Die Positronenemissionstomographie zur pr�operativen Lymphknotendiagnostik bei �sophaguskarzinom

2003

Vorraussetzung fur Indikation und Wahl des geeigneten operativen Verfahrens bei Patienten mit Osophaguskarzinom ist ein genaues praoperatives Staging. Ziel der prospektiven Studie war es, zu klaren, ob eine Positronenemissionstomographie mit 18F-Fluoro-Deoxyglukose (FDG-PET) die Genauigkeit des praoperativen Lymphknotendiagnostik gegenuber der Computertomographie (CT) erhoht und die Wahl des operativen Zugangs zur Osophagusresektion beeinflusst. 58 Patienten, 46 Manner und 12 Frauen (Alter 61 Jahre im Mittel), erhielten bei histologisch gesichertem Osophaguskarzinom im Rahmen des Stagings ein FDG-PET von Hals, Thorax und Abdomen sowie ein CT von Thorax und Abdomen.

TEVAR and periscope graft technique to treatment of huge aneurysm of aortic isthmus: Case report

2021

Introduction Thoracic endovascular aortic repair (TEVAR) has revolutionized the treatment of thoracic aortic aneurysms. Innovative techniques as chimney and periscope grafts can improve the outcomes of procedure. Herein, we report a case in emergency of huge Thoracic aortic aneurism. Presentation of case An 86-year-old male with hypertension, diabetes mellitus, was referred to our hospital for chest pain. CT-angiography showed a huge aneurysm of aortic isthmus with signs of rupture. The patient was considered unfit for open surgery and an endovascular approach was chosen. This patient underwent endovascular repair with TEVAR, using the periscope graft technique to preserve patency in left s…

Official Statement of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) on Electronic Cigarettes and IQOS®.

2019

The use of novel tobacco products, particularly the electronic cigarette (EC) and partial tobacco combustion devices (HnB systems: Heat not Burn), has increased exponentially, particularly among adolescents and young people. The health authorities and scientific societies have shown concern about issues surrounding safety and effectiveness (as a method of smoking cessation). A study of the available scientific evidence has concluded that the safety of the vapor or fumes inhaled by the users of these devices cannot be guaranteed. Contradictory results from various clinical trials and meta-analyses also mean that these devices cannot be recommended for their effectiveness in cessation, especi…

Endovascular management of a large aneurysm of the superior vena cava involving internal thoracic vein with remodeling technique

2016

International audience; We report a case describing endovascular treatment of a large aneurysm of the superior vena cava involving internal thoracic vein. The goal of this case report is to highlight the contributing role of embolization with remodeling technique in such an exceptional condition.

Correction to: Protective ventilation with high versus low positive end-expiratory pressure during one-lung ventilation for thoracic surgery (PROTHOR…

2019

Background Postoperative pulmonary complications (PPC) may result in longer duration of in-hospital stay and even mortality. Both thoracic surgery and intraoperative mechanical ventilation settings add considerably to the risk of PPC. It is unclear if one-lung ventilation (OLV) for thoracic surgery with a strategy of intraoperative high positive end-expiratory pressure (PEEP) and recruitment maneuvers (RM) reduces PPC, compared to low PEEP without RM. Methods PROTHOR is an international, multicenter, randomized, controlled, assessor-blinded, two-arm trial initiated by investigators of the PROtective VEntilation NETwork. In total, 2378 patients will be randomly assigned to one of two differe…

Light on the molecular and cellular mechanisms of bicuspid aortic valve to unveil phenotypic heterogeneity

2019

Research on bicuspid aortic valve disease (BAV) and related complications has grown in an exponential manner in the last decades. However, the current knowledge of the mechanisms underlying the development of this disease is still limited, since all clinical and surgical studies on BAV mainly focused their objects on its major vascular complications, such as ascending aortic aneurysms and dissection. It is now clear that a better understanding of the pivotal molecular and cellular pathophysiological aspects of bicuspid valve aortopathy, including natural history, phenotypic expression, histology, cellular mechanisms and pathways, is critical for improving its clinical management. This chang…

The campomelic syndrome: review, report of 17 cases, and follow-up on the currently 17-year-old boy first reported by Maroteaux et al in 1971.

1983

We report 17 cases of the campomelic syndrome (CS) and a follow-up of one of the original patients of Maroteaux et al who is now 17 years old. Our review is based on 97 patients, including our own. An infant with the CS presents at birth with spectacularly short and bowed femora and tibiae. The initial chest radiograph confirms the diagnosis by demonstrating extremely small bladeless scapulae and hypoplastic pedicles of many thoracic vertebrae. Ossification of the sternal segments, pubis, talus, and knee epiphyses is also retarded. Usually the hips are dislocated and talipes equinovarus deformities are present. There is a small chondrocranium and a disproportionately large neurocranium. The…

Enhanced prolylhydroxylase activity in the posterior annulus fibrosus of canine intervertebral discs following long-term running exercise

2010

The effect of long-term excercise on the intervertebral disc collagen concentration (hydroxyproline), collagen-synthesizing enzymes (prolyl-4-hydroxylase, PH, and galactosyl-hydroxylysyl glucosyltransferase, GGT) and hydroxypyridinium crosslinks was studied in ten female beagle dogs. The dogs were run on a treadmill for 1 year starting at the age of 15 weeks. The daily running distance was gradually increased to 40km, which distance the dogs ran for the final 15 weeks. Ten untrained dogs from the same breeding colony served as controls. The nucleus pulposus and anterior and posterior halves of the annulus fibrosus of C2-3, T10-12, L4-5 disc segments were analysed. Crosslinks were measured f…
