Estudo de vinte casos de hiperadrenocorticismo no cão

O hiperadrenocorticismo canino consiste no conjunto de alterações físicas e bioquímicas resultantes da exposição prolongada e inapropriada, do organismo, a elevadas concentrações de cortisol. Esta dissertação teve como principal objectivo o estudo de vinte casos de hiperadrenocorticismo no cão, com base na recolha e interpretação de dados clínicos, laboratoriais e de imagem, efectuados durante o período de dois anos, entre Março de 2010 e Março de 2012, no Hospital Veterinário da FMVZ/UNESP em Botucatu. Constatou-se que a maioria das características individuais (idade, peso, raça e sexo), sinais clínicos e alterações laboratoriais (hemograma, bioquímicas sanguíneas e urianálise) comuns desta doença estavam presentes. Os cães do nosso estudo eram na sua maioria geriátricos, de raça miniatura como o caniche, com peso inferior a 20 Kg e do sexo feminino; estes apresentavam habituais sinais clínicos como poliúria, polidipsia, distensão abdominal, polifagia, fraqueza muscular, alterações respiratórias, cutâneas e neurológicas, e habituais alterações laboratoriais como trombocitose, linfopenia, eosinopenia, neutrofilia, aumento da fosfatase alcalina sérica, alanina aminotransferase, colesterol e triglicéridos. Alguns destes cães apresentaram ainda três das complicações mais comuns do hiperadrenocorticismo como hipertensão arterial, infecção do tracto urinário inferior e diabetes mellitus. Para chegar ao diagnóstico final realizou-se o teste de supressão de dexametasona a baixas doses em associação com a avaliação das glândulas adrenais através de ecografia, o qual nos permitiu obter a nossa amostra final, os vinte cães com hiperadrenocorticismo. Este estudo contribuiu para aprofundar o conhecimento relativamente às alterações clínicas, laboratoriais e de imagem presentes nos cães com hiperadrenocorticismo e demonstrou que a informação daí retirada é fundamental para chegar ao seu diagnóstico.

Caracterização das infeções do trato urinário de origem microbiana : casuística de um Hospital Veterinário de Lisboa

As infeções do trato urinário (ITU’s) são doenças infeciosas frequentes na prática clínica veterinária, sendo fundamental uma correta antibioterapia, principalmente pelo crescente desenvolvimento de resistências bacterianas aos antibióticos. Realizou-se um estudo retrospetivo, englobando 86 animais admitidos no Hospital Veterinário do Restelo, submetidos a urocultura, com o objetivo de caracterizar as ITU’s microbianas neste hospital, avaliando a sua epidemiologia e suscetibilidade antibiótica das bactérias isoladas. Da totalidade das uroculturas realizadas (n=86), 28 foram positivas, 18 em canídeos e 10 em felídeos, sem predisposição racial, mais em fêmeas nos canídeos e em machos nos felídeos. A idade média dos animais com ITU foi 8 anos nos canídeos e 10 anos nos felídeos. Todas as ITU´s foram monobacterianas, sendo o microorganismo mais frequentemente isolado a Escherichia coli. Verificou-se multirresistência em 10 das 28 bactérias isoladas. A gentamicina foi o antibiótico com melhor perfil de sensibilidade global e o que apresentou mais resistências foi a tetraciclina. O antibiótico mais prescrito de forma empírica foi a enrofloxacina. Este estudo,especialmente se realizado de forma periódica, poderá ser um contributo para a elaboração de guias institucionais de antibioterapia adequada e minimização do aparecimento de resistências bacterianas.

