Filter by:In Traditional Medicine, auricular acupressure (AA) is one of the non-pharmacological treatment methods commonly utilized due to its safety and convenience. AA involves the application of a taped seed of Vaccaria (with a diameter of 2mm) on specific ear acupoints to manage various disorders. Among these, chronic lower back pain is prevalent. According to Traditional Medicine, the Kidney point is selected for this condition due to the belief that "The lumbar region is the house of the Kidneys". However, evidence supporting this correlation is still lacking. In this study, the aim is to assess the relationship between the Kidney point and the lumbar region by monitoring changes in skin temperature through the application of AA on this acupoint.
Background: There are many post-procedural treatments touted to improve comfort and decrease downtime, but very few prospective randomized studies. Aims: To analyze the safety and efficacy of a post-procedural biotech cellulose mask Patients/Method: Fifteen patients undergoing either a microneedling with radiofrequency (n=5), non-ablative fractional (n=5), or full erbium;YAG resurfacing (n=5) treatment were randomized to receive a Velez biotech cellulose mask on one side of the face for 30 minutes after the procedure and for two hours a day until healed. Canfield Visia photos and thermal photographs were taken 30 minutes after the procedure and daily until healed. The investigator and blind evaluators reviewed the photos and subjects answered daily questionnaires.
The global populace is at growing risk of heat-related illness due to climate change and accompanying increases in the intensity and regularity of extremely hot temperatures. In heat-exposed persons, heat gain from the environment and metabolism initially exceeds the rate of heat dissipation from the skin. Heat is stored in the body, causing core and skin temperatures to rise, which in turn triggers autonomically mediated elevations in cutaneous blood flow and sweating to facilitate heat loss. If conditions are compensable, heat loss increases until it balances total heat gain. At this point, the rate of heat storage falls to zero (i.e., heat balance is achieved) and body temperature stabilizes, albeit at a level elevated from thermoneutral conditions. If, however, the maximal achievable rate of heat dissipation is insufficient to offset heat gain, conditions are uncompensable, and prolonged exposure will cause a continual rise in core temperature that can compromise health if left unchecked. The environmental limits of compensability (i.e., the temperatures/humidities above which heat balance can not be maintained) are therefore an important determinant of survival during prolonged heat exposure. Evaluating this limit and how it can be modified (e.g., by behavior or individual factors like age or sex) is an increasingly important and active field of study. Contemporary evaluations of the environmental limits of compensability utilize "ramping protocols" in which participants are exposed to increasing levels of temperature or humidity (in 5-10 min stages) while core temperature is monitored. It is generally observed that core temperature is relatively stable (or rises slightly) in the early stages of exposure but undergoes an abrupt and rapid increase as heat stress becomes more severe. The conditions (e.g., wet-bulb temperature or wet-bulb globe temperature) at this "inflection point" are taken as the limits of compensability. That is, it is assumed that inflection corresponds to the demarcation point, below which core temperature would remain stable for prolonged periods (theoretically indefinitely if hydration is maintained) but above which heat loss is insufficient to offset heat gain, causing core temperature to rise continuously. Despite the increasing use of these protocols, no study has clearly demonstrated their validity for identifying the environmental limits of compensability. The goal of this project is therefore to assess the validity of ramping protocols for determining the ambient conditions above which thermal compensation is not possible. Enrolled participants will complete four experimental trials in a climate-controlled chamber: one ramping protocol followed by three randomized fixed-condition exposures. In the ramping protocol, participants will rest in 42°C with 28% relative humidity (RH) for 70 min, after which RH will be increased 3% every 10 min until 70% RH is achieved. The core (esophageal) temperature inflection point will be determined. For the fixed-condition exposures, participants will rest in i) 42°C with RH ~5% below their individual inflection point (below-inflection condition), ii) 42°C with RH ~5% above their individual inflection point (above-inflection condition), and iii) 26°C with 45% RH (control condition). Comparing the rate of change in esophageal temperature between each fixed-condition exposure will provide important insight into the validity of ramping protocols for identifying the limits of compensability.
In pediatric patients, the accuracy of body temperature measured with an esophageal temperature probe placed through the gastric lumen of the supraglottic airway device is investigated.
