ABSTRACT

Phubbing is defined as ignoring other individuals by using a mobile phone during a face-to-face conversation. The Phubbing Scale (PS) was developed to assess this practice. In this study, we analyze the psychometric properties of the 8-item version of the PS (PS-8) in the Portuguese population, providing validity evidence based on internal structure and on relationships with other variables, and examining item properties, reliability, and measurement invariance across gender. Participants were 391 Portuguese adults (132 men, 259 women) who completed a battery of questionnaires. Confirmatory factor analysis yielded satisfactory goodness-of-fit indices for the two-factor structure (communication disturbance and phone obsession), which was invariant across gender. Item homogeneity and reliability of factor scores (McDonald's omega) were satisfactory. Validity evidence based on relationships with other variables was provided by positive associations with time spent on the Internet on weekdays and at the weekend, time spent on social networking sites, number of social networks used, Internet addiction, problematic mobile phone use, Facebook intrusion, fear of missing out, and depression. These associations show the addictive component of phubbing and its relationship with mental health. The PS-8 is a short and easy-to-administer scale with adequate psychometric properties for measuring phubbing in the Portuguese population. (AU)

ABSTRACT

Tectona grandis L.f. es una especie forestal de madera dura que, a pesar de no ser nativa de América, su plasticidad de adaptación ha permitido que en Ecuador se establezcan plantaciones intensivas con fines de exportación. Una compleja enfermedad con características de marchitez vascular está matando miles de árboles de diferentes edades en el país. Se planteó conocer el agente fitopatógeno causante de la patogénesis y muerte de los árboles. Se aislaron los hongos Fusarium sp. y Ceratocystis fimbriata Ellis & Halst. desde árboles enfermos. A nivel de invernadero se plantearon los postulados de Koch, para el efecto 30 plantas de T. grandis de cuatro meses de edad por cada tratamiento, se inocularon con los microrganismos como se describe a continuación: T1= C. fimbriata, T2 = Fusarium sp., T3 = C. fimbriata + Fusarium sp., T4 = agar-agar (control). Se empleó un diseño completo al azar (DCA) y las plantas se evaluaron a los 45 días después de inoculadas. Los tratamientos C. fimbriata, y C. fimbriata + Fusarium sp., mostraron mayores volúmenes aparentes de necrosis, con 1.52 cm3 y 1.93 cm3, y plantas muertas por la infección durante el tiempo de evaluación, mientras que Fusarium sp. mostró baja o nula patogenicidad y comportamiento similar al control, con 0.27 cm3 y 0.16 cm3 respectivamente. Estos resultados sugieren que el agente causal de la enfermedad de marchitez vascular en T. grandis es C. fimbriata y sería el primer reporte del fitopatógeno atacando teca en Ecuador. (AU)


Tectona grandisL.f. it is a hardwood forest species, which despite not being native to America, its adaptive plasticity has allowed intensive plantations to be established for export purposes in Ecuador. A complex disease with characteristics of vascular wilt is killing thousands of trees of different ages in the country. It was proposed to know the phytopathogenic agent causing the pathogenesis and death of the trees. Fusarium sp. andCeratocystis fimbriata Ellis & Halst. were isolated from diseased trees. At the greenhouselevel, Koch's postulates were proposed, for the effect 30 four month old T. grandisplants for each treatment were inoculated with the microorganisms as described below: T1 = C. fimbriata, T2 = Fusariumsp ., T3 = C. fimbriata+ Fusariumsp., T4 = agar-agar (control). A complete randomized design (DCA) was used and the plants were evaluated 45 days after inoculation. The treatments C. fimbriata, and C. fimbriata+ Fusariumsp. showed higher apparent volumes of necrosis, with 1.52 cm3and 1.93 cm3, and plants killed by the infection during the evaluation time, while Fusariumsp. showed low or no pathogenicity and behavior similar to the control, with 0.27 cm3and 0.16 cm3respectively. These results suggest that the causative agent of vascular wilt disease in T. grandisis C. fimbriataand it would be the first report of phytopathogen attacking teak in Ecuador. (AU)

