Factores de risco para doenças músculo-esqueléticas não específicas no sector das limpezas em ser

The aim of this paper is to characterize complaints in the upper limbs, shoulders, neck and back- lumbar region directly related to musculo-skeletal disorders in a sampling of 114 cleaners from seven cleaning (janitor) companies, operating at eight client organizations. Complaints had been diagnosed as stiffness, any pain, numbness, paraesthesiae, tingling, cold feeling and blanching of at least one finger tip, according to a temporal criteria of symptoms were present now or have been present on at least 4 days during the last 7 days, or symptoms have been present on at least 4 days during at least one week in the last 12 months. It was analyzed the severity of the complaints (interference with current activities) and the simultaneous occurrence of multiple symptoms. The causes of medical consultation in the last year were analyzed (osteo-articular pathology of the vertebral spine, of the upper and lower limbs, depressive syndromes and other complaints of the lower limbs among others). In the end, the relation between persistent complaints and musculo- skeletal pathology related to work activities was analyzed, considering particularly the age of the workers and the existence of osteo-articular pathology.

Primary liver AIDS-related lympoma

Non-Hodgkin's lymphomas (NHL) are the second most frequent malignancies in AIDS patients. The majority of NHL associated with AIDS involves extranodal sites, especially the digestive tract and the central nervous system. Primary liver lymphoma (PLL) is an uncommon neoplasm among these patients. Ultrasonography and computed tomography scans may be helpful in the diagnosis of focal hepatic lymphoma. Image-guided fine-needle biopsy with histopathology of the liver lesions is the gold standard for the diagnosis of hepatic lymphoma. We report a case of PLL as the initial manifestation of AIDS in a patient without any previous infection by hepatitis C or B virus, presented as multiple and large hepatic masses.

Successful control program to implement the appropriate antibiotic prophylaxis for cesarean section

OBJECTIVE: Describe implementation of a successful program to reduce doses (cefazolin 2 to 1 g) used for antimicrobial prophylaxis. METHODS: Evaluation of an intervention program to reduce prophylactic antimicrobial doses. The intervention included weekly staff discussions, automatic dispensation of 1g-vial of cefazolin by the pharmacy unless expressly requested by surgeon and increase in post-discharge surveillance as a strategy to reassure surgeons of the safety of the reduction. In the pre and post intervention periods, a prospective study of antimicrobial consumption and surgical site infections were measured. RESULTS: There were 5,164 and 5,204 deliveries in 2001-2002 and 2003-2004, respectively; 1,524 (29.5%) and 1,363 (26%) were cesarean sections. There was a 45% decrease in cefazolin vials used on average per cesarean section (2.29 to 1.25). Patients evaluated increased from 16% to 67% and the SSI rates in both periods were 3.34% to 2.42%, respectively. CONCLUSION: An ample intervention, including administrative and educational measures, led to high compliance with dose reduction and saved more than US$4,000 in cefazolin, considered important because government reimbursement in Brazil for cesarean section is $80.

Pseudo-outbreak of Clostridium difficile associated diarrhea (CDAD) in a tertiary-care hospital

The objective of this study was to describe a pseudo-outbreak of C. difficile in a hospital, following a change in the method used to detect the toxin. In February 2002, there were two cases of CDAD and in March 7 occurred, coinciding with a change of the test (from detection of toxin A to toxin A/B). An outbreak was suspected. Active surveillance and education of staff were started. A CDAD case was defined as a patient with acute onset of diarrhea (³ three episodes of liquid stools) and a positive stool test. They were classified as hospital or community-acquired. Stool samples were also collected for C. difficile culture and isolates were typed using AP-PCR. From March 2002 through December 2003 there were 138 cases of CDAD: 70% were hospital-acquired and among the 30% with CDAD present on admission, most (81%) came directly from the community (50% had no history of hospitalization). Fifty-two percent of hospital-acquired CDAD and 94% of cases on admission had already used antibiotics. The incidence of CDAD in hospitalized patients during surveillance was 3.3 per 1000 patient-admissions. The incidence of CDAD present on admission was 6.1/1000 patients. Sixteen isolates were typed and presented 13 different profiles. In conclusion, the CDAD increase in our study occurred due to change in diagnostic methods and not due to an outbreak, as suspected initially. The incidence in hospitalized patients was much lower than in reported outbreaks. There were 13 molecular types suggesting that an outbreak did not occur. CDAD was largely community-acquired.

