Insights

Ventriculo-peritoneal shunts (VPS) in infants under 3 months showed similar 1-year failure and infection rates compared to older children. Improved care and antibiotic catheters may explain these findings.

Area of Science:

  • Pediatric Neurosurgery
  • Medical Device Outcomes
  • Hydrocephalus Management

Background:

  • Ventriculo-peritoneal shunts (VPS) are the primary treatment for pediatric hydrocephalus.
  • Neonates are generally believed to have higher VPS failure and infection rates than older children.
  • This study investigates if this perceived higher risk is accurate in current practice.

Purpose of the Study:

  • To compare the 1-year shunt failure and infection rates of VPS insertion in children under 3 months old versus older children.
  • To evaluate the outcomes of VPS in neonates and young infants.
  • To identify factors influencing shunt outcomes in this population.

Main Methods:

  • Retrospective review of 58 children under 3 months who underwent VPS insertion between January 2007 and December 2016.
  • Comparison of 1-year failure and infection rates with historical data for children over 3 months.
  • Analysis of institutional data for shunt-related complications.

Main Results:

  • Children under 3 months had a 29.3% 1-year shunt failure rate (17/58).
  • The 1-year shunt infection rate in this group was 3.4% (2/58).
  • These rates were comparable to the 26.1% failure and 4.3% infection rates observed in children over 3 months.

Conclusions:

  • Infants under 3 months undergoing VPS insertion do not necessarily have worse 1-year outcomes than older children.
  • Potential contributing factors include increased subspecialization, antibiotic-impregnated catheters, and improved neonatal care.
  • These findings challenge the assumption of higher risk in younger infants for VPS procedures.

Shunt Admittances

Shunt admittances play a crucial role in the analysis of transmission lines, particularly for three-phase systems with neutral conductors. When a uniformly charged conductor is positioned above the Earth, it induces an equal but opposite charge on its surface. This interaction creates electric field lines between the conductor and the Earth.
To model this effect, the method of images is employed. This method involves replacing the Earth with an image conductor that mirrors the original...

Reaction Rate02:53

Reaction Rate

The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...

When two or more physical quantities are linked by a single relationship, a change in one variable necessarily affects the others. This interdependence forms the basis of related rates analysis, which examines how different quantities change with respect to time. A classic physical example is an expanding balloon, where the size of the balloon changes continuously as air is added.For a hot air balloon, the inflated envelope is commonly idealized as a perfect sphere to simplify mathematical...

Temperature Dependence on Reaction Rate

The Collision Theory
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...
