Dynamic Modeling and Analysis of a Rotating Piezoelectric Smart Beam
Authors: Lu En , Li Wei , Yang Xuefeng , Wang Yuqiao , Liu Yufei
Published: March 2017

In active vibration control study, piezoelectric actuators and sensors are bonded on the surface of a beam. They can change the frequency and modal characteristics of the system. This paper presents an analysis of the frequency response to a rotating piezoelectric smart beam. Hamilton’s principle along with the assumed mode method are employed to derive the governing equations of the first-order approximate coupling model for the piezoelectric smart beam. The coupling is taken into account as the second-order coupling effect of the axial elongation caused by the transverse displacement of the beam. Then, the equations are transformed into a dimensionless form after identifying the necessary parameters. The dimensionless natural frequencies of the piezoelectric smart beam corresponding to the bending and stretching vibrations are obtained through a numerical simulation, with comparison made of those of the beam with no actuator or sensor. Furthermore, the implication is investigated of the structural parameters and bond location on the piezoelectric actuators and sensors. Besides, the common case of a smart beam bonded with multiple pairs of piezoelectric actuators and sensors is studied, and the effects of the first natural frequency and tip deformation are analyzed. The research provides a theoretical reference for the optimization of structural parameters and location of piezoelectric actuators and sensors, thereby preventing the resonance when the excitation frequency is approximately equal to the natural frequency of the beam.

Here we show that the center of any finite totally 2-closed group is cyclic and a finite nilpotent group is totally 2-closed if and only if it is cyclic or a direct product of a generalized quaternion group with a cyclic group of odd order.
Distilling entanglement with noisy operations
Authors: Chang Jinho , Bae Joonwoo , Kwon Younghun
Published: March 2017

Entanglement distillation is a fundamental task in quantum information processing. It not only extracts entanglement out of corrupted systems but also leads to protecting systems of interest against intervention with environment. In this work, we consider a realistic scenario of entanglement distillation where noisy quantum operations are applied. In particular, the two-way distillation protocol that tolerates the highest error rate is considered. We show that among all types of noise there are only four equivalence classes according to the distillability condition. Since the four classes are connected by local unitary transformations, our results can be used to improve entanglement distillability in practice when entanglement distillation is performed in a realistic setting.

Published: March 2017

The localized surface plasmon resonance (LSPR) properties of Au/Ag/graphene nanoshells are studied by discrete dipole approximation (DDA). The coupled resonance wavelengths show a remarkable dependence on the graphene thickness as well as refractive index of the surrounding medium. The resonance wavelengths of Au/Ag/graphene nanoshells red-shift as the thickness of the graphene layer is increased, when the radii of the Au core and Ag interlayer are 40[Formula: see text]nm and 45[Formula: see text]nm, respectively. Specifically, the longer wavelength red-shifts from 540[Formula: see text]nm to 740[Formula: see text]nm when the refractive index varies from 1.25 to 2.05.
A Global-Relationship Dissimilarity Measure for thek-Modes Clustering Algorithm
Authors: Zhou Hongfang , Zhang Yihui , Liu Yibin
Published: March 2017

Thek-modes clustering algorithm has been widely used to cluster categorical data. In this paper, we firstly analyzed thek-modes algorithm and its dissimilarity measure. Based on this, we then proposed a novel dissimilarity measure, which is named as GRD. GRD considers not only the relationships between the object and all cluster modes but also the differences of different attributes. Finally the experiments were made on four real data sets from UCI. And the corresponding results show that GRD achieves better performance than two existing dissimilarity measures used ink-modes and Cao’s algorithms.

Objective: Substance use treatment is often performed inside locked wards. We investigate the effects of adopting a policy of open-door treatment for a substance use treatment and dual diagnosis ward. Methods: This is a prospective open-label study investigating 3-month study periods before opening (P1), immediately after (P2), and 1 year after the first period (P3). Data on committed patients, coercion (seclusion, forced medication, absconding events with subsequent police search), violence, and substance use was collected daily. We applied generalised estimating equation models. Results: The mean daily number of patients with ongoing commitment changed from 2.64 (P1) to 2.12 (P2) to 0.96 (P3), corresponding to a reduction of relative risk (RR) for having an ongoing commitment by 20% in P2 (RR 0.80; 95% CI 0.66-0.98) and 67% in P3 (RR 0.33; 95% CI 0.25-0.42). The mean daily number of coercive events was 0.29, 0.13, and 0.05, corresponding to a risk for undergoing coercive measures reduced by 56% (RR 0.44; 95% CI 0.22-0.90) and 85% (RR 0.15; 95% CI 0.05-0.45). Substance use, violence or ward atmosphere did not differ significantly. Conclusions: Our results support findings from general psychiatric wards of reduced coercion after adopting a primarily open-door policy. However, coercive events were rare during all periods. The widespread practice of restricting the freedom of inpatients with substance use disorders by locking ward doors is highly questionable.

