ABSTRACT

Background: The understanding of how individuals manage their emotional experiences has flourished dramatically over the last decades, including assessing of emotion (dys) regulation. The Difficulties in Emotion Regulation Scale (DERS) is a well-validated and extensively used self-report instrument for emotion regulation problems. Despite the wide use of DERS in both clinical and research settings, its length potentially increases fatigue and frustration in respondents and limits its inclusion in brief research protocols. Consequently, a short-form version of the DERS (DERSSF) was developed, which requires cross-cultural adaptations and the study of its reliability and validity. Objectives: In order to address this issue, this study aimed to analyze the factorial structure and psychometric properties of the Portuguese version of DERS-SF and examine the DERS-SF factor structure invariance between men and women. Methods: The sample comprised 646 participants aged between 18 and 66 years (M = 29.93, SD = 11.71). Results: The correlated six-factor structure of the original version has an acceptable fit, good reliability, and convergent validity. Our results also suggested the invariance of the factor structure of the DERS-SF across genders. Conclusion: The DERS-SF has good psychometric properties, and it may be useful for future research and clinical work to use this six-factor brief version and improve emotion regulation assessment.

ABSTRACT

A psicodinâmica do trabalho se configura como uma das principais correntes da Psicologia do Trabalho e das Clínicas do Trabalho. Foi desenvolvida inicialmente por Christophe Dejours e se disseminou amplamente entre os pesquisadores dessa área, inclusive brasileiros. O objetivo deste artigo é identificar quais as principais discussões sobre a psicodinâmica do trabalho no Brasil, em artigos publicados na base de dados SciELO entre os anos de 2005 e 2015. A metodologia utilizada foi a pesquisa bibliográfica. A análise dos dados permitiu compreender que a psicodinâmica vem se firmando como referencial teórico e suporte teórico-metodológico para os estudos que visam compreender as relações dinâmicas presentes entre a organização do trabalho e os processos de subjetivação dos trabalhadores, contribuindo com o conhecimento sobre o trabalho. Além disso, constatamos que os autores brasileiros estão se destacando como referência sobre a psicodinâmica do trabalho.

ABSTRACT

Introdução: a fístula vesico-uterina é a comunicação menos comum entre sistema geniturinário e reprodutor. É uma complicação rara e representa apenas 4% de todas as fístulas urogenitais. A maioria dos casos ocorre após procedimento obstétrico ou ginecológico, sendo que 83% relacionam-se com cesariana repetida. Se diagnosticada precocemente, a terapia conservadora é uma opção, visto que em até 6 meses a fístula pode ter fechamento espontâneo. Entretanto, o tratamento primário é o reparo cirúrgico, o qual apresenta bons resultados. Método: relato de caso baseado em dados retrospectivos do prontuário médico do paciente e revisão de literatura. Resultado: paciente do sexo feminino submetida a cesariana e evoluiu no pós-operatório com diagnóstico de fístula vesico-uterina. Conclusão: a fístula vesico-uterina, assim como as demais fístulas urogenitais, apresenta boa resposta ao tratamento cirúrgico, sendo que a primeira intervenção é a de maior sucesso, resultando na cura


Introduction: The vesico-uterine fistula is the least common communication between the genitourinary system and the reproductive system. It is a rare complication and accounts for only 4% of all urogenital fistulas. Most cases occur after obstetrical or gynecological procedures, 83% of which are related to repeated cesarean section. If diagnosed early, conservative therapy is an option, since within 6 months the fistula may have spontaneous closure. However, the primary treatment is surgical repair, which has good results. Method: Case report based on retrospective patient medical records and literature review. Results: A female patient submitted to cesarean section and evolved postoperative with a diagnosis of vesico-uterine fistula. Conclusion: Vesico-uterine fistula, as well as other urogenital fistulas, presents a good response to surgical treatment, with the first intervention being the most successful, resulting in cure

ABSTRACT

As abordagens não invasivas apresentam a imensa vantagem de preservação estrutural, que é fundamental para a sobrevivência a longo prazo da peça dentária. No âmbito desses tratamentos, este artigo descreve um caso clínico em que as resinas compostas foram utilizadas para otimização estética não invasiva do sorriso. Neste caso, tal como diversos autores têm demonstrado, as resinas compostas permitiram obter resultado estético satisfatório para a paciente. Além da habilidade clínica, é necessário que a equipe possa fazer diagnóstico, simulações, bem como comunicar ao paciente as possibilidades e vantagens dessas estratégias de tratamento. O facto de abordagens não invasivas serem reversíveis com relativa facilidade permite que não se excluam outras abordagens futuras, o que representa coerência interessante do ponto de vista biológico e estético.


