O Serviço Social e a exclusão/inclusão social dos portadores de HIV/AIDS :demandas e desafios nos hospitais públicos

This research presents the labors developed by the Social Service unto socially excluded HIV/Aids positives at public hospitals in Rio Grande do Norte (RN). It purposes to identify and to analyze the demands brought by the holder onto the Social Service professional as well as the challenges the latter face to minister to the former. It privileges, from the methodological viewpoint, the qualitative and quantitative analysis with the application of questionnaires, direct observation, semi-structured interviews and bibliographic references. Data were collected from 12 (twelve) social assistants who work at Giselda Trigueiro Hospital in Natal (7) and Rafael Fernandes Hospital in Mossoró (5). The central hypothesis that guided this study is that the social inclusion/exclusion process experienced by the HIV/Aids positive on society implies a demand for the Social Service that is inserted in the public health context (specially in HIV-referred public hospitals), whose agents, however, when attempting to answer those demands, meet obstacles due to both the precariousness of public health services and the social complexity that concerns the HIV/Aids epidemic. Results point out that, de facto, the HIV/Aids epidemic, because of the social exclusion/inclusion process to which the holder is subject results a demand for the social agents at hospitals. Demands rise principally from the patient s life condition, considering the increasing pauperization in the epidemic context. As to what it is concerned, social assistants, responding to the needs, come across concrete twofold challenges: the illness in itself, for all social, negative aspects that make part of quotidian life of holders; and the precarious state of the public health service in RN State, since that working conditions are unsatisfactory

O Processo de revisão do benefício de prestação continuada-BPC: uma lógica de exclusão ou inclusão social

This research comprises a study about the social assessment performed by the Social Worker in the review process of the Benefit of Continued Installment. The Benefit of Continued Installment was implemented in 1996 and guarantees a minimum salary to the deficiency person and to an elder with sixty five years or more and that proves not to have ways to support neither himself/herself nor his/her own family. It is a demand to include in the BPC that the maximum income of a family does not exceed ¼ of minimum salary and that every two years this benefit to be revised to evaluate its continuity based in its original conditions. This study was carried out in the municipality of Natal/RN, with thirteen social workers, being the collection of data performed through interviews and social assessments of the users that count with the benefit. The results show that the users selected by the criterion of the income, present a profile of poverty and deprivations demonstrated through several situations survived in its daily life, indicative of vulnerability. It was demonstrated that the Social workers has relative autonomy in the evaluations along with the users and that it denotes the necessity of inclusion. However, by following the imposed criteria, it corroborates with the logic of exclusion. So, it is identified in the Municipality of Natal/RN, following the orientation given the politics of social work at national level, the implementation of revision of the BPC, for the social workers, from rigorous processes of selection and exclusions

As diretrizes da política pública de saúde bucal e suas inflexões nos serviços da Clínica Odontológica da UFRN

The crisis that the Brazilian State have been crossing throughout the last decades has revealed intense oscillations in the the way of life of the population reality. In the health area, specifically of buccal health, new alternatives of attending to demands for odontological services have been increasing from the 1990 decade. The research had as objective to analyze the demand of the services of the clinic-school of odontology of the UFRN to identify the socio-economic profile of the users and the inflections of the standards of the National Politics of Buccal Health. The methodology is based on a dialectic perspective and a quali-quantitative boarding. It was used as instrument of data collection forms with open and closed questions, applied to two distinguished groups of citizens: 53 users of the services and 12 pupils of 9th and 10th term of the Odontology Course. The results reaffirm that, with the aggravation of the crisis of SUS (Sistema Único de Saúde- Single Health System) grow the difficulties of accessing the odontological services of the users majority. The subjects of the research make use of a regular socio-economic condition, with high school, own house, formal bond to labor and monthly medium income between 1 and 2 minimum wages. The conclusive analyses point to the selective and exculpatory character of the buccal health right, mainly, those users who find themselves in situation of extreme poverty and social vulnerability. Immediate and of lesser cost odontological assistance is what it s aimed, but the standards praised in the Public Politics of Buccal Health walk in another direction, requiring a bigger strongness of the formation bases and implementation of the programmatical actions since the academic field until the effectiveness of Politics of Buccal Health as a right while as a right to attention and care

Nasalance and nasality at experimental velopharyngeal openings in palatal prosthesis: a case study

