Os significados atribuídos ao cuidar de pacientes com aids

Este estudo apresenta o resultado de pesquisa envolvendo 27 profissionais da saúde, que atendem pacientes com aidsem enfermarias de isolamento, em Centro de Referência Regional para aids. Os dados do estudo, analisados e interpretados segundo a Fenomenologia Existencial, mostram a visão dos profissionais a respeito desse cuidado: trabalha-se com um paciente difícil, exigente, discriminado, embora deva ser visto como igual aos outros pacientes; o medo do contágio e o preconceito interferem na assistência e no relacionamento com este paciente; prejudicando a postura profissional; há a percepção a respeito dos efeitos deletérios do isolamento para os pacientes com aids, porém não se visualizam perspectivas para oferecer apoio efetivo. Os resultados sugerem a necessidade de implementar programas educativos e de apoio aos profissionais da área.

Knowledge of nursing undergraduate students about the use of contact precautions measures

To assess knowledge of nursing undergraduate students about the use of contact precautions. Methodology. There were 106 nursing undergraduate students from three universities within the state of Sao Paulo. The data collection was done between April and May 2012. A questionnaire was elaborated with questions assessing knowledge regarding contact precautions. The data were submitted to statistical procedures in the package MINITAB version 16. The knowledge were rated as adequate, partially adequate and inadequate. Results. There was a predominance of females (86%) and age group between 20 and 29 years (70%). Regarding the definition of contact precaution of diseases in which these measures are used, undergraduate’s knowledge was partially adequate (92% and 44%, respectively). The knowledge was considered adequate for the preventive measures used during assistance (86%). As difficulties mentioned in the use of these measures were discomfort, lack of material, personnel and time. Conclusion. Although undergraduate students know what measures to be used in contact precaution, they do not have adequate knowledge about which diseases they should use them. The three participating universities should reflect on the quality of training for nursing students regarding biosecurity and contact precautions.

Las sociologías del tiempo y las Tecnologías Avanzadas al servicio de la comunicación de los Pacientes UCI. Diseño, desarrollo y validación de un Sistema Interactivo de Comunicación para el entorno hospitalario

Introducción: El ingreso en UCI dificulta significativamente la interrelación familia-paciente. El aislamiento del paciente tiene repercusiones para todo su entorno e influye también en la relación con el personal sanitario. El aumento de la ansiedad dentro de la estructura UCI genera en este microsistema social una situación compleja en la que el equipo sanitario, el paciente y su familia deben manejarse. Se ha producido una reflexión significativa en relación con las políticas de gestión UCI-paciente-familia que ha permitido sugerir cambios de enfoque en la organización hospitalaria de los cuidados intensivos. Sin embargo, no se ha conseguido definir el modo en que la implementación de esos cambios puede articularse y se alerta recurrentemente sobre la ausencia de soluciones prácticas que ayuden a impulsar su introducción. Material y métodos: El proyecto MELIADE parte del análisis sociosistémico de este contexto mediante la aplicación de las metodologías de investigación de la Teoría Fundamentada y profundiza en el estudio de las variables que afectan a este complejo proceso relacional para comprender el porqué de la dificultad de introducir los cambios propuestos hasta el momento por los teóricos e identificar alternativas que los promuevan limitando el conflicto interno. Resultados: Como resultado, se sugieren nuevas alternativas basadas en las tecnologías avanzadas de la comunicación que permitan mejorar la percepción de la calidad asistencial para, superando las actuales dificultades, contribuir a rebajar la tensión de este entorno. El sistema MELIADE de comunicación familia-paciente cuenta ya con su primera versión software y sus características se presentan en este artículo.

Seclusion use with children and adolescents: an Australian experience

Objective: To summarize the current state of knowledge on the use of seclusion and restraint with children and adolescents and to report the findings of an exploratory study to identify factors that place a child or adolescent at increased risk of seclusion during their admission. Method: Literature searches were undertaken on MEDLINE, CINAHL and PsycINFO databases. Articles were identified that focused specifically on seclusion and restraint use with children and adolescents or contained material significant to this population. The study reports findings from a retrospective review of patient charts, seclusion registers and staffing from an Australian acute inpatient facility. Results: The data available in regard to seclusion use in this population is limited and flawed. Further research is needed on the use and outcomes of seclusion and restraint and on alternative measures in the containment of dangerousness. Both the literature and this study find that patients with certain factors are at increased risk of being secluded during an inpatient stay. These factors include being male, diagnoses of disruptive behaviour disorder and a previous history of physical abuse. Staffing factors did not show a relationship to the use of seclusion. Conclusions: There are patient factors that predict increased risk of seclusion; these factors and their interrelationships require further elucidation. Further research is also needed on the outcomes, both positive and negative, of seclusion use and of alternatives to seclusion.

