Scoring systems for Oral Lichen Planus used by differently experienced raters
2017
BACKGROUND: Scoring systems have been widely used to evaluate the severity and activity of oral lichen planus (OLP). The aim of the present study was to compare two existing (one modified) scoring systems in the evaluation of OLP severity and correlation with pain. Three differently experienced raters were involved. MATERIALS AND METHODS: Consecutive patients with OLP were assessed for pain using the Visual Analogue Scale and examined at 10 intraoral sites before starting (T0) and three weeks after (T1) steroid therapy (Clobetasol). Three differently experienced raters evaluated photographs using two scoring systems designated White-Erosive-Atrophic (WEA) modified from an older WEA system (…
Reproducibility and validity of the physical activity scale for the elderly (PASE) questionnaire in patients after total hip arthroplasty.
2014
Background The assessment of physical activity is of concern in patients after total hip arthroplasty (THA). However, so far, no questionnaire has demonstrated adequate reproducibility and validity for assessing physical activity in these patients. Objective The aim of this study was to evaluate the reproducibility and validity of the Physical Activity Scale for the Elderly (PASE) questionnaire in patients after THA. Design This was a measurement study. Methods Fifty patients who had undergone THA (25 women, 25 men), with an average age of 68 years, were evaluated. Of these patients, 25 were assessed between 2 and 7 months after surgery (THAearly), and another 25 were assessed between 7 an…
Acute Kidney Injury After Percutaneous Edge-to-Edge Mitral Repair.
2020
BACKGROUND In catheter-based procedures, acute kidney injury (AKI) is a frequent, serious complication ranging from 10% to 30%. In MitraClip (Abbott Vascular, Santa Clara, California), a usually contrast-free procedure, there is scarce data about its real incidence and impact. OBJECTIVES This study aimed to evaluate incidence, predictive factors, and midterm outcomes of AKI in patients with significant mitral regurgitation (MR) undergoing transcatheter valve repair with MitraClip. METHODS A total of 721 patients undergoing MitraClip were included. AKI was defined as an absolute or a relative increase in serum creatinine of >0.3 mg/dl or >= 50%, respectively, or the need for hemodialysis dur…
Opposite role played by GABAA and GABAB receptors in the modulation of peristaltic activity in mouse distal colon.
2014
We investigated the role of GABA on intestinal motility using as model the murine distal colon. Effects induced by GABA receptors recruitment were examined in whole colonic segments and isolated circular muscle preparations to analyze their influence on peristaltic reflex and on spontaneous and neurally-evoked contractions. Using a modified Trendelenburg set-up, rhythmic peristaltic contractions were evoked by gradual distension of the colonic segments. Spontaneous and neurally-evoked mechanical activity of circular muscle strips were recorded in vitro as changes in isometric tension. GABA, at low concentrations (10-50 µM), potentiated peristaltic activity and the neural cholinergic contrac…
Hippocampal dopamine receptors modulate the motor activation and the increase in dopamine levels in the rat nucleus accumbens evoked by chemical stim…
2005
A number of studies have shown that chemical stimulation (using N-methyl-D-aspartate (NMDA) infusions) or electrical stimulation of the ventral hippocampus (VH) elicits locomotor activation and sustained increases in nucleus accumbens (NAc) dopamine (DA) levels in rodents. How DA neurotransmission in NAc is involved in these effects has also been well established. However, the modulatory role of the DA receptors located in VH is not yet fully understood. The purpose of this study was to characterize the role played by VH D1 and D2 subtype receptors in both the locomotor activation and NAc DA increases induced by NMDA stimulation of the VH. This was assessed by studying how retrodialysis app…
Hippocampal dopamine receptors modulate cFos expression in the rat nucleus accumbens evoked by chemical stimulation of the ventral hippocampus
2005
Recently, we have shown that D1 and D2 receptors in the ventral hippocampus (VH) modulate both the locomotor activation and the increase in dopamine (DA) levels in the rat nucleus accumbens (NAc) induced by NMDA stimulation of the VH. In the present study we analyze the possible role of VH D1 and D2 receptors in the modulation of the cFos expression in NAc (core and shell subregions) and in dorsal striatum. This was assessed by immunohistochemical analysis of cFos expression in the rat brains after retro-dialysis application of NMDA (50mM, 10 min) into VH, in absence and in presence of either the D1/D5 receptor antagonist SCH 23390 (100 and 250 microM, 60 min) or the D2 receptor antagonist …
GABAergic inhibition of nitric oxide-mediated relaxation of guinea-pig ileum
1999
The effects of GABA receptor agonists were investigated on guinea-pig isolated ileum longitudinal muscle with intact myenteric plexus. Electrical field stimulation (1 Hz, 10 s) of the histamine (1 microM)-precontracted preparation caused a contraction followed by a relaxation. Relaxations were inhibited by L-N(G)-nitroarginine (L-NA; EC50 3 microM) in a concentration-dependent manner. The inhibitory action of 10 microM L-NA was blocked by 10 microM L-arginine but not by D-arginine, which indicates that the relaxation was largely mediated by endogenous nitric oxide (NO). Tetrodotoxin (1 microM) reduced the relaxation only by about 50%. GABA and the GABA(B) agonist, baclofen, inhibited the fi…
Sicilian DES Registry: prospective in-hospital and 9-month clinical and angiographic follow-up in selected high restenosis risk patients.
2008
OBJECTIVE: This is a multicentre, open label, prospective non-randomized registry, with 9-month angiographic follow-up, conducted to evaluate the safety and effectiveness of drug-eluting stents (DES) when used in high restenosis risk patients from the real world. METHODS: From June 2004 to February 2005, a total of 1622 consecutive patients were enrolled to the Sicilian DES Registry, according to specific inclusion criteria. Both paclitaxel-eluting and sirolimus-eluting stents were used. The analysis was performed on 1472 patients because 150 patients were excluded from the study. The primary endpoint was to evaluate the rate of major adverse cardiac events (MACE) within 9 months after DES …
Long-term clinical outcomes after drug-eluting stent implantation in unprotected left main coronary artery disease.
2009
Objective: To investigate long-term outcomes of unprotected left main coronary artery (ULMCA) disease treatment using drug-eluting stents (DES). Background: In several studies, DES implantation in ULMCA appeared safe and effective at mid-term; however, to date, there is limited long-term data. Methods: All consecutive patients undergoing sirolimus- or paclitaxel-eluting stent implantation in ULMCA disease at a single institution were evaluated. The primary endpoint was long-term major adverse cardiac events (MACE) defined as cardiac death, nonfatal myocardial infarction, or target lesion revascularization (TLR). Stent thrombosis (ST), according to Academic Research Consortium definitions, w…
Immediate effect of the MitraClip procedure on mitral ring geometry in primary and secondary mitral regurgitation.
2013
Percutaneous treatment of mitral regurgitation (MR) has been shown to reduce MR severity and improve functional outcomes. Surgical treatment of MR usually includes mitral annulus reduction. The influence of the MitraClip w on annulus geometry is not clear. We wanted to investigate whether the procedure itself reduces annulus diameter and if there may be differences between secondary or functional (SMR) and primary (PMR) MR. Methods and results We retrospectively assessed 3D echocardiography (3D-TEE) data of 55 patients acquired during the procedure shortly before and after clip placement for changes in annulus diameter and area. Measurements were done with QLAB software. Patients were categ…
