Intraoperative sensitization in trigeminal region caused by postherpetic neuralgia: a case report.

J Med Case Rep

January 2025

Department of Pain, The Third Xiangya Hospital and Institute of Pain Medicine, Central South University, Changsha, China.

Background: Interventional therapy of trigeminal neuropathic pain has been well documented; however, intraoperative monitoring and management of pain hypersensitivity remains barely reported, which may pose a great challenge for pain physicians as well as anesthesiologists.

Case Presentation: A 77-year-old Han Chinese male, who suffered from severe craniofacial postherpetic neuralgia, underwent pulsed radiofrequency of trigeminal ganglion in the authors' department twice. The authors successfully placed a radiofrequency needle through the foramen ovale during the first procedure with local anesthesia and intravenous sedation (dexmedetomidine).

Background: Our aim was to develop a quantitative model for immediately estimating the risk of death and/or brain injury in late-onset sepsis (LOS) in preterm infants, based on objective and measurable data available at the time sepsis is first suspected (i.e., time of blood culture collection).

Many theories of time perception propose the existence of an internal pacemaker, and studies across behavioral, physiological, and neuroscience fields have explored this concept. Specifically, Spontaneous Motor Tempo (SMT), the most comfortable and natural tapping tempo for each individual, is thought to reflect this internal pacemaker's tempo. Changes in heart rate are also linked to time estimation, while Individual Alpha Frequency (IAF), the peak in the alpha range (8-13 Hz) observed in EEG, is reported to reflect the brain's temporal processing.

The intra-aortic balloon pump (IABP) is a widely-used mechanical circulatory support device that enhances hemodynamics in patients with heart conditions. Although the IABP is a common clinical tool, its effectiveness in enhancing outcomes for patients with acute myocardial infarction and cardiogenic shock remains disputed. This study aimed to assess the effectiveness of intra-aortic dual-balloon pump (IADBP) and its impact on aortic hemodynamics compared with an IABP.

Early neurological deterioration (END) following endovascular treatment (EVT) in acute ischemic stroke (AIS) patients is associated with poor long-term outcomes. Although unstable systolic blood pressure (SBP) after EVT is recognized as a risk factor for END, it remains unclear whether this association persists after excluding identifiable causes of END. In this prospective, observational cohort study, AIS patients who underwent EVT within 24 h of stroke onset were included.
