“…These capillaries, therefore, play crucial roles in controlling sensory hair cell transduction by regulating endocochlear potential, ion transport, and endolymphatic fluid balance [16,17,18,19,20]. Dysfunction of the cochlear lateral wall is considered a potential etiology for a number of hearing disorders, including NIHL [10,21,22,23].…”

Noise exposure affects the organ of Corti and the lateral wall of the cochlea, including the stria vascularis and spiral ligament. Although the inner ear vasculature and spiral ligament fibrocytes in the lateral wall consist of a significant proportion of cells in the cochlea, relatively little is known regarding their functional significance. In this study, 6-week-old male C57BL/6 mice were exposed to noise trauma to induce transient hearing threshold shift (TTS) or permanent hearing threshold shift (PTS). Compared to mice with TTS, mice with PTS exhibited lower cochlear blood flow and lower vessel diameter in the stria vascularis, accompanied by reduced expression levels of genes involved in vasodilation and increased expression levels of genes related to vasoconstriction. Ultrastructural analyses by transmission electron microscopy revealed that the stria vascularis and spiral ligament fibrocytes were more damaged by PTS than by TTS. Moreover, mice with PTS expressed significantly higher levels of proinflammatory cytokines in the cochlea (e.g., IL-1β, IL-6, and TNF-α). Overall, our findings suggest that cochlear microcirculation and lateral wall pathologies are differentially modulated by the severity of acoustic trauma and are associated with changes in vasoactive factors and inflammatory responses in the cochlea.

“…Third, data on the severity of nutritional anemia and SSNHL and the prognosis of affected patients were unavailable. Finally, although we adjusted for numerous potential confounders such as obesity, smoking, alcohol consumption, blood pressure, fasting blood glucose, total cholesterol, and CCI scores, there could have been other confounders that we did not adjust for, such as history of noise exposure, which could have influenced the results [39,40]. Future study with the participants with specified types of anemia and SSNHL will delineate the current questions.…”

Previous studies have suggested an association of anemia with hearing loss. The aim of this study was to investigate the association of nutritional anemia with sudden sensorineural hearing loss (SSNHL), as previous studies in this aspect are lacking. We analyzed data from the Korean National Health Insurance Service-Health Screening Cohort 2002–2015. Patients with SSNHL (n = 9393) were paired with 37,572 age-, sex-, income-, and region of residence-matched controls. Both groups were assessed for a history of nutritional anemia. Conditional logistic regression analyses were performed to calculate the odds ratios (ORs) (95% confidence interval, CI) for a previous diagnosis of nutritional anemia and for the hemoglobin level in patients with SSNHL. Subgroup analyses were conducted for age and sex. Age, sex, income, and region of residence were stratified. Obesity, smoking, drinking alcohol, systolic/diastolic blood pressure, fasting blood glucose, total cholesterol, and the Charlson Comorbidity Index were considered in the regression models. Nutritional anemia was present in 4.8% (449/9393) of patients with SSNHL and 4.0% (1494/37,572) of controls (p < 0.001). The SSNHL group demonstrated 1.20-fold higher odds for nutritional anemia (95% CI = 1.08–1.34, p = 0.001). Hemoglobin levels were not associated with SSNHL. In subgroups <60 years old, there was a consistent positive association of nutritional anemia with SSNHL (adjusted OR = 1.55, 95% CI = 1.11–2.15, p = 0.010 for men <60 years old, and adjusted OR = 1.22, 95% CI = 1.02–1.45, p = 0.028 for women <60 years old). Nutritional anemia, but not hemoglobin level, was associated with an increased risk of SSNHL.

“…Pre-existing hearing loss-Pre-existing hearing loss at MDR-TB diagnosis commonly originates from previous exposure to ototoxic drugs, noise exposure, advanced age, or idiopathic SNHL (Tysome JR 2016). Particularly, because acoustic stimuli increase permeability of cation channels such as MET and TRP, the noise exposure also increases the AG uptake and directly accelerates intracellular accumulation of AGs within hair cells (Hayashida et al 1985;Park et al 2018;Ricci et al 2005). Age-related hearing loss, or presbycusis, caused by the degeneration of cochlear cells is also a major cause of preexisting hearing loss (Hu et al 2018).…”

Adverse outcome pathway for aminoglycoside ototoxicity in drug-resistant tuberculosis treatment

Individuals treated for multidrug-resistant tuberculosis (MDR-TB) with aminoglycosides (AGs) in resource-limited settings often experience permanent hearing loss. However, AG ototoxicity has never been conceptually integrated or causally linked to MDR-TB patients' pre-treatment health condition. We sought develop a framework that examines the relationships between pre-treatment conditions and AG-induced hearing loss among MDR-TB-infected individuals in sub-Saharan Africa.

Cochlear Damage Caused by the Striking Noise of Titanium Head Golf Driver

Abstract: Overexposure to impact noise caused by hitting of titanium head golf driver may be hazardous to the cochlea, and repetitive exposure may induce greater damage than continuous exposure.
