PTSD Symptoms Mediate the Effect of Attachment on Pain and Somatisation after Whiplash Injury
Authors: Andersen Tonny Elmose , Elklit Ask , Brink Ole 
Published: May 2013

Introduction:The development of persistent pain post-whiplash injury is still an unresolved mystery despite the fact that approximately 50% of individuals reporting whiplash develop persistent pain. There is agreement that high initial pain and PTSD symptoms are indicators of a poor prognosis after whiplash injury. Recently attachment insecurity has been proposed as a vulnerability factor for both pain and PTSD. In order to guide treatment it is important to examine possible mechanisms which may cause persistent pain and medically unexplained symptoms after a whiplash injury.Aim:The present study examines attachment insecurity and PTSD symptoms as possible vulnerability factors in relation to high levels of pain and somatisation after sub-acute whiplash injury.Methods:Data were collected from 327 patients (women = 204) referred consecutively to the emergency unit after acute whiplash injury. Within 1-month post injury, patients answered a questionnaire regarding attachment insecurity, pain, somatisation, and PTSD symptoms. Multiple mediation analyses were performed to assess whether the PTSD symptom clusters mediated the association between attachment insecurity, pain, and somatisation.Results:A total of 15% fulfilled the DSM-IV symptom cluster criteria for a possible PTSD diagnosis and 11.6% fulfilled the criteria for somatisation. PTSD increased the likelihood of belonging to the moderate-severe pain group three-fold. In relation to somatisation the likelihood of belonging to the group was almost increased four-fold. The PTSD symptom clusters of avoidance and hyperarousal mediated the association between the attachment dimensions, pain, and somatisation.Conclusion:Acknowledging that PTSD is part of the aetiology involved in explaining persistent symptoms after whiplash, may help sufferers to gain early and more suited treatment, which in turn may prevent the condition from becoming chronic.
Toward an Understanding of Tropical Cyclone Formation with a Nonhydrostatic, Mesoscale-Convection-Resolving Model§
Authors: Yamasaki Masanori 
Published: May 2013

This paper describes results from numerical experiments which have been made toward a better understanding
of tropical cyclone formation. This study uses a nonhydrostatic version of the author’s mesoscale-convection-resolving
model that was developed in the 1980s to improve paramerization schemes of moist convection. In this study the
horizontal grid size is taken to be 20 km in an area of 6,000 km x 3,000 km, and a non-uniform coarse grid is used in two
areas to its north and south.
Results from two numerical experiments are presented; one (case 1) without any environmental flow, and the other (case
2) with an easterly flow without low-level vertical shear. Three circular buoyancy perturbations are placed in the west-east
direction at the initial time. Convection is initiated in the imposed latently unstable (positive CAPE) area. In both cases, a
vortex with a pressure low is formed, and two band-shaped convective systems are formed to the north and the south of
the vortex center. The vortex and two convective systems are oriented in the westsouthwest – eastnortheast direction, and
their horizontal scales are nearly 2,000 km.
In case 1, the band-shaped convective system on the southern side is stronger, and winds are stronger just to its south. In
contrast, in case 2, the northern convective system is stronger, and winds are stronger just to its north. Therefore, the
distributions of the equivalent potential temperature in the boundary layer and latent instability (positive buoyancy of the
rising air) are also quite different between cases 1 and 2. The TC formation processes in these different cases are
discussed, with an emphasis on the importance of examining the time change of latent instability field.
The Formation of the Genre System on Norwegian Broadcast Radio
Authors: Vagle Wenche 
Published: May 2013

Abstract
This article deals with the formation and first development of the radio genre system in Norway in the interwar years (1925-1940). It is shown that the programmes of the 1920s were mostly imperfect reproductions of existent cultural forms. Yet, a beginning modernization of the genre repertoire took place in the 1930s. Whereas the rudimentary genre repertoire of the 1920s was built up through a plain copying from other domains in society, the latter half of the 1930s saw the introduction of a more advanced genre-generating process whereby new genres were formed through a mixing of two or more existing norms. This article also identifies a number of developmental trends that had their slow start in the 1920s and would mark the evolution of Norwegian radio’s registers and genres ever since.

Authors: Kang Shuai , Yang You-Chang , He Juan , Xiong Fei-Qiao , Xu Ning 
Published: May 2013

Abstract
The ground state energy, some low-lying excited state energies and oscillator strengths for a hydrogen atom confined in both a Debye screening potential and finite impenetrable spherical box have been calculated. These have been calculated using a linear variational method based on B-spline basis functions. The results have been compared with those of other authors. The evaluated energies and oscillator strengths with respect to different plasma screening parameters with a certain confinement radii are discussed.

