BACKGROUND: Chronic cough is a common symptom and related to several pulmonary, airway and heart diseases. When all likely medical explanations for the coughing are excluded, there remains a large group of patients with chronic coughing, which is mostly a cough reflex easily triggered by environmental irritants and noxious stimuli. The main aim of this study was to improve the diagnostic ability to differentiate chronic idiopathic cough (CIC) from asthma. METHODS: Twenty-three patients with CIC, 16 patients with mild asthma and 21 control participants were included...

AIMS: Anti-CD20 antibodies are increasingly being used to treat idiopathic nephrotic syndrome (INS) in children. While they may allow steroid and calcineurin-inhibitor withdrawal, repeated infusions of anti-CD20 antibodies are often required to maintain remission. Data on their potential toxicity in INS are needed to consider repeated infusions. METHODS: We reported data on side effects related to the use of rituximab (a chimeric anti-body; 130 pts) and ofatumumab (a humanized anti-body; 37 pts) in children with INS (steroid-dependent and steroid/calcineurin-inhibitor dependent disease) treated in a national referral center during a 9-year period (400 treatments; follow-up 1-9 years)...

BACKGROUND: The assessment of the clinical symptoms is the weakest link of the pulmonary embolism (PE) diagnostic algorithm. Despite the presence of highly sensitive and specific imaging methods, verifying PE remains difficult due to nonspecific clinical symptoms and frequently its subclinical course. OBJECTIVE: The aim of this study is to improve the recognition of PE by investigating the clinical presentation and short-term prognosis of unprovoked PE in comparison to provoked PE...

RATIONALE: Black pleural effusion (BPE) is an extremely uncommon type of pleural fluid, which can be due to infection, primary or metastatic malignancy, and hemorrhage. As reported in previous studies, BPE is also observed in some patients with pancreatic pseudocyst. PATIENT CONCERNS: We herein reported a case of a 14-year-old female patient who was admitted to our center with a history of cough for 1 and a half months and right chest pain for 1 month. Before this, she was consecutively hospitalized in 3 different hospitals due to the same symptoms...

Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease associated with debilitating symptoms of dyspnoea and cough, resulting in respiratory failure, impaired quality of life and ultimately death. Diagnosing IPF can be challenging, as it often shares many features with other interstitial lung diseases. In this article, we summarise recent joint position statements on the diagnosis and management of IPF from the Thoracic Society of Australia and New Zealand and Lung Foundation Australia, specifically tailored for physicians across Australia and New Zealand...

Cough is a common problem among cancer patients, especially lung cancer patients. Gabapentin has been shown to be effective in reducing cough number and severity in patients with idiopathic refractory cough. The authors report here the successful use of gabapentin at usual doses to treat cough in cancer patients, including two with lung cancer, with minimal side effects. Gabapentin may be a useful addition to the symptom management toolbox for palliation of cancer symptoms.

The clinical expression of idiopathic pulmonary fibrosis (IPF) is directly related to multiple alterations in lung function. These alterations derive from a complex disease process affecting all compartments of the lower respiratory system, from the conducting airways to the lung vasculature. In this article we review the profound alterations in lung mechanics (reduced lung compliance and lung volumes), pulmonary gas exchange (reduced diffusing capacity, increased dead space ventilation, chronic arterial hypoxaemia) and airway physiology (increased cough reflex and increased airway volume), as well as pulmonary haemodynamics related to IPF...

Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare disorder recently included in rare idiopathic interstitial pneumonias according to the updated American Thoracic Society/European Respiratory Society classification. IPPFE is characterized by pleural and subpleural parenchymal fibrosis causing volume loss predominantly in the upper lung lobes. Age of onset is variable, IPPFE mainly occurs in third and fourth decades. We present a 16 year old patient with a 2-year history of exertional dyspnea, nonproductive cough and weight loss...

Diffuse pulmonary ossification (DPO) is a rare disease characterized by metaplastic bone formation in the lung. There are few reports with a long-term follow-up of this disease. We herein report a 47-year-old man diagnosed with idiopathic DPO at 30 years of age. The patient's vital capacity was normal until 36 years of age (3.39 L, 82.4% predicted), but it was severely decreased when he visited the hospital again at 47 years of age due to cough and dyspnea (1.98 L, 44.6% predicted). Chest computed tomography showed a significant increase in the number of high-density nodules, suggesting that the progression of DPO had caused restrictive ventilatory impairment...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a lethal lung disease of unknown etiology. Patients present loss of lung function, dyspnea and dry cough. Diagnosis requires compatible radiologic imaging and, in undetermined cases, invasive procedures such as bronchoscopy and surgical lung biopsy. The pathophysiological mechanisms of IPF are not completely understood. Lung injury with abnormal alveolar epithelial repair is thought to be a major cause for activation of profibrotic pathways in IPF...

The technique of sputum induction and processing is a recognized non-invasive method allowing the collection and analysis of cells from the airways, which is interesting in various respiratory diseases like asthma, chronic obstructive pulmonary disease (COPD), chronic cough, or idiopathic pulmonary fibrosis. This technique is well tolerated, safe and non-invasive, but is currently limited to research services and specialized centers in clinical practice because it is technically demanding, time-consuming, and requires trained staff...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is hyperplasia of noninvasive neuroendocrine cells originating from Kultchitsky cells. This is a rare pathological condition, suspected to be a precursor lesion of carcinoid, together with tumorlet. In the WHO histological classification (4th edition) revised in 2015, DIPNECH was added to the category that includes neuroendocrine tumors. Our patient was a 77-year-old woman who initially visited another doctor because of coughing. Chest CT revealed a mass occluding the right intermediate bronchial trunk, and bronchial carcinoid was suspected from biopsy findings, leading to referral of this patient to our department...

Chronic idiopathic cough is a common and often frustrating complaint for patients as well as providers. When common etiologies of cough are ruled out and/or do not respond to usual treatments, neurogenic cough should be considered as a diagnosis of exclusion. Here, we report on a 58-year-old woman with an 8-year history of chronic, treatment-refractory cough of unknown etiology that we diagnosed as neurogenic cough and successfully treated with guanfacine monotherapy, with rapid and durable improvement in symptoms...

BACKGROUND AND AIM OF THE WORK: Idiopathic Pulmonary Fibrosis (IPF) is an interstitial lung disease, which progressively leads to severe disability and death. The average survival expectancy, ranges from 3 to 5 years from diagnosis, and the available medicines do not lead to healing. The progression of IPF lead to a decline in forced vital capacity (FVC), dyspnea, cough, continuous sleep interruptions, resulting in increased fatigue and deteriorating quality of life (QOL), progressive limitation of daily life activities and social life, with repercussions on psychological and emotional well-being, aggravated by anxiety, loss of sense of self-confidence and depression...

BACKGROUND Acute fibrinous organizing pneumonia (AFOP) is a rare condition of the lung that is associated with acute lung injury, and has a poor prognosis. AFOP is characterized histologically by intra-alveolar fibrin. AFOP has been described to be associated with lung infections, connective tissue disorders, drugs, toxic environmental exposure, and in lung transplantation. However, most cases of AFOP remain idiopathic, and because the condition can present with a wide variety of clinical manifestations, open lung biopsy or video-assisted thoracoscopic (VAT) lung biopsy is necessary for the diagnosis...
