Análise do conteúdo de propagandas de medicamentos psicoativos

O objetivo do estudo foi descrever as figuras humanas retratadas nas propagandas de medicamentos psicoativos quanto ao gênero, a idade, a etnia e o contexto social. Foi realizada análise de conteúdo de 86 impressos publicitários inéditos divulgados em Araraquara (SP) no ano de 2005. A associação entre as categorias foi analisada usando o teste exato de Fisher. Houve predomínio de mulheres (62,8%), sendo quatro vezes mais freqüentes que os homens em propagandas de antidepressivos e ansiolíticos. A maioria era constituída de jovens adultos (72%), de etnia branca (98,8%). As pessoas estavam em lazer (46,5%), em suas casas (29%) ou em contato com a natureza (16,2%). A mensagem transmitida foi que os medicamentos tratam sintomatologias subjetivas de desconforto do dia-a-dia, induzindo a um apelo irracional que pode refletir na prescrição medicamentosa.

Saúde bucal: uma revisão crítica sobre programações educativas para escolares

Em saúde bucal, a situação epidemiológica brasileira ainda é grave devido às condições sociais e econômicas da população, à pequena parcela de investimentos que a área recebe em relação ao total do SUS e à falta de informação sobre os cuidados básicos de saúde. Embora a odontologia se mostre muito desenvolvida em tecnologia, não responde em níveis significativos às demandas dos problemas de saúde bucal da população. Nesse contexto, a educação em saúde bucal tem sido cada vez mais requisitada, considerando o baixo custo e as possibilidades de impacto odontológico no âmbito público e coletivo. A importância de práticas preventivas e educativas em saúde bucal nos levou a realizar este estudo, apontando diferentes programas odontológicos, mediante estudo de revisão, para analisá-los em suas propostas, metodologias, possibilidades e limitações, visando refletir sobre o tema com foco nos aspectos educativos que ainda desafiam os programas de saúde bucal. Identificaram-se quatro tendências nos programas analisados. O estudo apontou para a necessidade de se repensar as práticas educativas.

Alterações no perfil dos lábios de pacientes submetidos a avanços maxilares em cirurgia ortognática do tipo Le Fort I

A literatura que descreve os resultados das correções cirúrgicas nos tecidos moles é limitada, pois apresenta significativa variação e não oferece conclusões definitivas. O propósito desse artigo é estudar retrospectivamente os efeitos das cirurgias ortognáticas maxilares tipo Le Fort I nos lábios superiores e inferiores de pacientes adultos e discutir os potenciais problemas envolvidos com a metodologia aplicada. Foram estudados 19 pacientes brancos de 19 a 42 anos de idade, sendo 10 homens e 9 mulheres, submetidos a cirurgias maxilares no Centro de Pesquisa e Tratamento das Deformidades Buco-Faciais - CEDEFACE (Araraquara, SP). A grande maioria dos casos apresentou, no mínimo, uma discrepância significativa, seja ântero-posterior ou vertical, reforçando a sua indicação cirúrgica. As alterações nos tecidos moles foram significativas quando as movimentações horizontais ou verticais da base óssea maxilar foram significativas, com uma relação de aproximadamente 0,6:1 entre as alterações ântero-posteriores do lábio superior e a movimentação da base óssea. Alterações verticais na maxila, sem significativas alterações horizontais, não foram suficientes para aumentar verticalmente o lábio superior. Ocorreram alterações ântero-posteriores do lábio inferior em conseqüência do deslocamento anterior e inferior da maxila, o que permitiu um melhor selamento labial. Alterações verticais não foram quantificadas no lábio inferior.

Direct determination of Al, As, Cu, Fe, Mn, and Ni in fuel ethanol by simultaneous GFAAS using integrated platforms pretreated with W-Rh permanent modifier together with Pd plus Mg modifier

