Coastal Zone Ecosystem Services: From science to values and decision making; a case study

This research is concerned with the following environmental research questions: socio-ecological system complexity, especially when valuing ecosystem services; ecosystems stock and services flow sustainability and valuation; the incorporation of scale issues when valuing ecosystem services; and the integration of knowledge from diverse disciplines for governance and decision making. In this case study, we focused on ecosystem services that can be jointly supplied but independently valued in economic terms: healthy climate (via carbon sequestration and storage), food (via fisheries production in nursery grounds), and nature recreation (nature watching and enjoyment). We also explored the issue of ecosystem stock and services flow, and we provide recommendations on how to value stock and flows of ecosystem services via accounting and economic values respectively. We considered broadly comparable estuarine systems located on the English North Sea coast: the Blackwater estuary and the Humber estuary. In the past, these two estuaries have undergone major land-claim. Managed realignment is a policy through which previously claimed intertidal habitats are recreated allowing the enhancement of the ecosystem services provided by saltmarshes. In this context, we investigated ecosystem service values, through biophysical estimates and welfare value estimates. Using an optimistic (extended conservation of coastal ecosystems) and a pessimistic (loss of coastal ecosystems because of, for example, European policy reversal) scenario, we find that context dependency, and hence value transfer possibilities, vary among ecosystem services and benefits. As a result, careful consideration in the use and application of value transfer, both in biophysical estimates and welfare value estimates, is advocated to supply reliable information for policy making.

Autoimmune conditions and hairy cell leukemia: an exploratory case-control study

Background: Case reports suggest that hairy cell leukemia (HCL) may be associated with autoimmune conditions, however no systematic investigations in this area have been undertaken.

A Case Report on Parvovirus B19 Associated Myositis

Introduction: Whilst there are reports of viral myopathies affecting children and the immunocompromised, infective myositis is a relatively rare inflammatory myopathy in adults. The clinical spectrum can range from benign myalgias to more serious complications in certain risk groups. Case Presentation: We present two cases of myositis as a result of parvovirus B19 infection. <br/>Conclusion: Viral myositis and parvovirus B19 associated myositis should be considered in adults presenting with significant myalgia.

Does this case hold the answer to one of the worse types of pain in medicine--that of loin pain haematuria syndrome (LPHS)

A patient with loin pain haematuria syndrome suffering chronic throbbing pulsing pain overlaid with prolonged periods of incapacitating colic and overnight vomiting was presented 10 months following diagnosis. Ultrasound was normal. No renal or ureteral stones, or filling defects were seen on CT. At cytoscopy, bladder and urethra were normal, and bloody urine effluxed from the left ureteric orifice. The ureters were normal at diagnosis, and developed new abutting non‐penetrating calcifications by 8 months. Pain episodes of complete incapacitating intensity of 2–4 h duration were reduced to 10 min with 5 mg crushed tadalafil administered at onset. If tadalafil was delayed to after onset, the original course of agony resulted. Daily tadalafil reduced loin pain intensity, but not the exacerbations. Tadalafil efficacy may indicate that the pain exacerbations are due to spasm of ureter smooth muscle. 5 mg tadalafil taken at onset alleviated severe loin pain exacerbations in this case of loin pain haematuria syndrome.

Prestadores de cuidados familiares a doentes com VIH/SIDA: perfil psico-emocional e social

