Published: January 2013

This study evaluated the influence of material combinations used in the resin coating technique (RCT) on the marginal adaptation of indirect restorations with gingival margins in enamel (EM) and cement (CM). Eighty third-molars were used. Two cavities were prepared in each tooth. The cavities were distributed into 16 groups. Cavities with EM were filled with the following material combinations: G1: Single-Bond 2 (Sb2), G2: Sb2 + Bond/Scotchbond-Multipurpose (Sb2B), G3: Sb2 + Filtek-Flow Z350 (Sb2Fl), G4: Scotchbond-Multipurpose (SBMP), G5: Clearfil-S3 (CS3), G6: CS3 + Bond/Clearfil-SE Bond (CSE3B), G7: CS3 + Protect Liner F (CS3PL) and G8: Clearfil SE Bond + Protect Liner F (CSEBPL). The same combinations were applied to the cavities in CM: G9, G10, G11, G12, G13, G14, G15, G16, respectively. The fillings were performed with the Sinfony-System (3M/ESPE). After 24 h, the teeth were submitted to thermocycling (2,000 cycles, 5° to 55°C) and load-cycling (50,000 cycles, 50 N). Next, the Caries-Detector (Kuraray) was applied to the restoration margins. Images from the proximal margin were evaluated using the Image-Tool 3.0 software. The results were submitted to ANOVA and Tukey's test (α=0.05). The mean values (%) for the groups were: EM: G1=46.68, G2=15.53, G3=19.83, G4=27.53; G5=59.49, G6=25.13, G7=34.37, G8=15.20; CM: G9=38.38, G10=23.25, G11=26.97, G12=25.85, G13=37.81, G14=30.62, G15=29.17, G16=20.31. The highest percentages of marginal gap on EM or CM were found in the groups that did not use a liner. It can be concluded that the most appropriate RCT combinations were the groups that used a liner.

The aim of this study was to assess the influence of surface pretreatments of fiber-reinforced posts on flexural strength (FS), modulus of elasticity (ME) and morphology of these posts, as well as the bond strength (BS) between posts and core material. Fifty-two fiber posts (smooth and serrated) were assigned to 4 groups (n=13): no treatment (control), 10% hydrogen peroxide (HP) for 10 min (HP-10), 24% HP for 1 min (HP-24) and airborne-particle abrasion (Al2O3). To evaluate FS and ME, a 3-point bending test was performed. Three posts of each group were examined by scanning electron microscopy. Composite resin was used as the core build-up and samples were sectioned to obtain microtensile sticks. Data were analyzed by ANOVA and Tukey's test (α=0.05). For FS, significant differences were observed between posts type and surface pretreatment (p<0.05), with the highest means for the smooth posts. Al2O3 provided higher FS than HP-24. Al2O3 promoted higher ME than HP-24 and control. SEM images revealed partial dissolution of the resin matrix in all treated groups. The smooth posts had higher BS and FS than serrated posts (p<0.05). Mechanical properties of the glass fiber posts and the bond strength between posts and composite material were not altered by the surface treatments, except for airborne-particle abrasion that increased the post elastic modulus.

The aim of this study was to assess the effect of different plasma arc welding parameters on the flexural strength of titanium alloy beams (Ti-6Al-4V). Forty Ti-6Al-4V and 10 NiCr alloy beam specimens (40 mm long and 3.18 mm diameter) were prepared and divided into 5 groups (n=10). The titanium alloy beams for the control group were not sectioned or subjected to welding. Groups PL10, PL12, and PL14 contained titanium beams sectioned and welded at current 3 A for 10, 12 or 14 ms, respectively. Group NCB consisted of NiCr alloy beams welded using conventional torch brazing. After, the beams were subjected to a three-point bending test and the values obtained were analyzed to assess the flexural strength (MPa). Statistical analysis was carried out by one-way ANOVA and Tukey's HSD test at 0.05 confidence level. Significant difference was verified among the evaluated groups (p<0.001), with higher flexural strength for the control group (p<0.05). No significant differences was observed among the plasma welded groups (p>0.05). The NCB group showed the lowest flexural strength, although it was statistically similar to the PL 14 group (p>0.05). The weld depth penetration was not significantly different among the plasma welded groups (p=0.05). Three representative specimens were randomly selected to be evaluated under scanning electron microcopy. The composition of the welded regions was analyzed by energy dispersive X-ray spectroscopy. This study provides an initial set of parameters supporting the use of plasma welding during fabrication of titanium alloy dental frameworks.

