Article Synopsis
- A 65-year-old man with a past condition of Wallenberg syndrome was admitted for nausea, vertigo, facial numbness, and right side paralysis after experiencing neurological symptoms.
- MRI showed no immediate signs of stroke, but MRA indicated a complete blockage of the right vertebral artery, leading to a suspicion of atypical lateral medullary infarction.
- After administering IV-tPA, the man showed significant improvement, and further imaging confirmed Opalski syndrome, highlighting the need for awareness of this syndrome in similar patient presentations and considering stroke treatment even without classic symptoms.
Article Synopsis
- - Subacute combined degeneration of the spinal cord (SCDS) is a neurodegenerative condition linked to vitamin B deficiency, often presenting with issues like weakness, numbness, and gait problems.
- - A case study of a 45-year-old woman highlighted symptoms like worsening lower limb weakness and specific lab results, showing macrocytosis but no anemia or elevated methylmalonic acid (MMA) and homocysteine (Hcy) levels, with no abnormalities in spinal cord MRI.
- - Improvement in her symptoms and lab results after vitamin B supplementation confirmed the diagnosis of SCDS, indicating the importance of monitoring MMA levels and neurological symptoms for accurate diagnosis.
Background: Rheumatoid meningitis presenting with a stroke-like attack (RMSA) is a rare manifestation of rheumatoid arthritis (RA). When the patients arrive within the time-window for recombinant tissue plasminogen activator (rt-PA) infusion therapy, no diagnostic protocol has been established.
Case Presentation: A 55-year-old woman was brought by ambulance to our hospital with complaints of sudden-onset dysarthria and left arm numbness.
Background: Difficulty turning over in bed is a common night-time symptom in Parkinson's disease (PD). We aimed to quantitatively evaluate overnight turnover movements using a three-axis accelerometer and to investigate whether inability to turn in bed is related to daytime sleepiness, sleep quality, and depressive mood in PD patients.
Methods: We examined 64 patients with PD (mean age, 73.
Contrast-enhanced transoral carotid ultrasonography (CETOCU) is a novel modality for imaging the distal extracranial internal carotid artery, which is not possible with conventional carotid ultrasonography. We present a representative case that demonstrates the usefulness of CETOCU.

However, to the best of our knowledge, this is the 1st report regarding improvement of ME without discontinuation of fingolimod administration.
Case Presentation: The patient was a 66-year-old woman with relapsing-remitting multiple sclerosis.
