The value of ultrasound-guided biopsy of fluorodeoxy-glucose positron emission tomography (FDG-PET)-positive supraclavicular lymph nodes in patients with suspected lung cancer.

Background: Accurate lymph node staging is essential for adequate prognostication and therapy planning in patients with non-small cell lung cancer (NSCLC). FDG-PET/CT is a sensitive tool for the detection of metastases, including non-palpable supraclavicular lymph node (SCLN) metastases. Histological proof of metastatic spread and mutation analysis is crucial for optimal staging and therapy.

Ultrasound-guided carotid sheath block for carotid endarterectomy: a case series of the spread of injectate.

Introduction: We aimed to show the spread of local anesthetic following an ultrasound-guided, double-injection technique of a carotid sheath block before carotid endarterectomy.

Methods: The study included 15 patients scheduled for elective carotid endarterectomy. The carotid sheath block was performed after ultrasound-guided localization of the carotid bifurcation (level C4-C6) at the posterior border of the sternocleidomastoid muscle.

Imaging non-specific wrist pain: interobserver agreement and diagnostic accuracy of SPECT/CT, MRI, CT, bone scan and plain radiographs.

Purpose: Chronic hand and wrist pain is a common clinical issue for orthopaedic surgeons and rheumatologists. The purpose of this study was 1. To analyze the interobserver agreement of SPECT/CT, MRI, CT, bone scan and plain radiographs in patients with non-specific pain of the hand and wrist, and 2.

Guanylyl cyclase activator ataciguat improves vascular function and reduces platelet activation in heart failure.

Introduction: Endothelial dysfunction and platelet activation due to impaired endogenous platelet inhibition by nitric oxide (NO) are part of the cardiovascular phenotype in congestive heart failure (CHF). We investigated whether chronic activation of the NO target enzyme soluble guanylyl cyclase (sGC) would beneficially modulate vascular function and platelet activation in experimental CHF.

Materials And Methods: Chronic myocardial infarction was induced by coronary ligation in male Wistar rats.