The use of prosthetic devices for correction of velopharyngeal insufficiency (VPI) is an alternative treatment for patients with conditions that preclude surgery and for those individuals with a hypofunctional velopharynx (HV) with a poor prognosis for the surgical repair of VPI. Understanding the role and measuring the outcome of prosthetic treatment of velopharyngeal dysfunction requires the use of tools that allow for documenting pre- and post-treatment outcomes. Experimental openings in speech bulbs have been used for simulating VPI in studies documenting changes in aerodynamic, acoustic and kinematics aspects of speech associated with the use of palatal prosthetic devices. The use of nasometry to document changes in speech associated with experimental openings in speech bulbs, however, has not been described in the literature. Objective: This single-subject study investigated nasalance and nasality at the presence of experimental openings drilled through the speech bulb of a patient with HV. Material and Methods: Nasometric recordings of the word "pato" were obtained under 4 velopharyngeal conditions: no-opening (control condition), no speech bulb, speech bulb with a 20 mm(2) opening, and speech bulb with 30 mm(2) opening. Five speech-language pathologists performed auditory-perceptual ratings while the subject read an oral passage under all conditions. Results: Kruskal-Wallis test showed significant difference among conditions (p=0.0002), with Scheffe post hoc test indicating difference from the no-opening condition. Conclusion: The changes in nasalance observed after drilling holes of known sizes in a speech bulb suggest that nasometry reflect changes in transfer of sound energy related to different sizes of velopharyngeal opening.

Nasoendoscopy of velopharynx before and during diagnostic therapy

Nasoendoscopy is an important tool for assessing velopharyngeal function. The purpose of this study was to analyze velar and pharyngeal wall movement and velopharyngeal gap during nasoendoscopic evaluation of the velopharynx before and during diagnostic therapy. Nasoendoscopic recordings of 10 children with operated cleft lip and palate were analyzed according to the International Working Group Guidelines. Ratings of movement of velum and pharyngeal walls, and size, location and shape of gaps were analyzed by 3 speech-language pathologists (SLPs). Imaging was obtained during repetitions of the syllable /pa/ during a single nasoendoscopic evaluation: (a) before diagnostic therapy, and (b) after the children were instructed to impound and increase intraoral air pressure (diagnostic therapy). Once the patients impounded and directed air pressure orally, the displacement of the velum, right, left and posterior pharyngeal walls increased 40, 70, 80, and 10%, respectively. Statistical significance for displacement was found only for right and left lateral pharyngeal walls. Reduction in gap size was observed for 30% of the patients and other 40% of the gaps disappeared. Changes in gap size were found to be statistically significant between the two conditions. In nasoendoscopic assessment, the full potential of velopharyngeal displacement may not be completely elicited when the patient is asked only to repeat a speech stimulus. Optimization of information can be done with the use of diagnostic therapy's strategies to manipulate VP function. Assuring the participation of the SLP to conduct diagnostic therapy is essential for management of velopharyngeal dysfunction.

Avaliação da eficiência da técnica de obturação pela compressão hidrùlica vertical após instrumentação automatizada

The purpose of this study was to evaluate through radiographic and microscopic analysis the efficiency of the filling techniques by vertical hidraulic compression after the root canal mechanical instrumentation in vitro as well to evaluate the marginal apical leakage through macroscopic and microscopic analysis. Thirty human mandibular molars were used , they were divided on three groups, these were subdivided on six subgroups with five specimens each, come down to 106 root canals filled. Initially, the teeth were instrumented with Profile system series 29 and filled with two ways: single accessory cone or single cone associated with gutta-percha secundary cone, with Fill Canal sealer or Sealer 26. Completed the filling, the teeth were coated with araldit and finger -nail polish except for the apical 2 mm and dried for 3 hours, thep radiographs were taken of the teeth in orto and disto-radiai directions. Next, the coronal seal was carried out with composite resin photopolymerized and with their process of making impermeable. Teeth of positive controls were used without araldit and finger-nail polish whereas the negative controls were used with total coat of araldit and finger-nail polish. The specimens were placed in 2% Methylene Blue dye for 24 hours and thermocycled for 7 days. Afterwards, sections were made of each tooth at mesial and distal roat, after this the teeth were radiographed at buccolíngual direction for a macroscopic analysis and at buccolingual and mesiodistal directions for assessment of the marginal apical leakage. Cross sections were made 3 mm to 3mm since the tooth apice. The sections obtained for each group were observed with a stereomicroscope to evaluate the quality of the root canal filling and the marginal apical leakage. The results showed that: In the four techniques the marginal dye leakage was present in the apical third; in all groups the quality of the root canal filling in the radiography was better at mesial root canal and the single cone technique showed inefficient when only a single distal root canal was present. In the radiographic evaluation the best quality of the root canal filling was observed in the 1A group (single accessory cone + FiIl Canal), as in the mesial root as in the distal root wich Shcwed twe root canals: when the distaI root had only one canal. the best result was showed by 28 group (single accessory cone associated with secundary cone + Fill Canal) In the macroscopic analysis of longitudinal !eaKage (outside surface). less leakage was showed as In the mesial root as in the distal root in the negative control group (3) followed 2A group (single accessory cone + Sealer 26). When the microscopic analysis of tranversal leakage of both roots (inside surface) was carried out. the groups that showed less dye leakage were the negative control (38) followed the 28 group (single acessory cone associated with secundary cone + Sealer 26). The homogeneity o filling was best noted in the 1 A group (.single accessoty cone + Fill Canal). The groups that showed less dye penetration in the tranversal leakage (total area) were negative control (3B) and 2B

