Published: May 2015

AbstractMicroorganisms present multiple challenges in oilfield systems such as microbiologically influenced corrosion (MIC), reservoir souring, and biofouling. The misapplication of biocides can lead to significant issues in field operations, including resistance and/or lack of susceptibility of the microbial population to biocide treatment. The selection of chemistries to minimize microbial risk has traditionally relied on culture-based methods such as serial dilution to determine biocide efficacy. However, the diversity of microbes and the unique conditions found in each oil and gas asset make it very challenging to obtain reliable results through growth assays in culture media. Field-based molecular microbial enumeration technologies, such as the quantification of intracellular adenosine triphosphate (cATP) and adenosine monophosphate (cAMP) have advanced significantly in the past 5 years and are often relied upon to determine microbial risks in production systems. Additionally, laboratory based methods such as Flow Cytometry, quantitative-polymerase-chain-reaction (qPCR), and next-generation DNA sequencing (NGS) have begun to shed light on the complex microbial populations inhabiting these production systems. Using this multifaceted approach, we have begun to further understand the effects of prolonged treatment with water quality chemistries such as solids control products and the negative effects it can have on a microbial control strategy. In this study, we look at a production system where the application of low-dosage solids control chemistries caused the microbes to become dormant and thus more resistant to biocide treatments which increased the risk of MIC related failures. Furthermore, treatment of these microbes with other solids control chemistries and biocides have revealed a number other of resistance mechanisms suggesting these microbes utilize multiple strategies for survival which may complicate remediation efforts.

Abstract
Getting to know the response of different groups of aquatic organisms tested in altered thermal environments to environmental conditions makes it possible to understand processes of adaptation and limitation factors such as temperature and light. Field sites were located in three thermally abnormal lakes (cooling system of power plants), in eastern part of Wielkopolska region (western Poland): Pątnowskie, Wąsosko-Mikorzyńskie and Licheńskie. Water temperatures of these lakes do not fall below 10°C throughout the year, and the surface water temperature in spring is about 20˚C. In this study, we investigated the species structure of the spring phytoplankton community in a temperature gradient and analyzed diversity of periphyton collected from alien species (Vallisneria spiralis) and stones. 94 taxa belonging to 56 genera of algae (including phytoplankton and periphyton) were determined. The highest number of algae species were observed among Chlorophyta (49), Bacillariophyceae (34) and Cyanobacteria (6). In spite of important differences in temperature in the investigated lakes, taxonomic composition of phytoplankton was comparable. Thermophilic species: Glochidinium penardiforme and Cylindrospermopsis raciborskii were found in the species structure (blooms were not observed). The obtained data also showed that the biotic surface of Vallisneria spiralis was a better substrate for Bacillariophyceae colonization than stones. The examination in the spring season of these thermally altered lakes, indicated the taxonomic composition of phytoplankton typical for eutrophic reservoirs (not heated). There was no replacement of any phytoplankton groups which are characteristic for spring conditions, even if there were changes in the competition dynamics.

Published: May 2015

Abstract
Cypripedium calceolus is considered an endangered species in the territory of Poland. Population of this rare species, situated at Lake Kwiecko (Western Pomerania), was regularly monitored in the years 1986-2013. The studied population has been under the permanent influence of the nearby hydroelectric power plant for almost 45 years. The field observations showed that the power plant had no negative impact on the condition of Cypripedium calceolus population. An indication of its good condition was, among others, an increase in the size - from 150 to 350 specimens within the study period.

Background The relationship between orbit and maxillary sinus volumes in patients with chronic maxillary atelectasis (CMA), commonly known as silent sinus syndrome if enophthalmos is present, is poorly understood. Methods A retrospective review of 22 patients who underwent endoscopic sinus surgery (ESS) for CMA from 2005 to 2013 was performed. Computed tomography (CT) images were analyzed using OsiriX 5.8.2 software for volumetric analysis of the orbit and maxillary sinus at presentation and after surgical treatment with ESS. Results Pretreatment mean orbit volumes on the diseased side (DS) and the contralateral side (CS) were 29.22 and 26.50 mL, respectively (p < 0.001); mean sinus volumes on the DS and CS were 8.51 and 17.20 mL, respectively (p < 0.001); and pretreatment mean midorbit heights (MOHs) on the DS and CS were 3.39 cm and 3.07 cm, respectively (p < 0.001). The percent decrease in sinus volume on the DS compared to that on the CS did not correlate significantly with the percent orbit-volume increase. Enophthalmos was present in nine (41%) patients, and diplopia was present in three (14%) patients. The measured degree of increased orbit volume and decreased sinus volume secondary to CMA did not significantly predict the presence of enophthalmos at presentation. Seven patients underwent sinus CT more than 6 months after ESS. In these patients, orbit volume on the DS decreased from 29.67 to 27.52 mL (p = 0.005), and sinus volume on the DS increased from 9.78 to 11.84 mL (p = 0.08). Conclusions Volumetric analysis is a powerful and novel method for objectively demonstrating the degree of orbit expansion and maxillary sinus contraction seen with CMA. Spontaneous maxillary sinus expansion and a decrease in orbit volume can occur after ESS, but post-ESS volumes do not return to the normal volume of the CS.