Aims: To evaluate cytological alterations, inflammation, and microbial charge of the oral mucosa epithelium in crack users in in terms of the amount and duration of use. Methods: Two hundred thirty four crack users (case group) and 120 non-users (control group) participated in this study. Clinically healthy epithelial cells were collected from the posterior mouth floor, using the conventional exfoliative cytology. Some of the aspects evaluated were as follows: Papanicolaou classification, nuclear area (NA), cytoplasmic area (CA), nuclear/cytoplasmic area ratio (NA/CA), inflammation, microbial charge, keratinization, enucleated superficial cells, and binucleation. Results: The average time of crack consumption was 9.8 years (±7.1) and the average quantity of use was 13.97 g/week (±18.5). The average NA values and NA/CA ratio were increased and CA values were decreased in the case group compared to those in the controls (p < 0.05). Papanicolaou class II, intense inflammation, and intense microbial charge were more prevalent in the case group than in the controls (p < 0.05). There was a significant association between high quantity of smoked crack rocks per week and increased CA values, absence of keratinization, and presence of enucleated superficial cells (p < 0.05). Conclusion: Crack use seemed to induce inflammatory alterations and early indicators of malignant transformation on the oral mucosa epithelium.

Published: March 2017

Congenital Bochdalek hernia is a defect of the diaphragm and very rare in adults. Only around 100 cases have been reported in the literature. Herein, we present a case with a recurrent ovarian cancer who underwent secondary cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. An oval defect with dimensions of 3 × 4 cm was seen in the left posterolateral site of the diaphragm during surgical exploration. In addition, a 6 × 3 cm iatrogenic right-sided diaphragmatic defect was found and repaired. In the early postoperative period, a bilateral thalamic infarction occurred.

Authors: Bent John P. , Fried Marvin P. , Smith Richard V. , Hsueh Wayne , Choi Karen
Published: March 2017

Although residency training offers numerous leadership opportunities, most residents are not exposed to scripted leadership instruction. To explore one program’s attitudes about leadership training, a group of otolaryngology faculty (n = 14) and residents (n = 17) was polled about their attitudes. In terms of self‐perception, more faculty (10 of 14, 71.4%) than residents (9 of 17, 52.9%; P =. 461) considered themselves good leaders. The majority of faculty and residents (27 of 31) thought that adults could be taught leadership ability. Given attitudes about leadership ability and the potential for improvement through instruction, consideration should be given to including such training in otolaryngology residency.

Authors: Tawfik Kareem O. , Ishman Stacey L. , Altaye Mekibib , Meinzen‐Derr Jareen , Choo Daniel I.
Published: March 2017

Objectives

(1) Describe longitudinal trends in annual prevalence of hospital admission for pediatric acute otitis media (AOM) and complications of AOM (CAOM) since introduction of pneumococcal vaccination in 2000 and (2) describe the longitudinal trend of prevalence of hospital admission for pneumococcal meningitis in children with AOM‐related diagnoses in the postvaccination era.

Study Design

Retrospective analysis of Kids’ Inpatient Database from 2000 to 2012.

Setting

Community, nonrehabilitation hospitals.

Subjects and Methods

To determine annual prevalence of admission for AOM/CAOM, nationally weighted frequencies of children aged <21 years with acute suppurative otitis media, acute mastoiditis, suppurative labyrinthitis, and/or acute petrositis were collected. The frequency of coexisting pneumococcal meningitis diagnoses among these patients was also collected. Trend analysis of prevalences of admission for AOM/CAOM and for pneumococcal meningitis occurring in the setting of AOM/CAOM from 2000 to 2012 was performed.

Results

Between 2000 and 2012, annual prevalence of admission for AOM/CAOM decreased from 3.956 to 2.618 per 100,000 persons (P <. 0001) (relative risk reduction 34%). Declines in admission prevalence were most pronounced in children <1 year of age (from 22.647 to 8.715 per 100,000 persons between 2000 and 2012, P <. 0001) and 1 to 2 years of age (from 13.652 to 5.554 per 100,000 persons between 2000 and 2012, P <. 0001). For all ages, the admission prevalence for pneumococcal meningitis and concomitant AOM/CAOM decreased (from 1.760 to 0.717 per 1,000,000 persons, P <. 0001) over the study period.

