ABSTRACT

Los hamartomas pulmonares son las lesiones benignas más frecuente del pulmón con un tamaño promedio de 1.0 a 2.0 cm. Se realiza el reporte de un caso de un hamartoma pulmonar gigante de 21 x 13 x 9,5 cm en un varón de 79 años quien presento un cuadro corto de síntomas respiratorios. En la tomografía de tórax se constató la presencia de una masa en el campo medio e inferior del hemitórax izquierdo. Se realizó la resección por toracotomía. El estudio histopatológico confirmo el diagnóstico de un hamartoma pulmonar gigante de tipo condroide.


Pulmonary hamartomas are the most common benign neoplasm in the lung, with an average size of 1.0 to 2.0 cms. We report a case of a giant pulmonary hamartoma in a 79 year old male who presented respiratory symptoms. Chest tomography revealed a heterogeneous mass that occupies the lower half of the left hemitoriax. The patient underwent thoracotomy and resection of the mass. Gross examination of the surgical specimen showed a well circumscribed mass measuring 21 x 13 x 9.5 cms. The histopathological study confirmed the diagnosis of a giant pulmonar hamartoma of the chondroid tape

ABSTRACT

El asma se ha considerado a menudo como una enfermedad cuyo inicio se produce en la infancia. Sin embargo, recientes estudios poblacionales han informado que el inicio del asma es común en las personas mayores. La carga sanitaria, personal y económica del asma puede ser más significativa en los ancianos que en sus homólogos más jóvenes, particularmente en lo que se refiere a la mortalidad, la hospitalización, los costos médicos o la calidad de vida relacionada con la salud. El asma en el Adulto Mayor (AAM) sigue siendo subdiagnosticada y subtratada. El objetivo principal de esta Revisión es identificar las necesidades no satisfechas en los campos de investigación y práctica para AAM, así como encontrar nuevas direcciones de investigación, proponer nuevas estrategias terapéuticas y mejorar los resultados para el creciente número de personas mayores con asma. El desafío de hoy es fomentar la investigación en AAM, utilizando el conocimiento existente para mejorar el diagnóstico, y los diagnósticos deferenciales, así como educar al paciente, desarrollar un enfoque terapéutico seguro y eficaz, controlar la enfermedad y, finalmente, proporcionar una mejor calidad de vida(AU)


Asthma has often been considered as a childhood disease. However, recent population studies reported that asthma is common in the elderly The burden of asthma may be more significant in the elderly than in their younger counterparts, particularly with regard to mortality, hospitalization, medical costs or health-related quality of life.Asthma in the Elderly (AIE) is still under-diagnosed and under-treated. The primary aim of this review is to identify unmet needs in the fields of research and practice for AIE. This will enable us to find new research directions, propose new therapeutic strategies, and ultimately improve outcomes for elderly people with asthma. The challenge today is to encourage new research in AIE, but to already use existing knowledge we have to make the diagnosis of AIE, educate the patient, develop a therapeutic approach to control the disease, and ultimately provide a better quality of life to our elderly patients(AU)

ABSTRACT

Abstract We believe that in tropics we need a community approach to evaluate road impacts on wildlife, and thus, suggest mitigation measures for groups of species instead a focal-species approach. Understanding which landscape characteristics indicate road-kill events may also provide models that can be applied in other regions. We intend to evaluate if habitat or matrix is more relevant to predict road-kill events for a group of species. Our hypothesis is: more permeable matrix is the most relevant factor to explain road-kill events. To test this hypothesis, we chose vertebrates as the studied assemblage and a highway crossing in an Atlantic Forest region in southeastern Brazil as the study site. Logistic regression models were designed using presence/absence of road-kill events as dependent variables and landscape characteristics as independent variables, which were selected by Akaikes Information Criterion. We considered a set of candidate models containing four types of simple regression models: Habitat effect model; Matrix types effect models; Highway effect model; and, Reference models (intercept and buffer distance). Almost three hundred road-kills and 70 species were recorded. River proximity and herbaceous vegetation cover, both matrix effect models, were associated to most road-killed vertebrate groups. Matrix was more relevant than habitat to predict road-kill of vertebrates. The association between river proximity and road-kill indicates that rivers may be a preferential route for most species. We discuss multi-species mitigation measures and implications to movement ecology and conservation strategies.


