    Dev Period Med 2015 Jul-Sep;19(3 Pt 1):247-53
    The first decade of the 21st century saw the worldwide spread of therapeutic hypothermia as a beneficial therapeutic procedure in neonates with hypoxic-ischemic encephalopathy. New guidelines for the resuscitation of newborns confirm that therapeutic hypothermia should be the standard method of treatment offered to neonates with acute perinatal hypoxia. The quality of care which an asphyxiated newborn receives during and immediately after resuscitation, as well as the mode of preparation for transport, can have a significant impact on improving the outcome, but it can also result in the deterioration of neonates treated with hypothermia.

    Purpose: To compare temperature profile characteristics (on and off eye) of two patient-applied heat therapies for meibomian gland dysfunction (MGD): an eye mask containing disposable warming units (EyeGiene(®)) and a microwave-heated flaxseed eye bag(®) (MGDRx EyeBag(®)).

    Methods: In vitro evaluation: surface temperature profiles of activated eye masks and heated eye bags(®) (both n=10), were tracked every 10s until return to ambient temperature. Heat-transfer assessment: outer and inner eyelid temperature profiles throughout the eye mask and eye bag(®) treatment application period (10min) were investigated in triplicate. Read More
