Pressure Ulcer Knowledge Among Nurses in a Brazilian University Hospital

To facilitate the implementation of evidence-based skin and pressure ulcer (PU) care practices and related staff education programs in a university hospital in Brazil, a cross-sectional study was conducted to evaluate nurses` knowledge about PU prevention, wound assessment, and staging. Of the 141 baccalaureate nurses (BSN) employed by the hospital at the time of the study, 106 consented to participate. Using a Portuguese version of Pieper`s Pressure Ulcer Knowledge Test (PUKT), participants were asked to indicate whether 33 statements about PU prevention and eight about PU assessment and staging were true or false. For the 33 prevention statements, the average number answered correctly was 26.07 (SD 4.93) and for the eight assessment statements the average was 4.59 (SD 1.62). Nurses working on inpatient clinical nursing units had significantly better scores (P = 0.000). Years of nursing experience had a weak and negative correlation with correct PUKT scores (r = -0.21, P = 0.033) as did years of experience working in the university hospital (r = -.179, P <071). Incorrect responses were most common for statements related to patient positioning, massage, PU assessment, and staging definitions. The results of this study confirm that nurses have an overall understanding of PU prevention and assessment principles but important knowledge deficits exist. Focused continuing education efforts are needed to facilitate the implementation of evidence-based care.

Tetrasomy 8 in a patient with chronic lymphocytic leukemia

We report a case of a 47-year-old man diagnosed with chronic lymphocytic leukemia (CLL) with two extra copies of chromosome 8. Classical cytogenetic analysis by the immunostimulatory combination of DSP30 and interleukin 2 showed tetrasomy of chromosome 8 in 60% of the metaphase cells (48,XY,+8,+8[12]/46,XY[8]). Spectral karyotype analysis confirmed the abnormality previously seen by G banding. Additionally, interphase fluorescence in situ hybridization using an LSI CEP 8 probe performed on peripheral blood cells without any stimulant agent showed tetrasomy of chromosome 8 in 54% of analyzed cells (108 of 200). To our knowledge, tetrasomy 8 as the sole chromosomal abnormality in CLL has not been previously described. The prognostic significance of tetrasomy 8 in CLL remains to be elucidated. However, the patient has been followed up in the outpatient hospital since 2004 without any therapeutic intervention and has so far remained stable. (C) 2010 Elsevier Inc. All rights reserved.

Kaposi sarcoma and paracoccidioidomycosis in the same fragment of oral mucosa biopsy: a rare association in human immunodeficiency virus-positive patient. A case report

The immunossuppression caused by HIV infection makes the affected individuals more susceptible to some diseases including infections, neoplasms, or even the association between them. Kaposi sarcoma (KS) is the most common AIDS-related neoplasm, featured as an angioproliferative disorder. Its cause seems to be related to the human herpesvirus type 8 and it is usually associated with lower CD4+ T cell count. Oral involvement is frequent, presenting red to blue-purplish plaques, maculaes, and nodules. On the other hand, paracoccidioidomycosis (PCM) is a systemic mycosis, endemic in Latin America, caused by Paracoccidioides brasiliensis. This mycosis is not commonly related to human immunodeficiency virus (HIV) infection, although PCM can be present in immunosuppression cases. Oral lesions, as granulomatous ulcers, are often identified in seropositive patients with PCM. A rare case, in which a male HIV-positive patient presented simultaneously Kaposi sarcoma and PCM in the same fragment of oral mucosa biopsy, is described. To the best of our knowledge, this concomitant association had not been previously described. (C) 2011 Elsevier Inc. All rights reserved.

Knowledge and attitude of parents or caretakers regarding transmissibility os caries disease

Dental caries is a transmissible infectious disease in which mutans streptococci are generally considered to be the main etiological agents. Although the transmissibility of dental caries is relatively well established in the literature, little is known whether information regarding this issue is correctly provided to the population. The present study aimed at evaluating, by means of a questionnaire, the knowledge and usual attitude of 640 parents and caretakers regarding the transmissibility of caries disease. Most interviewed adults did not know the concept of dental caries being an infectious and transmissible disease, and reported the habit of blowing and tasting food, sharing utensils and kissing the children on their mouth. 372 (58.1%) adults reported that their children had already been seen by a dentist, 264 (41.3%) answered that their children had never gone to a dentist, and 4 (0.6%) did not know. When the adults were asked whether their children had already had dental caries, 107 (16.7%) answered yes, 489 (76.4%) answered no, and 44 (6.9%) did not know. Taken together, these data reinforce the need to provide the population with some important information regarding the transmission of dental caries in order to facilitate a more comprehensive approach towards the prevention of the disease.

