Valore predittivo dei test sierologici nella diagnosi di malattia celiaca
2002
In the diagnostic work-up of celiac disease (CD) the simpler enzyme-linked immunosorbent assay (ELISA) for the identification of serum anti-transglutaminase (tTG) autoantibodies could substitute the immunofluorescence technique used for the detection of anti-endomysial antibodies (EmA). However, most of the studies on anti-tTG assay have considered pre-selected groups of patients and not consecutive subjects with suspected CD. The aim of this study was to compare the sensitivity, specificity and predictive value of anti-gliadin antibodies (AGA), EmA and two anti-tTG ELISAs, one based on guinea pig (gp)-tTG and the other on human (h)-tTG as antigens, in consecutive patients investigated for …
Autonomic Nerve Blocks
1988
Selective block of the sympathetic trunk was first reported by Sellheim and, shortly thereafter, by Lawen, Kappis, and Finsterer (1905–1910). In 1924, reports were published by Brumm and Mandl and by Swertlow. After 1930, the technique and the indications were established by White in the United States and Leriche and Fontaine in Europe.

Fast blue B functionalized silica-polymer composite to evaluate 3,5-dihy-droxyhydrocinnamic acid as biomarker of gluten intake
2021
Celiac disease is an immune-mediated systemic disorder elicited by gluten and related prolamines in genetically susceptible individuals. The current treatment is a strict and lifelong gluten-free diet. However, compliance with the gluten-free diet is not always adequate and many food products contain low concentrations of gluten. The determination of dietary transgressions is a challenge for patients, physicians and dietitians. Alkylresorcinols (AR) have been proposed as sensitive and specific biomarkers of gluten consumption. In this work silica-polymer composites doped with fast blue B reagent (FB) have been used to estimate alkylresorcinols in biological samples. The proposed colorimetri…
Chimney and Periscope Grafts Observed Over 2 Years After Their Use to Revascularize 169 Renovisceral Branches in 77 Patients With Complex Aortic Aneu…
2013
Purpose: To evaluate the performance of periscope and/or chimney grafts (CPGs) in the endovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelf devices. Methods: Between February 2002 and August 2012, 77 consecutive patients (62 men; mean age 7369 years) suffering from pararenal aortic (n¼55), thoracoabdominal (n¼16), or arch to visceral artery aneurysms (n¼6) were treated with aortic stent-graft implantation requiring chimney and/or periscope grafts to maintain side branch perfusion. CPGs were planned in advance and were not used as bailout. A standardized follow-up protocol including computed tomographic angiography, laboratory testing, and clinical examination…
Refractory coeliac disease: one step closer to the origin of aberrant lymphocytes.
2012
Aberrant intraepithelial lymphocytes (IELs) are the key feature of refractory coeliac disease type II (RCDII), but the cellular origin of these aberrant IELs remains unclear. In a recent paper Schmitz et al 1 further explored previously characterised aberrant IEL cell lines from four patients with RCDII by using a broad spectrum of cell specific markers, RNA array and immunological techniques, to compare these cell lines to IELs from the fetal intestine, the intestine of children and adults and the thymus. IELs are a heterogeneous population of lymphocytes with innate and adaptive features that inhabit the small and large intestine. IELs are important for the maintenance of tolerance to com…

Vaccination Status and Attitudes towards Vaccines in a Cohort of Patients with Celiac Disease.
2022
(1) Background: The identification of vaccination status and attitudes towards vaccines among celiac disease (CD) patients is of great importance, but it has not yet been investigated. The aim of this study was to investigate coverage against vaccine-preventable diseases (VPDs), attitudes towards vaccinations, and its determinants among CD patients. (2) Methods: An anonymous web-based validated questionnaire was sent to a mailing list of CD adult patients. Patients were asked to self-report their previous vaccinations and attitudes towards vaccinations, which were defined as positive, negative, and partially positive/negative. The influencing factors towards vaccinations were investigated, …
DETERMINATION OF MACRO ELEMENTS IN GLUTEN-FREE FOOD FOR CELIAC PEOPLE BY ICP-OES
2015
This paper is the first analytical approach to the study of seven nutrients in the gluten-free foods for celiac people. The ICP-OES technique was used. One of the advantages about the use of ICP-OES for this characterization is the high selectivity and low interferences for studied elements. The concentration values of K, Li, Sr, Na, Ca, Mg and Al in seventeen gluten-free food samples are reported. Considering the average concentrations of the elements analyzed, excluding lithium, in the present study it can be concluded that they are inadequate if compared with the recommended daily intake by international organisms, providing only from 1.5 to 20% of the RDI for the essential metals. In pa…