Análises clínicas, radiográfica e microscópica de molares permanentes sem ou com lesão de cárie na superfície oclusal

O presente trabalho, objetivou avaliar comparativamente o diagnóstico clínico, radiógráfico e histológico de molares permanentes humanos sem ou com lesão de cárie na superfície oclusa!. Vinte e quatro dentes que estavam armazenados em formalina a 10% foram selecionados e em seguida submetidos a um exame clínico, através da inspeção visual, onde foram separados em 3 grupos: grupo 1 (G1), formado por dentes hígidos; grupo 2(G2), por dentes com pigmento na superfície oclusal e grupo 3(G3), aqueles com lesão de cárie na oclusal. Este exame foi realizado com auxílio de luz artificial proveniente de um refletor odontológico, sem qualquer manipulação da superfície. Para cada dente foram realizados duas tomadas radiográficas com e sem tela milimetrada, no sentido vestibulo lingual por um dos avaliadores, simulando uma radiografia interproximal, onde o feixe incidiu perpendicular ao longo eixo do dente. Em seguida os dentes foram preparados histomorfologicamente para coloração com hematoxilina e eosina e análise microscópica. Pela avaliação dos resultados a partir da amostra de 100%, foi possível concluir: 1) Os dentes clinicamente considerados hígidos (G1) apresentaram radiograficamente 74,99% de ausência de imagem radiolúcida e em 25% presença desta imagem na Junção Amelo¬dentinária e microscopicamente ausência de cárie em 100%; 2) os dentes que clinicamente apresentaram fissura pigmentada' (G2) notou-se em 33,33%, ausência da imagem radiolúcida e em 66,66% presente esta imagem na junção amelodentinária, 100% de ausência de cárie através da análise microscópica; 3) clinicamente, os dentes que apresentaram lesão de cárie (G3), radiograficamente foram comprovados 100% de imagem radiolúcida sugestiva de cárie e microscopicamente dos 100% destas, foram considerados cáries rasa (16,66%), média (61,10%) e profunda (22,22%) respectivamente

Análise imuno-histoquímica de proteínas relacionadas às respostas Th1, Th2 e Th17 na doença periodontal

Periodontal disease is an inflammatory condition of infectious nature characterized by destruction of protecting and supporting dental tissues. It happens as a response produced by the host when attacked by microorganisms. Several factors are involved in this process. Among them, cytokines are key regulatory molecules in this immune response, playing a role either protective and/or destructive in lesion progression. Thus, this study investigated the immunohistochemical expression of IFN- , GATA-3, IL-17, IL-23, IL-6 and TGF- in gingival tissues of humans, in an attempt to gain a better understanding of the participation of Th1, Th2 and Th17 immune responses in the development of periodontal disease processes. To this end, eighty-two samples of gingival tissues were divided into three groups: Group 1 = 15 (samples of healthy gum tissue as controls), Group 2 = 36 (samples with chronic gingivitis) and Group 3 = 31 (samples with chronic periodontitis). All cases were submitted to morphological analysis from sections stained with hematoxylin and eosin and then subjected to staining by immunohistochemistry using the streptavidin-biotin method. Results showed positive labeling for all proteins. Nonetheless, we observed a greater expression of Th1 cytokines and Th17 cells in group 3. We found statistically significant difference between TGF- expression and the clinical condition of the samples (p=0.02). We conclude that Th1 and Th17 responses may act synergistically in the destructive process of periodontal tissue, overlapping the Th2 response that was also present in these tissues

