ABSTRACT Information on irrigation management is essential for achieving satisfactory results when cultivating the green pepper. The aim of this study, therefore, was to evaluate the effects of water deficit, which varies according to phenological stage, on the production, growth and physiology of a crop of green peppers. The experimental design was completely randomised, with seven treatments, four repetitions, and plots comprising two plants. The treatments consisted of replacing the water demand during phenological phases I, II, III and IV (in terms of percentage ETc): T1 - 100%/I, 100%/II, 100%/III and 100%/IV; T2 - 100%/I, 75%/II, 100%/III and 75%/IV; T3 - 100%/I, 75%/II, 75%/III and 75%/IV; T4 - 100%/I, 75%/II, 75%/III and 50%/IV; T5 - 100%/I, 50%/II, 75%/III and 50%/IV; T6 - 100%/I, 50%/II, 50%/III and 50%/IV; T7 - 100%/I, 50%/II, 50%/III and 25%/IV. The plants were grown in the field under drip irrigation. The following variables were analysed: plant height; stem diameter, leaf area, shoot dry weight, number of fruits per plant, soluble solids, fruit length, fruit diameter, fruit weight, productivity, relative chlorophyll index, gas exchange, and water use efficiency. Compared to T1, management based on T2, T3 and T4 did not reduce expression of the vast majority of the vegetative variables or of gas exchange. The water deficit from T2 can be employed without any significant reduction in productivity and affords water savings of 12.5% in relation to T1. T1 and T2 give the highest values for water use efficiency. Management based on T1 and T2 is therefore recommended for cultivating the green pepper under field conditions.

Resumen La ganadería de traspatio realizada por familias campesinas e indígenas mexicanas forma parte de las estrategias de vida para conseguir la seguridad alimentaria. Con el objetivo de aportar información sobre el manejo productivo del componente pecuario en el traspatio de las familias totonacas se realizó una investigación en la comunidad de Lipuntahuaca, ubicada en el municipio totonaco de Huehuetla, Puebla, en una muestra de 76 familias seleccionadas al azar. Se trabajó con tres grupos de productores y se realizó un análisis de conglomerados, una prueba exacta de Fisher, una prueba de Chi-cuadrada y el cálculo de medias para determinar la varianza y establecer diferencias entre grupos, así como una prueba exacta de Fisher para analizar las variables tenencia de animales y si el productor se considera pobre. Los resultados indican que la tenencia de las especies encontradas en las familias es baja, con 10 aves en promedio, y solo 17% cuenta con cerdos. Se observó que esta actividad contribuye principalmente al autoconsumo, pues el ingreso que obtienen es muy reducido, y debido a la precariedad económica que enfrentan las familias de la comunidad, esta producción constituye una importante fuente de alimentos que juega un papel fundamental en su subsistencia.

Abstract Backyard livestock raising by Mexican peasant and indigenous families is part of the livelihood strategies to achieve food security. With the objective of providing information on the productive management of the livestock component in the backyard of Totonaca families, an investigation was carried out in the community of Lipuntahuaca, located in the Totonaca municipality of Huehuetla, Puebla, in a sample of 76 families selected at random. We worked with three groups of producers and conducted a cluster analysis, Fisher's exact test, a Chi-square test and the calculation of means to determine the variance and establish differences between groups, as well as Fisher's exact test to analyze the variables: animal ownership and whether the producer is considered poor. The results indicate that the number of species owned by the families is low, with an average of 10 birds, and only 17% have pigs. It was observed that this activity contributes mainly to self-consumption, since the income obtained is very low. Due to the economic precariousness faced by the families in the community, this production constitutes an important source of food that plays a fundamental role in their subsistence.

