The active identification and management of chronic refractory breathlessness is a human right
Chronic refractory breathlessness is defined as breathlessness at rest or on minimal exertion that will persist chronically despite optimal treatment of the underlying cause(s). At any time, 1% of the population report a modified Medical Research Council dyspnoea score of ≥3 chronically. Despite the prevalence, severity and chronicity of this symptom and an evidence base of affordable and safe interventions, chronic refractory breathlessness remains grossly undertreated. Many patients and clinicians accept the presence of the chronic refractory breathlessness as an inevitable part of an illness, with no thought of treat...

Pleural nodules in a patient with a colonic tumour
Case presentation A 58-year-old woman underwent chest CT to monitor a colonic tumour diagnosed 1 year previously. Axial and coronal CT images showed multiple well-circumscribed pleural-based nodules in the left lower hemithorax, and the absence of the spleen in the left upper quadrant (figure 1). Routine blood work demonstrated no significant laboratory abnormality. The patient also had a history of a gunshot wound that transfixed the thoracoabdominal region 40 years previously. Thoracotomy was performed and disclosed multiple reddish-purple nodules on the pleural surface (figure 2). What is the most probable dia...

A young girl with apparent treatment-resistant asthma treated at Bambino Gesu children's hospital
Francesca Petreschi (FP): A 9.8 year–old-girl was first admitted in our unit for a persistent bronchospasm, poorly responsive to salbutamol, and progressive onset of respiratory distress after spontaneous expectoration of a bronchial cast (figure 1A). Her clinical history was uneventful until she was 7 years old, when she suffered from two subsequent bouts of pneumonia, but no admission was required. In the following years, she presented few episodes of bronchospasm, clinically diagnosed, with good response to bronchodilator and no limitation on her daily activities. Her family history was positive for allergic ...

Congenital thoracic malformation
A 31-year-old man presented with recurrent chest pain. CT coronary arteriography (figure 1) demonstrated a well-defined area of hypertransradiancy at the left lung base supplied by a large artery arising from the thoracic aorta (figure 2) with no normal bronchial or pulmonary artery communication, but normal pulmonary venous drainage. The diagnosis is that of congenital bronchial atresia with a systemic artery supply (also termed intralobar sequestration).1 Congenital pulmonary abnormalities are being detected increasingly frequently as incidental findings during cross-sectional imaging performed for other reasons. Managem...

What's hot that the other lot got
Upper airway stimulation for obstructive sleep apnoea In this multicentre, prospective cohort study (N Engl J Med 2014;370:139–49), the clinical safety and efficacy of upper airway stimulation in 126 patients with moderate to severe obstructive sleep apnoea who had difficulty adhering to CPAP were evaluated. Upper airway pacing of the hypoglossal nerve, coordinated with ventilatory effort, led to significant improvement in subjective and objective measures of the severity of obstructive sleep apnoea. Median apnoea-hypopnoea index at 12 months reduced 68%, from 29.3 events/h to 9.0 events/h (p<0.001). Oxygen d...

Benefits of whole-body vibration to people with COPD: a community-based efficacy trial
Conclusions: Results showed that WBV did not exacerbate symptoms of COPD that can be associated with physical inactivity. The WBV intervention improved tests to simulate ADLs such as rising from a chair, turning, and walking gait with greater effect than a SWBV intervention. If a placebo effect was systemic to the WBV intervention, the effect was negligible. As a standalone community-based intervention, WBV was an efficacious mode of exercise training for people with stable COPD that did not negatively effect exercise tolerance or exacerbate the disease, while concurrently improving functional performance of the lower limb...

Multifocal subdural hematomas as the presenting sign of acquired hemophilia A: a case report
Conclusions: Subdural hematomas as the initial sign of AHA are all but unknown in the medical literature. We bring this entity to the attention of the neurology community because lumbar puncture and/or conventional angiogram are often indicated in the work-up of idiopathic multifocal subdural hematomas, but may be dangerous in patients with AHA.

The relationship between hypotension, cerebral flow and the surgical field during endoscopic sinus surgery
Conclusions: Hypotensive anesthesia is an effective method of controlling intraoperative bleeding during endoscopic sinus surgery, however in low MAP ranges the effect is clinically small. In otherwise healthy patients undergoing endoscopic sinus surgery with general anesthesia, reducing MAP below 60mmHg may increase the risk of cerebral ischemia. (Source: The Laryngoscope)

Motile cilia harbor serum response factor as a mechanism of environment sensing and injury response in the airway.
Abstract Non-motile primary cilia are recognized as important sensory organelles during development and normal biological functioning. For example, recent work demonstrates that transcriptional regulators of the sonic hedgehog signaling pathway localize to primary cilia and participate in sensing and transducing signals regarding the cellular environment. In contrast, motile cilia are traditionally viewed as mechanical machinery, vital for the movement of solutes and clearance of bacteria and debris, but not participants in cellular sensing and signaling mechanisms. Recently, motile cilia were found to harbor recep...