A method is proposed for the simultaneous determination of Al, As, Cu, Fe, Mn, and Ni in fuel ethanol by electrothermal atomic absorption spectrometry (ETAAS) using W-Rh permanent modifier together with Pd(NO3)(2) + Mg(NO3)(2) conventional modifier. The integrated platform of a transversely heated graphite atomizer (THGA) was treated with tungsten, followed by rhodium, forming a deposit containing 250 mug W + 200 mug Rh. A 500-muL, volume of fuel ethanol was diluted with 500 muL, of 0.14 mol L-1 HNO3 in an autosampler cup of the spectrometer. Then, 20 muL, of the diluted ethanol was introduced into the pretreated graphite platform followed by the introduction of 5 mug Pd(NO3)(2) + 3 mug Mg(NO3)(2). The injection of this modifier was required to improve arsenic and iron recoveries in fuel ethanol. Calibrations were carried out using multi-element reference solutions prepared in diluted ethanol (1 + 1, v/v) acidified to 0. 14 mol L-1 HNO3. The pyrolysis and atomization temperatures of the heating program were 1200degreesC and 2200degreesC, respectively, which were obtained with multielement reference solutions in acidic diluted ethanol (1 + 1, v/v; 0. 14 mol L-1 HNO3). The characteristic masses for the simultaneous determination in ethanol fuel were 78 pg Al, 33 pg As, 10 pg Cu, 14 pg Fe, 7 pg Mn, and 24 pg Ni. The lifetime of the pretreated tube was about 700 firings. The detection limits (D.L.) were 1.9 mug L-1 Al, 2.9 mug L-1 As, 0.57 mug L-1.Cu, 1.3 mug L-1 Fe, 0.40 mug L-1 Mn, and 1.3 mug L-1 Ni. The relative standard deviations (n = 12) were 4%, 4%, 3%, 1.5%, 1.2%, and 2.2% for Al, As, Cu, Fe, Mn, and Ni, respectively. The recoveries of Al, As, Cu, Fe, Mn, and Ni added to the fuel ethanol samples varied from 81% to 95%, 80% to 98%, 97% to 109%, 85% to 107%, 98% to 106% and 97% to 103%, respectively. Accuracy was checked for the Al, As, Cu, Fe, Mn, and Ni determination in 10 samples purchased at a local gas station in Araraquara-SP City, Brazil. A paired t-test showed that at the 95% confidence level the results were in agreement with those obtained by single-element ETAAS.

EXPOSICAO DE CIRURGIOES-DENTISTAS AO MERCURIO

The professional exposure of dental surgeons to mercury has attracted a great deal of attention from governmental organs and institutions in different countries. Considering that the normal ratio is 10 μg/1000 ml of urine, it was verified from tests that 72.7% of the professionals working in the dental practice in the city of Araraquara (SP) Brazil, show mercury levels above this limit. These results demonstrated the almost complete unawareness of many dentists to mercury and, consequently, precautionary measures were almost nonexistent.

CPITN: time and cost estimates for periodontal prevention and treatment procedures.

The aim of this study was to estimate the necessary time and cost for periodontal prevention and treatment in a working population from sugar and alcohol refineries in Araraquara, SP, Brazil. A stratified sample of 528 employees aged 18-64 from administrative, industrial and agricultural staffs was examined by one examiner, previously trained, according to the community periodontal index of treatment needs (CPITN). The time required for procedures and the cost was extrapolated to the total worker population. The results showed that the estimated time required for periodontal prevention/treatment was 4527 hours. Of this time, 1783 hours were required for oral hygiene instruction, 2531 for scaling, 151 for surgery and 62 for maintenance. The cost would be US $17,655 for hiring a dentist for 8 hours/day to provide oral hygiene instruction, scaling, surgery and maintenance. However, the cost would be US $9,028 for hiring a dentist for 4 hours/day to provide surgery and maintenance and a dental hygienist for 8 hours/day to provide scaling and oral hygiene instruction. Taking into account epidemiologic, technical and economic aspects, the decision relating to manpower should be this second option.

Microbiological quality of ice used to refrigerate foods

Ice used for human consumption or to refrigerate foods can be contaminated with pathogenic microorganisms and may become a vehicle for human infection. To evaluate the microbiological content of commercial ice and ice used to refrigerate fish and seafood, 60 ice samples collected at six different retail points in the city of Araraquara, SP, Brazil, were studied. The following parameters were determined: total plate counts (37° C and 4° C), most probable number (MPN) for total coliforms, fecal coliforms and Escherichia coli, presence of Salmonella spp., Shigella spp., Yersinia spp., E. coli, Vibrio cholerae and Aeromonas spp.. Results suggested poor hygienic conditions of ice production due to the presence of indicator micro-organisms. Fifty strains of E. coli of different serotypes, as well as one Y. enterocolitica biotype 1, serogroup 0:5, 27 and phage type Xz (Ye 1/05,27/Xz) and one Salmonella Enteritidis phage type 1 (PT1) were isolated. Aeromonas spp., Shigella spp. and V. cholerae were not detected. The presence of high numbers of coliforms, heterotrophic indicator micro-organisms and pathogenic strains suggested that commercial ice and ice used to refrigerate fish and seafood may rep resent a potential hazard to the consumer in our community. © 2002 Elsevier Science Ltd.

