Long-term effects of childhood chest infections
As paediatricians we are sometimes guilty of underestimating the possible consequences in adult life of common childhood illnesses. Children with acute lower respiratory infections (LRIs) are usually treated and discharged, with full reassurance that their lungs will subsequently be normal. However the findings of a very long-term follow-up cohort study from Tucson, Arizona are far from reassuring (Chan JC, et al. Pediatrics 2015:135;607–616). Around 1240 children born between 1980 and 1984 were followed up with spirometry and symptom questionnaires at intervals to age 29 years. Data had already been gathered on occu...

Question 2: Should 0.9% saline be used for maintenance fluids in hospitalised children?
Scenario A 6-year-old boy with severe tonsillitis requires intravenous maintenance fluids. As a new specialist registrar to this hospital you are unfamiliar with their fluid policy. The nurse informs you that the routine intravenous solution used is 0.45% sodium chloride with 5% dextrose. This is not what you are familiar with having previously used 0.9% sodium chloride with 5% dextrose. You are unsure what the evidence for isotonic versus hypotonic fluid is in children requiring intravenous maintenance fluids, in particular the effect on serum sodium.

Interventional Therapeutic Strategy for Hemoptysis Originating from Infectious Pulmonary Artery Pseudoaneurysms
This study reports 6 cases of hemoptysis originating from infectious pulmonary artery pseudoaneurysms (PAPs). Selective pulmonary angiography revealed PAPs in 5 cases, and segmental pulmonary artery embolization was performed using coils and gelatin sponge particles. Systemic arterial embolization also was performed in 5 cases because of inadequate initial control or for shunts from systemic to pulmonary arteries. At a median follow-up time of 9 months (range, 25 d to 25 mo), no recurrence occurred, although 2 patients died of respiratory failure. Segmental artery embolization combined with systemic artery embolization may...

A Phenotypic High-Throughput Screen with RSV-Infected Primary Human Small Airway Epithelial Cells (SAECs)
Respiratory syncytial virus (RSV) is a commonly occurring pathogen that can cause severe disease in children, the elderly, and immunocompromised individuals with a large, unmet clinical need. We developed a high-throughput, primary cell-based antiviral RSV assay to enable identification of small molecules using cytopathic effect (CPE) as a phenotypic end point. To provide increased biological relevance, we developed our assay with primary human small airway epithelial cells (SAECs), which originate from known sites of RSV infection and replication instead of a more traditional immortalized cell line. Using purchased low-pa...

Fatal Progression of Gorham Disease: a case report and review of the literature
Gorham disease is an idiopathic massive osteolysis, and maxillofacial involvement is rare. Here, we report a case of a 12-year-old boy suffering from severe progressive osteolysis in the mandible, hyoid bone, mastoid process, and cervical spine. Radiation therapy and α-interferon therapy were followed by bisphosphonate therapy. The patient died due to respiratory failure. To describe the clinicopathological features of Gorham disease of the jaws with emphasis on the fatal types, 64 cases in the literature were reviewed.

Increased intra- and extracellular granzyme expression in patients with tuberculosis
Tuberculosis (TB) is an important cause of morbidity and mortality worldwide. Granzymes (gzms) are proteases mainly found in cytotoxic lymphocytes, but also extracellularly. While the role of gzms in target cell death has been widely characterized, considerable evidence points towards broader roles related to infectious and inflammatory responses. To investigate the expression of the gzms in TB, intracellular gzms A, B and K were measured by flow cytometry in lymphocyte populations from peripheral blood mononuclear cells from 18 TB patients and 12 healthy donors from Bangladesh, and extracellular levels of gzmA and B were ...

Ventilation and Diaphragm Activity during Sustained Hypoxia in Awake Canines
We examined the effect of moderate isocapnic hypoxia (SpO2 80%) sustained for 20minutes in 13 adult, awake, intact canines. The ventilatory response to sustained isocapnic hypoxia in these canines was not maintained: after an initial brisk response, ventilation declined significantly to an intermediate plateau. The hypoxic ventilatory decline occurred via a decrease in tidal volume, without change in breathing frequency. Distinct from airflow, costal diaphragm EMG showed a concurrent decline during sustained isocapnic hypoxia. However, the change in ventilation during sustained hypoxia in canines was very different from th...