Absence of c-Jun N-Terminal Kinase 1 protects against House Dust Mite-induced pulmonary remodeling but not Airway Hyperresponsiveness and Inflammation.
Abstract Chronic allergic asthma leads to airway remodeling and subepithelial fibrosis via mechanisms not fully understood. Airway remodeling is amplified by pro-fibrotic mediators, such as TGF-β1, which plays a cardinal role in various models of fibrosis. We recently have identified a critical role for JNK1 in augmenting the pro-fibrotic effects of TGF-β1, linked to epithelial to mesenchymal transition of airway epithelial cells. To examine the role of JNK1 in HDM-induced airway remodeling, we induced allergic airway inflammation in WT and JNK1-/- mice by administration of HDM extract. WT and JNK1-/- mice were s...

Cigarette Smoke-induced Mitochondrial Fragmentation and Dysfunction in Human Airway Smooth Muscle.
Abstract The balance between mitochondrial fission and fusion is crucial for mitochondria to perform its normal cellular functions. We hypothesized that cigarette smoke (CS), disrupts this balance and enhances mitochondrial dysfunction in the airway. In non-asthmatic human airway smooth muscle (ASM) cells, CS extract (CSE) induced mitochondrial fragmentation and damages their networked morphology in a concentration-dependent fashion, via increased expression of mitochondrial fission protein Drp1 and decreased fusion protein Mfn2. CSE effects on Drp1 vs. Mfn2 and mitochondrial network morphology involved ROS, activa...

The Integrated Stress Response in Lung Disease.
Abstract Lungs are repeatedly exposed to inhaled toxic insults, such as smoke, diesel exhaust and microbes, which elicit cellular stress responses. The phosphorylation of eIF2α by one of four stress-sensing kinases triggers a pathway called the integrated stress response (ISR) that helps protect cellular reserves of nutrients and prevents the accumulation of toxic proteins. In this review, we will discuss how activation of the ISR has been shown to play an important role in pulmonary pathology and how its study may help in the development of novel therapies for diverse conditions from hypoxia to cancer.

Chronic active Epstein-Barr virus infection mimicking autoimmune hepatitis exacerbation in a patient with systemic lupus erythematosus.
We report a very rare case with autoimmune hepatitis (AIH) complicated by CAEBV. A 50-year-old woman with systemic lupus erythematosus (SLE) complicated by AIH began to suffer from acute respiratory failure and her clinical symptoms improved rapidly in response to steroid treatment. However, during the gradual tapering of the steroid dose, a steady increase of the serum hepatobiliary enzyme levels subsequently was observed and the patient began to have continuous fever. Moreover, upper gastrointestinal endoscopy revealed multiple intractable gastric ulcers. When EBER-ISH was performed on liver biopsy and gastric mucosal bi...

Off-pump versus on-pump revascularization in females: a meta-analysis of observational studies.
CONCLUSIONS: OPCAB is a safe alternative to ONCAB in the surgical revascularisation of female patients and may reduce post-operative myocardial infarction (MI). However, this does not translate into a reduction in 30-day mortality and OPCAB does not significantly improve other cardiovascular, renal or neurological outcomes. Late outcome data remains lacking and a well-structured, randomized trial is required to answer vital questions regarding the effect of OPCAB on women in the long-term.

G‐scores: A method for identifying disease‐causing pathogens with application to lower respiratory tract infections
AbstractLower respiratory tract infections (LRTIs) are well known for the lack of a good diagnostic method. The main difficulty lies in the fact that there are a variety of pathogens causing LRTIs, and their management and treatment are quite different. The development of quantitative real‐time loop‐mediated isothermal amplification (qrt‐LAMP) made it possible to rapidly amplify and quantify multiple pathogens simultaneously. The question that remains to be answered is how accurate and reliable is this method? More importantly, how are qrt‐LAMP measurements utilized to inform/suggest medical decisions? When does a ...

Recurrent laryngeal inflammatory myofibroblastic tumor with positive anaplastic lymphoma kinase mimicking recurrent respiratory papillomatosis: a case report
Inflammatory myofibroblastic tumor (IMT) of the larynx is an unusual lesion, particularly in the pediatric age group. Laryngeal IMTs in children follow a benign clinical course with reports of only rare recurrences and no metastases. Although anaplastic lymphoma kinase (ALK) has been associated with IMTs, there is only one pediatric laryngeal IMT reported to be ALK-positive with immunohistochemical staining. Here, we present a case of a 10-year-old boy with a laryngeal IMT that recurred four times and was misdiagnosed as recurrent respiratory papillomatosis after the initial three operations. ALK positivity was demonstrate...

Prostaglandin E2 reduces Toll-like Receptor 4 Expression in Alveolar Macrophages by Inhibition of Translation.
Abstract Alveolar macrophages (AMs) represent the first line of innate immune defense in the lung, and they utilize pattern recognition receptors (PRRs) to sense pathogens. The best studied PRR is Toll-like receptor 4 (TLR4), which detects lipopolysaccharide (LPS) from Gram-negative bacteria. The lipid mediator prostaglandin E2 (PGE2) is well-established to dampen AM immune responses by inhibiting the signaling events downstream of PRRs. Here we examined the effect of PGE2 on TLR4 expression itself in rat AMs. Although PGE2 did not reduce the mRNA levels of TLR4, it did decrease TLR4 protein levels. The translation...
