Intraocular pressure (IOP) is crucial to the well-being of eyes. During anesthesia, the administration of succinylcholine and endotracheal intubation are associated with an increase in IOP, which may be attenuated by short-acting opioids. However, the drug of choice among the commonly used short-acting opioids is unclear.

Acute low-tone hearing loss (ALHL) is a common clinical disease and was first proposed by Abe in 1981 as sensorineural hearing loss confined to low frequencies. The best strategy for initiating medication is still unclear, as the superiority of steroids and diuretics is still debated, and combination therapy might yield additional benefits. However, no study regarding combination therapy has been published.

Article Synopsis
  • Hearing loss is prevalent and can lead to serious issues like dementia and depression, but conventional hearing aids can be hard to access or too expensive, leading to interest in personal sound amplification products (PSAPs) as a more accessible alternative.
  • A systematic review analyzed data from relevant studies to compare the effectiveness of PSAPs and conventional hearing aids for improving hearing, specifically looking at parameters like speech intelligence.
  • The analysis included five studies with 124 patients, finding no significant differences in outcomes between PSAPs and hearing aids for speech intelligence, sound quality, or listening effort, even after adjusting for varying severities of hearing loss.

Cleft palate is the most common congenital facial deformity and may result in multiple sequelae and disabilities. One common comorbidity is refractory otitis media with effusion (OME), as patients with cleft palate have impaired eustachian tube function with alteration of the nearby muscular structures. Ventilation tube insertion (VTI) is regarded as an effective mean to address OME in addition to palatal repair surgery.

  • The shock index (SI) is a tool used to predict injury severity and mortality in trauma patients, but pediatric patients have different physiological responses that may mask shock within normal vital sign ranges.
  • The study evaluated 1,265 pediatric trauma patients over a 10-year period, finding that the pediatric age-adjusted shock index (SIPA) is a more accurate predictor of mortality and injury severity compared to the standard SI.
  • While both SI and SIPA can help identify shock and predict severe traumatic injuries, they were not significant indicators for ICU admission or the need for surgery in this pediatric population.
