Técnica radiográfica extra-oral, uma alternativa possível para o tratamento endodôntico: relato de caso clínico

A realização de tomadas radiográficas é de extrema importância durante o tratamento endodôntico. A radiografia periapical intra-oral é a mais utilizada, tanto pela simplicidade de sua técnica, quanto pelo custo reduzido. Entretanto, alguns pacientes possuem uma intolerância ao filme no interior da cavidade bucal, o que inviabilizaria em alguns casos, o diagnóstico e o posterior tratamento. O objetivo do presente estudo visa descrever através de um caso clínico, a técnica de Newman e Friedman, caracterizada pela presença do filme radiográfico posicionado fora da cavidade oral. Apesar de pouco descrita na literatura, em determinados casos, pode apresentar resultados satisfatórios

Trauma in Primary Teeth at a Specialized Service Center: Retrospective Cohort

Objective: To evaluate the factors associated with the occurrence of dental trauma in children up to six years of age and describe the results of clinical follow-up and possible sequelae. Material and Methods: A retrospective study was carried out with data collected from the dental records of 96 pediatric patients up to 6 years old with traumatized primary teeth who sought care from the. Pediatric Dental Trauma project of a private university in the city of Rio de Janeiro from July 2014 to July 2017, and who had clinical and radiographic follow-up for up to three months as of their initial visit. Results: 96 children (58.3% boys and 41.7% girls) included who presented 166 traumatized primary teeth. Intrusion was the most observed type of trauma and in 45.8% of cases, the care occurred one-week post trauma. The maxillary central incisors were the most affected teeth (97.6%). The prognosis of the dental elements with more than 3 months of follow-up was considered favorable, and 59.6% of the teeth did not present any clinical or radiological sequelae. Oral hygiene instruction and monitoring were the most common approaches. Conclusion: The prevalence of dental trauma in the present study was high and occurred mainly in domestic settings. The upper central incisors were the teeth that suffered the most injuries. The presence of patients at follow-up visits was an important factor for the positive result in most cases

Recall Rates of Patients in Endodontic Treatments: A Critical Review

The number of patients that return for recall appointments has great importance to validate endodontic treatment outcomes. The purpose of this review was to investigate the rate of return on recall and the main factors that influence this rate of return. A literature review was performed in the PubMed database for the years from 1978 to 2017, using the following keywords: recall rate, endodontic treatment, endodontic retreatment, apical surgery. The inclusion criteria were: prospective studies in English, and in vivo research with humans, which included patient return rates. A total of 35 studies that fulfilled the established criteria were selected. The percentage of patients who returned on recall was 56%. More female patients (60%) attended the recall appointments than male (40%). The three main reasons for not returning were: patients did not observe the follow-up appointment (490), not returning due to a lack of interest (99) and   changing their address (222). The age of the patients attending the appointments varied from 28.6 to 62 years old, with the highest percentage of patients that returned ranging from 40 to 52.5 years old. According to the literature the optimal rate of return for follow-up treatment should be greater than 80%, for the validity of the research. However, the reality presented in the studies is far from ideal. Many studies do not even mention these rates of return in their methodologies or in their results, which may mask the true treatment success rates.Keywords: Endodontic Recall; Follow-up; Recal

High incidence of acquiring methicillin-resistant <i>Staphylococcus aureus</i> in Brazilian children with Atopic Dermatitis and associated risk factors

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) colonization in Atopic Dermatitis (AD) patients can contribute to worsening their clinical condition. OBJECTIVE: A cohort study was carried out to determine the incidence of MRSA acquisition and its risk factors in AD children. METHODS: Patients with AD (2 months-14 years old) were followed up for about 1 year at a reference center for AD treatment in Rio de Janeiro, Brazil, from September 2011 to February 2014. Nasal swabs from patients and contacts were collected every 2 months. The SCORAD system assessed the severity of the AD. S. aureus isolates were evaluated to determine the methicillin resistance and the clonal lineages. RESULTS: Among 117 AD patients, 97 (82.9%) were already colonized with S. aureus and 26 (22.2%) had MRSA at the first evaluation. The incidence of MRSA acquisition in the cohort study was 27.47% (n = 25). The SCORAD assessments were: mild (46.15%), moderate (37.36%) or severe (16.48%). Risk factors were: colonized MRSA contacts (HR = 2.27; 95% CI: 1.16-7.54), use of cyclosporine (HR = 5.84; 95% CI: 1.70-19.98), moderate or severe AD (HR = 3.26; 95% CI: 1.13-9.37). Protective factors were: availability of running water (HR = 0.21; 95% CI: 0.049-0.96) and use of antihistamines (HR = 0.21; 95% IC: 0.64-0.75). MRSA isolates carried the SCCmec type IV and most of them were typed as USA800/ST5. CONCLUSIONS: The high incidence of MRSA acquisition found among AD patients and the risk factors associated show that an effective surveillance of MRSA colonization in these patients is needed

