COMPARACAO ENTRE MEDICAMENTOS ORAIS ATRAVES DAS TAXAS SERICAS DE GLICOSE, AMILASE, ACIDOS GRAXOS LIVRES E LIPOPROTEINAS DE ALTA DENSIDADE (HDL-COLESTEROL) NOS DIABETICOS DE AMBOS OS SEXOS, DA REGIAO DE ARARAQUARA, NAO-DEPENDENTES DE INSULINA

A study was carried out, on both sexes, to determine the effects of chlorpropamide (DIABINESE) and glibenclamide (DAONIL) on patients with Type II diabetes using as metabolic parameters the following serum: glucose, amilase, high density lipoprotein cholesterol, free fatty acids. The results indicated that both drugs were potentially similar in relation to glycemia, high density lipoprotein cholesterol, and free fatty acids, in both sexes. Chlorpropamide was significantly more effective in reducing amilase activity in male diabetics than glibenclamide. The above mentioned hypoglycemiants did not reduce glycemia to basic levels in either masculine or feminine groups of diabetics.

ANALISE ANTIGENICA DE PROTEASES DE DIFERENTES CEPAS DE TRICHOMONAS VAGINALIS ISOLADAS DE PACIENTES DA REGIAO DE ARARAQUARA, SP, BRASIL

Trichomonas vaginalis is the flagellate that causes trichomonadiasis, a sexually transmitted disease. Immunological methods have been proposed for the study of antigenic characterization using strains isolated from different patients. This work compares protease profiles from the different strains using gelatin containing polyacrylamide gels to analyse the protease activity. High molecular weight proteases (20 to 100 kDa) were found on gels showing quantitative differences. Human IgG antiproteases were detected by immunoblotting using the same extracts. These proteases could be related with T. vaginalis pathogenesis.

CONDICOES BACTERIOLOGICAS DE LEITE CRU E DE LEITE PASTEURIZADO NA REGIAO DE ARARAQUARA, SP, BRASIL

Milk can be an important spreading vehicle of pathogenic agents mainly for young children who are an important group of milk consumers. 135 milk samples (77 of raw milk and 58 of pasteurized milk) were analysed in order to verify the number of heterotrophic bacteria, of Staphylococcus aureus and of total coliforms, as well as to determine presence of Salmonella, Shigella, enteropathogenic Escherichia coli (EPEC) and enteroinvasive Escherichia coli (EIEC). The results were negative for Salmonella, Shigella and EIEC. EPEC serotypes 0:28, 0:111 and 0:55 were isolated in 4 of raw milk samples. The heterotrophic bacteria was found in counts over 30.000 UFC/mL in 91%, 25% and 68,75% respectively of raw milk, milk grade B and grade C. Counts over 30.000 coliforms/mL were found in 70,13%, 6,25% and 6,24% of the raw milk, B and C, respectively. 32,40% of the raw milk had counts of S. aureus over 3.000 UFC/mL.

Prevalence and severity of caries in 3-12-year-old children from three districts with different fluoridation histories in Araraquara, SP, Brazil

Objective: To determine the prevalence and severity of caries in 3-12-year-old children in three districts of the city of Araraquara, Design: An epidemiological survey was carried out by trained and calibrated examiners in 1995 and 1996, using the WHO diagnostic criteria. Setting: Two districts, Araraquara and Vila Xavier had been fluoridated since 1963 and one, Gavião Peixoto, since 1994. Subjects: The study included 1,191 children from Araraquara, 653 from Vila Xavier and 652 from Gavião Peixoto. Outcome measures: Prevalence of caries, dmft, dmfs, DMFT and DMFS indices. Results: Results showed moderate caries experience in all three districts. Differences between districts in relation to fluoridation history were particularly obvious in primary teeth. In 3-4-year-old children, one third of those in Araraquara and Vila Xavier had some caries experience compared to 58% in Gavião Peixoto. In permanent teeth, 20% or less of the mean DMFT was made up of untreated decay in Araraquara and Vila Xavier whereas in Gaviao Peixoto it made up between 50 and 57% of values in 7-12-year-old children. Conclusions: The prevalence and severity of caries was lower in dentitions of children from the districts fluoridated since 1963. Improvements are likely in the future in Gaviao Peixoto as the benefit of fluoridation continues but additional means of promoting oral health are needed in all three districts.

Measuring fluoride concentration in mineral waters in the Araraquara region, Brazil

It has been shown that people of all ages can benefit from the topical and systemic effects of water fluoridation. However, the increase in consumption of bottled water, either to substitute for or supplement consumption of water from public sources, has implications for safe fluoride supplementation. Taking that into consideration, in 1995 we analyzed the fluoride content in 31 commercial brands of mineral water in the region of Araraquara, state of Sao Paulo, Brazil. Fluoride concentration as determined by our analysis was compared to the concentration of fluoride specified on each label. Only 25% of the products studied listed the fluoride concentration on their labels. In addition, among 31 mineral water brands, 26 listed the date when the chemical analysis to determine chemical composition had been performed. Of these, 20 had not been put through the annual chemical analysis determined by Brazilian law. Based on these results, if the mineral waters tested had been the only source of drinking water, fluoride supplementation would have been necessary in 69% of the samples analyzed. In the case of children up to 6 years of age who use products containing fluoride, such as topical gels, mouthwashes or toothpastes, supplementation should be recommended only if commercially bottled water is the only source of water used, not only for drinking but for cooking as well.

