This series represents one of the largest single-institution experiences of AIFRS published to date. Timely diagnosis is necessary to improve patient outcomes and limit morbidity. Maintaining a high index of suspicion in at-risk patient populations, followed by prompt evaluation and management, is crucial in suspected AIFRS. The presence or absence of certain findings appear to correlate with biopsy results and may aid in appropriately gauging clinical suspicion for the presence of AIFRS.

Elevated HbA1c levels are found in ED patients with elevated random plasma glucose values. ED patients with hyperglycemia may warrant referral for diabetes testing.

Patients with ID thyroid cancer tend to be older at presentation, have higher stage disease, and are more likely to be male compared with patients with NID thyroid cancer. There does not appear to be a significant difference in the size, pathology, or behavior of the tumor at presentation between ID and NID thyroid cancers. These findings imply that improved detection may not represent the only cause of the increased incidence of thyroid cancer.

We found that EERD that affects the pediatric upper airway was associated with esophagitis in more than half of the patients. The usefulness of 4-level biopsies during esophagoscopy and concomitant airway endoscopy will be discussed.