This study evaluated the effectiveness of different sealants applied to a nanofiller composite resin. Forty specimens of Filtek Z-350 were obtained after inserting the material in a 6x3 mm stainless steel mold followed by light activation for 20 s. The groups were divided (n=10) according to the surface treatment applied: Control group (no surface treatment), Fortify, Fortify Plus and Biscover LV. The specimens were subjected to simulated toothbrushing using a 200 g load and 250 strokes/min to simulate 1 week, 1, 3 and 6 months and 1 and 3 years in the mouth, considering 10,000 cycles equivalent to 1 year of toothbrushing. Oral-B soft-bristle-tip toothbrush heads and Colgate Total dentifrice at a 1:2 water-dilution were used. After each simulated time, surface roughness was assessed in random triplicate readings. The data were submitted to two-way ANOVA and Tukey's test at a 95% confidence level. The specimens were observed under scanning electron microscopy (SEM) after each toothbrushing cycle. The control group was not significantly different (p>0.05) from the other groups, except for Fortify Plus (p<0.05), which was rougher. No significant differences (p>0.05) were observed at the 1-month assessment between the experimental and control groups. Fortify and Fortify Plus presented a rougher surface over time, differing from the baseline (p<0.05). Biscover LV did not differ (p>0.05) from the baseline at any time. None of the experimental groups showed a significantly better performance (p>0.05) than the control group at any time. SEM confirmed the differences found during the roughness testing. Surface penetrating sealants did not improve the roughness of nanofiller composite resin.

The aim of this in vitro study was to evaluate the shear bond strength of brackets after pre-treatment with different fluoride solutions. This study used 48 freshly extracted sound bovine incisors that were randomly assigned to 4 experimental groups (n=12). CG: (control) without treatment; NF: 4 min application of neutral fluoride; APF: application of 1.23% acidulated phosphate fluoride (APF) for 4 min; and SFV: application of 5% sodium fluoride varnish for 6 h. For each group, after surface treatment, prophylaxis of enamel and bracket bonding with Transbond XT composite resin (3M) were performed following the manufacturer's specifications. The shear bond strength was performed with a universal testing machine 24 h after fixing the brackets. The tooth surfaces were analyzed to verify the adhesive remnant index (ARI). Data were analyzed statistically by ANOVA and Tukey's test (α=0.05). There was statistically significant difference among the groups (p<0.0001). CG and NF groups presented significantly higher bond strength than APF and SFV. There was no significant difference between CG and NF or between APF and SFV (p>0.05). The analysis of ARI scores revealed that most failures occurred at the enamel-resin interface. It may be concluded that the pre-treatment of enamel with 1.23% APF and 5% SFV prior to fixing orthodontic brackets reduces shear bond strength values.

Published: January 2013

The aim of this study was to assess the applicability of gray scale inversion in performing digital linear endodontic measurements. Standardized digital images were taken of 40 extracted human permanent single-rooted teeth with K-files size 15 placed at different lengths in the root canal, using the CDR Wireless® digital system. All images were treated with Positive, a digital tool that inverts the grayscale value. Eight radiologists measured the distance between the lower limit of the rubber stop and the tip of the file on both original and positive images. After 15 days, they repeated this procedure in 50% of the image samples. The intra- and inter-examiner agreement was analyzed by intraclass correlation test, and the comparison between the two image groups and the actual lengths by the Student's t-test (α=0.05). Intra- and inter-examiner evaluation showed high reproducibility (r>0.95) of both original and positive images. No statistically significant differences (p>0.05) were found between measurements performed on original and positive images, but both differed significantly from the actual lengths (p<0.05). Gray scale inversion has low applicability in measuring endodontic files, since it did not improve the accuracy of measurements.

Published: January 2013

Lymphangiomas are benign hamartomatous lesions of lymphatic vessels. Wilms Tumor 1 (WT1) is a transcription factor that is activated in some human neoplasias. WT1 protein expression is observed in endothelial cells during angiogenesis and is a useful marker to distinguish between vascular proliferations and vascular malformations. The purpose of the present study is to report a case series of oral lymphangiomas together with an immunohistochemical investigation of WT1. Seventeen cases of oral lymphangioma were retrieved and reviewed. Immunohistochemical analysis of WT1 protein was performed and pyogenic granuloma samples were used as positive controls. The male/female ratio was 1.125 and most of the lesions occurred in young subjects. While pyogenic granuloma showed positive staining for WT1, the endothelial cells lining the thin-walled dilated lymphatic vessels of lymphangiomas were negative for this protein. The findings strengthen the idea that oral lymphangioma is a vascular malformation characterized by lymphatic dilatation without significant endothelial proliferation.

