[A MULTICENTER CLINICAL SURVEY ABOUT THE PREVALENCE OF JAPANESE CYPRESS POLLINOSIS AND THE EFFICACY OF SUBLINGUAL IMMUNOTHERAPY WITH JAPANESE CEDAR POLLEN EXTRACT DURING JAPANESE CYPRESS POLLEN DISPERSAL PERIOD].

Background: Little is known whether sublingual immunotherapy using Japanese cedar pollen extract (cedar SLIT) is effective for not only Japanese cedar pollinosis but also Japanese cypress pollinosis. We investigated the prevalence rate of Japanese cypress pollinosis, efficacy of cedar SLIT on cypress pollinosis and patients' wish to receive cypress SLIT.

Methods: We investigated a multi-center (31 institutions), cross-sectional survey using a self-administrated questionnaire with four questions for patients received cedar SLIT aged from 5 to 69 years old.

Mapping naso-ocular symptom scores to EQ-5D-5L utility values in Japanese cedar pollinosis.

Background: The total naso-ocular symptom score (TSS) is widely used as an endpoint to evaluate the severity of seasonal allergic rhinitis. However, it is not a generic preference-based measure. We sought to develop an algorithm for mapping between the TSS and health utility in Japanese cedar pollinosis (JCP).

Angiotensin-converting enzyme (ACE) I/D genotype and renal ACE gene expression.

Background: The angiotensin-converting enzyme (ACE) I/D genotype affects serum ACE levels and the onset and progression of renal disease, but little is known about the mechanism. We investigated a possible association between the ACE I/D genotype and renal ACE mRNA levels in healthy subjects.

Methods: Renal biopsy samples were obtained from 50 healthy kidney donors.

[Pathogenesis mechanism in ear fullness in otosclerosis].

To clarify the mechanism underlying ear fullness in otosclerosis, we studied the relationship between clinical features and examinations. Subjects were 116 otosclerosis patients (140 ears). The presence or absence of ear fullness was judged from a questionnaire in initial diagnosis or a chart description.

Acinic cell carcinoma of maxillary sinus.

Acinic cell carcinoma is a tumor that occurs most commonly in the parotid glands. We have experienced a rare case of acinic cell carcinoma of the left maxillary sinus. The patient was a 71-year-old female.
