Visualize and quantify the structural alteration of the rat spinal cord injury based on multiphoton microscopy

Abstract

The development of imaging technique to visualize and quantify the structural alteration of the spinal cord injury (SCI) may lead to better understanding and treatments of the injuries. In this work, multiphoton microscopy (MPM) based on two-photon excited fluorescence (TPEF) and second-harmonic generation (SHG) was tentatively applied to quantitatively visualize the cellular microstructures of SCI to demonstrate the feasibility and superiority of MPM in SCI imaging. High-contrast MPM images of normal and injured spinal cord tissue were obtained for comparison. Moreover, the changes of injured spinal cord were characterized by the quantitative analysis of the MPM images. These results showed that MPM combined with quantitative method has the ability to identify the characteristics of spinal cord injury including the changes in the contents of nerve fibers and extracellular matrix. With the advancement of MPM, we believe that this technique has great potential to provide the histological diagnosis for the monitoring and evaluation of SCI.

Relationship of age to foramen of Huschke and investigation of the development of spontaneous temporomandibular joint herniation

The aim of this study was to determine the prevalence, localization, and width of the foramen of Huschke (FH) and the relationship between age and FH. Another aim was to investigate the development of spontaneous temporomandibular joint (TMJ) herniation. This was a retrospective review of high-resolution computed tomography images of the temporal bone of 1025 patients. The prevalence of FH and the axial and sagittal diameters of the foramen were evaluated. Cases were found in which the TMJ had herniated through FH into the EAC.

Management of osteoradionecrosis of the jaws with pentoxifylline–tocopherol: a systematic review of the literature and meta-analysis

Osteoradionecrosis (ORN) of the jaws remains among the most commonly encountered and challenging complications of radiotherapy to the head and neck. The purpose of this study was to provide a review of the medical management for ORN and evaluate the reported outcomes with the use of pentoxifylline and tocopherol (PENTO), by means of a systematic review and meta-analysis. The predictor variable was the use of PENTO in the treatment of ORN. The outcome variable was the proportion of full recovery or significant improvement not requiring further intervention.

Endoscopic laryngo-pharyngeal surgery for elderly patients

Due to the rising number of elderly patients and advances in endoscopic devices, early laryngeal and pharyngeal cancers are increasingly found in elderly patients. In these cases, minimally invasive endoscopic larygo-pharyngeal surgery (ELPS) may be indicated. However, the safety and efficacy of ELPS in elderly populations has not been established. The purpose of this study was to investigate the safety, outcomes and feasibility of ELPS in very elderly patients.

Endolymphatic hydrops severity in magnetic resonance imaging evidences disparate vestibular test results

It has been suggested that in Ménière's disease (MD) a dissociated result in the caloric test (abnormal result) and video head-impulse test (normal result) probably indicates that hydrops affects the membranous labyrinth in the horizontal semicircular canal (HSC). The hypothesis in this study is that based on endolymphatic hydrops' cochleocentric progression, hydrops should also be more severe in the vestibule of these patients than in those for whom both tests are normal.