RESUMO: Com o presente estudo pretendemos identificar a sobrecarga resultante do envolvimento familiar com os doentes portadores de VIH/SIDA. Numa breve introdução teórica, procedemos à revisão dos conceitos sobrecarga familiar e dos sentimentos/emoções vivenciados pelos prestadores de cuidados. Metodologia: Estudo do tipo descritivo e exploratório, com uma amostra de 51 indivíduos, cuja finalidade consiste na caracterização dos prestadores de cuidados familiares a doentes com VIH/SIDA. Objectivos: Identificar quem o doente com VIH/SIDA, considera ser a pessoa significativa nos cuidados informais. Caracterizar, do ponto de vista sócio-demográfico, os doentes e os prestadores de cuidados familiares. Identificar sentimentos e emoções de vivências, que justifiquem o sofrimento emocional e as repercussões na sobrecarga familiar nos prestadores de cuidados informais. Instrumentos: Na avaliação da sobrecarga familiar, utilizámos o Questionário de Problemas Familiares”- FPQ (Family Problemas Questionnaire). Para identificação dos Acontecimentos de Vida, adoptámos a escala de Holmes e Rahe (Life Events); Para identificação do estrato social escolhemos escala de Graffar. Finalmente, para a caracterização sócio-demografica concebemos dois questionários: um dirigido aos doentes e o outro aos prestadores de cuidados informais. Conclusões: A sobrecarga da doença VIH/SIDA, nos prestadores de cuidados familiares, não é uniforme nas diferentes dimensões. A dimensão sobrecarga subjectiva é superior à objectiva. O suporte social revela-se fraco, relacionado com as perdas familiares, devidas a morte, pelas relações familiares disfuncionais, entre os membros da família, pela falta de apoio e informação dos técnicos de saúde. O sexo feminino é predominante nos cuidadores. As mães e esposas são o grau de parentesco dominante. Os solteiros são o grupo mais afectado pelo VIH/SIDA. Os cuidadores apresentam idade superior à dos doentes. O estrato social preponderante é o médio baixo e o baixo. Os familiares, apesar da atitude negativa dos doentes perante os cuidadores, mantêm-se envolvidos. Segundo a avaliação multiaxial proposta pelo DM-IV, constatámos, ao nível do eixo I, sintomatologia clínica do tipo das perturbações depressivas e perturbações da ansiedade. No eixo IV, os cuidadores evidenciam problemas psicossociais e ambientais, nomeadamente nas categorias problemas com o grupo de apoio primário, problemas relacionados como grupo social, problemas educacionais, problemas de alojamento, problemas económicos. Os problemas relacionados com o grupo de apoio primário, são os que mais parecem contribuir para os problemas psicossociais e ambientais.---------------------------------------ABSTRACT: This study wants to describe several problems as a result of the family’s relationship with HIV/AIDS patients, like overload. In a brief theoric introduction, we made a small revision about the concepts of family’s overload, and feelings or emotions that have been lived by the people who provide cares to the patients with this chronic disease. Methodology: This is a describing and exploratory study, with a sample with 51 individuals, with the aim to characterize the people inside the family who give care HIV/AIDS patients. Aim: To identify who are the most important people in informal cares from the patient perspective. To characterize, in a social-demographic point of view, patients and the people who take care of them. To identify feelings and emotions that could explain an emotional suffer, and some causes in the family burden. Means: to evaluate the family’s overload we used the Family Problems Questionnaire (FPQ). To identify life events we adopted the Holmes and Rahe scale. To identify the social stratum we used the Graffer scale. Finally to do a socio-economic characterization we did two kinds of questionnaire, the first one was directed for the patients, and the second one was chosen for the people who give care. Conclusions: The HIV/AIDS disease burden on the people who takes familiar cares isn’t uniform on several areas that we studied. The subjective overload it is superior to the objective. The social support is weak and poor, and related with family losses by dead, dysfunctional family relationships, and the lack of support and information by the medical staff. Mothers and wives are the dominant relative degree. And the singles are the major group with HIV/AIDS disease. The people who take care are usually older than the sick. The major social status is low or medium-low. The relatives keep evolved though the negative attitude of the sick. According with the evaluation multiaxial proposed by the DM-IV, in axle 1 we note clinic sintomatologic belonging to the type depressive perturbations and perturbations of the anxiety. Regarding with axle IV the caretakers show up psycho-social and environmental problems, namely on the categories: problems with the primary support group and problems related as social group, educational problems, accommodation problems and.

Mycobacterium tuberculosis aortic graft infection with recurrent hemoptysis: a case report.

