Article Abstract
Objectives: Understanding the characteristics of the pubertal growth spurt in Korean children and adolescents can serve as crucial foundational data for researching puberty and growth-related disorders. This study aims to estimate the key parameters of pubertal growth, specifically the age and magnitude of the pubertal growth spurt, utilizing longitudinal data from a cohort of Korean children and adolescents.
Methods: This study used mixed longitudinal height data from a cohort of Korean elementary, middle, and high school students aged 7-18 years. The Superimposition by Translation and Rotation (SITAR) model, a shape-invariant growth curve model, was utilized to estimate a reference height velocity curve for the entire dataset and individual curves via random effects to evaluate pubertal growth parameters. Altogether, 3,339 height measurements (1,519 for boys and 1,820 for girls) from 270 individuals (123 boys and 147 girls) were analyzed.
Results: The average age of growth spurt onset in Korean boys was 10.17 ± 0.61 years (mean ± SE), with peak height velocity occurring at 12.46 ± 0.69 years of age (9.61 ± 1.26 cm/year). Korean girls, contrarily, experience their growth spurt at an earlier age (8.57 ± 0.68 years), with peak height velocity occurring at 10.99 ± 0.74 years of age (8.32 ± 1.09 cm/year). An earlier onset of puberty in both sexes is associated with a shorter growth spurt duration (0.63 years for boys and 0.58 years for girls) and a higher peak height velocity (1.82 cm/year for boys and 1.39 cm/year for girls). These associations were statistically significant for both sexes (all < 0.0001).
Conclusion: This study is the first to use the height velocity curve from the SITAR model to examine the pubertal growth spurt of Korean children and adolescents. The estimated timing and magnitude of the pubertal growth spurt, and their relationships can be useful data for clinicians and researchers.

The Utility of Cervical Vertebral Maturation Method for Staging Skeletal Growth and Curve Progression in Patients with Adolescent Idiopathic Scoliosis.

Background: Cervical vertebral maturation (CVM) is a skeletal maturity method that can be assessed routinely on whole spine radiographs to minimize radiation exposure. Originally used in orthodontics, its role in staging adolescent growth spurt and curve progression in adolescent idiopathic scoliosis (AIS) remains unclear. The aim of this study was to investigate growth rates across CVM stages, its cutoff for indicating peak growth (PG) versus growth cessation (GC), and its relationship with coronal curve progression.

It typically presents as asymptomatic, atrophic, or hyperpigmented linear bands, most commonly on the back. We report a case of LFE in a 15-year-old healthy male who presented with multiple asymptomatic, parallel hypopigmented linear bands with hyperpigmented borders on his back.

Objective: This study aimed to describe inter-individual variation in growth velocity during puberty among Brazilian children, considering maturity status to better understand differences in the timing and intensity of growth spurts.
Methods: Longitudinal stature data from 398 Brazilian children (197 girls, 201 boys) aged 6-19 years, collected annually from 1997 to 2010, were analyzed. Growth and velocity curves were estimated using the SITAR model within a Bayesian framework.

Linear focal elastosis (LFE), characterised by horizontal streaks on the lower back, is a dermatological condition with unclear etiopathogenesis and limited epidemiological data. This study synthesises case reports to elucidate demographic patterns, clinical manifestations, and potential associations. A literature search across PubMed, Embase, Ovid and ResearchGate identified 37 relevant articles, yielding 80 cases after excluding duplicates and irrelevant articles.

Objective: Numerous child growth studies showed the adolescent growth spurt in body height to the extent that its presence became a dogma applied to humans as a species. However, observations of growth in the 19th c. and in small traditional societies showed for some children a steady growth without visible pubertal spurt.