Resumo Este estudo teve como objetivo avaliar a eficácia das células-tronco mesenquimais (CTMs), isoladas ou associadas à dapsona (DAP), no tratamento de feridas dermonecróticas causadas pelo veneno de Loxosceles laeta. Vinte e cinco coelhos machos foram distribuídos em cinco grupos. O controle negativo recebeu água ultrapura (C-), enquanto todos os outros grupos foram injetados com 20 μg de veneno de L. laeta. Após 4 horas, cada grupo recebeu um dos seguintes tratamentos: PBS (C+), DAP, CTMs e DAP + CTMs. Os animais foram avaliados diariamente durante 12 dias, e feitos registros fotográficos para análise da ferida e no 12º dia, foram eutanasiados e, retiradas amostras de pele para análise histológica. Observou-se que a DAP apresentou o melhor percentual de contração da ferida no terceiro dia. Nos tratamentos com CTMs, observou-se uma contração negativa da ferida tanto para as CTMs isoladas, bem como a associação CTMs + DAP em relação ao PBS, possivelmente, pelo aumento da infamação inicial após a aplicação de células-tronco. Isso é devido ao fato de que as CTMs secretam um amplo espectro de moléculas bioativas como citocinas e fatores de crescimento que favorecem a regeneração. Histologicamente, observou-se que os animais de C+ apresentaram extensas áreas de necrose, úlceras, infiltrado neutrofílico, além de mineralização. Houve aumento de deposição de colágeno no tratamento CTMs + DAP, no entanto, a vascularização permaneceu inalterada. Este é o primeiro relato usando CTMs e CTMs + DAP como tratamento para loxoscelismo cutâneo e mais estudos são necessários para determinar seu uso como terapia alternativa para lesões demonecróticas causadas pela aranha Loxosceles.

Abstract This study aimed to evaluate the efficacy of mesenchymal stem cells (MSC), alone or associated with dapsone (DAP), in treating dermonecrotic wounds caused by Loxosceles laeta venom. Twenty-five male rabbits were distributed into five groups. Negative control received ultrapure water (C-), whilst all other groups were injected with 20 μg of L. laeta venom. After 4 hours, each group received one of the following treatments: PBS (C+), DAP, MSC, and DAP+MSC. Animals were evaluated daily and photographic records made for analysis of wound area. Twelve days after, animals were euthanized and skin samples removed for histological analysis. We observed that DAP showed the best percentage of wound contraction at day 3. In the treatments using MSCs, a negative value of wound contraction was observed for the isolated MSCs, as well as a lower contraction value for the association of the MSC + DAP when compared to PBS, probably, by the increase in initial infammation after the application of stem cells, due to the fact that MSCs secrete a broad spectrum of bioactive molecules such as cytokines and growth factors that favor regeneration. Histologically, it was observed that animals of C+ showed extensive areas of necrosis, ulcers, neutrophilic infiltrate, and mineralization. Collagen deposition showed increase in MSC+DAP treatment, however vascularization remained unchanged. This is the first report using MSC and MSC+DAP as a treatment for cutaneous loxoscelism and more studies are needed to determine its use as an alternative therapy for dermonecrotic lesions caused by Loxosceles spider.

ABSTRACT Introduction: Man has acted on bone fractures of the limbs since ancient times, confirming immobilization (reduction-stability) as the basic way of treating the condition, which is presented with the triad of trauma, pain and functional impotence. Objective: The objective of this paper was to organize the presentation of the changes occurred with technological innovations, integrated in the treatment of fractures. Methods: A literature review on fractures is presented here. Articles published in journals indexed by CITMA, books by well-known authors, personal notes of events and surgical activities were reviewed, in order to analyze the selected variables and their historical links with the different stages that marked the new conceptions and modifications, arisen in the use of this type of osteosynthesis we call generations. Variables selected for analysis were fracture reduction, access route for plate placement, surgical procedure, new implant designs, instrumentation, implant metallurgy, and healing consolidation. Constitutive elements of the osteosynthesis surgical procedure: By relating the results obtained and the dates of their implementation, with historical moments and the inclusion of relevant technological innovations, we come to recognize three stages or "generations" and their influence explains the advances in the current conceptions of this approach. First generation: classic, early 20th century. Second generation: compression, post-World War II. Third generation: current, functional, and biological. Conclusions: By relating the results obtained and the dates of their implementation, with historical moments and the inclusion of relevant technological innovations, we come to recognize three stages or "generations" whose influence explains the advances in the current conceptions of this procedure. First generation or classic: at the beginning of the 20th century. Second generation: compression, post-World War II. Third generation: current, functional and biological.

