Article Synopsis
  • The use of electrical stimulation near cochlear implants (CIs) is typically not recommended due to risks of implant damage and inner ear injury, but it is essential during surgeries for monitoring nervous system integrity.
  • A case study involving a patient with a CI who underwent two surgeries for scoliosis showed no auditory function loss or CI issues after the procedures, even with transcranial electrical stimulation used for monitoring.
  • The findings support previous reports that indicate no failures of CIs or hearing deterioration from such stimulation, highlighting an urgent need for a reevaluation of current contraindications and a thorough risk analysis by manufacturers and regulatory bodies.

Article Synopsis
  • The study investigates factors impacting the treatment and outcomes of iatrogenic cervical oesophageal and hypopharyngeal perforations (iCEHPs) by analyzing data from 24 patients treated from 2004 to 2021.
  • It was found that surgical neck exploration was the most common treatment, especially for uncontained perforations, and patients managed surgically typically had higher C-reactive protein (CRP) levels.
  • Key findings highlighted that delayed diagnosis increases mortality risk, and a history of neck irradiation significantly worsens patient prognosis.

The evolution of circulating viruses is shaped by their need to evade antibody response, which mainly targets the viral spike. Because of the high density of spikes on the viral surface, not all antigenic sites are targeted equally by antibodies. We offer here a geometry-based approach to predict and rank the probability of surface residues of SARS spike (S protein) and influenza H1N1 spike (hemagglutinin) to acquire antibody-escaping mutations utilizing in-silico models of viral structure.

Background: Cervical spinal surgery is considered safe and effective. One of the few specific complications of this procedure is C5 nerve root palsy. Expressed primarily by deltoid muscle and biceps brachii weakness, it is rare and has been related to nerve root traction or to ischemic spinal cord damage.

Article Synopsis
  • A real-time method for detecting pedicle wall breaches during spinal deformity surgeries was tested on 56 patients, comparing the effectiveness of a continuous stimulation technique to manual inspection.
  • Results showed that using a 9 mA stimulation threshold had a high sensitivity (88%) and specificity (89.5%) for predicting breaches, indicating it could reliably alert surgeons during procedures.
  • The study found that medial breaches had lower stimulation thresholds than lateral ones, and the technique outperformed traditional methods in identifying potential problems, enhancing surgical safety.