Non-invasive dental treatments allow tissue preservation, which is important for long-term survival of teeth. The authors describe a clinical case where resin composites were used for a non-invasive esthetic optimization of a patient’s smile. In this case, similar to several authors have described, a good esthetic result was achieved. In addition to the clinical skills, it is important for the team to be able to diagnose, make simulations of the result and communicate the patients all the possibilities and advantages of these treatment possibilities. Since these non invasive approaches are easily reversible, it is possible to make other treatment options in the future, making these treatments very feasible from a biologic and esthetic point of view.

ABSTRACT

Control of cross-contamination between dental offices and prosthetic laboratories is of utmost importance to maintain the health of patients and dental office staff. The purpose of this study was to evaluate disinfection protocols, considering antimicrobial effectiveness and damage to the structures of prostheses. Solutions of 1% sodium hypochlorite, 2% chlorhexidine digluconate, 50% vinegar and sodium perborate were evaluated. Specimens were contaminated in vitro with standardized suspensions of Candida albicans, Streptococcus mutans, Escherichia coli, Staphylococcus aureus and Bacillus subtilis spores. Disinfection by immersion for 10 min was performed. Final counts of microorganisms were obtained using the plating method. were statistically compared by Kruskal-Wallis ANOVA and Dunn's test. The surface roughness of 40 specimens was analyzed before and after 10 disinfection cycles, and results were compared statistically using Student's t test. The solution of 50% vinegar was as effective as 1% sodium hypochlorite and 2% chlorhexidine against C. albicans, E. coli and S. mutans. The sodium perborate solution showed the lowest antimicrobial effectiveness. Superficial roughness increased after cycles in 1% sodium hypochlorite [p = 0.02]. Solutions of 1% sodium hypochlorite, 2% chlorhexidine and 50% vinegar were effective for the disinfection of heat-polymerized acrylic specimens. Sodium hypochlorite increased the superficial roughness

ABSTRACT

Ozone has been used as an alternative method for the decontamination of water, food, equipment and instruments. The objective of this study was to evaluate the antimicrobial effects of ozonated water on the sanitization of dental instruments that were contaminated by Escherichia coli, Staphylococcus aureus, Candida albicans and the spores of Bacillus atrophaeus. A total of one hundred and twenty standardized samples of diamond dental burs were experimentally contaminated with E. coli [ATCC 25922], S. aureus [ATCC 6538] and C. albicans [ATCC 18804] and the spores of B. atrophaeus [ATCC 6633] for 30 min. After the contamination, the samples were exposed to ozonated water [10 mg/L O3] for 10 or 30 min. The control group was composed of samples that were exposed to distilled water for 30 min. After the exposure to the ozonated water, 0.1 mL aliquots were seeded onto BHI agar to count the colony-forming units per milliliter [CFU/mL] of E. coli, S. aureus, and B. atrophaeus. Sabouraud dextrose agar was used to count the CFU/mL of C. albicans. The results were subjected to an analysis of variance and the Tukey test. For all of the microorganisms studied, the ozonated water reduced the number of CFU/mL after 10 and 30 min of sanitization, and this microbial reduction was dependent on the duration of the exposure to the ozonated water. E. coliexhibited the greatest reduction in CFU/mL [2.72-3.78 log] followed by S. aureus [2.14-3.19 log], C. albicans [1.44-2.14 log] and the spores of B. atrophaeus [1.01-1.98 log]. The ozonated water was effective in reducing the CFU of E. coli, S. aureus, C. albicans and B. atrophaeus spores, suggesting that ozonated water can be used for the sanitization of dental instruments

ABSTRACT

The aim of this work was to perform the histological characterization of the C. sativa leaves of three Portuguese cultivars to establish comparison among the leaves of the different quadrants in accord and with the cardinal points of the tree top and among different cultivars of this species, using light microscopy (OM) and scanning electron microscopy (SEM). Measurements were also carried out for the leaf tissue thickness, stomatal density, leaf area in the four tree top quadrants. The leaves turned to the North had lesser thickness of mesophyll mainly due to lower amount of palisade parenchyma. The stomatal density was significantly lower in these leaves, unlike the leaf area that has the highest expression.