Nocturia is not associated with falls among the elderly: a population study in the city of Sao Paulo

Introduction: the present study aims to evaluate the association between nocturia and falls in a group of community-living elderly men in the city of Sao Paulo (Brazil). Material and methods: under the coordination of the Pan American Health Organization and World Health Organization, a multicenter study named Health, Welfare and Aging (SABE Study) is being conducted to evaluate the living and health conditions of older people in Latin America and Caribbean. In Brazil, this study is evaluating the elderly population (60 years or more) in Sao Paulo since 2000. The presence of nocturia was taken as the response ""yes"" to the question ""Do you need to void three times or more at night?"". The presence of falls was also taken as the response ""yes"" to the question ""Did you have any fall during the last 12 months?"" The intergroup analysis used was the logistic regression. Results: total of 865 men was interviewed, mean age 68 years. It was observed high prevalence of nocturia and falls in all groups, with higher prevalence of both in the eldest group (p < 0.001), however, the association of nocturia and falls was not statistically significant in any of the groups (p = 0.45). Conclusion: this is one of the pioneering studies that assess only the male population, showing that nocturia was not significantly associated with falls. Nocturia and falls are highly prevalent conditions in the elderly, but no association was found between both, so that these variables may be correlated to age and other clinical conditions.

N-acetylcysteine protects against renal injury following bilateral ureteral obstruction

Background. Obstructive nephropathy decreases renal blood flow (RBF) and glomerular filtration rate (GFR), causing tubular abnormalities, such as urinary concentrating defect, as well as increasing oxidative stress. This study aimed to evaluate the effects of N-acetylcysteine (NAC) on renal function, as well as on the protein expression of aquaporin 2 (AQP2) and endothelial nitric oxide synthase (eNOS), after the relief of bilateral ureteral obstruction (BUO). Methods. Adult male Wistar rats were divided into four groups: sham (sham operated); sham operated + 440 mg/kg body weight (BW) of NAC daily in drinking water, started 2 days before and maintained until 48 h after the surgery; BUO (24-h BUO only); BUO + NAC-pre (24-h BUO plus 440 mg/kg BW of NAC daily in drinking water started 2 days before BUO); and BUO + NAC-post (24-h BUO plus 440 mg/kg BW of NAC daily in drinking water started on the day of BUO relief). Experiments were conducted 48 h after BUO relief. Results. Serum levels of thiobarbituric reactive substances, which are markers of lipid peroxidation, were significantly lower in NAC-treated rats than in the BUO group rats. The administration of NAC provided significant protection against post-BUO GFR drops and reductions in RBF. Renal cortices and BUO rats presented decreased eNOS protein expression of eNOS in the renal cortex of BUO group rats, whereas it was partially recovered in BUO + NAC-pre group rats. Urine osmolality was significantly lower in BUO rats than in sham group rats or NAC-treated rats, the last also presenting less interstitial fibrosis. Post-BUO downregulation of AQP2 protein expression was averted in the BUO + NAC-pre group rats. Conclusions. This study demonstrates that NAC administration ameliorates the renal function impairment observed 48 h after the relief of 24-h BUO. Oxidative stress is important for the suppression of GFR, RBF, tissue AQP2 and eNOS in the polyuric phase after the release of BUO.

Long-term nitric oxide deficiency causes muscarinic supersensitivity and reduces beta(3)-adrenoceptor-mediated relaxation, causing rat detrusor overactivity

Background and purpose: Overactive bladder is a complex and widely prevalent condition, but little is known about its physiopathology. We have carried out morphological, biochemical and functional assays to investigate the effects of long-term nitric oxide (NO) deficiency on muscarinic receptor and beta-adrenoceptor modulation leading to overactivity of rat detrusor muscle. Experimental approach: Male Wistar rats received No-nitro-L-arginine methyl ester (L-NAME) in drinking water for 7-30 days. Functional responses to muscarinic and b-adrenoceptor agonists were measured in detrusor smooth muscle (DSM) strips in Krebs-Henseleit solution. Measurements of [H-3] inositol phosphate, NO synthase (NOS) activity, [H-3] quinuclidinyl benzilate ([H-3]QNB) binding and bladder morphology were also performed. Key results: Long-term L-NAME treatment significantly increased carbachol-induced DSM contractile responses after 15 and 30 days; relaxing responses to the beta(3)-adrenoceptor agonist BRL 37-344 were significantly reduced at 30 days. Constitutive NOS activity in bladder was reduced by 86% after 7 days and maintained up to 30 days of L-NAME treatment. Carbachol increased sixfold the [H-3] inositol phosphate in bladder tissue from rats treated with L-NAME. [H-3] QNB was bound with an apparent KD twofold higher in bladder membranes after L-NAME treatment compared with that in control. No morphological alterations in DSM were found. Conclusions and implications: Long-term NO deficiency increased rat DSM contractile responses to a muscarinic agonist, accompanied by significantly enhanced KD values for muscarinic receptors and [H-3] inositol phosphate accumulation in bladder. This supersensitivity for muscarinic agonists along with reductions of beta(3)-adrenoceptor-mediated relaxations indicated that overactive DSM resulted from chronic NO deficiency.

