Objective: To describe a case of traumatic pneumolabyrinth and subsequent hearing recovery after ejection of air with transcanal endoscopic surgical exploration.
Patients: A 38-year-old man was struck by his child while cleaning his ear with an ear pick made of bamboo, which penetrated deep into the left ear canal. Severe vertigo with vomiting and left hearing impairment ensued. In addition, high-resolution computed tomography demonstrated an air density within the vestibule.
Interventions: Exploratory tympanotomy was performed endoscopically a day after the injury and air was ejected from the oval window surgically.
Main Outcome Measures: High-resolution computed tomography, audiologic testing.
Results: Several hours after surgery, the patient's subjective vestibular symptoms lessened and 7 days after surgery, the patient felt slight dizziness when moving his head and no apparent spontaneous nystagmus was observed with an infrared charge-coupled device camera and was discharged from the hospital. Two years later, there are no subjective vestibular symptoms at all and the pure-tone average of his left ear improved to 16.7 dB.
Conclusion: We presented a case of traumatic pneumolabyrinth and the subsequent hearing recovery after ejection of air following endoscopic exploratory tympanotomy. We propose that initial management for traumatic pneumolabyrinth should be ejection of the air bubble if it is located solely in the vestibule and sparing the cochlea.

Engineered nanomaterials (ENM) are capable of crossing the placental barrier and accumulating in fetal tissue. Specifically, the ENM nano-titanium dioxide (nano-TiO), has been shown to accumulate in placental and fetal tissue, resulting in decreased birthweight in pups. Additionally, nano-TiO is an established cardiac toxicant and regulator of glucose homeostasis, and exposure in utero may lead to serious maladaptive responses in cardiac development and overall metabolism.

Doxorubicin (DOX), a chemotherapeutic agent utilized in the management of cancer, provokes cardiotoxicity although effective remedy is lacking. Given that DOX provokes oxidative stress and cell death in cardiomyocytes, this study evaluated the possible involvement of cuproptosis, a newly identified form of cell death, in DOX-instigated cardiac remodeling and contractile dysfunction, alongside the impact of the heavy metal scavenger metallothionein (MT) on DOX cardiomyopathy. Cardiac-specific MT transgenic and wild-type (WT) mice were treated with DOX (5 mg/kg/wk.

Air pollution is a major cardiovascular risk factor leading to higher rates of heart failure and myocardial infarction (MI), but its effects on functional recovery after an MI remain unknown. Cardiac rehabilitation is a cornerstone of post-MI care and leads to better performance and quality of life, but its benefits may be hampered in heavily polluted environments. To assess the effect of different pollutants on post-MI rehabilitation, we included 137 post-MI patients from 7 Spanish hospitals that were enrolled in a cardiac rehabilitation program who underwent two cardiopulmonary exercise tests (CPET) within a 12-week period.

A holder has been developed that enables electron yield-detected soft X-ray spectroscopy of fully contained samples at low temperature. Crucially, this design uses elements of the sample containment to collect ejected electrons, removing the need to expose samples directly to the vacuum environment of the spectrometer. The design is modular and should be adaptable to a number of different endstation configurations, enabling spectroscopy of air-sensitive, radioactive and vacuum-sensitive (biological) samples.
