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.

Cytogenetic characterization of the silverside fish Odontesthes regia (Humboldt, 1833) (Teleostei: Atheriniformes: Atherinopsidae) from Iquique, Chile

This paper describes the karyotype of Odontesthes regia by means of Giemsa staining, C-banding, to reveal the distribution of the constitutive heterochromatin, and by Ag-staining and fluorescent in situ hybridization (FISH), to locate ribosomal genes (rDNA). The chromosome diploid modal count in the species was 2n = 48. The karyotype is composed of one submetacentric pair (pair 1), 16 subtelocentric pairs (pairs 2 to 17), and 7 acrocentric pairs (pairs 18 to 24). With the exception of pair 1 it was not possible to classify the homologous chromosomes accurately because differences in chromosome size were too slight between adjacent pairs. The distribution of C-banded heterochromatin allowed for a more accurate matching of the majority of chromosomes of the subtelocentric series. Silver staining of metaphase spreads allowed for the identification of Nucleolus Organizer Regions (Ag-NOR) on pair 1. FISH experiments showed that 18S rDNA sequences were located, as expected, in the same chromosome pair identified as the Ag-NOR-bearing one.

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.

Análise das propagandas dos medicamentos isentos de prescrição veiculadas em revistas para prescritores na área médica

This article presents an analysis of the quality of advertisements for over-the-counter (OTC) drugs addressed to the medical profession, based on the new Anvisa resolution RDC 96 (17/12/2008). For this analysis, 16 volumes of the Brazilian Journal of Medicine (RBM) were collected, from August 2009 to December 2010. To investigate the quality of the adverts, we prepared a questionnaire divided into three parts. In total, 160 advertisements were found, of which 27 were related to drugs exempt from prescription, from 9 laboratories. It was observed that none of the advertisements complied fully with the new rules, as required by legislation (RDC 96/08), with violations ranging from identification of the advert to prohibitions of human figures and subjective messages. Therefore, it was concluded that there is a need to implement more effective monitoring, so as to improve the quality of the adverts, so they can be used as a reliable source of information and update by prescribers.

Carcinoma de lábio com prognóstico sombrio devido conduta médica inadequada

The Squamous Cell Carcinoma is what more happens among the oral cancers, being considered sweats incidence in more than 90%. As important prognostic factor competes the early diagnosis and the immediate institution of the treatment, that it can involve radiotherapy and chemotherapy besides the surgery. The initial lesions don’t offer great diagnostic difficulties and now complemental laboratory exams define the diagnosis quickly, In the present report, the initial medical conduct was inadequate, with incomplete interpretation of the laboratorial result and adoption of inadequate therapeutic conduct, what resulted in constant evolution of the lesion. The patient came to the consultation with that medical history, after six months of the first attendance accomplished in another center. To the physical exam, infiltrative ulcerated lesion was observed in the lower lip, with having accentuated tissue loss superficially. The patient accused spontaneous pain and she did use an ointment, recommended six months ago for occasion of the first attendance. As diagnostic conduct was indicated the accomplishment of cytology and biopsy, being defined the diagnosis of Squamous Cell Carcinoma. The patient was immediately guided to the medical service of its municipal district for manegement of the specialized oncologic treatment. The patient was submitted the surgery followed by radiotherapy, being verified involvement of another structures by contiguity. Now, the patient meets abed, without viable perspectives of cure. The present report emphasizes the importance of the clinical knowledge and professional responsibility in attendance of cases of that nature.
