The head circumference to chest circumference ratio provided an easy way to detect foetal growth restriction in term infants.

Aim: The head circumference to chest circumference (HC/CC) ratio has been used to identify low birth weight infants in developed countries. This study was conducted to examine whether the ratio could distinguish asymmetrical foetal growth restriction (FGR).

Methods: This retrospective observational study was conducted with 1955 infants (50.

Accuracy and reliability of thermal threshold measurement in the chin using heat flux technique.

Background: Neurosensory disturbance (NSD) occasionally develops in the chin following dental treatments, and evaluation of the involved nerve damage is important for treatment. The thermal-threshold test is a method of evaluating nerve sensations, but it is not widely used because its accuracy and reliability have not yet been determined.

Purpose: This study aimed to determine the accuracy and reliability of thermal-threshold measurement of the chin by using the heat-flux technique.