ABSTRACT

Introdução: A violência é um fenômeno endêmico e suas causas são multifatoriais, envolvendo aspectos biológicos, econômicos e socioculturais. Dentre os vários tipos de violência urbana, as agressões físicas e com armas vêm tomando um lugar de destaque nos serviços de saúde pelas sequelas que acarretam. O objetivo do presente estudo retrospectivo e quantitativo consistiu em determinar a prevalência da perda do globo ocular devido a agressões físicas e armas a partir de prontuários de pacientes mutilados faciais da Clínica de Prótese Buco-Maxilo-Facial da Universidade Federal de Pernambuco û UFPE. Métodos: A amostra constituiu-se de 263 pacientes reabilitados com prótese ocular, dos quais 53 foram selecionados por apresentarem trauma ocular associado à violência urbana. O perfil sociodemográfico e econômico evidenciou que eram predominantemente jovens e adultos de até 49 anos (66,0%), do sexo masculino (79,2%), procedentes do Recife e sua Região Metropolitana (63,4%), com baixa escolaridade e renda individual de até dois salários mínimos. Resultados: Os casos de traumatismos por armas de fogo foram mais prevalentes (73,6%) do que por agressão física, tendo sido a rua o principal espaço social (88,4%) para a expressão da violência. Conclusão: Os autores concluem que o controle de traumatismos por causas externas dessa natureza está na dependência de uma abordagem socioecológica da saúde.


Introduction: The violence is an endemic and multifactorial phenomenon, wich involves biological, economical and social aspects. Among the various types of urban violence, assault and use of weapons are taking a prominent place in health services because of the sequels that they lead. The aim of this retrospective study is to determine quantitatively the prevalence of loss of the eyeball due to physical assaults and to use of weapons through the medical records of mutilated facial patients attended in Maxillofacial Prosthesis Clinic at the Universidade Federal de Pernambuco (UFPE). Methods: The sample was 263 patients rehabilitated with ocular prosthesis, 53 from them were selected because they presented ocular trauma associated with urban violence. The socio-demographic and economic profile revealed that they were predominantly young people and adults up to 49 years (66.0%), males (79.2%), coming from the Metropolitan Region of Recife (63.4%), with low education level and individual income up to two minimum wages. Results: The cases of injuries caused by firearms were more prevalent (73.6%) than by physical aggression, and the street was the main social place where that happened (88.4%). Conclusion: The authors conclude that the control of injuries from external causes depends on a socio-ecological approach to health.

ABSTRACT

Purpose: To present a case report of a patient with amelogenesis imperfecta rehabilitated with 26 CAD-CAM all-ceramic fully sintered zirconia crowns.Case description: A male subject, 28 year-old, sought dental treatment presenting a clinical condition compatible with amelogenesis imperfecta. All teeth had yellow, brown, and white areas of weak enamel. Composite restorations were present on teeth 14, 16, 24, 25, 26, 27, and 46; dental caries were shown on teeth 36, 37, and 47. Hipersensitivity was reported. The treatment included fully sintered zirconia crowns for all teeth, using a CAD-CAM system. No problems of marginal adaptation of the crowns were detected, and the final results were satisfactory for both the patient and the clinician. Conclusion: The clinical rehabilitation of an amelogenesis imperfecta case is a challenge, and a multidisciplinary approach is required. Zirconia all-ceramics crowns are an excellent option to restore dental aesthetics as the opaque zirconia coping can mask dischromic abutments, and the crowns have biocompatibility and improved physical properties.


