Evaluation of Semicircular Canal Function Using Video Head Impulse Test in Patients With Peripheral Vestibular Disorders Without Nystagmus.

Objectives This study aims to evaluate semicircular canal function using video head impulse test (vHIT) in patients with peripheral vestibular disorders without nystagmus. Methods Patients who underwent vHIT were enrolled in this study, and the proportion of abnormal findings on vHIT in patients without nystagmus was investigated. In addition, the results of vestibular testing were investigated in cases in which both vHIT and caloric testing were performed in patients without nystagmus.

A study on formalizing the knowledge of data curation activities across different fields.

In recent years, with the trend of open science, there have been many efforts to share research data on the internet. To promote research data sharing, data curation is essential to make the data interpretable and reusable. In research fields such as life sciences, earth sciences, and social sciences, tasks and procedures have been already developed to implement efficient data curation to meet the needs and customs of individual research fields.

Medical care provision at the venue of the weightlifting event of the Tokyo 2020 Olympic Games.

Purpose: This study aimed to investigate the medical care provided at the venue of the weightlifting event of the Tokyo 2020 Olympic Games.

Methods: We retrospectively evaluated athletes who availed of medical services at the venue during the weightlifting event of the Tokyo 2020 Olympic Games. In total, 194 athletes participated in the weightlifting competition.

Nickel-catalyzed thioallylation of alkynes with allyl phenyl sulfides.

Allylic sulfides add to alkynes in the presence of nickel complexes efficiently to afford thio-1,4-dienes regio- and stereoselectively. Functional groups such as alkoxy, siloxy, hydroxy, carboalkoxy, chloro, and cyano groups are tolerated. A mechanism that involves a pi-allyl nickel intermediate is proposed on the basis of isolation of pi-allyl complexes and distribution of products in the reactions of alpha- or gamma-methylated allyl sulfide.

[A case of gastric cancer initially presented by bilateral chylothorax].

The patient, a 66-year-old woman, visited our hospital with chief complaints of nocturnal coughing and dyspnea. Chest radiography revealed bilateral pleural effusion, and she was admitted to our hospital to undergo more thorough examination. The bilateral pleural effusion was identified as chyle.

Reactions of a carbamoylstannane with acid chlorides: highly efficient synthesis of alpha-oxo amides.

Treatment of acid chlorides with a carbamoylstannane under mild conditions (mostly rt for a few hours) affords alpha-oxo amides in high yields. Vicinal polycarbonyl compounds are also obtained, although spontaneous decarbonylation occasionally occurs.

A surgical treatment for unstable osteochondritis dissecans lesions of the humeral capitellum in adolescent baseball players.

Background: Various methods of surgical treatment for unstable osteochondritis dissecans lesions of the humeral capitellum have shown the potential to lead to osteoarthritis and poor functional results in throwing activities.

Purpose: The purpose of this study was to evaluate the results of surgical treatment with pull-out wiring and bone grafting (as established by Kondo in 1989) in patients with unstable osteochondritis dissecans lesions of the humeral capitellum.

Study Design: Retrospective review.