Published: May 2013

Abstract
In this work we extend our previous results and derive an expansion formula for fractional derivatives of variable order. The formula is used to determine fractional derivatives of variable order of two elementary functions. Also we propose a constitutive equation describing a solidifying material and determine the corresponding stress relaxation function.
Fatal bupivacaine overdose through intrathecally positioned epidural catheter
Authors: Davies Forsman Lina , Öström Mats , Svanström Mikael , Eriksson Anders 
Published: May 2013

ABSTRACT
We describe a fatality due to an intrathecally positioned epidural catheter and an infusion rate of bupivacaine set 10 times higher than planned. The undetected misplacement, despite safety routines, is discussed along with the toxicological findings and new information on the intrathecal distribution of bupivacaine. From a clinical point of view, the human factor, in combination with an indistinct decimal point on the pump, was considered as the reason for the unfortunate overdose. In continuous epidural infusion of local anesthetics, the importance of guidelines and informed staff in managing complications of epidural lumbar infusion as well as careful monitoring of the vital functions is essential. Guidelines are also vital during the procedure of insertion of epidural catheters. When using combined spinal and epidural anaesthesia, we believe that an epidural catheter should be inserted, and its position tested, prior to spinal anesthesia. The case also illustrates the need of innovative investigation techniques to confirm the suspicion of unusual manifestations of inadvertent drug effects. Segmental analysis, together with analyses in a control case, enabled us to elucidate the high and varying tissue concentrations in the central nervous system.

Published: May 2013

Currently there is an increasing interest in application of natural clay minerals in production of various products, including sorbents for waste water treatment. For practical application of clay as a sorbent, it is significant not only to establish its properties, but also to be able to modify them. Only during the last twenty years, an increasing effort has been directed to systematic studies of clay sorption properties. A special attention has been devoted to improvement of clay sorption properties, which could allow to scientifically develop various sorbents for collection of oil products, such as oil spills from water surface, water processing and cleaning of waste waters from heavy metal ions, organic and inorganic admixtures, etc.
In this study, surface properties of Latvian Triassic (Vadakste deposit) smectite-containing clay samples were examined, in order to develop cheap, clay-based sorbents of high quality. Using sedimentation method, the granulometric composition of natural clay samples was determined. Surface morphology of the obtained samples was studied by using scanning electron microscopy. Sorption properties of natural Vadakste deposit clay samples were modified by thermal treatment, as well as by adding a natural modifier based on hemicellulose and lignin (HLS). This type of clay modification has almost never been used in practice. Optimal thermal treatment conditions and HLS modification conditions were determined for the natural clay samples. It was found that water absorption decreased with increasing the thermal treatment temperature from 300 to 500 and 800 °C, however silicone oil and rapeseed oil absorption doubled at the same time. After adding HLS to clays within the range of 0.053% to 0.13%, both water and oil absorption doubled. The ability of natural and modified clay samples to adsorb copper and zinc ions from the corresponding salt solutions was investigated. The obtained results proved that the developed clay-based sorbent granules can be used for removal of copper and zinc ions from waste water, for collection of oil and oily substances; and as a cheap, environmentally safe pet litter.
Collective self-reliance: A portrait of a Yugoslav development strategy
Authors: Pierzyńska Justyna 
Published: May 2013

Abstract
Collective self-reliance is an interesting, nowadays forgotten development
strategy that was popular between the 1950s and 1970s, particularly
among the newly independent states of the “Third World”. It was widely
discussed in the 1960s, 1970s and 1980s by Yugoslav researchers,
among others. This paper aims to examine Yugoslav ideas on collective
self-reliance from a historical perspective on the basis of original works
from the time. It presents a brief history of the idea and its resonance in the
non-aligned world, contemporary criticism, as well as political, economic
and spatial dimensions of the strategy and the means by which it aims
to achieve the goal of an economically independent, sovereign “Third
World region”. A summary of basic contrasts between two interpretations
of collective self-reliance is given to illustrate the specifics of the Yugoslav
approach. This developed strategy serves as a theoretical impulse to
reintroduce the ideas of south-south cooperation to the development
discourse.

Published: May 2013

Abstract In this paper, we describe a new method for constructing a tubular surface surrounding a timelike biharmonic curve in the Lorentzian Heisenberg group Heis3. Firstly, we characterize timelike biharmonic curves in terms of their curvature and torsion. Also, by using timelike biharmonic curves, we give explicit parametrizations of tubular surfaces in the Lorentzian Heisenberg group Heis3.