Objetivo: Apresentar o caso clínico de um paciente com amelogenesis imperfecta, que foi reabilitado com 26 coroas CAD-CAM de zircônia totalmente sinterizada. Descrição do caso: Um sujeito do sexo masculino, 28 anos, procurou tratamento odontológico apresentando uma condição clínica compatível com amelogenesis imperfecta. Todos os dentes tinham áreas amarelas, marrons e brancas de esmalte enfraquecido. Havia restaurações de resina composta nos dentes 14, 16, 24, 25, 26, 27 e 46; cárie dentária estava presente nos dentes 36, 37 e 47. Relatou-se hipersensibilidade dentária. O tratamento incluiu coroas de zircônia totalmente sinterizada para todos os dentes, usando um sistema CAD-CAM. Nenhum problema de adaptação marginal das coroas foi detectado e os resultados finais foram satisfatórios para ambos o paciente e o clínico. Conclusão: A reabilitação clínica de amelogenesis imperfecta é um desafio e a abordagem multidisciplinar deve ser mandatória. As coroas de zircônia são uma excelente opção para a reabilitação de pacientes com esta anomalia, pois o opaco dos copings de zircônia pode mascarar as diferentes cores dos pilares e o resultado final é esteticamente aceitável, com biocompatibilidade e propriedades físicas superiores.

ABSTRACT

Nile tilapia, Oreochromis niloticus, of both sexes were reared in freshwater and exposed to 0.5, 1.0 and 2.5mg L-1 of waterborne copper for a period of 21 days. Liver and gill samples were collected after 21 days of exposure to copper and lesions were analyzed by light microscopy. The main histopathological changes observed in gills exposed to the highest concentration were edema, lifting of lamellar epithelia and an intense vasodilatation of the lamellar vascular axis. Although less frequent, lamellar fusion caused by the filamentar epithelium proliferation and some lamellar aneurisms were also found. The liver of control group exhibited a quite normal architecture, while the fish exposed to copper showed vacuolation and necrosis. These hepatic alterations were more evident in fish exposed to 1.0 and 2.5mg L-1 copper concentrations. The number of hepatocytes nucleus per mm² of hepatic tissue decreased with the increase of copper concentration. In contrast, the hepatic somatic index was high in fish exposed at 2.5mg L-1 of copper. In short, this work advance new knowledge as influence of copper in the gill and liver histology of O. niloticus and demonstrated that their effects could be observed at different concentrations.


Tilápia do Nilo, Oreochromis niloticus, de ambos os sexos foram mantidas em água doce e expostas a concentrações de 0.5, 1.0 e 2.5mg L-1 de sulfato de cobre durante um período de 21 dias. Amostras de fígado e de brânquia foram coletadas após o tempo de exposição e as lesões foram analisadas por microscopia óptica. As principais alterações histopatológicas observadas nas brânquias foram edema, "lifting" do epitélio lamelar e uma intensa vasodilatação do eixo lamelar. Embora menos freqüentes, a fusão lamelar causada pela proliferação do epitélio filamentar e alguns aneurismas lamelares também foram observadas. O fígado do grupo controle exibiu uma arquitetura normal, enquanto os dos peixes expostos ao cobre apresentaram vacuolização e necrose. Estas lesões hepáticas foram mais evidentes nos peixes expostos a concentrações de cobre de 1.0 e 2.5mg L-1. O número dos núcleos dos hepatócitos / mm² de tecido hepático decresceu com o aumento da concentração de cobre. Em contraste, o índice hepatossomático foi mais elevado nos peixes expostos a 2.5mg L-1 de cobre. Em resumo, este trabalho acrescenta nova informação sobre a influência do cobre ao nível da histologia da brânquia e do fígado de O. niloticus e demonstra que os seus efeitos podem ser observados em diferentes concentrações.

ABSTRACT

Potassium-40 was determined in soil in an area with 40,000 m² situated in the western State of Pernambuco, Brazil. For radiometric measurements, the gamma spectrometry method with a high purity germanium (HPGe) detector was used. Sampling of 78 soil samples has been performed at intervals of 25 m. The specific activities of 40K were calculated based on the photopeak of 1.46 MeV. Values from 541 to 3,572 Bq kg-1 were obtained (mean of 1,827 Bq kg-1). These values allowed the determination of the elemental concentrations as well as the absorbed dose rates in air, 1 m above the ground. The values varied from 1.7 to 11.5 percent (mean of 6 percent) and from 23.4 to 154.3 nGy h-1 (mean of 79 nGy h-1), respectively.