Estudo imuno-histoquímico da presença de miofibroblastos e da expressão do fator transformador de crescimento-beta1, interferon gama, metaloproteinase de matriz 13 e indutor de metaloproteinases de matriz em lesões odontogênicas epiteliais

Myofibroblasts are cells that exhibit a hybrid phenotype, sharing the morphological characteristics of fibroblasts and smooth muscle cells, which is acquired during a process called differentiation. These cells then start to express -SMA, a marker that can be used for their identification. Studies suggest that myofibroblasts are related to the aggressiveness of different tumors and that TGF-1 and IFN- play a role in myofibroblast differentiation, stimulating or inhibiting this differentiation, respectively. The objective of this study was to investigate the role of myofibroblasts in epithelial odontogenic tumors, correlating the presence of these cells with the aggressiveness of the tumor. Immunohistochemistry was used to evaluate the expression of TGF-1 and IFN- in myofibroblast differentiation, as well as the expression of MMP-13, which is activated by myofibroblasts, and of EMMPRIN (extracellular matrix metalloproteinase inducer) as a precursor of this MMP. The sample consisted of 20 solid ameloblastomas, 10 unicystic ameloblastomas, 20 odontogenic keratocysts, and 20 adenomatoid odontogenic tumors. For evaluation of myofibroblasts, anti- -SMA-immunoreactive cells were quantified in connective tissue close to the epithelium. Immunoexpression of TGF-1, IFN-, MMP-13 and EMMPRIN was evaluated in the epithelial and connective tissue components, attributing scores of 0 to 4. The results showed a higher concentration of myofibroblasts in solid ameloblastomas (mean of 30.55), followed by odontogenic keratocysts (22.50), unicystic ameloblastomas (20.80), and adenomatoid odontogenic tumors (19.15) (p=0.001). No significant correlation between TGF-1 and IFN- was observed during the process of myofibroblast differentiation. There was also no correlation between the quantity of myofibroblasts and MMP-13 expression. Significant correlations were found between MMP-13 and TGF-1 (r=0.087; p=0.011), between MMP- 13 and IFN- (r=0.348; p=0.003), as well as between EMMPRIN and MMP-13 (r=0.474; p<0.001) and between EMMPRIN and IFN- (r=0.393; p=0.001). The higher quantity of myofibroblasts observed in solid ameloblastomas, odontogenic keratocysts and unicystic ameloblastomas suggests that these cells are one of the factors responsible for the more aggressive biological behavior of these tumors, although the myofibroblast population was not correlated with TGF-1, IFN-, MMP-13 or EMMPRIN. The correlation between MMP- 13 and TGF-1 suggests that the latter induces the expression of this metalloproteinase. The present results also support the well-established role of EMMPRIN as an inducer of MMP-13. Furthermore, the relationship between EMMPRIN and IFN- and between MMP-13 and IFN- suggests synergism in the antifibrotic effect of these markers

Efeitos da laserterapia na atividade biológica de células de carcinoma epidermóide de língua humano

The low level laser therapy (LLLT) has shown to be effective in promoting the proliferation of different cells in vitro, including keratinocytes, osteoblasts, endothelial cells and stem cells. It has been speculated that the biostimulatory effect of LLLT could cause undesirable enhancement of tumor growth in neoplastic diseases, since the malignant cells are more susceptible to proliferative stimuli. Within this context, this study evaluated the effect of LLLT on epidermoid carcinoma of the tongue cell line (SCC25) proliferation and invasion. Cultured cells were irradiated with an InGaAIP diode laser, 660nm, 30mW using two energy densities (0.5J/cm2 and 1.0J/cm2). Proliferative activity was assessed through trypan blue staining method and through cell cycle analysis using flow cytometry. The invasive potential was measured through cell invasion assay using matrigel. Cyclin D1, E-cadherin, -catenin and MMP-9 expressions were analyzed by immunofluorescence and flow cytometry and related to the investigated biological activities. Proliferation curve demonstrated that SCC25 irradiated with 1.0J/cm2 had the highest proliferative rate when compared to the control group and the group irradiated with 0.5J/cm2 (p<0.05). LLLT affected cell cycle distribution and energy density of 1.0 J/cm2 promoted a higher percentage of cells in S/G2/M phases, with statistically significant differences at 24h interval (p<0.05). LLLT, mainly with 1.0J/cm2, revealed significantly higher potential for invasion and influenced the expression of cyclin D1, E-cadherin, -catenin and MMP-9, promoting the malignant phenotype. In conclusion, our results indicate that LLLT has an important stimulatory effect on proliferation and invasion of SCC25 cells, likely due to altered expression of proteins associated with these processes

