Hematological and immunological effects of stress of air traffic controllers in northeastern Brazil.

Methods: Thirty air traffic controllers and 15 aeronautical information service operators were evaluated.

Headache precipitated by Valsalva maneuvers in patients with congenital Chiari I malformation.

Neuroendocrine dysfunction in fibromyalgia and migraine.

Fibromyalgia (FM) and migraine are common chronic disorders that predominantly affect women. The prevalence of headache in patients with FM is high (35%-88%), with migraine being the most frequent type. A particular subgroup of patients with FM (approximately half) presents with a combined clinical form of these two painful disorders, which may exhibit a different manner of progression regarding symptomatology and impact on daily activities.

Post-traumatic headache.

Neonatal administration of fluoxetine did not alter the anxiety indicators, but decreased the locomotor activity in adult rats in the elevated plus-maze.

The objective of this study was evaluate the anxiety and locomotor activity (LA) in 52 Wistar adult male rats, being 26 treated with fluoxetine (10 mg/Kg - sc) in the neonatal period. These same rats received foot shock (FS) (1.6-mA - 2-s) in the 90th day.