Published: January 2013

Despite high cure rates, approximately 20% of patients with acute lymphoblastic leukemia (ALL) have disease relapse. Isolated recurrence in oral cavity is extremely unusual. The aim of this paper is to report a case of an isolated relapse occurred in a child with T-lineage ALL. Clinical picture included swelling and pain in the right upper gingiva of the oral cavity, with no other clinical or hematological alterations. Diagnosis was confirmed by biopsy and immunohistochemical staining. Bone marrow aspiration was normal. Five months later leukemic infiltration of the bone marrow was detected and systemic chemotherapy was reintroduced. This case report highlights the relevance of dental care during and after chemotherapy, not only to treat lesions in the oral cavity resulting from the disease itself or from treatment side effects, but also to detect unusual sites of ALL relapse.

This study aimed to evaluate the effects of fluconazole or nystatin exposure on developed Candida albicans biofilms regarding their exopolysaccharide matrix. The minimal inhibitory concentration (MIC) against fluconazole or nystatin was determined for C. albicans reference strain (ATCC 90028). Poly(methlymethacrylate) resin (PMMA) specimens were fabricated according to the manufacturer's instructions and had their surface roughness measured. Biofilms were developed on specimens surfaces for 48 h and after that were exposed during 24 h to fluconazole or nystatin prepared in a medium at MIC, 10 x MIC or 100 x MIC. Metabolic activity was evaluated using an XTT assay. Production of soluble and insoluble exopolysaccharide and intracellular polysaccharides was evaluated by the phenol-sulfuric method. Confocal laser scanning microscope was used to evaluate biofilm architecture and percentage of dead/live cells. Data were analyzed statistically by ANOVA and Tukey's test at 5% significance level. The presence of fluconazole or nystatin at concentrations higher than MIC results in a great reduction of metabolic activity (p<0.001). At MIC or 10 x MIC, fluconazole showed high amounts of intracellular polysaccharides (p<0.05), but did not affect the exopolysaccharide matrix (p>0.05). The exposure to nystatin also did not alter the exopolysaccharide matrix at all the tested concentrations (p>0.05). Biofilm architecture was not affected by either of the antifungal agents (p>0.05). Nystatin promoted higher proportion of dead cells (p<0.05). It may be concluded that fluconazole and nystatin above the MIC concentration reduced the metabolic activity of C. albicans biofilms; however, they were not able to alter the exopolysaccharide matrix and biofilm architecture.

Published: January 2013

This studyevaluated protection by selenium (Se) in the bone repair process in ovariectomized rats after irradiation. For such purpose, 80 ovariectomized female Wistar rats were randomly divided into 4 experimental groups: ovariectomized (Ov), Ov/Se, Ov/irradiated (Irr) and Ov/ Se/Irr. A bone defect was created on the tibia of all animals 40 days after ovariectomy. Two days after surgery, only the Ov/Se and Ov/Se/Irr rats received 0.8 mg Se/kg. Three days after surgery, only the Ov/Irr and Ov/Se/Irr rats received 10 Gy of x-rays on the lower limb region. The animals were euthanized at 7, 14, 21 and 28 days after surgery to assess the repair process, which was evaluated by analysis of trabecular bone number (Masson Trichrome) and birefringence analysis (Picrosirius). It was possible to observe a delay in the bone repair process in the ovariectomized/irradiated group and similarity between the ovariectomized, Ov/Se and Ov/Se/Irr groups. In conclusion, sodium selenite exerted a radioprotective effect in the bone repair of tibia of ovariectomized rats without toxicity.

This study evaluated the perceptions of Brazilian undergraduate dental students about the endodontic treatments performed using NiTi rotary instruments and hand stainless steel. Data were collected using a questionnaire administered to undergraduate dental students enrolled in endodontic disciplines. The students were divided into 3 groups: G1, students who had treated straight canals with SS hand instruments; G2, students who had treated curved canals with SS hand instruments; and G3, students who had treated both straight and curved canals with NiTi rotary instruments. The number of endodontic treatments performed, types of treated teeth, students' learning, time spent, encountered difficulties, quality of endodontic treatment and characteristics of the employed technique were analyzed. There was a 91.3% rate of return for the questionnaires. Mandibular molars were the most frequently treated teeth, followed by maxillary incisors. The Kruskal-Wallis test showed no differences in learning (p=0.528) or in the characteristics of the technique employed (p=0.560) among the three groups. G3 students performed a greater number of endodontic treatments (p<0.001) in a smaller time (p<0.001) than did G1 and G2 students. Difficulties were reported primarily by students in G2 and G3 compared with G1 (p=0.048). The quality of endodontic treatments differed only between G1 and G2 (p=0.045). The use of NiTi rotary instruments should be included in undergraduate dental curriculum, contributing to the increase of patients assisted and consequently to improve the clinical experience of the students.