INTRODUCTION: Mycobacterium tuberculosis may cause a large variety of clinical presentations due to its ability to disseminate by contiguity or hematogenously. Tuberculosis may remain undiagnosed for years due to the chronic course of the disease, with potentially life-threatening long-term complications. CASE PRESENTATION: In this case report, we describe a tuberculous aortic graft infection in a 72-year-old man documented by polymerase chain reaction and cultures. The patient presented with three episodes of hemoptysis following a remote history of miliary tuberculosis. The infection was treated by graft replacement and prolonged antimycobacterial therapy. CONCLUSION: Tuberculous infection of a vascular graft is an uncommon complication, but should be considered in patients with an intravascular device and a history of previous tuberculosis, especially when hematogenous spread may have occurred a few months after surgery, or when an active mycobacterial infection is present in close proximity to the graft.

L’asphyxie en médecine légale : une étude rétrospective de six ans sur les suffocations non-chimiques au Québec

La suffocation est une forme d’asphyxie dans laquelle l’oxygène ne peut atteindre le sang. Il existe divers types de suffocation dont la suffocation par confinement/ environnementale, les étouffements externe et interne, et les asphyxies traumatique/ positionnelle. La littérature scientifique sur la suffocation est relativement pauvre, étant principalement constituée de revues de cas et de quelques séries de cas limités à un contexte particulier de suffocation. Dans le contexte actuel d’une médecine basée sur les preuves, les ouvrages de médecine légale n’ont guère d’études pour appuyer leurs enseignements, tirés essentiellement de l’expérience personnelle de générations de médecins légistes. Le présent projet vise à palier ce manque de données sur la suffocation, un type de décès pourtant important en pratique médico-légale. Il s’agit d’une étude rétrospective de six ans portant sur tous les cas de suffocation non-chimique ayant été autopsiés au Laboratoire de sciences judiciaires et de médecine légale. À notre connaissance, cette étude est la première à établir le portrait systématique des morts par suffocation non-chimique en milieu médico-légal. Elle permet, entre autres, de confirmer les modes de décès usuels par catégorie de suffocation, le type de victime et les contextes courants. Généralement, les résultats concordent avec la littérature, appuyant ainsi le savoir commun des pathologistes sur la suffocation non-chimique. Toutefois, certaines dissimilitudes ont été notées quant aux modes de décès lors de l’étouffement externe. Par ailleurs, les questions reliées à la classification des asphyxies et aux définitions souvent contradictoires sont discutées. En un effort de normalisation, ce projet souligne les divergences retrouvées dans les classifications usuelles et tente d’en dégager les définitions courantes afin de proposer un modèle de classification unifié.

Paroxysmal upgaze deviation: case report

The paroxysmal upgaze deviation is a syndrome that described in infants for first time in 1988; there are just about 50 case reports worldwide ever since. Its etiology is unclear and though it prognosis is variable; most case reports indicate that during growth the episodes tend to decrease in frequency and duration until they disappear. It describes a 16-months old male child who since 11-months old presented many episodes of variable conjugate upward deviation of the eyes, compensatory neck flexion and down-beat saccades in attempted downgaze. These events are predominantly diurnal, and are exacerbated by stressful situations such as fasting or insomnia, however and improve with sleep. They have normal neurologic and ophthalmologic examination, and neuroimaging and EEG findings are not relevant.

Revisión sistemática de literatura de la neumonía lipoidea exógena (nle) por exposición laboral