Neutralization of enterovirus D68 isolated from the 2014 US outbreak by commercial intravenous immune globulin products
Enterovirus D68 (EV-D68) belongs to the Enterovirus genus (Picornaviridae family) of non-enveloped, positive sense, single-stranded RNA viruses that commonly infect humans. Initially isolated from children with pneumonia and bronchiolitis in 1962, EV-D68 has been the cause of isolated clusters of acute respiratory disease in children in the United States from 1989 to 2010[1,2]. The recent 2014 outbreak represents the largest and most widespread EV-D68 outbreak to date with 1153 laboratory-confirmed cases since August . (Source: Journal of Clinical Virology)

Linear and nonlinear dynamics of heart rate variability in the process of exposure to 3600 m in 10 min
Abstract Acute hypoxia activates several autonomic mechanisms, mainly in cardiovascular system and respiratory system. The influence of acute hypoxia on linear and nonlinear heart rate variability (HRV) has been studied, but the parameters in the process of hypoxia are still unclear. Although the changes of HRV in frequency domain are related to autonomic responses, how nonlinear dynamics change with the decrease of ambient atmospheric pressure is unknown either. Eight healthy male subjects were exposed to simulated altitude from sea level to 3600 m in 10 min. HRV parameters in frequency domain were analyzed by ...

Platelet-rich Plasma Extract Accelerates Lung Regeneration Through the LRP5-Tie2 Pathway.
In this report, we have demonstrated that mouse PRP extract increases phosphorylation levels of the Wnt co-receptor low-density lipoprotein receptor-related protein 5 (LRP5), and thereby activates angiogenic factor receptor Tie2 in endothelial cells (ECs) and accelerates EC sprouting and lung epithelial cell budding in vitro. PRP extract also increases phosphorylation levels of Tie2 in the mouse lungs and accelerates compensatory lung growth and recovery of exercise capacity after unilateral pneumonectomy in mice, while soluble Tie2 receptor or Lrp5 knockdown attenuates the effects of PRP extract. Since human PRP extract i...

Deficiency Mutations of α1-antitrypsin Differentially Affect Folding, Function and Polymerization.
Abstract Misfolding, polymerisation and defective secretion of functional α1-antitrypsin underlies the predisposition to severe liver and lung disease in α1-antitrypsin deficiency. We have identified a novel (Ala336Pro, Baghdad) deficiency variant and characterised it relative to the wild-type (M) and Glu342Lys (Z) alleles. The index case is a homozygous individual of consanguineous parentage, with levels of circulating α1-antitrypsin in the moderate deficiency range, but a biochemical phenotype that could not be classified by standard methods. The majority of the protein was present as functionally inactive pol...

Identification of a short interspersed repetitive element insertion polymorphism in the porcine MX1 promoter associated with resistance to porcine reproductive and respiratory syndrome virus infection.
In this study, we demonstrate that positive elements are present in the two promoter regions of -2713 to -2565 and -688 to -431 in the porcine MX1 gene. Sequencing and alignment of the amplified porcine MX1 gene promoter region identified a short interspersed repetitive element (SINE) insertion of 275 bp at site -547. At this site, allele B (an insertion of 275 bp) is dominant in Chinese indigenous pig breeds but has a workable minor allele frequency in western lean-type pig breeds. Luciferase activity was compared between promoters with and without the insertion of the 275-bp fragment in transiently transfected MARC-145...

Validation and clinical application of a nested PCR for paracoccidioidomycosis diagnosis in clinical samples from Colombian patients.
Abstract Paracoccidioidomycosis is a systemic and endemic mycosis, restricted to tropical and subtropical areas of Latin America. The infection is caused by the thermal dimorphic fungus Paracoccidioides brasiliensis and Paracoccidioides lutzii. The diagnosis of paracoccidioidomycosis is usually performed by microscopic examination, culture and immunodiagnostic tests to respiratory specimens, body fluids and/or biopsies; however these methods require laboratory personnel with experience and several days to produce a result. In the present study, we have validated and evaluated a nested PCR assay targeting the gene e...

Home Oxygen Program review: Regionalization in Vancouver Coastal Health and British Columbia.
Abstract Since its inception in the 1980s, the Home Oxygen Program in British Columbia was centrally managed by the Ministry of Health. Initially a small program with few clients across the province, it soon became a large program with many clients and increasing expenditures. A pilot program started in Victoria (British Columbia) in 1996 demonstrated that managing the program locally could offer better client care, better contract management and significant cost savings. In 2002, the pilot's model and recommendations were implemented in British Columbia's five health authorities. The present review details the exp...
