Insights

Shortwave infrared (SWIR) otoscopy is feasible for pediatric patients, offering better visualization of middle ear structures and increased contrast for middle ear effusions compared to visible light otoscopy.

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Pediatric Medicine

Background:

  • Visible light otoscopy is standard for examining the ear canal and tympanic membrane.
  • Limitations exist in visualizing deeper middle ear structures and fluid through the tympanic membrane.
  • Shortwave infrared (SWIR) otoscopy is an emerging imaging technique.

Purpose of the Study:

  • To assess the feasibility of SWIR otoscopy in children.
  • To compare SWIR otoscopy with visible light otoscopy for pediatric ear examinations.
  • To identify potential advantages of SWIR otoscopy in visualizing middle ear anatomy and pathology.

Main Methods:

  • Pediatric patients aged 3+ undergoing otolaryngology visits were included.
  • Video otoscopy using both visible light and SWIR was performed.
  • Two otolaryngologists evaluated image interpretability and visualization of specific middle ear structures.

Main Results:

  • Interpretable SWIR images were obtained in 85.1% of ears.
  • SWIR otoscopy showed statistically significant improvement in imaging the promontory and ossicular chain.
  • Enhanced contrast for middle ear fluid was observed with SWIR compared to visible light.

Conclusions:

  • SWIR otoscopy is a feasible imaging modality for pediatric patients.
  • SWIR offers superior visualization of middle ear structures and improved contrast for middle ear effusions.
  • SWIR otoscopy may provide diagnostic advantages in pediatric otology.

Initiation of Translation02:33

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Conservation of Small Populations02:04

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Population Genetics?01:25

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Population Growth00:57

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Finding the Center of Gravity01:03

Finding the Center of Gravity

The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...