ABSTRACT

In broiler breeder roosters, the weight of the testes is positively associated with daily sperm production and fertility. In birds, the testes are located in the coelomic cavity, not being accessible to reproductive evaluation as mammalian testes. The reproductive evaluation of roosters is based on phenotypic traits. Any changes on testes will be reflected on fertility levels. The aim of this paper was to evaluate the potential of association of phenotypic traits as body weight (BW), comb scores (COS), cloaca scores (CLS) and feet scores (FS) with testicular morphometric parameters in adult Cobb® Mx roosters in two ages (25 and 45 weeks of age). The low BW roosters had lower testes weight (TW), smaller seminiferous tubule diameter (STD) and lower comb and cloaca scores than the medium and high BW roosters (P≤0.05). Heavy roosters had the highest COS and bigger seminiferous epithelium height (SEH). There was no statistical difference between the BW categories in FS and volumetric proportion of seminiferous tubule (ST) and interstitial tissue (IT). Considering the age effect, roosters with 45 weeks of age had lower TW and ST than 25-week roosters. Positive, moderate and significant correlation was found between testes weight and phenotypic characteristics as BW, COS and CLS in 45week roosters. A positive, moderate and significant correlation was found between body weight and histologic testicular characteristics as STD and SHE in both evaluated ages. In conclusion, there is a regression in the testes weight with age and it is more intense in Cobb® Mx roosters with lower BW. Furthermore, it is concluded that the BW positively influences the testes weight and histological quality of the testes. COS and CLS can be used with moderate potential prediction to identify roosters with low testes weight at 45 weeks of age.(AU)


Em galos de matriz pesada sabe-se que o peso dos testículos pode ser associado positivamente com a produção diária de espermatozoides e que alterações nos testículos irão refletir na fertilidade. Nas aves, os testículos estão localizados dentro da cavidade celomática, e, portanto, não são acessíveis para exame andrológico direto, como em mamíferos. A avaliação reprodutiva de galos se baseia principalmente em características fenotípicas. Buscou-se avaliar o potencial de associação de alguns parâmetros fenotípicos, como peso corporal (PC), escores de crista (ECR), escores de cloaca (ECL) e escores de pés (EP), com parâmetros morfológicos de testículos em galos Cobb® Mx em duas idades (25 e 45 semanas de idade). Galos leves apresentaram menor peso testicular (PT), menor diâmetro de túbulo seminífero (DT), e menores ECR e ECL que galos médios e pesados (P≤0.05). Galos pesados apresentaram os maiores ECR e maiores valores para altura do epitélio seminífero (AE), e DT. Não houve diferença estatisticamente significativa entre as categorias de peso para escores de pé e proporções de túbulo seminífero (TS) e interstício (INT). Considerando-se o efeito da idade, galos com 45 semanas de idade apresentaram menores PT e TS que galos com 25 semanas de idade. Correlação positiva, moderada e significativa foi encontrada entre peso de testículo e características fenotípicas como ECR, ECL e PC em galos de 45 semanas de idade. Foi encontrada correlação positiva, moderada e significativa entre PC e características testiculares como DT e AE nas duas idades avaliadas. Conclui-se que em galos Cobb® Mx ocorre regressão do testículo com o avanço da idade, e ela é mais intensa em galos com menor peso corporal. Conclui-se que o PC tem influência positiva no peso e índices histomorfométricos dos testículos, e que escores de crista e de cloaca podem ser utilizados com potencial moderado de predição para identificar galos com baixo peso de testículos em galos com 45 semanas de idade.(AU)

ABSTRACT

Este estudo foi conduzido com o objetivo de determinar o melhor teor de substituição da proteína do farelo de algodão pela proteína da torta de girassol em dietas para cordeiros Santa Inês, por meio da avaliação do consumo, ganho de peso, conversão alimentar e medidas morfométricas. Foram confinados, por 60 dias, 30 cordeiros da raça Santa Inês, machos inteiros, com idade e peso médio no início do experimento de 80 dias e 21,45±2,16kg, respectivamente. O delineamento experimental foi completamente casualizado, sendo os animais divididos em 5 tratamentos, com 6 repetições por tratamento, de acordo com a quantidade de proteína do farelo de algodão substituída pela proteína da torta de girassol (0, 20, 40, 60 e 80% de substituição). As variáveis peso final, consumo de matéria seca e conversão alimentar não foram afetadas pelas dietas experimentais, embora o ganho médio diário tenha sido inferior para as dietas com maior teor de torta de girassol. Para os parâmetros de consumo, verificou-se diferença apenas no consumo de extrato etéreo em relação ao peso metabólico (g/kg PV0,75), em que cordeiros recebendo dieta com maior teor de torta de girassol ingeriram maiores quantidades de extrato etéreo. Em relação às medidas morfométricas, houve decréscimo linear da altura de dorso e largura de garupa com a inclusão da torta de girassol na dieta. A substituição da proteína do farelo de algodão pela proteína da torta de girassol afetou negativamente o ganho de peso de cordeiros Santa Inês em confinamento. Porém, teve pouca ou nenhuma influência nos parâmetros de consumo e nas medidas morfométricas in vivo.(AU)