Resumo Nós acreditamos que nos trópicos, precisamos de uma abordagem de comunidade para avaliar os impactos das estradas sobre a vida silvestre, e então, sugerir medidas de mitigação para grupos de espécies ao invés da abordagem de espécie-foco. Compreender quais características da paisagem indicam eventos de atropelamento podem também fornecer modelos que podem ser aplicados em outras regiões. Nós pretendemos avaliar se habitat ou matriz é mais relevante para prever eventos de atropelamento para grupos de espécies. Nossa hipótese é: matriz mais permeável é o fator mais relevante para explicar os eventos de atropelamentos. Para testar essa hipótese, escolhemos vertebrados como a assembléia estudada e uma rodovia cruzando uma região de Mata Atlântica no sudeste do Brasil como área de estudo. Modelos de regressão logística foram criados usando presença/ausência de eventos de atropelamentos como variáveis dependentes e características da paisagem como variáveis independentes, os quais foram selecionados pelo Critério de Informação de Akaike. Nós consideramos um conjunto de modelos candidatos contendo quatro tipos de modelos de regressão simples: modelo de efeito de habitat; modelos de efeito de tipos de matriz; modelo de efeito da rodovia; e, modelos de referência (intercepto e distância da faixa de influência). Quase 300 atropelamentos e 70 espécies foram registradas. Proximidade do rio e cobertura da vegetação herbácea, ambos modelos de efeito da matriz, foram associadas à maioria dos grupos de vertebrados atropelados. Matriz foi mais relevante do que habitat para prever atropelamentos de vertebrados. A associação entre proximidade do rio e atropelamentos indica que rios podem ser a rota preferencial para a maioria das espécies. Nós discutimos medidas de mitigação multi-espécies e implicações para a ecologia do movimento e estratégias de conservação.

ABSTRACT

Neste trabalho estudou-se a reação de maracujazeiro amarelo 'Maguari' e 'Afruvec' ao fitonematoide Meloidogyne incognita raça 3, em casa-de-vegetação. Adotou-se o delineamento inteiramente casualizado, com três tratamentos (Maguari, Afruvec e Tomateiro cv. Rutgers) e quatro repetições, sendo a parcela constituída por um vaso contendo uma planta. Após seis meses, avaliou-se o índice de galhas e de massa de ovos nas cultivares de maracujazeiro amarelo e no tomateiro cv. Rutgers. A classificação da resistência ao fitonematoide foi feita utilizando o critério do fator de reprodução (FR). A 'Maguari' apresentou zero de índice de galhas e de massa de ovos, enquanto que 'Afruvec' mostrou baixo índice de galhas e massa de ovos comparativamente com o tomateiro cv. Rutgers. De acordo com o FR, a 'Maguari' enquadrou-se como imune ao nematoide, sendo a 'Afruvec' resistente e o tomateiro cv. Rutgers como suscetível.


This study concerned the reaction of yellow passion fruit 'Maguary' and 'Afruvec' to the phytonematode Meloidogyne incognita race 3 in greenhouse conditions. An entirely randomized experimental design with 3 treatments ('Maguary', 'Afruvec', and tomato cv. 'Rutgers') and 4 repetitions was used, each plot consisting of 1 vase containing 1 plant. After 6 months, an evaluation was made of the index of galls and egg mass in the yellow passion fruit varieties and in the tomato cv. 'Rutgers'. The classification of resistance to the phytonematode was made by criterion of the reproduction factor (RF). 'Maguary' presented a zero index of galls and egg mass, while 'Afruvec' showed a low index of galls and egg mass in relation to the tomato cv. Rutgers. According to the RF, 'Maguary' was characterized as immune to the phytonematode, while 'Afruvec' was resistant, and the tomato cv. 'Rutgers' was susceptible.

