Insights

Risk factors for infant plagiocephaly, such as being a multiple birth or having an older mother, increased after 1992. These findings suggest supine sleeping recommendations may influence plagiocephaly development.

Area of Science:

  • Pediatric Health
  • Craniofacial Development
  • Public Health Recommendations

Background:

  • Deformational plagiocephaly is a common condition in infants.
  • The American Academy of Pediatrics (AAP) issued sleep-position recommendations in 1992.
  • Understanding trends in plagiocephaly risk factors is crucial for public health.

Purpose of the Study:

  • To characterize infant and maternal factors associated with plagiocephaly.
  • To analyze temporal changes in potential plagiocephaly risk factors post-1992.

Main Methods:

  • A case-only study design was employed.
  • Infants diagnosed with plagiocephaly or brachycephaly between 1987-2002 were included (n=2733).
  • Characteristics were compared between infants born before (1987-1990) and after (1991-2002) the AAP recommendations.

Main Results:

  • Infants born 1991-2002 showed increased odds of being from multiple births (OR 3.4) and having mothers aged 35+ (OR 3.2).
  • These infants had decreased odds of prolonged birth hospitalization (OR 0.02).
  • Occipital flattening was present in 91.6% and brachycephaly in 17.2% of infants born 1991-2002.

Conclusions:

  • Risk factors for plagiocephaly became more prevalent after the 1992 AAP sleep-position recommendations.
  • Findings support the hypothesis that supine sleeping influences the relationship between risk factors and plagiocephaly.
  • Further controlled studies are recommended for validation.

Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Plastic Deformations01:19

Plastic 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...
Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
Neurulation01:30

Neurulation

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...