This study was conducted with the aim to determine the optimal level of protein replacement of cottonseed meal protein by sunflower cake in diets for Santa Inês lambs, through the evaluation of consumption, weight gain, feed conversion and morphometric measurements. Thirty Santa Inês lambs, bulls, with age and weight at the beginning of the experiment of 80 days and 21.45±2.16kg, respectively, were confined for 60 days. A completely randomized experimental design was used, where the animals were divided into 5 treatments with 6 replicates per treatment. For the treatments, the protein from the cottonseed meal was replaced by the protein of the sunflower cake (0, 20, 40, 60 and 80% of substitutions). For morphometric determinations, the following measurements were taken: pre-slaughter body length, leg length, leg perimeter, height of the dorsum; hip height; chest girth, hip width and chest width. Final weight, dry matter intake and feed conversion were not affected by the experimental diets, although the average daily gain was lower for diets with higher content of sunflower cake. For consumption parameters, there was a difference only in the consumption of ether extract in relation to metabolic weight (g/kg PV 0, 75), where lambs receiving diets with higher levels of sunflower cake ingested larger amounts of ether extract. Regarding the morphometric measurements, there was a linear decrease of the height of the dorsum and hip width with the inclusion of sunflower cake in the diet. The replacement of cottonseed meal protein by sunflower cake protein negatively affected the weight gain of Santa Inês lambs. However, it affected little or nothing the parameters of consumption and in vivo morphometric measurements.(AU)

ABSTRACT

Analisaram-se as qualidades física, química e sensorial, bem como o perfil de ácidos graxos da carne de fêmeas suínas alimentadas com dietas com concentrações crescentes de ractopamina. Foram utilizadas 468 fêmeas, com peso inicial de 84,77±7,20kg, alojadas em 36 baias e alimentadas com dietas contendo 0, 5, 10 ou 15mg de ractopamina/kg. Após o período de 28 dias, dois animais de cada baia, depois de passarem por 15 horas de jejum sólido, foram abatidos. Uma amostra do músculo Longissimus da meia carcaça direita foi colhida para se avaliar as características de qualidade da carne. Não houve efeito (P>0,05) da adição de ractopamina às dietas sobre o pH, capacidade de retenção de água, força de cisalhamento, cor e oxidação lipídica da carne. Observou-se efeito quadrático (P<0,05) para perdas por cocção da carne, e não foi observada diferença (P>0,05) na análise sensorial da carne. Também não foi observado efeito (P>0,05) sobre a composição em ácidos graxos e sobre a relação entre ácidos graxos saturados:insaturados. A adição de até 15mg de ractopamina/kg de dieta não altera as características físicas, sensoriais e o perfil de ácidos graxos da carne de fêmeas suínas abatidas com 110kg de peso.


A study was conducted to evaluate the physical, chemical and sensorial quality and fat acids profile of meat from gilts fed diets containing increasing concentration of ractopamine. A total of 468 gilts with initial weight of 84.77±7.20kg were allotted into 36 pens and fed diets containing 0, 5, 10 or 15mg of ractopamine/kg. After an experimental period of 28 days, two animals from each pen were chosen and slaughtered after 15 hours of fasting. A sample of the Longissimus muscle was collected to evaluate the quality of the pork meat. There was no effect (P>0.05) of ractopamine inclusion in pH, water holding capacity, shear force, color and lipid oxidation. However, a quadratic trend was observed (P<0.05) for cooking loss by increasing concentration of ractopamine in diets. For sensorial analysis of the Longissimus muscle, no differences were noted (P>0.05). No effects were observed (P>0.05) for fat acids profile and saturated and unsaturated fat acids ratio. In conclusion, the increase of up to 15mg of ractopamine/kg concentration in the diet does not change the physical and sensorial characteristics and the fat acids profile of meat from gilts slaughtered at 110kg of body weight.

