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.

Importância de Yersinia enterocolitica em microbiologia médica

Y. enterocolitica is a human invasive enteropathogen which causes a number of intestinal and extraintestinal clinical symptoms of various degrees of severity, ranging from mild gastroenteritis to mesenteric lymphadenitis, which mimics appendicitis and in rare cases can evolve to septicemia. Infection by Y. enterocolitica can also lead to post-infection immunological sequelae including arthritis, erythema nodosum and glomerulonephritis. Pathogenic Y. enterocolitica strains have traditionally been linked to specific biotypes and serogroups and associated to a variety of phenotypic characteristics related to virulence. Molecular genetics studies have pointed to the importance of the pYV virulence plasmid, which encodes various virulence genes, as well that of specific chromosomal virulence genes, in determining the pathogenesis of this bacterium. Intestinal infections by Y. enterocolitica are mostly self-limiting and usually do not need an antibiotic treatment. The occurrence of this microorganism is not as frequently described in Brazil as it is in other countries, such as Japan, USA and many European countries. This review focuses on the general characteristics, pathogenesis, clinical symptoms, virulence characteristics, treatment and antibiotic susceptibility of Yersinia enterocolitica strains isolated in Brazil and around the world.

Consulta de enfermagem ao portador de Hanseníase: proposta de um instrumento para aplicação do processo de enfermagem.

This study aimed at reporting the experience of nursing consultation for leprosy patients performed at a university primary health care unit in inner São Paulo state as well as at presenting the instrument used. This activity is performed by two nurses who have worked in the program for over two decades and have thus become experienced in providing care to this type of patient. The effectiveness of instruments is evaluated as concerns form and content, thus enabling the assessment of actual health care needs based on an expanded analysis of the health-disease process. With this proposal, it is expected that nurses' action will be facilitated in the implementation of procedures aiming at comprehensive care.

Efeitos sedativo e cardiorrespiratório da administração da metadona, isoladamente ou em associação à acepromazina ou xilazina, em gatos

Six cats weighting 3.3±0.3 kg were randomly allocated to 6 treatments, with at least one-week intervals. The cats received intramuscular administration of physiological saline (control), methadone (0.3 mg/ kg), acepromazine (0,1 mg/kg), xylazine (1.0 mg/kg), acepromazine (0.05 mg/kg) plus methadone (0.3 mg/kg) or xylazine (0.5 mg/kg) plus methadone (0.3 mg/kg). Heart rate (HR), respiratory rate (RR), indirect systolic arterial pressure (SAP), rectal temperature, sedation score and pedal withdrawal reflex were evaluated before (baseline) and at selected intervals after treatment administration for 90 minutes. Respiratory rate, HR and rectal temperature decreased in cats given xylazine or xylazine plus methadone. In 1 out of 6 cats given xylazine and 2 out of 6 cats given xylazine/methadone, pedal withdrawal reflex was absent. In cats given 0.1 mg/kg of acepromazine, SAP decreased compared to baseline. Sedation scores were greater in cats given xylazine or xylazine plus methadone. Methadone alone or in combination with acepromazine did not produce a satisfactory degree of sedation and resulted in signs of excitement in some of the cats. Methadone alone or combination with acepromazine was not considered an effective protocol when moderate to deep sedation is required in cats. Methadone in combination with xylazine produces moderate to deep sedation, being this effect comparable to that achieved with a higher dose of xylazine alone.

Administração pública: O pacto pela saúde como uma nova estratégia de racionalização das ações e serviços em saúde no Brasil

The health pact arises in the Brazilian scene after a number of attempts for the improvement of the Unified Health System (SUS), so as to consolidate social equity. In this perspective, this paper discusses the pact using documental analysis, in order to help the public administration process in Brazil. This new policy, still in the initial phase of implementation, is a unique reality and highly feasible for the improvement of national practices in public health. Its performance is intimately related to overcoming the political barriers inherent to each rank of the administration.

Sistemas biodegradáveis contendo acetato de prednisolona para administração orbitária

Purpose: The present study aimed to evaluate an injectable extended-release formulation of prednisolone acetate (PA) for orbital administration. Methods: Microspheres (MEs) of poly-ε-caprolactone (PCL) containing PA were developed by the method of solvent evaporation. The MEs obtained were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), encapsulation efficiency and in vitro release profile. The in vivo release profile was evaluated in rabbits after periocular injection of an aqueous suspension of MEs. The local biocompatibility of the system was verified by histopathologic analysis of the deployment region. Results: After MEs preparation, morphological analysis by SEM showed the feasibility of the employed method. The content of PA encapsulated was 43 ± 7% and can be considered as satisfactory. The system characterization by DSC technique, in addition to confirm the system stability, did not indicate the existence of interaction between the drug and the polymer. The in vitro release study showed the prolonged-release features of the developed system. Preliminary in vivo study showed the absence of local toxicity and confirmed the prolonged release profile of PA from MEs, suggesting the viability of the developed system for the treatment of orbital inflammatory diseases. Conclusion: The results obtained in this work are relevant and accredit the system developed as a possible alternative to the treatment of inflammatory orbitopathy.
