Bullying02:04

Bullying

8.8K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Radicals01:27

Radicals

398
Roots, often written as radicals, identify the quantity that must be raised to a specific exponent to produce a given value. A radical expression consists of two main components: the radicand, which is the value placed inside the root symbol, and the index, which indicates the degree of the root being taken. The notation n√a indicates the principal nth root of a. If n equals 2, the operation is the square root, while n = 3 defines the cube root. When n is even, a negative radicand does...

Aggression01:47

Aggression

30.1K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Resistance01:19

Resistance

5.6K
When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

550
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Maximum Deflection01:13

Maximum Deflection

933
When analyzing beams under unsymmetrical loads, such as a train moving on a bridge, it is crucial to accurately determine the points of maximum stress and deflection. The process involves identifying the maximum deflection of the beam, which may not always occur at its midpoint due to the uneven distribution of the load.
The maximum deflection occurs at a specific point, known as point O, where the tangent to the deflection curve is horizontal. To find point O, the slope of the tangent at any...

Area of Science:

  • Pediatric Pulmonology
  • Diagnostic Imaging
  • Thoracic Surgery

Background:

  • Exercise-induced dyspnea and stridor in children can mimic vocal cord dysfunction.
  • Persistent respiratory symptoms necessitate comprehensive diagnostic evaluation.

Observation:

  • A 12-year-old female presented with a 7-month history of exertional dyspnea, stridor, and chest tightness.
  • Initial spirometry suggested obstructive airflow, and later, dysphagia developed.
  • Bronchoscopy identified extrinsic compression of the mid-lower trachea and right main bronchus.

Findings:

  • Extrinsic compression of the trachea and right main bronchus was confirmed.
  • The findings suggest a potential mediastinal mass or vascular anomaly as the cause.

Implications:

  • This case highlights the importance of considering extrinsic airway compression in pediatric patients with persistent respiratory symptoms.
  • Advanced imaging like CT scans are crucial for diagnosing such conditions.
  • Prompt diagnosis and management are essential to prevent severe respiratory compromise.