ABSTRACT

Neural mechanisms involved in sleep and wakefulness generation are widely distributed in the central nervous system. Current models emphasize the pivotal role of the hypothalamus incontrolling the activation and inhibition of the ascending activating system and thlamo-cortical networks during wakefulness and restorative sleep respectively. The restorative properties of sleep, the duration and the timing of sleep occurrence is determined by at least two families of processes; (i) circadian rhythms generated at the hypothalamic pacemaker, that favorssleep and wakefulness at determined phases of the day; and (ii) homeostatic mechanisms that maintain the adequate daily sleep quotas, by compensating sleep debts and excesses. It is a current focus of clinical and basic research the effect of transient or chronic disruption of sleep architecture on performance and wellbeing.

ABSTRACT

The development of new MRI technologies has favoured the use of sequences that significantly improve the spatial resolution of this imaging method, thus yielding thin-section images that allow volumetric analysis. We present our experience at Clínica Vespucio related to a routine knee MRI protocol, performed on 45 patients who underwent conventional proton density-weighted spin-echo sequence (PDFS) 3-mm section thickness along with proton density-weighted sequence of 1.2- mm thin-section, both with fat suppression technique. In most cases, the thin-section PDFS allows a better anatomical characterization of lesions, particularly meniscal and condral injuries, with a minimum increase in image acquisition time.


El desarrollo de nuevas tecnologías en resonancia magnética ha favorecido el uso de secuencias que mejoran significativamente la resolución espacial del método, obteniendo imágenes de cortes finos que permiten análisis volumétrico. Se presenta la experiencia en Clínica Vespucio en un protocolo rutinario de estudio de rodilla, con evaluación de 45 pacientes consecutivos a los que se les realizó secuencia tradicional de densidad protónica con saturación grasa (DPFS) de corte grueso (3 mm) y secuencia DPFS volumétrica de corte fino (1,2 mm). En la mayoría de los casos es posible realizar mejor caracterización anatómica de las lesiones, principalmente meniscales y condrales, con un mínimo aumento en el tiempo de estudio.

ABSTRACT

Viruses depend on cell metabolism for their own propagation. The need to foster an intimate relationship with the host has resulted in the development of various strategies designed to help virus escape from the defense mechanisms present in the host. Over millions of years, the unremitting battle between pathogens and their hosts has led to changes in evolution of the immune system. Snake venoms are biological resources that have antiviral activity, hence substances of significant pharmacological value. The biodiversity in Brazil with respect to snakes is one of the richest on the planet; nevertheless, studies on the antiviral activity of venom from Brazilian snakes are scarce. The antiviral properties of snake venom appear as new promising therapeutic alternative against the defense mechanisms developed by viruses. In the current study, scientific papers published in recent years on the antiviral activity of venom from various species of snakes were reviewed. The objective of this review is to discuss the mechanisms of resistance developed by viruses and the components of snake venoms that present antiviral activity, particularly, enzymes, amino acids, peptides and proteins.

ABSTRACT

A better understanding of dendritic cell (DC) involvement in responses to haptenic drugs is needed, because it represents a possible approach to the development of an in vitro test, which could identify patients prone to drug allergies. There are two main DC subsets: plasmacytoid DC (pDC) and myeloid DC (mDC). β-lactams form hapten-carrier conjugates and may provide a suitable model to study DC behavior in drug allergy reactions. It has been demonstrated that drugs interact differently with DC in drug allergic and non-allergic patients, but there are no studies regarding these subsets. Our aim was to assess the functional changes of mDC and pDC harvested from an amoxicillin-hypersensitive 32-year-old woman who experienced a severe maculopapular exanthema as reflected in interleukin-6 (IL-6) production after stimulation with this drug and penicillin. We also aim to demonstrate, for the first time, the feasibility of this method for dendritic cell isolation followed by in vitro stimulation for studies of drug allergy physiopathology. DC were harvested using a double Percoll density gradient, which generates a basophil-depleted cell (BDC) suspension. Further, pDC were isolated by blood DC antigen 4-positive magnetic selection and gravity filtration through magnetized columns. After stimulation with amoxicillin, penicillin and positive and negative controls, IL-6 production was measured by ELISA. A positive dose-response curve for IL-6 after stimulation with amoxicillin and penicillin was observed for pDC, but not for mDC or BDC suspension. These preliminary results demonstrate the feasibility of this methodology to expand the knowledge of the effect of dendritic cell activation by drug allergens.

