Aspiração de corpo estranho na criança: um perigo escondido

Introdução: A aspiração de corpo estranho (ACE) é uma emergência pediátrica e uma causa importante de morte acidental na criança. A maioria dos casos ocorre com objetos orgânicos e inorgânicos de pequenas dimensões, sobretudo em idade pré-escolar. A ACE cursa com amplo espectro de manifestações e o seu diagnóstico representa muitas vezes um desafio. Caso clínico: Descrevemos o caso clínico de uma criança de dois anos que recorreu ao Serviço de Urgência por tosse, disfonia e disfagia. Ao exame objetivo apresentava acessos de tosse estridulosa, tiragem supra-esternal ligeira e auscultação pulmonar com sibilos inspiratórios/expiratórios e roncos dispersos bilateralmente. A telerradiografia do tórax evidenciava um reforço hilar bilateral, mais notável à direita. A avaliação por Otorrinolaringologia, incluindo a nasolaringofibroscopia, não de- mostrou alterações. A broncoscopia revelou a presença de corpo estranho vegetal condicionando obstrução superior a 50% do lúmen do brônquio principal direito. Conclusão: Pretendemos com este caso salientar a necessidade de manter alto índice de suspeição perante a possibilidade de ACE, pois o atraso no seu reconhecimento condiciona o seu tratamento e o eventual aparecimento de sequelas irreversíveis.

Towards sustainable transport: A comparison of demographic and behavioural characteristics of Finnish and international car sharing users

Strong evidence suggests that the climate is changing and that these changes are largely caused by human activities. A consensus exists among researchers that human activity is causing global warming and that actions to mitigate global warming need to be taken swiftly. The transportation sector, which relies heavily on fossil fuel burning and primarily oil, is one of the big contributors to air pollution problems at local, regional and global levels. It is the fastest growing source of greenhouse gas emissions and is estimated to be responsible for nearly a quarter of global energyrelated carbon dioxide emissions. Car sharing is a mobility solution encouraging its users to decrease private car usage in favour of communal transit and environmental goals. The idea of car sharing originates from the aspiration to decrease personal car ownership and to reduce vehicle distance travelled. This thesis seeks to complement the understanding of Finnish car sharing users and their usage through better categorization. Through better categorization and segmentation of Finnish car sharing users the thesis seeks to provide information for improved marketing insight. Research is done on the demographic and behavioural characteristics of Finnish car sharing users and they are compared with international findings about the characteristics of International car sharing users. The main research problem is Are Finnish car sharing users similar to international ones? A theoretical research framework on the determinants of individual car sharing usage is built based on international research about demographic and behaviouristic characteristics. After this a quantitative survey is performed to the customers of a Finnish car sharing organization. The data analysed in the thesis consist out of 532 answers received from the car sharing organizations customers. The data is analysed with descriptive and other exploratory methods, which create an understanding of Finnish car sharing users. At the end of the analysis the demographic and behavioural characteristics of Finnish car sharing users are compared with international ones. The research findings of the thesis indicate that the demographic and behavioural characteristics of Finnish car sharing usage largely follow those of their international counterparts. Thanks to the thesis results the car sharing organization is able to better target their customers through improved marketing insight.

Flexible bronchoscopy contribution in the approach of diagnosis and treatment of children’s respiratory diseases: the experience of a unique pediatric unit in Tunisia.

Objective: Our study aimed at assessing the role of flexible bronchoscopy (FB) in improving diagnosis and management of children’s respiratory conditions in the pediatric unit of FB, newly created and unique in Tunisia. Methods: Retrospective study including all the FB achieved in our pediatric unit from 2009 to 2014. Results: We performed 365 FB in 333 patients aged 46 months on average (1 month - 15 years), often under conscious anesthesia (81.6%). FB was performed for diagnostic purposes in 341 cases and for therapeutic purposes in 24 cases. Eight anatomical abnormalities were revealed in 22 patients. An intraluminal bronchial obstruction was found in 71 FB, mainly due to a foreign body (n=36). A vascular anomaly was responsible for nine cases out of 17 extraluminal obstructions. Airways malacia was observed in 60 FB. Bronchoalveolar lavage was performed in 196 cases. It was determinant in 43.9% of the cases. FB was of great diagnostic value in 74.8% of the cases. It influenced the management of the patients in 58% of the cases. The FB for therapeutic purposes was beneficial in all cases. Few complications occurred (5.5%). Conclusion: FB is a safe tool providing precious diagnostic and/or therapeutic help for the clinician. Keywords:

