Introduction: Women undergoing infertility treatment are often tagged with negative labels, subjected to negative reactions and behaviors by laypeople (public stigma), and they internalize these negative values (self-stigma). As self-stigma is associated with poor mental health, a measure is needed to determine the current state of public stigma in Japan and to evaluate the effectiveness of efforts to reduce it. However, existing instruments to measure public stigma in this context are limited.

Background: Over the past 2 years, researchers have used various medical licensing examinations to test whether ChatGPT (OpenAI) possesses accurate medical knowledge. The performance of each version of ChatGPT on the medical licensing examination in multiple environments showed remarkable differences. At this stage, there is still a lack of a comprehensive understanding of the variability in ChatGPT's performance on different medical licensing examinations.

The resection of middle ear paragangliomas can be challenging given their vascular nature and the small volume of the tympanic cavity, particularly when the tumor in the hypotympanum is close or attached to the internal carotid artery (ICA). We performed combined underwater endoscopic and microscopic surgery for a Class B1 middle ear paraganglioma according to the modified Fisch classification. The suspicious bone in the hypotympanum and around the petrous ICA was drilled with underwater endoscopy.

Objective: The development of acquired middle ear cholesteatoma is associated with a single nucleotide polymorphism, 538G>A, in the human adenosine triphosphate-binding cassette transporter C11 (ABCC11) gene, which is a determinant of the earwax morphotype, such as wet- and dry-type earwax; however, the mechanism underlying this association is unclear. We focused on the earwax pH and aimed to elucidate the mechanism between ABCC11 genotypes and acquired middle ear cholesteatoma.

Study Design: Prospective observational study.
