Altered glutathione system is associated with the presence of distal symmetric peripheral polyneuropathy in type 2 diabetic subjects.
2015
Abstract Distal symmetric peripheral polyneuropathy (DSPN) is a highly prevalent complication of diabetes. However, underlying pathophysiological mechanisms are multiple and not well understood. The aim of our study was to analyze the oxidative stress levels in circulating mononuclear cells by measuring the glutathione system, malondialdehyde and oxidized-LDL, in 60 type 2 diabetic patients from a well-characterized cohort of 196 type 2 diabetic patients. Using a nested case–control design, we studied 30 type 2 diabetic patients with distal symmetric polyneuropathy and 30 diabetic controls without this complication, according to the Neuropathy Disability Score. We have found that diabetic p…
Risk Factors for Classical Kaposi Sarcoma in a Population-based Case-control Study in Sicily
2008
Abstract Background: Classical Kaposi sarcoma is a rare complication of Kaposi sarcoma-associated herpes virus (KSHV) infection. We conducted a population-based, frequency-matched case-control study in Sicily to further investigate the reported inverse relationship between smoking and classical Kaposi sarcoma and to identify other factors associated with altered risk. Methods: All incident, histologically confirmed classical Kaposi sarcoma cases in Sicily were eligible. A two-stage cluster sample design was applied to select population controls. KSHV seropositivity was determined using four antibody assays (K8.1 and orf73 enzyme immunoassays and two immunofluorenscence assays). Using SAS-ca…
Evidence for the importance of the human dopamine transporter gene for withdrawal symptomatology of alcoholics in a German population
2002
Two new polymorphisms in the 3' untranslated region (3'UTR) of the dopamine transporter (DAT1) gene, adjacent to the known variable number of tandem repeats (VNTR) polymorphism, have been investigated in the present population-based association study including 351 alcoholics and 336 controls. The DraI restriction site was not polymorphic in our population. The G2319A polymorphism was not significantly different with respect to genotype or allele distribution between alcoholics and controls. Subsequently, in individuals with VNTR homozygosity for the ten repeat allele, we found a higher prevalence of A/A homozygosity in patients with seizure history (P = 0.001, odds ratio (OR) = 7.913), with…
Effects of mat characteristics on plantar pressure patterns and perceived mat properties during landing in gymnastics.
2011
Shock absorption and stability during landings is provided by both, gymnast ability and mat properties. The aims of this study were to determine the influence of different mat constructions on their energy absorption and stability capabilities, and to analyse how these properties affect gymnast's plantar pressures as well as subjective mat perception during landing. Six mats were tested using a standard mechanical drop test. In addition, plantar pressures and subjective perception during landing were obtained from 15 expert gymnasts. The different mats influenced plantar pressures and gymnasts' subjective perception during landing of gymnasts. Significant correlations between plantar pressu…
Symptom-Triggered versus Standard Chlormethiazole Treatment of Inpatient Alcohol Withdrawal: Clinical Implications from a Chart Analysis
2003
To evaluate clinical effectiveness and safety of 2 different detoxification treatment protocols, a chart analysis of hospital inpatients consecutively admitted for alcohol withdrawal during one year was undertaken. Records of 33 patients receiving symptom-triggered treatment (using a modified version of the revised Clinical Institute Withdrawal Assessment for Alcohol Scale) were compared with those of patients treated by applying a fixed-dose regimen (n = 32). Patients (45.3 ± 9.8 years, 21% female) of both groups were comparable regarding illness severity, epidemiologic parameters as well as complications during the observed treatment period. Under symptom-triggered therapy, chlormethiazol…
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…
Enhancing the efficacy of treatment for temporomandibular patients with muscular diagnosis through cognitive-behavioral intervention, including hypno…
2011
Objective This study evaluated the efficacy of a cognitive-behavioral therapy (CBT), including hypnosis, in patients with temporomandibular disorders (TMDs) with muscular diagnosis. Study Design Seventy-two patients (65 women and 7 men with an average age of 39 years) were selected according to the Research Diagnostic Criteria for TMD, and assigned to the experimental group (n = 41), receiving the 6-session CBT program, and the control group (n = 31). All patients received conservative standard treatment for TMD. The assessment included pain variables and psychologic distress. Results There were significant differences between the groups, the experimental group showing a higher improvement …
Masseter reflex and blink reflex abnormalities in Chiari II malformation.
2001
Masseter reflex and blink reflex were evaluated in 64 patients with a myelomeningocele and Chiari II malformation. In 46 patients, no brainstem signs or symptoms were present. Brainstem dysfunction related to Chiari II malformation occurred in 18 patients. The masseter reflex was more frequently abnormal in the symptomatic than asymptomatic patients (P = 0.02). Although the blink reflex was similarly affected in the two groups of patients (P > 0.1), it was very sensitive, being abnormal in 83% of symptomatic and 65% of asymptomatic patients. Concomitant abnormality of masseter reflex and the late contralateral blink reflex component (R2c) was almost exclusively found in symptomatic patients…
Natural course of Fabry disease: changing pattern of causes of death in FOS - Fabry Outcome Survey
2009
Background: Fabry disease is a rare X-linked lysosomal storage disorder characterised by severe multisystemic involvement that leads to major organ failure and premature death in affected men and women. Over the past 7 years, the Fabry Outcome Survey (FOS) has collected data on the natural history of Fabry disease, and the long-term efficacy and safety of enzyme-replacement therapy. This paper provides an update on the first analysis of FOS data. Design: Baseline data on clinical manifestations and causes of death in a cohort of 1453 patients (699 male, 754 female) from 19 countries worldwide were analysed. Causes of death of affected relatives were analysed separately. Results: The most fr…
Prognosis Biomarkers of Severe Sepsis and Septic Shock by 1H NMR Urine Metabolomics in the Intensive Care Unit.
2015
Early diagnosis and patient stratification may improve sepsis outcome by a timely start of the proper specific treatment. We aimed to identify metabolomic biomarkers of sepsis in urine by (1)H-NMR spectroscopy to assess the severity and to predict outcomes. Urine samples were collected from 64 patients with severe sepsis or septic shock in the ICU for a (1)H NMR spectra acquisition. A supervised analysis was performed on the processed spectra, and a predictive model for prognosis (30-days mortality/survival) of sepsis was constructed using partial least-squares discriminant analysis (PLS-DA). In addition, we compared the prediction power of metabolomics data respect the Sequential Organ Fai…