Authors: Kim Young Hyo , Park Chang-Shin , Lim Dae Hyun , Son Byong Kwan , Kim Jeong Hee , Ahn Sung-Hye , Bochner Bruce S. , Na Kwangmin , Jang Tae Young 
Published: May 2013

Background Sialic acid-binding Ig-like lectin-F (Siglec-F) in mice and its functional paralog Siglec-8 in humans are transmembrane receptors that play a role in the apoptosis of eosinophils. We aimed to evaluate the therapeutic potential of anti-Siglec-F antibodies in a murine model of allergic rhinitis. Methods Twenty-eight BALB/c mice were used. In group A (control group, n = 7), mice were sensitized and challenged with saline. In group B (ovalbumin [OVA] challenge group, n = 7), OVA was used for i.p. sensitization and intranasal challenge. Mice in group C (control IgG group, n = 7) or those in group D (anti-Siglec-F group, n = 7) had been given rabbit control IgG or anti-Siglec-F antibody injections, respectively. We assessed the number of nose-scratching events; serum total/OVA-specific IgE; the number of eosinophils, neutrophils, and lymphocytes in bronchoalveolar lavage (BAL) fluid; histopathological changes in nasal cavity tissues; and the levels of IL-4, IL-5, and IL-13 in BAL fluid. Results Mice in group D had significantly less nose scratching. Serum total and OVA-specific IgE were not significantly changed. The number of eosinophils in BAL fluid and in the lamina propria of the nasal cavity mucosa was significantly decreased with anti-Siglec-F antibody treatment. The levels of Th2 cytokines such as IL-4, IL-5, and IL-13 were also significantly decreased with anti-Siglec-F antibody treatment. Conclusion Anti-Siglec-F antibody has beneficial effects in a mouse model of experimental allergic rhinitis.
Ergonomic Considerations in Endoscopic Sinus Surgery: Lessons Learned from Laparoscopic Surgeons
Authors: Ramakrishnan Vijay R. , Montero Paul N. 
Published: May 2013

Background Endoscopic sinus procedures are increasingly common, and more technically difficult procedures are being undertaken to provide patients with minimally invasive alternatives to traditional open surgical techniques. However, such endoscopic approaches have increasing physical demands on the surgeon. The aim of this review is to summarize current literature on surgical ergonomic principles as they relate to endoscopic sinus and skull base surgery and focus on future needs for our specialty. Methods Literature review was performed of surgical ergonomics and, particularly, laparoscopic ergonomic principles. Results Existing ergonomic principles for laparoscopic surgery can be applied to endoscopic sinus and skull base surgery and can be expected to offer benefits in terms of surgeon fatigue, physical discomfort, and task efficiency. Conclusion Increasing surgeon awareness will allow for many basic ergonomic principles to be applied to endoscopic sinus and skull base surgery. Although many simple changes can be immediately made, there is a clear need for further study and abundant room for innovation.
Neonatal Jaundice is a Risk Factor for Childhood Allergic Rhinitis: A Retrospective Cohort Study
Authors: Sun Hai-Lun , Lue Ko-Huang , Ku Min-Sho 
Published: May 2013

Background This study evaluates the association between neonatal jaundice and childhood allergic rhinitis (AR). Methods Eleven thousand three hundred twenty-eight children were collected from the National Health Insurance Research Database in Taiwan. Their claims data were evaluated from birth to 10 years of age, and they were assigned to either the study (with neonatal jaundice) or the control (without neonatal jaundice) group. The diagnostic criteria for AR were at least three diagnoses of AR at outpatient services, one diagnosis of AR during an admission, or one diagnosis of AR in an emergency department. Mantel-Haenszel odds ratios (ORs) were calculated after adjustment for the following confounders: preterm/low birth weight, neonatal infection, other respiratory conditions, other birth conditions, and gender. AR rate, AR onset time, the use of oral antihistamines/nasal corticosteroids, outpatient visit frequency for AR, lower respiratory infection (LRI) rates, sinusitis/otitis media/conjunctivitis rates, and the effect of phototherapy were evaluated. Results After adjustment for the confounding factors, the rate of AR was higher in icteric children (OR, 1.46; 95% confidence interval, 1.24~1.72). There was a higher incidence of AR in children <4 years old with icterus. The use of oral antihistamines, LRI rates, sinusitis rates, and otitis media rates were higher in the icteric children. There was no association between phototherapy and childhood AR. Conclusion Neonatal jaundice increased the rate and complications of childhood AR in subjects aged up to 10 years and may be a risk factor for childhood AR.
The Role of the Nose in Sleep-disordered Breathing
Authors: Meen Eric K. , Chandra Rakesh K. 
Published: May 2013