Evaluation of motivation methods used to obtain appropriate oral hygiene levels in schoolchildren.

The aim of the present study is to assess the behaviour of different motivation methods on levels of oral hygiene among schoolchildren aged from 7 to 9 years in Araraquara, SP, Brazil. The methods tested were: indirect instruction using 'The Smiling Robot' (group I), indirect instruction through class presentation (group II) and direct instruction with macromodels (group III). A control group was also constituted, which received no kind of motivation (group IV). The O'Leary Plaque Index was used as the evaluation method, applied before the instruction and 30 days after application of the different methods. It was noted that the plaque index had not decreased in group IV only. In conclusion, all the motivation methods promoted significant decrease of plaque index and among these methods, the 'The Smiling Robot' was the one that provided the best results.

Isolamento de fungos produtores de enzimas pectinolíticas

Soil samples collected in the campus, UNESP, Araraquara, SP, were employed to isolate and characterize fungi strains with potential pectinolytic enzymes. These enzymes have arisen great interest due to its increasing application in the food industry. Two hundred forty six strains were isolated based on the appearance of colony on PDA medium, morphology (septate mycelia, nonseptate conidiophore, black conidia, and clublike spore-bearing head), after 48 h of growth at 30°C. Strains were selected in solid medium containing pectin citrus as sole carbon source and 0.5% rutenium red. The characterization of pectinolytic production was performed in solid culture and batch fermentation medium containing pectin citrus. The enzyme pectinolytic production was evaluated at 30°C, without agitation in 100 mL of medium containing 2% pectin citrus, 0.2% ammonium sulphate, 0.2% magnesium sulphate, and 0.05% potassium phosphate. The maximum pectinolytic activity (15U/mL) was observed in the medium after Aspergillus sp CFCF-0492 growth, while Aspergillus sp CFCF-CC1 showed the higher level of the final biomass. The pectinolytic activity is more preserved when the fungi-spores were maintained in agar-Czapeck medium.

Avaliação da eficiência dos métodos Direto, COPROTEST e Rugai no diagnóstico da estrongiloidíase

Strongyloidiasis, a relatively common parasitism in tropical and sub-tropical areas, is the result of the infection by the smaller nematode, the Strongyloides stercoralis. Humans can be infected by this parasite, which has in its vital cycle free-life forms of male and female individuals able to live in the ground, and with another step necessary parasitism in the intestinal wall. The diagnostic of the infection is routinely done by the microscopic observation of the larva in stool samples and the high sensibility of urn method over another one allows an trustable and efficient diagnostic. The efficiency of three methods (Direct, COPROTEST and Rugai) used in the Parasitology Sector of the NAC-LACAL in Araraquara (SP) to diagnosis the strongiloidiasis were evaluated. A number of 2346 samples of stool of patients from NAC-LACAL and Nestor Goulart Reis Hospital were analyzed in the period between August and December of 2002. The Rugai Method with an positivity index of 65 % was elected as the most efficient of thee ones.

Estudo da bula de medicamentos: Uma análise da situação

This study was carried out in the city of Araraquara (SP, Brazil), where 1829 people selected randomly from 42 districts were interviewed with regard to their use of medicines, in particular whether and how they read the insert information sheet and the most frequently read items and problems encountered in the text. Surveys were performed in two stages, the first when package inserts were regulated in Brazil by Portaria SVS 110/1997 (Ministry of Health directive) and the second after the new regulation (RDC 140/2003) came into force. Out of 1829 people interviewed, 1597 reported using some medicine. The markedly similar results in both stages of the research pointed to the difficulties encounteved in reading the package inserts, due to the small letters, the obscure language and the massive amount of information. This paper shows that package inserts of medicines need to be simpler, so the patients have an idea of the importance of the medicine and are able to realize soon any problem that might appear due to the use of the medicine and what action they should take. Furthermore, it will be helpful to the evaluation of the package inserts of medicines, elaborated in conformity with RDC 140, if they work effectively as a source of information and guidance for the patient are not simply given a new layout, while maintaining items that impede their understanding and use.

Avaliação de diferentes métodos no diagnóstico laboratorial de Giardia lamblia

The protozoan parasite Giardia lamblia is responsible for a common intestinal infection in all regions of the world. In this study, four laboratory tests were evaluated for diagnostic reproducibility in the detection of this infection: Coprotest®, Direct modified method, Faust method and iron-hematoxylin staining. Positive diagnoses were tested for association with factors such as the age group and gender of the subject and the month when the sample was taken. Feces of 200 children in the Araraquara region (SP, Brazil) were examined by all four methods and the results compared. G. lamblia was found to be the most frequent parasite and 8.0% of the children showed giardiasis. There was no apparent correlation with gender, but most of the parasites were found in three- to five-year-olds. The highest frequency of infection occurred in January. The most reliable diagnostic results for G. lamblia were achieved by combining at least two methods of good reproducibility, i.e. Coprotest-Faust, Direct-Faust or Coprotest-Direct (A > 0.81).