Infecção hospitalar no Centro de Tratamento Intensivo Geral de um hospital escola da Região Sul do Brasil

Objetivos Avaliamos a incidência de infecção hospitalar no CTI clínico-cirúrgico de um hospital escola no sul do Brasil. Foram utilizadas taxas ajustadas para o tempo de permanência dos pacientes e para o tempo de exposição aos procedimentos invasivos. Também investigamos a influência da causa básica de internação (trauma, neurológico e clínico-cirúrgico) nas taxas de infecções. Material e Métodos Os pacientes internados no CTI Clínico-cirúrgico de março a dezembro de 1999, foram prospectivamente seguidos para a detecção de infecção hospitalar. Para o diagnóstico de infecção hospitalar utilizou-se as definições do Centro de Controle e Prevenção de Doenças dos EUA (CDC) e as taxas foram calculadas de acordo com a metodologia NNIS (Sistema Nacional de Vigilância Epidemiológica). Resultados Foram acompanhados 686 pacientes (4201 pacientes-dia). Ocorreram 125 infecções hospitalares, sendo que a incidência global foi de 18,2% ou 29,8 infecções por 1000 pacientes-dia. Os sítios de infecção mais freqüente foram: pneumonia (40%), infecção urinária (24%) e septicemia primária (12,8%). As taxas de infecções hospitalares, associadas aos procedimentos invasivos, foram as seguintes: 32,2 pneumonias por 1000 ventiladores mecânico-dia, 9,7 infecções urinárias por 1000 sondas vesicais-dia e 7 septicemias por 1000 cateteres venosos centrais-dia. A incidência global de infecção nos pacientes com trauma (26,8) e neurológicos (20,7%) foi superior quando comparada com o grupo clínico-cirúrgico (12,2%), p < 0,001. Conclusões Encontramos altas taxas de infecções relacionadas com os procedimentos invasivos neste CTI. A causa básica de internação influenciou as taxas de infecção, sugerindo a necessidade de analisar-se estratificadamente os pacientes em CTI clínico-cirúrgico.

Infecção do trato urinário associada à sondagem vesical numa unidade de terapia intensiva

A descriptive, quantitative approach and non-participant observation study, which was aimed at analyzing the association between knowledge and practice of inclusion and maintenance of urinary catheter by nursing professionals in the occurrence of urinary tract infection, performed in the ICU of Onofre Lopes University Hospital in Natal / RN. The original sample was composed of 42 nursing staff professional, five (5) nurses and 37 nursing technicians, 27 of them were outsourced (FUNPEC and IEL fellows) and 10 servers UFRN. Data collection was performed using two instruments, the first observation procedures used in the insertion and manipulation of indwelling urinary catheter (IUC) and the second with a questionnaire that addressed the characterization data of respondents, knowledge and conduct the insertion and manipulation of the IUC. The results were tabulated in Microsoft Excel and analyzed using SPSS software, version 15.0. We found the prevalence of institutional staff members on outsourcing - IEL and FUNPEC - (64.3%) were female (69.0%), aged 21 to 35 years (59.5%) and with mid-level education (88.1%). As to knowledge, we found that the nurses had levels of good to excellent and the nursing technicians, to regulate the poor. The nurses made a mistake when choosing IUC (40.0%) and washing hands (30.0%) and technicians on hand washing (74.4%) and the contents of the tray (34.7%). In relation to the conduct of insertion of IUC, the nurses made a mistake when choosing SVD (66.7%) and washing hands (57.1%). Regarding the handling of IUC/drainage system, the technicians were wrong more about washing their hands (56.0%). Analyzing the misconduct to the categorization of knowledge, we saw that the nursing staff who had missed more had inadequate knowledge (ρ = 0.001). At the end we found the risk of a patient to acquire UTI is higher in two and a half times when there is a large number of mismatches, patient spends more time using the IUC and hospitalized in the ICU. As regards the study hypotheses, we accept the alternative hypothesis and reject the null hypothesis proposed at the start of this research, where the number of gaps in knowledge and behavior increases the incidence of urinary tract infection.

