Suboptimal multisensory processing in pediatric migraine without aura: a comparative, cross-sectional study.

Alterations of sensory processing in migraine are well known. There is some evidence to suggest that multisensory processing is altered in migraine as well, but the area is underexplored, especially regarding pediatric migraine. A visual and an audiovisual version of the Rutgers Acquired Equivalence Test paradigm was administered to pediatric patients with migraine without aura (aged 7-17.

Visually guided associative learning in pediatric and adult migraine without aura.

Introduction: The Rutgers Acquired Equivalence Test is a visually guided equivalence learning paradigm that involves rule acquisition and generalization. Earlier we found impaired performance in this paradigm among adult migraine patients without aura. The aim of the study was to investigate if similar impairments can be found already in the pediatric form of the disease and to compare the performance of the pediatric study population with that of an adult study population.

[Maternal and neonatal vitamin B deficiency detected by expanded newborn screening].

Introduction: Infant vitamin B deficiency can manifest as a severe neurodegenerative disorder and is usually caused by maternal deficiency due to vegetarian diet or pernicious anaemia. Its early recognition and treatment can prevent potentially serious and irreversible neurologic damage. Biochemically, vitamin B deficiency leads to an accumulation of methylmalonic acid, homocysteine, and propionylcarnitine.

Marginal Zone Macrophage Receptor MARCO Is Trapped in Conduits Formed by Follicular Dendritic Cells in the Spleen.

The marginal zone (MZ) region of the spleen plays an important role in leukocyte traffic and the removal of blood-borne pathogens by resident macrophages. Macrophage receptor with a collagenous structure (MARCO), expressed by MZ macrophages, recognizes several microbial ligands and is also involved in the retention of MZ B cells. Here, we report that MARCO is also associated with follicular dendritic cells (FDCs) in the spleen.

Age-related prevalence and features of migraine headache in Hungarian schoolchildren and adolescents.

Background: Differences occur in certain features of childhood and adult migraine, such as the duration and location. However, few studies have been reported of the changes in other symptoms during childhood.

Aims: The aims of this study were to establish the prevalence of migraine headache in children in Hungary, and to investigate the changes in prevalence of migraine and migraine symptoms in a wide paediatric age range.
