Bilateral Medial Medullary Infarct with Unique Radiological Presentation.

Bilateral medial medullary infarction is a rare subtype of stroke.The typical heart-shaped appearance on magnetic resonance imaging is pathognomonic for bilateral medial medullary syndrome. Vertebrobasilar dolichoectasia is a condition characterized by tortuous dilatation and marked enlargement of the basilar and vertebral arteries, and it may cause posterior circulation infarction. We present the case of a 55-year-old female patient with complaints of speech disorder, regression in consciousness, and difficulty breathing. Diffusion-weighted imaging examination was normal on arrival. In the cranial imaging after 24 hours, acute infarction was observed in the bilateral medial medullary area. Time-of-flight magnetic resonance angiography revealed vertebrobasilar dolichoectasia. In this report, a case of bilateral medial medullary infarction with a unique radiological appearance accompanied by vertebrobasilar dolichoectasia, which is rarely reported in the literature, is presented. Keywords: Stroke, infarct, bilateral medial medullary infarction, heart appearance.

Effect of COVID-19 on seizures and patient behavior in people with epilepsy.

Background and purpose:

To evaluate the long-term effects of the COVID-19 pandemic on seizure frequency and levels of mental distress in individuals with epilepsy and identify potential risk factors associated with increased seizure frequency.

This is a cross-sectional study conducted in Türkiye in May 2021 by phone. Information on epilepsy syndromes, antiseizure medications, average seizure frequency, and drug resistance was obtained from medical records. A questionnaire was completed that included demographic and clinical characteristics and Kessler Psychological Distress Scale 10 (K-10). From people with epilepsy (PWE), seizure control in the month before the pandemic and perceived stress, sleep changes, changes in adaptation during this period, and whether there were changes in seizure control after the pandemic were questioned.

A total of 227 patients were included, and the K-10 score of 81.9% (186/227) of PWE was found to be ≥30. An increase in seizure frequency was detected in 34 (15%) patients. The factors affecting the increase in seizure frequency were analyzed using logistic regression analysis. In the univariate model hesitate to go to the emergency room despite having seizures during the pandemic (OR= 8.325; 95% CI: [2.943 - 23.551], p=<0.001) was evaluated as the parameter with the highest risk of increased seizure frequency. In multivariate analyses (enter model) only polytherapy (OR= 2.945; 95% CI: [1.152 – 7.532], p=0.024) was detected as the parameter with increased seizure frequency. 

One year after the declaration of the pandemic, we found that stress was still common, the frequency of seizures increased. In multivariate analyses, only polytherapy was detected as the parameter with increased seizure frequency. 

Isolated corpus callosum lesion associated with cytokine storm in COVID-19.

Coronavirus disease 2019 (COVID-19) causes many neurological complications such as cerebrovascular diseases, encephalitis, myelitis, and demyelinated disease. Here we present a rare complication of COVID-19: an isolated cytotoxic lesion of the splenium of the corpus callosum that occurred during a cytokine storm. It responded well to tocilizumab treatment, with complete regression of the lesion.
