Abstract

Insights

Pediatric meningiomas are rare intracranial tumors, predominantly WHO grade I and basally located in this African cohort. No recurrences were observed after complete surgical excision, indicating a favorable prognosis.

Area of Science:

  • Neuro-oncology
  • Pediatric Neurosurgery
  • Tumor Histopathology

Background:

  • Meningiomas are common intracranial tumors, but rare in children.
  • Pediatric meningiomas exhibit distinct behaviors compared to adult counterparts.
  • This study focuses on pediatric meningiomas in an African population.

Purpose of the Study:

  • To investigate the histologic types and characteristics of pediatric meningiomas.
  • To apply the 2016 World Health Organization (WHO) grading system.
  • To analyze data from a predominantly African patient cohort.

Main Methods:

  • Retrospective review of surgical logs and pathology reports.
  • Data extraction included age, sex, tumor location, histology, WHO grade, and recurrence.
  • Analysis of 166 meningiomas over a 19-year period.

Main Results:

  • Nine pediatric cases identified (8 months to 17 years old).
  • Female predominance (1:2 male-to-female ratio); six tumors were basally located.
  • All tumors were WHO grade I; transitional meningiomas were most common, followed by meningothelial. No recurrences reported.

Conclusions:

  • Confirms the rarity of pediatric meningiomas in the studied population.
  • Highlights a predilection for basal location in pediatric meningiomas.
  • Suggests a favorable prognosis for pediatric meningiomas with complete surgical resection.

What is an Experiment?01:12

What is an Experiment?

An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Thomson's e/m Experiment

In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments01:13

Controls in Experiments

When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Randomized Experiments01:13

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Crossover Experiments01:16

Crossover Experiments

Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