Published: May 2015

Background A cerebrospinal fluid (CSF) leak, commonly presenting as rhinorrhea, is a well-recognized complication of lateral skull base surgery. Failure of conservative treatment measures in these cases necessitates surgical intervention. Objective Our aim is to demonstrate that endoscopic endonasal closure of the eustachian tube is a reasonable alternative to more traditional techniques for management of recalcitrant postoperative CSF rhinorrhea after removal of middle and posterior cranial fossa lesions. Methods A retrospective chart review was performed for patients who presented with CSF rhinorrhea after lateral skull base surgery at a tertiary medical center over a 17-year period, from 1997 to 2014. Nine patients managed with endoscopic endonasal closure of the eustachian tube were evaluated for preoperative hearing status, approach to lateral skull base surgery, pathology, size and location of the tumor, timing and presentation of CSF leak, methods of treatment, length of hospital stay, complications, and success of the procedure. Results Of the nine patients included in this review, seven were managed successfully with endoscopic endonasal eustachian tube closure. Of those seven, one required a revision procedure. Average length of postoperative stay was 5.8 days. There were no major complications. Follow up of greater than 100 months has been achieved since the first procedure. Conclusion Endoscopic endonasal eustachian tube closure is a safe, minimally invasive and effective method for obliteration of the eustachian tube orifice. The algorithm for management of recalcitrant postoperative CSF rhinorrhea after lateral skull base surgery should include endoscopic endonasal closure of the eustachian tube.

Background Granulomatosis with polyangiitis (GPA) is an autoimmune disease characterized by necrotizing granulomatous airway inflammation and vasculitis. Sinonasal involvement occurs in more than 80% cases, with antineutrophil cytoplasmic antibody (C-ANCA) titers used as a marker of disease severity. The purpose of this study was to determine whether C-ANCA levels impact radiographic findings and healthcare use in patients with sinonasal GPA. Methods A retrospective review was performed on GPA patients evaluated in a multidisciplinary rheumatologic/otolaryngologic clinic from 2008 to 2013. Data were collected with respect to age, gender, clinical presentation, C-ANCA titers, Lund-Mackay (LM) scores, surgical interventions, and healthcare use, the latter of which were determined by assessing the number of rheumatology/otolaryngology clinic visits, computed tomography (CT) scans, and email/telephone encounters. Results A total of 44 patients were identified, 11 male and 33 female. Sinonasal manifestations were evident in 70.4%, with chronic rhinosinusitis (CRS) (41.9%), septal perforation (38.7%), and crusting (32.2%) the most common findings. No significant differences in number of CT scans (p = 0.10) or mean LM scores (p = 0.47) were found between patients with more than or equal to 1:80 and less than 1:80 C-ANCA titers, respectively. However, overall healthcare use was increased in the more than or equal to 1:80 C-ANCA group (n = 28) compared with less than 1:80 (n = 16), with a significantly greater number of rheumatologic/otolaryngologic encounters (mean 121 versus 69.2, p = 0.03) noted. When otolaryngologic healthcare use was specifically examined, the average number of encounters was also higher in more than or equal to 1:80 C-ANCA patients (31.9 versus 22.9), but this difference was not statistically significant (p = 0.16). Conclusion Sinonasal GPA patients with presenting C-ANCA titers more than or equal to 1:80 demonstrated significantly greater overall healthcare use than their lower C-ANCA level counterparts (less than 1:80). However, no significant differences in otolaryngology resource use or LM scores were evident between the two titer groups.

