Seguimiento multidisciplinario en el control del penfigoide de membranas mucosas

The term Mucous Membrane Pemphigoid includes a group of chronic and autoimmune vesiculobullous diseases involving mainly the mucosa. The aim of present paper is to describe two clinical cases of Mucous Membrane Pemphigoid with gingival involvement to arrive to a proper diagnosis of the lesion and also to discuss the therapeutic behavior. Different complementary examinations were conducted including Nikolsky test, incisional biopsy, the LE cells study and of antinuclear antibodies, as well as the evaluation of dermatologists and ophthalmologists. It was necessary the replacement of toothpastes, the nutritional and psychological guiding, the hygiene care and the use of topic corticoids. There were periods of remission and exacerbation of clinical picture during follow-up being necessary the therapeutics fitting and the oral hygiene care reinforcement. It is important the multidisciplinary interaction in the care of these cases for treatment and follow-up control, as well as to reinforce all orientations and cares related to oral hygiene and the caution in the use of corticoids.

¿Inestabilidad o estabilidad en la política brasileña? Partidos políticos y presidente de la República contra la incertidumbre

This article examines what political scientists think of the Brazilian political system, especially in regard to the relationship between the executive and legislative branches. There are two opposing camps of scholars who focus on how political parties behave in the Chamber of Deputies. While the first defends a political system that produces undisciplined representatives, the second supports a legislative organization that produces disciplined politicians.

Validez y confiabilidad de la versión en español de la escala multidimensional de la UNESP-Botucatu para evaluar el dolor postoperatorio en gatos

This study focused on the validation of the Spanish version of the UNESP-Botucatu multidimensional composite pain scale to assess postoperative pain in cats. The original scale in Portuguese was translated into Spanish by two independent translators, and summarised in one version by a third individual. The summarised version was back-translated and minor adjustments were made. The scale was reviewed by three anesthesiologists with Spanish as their first language, and the final version was submitted to psychometric testing. Thirty cats undergoing ovariohysterectomy were video recorded during the perioperative period. Six observers from different spanish speaking countries, who had Spanish as the first language watched the videos and determined the pain scores using the Spanish version of the scale, identifying the cats that should receive analgesics. Videos were reanalysed in a different order about 2 months after the first assessment. The sensitivity to change, content and construct validity were established by the significant change in pain scores in response to surgery and analgesics. The agreement between the evaluations of the 'gold standard'(researcher that developed the scale) and the other observers confirmed the criterion validity. Inter- and intra-rater reliability, evaluated by intra-class correlation coefficient, ranged from good to very good for all scale items. The cut-off point for rescue analgesia identified by Receiver Operating Characteristic curve was > 7 with 92% of sensitivity and 91% of specificity. The Spanish version of the UNESP-Botucatu multidimensional composite pain scale is interpretable (has an optimal analgesic intervention score), valid and reliable instrument for assessing acute pain in cats undergoing ovariohysterectomy.

Absentismo laboral por patología odontológica y médica en una industria de gran porte del sector mecánico y mueblero

Introduction: The current Brazilian legislation states that health services must be performed by the Specialized Service of Safety Engineering and Labor Medicine (SESMT). Objective: To analyze the dental and medical reasons for absenteeism, checking the interference of factors such as age, gender and position of the worker, and most of the reasons that led the employee to miss work. Material and methods: The research appears as a descriptive study with a quantitative approach. The dental and medical certificates and statements of attendance were analyzed, duly approved, lodged in a acrylic industry in the city of Araçatuba-SP, from January to July 2011. Results: Of the total number of certificates (n = 1841), only 103 (5.6%) were for dental reasons. Predominance of the age group of 20-29 years, males and with non-administrative function. The reasons most dental and medical certificates stated that led the workers to miss working days were "inclusive and impacted teeth" and "diarrhea and gastroenteritis of presumed infectious origin", respectively. As to factors related to absenteeism, there was a severity index of 2.83, 1.33 frequency and average duration of absences of 2.12. Conclusions: It is concluded that dental reasons had little weight on total absences due to illness that caused the temporary leave of the worker for a shorter period. The age and function variables influence the occurrence of work absenteeism.