Atuação do enfermeiro na rede básica de saúde frente a gestante com infecção do trato urinário

The Urinary Tract Infection (UTI) in pregnancy is important as a consequence of the high incidence during the gestation. It is the third most common clinical complication in pregnancy affecting 10-12% of women whether prevalence is increasing in the first trimester of pregnancy, it may also contribute to maternal and infant mortality. Due the relevance for the results of obstetric and neonatal complications from UTI, these complications must be prevented, because it can lead to health hazards to pregnant women and newborns, producing a direct effect on morbidity and perinatal mortality. On this basis, it was defined as objectives of this research the identification of the profile of nurses from the Family Health Strategy (FHS) in the East and West Health Districts from the city of Natal / RN before the women with UTI and to verify the nurse performance during prenatal consultations. This is an exploratory study with a quantitative approach using a sample of 40 nurses active workers during this survey, it was approved by the Research Ethics Committee of the Universidade Federal do Rio Grande do Norte Protocol n0 232/10 P-CEP/UFRN and opinion n0 080/2011. The tool for data collection was a structured interview. The data collected were organized into an electronic database application Microsoft ® Excel 2007, exported and analyzed using the Statistical Package for Social Sciences (SPSS) version 17.0, and coded, tabulated and presented through tables and charts into their respective percentage distributions, using the descriptive and inferential statistical analysis, chi-square test and significance level of 5% (distribution in relative and absolute frequencies) in the independent variables. Therefore, it was observed from these results that the longer action of nurses in the FHS from the East and Weast health districts of the city of Natal/RN contributed to the development of a greater number of activities to control the incidence of UTI in women who are attended in the prenatal care service, proven by significance in statistics

Carga de trabalho de enfermagem e infecções relacionadas à assistência à saúde na unidade de terapia intensiva

In recent decades, the search for quality care has been widely discussed by the institutions and health professionals. In this context, it is the nurse coordinator of the process of providing nursing staff, reflecting the commitment to quality of care. In this process, it is the appearance of Infections Related to health care and its potential association with the workload in nursing as a valuable indicator of quality of care. Thus, this research contributes to studies to characterize the demand of nursing work to promote a safe healthcare practice. This study aimed to identify the association of nursing workload with the number of cases of Ventilator-Associated Pneumonia, urinary tract infection and central venous catheter infection in the intensive care unit. This is a quantitative research approach, descriptive, cross-sectional and prospective, held at Unimed Hospital in Natal-RN. The study population consisted of all patients treated in the Intensive Care Unit, Hospital for a period of 90 consecutive days in 2011. The convenience sample was compostapelos patients admitted to the ICU during the period of data collection, a total sample of 286 patients. To perform the data analysis software were used: Statistica 6.0, SPPS (Statistical Package for Social Sciences) version 17.0 (2004) and Excel 2007. In the descriptive analysis, we used Measures of Central Tendency and Measures of Dispersion or Variability and the use of nonparametric tests. Of the 286 patients, 88 were from the ICU and 198 ICU II II. Males predominated in the ICU I (51.1%) and female ICU II (57.6%) patients in the ICU I were aged 61-80 years (39.8%) followed by greater than 80 years (39.8%). In the ICU II, most of the patients were aged 61-80 years (38.9%) and then from 41 to 60 years (24.2%). In relation to the class of TISS inlet predominant class II in the two ICUs (59.1%), followed by Class III also in the two units (34.6%). Most patients (70.6%) out of the ICUs belonging to class II TISS. In the ICU I, the average number of forms of the TISS 28 was 6, has in ICU II this value drops to 3.2 forms. The overall mean was 19.9 TISS points in ICU patients I and ICU II.the 17 points in the average hours required to provide adequate nursing care to patients in the ICU I found that is 10 , 7 hours, and the ICU II 9.2 hours. It was found that the time provided by the nursing staff were higher in ICU II, with an average of 19 hours available for nurses in this sector. In the ICU I, which showed higher need of available hours, it was found that the mean value of 12.7 available hours. It was found that only 2.4% of patients had these units Ventilator-Associated Pneumonia, 1.0% were infected central venous catheter and 1.4% of patients had urinary tract infection. Infection associated with health care occurs, on average, on the tenth day of hospitalization. In the ICU II, this average value extends to the twelfth day with an excess of 2.7 hours of nursing care while in ICU I value decays to the ninth day of hospitalization with a deficiency of 12-hour assistance. It is concluded that patients generally showed a need for classification of semi-intensive care and has been assisted in their need to load. As for his association with the Related Infections Health will assist this analysis could not be performed due to the small number of notifications in this period. It is suggested further study how other factors related to infections me a longer period of analysis

