Bone quality and quantity are important factors with regard to the survival rate of dental implants. The aim of this study was to conduct a systematic review of dental implants inserted in low-density bone and to determine the survival rate of dental implants with surface treatments over time. A systematic review of the literature was undertaken by two independent individuals; the Medline/PubMed database was searched for the period July 1975 to March 2013. Relevant reports on bone quality and osseointegration of dental implants were selected. The search retrieved 1018 references, and after inclusion and exclusion criteria were applied, 19 studies were selected for review. A total of 3937 patients, who had received a total of 12,465 dental implants, were analyzed. The survival rates of dental implants according to the bone density were: type I, 97.6%; type II, 96.2%; type III, 96.5%; and type IV, 88.8%. The survival rate of treated surface implants inserted in low-density bone was higher (97.1%) than that of machined surface implants (91.6%). Surface-treated dental implants inserted in low-density bone have a high survival rate and may be indicated for oral rehabilitation. However, more randomized studies are required to better evaluate this issue.

Objective To evaluate the prevalence and risk factors of non-alcoholic fatty liver disease (NAFLD) in postmenopausal women.Methods A cross-sectional study was carried involving 188 women (age >= 45 years and amenorrhea >= 12 months) attending the outpatient unit in south-eastern Brazil. Exclusion criteria were liver disease (hepatitis B and C, cholestatic disease, liver insufficiency), use of drugs that affect liver metabolism; alcoholics; AIDS or cancer history; and morbid obesity. NAFLD was diagnosed by abdominal ultrasound. Clinical, anthropometric (body mass index, waist circumference) and biochemical variables were measured.Results Of the 188 women, 73 (38.8%) had NAFLD. Blood pressure, waist circumference, body mass index, LDL cholesterol, triglycerides and glucose were significantly higher in NAFLD patients when compared with women without NAFLD (control group) (p < 0.05). HOMA-IR values indicated insulin resistance only in the NAFLD group (6.1 +/- 4.6 vs. 2.4 +/- 1.4 in control group, p < 0.05). Metabolic syndrome was detected in 93.1% of the women affected by NAFLD, and 46.1% of the control group (p < 0.05). In multivariate analysis, adjusted for age and weight, the variables considered at risk for the development of NAFLD, were: high waist circumference (odds ratio (OR) 1.07, 95% confidence interval (CI) 1.01-1.13), insulin resistance (OR 3.81, 95% CI 2.01-7.13), and presence of metabolic syndrome (OR 8.68, 95% CI 3.3-24.1).Conclusion NAFLD showed a high prevalence among postmenopausal women. The presence of metabolic syndrome, abdominal obesity and IR were indicators of risk for the development of NAFLD.

Uma das diretrizes da Portaria nº3916 do Ministério da Saúde (MS) é a Relação Nacional de Medicamentos Essenciais (RENAME). A prescrição de medicamentos dentro do Sistema Único de Saúde (SUS) deve ser feita utilizando medicamentos listados nessa relação. O medicamento genérico, criado e regulamentado pela Lei nº9787, é prioridade da Política Nacional de Medicamentos do MS. De acordo com esta lei, “as prescrições médicas e odontológicas de medicamentos, no âmbito do Sistema Único de Saúde – SUS adotarão obrigatoriamente a Denominação Comum Brasileira (DCB)”. A Portaria 344/98 MS, que regulamenta o controle dos medicamentos sujeitos a controle especial, determina os itens que devem estar presentes nas notificações. Neste trabalho, 1177 notificações retidas em uma drogaria de Araraquara durante o período de junho de 2008 a outubro de 2010 foram separadas e analisadas quanto: a) à utilização da DCB; b) quanto à utilização de medicamentos listados na RENAME; e c) quanto à adequação a Portaria 344/98 MS. Também foi avaliado o conhecimento dos prescritores quanto às leis vigentes através da aplicação de um questionário semiestruturado. Entre as 1177 notificações analisadas, 779 (66,18%) foram prescritas utilizando o nome comercial e 398 (33,82%) foram prescritas utilizando a DCB. Analisando as 399 notificações vindas do SUS, 188 (47,11%) adotaram os medicamentos da RENAME. Foram encontrados 319 problemas com as notificações de acordo com a Portaria 344/98 MS, os quais foram: 22 (1,86%) notificações com algum erro na identificação do emitente e/ou assinatura do prescritor; 3 (0,25%) notificações com algum erro na identificação do usuário; 294 (24,97%) notificações com preenchimento confuso nos itens como nome do medicamento ou substância, dosagem ou concentração, forma farmacêutica , quantidade e posologia; e 465 (39,50%)...

