Children

Area of Science:

  • Pediatric Neurosurgery
  • Neurology
  • Medical Imaging

Background:

  • Stereotactic electroencephalogram (SEEG) is an invasive diagnostic procedure.
  • Accurate electrode placement and fixation are crucial for SEEG efficacy.
  • Understanding pediatric cranial bone thickness is vital for surgical planning.

Purpose of the Study:

  • To measure cranial bone thickness in children during SEEG procedures.
  • To assess the impact of bone thickness on electrode fixation.
  • To evaluate the safety and reliability of robot-assisted SEEG in pediatric epilepsy.

Main Methods:

  • Retrospective analysis of 13 children undergoing robot-assisted SEEG (ROSA).
  • Measurement of skull thickness at electrode sites using post-operative CT scans.
  • Recording of electrode screw loosening and adverse events.

Main Results:

  • Significant variations in cranial bone thickness were observed across different skull regions (P<0.01).
  • Temporal bone was the thinnest (3.5±1.3 mm), while occipital bone was the thickest (6.9±0.5 mm).
  • Minor screw loosening occurred in 4 electrodes (3.5%), primarily in the temporal bone, without affecting SEEG recordings or causing adverse events.

Conclusions:

  • Pediatric cranial bone is thinner than adult bone.
  • Robot-assisted SEEG is a safe and reliable procedure for children with epilepsy.
  • The observed screw loosening did not compromise SEEG data quality or patient safety.

Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Overview of the Skull01:08

Overview of the Skull

The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

Design Example: Deciding Thickness of Lubricating Fluid in a Shaft01:23

Design Example: Deciding Thickness of Lubricating Fluid in a Shaft

Effective lubrication between a rotating shaft and its bearing housing is essential in rotating machinery to minimize friction, wear, and energy loss. With carefully controlled thickness and viscosity, the lubricant layer prevents metal-to-metal contact, ensuring smooth operation.
To calculate the required thickness of the lubricant layer, the tangential velocity at the shaft's surface must first be determined. This velocity is calculated by converting the rotational speed to angular velocity...

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...

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...