Conclusions

The prevalence of hospital admission for pediatric AOM/CAOM has declined since the advent of pneumococcal vaccination. Admission rates for pneumococcal meningitis with AOM/CAOM have similarly declined.

This review intends to summarize recent development on the potential nutrition implications of acute inflammation encountered during critical illness. Different aspects of the inflammatory response and their impact on nutrition management during critical illness will be discussed: the timing of the postinjury metabolic response, the integration of regulatory mechanisms involved in the metabolic response to stress, the oxidative stress, the metabolic and clinical consequences in terms of energy expenditure, use of energy, changes in body composition, and behavior.
Nurse-led parasite control
Authors: Wright Ian
Published: March 2017

This article explores the development of parasite-control plans and the role of veterinary nurses in their development. Through identification of risk and improved education of clients, the veterinary nurse can increase compliance and therefore the health of pets. This can be achieved throughout veterinary practices but dedicated nurse-run parasite-control clinics offer an opportunity for nurses to spend time with clients and assess their pet's parasite control needs. Parts of this article are based on an article to be published in April issue of The Veterinary Nurse Journal entitled ‘Parasite control clinics and the role of the veterinary nurse’, which will expand further on some of the themes explored here.
Let's talk about stress
Authors: Hargrave Claire
Published: March 2017

This article forms an introduction to stress in companion animal species — what it is, why does it occur and how it does it affect the pets in our care and their behavioural choices. A series of subsequent articles will examine, in more detail, the nature and alleviation of stress in specific companion animal species. Many companion animals live in environments for which they are ill-prepared, resulting in an inability to relax and frequent (if not chronic) exposure to stressors that maintain physiological and neurochemical arousal, with the accompanying predisposition to stress-related health problems. Despite the relative enormity of this welfare problem, recognition of individual animals suffering distress and the prevention of distress is rarely discussed with owners during routine surgery visits.

Published: March 2017

A espirometria é o método aceite para o diagnóstico da DPOC (Doença Pulmonar Obstrutiva Crónica), uma doença com elevados custos sociais. Para determinadas profissões, nomeadamente as que envolvem robustez física, o risco da DPOC pode ser avaliado através de uma espirometria. Neste trabalho, a partir de uma colecção de dados, foi avaliado o tipo de patologia: doença ventilatória obstrutiva e/ou doença ventilatória restritiva. Os  resultados mostram que o volume expiratório forçado no 4º segundo deve ser valorizado em substituição da capacidade vital forçada e um novo indicador de triagem foi introduzido a partir do tipo de escoamento. https://doi.org/10.14195/1647-7723_24_12

Grenzüberschreitungen (in) der Kunst
Authors: Acil Tufan
Published: March 2017

Das Wort »Grenzüberschreitung« ist in Kunstzeitschriften und Feuilletons allgegenwärtig. Überschreitet man eine Grenze, so die scheinbar unvermeidliche Konsequenz, verlässt man das umgrenzte Territorium. Jedoch scheint dies in der Ästhetik nicht der Fall zu sein. Viele Kunstpraktiken werden als »grenzüberschreitend« bezeichnet und trotzdem weiter als dem Gebiet »Kunst« zugehörig betrachtet. Wie also lässt die Reichweite der Kunst - im Gegensatz zu Ethik oder Politik - unterschiedliche Grenzüberschreitungen zu? Tufan Acil entwickelt anhand von ästhetischen Theorien von Kant, Adorno und Derrida ein Konzept der Grenze, das die konstitutive Rolle der Überschreitungen der Künste für eine Kunsttheorie plausibel zur Geltung bringt.

Published: March 2017

The FIR/submm window is one of the least-studied regions of the electromagnetic spectrum, yet this wavelength range is absolutely crucial for understanding the physical processes and properties of the ISM in galaxies. The advent of the Herschel Space Observatory has opened up the entire FIR/submm window for spectroscopic studies. We present the first FIR/submm spectroscopic results on both nearby and distant galaxies obtained in the frame of two Herschel key programs: the Very Nearby Galaxies Survey and the Herschel ATLAS.