Prevalência de incontinência urinária e fatores associados em idosos institucionalizados

Urinary incontinence (UI) is a geriatric syndrome that is especially prevalent in institutionalized individuals, and that causes economic and social impacts derived from treatment costs and overload of caregiver. UI also entails physical consequences to the health of the elderly, such as urinary tract infections or pressure ulcers, among other health problems. However, the existing national research on this condition is still scarce and comprises serious methodological biases. Therefore, the objective of this study is to determine the prevalence of urinary incontinence and associated factors in institutionalized elderly. A cross-sectional study is presented herein, conducted between October and December, 2013 and carried out in 10 nursing homes in the city of Natal (Northeast Brazil). UI was verified through the program Minimum Data Set version 3.0, which was also used to assess fecal incontinence, urinary devices and UI control programs. Data collection included sociodemographic information, UI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity and Pfeiffer test for cognitive status). Bivariate analysis was performed using the Chi-Square Test (or Fisher‟s Exact Test) and the Linear Chi-Square Test, calculating the prevalence ratio with 95% confidence interval. Variables with p value under 0.20 were included in the multivariate analysis, which was performed using the Stepwise Forward logistic regression. The inclusion of variables in the final model depended on the likelihood ratio test, absence of multicollinearity and on the Hosmer-Lemeshow test. A statistical significance level of 0.05 was considered. Six (1.8%) hospitalized elderly, one individual in palliative care (0.3%) and one (0.3%) individual under the age of 60 were excluded from the study. The final sample consisted of 321 elderly, mostly females, with a mean age of 81.5 years. The prevalence of UI was 59.43% and the final model revealed statistically a significant association between UI and white race, physical inactivity, stroke, mobility constraints and cognitive decline. The most frequent UI type was functional UI due to physical or cognitive disability, and incontinence control measures were applied only to a minority of residents (approximately 8%). It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke and other geriatric syndromes such as immobility and cognitive disability. Most of these associated factors are modifiable and therefore the findings of this study highlight the importance of UI prevention and treatment in nursing homes, which include general measures, such as physical and psychosocial activities, and specific measures, such as prompted voiding

Caracterização de sorotipos em linhagens do gênero Salmonella isoladas de diferentes afecções em animais domésticos

Foram caracterizados os sorotipos, o perfil de sensibilidade microbiana e os achados clínico-epidemiológicos em 53 linhagens do gênero Salmonella isoladas de 41 cães, nove equinos e três bovinos, acometidos por diferentes manifestações clínicas entre 1997 e 2007. Salmonella Typhimurium (45,3%), Salmonella enterica (22,6%), Salmonella Enteritidis (7,5%), Salmonella enterica subsp enterica 4,5,12i (5,7%), Salmonella Newport (5,7%), Salmonella Dublin (3,8%), Salmonella Agona (3,8%), Salmonella Glostrup (3,8%), Salmonella Saintpaul (1,8%) foram os sorotipos encontrados. Ciprofloxacina (100,0%), norfloxacina (100,0%) e gentamicina (100,0%) foram os antimicrobianos mais efetivos, enquanto a maior resistência das linhagens foi observada para ceftiofur (28,5%) e florfenicol (7,0%). As linhagens foram isoladas de animais com enterite, infecção do trato urinário, septicemia, piometra, pneumonia e conjuntivite. Ressalta-se para o predomínio do sorovar Typhimurium nas diferentes manifestações da salmonelose nos animais. Destaca-se, também, a identificação de sorotipos nos animais que também são observados em casos de salmonelose em humanos

