Abstract:
Teprotumumab is a human monoclonal antibody and IGF-1R (insulin-like growth factor 1 receptor) inhibitor approved for treatment of thyroid eye disease in adults. Recent clinical trials have demonstrated side effects, notably hearing loss, in the treatment cohort as compared with the placebo cohort. These unexpected otologic side effects may be understood through a mechanistic understanding of IGF-1 (insulin-like growth factor 1). As otolaryngologists who historically play a significant role in the multidisciplinary treatment of thyroid disease and its associated complications, we should be aware of and monitor the otologic side effects of teprotumumab. Clinicians who prescribe teprotumumab should strongly consider monitoring patients' hearing with an audiologist and otolaryngologist.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