Published: March 2017

The kinetics study, modeling, simulation and optimization of water gas shift reaction were performed in a catalytic fixed bed reactor. The renowned empirical power law rate model was used as rate equation and fitted to experimental data to estimate the kinetics parameters using gPROMS. A good fit between predicted and experimental CO conversion data was obtained. The validity of the kinetic model was then checked by simulation of plug flow reactor which shows a good agreement between experimental and predicted values of the reaction rate. Subsequently, considering axial dispersion, a homogeneous model was developed for simulation of the water-gas shift reactor. The simulation results were also validated by checking the pressure drop of the reactor as well as the mass concentration at equilibrium. Finally, a multi-objective optimization was conducted for water-gas shift reaction in order to maximize hydrogen formation and carbon monoxide conversion, whereas the reactor volume to be minimized. Implementation of optimal controls leads to increase in hydrogen formation at reactor outlet up to 25.55 %.
More than Words: Examining Actions of Power through Extra-verbal Domains in Theological Education
Authors: Cronshaw Darren , Waldron Barnett Elizabeth
Published: March 2017

Theological education, in line with mainstream academic culture, has delivered and assessed content primarily through the exchange of words. In turn, ecclesial practice, liturgy, mission, discipleship, and general teaching in the wider church has reflected this heavy verbal (rhetorical and literary) bias. This article reviews the cultural content and power dynamics of our common modes of delivery and assessment in theological education. Exploring the call to justice, inclusion and wholeness as markers of the way of Jesus and as fundamental rubrics for theological communities we will consider: a) Philosophical and pedagogical constructs that inform the intersection of mainstream academic discourse and mainstream theological education; b) Possibilities for explicitly engaging a diversity of age, gender, culture, agency, cognition and ability as normative anthropological samples; c) Resources already present, but somewhat latent, within Christian tradition for engaging non/extra-verbal theology; d) Examples of tasks in theology which educate beyond words.

Also, patients with non-colorectal liver metastases are increasingly offered surgery due to the low morbidity and excellent long-term results. The evolution of two-stage procedures helps to increase resectability. Also, laparoscopic and robotic liver surgery are constantly developed.
Multimodal constructs – multimodal constructions? The role of constructions in the working memory
Authors: Hoffmann Thomas
Published: March 2017

Language is a symbolic system, whose basic units are arbitrary and conventionalized pairings of form and meaning. In fact, in light of substantive empirical evidence, Construction Grammar approaches advocate the view that not only words but all levels of grammatical description – from morphemes, words, and idioms to abstract phrasal patterns as well as larger discourse patterns – comprise form-meaning pairings, which are collectively referred to as constructions. In this paper, I will discuss the status of multimodal usage-events (multimodal constructs) for the potential entrenchment of multimodal constructions and their implications for human cognition in general. As I will argue, constructionist approaches need to pay more attention to the role of the working memory in assembling and interpreting constructions. Drawing on verbal as well as gesture constructions, I will show that it is essential to distinguish entrenched constructions that are stored in the long-term memory from form-meaning pairings that are assembled in the working memory (online constructions). Once this distinction is made, the precise role of multimodal constructs and the nature of multimodal constructions can finally be disentangled.
Synthesis and evaluation of N,N-di-alkyl-2-methoxyacetamides for the separation of U(VI) and Pu(IV) from nitric acid medium
Authors: Kumaresan R. , Prathibha T. , Robert Selvan B. , Venkatesan K. A. , Antony M. P.
Published: March 2017

The homologs of N,N-di-alkyl-2-methoxyacetamides (DAMeOA) having three different alkyl chains varying from hexyl to decyl (C6, C8 and C10) were synthesized and characterized by NMR and IR spectral analyses. Extraction behavior of U(VI) and Pu(IV) from nitric acid medium in a solution of 0.5 M of DAMeOA in n-dodecane (n-DD) was studied and the results were compared with those obtained using N,N-di-hexyloctanamide (DHOA) in n-dodecane. The effect of various parameters on the distribution ratio of U(VI) and Pu(IV) in DAMeOA was studied. The extraction of nitric acid increased with decrease in chain length of alkyl group attached to amidic nitrogen atom of DAMeOA and the conditional nitric acid extraction constant was determined. The extraction of nitric acid in DAMeOA/n-DD resulted in the formation of third phase in organic phase and the third phase occurred early with DAMeOA having smaller alkyl chain length. In contrast to this, the distribution ratio (D) of U(VI) and Pu(IV) in DAMeOA/n-DD increased with increase in the concentration of nitric acid and with increase in the chain length of alkyl group attached to amidic nitrogen atom of DAMeOA. The stoichiometry of the metal – solvate was determined from the slope of extraction data. Quantitative recovery of uranium and plutonium from the loaded organic phase was achieved using dilute nitric acid.
Spannungsgeregelte Impedanzspektroskopie mit breitbandigen Anregungssignalen für Lithium-Ionen-Zellen in Kfz-Anwendungen
Authors: Haußmann Peter , Melbert Joachim
Published: March 2017

