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...

Dry cough is a common symptom described in patients with Idiopathic Pulmonary Fibrosis (IPF) and impairs quality of life. The exact mechanisms causing cough in IPF remain unclear, however evidence suggests altered cough neurophysiology and sensitisation plays a role; IPF patients have an enhanced cough reflex sensitivity to inhaled capsaicin. The Transient Receptor Potential Vanniloid-1 channel (TRPV-1) has a role in the cough reflex and airway expression is increased in patients with chronic cough. The Ankyrin-1 receptor (TRPA-1) is often co-expressed...

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease characterised by alveolar accumulation of surfactant composed of proteins and lipids. Three main categories of PAP have been defined depending on the aetiology: primer/idiopathic, neonatal/congenital, secondary and exogenous/environmental exposure. Radiologically diffuse ground glass opacities, interlobular and intralobular septal thickening is seen. Although open lung biopsy is accepted as the gold standard in diagnosis, it can be diagnosed by showing bronchoalveolar lavage (BAL) fluid with a milky appearance and periodic acid-schiff (PAS) positive globules in biopsy with clinical and radiological findings...

Heart failure is a rare cause of wheezing and may develop into a critical condition in children. Few cases report patients with heart failure, secondary to dilated cardiomyopathy, with high fever. A 23-month-old girl visited the emergency department with high fever, cough, first wheezing episode, chest retraction and tachycardia. The chest X-ray revealed consolidation on the left lower lung field; the cardiothoracic ratio was 60%. She was diagnosed with bronchial asthma triggered by pneumonia, which remained unchanged during four visits...

Plastic bronchitis is a rare disorder characterized by formation of large, branching bronchial casts, which are often expectorated. We present an interesting case of a 35-year-old woman who presented for evaluation of a chronic cough productive of voluminous secretions. Clinical and radiological examination confirmed a total left lung atelectasis without any pathological mediastinal node. Flexible bronchoscopy demonstrated tenacious, thick, and sticky whitish secretions blocking the left stem bronchus. This material was extracted, and inspection demonstrated a bronchial cast, whose pathological analysis revealed necrotic epithelial cells, some eosinophils, and Charcot-Leyden crystals...

A 67-year-old man was admitted to our hospital complaining of dry cough. Chest computed tomography showed diffuse infiltrates and ground-glass opacities in the bilateral lung fields. Transbronchial lung biopsy specimens showed alveoli filled with yeast-like fungi. With a diagnosis of pneumocystis pneumonia (PCP), he was given oral sulfamethoxazole/trimethoprim, to which he responded well. However, seven months later, PCP relapsed. Analyses revealed a low bronchoalveolar lavage fluid CD4/CD8 ratio of 0.04 and CD4+ lymphocytopenia (250/μL)...

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive lung disease characterized by progressive lung scarring and the histological picture of usual interstitial pneumonia (UIP). It is associated with increasing cough and dyspnoea and impaired quality of life. IPF affects ∼3 million people worldwide, with incidence increasing dramatically with age. The diagnostic approach includes the exclusion of other interstitial lung diseases or overlapping conditions and depends on the identification of the UIP pattern, usually with high-resolution CT; lung biopsy might be required in some patients...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) remains a poorly understood clinical entity. It is currently classified as a premalignant condition by the World Health Organization (WHO). Symptoms are similar to those associated with obstructive lung disease, including breathlessness and cough. The presentation is often initially ascribed to other diseases such as asthma or chronic obstructive pulmonary disease. Here, we present what we believe is the first described case of DIPNECH diagnosed by transbronchoscopic cryoprobe biopsy...

Little is known about when symptoms of idiopathic pulmonary fibrosis first develop. We identified incident cases of idiopathic pulmonary fibrosis-clinical syndrome (IPF-CS) from a UK primary care database and assessed the frequency of consultations for common symptoms in the 5 years prior to diagnosis. 1671 cases were identified with 5 years of data prior to diagnosis. Breathlessness was the most common symptom, followed by cough. Cases were significantly more likely than controls to experience these symptoms (p<0...

Idiopathic pulmonary fibrosis (IPF) is characterised by progressive changes of the lung architecture causing cough and dyspnoea and ultimately leading to lung failure and death. Today, for the first time, two drugs that may reduce the inexorable progression of the disease are available, suggesting that treatment with specific drugs for IPF should be started as soon as diagnosis is made. This applies to any disease and particularly to IPF, which is marked by a 5-year survival comparable or even worse than many cancers...

BACKGROUND: Cough can be a debilitating symptom of idiopathic pulmonary fibrosis (IPF) and is difficult to treat. PA101 is a novel formulation of sodium cromoglicate delivered via a high-efficiency eFlow nebuliser that achieves significantly higher drug deposition in the lung compared with the existing formulations. We aimed to test the efficacy and safety of inhaled PA101 in patients with IPF and chronic cough and, to explore the antitussive mechanism of PA101, patients with chronic idiopathic cough (CIC) were also studied...

Idiopathic pulmonary fibrosis (IPF) is a rare lung disease characterised by progressive loss of lung function, dyspnoea and cough. IPF has a variable clinical course but a poor prognosis. Nintedanib, a tyrosine kinase inhibitor, is one of two drugs approved for the treatment of IPF. In clinical trials, nintedanib slowed disease progression by reducing the rate of decline in forced vital capacity (FVC) in patients with IPF and mild or moderate lung function impairment. The effect of nintedanib was consistent across patient subgroups defined by baseline characteristics including FVC % predicted, diffusion capacity of the lung for carbon monoxide % predicted and the presence of emphysema...