A radioatividade do 40K foi determinada em solo em uma área de aproximadamente 40.000 m² localizada no Estado de Pernambuco, Brasil. Para as medidas radiométricas foi usado o método de espectrometria gama com detector de germânio de alta pureza (HPGe). A amostragem perfaz um total de setenta e oito amostras de solo coletadas em intervalos de 25 m. As atividades específicas do 40K foram calculadas com base no fotopico gama de 1,46 MeV. Foram obtidos valores que variaram de 541 a 3.572 Bq kg-1 (média aritmética de 1.827 Bq kg-1). Com base nestes cálculos, obteve-se concentrações elementares e doses absorvidas no ar a 1 m, derivadas da contribuição do 40K no solo, onde os valores obtidos variaram respectivamente de 1,7 a 11,5 por cento (média 6 por cento) e 23,4 a 154,3 nGy h-1 (média 79 nGy h-1).

ABSTRACT

Staphylococcus spp are not usually isolated from the oral cavity, and when this occurs, they are considered to belong to the transitory microbiota. Individuals with periodontal disease represent possible reservoirs of these opportunistic bacteria in the oral cavity. The use of antibiotics for treatment of periodontal disease or other infections may predispose to the increase of the number of Staphylococcus spp. in the oral cavity. These microorganisms easily become resistant to antibiotics, and may result in superinfection. The purpose of this study was to evaluate the presence of Staphylococcus spp. in the oral cavity and in periodontal pockets of patients with chronic periodontitis, identify the isolates and verify the relationship between the presence of Staphylococcus spp. in the oral cavity and presence of periodontal pockets. The study included eighty-eight patients, 25-60 years of age, with chronic periodontitis, and at least two sites with probing depth > 5 mm. Individual data examination was assessed. Then, samples were colleted from the periodontal pocket with the aid of paper tips and from the oral cavity through mouth rinses. Out of the total of patients, 37.50% presented Staphylococcus spp. in the periodontal pocket and 61.36% in the oral cavity, 27.27% presented the bacteria in both sites. S. epidermidis was the most prevalent specie in the periodontal pocket (15.9%) and oral cavity (27.27%). The occurrence of higher proportions of nonresident's microorganisms in subgingival samples and oral sites may represent significant problem in causing and maintaining periodontal infections.


Staphylococcus spp. não são usualmente isolados a partir da cavidade bucal. Quando presentes, são considerados pertencentes à microbiota transitória. Indivíduos que apresentam doença periodontal representam possíveis reservatórios dessas bactérias oportunistas na cavidade bucal. O uso de antibióticos para o tratamento da doença periodontal ou outras infecções pode predispor o aumento do número de Staphylococcus spp. na boca, pois estes adquirem facilmente resistência aos antibióticos, podendo resultar em superinfecção. O objetivo deste estudo foi verificar a presença de Staphylococcus spp. na cavidade bucal e nas bolsas periodontais de pacientes com periodontite crônica; identificar as cepas isoladas; verificar a relação entre a presença de Staphylococcus spp. na cavidade bucal e presença de bolsa periodontal. Participaram deste estudo 88 pacientes, entre 25 e 60 anos de idade e apresentando periodontite crônica, com pelo menos dois sítios com profundidade de sondagem maior ou igual a 5mm. Após anamnese e exame clínico periodontal foram feitas coletas de material da bolsa periodontal com cones de papel e da cavidade bucal por meio de bochechos. Do total de pacientes 37,50% apresentaram Staphylococcus spp. na bolsa periodontal e 61,36% na cavidade bucal, sendo que 27,27% apresentaram a bactéria nos 2 sítios. S. epidermidis foi a espécie mais prevalente para bolsa periodontal (15,9%) e cavidade bucal (27,27%). Não houve diferença estatística significante quanto à presença desses microrganismos entre as faixas etárias e aumento da profundidade de sondagem. A presença de bactérias oportunistas na cavidade bucal pode representar dificuldades para a manutenção do tratamento periodontal.