Die Impedanzspektroskopie für elektrochemische Systeme ist eine etablierte
Methode zur Charakterisierung der elektrochemischen Eigenschaften von
Lithium-Ionen-Zellen. Anhand der frequenzabhängigen Zellimpedanz ist eine
simultane Analyse unterschiedlicher elektrochemischer Prozesse im Zellinneren möglich. Lithium-Ionen-Zellen für Kfz-Anwendungen
weisen typischerweise einen geringen Innenwiderstand im mΩ-Bereich auf. Die Impedanzspektroskopie an derartigen Messobjekten erfordert daher ein angepasstes Verfahren, bei dem die Anregungssignalform und deren technische Realisierung optimal gewählt sind. In diesem Beitrag wird ein Synthesekonzept für breitbandige Anregungssignale vorgestellt. Der Ansatz basiert auf der inversen Fourier-Transformation und dient zur Erzeugung von Signalen mit geringer Auslenkung im Zeitbereich bei gleichzeitig hoher spektraler Anregungsleistung im betrachteten Frequenzbereich. Verfahren der Strom- und Spannungsanregung werden gegenübergestellt, deren jeweilige Vorteile sich in der Quasi-Spannungsanregung kombinieren lassen. Zur Realisierung der Quasi-Spannungsanregung mit beliebigen Spannungszeitverläufen wird eine geregelte Stromanregung eingesetzt. Mit Hilfe einer modellbasierten Simulation wird der Regler für eine Vielzahl unterschiedlicher Messobjekte mit signifikant abweichenden Impedanzeigenschaften dimensioniert und eine allgemeingültige Vorschrift für die Reglerdimensionierung für beliebige Zellen aufgestellt. Die Eigenschaften des neuen Verfahrens werden durch Messungen an Lithium-Ionen-Zellen belegt. So ermittelte Impedanzspektren zeigen gute Übereinstimmung mit etablierten Messverfahren und erreichen hohe Frequenzauflösung und Ergebnisgüte bei deutlich verkürzter Messdauer und geringerem Ladungsdurchsatz.

Abstract:

Advanced abdominal pregnancy is extremely rare. Symptoms are often nonspecific, and the diagnosis is frequently missed. Maternal mortality and morbidity are also very high especially if the condition is not diagnosed and managed properly. In abdominal pregnancy there is a high incidence of fetal malformations. We are presenting a case of a 38 year old primigravida with an undiagnosed advanced abdominal pregnancy carried beyond 36 weeks of gestation. We delivered a 2090 g baby from the abdomen. A relaparotomy was necessary on the third postoperative day because of abdominal bleeding. At the time of discharge both mother and baby were doing well. The publication also provides a literature overview, including definition, epidemiology, diagnosis and therapy. Orv. Hetil., 2017, 158(13), 508–511.
Embedding an allied health service in the Nelson hospital emergency department: A retrospective report of a six month pilot project
Authors: Holmes Clare , Hollebon Debbie , Scranney Alice , Exton Hilary
Published: March 2017

Embedding allied health into the emergency department (ED) was considered the best option by a 2011 Nelson Marlborough District Health Board (NMDHB) strategic planning group exploring innovative ways to bridge the gap between primary care and the ED and thus enhance the service. A six month pilot project implemented in 2012 aimed to provide a more timely multidisciplinary approach to patient care, facilitate safe discharge and linkages into the primary care sector, reduce multiple presentations and keep within ED designated time frames. Physiotherapy and social work practitioners worked as part of an inter-disciplinary team to comprehensively assess clients’ specific needs. The establishment of primary physiotherapy contact, where appropriate patients were identified directly from initial presentation, solely assessed and treated by the physiotherapist improved patient flow for lower triage presentations and made full use of staffing resources. Data collection over the first 22 weeks showed the allied health practitioners in ED had 749 new patient contacts, including 120 primary physiotherapy contacts. ED patients found the service extremely helpful. Survey responses from key stakeholders and ED staff highlighted the benefit of allied health interventions in improving safety of ED discharges, and the value of comprehensive client centred patient care. The Executive Leadership Team of the NMDHB unanimously endorsed the continuation of the allied health service in the emergency department from December 2012.
META-ANALYSIS OF THE RESEARCH OF IL-6 IN PERIPHERAL BLOOD OF PATIENTS WITH INFLUENZA A(H1N1)pdm09
Authors: Shipilov M. V. , Tutelian A. V.
Published: March 2017