ABSTRACT

O objetivo do presente trabalho foi verificar o comportamento do maracujazeiro amarelo, variedade Afruvec, ante uma população de Fusarium solani, obtida desse mesmo hospedeiro. O delineamento adotado foi o de blocos ao acaso, contendo dez tratamentos (nove isolados e tratamento testemunha), com quatro repetições, sendo cada parcela representada por um vaso contendo uma planta. Um disco do meio de cultura, colonizado com cada isolado do fungo, foi inoculado no colo ferido das plantas da variedade Afruvec, dois meses após a semeadura. Avaliou-se a patogenicidade, a incidência (número de plantas mortas) e a severidade da doença (comprimento da lesão no colo), até os sessenta dias após a inoculação. A variedade Afruvec foi suscetível ao fungo e apresentou variabilidade quanto à incidência e severidade da doença diante dos diferentes isolados. A população do fungo apresentou variabilidade em relação à agressividade. Com a evidência de diversidade genética na população do fungo, recomenda-se, também, nos testes de seleção de materiais ao patógeno, a avaliação desses materiais em diferentes localidades com histórico da doença ou inoculação com uma mistura de isolados do fungo, a fim de se conhecer a resistência ampla do genótipo ao patógeno.


The objective of the present work was to verify the behavior of yellow passion fruit, Afruvec variety, in relation to a population of Fusarium solani, obtained from this crop. The experimental delineation was random blocks, containing 10 treatments [9 isolates and 1 control treatment], with 4 repetitions, each plot being represented by a vase containing a plant. A disk of culture medium colonized by each isolate of the fungus was inoculated in the wounded collar region of the plants of the Afruvec variety two months after sowing. The appraised parameters were: the pathogenicity, the incidence (number of dead plants) and the severity of the disease (length of the lesion in the collar region), until 60 days after inoculation. The Afruvec variety was susceptible to the fungus and also presented variability as to the severity of the disease and incidence in relation to the different isolates. The population of the fungus showed variability in regard to aggressiveness. In light of the evidence of genetic diversity in the F. solani population, it is also suggested, in the tests of selection of materials to the pathogen, that these materials should be evaluated in different places with a history of the disease or inoculation with a pool of isolates of the fungus, in order to know the wide resistance of the genotype to the pathogen.

ABSTRACT

Idosos utilizam elevado número de medicamentos, apresentando alto potencial para desenvolver interações medicamentosas. Objetivou-se verificar o perfil de utilização de medicamentos e conhecer possíveis interações medicamentosas em idosos acompanhados pelo Programa de Atenção ao Idoso (PAI) da Unijuí. Os dados foram coletados em julho de 2009. Classificaramse os medicamentos no sistema Anatomical Therapeutic Chemical e possibilidades de interações segundo Drug Interaction Facts. De março/2008 até julho/2009 o PAI atendeu 31 idosos, estando 16 em acompanhamento, os quais apresentaram média de 78,4 ± 6,8 anos e utilizaram 83 medicamentos, com média de 5,2 ± 3,7/ idoso. Os fármacos mais prevalentes foram os que atuam no aparelho cardiovascular, no sistema nervoso e para o trato alimentar e metabolismo. Verificaram-se 36 possíveis interações entre 9 pacientes, com média de 4/idoso. O fármaco mais envolvido foi digoxina. Quanto a classificação, 4 apresentaram nível de significância 1, dez nível 2, cinco nível 3, sete nível 4 e dez nível 5. O número de possíveis interações verificadas foi expressivo, entretanto nem todos os idosos apresentarão reações relacionadas às interações, mas apresentaram o risco. Portanto, é importante que prescritores conheçam a influência de um fármaco sobre outro. Seria necessário treinamento intensivo para intervenção farmacêutica, sendo o relacionamento com o médico indispensável.


Elderly people take a large number of medicines, entailing a high risk of developing drug interactions. The aim was to study the profile of medicines prescribed and the possible drug interactions in the public Elderly Care Program (PAI) run at Unijuí, a university in south Brazil. The data were collected in July 2009. The Anatomical Therapeutic Chemical (ATC) Classification System was used to classify medicines, while the potential interactions were classified with the aid of Drug Interaction Facts. Between March 2008 and July 2008, the PAI attended 31 elderly patients, of whom 16 were monitored, with a mean age of 78.4 ± 6.8 years. This group received 83 medicines, making an average of 5.2 ± 3.7 medicines/patient. The most prevalent drugs were those acting on the cardiovascular system, nervous system, digestive tract and metabolism. There were 36 possible interactions in 9 patients, an average of 4 interactions per patient. The drug most frequently involved was digoxin. The interactions were classified as follows: 4 at level 1, 10 at level 2, 5 at level 3, 7 at level 4 and 10 at level 5. This number of possible interactions is considerable; although not all elderly patients show the effects of the drug interactions, they do run the risk. Therefore, it is highly important that prescribers are familiar with the drug interactions. For the pharmacist to help the patient, intensive training for pharmaceutical intervention and a good relationship with the doctor are indispensable.