Neste artigo, apresentaremos um estudo da tradução da obra Inferno da autora Patrícia Melo, com o título Inferno, por Clifford Landers. Buscamos refletir sobre como são projetados no exterior uma visão da realidade violenta de grandes centros urbanos brasileiros e sobre o quanto o tradutor conseguiu resgatar da nossa sociedade no texto traduzido. Partimos do pressuposto de que o tradutor, consciente ou inconscientemente, usa recursos durante o processo de mediação entre o texto de partida e o texto de chegada, que tornam a leitura da obra traduzida mais fácil. Baker (1996) propõe a investigação de tipos de comportamento linguístico característicos de textos traduzidos. O objetivo desse trabalho é identificar aspectos de normalização presentes na tradução. Para a investigação, recorremos aos Estudos da Tradução Baseados em Corpus (Baker, 1993, 1996; Camargo, 2005, 2007), à Linguística de Corpus (Berber Sardinha, 2004) e aos estudos sobre normalização de Scott (1998). Pode-se observar a ocorrência de mudança de registro de linguagem, omissões, adições, diferenças no comprimento das sentenças e relacionadas a imprecisões de expressões. Espera-se que o presente trabalho possa contribuir para uma maior conscientização das tendências apresentadas pelos tradutores, e para apresentar as possibilidades oferecidas pela intersecção dos Estudos da Tradução Baseados em Corpus e da Linguística de Corpus.

The study aimed to assess the degree of dental crowding correction on the lower anterior region of patients treated with T4k functional appliance using Little’s irregularity index. Twenty caucasian patients of both gender (10 female and 10 male) were selected. They featured malocclusion Class I and II in mixed dentition, with chronological age between 5.7 and 11 years. The treatment lasted from 1 year and 11 months up to 3 years and 11 months. Lower anterior crowding was measured using Little’s irregularity index. Measurements were obtained on study models achieved before and after functional orthopedic therapy, using a digital caliper in millimeters and placed parallel to the occlusal plane. Overjet and overbite measurements were also performed using a caliper. Results demonstrated that the therapy provided significant decrease in overjet (average = 1.55 mm) and also in the irregularity index (average = 1.23 mm). There was a nonsignificant raise in overbite. There was no relation between the studied variables and the treatment period or even with the patient’s age in the beginning of the therapy. The treatment with T4k resulted on reduction and improvement of dental crowding.

Objectives: To evaluate the anti-erosive potential of solutions containing sodium fluoride (NaF, 225 ppm F) and different film-forming agents.Methods: In Phase 1, hydroxyapatite crystals were pre-treated with solutions containing NaF (F), linear sodium polyphosphate (LPP), sodium pyrophosphate tetrabasic (PP), sodium tripolyphosphate (STP), sodium caseinate (SC), bovine serum albumin (BSA), stannous chloride (Sn) and some combinations thereof. Deionized water was the control (C). The pH-stat method was used to evaluate hydroxyapatite dissolution. In Phase 2, the most effective solutions were tested in two independent experiments. Both consisted of an erosion-remineralization cycling model using enamel and dentine specimens with three solution treatments per day. In Phase 2a, the challenge was performed with 0.3% citric acid (pH = 3.8). In Phase 2b, 1% citric acid (pH = 2.4) was used. Hard tissue surface loss was determined profilometrically. Data were analyzed with two-way ANOVA and Tukey tests.Results: In Phase 1, F, LPP, Sn and some of their combinations caused the greatest reduction in hydroxyapatite dissolution. In Phase 2a, C showed the highest enamel loss, followed by LPP. There were no differences between all other groups. In Phase 2b: (F + LPP + Sn) < (F + LPP) = (F + Sn) < (F) = (LPP + Sn) < (LPP) < (Sn) < C. For dentine, in both experiments, only the fluoride-containing groups showed lower surface loss than C, except for LPP + Sn in 2a.Conclusions: F, Sn, LPP reduced enamel erosion, this effect was enhanced by their combination under highly erosive conditions. For dentine, the F-containing groups showed similar protective effect.Clinical significance: The addition of LPP and/or Sn can improve the fluoride solution protection against erosion of enamel but not of dentine.

Background and aims Estrogen deficiency results in increased bone turnover and can lead to osteoporosis. Hormone replacement therapy (HRT) seems to be the most effective means of reducing bone loss and fractures. However, the effects of the period of HRT onset on bone tissue require further elucidation. This study aimed to evaluate the effects of different periods of HRT onset on the trabecular bone of ovariectomized rats.Methods Seventy-five ovariectomized Wistar rats were divided into five groups according to the onset of treatment. Each group was subdivided into experimental (E; n = 10) and control (C; n = 5), according to treatment with 17-beta-estradiol or vehicle alone (soybean oil), respectively, administered subcutaneously. The first group received treatment immediately post-surgery, while treatment in the remaining groups was initiated 1, 2, 3 and 4 weeks post-surgery. Euthanasia occurred at 9 weeks post-surgery. The left tibias were removed and prepared for histomorphometric analyses. The histomorphometric results were statistically analyzed by the Student's t test (p < 0.05).Results The percentage of trabecular bone was significantly greater in the first (p = 0.002) and second (p = 0.039) experimental subgroups compared with the control for the same period. In the experimental subgroups, the percentage of trabecular bone decreased according to the delay in HRT onset and was statistically significant (t = 3.367; p = 0.0023).Conclusion These findings indicate an increase in trabecular bone loss in tibia at 9 weeks post-ovariectomy. The period of HRT/E onset is important for preventing bone loss; however, despite its preventive effects, HRT/E does not restore lost bone.