RESUMEN Introducción: El hombre ha actuado sobre las fracturas óseas de los miembros desde tiempos ancestrales, confirmando a la inmovilización (reducción-estabilidad) como la forma básica de tratar la afección, que se le presenta con la tríada: trauma, dolor e impotencia funcional. Objetivo: El objetivo de este trabajo fue organizar la presentación de los cambios que ocurrían con las innovaciones tecnológicas que se incorporaban en el tratamiento de las fracturas. Métodos: Se presenta una revisión de artículos sobre fracturas publicados en revistas indizadas por el CITMA, libros de autores reconocidos, notas personales de eventos y actividades quirúrgicas, con el fin de analizar las variables seleccionadas y sus vínculos históricos con las distintas etapas que marcaron las nuevas concepciones y modificaciones, surgidas en la aplicación de este tipo de osteosíntesis, lo que nominamos Generaciones. Las variables seleccionadas para el análisis fueron: la reducción de la fractura, la vía de acceso para la colocación de la placa, el procedimiento quirúrgico, los nuevos diseños de implantes, el instrumental, la metalurgia de los implantes y la consolidación curativa. Elementos constitutivos del procedimiento quirúrgico de la osteosíntesis. Relacionando los resultados obtenidos y las fechas de su puesta en práctica, con momentos históricos y la inclusión de Innovaciones Tecnológicas de relevancia, llegamos a reconocer tres etapas o “Generaciones” donde la influencia de las mismas, explican los adelantos en las concepciones actuales de este proceder. Primera Generación: Clásica, a principios del siglo XX. Segunda Generación: de Compresión, Post Segunda Guerra Mundial. Tercera Generación: Actual, Funcional, y Biológica. Conclusiones: Relacionando los resultados obtenidos y las fechas de su puesta en práctica, con momentos históricos e inclusión de innovaciones tecnológicas de relevancia, llegamos a reconocer tres etapas o “Generaciones” donde su influencia explica los adelantos en las concepciones actuales de este proceder.

Abstract Agroecological principles crystalize in the productive management of the backyard of Totonac houses, whose practices set nature and humans at the center of their traditional knowledge to produce food. This research was carried out in the community of Lipuntahuaca, municipality of Huehuetla, Puebla, Mexico, located at the heart of the Totonac region, aiming to know the characteristics surrounding the food production for self-consumption in Totonac households. Information was obtained through questionnaires applied to a probabilistic sample in 77 households. The results reveal that the backyard is used for the production of food and medicinal plants as well as for livestock raising (poultry and pigs), mainly intended for family feeding. Besides this, it constitutes an important space for the performance of traditional celebrations related to this ethnic group’s worldview.

Resumen En el manejo productivo del traspatio de las viviendas totonacas se cristalizan principios agroecológicos, cuyas prácticas ponen como centro a la naturaleza y al ser humano con sus conocimientos tradicionales para producir alimentos. Esta investigación se realizó en la comunidad de Lipuntahuaca, municipio de Huehuetla, Puebla, México, ubicado en el corazón de la región totonaca, con el objetivo de conocer las características en torno a la producción de alimentos para el autoconsumo en los hogares totonacos. La información se obtuvo mediante cuestionarios aplicados a una muestra probabilística en 77 viviendas. Los resultados revelan que el traspatio es utilizado para la obtención de alimentos vegetales y plantas medicinales, así como para la producción pecuaria con la crianza de aves y cerdos, destinados principalmente a la alimentación familiar. Además, se constituye como un espacio importante para la realización de celebraciones tradicionales, relacionadas con la cosmovisión de este grupo.