ABSTRACT

Crotalus durissus cumanensis, a rattlesnake endemic to Colombia and Venezuela, is considered one of the most lethal snake species in Latin America. The aim of the present study was to compare the protein content and biological activity of the venom obtained from eight specimens of C. durissus cumanensis, namely two adults from different localities of Colombia and six offspring born in captivity. Protein profiles of crude venoms were analyzed by SDS-PAGE and RP-HPLC, and biological activities were evaluated for lethality, edema, defibrination, hemolytic and coagulant activities to assess individual venoms of adults and a pool of young snake venoms. Transient edema appeared rapidly after venom inoculation, whereas hemorrhagic effect was not observed. Differences in protein profiles, lethality, hemolytic, coagulant and defibrinating activities between both adult snake venoms were observed; those from the mother snake exhibited higher activities. Venoms from young snakes were similar to the one obtained from the mother, but the coagulant effect was stronger in offspring venoms. Notably, biological effects of the father snake venom were not comparable to those previously described for C. durissus cumanensis from Venezuela and C. durissus terrificus from Brazil, confirming the high variability of the venom from Crotalus species.

ABSTRACT

INTRODUÇÃO: Em nossa sociedade, temos observado uma oferta cada vez maior de modelos, cores, estilos, altura e diversos tipos de salto. OBJETIVO: Avaliar se o uso de calçados de salto alto influencia nas alterações posturais com base em um conjunto de variáveis mensuradas por meio da fotogrametria computadorizada. MÉTODOS: Vinte indivíduos que utilizam salto alto com freqüência (grupo 1) e 20 indivíduos que utilizam salto alto esporadicamente (grupo 2) foram fotografados no plano frontal anterior e sagital em três momentos: a) sem utilização de calçado, b) utilizando salto agulha e c) utilizando salto plataforma, sendo estas fotografias aleatorizadas e analisadas por um experimentador cego por meio da fotogrametria. A análise estatística foi realizada a partir da análise de variância em esquema fatorial 2x3, ou seja, comparando-se a freqüência do uso de salto com o tipo de calçado, com 5 por cento de significância. RESULTADOS: Apenas o ângulo protrusão da cabeça apresentou diferença quando comparados grupo 1 e 2 (p<0,01). O efeito do tipo de calçado ocorreu na variável alinhamento do joelho direito, sendo que houve diferença apenas entre o sapato agulha e os pés descalços (p=0,03); também para a variável ângulo tibiotársico, o efeito esteve presente em todos os tipos de calçado. Os demais ângulos avaliados não apresentaram diferenças entre a freqüência no uso de salto e os outros tipos de sapato. CONCLUSÕES: A freqüência do uso de salto e o tipo de salto praticamente não modificam a postura estática avaliada pela fotogrametria.


INTRODUCTION: In our society, it is observed an increasing number of models, colors, styles, heights and types of high heels. OBJECTIVE: To evaluate whether the use of high heel shoes results in postural changes, based on a set of variables measured through computerized photogrammetry. METHODS: Twenty individuals who often used high heels (group 1) and 20 individuals who only used high heels sporadically (group 2) were photographed in the frontal and sagittal planes at three conditions: a) without using footwear; b) using stiletto heels; and c) using high platform heels. These photographs were randomized and analyzed by a blinded examiner, by means of photogrammetry. Statistical analysis was performed, using a 2x3 factorial analysis of variance to compare the frequency of high heel use with the type of shoe, at the 5 percent significance level. RESULTS: Only the head protrusion angle showed a difference between groups 1 and 2 (p<0.01). The effect of the type of shoe observed in the alignment of the right knee, which only showed a difference between stiletto heels and barefoot (p=0.03). For the tibiotarsal angle variable, the effect was also observed for all types of footwear. The other angles evaluated did not present any differences regarding the frequency of high heel use and the types of shoe. CONCLUSIONS: The frequency and type of high heel practically did not change the static posture evaluated by photogrammetry.