Cryotherapy after surgery is widely utilised and has numerous practical applications for post-operative rehabilitation. Previous research has suggested that during cold therapy, the skin temperature of the knee should be reduced to 10-15°C to maximise the therapeutic benefits of cooling while avoiding the risk of cold injuries such as nerve damage and frostbite (Wilke and Weiner, 2003; Bleakley, McDonough and MacAuley, 2004). However, a recent study noted that where cryocompression devices have previously been used to reduce the skin temperature <10°C, no complications relating to the device have been reported, suggesting that the risk to the user at these lower temperatures is minimal (Bellon et al., 2019). The temperature range at which a cryocompression device should be set in order to achieve a skin temperature within the therapeutic range of 10-15°C is unknown. Furthermore, there is evidence to suggest that the temperature setting of the device does not equal that to which the skin is reduced (Selfe et al., 2009). Therefore, it is not sufficient to assume that the temperature setting of a cryocompression device accurately reflects skin temperature. Modern cryotherapy devices often consist of some sort of cuff that can be wrapped around the knee, with a connecting tube to a central unit that supplies and circulates ice-water to and from the cuff in order to cool the intended body part. Such devices offer differing levels of control over the temperature of the ice-water as it leaves the central unit, but nothing is known about how this correlates to the skin temperatures that are achieved during a cryotherapy treatment. The aim of this study is to determine the ability of five different cryocompression.devices to effectively lower the skin temperature of the treatment area to within the therapeutic range.

Furthermore, there is evidence to suggest that the temperature of the device does not equal that to which the skin is reduced, plus different devices do not achieve the same reduction in skin temperature despite the ice-water within the knee sleeve being maintained at similar temperatures (Selfe et al., 2009). Therefore, it is not sufficient to assume that the temperature setting of a cryo-compression device reflects the skin temperature achieved. The aim of this study is to determine which temperature of ice-water flowing through a Physiolab S1 cryocompression device is able to reduce skin temperature around the knee to within the previously stated therapeutic range.
The primary objective of this study is to determine if the Infrared Cameras, Inc (ICI) FMX 400 infrared (IR) Class 1 infrared thermal camera (IRT) system is comparable to oral, forehead, and ear thermometers for determining human body temperature.
Based on client needs and technological requirements, a wearable sensor device was designed and developed using principles of 'social innovation' design. The device underwent multiple iterations in product design and engineering based on user-feedback and then following pre-clinical testing, a techno-feasibility study and clinical trial were undertaken in a tertiary-care, teaching hospital in Bangalore, India. Clinical trial phases I and IIa {studies/pilot studies designed to demonstrate clinical efficacy or biological activity ('proof of concept' studies)} for evaluation of safety and efficacy were undertaken in the following sequence: first with healthy adult volunteers; then healthy mothers; healthy babies; stable babies in the Neonatal intensive care unit (NICU) and then a baby with morbidities. Time-stamped skin temperatures obtained at 5-minute intervals over a 1-hour period from the device secured on upper arms of mothers and abdomen of neonates were compared against readings from thermometers used routinely in clinical practice, radiant warmer and multimodal sensor
Observational study to compare core temperatures obtained by 6 methods in patients undergoing cardiac surgery under cardiopulmonary bypass.
An increasing number of children undergo Magnetic Resonance Imaging (MRI). In MRI, radio waves and magnetism are used to form images of the body's interior, to diagnose and monitoring diseases in children. Many children are sedated to be able to collaborate with the MRI procedure. Sedation and general anesthesia cause the child to some extent to lose the ability to regulate his or her own bodytemperature. MRI rooms are most often cold due to the function of the magnet, leading to a risk of hypothermia in young children. Conversely, the MRI scanner generates radio frequencies that are absorbed by the body and converted to heat, which especially in small children due to their large surface area can potentially result in an increase in bodytemperature. In this study we therefore want to investigate changes in bodytemperature in children who are undergoing MRI- scanning within the Neuroanesthesiology Clinic. Furthermore, we want to define possible risk factors for possible temperature changes. Our hypothesis: Children undergoing MRI scanning increase in bodytemperature.
