Sex cord tumors with annular tubules are known to originate from the sex cord of embryonic gonads that synthesize Sertoli cells, Leydig cells, granulosa cells, and theca cells of the ovarian stroma, while ovarian small cell carcinoma of the hypercalcemic type is a type of neuroendocrine tumor. Both these tumors are uncommon, potentially malignant neoplasms in children. We report the case of a sex cord tumor with annular tubules in an 11-year-old girl and a case of small cell carcinoma of the hypercalcemic type in a 10-year-old girl. We also discuss the prognosis and management of these tumors.

Loss of cervical lordosis (LOCL) is the most common postoperative cervical deformity. This study aimed to identify the predictors of LOCL by investigating the relationship between various factors and LOCL development after surgery for cervical spinal cord tumors. A retrospective analysis was conducted on 51 patients who underwent cervical spinal tumor resection at a single center.

Unlabelled: Introduction-Aim: Validated triage tools such as the Vittel criteria are essential to improve the care of trauma patients. The aim of this study was to evaluate the correlation between the Vittel triage criteria and the Injury Severity Score (ISS) to improve the accuracy of pre-hospital triage.
Methods: We conducted a longitudinal study of all trauma patients transported by EMS over a two-year period (November 2021- November 2023).

Low iron stores at birth may adversely influence child cognitive and motor development. The aims of this study were to assess cord blood iron levels and explore maternal and neonatal factors associated with iron status. Cord blood specimens (=46) were obtained from the BC Children's Hospital BioBank in Vancouver, Canada.

Introduction: Longitudinally extensive spinal cord lesions (LESCL) are characterized by T2-hyperintense signals spanning at least three vertebral body segments, with neuromyelitis optica spectrum disorders (NMOSD) being a significant cause. This study aimed to characterize the clinical, radiological, serological, and cerebrospinal fluid (CSF) features of LESCL and to compare NMOSD and non-NMOSD cases.
Methods: We conducted a retrospective cross-sectional study of adult patients diagnosed with LESCL at our center over a twelve-year period collecting data on demographics, clinical presentations, MRI findings, CSF analysis, and serological testing for AQP4-IgG and MOG-IgG antibodies.