Published: January 2013

The aim of the study was to determine factors associated with changes in self-reported dentifrice consumption in an urban population group over 13 years. This study evaluated two surveys of 671 and 688 households sampled in the urban area of a city from Southern Brazil in 1996 and 2009, respectively. The mother of the family was asked to answer a structured questionnaire about demographics, socioeconomic and behavioral variables. The primary outcome was obtained by questioning "how long does a dentifrice tube last in your house?" The cut-off point of duration was less than 1 month. It was used to determine high consumption of dentifrice (HCD). Associations between HCD and independent variables were evaluated by multivariable Poisson regression. There was a significant decrease of 20% (81.2% to 61.2%) in the prevalence of HCD between 1996 and 2009, resulting in a crude annual decrease of 1.54%. Mother's age, family income, dental assistance, mother's brushing frequency and number of household members that use a toothbrush were significantly associated with HCD independent from the year of survey. The prevalence ratio (PR) of HCD for the year of survey was 0.75, indicating an overall decrease of 25% in the probability of HCD from 1996 to 2009. Probabilities of HCD also decreased over the 13 years among the strata of education, number of household members and reason for choice of dentifrice. It may be concluded that the factors associated with the observed decrease were higher educational levels, larger number of household members and reasons for choosing a dentifrice related to preventive/therapeutic effects.

Bruxism is the non-functional clenching or grinding of the teeth that may occur during sleep or less commonly in daytime. The aim of this study was to investigate the association between clinical signs and symptoms, parafunctions and associated factors of sleep bruxism in children. A population-based case-control study was carried out involving 120 children, 8 years of age, with sleep bruxism and 240 children without sleep bruxism. The sample was randomly selected from public and private schools in the city of Belo Horizonte, MG, Brazil. Groups were matched by gender and social class. The Social Vulnerability Index (SVI) drawn up by the city of Belo Horizonte was employed for social classification. Data collection instruments included clinical forms and pre-tested questionnaires. The diagnosis of sleep bruxism was supported by the American Association of Sleep Medicine (AASM) criteria. The McNemar test, binary and multivariate logistic regression models were used for statistical analysis. The risk factors associated with sleep bruxism included: primary canine wear (OR=2.3 IC 95% 1.2-4.3), biting of objects like pencils or pens (OR=2.0 IC 95% 1.2-3.3) and wake-time bruxism (tooth clenching) (OR=2.3 IC 95% 1.2-4.3). Children that present the parafunctions of object biting and wake-time bruxism were more susceptible to sleep bruxism.

Published: January 2013

South American blastomycosis, paracoccidioidomycosis (Pb mycosis) or Lutz disease is an endemically fungal infection in Latin America. It is caused by the dimorphic fungus Paracoccidioides brasiliensis and may cause oral mucosal lesions. The incidence of Pb mycosis oral lesions was evaluated in patients assisted at a Brazilian Dental School's Specialized Oral Diagnosis Service with special focus on the different clinical forms of these lesions, its location, patients' occupation, deleterious habits, and diagnosis methodology. Students' and professionals' initial diagnoses were compared with the definitive diagnosis. Lesions were detected 31 cases (18 patients). The results show that 88.8% of the patients were male with a mean age of 50 years and 39% work(ed) with activities related to agriculture. As much as 88.9% were smokers and 72.2% were alcohol users. Exfoliative cytology was performed in 66.6% of the patients. Oral mucosa (30%), gingiva (16.6%) and lips 16.6% were the most common sites of Pb mycosis oral lesions. Comparing the initial with the definitive diagnosis made by the professionals their accuracy was 33% (6 out of 18 patients). Students' diagnosis was more accurate demonstrating 72.5% of initial correct diagnosis (13 out of 18). Statistical analysis by ANOVA (α=0.05, SPSS WIN) demonstrated a significant difference between the diagnosis of Pb mycosis made by students and professionals when considering initial diagnosis and final diagnosis (after histopathological analysis) (p=0.25). Incisional biopsy and exfoliate cytology are efficient for an early diagnosis of this disease in mouth. Students' training in diagnosis of oral pathologies to recognize lesions is urgent to improve public health.

One of the main purposes of mucogingival therapy is to obtain full root coverage. Several treatment modalities have been developed, but few techniques can provide complete root coverage in a class III Miller recession. Thus, the aim of this case report is to present a successful clinical case of a Miller class III gingival recession in which complete root coverage was obtained by means of a multidisciplinary approach. A 17-year-old Caucasian female was referred for treatment of a gingival recession on the mandibular left central incisor. The following procedures were planned for root coverage in this case: free gingival graft, orthodontic movement by means of alignment and leveling and coronally advanced flap (CAF). The case has been followed up for 12 years and the patient presents no recession, no abnormal probing depth and no bleeding on probing, with a wide attached gingiva band. A compromised tooth with poor prognosis, which would be indicated for extraction, can be treated by orthodontic movement and periodontal therapy, with possibility of 100% root coverage in some class III recessions.

