Increase in internetwork functional connectivity in the human brain with attention capture.

Attention is often extolled for its selective neural properties. Yet, when powerfully captured by a salient unexpected event, attention can give rise to a broad cascade of systemic effects for evaluating and adaptively responding to the event. Using graph theory analysis combined with fMRI, we show here that the extensive psychophysiological and cognitive changes associated with such attention capture are related to large-scale distributed changes in the brain's functional connectivity.

Myths and Facts about Vitiligo: An Epidemiological Study.

Vitiligo is a pigmentary disorder associated with many disease conditions that necessitates multiple drug regimens, which make the treatment complicated. This stigmatic disease forces the patient to approach all system of medicines as well as alternative medicines of non proven value, which further worsens the situation. At the same time the nonadherence to the treatment reflects poor prognosis, which is misunderstood for lack of response resulting in poor faith to the medications.
