collected prospectively from 2018 to 2023 at 17 hospitals in 11 African countries using a preexisting tool.

Unlabelled: Benign Acute Childhood Myositis (BACM) is a transient, self-limiting muscular condition that typically follows viral infections, especially influenza. The COVID-19 pandemic disrupted the circulation of respiratory viruses, altering the epidemiology of related post-infectious complications. This study investigates trends in BACM incidence, clinical features, and viral etiology before and after the pandemic.
