Item Medial olivary complex reflex in term newborns with hyperbilirubinemia(2021) Culhaoglu, Belde; Erbek, Selim S.; İnce, Deniz Anuk; Ecevit, Ayse Nur; Erbek, Seyra; 0000-0002-8453-6069; 34116320; AAJ-2445-2021Objective: This study aimed to compare the integrity of the efferent auditory pathways of newborns that had high hyperbilirubinemia levels and required treatment due to these and healthy newborns. Methods: Term-born (37 weeks or later) infants that were brought to the Newborn Polyclinic of the Baskent University Hospital were included in the study. The study included a total of 84 infants including healthy newborns (n = 42) and those that had jaundice and were receiving phototherapy (n = 42). After conducting a general otorhinolaryngology examination on all newborns included in the study, Transient Otoacoustic Emission (TEOAE) test was carried out in the absence and presence of contralateral noise. The obtained contralateral suppression values were compared between the two groups. Results: In the TEOAE test, the responses obtained at 1 kHz in the newborns receiving phototherapy were found to be lower. The difference between the groups was significant (p = 0.038). The rates of suppression presence at 2 kHz, 2.8 kHz and total OAE were found significantly higher (p < 0.05) in the group not receiving phototherapy. Among the phototherapy-receiving infants, the hyperbilirubinemia levels of the infants in whom suppression was obtained in the contralateral suppression test did not show a statistically significant difference in comparison to those in whom suppression was not obtained (p > 0.05). Conclusion: Based on the obtained data, hyperbilirubinemia may have a disruptive effect on the efferent auditory system in newborns. Consequently, we are of the opinion that, in addition to hearing screening in risky newborn infants, a MOC suppression test would be useful.Item Multifunctional Phototherapy Device Design(2019) Aksahin, MehmetToday, phototherapy devices are used to treat newborn jaundice. However, there are some cases that the commercial phototherapy devices are inadequate. Most of the device are controlled only at the certain interval that prevents instantaneous monitoring the newborn's vital parameters. For other cases, devices are one-way lighting. In addition, when the baby is taken away from the device, unnecessary lighting causes the decrease in LED's lifetime. In the scope of the study, intensive phototherapy device was developed to eliminate deficiencies that are mentioned above. Properties of the developed phototherapy device are; Automatic detection of newborn's presence, double-sided illumination, continuous monitoring with IP webcam, temperature measurement of the environment and also newborn's body temperature. The light intensity of the device was measured with a photometer as 28.6 mu W/cm(2)/nm that was obtained from 460nm wavelength LED illumination in both top and bottom in accordance with the American Academy of Pediatrics (AAP) guideline.
