RESUMO
AIM: This prospective clinical study evaluated the incidence of instrument fracture observed after single-file root canal treatment of molars using WaveOne Gold instruments. METHODOLOGY: Three standardized, experienced and calibrated specialists treated 750 maxillary and mandibular molars with curvatures less than 45° (2691 root canals) over a 12-month period. All the treatments were performed in a single session. A total of 1104 WaveOne Gold instruments were used, including 38 small, 750 primary, 228 medium and 88 large instruments. Intracanal procedures were performed according to the manufacturer's recommendations, and each instrument was used in a single clinical case. The instruments were examined after their removal from the canal, under an operating microscope at 8× magnification. RESULTS: No fractures were observed in any of the 1104 instruments used. CONCLUSIONS: No fractures of WaveOne Gold reciprocating instruments occurred during root canal preparations performed in maxillary and mandibular molars with curvatures less than 45° when used strictly according to the manufacturer's recommendations and applied in a single clinical case.

Idosos utilizam elevado número de medicamentos, apresentando alto potencial para desenvolver interações medicamentosas. Objetivou-se verificar o perfil de utilização de medicamentos e conhecer possíveis interações medicamentosas em idosos acompanhados pelo Programa de Atenção ao Idoso (PAI) da Unijuí. Os dados foram coletados em julho de 2009. Classificaramse os medicamentos no sistema Anatomical Therapeutic Chemical e possibilidades de interações segundo Drug Interaction Facts. De março/2008 até julho/2009 o PAI atendeu 31 idosos, estando 16 em acompanhamento, os quais apresentaram média de 78,4 ± 6,8 anos e utilizaram 83 medicamentos, com média de 5,2 ± 3,7/ idoso. Os fármacos mais prevalentes foram os que atuam no aparelho cardiovascular, no sistema nervoso e para o trato alimentar e metabolismo. Verificaram-se 36 possíveis interações entre 9 pacientes, com média de 4/idoso. O fármaco mais envolvido foi digoxina. Quanto a classificação, 4 apresentaram nível de significância 1, dez nível 2, cinco nível 3, sete nível 4 e dez nível 5. O número de possíveis interações verificadas foi expressivo, entretanto nem todos os idosos apresentarão reações relacionadas às interações, mas apresentaram o risco. Portanto, é importante que prescritores conheçam a influência de um fármaco sobre outro. Seria necessário treinamento intensivo para intervenção farmacêutica, sendo o relacionamento com o médico indispensável.
Elderly people take a large number of medicines, entailing a high risk of developing drug interactions. The aim was to study the profile of medicines prescribed and the possible drug interactions in the public Elderly Care Program (PAI) run at Unijuí, a university in south Brazil. The data were collected in July 2009. The Anatomical Therapeutic Chemical (ATC) Classification System was used to classify medicines, while the potential interactions were classified with the aid of Drug Interaction Facts. Between March 2008 and July 2008, the PAI attended 31 elderly patients, of whom 16 were monitored, with a mean age of 78.4 ± 6.8 years. This group received 83 medicines, making an average of 5.2 ± 3.7 medicines/patient. The most prevalent drugs were those acting on the cardiovascular system, nervous system, digestive tract and metabolism. There were 36 possible interactions in 9 patients, an average of 4 interactions per patient. The drug most frequently involved was digoxin. The interactions were classified as follows: 4 at level 1, 10 at level 2, 5 at level 3, 7 at level 4 and 10 at level 5. This number of possible interactions is considerable; although not all elderly patients show the effects of the drug interactions, they do run the risk. Therefore, it is highly important that prescribers are familiar with the drug interactions. For the pharmacist to help the patient, intensive training for pharmaceutical intervention and a good relationship with the doctor are indispensable.

O objetivo do estudo foi determinar a prevalência da farmácia caseira, conhecer os medicamentos que a compõem, os locais destinados ao armazenamento e descarte. Realizou-se estudo transversal junto a famílias do bairro Luiz Fogliatto, Ijuí, RS, cadastradas na Unidade Básica de Saúde deste bairro. As entrevistas foram realizadas nos domicílios de junho a agosto de 2008. Dentre 640 famílias, foram visitadas 321, das quais 91,59% possuíam medicamentos em casa. Encontraram-se 1.234 medicamentos, com predomínio dos atuantes no sistema nervoso (27,28%). A cozinha foi o principal local de armazenamento. Foram encontrados medicamentos vencidos em 17 residências, predominando o descarte no lixo (56,87%). Não foi encontrada legislação que regulamente o descarte de medicamentos em nível domiciliar. O conhecimento quanto ao tema abordado ainda é restrito e impede sua adequada organização em nível domiciliar. O farmacêutico deve orientar quanto ao armazenamento e descarte, capacitando os Agentes Comunitários de Saúde, visando evitar a exposição da população a riscos, assim como a contaminação do meio ambiente.
The aim of this study was to determine the prevalence of household stocks of medicine, to know which medicines are stocked in the home and the places where they are stored and discarded. A cross-sectional survey was conducted with families from the Luiz Fogliatto neighborhood of Ijuí city (RS), registered at the neighborhood Health Service clinic. The interviews were carried out at home in June to August, 2008. There are 640 families in the neighborhood and 321 were visited, of which 91.59% had some medicines at home. In all, 1234 medicines were found, mostly those that act on the nervous system (27.28%). The kitchen was the main place used to store medicines. Expired medicines were found in 17 residences, and the main disposal route was in the common garbage (56.87%). No legislation was found that regulates the disposal of household medicines. Knowledge on storage and disposal of medicines is restricted and does not suffice for its proper organization at home. The pharmacist should educate the patient about storage and disposal and capacitate Community Health Agents, in order to avoid exposure of the public to risks, as well as contamination of the environment.
