The objectives of this work were to determine the micelial growth curve of the pathogen and the sensitivity to some fungicides potencially efficient to disease control. The optimum temperature range for micelial growth of Phyllosticta sp, was between 25 and 27.5 degrees C. The maximum and minimum temperatures for micelial growth were 32.5 degrees C and 10 degrees C. Temperatures of 5 and 35 degrees C completely inhibited the growth of the isolates. Total inhibition of the micelial growth was observed with captan and mancozeb (1000 mg a.i./ml) and triadimenol (100 mg a.i./ml). Partial reduction of the micelial growth was observed with iprodione, methyl tiofanate and chlorothalonil until 1.000 mg/ml. The chemical control of PLS was studied in a commercial area of ginger ''Gigante'', in Morretes, PR, where 18 sprays were carried out, with a break of 7 to 10 days, from December to April. The highest reduction of the area under the disease progress curve standardized (AUDPCs) was observed with the spray of chlorothalonil. With the application of dithianon, cupper oxychloride, folpet, mancozeb and captan it was observed AUDPCs between 15.05 and 18.61 lesions/leaf. Iprodione, benomyl, triadimenol and methyl tiofanate did not control the disease (AUDPCs between 20.03 and 25.04 lesions/leaf). The AUDPCs in the check plot was 35.88 lesions/leaf. There was no significant difference of vigor and of ginger yield between fungicide treatments. The cupper oxichloride was phytotoxic to ginger.

Considerando o Diabetes mellitus (DM) como um relevante problema de saúde no Brasil e a importância das estimativas de prevalência para planejamento e estratégias em saúde pública, propôs-se este trabalho com o objetivo de estimar a razão de prevalências do DM nos diferentes estados brasileiros nos períodos de 2002 a 2004 e 2005 a 2007. Trata-se de estudo descritivo, baseado em dados da população brasileira com diagnóstico de DM cadastrada no Sistema de Informação da Atenção Básica (SIAB) junto ao Ministério da Saúde. As taxas de prevalência foram calculadas para o período de 2002 a 2004 e para 2005 a 2007, e posteriormente estimou-se a Razão de Prevalências (R) por ponto e por intervalo de 95% de confiança (IC95%). Observou-se alta prevalência de DM nos estados brasileiros com aumento significativo (R>1; IC95%>1) entre os períodos em todos os estados brasileiros, com destaque para o Distrito Federal (R=1,9800; IC95%=1,97241,9876) e o estado do Maranhão (R=1,5217; IC95%=1,51981,5235). Pode-se concluir que houve aumento significativo na prevalência de DM no Brasil de 2002 a 2007, sinalizando para a necessidade de formulação de estratégias de prevenção e controle da doença.

The increase of the retentive areas of bacterial plaque can be observed in patients who use dental braces in the mouth. The difficulty of making hygienic is one of the problems that this particular group of patients faces day by day, and consequently, the establishment of gingival inflammation becomes more frequent. The objective of this case report is to show the importance of the periodontist in preventing and promoting health to the users of dental braces, aimed at education and motivation as one of the priorities of this treatment. The ESA patient, 29 years old, male, attended the dental office of a periodontist, sent by the orthodontist, due to the extensive area of gingival hyperplasia and gingivitis, in both arches. The possibility of taking out the dental braces was considered by the orthodontist, but after the periodontist evaluation, this step was procrastinated. Thus, the periodontist started the adequacy of the oral environment together with the work of education and promotion of health, which lasted until the complete recovery of the healthy gingival condition of the patient. In this way, it is possible to observe the relevance of the work of the periodontist in the application of preventive methods in oral health for orthodontic patients. The motivation of these patients in relation to the orientations of buccal hygienic, maintenance of oral health and diet should not be considered as secondary and should be prioritized, because only in this way it would be possible to reach a good occlusion, without esthetic and functional prejudice.