Abstract This paper analyzes the opinions of the residents of the studied communities on the possible development of mining in their region and existing perceptions on the subject. A descriptive cross-section study was conducted under a qualitative and quantitative variable methodology. Furthermore, primary sources were used with instruments such as surveys and interviews in order to obtain socioeconomic data of the families, their opinion and the perspective that the population has regarding gold mining exploitation and its possible impacts, the communities' fighting strategies, and the strategies designed by the mining companies. It was found that the majority of the communities of Santa María de Zotoltepec, Tuligtic, La Cañada, and Tetela de Ocampo Centro reject open-pit mining and their perception is negative in regard to the impacts that mining exploitation would have, in addition to feeling vulnerable with respect to the mining projects and the federal government.

Resumen Este trabajo tiene por objetivo analizar las opiniones de los habitantes de las comunidades de estudio acerca del posible desarrollo de la minería en su región y las percepciones sobre este tema. Para ello se elaboró un estudio descriptivo de corte transversal, bajo una metodología de variables cualitativas y cuantitativas; adicionalmente se emplearon fuentes primarias, con instrumentos como encuestas y entrevistas, para obtener datos socioeconómicos de las familias, las opiniones de estas y la perspectiva de la población frente a los proyectos de explotación minera de oro y sus posibles impactos, las estrategias de lucha de las comunidades y las estrategias diseñadas por las empresas mineras. Se encontró que la mayoría de la población en las comunidades de Santa María de Zotoltepec, Tuligtic, La Cañada y Tetela de Ocampo Centro rechaza la minería a cielo abierto y su percepción es negativa acerca de los impactos que tendría la explotación minera; además, se siente vulnerable frente a los proyectos mineros y al gobierno.

Abstract: Information on consumer acceptance of and preference for a product are vital to developing marketing strategies. An analysis was done of consumer acceptance of and preference for Queso Bola de Ocosingo, an artisanal cheese, aged for one of three periods: fresh, 21 d and 45 d. Sensory testing panels were organized at three food-related scenarios: a gourmet foods event; a rural culture fair; and a culinary exhibition. A total of ninety (90) panelists participated. Parametric and non-parametric statistical tests were applied to the data. Comparisons of panelist responses considering the scenarios and panelist socioeconomic characteristics found that panelists reporting lower income and educational levels more highly valued visual characteristics and preferred fresher cheeses. Panelists reporting higher income and educational levels appreciated cheese aroma and taste attributes influenced by aging period. Queso Bola de Ocosingo has production and cultural characteristics in common with other artisanal cheeses produced in Mexico, and promoting its consumption can contribute to preserving the country’s culinary heritage.

Resumen: El objetivo fue analizar la aceptación y preferencia del consumidor por el Queso Bola de Ocosingo con tres tiempos de maduración: fresco, 21 días y 45 días. Se realizaron 90 encuestas en tres escenarios relacionados con la gastronomía: Gourmet Show, Feria Nacional de la Cultura Rural en Chapingo y Muestra Gastronómica. La información se analizó a través de pruebas estadísticas paramétricas y no paramétricas. Al contrastar las respuestas, con los escenarios de evaluación y las características socioeconómicas de los panelistas, se encontró que aquellos que reportaron ingreso y nivel educativo más bajos, percibieron mejor las características visuales, prefiriendo los quesos más frescos; mientras que los panelistas con ingreso y nivel educativo más altos, apreciaron mejor los atributos asociados al aroma y el sabor del queso más maduro. El Queso Bola de Ocosingo comparte características productivas y culturales con otros quesos artesanales mexicanos, por lo que se espera contribuir para preservarlos como parte del patrimonio gastronómico del país.

