Summary
A rare bony anomaly of the axis (C2) vertebra caused a swelling in a 10-year-old boy. Surgical removal was successful, highlighting potential cosmetic needs for such spinal abnormalities.
Area of Science:
- Orthopedics
- Radiology
- Pediatric Surgery
Background:
- Axis (C2) vertebral bony anomalies are documented.
- Posterior element expansion of the C2 vertebra is less common.
Observation:
- A 10-year-old male presented with a progressive upper cervical swelling.
- Physical examination revealed a firm, 8x5 cm neck mass.
- Imaging showed an additional bony arch on the C2 spinous process with an internal soft tissue mass.
Findings:
- Computed tomography confirmed an accessory bony arch attached to the C2 spinous process.
- Magnetic resonance imaging demonstrated a soft tissue mass within the bony ring, without neural involvement.
- No focal neurological deficits were present.
Implications:
- Anomalous C2 spinous process expansion can be asymptomatic or present with swelling.
- Surgical excision may be indicated for cosmetic reasons or if symptomatic.
- This case expands the understanding of C2 vertebral anomalies.

01:26EDTA: Auxiliary Complexing Reagents
1.3K
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...

The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

4.6K
The perpendicular-axis theorem states that the moment of inertia of a planar object about an axis perpendicular to its plane is equal to the sum of the moments of inertia about two mutually perpendicular concurrent axes lying in the plane of the body.
Consider a circular disc of mass M and radius R lying along an x-y plane. The origin lies at the center of the disc, and the z-axis is perpendicular to the disc's plane. All three axes coincide at the disc's center. The moment of inertia of this...

8.3K
The parallel-axis theorem provides a convenient and quick method of finding the moment of inertia of an object about an axis parallel to the axis passing through its center of mass. Consider a thin rod as an example. There is a striking similarity between the process of finding the moment of inertia of a thin rod about an axis through its middle, where the center of mass lies, and about an axis through its end using the conventional method. In the conventional method, the concept of linear mass...

In structural engineering, the analysis of beams subjected to varying loads is a critical aspect of understanding the behavior and performance of these structural elements. A common scenario involves a beam subjected to a combination of different load distributions.
Consider a beam of length L subjected to a varying load, which is a combination of parabolic and trapezoidal load distribution along the x-axis. In this case, it is essential to determine the resultant loads, their locations, and...

The moment of inertia is a fundamental concept in mechanical engineering that plays a significant role in designing rotationally symmetric objects such as flywheels, gears, and other mechanical systems. In this context, we will discuss the moment of inertia of a flywheel rotating about its centroidal axis and how it relates to the moment of inertia about an axis parallel to it.
