Diagnostic accuracy of fecal elastase 1 assay in patients with pancreatic maldigestion or intestinal malabsorption: a collaborative study of the Ital…
2001
Several reports have indicated that fecal elastase-1 (EL-1) determination is a new, sensitive, and specific noninvasive pancreatic function test; however, very few patients with malabsorption due to small intestine diseases have been included in the previous studies. The aim of the study was to compare the diagnostic accuracy of fecal EL-1 and fecal chymotrypsin (FCT) in distinguishing between pancreatic maldigestion and intestinal malabsorption. Three groups of subjects were studied: group A included 49 patients with known cystic fibrosis (25 males, median age 5 years); group B included 43 subjects with various small intestine diseases (17 males, median age 6 years); and group C included 4…
A comparison between two different in vitro basophil activation tests for gluten- and cow's milk protein sensitivity in irritable bowel syndrome (IBS…
2013
Abstract Background: The diagnosis of food hypersensitivity (FH) in adult patients with gastrointestinal symptoms, beyond the immediate IgE-mediated clinical manifestations, is very often difficult. The aims of our study were to: 1) evaluate the frequency of FH in patients with irritable bowel syndrome (IBS)-like clinical presentation; and 2) compare the diagnostic accuracy of two different methods of in vitro basophil activation tests. Methods: Three hundred and five patients (235 females, age range 18–66 years) were included and underwent a diagnostic elimination diet and successive double-blind placebo-controlled (DBPC) challenges. Two different methods of in vitro basophil activation te…
Relationship between specific serum IGE to Ascaris lumbricoides and onset of respiratory symptoms in Bangladesh immigrants
2006
The role of helminths in asthma and/or rhinitis and in allergic sensitization is still unclear. We assessed the relationship between Ascaris-specific IgE, respiratory symptoms and allergic sensitization in Bangladesh immigrants. 246 individuals were examined from 1996 to 2001. Serum total IgE, Ascaris IgE, specific IgE to inhalant allergens, skin prick tests (SPT) and parasitological evaluation of the stool were performed. Total serum IgE were significantly higher in Ascaris-IgE positive (> 0.35 kU/L) individuals (806.5 [409.0–1436.0] kU/L vs. 207.0 [127.0–332.5] kU/L; P < 0.0001) and in subjects with respiratory symptoms (413.0 [239.0–1096.0] kU/L vs. 259.5 [147.0–387.0] kU/L), ( P …
Cognitive and social impairments in patients with superficial siderosis
2005
Superficial siderosis of the CNS is a rare condition, caused by deposition of haemosiderin in the superficial layers of the CNS due to repeated chronic subarachnoid or intraventricular haemorrhage. Typically, the hindbrain structures, especially the cerebellum, are most affected. There is a surprising lack of studies investigating in detail the behavioural functioning of patients with such a condition. In this study, we document for the first time the cognitive, social and emotional processing of six patients with a confirmed clinical diagnosis of superficial siderosis. They were aged between 40 and 62 years, with a mean age of 50.2 years; four were male. We administered a comprehensive bat…
Psychophysiological and vocal measures in the detection of guilty knowledge.
2004
The Guilty Knowledge Test (GKT) and its variant, the Guilty Actions Test (GAT), are both psychophysiological questioning techniques aiming to detect guilty knowledge of suspects or witnesses in criminal and forensic cases. Using a GAT, this study examined the validity of various physiological and vocal measures for the identification of guilty and innocent participants in a mock crime paradigm. Electrodermal, respiratory, and cardiovascular measures successfully differentiated between the two groups. A logistic regression model based on these variables achieved hit rates of above 90%. In contrast to these results, the vocal measures provided by the computerized voice stress analysis system …
Oral lichenoid lesions associated with amalgam restorations : a prospective pilot study addressing the adult population of the Basque Country
2011
Oral lichenoid lesions (OLLs) are linked to a heterogeneous group of pathologies involving the oral mucosa that cannot be distinguished from the oral lichen planus excepting the fact that direct causal factors such as silver amalgam restorations (SARs) can be allocated to them. Purpose: To analyze the prevalence of mucosal lesions associated with SAR in a group of SAR carrying patients in the Basque Country. Study D esign: A clinical prospective study was carried out on 100 adult patients over 30 years of age at the UPV/ EHU Clinical Odontology Service whose rear teeth had at least one SAR. Patients were identified and mucosal lesions and amalgam restorations were characterized. Patch tests…
Genotoxicity of selected pesticides in the mouse bone-marrow micronucleus test and in the sister-chromatid exchange test with human lymphocytes in vi…
1996
Selected pesticides (aldicarb, 1,3-dichloropropene, methidathion, parathion, triadimefon, vinclozolin) were tested for their clastogenic and aneugenic activities in the mouse bone-marrow micronucleus (MN) test in vivo and for their sister-chromatid exchange-inducing activities in human lymphocytes in vitro in the presence and absence of an exogenous metabolizing system from rat-liver S9. 1,3-Dichloropropene significantly increased the frequencies of micronucleated polychromatic erythrocytes (PCE) in bone-marrow cells of female mice from 3.3 MN/1000 PCE to 15.3 MN/1000 PCE (187 mg per kg body weight). 1,3-Dichloropropene (100 microM) induced 16.0 SCE/metaphase after 24 h of incubation as com…
Moral reasoning and moral conflict in patients of the amyotrophic lateral sclerosis – Frontotemporal dementia spectrum
2020
The aim of this study was to investigate the moral reasoning and moral conflict in patients of the amyotrophic lateral sclerosis – frontotemporal dementia (ALSFTD) spectrum. Ten ALS patients without cognitive impairment, 10 ALS patients with cognitive or behavioral impairment, 10 ALSFTD patients and 23 controls were examined with neuropsychological and behavioral tests as well as with a set of eight well -designed moral dilemmas. The responses to the moral dilemmas were used as proxies to evaluate interpersonal moral reasoning. Reactivity to change, reaction time and arousal were used as markers of moral conflict. ALSFTD patients showed more “utilitarian” responses and less moral conflict t…
Association of Type D personality with cognitive functioning in individuals with and without cardiovascular disease: The Gutenberg health study
2016
ObjectiveDistressed (‘Type D’) personality is associated with adverse health outcomes in patients with cardiovascular disease (CVD). While personality traits from the Five-Factor Model are related to cognitive functioning, neither Type D personality nor its underlying traits negative affectivity (NA) and social inhibition (SI) have been investigated regarding cognition. We therefore compared the predictive value of Type D classification and its subcomponents NA and SI on planning performance in individuals with and without CVD.MethodsType D personality traits (DS14) were determined in a population-based sample of 4026 participants (including 549 with CVD) aged 40–80 years from the Gutenberg…
Speech Perception: Phonological Neighborhood Effects on Word Recognition Persist Despite Semantic Sentence Context
2019
This study tested the hypothesis that two lexical properties, both phonological neighborhood density (ND) and neighborhood frequency (NF), influence the recognition of target words when preceded by either a semantically congruent or semantically neutral context. Our study is the first to test this hypothesis using a language other than English (i.e., Spanish). We used highly familiar bisyllabic nouns with medium-frequency occurrence as target words, and we expected recognition accuracy to increase as ND and NF decreased in both semanticallly congruent and semantically neutral sentences. We presented 48 undergraduate listeners with a set of 80 words, differing in ND and NF, within these two…
