Consistent Technique Limits Suspension Laryngoscopy Complications
ntroductionâSuspension laryngoscopy (SL) is a commonly performed procedure among otolaryngologists. Several studies have shown that adverse effects occur regularly with SL.
ObjectiveâTo evaluate the postoperative complications of SL, and to determine if protecting the dentition and the oral mucosa and limiting suspension times decrease the overall incidence of oral cavity and pharyngeal complications of SL.
MethodsâAll of the cases of SL performed by 1 surgeon from November 2008 through September 2014 were retrospectively reviewed. A consistent technique for dental and mucosal protection was utilized, and suspension times were strictly limited to 30 consecutive minutes. The incidence of postoperative complications was calculated and analyzed with respect to gender, smoking status, dentition, laryngoscope type, and suspension system.
ResultsâA total of 213 consecutive SL cases were reviewed, including 174 patients (94 male, 80 female). The overall postoperative complication rate was of 3.8%. Four patients experienced tongue-related complications, two experienced oral mucosal alterations, one had a dental injury, and one experienced a minor facial burn. The complication incidence was greater with the Zeitels system (12.5%) compared with the Lewy suspension system (3.3%), although it was not significant (pâ=â0.4). Likewise, the association of complications with other patient factors was not statistically significant.
ConclusionâOnly 8 out of 213 cases in the present series experienced complications, which is significantly less than the complication rates observed in other reports. Consistent and conscientious protection of the dentition and of the oral mucosa and limiting suspension times to 30 minutes are factors unique to our series that appear to reduce complications in endolaryngeal surgery
Thinking beyond the hybrid:âactually-existingâ cities âafter neoliberalismâ in Boyle <i>et al.</i>
In their article, âThe spatialities of actually existing neoliberalism in Glasgow, 1977 to presentâ, Mark Boyle, Christopher McWilliams and Gareth Rice (2008) usefully problematise our current understanding of neoliberal urbanism. Our response is aimed at developing a sympathetic but critical approach to Boyle et al's understanding of neoliberal urbanism as illustrated by the Glasgow example. In particular, the counterposing by Boyle et al of a 'hybrid, mutant' model to a 'pure' model of neoliberalism for us misrepresents existing models of neoliberalism as a perfectly finished object rather than a roughly mottled process. That they do not identify any âpureâ model leads them to create a straw construct against which they can claim a more sophisticated, refined approach to the messiness of neoliberal urbanism. In contrast, we view neoliberalism as a contested and unstable response to accumulation crises at various scales of analysis
Prolactin activates the interferon-regulated p91 transcription factor and the Jak2 kinase by tyrosine phosphorylation.
Asterixis.
Adams and Foley described asterixis in the 1940s in patients with hepatic encephalopathy, but it has since been associated with a wide range of potential causes, both in neurology and general medicine. Here, we review the history, characteristics and clinical significance of this important clinical sign
Opportunities for topical antimicrobial therapy: permeation of canine skin by fusidic acid
BACKGROUND: Staphylococcal infection of the canine epidermis and hair follicle is amongst the commonest reasons for antimicrobial prescribing in small animal veterinary practice. Topical therapy with fusidic acid (FA) is an attractive alternative to systemic therapy based on low minimum inhibitory concentrations (MICs, commonly <0.03 mg/l) documented in canine pathogenic staphylococci, including strains of MRSA and MRSP (methicillin-resistant Staphylococcus aureus and S. pseudintermedius). However, permeation of canine skin by FA has not been evaluated in detail. This study aimed to define the degree and extent of FA permeation in canine skin in vitro from two sites with different hair follicle density following application of a licensed ophthalmic formulation that shares the same vehicle as an FA-betamethasone combination product approved for dermal application in dogs. Topical FA application was modelled using skin held in Franz-type diffusion cells. Concentrations of FA in surface swabs, receptor fluid, and transverse skin sections of defined anatomical depth were determined using high-performance liquid chromatography and ultraviolet (HPLC-UV) analysis. RESULTS: The majority of FA was recovered by surface swabs after 24 h, as expected (meanâ±âSEM: 76.0â±â17.0%). FA was detected within 424/470 (90%) groups of serial sections of transversely cryotomed skin containing follicular infundibula, but never in 48/48 (100%) groups of sections containing only deeper follicular structures, nor in receptor fluid, suggesting that FA does not permeate beyond the infundibulum. The FA concentration (meanâ±âSEM) in the most superficial 240 Όm of skin was 2000â±â815 Όg/g. CONCLUSIONS: Topically applied FA can greatly exceed MICs for canine pathogenic staphylococci at the most common sites of infection. Topical FA therapy should now be evaluated using available formulations in vivo as an alternative to systemic therapy for canine superficial bacterial folliculitis.Peer reviewedFinal Published versio
The open source guild: creating more sustainable enterprise?
© 2017, © Emerald Publishing Limited. Purpose: The purpose of this paper is to report on an action research project with two emergent micro-businesses that explored how their business model connected with the principles of open source. Design/methodology/approach: The authors first gained initial qualitative data to establish the core values of each micro-business, which the authors then explored in the context of open source and business models in two design workshops with each organisation. Findings: The authors developed the open source guild business model, which has the elements of: building a focal micro-business with resources secured through the guild, promoting learning and development through apprenticeship, promoting shared values through a commons of experience and capturing value by protecting key intellectual property. Research limitations/implications: This research was undertaken with two emergent micro-businesses in the North West of England. Further research will be needed to establish the wider applicability of the open source guild model. Practical implications: The open source guild model can be a mechanism for an emergent micro-business to create a community around their values and grow their business without conventional external investment of resources. Originality/value: This research contributes to the literature on business models based on open source and how these models can be sustainable in terms of the quadruple bottom line, which extends the triple bottom line to include personal values and meaning
Characteristics of individuals presenting to treatment for primary alcohol problems versus other drug problems in the Australian patient pathways study
Background: People seeking treatment for substance use disorders often have additional health and social issues.
