Infectious causes of Alice in Wonderland syndrome.

Alice-in-Wonderland syndrome (AIWS) is a perceptual disorder embracing a spectrum of self-experienced paroxysmal body image illusions including most commonly distortions of shape (metamorphopsia), size (macropsia or micropsia), distance (pelopsia or teleopsia), movement, and color among other visual and somesthetic distortions. Depersonalization, derealization, and auditory hallucinations have also been described. Recent reports suggest that infectious diseases are the predominant etiology for AIWS, especially among children.

Alice in Wonderland syndrome: a novel neurological presentation of Zika virus infection.

Zika virus (ZIKV) is a flavivirus endemic in Africa and Southern Asian countries, which has recently emerged in unprecedented epidemic proportions around the world. Although ZIKV infection is often asymptomatic or distinguished by non-specific influenza-like symptoms, an increase in its pathogenicity and biological behavior has been the hallmark of the current pandemic. Increasing evidence suggests that neurotropic strains of ZIKV have evolved from less pathogenic strains of the virus.

A new strategy to obtain robust markers for blood vessels segmentation by using the watersheds method.

The watersheds method is a powerful segmentation tool developed in mathematical morphology. In order to prevent its over-segmentation, in this paper, we present a new strategy to obtain robust markers for segmentation of blood vessels from malignant tumors. For this purpose, we introduced a new algorithm.
