Published: July 2016

Background: Acute subdural hematoma (ASDH) is the most important cause of severe head injuries occurring during judo practice in Japan. Repeated head injuries have been reported as a cause of fatal ASDH, although the mechanism remains unknown.

Case Description: A 16-year-old boy visited an emergency department with vomiting 3 days after a strong blow to the occipital region during judo practice. Although computed tomography was performed at that time, a small interhemispheric ASDH was overlooked. The patient sustained another head injury 19 days after the first, which led to convulsions and disturbance of consciousness. The ASDH was increased in size on computed tomography. We performed a surgical evacuation, which revealed tearing of a bridging vein, after which the patient showed a good recovery.

Conclusions: It is important to be aware of the possibility of a small ASDH in concussed judo players after an initial impact, which may lead to subsequent fatal ASDH after another impact incident.

Background: Noninvasive mechanical ventilation (NIMV), when in synchronized intermittent mandatory ventilation, continuous positive airway pressure, or patient-triggered ventilation modes, is known to be a cause of facial, nasal, head, and skin pressure injuries in preterm infants.

Objective: The objective of this study is to examine the efficacy of using a checklist with preterm infants under nasal NIMV in preventing facial, nasal, and head pressure injuries.

Method: The study was conducted quasi-experimentally on preterm infants under NIMV.

Case: We present a 79-year-old woman with a complex elbow fracture including a comminuted proximal ulna fracture, coronoid process fracture, and comminuted radial head fracture treated with primary total elbow arthroplasty (TEA). The patient completed an early therapy protocol and had complete healing. At 15 months postoperatively, she had full pronosupination and elbow arc of motion from 10 to 135° with no reported pain.

Examining the risk of delirium in patients hospitalized with COVID-19: Insights from the homeless population.

PLoS One

January 2025

Department of Diagnostic and Health Sciences, College of Health Professions, University of Tennessee Health Science Center, Memphis, TN, United States of America.

For patients hospitalized with COVID-19, delirium is a serious and under-recognized complication, and people experiencing homelessness (PEH) may be at greater risk. This retrospective cohort study compared delirium-associated risk factors and clinical outcomes between PEH and non-PEH. This study used patient records from 154 hospitals discharged from 2020-2021 from the Texas Inpatient Public Use Data file.

Electric field stimulation directs target-specific axon regeneration and partial restoration of vision after optic nerve crush injury.

PLoS One

January 2025

Department of Ophthalmology, Keck School of Medicine, USC Roski Eye Institute, University of Southern California, Los Angeles, California, United States of America.

Failure of central nervous system (CNS) axons to regenerate after injury results in permanent disability. Several molecular neuro-protective and neuro-regenerative strategies have been proposed as potential treatments but do not provide the directional cues needed to direct target-specific axon regeneration. Here, we demonstrate that applying an external guidance cue in the form of electric field stimulation to adult rats after optic nerve crush injury was effective at directing long-distance, target-specific retinal ganglion cell (RGC) axon regeneration to native targets in the diencephalon.

Purpose: Corneal alkali burns are severe ocular injuries characterized by intense inflammation, tissue damage, and vision impairment, with current treatments often insufficient in restoring corneal function and clarity. This study aimed to evaluate the therapeutic effects of recombinant thrombomodulin domain 1 (rTMD1) in the treatment of corneal alkali burns, focusing on its impact on inflammation, tissue repair, fibrosis, and neovascularization.

Methods: A murine model of corneal alkali burn was utilized to investigate the therapeutic potential of rTMD1.
