Emotional well-being and pain could be a greater determinant of quality of life compared to motor severity in cervical dystonia.

Non-motor symptoms (NMS) occur in patients with cervical dystonia (CD) but with variable frequencies and impact on health-related quality of life (HRQoL). To define non-motor and motor profiles and their respective impact on HRQoL in CD patients using the newly validated Dystonia Non-Motor Symptoms Questionnaire (DNMSQuest). In an observational prospective multicentre case-control study, we enrolled 61 patients with CD and 61 age- and sex-matched healthy controls (HC) comparing demographic data, motor and non-motor symptoms and HRQoL measurements.

Validation of a self-completed Dystonia Non-Motor Symptoms Questionnaire.

Objective: To develop and validate a novel 14-item self-completed questionnaire (in English and German) enquiring about the presence of non-motor symptoms (NMS) during the past month in patients with craniocervical dystonia in an international multicenter study.

Methods: The Dystonia Non-Motor Symptoms Questionnaire (DNMSQuest) covers seven domains including sleep, autonomic symptoms, fatigue, emotional well-being, stigma, activities of daily living, sensory symptoms. The feasibility and clinimetric attributes were analyzed.

Acute effect of calcium channel blockers on adriamycin exposed isolated adult cardiocytes.

When tested with isolated, calcium-resistant resting rat cardiocytes in an in vitro assay system, adriamycin exerted a dose-dependent cytotoxic effect which could easily be assessed by the ATP depletion of the heart cells and the loss of vitality as monitored by morphological changes (blebbing, spherical contraction). Apart from extremely high non pharmacological concentrations of verapamil and diltiazem, both calcium antagonists left the cardiocytes intact and without loss of internal ATP when given alone to the medium. Coincubation of adriamycin and verapamil or diltiazem did not increase adriamycin toxicity to the cardiocytes; instead a remarkable ATP preservation by verapamil could be demonstrated when both drugs (adriamycin and verapamil) were incubated simultaneously with the heart cells.
