Dyskinesia (abnormal involuntary movements) is a common complication of l-DOPA pharmacotherapy in Parkinson's disease, and is thought to depend on abnormal cell signaling in the basal ganglia. Dopamine (DA) denervated mice can exhibit behavioral and cellular signs of dyskinesia when they are treated with l-DOPA, but the clinical relevance of this animal(More)
BACKGROUND Chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and asthma are strongly associated, and patients suffering from both diseases are often difficult to treat. However, no guidelines about the management of patients with CRS and coexisting asthma exist. OBJECTIVE The purpose of this systematic review was to evaluate the management of CRSwNP(More)
BACKGROUND It has been established that patients with chronic rhinosinusitis with nasal polyps (CRSwNP) often have co-existing asthma. OBJECTIVE We aimed to test two hypotheses: (i) upper and lower airway inflammation in CRSwNP is uniform in agreement with the united airways concept; and (ii) bronchial inflammation exists in all CRSwNP patients(More)
BACKGROUND The cause of nonallergic rhinitis (NAR) and its relation to lower airway disease remains unclear. The purpose of this study was to perform a descriptive analysis of the occurrence of rhinitis in a Danish general population with focus on NAR and its association with smoking and lower airway disease. METHODS A population-based, cross-sectional(More)
In recent decades, there has been a worldwide increase in the prevalence of atopic diseases. The aim of this study was to investigate whether there has been a change in the prevalence of rhinitis among children in Denmark from 1986 to 2001. We compared data from two random population-based samples of Danish children, aged 7-17 yr, who were examined in 1986(More)
In patients with myotonic dystrophy type 1 overweight and obesity are frequent. When present this has further negative effects on the patients' pulmonary and muscle function as well as social participation. Anesthesia in myotonic dystrophy type 1 patients is associated with increased risks, especially in those who are obese. We describe the outcome of the(More)
BACKGROUND Chronic rhinosinusitis (CRS) is a common health problem that is subclassified as CRS with nasal polyps (CRSwNPs) or CRS without NPs (CRSsNP). In accordance with the united airways concept, CRSwNPs frequently coexists with asthma but to date, this association remains unexplained and its strength is uncertain. Here, we aimed to examine the(More)
In this review, we demonstrate that patients with chronic obstructive pulmonary disease (COPD) frequently report sinonasal symptoms. Furthermore, we present evidence that smoking on its own can cause nasal disease and that, in COPD patients, nasal inflammation mimics that of the bronchi. All this evidence suggests that COPD-related sinonasal disease does(More)
