Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
Pharmacokinetics in Pediatric Patients: Drug Distribution01:17

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
Fluid Pressure01:14

Fluid Pressure

In mechanical engineering, fluid pressure plays a critical role in designing systems that utilize liquid flow, such as hydraulic systems, pumps, and valves. When designing these systems, engineers must ensure they can withstand the forces created by fluid pressure to avoid damage or failure.
According to Pascal's law, a fluid at rest will generate equal pressure in all directions. This pressure is measured as a force per unit area, and its magnitude depends on the fluid's specific weight or...
Pressure Relationships in Thoracic Cavity01:24

Pressure Relationships in Thoracic Cavity

Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...
Pressure Variation in a Fluid at Rest01:11

Pressure Variation in a Fluid at Rest

In a fluid at rest, the pressure at any point beneath the fluid surface depends solely on the depth, not on the container's shape or size. This principle, known as hydrostatic pressure, arises because, in stationary fluids, there is no acceleration, meaning the forces within the fluid balance out. Only vertical forces, caused by the weight of the fluid above, contribute to pressure changes with depth.
When measuring pressure at two different levels within the fluid, the difference in pressure...
Fluid Pressure over Flat Plate of Variable Width01:02

Fluid Pressure over Flat Plate of Variable Width

When a flat plate is submerged in a fluid, the fluid exerts pressure on the plate. This pressure can lead to many different phenomena, including drag and buoyancy. To understand the behavior of the fluid over a flat plate of variable width, it is essential to analyze the distribution of the pressure exerted.
The pressure distribution on the plate can be calculated by determining the force that acts on a differential area strip of the plate. Thus, the magnitude of the force is equal to the...

Area of Science:

  • Biomechanics
  • Pediatric Podiatry
  • Gait Analysis

Background:

  • Traditional plantar pressure measurement methods lack consideration for orthotics and footwear interactions.
  • The Pedar pressure insole system offers a more comprehensive approach to gait analysis.

Purpose of the Study:

  • To establish normative plantar pressure parameter data during the stance phase of gait in children.
  • To utilize the Pedar pressure insole system for accurate data collection.

Main Methods:

  • Twenty-nine healthy children (6-16 years) participated, walking at self-selected speeds.
  • Participants were categorized into 'juniors' (<12 years) and 'teenagers' (>13 years) for analysis.
  • Plantar pressure data was collected using the Pedar system, analyzing 7 parameters across 8 anatomical regions.

Main Results:

  • No statistically significant differences in plantar pressure parameters were observed between the junior and teenager groups.
  • Analysis showed no significant differences based on sex or between left and right feet for the measured parameters.

Conclusions:

  • The generated normative data serves as a benchmark for assessing pediatric foot deformities.
  • This data aids in differentiating dynamic foot deformities from anatomical ones.
  • Level II evidence supports the findings.
