Isolation of Pseudomonas aeruginosa strains from dental office environments and units in Barretos, state of São Paulo, Brazil, and analysis of their susceptibility to antimicrobial drugs

A wide variety of opportunistic pathogens has been detected in the tubing supplying water to odontological equipment, in special in the biofilm lining of these tubes. Among these pathogens, Pseudomonas aeruginosa, one of the leading causes of nosocomial infections, is frequently found in water lines supplying dental units. In the present work, 160 samples of water, and 200 fomite samples from forty dental units were collected in the city of Barretos, State of São Paulo, Brazil and evaluated between January and July, 2005. Seventy-six P. aeruginosa strains, isolated from the dental environment (5 strains) and water system (71 strains), were tested for susceptibility to six antimicrobial drugs most frequently used against P. aeruginosa infections. Susceptibility to ciprofloxacin, followed by meropenem was the predominant profile. The need for effective means of reducing the microbial burden within dental unit water lines is emphasized, and the risk of exposure and cross-infection in dental practice, in special when caused by opportunistic pathogens like P. aeruginosa, are highlighted.

Programa de tratamento integral de pacientes crônicos do Hospital de Clinicas da Universidade do Estado do Rio de Janeiro: I - Etapa diagnóstica

O estudo sobre redundância de hospitalização, baseado no conceito de dependência aos cuidados de enfermagem, evidenciou que, em 99 pacientes que permaneceram 25 ou mais dias internados, foram redundantes em algum momento da internação, representando um desperdício de 1094 leitos-dia (30,17% do total de leitos-dia consumidos por este grupo de pacientes) . Estudou-se, também, um grupo de 102 pacientes com acompanhados durante uma semana, identificando-se 60 pacientes (59%) com hospitalização desnecessária. Não se verificou diferenças estatisticamente significativas entre os grupos de pacientes redundantes e não redundantes em relação às variáveis sócio-demográficas estudadas. As condições que contribuíram com maior número de dias de redundância foram neoplasias, doenças do aparelho respiratório (pneumopatia complicada e doença pulmonar obstrutiva crônica), fraturas, hipertensão arterial com ou sem insuficiência cardíaca, acidente vascular cerebral e cirrose hepática. Face a magnitude do desperdício de recursos decorrentes da hospitalização desnecessária e riscos para o paciente da permanência prolongada no hospital, é recomendada a implantação de programas experimentais para tratamento domiciliar de pacientes crônicos.

Legionnaires' disease in the renal transplant unit of "Hospital das Clinicas, FMUSP": during a five year period (1988-1993)

Several reports have related Legionella pneumophila with pneumonia in renal transplant patients, however this association has not been systematically documented in Brazil. Therefore this paper reports the incidence, by serologycal assays, of Legionella pneumophila serogroup 1 in these patients during a five year period. For this purpose sera from blood samples of 70 hospitalized patients with pneumonia from the Renal Transplant Unit of Hospital das Clinicas, FMUSP collected at the acute and convalescent phase of infection were submitted to indirect immunofluorescence assay (IFA) to demonstrate anti-Legionella pneumophila serogroup 1 antibodies. Of these 70 patients studied during the period of 1988 to 1993,18 (25.71 %) had significant rises in specific antibody titers for Legionella pneumophila serogroup 1. Incidence was interrupted following Hospital water decontamination procedures, with recurrence of infections after treatment interruption. In this study, the high susceptibility (25.71%) of immunodepressed renal transplant patients to Legionella pneumophila serogroup 1 nosocomial infections is documented. The importance of the implementation and maintenance of water decontamination measures for prophylaxis of the infection is also clearly evident.