Eruption sequestrum is an uncommon disturbance in eruption and consists of small fragments of calcified tissue overlying the crowns of erupting permanent molar teeth, especially at the time of eruption of the mandibular first molars. This paper reports a case of unilateral eruption sequestrum in a 7-year-old Brazilian boy and describes its histopathological findings. A white small fragment, 0.5 cm in diameter, with hard consistency, irregular shape and located on the occlusal surface of the erupting mandibular left first molar was excised. Microscopic examination revealed large trabeculae with empty lacunae and a minimal amount of existing spongy bone consisting of acute inflammatory cells (neutrophils). Signs of necrosis were found on the periphery. The histological analysis was consistent with non-vital bone and the diagnosis of eruption sequestrum was established. Clinical and radiographic follow-up visits scheduled at short intervals and then every 6 months revealed normal postoperative conditions.

Published: January 2013

Open bite has fascinated Orthodontics due to the difficulties regarding its treatment and maintenance of results. This anomaly has distinct characteristics that, in addition to the complexity of multiple etiological factors, have aesthetic and functional consequences. Within this etiological context, several types of mechanics have been used in open bite treatment, such as palatal crib, orthopedic forces, occlusal adjustment, orthodontic camouflage with or without extraction, orthodontic intervention using mini-implants or mini-plates, and even orthognathic surgery. An accurate diagnosis and etiological determination are always the best guides to establish the objectives and the ideal treatment plan for such a malocclusion. This report describes two cases of open bite. At the end of the treatment, both patients had their canines and molars in Class I occlusion, normal overjet and overbite, and stability during the posttreatment period.

Published: January 2013

The American Academy of Orofacial Pain (AAOP) defines ankylosis of the temporomandibular joint (TMJ) as a restriction of movements due to intracapsular fibrous adhesions, fibrous changes in capsular ligaments (fibrous-ankylosis) and osseous mass formation resulting in the fusion of the articular components (osseous-ankylosis). The clinical features of the fibrous-ankylosis are severely limited mouth-opening capacity (limited range of motion during the opening), usually no pain and no joint sounds, marked deflection to the affected side and marked limitation of movement to the contralateral side. A variety of factors may cause TMJ ankylosis, such as trauma, local and systemic inflammatory conditions, neoplasms and TMJ infection. Rheumatoid arthritis (RA) is one of the systemic inflammatory conditions that affect the TMJ and can cause ankylosis. The aim of this study is to present a case of a female patient diagnosed with bilateral asymptomatic fibrous-ankylosis of the TMJ associated with asymptomatic rheumatoid arthritis. This case illustrates the importance of a comprehensive clinical examination and correct diagnosis of an unusual condition causing severe mouth opening limitation.

Published: January 2013

Visando entender qual seria a situação das entidades que atendem a crianças e a adolescentes na atualidade, bem como a trama institucional que compõe esses estabelecimentos, procuramos formular um conjunto de possibilidades paradigmáticas que nos permitisse compreender como se configura o campo dialético de pulsações diversas, no qual as entidades estão situadas. Detectamos as figuras que associamos aos paradigmas homólogos da Caridade, da Promoção Humana, da Filantropia, do Clientelismo Assistencialista, da Assistência Social como Política de Estado e, finalmente, outro conjunto de acontecimentos que propomos designar como paradigma do Sujeito Cidadão, que associamos à perspectiva ética da Educação Popular. Tais possibilidades paradigmáticas vão das simplesmente diversas e contrárias, incluindo as similares e concorrentes, até as dialeticamente contraditórias. Seu espectro oscila entre a tutela e a cidadania. A caracterização didática desses paradigmas pode fornecer uma bússola, necessária num campo social altamente complexo, permitindo compreender a variedade dos efeitos éticos que promovem no campo social.
A captura da subjetividade pela violência simbólica da indústria cultural: da submissão à culpabilidade dos indivíduos
Authors: Caniato Angela , Cesnik Claudia Cotrim , Rodrigues Samara Megume
Published: January 2013

Neste artigo adentramos a profundidade do conceito de indústria cultural, cunhado por Horkheimer e Adorno (1985), para atravessar suas imbricações com as fantasias inconscientes, em especial as de natureza destrutiva. A violência simbólica da indústria cultural, quando internalizada pelos indivíduos, veicula os modelos identificatórios exigidos pela sociedade de consumo para universalizar a lógica da mercadoria entre todos eles. Essa perversão nos processos de constituição das subjetividades conduz às suas estandardizações nos moldes que Theodor Adorno identifica como de pseudoindivíduos, atados simbioticamente uns aos outros. Existe uma similaridade entre esses conceitos adornianos e o de “sentimento inconsciente de culpabilidade” de Freud, em que esse autor identifica processos de autopunição subjetiva quando, sob a “mais-repressão social”, os indivíduos estão proibidos de reagir. O sadomasoquismo sustenta a cumplicidade dos indivíduos com esse status quo opressor, orquestrado pelo engano das ideologias difundidas pela indústria cultural. Será possível que esses indivíduos venham a assumir as suas criticidades para tornarem-se construtores da cultura?