Changes in periodontal conditions of children and adolescents from Araraquara, Brazil: 1995-1998.

The aim of this study was to compare the periodontal conditions in 7-15-year-olds from Araraquara, SP, Brazil in 1998 with data from 1995. A systematic random sample was drawn from the population of children and adolescents enrolled in all public schools in 1998. The survey was conducted by trained examiners using the CPITN and WHO diagnostic criteria. Results showed an increase in the percentage of students of all ages with healthy periodontal conditions (from 14% in 1995 to 33% in 1998; p < 0.01). An increase in the mean number of healthy sextants (from 3.2 to 4.4; p < 0.0001), a decrease in the mean number of bleeding sextants (from 2.5 to 1.2; p < 0.0001) and no difference in the mean number of sextants with calculus were also observed. At the age of 15, 54% of the students had 5-6 healthy sextants in 1998 compared to 19% in 1995 (p < 0.01). Despite the improvement observed in the periodontal conditions, efforts must be increased in order to achieve the WHO goal for the year 2010 of no more than one sextant affected by bleeding or calculus at the age of 15.

Microbiota fúngica de um prédio com laboratórios da região de Araraquara-SP

From September 2000 to January 2001, airborne fungi were isolated from the building of the Clinical Analyses laboratories, including its didactic and research rooms, in Araraquara São Paulo State, Brazil, by using Andersen, MAS-100® (MERCK) machine, with Sabouraud chloramphenicol medium. After 5 days of incubation at 25°C, the colonies of the fungi were counted, resulting in the identification of 21 taxa. Cladophialophora spp. was the most isolated in internal and external environments as well, followed by Penicillium spp. and Mycelia spp. In accordance with the resolution n° 9, January 2003 (ANVISA), fungi considered unacceptable were found in nine internal environments and one of these presented the amount of fungi above of the acceptable limit. Among the obtained fungi, at least 16 taxa were reported as opportunistic, nine were related to plant diseases and seven were associated to allergy problems.

Epidemiologia das dermatofitoses em instituições públicas da região de Araraquara - SP

Dermatophytosis on skin, hair and nails are the most common infectious process in the world. A total of 94 individuals from Public Institutions from the city of Araraquara - Sao Paulo/Brazil, with suspected of dermatophytic lesions were examined in order to determine the incidence and etiology of dermatophytosis. 105 specimens were collected from August to December of 2001 in the Mycology Laboratory of the Faculdade de Ciências Farmacêuticas. It was observed that 47 samples were positive for dermatophytes. Trichophyton rubrum was the prevalent specie (59.6%), followed by Microsporum canis (17%), T. tonsurans (10.6%), T. mentagrophytes (8.5%) and Epidermophyton floccosum (4.3%). T. rubrum was the most frequent in interdigital lesions (81.5%) and M. canis was the main dermatophyte involved in scalp lesions (58.3%). Therefore, it was observed a predominance of antropophilic and zoophilic species, respectively. These results are in agreement with statistical data from South and Southeast regions of Brazil, as well as from other parts of the world in which these fungi were the most frequently isolates from tinea pedis and tinea capitis. In this study, it was also observed a high percentage of T. tonsurans (41.7%) in tinea capitis and this result was different from the statistical data collected until now in our region.

Antibiótico antifungico produzido por um estreptomiceto da região de Araraquara

With the significant increase in the incidence of invasive fungal infections during the last decade, mainly in patients with cancer, AIDS and other hospitalized patients who stay for long periods in intensive care units, there is an urgent need to screen for new antifungal agents possessing some advantages over known ones. This article reports a search in the field for a microorganism producing antibacterial and antifungal substances. Strains from soil samples collected in the region of Araraquara, Brazil, were isolated and analyzed for their antimicrobial potential against standard microorganisms (fungi Candida albicans and Aspergillus oryzae and bacteria Staphylococcus aureus and Escherichia coli). Out of the 64 strains isolated, 34 produced detectable antimicrobial activity. The streptomycete strain Ar4014 was chosen for further study, owing to its good antimicrobial activity against Candida albicans. Two of the fermentation media tested, 608-K and 602-B, were found to be best for the production and extraction of the antibiotic from Ar4014. After chromatographic separation of the crude extract on a silica column, the active fractions obtained showed UV-VIS absorption peaks characteristic of normal pentaenic antibiotics. The antibiotic was provisionally designated Ara 4014-75.

