Summary
A new interarytenoid assessment protocol reliably standardizes the description of laryngeal anatomy for pediatric dysphagia. This method shows substantial agreement among raters, improving diagnostic accuracy.
Area of Science:
- Otolaryngology
- Pediatric Medicine
- Anatomy
Background:
- The Benjamin-Inglis classification system has limitations in differentiating type 1 laryngeal clefts from normal anatomy.
- There is no validated protocol for systematically evaluating interarytenoid mucosal height.
Purpose of the Study:
- To propose and test the reliability of the interarytenoid assessment protocol.
- To standardize the description of interarytenoid anatomy.
Main Methods:
- Retrospective review of 30 endoscopic videos of the interarytenoid assessment protocol.
- Four blinded otolaryngologists evaluated the videos, assessing protocol completion time and interrater/intrarater reliability using Cohen's κ coefficient.
Main Results:
- The protocol demonstrated substantial interrater reliability (κ = 0.71) and intrarater reliability (mean κ = 0.70).
- Agreement between raters and the operating surgeon was also substantial (mean κ = 0.62).
- Median protocol completion time was 144 seconds.
Conclusions:
- The interarytenoid assessment protocol is a reliable method for describing interarytenoid anatomy.
- The protocol is quick to complete and shows substantial reliability, supporting its use in standardizing descriptions for pediatric dysphagia.

01:29Reliability and Validity
13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

03:38Measurement: Standard Units
79.9K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

02:37Standard Enthalpy of Formation
49.2K
Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...
