Pilot study for the evaluation of morphological and functional changes in retinal blood flow in patients with insulin resistance and/or type 2 diabet…
2012
Background: The aim of this study was to investigate early morphological and functional pathology in the retinal micro-circulation in patients with insulin resistance and/or type 2 diabetes mellitus (T2DM). Methods: Fifty-four subjects, without features of retinopathy under ophthalmological investigation, were recruited for study participation and were classifed into three study groups according to their metabolic staging: (1) Group C comprised nondiabetic, insulin-sensitive subjects with a BMI <28kg/m2; (2) Group IR comprised nondiabetic, insulin-resistant, obese subjects with a BMI ≥28 kg/m2; and (3) Group DM comprised patients with manifested T2DM. Retinal microvascular blood flow was…
Functional heartburn has more in common with functional dyspepsia than with non-erosive reflux disease.
2009
Introduction: Functional dyspepsia and non-erosive reflux disease (NERD) are prevalent gastrointestinal conditions with accumulating evidence regarding an overlap between the two. Still, patients with NERD represent a very heterogeneous group and limited data on dyspeptic symptoms in various subgroups of NERD are available. Aim: To evaluate the prevalence of dyspeptic symptoms in patients with NERD subclassified by using 24 h impedance-pH monitoring (MII-pH). Methods: Patients with typical reflux symptoms and normal endoscopy underwent impedance-pH monitoring off proton pump inhibitor treatment. Oesophageal acid exposure time (AET), type of acid and non-acid reflux episodes, and symptom ass…
Cerebral abscesses imaging: A practical approach
2020
Abstract: Brain abscesses (BAs) are focal infections of the central nervous system (CNS) that start as a localised area of weakening of the brain parenchyma (cerebritis) and develops into a collection of pus surrounded by a capsule. Pyogenic (bacterial) BAs represent the majority of all BAs; in some cases, the diagnostic and therapeutic management can be challenging. Imaging has a primary role in differentiating BAs from other lesions. Conventional magnetic resonance imaging (cMRI) is essential for the identification of the lesion, its localisation and its morphological features. However, cMRI does not allow to reliably differentiate BAs from other intracranial mass lesions such as necrotic…
Infliximab in the treatment of Crohn's disease: Predictors of response in an Italian multicentric open study
2005
Abstract Background. Almost 20% of patients with active Crohn's disease are refractory to conventional therapy. Infliximab is a treatment of proven efficacy in this group of patients and it is not clear which variables predict a good response. Aims. To evaluate the role of infliximab looking at the predictors of response in a large series of patients with Crohn's disease. Patients and methods. Five hundred and seventy-three patients with luminal refractory Crohn's disease (Crohn's Disease Activity Index (CDAI) > 220–400) (312 patients) or with fistulising disease (190 patients) or both of them (71 patients) were treated with a dose of 5 mg/kg in 12 Italian referral centres. The primary endp…
Evoked otoacoustic emissions and pure tone threshold audiometry in patients receiving cisplatinum therapy.
1993
Eight children and young adults with cancer were evaluated serially using pure tone audiometry as well as registration of click-evoked otoacoustic emissions (EOAE) 1 day prior to therapy as well as after various numbers of doses of cisplatinum. A reduction of EOAE-amplitudes following cisplatinum therapy was observed in all patients. This reduction tended to recover after the end of cisplatinum administration. Since EOAE are believed to result from cochlear bio-mechanical processes, the reduced emissions are interpreted as signs of cochlear dysfunction. We conclude, that EOAE testing may be a simple, non-invasive method that may detect early, transient functional impairment of hearing due t…
Functional signs in patients consulting for presumed Lyme borreliosis
2019
Little is known about the functional symptoms associated with Lyme borreliosis (LB) in Europe. We aimed to assess functional symptoms associated with presumed LB and to compare patients with and without confirmed LB.We performed a retrospective monocenter study. Patients consulting for presumed LB were included.Between November 2015 and June 2018, 355patients were included (mean age: 51years, 52% of women) of which 48had LB: erythema migrans (42%), early disseminated LB (50%; 35% of neuroborreliosis cases), and late disseminated LB (8%). The most frequently reported functional symptoms were neuropathic pain (23%), arthralgia (23%), and asthenia (17%). Other functional symptoms were rare (≤1…
Capsule Endoscopy versus Push Enteroscopy in Patients with Occult Gastrointestinal Bleeding
2003
Background Wireless capsule endoscopy is a new method enabling non-invasive diagnostic endoscopy of the entire small intestine. In this study we prospectively examined the diagnostic precision of capsule endoscopy compared with push enteroscopy in patients with occult gastrointestinal bleeding. Methods Between July 2001 and October 2002 we examined 48 patients with suspected disorders of the small intestine using capsule endoscopy. 33 patients with obscure bleeding (19 men, 14 women, mean age 58 +/- 23 years) were prospectively examined using capsule endoscopy and push enteroscopy. Results On average, the patients had been suffering from chronic gastrointestinal bleeding for 30 +/- 36 (1-12…
Influence of Patient Selection on the Outcome of Capsule Endoscopy in Patients With Chronic Gastrointestinal Bleeding
2005
Background: In chronic gastrointestinal bleeding, success rates in the range of 48% to 76% have been reported for diagnosing clear bleeding sources using capsule endoscopy. The influence of patient selection on the numbers of positive findings yielded by capsule endoscopy is as yet unclear. Methods: From April 2001 to June 2003, capsule endoscopy was carried out in 74 of a total of 127 patients (58%) who presented for capsule endoscopy with a high suspicion of gastrointestinal bleeding in the small-bowel region. Seventy of the 74 patients were included in the analysis. This group of patients was divided into a study group (32 patients) and a post-study group (38 patients), and the two group…
Personality disorders among the relatives of schizophrenia patients.
1994
In light of current linkage studies in schizophrenia, research on the "schizophrenia spectrum" deserves increased attention for an exact determination of the affected phenotype: Those disorders that have a much higher prevalence among biological relatives of schizophrenia patients are supposed to share common etiological factors with "core" schizophrenia. However, there is controversy over which of the DSM-III-R personality disorders should be included in the spectrum. In a controlled family study of inpatients with a DSM-III-R diagnosis of schizophrenia (n = 101), schizophreniform and schizoaffective disorders (n = 69), and unipolar major depression (n = 160), familial rates of personality…
Diagnosis of culture-negative endocarditis: The role of the Duke criteria and the impact of transesophageal echocardiography
2001
Abstract Background The Duke criteria have been shown to be more sensitive than the von Reyn criteria in the diagnosis of culture-positive endocarditis but to date have not been fully validated for culture-negative endocarditis (CNE). The aim of this study was (1) to compare the diagnostic accuracy of the Duke criteria versus clinical judgment and the von Reyn criteria in CNE and (2) to assess the diagnostic impact of transesophageal echocardiography (TEE) on the Duke criteria in CNE. Methods The study group consisted of 49 patients with suspected CNE in whom the presence (n = 32) or absence (n = 17) of endocarditis was confirmed by surgery, autopsy, or both. All patients underwent transtho…