Interleukin-6 (IL-6) is a potent proinflammatory cytokine, which level is increased in the peripheral blood in many infectious diseases, including the flu A(H1N1)pdm09, in some cases (when the excess of his development of immune cells), resulting not only to strengthen the immune system, but also to the development of a “cytokine storm” is characterized by multi-organ failure and often followed by death. To reduce errors, increase the statistical power and increase the reliability of the results according to different researchers, as well as on the results of their own research was conducted a meta-analysis (a quantitative systematic review) of IL-6 studies in peripheral blood of patients with influenza A(H1N1) pdm09. Question: to determine with a high level of confidence, whether IL-6, a marker of the severity and prognosis of the disease. Searches were carried out research work on this subject in a variety of electronic databases (Medline, EMBASE, the Cochrane Controlled Trials Register, and others), reviews, theses, magazines, conference proceedings, and others. In the process of carrying out a meta-analysis of 5 scientific papers were selected that meet the criteria for inclusion/noninclusion in the study (characteristic of scientific papers, diagnostic criteria, age of patients, comparable groups of patients, the presence of self-control, research methodology, statistical criterion and the total number of independent stu dies). Selected studies have shown sufficient uniformity (homogeneity) comparison groups. The results of the meta-analysis are presented in tables, charts and blobogramme, meta-analysis of 5 scientific papers showed that in moderate and severe influenza A(H1N1)pdm09 noted a significant increase in the concentration of IL-6 in peripheral blood of patients compared with the control a group of individuals (healthy). Severe influenza A(H1N1)pdm09 with a high probability of death is characterized by an even greater increase in IL-6 levels (in comparison with the moderate flow) — 11 pg/ml or more. Thus, the results of a meta-analysis of IL-6 with a high degree of probability is defined as a biomarker of disease severity and prognosis of development. At the same time, a result of meta-analysis of observed quite significant changes of the absolute values of the concentration of IL-6 in peripheral blood, which can be explained by using various test patterns and laboratory equipment, so that necessary to accumulate research experience level IL-6 on one and the same test systems and laboratory equipment.
ACESSO TRANSCONJUNTIVAL NA ABORDAGAGEM DE FRATURA DO ASSOALHO ORBITAL: RELATO DE CASO
Authors: Dantas Bruna Pedral Sampaio de Souza , Del’Arco Alana , Freitas Daniel , Azevedo Roberto Almeida de , Tourinho Laise
Published: March 2017

Objetivo: As fraturas na face necessitam de abordagens com resultados estéticos previsíveis, buscando acessos que minimizem cicatrizes e com baixos índices de complicações. Dentre os acessos extraorais para abordagem da margem infraorbital são descritos acessos cutâneos (subciliar, subtarsal e infraorbitário) e o transconjuntival com algumas variantes. Os acessos transconjuntivais possibilitam a exposição do assoalho da órbita, rebordo infraorbitário e parede medial da órbita para colocação de enxertos, osteotomias e ostessínteses, deixando cicatriz imperceptível na conjuntiva. O complexo zigomático está anatomicamente situado no terço médio da face e devido a sua projeção anteriorizada é bastante acometido por traumatismos, sendo a estrutura óssea facial, depois dos ossos próprios do nariz e da mandíbula, mais sujeita a fraturas.

Introduction: Beaches are a place for interaction and leisure, as well as a scenery for the provision of services, including the street food trade. In this segment, different workers with different type of foods are included, especially the popsicles.  Methods: This study aimed to characterize microbiologically the popsicles commercialized on the beaches of Salvador, Bahia State. A cross-sectional study was carried out on 13 beaches, with the application of semi- structured questionnaires to 33 vendors  to  characterize  microbiologically  the  popsicles sold on the beaches of Salvador, Bahia State, and the collecting of 198 samples, which were submitted to analysis: counting of Psychrotrophic microorganisms and coagulase-positive staphylococci, estimation of the Most Likely Number of total and thermolerant Coliforms/Escherichia coli and Salmonella spp research. Results: The results showed that in the microbiological profile, most of the samples were in compliance with the standards. However, 34.3% (68) of non-compliance were recorded, including contamination by the various microorganisms studied, except for Salmonella spp., which was not identified. Conclusion: The study identified risks to the costumer's health, given the contamination in the products, for both groups of sellers.
Complement receptor 2 (CR2/CD21)
Authors: Dash Rozaleen , Das Nibhriti
Published: March 2017

