Associação entre a doença periodontal e doenças sistêmicas crônicas: revisão de literatura

Periodontal disease has been increasingly associated as a supporting factor, and even a precursor to some systemic diseases. Just aim of this paper was to analyze by reviewing the literature, the possible mechanisms involved in the etiopathogenesis of periodontal disease that are common to the current systemic diseases such as obesity, atherosclerosis, diabetes and rheumatoid arthritis. The articles were analyzed with in the publication period of the years 2006 to 2011 and were surveyed in the databases PubMed, LILACS and SciELO. Of a total of 907 articles found by searching the indices and their associations, were selected by inclusion criteria 93 articles. For the preparation of this literature review, only 24 articles were selected because they are based on inflammatory mechanisms, metabolic and infectious, where the considerations for the strongest associations in the literature. This literature review reinforces the association of periodontal disease with systemic diseases analyzed due to presence of inflammatory and immunological mechanisms and similar synergism betwen the two diseases, but some hypotheses still need further clarification. The professional should stick to recent discoveries associations to promote periodontal treatment in preventing the development of systemic diseases, as well as in maintaining the systemic health of patients already suffering from chronic systemic diseases.

Exercício físico aeróbio para promoção da saúde de pacientes com doença de Alzheimer

Introdução: Sabe-se que a prática regular e sistematizada de atividade física é uma eficiente estratégia para evitar a deterioração cognitiva e funcional associada à Doença de Alzheimer (DA), uma doença progressiva, degenerativa e irreversível. Na população idosa os benefícios observados com a prática de exercícios físicos aeróbios já se encontram bem estabelecidos, contudo pouco ainda se sabe quanto à prática deste tipo de atividade em pacientes com DA. Em estudos realizados com modelo animal pode-se observar que o exercício físico aeróbio foi capaz de reduzir os níveis da proteína β-amilóide, sendo esta uma proteína característica da DA, que provoca degeneração no cérebro dos pacientes. A redução dos marcadores característicos da doença pode promover benefícios para os pacientes. Objetivos: Promover a prática de exercícios físicos para promoção/manutenção da saúde de pacientes com DA. Métodos: O estudo está sendo desenvolvido no PRO-CDA (Programa de Cinesioterapia Funcional e Cognitiva em Idosos com Doença de Alzheimer), projeto de Extensão do Departamento de Educação Física da UNESP – Campus Rio Claro, vinculado ao Núcleo Local UNESP-UNATI. O projeto atende atualmente 34 pacientes, divididos em dois grupos: Grupo Convívio Social e Grupo Exercício. O primeiro tem por objetivo desenvolver a adaptação do paciente à rotina do projeto. Já o segundo grupo busca promover os benefícios observados com a prática de atividade física nos pacientes participantes. Ambos os grupos realizam atividades três vezes na semana, com 60 minutos de duração cada sessão. O projeto conta com a participação de alunos de graduação, dos cursos de educação física, pedagogia e biologia, bem como discentes de pós-graduação da UNESP, além de aprimorandos graduandos e graduados dos cursos de educação física, fisioterapia, gerontologia e psicologia de outras universidades, que atuam sob a coordenação de docentes vinculados ao Departamento de Educação Física e de Educação. Resultados: Por se tratar de um protocolo de intervenção motora iniciado recentemente, o presente estudo ainda não apresenta resultados. Contudo protocolos de atividade física desenvolvidos anteriormente no PRO-CDA evidenciam melhora na realização de atividades de vida diária, manutenção das funções cognitivas, qualidade de vida e redução dos distúrbios de comportamento nos pacientes participantes. Espera-se que o protocolo de exercício físico aeróbio possa influenciar positivamente os participantes do projeto, com melhora na qualidade de vida, tanto de pacientes como de cuidadores, redução de sintomas depressivos, melhora dos distúrbios do sono e da condição motora.

Antropometria da mão humana: influência do gênero no design ergonômico de instrumentos manuais

The wrong sizing of handle instruments can generate ergonomic problems. To know the anthropometry of the hands is indispensable for a correct sizing, especially how much the gender influences in this aspect. The objective of this study was quantitatively to evaluate the influence of the sort in the anthropometry of the hand human being. The results indicate that the differences are significant and that this factor must be considered in design of manual instruments.