Published: January 2013

Este artigo propõe um diálogo entre as teorizações psicanalíticas de Sandor Ferenczi e Donald Winnicott a respeito do papel do objeto no psiquismo, tanto em sua dimensão traumática como constitutiva. Serão discutidas as contribuições convergentes dos autores à concepção psicanalítica de trauma e suas vicissitudes no psiquismo. Seguindo uma tradição de valorização do meio ambiente, o trauma passa a ser pensado como falha na relação entre o sujeito e outro.

Este trabalho tem a intenção de abordar o tema da adolescência e estabelecer um campo de diálogo, sob tensão, com saberes que o consideram objeto de pesquisa, como a da sociologia. A partir da diferenciação entre o tema da adolescência como questão subjetiva e adolescência como fenômeno social - diferença nem sempre considerada entre psicanalistas e demais pesquisadores das ciências humanas -, é possível retomar a inscrição histórica do advento da adolescência e fazer o exercício de escuta de discursos de sujeitos que, em seu percurso adolescente, explicitam impasses e tensões da posição que ocupam e almejam garantir na estrutura social que os antecede. Diferentemente do que se poderia supor, a ameaça de exclusão não afeta somente aqueles que pertencem a segmentos socioeconômicos menos favorecidos, mas também os ditos privilegiados, diante da angústia de perda da posição socioeconômica herdada na pirâmide social vigente. A experiência com a formação de jovens nessas condições sociais permitiu a emergência de discursos que denunciam o impasse vivido.
Intimidade e saúde

A intimidade é antecedida de processos ativos, transversais ao ciclo de vida. O vínculo afetivo estabelece-se primariamente na relação de vinculação mãe-bebê, e os padrões comportamentais e estilos de vinculação tendem a repercutir-se nas relações adultas. O objetivo exploratório desta investigação pretende apurar a transcrição física (consequências na saúde) de vivências insatisfatórias de intimidade. Sessenta universitários (30 do sexo feminino; 30 do sexo masculino), com idades entre 22 e 27 anos, envolvidos numa relação amorosa fixa (duração mínima: 6 meses) foram contactados para responder a uma bateria de instrumentos (variáveis de interesse: intimidade, identidade, autoconceito e vinculação). Um bom estado de saúde parece associar-se a valores elevados de interdependência e baixos valores de dependência na relação amorosa. Nestes jovens a intimidade baseada na dependência compromete 14% da saúde mental. O impacto de uma intimidade pouco saudável limita em quase 9% a saúde física de jovens adultos saudáveis.
Corpos precários, desrespeito e autoestima: o caso de moradores de rua de Paris-FR
Authors: Graeff Lucas
Published: January 2013

O presente artigo discute quando e sob quais condições determinados signos corporais podem ser considerados ou não como enunciadores da relação íntima entre o corpo de um “morador de rua” parisiense e o universo no qual ele se encontra. São esses fatores que fazem do cuidado do corpo e de si uma experiência difícil de administrar pelos sujeitos pesquisados. Com efeito, marcado pela relação íntima estabelecida com as condições precárias de existência, a hexis corporal das pessoas estudadas passa a ser tanto objeto de “desrespeito social” quanto fonte negativa de autoestima. Ao final, são delineados caminhos possíveis da “retirada da rua” do corpo - isto é, do trabalho árduo de reabilitação física e moral das pessoas estudadas.
A dimensão política na formação dos profissionais de saúde
Authors: Lobato Carolina Pereira , Melchior Regina , Baduy Rossana Staevie
Published: January 2013