A filter inexact-restoration method for nonlinear programming

A new iterative algorithm based on the inexact-restoration (IR) approach combined with the filter strategy to solve nonlinear constrained optimization problems is presented. The high level algorithm is suggested by Gonzaga et al. (SIAM J. Optim. 14:646–669, 2003) but not yet implement—the internal algorithms are not proposed. The filter, a new concept introduced by Fletcher and Leyffer (Math. Program. Ser. A 91:239–269, 2002), replaces the merit function avoiding the penalty parameter estimation and the difficulties related to the nondifferentiability. In the IR approach two independent phases are performed in each iteration, the feasibility and the optimality phases. The line search filter is combined with the first one phase to generate a “more feasible” point, and then it is used in the optimality phase to reach an “optimal” point. Numerical experiences with a collection of AMPL problems and a performance comparison with IPOPT are provided.

As guerras peninsulares na música portuguesa

No campo da música erudita, os efeitos mais profundos das invasões francesas, de 1807 a 1810, não se sentiram de imediato. A fuga da família real portuguesa para o Brasil e a tomada de Lisboa pelas tropas de Junot, em Novembro de 1807, longe de produzir um colapso na vida artística da capital, resultaram meramente numa mudança de direcção, pois a missão francesa não era apenas militar e econômica mas, em todos os sentidos, política. No caso específico do Teafro de São Carlos, por exemplo, o libreto da ópera Ifigênia in Aulide, do compositor italiano Luigi Giannella (?1778- -1817), representada em estreia absoluta a 16 de Janeiro de 1808, deixa a nova política bem clara.i Num Avertissement, o libretista, Stefano Vestris, afirma como se esforçara para escrever um texto adequado à nova situação em que o teatro «livre à Ia saine critique de Ia raison, et du goút, pourrait sortir de 1'état d'abjection dans le quel il se trouve maintenant.»^ O mais prestigiado compositor português da época, Marcos Portugal (1762-1830), foi, aparentemente, obrigado pelas autoridades francesas a assumir o cargo de maestro do Teatro, onde reviu substancialmente a sua ópera Demofoonte para celebrar o aniversário natalício de Napoleão, a 15 de Agosto.3 Contudo, no dia 30 do mesmo mês, na seqüência da derrota das tropas francesas na Batalha do Vimeiro, foi assinado o Tratado de Sintra, e em meados de Setembro Lisboa viu-se libertada pelas tropas inglesas e portuguesas, criando, assim, uma nova situação bastante diferente.

Smqnr VARIANTS IN CLINICAL ISOLATES OF Stenotrophomonas maltophilia IN BRAZIL

SUMMARYStenotrophomonas maltophilia contains a novel chromosomally-encoded qnr gene named Smqnr that contributes to low intrinsic resistance to quinolone. We described Smqnr in 13 clinical isolates of S. maltophilia from two Brazilian hospitals, over a 2-year period. The strains were identified by API 20 NE (bioMérieux, France). Susceptibility by microdilution method to trimetroprim/sulfamethoxazole, ciprofloxacin, levofloxacin, minocycline, ceftazidime, chloramphenicol and ticarcillin/clavulanate was performed according to CLSI. PCR detection of Smqnr gene was carried out. The sequence of Smqnr was compared with those deposited in GenBank. Pulsed-field gel electrophoresis (PFGE) of all strains was performed. Thirteen Smqnr positives isolates were sequenced and three novel variants of Smqnr were identified. All 13 Smqnr isolates had distinguishable patterns by PFGE. This is the first report of Smqnr in S. maltophilia isolated in Brazil.