Background Major histocompatibility complex (MHC) class II is involved in T-cell activation, cytokine secretion, and induction of immune responses. Cytokines, staphylococcus super antigens, and eosinophil activation are proposed to play important roles in aspirin-exacerbated respiratory disease (AERD). Objectives This study is aimed at investigating the association of HLA-DRB and DQ genetic variabilities in patients with AERD. Methods A genetic association analysis in three different groups, including 33 patients with AERD, 17 patients with aspirin-tolerant asthma (ATA), and 100 healthy controls was performed. Oral aspirin challenge (OAC) test was performed to identify aspirin hypersensitivity. Pulmonary function test (PFT) was performed for all patients. Eosinophil percentage in nasal smear and peripheral blood and serum immunoglobin (Ig)E were investigated. HLA-DRB, HLA-DQA1, and HLA-DQB1 were genotyped using polymerase chain reaction. Results HLA-DQB1*0302 (OR, 5.49, 95% confidence interval [CI],(2.40-12.59)), HLA-DQA1*0301 (OR, 2.90, 95%CI,(1.49-5.67)), HLA-DRB4 (OR, 2.94, 95%CI,(1.61-5.36)), and HLA-DRB1*04 (OR, 3.19, 95%CI,(1.57-6.47)) were higher in patients with AERD compared with controls. In patients with AERD, HLA-DQB1*0301 (OR,0.22, 95%CI,(0.09-0.54)), HLA-DQA1*0501 (OR, 0.42, 95%CI, (0.21-0.81)), HLA-DRB1*11 (OR, 0.30, 95%CI,(0.12-0.73)), and HLA-DRB3 (OR, 0.38, 95%CI,(0.21-0.70)) were significantly lower compared with healthy controls. Patients with AERD had lower frequencies of HLA-DQB1*0301 (OR, 0.27, 95%CI,(0.08-0.86)), and HLA-DRB1*011 (OR, 0.27, 95%CI,(0.08-0.86)) compared with ATA. Haplotypes of HLA-DRB1*04/DQA1*0301/DQB1*0302 (OR, 4.25, 95%CI,(1.94-9.29)) and HLA-DRB1*07 /DQA1*0201/ DQB1*0201 (OR, 3.52, 95%CI,(1.54-8.06)) were higher in patients with AERD compared with controls (all p < 0.05). Conclusions Results of this study suggest that HLA-DQB1*0302 and HLA-DRB1*04 and their related haplotypes are genes involved in predisposing patients to AERD, whereas HLA-DQB1*0301 and HLA-DRB1*011 have negative association with AERD.
Radiofrequency Ablation for Treatment of Hereditary Hemorrhagic Telangiectasia Lesions: “How I do it”
Authors: Rotenberg Brian , Noyek Samantha , Chin Christopher J. 
Published: May 2015

Introduction Hereditary hemorrhagic telangiectasia (HHT) can cause significant epistaxis for those that suffer from it. Traditaional surgical treatments are ablative and can cause thermal damage. Radiofrequency (RF) energy can potentially be used to ablate HHT plaques at a lower temperature. In this article we describe our use of RF energy to treat HHT. Methods A Coblation Evac70 wand was used with patients under general anesthetic to ablate visible lesions. The surgical technique is described in detail. Results Thirty-seven patients have been treated over a 3-year time span showing significant improvement in epistaxis severity as measured by the Epistaxis Severity Score. There were three septal perforations that developed, but these were all in patients who had undergone several prior septal cauteries. Conclusion RF energy via Coblation is an effective and safe means of surgically treating HHT lesions, with good epistaxis severity improvement and minimal patient morbidity.

Published: May 2015

Background There have been few comparative studies on olfactory function and sinonasal-specific quality of life (QOL) after endoscopic or microscopic surgery using a transsphenoidal approach (TSA). Methods A retrospective review of a prospectively collected database was performed. Thirty-five patients who underwent a transnasal endoscopic approach and 20 patients who underwent a transnasal transseptal microscopic approach for treatment of pituitary adenoma were evaluated. An anterior skull base (ASK) nasal inventory and a subjective visual analog scale (VAS) (0-100) for olfaction were evaluated before and at one and three months after surgery. A cross-cultural smell identification test (CC-SIT) and a butanol threshold test (BTT) were also measured before and three months after surgery. Results There was no significant difference in subjective olfaction or CC-SIT or BTT score between the endoscopic and microscopic groups. The microscopic group (11.35 ± 3.67 and 9.72 ± 2.54, respectively) showed better ASK nasal inventory outcomes at one and three months after surgery compared with the endoscopic group (14.00 ± 4.85 and 11.70 ± 3.28, respectively; p = 0.029 and 0.036, respectively) especially in the subdomains of “nasal crusting” and “urge to blow nose.” Conclusion Transnasal transseptal microscopic pituitary surgery confers a better early postoperative sinonasal QOL with a comparable olfactory outcome compared with the endoscopic approach. Although many believe that an endoscopic approach is less invasive, preservation of the sinonasal mucosa proves to be more important in terms of sinonasal QOL than use of an endoscope or microscope.

