Summary
Environmental factors, particularly sleep position, significantly influence the lateralization of deformational plagiocephaly (DP). This finding offers guidance for clinical treatment of DP in infants.
Area of Science:
- Pediatrics
- Developmental Biology
- Clinical Research
Background:
- Deformational plagiocephaly (DP) is a common condition in infants.
- The etiology of DP, including factors influencing its lateralization, is not fully understood.
- Previous research has suggested both biological and environmental influences on DP lateralization.
Purpose of the Study:
- To statistically evaluate the independent and interacting effects of biological and environmental risk factors on DP lateralization.
- To provide evidence-based guidance for the clinical management of DP.
- To identify key predictors of lateralization in deformational plagiocephaly.
Main Methods:
- Analysis of a large database (>20,000 children) treated for DP.
- Utilized 2- and 3-way factor analyses for categorical frequency data.
- Collected data on parity, zygosity, intrauterine presentation, birth details, sleep position, lateralization, and sex.
Main Results:
- Male infants were overrepresented in the DP cohort.
- DP lateralization was significantly correlated with primiparity, specific intrauterine presentations (breech, transverse), and dizygotic twinning.
- Infant sleep position emerged as the strongest predictor of lateralization, independent of biological factors.
Conclusions:
- Environmental factors, especially infant sleep position, play a predominant role in DP lateralization.
- Findings challenge the sole reliance on biological explanations for DP lateralization.
- Sleep position is a critical modifiable factor for clinical intervention in DP.

01:19Plastic Deformations
Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their original...
01:14Plastic Deformations
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...
01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:09Cytoskeletal Linker Proteins - Plakins
Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
