AI Article Synopsis
- Firefighters are exposed to various carcinogens that could increase their risk of head and neck cancer, but previous studies have had limitations in accounting for smoking and alcohol use.
- This study used data from a large case-control study in the greater Boston area, focusing on men with an occupational history as firefighters.
- Although no overall significant association was found, there was a notably high risk for hypopharyngeal and laryngeal squamous cell carcinoma among professional firefighters with little to no smoking history, indicating a potential link to their occupational exposure over time.
Article Abstract
Objective: Firefighters are exposed to a wide variety of carcinogens during the line of duty, including several associated with head and neck cancer. Existing studies assessing head and neck cancer risk with firefighting have predominately included occupational cohorts or registry data, which are limited by inability to adjust for smoking and alcohol consumption-major risk factors for head and neck cancer. Our objective was to assess the risk of head and neck cancer among men with an occupational history as a firefighter.
Methods: This work was conducted using male subjects from a large population-based case-control study of head and neck cancer from the greater Boston area using self-reported occupational history (718 cases and 905 controls).
Results: An occupational history as a firefighter was reported for 11 cases and 14 controls. Although no significant association was observed overall, we observed substantial increased risk for hypopharyngeal and laryngeal squamous cell carcinoma among professional municipal firefighters who had a light or no smoking history (OR=8.06, 95% CI 1.74 to 37.41), with significantly increasing risk per decade as a firefighter (OR=2.10, 95% CI 1.06 to 4.14).
Conclusion: Professional municipal firefighters may be at increased risk for hypopharyngeal and laryngeal squamous cell carcinoma due to carcinogenic exposures encountered during the line of duty.

Department of Otorhinolaryngology Head and Neck Surgery, Beijing Tiantan Hospital, Capital Medical University, No. 119, South Fourth Ring Road West, Fengtai District, Beijing, 100070, China.
Background: This study aims to identify a pathogenic SDHD mutation associated with hereditary head and neck paraganglioma (HNPGL) in a Chinese family and to explore its implications for genetic counseling.
Methods: The study involved a family with 15 members spanning three generations. A 31-year-old patient (II-4) was diagnosed with a left parotid gland tumor and a right carotid body tumor, while both the father and elder sister had right carotid body tumors, and the third sister had bilateral carotid body tumors.
Influence of the wet-ear state on the outcomes of tympanic membrane repair under ear endoscopy: a prospective case-control study.

Background: To prospectively determine whether tympanoplasty for tympanic membrane perforation (TMP) in wet ears impacts recovery.
Methods: We prospectively enrolled 32 TMP patients (2021-2023) and divided them into the wet-ear (14 patients) and dry-ear groups (18 patients), according to the presence of middle-ear secretions/edema. All patients underwent high-resolution thin-slice computed tomography, ear endoscopy, and pure tone audiometry.

During nasal polyp (NP) development, activated T cells differentiate into T helper (Th) 1, Th2, and Th17 cells. Additionally, regulatory T cells (Tregs) that have an immune suppressive function are involved in the pathophysiology of chronic rhinosinusitis (CRS) with NP (CRSwNP). Tregs can act as effector cells that produce inflammatory cytokines, such as interleukin (IL)-17A.

Aberrant immune responses to viral pathogens contribute to pathogenesis, but our understanding of pathological immune responses caused by viruses within the human virome, especially at a population scale, remains limited. We analyzed whole-genome sequencing datasets of 6,321 Japanese individuals, including patients with autoimmune diseases (psoriasis vulgaris, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), pulmonary alveolar proteinosis (PAP) or multiple sclerosis) and coronavirus disease 2019 (COVID-19), or healthy controls. We systematically quantified two constituents of the blood DNA virome, endogenous HHV-6 (eHHV-6) and anellovirus.