Although individuals presenting with alcohol as the primary drug of concern (PDOC) account for nearly half of all
treatment episodes to the Australian alcohol and other drug (AOD) service system, previous treatment cohort
studies have focused only on the profile of Australian heroin or methamphetamine users. While studies overseas
indicate that clients seeking treatment primarily for their drinking are less likely to experience social and economic
marginalisation than those seeking treatment primarily for illicit or pharmaceutical drug use, very little research has
directly compared individuals presenting with alcohol as the PDOC to those primarily presenting with other drugs
as their PDOC.
Methods: Seven hundred and ninety-six participants were recruited at entry to specialist AOD treatment in Victoria
and Western Australia, and completed measures of demographic and social factors, substance use, quality of life,
service use, and criminal justice involvement. We compared those with alcohol as their PDOC to those with other
drugs as their PDOC using Pearson chi-square and MannâWhitney U tests.
Results: Rates of social disadvantage, poor quality of life, high severity of substance dependence, and past-year
AOD, mental health, acute health, and social service use were high in all groups. However, participants with alcohol as
the PDOC were older; more likely to have an educational qualification; less likely to report criminal justice involvement,
housing/homelessness service use, tobacco smoking, or problems with multiple substances; and reported better
environmental quality of life; but were more likely to have used ambulance services, than those with other drugs
as their PDOC.
Conclusions: While those seeking treatment primarily for alcohol problems appear less likely to suffer some forms of
social and economic disadvantage or to use multiple substances than those with a primary drug problem, they
experience similarly high levels of substance dependence severity and mental health and AOD service use. These
findings reinforce the need for AOD services to integrate or coordinate care with programs that address the many
complexities clients frequently present with, while also acknowledging differences between those seeking treatment
for alcohol versus other drug problems
Creating citizen-consumers? Public service reform and (un)willing selves
About the book: Postmodern theories heralded the "death of the subject", and thereby deeply contested our intuition that we are free and willing selves. In recent times, the (free) will has come under attack yet again. Findings from the neuro- and cognitive sciences claim the concept of will to be scientifically untenable, specifying that it is our brain rather than our 'self' which decides what we want to do. In spite of these challenges however, the willing self has come to take centre stage in our society: juridical and moral practices ascribing guilt, or the organization of everyday life attributing responsibilities, for instance, can hardly be understood without taking recourse to the willing subject.
In this vein, the authors address topics such as the genealogy of the concept of willing selves, the discourse on agency in neuroscience and sociology, the political debate on volition within neoliberal and neoconservative regimes, approaches toward novel forms of relational responsibility as well as moral evaluations in conceptualizing autonomy
MicroRNA Expression Profiling in Mild Asthmatic Human Airways and Effect of Corticosteroid Therapy
BACKGROUND: Asthma is a common disease characterised by reversible airflow obstruction, bronchial hyperresponsiveness and chronic inflammation, which is commonly treated using corticosteroids such as budesonide. MicroRNAs (miRNAs) are a recently identified family of non-protein encoding genes that regulate protein translation by a mechanism entitled RNA interference. Previous studies have shown lung-specific miRNA expression profiles, although their importance in regulating gene expression is unresolved. We determined whether miRNA expression was differentially expressed in mild asthma and the effect of corticosteroid treatment. METHODOLOGY/PRINCIPAL FINDINGS: We have examined changes in miRNA using a highly sensitive RT-PCR based approach to measure the expression of 227 miRNAs in airway biopsies obtained from normal and mild asthmatic patients. We have also determined whether the anti-inflammatory action of corticosteroids are mediated through miRNAs by determining the profile of miRNA expression in mild asthmatics, before and following 1 month twice daily treatment with inhaled budesonide. Furthermore, we have analysed the expression of miRNAs from individual cell populations from the airway and lung. We found no significant difference in the expression of 227 miRNAs in the airway biopsies obtained from normal and mild asthmatic patients. In addition, despite improved lung function, we found no significant difference in the miRNA expression following one month treatment with the corticosteroid, budesonide. However, analysis of bronchial and alveolar epithelial cells, airway smooth muscle cells, alveolar macrophages and lung fibroblasts demonstrate a miRNA expression profile that is specific to individual cell types and demonstrates the complex cellular heterogeneity within whole tissue samples. CONCLUSIONS: Changes in miRNA expression do not appear to be involved in the development of a mild asthmatic phenotype or in the anti-inflammatory action of the corticosteroid budesonid
Remote control of glucose homeostasis in vivo using photopharmacology
Photopharmacology describes the use of light to precisely deliver drug activity in space and time. Such approaches promise to improve drug specificity by reducing off-target effects. As a proof-of-concept, we have subjected the fourth generation photoswitchable sulfonylurea JB253 to comprehensive toxicology assessment, including mutagenicity and maximum/repeated tolerated dose studies, as well as in vivo testing in rodents. Here, we show that JB253 is well-tolerated with minimal mutagenicity and can be used to optically-control glucose homeostasis in anesthetized mice following delivery of blue light to the pancreas. These studies provide the first demonstration that photopharmacology may one day be applicable to the light-guided treatment of type 2 diabetes and other metabolic disease states in vivo in humans