O processo de definição e implementação de objetivos numa organização publica do setor saude : do conjunto sanatorial de Curicica ao Hospital de Clinicas Basicas Raphael de Paula Souza

Esta dissertação tem como objeto, o processo de definição e implementação de objetivos numa organização pública de saúde. Foi realizada uma revisão bibliográfica no campo das teorias organizacionais visando a identificar como as diferentes perspectivas teóricas(racional, natural, política e de integração) entendem o que sejam objetivos organizacionais e seu processo de definição e implementação. Foram identificadas também, algumas características destas organizações, as quais podem interferir no processo mencionado, provenientes de suas condições de serem públicas e de necessitarem de profissionais altamente qualificados para o seu funcionamento. Com base neste referencial teórico, foi realizado um estudo de caso numa organização pública de saúde - o Hospital Raphael de Paula Souza(Hospital de Curicica) - sobre o processo de transformação de seu perfil assistencial(de um hospital especializado em tisiologia para um hospital de clínicas básicas). Tem-se como pressuposto que uma compreensão mais adequada acerca da complexidade dos fatores intervenientes no processo de definição e implementação de objetivos das organizações públicas de saúde, poderá contribuir para que seus dirigentes(principais responsáveis pela sua condução) possam intervir ativamente naquele processo, minimizando as condições vigentes nestas organizações, de indefinição, incongruência e irresponsabilidade sobre seus objetivos. A reversão desta situação por sua vez, poderá contribuir também, para que nestas organizações, sejam alcançadas a eficiência e a eficácia, hoje tão insuficientes, porém absolutamente necessárias, não só a sua sobrevivência, mas para que respondam às necessidades de atendimento da população, razão principal de sua existência.

SISTEMAS QUIMILUMINESCENTES COM PEROXIDASE (EC:1.11.1.7) E SUAS APLICACOES EM ANALISES CLINICAS

The enzyme horseradish peroxidase HRP (EC:1.11.1.7), has both acid and basic isoenzymes, catalyses a wide range of reactions (acting as an oxiredutase or an oxidase) and is thought capable of one- or two-electrons oxidations depending on the substrate employed. Today, the methodology for these assay can be chemiluminescent reactions and enhanced chemiluminescent. The enhanced chemiluminescent assay with system HRP, luminol, peroxide and an enhancer has provided the basis for a convenient and sensitive assay for peroxidase and peroxidase conjugates, DNA probe and blotting assay. It is particularly more advantageous than the others, because is very rapid, more sensitive (attomoles), easy to do and technically simple, and is relatively specific for HRP (reduces the effect of the interference).

Avaliacao da atividade da nova cefalosporina de quarta geracao cefpiroma contra amostras clinicas isoladas em unidades de terapia intensiva e unidades de oncoematologia de varios hospitais brasileiros

Objective: To evaluate the in vitro activity of the fourth-generation cephalosporin cefpirome in comparison to that of ceftazidime, ceftriaxone, cefotaxime and imipenem in a multicenter study involving nine hospitals from six cities (four states). Material and methods: A total of 804 isolates from patients hospitalized in either intensive care units or Oncology/Hematology units was evaluated. The isolates were collected between June and November of 1995, i.e. before cefpirome became commercially available in Brazil, and susceptibility tested by broth microdilution following the NCCLS procedures. All isolates resistant to cefpirome were retested by B-test. Results: Against Enterobacteriaceae (n = 344), cefpirome demonstrated an activity 2 to 32-fold higher than that of the third-generation cephalosporins (TGCs) and similar to that of imipenem. The percentages of Enterobacteriaceae susceptible were: 88%, 69% and 96% for cefpirome, TGCs and imipenem, respectively, The cefpirome spectrum were greater or equal to that of imipenem against Citrobacter freundii, Enterobacter aerogenes, Morganellao morganii and Serratia marcescens. Against Acinetobacter sp. (n = 77), cefpirome was slightly more active than ceftazidime; however, the percentages of isolates resistant to these compounds were high (84% and 88%, respectively). The activities of cefpirome, ceftazidime and imipenem were very similar against P. aeruginosa isolates (n = 128), with MIC50 (μg/ml) percent susceptible of 8/59%, 8/62% and 4/62% respectively, Against aerobic gram-positive bacteria, the cefpirome activity was 4 to 16-fold higher than that of TGCs but 2 to 8-fold lower than that of imipenem. Conclusion: The results of our study suggest that, in Brazil, cefpirome has a spectrum of activity which is higher than that of the TGCs against aerobic gram-negative (Enterobacteriaceae and non-Enterobacteriaceae) and gram-positive bacteria and similar to that of imipenem against some Enterobacteriaceae species and P. aeruginosa.