O sistema hidrológico do Taim

O Sistema Hidrológico do Taim é um sistema límnico complexo composto de banhados e lagoas interconectadas. Esse sistema tem associado uma Unidade de Conservação Federal, a Estação Ecológica do Taim, e a cultura de arroz, a qual usa água do sistema para irrigação. A simultânea conservação do sistema com o uso da água é um desafio para a região, uma vez que ambos são dependentes do manejo da água. A gestão do sistema depende do entendimento de padrões e regimes. A água, na forma de hidroperíodo e hidrodinâmica, é a função de força dominante na formação, no estado e na evolução desse sistema hidrológico. Conhecer a assinatura hidrológica do sistema é fundamental para o entendimento da sua estrutura e do seu funcionamento. Essa assinatura influencia as comunidades biológicas e/ou espécies indicadoras. Padrões de comunidades acompanhadas no tempo permitem verificar a dinâmica oscilatória e a eventual mudança de regime em função de estressores antrópicos ou naturais, tanto na observação direta como por modelagem ecológica. O entendimento dos padrões espaciais e temporais no Sistema Hidrológico do Taim é a base para a proposta de uso e conservação simultânea.The Taim Hydrological System is a complex limnetic system composed of interconnected wetlands and lakes. This system has an associated federal conservation unit, the Taim Ecological Station, and rice cultivation, which uses water from the system for irrigation. Conservation of the system concomitantly with the use of its water is a challenge, since both functions depend on water management. The system management depends on understanding patterns and regimes. The hydroperiod and hydrodynamics are the dominant driving forces in the formation, evolution and current state of this hydrological system, and influence the biological communities and indicator species. Following the community patterns over time allows tracking of the oscillatory dynamics and possible regime change due to anthropogenic or natural stressors, both as direct observation or by ecological modeling. Understanding the spatial and temporal patterns in the Taim Hydrological System is the basis for the most efficient simultaneous use and conservation

ATLANTIC BIRD TRAITS: a data set of bird morphological traits from the Atlantic forests of South America

Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra- and interspecies spatial morphological variation. Here, we present the ATLANTIC BIRD TRAITS, a data set that includes measurements of up to 44 morphological traits in 67,197 bird records from 2,790 populations distributed throughout the Atlantic forests of South America. This data set comprises information, compiled over two centuries (1820–2018), for 711 bird species, which represent 80% of all known bird diversity in the Atlantic Forest. Among the most commonly reported traits are sex (n = 65,717), age (n = 63,852), body mass (n = 58,768), flight molt presence (n = 44,941), molt presence (n = 44,847), body molt presence (n = 44,606), tail length (n = 43,005), reproductive stage (n = 42,588), bill length (n = 37,409), body length (n = 28,394), right wing length (n = 21,950), tarsus length (n = 20,342), and wing length (n = 18,071). The most frequently recorded species are Chiroxiphia caudata (n = 1,837), Turdus albicollis (n = 1,658), Trichothraupis melanops (n = 1,468), Turdus leucomelas (n = 1,436), and Basileuterus culicivorus (n = 1,384). The species recorded in the greatest number of sampling localities are Basileuterus culicivorus (n = 243), Trichothraupis melanops (n = 242), Chiroxiphia caudata (n = 210), Platyrinchus mystaceus (n = 208), and Turdus rufiventris (n = 191). ATLANTIC BIRD TRAITS (ABT) is the most comprehensive data set on measurements of bird morphological traits found in a biodiversity hotspot; it provides data for basic and applied research at multiple scales, from individual to community, and from the local to the macroecological perspectives.