Structure, microstructure, and selected mechanical properties of Ti-Zr-Mo alloys for biomedical applications

New titanium alloys for biomedical applications have been developed primarily with the addition of Nb, Ta, Mo, and Zr, because those elements stabilize the β phase and they don’t cause cytotoxicity in the organism. The objective of this paper is to analyze the effect of molybdenum on the structure, microstructure, and selected mechanical properties of Ti-15Zr-xMo (x = 5, 10, 15, and 20 wt%) alloys. The samples were produced in an arc-melting furnace with inert argon atmosphere, and they were hot-rolled and homogenized. The samples were characterized using chemical, structural, and microstructural analysis. The mechanical analysis was made using Vickers microhardness and Young’s modulus measurements. The compositions of the alloys were sensitive to the molybdenum concentration, indicating the presence of α’+α”+β phases in the Ti-15Zr-5Mo alloy, α”+β in the Ti-15Zr-10Mo alloy, and β phase in the Ti-15Zr-15Mo and Ti-15Zr-20Mo alloys. The mechanical properties showed favorable values for biomedical application in the alloys presenting high hardness and low Young’s modulus compared with CP-Ti.

Effect of the substitutional elements on the microstructure of the Ti-15Mo-Zr and Ti-15Zr-Mo systems alloys

Titanium alloys have excellent biocompatibility, and combined with their low elastic modulus, become more efficient when applied in orthopedic prostheses. Samples of Ti-15Mo-Zr and Ti-15Zr-Mo system alloys were prepared using an arc-melting furnace with argon atmosphere. The chemical quantitative analysis was performed using an optical emission spectrometer with inductively coupled plasma and thermal conductivity difference. The X-ray diffractograms, allied with optical microscopy, revealed the structure and microstructure of the samples. The mechanical analysis was evaluated by Vickers microhardness measurements. The structure and microstructure of alloys were sensitive to molybdenum and zirconium concentration, presenting α′, α″ and β phases. Molybdenum proved to have greater β-stabilizer action than zirconium. Microhardness was changed with addition of molybdenum and zirconium, having Ti-15Zr-10Mo (436 ± 2 HV) and Ti-15Mo-10Zr (378 ± 4 HV) the highest values in each system.

Diagnóstico diferencial entre Doença de Crohn e Hidradenite Supurativa: relato de caso

Crohn’s disease is a chronic infl ammatory bowel disease with segmental transmural infl ammation, which complicate with formation of fi stulas and abscesses. The hidradenitis suppurativa (HS) is characterized by recurrent abscesses, with a predilection for areas rich in apocrine glands such as the axillary, inguinal and perineal. The differential diagnosis between these diseases is diffi cult and may compromise treatment. Report case: C.R.M.A., 40 year-old, female, white, ileal and colonic Crohn’s disease complicated with perianal and rectovaginal fi stula for 12 years, treated with biological therapy since May 2010. In Sep/2010 presented with an abscess in the buttock D with purulent discharge refractory to the use of ciprofl oxacin and metronidazole. USG: collection of 30 cm3 in buttock D. The diagnosis was HS and the patient underwent extensive surgical removal of the affected areas (10 x 2 cm) with healing by secondary intention. Skin graft performed unsuccessfully in Dec/2010. The patient returned in jan/2011 with a new fi stula at the site of resection, consistent with Crohn’s disease. In fev/2011 underwent drainage of abscesses and placement of setons in perianal fi stulas. Currently in therapy with good biological evolution of fi stulas. The prevalence of HS varies from 0.3 to 4% of the population in general. The axilla is the region most affected and perianal lesions are associated with greater weakness. There are published reports of association between HS and Crohn’s disease sporadically and further studies are needed to assess a common pathogenesis. The differential diagnosis should be performed in all cases planning immediate treatment, avoiding complications and worsening of the patient’s quality of life.

Detecção do rearranjo da prpoteína BCL2/JH em carcinomas epidermóides de boca e faringe

The BCL2 protein found in the internal mothocondrial membrana regulates the apoptosis preventing the programmed cell death. The translocation (14:18), detected in 70 to 85% of the follicular lymphoma, lead the super expression of BCL2 protein, by juxtaposition of BCL2 gene to the JH segment of the immunoglobulins' heavy chain gene. However, the found of the BCL2 expression in head and neck carcinoma are contradictious. OBJECTIVE: To investigate the presence of the translocation (14:18) of the BCL2 gene in head and neck carcinoma. METHOD: Sixteen DNA samplers were examinated being 13 of squamous cells carcinoma (SCC) and 3 of epidermoid (CE), y means of chain reaction of the polymerase (PCR). RESULTS: The BCL2/JH rearrangement in 2 (15%) of the CCE 13 cases and in none of the 3 cases of CE. The average of the frequency of molecules with rearrangement was 46,44x107. Was not observed association between the rearrangement presence and the exhibition to tobacco and alcohol (p=0, 6545). CONCLUSION: Different from the results found in follicular lymphoma, the presence of the translocation (14; 18) in head and neck carcinomas is not common and, when it occurs, it can be an occasional mutation not associated to exhibition to the tobacco and alcohol.