ABSTRACT

O objetivo do estudo foi determinar a prevalência da farmácia caseira, conhecer os medicamentos que a compõem, os locais destinados ao armazenamento e descarte. Realizou-se estudo transversal junto a famílias do bairro Luiz Fogliatto, Ijuí, RS, cadastradas na Unidade Básica de Saúde deste bairro. As entrevistas foram realizadas nos domicílios de junho a agosto de 2008. Dentre 640 famílias, foram visitadas 321, das quais 91,59% possuíam medicamentos em casa. Encontraram-se 1.234 medicamentos, com predomínio dos atuantes no sistema nervoso (27,28%). A cozinha foi o principal local de armazenamento. Foram encontrados medicamentos vencidos em 17 residências, predominando o descarte no lixo (56,87%). Não foi encontrada legislação que regulamente o descarte de medicamentos em nível domiciliar. O conhecimento quanto ao tema abordado ainda é restrito e impede sua adequada organização em nível domiciliar. O farmacêutico deve orientar quanto ao armazenamento e descarte, capacitando os Agentes Comunitários de Saúde, visando evitar a exposição da população a riscos, assim como a contaminação do meio ambiente.


The aim of this study was to determine the prevalence of household stocks of medicine, to know which medicines are stocked in the home and the places where they are stored and discarded. A cross-sectional survey was conducted with families from the Luiz Fogliatto neighborhood of Ijuí city (RS), registered at the neighborhood Health Service clinic. The interviews were carried out at home in June to August, 2008. There are 640 families in the neighborhood and 321 were visited, of which 91.59% had some medicines at home. In all, 1234 medicines were found, mostly those that act on the nervous system (27.28%). The kitchen was the main place used to store medicines. Expired medicines were found in 17 residences, and the main disposal route was in the common garbage (56.87%). No legislation was found that regulates the disposal of household medicines. Knowledge on storage and disposal of medicines is restricted and does not suffice for its proper organization at home. The pharmacist should educate the patient about storage and disposal and capacitate Community Health Agents, in order to avoid exposure of the public to risks, as well as contamination of the environment.

ABSTRACT

Pharmacological evidence indicates that the basolateral nucleus of the amygdala (BLA) is involved in the mediation of inhibitory avoidance but not of escape behavior in the elevated T-maze test. These defensive responses have been associated with generalized anxiety disorder (GAD) and panic disorder, respectively. In the present study, we determined whether the BLA plays a differential role in the control of inhibitory avoidance and escape responses in the elevated T-maze. Male Wistar rats (250-280 g, N = 9-10 in each treatment group) were pre-exposed to one of the open arms of the maze for 30 min and 24 h later tested in the model after inactivation of the BLA by a local injection of the GABA A receptor agonist muscimol (8 nmol in 0.2 æL). It has been shown that a prior forced exposure to one of the open arms of the maze, by shortening latencies to withdrawal from the open arm during the test, improves the escape task as a behavioral index of panic. The effects of muscimol in the elevated T-maze were compared to those caused by this GABA agonist in the avoidance reaction generated in the light/dark transition test. This defensive behavior has also been associated with GAD. In the elevated T-maze, intra-BLA injection of muscimol impaired inhibitory avoidance (control: 187.70 ± 14.90 s, muscimol: 37.10 ± 2.63 s), indicating an anxiolytic effect, without interfering with escape performance. The drug also showed an anxiolytic effect in the light/dark transition test as indicated by the increase in the time spent in the lighted compartment (control: 23.50 ± 2.45 s, muscimol: 47.30 ± 4.48 s). The present findings point to involvement of the BLA in the modulation of defensive responses that have been associated with GAD.

