This article examines the complications and risk factors associated with foreign bodies (FBs) in the external auditory canal (EAC). The study analyzed 455 cases over an 8-year period and found that younger age, longer duration of impaction, nongraspable and animate FBs, and FBs touching the tympanic membrane (TM) were independent risk factors for complications. The authors recommend prompt removal of FBs and direct referral to an otolaryngologist for patients with these risk factors. The findings can be used to inform triage and treatment decisions for patients with FBs in the EAC. [Extracted from the article]

Objective: This study aimed to delineate the causal relationship between Ménière's disease and depression. Design: Two longitudinal follow‐up studies. Main Outcome Measures: The 2002‐2013 Korean National Health Insurance Service‐Health Screening Cohort was used. In study I, Ménière's disease patients were 1:4 matched with the control I group for age group, sex, income group and region of residence, and the occurrence of depression was observed. In study II, the depression patients were 1:4 matched with the control II group for the same variables, and the occurrence of Ménière's disease was observed. The stratified Cox proportional hazard model was used. Subgroup analyses were performed according to age and sex. Results: In study I, 6.9% (420/6044) of the Ménière's disease patients and 3.7% (885/24 176) of the control I participants experienced depression. The adjusted hazard ratio (HR) of Ménière's disease for depression was 1.94 (95% confidence intervals [CI] = 1.73‐2.18, P <.001). In study II, 1.6% (490/31 649) of the depression patients and 1.0% (1240/126 596) of the control II participants were diagnosed with Ménière's disease. The adjusted HR of depression for Ménière's disease was 1.58 (95% CI = 1.43‐1.76, P <.001). All age and sex subgroups demonstrated higher HRs of Ménière's disease for depression (study I) and depression for Ménière's disease (study II). Conclusion: Ménière's disease patients showed an increased likelihood of depression. Conversely, depression patients showed an elevated likelihood of Ménière's disease. [ABSTRACT FROM AUTHOR]

Objectives: The present study evaluated the associations between gastroesophageal reflux disease (GERD) and head and neck cancer using a national sample cohort of the Korean population. Design: We designed two studies using data collected from patients aged ≥40 years in the Korean National Health Insurance Service‐National Sample Cohort from 2002 to 2013. Main outcome Measures: Study I included participants with GERD matched 1:2 with controls and analysed the incidences of lip and oral cavity, oropharynx, hypopharynx and larynx cancers. Study II included participants with larynx cancer matched 1:4 with controls and analysed the previous histories of GERD. Head and neck cancer was identified using medical claim codes for surgical, radiation and chemotherapeutic treatments and death records from the National Statistical Office. Crude and adjusted hazard ratios (HRs) were analysed using the Cox proportional hazard model. Crude and adjusted odds ratios (ORs) were analysed using unconditional logistic regression analyses. Subgroup analyses were performed on groups stratified by age and sex. Results: The adjusted HR for larynx cancer was 2.32 (95% confidence interval (CI) = 1.53‐3.52, P < 0.001) in the GERD group. However, the HRs for lip and oral cavity cancer, oropharynx cancer and hypopharynx cancer were not statistically significant (study I). The adjusted OR for GERD was 2.03 (95% CI = 1.40‐2.96, P < 0.001) in the larynx cancer group; consistent results were obtained in subgroup analyses. Conclusion: Gastroesophageal reflux disease increases the risk of larynx cancer. [ABSTRACT FROM AUTHOR]