Background Sleep-disordered breathing (SDB) is a spectrum of airway collapse, ranging from primary snoring to profound obstructive sleep apnea (OSA). Studies have shown an association between impaired nasal breathing and SDB; consequently, treatments of nasal obstruction are often used in an attempt to improve disease severity. The authors performed a review of the literature to determine the impact of nasal obstruction and the effectiveness of nonsurgical and surgical interventions on SDB. Methods Relevant literature up to 2012 on the association between nasal obstruction and SDB and effectiveness of nonsurgical and surgical treatment of the nose in SDB were reviewed. Results The literature is mostly limited to uncontrolled case series in which patient groups, interventions, disease definitions, and outcome measures are not standardized. Nasal medications, including intranasal steroids and nasal decongestants, have not been shown to improve either snoring or OSA. Nasal dilators have no impact on OSA but may improve snoring. Surgery for nasal obstruction does not improve objective indicators of SDB but can improve subjective elements of disease, such as snoring, sleepiness, and quality of life. Nasal surgery can facilitate continuous positive airway pressure use in cases where nasal obstruction is the factor limiting compliance. Conclusion Nasal obstruction plays a modulating, but not causative, role in SDB. Nasal interventions may improve subjective aspects of snoring and OSA but do not improve objective indicators of disease. Standardization of methods and higher evidence level studies will further clarify the benefit of nasal interventions in the treatment of SDB.

Published: May 2013

Background Numerous studies have examined the relationship of bronchial hyperresponsiveness (BHR) to asthma or allergic rhinitis (AR). However, little is known regarding the association between BHR and nonallergic rhinitis (NAR). This study investigated the prevalence and risk factors of BHR in pediatric patients with rhinitis and analyzed the difference between patients with AR and those with NAR. Methods A total of 227 subjects with rhinitis aged 6–15 years underwent a parental survey and laboratory tests, including skin-prick test and methacholine challenge test. Outcome variables were analyzed in relation to BHR. Results The prevalence of BHR was 55.7 and 25.5% in patients with AR and those with NAR, respectively. The persistency of rhinitis, blood eosinophil count, and baseline lung function were significantly associated with BHR in patients with AR, whereas individual or familial medical history, environmental factors, the serum immunoglobulin E level, the number of sensitized allergens, and the wheal size ratio of allergen to histamine did not affect the BHR rate. In multivariate analysis, the persistency of rhinitis was the only significant predictor of BHR in AR patients. However, persistent rhinitis symptoms did not increase the risk of BHR in NAR patients. Conclusion BHR occurs over two times more frequently in children with AR than in those with NAR. In addition, persistent nasal inflammation appears to increase the risk of BHR only in the presence of atopy.

Published: May 2013

Background Data on the expression and role of matrix metalloproteinases (MMPs) and their tissue inhibitors (tissue inhibitor of metalloproteinases [TIMPs]) in chronic rhinosinusitis with nasal polyps (CRSwNPs) are contradictory, partly because or the use of different techniques of tissue analysis. The aim of this study was to establish a qualitative/semiquantitative method of analysis on the expression of these remodeling markers in different tissue structures and eosinophils in both NPs and nasal mucosa (NM). Methods NP tissues were obtained from patients undergoing endoscopic sinus surgery for severe CRSwNPs (n = 33) and NM tissues from patients undergoing nasal corrective surgery (n = 12). MMPs (MMP-1, MMP-2, MMP-7, and MMP-9) and TIMP type 1 (TIMP-1) expression were evaluated by immunohistochemistry in tissue structures (epithelium, glands, vessels, and extracellular matrix [ECM]) and eosinophils. Tissue eosinophilia was also analyzed in NP tissues. Results MMPs and TIMP-1 expression were found in the epithelium, glands, vessels, and ECM (in both NM and NP) and in eosinophils (only in NP). Significant (p < 0.01) findings were observed in NP compared with NM: increase in MMP-1 in ECM; decrease in MMP-2 in glands, vessels, and epithelium; decrease in MMP-7 in all tissue structures; increase in MMP-9 in ECM and decrease in epithelium and glands; and no differences in TIMP-1. NP tissues showed a clear eosinophilic inflammation compared with NM (p < 0.01). Conclusion These findings suggest that (1) metalloproteases (MMP-1, MMP-2, MMP-7, and MMP-9) may play an important role in the remodeling of NPs and/or in NP formation and (2) a differential analysis of tissue structures and inflammatory cells should be performed when studying remodeling marker expression and regulation in the upper airways.
