Isolated lateralized overgrowth: clinical, radiological, and auxological characteristics of a single-site cohort of 76 cases.

Introduction: Isolated lateralized overgrowth (ILO), formerly referred to as hemihyperplasia/hemihypertrophy, is the overgrowth of one-half of the body to its contralateral in the absence of a recognizable pattern of malformations or genetic syndromes. Our objective was to analyze the growth clinical and radiological characteristics of patients with ILO under follow-up in a tertiary care hospital in Argentina between 1993 and 2020.

Population And Methods: Retrospective, observational, single cohort study of patients with ILO.

Growth in achondroplasia, from birth to adulthood, analysed by the JPA-2 model.

Objectives: In general population, there are three phases in the human growth curve: infancy, childhood and puberty, with different main factors involved in their regulation and mathematical models to fit them. Achondroplasia children experience a fast decreasing growth during infancy and an "adolescent growth spurt"; however, there are no longitudinal studies that cover the analysis of the whole post-natal growth. Here we analyse the whole growth curve from infancy to adulthood applying the JPA-2 mathematical model.

Height growth velocity during infancy and childhood in achondroplasia.

There is a lack of knowledge about longitudinal growth during childhood in achondroplasia. We report patterns of linear growth and height growth velocity references. The sample consisted of 84 children, 41 girls and 43 boys.

Growth velocity and biological variables during puberty in achondroplasia.

Background: Achondroplasia is the most common form of inherited disproportionate short stature. Cross-sectional design studies of height show that, during childhood, height standard deviation scores (SDS) declines steadily and reaches a mean adult height at -6.42 and -6.

Short-term growth in head circumference and its relationship with supine length in healthy infants.

Background: Daily changes in height have been found to be a non-linear process. Its exact pattern is still controversial. In previous studies on 34 healthy children aged 0.

Short-term growth in healthy infants, schoolchildren and adolescent girls.

Background: There is agreement amongst most investigators now on the fact that growth, when measured over short periods, is an irregular and non-linear process. However, many aspects related to this process still remain controversial, for example, the continuity or discontinuity of the daily changes and the degree of existence of age differences in growth patterns.

Aim: In this study we analyse and compare growth in height based on daily measurements in three samples of healthy children: Eight infants (I), 16 schoolchildren (S) and 10 adolescent girls during their pubertal growth spurt (A).
