Newborn screening of inherited metabolic disorders by tandem mass spectrometry: past, present and future
2013
Inborn errors of metabolism are inherited biochemical disorders caused by lack of a functional enzyme, transmembrane transporter, or similar protein, which then results in blockage of the corresponding metabolic pathway. Taken individually, inborn errors of metabolism are rare. However, as a group these diseases are relatively frequent and they may account for most of neonatal mortality and need of health resources. The detection of genetic metabolic disorders should occur in a pre-symptomatic phase. Recently, the introduction of the tandem mass spectrometric methods for metabolite analysis has changed our ability to detect intermediates of metabolism in smaller samples and provides the mea…
Feasibility and diagnostic performance of including point-of-care ultrasound (POCUS) in preparticipation screening of young competitive athletes
2020
AbstractOptimal pre-participative screening in young athletes is still controversial. We sought to evaluate the strategy of including point-of-care ultrasound to electrocardiogram. In total, 1188 young competitive athletes were screened in different sports institutions. This proved to be a useful strategy by improving diagnostic performance primarily with respect to detect structural abnormalities and also by minimising positive false cases of electrocardiogram alone.
Evaluation of C-Reactive Protein in Primary and Secondary Prevention
2007
Inflammation is pivotal in atherosclerosis, and C-reactive protein (CRP) is an inflammatory marker that predicts cardiovascular events. Several population-based studies have demonstrated that baseline CRP levels predict future cardiovascular events. CRP testing may thus have a major adjunctive role in the global assessment of cardiovascular risk. Recently, the National Cholesterol Education Program, through the Adult Treatment Panel III guidelines, identified CRP and another marker of inflammation, the fibrinogen, as “emerging risk factors,” suggesting that their measurement may improve the estimations of absolute risk obtained using the traditional cardiovascular risk factors. In terms of…
Are we able to reduce the mortality and morbidity of oral cancer; Some considerations
2012
Oral cancer makes up 1%-2% of all cancers that may arise in the body. The majority of oral cancers consists of squamous cell carcinomas. Oral cancer carries a considerable mortality rate, being mainly dependent on the stage of the disease at admission. Worldwide some 50% of the patients with oral cancer present with advanced disease. There are several ways of trying to diagnose oral cancer in a lower tumor stage, being 1) mass screening or screening in selected patients, 2) reduction of patients’ delay, and 3) reduction of doctors’ delay. Oral cancer population-based screening (“mass screening”) programs do not meet the guidelines for a successful outcome. There may be some benefit when foc…

Additive effect of factors related to assisted conception on the reduction of maternal serum pregnancy-associated plasma protein A concentrations and…
2013
Objective To analyze whether assisted conceptions need adjustments in first-trimester Down syndrome screening and why modifications in screening markers occur. Design Eleven-year cohort retrospective analysis. Setting Maternal-fetal medicine unit. Patient(s) Two thousand eleven naturally conceived normal singleton pregnancies and 2,042 normal singleton pregnancies achieved with assisted conception: 350 by IUI and 1,692 with IVF (n = 328) or intracytoplasmic sperm injection (ICSI; n=1,364), using nondonor (n = 1,086) or donated ova (n = 606), with fresh (n = 1,432) or frozen (n = 260) embryos. Intervention(s) Comparison of ultrasound and biochemical markers of first-trimester Down syndrome s…
The use of clinical guidelines for referral of patients with lesions suspicious for oral cancer may ease early diagnosis and improve education of hea…
2010
UNLABELLED Early diagnosis and referral of oral cancer is essential. Successful implementation of clinical guidelines must include current practitioners and students. OBJECTIVE To evaluate the diagnostic accuracy of students at oral cancer screening and to assess the effectiveness of clinical referral guidelines. STUDY DESIGN Fifth year dental students were randomly allocated to either control (n=19) or experimental groups (n = 18). Both received the customary training in oral diagnosis. The experimental group underwent a 2 hour workshop where the guidelines for the referral of suspicious lesions were discussed. Three months later, a set of 51 clinical cases including benign, malignant, and…
Saliva as a testing sample for SARS-CoV-2 detection by RT-PCR in low prevalence community settings
2021
AbstractObjectivesThe number of COVID-19 cases is increasing globally and there is an urgency for a simple non-invasive method for the detection of SARS-CoV-2. Our study aimed to demonstrate that saliva can be used as a specimen for SARS-CoV-2 detection notably for the screening of extensive population groups via pooling.MethodsTo demonstrate that saliva is an appropriate specimen for SARS-CoV-2 detection a field study including 3,660 participants was performed between September 29 and October 1, 2020. We collected paired nasopharyngeal/oropharyngeal swabs (NPS) and saliva specimens and processed them within 24 hours of collection. We performed 36 serial measurements of 8 SARS-CoV-2 positiv…
Screening for colorectal cancer with immunochemical faecal occult blood tests.
2012
Population-based studies have shown that guaiac faecal occult blood testing followed by colonoscopy in case of positivity can reduce colorectal cancer mortality. However these tests have been criticised for their fairly low sensitivity. For this reason attention has been given to alternative tests. The aim of this paper is to review the evidence for screening for colorectal cancer using qualitative immunochemical faecal occult blood tests. For the complete range of tested cut-off values, immunochemical faecal occult blood tests lead to higher diagnostic yield, improved sensitivity and greater participation. The optimal number of samples and the optimal cut-off value has to suit local resour…
Investigation and management of Toxoplasma gondii infection in pregnancy and infancy: a prospective study.
2011
Aim:Toxoplasma gondii infection during pregnancy poses a serious risk to the fetus, therefore timely and accurate diagnosis is essential. The aim of this study was to estimate the frequency of congenital infection via evaluating mother's immunological status and the possibility to improving the diagnostic and therapeutic approaches.Methods:Eighty five mothers with Toxoplasma seroconversion and their offspring were enrolled (among them, 2 spontaneous abortions were documented in the first trimester). Prenatal PCR diagnosis was carried out on 50 patients (60%), with 7 positive cases (14%). Morphological ultrasound scanning revealed anomalies in one fetus. Long-term follow-up included general …
