Reação de microimunodifusão em gel de ágar no diagnóstico sorológico da paracoccidioidomicose

Utilizou-se técnica de microimunodifusão dupla em gel de ágar para a medida quali e quantitativa de anticorpos circulantes anti - P. brasiliensis, comparando-se os resultados com o macrométodo. Todos os 103 soros de pacientes portadores de paracoccidioidomicose foram positivos no micrométodo contra 87% de positividade no macrométodo. Os 83 soros de pacientes sem paracoccidioidomicose foram negativos em ambas as reações. Os títulos dos soros positivos tenderam a ser mais elevados no micrométodo, que forneceu bandas de precipitação mais nítidas e fáceis de serem lidas. O micrométodo é de realização simples, utiliza pequena quantidade de material e possibilita o teste simultâneo de 102 soros. Acreditamos que ele poderá substituir o macrométodo, especialmente em laboratórios de grande rotina sorológica.

Consumo de medicamentos por idosos segundo prescrição médica em Jaú-SP

This study was carried out in order to identify the interactions that occur most often between prescribed drugs as they are taken by elderly patients attending municipal public health centers in the city of Jaú, São Paulo State, Brazil. It is known that older people frequently have to live with chronic health problems, which oblige them to use the health service a great deal and to consume large quantities of medicines. When concomitant diseases are present, and polytherapy is being applied, the likelihood of adverse reactions and interactions between drugs increases. The population under study consisted of 148 persons aged 65 or more who frequented the pharmacy at the Núcleo de Gestão Assistencial (Municipal Health Centre, NGA25) in Jaú, between August and December 2004. Data were collected from medical prescriptions, the independent variables being the age and sex of the patient. For each patient, the pharmacological classes of drugs taken and drug-drug interactions were recorded. It was found that the mean numbers of drugs consumed were 3.8 among women and 3.9 among men. In terms of age, the highest number of drugs (4.2) was used in the group aged 75 to 84 years. The most frequently prescribed classes, in decreasing order, were: antihypertensives, 25.0%, heart drugs, 15.5%, diuretics, and anti-diabetic drugs, 10.7%. It was concluded that the classes most involved in drug-drug interactions were heart drugs, diuretics and antihypertensives. The most problematic active constituents were digoxin, amiodarone, frusemide, captopril, propranolol and nifedipine.

Fatores relacionados à adesão das drogarias e farmácias de Tatuí-SP no projeto Farmácias Notificadoras

Pharmacovigilance is accomplished by voluntary notification of suspected adverse reactions, medication errors, and deviations from quality, by users and health professionals, through the filling in of forms that are sent to a data bank. To broaden the sources of notifications, the National Health Surveillance Agency (ANVISA), in partnership with the Regional Pharmacy Council (CRF) and Center for Health Surveillance (CVS) of each state, introduced the scheme of Notifying Pharmacies. The present study was aimed at determining the factors influencing the decision of drugstores and private pharmacies in Tatuí/SP in 2007, to join this project A descriptive, observational survey of knowledge, attitude and practice (KAP) was applied to volunteer pharmacists in the town. The results showed that the professionals are awave of pharmacovigilance, (95.24%) and have attitude (95.24%). However, practice is limited (6.0%). Based on this information we concluded that the low support of the project was due to lack of time, interest and no information about the benefits to society of such activity and a lack of support from the pharmacists' organizations. This situation is expected to change with the current introduction of a professional profile, the fusion of professional bodies and the promotion of social awareness on pharmacovigilance.

Ensaios biológicos para avaliação de segurança de produtos cosméticos

Despite efforts to the contrary, some cosmetic products can cause undesirable side effects in the users. These may often be due to individual factors or inappropriate use of the product. Thus, biological assays to assess the safety of a new cosmetic must precede its being placed on the market. Historically, these tests have always been carried out in vivo, in animals, since such tests can be used to evaluate many of the potential risks, such as irritation, allergy or systemic effects; but, recently, some research centers have been adopting in vitro alternatives, in order to replace the animal tests. This review emphasizes the need to employ biological assays to test the safety of cosmetic products, and reviews the main in vivo and in vitro tests used, focusing on the need to develop and use alternatives to the in vivo assays of product safety, so as to offer the consumers the maximum safety with the least possible risk, while ensuring the best conditions of use of the product.

Estudo da segurança de cosméticos: Presente e futuro

Cosmetics have been used since ancient times and, recently, their consumption has increased greatly in many countries, including brazil, which is the third largest consumer market in the world. Thus, concern for the safety and efficacy of these products should be heightened, even though these products are rarely related to adverse reactions that damage the health. Brazilian law requires manufacturers to subject their products to safety testing, to assess the possible reactions that could be caused by them (irritation, sensitization, systemic effects). To this end, in general, animals have been used as the experimental model, but this practice is being increasingly controlled, so that the scientific community is looking for alternative tests that do not require experimental in vivo models. Thus, this review aims to describe the main biological assays used to assess the safety of cosmetics, as well as in vitro assays that can replace them.
