An 18-year-old male presented to our hospital with complaints of episodic abdominal pain, dry cough and right pleuritic chest pain. He was diagnosed as a case of right tuberculous pleural effusion on the basis of the pleural fluid Genexpert report of Mycobacterium tuberculosis detected sensitive to rifampicin and was started on antituberculous therapy. Forty-five days later, he presented with acute onset breathlessness, swelling of the right leg, streaky haemoptysis and a fresh left-sided pleural effusion. Evaluation revealed venous thromboembolism (right lower lobar segment pulmonary embolism with right leg deep vein thrombosis)...

We report a first case of a patient experiencing reactivation of pulmonary tuberculosis (TB) during treatment of oral tyrosine kinase inhibitor (TKI) with non-small cell lung cancer (NSCLC). A 44-year-old male patient visited the hospital with cough. He had been treated with erlotinib (oral TKI) for 8 months after being diagnosed as NSCLC with sensitive epidermal growth factor receptor mutation in our clinic. At initial chest imaging, the patient had fibroatelectatic calcified granuloma in the right upper lobe (RUL) apex as well as 1...

Cough is the most common reason to visit a primary care physician, yet it remains an unmet medical need. Fatty acid amide hydrolase (FAAH) is an enzyme that breaks down endocannabinoids, and inhibition of FAAH produces analgesic and anti-inflammatory effects. Cannabinoids inhibit vagal sensory nerve activation and the cough reflex, so it was hypothesised that FAAH inhibition would produce antitussive activity via elevation of endocannabinoids.Primary vagal ganglia neurons, tissue bioassay, in vivo electrophysiology and a conscious guinea pig cough model were utilised to investigate a role for fatty acid amides in modulating sensory nerve activation in vagal afferents...

We herein describe the first known case of pleuritis caused by Mycobacterium kyorinense without pulmonary involvement. A 48-year-old man undergoing immunosuppressant therapy presented with cough and dyspnea. An accumulation of pleural fluid was noted; however, computed tomography revealed no pulmonary lesions. Cultures of the fluid yielded non-tuberculous mycobacteria, which was identified as Mycobacterium kyorinense. The patient recovered after 6 months of therapy with clarithromycin and moxifloxacin. Clinicians should be aware that Mycobacterium kyorinense can cause pleuritis without pulmonary involvement...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with cough, sputum production or dyspnoea and a reduction in lung function, quality of life and life expectancy. Apart from smoking cessation, there are no other treatments that slow lung function decline. Roflumilast and cilomilast are oral phosphodiesterase 4 (PDE4) inhibitors proposed to reduce the airway inflammation and bronchoconstriction seen in COPD. This is an update of a Cochrane review first published in 2011 and updated in 2013...

Importance: Chronic cough is a debilitating, often multifactorial problem. Vagal neuropathy has been proposed as a cause for a fraction of these cases. There are certain features that support the clinical diagnosis of vagal neuropathy. It is hypothesized that patients with neurogenic cough who have vocal fold motion asymmetry (VFMA) on laryngoscopy will be more likely to respond to gabapentin. Objective: To evaluate the association between the history, physical and videostroboscopic examinations, and clinical response to gabapentin...

On November 21, 2016, the U.S. Food and Drug Administration granted regular approval to daratumumab in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of patients with multiple myeloma who have received at least one prior therapy. Approval was based on two randomized, open-label trials in which daratumumab was added to these backbone therapies. The MMY3003 trial demonstrated substantial improvement in progression-free survival (PFS) when daratumumab was added to lenalidomide and dexamethasone compared with lenalidomide and dexamethasone alone...

The currently available antihypertensive agents have undesirable adverse effects due to systemically altering target activity including receptors, channels, and enzymes. These effects, such as loss of potassium ions induced by diuretics, bronchospasm by beta-blockers, constipation by Ca(2+) channel blockers, and dry cough by ACEI, lead to non-compliance with therapies (Moser, 1990). Here, based on new hypertension mechanisms, we explored a new antihypertensive approach. We report that transient receptor potential vanilloid 4 (TRPV4) interacts with Ca(2+)-activated potassium channel 3 (KCa2...

This case series reviews two cases of elderly patients who presented with fever, cough and shortness of breath. Clinical examinations and initial chest radiographs confirmed unilateral pleural effusion. Thoracenteses were consistent with exudative pleural effusion. We commenced intravenous antibiotics treating for parapneumonic effusions. The first case showed persistent effusion despite drainage, and the second case had a little aspirate from pleural tapping. Subsequent ultrasound of the thorax showed multiloculated effusions...

BACKGROUND: Poor access to essential medicines is common in many low- and middle-income countries, partly due to an insufficient and inadequately trained workforce to manage the medicines supply chain. We conducted a prospective impact evaluation of the training and deployment of pharmacy assistants (PAs) to rural health centers in Malawi. METHODS: A quasi-experimental design was used to compare access to medicines in two districts where newly trained PAs were deployed to health centers (intervention) and two districts with no trained PAs at health centers (comparison)...

Dogs receiving radiation can develop complications unrelated to the radiation treatment. No study to date has described these complications in clinical patients undergoing multiple radiation therapy treatments. The purpose of this retrospective case-control study was to characterize the incidence and type of complications that occur in these dogs. A secondary goal was to evaluate whether patient and treatment characteristics could be identified to predict the risk of these complications. Medical records of 268 dogs receiving at least one radiation treatment at a single institution, between September, 2004 and June, 2007 were reviewed...

Mammals have evolved neurophysiologic reflexes, such as coughing and scratching, to expel invading pathogens and noxious environmental stimuli. It is well established that these responses are also associated with chronic inflammatory diseases, including asthma and atopic dermatitis. However, the mechanisms by which inflammatory pathways promote sensations such as itch remain poorly understood. Here, we show that type 2 cytokines directly activate sensory neurons in both mice and humans. Further, we demonstrate that chronic itch is dependent on neuronal IL-4Rα and JAK1 signaling...

Pulmonary actinomycosis is a rare yet important and challenging diagnosis to make. It is commonly confused with other lung diseases, such as tuberculosis and bronchogenic carcinoma, leading to delay diagnosis or misdiagnosis. A 49-year-old man presented with a chronic cough, hemoptysis, and pleuritic chest pain. His initial imaging studies including computed tomography (CT) was suggestive of bronchogenic carcinoma. A subsequent CTguided biopsy was consistent with pulmonary actinomycosis and excluded the possibility of bronchogenic carcinoma...
