RESUMO
BACKGROUND: The most common current hearing protection devices (HPDs) on the market include earplugs and earmuffs. A variety of materials can be used to manufacture these devices, and each offers a level of noise attenuation that is informed by the manufacturer although it does not always correspond to the attenuation observed in real-world use. OBJECTIVE: To evaluate the noise attenuation of HPDs available to workers exposed to noise. METHODS: The most relevant studies originally published in English, Portuguese, or Spanish that investigated the noise attenuation effectiveness of HPDs used by workers exposed to noise were analyzed. The following electronic databases were searched by 2 independent reviewers for studies published from 1999 to 2019: MEDLINE (PubMed), Scopus, Web of Science, EMBASE, Cochrane Library (OVID), ProQuest, and BVS-Bireme. Different combinations of the following search terms (MeSH terms) were used for all databases: "Hearing Loss, Noise-Induced", "Ear Protective Devices" (Efficacy OR Effectiveness)", "Noise, Occupational". RESULTS: The search strategy yielded a total of 326 potentially relevant studies. After the removal of duplicates, 156 remained for the screening of titles and abstracts. After reviewing titles and abstracts, 46 studies were selected for full-text reading. Of these, six were included in this systematic review. CONCLUSION: Hearing protection devices reduced the noise exposure and were effective in all included studies in different countries, types of activity, and sound pressure exposure.

Introduction: Breast cancer is the most common malignant tumor in the world, with the exception of cases of non-melanoma skin cancer. In Brazil, more than 56,000 cases were estimated for 2016. The expected mortality rate remains high because of late diagnosis. Nowadays, conservative surgery is the gold standard treatment. Objective: To evaluate the locoregional recurrence of conservative surgery practiced at the Ceará Institute of Cancer, between 2002 and 2012. Method: A cross sectional study with a descriptive approach using secondary data obtained from the medical records of patients with breast cancer operated at the Ceará Institute of Cancer. Results: The study population consisted of 360 patients. Invasive ductal carcinoma was the most common type (72.8%), followed by ductal carcinoma in situ (16.4%) and invasive lobular carcinoma (4.7%). The other histological types represent 6.4% (cribriform, 0.5%, medullary, 0.6%, micro invasive, 0.3%, mucinous, 1.1%, papillary, 3.1% 8%; and tubular, 0.8%). In the sample, 25 patients had some type of recurrence: 13/360 (3.6%), local or locoregional; and 12/360 (3.3%), distant recurrence. Conclusion: From the data analysis, we can conclude that the conservative surgery practiced at the Ceará Institute of Cancer showed data on recurrence compatible with the international literature
Introdução: O câncer de mama é o tumor maligno que mais acomete mulheres em todo o mundo, excetuando-se os casos de pele não melanoma. No Brasil, estimavam-se mais de 56.000 casos para 2016. A mortalidade esperada ainda é alta devido ao diagnóstico tardio. Na atualidade, a cirurgia conservadora é o padrão-ouro. Objetivo: Avaliar a recidiva locorregional da cirurgia conservadora praticada no Instituto do Câncer do Ceará, no período entre 2002 a 2012. Método: Estudo transversal e descritivo, utilizando dados secundários obtidos nos prontuários médicos de pacientes com câncer de mama operadas no Instituto do Câncer do Ceará. Resultados: A população em estudo foi de 360 pacientes. O carcinoma ductal invasivo foi o tipo mais comum (72,8%), seguido do carcinoma ductal in situ (16,4%) e do carcinoma lobular invasivo (4,7%). Os outros tipos histológicos representam 6,4% (cribiforme, 0,5%; medular, 0,6%; microinvasor, 0,3%; mucinosos, 1,1%; papilífero, 3,1%; e tubular, 0,8%). Na amostra, 25 pacientes tiveram algum tipo de recidiva: 13/360 (3,6%), local ou locorregional; e 12/360 (3,3%), recidiva a distância. Conclusão: Da análise dos dados, podemos concluir que a cirurgia conservadora praticada no Instituto do Câncer do Ceará tem dados de recorrência compatíveis com a literatura internacional
RESUMO
Objective: This in vitro study aimed to determine and compare the dimensional accuracy of open and closed-tray impression techniques for implantsupported prosthesis. Material and Methods: On a edentulous master model, four external hexagonal implants were parallelly installed and associated with four multi unit coping transfers and four multi unit rotational caps. A master superstructure was constructed and splinted all implants (control group). Five customized trays were constructed to perform ten open (n=5) and closed-tray (n=5) impressions. The obtained models were submitted to the dimensional analysis on three points in the center of the labial face of each implant (A, B, C, and D) with the aid of Stereoscopic Magnifying Glass with x60 magnification. The vertical misfit between the metallic structure and the implant analogues was measured on each point. The obtained results were submitted to Dixon's normality test and KruskalWallis test for independent samples p < 0.05) with the aid of Bioestat 5.0 software. Results: The means and standard deviation were: open tray technique 24.6474 ± 14.8883 µm; closed-tray technique 26.2257 ± 9.7421 µm; and control group 22.445 ± 7.7106 µm. Conclusion: The accuracy of open and closed-tray impression techniques showed no statistically significant differences and both techniques were effective for implant transfer. (AU)
Objetivos: O presente estudo in vitro objetiva determinar e comparar a precisão dimensional das técnicas de transferência de implantes direta e indireta para próteses implantossuportadas. Material e Métodos: a partir de um modelo mestre mandibular desdentado, foram instalados paralelamente quatro implantes hexágonos externos associados a quatro componentes multi unit e quatro capas multi unit rotacionais. Confeccionou-se uma infraestrutura mestre metálica unindo todos os elementos, considerando o conjunto como grupo controle (GC). Ao todo, fabricaram-se cinco moldeiras individuais para realizar 10 moldagens mediante as técnicas direta e indireta (n= 5), sendo os modelos obtidos submetidos à análise dimensional e estatística. Com uma lupa estereoscópica binocular com ampliação de 60 x, estabeleceram-se três pontos no centro da face vestibular de cada um dos implantes (A, B, C e D) por amostra. Em cada ponto, mensurou-se o desajuste vertical entre a estrutura metálica e os análogos. Os resultados obtidos foram submetidos ao teste de normalidade de Dixon e teste de Kruskal- Wallis para amostras independentes (p< 0,05) com o auxílio do software Bioestat 5.0. Resultados: médias aritméticas e desvio padrão identificados no grupo moldagem direta (24,6474 ± 14,8883 µm) e moldagem indireta (26,2257 ± 9,7421 µm) em comparação com o modelo mestre (22,445 ± 7,7106 µm). Conclusão: Pôde-se concluir que não houve diferenças estatísticas significativas entre as técnicas na precisão da transferência de implantes, sendo ambas igualmente eficientes. (AU)