Nursing care of the mechanically ventilated patient: What does the evidence say?: Part two

The care of the mechanically ventilated patient is a fundamental component of a nurse's clinical practice in the intensive care unit (ICU). Published work relating to the numerous nursing issues of the care of the mechanically ventilated patient in the ICU is growing significantly, yet is fragmentary by nature. The purpose of this paper is to provide a single comprehensive examination of the evidence related to the care of the mechanically ventilated patient. In part one of this two-part paper, the evidence on nursing care of the mechanically ventilated patient was explored with specific focus on patient safety: particularly patient and equipment assessment. This article, part two, examines the evidence related to the mechanically ventilated patient's comfort: patient position, hygiene, management of stressors (such as communication, sleep disturbance and isolation), pain management and sedation.

Isolation of nontuberculous mycobacteria (NTM) from household water and shower aerosols in patients with pulmonary disease caused by NTM

It has been postulated that susceptible individuals may acquire infection with nontuberculous mycobacteria (NTM) from water and aerosol exposure. This study examined household water and shower aerosols of patients with NTM pulmonary disease. The mycobacteria isolated from clinical samples from 20 patients included M. avium (5 patients), M. intracellulare (12 patients), M. abscessus (7 patients), M. gordonae (1 patient), M. lentiflavum (1 patient), M. fortuitum (1 patient), M. peregrinum (1 patient), M. chelonae (1 patient), M. triplex (1 patient), and M. kansasii (1 patient). One-liter water samples and swabs were collected from all taps, and swimming pools or rainwater tanks. Shower aerosols were sampled using Andersen six-stage cascade impactors. For a subgroup of patients, real-time PCR was performed and high-resolution melt profiles were compared to those of ATCC control strains. Pathogenic mycobacteria were isolated from 19 homes. Species identified in the home matched that found in the patient in seven (35%) cases: M. abscessus (3 cases), M. avium (1 case), M. gordonae (1 case), M. lentiflavum (1 case), and M. kansasii (1 case). In an additional patient with M. abscessus infection, this species was isolated from potable water supplying her home. NTM grown from aerosols included M. abscessus (3 homes), M. gordonae (2 homes), M. kansasii (1 home), M. fortuitum complex (4 homes), M. mucogenicum (1 home), and M. wolinskyi (1 home). NTM causing human disease can be isolated from household water and aerosols. The evidence appears strongest for M. avium, M. kansasii, M. lentiflavum, and M. abscessus. Despite a predominance of disease due to M. intracellulare, we found no evidence for acquisition of infection from household water for this species.

Stakeholder challenges in purchasing medical devices for patient safety.

OBJECTIVE: This study identifies the stakeholders who have a role in medical device purchasing within the wider system of health-care delivery and reports on their particular challenges to promote patient safety during purchasing decisions. METHODS: Data was collected through observational work, participatory workshops, and semi-structured qualitative interviews, which were analyzed and coded. The study takes a systems-based and engineering design approach to the study. Five hospitals took part in this study, and the participants included maintenance, training, clinical end-users, finance, and risk departments. RESULTS: The main stakeholders for purchasing were identified to be staff from clinical engineering (Maintenance), device users (Clinical), device trainers (Training), and clinical governance for analyzing incidents involving devices (Risk). These stakeholders display varied characteristics in terms of interpretation of their own roles, competencies for selecting devices, awareness and use of resources for purchasing devices, and attitudes toward the purchasing process. The role of "clinical engineering" is seen by these stakeholders to be critical in mediating between training, technical, and financial stakeholders but not always recognized in practice. CONCLUSIONS: The findings show that many device purchasing decisions are tackled in isolation, which is not optimal for decisions requiring knowledge that is currently distributed among different people within different departments. The challenges expressed relate to the wider system of care and equipment management, calling for a more systemic view of purchasing for medical devices.

Isolation of Alternaria alternata from an emollient cream:implications for public health

A specimen of emollient cream, which was observed to be contaminated peripherally with a filamentous fungus was examined for the presence of fungi and the resulting fungal colonies were examined phenotypically and genotypically. Subsequent DNA extraction and PCR amplification of the large internal transcribed spacer region [ITS1-5.8S-ITS2] yielded an amplicon of 512 bp. Sequence analysis identified this as Alternaria alternata at the 100% homology level with all 512/512 bases called. This organism has been previously reported as a cause of opportunistic infections involving skin and immunocompromised patients. This is the first report of an emollient cream as a source of this organism. It highlights the need for proper management of such preparations in order to minimize the potential spread of fungi to susceptible patient populations.

