    Objective: Solitary fibrous tumours of the pleura (SFTP) are rare and can histologically be differentiated into benign and malignant forms. The aim of this study is to present new cases, and discuss up-to-date preoperative examinations, the role of video-assisted thoracic surgery and long-term outcome. Methods: Between 1993 and 2006, 27 SFTPs were diagnosed (14 females, mean age±SD, 62.3±9.6 years) at our institution. Medical records were reviewed, and follow-up was obtained by repeated examinations or contact with general practitioners. Results: SFTPs were associated with symptoms in 63% of all cases. In the six patients in which positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) was performed preoperatively, malignant lesions were all found to be positive. Complete resection was achieved by video-assisted thoracic surgery in 15 and anterolateral thoracotomy in 12 patients. Mean hospital stay was shorter for patients operated by video-assisted thoracic surgery compared to thoracotomy, 4.5 (range 3-6) versus 7.5 (range 4-25) days, respectively (pâ‰Ș0.01). Histology revealed 17 benign and 10 malignant SFTP. Mean±SD tumour diameter of malignant SFTPs was larger than in benign forms, 11.9±7.1 versus 6.1±3.5cm, respectively (pâ‰Ș0.01). Tumour recurrence was recognised in four patients with malignant SFTPs at a median time interval after surgery of 38 (range 6-122) months, two late deaths occurred resulting from tumour recurrences. Conclusions: SFTPs can be treated minimally invasively by video-assisted thoracic surgery with short hospital stay. Large SFTPs with increased FDG-uptake have a high likelihood for malignancy. Long-term follow-up is mandatory in malignant SFTPs because of late recurrences associated with deat

    Thoracic aortic aneurysms (TAA) may be associated with complications such as rupture and dissection, which can lead to a fatal outcome. Increased central arterial stiffness has been proposed to be present in patients with TAA compared to unmatched controls. We aimed to assess whether wall properties in patients with TAA are also altered when compared to a matched control group. Applanation tonometry was performed in 74 adults with TAA and 74 sex, age, weight, height, and left ventricular ejection fraction matched controls. Subsequently analysis of the pulse wave was done using the SphygmoCor System. For comparing the two groups, AIx was adjusted to a heart rate of 75/min (AIx@75). 148 1-to-1 matched participants were included in the final model. There was no significant difference in the Alx@75 between the TAA group and the matched control group [mean (SD) of 24.7 (11.2) % and 22.8 (11.2) %, p = 0.240]. Adjusted for known cardiovascular risk factors, there was no association between TAA and AIx@75. Patients with TAA showed comparable arterial wall properties to cardiovascular risk factor matched controls. Since higher arterial stiffness is associated with TAA progression, it remains to be investigated if increased central arterial stiffness is a relevant factor of TAA emergence.

    Common carotid intima–media thickness (CIMT) is a commonly used marker for atherosclerosis and is often computed in carotid ultrasound images. An analysis of different computerized techniques for CIMT measurement and their clinical impacts on the same patient data set is lacking. Here we compared and assessed five computerized CIMT algorithms against three expert analysts’ manual measurements on a data set of 1088 patients from two centers. Inter- and intra-observer variability was assessed, and the computerized CIMT values were compared with those manually obtained. The CIMT measurements were used to assess the correlation with clinical parameters, cardiovascular event prediction through a generalized linear model and the Kaplan–Meier hazard ratio. CIMT measurements obtained with a skilled analyst's segmentation and the computerized segmentation were comparable in statistical analyses, suggesting they can be used interchangeably for CIMT quantification and clinical outcome investigation. To facilitate future studies, the entire data set used is made publicly available for the community at http://dx.doi.org/10.17632/fpv535fss7.1

This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License.Aims: Acute pulmonary disorders are known physical triggers of takotsubo syndrome (TTS). This study aimed to investigate prevalence of acute pulmonary triggers in patients with TTS and their impact on outcomes. Methods and results: Patients with TTS were enrolled from the International Takotsubo Registry and screened for triggering factors and comorbidities. Patients were categorized into three groups (acute pulmonary trigger, chronic lung disease, and no lung disease) to compare clinical characteristics and outcomes. Of the 1670 included patients with TTS, 123 (7%) were identified with an acute pulmonary trigger, and 194 (12%) had a known history of chronic lung disease. The incidence of cardiogenic shock was highest in patients with an acute pulmonary trigger compared with those with chronic lung disease or without lung disease (17% vs. 10% vs. 9%, P = 0.017). In-hospital mortality was also higher in patients with an acute pulmonary trigger than in the other two groups, although not significantly (5.7% vs. 1.5% vs. 4.2%, P = 0.13). Survival analysis demonstrated that patients with an acute pulmonary trigger had the worst long-term outcome (P = 0.002). The presence of an acute pulmonary trigger was independently associated with worse long-term mortality (hazard ratio 2.12, 95% confidence interval 1.33-3.38; P = 0.002). Conclusions: The present study demonstrates that TTS is related to acute pulmonary triggers in 7% of all TTS patients, which accounts for 21% of patients with physical triggers. The presence of acute pulmonary trigger is associated with a severe in-hospital course and a worse long-term outcome.C. T. has been supported by the H.H.