Qualidade dos medicamentos contendo dipirona encontrados nas residências de Araraquara e sua relação com a atenção farmacêutica

Many studies had described the morbi-mortality related to medicines. As for the strategies to reduce the possible risks for medicine therapy is very important to readvise the pharmaceutical activity, once the pharmacist has potential for constitute an essential part for the solution of problems related to the utilization of medicines. The purpose of this work was to demonstrate that the therapeutic subdosage and the microbiological contamination may be directly involved with the inappropriate manipulation of medicines stored in residences. Liquid dosage forms containing dipyrone market in Brazil and stored at homes in Araraquara (SP) were analyzed regarding quantitative and microbiological analysis. Only in 57% from 128 samples analyzed the drug quantity was in accordance. Moreover, 26.2% from 128 samples analyzed presented S. aureus, E. coli and Salmonella sp. These results demonstrated clear reduction in their quality, as well as the presence of molds and/or bacteria in some medicines that still agreed with the expirations dates, showing the importance of the pharmacist in advising the correct use and store of medicines.

Acesso a medicamentos essenciais em farmácias e drogarias do Município de Araraquara

A survey to determine the availability of 20 essential medicines for the diseases with highest prevalence in primary health care was conducted in the city of Araraquara. The presence and the price of these medicines in private sector pharmacies and drugstores of the city were recorded. Two forms, recommended by the WHO, were used in the survey, one for availability and the other for prices. The drugs most commonly available in pharmacies and drugstores were: propranolol (90.5%), captopril (96%) and ranitidine (96%), while the least available were ferrous sulfate (27%), beclomethasone (33.8%) and ibuprofen (41.9%). The drugs that showed the greatest variation among the prices charged were: propranolol (97.1%), hydrochlorothiazide (96.4%) and glibenclamide (95.0%), while the least variable were salbutamol (30.8%) and trimethoprim-sulfamethoxazole (30.2%). Generic drugs, which were half (10) of those assessed, had the lowest prices. The indicators of access, referring to the ability of patients to acquire drugs for the treatment of major diseases at the primary health care level, showed that no establishment stocked all 20 essential drugs and that wide variations existed in their prices, undermining their availability to drug users, whose only sources are pharmacies and drugstores. These data demonstrate the importance of the popular pharmacy to improve the access to medicines, by lowering the cost and increasing the availability of the items selected for the National List of Essential Drugs (RENAME).

Atitudes em relação à Bioestatística de discentes e docentes da Faculdade de Ciências Farmacêuticas de Araraquara-UNESP

In this study, the attitudes of students and teachers at the Faculty of Pharmaceutical Sciences of Araraquara (UNESP University) towards Biostatistics were assessed. The Survey of Attitudes Toward Statistics (SATS) scale was used as the measuring instrument. The reproducibility of the scale was estimated by Cohen's Kappa (κ) coefficient with linear weighting and its internal consistency by Cronbach's alpha coefficient (α). The individuals were first placed in two groups, according to their positive or negative attitude toward Statistics; then, the association of their attitude with the variables of interest was tested by the chi-squared (χ 2) test at a significance level of 5%. The sample consisted of 272 undergraduate students, 83 graduate students and 24 teachers, predominantly female (78.2%). Among the students, 67.5% participated in the scientific research initial training program. Reproducibility and internal consistency of the scale were adequate (κ=0.7093; α=0.9334). Most of the subjects (74.4%) had a positive attitude toward Statistics. Significant association was found between attitude and functional activity (p=0.0204), the course taken (p=0.0316) and effort (p=0.0002). Thus, it was concluded that the great majority of the participants had a positive attitude towards Biostatistics and that undergraduate students and those who reported good performance in Biostatistics showed a significantly higher proportion of positive attitude than the other students.

Análise das prevalências de doenças detectadas pelo programa nacional de triagem neonatal no município de Araraquara no ano de 2009

The National Neonatal Screening Program (NNSP) set up in all Brazil, aims, through planned phases of local implementation, to detect diseases such as phenylketonuria, congenital hypothyroidism, hemoglobinopathies and cystic fibrosis. The aim of this study was to assess, through a cross-sectional observational study, the prevalence of the diseases detected by the NNSP in the city of Araraquara, in records issued by the São Paulo APAE laboratory in the period between April and December 2009.The results show that Araraquara had a prevalence of phenylketonuria and congenital hypothyroidism 0.06% above the national averages of 0.01% and 0.03% respectively. With respect to hemoglobinopathies, the prevalence of sickle cell trait was 2.15% below the national average of 2.6%. The prevalence of Hb C in the city was 0.57%, similar to national values reported in the literature. Confirmed Hb Bart's had a prevalence of 0.13% in Araraquara, below the average of 0.38% for the surrounding region. The neonatal screening by heel-prick test and counseling for caregivers are important factors in reducing morbidity related to the evolution of these diseases.