Published: May 2015

Background An increased coexistence of gastroesophageal reflux disease (GERD) and chronic rhinosinusitis (CRS) has been reported in epidemiologic and register studies, and reflux has been shown more frequently in patients with CRS in studies using esophagus pH manometry compared to participants without CRS. A discussion is ongoing about whether there might be an association between these two diseases and, if so, whether the association is causal. Objective The purpose of this study was to clinically investigate the prevalence and symptom severity scores of CRS among patients with GERD. The results were compared with those of a randomly assigned control group from the general Danish population. Method In this case–control study, 82 patients with GERD were examined for CRS using the European Position Paper on Rhinosinusitis and Nasal Polyps criteria, which combine patient history and anterior/posterior rhinoscopy results. Sinonasal-related quality of life was assessed by using the Sino-Nasal Outcome Test 22 (SNOT-22). These results were compared with those of a population-based control group examined for CRS in the same way. Results The prevalence of CRS among patients with GERD was 20.7% (95% confidence interval [CI], 12.0%-29.5%), significantly higher than the CRS prevalence of 8.5% (95% CI, 6.8%-10.2%) in the background population. Patients with GERD and CRS had an average SNOT-22 score of 43.8, whereas patients with CRS from the background population scored, on average, 28.1. Having GERD increased the mean SNOT-22 score in patients with CRS by 15.7 (95% CI, 6.5-24.9). Conclusion The results of this study provide additional evidence of an association between GERD and CRS and indicate that GERD may play a role in the development of CRS. The results also show that sinonasal-related quality of life is decreased in patients with CRS who also suffer from GERD.

Published: May 2015

Background Allergic rhinitis (AR) is an allergic inflammatory disease induced by various mediators released by infiltrating inflammatory cells. Vascular endothelial growth factor (VEGF) increases the airway inflammatory response by promoting vascular permeability. Furthermore, it is known that Allium hookeri and one of its constituent compounds, rutin (RU), have anti-inflammatory, antioxidant, and antiplatelet effects. Objective The aim of this study was to evaluate the regulation of AR by RU and A. hookeri. Methods We assessed the therapeutic effects and the regulatory mechanisms of A. hookeri and RU on phorbol 12-myristate 13-acetate plus A23187 (PMACI) stimulated human mast cell line (HMC) 1 cells, and ovalbumin (OVA) sensitized mouse model of AR. Results A. hookeri and RU significantly inhibited the production and messenger RNA (mRNA) expression of VEGF in PMACI-stimulated HMC-1 cells and significantly decreased VEGF levels in our murine AR model. The increased rubs scores and immunoglobulin E and interleukin (IL) 4 levels in OVA-sensitized mice were significantly reduced by the administration of A. hookeri, and RU significantly inhibited the production and mRNA expression and RU. Also, A. hookeri and RU significantly reduced IL-4 and IL-5 production in OVA-stimulated splenocytes. Furthermore, A. hookeri and RU significantly decreased chemokine levels (intercellular adhesion molecule-1, macrophage inflammatory protein-2) in nasal mucosa tissues. In the mouse AR model, A. hookeri and RU significantly prevented eosinophil and mast cell infiltration and reduced inflammatory cytokine levels induced by OVA sensitization. In addition, A. hookeri and RU significantly reduced mast cell-derived caspase-1 activity in OVA-sensitized mice. Conclusion The present study showed that A. hookeri or RU had an anti-allergic inflammatory effects. Analysis of these results indicated that A. hookeri and RU might protect against AR.
Psychologie sociale du travail : rencontres entre recherche et intervention

Published: May 2015

L’objectif de cet article est de présenter la perspective de la psychologie sociale du travail (PST) et les rapports qu’elle établit entre recherche et intervention. La PST, de notre point de vue, est issue des réponses aux problèmes sociaux et économiques auxquels font face les travailleurs. Dans le cas du Brésil, elle se développe à partir d’une psychologie sociale critique et prend particulièrement corps dans deux domaines : la santé du travailleur et l’économie solidaire. Du fait qu’elle s’insère dans des débats publics et aborde des problèmes socialement importants, s’établit un rapport dynamique et imprévisible entre recherche et intervention, en PST, directement dans le champ où les demandes sociales surviennent.

Published: May 2015

À partir de deux recherches, utilisant des ateliers comme dispositifs d’intervention, cet article vise la problématisation de certains des principaux défis soulevés par l’expérience sur le terrain. Pour analyser les tensions éventuelles et les contributions de la recherche-intervention, les auteurs examinent les impasses survenues à trois moments distincts de la recherche : les négociations entre les partenaires au début d’une recherche-intervention, les processus de finalisation des actions prévues et les écrits issus de cette expérience. L’objectif est d’articuler ces sujets avec la réflexion sur la pratique éthique d’un faire partagé et la circulation des connaissances produites. Le versant créatif de cette perspective porte sur la reprise et la mise en œuvre de modèles théorico-méthodologiques conçus dans d’autres contextes pour produire de nouvelles pratiques de connaissances dans des actions situées.