The objective of this article is to analyze the background of the historiography of psychoanalysis in Rio de Janeiro. Three different phases and approaches are analyzed, based on the viewpoints of different groups of authors. The first group features authors who displayed an early interest in the subject, in the 1920's-1930's. The second refers to psychiatrists/psychoanalysts who worked with mental health institutes and societies between the 1940's and 1970's, while the third perspective comes from the academic/university environment, from the end of the 70's to the present. This distinction was made not only to better define the timeframe of the arrival and dissemination of psychoanalysis in Rio de Janeiro, but also to provide a better understanding of the relation between the specific professional and intellectual interests of each group and the respective historical context.

The aim of this preliminary study was to investigate whether religious practice can modify quality of life (QoL) in BC patients during chemotherapy. QoL and religion practice questionnaire (RPQ) scores were evaluated in a sample of BC patients in different moments. Before chemotherapy initiation, women with lower physical and social functional scores displayed higher RPQ scores. On the other hand, low RPQ patients worsened some QoL scores over time. Body image acceptance was positively correlated with religious practice and specifically praying activity. This preliminary study suggests the importance of religion in coping with cancer chemotherapy.

We report a patient with longstanding Behçet disease who presented sudden onset of headache and facial paresis. The magnetic resonance imaging (MRI) showed a mass in the right thalamus, extending to the lentiform nucleus, subthalamic area, right cerebral peduncle and deep subcortical white matter. Stereotactic brain biopsy disclosed gliosis with no signs of malignancy. The diagnosis of a pseudotumoral form of neuro-Behçet disease was done and she was treated with pulse methylpredinisolone and intravenous cyclophosphamide. After 8 weeks she had improved and a new MRI showed disappearance of the tumor-like lesion. The differential diagnosis, especially with central nervous system tumor is emphasized.

UNLABELLED: There are few papers devoted to geriatric Guillain-Barré (GBS) and many related issues remain unanswered. OBJECTIVE: To describe clinical, electrophysiological and therapeutic features in this age. METHOD: Clinico-epidemiological data and therapy of GBS patients older than 60 years were reviewed. Hughes scores were used to quantify neurological deficit and define outcome. RESULTS: Among 18 patients (mean age 64.8 years), 9 had evident prodrome and 80% noticed initially sensory-motor deficit. Demyelinating GBS was found in 8 and axonal in 6 subjects. There was one Miller-Fisher and 3 unclassified cases. Plasmapheresis (PFX) was single therapy in 12 patients and intravenous immunoglobulin (IVIg) in 2. Disability scores just before therapy were similar in both groups, so as short and long term outcome. CONCLUSION: Axonal GBS seems to be more frequent in the elderly and this may have prognostic implications. PFX and IVIg were suitable options, but complications were noticed with PFX. Prospective studies are needed to better understand and manage GBS in the elderly.