Objetivo Realizar una revisión sistemática de la neumonía lipoidea exógena (NLE) con el propósito de compactar y sintetizar los conocimientos fragmentados, así como el de informar el estado actual de este tema como riesgo laboral. Metodología La neumonía lipoidea es una condición poco común que resulta de la presencia de lípidos en el interior del espacio alveolar, se desconoce su actual incidencia. La neumonía lipoidea exógena se produce por aspiración o inhalación de sustancias oleosas, es una patología rara en pacientes sin enfermedades de base que predispongan a la broncoaspiración y cuando se presenta en individuos sanos se debe sospechar un origen ocupacional. Se realizó una revisión de literatura según la metodología estandarizada, incluyendo en la búsqueda: reporte de casos, descripciones de la enfermedad y el uso de técnicas diagnósticas. Las bases de datos fueron OVID además de GOOGLE ACADÉMICO; buscadores específicos: MEDLINE, CHEST, PUB MED, REDALYC, SCIELO, Europe PubMed Central (Europe PMC) y ELSEVIER. La búsqueda estuvo además, orientada por una serie de preguntas orientadoras sobre la neumonía lipoidea exógena (NLE) como riesgo laboral. Los artículos que cumplieron con los criterios de inclusión, se clasificaron de acuerdo con tipo de estudio, la calidad del artículo y finalmente se evaluaron con base en una lista de chequeo ajustada para este fin. Resultados Se seleccionó un total de 71 estudios incluyendo reporte de casos, descripciones de la enfermedad y técnicas diagnósticas; publicaciones provenientes de 21 países. Un total de 63 casos, 31 en mujeres (49,20%) y 32 en hombres (50,8%) fueron reportados; el 7,93% de los casos fueron atribuidos a la exposición de agentes en el ambiente laboral: combustibles, parafina/pintura/ pulverizaciones oleosas y diésel, ambientes propios de trabajadores de almacenes de pinturas y conductores de vehículos. Los síntomas de la neumonía lipoidea exógena (NLE) descritos fueron muy variables, puede cursar asintomática o con presencia de fiebre, disnea y tos irritativa; dolor torácico, en algunos casos hemoptisis, cianosis y pérdida de peso; El examen físico generalmente es normal, aunque puede revelar sibilancias o roncus. En pruebas de función respiratoria tales como la espirometría, se presenta un patrón restrictivo, además puede hallarse un descenso en la capacidad de difusión para el monóxido de carbono. En el hemograma puede detectarse leucocitosis con predominio de neutrófilos y aumento de la velocidad de sedimentación globular, hallazgos que también pueden ser producidos por una infección concomitante. Conclusiones Se destaca el hallazgo en la literatura de los diferentes agentes causales presentes en el ambiente laboral que pueden incidir en la aparición de la enfermedad: combustibles, parafina/pintura/ pulverizaciones oleosas y diésel, ambientes propios de trabajadores de almacenes de pinturas y conductores de vehículos. Se presentó neumonía lipoidea exógena (NLE) de tipo agudo después de 30 minutos a 24 horas de exposición masiva a aceites y sustancias oleosas, luego de de ocho meses a 9,5 años de inhalación continua secundaria. Los métodos más para de la diagnóstico enfermedad incluyen el lavado broncoalveolar (BAL), la biopsia de pulmón y la con radiografía torácica. Finalmente, es posible que en pacientes con neumonía lipoidea exógena, puedan presentarse complicaciones asociadas tales como: sobreinfección, fibrosis, retracción de las lesiones, cáncer de pulmón, bronconeumonías recurrentes e hipercalcemia.

Representaciones sociales de la medicina complementaria y alternativa (MCA) para el cáncer en estudiantes universitarios de carreras de ciencias de la salud

Se realizó un estudio cualitativo exploratorio con estudiantes de carreras de Ciencias de la Salud con el objetivo de comprender las representaciones sociales que tienen acerca de la Medicina Complementaria y Alternativa (MCA) para el cáncer. Se desarrollaron grupos focales y la información obtenida fue analizada a través del Análisis Temático e interpretada con base en la Teoría de las Representaciones Sociales. Se encontraron diversas representaciones sociales asociadas con la definición, los objetivos, los tratamientos, la eficacia, las fuentes de información y el origen de la MCA. En conclusión se evidenció una alta tendencia a la aceptación y a la manifestación de una actitud positiva, aunque ambivalente frente a la MCA, además de un desconocimiento por la diferenciación conceptual entre este tipo de Medicina y la Medicina Popular. La cultura y las creencias sociales predominan en las representaciones sociales que tienen los estudiantes de la MCA para el cáncer, pese a su formación académica.

