RESUMO

BACKGROUND: Caries is a worldwide distributed oral disease of multifactorial nature, with Streptococcus mutans being the most commonly isolated bacterial agent. The glycosyltransferases of this bacterium would play an essential role in the aetiology and pathogenesis of caries. AIM: We explored how the glucosyltransferase-B (gtf-B) gene variability of S. mutans from children in central Argentina correlated with their caries experience and how these strains were genetically related to those of other countries. DESIGN: Dental examinations were performed on 59 children; dmft and DMFT indexes were calculated. From stimulated saliva, S. mutans was grown and counted (CFU/mL). From bacterial DNA, the gtf-B gene was amplified and sequenced. Alleles were identified and their genealogical relationships established. Clinical, microbiological, and genetic variables were correlated with caries experience. Our sequences were included in a matrix with those from 16 countries (n = 358); genealogical relationships among alleles were obtained. Population genetic analyses were performed for countries with >20 sequences. RESULTS: The mean dmft + DMFT was 6.45. Twenty-two gtf-B alleles were identified here, which showed low genetic differentiation in the network. Caries experience was correlated with CFU/mL, but not with allele variation. Low differentiation was found among the 70 alleles recovered from the 358 sequences and among the countries analyzed. CONCLUSION: In this study, caries experience in children was correlated with the number of CFU/mL of S. mutans but not with the gtf-B gene variability. Combined genetic analyses of worldwide strains support the theory that this bacterium experienced population expansions, probably associated with agriculture development and/or food industrialization.

RESUMO

Patients with critical illness develop physiological dysfunction which provokes multi-organ system failure and triggers fatal outcomes and irreversible injuries or even death. Inside Internal Medicine services of Mexican hospitals, especially in public hospitals, there is a considerable number of critically ill patients with multiple pathologies who require surveillance to reach clinical goals of their treatment. We present a summary of guidelines and goals of the most prevalent critical diseases inside Internal Medicine services, which are necessary to guide treatments.

RESUMO

Introducción: El síndrome de Marcus-Gunn se manifiesta con retracción o elevación del párpado ptótico ante la estimulación del músculo pterigoideo del mismo lado y el término "guiño mandibular" es inapropiado ya que el párpado no siempre desciende. Puede producirse en la apertura bucal, masticación, avance mandibular, al sonreír, silbar, bruxar, sacar la lengua, deglutir, chupar, cantar, en la contracción esternocleidomastoidea, maniobra de Valsalva, respirar o inhalar. Es congénito y de modalidad rara y autosómica dominante. Objetivo: Contribuir al conocimiento de esta rara enfermedad y a su relación con el ámbito odontológico. Presentación del caso: Se trata de un niño de 3 años diagnosticado de síndrome de Marcus-Gunn en el periodo neonatal, por la observación de la madre de una apertura palpebral izquierda durante la succión nutritiva. No presenta otras enfermedades ni antecedentes de interés. En la exploración extraoral se advierte una ptosis palpebral derecha y apertura palpebral izquierda en los movimientos mandibulares y deglución. La intensidad del reflejo se incrementa en estados de ansiedad derivados del tratamiento dental. Conclusiones: el síndrome de Marcus-Gunn es una entidad rara en pediatría, en la cual sus hallazgos clínicos determinan el diagnóstico. Teniendo en cuenta que en ocasiones presentan alteraciones oculares, nada nos hace sospechar la presencia de una enfermedad oral específica(AU)


Introduction: Marcus Gunn syndrome manifests with retraction or elevation of the eyelid ptotico while stimulation of the pterygoid muscle on the same side and the term jaw-winking is inappropriate because the eyelid does not always goes down. It can occur during mouth opening, mastication, mandibular advancement, while smiling, whistling, bruxing, sticking out the tongue, swallowing, sucking, singing, during the sternocleidomastoid contraction, the Valsalva maneuver, breathing or inhaling. This syndrome is congenital and rare, and of autosomal dominant modality. Objective: To contribute to the knowledge of this rare disease and its relationship with the odontologic field. Presentation of the case: 3 years old boy diagnosed with Marcus Gunn syndrome in the neonatal period by the observation of the mother of a left palpebral opening during the nutritive sucking. He does not present other diseases or a background of interest. In the extraoral exploration, it is noticed a right palpebral ptosis and a left palpebral opening in the jaw movements and in swallowing. The intensity of the reflex increases in anxiety states arising from the dental treatment. Conclusions: Marcus Gunn syndrome is a rare entity in pediatrics, in which its clinical findings determine the diagnosis. Taking into account that sometimes it presents ocular alterations, nothing makes us suspect the presence of a specific oral disease(AU)

