Population-based screening for early detection and treatment of colorectal cancer (CRC) and precursor lesions, using evidence-based methods, can be effective in populations with a significant burden of the disease provided the services are of high quality. Multidisciplinary, evidence-based guidelines for quality assurance in CRC screening and diagnosis have(More)
OBJECTIVE To estimate the cumulative risk of a false-positive screening result in European mammographic screening programmes, and examine the rates and procedures of further assessment. METHODS A literature review was conducted to identify studies of the cumulative risk of a false-positive result in European screening programmes (390,000 women). We then(More)
We conducted an investigation of two outbreaks of poliomyelitis in Angola during 2007-2008 due to wild poliovirus (WPV) genetically linked to India. A case-control study including 27 case-patients and 76 age- and neighborhood-matched control-subjects was conducted to assess risk factors associated with paralytic poliomyelitis, and epidemiologic links to(More)
OBJECTIVES To present an analysis of the Department of Paediatrics' statistics on hospital mortality, covering the period through 1980-1990. METHODS Basic information was recollected from logbooks of the Department's wards. Descriptive statistics are estimated on death and its main causes. The proportion of deaths in relation to total admissions and in(More)
OBJECTIVES To summarize participation and coverage rates in population mammographic screening programmes for breast cancer in Europe. METHODS We used the European Network for Information on Cancer (EUNICE), a web-based data warehouse (EUNICE Breast Cancer Screening Monitoring, EBCSM) for breast cancer screening, to obtain information on programme(More)
Between January and June 1999, 1,100 suspected cases of poliomyelitis were reported in Angola. Poliovirus types 3 and 1 were isolated. Patients' ages ranged from 2 months to 14 years. Of the 588 patients whose vaccine status was known, 58 (9.9%) received >4 doses, 216 (36.7%) received 3 or 4 doses, 178 (30.3%) received 1 or 2 doses, and 136 (23.1%) had no(More)
In this study, we analyzed the antimicrobial resistance properties and T antigenic types of 511 isolates collected in Lisbon district, Portugal, from throat swabs of healthy subjects (n=341), during 2000-2002 and from diverse infection sites (n=170) of outpatients and inpatients, during 1999-2002. Erythromycin resistance was higher in(More)
INTRODUCTION As the polio eradication effort enters the end game stage, surveillance for Acute Flaccid Paralysis in children becomes a pivotal tool. Thus given the gaps in AFP surveillance as identified in the cases of late notification, this study was designed to explore the reasons and circumstances responsible for late notification of AFP and collection(More)
The asymptomatic oropharyngeal colonization rate by Streptococcus pyogenes was 10.7% in children (901 among 8,405 children 0–16 years old) and 3.3% in adults (37 among 1,126 households of children) in the Lisbon area during 2000–2006. Macrolide-resistant S. pyogenes from children (n = 149) was variable with time: 9.8–10.7% in 2000–2002, 28.1% in 2003,(More)