ABSTRACT

Piplartine {5,6-dihydro-1-[1-oxo-3-(3,4,5-trimethoxyphenyl)-2-propenyl]-2(1H)pyridinone} and piperine {1-5-(1,3)-benzodioxol-5-yl)-1-oxo-2,4-pentadienyl]piperidine} are alkaloid amides isolated from Piper. Both have been reported to show cytotoxic activity towards several tumor cell lines. In the present study, the in vivo antitumor activity of these compounds was evaluated in 60 female Swiss mice (N = 10 per group) transplanted with Sarcoma 180. Histopathological and morphological analyses of the tumor and the organs, including liver, spleen, and kidney, were performed in order to evaluate the toxicological aspects of the treatment with these amides. Administration of piplartine or piperine (50 or 100 mg kg-1 day-1 intraperitoneally for 7 days starting 1 day after inoculation) inhibited solid tumor development in mice transplanted with Sarcoma 180 cells. The inhibition rates were 28.7 and 52.3 percent for piplartine and 55.1 and 56.8 percent for piperine, after 7 days of treatment, at the lower and higher doses, respectively. The antitumor activity of piplartine was related to inhibition of the tumor proliferation rate, as observed by reduction of Ki67 staining, a nuclear antigen associated with G1, S, G2, and M cell cycle phases, in tumors from treated animals. However, piperine did not inhibit cell proliferation as observed in Ki67 immunohistochemical analysis. Histopathological analysis of liver and kidney showed that both organs were reversibly affected by piplartine and piperine treatment, but in a different way. Piperine was more toxic to the liver, leading to ballooning degeneration of hepatocytes, accompanied by microvesicular steatosis in some areas, than piplartine which, in turn, was more toxic to the kidney, leading to discrete hydropic changes of the proximal tubular and glomerular epithelium and tubular hemorrhage in treated animals.

Metodos: participaram 21 voluntarios (24+-1,9 anos) que tiveram fotografados a face e o corpo todo nos planos frontal anterior, posterior e sagital. Os angulos estudados form tracados nas fotos digitais, a partir de marcadores fixos a pele em varios pontos anatomicos, que sao referencias frequentes na avaliacao postural tradicional. A analise da confiabilidade foi efetuada a partir das medidas angulares de uma mesma foto, obtidas por um unico examinador em duas ocasioes (intra-examinadores) intervaladas por um mes e de uma so medida realizada por um terceiro examinador (interexaminadores). Arepetibilidade do metodo foi analisada pelas medidas angulares tomadas por um examinador em 2 fotos diferentes do mesmo sujeito, realizadas com intervalos de uma semana. O coeficiente de correlacao intraclasse (ICC) foi aplicado com nivel de significancia de 5 por cento. Resultados: O metodo proposto apresenta significativa confiabilidade intra e interexaminadores para a maioria dos angulos estudados. No entanto, a cifose toracica apresentou niveis nao aceitaveis de confiabilidade para a analise inter (ICC=0,603) e intra-examinador (ICC=0,031). Na repetibilidade do metodo, a maioria dos angulos estudados apresentou baixo nivel de confiabildade, exceto pelos angulos de inclinacao do pe direito (ICC=0,863) e triangulos de Talles (esquerdo ICC=0,922 e direito = 0,867). Conclusao: nessas condicoes experimentais a maioria dos valores angulares obtidos pelo metodo proposto apresentou confiabilidade intra e interexaminadores. No entanto, sua repetibilidade e baixa, sugerindo que o metodo e pouco indicado para o acompanhamento de mudancas posturais

ABSTRACT

A repercussão sobre a resposta imune da expressão da agressividade intra-específica diante de um estressor foi investigada em ratos. Aos 90 dias de vida, os animais foram divididos em três grupos: grupo-controle (foram realizadas apenas mensurações imunológicas), choque nas patas (FS) (os animais receberam FS individualmente) e grupo resposta agressiva intra-específica (IAR) (os animais receberam FS e apresentaram IAR). Para as medições imunológicas, amostras de sangue foram coletadas imediatamente, 7 e 15 dias após FS ou IAR. O FS reduziu a quantidade total de leucócitos. Contudo, a agressividade foi acompanhada, além da redução do número de leucócitos, por diminuição de linfócitos e aumento de neutrófilos. Além disso, também foi observada elevação no número de leucócitos associada a aumento na resposta imune humoral uma semana após as IAR. Neste estudo, a expressão da agressividade intra-específica diante de um estressor parece ativar o sistema imune e potencializar a resposta humoral antígeno específica.