RESUMO

La estatificación axilar es uno de los más importantes factores pronósticos en pacientes con cáncer de mama. La punción con aguja fina (PAAF) guiada por ecografía de los ganglios axilares es un método técnicamente factible y de baja morbilidad para la evaluación preoperatoria del compromiso axilar, en especial cuando hay sospecha clínica o ecográfica de compromiso a ese nivel. Este procedimiento aún no es parte de la rutina en la práctica general y sus indicaciones no se han establecido claramente. Objetivos: Analizar la utilidad de la punción con aguja fina (PAAF) guiada por ecografía de los ganglios linfáticos axilares en la evaluación preoperatoria de las pacientes con cáncer de mama y sospecha de compromiso axilar clínico o por imágenes; determinar la sensibilidad y especificidad del método;comparar los resultados con la bibliografía. Material y método: Se llevó a cabo un estudio observacional, prospectivo donde se evaluaron 23 pacientes con cáncer de mama a las cuales se les realizó PAAF axilar en el Servicio de Ginecología y el Servicio de Diagnóstico por Imágenes del Hospital Interzonal General de Agudos (HIGA) de Mar del Plata, en el períodonoviembre de 2013 a agosto de 2014. Resultados: La edad promedio de las pacientes fue de 49,4 años. El tamaño tumoral promedio por imágenes fue de 31 mm y por anatomía patológica de 32,5 mm. Se realizaron 25 punciones axilares (dos casos bilaterales) con 14 resultados positivos (56%), 9 negativos (36%) y 2 (8%) insatisfactorios. La sensibilidad del método fue del 82,3% con un 17,7% de falsos negativos; la especificidad fue del 100%, el VPP del 100% y el VPN del 66,6%. No hubo diferencia significativa en la relación del tamaño tumoral con el resultado de la PAAF...

RESUMO

Este articulo describe una experiencia de investigación y extensión entre dos unidades académicas de la Universidad Nacional de La Plata: un proyecto gratuito de educación de adultos mayores en Barrios por fuera del casco urbano de la ciudad de La Plata (perteneciente a la Facultad de Humanidades y Ciencias de la Educación) y una cátedra de etnografía, que aborda la variabilidad sociocultural, incluidas organizaciones y conceptualizaciones sobre la edad (correspondiente a la Facultad de Ciencias Naturales y Museo). Partiendo de la importancia de que los estudiantes universitarios se inicien en las prácticas profesionales, se propuso realizar una experiencia conjunta en la cual interactuasen adultos mayores y jóvenes. Entre sus objetivos consideramos: fomentar los vínculos entre Universidad y comunidad; sensibilizar, explorar y producir reflexiones sobre Etnografía y AM; caracterizar etnográficamente y describir a los adultos mayores del Programa Pepam en los Barrios. Dado el interés exploratorio, se emplearon las técnicas de la encuesta y la observación. Los estudiantes procesaron los datos recogidos en su trabajo de campo, los cuales fueron examinados a la luz de material bibliográfico analizado para el caso de otras sociedades en torno al envejecimiento y los compartieron con la comunidad estudiada y con interesados (docentes – directivos- familiares). La experiencia contribuyó a la formación de losfuturos egresados y produjo conocimiento significativo sobre los AM, su participación en el programa y otros aspectos de su vida. Además generó un espacio de diálogo entre la universidad y un sector cada vez más significativo en la demanda de exploración, y generación de políticas y respuestas a su particular situación.


This paper describes a research and extension experience between two academic units of the National University of La Plata: Free education project for seniors in neighborhoods outside the urban area of the city of La Plata (belonging to the Faculty of Humanities and Educational Sciences) and a chair of ethnography, which addresses cultural variability, including organizations and conceptualizations of age (corresponding to the Faculty of Natural Sciences and Museum). Based on the importance of college students start in professional practices, was proposed a joint experience in which older and younger adults interactuasen. Among its objectives consider: foster links between university and community awareness, explore and produce reflections on ethnography and AM; characterize and describe ethnographically seniors PEPAM Program in Barrios. Given the exploratory interest, we used survey techniques and observation. Students processed data collected in fieldwork, which were examined in the light of bibliographic material analyzed for the case of other companies around the aging and shared with the community studied and stakeholders (teachers - family - managers).The experience contributed to the training of future graduates and produced significant knowledge about the AM, their participation in the program and other aspects of your life. Also created a space for dialogue between the university and an increasingly more significant in the demand for exploration, and development of policies and answers to their particular situation.

RESUMO

Processes of spatial mobility among the Mbya are of interest in anthropological and ethnobiological studies, as these processes are related to transformations in the landscape and the environment. Despite this, ethnographic literature usually focuses itself on the mobility of Guaraní communities from the perspective of population dynamics on a regional scale. Our research among two Mbya-Guaraní communities in the Argentinean province of Misiones has enabled us to recognize patterns of mobility on a micro-scale. Certainly, the mobility of adult members of these communities as they perform hunting and gathering activities delimit spaces of individual use. We consider the different pathways as "signatures in landscape", resulting from processes of spatial mobility inherent to those activities. Taking into account the gathering and circulation of medicinal plants for treatment of gastrointestinal illnesses, we have been able to identify different pathways inherent in their search, towards the monte or other spaces away from de settlement. The design and construction of the pathways is determined by the specific personal knowledge of individuals who search for these valuable resources. Using both strategies of direct observation--as members of the community manipulate different resources during these search and gathering trips--and interviews, we have been able to gather and interpret significant information on the strategies used by the Mbya to domesticate the monte areas. As a consequence of our approach we suggest that the landscape design resulting from these trips should not be considered a consensual or collective strategy of the whole community; it is rather the result of the daily strategies of individuals, which involves the selection of resources mainly based on each individual's knowledge and interests.

RESUMO

The aim of this work is to analyze and discuss the phytotherapy employed for two kinds of diseases, osteo-articular and cardio-circulatory, among the inhabitants of Molinos (Calchaquí Valley, Salta Province, Northwestern Argentina). These diseases take their origin in certain environmental conditions as well as the rural activities characteristic of the zone. The observations and interviews conducted among "medicos campesinos" (traditional healers) and the general population provided valuable information concerning the relationship between man and his environment, as it relates to health-illness processes. As a result of our research, we present a chart of the 25 recorded diseases and the 42 plant species employed in their therapy, considering the organs used, the ways of preparation and administration, as well as the geographic origin.