Producción de tomate tipo italiano en función del volumen de la celda y de la edad de las mudas

Con el objetivo de evaluar la influencia de las bandejas de celdas sobre la producción de tomate tipo italiano en el campo, se realizó este trabajo en Piracicaba, SP, Brasil, de mayo a agosto del 2005. Los tratamientos consistieron en cuatro volúmenes de recipiente, tres bandejas de poliestireno expandido de 121,2; 34,6 y 12,0 cm³ y de una bandeja de plástico rígido de 14,0 cm³ (72, 128, 288 y 450 celdas, respectivamente) combinadas con cuatro edades para el trasplante (19, 24, 29 y 34 días después de la siembra). El delineamiento para la producción de mudas fue completamente al azar, con cinco plantas por parcela y tres repeticiones. Se analizaron área foliar, altura, masa verde y seca de la parte aérea y raíz y la calidad de las mudas. En la producción a campo, el delineamiento fue en bloques al azar con diez plantas por parcela y tres repeticiones. Fueron evaluadas la precocidad para inicio de cosecha, producción comercial y total por planta. Volúmenes mayores de recipiente (121,2 y 34,6 cm³) presentaron mejor calidad de mudas. En la producción de frutos, el número comercial y total de frutos por planta fue superior en la muda de 24 días de edad, sin embargo, en la producción total de frutos, no hubo diferencia entre los tratamientos. Por otro lado, también se obtuvo precocidad para la cosecha en los tratamientos realizados en los volúmenes de 121,2 y 34,6 cm³. El volumen de recipiente de 14,0 cm³ (450 celdas) resultó en mudas de calidad muy inferior, alongadas y raquíticas.

Comparative analysis of the corps en cerise in several species of Laurencia (Ceramiales, Rhodophyta) from the Atlantic Ocean

Different species of Laurencia have proven to be a rich source of natural products yielding interesting bioactive halogenated secondary metabolites, such as terpenoids and acetogenins. It is shown that such compounds are accumulated in the spherical, reniform to claviform refractive inclusions called corps en cerise (CC), which are intensively osmiophilic and located mainly in the cortical cells of the thalli and also in trichoblast cells. Up to now, it was believed that CC were present only in these two kinds of cells. Recently, however, a species of Laurencia, L. marilzae, with CC in all cells of the thallus, i.e., cortical, medullary, including the pericentral and axial cells, as well as in the trichoblasts, was described from the Canary Islands, and subsequently also reported to Brazil and Mexico. Within the Laurencia complex, only Laurencia species produce CC. Since the species of Laurencia are targets of interest for the prospection of bioactive substances due to their potential antibacterial, antifungal, anticholinesterasic, antileishmanial, cytotoxic, and antioxidant activities, the present paper carries out a comparative analysis of the corps en cerise in several species of Laurencia from the Atlantic Ocean to obtain basic information that can support natural product bioprospection projects. Our results show that the number and size of the CC are constant within a species, independent of the geographical distribution, corroborating their use for taxonomical purposes to differentiate groups of species that present a lower number from those that have a higher number. In this regard, there was a tendency for the number of CC to be higher in some species of Laurencia from the Canary Islands. The presence of CC can also be used to distinguish species in which these organelles are present in all cells of the thallus from those in which CC are restricted to the cortical cells. Among the species analyzed, L. viridis displayed the most varied secondary metabolites composition, such as sesquiterpenes, diterpenes, triterpenes, all of which showed potent antiviral, cytotoxic, and antitumoral activities, including protein phosphatase type 2A (PP2A) inhibitory effects.

La regulación de los servicios de electricidad en Argentina y Brasil (1890-1962)

El artículo analiza la evolución de la regulación del sector eléctrico en Argentina y Brasil entre 1890 y 1960. Desde la instalación de las primeras usinas eléctricas a fines del siglo diecinueve hasta los años treinta, el control de las empresas concesionarias estuvo a cargo de las autoridades municipales en ambos países. No obstante, la similar estructura de los sistemas eléctricos en Argentina y en Brasil, la participación del estado en la regulación de este sector estratégico para el desarrollo económico, se produjo en diferentes coyunturas. Como resultado de la crisis de 1930, el gobierno brasileño transformó los principios jurídicos que reglamentaban la gestión de la electricidad aplicando un criterio de regulación discrecional; mientras que el estado argentino intervino una década más tarde, nacionalizando las empresas. Mediante la comparación de las trayectorias regulatorias en ambos países, se identifican las divergencias en las políticas eléctricas y su impacto en los sistemas eléctricos en los años de la segunda posguerra.

