BACKGROUND: Otitis media with effusion (OME) frequently leads to vestibular symptoms in children. However, young children face difficulty expressing their symptoms due to their limited language abilities. METHODS: The balance of study and patient group evaluated with computer dynamic posturography, single-leg stance test with eyes closed and regular Head Impulse Test. The study group was assessed once again after the insertion of a ventilation tube two months later. RESULTS: In the Sensory Organization Test, the scores for conditions 5, 6, and composite equilibrium of the preoperative patient group were notably lower compared with both the control and postoperative patient groups (p < 0.05). Additionally, a significant correlation was found between single-leg stance test with eyes closed results and conditions 5, 6, and composite equilibrium scores. CONCLUSION: The impact of OME on the vestibular system is negative. This effect can be objectively assessed using Computer Dynamic Posturography and following tube insertion, there is a notable improvement in vestibular function. Furthermore, the single-leg stance (SLS) test with eyes closed has shown its reliability in assessing balance disorders, notably in children with OME. LEVEL OF EVIDENCE: 2 Laryngoscope, 134:4126-4133, 2024.

Vaccine-induced immunity wanes over time and warrants booster doses. We investigated the long-term (32 weeks) immunogenicity and safety of a third, homologous, open-label booster dose of TURKOVAC, administered 12 weeks after completion of the primary series in a randomized, controlled, double-blind, phase 2 study. Forty-two participants included in the analysis were evaluated for neutralizing antibodies (NAbs) (with microneutralization (MNT50) and focus reduction (FRNT50) tests), SARS-CoV-2 S1 RBD (Spike S1 Receptor Binding Domain), and whole SARS-CoV-2 (with ELISA) IgGs on the day of booster injection and at weeks 1, 2, 4, 8, 16, 24, and 32 thereafter. Antibody titers increased significantly from week 1 and remained higher than the pre-booster titers until at least week 4 (week 8 for whole SARS-CoV-2) (p < 0.05 for all). Seroconversion (titers ≥ 4-fold compared with pre-immune status) persisted 16 weeks (MNT50: 6-fold; FRNT50: 5.4-fold) for NAbs and 32 weeks for S1 RBD (7.9-fold) and whole SARS-CoV-2 (9.4-fold) IgGs. Nine participants (20.9%) tested positive for SARS-CoV-2 RT-PCR between weeks 8 and 32 of booster vaccination; none of them were hospitalized or died. These findings suggest that boosting with TURKOVAC can provide effective protection against COVID-19 for at least 8 weeks and reduce the severity of the disease.