RESUMO Objetivo Disfunção cognitiva é comum em pacientes com esclerose múltipla. Por isto, a Brief Repeatable Battery of Neuropsychological Tests (BRB–N) foi desenvolvida para avaliar as funções cognitivas mais frequentemente alteradas na doença. Entretanto, estão faltando dados normativos desta bateria no Brasil. Assim, nosso objetivo foi fornecer valores normativos contínuos e discretos da BRB–N para a população brasileira. Métodos Foram recrutados 285 indivíduos sadios da comunidade em 10 centros do Brasil e aplicada a versão A em 237 e a versão B em 48 sujeitos. Normas contínuas foram calculadas com análise de regressão múltipla. Resultados Escores brutos médios e 5°percentil para cada subteste são fornecidos, estratificados por idade e nível educacional. Os escores brutos dos sujeitos sadios foram convertidos em escores de escalas e postos em regressão quanto a idade, sexo e educação, fornecendo equações que podem ser usadas para calcular escores previsíveis. Conclusão Nossos dados normativos permitem um uso mais amplo da BRB–N na prática clínica e na pesquisa, fornecendo normas para dados discretos e contínuos. Normas para dados discretos deveriam ser usadas com cuidado e escores demograficamente ajustados são geralmente preferidos quando interpretando dados neuropsicológicos.

ABSTRACT Objective Cognitive dysfunction is common in multiple sclerosis. The Brief Repeatable Battery of Neuropsychological Tests (BRB–N) was developed to assess cognitive functions most–frequently impaired in multiple sclerosis. However, normative values are lacking in Brazil. Therefore, we aimed to provide continuous and discrete normative values for the BRB–N in a Brazilian population sample. Methods We recruited 285 healthy individuals from the community at 10 Brazilian sites and applied the BRB–N version A in 237 participants and version B in 48 participants. Continuous norms were calculated with multiple–regression analysis. Results Mean raw scores and the 5th percentile for each neuropsychological measure are provided, stratified by age and educational level. Healthy participants' raw scores were converted to scaled scores, which were regressed on age, sex and education, yielding equations that can be used to calculate predicted scores. Conclusion Our normative data allow a more widespread use of the BRB–N in clinical practice and research.

RESUMO Este artigo apresenta um caso clínico de fratura radicular horizontal, em paciente adulto, do sexo masculino, no terço apical, decorrente de prática esportiva, que, somado a outros fatores, levou à necrose pulpar. A Inicialmente, o paciente procurou atendimento de urgência, depois foi submetido a tratamento por endodontia, com utilização de hidróxido de cálcio entre as sessões. Inicialmente, o paciente procurou atendimento de urgência, e, posteriormente, recebeu tratamento por meio da endodontia, com utilização entre sessões de hidróxido de cálcio. Após um período de acompanhamento, foi realizada a obturação do conduto radicular e o elemento dental encontra-se clínica e radiograficamente estável passados dois anos do traumatismo. O acompanhamento deste caso será de longa duração, dividido em períodos de 12 meses por 10 anos, com avaliação clínica e radiográfica. A ocorrência de fratura dental em crianças e adolescentes de 10 a 14 anos é muito comum, principalmente durante prática esportiva e atividades de recreação. Pode-se esperar que jovens do sexo masculino tenham uma maior propensão a lesar seus dentes em comparação aos indivíduos do sexo feminino. O incisivo central superior é o dente mais comumente envolvido e, com frequência, após o trauma, evolui para necrose pulpar.

ABSTRACT This article presents a clinical case of horizontal root fracture, in an adult patient, male, in the apical third, due to the practice of sports, which, along with other factors, has led to pulp necrosis. Initially, the patient sought emergency care, and then he underwent treatment by endodontics, using calcium hydroxide between sessions. After a monitoring period, root canal obturation was performed and the tooth is clinically and radiographically stable 2 years after the trauma. In this case, monitoring is long-lasting, divided into 12-month periods for 10 years, with clinical and radiographic evaluation. Dental fracture in children and teenagers from 10 to 14 years is very common, especially during the practice of sports and recreation activities. It is expected that young male individuals have greater propensity to damage their teeth than young female individuals. Maxillary central incisor is the tooth most commonly involved, and it often evolves to pulp necrosis after trauma.