Between Nation and State: Albanian Associations from Ottoman Origins to a Communist Party, 1880 - 1945

This dissertation addresses the broader antecedents of the Communist Party of Albania (CPA) as one of a number of associations whose experience was central to Albanian political history. This long experience dates back to the informal national associations formed in the Ottoman Empire of the late nineteenth century. The dissertation examines the role of these associations which, pursuing language rights and political representation through imperial state reforms, set a pattern that struggled to connect nation and state, rather than asserting the territorial demands for a nation-state familiar across the region. Starting out in the Ottoman Empire, but then maturing in the Albanian diaspora in Romania, Bulgaria, Egypt and the United States, this dissertation shows politically significant processes of longer-term adaptation that created informal associations as institutional structures able to channel collective action. It then traces the reframing of these patterns through their destruction in the Balkan Wars and the First World War to the emergence of communist associations in the interwar period and beyond. This dissertation is a sustained study that traces long-term Ottoman imperial political legacies in the Albanian successor state. The story of the associations, based on hitherto unexamined archival documents, shows that the Albanians possessed a far greater capacity for political mobilization that previously acknowledged by historians. Moreover, the dissertation successfully challenges the conventional wisdom that portrays the Albanians as irreparably divided along sectarian and regional faultlines. It finds that Albanian national activism was civic in character rather than ethnic as elsewhere in the Balkans. The Albanians fought to remain within a multinational framework because this afforded them political security, social advancement and potential economic growth. In the late Ottoman period, this political objective was manifested in the acceptance of the supranational imperial order whereas during the Second World War, in the aspiration to become members of the Comintern internationalist movement. Another important find, is the newly-discovered evidence concerning the founding of the CPA and its wartime conduct as an organization created and led by the Albanians themselves, albeit with Yugoslav ideological assistance under the transnational umbrella of the Comintern.

Stroke in patients with diabetes mellitus: a study from North Western Nigeria.

Background: Stroke is one of the major causes of morbidity and mortality worldwide and apart from being exceedingly harmful in diabetics, stroke is a disabling disorder. The study was undertaken to describe the clinical characteristics, outcome pattern and predictors of mortality in a cohort of diabetic patients presenting with stroke in two tertiary health facilities in North Western Nigeria. Method: Out of all stroke patients seen from June 2007 to February 2011, persons with diabetes mellitus presenting with stroke in the emergency unit of the two tertiary hospitals in Kano were consecutively recruited for the study. Classification of stroke into hemorrhagic and infarctive subtypes was based on brain computerized tomography (CT), brain magnetic resonance imaging (MRI) and World Health Organization (WHO) criteria. Follow-up period was for thirty days. Result: Out of the five hundred and thirty six stroke patients seen during the study period, 85 (15.9%) patients, comprising 48 (56.5%) males, had diabetes. Thirty eight (44.7%) of the identified diabetics were previously undiagnosed. Sixty four (75.3%) had infarctive stroke. One-month case fatality rate was 30.6%. Factors associated with death included male sex, past history of TIA, abnormal respiratory pattern, hemorrhagic stroke, aspiration pneumonitis, and worsening GCS. Aspiration pneumonitis and worsening GCS were independent predictors of one month mortality of stroke in the patients. Conclusion: In DM patients studied, infarctive stroke was more common, case fatality was 30.6%. Male gender, past history of TIA, abnormal respiratory pattern, hemorrhagic stroke, aspiration pneumonitis, and worsening Glasgow Coma Score (GCS) were associated with mortality. Aspiration pneumonitis and worsening GCS were independent predictors of one month mortality of stroke in diabetic patients.

