Usefulness of complementary test in the study of patients with chronic abdominal pain.
2021
Introduction: Chronic abdominal pain (CAP) in children is a symptom that frequently leads to a visit to the paediatrician, which affects family life and occasionally requires the need to perform diagnostic studies (DS). The objective was to carry out a qualitative, quantitative, and economic analysis on the tests requested. Material and methods: An observational, prospective and multicentre study was conducted that included children between 4–15 years old affected by CAP. The difference between organic and functional disorders was taken into account. The following variables were collected: history, warning signs and symptoms, DS, and the cost of these. Results: The study included 235 childr…
Diagnostics of autoimmune bullous diseases in German dermatology departments
2012
Summary Background: No consistent data are available on the currently employed diagnostic tools for autoimmune bullous diseases in Germany. The aim of this survey was to describe currently performed diagnostic methods for bullous autoimmune diseases in German dermatology departments. Methods: A standardized questionnaire evaluated the available diagnostic methods i. e. direct immunofluorescence microscopy (IFM), indirect IFM, commercial ELISA systems, and non-commercial serological tests as well as the number of samples per year in all 34 university and 39 non-university dermatology departments. Results: The overall return rate was 89 %, 100 % and 79 % for the university and non-university …
Acceptability of virtual reality interoceptive exposure for the treatment of panic disorder with agoraphobia
2013
Interoceptive exposure (IE) is a standard component of cognitive-behavioural therapy (CBT) for panic disorder and agoraphobia. The virtual reality (VR) program ‘Panic-Agoraphobia’ has several virtual scenarios designed for applying exposure to agoraphobic situations; it can also simulate physical sensations. This work examines patients' acceptability of the IE component as applied in two different ways: using VR versus traditional IE. Additionally, it explores the relationship between users' treatment expectations and satisfaction and clinically significant change. Results showed that VR and traditional IE were well accepted by all participants. Furthermore, treatment expectations predicted…
Reliability of automatic detection of AHI during positive airway pressure treatment in obstructive sleep apnea patients: A “real-life study”
2021
Introduction: Automatic event detection (AED) of residual apnea-hypopnea index (AHI) by ventilators is a current practice in sleep and mechanical ventilation Units but this methodology has not been validated in an unselected population of OSA patients. Aim of the present study was to assess in a “real-life” condition the reliability of AED during PAP therapy by the in-built software compared to full polysomnography during follow-up. Methods: We enrolled 300 OSA patients (105 F; AHI 45.3 ± 27.8) already on Positive airway pressure (PAP) therapy: 53% of the patients were on CPAP while other modalities were used in the rest of the sample. Results: Overall, the built-in software identified resi…
Termographic survey and architectural envelopes: infrared tecnology to conserve the skin of monuments. Experimental application in Sicily (2002-2009)
2010
The paper treats the elaboration system to obtain a thermogrammetry. The experimental method is useful to get a metric thermal image to be edited with the photogrammetric image of the architectural surfaces simultaneously. This way, the gotten graph can be imported in c.a.d. software as raster image and becomes the base to improve the design of the thematic maps that constitute the restoration project. The essay shows the editing practice to be developed in order to get the diagnosis supported by thermography on the architectural surfaces. Some application examples of the diagnostic methodology are introduced and critically commented to understand all the potentialities of the investigation…
Predicting risk and outcomes for frail older adults: a protocol for an umbrella review of available frailty screening tools
2015
REVIEW QUESTION / OBJECTIVE The aim of this systematic review is to comprehensively search the available literature and to summarize the best available evidence from systematic reviews in relation to published screening tools to identify pre-frailty and frailty in older adults, that is: (i) to determine their psychometric proprieties; (ii) to assess their capacity to detect pre-frail and frail conditions against established methods; and (iii) to evaluate their predictive ability. More specifically, the review will focus on the following questions: - What is the reliability and validity of existing screening tools that assess pre-frailty/frailty in older patients? - How sensitive and specif…
Quantification of Salmonella spp., Listeria monocytogenes and Escherichia coli O157:H7 in non-spiked food products and evaluation of real-time PCR as…
2011
Abstract Escherichia coli O157:H7, Listeria monocytogenes and Salmonella spp. are foodborne pathogens frequently associated with foods such as poultry, ready-to-eat products, fruits and vegetables. PCR-based procedures are rapid, sensitive and accurate; in particular, real-time PCR (qPCR), which besides being an automated high-throughput technique, allows quantification of foodborne pathogens. In the present work, qPCR-based methods were applied for the quantitative detection of E. coli O157:H7, Salmonella spp. and L. monocytogenes in a total of 306 non-spiked food samples in a study carried out in two laboratories simultaneously. qPCR allowed the detection of the three pathogens in around …
The Expertise in the Real Estate Appraisal in Italy.
2014
The study focuses on real estate expertise in Italy considering: the market surface ratios, proposing a series of tests designed to predict the influence of these surfaces on the result of the valuation; and the coefficients of the not surface characteristics providing a measure of the estimation error induced by their use. Overall, the study aims to bring out on a rational level the deficiencies, inaccuracies and errors of the valuations based on the expertise when it is applied to the real estate market. In Italy the application of valuation standard is in the early stages of launching.
An Instrument-Assisted coracoid pain test: an exploratory diagnostic accuracy study
2022
The coracoid pain test (CPT) could contribute to the diagnosis of frozen shoulder (FS) with palpation. However, due to assessor performance these values might be unreliable. Therefore, the aim was to explore the diagnostic accuracy of an instrument-assisted CPT and two alternative approaches (pain severity and side comparison) for assistance in the diagnosis of FS. Patients with FS and healthy age-matched controls were recruited. All participants underwent the instrument-assisted CPT on both shoulders with a pressure algometer. Sensitivity, specificity, and likelihood ratios were determined for the three approaches. In total, 35 patients with FS and 35 healthy participants were included. Th…
The Multivariate Individual Selection of Diagnostic Tests and the Reserved Diagnostic Statement: An Optimum Combination of Two New Methods for the Co…
1984
A combination of two new methods for the diagnostic procedure in computer-aided differential diagnosis is presented. It is constructed on the basis of new results of our own in the field of mathematical decision theory and is demonstrated by the differential diagnosis of congenital heart diseases by means of ECG features.