    Ist die COPD ein kardiovaskulÀrer Risikofaktor?

    Full text link
    Die chronisch obstruktive Lungenerkrankung (COPD) ist gekennzeichnet durch einen EntzĂŒndungsprozess, welcher eine Flusslimitation in den Atemwegen verursacht und meistens auf die Inhalation von Tabakrauch zurĂŒckzufĂŒhren ist. Die COPD ist weltweit die fĂŒnfthĂ€ufigste Todesursache und bis zu 50% der COPD-Patienten sterben an einem kardiovaskulĂ€ren Ereignis. In Kohortenstudien konnte eine unabhĂ€ngige Assoziation zwischen dem Grad der Atemflusslimitation und kardiovaskulĂ€ren Erkrankungen auch nach Korrektur fĂŒr klassische Risikofaktoren wie Rauchen und Cholesterinspiegel gezeigt werden. Verschiedene Mechanismen der GefĂ€ssschĂ€digung werden bei COPD postuliert. Hierzu zĂ€hlen die systemische EntzĂŒndung, Hypoxie, oxidativer Stress, Sympathikusaktivierung und VerĂ€nderungen der GefĂ€ss-Bindegewebsmatrix. Die Evidenz fĂŒr eine kausale Beziehung zwischen COPD und kardiovaskulĂ€rer Erkrankung fehlt jedoch weitgehend und es werden dringend Ergebnisse von kontrollierten Studien zu den postulierten Pathomechanismen benötigt. = Chronic obstructive pulmonary disease (COPD) is an inflammatory disease of the lungs mainly caused by smoking and characterized by chronic airflow limitation. COPD is the fifth leading cause of death worldwide and up to 50% of COPD patients die of a cardiovascular event. Cohort studies demonstrated that airflow limitation is a predictor of cardiovascular risk, even after adjusting for known risk factors such as smoking and cholesterol levels. Various mechanisms of vascular damage have been suggested in COPD including systemic inflammation, hypoxia, oxidative stress, activation of the sympathetic nervous system and changes of the vascular connective tissue. The evidence of a causal relationship between COPD and cardiovascular disease is yet insufficient. Data from controlled trials investigating the postulated pathomechanisms are awaited with interest

    BACKGROUND: Duchenne muscular dystrophy (DMD) leads to progressive impairment of muscle function, respiratory failure and premature death. Longitudinal data on the course of physical disability and respiratory function are sparse. OBJECTIVES: To prospectively assess physical impairment and disability, respiratory function and survival in DMD patients over several years in order to describe the course of the disease with current care. METHODS: In 43 patients with DMD, aged 5-35 years, yearly assessments of physical disability by the Duchenne muscular dystrophy physical Impairment and Dependence on care (DID) score ranging from 9 (no disability) to 80 (complete dependence), and forced vital capacity (FVC) were obtained over a mean +/-SD time interval of 5.4 +/-2.1 years. RESULTS: DID scores were correlated with age according to a hyperbolic function (f=85.3*age/(10.05+age), R=0.62, P<0.0001). FVC declined exponentially with age (f=139.1*exp(-0.08*age)), R=0.52, P<0.0001. Mean +/-SD age at which patients lost their ambulation was 9.4 +/-2.4 years and they became dependent on an electro-wheelchair at 14.6 +/-4.0 years. The age at beginning of assisted ventilation was 19.8 +/-3.9 years, Three patients deceased during the observation period. The estimated probability of survival to age 30 years was 85%, median survival was 35 years. CONCLUSIONS: Our detailed observations of the progression of physical disability, dependence on care and respiratory impairment in DMD patients from childhood to adult life is valuable for predicting the clinical course with current medical care. Compared to historical data, survival has considerably improved