Dental plaque is the principal etiological agent of periodontal disease, one of oral diseases more prevalent in the world. Due existence of relation between periodontal disease and oral hygiene, on the point of periodontal view, it was developed a growing interesting by experimental research and by clinical investigations. The knowledge of problem, its extension, severity, hypothetic cause is so valuable to establish prevention, control and treatment acts. In this form, the use of plaque index becomes more and more often, being valuable the determination of discriminatory power of them. The aim of this work was to describe and analyze principal forms to register of dental plaque aiming to subsidize the researcher and dental surgeon on adoption of most adequate method for their case. Data bases: Medline, Lilacs and BBO were consulted without limit to identify the format of register of each index described on literature. It was observed the use of Oral Hygiene Index on diverse ways like: clinical evaluation of dental plaque, in products evaluation works and dental Office; patients monitoring; instruction about hygiene and oral hygiene technique. It was noted that dental plaque indexes are useful and allows the register of different forms point out the importance of its use on clinical and researches practice.

The program of diagnosis and prevention of oral cancer of Univag - University Center aims to increase preventive and early oral diseases with emphasis on oral cancer, aiming to reduce the morbidity and mortality through educative actions, spreading of the auto-examination, performed by dental students of UNIVAG since the second half of 2005 to the present day. The dental students of 1st, 2nd, 3rd and 4th semesters were trained using practice-theoretical classes, for realization the exams preventives and diagnostics, such as self-examination, exfoliative cytology and biopsy of oral mucosa, and even present educative actions. Analyzing the preliminary results were observed increase in the number of diagnoses and referral of diagnosed with oral cancer for treatment in referral services. It was concluded that the program of diagnosis and prevention of oral cancer can make possible early diagnosis and adoption of preventive measures, consequently improving survival rates and life quality in population.
Controle alternativo de Colletotrichum acutatum agente causal da queda prematura dos frutos cítricos
Resumo:
A queda prematura dos frutos cítricos (QPFC), causada por Colletotrichum acutatum, dados os grandes prejuízos que têm causado aos produtores, constitui-se numa doença de grande importância econômica. O controle da doença é feito predominantemente mediante uso de fungicidas, que eleva o custo de produção e afeta negativamente o meio ambiente. Diante disso, este trabalho teve por objetivo buscar um método alternativo de controle da QPFC, mediante o uso de agentes de biocontrole ou de biofertilizantes. Diferentes concentrações de biofertilizantes (originários de duas fontes distintas e denominados de Bio1 e Bio 2); três isolados de Bacillus subtilis (ACB-69; 72 e 77) e três isolados de Trichoderma spp. (ACB-14; 37 e 39) foram testados, isoladamente ou em combinação, sob condições de laboratório, quanto à capacidade inibitória da germinação de conídios de C. acutatum. Estudaram-se, ainda, a produção de metabólitos termoestáveis por B. subtilis e o efeito sobre a germinação do patógeno. Quinze isolados de B. subtilis foram testados quanto à capacidade de prevenir a infecção por C. acutatum em flores destacadas de lima- ácida 'Tahiti' e, no campo, foram instalados dois experimentos, visando a testar ACBs e biofertilizantes no controle da doença. Verificou-se que o isolado ACB-72 (B. subtilis) e ACB-37 (T. pseudokoningii) foram os que mais inibiram a germinação do patógeno. Quanto à produção de metabólitos termoestáveis, ACB-69 e 77 foram os mais eficientes em produzir substâncias antifúngicas, e em quantidades suficientes para inibirem a germinação do patógeno. A mistura dos quatro isolados de Bacillus (ACBs: 69; 72; 77 e AP3) foi o que apresentou maior porcentagem de inibição (73%). Os biofertilizantes (Bio1 e Bio2), em concentrações acima de 10% e, quando em associação com isolados de Trichoderma spp., promoveram maiores inibições na germinação de C. acutatum. em testes com flores destacadas, verificou-se que, onde foram aplicados os ACBs 69; 76; 74 e 77, as porcentagens de pétalas sem sintomas de infecção por C. acutatum foram de 83; 92; 92 e 97%, respectivamente. Mediante avaliações a campo, verificou-se a potencialidade de B. subtilis e de biofertilizantes em controlar a doença.