Rifampicin and sodium fusidate reduces the frequency of methicillin-resistant Staphylococcus aureus (MRSA) isolation in adults with cystic fibrosis and chronic MRSA infection

Nosocomial transmission of methicillin-resistant Staphylococcus aureus (MRSA) to patients with cystic fibrosis (CF) frequently results in chronic respiratory tract carriage. This is an increasing problem, adds to the burden of glycopeptide antibiotic use in hospitals, and represents a relative contraindication to lung transplantation. The aim of this study was to determine whether it is possible to eradicate MRSA with prolonged oral combination antibiotics, and whether this treatment is associated with improved clinical status. Adult CF patients (six male, one female) with chronic MRSA infection were treated for six months with rifampicin and sodium fusidate. Outcome data were examined for six months before treatment, on treatment and after treatment. The patients had a mean age of 29.3 (standard deviation=6.3) years and FEV(1) of 36.1% (standard deviation=12.7) predicted. The mean duration of MRSA isolation was 31 months. MRSA isolates identified in these patients was of the same lineage as the known endemic strain at the hospital when assessed by pulsed-field gel electrophoresis. Five of the seven had no evidence of MRSA during and for at least six months after rifampicin and sodium fusidate. The proportion of sputum samples positive for MRSA was lower during the six months of treatment (0.13) and after treatment (0.19) compared with before treatment (0.85) (P<0.0001). There was a reduction in the number of days of intravenous antibiotics per six months with 20.3+/-17.6 on treatment compared with 50.7 before treatment and 33.0 after treatment (P=0.02). There was no change in lung function. Gastrointestinal side effects occurred in three, but led to therapy cessation in only one patient. Despite the use of antibiotics with anti-staphylococcal activity for treatment of respiratory exacerbation, MRSA infection persists. MRSA can be eradicated from the sputum of patients with CF and chronic MRSA carriage by using rifampicin and sodium fusidate for six months. This finding was associated with a significant reduction in the duration of intravenous antibiotic treatment during therapy.

Aortic and Tricuspid Endocarditis in Hemodialysis Patient with Systemic and Pulmonary Embolism

This is a case report of a 43-year-old Caucasian male with end-stage renal disease being treated with hemodialysis and infective endocarditis in the aortic and tricuspid valves. The clinical presentation was dominated by neurologic impairment with cerebral embolism and hemorrhagic components. A thoracoabdominal computerized tomography scan revealed septic pulmonary embolus. The patient underwent empirical antibiotherapy with ceftriaxone, gentamicin and vancomycin, and the therapy was changed to flucloxacilin and gentamicin after the isolation of S. aureus in blood cultures. The multidisciplinary team determined that the patient should undergo valve replacement after the stabilization of the intracranial hemorrhage; however, on the 8th day of hospitalization, the patient entered cardiac arrest due to a massive septic pulmonary embolism and died. Despite the risk of aggravation of the hemorrhagic cerebral lesion, early surgical intervention should be considered in high-risk patients.

Isolation and isoenzyme characterization of Leishmania (Viannia) braziliensis from a case of human cutaneous leishmaniasis in northeast centre of the state of São Paulo

The diagnosis of human cutaneous leishmaniasis in small towns is sometimes made without the species identification of the Leishmania, even in areas without previous epidemiological surveys. Here we report the isolation of a Leishmania strain from a patient of Rincão, state of São Paulo, that was identified by isoenzyme characterization as L. (Viannia) braziliensis. Sand fly collections were made in the area where the patient live in order to investigate the likely vector species.

Isolation of Fonsecaea pedrosoi from thorns of Mimosa pudica, a probable natural source of chromoblastomycosis

Este trabalho demonstra o isolamento de Fonsecaea pedrosoi de espinhos da planta Mimosa pudica L., a partir do local de suposta infecção identificado pela paciente infectada. O diagnóstico clínico de cromoblastomicose foi estabelecido pelo achado de corpos fumagóides no exame microscópico direto e pelas culturas de F. pedrosoi do material obtido da lesão da paciente. A mesma espécie foi isolada da paciente e da planta. A microscopia eletrônica de transmissão da superfície dos espinhos evidenciou a disposição conidial característica de F. pedrosoi. Estes dados indicam que a planta M. pudica deve ser uma fonte natural de infecção do fungo F. pedrosoi.
