JEP: HPP Vol. 1 and current research.

The 50th birthday of the JEP: Human Perception and Performance is an appropriate occasion to salute its influence in the field. In this celebratory article, the author tries to trace some of the work reported in Volume 1 to current research. He hopes that this might be inspirational to some of its readers.

The Common Expression of INSM1 in HPV-related Oropharyngeal Squamous Cell Carcinomas Is Not Associated With True Neuroendocrine Transformation or Aggressive Behavior.

INSM1 has rapidly emerged as a robust marker for neuroendocrine (NE) differentiation, prompting the use of INSM1 as a standalone marker for NE differentiation in various sites. INSM1 staining could be an especially practical tool for evaluating HPV-associated oropharyngeal squamous cell carcinoma (HPV-OPSCCs) because high-grade NE transformation may be exceedingly difficult to recognize on morphologic grounds alone, even though it portends highly aggressive clinical behavior. The purpose of this study was to determine the incidence of INSM1 expression in HPV-OPSCC and study its role in determining NE transformation and clinical aggressiveness.

Diagnostic Accuracy of Circulating Tumor HPV DNA Testing in Patients With a Lateral Neck Mass.

Importance: The most frequent presenting symptom for patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is a lateral neck mass. Circulating tumor tissue-modified viral (TTMV)-HPV DNA is a unique biomarker produced by the fragmentation of HPV DNA during the degradation of HPV-associated tumors, and its detection and quantitation are currently being used as an adjunct to imaging in monitoring for disease recurrence and may have utility for diagnosis.

Objective: To measure the diagnostic characteristics of TTMV-HPV DNA compared with gold standard tissue biopsy for diagnosing HPV-OPSCC in patients presenting with an indeterminate lateral neck mass.

The Effect of Power Grip on Ulnar Variance A Computed Tomography Study of the Wrist and Elbow.

Although an increase in ulnar variance with power grip is well documented in the medical literature, there is a paucity of information concerning its mechanism. This concept was examined in five healthy individuals using computed tomography of their wrists and elbows. Images were obtained of both joints in the resting position and with maximum power grip.
