Article Synopsis
  • - The article discusses a rare finding of atypical pathological features in the brains of patients with drug-resistant epilepsy, revealing a mix of ganglioglioma and focal cortical dysplasia, which hasn't been documented before.
  • - Comprehensive tests including histopathological staining and molecular genetic analysis were conducted, and MRI scans showed unusual patterns such as "transmantle" distribution and local alterations in the brain structure.
  • - The findings suggest the presence of a new subgroup of gangliogliomas characterized by cellular atypia, indicating a potential link between different types of neuronal-glial tumors that could reshape our understanding of epilepsy-related brain pathology.

The variants of heterotypic comorbidity of anxiety disorders (AD) with attention deficit hyperactivity disorder, autism spectrum disorders, speech and language development disorders, specific learning disabilities (dyslexia, dysgraphia, dyscalculia), migraine, tension type headache in children and adolescents are discussed. In cases of heterotypic comorbidity the patients with AD referrals to specialists may be primarily associated with their emotional problems. Meanwhile, the comorbidity of AD with these diseases leads to a deterioration of their clinical manifestations and a worsening of the prognosis, and anxiety symptoms often not only persist, but also increase with age.

Objective: To evaluate the diagnostic capabilities of modifying the standard MRI protocol as part of an interdisciplinary presurgical examination of patients with epileptogenic substrates of unknown etiology.

Material And Methods: The results of dynamic MRI of 8 patients with a referral diagnosis of focal cortical dysplasia (FCD) were analyzed. In 7 patients, epilepsy was the reason for a standard MRI of the brain; in another patient with myasthenia, MRI was performed as part of a comprehensive examination.

N-Hexane is a solvent widely used in manufacturing as a cleaner, degreaser and component of rubber cement. Chronic exposure to -hexane either through contact with unprotected skin or inhalation can lead to the development of clinical symptoms and electrophysiological changes similar to those of inflammatory demyelinating polyneuropathy which requires careful differential diagnosis. This article presents three cases of severe predominantly motor polyneuropathy with demyelinating features in 15- and 16-year-old adolescents.