Evolução temporal da proliferação neointimal após implante de dois tipos de stent farmacológico com polímeros biodegradáveis em modelo porcino: avaliação qualitativa por tomografia de coerência óptica sequencial

INTRODUÇÃO: Baseados na hipótese de que a neoíntima encontrada em stents farmacológicos (SFs) com polímeros biodegradáveis aos 28 dias não é a neoíntima definitiva e de que a tomografia de coerência óptica (TCO) é um método eficaz para a avaliação sequencial da neoíntima, objetivamos, neste estudo experimental, comparar os achados da TCO aos 28 dias e aos 90 dias em dois tipos de SF com polímeros biodegradáveis: o stent liberador de sirolimus (Inspiron®, Scitech) e o stent liberador de biolimus A9 (Biomatrix®, Biosensors International). MÉTODOS: No total, 6 porcos não-ateroscleróticos foram submetidos a implante de 6 stents Inspiron® e de 6 stents Biomatrix®. Cada porco recebeu os dois tipos de stent, um em cada artéria coronária (descendente anterior e circunflexa) e após 28 dias e 90 dias foram realizadas avaliações qualitativas intrastent a cada milímetro com TCO. RESULTADOS: A avaliação qualitativa, feita por pareamento milímetro a milímetro intrastent, evidenciou neoíntima heterogênea em 39% aos 28 dias e em 0% aos 90 dias, presença de tecido intraluminal em 18% aos 28 dias e em 0% aos 90 dias, irregularidade luminal em 62% aos 28 dias e em 2% aos 90 dias (P < 0,005). Não houve diferença entre os grupos quanto à qualidade da neoíntima ao longo do tempo (P > 0,05). CONCLUSÕES: Os achados à TCO corroboram a hipótese de que a neoíntima encontrada em SFs com polímeros biodegradáveis aos 28 dias não é a neoíntima definitiva. A evidência experimental mais significativa é a mudança das características da neoíntima observada à TCO sequencial.

Improvements in the experimentation and the representation of thermodynamic properties (iso-p VLE and y) of alkyl propanoate+alkane binaries

[EN]This paper presents the experimental measurements of isobaric vapor−liquid equilibria (iso-p VLE) and excess volumes (vE) at several temperatures in the interval (288.15 to 328.15) K for six binary systems composed of two alkyl (methyl, ethyl) propanoates and three odd carbon alkanes (C5 to C9). The mixing processes were expansive, vE > 0, with (δvE/δT)p > 0, and endothermic. The installation used to measure the iso-p VLE was improved by controlling three of the variables involved in the experimentation with a PC.

The uncertainty in standardised sound power measurements: complying with ISO 17025

In the context of “testing laboratory” one of the most important aspect to deal with is the measurement result. Whenever decisions are based on measurement results, it is important to have some indication of the quality of the results. In every area concerning with noise measurement many standards are available but without an expression of uncertainty, it is impossible to judge whether two results are in compliance or not. ISO/IEC 17025 is an international standard related with the competence of calibration and testing laboratories. It contains the requirements that testing and calibration laboratories have to meet if they wish to demonstrate that they operate to a quality system, are technically competent and are able to generate technically valid results. ISO/IEC 17025 deals specifically with the requirements for the competence of laboratories performing testing and calibration and for the reporting of the results, which may or may not contain opinions and interpretations of the results. The standard requires appropriate methods of analysis to be used for estimating uncertainty of measurement. In this point of view, for a testing laboratory performing sound power measurement according to specific ISO standards and European Directives, the measurement of uncertainties is the most important factor to deal with. Sound power level measurement, according to ISO 3744:1994 , performed with a limited number of microphones distributed over a surface enveloping a source is affected by a certain systematic error and a related standard deviation. Making a comparison of measurement carried out with different microphone arrays is difficult because results are affected by systematic errors and standard deviation that are peculiarities of the number of microphones disposed on the surface, their spatial position and the complexity of the sound field. A statistical approach could give an overview of the difference between sound power level evaluated with different microphone arrays and an evaluation of errors that afflict this kind of measurement. Despite the classical approach that tend to follow the ISO GUM this thesis present a different point of view of the problem related to the comparison of result obtained from different microphone arrays.
