Its management can be difficult. We present here an overview of the current guidelines for the management of chronic cough. Different steps are detailed, including the initial research of an obvious etiology and alert signs that should lead to further investigation of underlying condition. The diagnosis of the most frequent causes: asthma, non-asthmatic eosinophilic bronchitis, gastroesophageal reflux disease and upper airway cough syndrome should be considered, assessed and treated accordingly. Recent advances have been made in the comprehension of refractory chronic cough pathophysiology as well as its pharmacologic and non-pharmacologic treatment, especially speech pathology therapy. Keywords: asthma, gastroesophageal reflux, upper airway cough syndrome, chronic hypersensitivity syndrome, refractory chronic cough, speech pathology therap

No full textInternational audienceThe relation between lattice deformation, dc electrical properties and 1/f noise at room temperature was investigated experimentally in two series of high epitaxial La0.7Sr0.3MnO3 (LSMO) thin films of various thicknesses. The first series was deposited on SrTiO3 (0 0 1) single crystal substrates by pulsed laser deposition and the second one on SrTiO3-buffered Si (0 0 1) substrates by reactive-molecular-beam epitaxy. A clear correlation was found between 1/f noise level and the temperature of the metal-to-insulator transition. These findings are important in view of the optimization of LSMO thin films for applications in sensors
