Abstract The aim of the present study was to compare the sensitivity and specificity of pain scales used to assess dentin hypersensitivity (DH). The preferred scale, and toothbrushing habits of participants were also investigated. This cross-sectional study was conducted with students and employees of a Brazilian Federal University who presented DH. The participants answered a questionnaire about their toothbrushing and drinking habits. Hypersensitive and non-sensitive teeth were submitted to tactile and ice stick stimuli. Then, the subjects marked their pain level in the visual analogue (VAS), numeric scale (NS), faces pain scale (FPS) and verbal evaluation scale (VES). DH was also assessed by Schiff scale (SS). The data were analyzed by Wilcoxon and Chi-Square tests, as well as by ROC curve. The mean age of the sample (56 women, 16 men) was 27.8 years. The most prevalent acidic beverage was coffee (36.0%) and the most preferred scale was the NS (47.2%). The pain level was statistically higher in teeth with DH compared to teeth without DH (p < 0.05). The accuracy ranged from 0.729 (SS) to 0.750 (NS). The highest sensitivity value was 81.9% for NS. The SS presented the highest specificity (91%). The visual analog, numerical, verbal evaluation, faces pain, and Schiff scales were accurate for DH diagnosis. The Schiff scale was the preferred scale for DH assessment.

RESUMO. A contagem de células somáticas (CCS) do leite cru refrigerado reflete a ocorrência de mastite no rebanho e manejo da propriedade rural. Portanto, este trabalho objetivou avaliar a CCS do leite cru refrigerado e seus fatores determinantes em propriedades leiteiras de Viçosa, estado de Minas Gerais. Mensalmente, foram coletadas amostras de leite de 44 tanques de refrigeração durante o ano de 2012. Um questionário estruturado foi aplicado para avaliar as características de produção e manejo dos rebanhos. Houve variações significativas (p < 0,05) na CCS média do leite, sendo menores nos meses de junho a agosto. Maiores CCS médias e porcentagens de amostras acima do limite estabelecido pela legislação foram observadas em meses de maiores precipitações de chuva e temperatura ambiente (p < 0,05). A ordenha mecânica, menor produção de leite, produtividade, procedimentos inadequados de ordenha, higiene dos equipamentos e qualidade da água são fatores que influenciaram (p < 0,05) a CCS do leite cru refrigerado. A capacitação dos ordenhadores é necessária para produção de leite com baixa CCS.

ABSTRACT. The somatic cell count (SCC) of refrigerated raw milk reflects the occurrence of mastitis in the herd and the management of rural property. Therefore, this study aimed to evaluate the SCC of the refrigerated raw milk and its determinant factors in dairy properties of Viçosa, State of Minas Gerais. Monthly, milk samples were taken from 44 cooling tanks during 2012. A structured questionnaire was applied to evaluate the production and management characteristics of the herds. There was a significant variation (p < 0.05) in the mean SCC of the milk, which was lower from June to August. Higher mean SCC and percentages of samples above the limit set by the legislation were observed in months of higher rainfall and ambient temperature (p < 0.05). Mechanical milking, lower milk yield, productivity, inadequate milking procedures, equipment hygiene, and water quality were all factors that influenced (p < 0.05) the SCC of raw refrigerated milk. Milker training is required for production of low SCC milk.

Resumo Este estudo transversal objetiva traçar o perfil e conhecer as demandas dos usuários que buscaram os serviços públicos de reabilitação de Belo Horizonte, Minas Gerais. Foram analisados dados de 516 usuários acolhidos por meio do Protocolo de Levantamento de Problemas para a Reabilitação (PLPR), que permite a coleta de informações sobre a saúde, contexto social e inclui uma Breve Descrição Funcional (BDF) com 25 itens, em 10 domínios. A maioria dos usuários era de mulheres, média de idade de 57 anos e 54% declararam ser o responsável pela renda familiar. Dificuldade grave ou completa foi relatada por 87%, em pelo menos um dos itens da BDF, sendo os domínios Dor e Mobilidade os de maior incapacidade. A demanda por profissionais foi, principalmente, para Fisioterapeuta (89%), e Psicólogo (14%); 77% foram indicados para iniciar o tratamento na Atenção Básica (AB) e 21% na Atenção Especializada (AE). Aqueles que iniciaram na AE eram mais jovens; com maior número de qualificadores altos e elevada pontuação na BDF, indicando maior limitação/restrição funcional. Espera-se que as informações disponibilizadas pelo PLPR possam contribuir para a organização do fluxo e o planejamento de ações.

