Immunoglobulin A Antibodies Against Myelin Oligodendrocyte Glycoprotein in a Subgroup of Patients With Central Nervous System Demyelination
JAMA NEUROLOGY, v.80, n.9, p.989-995, 2023
IMPORTANCE Differential diagnosis of patients with seronegative demyelinating central nervous system (CNS) disease is challenging. In this regard, evidence suggests that immunoglobulin (Ig) A plays a role in the pathogenesis of different autoimmune diseases. Yet little is known about the presence...

Assessing Keratoconus Progression
Tzelikis, P. F.; Silva, L. N. P.; Rocha, G.. Assessing Keratoconus Progression. In: . Keratoconus: A Comprehensive Guide to Diagnosis and Treatment: SPRINGER INTERNATIONAL PUBLISHING, 2022. p.185-198.
A variety of methods have been described to both evaluate and document keratoconus progression. In a clinical practice, the ophthalmologist usually evaluates two scans of a patient performed a few months apart to estimate if there is a progression of the disease. Today, besides corneal keratometr...

Clinical Presentation and Evolution of Keratoconus
Cresta, F. B.; Orlandin, L. F.; Lucas, M. B.. Clinical Presentation and Evolution of Keratoconus. In: . Keratoconus: A Comprehensive Guide to Diagnosis and Treatment: SPRINGER INTERNATIONAL PUBLISHING, 2022. p.3-12.
Corneal ectasia is a group of disorders affecting the shape of the cornea. Keratoconus is the most common primary ectasia. It usually appears in the second decade of the life and affects both genders and all ethnicities. It is bilateral, usually asymmetric, and characterized by central or paracen...