POLYCLONAL OUTBREAK OF BLOODSTREAM INFECTIONS CAUSED BY Burkholderia cepacia COMPLEX IN HEMATOLOGY AND BONE MARROW TRANSPLANT OUTPATIENT UNITS

Aim: The objective was to describe an outbreak of bloodstream infections by Burkholderia cepacia complex (Bcc) in bone marrow transplant and hematology outpatients.Methods: On February 15, 2008 a Bcc outbreak was suspected. 24 cases were identified. Demographic and clinical data were evaluated. Environment and healthcare workers' (HCW) hands were cultured. Species were determined and typed. Reinforcement of hand hygiene, central venous catheter (CVC) care, infusion therapy, and maintenance of laminar flow cabinet were undertaken. 16 different HCWs had cared for the CVCs. Multi-dose heparin and saline were prepared on counter common to both units.Findings: 14 patients had B. multivorans(one patient had also B. cenopacia), six non-multivorans Bcc and one did not belong to Bcc. Clone A B. multivorans occurred in 12 patients (from Hematology); in 10 their CVC had been used on February 11/12. Environmental and HCW cultures were negative. All patients were treated with meropenem, and ceftazidime lock-therapy. Eight patients (30%) were hospitalized. No deaths occurred. After control measures (multidose vial for single patient; CVC lock with ceftazidime; cleaning of laminar flow cabinet; hand hygiene improvement; use of cabinet to store prepared medication), no new cases occurred.Conclusions: This polyclonal outbreak may be explained by a common source containing multiple species of Bcc, maybe the laminar flow cabinet common to both units. There may have been contamination by B. multivorans (clone A) of multi-dose vials.

INCIDENCE OF DIARRHEA BY Clostridium difficile IN HEMATOLOGIC PATIENTS AND HEMATOPOIETIC STEM CELL TRANSPLANTATION PATIENTS: RISK FACTORS FOR SEVERE FORMS AND DEATH

We describe the rate of incidence of Clostridium difficile-associated diarrhea (CDAD) in hematologic and patients undergone stem cell transplant (HSCT) at HC-FMUSP, from January 2007 to June 2011, using two denominators 1,000 patient and 1,000 days of neutropenia and the risk factors associated with the severe form of the disease and death. The ELISA method (Ridascreen-Biopharm, Germany) for the detections of toxins A/B was used to identify C. difficile. A multivariate analysis was performed to evaluate potential factors associated with severe CDAD and death within 14 days after the diagnosis of CDAD, using multiple logistic regression. Sixty-six episodes were identified in 64 patients among 439 patients with diarrhea during the study period. CDA rate of incidence varied from 0.78 to 5.45 per 1,000 days of neutropenia and from 0.65 to 5.45 per 1,000 patient-days. The most common underlying disease was acute myeloid leukemia 30/64 (44%), 32/64 (46%) patients were neutropenic, 31/64 (45%) undergone allogeneic HSCT, 61/64 (88%) had previously used antibiotics and 9/64 (13%) have severe CDAD. Most of the patients (89%) received treatment with oral metronidazole and 19/64 (26%) died. The independent risk factors associated with death were the severe form of CDAD, and use of linezolid.

Transmissão do Citomegalovírus no Leite Materno nos Recém-Nascidos Pré-Termos ou Muito Baixo Peso

A infecção pós-natal a citomegalovírus (CMV) nos recém-nascidos pré termos (RNPT) ou muito baixo peso (MBP) pode cursar com doença grave. Para avaliar a transmissão do CMV no leite materno, no RNPT ou MBP, a infecção e o prognóstico a longo prazo, efectuamos uma pesquisa online no motor de busca OVID (consultando a Pubmed, Medline e a Medscape) de Janeiro de 1982 a Agosto de 2011. Os estudos que incluíam a infecção congénita foram excluídos. Incluímos cerca de 30 estudos para análise. A taxa de infecção materna assintomática é elevada (média 81%) e a transmissão do CMV no LM varia entre 66-97,2% das mães CMV-IgC positivas com subsequente positividade nos RN entre 5.7 – 58.6%. Sendo as taxas de infecção sintomática (0-34,5%) e/ou de doença grave (0-13,8%) muito variáveis de estudo para estudo. A longo prazo pode cursar com perturbações do neurodesenvolvimento e morbilidade importantes, sem compromisso auditivo. Em relação à inactivação do CMV pode-se optar por pasteurizar ou congelar o LM, com eficácia/benefício/custo variável. As recomendações actuais são variáveis e pouco directivas, deixando nalguns casos ao critério individual.

