This study aims to assess epiglottic calcification on neck computed tomography (CT) and explore associations with age, sex, and medical history. This retrospective observational study evaluated 203 high-resolution neck CT scans from adult patients between 2023 and 2025. Patients with structural abnormalities, prior neck surgery, or poor-quality scans were excluded. Calcification was assessed on the base, body, and stalk of the epiglottis by anatomical location on the epiglottic wall (anterior, posterior, or full thickness) and severity of the lesion (mild, moderate, severe). Two experienced observers independently reviewed all scans, resolving discrepancies by consensus. Only 5 out of 203 patients (2.46%) showed epiglottic calcification, all males aged over 60. Calcifications were primarily located in the body and base, with no involvement of the stalk and no severe or full-thickness cases. No associated epiglottic deformities were observed. Epiglottic calcification is predominantly affecting elderly males. The absence of symptoms suggests a benign, age-related change rather than a pathological condition. Recognition on CT is essential to prevent unnecessary procedures.

This study examined whether maternal exposure to TZ at an acceptable daily intake (ADI) dosage during lactation could induce neurotoxicity in male rat pups and to investigate the potential underlying mechanism. Twelve rat dams at postnatal day 2 (PND2) were split equally into control (received vehicle), and TZ-treated (received TZ 7.5 mg/kg) groups. Administration was through oral gavage, once daily for 20 days (from PND2 to PND21). The pups' exposure to TZ was via breastfeeding. On PND22, male pups' brain tissues were collected for histopathological, immunohistochemical, biochemical, and gene expression analyses. Maternal TZ exposure during lactation led to brain tissue damage in rat pups, with resultant neuronal atrophy, nuclear condensation, perineuronal halos, capillary congestion, wide pericapillary spacing, hemorrhage, and neuropil vacuolation in the prefrontal cortex, cerebellar cortex, and hippocampus. Also, lactational TZ exposure was associated with oxidative stress (raised malondialdehyde, reactive oxygen species with total antioxidant capacity decline); oxidative DNA damage (overexpression of 8-OHdG protein); endoplasmic reticulum stress (upregulated XBP-1, BIP, CHOP, and JNK genes); autophagy suppression (upregulated p62 gene, downregulated Beclin-1 gene, decreased LC3-II at both protein and gene levels); synaptogenesis impairment (decreased synaptophysin protein expression and increased acetylcholinesterase activity level); inflammation (raised TNF-α, IL-1β, IL-6 with IL-10 decline).