Os sintomas neuropsiquiátricos na doença de Alzheimer (DA) são prevalentes, porém suas relações com padrões de atrofia cortical não são totalmente compreendidas. Objetivos Comparar padrões de atrofia cortical entre DA e controles; verificar se há correlações entre sintomas neuropsiquiátricos e atrofia cortical. Método 33 pacientes com DA foram examinados pelo Inventário Neuropsiquiátrico. Os pacientes e 29 controles foram submetidos à RNM. Consideramos quatro síndromes: afetiva, apatia, hiperatividade e psicose. Correlações entre imagens estruturais e os scores foram feitas pelo Freesurfer. Os resultados foram significantes com um valor de p < 0,05, corrigido para múltiplas comparações. Resultados Pacientes exibiram atrofia nos córtices entorrinais, giros temporal médio e inferior esquerdos, e precuneo bilateralmente. Houve correlação entre síndrome afetiva e espessura cortical em estruturais frontais direitas, ínsula e polo temporal. Conclusão Medidas de espessura cortical revelaram atrofia na DA. Sintomas de depressão e ansiedade foram associados à atrofia dos córtices frontal direito, temporal e ínsula.

Neuropsychiatric symptoms in Alzheimer’s disease (AD) are prevalent, however their relationship with patterns of cortical atrophy is not fully known. Objectives To compare cortical atrophy’s patterns between AD patients and healthy controls; to verify correlations between neuropsychiatric syndromes and cortical atrophy. Method 33 AD patients were examined by Neuropsychiatric Inventory (NPI). Patients and 29 controls underwent a 3T MRI scanning. We considered four NPI syndromes: affective, apathy, hyperactivity and psychosis. Correlations between structural imaging and neuropsychiatric scores were performed by Freesurfer. Results were significant with a p-value < 0.05, corrected for multiple comparisons. Results Patients exhibited atrophy in entorhinal cortices, left inferior and middle temporal gyri, and precuneus bilaterally. There was correlation between affective syndrome and cortical thickness in right frontal structures, insula and temporal pole. Conclusion Cortical thickness measures revealed atrophy in mild AD. Depression and anxiety symptoms were associated with atrophy of right frontal, temporal and insular cortices.

Resumen Los estudios de muchos grupos faunísticos de invertebrados marinos han sido escasos en la zona de la Región Autónoma del Atlántico Sur (RAAS), de Nicaragua. A lo anterior se añade la falta de información general con respecto a la biodiversidad faunística de Corn Island. La fauna de equinodermos estudiada en este trabajo proviene de una gran variedad de ambientes, desde la zona rocosa litoral, arenales, pastos marinos hasta zonas de arrecife coralino. Los equinodermos recolectados, se obtuvieron a partir de 14 puntos de muestreos elegidos a partir del conocimiento de los pescadores locales; en diversos tipos de sustratos marinos, auxiliados por equipo de buceo SCUBA durante el periodo comprendido entre agosto 2012 y marzo 2013. Se registró un total de 41 especies correspondientes a cuatro clases: tres especies de asteroideos, 16 especies de ofiuroideos, 11 especies de equinoideos y 11 especies de holoturoideos. La especie más común fue Ophiolepis impressa estuvo presente en diez de las 14 localidades, seguida de Diadema antillarum, Eucidaris tribuloides y Ophioderma cinerea que estuvieron presentes en siete localidades cada una. Las especies menos comunes fueron Clypeaster rosaceus, Leodia sexiesperforata, Meoma ventricosa y Ophioderma guttata. El estudio de las comunidades de estos invertebrados en diversos hábitats marinos, facilita la comparación del estado de fluctuación de dichas comunidades a lo largo del tiempo, ya fuesen cambios naturales o causados por las actividades humanas.

