Article Synopsis
- The concept of concussion as solely a reversible injury is outdated; it may cause lasting structural changes in the brain and should be addressed as synonymous with mild traumatic brain injury (mTBI).
- Forensic physicians focus on diagnosing mTBI, its severity, and understanding how the injury occurred, often consulting neurologists for clarity on the diagnosis.
- Research indicates that the average recovery period for mTBI in people aged 20-65 is now about 39 days, with recovery time increasing with age, and post-concussion syndrome is a common complication.
Article Synopsis
- This study explored the changes in the H-reflex recruitment curve in patients with unilateral S1 radiculopathy, comparing symptomatic and asymptomatic limbs.
- Twenty-four volunteers with confirmed nerve root compression participated, with findings indicating that while M-wave threshold intensity was similar in both limbs, the symptomatic limb showed a trend toward increased threshold for the H-reflex.
- Key results included a significant decrease in the slope of the H-reflex and differences in Hmax/Mmax ratios between limbs, highlighting the potential for these parameters to enhance diagnosis and clinical assessments of lumbosacral radiculopathy.
Introduction: Non-contrast computed tomography (CT) and CT angiography are the gold standard in neuroimaging diagnostics in the case of suspected stroke. CT perfusion (CTP) may play an important role in the diagnosis of stroke mimics (SM), but currently, it is not a standard part of the stroke diagnostic procedure. The project is a multicentre prospective observational clinical research focused on refining the diagnostics of stroke and stroke mimics (SM) in hospital care.

We aimed to evaluate the safety and outcomes of revascularization treatments in patients with AIS and COVID-19.
Methods: This was a retrospective multicenter cohort study of consecutive patients with AIS receiving intravenous thrombolysis (IVT) and/or endovascular treatment (EVT) between March 2020 and June 2021 tested for severe acute respiratory syndrome coronavirus 2 infection.
Background The benefit of intravenous thrombolysis is time dependent. It remains unclear, however, whether dramatic shortening of door-to-needle time (DNT) among different types of hospitals nationwide does not compromise safety and still improves outcome. Methods and Results Multifaceted intervention to shorten DNT was introduced at a national level, and prospectively collected data from a registry between 2004 and 2019 were analyzed.
