Summary
The Corneometer and hydration probe (HP) are accurate, objective devices for measuring skin hydration. These tools demonstrate excellent reproducibility and high correlation, aiding in informed skin care decisions.
Area of Science:
- Dermatology
- Biomedical Engineering
- Cosmetic Science
Background:
- Objective measurement of skin hydration is crucial.
- Various skin hydration measurement devices exist.
- Evaluating the reliability of widely used devices is necessary.
Purpose of the Study:
- To assess the reproducibility of the Corneometer and hydration probe (HP).
- To determine the correlation between clinical evaluation and these devices.
- To compare device performance across different measurement sites.
Main Methods:
- Prospective comparative clinical trial with 184 healthy volunteers.
- Skin hydration measured using Corneometer and HP on ventral forearm, dorsal forearm, and shin.
- Intraclass correlation coefficient (ICC) for reproducibility, Pearson's correlation coefficient (PCC) for correlation, and linear regression for xerosis severity scale (XSS) analysis.
Main Results:
- Both Corneometer and HP exhibited excellent reproducibility (ICC: 0.954-0.986).
- High positive correlations were found between the devices (PCC: 0.708-0.737).
- No statistically significant correlation was found between device measurements and xerosis severity scale (XSS).
Conclusions:
- The Corneometer and HP are accurate and objective skin hydration measurement devices.
- Device performance is consistent across different anatomical sites.
- These reliable devices support better understanding of skin condition and improved skincare decisions.

731
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

01:13Equipments Used to Measure Body Temperature
978
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
