Chronic cough is a common symptom that can be a daunting challenge for clinicians since treatment of the underlying cause does not always provide adequate relief, an obvious cause can remain elusive, and current antitussives have fairly poor efficacy and undesirable side-effects. Patients with chronic cough typically describe a range of sensory symptoms suggestive of upper-airway and laryngeal neural dysfunction. Additionally, patients often report cough triggered by low-level physical and chemical stimuli, which is suggestive of cough-reflex hyperresponsiveness. ⋯ In this Personal View, we argue that chronic cough is a neuropathic disorder that arises from neural damage caused by a range of inflammatory, infective, and allergic factors. In support of this idea, we discuss evidence of successful treatment of chronic cough with agents used for treatment of neuropathic pain, such as gabapentin and amitriptyline. Regarding cough as a neuropathic disorder could lead to new, more effective antitussives.

Diffuse alveolar damage is the histological hallmark of acute respiratory distress syndrome (ARDS). However, the chronology of histological lesions is not well established. We aimed to determine the time to onset of exudative or proliferative changes and end-stage fibrosis in ARDS. ⋯ None.

Randomized Controlled Trial Multicenter Study Observational Study
Treatment of low bone density in young people with cystic fibrosis: a multicentre, prospective, open-label observational study of calcium and calcifediol followed by a randomised placebo-controlled trial of alendronate.
Long-term complications of cystic fibrosis include osteoporosis and fragility fractures, but few data are available about effective treatment strategies, especially in young patients. We investigated treatment of low bone mineral density in children, adolescents, and young adults with cystic fibrosis. ⋯ Telethon Foundation (Italy).