Intraspecific variability of dihydrochalcone, chromenes and benzoic acid derivatives in leaves of Piper aduncum L. (Piperaceae)

Chemical analysis carried out in leaves of 18 specimens of Piper aduncum L. (Piperaceae) occurring at Ripasa Reserve, Araraquara, SP, Brazil indicated two distinct populations when investigated over a period of 14 months (January 2000 to February 2001) and then submitted to cluster analysis. The two groups were characterized by accumulation of prenylated benzoic acids, chromenes and dihydrochalcone, respectively. A total of seven compounds were identified by HPLC analysis and compared with standards including two prenylated benzoic acid [aduncumene (1) and 3-(3′-7′-dimethyl-2′-6′-octadienyl)- 4-methoxy-benzoic acid (5)], four chromenes [methyl 2,2-dimethyl-8-(3′- methyl-2′-butenyl)-2H-1-chromene-6-carboxylate (4), methyl 2,2-dimethyl-2H-1-chromene-6-carboxylate (2b), methyl 8-hydroxy-2,2-dimethyl-2H- 1-chromene-6-carboxylate (3) and 2,2-dimethyl-2H-1-chromene-6-carboxylic acid (2a)] and one dihydrochalcone [2′,6′-dihydroxy-4′-methoxy- dihydrochalcone (6)]. © 2009 Academic Journals.

A ótica do usuário na avaliação da qualidade do programa de atenção odontológica à gestante

Objective: To evaluate the pregnant women's perception of the FOA-UNESP's Pregnant Women Dental Care Program (Araraquara, SP, Brazil). Method: The sample included 75 pregnant women and used a questionnaire with 16 closed questions, containing variables grouped in the following categories: the didactic-psychological meetings, clinical treatment, professional's profile, clinical facility, fear/confidence in the treatment, and learning. Except for the variables fear/confidence in the treatment and learning, to which 'yes' or 'no' answers were attributed, the remaining variables were attributed answers varying from weak to excellent. The questionnaire pretested in a pilot-study and applied after informed consent was obtained from all pregnant women treated between 2005 and 2006. Results: Most women rated as excellent the information addressed during the didactic-psychological meetings (81.1%), the clinical treatment (90.6%), the professional as to personal appearance, kindness and attention (88.7%, 96.2% and 90.6%, respectively), and the clinical facility as to cleanness, ventilation and comfort (92.5%, 86.8% and 90.6%, respectively). Most of them stated to feel confident (96.2%) and have no fear (86.8%) during the treatment and also affirmed having learned new information in the didactic-psychological meetings of the program (92.5%). Conclusion: The services and actions developed in the program have reached successful outcomes, providing health to the pregnant women and their forthcoming babies.

Escala de ansiedade odontológica: Reprodutibilidade das respostas dadas em entrevistas telefônicas e pessoais

Objective: To estimate the intra-examiner reproducibility of the Dental Anxiety Scale (DAS) when applied by phone and personal interviews and to evaluate the association between the level of anxiety and the factors of interest. Method: The participants were 50 individuals (n=38 females) with mean age of 23.9±8.9 years, living in the city of Araraquara, SP, Brazil. The volunteers answered the DAS by means of two phone interviews with one-week interval between them. After 30 days, the DAS was applied to the same participants by means of personal interviews at two moments with one-week interval between them. Intra-examiner reproducibility was determined using Kappa (K) statistics by point and by confidence interval. Results: The intra-examiner agreement for the level of anxiety was 0.82 (0.75-0.90) for the phone interview and 0.69 (0.60-0.79) for the personal interview. Two of the DAS questions presented statistically significant difference in the intra-examiner reproducibility, with better agreement for the answers given by the participants during phone calls. The prevalence of dental anxiety in the sample was 92.0%, in such a way that 70.0%, 18.0% and 4.0% of them presented low, moderate and exacerbated anxiety. Conclusion: The classification of the individuals according to the anxiety level performed by means of phone and personal interviews presented statistically similar agreement. However, there was better agreement with phone calls for the questions referring to anxiety in the dental office's waiting room and during preparation of the motor for use in the dental treatment.
