Striatal dysfunction plays an important role in dystonia, but the striatal cell types that contribute to abnormal movements are poorly defined. We demonstrate that conditional deletion of the DYT1 dystonia protein torsinA in embryonic progenitors of forebrain cholinergic and GABAergic neurons causes dystonic-like twisting movements that emerge during juvenile CNS maturation. The onset of these ...
OBJECTIVE To describe the development and initial psychometric evaluation of a measure of social functioning in children and adolescents with chronic medical conditions, Living with a Chronic Illness (LCI), designed to distinguish social difficulties related to the illness from those social difficulties associated with other factors (e.g., limited income). METHODS Parents (n = 108) and youths...
BACKGROUND A large body of evidence has now accumulated describing the advantages of multiple breath washout tests over conventional spirometry in cystic fibrosis (CF). Although the majority of studies have used exogenous sulphur hexafluoride (SF6) as the tracer gas this has also led to an increased interest in nitrogen washout tests, despite the differences between these methods. The impact of...
BACKGROUND The lung clearance index (LCI), measured by multiple breath washout (MBW), reflects global ventilation inhomogeneity and is a sensitive marker of early cystic fibrosis (CF) lung disease. Current evidence is based on a customized mass spectrometry system that uses sulfur hexafluoride (SF6) as a tracer gas, which is not widely available. Nitrogen (N2) washout may be better suited for c...
Background Multiple breath washout (MBW) using sulfur hexafluoride (SF 6 ) has the potential to reveal ventilation heterogeneity which is frequent in patients with obstructive lung disease and associated small airway dysfunction. However, reference data are scarce for this technique mostly restricted younger cohorts. We therefore set out evaluate influence of anthropometric parameters on SF -MB...
A 51-year-old active smoker with primary acquired pulmonary alveolar proteinosis (PAP) diagnosed by biopsy and anti-GM-CSF antibodies was treated safely with whole-lung lavage (WLL). This resulted in a rapid improvement of symptoms and arterial blood oxygenation, but not of standard lung function parameters. However, we also performed the multiple-breath nitrogen washout (MBW) test to determine...
We (Innovision ApS, Odense, Denmark) are the manufacturer of the AMIS 2000 medical mass spectrometer system that, using user-specific software and hardware, was adapted to perform MBW. The AMIS 2000-based devices are now considered the ‘‘gold standard’’ device for SF6 LCI measurements in cystic fibrosis patients by opinion leaders in the field [2]. This device has been used in the vast majority...
