Avaliação tardia da função renal em doentes com paracoccidioidomicose tratados com anfotericina B por meio da determinação do ritmo de filtração glomerular com EDTA Cr51

A late survey of the renal function was performed in eighteen patients with paracoccidioidomycosis treated with amphotericin B, according to the glomerular filtration rate (RFG). The method was compartment analysis by single injection using EDTA Cr51, determined by its 'half biological life' and dosages of blood urea nitrogen and creatinine. The patients were seventeen males and one female. They were from 22 to 76 years old. Ten of these patients received 2 g of amphotericin B and eight of them received 4 g. There were no expressive difference between the two groups, taking into account age, dose in mg/kg of weight/day, time of conclusion of the treatment, urea, creatinine, glomerular filtration was smaller than the normal, and average of the half biological life of the EDTA Cr51 was large than the normal. The achieved results permitted us to consider that the amphotericin B determines deficit of renal function. However, by the present study, it hasn't been possible to affirm if the modifications are definitive.

Estudo sobre a resistencia aos antimicrobianos em bacterias isoladas de pacientes hospitalizados (Botucatu, 1988-1992)

Since 1988 to 1992, a study about susceptibility to antimicrobial drugs of bacterias isolated from hospitalized patients was performed. The compared susceptibility to important drugs (ampicillin, cephalotin, cefoxitin, ceftaxizime, ceftriaxone, aztreonam, gentamicin, amikacin, pefloxacin, ciprofloxacin, imipenem, oxacillin and vancomycin) was investigated in 1200 strains (300 of each specie) of the prevalent bacterias: E. coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and S. aureus. Minimal inhibitory concentration (MIC) was determined by agar dilution method, using from 0.05 to 256 mcg of each drug per ml of culture medium (Mueller-Hinton). Ranges of MIC, MIC(50%), MIC(90%) and the proportion of resistant strains were determined and permitted to know the 4 drugs that were found to be more active against bacterias; the CIM(90%) values are: E. coli - aztreonam (0.1 mcg/ml), pefloxacin (0.1), ceftazidime (0.25) and ceftriaxone (0.05); K. pneumoniae-aztreonam (0.25) ceftriaxone (0.25), ceftazidime (0.5) and pefloxacin (2.0); P. aeruginosa-imipenem (4.0), aztreonam (16), ceftazidime (16) and ciprofloxacin (16); S. aureus-vancomycin (1.01, ciprofloxacin (8, 0), amikacin (128) and cephalothin (128 mg/ml). The better 'in vitro' antibacterial activity observed was related to: aztreonam (77-100% of the sensitive strains), ceftazidime (50-99,7%), pefloxacin (73-99,7%), ciprofloxacin (80%), imipenem (93%) and vancomycin (100%).

The better in vitro antibacterial activity observed was related to: aztreonam (77-100% of the sensitive strains), ceftazidime (50-99,7%), pefloxacin (73-99,7%), ciprofloxacin(80%), imipenem (93%) and vancomicin (100%).

Avaliação dos produtos de degradação oxidativa da Hb S em eritrócitos de doentes falcêmicos

Analysis of the products of oxidative degradation of Hb S was made by methahemoglobin measurement and a count of red blood cells with Heinz bodies. Free radicals originating from oxidation cause extensive injury to erythrocytes, decreasing their useful survival period especially in Hb S carriers. The Superoxide ion (O 2) is the most responsible for the oxidation process of Hb forming membrane-bound haemachromes which afterwards evolve to Heinz bodies, damaging the membrane and provoking erythrocytes hemolysis. The results from this work showed that the SS genotype is more susceptible to the action of the free radicals than the S/Tal genotype. The β genotype has a lower oxidative susceptibility than the SS because it has only one β s mutation. The results allowed us to conclude that: a) the simple presence of Hb S, independent of its genotype and its concentration, is sufficient to produce methaemoglobin from this Hb; b) there is not a direct relationship between methaetnoglobin concentration and the Heinz bodies count; c) the intensity of Heinz bodies in the sickled erythrocytes seems to be independent of the Hb Fetal concentration; d) The genotype SS is more susceptible to Hb oxidation with the release of products of oxidative degradation; e) methaemoglobin formation in blood of people with Hb AA and Hb AS, assessed over 24, 48, 72 and 163 hourly-periods, showed greater oxidative intensity in the Hb AS compared with Hb AA.

Grau de dependência de idosos hospitalizados para realização das atividades básicas da vida diária1

This study aimed to identify the level of dependence in elderly inpatients when performing Basic Activities of Daily Living. This quantitative, cross-sectional, descriptive study was conducted in the Adult Ward of the Botucatu University Hospital Emergency Unit - UNESP, Brazil. Data was collected by means of interviews, observation, and individual medical chart consultation, to be analyzed via logistic regression using the statistical software package SAS for Windows, version 9.2. The sample consisted of 71 subjects with a mean age of 74.30 years. It was observed that 30.99% of the older individuals showed to be independent in performing the proposed activities; 22.53% were partly dependent; and 46.48% were fully dependent. Gerontology care must aim at maintaining functional conditions, thus promoting independence and preserving these individuals' dignity.

(Em defesa dos) Cuidados Paliativos na Atenção Primária à Saúde

One of the basic principles of the Brazilian Public Health System (SUS) is integral assistance, which considers the integrality of the individual, of service and care, which should necessarily include end of life care. Our aim was to analyze the work process of health professionals at the Family Health Strategy / Primary Care that already cared for people in the dying process to propose viable contributions to the Public Health area as regards the implementation of Palliative Care in Primary Care. We present data referring to the following themes: Singular Therapeutic Project (PTS); death quality as PTS goal (work purpose); the team's ways of doing (bonding as a pact condition). Eleven health professionals (four nurses and seven physicians) linked to the Family Health Strategy (ESF) of Campinas (São Paulo) participated on this research. From the interviews, data analysis followed the Socio-Historical Psychology theoretical and methodological approach. The professionals' activity was analyzed in articulation with the specificities of caring for people in the dying process. We found that action planning in health is oriented by the Singular Therapeutic Project (PTS), with an emphasis in social diagnosis and the need of a bond for attaining a pact. It is understood that the purpose of health professionals' activity is to promote dignity and life quality in the dying process, but integral care should include not only individual and family care, but also the defence of full human development during all phases of life.