ABSTRACT

Mechanical ventilation with high tidal volumes (V T) has been shown to induce lung injury. We examined the hypothesis that this procedure induces lung injury with inflammatory features. Anesthetized male Wistar rats were randomized into three groups: group 1 (N = 12): V T = 7 ml/kg, respiratory rate (RR) = 50 breaths/min; group 2 (N = 10): V T = 21 ml/kg, RR = 16 breaths/min; group 3 (N = 11): V T = 42 ml/kg, RR = 8 breaths/min. The animals were ventilated with fraction of inspired oxygen of 1 and positive end-expiratory pressure of 2 cmH2O. After 4 h of ventilation, group 3, compared to groups 1 and 2, had lower PaO2 [280 (range 73-458) vs 517 (range 307-596), and 547 mmHg (range 330-662), respectively, P<0.05], higher wet lung weight [3.62 ± 0.91 vs 1.69 ± 0.48 and 1.44 ± 0.20 g, respectively, P<0.05], and higher wet lung weight/dry lung weight ratio [18.14 (range 11.55-26.31) vs 7.80 (range 4.79-12.18), and 6.34 (range 5.92-7.04), respectively, P<0.05]. Total cell and neutrophil counts were higher in group 3 compared to groups 1 and 2 (P<0.05), as were baseline TNF-alpha concentrations [134 (range <10-386) vs 16 (range <10-24), and 17 pg/ml (range <10-23), respectively, P<0.05]. Serum TNF-alpha concentrations reached a higher level in group 3, but without statistical significance. These results suggest that mechanical ventilation with high V T induces lung injury with inflammatory characteristics. This ventilatory strategy can affect the release of TNF-alpha in the lungs and can reach the systemic circulation, a finding that may have relevance for the development of a systemic inflammatory response

ABSTRACT

En Setiembre de 1988 se realizó un estudio epidemiológico sobre Bartonelosis en los distritos de Masin, Rahuapampa, Huachis, Chaná, Pontó y Huachi en el valle del Puchka, provincia de Huari, Ancash. Se encuestó a 208 pobladores, detectándose entre ellos 7 casos activos de Bartonelosis. A todos se les tomó una muestra de sangre para frotises, hemocultivos y serología. En los 201 personas asintomáticas, se encontró a 77 (38.3 por ciento) portadores asintomáticos de Bartonella bacilliformis. Todas las muestras fueron positivas a la serología teniendo el 91.4 por ciento de la población títulos que oscilaron entre 1/80 y 1/320. Un 12.5 por ciento refirió antecedentes de la enfermedad bartonelósica. Entre los casos clínicos, 6 estuvieron en la fase eruptiva y uno en la fase hemática. Alguno de los casos clínicos y de los portadores se encontraron a más de 3,000 metros de altitud. Se observa que los portadores están en mayor porcentaje entre los que refieren antecedentes y en altitudes más bajas.

ABSTRACT

1. An enzyme-linked immunosorbent assay was used to determine the phospholipid specificity of antibodies in sera from 35 syphilis patients. 2. Based on the cross-reaction obtained aginst a mixture of cardiolipin, phosphatidylcholine and holesterol that is standard for flocculation tests according to the Venereal Disease Research Laboratory (CECON, Säo Paulo, Brazil), all 35 patients tested positive for antibodies of the IgG class whereas 13 (37%) also had IgM antibodies for the same mixture of lipids. IgG antibodies to cardiolipin were demonstrated in 2 patients (6%) and IgM antibodies in 5 (15%). Significant levels of IgG anti-phosphatidylcholine were detected in 3 patients (9%) and IgM antibodies in 4(11%). IgG anti-phosphatidylethanolamine antibodies were found in 1 patient (3%) and IgM antibodies in 3(9%). Antibody binding to cardiolipin plus cholesterol or cardiolipin plus phosphatidycholine was as effective as when the standard mixture of all 3 lipids was used. 3. A comparison with serum from systemic lupus erythematosus patients and inhibition studies using liposomes o cardiolipin or the mixture of 3 lipids suggests that there are at least 3 groups of anticardiolipin antibodies
