Oral mucosal peeling related to dentifrices and mouthwashes: A systematic review

2018

Background The aim of this systematic review was to summarise the clinical information available about oral mucosal peeling (OMP) and to explore its aetiopathogenic association with dentifrices and mouthwashes. Material and Methods PICOS outline: Population: subjects diagnosed clinically and/or pathologically. Intervention: exposition to oral hygiene products. Comparisons: patients using products at different concentrations. Outcomes: clinicopathological outcomes (primary) and oral epithelial desquamation (secondary) after use. Study design: any. Exclusion criteria: reports on secondary or unpublished data, in vitro studies. Data were independently extracted by two reviewers. Results Fiftee…

An Exploratory Look at Bicuspid Aortic Valve (Bav) Aortopathy: Focus on Molecular and Cellular Mechanisms

2019

Bicuspid aortic valve (BAV) is the most common congenital heart malformation. BAV patients are at increased risk for aortic valve disease (stenosis/regurgitation), infective endocarditis, thrombi formation and, in particular, aortic dilatation, aneurysm and dissection. This review aims at exploring the possible interplay among genetics, extracellular matrix remodeling, abnormal signaling pathways, oxidative stress and inflammation in contributing to BAV-associated aortopathy (BAV-A-A). Novel circulating biomarkers have been proposed as diagnostic tools able to improve risk stratification in BAV-A-A. However, to date, the precise molecular and cellular mechanisms that lead to BAV-A-A remain …

Gingival recession: prevalence and risk indicators among young greek adults

2014

Objectives: The aim of the current research was to assess the prevalence of gingival recession and to investigate possible associations among this condition, periodontal and epidemiological variables in a sample of young Greek adults in a general dental practice. Material and Methods: A total of 1,430 young adults was examined clinically and interviewed regarding several periodontal and epidemiological variables. Collected data included demographic variables, oral hygiene habits and smoking status. Clinical examination included the recording of dental plaque, supragingival calculus presence, gingival status and buccal gingival recession. Multivariate logistic regression analysis model was p…

Prognostic impact of hypertension and carotid lesions in a five years follow-up

Softwareassistierte CT-Nachverarbeitung am Beispiel der Karotiden

2004

Ziel der Arbeit: Es sollte ein Softwareassistent fur die automatisierte Auswertung von CT-Angiographien entwickelt werden, der die Visualisierung des Gefaslumens und eine quantitative Auswertung von Stenosen ermoglicht. Die klinische Erprobung erfolgt am Beispiel der A. carotis. Methodik: Bei insgesamt zwolf Patienten mit Verdacht auf eine hohergradige Stenose der Karotiden wurde eine CT-Angiographie (CTA) mit einem Mehrzeilen-CT durchgefuhrt. Diese Daten wurden mit dem neuen Softwareassistenten analysiert und ausgewertet. Die Ergebnisse verglich man mit der digitalen Subtraktionsangiographie (DSA). Ergebnisse: Die Nachverarbeitungszeit der CT-Datensatze mit Hilfe des Softwareassistenten li…

Intravascular Ultrasound-based Imaging Modalities for Tissue Characterisation

2014

Atherosclerosis is the leading cause of cardiovascular mortality and morbidity in the developed world. Intravascular ultrasound (IVUS) is a widely used imaging modality providing complementary diagnostic information to angiography regarding the vessel wall of the coronary arteries. IVUS has been used for assessment of ambiguous angiographic lesions, evaluation of new interventional devices and in atherosclerosis progression-regression trials. However, the standard gray-scale IVUS has limited value for the accurate identification of specific plaque components. This limitation has been partially over- come by introduction of new IVUS-based imaging methods such as: virtual histology IVUS, iMAP…

Coronary plaque imaging with multislice computed tomography: technique and clinical applications.

2006

The composition of an atherosclerotic lesion, rather than solely the degree of stenosis, is considered to be an important determinant of acute coronary events. Whereas until recently only invasive techniques have been able to provide clues about plaque composition with consistent reproducibility, several recent studies have revealed the potential of multislice computed tomography (MSCT) for noninvasive plaque imaging. Coronary MSCT has the potential to detect coronary plaques and to characterize their composition based on the X-ray attenuating features of each structure. MSCT may also reveal the total plaque burden (calcified and noncalcified components) for individual patients with coronar…

Effect of probiotics as a complement to non-surgical periodontal therapy in chronic periodontitis : a systematic review

2020

Background To improve the results of the classic periodontal treatment, probiotics have been suggested recently to decrease the number of bacteria and the expression of mediators of inflammation. This systematic review aimed to assess the literature for the effectiveness of different probiotic strains as adjuvants to non-surgical periodontal therapy. Material and Methods The electronic database of MEDLINE (via Pubmed) was searched up to December 2017 for randomised clinical trials in English comparing non-surgical periodontal treatment and probiotics versus periodontal treatment and placebo. The primary outcome investigated was reduction in pocket probing depth. Secondary outcomes were blee…

Shockwave intravascular lithoplasty for the treatment of calcified carotid artery stenosis: A very early single-center experience

2020

Endovascular treatment of calcified carotid disease represents one of the main challenges for the interventionalists. Plaque calcium load is one of the most important factors affecting the risk of procedural complications. A new tool called Shockwave intravascular lithotripsy (S-IVL; Shockwave Medical, Inc.) has been recently approved for the treatment of heavily calcified coronary and lower limb arteries but minimal data exist about the treatment of carotid arteries. We report our early experience of carotid stenting using S-IVL. We report two cases of symptomatic patients with severely calcified carotid artery diseases who were turned down for vascular surgeries. The first case was succes…

Pyogenic granuloma in relation to dental implants: Clinical and histopathological findings

2015

Background: The occurrence of pyogenic granuloma in association to dental implants is rare and only five cases have been reported in the literature. Material and Methods: Patients charts were analyzed to select patients who had been diagnosed for pyogenic granuloma and its association with dental implants had been evaluated. The clinical status of the dental implants and the prosthesis had also been assessed. Results: Clinical and histopathological diagnosis of pyogenic granuloma had been reached for soft mass growth in association with dental implants in 10 patients. Histological analysis of all samples was performed to obtain a firm diagnosis of finding against pyogenic granuloma lesions.…
