Summary
Lambdoid positional molding (LPM) in infants is increasingly common due to sleep positioning and carrier use. Associated neurological and systemic issues, not craniosynostosis, require attention.
Area of Science:
- Pediatric Neurology
- Developmental Pediatrics
- Craniofacial Abnormalities
Background:
- Lambdoid positional molding (LPM) is a common condition in infants.
- Current infant care practices may contribute to its increased incidence.
Observation:
- A study reviewed 121 infants with LPM, noting clinical features like occipital flattening, alopecia, and ear displacement.
- Associated findings included head tilt, torticollis, large head circumference, and excess cerebrospinal fluid.
- A significant male and right-sided preponderance was observed.
Findings:
- LPM was frequently associated with torticollis, large head circumference, excess cerebrospinal fluid, and developmental delays.
- Craniosynostosis was rare, with only 3 cases identified.
- No evidence suggested LPM causes compressive brain pathology.
Implications:
- The study suggests current infant positioning recommendations and carrier use contribute to LPM.
- Underlying central nervous system (CNS) and systemic issues associated with LPM require management.
- Surgical intervention for LPM is generally not indicated, as it does not address underlying pathologies and may be misinterpreted.

01:20Plastic Deformation in Circular Shafts
When materials are subjected to forces that surpass their yield strength, they undergo a process known as plastic deformation. This results in a permanent alteration or strain in their structure. This concept can be specifically applied to circular shafts, where the deformation leads to a change in its shape. The precise evaluation of this plastic deformation requires understanding the stress distribution within the circular shaft, which is achieved by calculating the maximum shearing stress in...
01:07Symmetric Member in Bending
In the study of the mechanics of materials, analyzing the behavior of prismatic members under opposing couples is crucial for understanding internal stress distributions, which are essential for structural design. When subjected to couples, a prismatic member experiences internal forces that maintain equilibrium. A couple, characterized by two equal and opposite forces, creates a moment but no resultant force. The internal forces at any section cut of the member must balance these external...
01:18Deformations in a Symmetric Member in Bending
When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.

01:21Plastic Deformations of Members with a Single Plane of Symmetry
When a structural member undergoes plastic deformation due to bending, it is crucial to understand the position of the neutral axis and the stress distribution. This member, characterized by a single plane of symmetry, exhibits a uniform stress distribution, with negative stress above the neutral axis and positive stress below. Notably, the neutral axis does not align with the centroid of the cross-section. This misalignment is typical in cases where the cross-section is not rectangular or...
01:18Unsymmetric Bending
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from those in symmetrical bending, and are essential for designing structures to withstand different loading conditions. In unsymmetrical bending, the neutral axis—where stress is zero—does not necessarily align with the geometric axes of the cross-section. The orientation of the...
01:15Unsymmetric Bending - Angle of Neutral Axis
Unsymmetrical bending occurs when a structural member is subjected to bending moments in a plane that does not align with the member's principal axes. This scenario typically arises in beams and other structural components when loads are applied at non-ideal angles, introducing complexities in stress analysis.
When a bending moment is applied at an angle θ concerning the vertical axis of a symmetrical member, it can be resolved into components along the member's principal centroidal axes. The...