Penfigo foliaceo no Hospital das Clinicas da Faculdade de Medicina de Botucatu, SP

BACKGROUND - Pemphigus foliaceus is an autoimmune bullous disease that is endemic in Brazil and in other South American countries such as Paraguay, Bolivia, Peru and Colombia. OBJECTIVES - To compare the observed clinical and epidemiological data with those referred in the literature. METHOD - Retrospective study in patients with pemphigus foliaceus admitted to and treated at University Hospital of the School of Medicine of Botucatu, SP, Brazil, from 1976 to 1993, analyzing the following variables: age, sex, race, origin and onset of disease. RESULTS - From 1976 to 1993, 63 patients were treated, with an average of 3.7 cases/year. Patients within the age range of 20 to 60 years old were the most affected. Most of the patients were white, females being slightly more affected than males. The majority of male patients were rural workers. Some towns presented higher incidence of cases. Most of the patients from rural areas became sick mainly in summer and in autumn. Occurrence of similar cases was observed in blood-related family members and neighbors. CONCLUSIONS - Clinical and epidemiological data were similar to those referred in the literature.

Cerâmicas odontológicas: propriedades, indicações e considerações clinicas

The demand for esthetic restorations has resulted in an increased use of dental ceramics and is the main alternative restorative material to tooth structure due to its favorable properties. Therefore, the aim of this work is to study the evolution of ceramic systems, involving different types and properties, indications, and clinical issues as aesthetic, cementing and longevity. In a detailed and advanced search in the database PubMed, 98 articles were found using the following key words: dental porcelain dental all-ceramic and ceramic according to the criteria for inclusion and exclusion left only 35 articles for review. Several ceramic systems are available in the market, making the prosthetic professionals need a constant recycling about their properties and directions, since good results are due to the selection of the best material for a particular case in all the skill of the practitioner.

Blood transfusion utilization and recipient survival at Hospital das Clinicas in Sao Paulo, Brazil

BACKGROUND: The characteristics of blood recipients including diagnoses associated with transfusion and posttransfusion survival are unreported in Brazil. The goals of this analysis were: 1) to describe blood utilization according to clinical diagnoses and patient characteristics and 2) to determine the factors associated with survival of blood recipients. STUDY DESIGN AND METHODS: A retrospective cross-sectional analysis was conducted on all inpatients in 2004. Data came from three sources: The first two files consist of data about patient characteristics, clinical diagnosis, and transfusion. Analyses comparing transfused and nontransfused patients were conducted. The third file was used to determine survival recipients up to 3 years after transfusion. Logistic regression was conducted among transfused patients to examine characteristics associated with survival. RESULTS: In 2004, a total of 30,779 patients were admitted, with 3835 (12.4%) transfused. These patients had 10,479 transfusions episodes, consisting of 39,561 transfused components: 16,748 (42%) red blood cells, 15,828 (40%) platelets (PLTs), and 6190 (16%) plasma. The median number of components transfused was three (range, 1-656) per patient admission. Mortality during hospitalization was different for patients whose admissions included transfusion or not (24% vs. 4%). After 1 year, 56% of transfusion recipients were alive. The multivariable model of factors associated with mortality after transfusion showed that the most significant factors in descending order were hospital ward, increasing age, increasing number of components transfused, and type of components received. CONCLUSION: Ward and transfusion are markers of underlying medical conditions and are associated with the probability of survival. PLT transfusions are common and likely reflect the types of patients treated. This comprehensive blood utilization study, the first of its kind in Brazil, can help in developing transfusion policy analyses in South America.
