Cellular composition of stent-penetrating tissue.

Background: A surprisingly low number (< 20%) of relevant (> 75%) restenoses occur in exophytic lesions after treatment with uncovered metal stents. The goal of this study was to investigate whether radial stent forces can exert localized influence on tumor growth.

Patients And Methods: In 17 patients, intraluminal tumor tissue was histologically investigated before and 1 week after stent implantation.

[Anti-obstructive anti-inflammatory therapy: no problems in pneumology, problematic in cardiology?].

Background: Treatment options for bronchial asthma and chronic obstructive pulmonary disease (COPD) are similar and can achieve adequate improvement or even control of symptoms with a relatively low risk of side effects. CARDIOVASCULAR SIDE EFFECTS OF BETA-AGONISTS: However, cardiovascular co-morbidities which increase with age lead to an increasing prevalence of therapy-related side effects especially when long- and short-acting beta 2-agonists and theophylline are being used. Both drugs can also mediate unwanted side effects on the heart.
