Tumefactive demyelination: Clinical outcomes, lesion evolution and treatments
Staley A Brod1, J William Lindsey1, Flavia Nelson1
1Department of Neurology, University of Texas, USA.
Summary
Tumefactive demyelination, often mistaken for tumors, typically follows a benign course in multiple sclerosis patients. Lesion regression, associated with treatment, correlates with improved outcomes and disability status.
Area of Science:
- Neuroimmunology
- Neurology
- Radiology
Background:
- Tumefactive demyelination presents as large lesions mimicking tumors, raising concerns for malignancy.
- Accurate diagnosis is crucial to avoid misinterpretation and guide appropriate management.
Purpose of the Study:
- To investigate the clinical outcomes and lesion evolution in patients with tumefactive demyelination.
- To assess the relationship between therapies and clinical outcomes in this patient cohort.
Main Methods:
- Retrospective review of 28 multiple sclerosis patients with tumefactive demyelination over 10 years.
- Analysis of clinical outcomes, lesion progression/regression on MRI, and treatment responses.
Main Results:
- No increase in Extended Disability Status Scale (EDSS) was observed across the cohort.
- Lesion regression was linked to improved EDSS and correlated with the use of therapy.
- Absence of MRI enhancement predicted lesion regression, while specific therapies or corticosteroid infusions did not show long-term EDSS improvement.
Conclusions:
- Tumefactive demyelination may indicate a more favorable prognosis compared to malignant lesions.
- These lesions are responsive to conventional immunomodulatory treatments, supporting a benign clinical course.

02:55The Evidence for Evolution
47.7K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

01:54Convergent Evolution
31.5K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

01:24Eukaryotic Evolution
40.3K
The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.

3.8K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