Asma ocupacional en peluquería: una revisión de la literatura

Este artículo pretende realizar una revisión de la literatura vigente acerca del asma ocupacional secundaria a la exposición de los factores de riesgo identificados en peluquería. Se realizó una búsqueda sistemática en las bases de datos PubMed y Cochrane de artículos de revistas indexadas con las palabras claves “Asthma occupational, hairdressers, hairdresser, work related asthma”. Aplicando los criterios de selección descritos, se revisaron 26 artículos en total donde se incluían reportes de casos, estudios de prevalencia, incidencia, corte transversa y revisiones, abarcando principalmente los temas de epidemiologia, fisiopatología, diagnóstico y prevención. Se agruparon según la metodología PRISMA para su respectiva comparación. Se concluyó que a pesar de la importancia de esta patología en el sector de peluquería, existen factores asociados como la informalidad del sector, la falta de estudios de investigación originales de cohorte o el desconocimiento de un protocolo claro de diagnóstico en este tipo de trabajadores, que limitan datos concluyentes acerca de la misma. Sin embargo, la mayoría de los autores concluye la relación entre la patología y la labor de peluquería, así falte esclarecer los mecanismos fisiopatológicos relacionados con los alérgenos identificados.

Uma cadela, fêmea, de raça Rottweiller de três anos de idade apresentou-se com sinais clínicos de diarreira crónica, perda de peso grave e vómito esporádico. A histopatologia revelou uma linfangiectasia intestinal com linfangite lipogranulomatosa. A linfangiectasia intestinal consiste numa dilatação patológica dos vasos linfáticos intestinais, sendo a causa mais frequente de enteropatia com perda de proteína no cão. Este trabalho consiste na apresentação do caso clínico e numa breve revisão da literatura.

Feline cutaneous lymphangioma : case report

This article describes a case report of a feline cutaneous lymphangioma. Lymphangiomas (synonym: lymphangiomatosis) and lymphangiosarcomas are rare tumors, usually associated with skin, some are believed to be congenital in young animals associated with vascular abnormalities. In gross pathology description they are poorly defined, cavernous-spongy, soft and they may be identified along fascial planes, because of this it may be difficult to remove, so tumors tend to recur. In histopathology description we can see interconnecting channels lined by endothelium usually without erythrocytes, but these tumors do not have unique features.

MOOCs: a systematic study of the published literature 2008-2012

Massive open online courses (MOOCs) are a recent addition to the range of online learning options. Since 2008, MOOCs have been run by a variety of public and elite universities, especially in North America. Many academics have taken interest in MOOCs recognising the potential to deliver education around the globe on an unprecedented scale; some of these academics are taking a research-oriented perspective and academic papers describing their research are starting to appear in the traditional media of peer reviewed publications. This paper presents a systematic review of the published MOOC literature (2008-2012): Forty-five peer reviewed papers are identified through journals, database searches, searching the Web, and chaining from known sources to form the base for this review. We believe this is the first effort to systematically review literature relating to MOOCs, a fairly recent but massively popular phenomenon with a global reach. The review categorises the literature into eight different areas of interest, introductory, concept, case studies, educational theory, technology, participant focussed, provider focussed, and other, while also providing quantitative analysis of publications according to publication type, year of publication, and contributors. Future research directions guided by gaps in the literature are explored.

Granulocytic sarcoma of the small intestine with CBF beta/MYH11 fusion gene: report of an aleukaemic case and review of the literature

Granulocytic sarcomas (GS) are rare extramedullary tumours composed of immature myeloid cells. Inversion of chromosome 16 [inv(16)] is a cytogenetic marker for M4Eo subtype of acute myeloid leukaemia (AML). The possibility of an association between the development of granulocytic sarcoma of the small intestine (GSSI) and the M4Eo subtype of AML was suggested in nine previous case reports.Here we report an aleukaemic case of GSSI with inv(16) and its molecular equivalent, the CBFbeta/MYH11 fusion gene, detected by reverse transcriptase-polymerase chain reaction (RT-PCR), that after treatment with conventional AML chemotherapy followed by autologous bone marrow transplantation, achieved complete haematological and molecular remission on bone marrow examination. After chemotherapy, a thickened ileum wall positive for CBFbeta/MYH11 on tumour mass samples was still observed on computed tomography (CT) studies, raising the question of residual GS representing a reservoir of malignant cells. This case demonstrates the critical need of multidisciplinary diagnosis and follow-up of this entity combining immunopathologic, cytogenetic and molecular studies, reinforcing the potentiality of risk-adapted therapy strategies, as it is increasingly claimed for patients with overt AML.
