Alveolar graft in the cleft lip and palate patient: Review of 104 cases
2014
Introduction: Alveolar bone grafting is a vital part of the rehabilitation of cleft patients. The factors that have been most frequently associated with the success of the graft are the age at grafting and the pre-grafting orthodontic treatment. Objectives: 1) Describe the cases of alveolar bone grafts performed at the Maxilofacial Unit of Hospital Sant Joan de Déu, Barcelona (HSJD); and 2) Analyze the success/failure of alveolar grafts and related variables. Material and Methods: Descriptive retrospective study using a sample of 104 patients who underwent a secondary alveolar graft at the Craniofacial Unit of HSJD between 1998 and 2012. The graft was done by the same surgeon in all patient…
Five cases of de novo inflammatory bowel disease after orthotopic liver transplantation.
2006
Immunosuppression is currently the treatment of choice for severe inflammatory bowel disease (IBD). Thus, it was anticipated that the course of preexisting IBD should improve after orthotopic liver transplantation (OLT). Despite sufficient allograft immunosuppressive therapy, however, exacerbation of IBD or the development of de novo IBD after OLT were described in some cases, primarily in patients transplanted for end-stage primary sclerosing cholangitis (PSC). In addition, the development of de novo IBD in patients undergoing OLT for indications other than PSC was described. Evaluating our collective of 314 liver transplanted patients we found five patients transplanted for various indica…
Acute social defeat stress increases the conditioned rewarding effects of cocaine in adult but not in adolescent mice.
2015
Stressful experiences modify activity in areas of the brain involved in the rewarding effects of psychostimulants. In the present study we evaluated the influence of acute social defeat (ASD) on the conditioned rewarding effects of cocaine in adolescent (PND 29-32) and adult (PND 50-53) male mice in the conditioned place preference (CPP) paradigm. Experimental mice were exposed to social defeat in an agonistic encounter before each session of conditioning with 1mg/kg or 25mg/kg of cocaine. The effects of social defeat on corticosterone levels were also evaluated. Adult mice exposed to ASD showed an increase in the conditioned reinforcing effects of cocaine. Only these mice developed cocaine…
The Novel μ-Opioid Receptor Antagonist GSK1521498 Decreases Both Alcohol Seeking and Drinking: Evidence from a New Preclinical Model of Alcohol Seeki…
2015
Distinct environmental and conditioned stimuli influencing ethanol-associated appetitive and consummatory behaviors may jointly contribute to alcohol addiction. To develop an effective translational animal model that illuminates this interaction, daily seeking responses, maintained by alcohol-associated conditioned stimuli (CSs), need to be dissociated from alcohol drinking behavior. For this, we established a procedure whereby alcohol seeking maintained by alcohol-associated CSs is followed by a period during which rats have the opportunity to drink alcohol. This cue-controlled alcohol-seeking procedure was used to compare the effects of naltrexone and GSK1521498, a novel selective μ-opioi…
Contrast-induced Nephropathy after Percutaneous Coronary Intervention in Simple Lesions: Risk Factors and Incidence are Affected by the Definition Ut…
2011
Aim To compare the incidence, and risk factors, in-hospital and at the 18-month prognosis of contrast-induced nephropathy (CIN) according to the definition utilized: as an increase in serum creatinine (Scr) ≥0.5 mg/dL (CIN 1) or as an increase in Scr ≥25% above baseline values (CIN 2). Methods and Results We prospectively evaluated CIN according to two different definitions in 150 patients who underwent percutaneous coronary intervention (PCI) in simple lesions employing a low-medium dose of contrast media. Incidence of CIN was higher using the CIN 2 definition than CIN 1 (9.3% vs. 4%; p=0.0133). Patients with CIN 1 had a higher incidence of chronic kidney disease (CKD) (66.7% vs. 13.9%; p=…
Changes inα-tocopherol and retinol levels during cardiopulmonary bypass correlate with maximal arterial partial pressure of oxygen
2007
Cardiopulmonary bypass (CPB) is associated with oxidative stress. This study examined antioxidant levels in adults undergoing CPB surgery and their correlation with clinical variables. Arterial blood samples were obtained from 27 patients undergoing CPB. The time-course variation of vitamin C (spectrofluorimetry), alpha-tocopherol and retinol (HPLC) levels were determined. Plasma vitamin C rose initially but gradually decayed during reperfusion until 60% reduction of baseline values post-surgery. alpha-Tocopherol and retinol were reduced along CPB with post-operative values approximately 25% lower than baseline. No significant changes were found for selenium and glutathione peroxidase. PaO(…
Blood Infusion and the Risk of Haemorrhage in Patients Undergoing Cardiac Surgery with Extracorporeal Circulation.
2016
Purpose: Patients undergoing cardiac surgery with extracorporeal circulation (ECC) frequently present haemorrhages as a complication associated with high morbidity and mortality. One of the factors that influences this risk is the volume of blood infused during surgery. The objective of this study was to determine the optimal volume of autologous blood that can be processed during cardiac surgery with ECC. We also determined the number of salvaged red blood cells to be reinfused into the patient in order to minimize the risk of haemorrhage in the postoperative period. Methods: This was an observational retrospective cross-sectional study performed in 162 ECC cardiac surgery patients. Data r…
Prenatal cocaine alters later responses to morphine in adult male mice.
2006
Mice prenatally exposed to cocaine (25 mg/kg), physiological saline or non-treated during the last 6 days of pregnancy were evaluated as adults for the rewarding properties of 2 mg/kg of morphine, using the conditioned place preference (CPP) procedure. Likewise, isolated animals underwent a social interaction test with conspecifics after receiving the same morphine dose. Unlike control or animals pre-treated with saline, subjects prenatally treated with cocaine did not develop CPP with this dose of morphine. Only cocaine-exposed animals showed increased threat, avoidance and fleeing during the social encounter. No differences in motor effects of morphine were observed. Analysis of monoamine…
A Sequential Algorithm Combining ADAPT and Liver Stiffness Can Stage Metabolic-Associated Fatty Liver Disease in Hospital-Based and Primary Care Pati…
2020
INTRODUCTION Metabolic-associated fatty liver disease is common, with fibrosis the major determinant of adverse outcomes. Population-based screening tools with high diagnostic accuracy for the staging of fibrosis are lacking. METHODS Three independent cohorts, 2 with both liver biopsy and liver stiffness measurements (LSMs, n = 254 and 65) and a population sample (n = 713), were studied. The performance of a recently developed noninvasive algorithm (ADAPT [age, diabetes, PRO-C3 and platelets panel]) as well as aspartate aminotransferase-to-platelet ratio index, fibrosis-4, nonalcoholic fatty liver disease fibrosis score, and LSM was used to stage patients for significant (≥F2) and advanced …
Liver Transplantation for Hepatocellular Carcinoma After Yttrium Therapy: A Case Report
2008
Yttrium-90 microspheres constitute one of the most recent treatment options for hepatocellular carcinoma (HCC) in the setting of cirrhosis. As such, their spectrum of indication is not yet fully established. Herein, we have reported the case of a patient with HCC beyond the listing criteria for liver transplantation (OLT) who was treated preoperatively with selective transarterial chemoembolization and yttrium-90 microspheres. He was subsequently transplanted with a liver from an 81-year-old donor allocated through Eurotransplant as a "rescue offer." The posttransplant course was uneventful. Pathologic examination revealed a multifocal, well-differentiated pT2 tumor with no vascular invasio…