São necessários avanços na implementação do SUS no Brasil. Os trabalhadores da saúde são agentes instituintes de mudança nas práticas do mundo do trabalho. O presente artigo buscou compreender algumas possibilidades para contemplar a dimensão política na formação desses trabalhadores. O território de estudo foi um programa de residência multiprofissional em saúde no interior de São Paulo. Para a produção dos dados, além de observação, foram realizadas 14 entrevistas semiestruturadas com residentes, preceptores, tutores e com a coordenação do programa. A análise foi dividida em potências para a dimensão política nas práticas pedagógicas e nas práticas de gestão da Residência. Encontraram-se potências nos espaços pedagógicos, de gestão e no mundo do cuidado. As tensões dispararam um processo de autoanálise nos sujeitos envolvidos e propiciaram novos arranjos no processo formativo. Evidenciou-se que as residências podem ser dispositivos para a formação de trabalhadores da saúde na defesa do SUS.
Fatores críticos para a fixação do médico na Estratégia Saúde da Família
Authors: Ney Márcia Silveira , Rodrigues Paulo Henrique de Almeida
Published: January 2013

O artigo analisa as condições que interferem na fixação do médico na Estratégia Saúde da Família. Trata-se de pesquisa de natureza qualitativa envolvendo análise documental das políticas de recursos humanos praticadas, aplicação e análise de questionários e grupo focal, visando identificar a percepção dos médicos sobre seu trabalho na estratégia. Revelou-se uma alta rotatividade dos médicos, determinada por insatisfação profissional, condições de trabalho inadequadas e carga de trabalho pesada. Dentre as características da política local de recursos humanos, destacaram-se distorções em relação à remuneração; e problemas no plano de cargos, carreira e salários em relação aos médicos de família, que limitam e penalizam a ascensão do profissional. Os principais motivos identificados na pesquisa que favorecem a permanência foram: identificação com a filosofia da estratégia, vocação profissional e possibilidade de servir à comunidade. São apresentadas reflexões sobre a gestão dos recursos humanos na estratégia e no SUS como um todo, apontando algumas das principais fragilidades da mesma, das quais se destacam: deficiências na política de formação profissional para a especialidade, insuficiente regulação da profissão médica no Brasil por parte do Estado e excessiva interferência política na prestação de serviços públicos de saúde, particularmente nessa estratégia.
Envolvimento comunitário na Estratégia de Saúde da Família: dilemas entre institucionalização e efetiva participação
Authors: Bispo Júnior José Patrício , Martins Poliana Cardoso
Published: January 2013

Este artigo analisa o desempenho dos Conselhos Locais de Saúde enquanto instrumentos da participação social no âmbito da Estratégia de Saúde da Família. Trata-se de pesquisa quali-quantitativa com triangulação de métodos. O campo de estudo foi o município de Vitória da Conquista-BA. Os dados e informações foram obtidos por meio de análise da agenda de compromissos, dos formulários de acompanhamento, das atas das reuniões dos conselhos e por entrevistas semiestruturadas com informantes-chave. Os resultados demonstraram que os conselhos locais de saúde apresentam desempenho limitado, com baixa frequência de realização de reuniões, agenda de compromissos voltada para o próprio conselho e reuniões pautadas nas dificuldades de acesso aos serviços de saúde. Os baixos níveis de mobilização social e envolvimento comunitário são o principal entrave para o bom desempenho desses fóruns. São apontados problemas sobre representatividade dos conselheiros, desmotivação em participar de atividades voluntárias e sentimento de despreparo em decorrência das fragilidades da formação e capacitação. Conclui-se que a institucionalização dos conselhos locais não é condição suficiente para promover a participação comunitária. São sugeridas algumas iniciativas com potencial de promover a mobilização social e despertar as comunidades para a importância da participação e do envolvimento coletivo.
Práticas intersetoriais nas políticas públicas de promoção de saúde
Authors: Azevedo Elaine de , Pelicioni Maria Cecília Focesi , Westphal Marcia Faria
Published: January 2013

Esta revisão analisa algumas políticas públicas estabelecidas entre 2006 e 2010 que dialogam com as diretrizes da Promoção da Saúde, de modo a investigar como a intersetorialidade perpassa suas ações. A intersetorialidade tem o potencial de revitalizar tais políticas, estimulando ações promotoras da saúde que contemplem os complexos condicionantes do processo saúde-doença. Entretanto, evidenciam-se alguns problemas para atingir esse desafio. Destacam-se o despreparo político e técnico de gestores e profissionais da saúde para assumir ações intersetoriais e questões de ordem administrativa que dificultam a execução integrada de ações. Tal despreparo leva, entre outros danos, à falta de reconhecimento de alguns dos temas das políticas como questões legítimas de Saúde Coletiva. Além disso, permanecem em muitas das agendas das políticas, decisões centralizadas que impedem a participação da comunidade e o surgimento de problemas ajustados às realidades locais, cujas soluções exigem intervenções intersetoriais e criativas. Assim, torna-se essencial fomentar um efetivo processo educativo interdisciplinar que forme profissionais da saúde com visão intersetorial em sintonia com as diretrizes das políticas públicas de promoção da saúde. Também é importante valorizar a dimensão territorial e as redes sociais, potencializando processos participativos que ampliem a perspectiva intersetorial dessas políticas, bem como estimular a ativação do sujeito nos processos decisórios.
"Foi normal, não foi forçado!" versus "Fui abusada sexualmente": uma interpretação dos discursos de agressores sexuais, das suas vítimas e de testemunhas