Infecção em idosos internados em instituição de longa permanência

OBJETIVO: Avaliar ocorrência de infecção em idosos de instituição de longa permanência (ILP) durante 13 meses consecutivos. MÉTODOS: Cinqüenta e cinco idosos foram avaliados segundo critérios de infecção e de comunicação padronizada. RESULTADOS: A idade mediana foi de 75 (66-81) anos. O conjunto de dados constituiu-se de 20.896 pacientes-dia (PD) durante o período, com um total de 76 infecções para uma taxa média de infecção de 3,2 por 1000 PD. A taxa de pacientes com infecção foi de 63,6%. As topografias prevalentes foram respiratória (50%), trato urinário (32%), pele e partes moles (12%) e gastrintestinal (7%), com taxa de infecção/1000 PD de 1,60; 1,01; 0,38; e 0,2, respectivamente. A taxa de mortalidade por infecção foi de 5%. Agentes microbiológicos foram isolados em 30,5% dos episódios infecciosos e Escherichia coli e Staphylococcus aureus foram os mais freqüentes. CONCLUSÃO: Infecção apresentou elevada incidência nos idosos institucionalizados, porém nenhum evento extraordinário foi observado.

Complications and risk factors in transrectal ultrasound-guided prostate biopsies

CONTEXTO E OBJETIVO: A biópsia da próstata não é um procedimento isento de riscos. Existe preocupação com respeito às complicações e quais seriam os melhores antibióticos usados antes do procedimento. O objetivo foi determinar a taxa de complicações e os possíveis fatores de risco para complicação na biópsia da próstata. TIPO DE ESTUDO E LOCAL: Estudo prospectivo clínico, realizado no Hospital das Clínicas de Botucatu. MÉTODOS: Foram realizadas biópsias em 174 pacientes que apresentavam anormalidade ao exame digital da próstata ou antígeno prostático específico maior que 4 ng/ml ou ambos. Todos os pacientes realizaram enema e antibioticoprofilaxia previamente ao exame. As complicações foram anotadas após o término do procedimento e em consultas posteriores. Algumas condições foram investigadas como possíveis fatores de risco para biópsias de próstata: idade, câncer da próstata, diabetes melito, hipertensão arterial sistêmica, antecedentes de prostatite, uso de ácido acetilsalicílico, volume prostático, número de biópsias e uso de sonda vesical. RESULTADOS: As complicações hemorrágicas foram mais comuns (75,3%) enquanto que as infecciosas ocorreram em 19% dos casos. O tipo mais freqüente foi a hematúria, ocorrendo em 56% dos pacientes. A infecção do trato urinário ocorreu em 16 pacientes (9,2%). Sepse foi observada em três pacientes (1,7%). Não houve óbitos. em 20% dos pacientes não foram observadas complicações após o exame. A presença da sonda vesical foi fator de risco para complicações infecciosas (p < 0,05). O número maior de amostras nas biópsias foi relacionado à hematúria, sangramento retal e complicações infecciosas (p < 0,05). As demais condições investigadas não se relacionaram com complicações pós-biópsia da próstata. CONCLUSÕES: As complicações pós-biópsia da próstata foram em sua maioria autolimitadas. A taxa de complicações graves foi baixa, sendo a biópsia de próstata guiada pelo ultra-som segura e eficaz. A retirada de um maior número de fragmentos na biópsia relaciona-se com hematúria, sangramento retal e complicações infecciosas. A sonda vesical foi um fator de risco para complicações infecciosas.