Abstract There are few works on ecology and diversity of echinoderms in Nicaragua. Studies of many faunal groups of marine invertebrates, in particular which should focus on the fauna of tropical areas, have been scarce or have received only limited attention from the scientific community and government authorities of the South Atlantic Autonomous Region (RAAS) of Nicaragua. Scientific research on these groups has targeted mainly resources of commercial importance (e.g. spiny lobster, Panulirus argus). There is lack of information regarding the faunal biodiversity of Corn Island in general. The echinoderm fauna studied in this work comes from a wide variety of environments, from the rocky coastal area, sandy beaches, sea grass to areas of coral reef. Echinoderms were collected, from 14 points in a variety of marine substrates, aided by SCUBA diving equipment during the period from August 2012 to March 2013. There was a total of 41 species corresponding to four classes: three species of Asteroids, 16 species of ophiuroids, 11 species of Echinoids and 11 species of holoturoids. The most common species was Ophiolepis impressa present in ten of the 14 localities, followed of Diadema antillarum, Eucidaris tribuloides and Ophioderma cinerea who were present at seven locations each, respectively. The less common species were Clypeaster rosaceus, Leodia sexiesperforata, Meoma ventricosa and Ophioderma guttata. The study of echinoderms in diverse marine habitats facilitates the comparison of the state of fluctuation of those communities along time. Whether they were natural or caused by human activities. Therefore, the present study expands knowledge about the species of echinoderms that live in shallow areas of Corn Island (between 0-10 m depth), so able to establish measures for the conservation of these species.

Introduction: Surgery of the thyroid gland is the most performed procedure by the endocrine surgeon. In the last years, new techniques have been incorporated in this procedure. Our objective is to analyse the impact of these techniques in our department. Methods: We performed a retrospective and comparative study among three samples of patients submitted for total thyroidectomy. Group I: Sample of 96 patients operated between 2004 and 2007 performing total thyroidectomy. In this period we didn't use ultrasonic scalpel (US) nor intraoperative neuromonitoring (INM). Group II: Sample of 108 patients operated between 2008 and 2010. In this group we used US for hemostasis. Group III: Sample of 82 patients operated between 2011 and 2012. In this group we used both US and INM. The groups are compared: complications, postoperative stay, surgical time and costs per patient. Results: We analysed the following complications: haemorrhage, postoperative hipocalcemia and recurrent nerve palsy. We didn't find significant differences among the samples of patients but there were a less percentage of recurrent palsy in the third group (4.9% vs 12.5 and 11.1%). We found significant differences when stay, surgical time and costs were analysed. Conclusion: The use of new techniques in thyroid surgery has supposed an improvement not only in the clinic outcomes but in the surgical time.

Objetivo: La cirugía de la glándula tiroides representa el procedimiento más frecuente que realiza el cirujano endocrino. En los últimos años se han ido incorporando nuevas técnicas aplicadas a este procedimiento. El objetivo de nuestro trabajo es analizar el impacto que dichas técnicas han tenido en nuestro servicio. Material y Métodos: Estudio retrospectivo y comparativo entre tres muestras de pacientes a los que se realizó tiroidectomía total. Grupo I: Muestra de 96 pacientes intervenidos entre 2004 y 2007 a los que se realizó tiroidectomía total. En este período no se utilizó bisturí ultrasónico (BU) ni neuromonitorización intraoperatoria (NMI). Grupo II: Muestra de 108 pacientes intervenidos entre 2008 y 2010. En este grupo se realizó hemostasia con BU. Grupo III: Muestra de 82 pacientes intervenidos entre 2011 y 2012. Se utilizó tanto el BU como la NMI. Se comparan los grupos en cuanto a: complicaciones, estancia postoperatoria, tiempo quirúrgico y coste por paciente. Resultados: Las complicaciones analizadas fueron: hemorragia, hipocalcemia postoperatoria y parálisis del nervio laríngeo recurrente. No encontramos diferencias significativas entre los grupos aunque sí hay una menor tasa de parálisis recurrenciales en el tercer período (4,9% vs 12,5 y 11,1%). Hemos obtenido diferencias significativas en estancia, tiempo quirúrgico y coste por paciente. Conclusión: La inclusión de las nuevas técnicas en cirugía tiroidea ha supuesto una mejora en los resultados clínicos así como un ahorro de tiempo de quirófano.

