Abstract: Introduction: Lack of information continues to lead the professionals of various areas to contribute to environment degradation, and Dentistry is a potential source of contamination through chemical residues resulting from radiographic procedures. Objective: To evaluate the management of residues resulting from radiographic processing in dental radiology clinics and dental offices in S o Luís – MA, Brazil. Material and methods: A semi-structured questionnaire was prepared with the aim of characterizing the behavior of professionals and their procedures for discarding the processing solutions (developer, fixer, and water) and radiographic packing materials. A sample of 100 individuals represented 7.8% of the total number of 1,281 dentists in the city of S o Luís. Results: A total of 92% of the participants believed that radiographic effluents could cause damage to the environment. Concerning to the fixer discarding, 43% affirmed that they threw the solution directly through the sink, 36% diluted the fixer in water and threw it into the sink, 14% used a specialized company to discard it and 7% used other means. The developer was discarded as follows: 42% threw it down the sink, 36% diluted it in water before throwing it into the sink, 13% used a specialized company to discard it and 9% used other ways. Considering to the discarding of the packing of the radiographic films, 51% threw them into the trash and 49% used a specialized disposal company. Conclusion: Large portions of dentists do not discard radiographic processing residues and films correctly.

Bernardo Matos da Cunha,Licia Maria Henrique da Mota,Leopoldo Luiz dos Santos-Neto
International Journal of Rheumatology , 2012, DOI: 10.1155/2012/369565
Abstract: Introduction. International guidelines recommend interruption of anti-TNF medications in the perioperative period, but there are no randomized trials to support such recommendation. Objectives. To study literature evidence assessing the risk of surgical site infections in orthopedic surgery patients with RA using anti-TNF drugs, compared to untreated patients or those using conventional DMARD. Methods. Systematic review of cohort studies is concerning surgical site infections in orthopedic procedures in patients with RA. Results. Three studies were selected. Only one was considered of high-quality, albeit with low statistical power. The review resulted in inconclusive data, since the best quality study showed no significant differences between groups, while others showed increased risk of infections in patients using anti-TNF medications. Conclusion. It is unclear whether patients with RA using anti-TNF medications are at increased risk of surgical site infections. Randomized controlled trials or new high quality observational studies are needed to clarify the issue. 1. Introduction Rheumatoid arthritis (RA) affects between 0.2 and 1% of brazilian population [1]. Twenty-five percent of RA patients undergo some surgery for the treatment of orthopedic sequelae after 22 years of followup [2]. Currently, most patients with RA are in use of conventional modifying disease activity drugs (DMARD), and some of them are on antagonists of tumor necrosis factor (anti-TNF) medications [3, 4]. Anti-TNF drugs have been used to treat patients with RA who do not get to remission with one or more conventional DMARD. Systematic reviews have shown no increased risk of bacterial infections after treatment with such drugs [5, 6]. There is no consensus in the literature on the use of immunosuppressive drugs in the perioperative period in orthopedic surgery since there are few studies on the topic. A randomized clinical trial showed no increased perioperative infections in patients on methotrexate [7]. There are no clinical trials assessing treatment with anti-TNF medications in this context so far. The guidelines of the American College of Rheumatology (ACR), British Society of Rheumatology, and Japan College of Rheumatology recommend the suspension of anti-TNF medications in the perioperative period [8–10], but this might lead to worsening of disease activity, which could affect the postoperative rehabilitation. In observational studies of patients undergoing hip and knee arthroplasties, several independent risk factors for surgical site infection were found, including RA