Os crimes sexuais contra crianças e adolescentes são uma forma de violência física que constitui uma preocupação no campo da Saúde Pública. Compreender estes crimes torna-se crucial para se poder intervir na sua prevenção e fundamentar o seu conhecimento para as políticas de saúde. Oartigo analisa as versões do crime sexual, comparando o discurso dos agressores com os depoimentos das vítimas e dos familiares registados em documento judicial. Estudo de natureza qualitativa, utilizando como técnicas de formação do corpus da pesquisa a entrevista individual com réus condenados ao regime de perda de liberdade e a análise documental das sentenças dos agressores sexuais de crianças e adolescentes. A reconstrução do delito sexual por parte dos reclusos, das vítimas e das testemunhas difere muito. Alguns dos agressores admitem o ato sexual criminoso, mas suas justificativas vão no sentido de eximir-se da responsabilidade alegando o consentimento da vítima; outros consideram seu crime uma acusação mentirosa elaborada por terceiros com o propósito de prejudicá-lo. As crenças partilhadas entre eles fazem com que minimizem seus comportamentos delituosos, declarando que o abuso sexual não tenha sido forçado, ou realizado mediante ameaças, nem traga sequelas físicas e psicológicas às vítimas. Os argumentos apresentados frequentemente pelos agressores expõem uma troca de papéis, passando do lugar de agressor ao da vítima. Esses agressores igualmente não reconhecem o fato de as vítimas ficarem com sequelas resultantes da violência sexual que poderão colocar seu futuro em causa.
Doença mental e periculosidade criminal na psiquiatria contemporânea: estratégias discursivas e modelos etiológicos
Authors: Mitjavila Myriam Raquel , Mathes Priscilla Gomes
Published: January 2013

O artigo analisa algumas dimensões socioculturais do campo semântico e dos modos de estruturação dos discursos da psiquiatria forense em torno da periculosidade criminal e de suas conexões com a saúde mental. A partir dos resultados de uma pesquisa baseada na análise de conteúdo de uma amostra de manuais e livros de psiquiatria forense, examinaram-se alguns significados e formas de enunciação da noção de periculosidade criminal, bem como as principais estratégias interpretativas que organizam os modelos etiológicos da criminalidade predominantes nessa área.
A reforma psiquiátrica e seus críticos: considerações sobre a noção de doença mental e seus efeitos assistenciais
Authors: Gama Jairo Roberto de Almeida
Published: January 2013

O objetivo deste trabalho foi discutir as críticas que atualmente são dirigidas ao atual modelo de transformação da assistência psiquiátrica brasileira, exemplificadas nas "Diretrizes para um Modelo de Assistência Integral em Saúde Mental no Brasil" em 2006. Verificamos que existem nesse trabalho pressupostos teóricos sobre a doença mental, a terapêutica e a disciplina psiquiátrica que não estão explicitados e que se baseiam em concepções científicas reducionistas do fenômeno mental. Esses pressupostos apontam para projetos de assistência em saúde mental diversos. Como instrumentos de análise, utilizamos os trabalhos de Georges Canguilhem e do pragmatismo linguístico, além de vários autores críticos à abordagem neurocientífica reducionista. Ao final, propomos uma abordagem científica pragmática e uma perspectiva clínica pluralista.
Como nossos pais? Gerações, sexualidade masculina e autocuidado

Published: January 2013

O presente trabalho tem como objetivo analisar a relação entre os sentidos atribuídos por homens, de dois intervalos geracionais diferentes, à sexualidade masculina e ao cuidar de si. Buscou-se identificar se houve mudança no posicionamento desses homens em relação aos cuidados em saúde e se esta mudança é influenciada por aspectos geracionais. O estudo ancora-se nos marcos conceituais teóricos: geração e roteiro sexual. O desenho metodológico é de análise de narrativas. As fontes analisadas são parte do acervo de duas pesquisas realizadas na cidade do Rio de Janeiro com homens com ensino superior e universitários, que tiveram iniciação sexual nos anos 1970 e 1990, respectivamente. Os resultados mostram que os homens estudados se acham confrontados com a inadequação da construção social do masculino e as novas demandas femininas, buscando um novo modelo. Observaram-se permanências e rupturas de padrões hegemônicos da masculinidade, o que está relacionado com a forma como o homem cuida de si.