ABSTRACT

Objetivo: Evaluar la respuesta terapéutica quirúrgica en pacientes con estenosis de uretra bulbar(EUB) adyacentes al piso perineal, coincidentemente con una estenosis de la uretra péndula(EUP). Material y métodos: Se estudió una población de 15 pacientes con estas características. Se definieron dos grupos según la técnica empleada en la resoluciónde la EUB: Grupo a) 13 pacientes requirieron la realización de una Resección Anastomosis Primaria (RAP). Grupo b) en 2 casos se emplearon técnicas en dos tiempos. La EUP fue resuelta con un colgajo fasciocutáneo longitudinal de piel de pene a lo Orandi o transversal de prepucio. El seguimiento promedio de toda la población fue 4,3 años. Resultados: El 33,33 por ciento de los pacientes tuvieron que ser reintervenidos quirúrgicamente: Grupo a) fueron reintervenidos el 23 por ciento y en el grupo b) el 100 por ciento. Topografía de las recurrencias: Grupo a) en todos los casos involucraba la EUB, Grupo b) se registraron estenosis a nivel de la EUB en un caso y de la boca proximal del Orandi en otro. La plástica que más recurrencia registró fue la RAP. Los tiempos de recurrencia fueron bajos con una media de 3,48 meses (2 a 9 meses). Conclusión: a) La recurrencia observada fue elevada, especialmente en las RAP. b) La recurrencia suele ser temprana y suele requerir resolución quirúrgica, siendo improbable que opciones mínimamente invasivas sean la opción a considerar

ABSTRACT

A inflamação da asma não está limitada às vias aéreas e pode comprometer também o parênquima pulmonar periférico, no entanto, não há estudos na literatura que enfoquem a participação do parênquima pulmonar na asma. Objetivo: Caracterizar o infiltrado inflamatótrio do parênquima peribronquiolar e distal em vítimas de asma fatal, comparando-o ao de outras regiões de vias aéreas e a de tecido pulmonar de não asmáticos. Fragementos de tecido pulmonar obtidos de 20 pacientes com asma fatal e 10 controles, necropsiados no Serviço de verificacão de óbito da capital - São Paulo, foram submetidos a estudo de imuno-histoquímica e marcados com anticorpos anti-proteína básica principal (eosinófilos), anti-triptase (mastócitos), anti-elastase neutrofílica (neutrófilos) e anti-marcadores de superfície de linfócitos (CD3, CD$, CD* e CD20). Foram determinadas as densidades celulares no parênquima pulmonar periférico peribronquiolar e distal e nas áreas interna e externa das vias aéreas de grande e de pequeno calibre. Resultados: A densidade de eosinófilos foi significativamente maior nas duas regiões do parênquima pulmonar de asmáticos comparados aos controles, bem como as vias aéreas (p<0,02). Nos pacientes asmáticos a densidade eosinófilica se mostrou menos no parênquima distal em relação à da área interna da via aérea grande apenas (p<0,01). A densidade dos mastócitos foi maior no parênquima peribronquiolar bem como na área externa das vias aéreas de grande e de pequeno calibre de asmáticos comparados aos controles (p<0.04). Diferenças significativas quanto à densidade de linfócitos se restringiram às vias aéreas de asmáticos comparadas as de controles. Maior densidade de neutrófilos foi observada apenas no parênquima pulmonar de asmáticos (p=0.029). Conclusões: O parênquima pulmonar participa do processo inflamatório na asma fatal com aumento de células efetoras (mastócitos, neutrófilos e eosinófilos). A área externa da via aérea foi a região que melhor diferenciou o asmáticodo controle e com o maior número de diferenças significativas. A inflamação do parênquima peribronquiolar, associado ao da área externa da via áerea pequena, reforça o papel do pulmão distal na patofisiologia da asma.