Microbiology of chronic suppurative otitis media at Queen Elizabeth Central Hospital, Blantyre, Malawi: A cross-sectional descriptive study

Background Chronic suppurative otitis media (CSOM) is still a significant health problem in developing countries. Therefore, it was pertinent to determine the local Malawian microbiology in order to guide adequate treatment, avoid complications, and provide records for future reference. Aim The study sought to determine the CSOM-causing microorganisms at Queen Elizabeth Central Hospital in Blantyre, Malawi, and establish their relationship signs and symptoms, and with the demographic pattern of the study. Methods This was a hospital-based cross-sectional descriptive study carried out at the ENT outpatient clinic and the Microbiology Department of Queen Elizabeth Central Hospital.The sample comprised 104 patients with unilateral or bilateral active CSOM, who met the inclusion criteria. All patients were evaluated through a detailed history and clinical examination. Pus samples from draining ears were collected by aspiration with a sterile pipette. The specimens were immediately sent for microbiological analysis. Data were analyzed using SPSS.version 20. Results The study found that Proteus mirabilis , Pseudomonas aeruginosa , and Staphylococcus aureus were the most prevalent aerobic bacteria, while Bacteroides spp. and Peptostreptococcus spp. were the commonest anaerobic bacteria causing CSOM. These CSOM-causing microorganisms were predominant among males aged 18 years and below. Some CSOMcausing microorganisms were—significantly more so than the others— characteristically associated with each of the following clinical features: quantity of pus drainage, mode of onset, otalgia, hearing loss, location of tympanic membrane perforation, and mucosal appearance.

The Influence of Place Attachment, Aspirations, and Rapidly Changing Environments on Resettlement Decisions

Resettlement associated with development projects results in a variety of negative impacts. This dissertation uses the resettlement context to frame the dynamic relationships formed between peoples and places experiencing development. Two case studies contribute: (a) the border zone of Mozambique’s Limpopo National Park where residents contend with changes to land access and use; and (b) Bairro Chipanga in Moatize, Mozambique where a resettled population struggles to form place attachment and transform the post-resettlement site into a “good” place. Through analysis of data collected at these sites between 2009 and 2015, this dissertation investigates how changing environments impact person-place relationships before and after resettlement occurs. Changing environments create conditions leading to disemplacement—feeling like one no longer belongs—that reduces the environment’s ability to foster place attachment. Research findings indicate that responses taken by individuals living in the changing environment depend heavily upon whether resettlement has already occurred. In a pre-resettlement context, residents adjust their daily lives to diminish the effects of a changing environment and re-create the conditions to which they initially formed an attachment. They accept impoverishing conditions, including a narrowing of the spaces in which they live their daily lives, because it is preferred to the anxiety that accompanies being forced to resettle. In a post-resettlement context, resettlement disrupts the formation of place attachment and resettled peoples become a placeless population. When the resettlement has not resulted in anticipated outcomes, the aspiration for social justice—seeking conditions residents had reason to expect—negatively influences residents’ perspectives about the place. The post-resettlement site becomes a bad place with a future unchanged from the present. At best, this results in a population in which more members are willing to move away from the post-resettlement site, and, at worse, complete disengagement of other members from trying to improve the community. Resettlement thus has the potential to launch a cycle of movement- displacement-movement that prevents an entire generation from establishing place attachment and realizing its benefits. At the very least, resettlement impedes the formation of place attachment to new places. Thus, this dissertation draws attention to the unseen and uncompensated losses of resettlement.

UNDERSTANDING CAREER ASPIRATIONS AMONG YOUNG WOMEN: IMPROVING INSTRUMENTATION

The purpose of this study was to improve an instrument used to assess career aspirations (the Career Aspiration Scale) so the revised measure can be used with confidence by counseling psychologists in research and practice. Three studies were conducted with a total of 583 undergraduate and graduate women. Results of these studies provided support for the reliability and validity of the Career Aspiration Scale-Revised when used with undergraduate and graduate women. Results from confirmatory factor analyses indicated that the three-factor solution had good model fit, thus supporting a revised measure with three subscales assessing achievement, leadership, and educational aspirations. Suggestions for future research and practice using the Career Aspiration Scale- Revised are provided.

