Summary
Susac's syndrome is a rare neurological condition. This case study details a challenging management of a patient with Susac's syndrome, requiring a multi-drug approach for remission.
Area of Science:
- Neurology
- Immunology
Background:
- Susac's syndrome is a rare autoimmune condition affecting the brain, retina, and inner ear.
- It can present with diverse neurological symptoms, including headaches, visual disturbances, and cognitive impairment.
Purpose of the Study:
- To report a challenging case of Susac's syndrome in a 39-year-old woman.
- To illustrate the complex management and treatment strategies required for achieving remission.
Main Methods:
- Diagnosis of Susac's syndrome after excluding other potential causes.
- Treatment involved a combination of corticosteroids, rituximab, cyclophosphamide, and intravenous immunoglobulin (Ig).
Main Results:
- The patient experienced worsening symptoms despite initial treatment with intravenous methylprednisolone.
- Remission was achieved after 4 months of aggressive immunosuppressive therapy.
- Long-term maintenance therapy includes aspirin, intravenous Ig, and mycophenolate mofetil.
Conclusions:
- Susac's syndrome requires a multi-faceted treatment approach for effective management.
- Aggressive immunosuppression is crucial for achieving and maintaining remission in complex cases.
- Ongoing monitoring and potential for relapse necessitate long-term therapeutic strategies.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

182
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
