Unlabelled: The purpose of this chapter is to provide a basic instructional reference for upper extremity splint application in the context of pediatric orthopaedic trauma. In addition to reviewing the steps necessary for successful splint application, this chapter will also discuss common pitfalls to avoid in order to optimize outcomes and prevent complications during and after splint immobilization for upper extremity injuries. Embedded throughout the chapter are figures and videos that highlight how to apply various splints to the upper extremity based on the injury location and the immobilization required for different clinical situations.

Liquid organic hydrogen carriers (LOHCs) offer an attractive strategy for efficient hydrogen storage and release, thereby facilitating the effective use of hydrogen as a carbon-neutral energy carrier. The advancement of LOHC technology is highly dependent on the innovation of the catalysts. Herein, based on a strategy combining rigidity and flexibility in a single molecular catalyst, a novel class of PNP-pincer ligands, called long-short-arm acridine ligands, and their Ru complexes have been developed and successfully used in the LOHC system based on ethylene glycol (EG).

Background And Purpose: Atypical posterior canal (pc) benign paroxysmal positional vertigo (BPPV) may be caused by cupulolithiasis (cu), short arm canalithiasis (ca), or jam. The purpose of this study was to describe the clinical presentation and differential diagnosis of pc-BPPV-cu and short arm canalithiasis.

Methods: This retrospective observation study identified persons with atypical pc-BPPV based on history and findings from four positional tests.

Background: Atypical posterior canal (PC) positional nystagmus may be due to the changes in cupular response dynamics from cupulolithiasis (cu), canalithiasis of the short arm (ca-sa), or a partial/complete obstruction-jam. Factors that change the dynamics are the position of the head in the pitch plane, individual variability in the location of the PC attachment to the utricle and the position of the cupula within the ampulla, and the location of debris within the short arm and on the cupula. The clinical presentation of PC-BPPV-cu is DBN with torsion towards the contralateral side in the DH positions and SHHP or no nystagmus in the ipsilateral DH position and no nystagmus upon return to sitting from each position.