Human complement receptor type 2 (CR2/CD21) is a surface-associated glycoprotein which binds to a variety of endogenous ligands, including the complement component C3 fragments iC3b, C3dg and C3d, the low-affinity IgE receptor CD23, and the type I cytokine, interferon-alpha. This receptor serves as an important interface between the complement system and adaptive immunity. It is expressed on B-lymphocytes, follicular dendritic cells, some epithelial cells, peripheral blood T cells. CR2 also play an important role in enhancing humoral immunity to T-dependent and T-independent foreign antigens and in regulating T-cell immunity to self and non-self-antigens. It is an important receptor that amplifies B lymphocyte activation by bridging the innate and adaptive immune systems. CR2 ligands include complement C3d and Epstein-Barr virus glycoprotein 350/220. Regions of EBV have structural similarity to C3dg, which allows it to bind CR2, and thereby gain access to cell’s interior. It also acts as receptor for other components or activators of innate immunity such as IFN-α, an anti-viral cytokine and DNA-DNA containing complexes such as chromatin. The binding of CR2 to IFN-α is speculated to cause B cell activation but their roles are still not clear. Variations or deletions of the CR2 gene in humans, or the Cr2 gene in mice associate with a variety of autoimmune and inflammatory conditions.
School safety and emergency preparedness in Saudi Arabia: a call for effective action
Authors: Alsubaie Ali S. R.
Published: March 2017

Accidents and injuries are a growing global public health problem. Both accidents and injuries can happen anytime and anywhere. Children and school personnel might experience medical emergency situations because of injuries, complications of chronic health conditions, or unexpected major accidents that occur in schools. A safe learning environment is essential for students, and without it they are unable to focus on learning the skills needed for a successful education and future development. There are about 6 million children younger than 18 years living in the kingdom of Saudi Arabia. Regrettably, many accidental tragedies occurred during the few last years in schools in Saudi Arabia which caused many forms of injuries and death among children and school teachers. Unfortunately, most schools lack a health care professional to respond to school medical emergencies. It is essential to believe that there is a fundamental link between emergency preparedness and disaster response. Therefore, schools that are prepared for an emergency are more likely to be prepared for complex events such as major fire, injury related accidents and natural disaster. The quality of schools about safety management and emergency preparedness is far worrying in Saudi Arabia. Thus, there is a need in creating a ‘‘culture of safety’’ and realize that injuries prevention and safety promotion are everybody’s business. The time has come to develop effective injury prevention strategies and promote safety that can help reduce the impact of injuries on the health of the Saudi population, economy and health care system. The issue of school safety must be a major concern at all levels of government. Efforts should be made to increase the education of school personnel in the assessment and management of safety and life-threatening emergencies, particularly head injury, cardiac arrest, suffocation and fire events.

Authors: Ravindran Aju , M. Sagesh
Published: March 2017

Background: Otomycosis can be a difficult problem to treat in a patient who already has a perforation of the tympanic membrane. This study highlights the effectiveness of oral Itraconazole in treating such cases.Methods: Thirty-four patients with otomycosis and a perforated tympanic membrane were included in the study and were treated with oral itraconazole and antibiotic ear drops. They were followed up for six weeks to look for treatment response and any recurrence.Results: Of the 34 patients in the study, 25 patients were fully cured with one week of oral Itraconazole therapy. Six out of the remaining 9 patients were cured of the disease with two weeks’ therapy. Three patients needed prolonged treatment and one patient had a recurrence at six weeks.Conclusions: Oral itraconazole therapy is an effective alternative to the traditional methods of treatment for otomycosis with tympanic membrane perforation.

