Complications associated with laparoscopic adrenalectomy: Description and standardized assessment
Conclusions Standardized criteria of surgical complications are necessary. Standardization is possible by combined application of two tools. We believe that this evaluation concept of the surgery morbidity must be used systematically in order to achieve a new standard refined, concise and comparative for reports of adverse perioperative events.

Lung involvement in children with lysinuric protein intolerance
Conclusion PAP is a constant feature in children with LPI and lung involvement. Pulmonary fibrosis is frequent and these two pathologies may develop independently. This study shows the heterogeneity of presentation and outcome. Lung injury could be secondary to impaired phagocytic function and abnormal inflammatory and immune responses intrinsic to the SLC7A7 mutant phenotype. HRCT is recommended to detect lung involvement.

Sputum club cell protein concentration is associated with pulmonary exacerbation in cystic fibrosis
Cystic fibrosis (CF) patients exhibit a progressive decline in lung function accelerated by intermittent pulmonary exacerbations. There are urgent needs for clinically relevant biomarkers to aid in the diagnosis and management of a CF pulmonary exacerbation, in addition to providing insight into its pathophysiology. Club cell secretory protein (CCSP) is produced by bronchial epithelial cells, known to have anti-inflammatory properties and may play a role in CF pulmonary exacerbations. Our objective was to measure sputum CCSP concentration during hospitalizations for CF pulmonary exacerbation and during quarterly outpatient...

The effect of short-term, high-dose oral N-acetylcysteine treatment on oxidative stress markers in cystic fibrosis patients with chronic infection — A pilot study
Patients with cystic fibrosis (CF) and chronic Pseudomonas aeruginosa lung infection have increased oxidative stress as a result of an imbalance between the production of reactive oxygen species caused by inflammation and their inactivation by the impaired antioxidant systems. Supplementation with anti-oxidants is potentially beneficial for CF patients. (Source: Journal of Cystic Fibrosis)

Improving mitochondrial bioenergetics under ischemic conditions increases warm ischemia tolerance in the kidney.
IMPROVING MITOCHONDRIAL BIOENERGETICS UNDER ISCHEMIC CONDITIONS INCREASES WARM ISCHEMIA TOLERANCE IN THE KIDNEY. Am J Physiol Renal Physiol. 2014 Oct 22; Authors: Szeto HH, Liu S, Soong Y, Birk AV Abstract Ischemia time during partial nephrectomy is strongly associated with acute and chronic renal injury. ATP depletion during warm ischemia inhibits ATP-dependent processes, resulting in cell swelling, cytoskeletal breakdown and cell death. The duration of ischemia tolerated by the kidney depends on the amount of ATP that can be produced with residual substrates and oxygen in the tissue to sustain cell f...

Rho-kinase Mediates Right Ventricular Systolic Dysfunction in Rats with Chronic Neonatal Pulmonary Hypertension.
Conclusions: Pressure unloading and regressed arterial and cardiac remodeling did not lead to recovery of systolic function while right ventricular Rho-kinase activity remained increased. Right ventricle-specific up-regulation of RhoA/Rho-kinase activity is critical to hypoxia-mediated systolic dysfunction, in part by regulating the activity of phosphodiesterase 5.

Ethical Dilemmas of Adult ECMO: Emerging Conceptual Challenges
EXTRACORPOREAL MEMBRANE OXYGENATION (ECMO) is an invaluable rescue therapy for patients with refractory respiratory or cardiac failure. Recent developments in cardiopulmonary bypass technology, such as miniaturized extracorporeal devices, heparin-coated circuits, and percutaneous cannulation techniques, have facilitated widespread application of ECMO in different clinical situations.1 The decision to initiate ECMO is made more difficult by uncertainties surrounding who might most benefit from it.

Supraglottic epithelial hyperplasia in association with guttate psoriasis
Supraglottic epithelial hyperplasia is rare in the pediatric population, and typically presents in adults as a sequelae of radiation therapy or progressive autoimmune disease. Guttate psoriasis typically presents in young adults following an inflammatory trigger such as an upper respiratory infection or streptococcal pharyngitis. A case of stridorous episodes heralded by flares guttate psoriasis is presented. Pathologic analysis demonstrated supraglottic epithelial hyperplasia. This case demonstrates a rare cause of stridor and upper airway obstruction in children. (Source: International Journal of Pediatric Otorhinolaryngology Extra)

Characterisation of novel linear antigen epitopes on North American-type porcine reproductive and respiratory syndrome virus M protein
In this study, two different Mab clones targeting the linear epitopes on the PRRSV M protein were generated and characterized. Both Mabs showed binding activity against the native PRRSV virion and recombinant M protein when analyzed by immunofluorescence assay (IFA) and Western blot. The targeted epitope of each Mab was mapped by serial truncation of the M protein to generate overlapping fragments. Fine epitope mapping was then performed using a panel of expressed polypeptides. The polypeptide sequences of the two epitopes recognized by Mabs 1C8 and 3F7 were 3SSLD6 and 155VLGGRKAVK163, respectively, with the former bei...

