Is gestational diabetes a risk factor for neonatal hearing loss?

Aim: Newborn hearing screening is important for early detection of hearing loss in newborns. Gestational diabetes is a metabolic disease that can occur in pregnancy and cause complications such as those in the other diabetes mellitus patients. As uncomplicated gestational diabetes has not been described as a cause for prenatal complications in the literature, this study aimed to determine whether gestational diabetes is a risk factor for hearing impairment among newborns.Methods: This retrospective study included infants born between 2015 and 2017. The infants were divided into two groups: Control group consisted of 100 randomly selected children of healthy mothers. Study group consisted of 79 infants whose mothers had gestational diabetes mellitus. Exclusion criteria included other risk factors and 8 infants were excluded from the study due to risk factors other than gestational diabetes mellitus. The results of transient evoked otoacoustic emissions in infants of mothers with gestational diabetes were compared with those of infants of healthy mothers.Results: In this study, we compared transient evoked otoacoustic emission results of 71 infants of gestational diabetic mothers with 100 infants of healthy mothers. All the infants of healthy mothers, as well as the infants of mothers with gestational diabetes without risk factors, passed the transient evoked otoacoustic emission test. Conclusions: There was no difference detected in the hearing screening results between infants of mothers with gestational diabetes and infants of healthy mothers

An unusual peripheric facial paralysis onset

WOS: 000419795800015Peripheric facial paralysis may be observed primary or secondary causes. Firearm injuries may cause facial paralysis via direct injury or ballistic effects. Ballistic effects may be observed far beyond the bullet trace. In this article we present an unusual late peripheric facial paralysis onset related with ballistic effect a firearm injury to the left maxillary sinus. Due to late onset of facial paralysis after firearm injury; differential diagnosis and ballistic effects have been discussed

Tegmen Tympani Defect and Brain Herniation Secondary to Mastoid Surgery: Case Presentation

Brain herniation into the middle ear is very rarely seen. In addition to reasons like congenital factors, trauma, and infection, tegmen defect may develop as a result of iatrogenic events secondary to chronic otitis media surgery with or without cholesteatoma. Since it may cause life-threatening complications, patients must be evaluated and monitored for tegmen defect. In this paper, diagnosis and treatment of a brain herniation case due to iatrogenic tegmen defect were described along with relevant literature

Evaluation on Shear Bond Strength of Different Glass Ionomer and Hydroxy Apatite Cements Used in Ossiculoplasty

Background: Glass ionomer cements (GIC) have been widely used in dentistry for many years. In recent years, GIC have also been used for ossiculoplasty. The bond strength of GIC used in ossiculoplasty and the way they may change over the years in the cementation area are being questioned. The bonding strength of the substance may be of importance for long-term outcomes. Aims: The aim of this study was to investigate the bond strength of different GIC on ossicles. Study Design: In vitro study. Methods: Twenty ossicles were obtained from patients who had undergone ear surgery. All specimens were randomly divided into four subgroups. All specimens were inserted into a specially designed apparatus for shear bond strength (SBS) testing. The tested materials [Aqua Meron (AM), Aqua Cem (AC), Ketac Cem (KC), and Otomimix CPB (OH)] were prepared and applied according to the manufacturer’s instructions. The SBS was tested using a universal testing machine at a crosshead speed of 0.5 mm/min. Results: The mean SBSs were found to be 13.28 MPa, 23.43 MPa, 8.51MPa, and 1.78 MPa for AM, AC, KC, and OH, respectively. AC had the highest SBS, which was statistically significantly different from that of KC and OH (p<0.05). Both AM and KC had higher SBS than OH (p<0.05). Conclusion: The results obtained in this study by investigating the bone-bonding strength of cements widely used in ossiculoplasty demonstrate that some of these substances have a greater ability to bond to ossicles compared to others. Further clinical investigations are needed to test different parameters