Termo de consentimento livre e esclarecido aos usuários de clínicas odontológicas brasileiras: aspectos éticos e legais

O consentimento do paciente antes do início de qualquer procedimento é uma condição a ser respeitada pelos profissionais da odontologia, sem nenhuma exceção. É necessário que o paciente esteja ciente de seu status de saúde, de suas necessidades específicas, do propósito de cada tratamento, conheça os planejamentos alternativos (incluindo o não tratamento), saiba do seu prognóstico, riscos, consequências, limitações e se conscientize das suas responsabilidades e as do seu cirurgião-dentista, proporcionando o sucesso do tratamento. O termo de consentimento livre e esclarecido (TCLE) visa fortalecer e esclarecer a posição do paciente, estabelecendo os direitos e deveres de ambas as partes paciente e profissional. O conhecimento integral do tratamento diminuirá a ansiedade do paciente e as complicações de tratamento, promoverá maior qualidade dos serviços odontológicos e maior satisfação do dentista e do paciente. Entretanto, no Brasil, poucos artigos são encontrados e existem alguns problemas éticos envolvendo as clínicas odontológicas, no que diz respeito a este documento de esclarecimento para o paciente. Diante disso, este trabalho tem por objetivo realizar uma revisão crítica sobre o tema abordado, demonstrando a importância do TCLE na clínica odontológica brasileira e na vida profissional dos cirurgiões-dentistas.

Responsabilidade civil do cirurgião-dentista: a importância do assistente técnico

INTRODUÇÃO: a responsabilidade do cirurgião-dentista pode ser entendida como obrigações de ordem penal, civil, ética e administrativa, às quais está sujeito no exercício de sua atividade. Assim, se comprovado um resultado lesivo ao paciente - por imprudência, imperícia ou negligência -, o cirurgião-dentista estará sujeito às penalidades previstas no Código Civil, sendo obrigado a satisfazer o dano e indenizar segundo a consequência provocada. Em processos cíveis, as partes poderão contratar um assistente técnico para fornecer, aos respectivos advogados, conhecimentos técnicos e científicos inerentes ao tema. OBJETIVO: informar sobre a importância da atuação de assistentes técnicos em processos cíveis, propiciando às partes uma maior compreensão dos aspectos técnicos, éticos e legais. CONCLUSÃO: há a necessidade de um maior conhecimento, por parte dos profissionais em Odontologia, sobre os aspectos éticos e legais que norteiam a profissão.

Oral findings and dental care in a patient with myelomeningocele: case report of a 3-year-old child

Myelomeningocele (MMC) is a congenital malformation of the neural tube that occurs in the first weeks of pregnancy. This malformation refers to the caudal non-closure of the neural tube and neural tissue exposure, which lead to neurological problems, such as hydrocephalus, motor disability, genitourinary tract and skeletal abnormalities and mental retardation. Patients with MMC have an acknowledged predisposition to latex allergy and are usually at a high caries risk and activity due to poor oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing medications. This paper addresses the common oral findings in pediatric patients with MMC, discusses the strategies and precautions to deal with these individuals and reports the dental care to a young child diagnosed with this condition.

Cirurgias odontológicas em usuários de anticoagulantes orais

Em razão do crescimento do número de indivíduos submetidos à terapêutica anticoagulante também nos consultórios odontológicos, realizamos um levantamento retrospectivo de prontuários de pacientes anticoagulados com derivados cumarínicos e uma revisão sobre os protocolos de atendimento, a fim de procurar estabelecer diretrizes para um tratamento cirúrgico-odontológico adequado e seguro. A avaliação do paciente com relação ao seu nível de anticoagulação através do Índice Normatizado Internacional (INR) ou Tempo de Protrombina (TP) e a classificação da amplitude do trauma cirúrgico são fatores importantes a serem avaliados antes do procedimento cirúrgico. Nosso levantamento mostrou que, em 47 cirurgias, sem alteração da medicação sistêmica, apenas um caso apresentou hemorragia pós-operatória, controlada por manobras de hemostasia local. Desse modo, observamos que, dentre os vários protocolos propostos na literatura, a manutenção da terapia anticoagulante, com a utilização de hemostáticos locais se necessário, parece o mais adequado à maioria dos casos cirúrgicos ambulatoriais.

