Headache and Tremor: Co-occurrences and Possible Associations.

Background: Tremor and headache are two of the most prevalent neurological conditions. This review addresses possible associations between various types of tremor and headache, and provides a differential diagnosis for patients presenting with both tremor and headache.

Methods: Data were identified by searching MEDLINE in February 2015, with the terms "tremor" and terms representing the primary headache syndromes.

Interleukin-17 induces hyperresponsive interleukin-8 and interleukin-6 production to tumor necrosis factor-alpha in structural lung cells.

Lung epithelial cells contribute to local inflammation by the production of pro-inflammatory mediators like interleukin (IL)-8 and IL-6. Although their production depends on gene transcription, previous studies showed that post-transcriptional mechanisms modulate IL-8 and IL-6 production. Human lung epithelial cells turn from normoresponsive into hyperresponsive IL-8- and IL-6-producing cells when their IL-8 and IL-6 mRNA degradation is reduced.
