LATE-BREAKING ABSTRACT: Comparative studies on bronchuswall-thickness by histologic and computed tomographic measurements of porcine lungs
2015
Aims: Histologic slides are commonly used as template in the evaluation and development of medical imaging methods.Diseases like Asthma and COPD show characteristic changes in airway morphology and airway measurement by computed tomography is a promising diagnostic approach.However,shrinkage caused by fixation and histological processing is known in lung tissue.In this study,the thickness of bronchus walls in paraffin and frozen sections as well as in CT and MicroCT were compared. Methods: Airway measurements of swine lungs were performed after freezing in ventilated condition in liquid nitrogen by measuring the wall thickness of 7 bronchi via CT and MicroCT as well as in frozen and paraffi…
Die sonographische Gallenblasenwandverdickung und ihre diagnostische Bedeutung bei intensivpflichtigen Patienten
2008
In a prospective study including 398 intensive-care patients, we analysed the ultrasonographic relevance of a gallbladder wall thickening. In 24 of 398 (6%) cases a wall thickening was found that could be differentiated into two types of walls. In 20.8% (5/24) the gallbladder wall thickening was an expression of an acute cholecystitis. In further differential diagnosis of a gallbladder wall thickening pathological states with hypoalbuminaemia occupy the prime position. The pathological mechanism has not yet been completely clarified. Hypoalbuminaemia without inflammatory alterations of the organ was found in 37.5% of the cases with gallbladder wall thickening. In 41.6% of the patients the w…
Laryngopharyngeal reflux as a potential cause of persistent local neck symptoms after total thyroidectomy
2020
Abstract Purpose Local neck symptoms (LNS) may be related to goiter, but are also reported by patients suffering from laryngeal–pharyngeal reflux (LPR). The aim of this study was to investigate whether LPR could play a role in the persistence of some LNS after total thyroidectomy (TT). Methods A consecutive case series of 160 patients with multinodular goiter (MNG) candidate for TT were included in this study. Each patient was closely studied for both the thyroid pathology and reflux disease before and 6 months after surgery to assess the persistence of LNS after surgery. Results Only throat discomfort showed a significant improvement (p = 0.031) after surgery. On the other hand, swallowin…
Horizontal and Vertical Reconstruction of the Severely Resorbed Maxillary Jaw Using Subantral Augmentation and a Novel Tenting Technique with Bone fr…
2013
Aim The aim of this study was to evaluate the effect of using the lateral wall bone in sinus lifting two-dimensional reconstruction on bone augmentation.Patients and Methods Ten patients affected by class V or VI maxillary atrophy with less than 3 mm of residual horizontal ridge were selected. Using a piezo-ultrasonic surgery tip bony lateral wall was cut. To expose native bone to the bone graft, multiple perforations, made through the cortical plate of the recipient site with a round bur. Once the bony buccal wall was adjusted it was fixed away from the ridge with two 1.5 x 13 mm bone fixation screws. Deficiencies created between the bony buccal wall and the ridge was filled with a mineral…
Biologic Response of Inguinal Hernia Prosthetics: A Comparative Study of Conventional Static Meshes Versus 3D Dynamic Implants
2015
Despite improvements in prosthetics and surgi- cal techniques, the rate of complications following inguinal hernia repair remains high. Among these, discomfort and chronic pain have become a source of increasing concern among surgeons. Poor quality of tissue ingrowth, such as thin scar plates or shrinking scars—typical results with con- ventional static implants and plugs—may contribute to these adverse events. Recently, a new type of 3D dynami- cally responsive implant was introduced to the market. This device, designed to be placed fixation-free, seems to induce ingrowth of viable and structured tissue instead of regressive fibrotic scarring. To elucidate the differences in biologic respo…
THU0406 ULTRASONOGRAPHIC INVOLVEMENT OF THE ANTERIOR CHEST WALL IN SPONDYLOARTHRITIS, A FIVE YEARS FOLLOW UP STUDY
2019
Background Spondyloarthrits is characterized by inflammatory back pain. Anterior chest wall pain is common and a previous study reported a prevalence a 37% of ultrasonographic lesions of this anatomical region [1]. Objectives The objective of this study is to evaluate, in patient with Spondyloarthritis, the prevalence of ACW ultrasonographic lesions after a follow up of 5 years and to identify factors associated with the development of new lesions. Methods This a monocentric and prospective study including patients with Spondyloarthritis meeting the ASAS 2009 criteria. Patients were followed during five years. ultrasound B mode and power Doppler examination of the two sternoclavicular joint…
Rheumatoid arthritis affects left ventricular mass: Systematic review and meta-analysis.
2015
Abstract Background Cardiovascular disease represents one of the most important extra-articular causes of morbidity and mortality in patients with rheumatoid arthritis (RA). Evidences showed that several cardiac structures can be affected during the course of the disease as well as abnormalities of left ventricular diastolic filling. Contrasting data are available about left ventricular mass (LVM) involvement in patients asymptomatic for cardiovascular disease. The purpose of this systematic review and meta-analysis is to summarize the effects of RA on LVM in rheumatoid arthritis patients without cardiovascular disease. Methods A systematic research of the current case–control studies was c…
Effect of the Alterations in Contractility and Morphology Produced by Atrial Fibrillation on the Thrombosis Potential of the Left Atrial Appendage
2021
Atrial fibrillation (AF) is a common arrhythmia mainly affecting the elderly population, which can lead to serious complications such as stroke, ischaemic attack and vascular dementia. These problems are caused by thrombi which mostly originate in the left atrial appendage (LAA), a small muscular sac protruding from left atrium. The abnormal heart rhythm associated with AF results in alterations in the heart muscle contractions and in some reshaping of the cardiac chambers. This study aims to verify if and how these physiological changes can establish hemodynamic conditions in the LAA promoting thrombus formation, by means of computational fluid dynamic (CFD) analyses. In particular, sinus …
Eight-point compass rose underlay technique in 72 consecutive elderly patients with large incisional hernia
2011
Summary Background Repair of incisional hernia (IH) in the elderly is a challenge for the surgeon. Primary closure is preferable but is not always possible because of high recurrence rates of IH repaired without a prosthesis and/or possible respiratory and cardiovascular complications due to extreme tension of the margins. We report our experience with underlay mesh placement in elderly patients with large IH. Methods A total of 72 patients from January 2003 to December 2009 underwent IH repair involving placement of an intraperitoneal Gore® DualMesh® prosthesis. The prosthesis was first anchored at eight points in a compass rose pattern using a Gore® suture passer and then firmly secured t…
Takotsubo cardiomyopathy features at cardiac magnetic resonance
2012
Abstract Diagnosis of Takotsubo cardiomyopathy is based on clinical symptoms, electrocardiographic changes, absence of angiographic significant coronary lesions and presence of suggestive wall motion abnormalities. CardioMRI is an useful complementary tool especially to role out the diagnosis of myocarditis and of myocardial infarction with angiographically normal coronary artery and to document complications of the disease.
