Qualidade de vida no transtorno obsessivo-compulsivo: uma revisão

CONTEXTO: O transtorno obsessivo-compulsivo (TOC) foi considerado pela Organização Mundial da Saúde como a 10ª causa de anos vividos com incapacidade, mas pesquisas sobre qualidade de vida (QV) nesse transtorno ainda são relativamente raras. OBJETIVOS: O objetivo deste trabalho foi fazer uma revisão convencional da literatura a respeito de estudos sobre qualidade de vida no TOC, publicados em português e inglês. MÉTODOS: A busca de artigos foi feita pelos sistemas MEDLINE, PsicoInfo e LILACS, cobrindo o período de 1980 a 2007, utilizando-se como palavras-chave: qualidade de vida, transtorno obsessivo-compulsivo, prejuízo funcional e incapacidade. RESULTADOS: Estudos populacionais apresentam indicadores indiretos de comprometimento na QV em pessoas com TOC, como mais desemprego, menor renda e menor índice de união conjugal estável, além de taxas relativamente altas de ideação e tentativas de suicídio. Estudos clínicos encontraram mais comprometimento na QV no TOC em comparação com algumas doenças clínicas crônicas, outros transtornos de ansiedade, quadros depressivos e mesmo esquizofrenia, em alguns aspectos. CONCLUSÃO: O impacto negativo do TOC sobre a QV de seus portadores pode ser grande, afetando vários domínios da vida e repercutindo também nos familiares. A reabilitação psicossocial deve ser vista como parte integrante essencial do tratamento e é preciso aumentar a conscientização da população sobre o problema, assim como o acesso a tratamentos adequados, para minimizar tal impacto, por vezes devastador.

Capacidade, dotação, talento, habilidades: uma sondagem da conceituação pelo ideário dos educadores

Embora o escopo deste trabalho seja de origem teórica, relata um estudo exploratório que busca situar a base de conceituação em Educação Especial para alunos Dotados e Talentosos, no Brasil, captando as definições compreendidas por profissionais da educação pela sondagem de sua opinião sobre que termos e expressões são usados, com que significados e em que situações. Os sujeitos incluíam 80 educadores interessados ou envolvidos na área (Grupo A) e 107 professores da rede pública no interior de São Paulo (Grupo B). Há poucas diferenças de opinião entre os sujeitos, nos dois grupos, com algumas exceções, principalente em questões relacionadas a nível de conhecimento e familiaridade com referencial teórico. Ambos os grupos indicam conceituação confusa, notadamente para os termos oficiais, superdotação e altas-habilidades; a maior carga de rejeição e exploração na mídia é alocada a superdotação. Os conceitos alta capacidade, alto desempenho e dotação são definidos em consonância com o referencial básico, que diferencia capacidade natural de capacidade adquirida; Talento reflete a ambiguidade encontrada na área, referindo-se, ao mesmo tempo, a capacidade natural e capacidade adquirida.

Uma análise da produção de histórias coerentes por crianças

A coerência é o processo responsável pela formação do sentido que garante a compreensibilidade de um texto. Investigações sobre o tema se caracterizam por: (a) um enfoque puramente lingüístico, ficando em aberto questões relacionadas ao desenvolvimento e aos fatores que o influenciam; e (b) examinar a coerência estabelecida pelo receptor do texto, sendo raras as investigações que abordam a perspectiva do narrador. em uma abordagem de desenvolvimento, o presente estudo examinou as possibilidades e dificuldades de crianças em estabelecer a coerência ao produzir um texto. Histórias elaboradas por crianças de 6-7 anos foram analisadas em função de indicadores específicos agrupados em um sistema de análise que expressa diferentes níveis no estabelecimento da coerência. Observou-se que o desenvolvimento da coerência se relaciona à aquisição da leitura e da escrita. Críticas são feitas quanto à ausência de um sistema de análise que contribua para o exame da coerência textual em crianças.

Development of an open case-based decision-support system for diagnosis in oral pathology

Making diagnoses in oral pathology are often difficult and confusing in dental practice, especially for the lessexperienced dental student. One of the most promising areas in bioinformatics is computer-aided diagnosis, where a computer system is capable of imitating human reasoning ability and provides diagnoses with an accuracy approaching that of expert professionals. This type of system could be an alternative tool for assisting dental students to overcome the difficulties of the oral pathology learning process. This could allow students to define variables and information, important to improving the decision-making performance. However, no current open data management system has been integrated with an artificial intelligence system in a user-friendly environment. Such a system could also be used as an education tool to help students perform diagnoses. The aim of the present study was to develop and test an open case-based decisionsupport system.Methods: An open decision-support system based on Bayes' theorem connected to a relational database was developed using the C++ programming language. The software was tested in the computerisation of a surgical pathology service and in simulating the diagnosis of 43 known cases of oral bone disease. The simulation was performed after the system was initially filled with data from 401 cases of oral bone disease.Results: the system allowed the authors to construct and to manage a pathology database, and to simulate diagnoses using the variables from the database.Conclusion: Combining a relational database and an open decision-support system in the same user-friendly environment proved effective in simulating diagnoses based on information from an updated database.