Factors predictive of inappropriateness in requests for parenteral antimicrobials for therapeutic purposes: A study in a small teaching hospital in Brazil

Background: The identification of patterns of inappropriate antimicrobial prescriptions in hospitals contributes to the improvement of antimicrobial stewardship programs (ASP). Methods: We conducted a cross-sectional study to identify predictors of inappropriateness in requests for parenteral antimicrobials (RPAs) in a teaching hospital with 285 beds. We reviewed 25% of RPAs for therapeutic purposes from y 2005. Appropriateness was evaluated according to current guidelines for antimicrobial therapy. We assessed predictors of inappropriateness through univariate and multivariate models. RPAs classified as 'appropriate' or 'probably appropriate' were selected as controls. Case groups comprised inappropriate RPAs, either in general or for specific errors. Results: Nine hundred and sixty-three RPAs were evaluated, 34.6% of which were considered inappropriate. In the multivariate analysis, general predictors of inappropriateness were: prescription on week-ends/holidays (odds ratio (OR) 1.67, 95% confidence interval (CI) 1.20-2.28, p = 0.002), patient in the intensive care unit (OR 1.57, 95% CI 1.11-2.23, p = 0.01), peritoneal infection (OR 2.15, 95% CI 1.27-3.65, p = 0.004), urinary tract infection (OR 1.89, 95% CI 1.25 -2.87, p = 0.01), combination therapy with 2 or more antimicrobials (OR 1.72, 95% CI 1.15-2.57, p = 0.008) and prescriptions including penicillins (OR 2.12, 95% CI 1.39-3.25, p = 0.001) or 1(st) generation cephalosporins (OR 1.74, 95% CI 1.01-3.00, p = 0.048). Previous consultation with an infectious diseases (ID) specialist had a protective effect against inappropriate prescription (OR 0.34, 95% CI 0.24-0.50, p < 0.001). Factors independently associated with specific prescription errors varied. However, consultation with an ID specialist was protective against both unnecessary antimicrobial use (OR 0.04, 95% CI 0.01-0.26, p = 0.001) and requests for agents with an insufficient antimicrobial spectrum (OR 0.14, 95% CI 0.03-0.30, p = 0.01). Conclusions: Our results demonstrate the importance of previous consultation with an ID specialist in assuring the quality of prescriptions. Also, they highlight prescription patterns that should be approached by ASP policies.

Resultado perinatal de fetos com malformações do trato urinário

PURPOSE: to evaluate the perinatal outcome of fetuses with congenital anomalies of the urinary tract. METHODS: we reviewed the perinatal outcome of 35 fetuses with congenital anomalies of the urinary tract. The following characteristics related to the uropathy were analyzed: type (hydronephrosis, dysplasia and renal agenesis), side of lesion (bilateral or unilateral), and level of the obstruction (high or low, in hydronephrosis). The perinatal outcome was evaluated according to these characteristics. The data were analyzed by the c² test and by the exact Fisher test. The level of significance was 0.05. RESULTS: the incidence of hydronephrosis was 68.6%. Half of the fetuses had unilateral hydronephrosis. Renal dysplasia occurred in 17.1% of the cases; 83.3% of these were bilateral and 16.7%, unilateral. The incidence of renal agenesis was 14.3%, all bilateral. The fetuses with dysplasia/agenesis had a 91% incidence of oligohydramnios, preterm birth, low birth weight, and death. In the group with bilateral disease the presence of oligohydramnios, preterm birth, low birth weight, death, urinary tract infections, and the need of hospitalization for a period greater than 7 days was significant when compared to the group with unilateral disease. The need of hospitalization for a period greater than 7 days in patients with low obstruction was significantly higher when compared to the patients with high obstruction. CONCLUSIONS: hydronephrosis, bilateral disease, and lower obstruction were the most frequent uropathies. The dysplasia/agenesis group had a worse prognosis when compared with the hydronephrosis group. Bilateral disease had a worse prognosis when compared with the unilateral disease group. In the low obstruction group, the need for a period of hospitalization greater than seven days was higher than in the high obstruction group.