Emerging pathogens in the central nervous system: a cerebral abscess by Streptococcus porcinus

Brain abscesses can cause an incapacitating neurological deicit in up to 50% of patients, thus the reduction of these sequelae becomes the main goal of its timely and speciic surgical and medical treatment. With technological advances in bacteriological identiication and diagnostic imaging, the clinical suspicion can be conirmed, and the speciic etiological agent can be identiied in a larger number of cases. New pathogens have emerged through this process, such as Streptococcus porcinus, in which the ability to affect the central nervous system has not been documented. A clinical case is presented of a brain abscess in an immunocompetent patient, and its favorable response to surgical drainage t hrough a skull burr h ole and nee dle aspiration with antibiotic therapy (ceftriaxone, metronidazole and vancomycin) is discussed.

Las relaciones entre el arte mural los espacios públicos y emblemáticos de la ciudad de Loja

La propuesta mural “Loja: Identidad Cultural” constituye una aspiración y requerimiento de la comunidad lojana, evidenciadas en el trabajo investigativo realizado en el Barrio Zamora de la ciudad de Loja, sector de la intersección de las calles José María Egas y Matilde Hidalgo de Procel, sobre el tema: “Las relaciones entre el arte mural, los espacios públicos y emblemáticos de la ciudad de Loja”. En el trabajo se pretende acercarse a la noción de espacio público con un recorrido por la historia que ayuda a dilucidar la diferencia entre lo público y lo privado. Así mismo, se advierte en las comunidades que las relaciones y acciones sociales, entre ellas el arte, constituyen elementos generadores de espacios propicios que fomentan el diálogo, la convivencia y la identidad. En uno de los capítulos se hace referencia al Muralismo como uno de los principales movimientos y corrientes de intervención del espacio público, sus orígenes, desarrollo y cómo se convirtió en una herramienta de poder político y de gestión en algunos países del mundo. También se realizó un breve estudio de los muralistas latinoamericanos, nacionales y locales, mediante un análisis comparativo y de registro de obras muralísticas que se encuentran en lugares públicos e importantes de la ciudad de Loja. La obra mural que fuera presentada y entregada a la comunidad lojana, en el acto público realizado el 18 de febrero del 2016 con la asistencia de representantes de las entidades seccionales, delegados de instituciones culturales, artistas plásticos, docentes y estudiantes de varios colegios de la ciudad; proyectó en su contenido el proceso histórico, aspectos culturales, personajes y elementos que buscan configurar la conciencia y la identidad lojana. La técnica que se utilizó en los 250 m2 es el acrílico y esmalte sobre ladrillo, mampostería y latón.

Évaluation de la biomasse fongique dans les systèmes de ventilation

Le nettoyage des systèmes de Chauffage, Ventilation et Climatisation de l’Air est important pour assurer une bonne qualité d’air intérieur. Le déclenchement de leur nettoyage est basé sur une inspection visuelle qui ne tient pas compte du contenu en moisissures, lesquelles ont des effets sur le système respiratoire. Cette recherche vise à proposer une méthode d’évaluation du contenu en moisissures afin d’aider les gestionnaires d’immeuble. Cinq générations de poussières ont été effectuées pour simuler un conduit de ventilation. Une cassette modifiée 37 mm et un filtre CPV pré-pesés ont utilisés pour collecter les poussières déposées avec une pompe calibrée à 15L/min. Les pourcentages de collecte des cassettes et des filtres ont été calculés pour 54 échantillons. Dix générations supplémentaires de poussières ont été effectuées concomitamment avec la génération de spores. Soixante échantillons ont été analysés selon quatre méthodes : culture, comptage direct des spores par microscopie (CDSM), dosage de β-N-acétylhexosaminidase (NAHA), 18S-q-PCR. La limite de détection (LD), la réplicabilité, la répétabilité, le nombre de spores et le coefficient de corrélation (r) ont été déterminés. Les récupérations de poussières étaient supérieures à 84%. Selon la méthode analytique, les concentrations médianes de spores/100 cm² allaient de 10 000 à 815 000. Les LD variaient dépendamment de la méthode de 120 à 218 000 spores/100 cm² et r de -0,08 à 0,83. La réplicabilité et la répétabilité étaient de 1% et 1% pour PCR; 5% et 10% pour CDSM; 6% et 15% pour NAHA; 12% et 11% pour culture. La méthode de collecte a démontré une excellente efficacité de récupération. La PCR est la méthode analytique recommandée pour l’évaluation fongique des systèmes de ventilation. Une validation terrain est en cours.