Leishmania spp. parasite isolation through inoculation of patient biopsy macerates in interferon gamma knockout mice

Isolation of Leishmania parasite and species identification are important for confirmation and to help define the epidemiology of the leishmaniasis. Mice are often used to isolate pathogens, but the most common mouse strains are resistant to infection with parasites from the Leishmania (Viannia) subgenus. In this study we tested the inoculation of interferon gamma knockout (IFNγ KO) mice with biopsy macerates from Leishmania-infected patients to increase the possibility of isolating parasites. Biopsies from twenty five patients with clinical signs of leishmaniasis were taken and tested for the presence of parasites. Immunohistochemical assay (IHC) and conventional histopathology detected the parasite in 88% and 83% of the patients, respectively. Leishmania sp. were isolated in biopsy macerates from 52% of the patients by culture in Grace's insect medium, but 13% of isolates were lost due to contamination. Inoculation of macerates in IFNγ KO mice provides isolation of parasites in 31.8% of the biopsies. Most isolates belong to L. (Viannia) subgenus, as confirmed by PCR, except one that belongs to L. (Leishmania) subgenus. Our preliminary results support the use of IFNγ KO mice to improve the possibility to isolate New World Leishmania species.

ScriptLattes: an open-source knowledge extraction system from the Lattes platform

The Lattes platform is the major scientific information system maintained by the National Council for Scientific and Technological Development (CNPq). This platform allows to manage the curricular information of researchers and institutions working in Brazil based on the so called Lattes Curriculum. However, the public information is individually available for each researcher, not providing the automatic creation of reports of several scientific productions for research groups. It is thus difficult to extract and to summarize useful knowledge for medium to large size groups of researchers. This paper describes the design, implementation and experiences with scriptLattes: an open-source system to create academic reports of groups based on curricula of the Lattes Database. The scriptLattes system is composed by the following modules: (a) data selection, (b) data preprocessing, (c) redundancy treatment, (d) collaboration graph generation among group members, (e) research map generation based on geographical information, and (f) automatic report creation of bibliographical, technical and artistic production, and academic supervisions. The system has been extensively tested for a large variety of research groups of Brazilian institutions, and the generated reports have shown an alternative to easily extract knowledge from data in the context of Lattes platform. The source code, usage instructions and examples are available at http://scriptlattes.sourceforge.net/.

Brazilian scientific production on pharmaceutical care from 1990 to 2009

Brazilian scientific production on pharmaceutical care was identified based on articles indexed on the Medline, Embase, Lilacs, Web of Science and International Pharmaceutical Abstracts databases. Sixty-three articles published in both national and international journals were retrieved. With regard to authors, 72.3% were from the Southeast and South Regions, and 60.8% were affiliated to public universities. In relation to the type of studies, 85.7% were descriptive, and the most frequently researched fields were community pharmacies, hospitals and primary health care units. Articles were original in 65.1% of cases, updates in 20.6%, and reviews in 7.9%. An increase in publications commenced in 2006. In 31.7% of cases, authors had adopted a bibliographical study design, 28.6% qualitative study, 23.8% intervention, and 15.9% observational study design. The most researched subjects were elderly with chronic diseases. The importance of stimulating the conducting of experimental and qualitative studies, as well as amplifying authorship affiliated with the service area, foreign authors and with research in a wide variety of practice settings were highlighted. Despite the limited quantity of articles, an increase in their number as well as in their scope and quality is expected, so as to create further knowledge that contributes to the recognition of pharmacists' actions by patient healthcare teams.

Atenção farmacêutica em farmácias e drogarias: existe um processo de mudança?