Objetivo Avaliar se o mês de nascimento em diferentes latitudes da América do Sul pode influenciar a presença ou gravidade da esclerose múltipla (EM) na vida. Método Neurologistas de quatro países da América do Sul trabalhando em unidades de EM coletaram os dados de seus pacientes com referência ao mês de nascimento, gênero, idade e progressão da doença. Resultados A análise dos dados mostrou que, para 1207 pacientes com EM e 1207 controles, não havia diferença significativa no mês de nascimento com relação à prevalência de EM em quatro zonas de latitude (0–10; 11–20; 21–30; e 31–40 graus). Não houve relação entre o mês de nascimento e a gravidade da doença em nenhuma destas zonas. Conclusão Os resultados deste estudo mostram que pacientes com EM nascidos de mães grávidas em diferentes latitudes sul não seguem o padrão dos resultados sazonais encontrados nas latitudes norte.

Objective To assess whether the month of birth in different latitudes of South America might influence the presence or severity of multiple sclerosis (MS) later in life. Methods Neurologists in four South American countries working at MS units collected data on their patients' month of birth, gender, age, and disease progression. Results Analysis of data from 1207 MS patients and 1207 control subjects did not show any significant variation in the month of birth regarding the prevalence of MS in four latitude bands (0–10; 11–20; 21–30; and 31–40 degrees). There was no relationship between the month of birth and the severity of disease in each latitude band. Conclusion The results from this study show that MS patients born to mothers who were pregnant at different Southern latitudes do not follow the seasonal pattern observed at high Northern latitudes.

ObjetivoFoi analisar o campo visual (CV) de um grupo de pacientes com esclerose múltipla (EM) na fase remissiva e a presença de lesões nas imagens de ressonância magnética (MRI) na radiação óptica.MétodoO CV foi estudado em 60 participantes (faixa etária de 20-51 anos): 35 pacientes EM remitente-recorrente: [20 neurite óptica (+), 15 neurite óptica (-)] e 25 controles. Foram obtidas MRI (3-Tesla) de todos os pacientes.ResultadosHavia alterações visuais nos pacientes com EM quando comparados aos controles. A maioria apresentava defeitos difusos de CV. Todos os pacientes, à exceção de um, apresentaram lesões nas vias visuais posteriores. Não foi observada diferença significativa quanto a número, extensão e distribuição das lesões entre os pacientes com e sem história de neurite óptica. Um paciente apresentou hemianopsia homônima.ConclusãoAnormalidades nas via visuais posteriores foram encontradas na maior parte dos pacientes com EM independentemente da história de neurite óptica.

ObjectiveIt was to investigate visual field (VF) abnormalities in a group of multiple sclerosis (MS) patients in the remission phase and the presence of magnetic resonance imaging (MRI) lesions in the optic radiations.MethodsVF was assessed in 60 participants (age range 20-51 years): 35 relapsing-remitting MS patients [20 optic neuritis (+), 15 optic neuritis (-)] and 25 controls. MRI (3-Tesla) was obtained in all patients.ResultsVisual parameters were abnormal in MS patients as compared to controls. The majority of VF defects were diffuse. All patients except one had posterior visual pathways lesions. No significant difference in lesion number, length and distribution was noted between patients with and without history of optic neuritis. One patient presented homonymous hemianopsia.ConclusionPosterior visual pathway abnormalities were found in most MS patients despite history of previous optic neuritis.
