Discussions regarding bone density typically focus on postmenopausal women, osteoporosis, and fracture risk. Although these are the most common reasons patients have skeletal strength assessments, the use of bone densitometry and bone mineral density measurement in pediatric patients is becoming increasingly valuable to assess children with diseases that cause inadequate bone growth. This article discusses pediatric bone disease and current and emerging imaging options for assessing bone density in children and adolescents.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Background: Previous studies have reported normative data for sagittal spinal alignment in asymptomatic adults. The sagittal spinal alignment change in European children was recently reported. However, there is a lack of studies on the normative reference values of sagittal spinal and pelvic alignment and how these parameters change at different growth stages in Chinese children.

Purpose: This meta-analytical systematic review aims at investigating the variability of the pterion, focusing on its morphological types and precise distances from various bony landmarks. Additionally, the neurosurgical significance of this critical cranial landmark is examined in depth.
Methods: The systematic review was conducted following PRISMA 2020 and Evidence-based Anatomy Workgroup guidelines for anatomical studies.

The immune responses following SARS-CoV-2 infection in children are still under investigation. While coronavirus disease 2019 (COVID-19) is usually mild in the paediatric population, some children develop severe clinical manifestations or multisystem inflammatory syndrome in children (MIS-C) after infection. MIS-C, typically emerging 2-6 weeks after SARS-CoV-2 exposure, is characterized by a hyperinflammatory response affecting multiple organs.

Hypophosphatasia (HPP) is an inherited error in metabolism resulting from loss-of-function variants in the gene, which encodes tissue-nonspecific alkaline phosphatase (TNAP). TNAP plays a crucial role in biomineralization of bones and teeth, in part by reducing levels of inorganic pyrophosphate (PP), an inhibitor of biomineralization. HPP onset in childhood contributes to rickets, including growth plate defects and impaired growth.