Abstract: ResumoA Reserva Florestal Adolpho Ducke (RFAD) é um fragmento de 10.000 hectares em conflito geográfico com a cidade de Manaus. O conhecimento da diversidade dos Ephemeroptera na RFAD é fundamental uma vez que estes organismos s o elementos biológicos importantes; como importante fonte de alimento e, por seu potencial como indicadores das perturba es antropogênicas. Neste estudo teve-se como objetivo o levantamento da fauna de Leptophlebiidae (Ephemeroptera) das duas bacias hidrográficas, comparando a diversidade entre as bacias e entre os períodos seco e chuvoso. Coletou-se em 38 pontos dos igarapés das bacias Leste (Ipiranga, Uberê e Tinga) e a Oeste (Acará e Bolívia) da RFAD com rede entomológica aquática (rapiché). Para verificar diferen as na riqueza das duas bacias e, comparar a riqueza nos períodos seco e chuvoso foi feito o índice de Riqueza de Jackknife. Foram obtidas 804 larvas de Leptophlebiidae sendo identificados 368 indivíduos e reconhecidos sete gêneros: Hagenulopsis Ulmer (35%; n=128); Thraulodes Ulmer (34%; n=124); Farrodes Peters (13%; n=48); Miroculis Edmunds Jr (12%; n=45); Hydrosmilodon Flowers & Dominguez (5%; n=19); Hermanella Needham & Murphy (0.8%; n=3), Microphlebia Savage & Peters (n=1). Este representa o primeiro registro de Hydrosmilodon, Hermanella e Microphlebia para a RFAD. Na compara o entre as bacias Leste e Oeste, o índice de Riqueza de Jackknife n o indicou diferen a significativa na riqueza de gêneros. Hermanella e Hydrosmilodon n o ocorreram na bacia Oeste e, Microphlebia n o ocorreu na bacia Leste, no entanto estas ausências n o representam diferen a significativa na riqueza taxon mica das bacias. A compara o na riqueza de espécie de Leptophlebiidae considerando o período seco e chuvoso revelou uma diferen a significativa entre os períodos. Cerca de 68% dos indivíduos foram coletados no período seco provavelmente porque neste período a água fica restrita ao canal do igarapé fornecendo substrato estável (vegeta o marginal e folhi o) para a manuten o da fauna. No período chuvoso o substrato é carreado pelas enxurradas n o sendo possível manuten o da fauna.Diversity of Larve Leptophlebiidae (Insecta: Ephemeroptera) of the Adolpho Ducke Forest Reserve, Manaus, AM.. The Adolpho Ducke Forest Reserve (ADRF) is a fragment of 10.000 hectares in geographic conflict with the city of Manaus. The knowledge of the diversity of Ephemeroptera in the ADRF is essencial because these organisms are biological important elements as food source and for its potential as indicative of the human disturbances.

Abstract: The treatments of choice in Alzheimer's disease (AD) are cholinesterase inhibitors and NMDA-receptor antagonists, although doubts remain about the therapeutic effectiveness of these drugs. Herbal medicine products have been used in the treatment of Behavioral and Psychological Symptoms of Dementia (BPSD) but with various responses. The objective of this article was to review evidences from controlled studies in order to determine whether herbs can be useful in the treatment of cognitive disorders in the elderly. Randomized controlled studies assessing AD in individuals older than 65 years were identified through searches of MEDLINE, LILACS, Cochrane Library, dissertation Abstract (USA), ADEAR (Alzheimer's Disease Clinical Trials Database), National Research Register, Current Controlled trials, Centerwatch Trials Database and PsychINFO Journal Articles. The search combined the terms Alzheimer disease, dementia, cognition disorders, Herbal, Phytotherapy. The crossover results were evaluated by the Jadad's measurement scale. The systematic review identified two herbs and herbal formulations with therapeutic effects for the treatment of AD: Melissa officinalis, Salvia officinalis and Yi-Gan San and BDW (Ba Wei Di Huang Wan). Ginkgo biloba was identified in a meta-analysis study. All five herbs are useful for cognitive impairment of AD. M. officinalis and Yi-Gan San are also useful in agitation, for they have sedative effects. These herbs and formulations have demonstrated good therapeutic effectiveness but these results need to be compared with those of traditional drugs. Further large multicenter studies should be conducted in order to test the cost-effectiveness of these herbs for AD and the impact in the control of cognitive deterioration.

Abstract: the article had the purpose of commenting on studies on polypharmacy in the elderly, focusing on diagnosis and control. polypharmacy is defined as the use of a number of medications at the same time and the use of additional drugs to correct drug adverse effects. the fact that the elderly take more medications for the treatment of several diseases makes them more susceptible to the occurrence of adverse reactions. prophylactic actions such as balanced prescriptions are vital to reduce the incidence of these reactions and prevent longer hospital stay, increased costs and aggravation of the elderly health condition.