Use of reduced concentrations of tetrazolium solutions for the evaluation of the viability of peanut seed lots

The possibility of reducing the concentration of the working solution used in the tetrazolium test for peanut seeds (Arachis hypogaea L.) with or without seedcoats was studied. Tetrazolium solutions of different concentrations (0.05%, 0.075% and 0.1%) were tested at the temperatures of 35 and 40 degrees C, for determining the time needed for the seeds to reach proper staining. The efficiency of the selected treatments in evaluating the viability potential of the seeds was determined by comparing the results of the tetrazolium tests with those obtained by standard germination (using sand and rolled paper towel as substrata) and seedling emergence in the field tests. Staining the seeds without seedcoat in 0.05% tetrazolium solution for three hours at 40 degrees C yielded efficient results. on the other hand, reduced concentrations can be employed in the staining process of seeds with seedcoat; however, this method requires a higher consumption of tetrazolium salt, longer staining time as well as a higher ability and availability of time for embryo evaluation, since the cross-cutting of seeds is much more difficult in the presence of the seedcoat and the occurrence of damage to the outer surface of the cotyledons cannot be determined.

Are Working Memory Measures Free of Socioeconomic Influence?

Purpose: This study evaluated the impact of socioeconomic factors on children's performance on tests of working memory and vocabulary.Method: Twenty Brazilian children, aged 6 and 7 years, from low-income families, completed tests of working memory ( verbal short-term memory and verbal complex span) and vocabulary ( expressive and receptive). A further group of Brazilian children from families of higher socioeconomic status matched for age, gender, and nonverbal ability also participated in the study.Results: Children from the low socioeconomic group obtained significantly lower scores on measures of expressive and receptive vocabulary than their higher income peers but no significant group differences were found on the working memory measures.Conclusion: Measures of working memory provide assessments of cognitive abilities that appear to be impervious to substantial differences in socioeconomic background. As these measures are highly sensitive to language ability and learning in general, they appear to provide useful methods for diagnosing specific learning difficulties that are independent of environmental opportunity.

Performance of race instrumentation system in curved root canals: a comprehensive analysis by three study methods

In this study, curved maxillary molar root canals were instrumented with RaCe rotary system to evaluate: 1. the occurrence of canal transportation using a radiographic platform; 2. the action of the instruments on the dentin walls, centering ability and canal enlargement by analysis of digital images; and the percentage of regular dentin surfaces and debris within the canal by histological analysis. Ten mesiobuccal roots of extracted human maxillary molars were embedded in acrylic resin and sectioned at the middle and apical thirds. Root canal shaping was performed using the RaCe rotary system at 250 rpm and 1 Ncm torque. Each instrument set was used five times according to a crowndown technique in the following sequence: 40/0.10, 35/0.08, 25/0.06, 25/0.04, 25/0.02 (working length - WL), 30/0.02 (WL) and 35/0.02 (WL). Each instrument was inserted until resistance was felt and then pulled back, followed by brushing movements towards all canal walls. Each specimen was assessed by three study methods: radiographic platform, digitized image assessment and histological analysis. The radiographic platform showed lack of apical transportation. No statistically significant difference (Wilcoxon test, p>0.05) was found between the middle and apical thirds regarding instrument action on dentin walls, centering ability, area of root canal enlargement, percentage of regular dentin surfaces and debris within the root canal. It may be concluded that RaCe system is a suitable method for the preparation of curved root canals, regarding the maintenance of root canal original path, action on dentin walls, canal enlargement and removal of debris from the root canal lumen.

Perioperative evaluation of tumescent anaesthesia technique in bitches submitted to unilateral mastectomy

Background: Tumescent anaesthesia (TA) is a widely used technique in oncologic surgeries necessitating large resection margins. This technique produces transoperative and postoperative analgesia, reduces surgical bleeding, and facilitates tissue divulsion. This prospective, randomised, blind study evaluated the use of TA in bitches submitted to mastectomy and compared the effect of TA with an intravenous fentanyl bolus. A 2.5-mcg/kg intravenous fentanyl bolus (n = 10) was compared with TA using 0.275% lidocaine (n = 10) in bitches submitted to unilateral mastectomy. Sedation was performed by intramuscular (IM) injection of 0.05 mg/kg of acepromazine combined with 2 mg/kg of meperidine. Anaesthesia was induced with 5 mg/kg of intravenous propofol and maintained with isoflurane/O2. Heart and respiratory rates; systolic, mean, and diastolic arterial blood pressures; central venous pressure; SpO2; ETCO2; inspired and expired isoflurane concentrations; and temperature were measured transoperatively. Visual analogue scales for sedation and pain and the Glasgow composite and Melbourne pain scales were used for postoperative assessment. The surgeon investigated the quality of the surgical approach, considering bleeding and resection ability, and the incidence of postoperative wound complications.Results: The heart rate was lower and the end-tidal isoflurane concentration was higher in dogs treated with fentanyl than in dogs treated with TA. A fentanyl bolus was administered to 8 of 10 dogs treated with fentanyl and to none treated with TA. Intraoperative bleeding and the mammary gland excision time were lower in dogs treated with TA. The maximal mean and individual plasma lidocaine concentrations were 1426 ± 502 ng/ml and 2443 ng/ml at 90 minutes after infiltration, respectively. The Glasgow Composite Pain Scale scores were higher in dogs treated with fentanyl than in dogs treated with TA until 2 hours after extubation.Conclusions: Compared with intravenous fentanyl, TA in bitches: may be easily performed in non-inflamed, ulcerated, adhered mammary tumours; has an isoflurane-sparing effect; improves transoperative and immediate postoperative analgesia; is apparently safe for use in clinical conditions as evidenced by the fact that it did not produce any adverse signs or lidocaine plasma concentrations compatible with toxicity; does not modify the recovery time; and facilitates the surgical procedure without interfering with wound healing. © 2013 Credie et al.; licensee BioMed Central Ltd.