Background: Respiratory distress is one of the commonest presentations necessitating hospital admission in newborn unit. Regardless of the cause, if not recognized and managed quickly, respiratory distress can escalate to apnoea, respiratory failure, cardiopulmonary arrest and death.Methods: A cross-sectional and descriptive study of newborns with respiratory distress admitted into the SCBU of LAUTECH Teaching Hospital, Osogbo, Nigeria. Respiratory distress was diagnosed by grunting, inspiratory stridor, nasal flaring and tachypnea (more than 60 breaths per minute), retractions in the intercostal, subcostal, or supracostal spaces and cyanosis. At admission, every neonate had a complete physical examination.Results: Of 625 babies admitted, 384 (61.4%) were males while 241 (38.6%) were females and 164 (26.2%) had respiratory distress. Respiratory distress was commoner among the preterms than term newborns. c2 = 44.7, p = 0.001. Leading causes of respiratory distress among the preterms were hyaline membrane disease, septicaemia, while among the term babies were perinatal asphyxia, transient tachypnoea of newborn and meconium aspiration. Sixty (36.6%) of the 164 babies with respiratory distress died. While 40.2% of the preterms died mainly from causes like hyaline membrane disease and septicaemia, 31.3% of term babies died from causes like perinatal asphyxia and meconium aspiration. Mortality from hyaline membrane disease was 46.9%, while perinatal asphyxia and meconium aspiration accounted for 38.9% and 40.0% respectively.Conclusions: Respiratory distress is therefore, a very common neonatal problem and it causes death of more than third of those affected. Emphasis should be geared towards reduction of preterm delivery, control of asphyxia and neonatal sepsis in order to reduce neonatal mortality in our environment.

Authors: Dhage Amod S. , Wilkinson Anne R.
Published: March 2017

Background: Communication between physicians and patients is a fundamental aspect of cancer care. Bad news could be defined as "any information, which adversely affects an individual's view of his or her future”. The aim of the research study was to explore the patient’s perspective on receiving cancer news and their expectations regarding the same.Methods: A cross-sectional study was performed in our tertiary care teaching hospital. 50 consenting cancer patients from 18 to 60 years of age were interviewed on the basis of a structured, validated questionnaire.Results: On analysis of the 50 patients ‘answers, it was found that 37 were females and 13 were males, the average age being 50.07 years. The common diagnosis in females was breast cancer (20 patients) and in males it was lung cancer (5 patients). All the patients wanted relatives present with them when the bad news was broken to them.  In 66.6% patients, the news was broken by a junior resident, 15% of the doctors didn't greet the patients, 10% of the patients were told the news suddenly, while 99% of the doctors didn’t explain any positive aspects of the disease related to the treatment outcome.Conclusions: This study provides an insight into the expectations of patients from their physicians with regard to the process of breaking bad news.

Authors: Rohilla Jyoti , Rohilla Aarti , Singh Kamal , Rathee Suresh Kanta
Published: March 2017

Background: Biceps brachii derives its name from its two proximally attached parts or ‘heads’ that is known as long head and short head. Two tendons form elongated bellies that though closely applied get fused within 7cm or so above the elbow joint. These variations should be kept in mind during surgical and diagnostic procedures done by clinicians.Methods: A total of 18 cadavers were dissected for two successive years during undergraduate and were observed for different patterns of fusion of two heads of biceps brachii.Results: The present study showed that frequency of fusion of heads of biceps brachii in its upper one-third part was observed less commonly while it was frequently observed in its middle one-third part.Conclusions: Variation in union of heads might be significant in causing compression of neurovascular structures because of their close relationship to the brachial artery and median nerve.

Published: March 2017

Background: Considerable number of cases of firecracker injuries is reported during the festive season of Diwali in India. The purpose of this study is to identify the clinico-epidemiological patterns of ocular injuries caused by firecrackers during this period.Methods: This was a prospective case series of patients attending eye OPD with ocular trauma sustained by Firecrackers during the festive season of Diwali, 2016 in a Tertiary Care Centre in Surat. Demographic data of all the patients and type of firecracker causing injury were noted. Ocular examination of all patients was performed at the time of presentation and on follow-up. Treatment received by the patients was noted.Results: Out of total 20 patients, 85% were male (17 out of 20). Mean age of the patients was 12.15 years and majority of patients (45%) were of 6 to 10 years’ age group. Most patients (85%) sustained injury by Single shot crackers like Bijili crackers and Timing bombs. The injuries reported ranged from Eyelid burns, conjunctival or corneal burns to partial thickness corneal tear and macular scar formation with interventions ranging from ocular wash with saline to repair of partial thickness corneal tear. Many of the injuries were caused because of negligence. Corneal epithelial defect was the most frequent injury (affecting 96% of the total no. of eyes affected) followed by Eyelid burns (affecting 56% of the total no. of eyes affected). Cases having visual impairment or blindness had corneal and/or retinal involvement.Conclusions: Ocular trauma resulting from firecrackers can lead to significant ocular morbidity and permanent blindness and is a preventable cause. All steps must be taken through public awareness and legislation to ensure that firecrackers are used in a safe manner during Diwali celebrations. The medical professionals should be adequately trained to give primary emergency care which has a key role in the visual outcome.