Abstract The cross sectional study aims to create the patients’ profile and understand their demands for seeking public rehabilitation services from Belo Horizonte. Data were analyzed from 516 patients who gained entry into the health care system by means of the Protocol for Identification of Problems for Rehabilitation (PLPR). It allows for gathering information related to one’s health and the social context, including a brief functional description (BFD) with 25 items. Most patients were females, mean age of 57 years, and 54% declared to be responsible for the family income. Severe or complete difficulty in at least one item from the BFD was reported by 87%. Pain and Mobility domains showed greater disability. The patient’s demand for services referred them mostly to physical therapy (89%), and psychology (14%); 77% were referred to basic care (BC) and 21% to specialized care (SC). Those that started rehabilitation in SC were younger, had increased number of high ratings in item’s qualifiers and higher total score in the BFD, indicating increased functional limitation and restriction. It is intended that the information provided by the PLPR may contribute to the organization of patients’ flow and the planning of actions.

Objetivo: Este estudo transversal visa avaliar a validade discriminante do Teste de Aprendizagem Auditivo-Verbal de Rey (RAVLT), ao comparar uma amostra de idosos normais com uma de pacientes na fase inicial da doença de Alzheimer (DA). Métodos: Pacientes na fase inicial da DA (n = 35) e controles saudáveis (n = 35) pareados de acordo com a idade e a escolaridade foram submetidos ao Teste de Aprendizagem Auditivo-Verbal de Rey, ao Miniexame do Estado Mental e à Escala de Depressão Geriátrica. O desempenho dos dois grupos foi comparado por meio do teste de Mann-Whitney em cada etapa do RAVLT e, mediante a análise ROC, foi avaliada a validade discriminante do teste nas duas populações estudadas. Resultados: O grupo na fase inicial da DA teve desempenho significativamente pior em todas as etapas do RAVLT quando comparado ao grupo controle, e as etapas demonstraram bom poder diagnóstico, com áreas sobre a curva ROC oscilando entre 0,806 e 0,989 (A1 = 0,806; A2 = 0,869; A3 = 0,958; A4 = 0,947; A5 = 0,989; A6 = 0,962; A7 = 0,985; TOTAL = 0,975; LOT = 0,895; REC = 0,915). Conclusão: Os resultados sugerem que o Teste de Aprendizagem Auditivo-Verbal de Rey é eficaz para discriminar idosos normais de idosos na fase inicial da doença de Alzheimer.

Objective: This transversal study aims to evaluate the discriminant validity of the Rey Auditory Verbal Learning Test (RAVLT) by comparing a sample of normal elderly with a patient at the initial stage of Alzheimer’s disease. Methods: Age and educational attainment matched patients at the initial stages of Alzheimer’s disease (n = 35) and normal elderly (n = 35) were submitted to the Rey Auditory Verbal Learning Test, Mini Mental State Examination and the Geriatric Depression Scale. The performance of the two groups was compared using the Mann-Whitney test at each stage of the RAVLT and by ROC analysis the discriminant validity of the test in both populations was evaluated. Results: The group at the initial stages of Alzheimer’s disease had significantly worse performance in all steps of the RAVLT compared to the control group, and the steps showed good diagnostic power, with areas under the curve ranging between 0.806 and 0.989 (A1 = 0,806; A2 = 0,869; A3 = 0,958; A4 = 0,947; A5 = 0,989; A6 = 0,962; A7 = 0,985; TOTAL = 0,975; LOT = 0,895; REC = 0,915). Conclusion: The results suggest that the Rey Auditory Verbal Learning Test is effective for discriminating normal elderly seniors from the ones in early stages of Alzheimer’s disease.
