Mallampati Scoring And Its Relation To Obstructive Sleep Apnea, Austin Korczak
Mallampati Scoring And Its Relation To Obstructive Sleep Apnea, Austin Korczak
Honors Capstones
According to the American Sleep Apnea Association potentially 80% of moderate to severe cases of Obstructive Sleep Apnea (OSA) go undiagnosed with even optimistic estimates stating that at least 22 million Americans are afflicted by the disorder. These numbers are expected to continue to increase due to the rising rates of obesity in America. As a result, reliable criteria that can help physicians accurately predict the presence of an underlying sleep disorder, whose symptoms are masked during the day, is highly sought after. The objective of this research is to begin defining these criteria via a literature review of articles …

Obstructive sleep apnea (OSA) is characterized by recurrent upper airway obstruction during sleep. OSA leads to high cardiovascular morbidity and mortality. The pathogenesis of OSA has been linked to a defect in neuromuscular control of the pharynx. There is no effective pharmacotherapy for OSA. The objective of this study was to determine whether upper airway patency can be improved using chemogenetic approach by deploying designer receptors exclusively activated by designer drug (DREADD) in the hypoglossal motorneurons. DREADD (rAAV5-hSyn-hM3(Gq)-mCherry) and control virus (rAAV5-hSyn-EGFP) were stereotactically administered to the hypoglossal nucleus of C57BL/6J mice. In 6–8 weeks genioglossus EMG and dynamic MRI …

Empty Nose Syndrome—What Do We Know?, Ethan Frank, Christopher Church Md
Loma Linda University Student Journal
Empty nose syndrome is a complication of nasal surgery wherein patients develop a persistent, debilitating sense of nasal obstruction and dyspnea despite clear nasal cavities. It is characterized by a discrepancy between prominent subjective symptoms and near total lack of objective findings, making it difficult to diagnose. The pathophysiology of empty nose syndrome is a complex mix of aerodynamic, physiologic, and neurological changes leading to altered airflow and diminished sensory function. Evolving treatment options consist of medical symptom control or surgical reconstruction.