The Role of Propranolol in the Treatment of Infantile Hemangioma

INTRODUCTION: Infantile hemangioma (IH) is one of the most common childhood tumors. There are various medical or surgical therapeutic options, all with suboptimal results. Recently, the successful use of propranolol for involution of IH was described. We report the results of a single-center experience with this therapeutic option. OBJECTIVE: To prospectively assess the efficacy and safety of propranolol in children with infantile hemangioma. METHODS: We performed a prospective analysis of clinical data of all patients with IH referred to a pediatric cardiology center for baseline cardiovascular assessment prior to propranolol therapy. Propranolol was given at a starting dose of 1 mg/kg/day and titrated to a target dose of 2-3 mg/kg/day according to clinical response. Efficacy was assessed through a photograph-based severity scoring scale. Safety was assessed by collecting data regarding significant side effects. RESULTS: Starting in 2010, 30 patients (15 female) were referred for propranolol treatment of IH, at a median age of six months (1-63 months). The mean target propranolol dose was 2.8 mg/kg/day, with a mean duration of therapy of 12 months. All patients experienced significant reduction of IH size and volume. There were no side effects. CONCLUSIONS: In our experience propranolol appears to be a useful and safe treatment option for severe or complicated IH, achieving a rapid and significant reduction in their size. No adverse effects were observed, although until larger clinical trials are completed, potential adverse events should be borne in mind and consultation with local specialists is recommended prior to initiating treatment.

Série das invasões francesas”: análise da imagética. Uma visão Ibérica sobre um inimigo exterior

Dissertação de Mestrado em História de Arte - Variante Contemporânea

História Interdisciplinar e a Análise de Crônicas Portuguesas do Século XV

Nesse artigo, exploramos a idéia de interdisciplinaridade que permeia a disciplina História há longos anos. É através da proposta de uma análise interdisciplinar de crônicas medievais portuguesas que procuramos entender um pouco melhor o fazer histórico sobre a medievalidade nos dias atuais. Assim, ao discorrermos sobre a História Cultural em sintonia com a Análise do Discurso, esperamos chamar atenção para a multiplicidade de interpretações e leituras das fontes medievais. Para esse trabalho, destacamos e analisamos alguns trechos de duas crônicas do fim do Medievo português. Essas obras são: Crônica da Tomada de Ceuta (1449-50) e Crônica de Guiné (1452-53), ambas da pena de Gomes Eanes de Zurara (1410-74). Nos excertos escolhidos, buscamos demonstrar como se deu a construção de um ideal de nobreza e cavalaria na obra desse cronista luso.

Duques e cenas tristes: ainda a Convenção de Sintra (1808)

Na passagem do 2º centenário da assinatura da Convenção de Sintra (30 de Agosto de 1808), que pôs oficialmente termo à primeira invasão e ocupação francesas de Portugal, protagonizadas pelo General Jean-Andoche Junot (1771-1813) entre Novembro de 1807 e Setembro de 1808, não poderia esta Revista alhear-se de um episódio e um documento tão marcantes da Guerra Peninsular, tanto mais quanto a existência (ou subsistência...) de pontos controversos abre espaço para possíveis projectos internacionais de investigação comparatista e pluridisciplinar. Assim sendo, este ensaio pretende, de forma tentativa, retomar alguns testemunhos idealmente conducentes a eventuais releituras anglo-portuguesas da referida Convenção.