[Series] Emerging viral respiratory tract infections—environmental risk factors and transmission
The past decade has seen the emergence of several novel viruses that cause respiratory tract infections in human beings, including Middle East respiratory syndrome coronavirus (MERS-CoV) in Saudi Arabia, an H7N9 influenza A virus in eastern China, a swine-like influenza H3N2 variant virus in the USA, and a human adenovirus 14p1 also in the USA. MERS-CoV and H7N9 viruses are still a major worldwide public health concern. The pathogenesis and mode of transmission of MERS-CoV and H7N9 influenza A virus are poorly understood, making it more difficult to implement intervention and preventive measures.

[Comment] Investment in pneumonia and pneumococcal research
The worldwide burden of pneumonia is high—the disease caused 1·2 million deaths in 2010, mostly in children younger than 2 years. In the same year, at least 76·7 million disability-adjusted life-years (DALYs) were attributed to pneumonia and pneumococcal disease, although DALYs are inevitably increased in diseases that mostly affect young children. Infections of the lower respiratory tract (many of which are probably pneumonia-related) were the single largest cause of worldwide DALYs in children younger than 1 year.

[Comment] Treating MERS-CoV during an outbreak
When a new virus emerges, health-care systems face major challenges, not least of which is deciding which treatments to use. The drug development process, from novel compound screening to final approval, can take more than 10 years to complete and cost hundreds of millions of dollars. By contrast, viruses can emerge rapidly, spread widely, and pose a substantial, immediate threat to public health. For example, Middle East respiratory syndrome coronavirus (MERS-CoV) was first reported in November, 2012, and, as of September, 2014, cases have been reported in 21 countries, with 837 confirmed cases and 319 deaths.

[Editorial] Enterovirus D68: the unexpected guest
Reports of increasing numbers of children admitted to hospital with severe respiratory illness and associated muscle weakness and paralysis in the USA and Canada have caused alarm. Enterovirus D68—a member of the enterovirus genus that also includes rhinoviruses, coxsackieviruses, and polioviruses—is believed to be the most likely cause of this outbreak. Infections caused by this virus are rarely reported (only 79 cases were recorded between 2009 and 2013 in the USA) and they normally involve mild respiratory symptoms similar to a cold, but these can become severe in children with underlying problems such as asthma.

Effect of Laparotomy on the Swallow–Breathing Relationship in the Cat
Abstract Swallow occurs predominantly in the expiratory phase (E) of breathing. This phase preference is thought to contribute to airway protection by limiting the passage of material through the pharyngeal airway with little or no inspiratory (I) airflow. This phase preference is attributed to central interactions between the swallow and breathing pattern generators. We speculated that changes in peripheral mechanical factors would influence the respiratory phase preference for swallow initiation. We induced swallowing in anesthetized spontaneously breathing cats by injection of water into the oropharynx. In anim...

Shear stress upregulates IL‐1β secretion by Chlamydia pneumoniae‐ infected monocytes
Abstract Infectious agents are increasingly implicated in the development and progression of chronic inflammatory diseases. Several lines of evidence suggest that the common intracellular respiratory pathogen, Chlamydia pneumoniae contributes to the well‐established risk factors of atherosclerosis but the exact mechanism is not well understood. It is believed that C. pneumoniae‐infected monocytes travel from the lung to the atherosclerotic foci, during which the cells experience mechanical stimuli due to blood flow.

Tuberculous pleuritis secondary to Mycobacterium bovis in a veterinarian
Abstract Mycobacterium bovis is a rare cause of tuberculosis in humans, but should be considered in individuals at risk secondary to medical co‐morbidities (notably immunocompromise) or occupational exposure. Most cases are secondary to re‐activation of latent infection in elderly individuals although cases of primary infection still occur, usually involving animal‐to‐human transmission. Pleural fluid culture in the context of suspected tuberculous pleuritis is frequently negative and pleural biopsy significantly increases the likelihood of confirming the diagnosis histologically and microbiologically.
