The knowledge and expectations of parents about the role of antibiotic treatment in upper respiratory tract infection – a survey among parents attending the primary physician with their sick child

BACKGROUND: Upper respiratory tract infections (URTI) are common. The etiologic factor is usually viral, but many physicians prescribe antibiotics. We aimed to evaluate parents' expectations of and knowledge about the role of antibiotics in childhood URTI. METHODS: The study was conducted in thirteen primary care pediatric clinics. Parents of children aged 3 months to 6 years who attended with URTI symptoms were included when it was the first attendance in the current illness. Questionnaire about the current illness, reasons for attending and expectations from the visit, knowledge about URTI was filled before the visit. RESULTS: In 122 visits the average age was 2.8 ± 1.9 years. The main reasons for the visit were to avoid complications (81%) and to be examined (78%). Expected treatment was: cough suppressants (64%), anti-congestants (57%), paracetamol (56%), natural remedies (53%) and antibiotics (25%). In 28% the child had received antibiotics in past URTI. Only 37% thought that antibiotics would not help in URTI and 27% knew that URTI is a self-limited disease. 61% knew that URTI is a viral disease. Younger parental age and higher education were associated with lower expectations to receive antibiotics (p = 0.01, p < 0.005 respectively). While previous antibiotic treatment (p < 0.001), past perceived complications (p = 0.05) and the thought that antibiotics help in URTI (p < 0.001) were associated with a greater expectation for antibiotics. CONCLUSIONS: A quarter of the parents attending the physician with URTI are expecting to get antibiotics. Predictors were lower education, older parental age, receiving antibiotics in the past and the belief that antibiotics help in URTI

The Combined Dexamethasone/CRH Test (DEX/CRH Test) and Prediction of Acute Treatment Response in Major Depression

In this study the predictive value of the combined dexamethasone/CRH test (DEX/CRH test) for acute antidepressant response was investigated. In 114 depressed inpatients suffering from unipolar or bipolar depression (sample 1) the DEX/CRH test was performed at admission and shortly before discharge. During their stay in the hospital patients received different antidepressant treatment regimens. At admission, the rate of nonsuppression (basal cortisol levels >75.3 nmol/l) was 24.6% and was not related to the later therapeutic response. Moreover, 45 out of 114 (39.5%) patients showed an enhancement of HPA axis function at discharge in spite of clinical improvement. In a second sample, 40 depressed patients were treated either with reboxetine or mirtazapine for 5 weeks. The DEX/CRH test was performed before, after 1 week, and after 5 weeks of pharmacotherapy. Attenuation of HPA axis activity after 1 week was associated with a more pronounced alleviation of depressive symptoms after 5-week mirtazapine treatment, whereas downregulation of HPA system activity after 5 weeks was related to clinical response to reboxetine. However, early improvement of HPA axis dysregulation was not necessarily followed by a beneficial treatment outcome. Taken together, performance of a single DEX/CRH test does not predict the therapeutic response. The best predictor for response seems to be an early attenuation of HPA axis activity within 1 or 2 weeks. However, early improvement of HPA system dysfunction is not a sufficient condition for a favourable response. Since a substantial part of depressive patients display a persistence of HPA axis hyperactivity at discharge, downregulation of HPA system function is not a necessary condition for acute clinical improvement either. Our data underline the importance of HPA axis dysregulation for treatment outcome in major depression, although restoration of HPA system dysfunction seems to be neither a necessary nor a sufficient determinant for acute treatment response

Perfil de prescrições e uso de antibióticos em infecções comunitárias Prescription patterns and antibiotic use in community-based infections

INTRODUÇÃO: O objetivo deste estudo foi conhecer os padrões de utilização de antibióticos no município de Sorocaba, avaliando o diagnóstico referido, a terapêutica empregada e sua utilização. MÉTODOS: Utilizou-se um instrumento de avaliação aplicado por 12 meses em usuários de antibióticos. Foram coletados dados de 403 usuários e referiram-se à: informações sociodemográficas e de saúde, diagnóstico e terapêutica. RESULTADOS: Encontrou-se grande utilização e a maior utilização prévia na faixa etária de 0-10 anos (p<0,05). As infecções com envolvimento pulmonar foram as mais citadas (p<0,05) e as penicilinas, os fármacos mais utilizados, presentes em 45,1% das prescrições. Tempo médio de terapêutica (8,9 dias) esteve abaixo do preconizado para otites. Em sinusites, 22% das prescrições não orientaram para o uso recomendado (10 dias). CONCLUSÕES: A inexistência e não utilização de protocolos terapêuticos têm resultado em grande diferença nos padrões de prescrição, levando a insucesso terapêutico e recidiva de infecções - situações frequentemente encontradas neste estudo.<br>INTRODUCTION: The aim of this study was to find out about the patterns of antibiotic use in the municipality of Sorocaba, through evaluating the reported diagnosis and the therapy used. METHODS: An evaluation tool was applied among antibiotic users over a 12-month period. Sociodemographic data and information relating to health, diagnosis and therapeutics were gathered in relation to 403 users. RESULTS: Great present use and the greatest previous use was found in the 0-10 year-old age group (p < 0.05). Infections with lung involvement were the ones most mentioned (p < 0.05) and penicillins were the drugs most used, present in 45.1% of the prescriptions. The mean duration of therapy for otitis (8.9 days) was below the recommendation. For sinusitis, 22% of the prescriptions did not give guidance regarding recommended use (10 days). CONCLUSIONS: The lack and/or nonuse of therapeutic protocols resulted in great differences in prescription patterns, thereby leading to therapeutic failure and recurrence of infections, which were situations frequently found in this study
