Abstract: Fluctuations of mood and psychic activation were assessed in relation to "mobile" and "immobile" periods in 18 patients with Parkinson's disease presenting typical "end-of-dose deterioration". Twelve subjects with chronic but active rheumatoid arthritis presenting increased physical disability due to severe morning joint stiffness with a repetitive pattern of mobile and immobile periods acted as controls. The overall degree of disability and its fluctuations were close enough in the two groups for fair comparison of changes in affective behaviour. Temporary immobility was accompanied by adverse changes of mood and activation, which were significantly more marked in the Parkinson's disease group than in the controls, though to a lesser extent in those Parkinson's disease patients rated depressed even in their mobile periods. The possible correlation between mood changes and fluctuations of central dopaminergic function in the Parkinson's disease patients is discussed.
Which is the apt title for the abstract? option1: Mood changes associated with "end-of-dose deterioration" in Parkinson's disease: a controlled study. option2: Peripheral neuropathy in systemic vasculitis: clinical and electrophysiologic study of 22 patients.
answer:
Mood changes associated with "end-of-dose deterioration" in Parkinson's disease: a controlled study.

question:
Abstract: In two typical cases of calcaneal fracture dislocation, the primary fracture, which runs forward and medially from a point behind the sustentaculum tali, is associated with inversion of the hindfoot. The calcaneus splits into a small anteromedial and a larger posterolateral fragment. Rupture of the lateral collateral ligament allows the posterolateral calcaneal fragment to move laterally to lie immediately subjacent to the distal fibula. Closed reduction is impossible. Open reduction of this rare fracture dislocation is essential. A lateral approach to the calcaneus is generally sufficient, but a second medial incision may be required.
Which is the apt title for the abstract? option1: Fracture dislocation of the calcaneus. A report of two cases. option2: Safety and immunogenicity of live attenuated rhesus monkey rotavirus vaccine.
answer:
Fracture dislocation of the calcaneus. A report of two cases.

question:

answer:
Dietary habits in patients with dumping syndrome-like symptoms after proximal selective vagotomy.