Para se conhecer a prática profissional de farmacêuticos que atuam em farmácias e drogarias, seus conhecimentos e percepções acerca da Atenção Farmacêutica (AF), realizou-se estudo descritivo com 91 farmacêuticos do município de Jundiaí-SP. A maioria era jovem (62,6% entre 20 e 29 anos), do sexo feminino (63,7%), graduada em instituições privadas (90,1%) e não proprietária do estabelecimento (87,9%). Desenvolviam atividades administrativas, técnicas e de atenção ao usuário, principalmente dispensação de medicamentos e orientação; 67,0% acompanhavam o tratamento farmacoterapêutico dos usuários, mas sem registrar informações. Para 62,7%, AF relacionava-se apenas à orientação e atendimento dispensados, mas tais atividades não eram realizadas de forma sistemática e organizada, como preconizado. Muitos (91,2%) consideravam necessário realizar trabalho mais intenso com os usuários, porém apontaram dificuldades como falta de tempo e de apoio dos proprietários e desinteresse dos usuários. Várias dessas dificuldades têm sido verificadas também em outros países, sugerindo que a prática da AF: (a) requer uma mudança estrutural e rearranjo de funções, uma vez que, atualmente, a estrutura e as atividades são adequadas à atividade comercial; (b) reflete uma crise de identidade profissional e, em consequência, falta de reconhecimento social e pouca inserção na equipe multiprofissional de saúde. O conhecimento sobre AF mostrou-se limitado, mas a situação pode vir a alterar-se à medida que as mudanças curriculares em curso surtam efeito na formação dos novos farmacêuticos.

Pharmacist professionals in the prevention of drug abuse: updating roles, and opportunities

The objective of this paper was to prepare and provide resources to pharmacists and other healthcare professionals, enabling them to carry out a critical analysis on drug abuse, acquiring knowledge in several areas that effectively contribute to their personal development in this professional field. Professionals play a crucial role in the reduction and prevention of substances abuse, since they are able to advise patient about illicit drugs, psychotropic medicines and alcohol abuse. There is an urgent need to specialize pharmacists to act in the national public health service and contribute to actions aimed at the surrounding community.

Kerteszia subgenus of Anopheles associated with the Brazilian Atlantic rainforest: current knowledge and future challenges

Background: The Atlantic rainforest ecosystem, where bromeliads are abundant, provides an excellent environment for Kerteszia species, because these anophelines use the axils of those plants as larval habitat. Anopheles (K.) cruzii and Anopheles (K.) bellator are considered the primary vectors of malaria in the Atlantic forest. Although the incidence of malaria has declined in some areas of the Atlantic forest, autochthonous cases are still registered every year, with Anopheles cruzii being considered to be a primary vector of both human and simian Plasmodium. Methods: Recent publications that addressed ecological aspects that are important for understanding the involvement of Kerteszia species in the epidemiology of malaria in the Atlantic rainforest in the Neotropical Region were analysed. Conclusion: The current state of knowledge about Kerteszia species in relation to the Atlantic rainforest ecosystem was discussed. Emphasis was placed on ecological characteristics related to epidemiological aspects of this group of mosquitoes. The main objective was to investigate biological aspects of the species that should be given priority in future studies

Students' collective knowledge construction in the virtual learning environment ""ToLigado - your school interactive newspaper""

Introduction. The ToLigado Project - Your School Interactive Newspaper is an interactive virtual learning environment conceived, developed, implemented and supported by researchers at the School of the Future Research Laboratory of the University of Sao Paulo, Brazil. Method. This virtual learning environment aims to motivate trans-disciplinary research among public school students and teachers in 2,931 schools equipped with Internet-access computer rooms. Within this virtual community, students produce collective multimedia research documents that are immediately published in the portal. The project also aims to increase students' autonomy for research, collaborative work and Web authorship. Main sections of the portal are presented and described. Results. Partial results of the first two years' implementation are presented and indicate a strong motivation among students to produce knowledge despite the fragile hardware and software infrastructure at the time. Discussion. In this new environment, students should be seen as 'knowledge architects' and teachers as facilitators, or 'curiosity managers'. The ToLigado portal may constitute a repository for future studies regarding student attitudes in virtual learning environments, students' behaviour as 'authors', Web authorship involving collective knowledge production, teachers' behaviour as facilitators, and virtual learning environments as digital repositories of students' knowledge construction and social capital in virtual learning communities.