Pobreza e desigualdades socioterritorias: uma problematização acerca da perspectiva territorial nas politicas públicas sociais no município de Pau dos Ferros/RN

El presente trabajo se constituye en un estudio sobre la pobreza y las desigualdades socio territoriales en el Brasil, problematizando la perspectiva territorial de las políticas públicas sociales observando la distribución espacial del Índice de Desarrollo de las familias (IDF) en el municipio de Pau dos Ferros/RN, así como las principales políticas sociales, a ejemplo del Programa Bolsa Familia. En este sentido, el objetivo principal de esa disertación se dió en la tentativa de comprender la importancia de la lectura previa del territorio para la reflexión sobre la pobreza en su aspecto multidimensional y para la territorialización de las políticas Públicas sociales construidas en el intento de minimizar la problemática de la desigualdad social, observando la distribución espacial do IDF en el municipio de Pau dos Ferros/RN. A partir del objetivo general trazado, hicimos una revisión teórica sobre los temas, pobreza, desigualdades sociales y políticas públicas, en el primero caso atentando para el aspecto multidimensional de esta, abogando la importancia de analizarnos la pobreza no apenas por el nivel de rienda, pero considerando otras dimensiones que corroboran para la constitución del ser pobre, como habitaciones precarias, falta de saneamiento básico e infraestructura, el no acceso a la salud, la educación y los otros servicios que posibilitan el individuo vivir con el mejor dignidad. Comprendiendo la importancia del conocimiento previo del territorio para que ocurra las debidas reflexiones e intervenciones en la realidad territorial buscamos reflexionar acerca de ese concepto en sus nexos con la construcción e implementación de las políticas públicas sociales teniendo la Política Nacional de Asistencia Social (PNAS) como política esencial y también el el Programa Bolsa Familia (PBF), una vez que buscamos compreender su importancia a partir de la visión del sujeto, o sea las beneficiadas del PBF en el Municipio de Pau dos Ferros. Para tanto, hicimos entrevistas orales con las beneficiadas del PBF que fueron elegidas aislada a partir de los equipos del CRAS, además de la aplicación de cuestionarios semiesctructurados y abiertos con gestores y asistentes sociales del muninicipio.Buscamos además trabajar con algunos datos del CadÚnico para el município en estudio proponiendo analisar las condiciones sociales y económicas de las famílias cadastradas. Algunos resultados fueron posibles, a saber, es necesario interpretarse la pobreza a partir de varias dimensiones para no tener el riesgo de quedarnos solamente en la perspectiva financiera, o sea de la rienda, que mismo sirva para lo emergencial no es suficiente para transformar las condiciones de vida de las famílias; PNAS puede ser considerada como un avanzo de la política social en el Brasil una vez que posuye importancia fundamental en la familia. Sin embargo, es preciso avanzar en la interpretación del territorio que en la política y en el habla de los agentes sociales , es interpretación apenas como un recorte donde deberán ocurrir las acciones para minimizar la pobreza ; al fin, o PBF es un programa de urgencia moral una vez que combate lo mas emergencial que es el directo de sobrevivir , pero aun no conseguió transformar de una manera significativa la pobreza en el país

Técnicas radiográficas intra e extrabucal na avaliação dentária de cães com doença periodontal

Foram avaliadas as técnicas radiográficas dentárias intra (TIB) e extrabucal (TEB) em 50 cães com doença periodontal, no intuito de padronizar os procedimentos de diagnóstico dessa síndrome. A TIB revelou que 16 animais não apresentaram lesões ósseas visíveis, enquanto a TEB apontou que 39 pacientes foram negativos para as mesmas lesões. em resumo, a TIB foi mais eficaz na detecção de sinais radiográficos, especialmente as chamadas lesões finas, que a TEB, sendo a técnica de escolha na síndrome periodontal.
