1997

Die neueren QCA-Systeme weisen bei In-vitro-Messungen eine vergleichbare Reproduzierbarkeit und Genauigkeit der Mesergebnisse auf. Wir untersuchten, welchen Einflus die Morphologie von Koronararterienstenosen und die Bildqualitat auf die Mesergebnisse von drei fuhrenden QCA-Systemen (AWOS, Cardio und CMS) hat. Hierzu wahlten wir 57 Stenosen aus, die eine klinisch reprasentative Verteilung bezuglich des Stenosegrades, verschiedener Lasionscharakteristika und der Bildqualitat aufwiesen. Prozedurale Fehlerquellen wurden, soweit moglich, eliminiert. Drei Untersucher fuhrten je Stenose funf Messungen mit jedem der drei Systeme durch. Bei drei Stenosen war eine Auswertung nicht moglich.

VATER/VACTERL association: clinical variability and expanding phenotype including laryngeal stenosis.

1992

Vertebral abnormalities and anorectal and tracheoesophageal defects are the main manifestations in the VATER/VACTERL association. Radial defects vary from radial aplasia to thumb duplication. Heart and renal defects are reported with lower frequency. Additional malformations, such as the laryngeal stenosis described in the present patient, may expand the phenotype of the association. The wide spectrum of congenital abnormalities confirms the high clinical variability of VATER/VACTERL association which seems to be due to a disruption of blastogenesis. © 1992 Wiley-Liss, Inc.

The Association of H1N1 Pandemic Influenza with Congenital Anomaly Prevalence in Europe

2015

BACKGROUND: In the context of the European Surveillance of Congenital Anomalies (EUROCAT) surveillance response to the 2009 influenza pandemic, we sought to establish whether there was a detectable increase of congenital anomaly prevalence among pregnancies exposed to influenza seasons in general, and whether any increase was greater during the 2009 pandemic than during other seasons.METHODS: We performed an ecologic time series analysis based on 26,967 pregnancies with nonchromosomal congenital anomaly conceived from January 2007 to March 2011, reported by 15 EUROCAT registries. Analysis was performed for EUROCAT-defined anomaly subgroups, divided by whether there was a prior hypothesis of…

High Rate of Studies with Level 1 and 2 Evidence among the 100 Most Cited Articles in Lumbar Spinal Stenosis.

2021

Abstract Background To date, no study has used bibliometric analysis to review the most influential articles in lumbar spinal stenosis. The objective of this study was to identify and analyze the characteristics and the level of evidence of the 100 most cited articles on lumbar spinal stenosis Methods The Thomson Reuters Web of Science was accessed to find the 100 most cited articles on lumbar spinal stenosis. For each article, we recorded the number and density of citations, authors, country, journals and years, department, level of evidence, type of study, and if it was part of any multicenter studies. Results Until January 2017, the 100 most cited articles accumulated 11,136 citations (a…

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

Surgical management of benign tracheal stenosis.

2014

Abstract This chapter provides a step-by-step explanation of the indications, basic technique and pitfalls of tracheal surgery for cases of benign tracheal stenosis. Approach, trachea dissection and end-to-end anastomosis in tracheal surgery is described in detail. An algorithm for laryngotracheal technique selection according to different criteria (stenosis location, vocal cords status and tracheal mucosa and/or cartilaginous larynx involvement) is also depicted. Finally, a review of the most important reported series in tracheal surgery is presented.

Left bundle branch block and myocardial infarction, a diagnosis not always easy: Our experience and review of literature

2012

The occurrence of left bundle branch block (LBBB) is quite common in clinical practice. The changes in cardiac repolarization, caused by this disorder of electric conduction, may mask the presence of an acute myocardial infarction (AMI), delaying the diagnostic-therapeutic iter, with an important impact on prognosis. We describe the case of a woman of 59 years with LBBB, came to our observation for a constrictive chest pain associated with dyspnea. The diagnostic workup for suspected acute coronary syndrome (ACS), initially conducted only on the analysis of the electrocardiogram (negative TnI at entry), showed the presence of coronary arteries free of stenosis. However, the diagnostic confi…

Local Application of Leptin Antagonist Attenuates Angiotensin II–Induced Ascending Aortic Aneurysm and Cardiac Remodeling

2016

Background Ascending thoracic aortic aneurysm ( ATAA ) is driven by angiotensin II (Ang II ) and contributes to the development of left ventricular ( LV ) remodeling through aortoventricular coupling. We previously showed that locally available leptin augments Ang II ‐induced abdominal aortic aneurysms in apolipoprotein E–deficient mice. We hypothesized that locally synthesized leptin mediates Ang II ‐induced ATAA . Methods and Results Following demonstration of leptin synthesis in samples of human ATAA associated with different etiologies, we modeled in situ leptin expression in apolipoprotein E–deficient mice by applying exogenous leptin on the surface of the ascending aorta. This treatm…
