Continuous psoas and sciatic block after knee arthroplasty: good effects compared to epidural analgesia or i.v. opioid analgesia: a prospective study of 63 patients.

Introduction: For endoprosthetic knee surgery, intensive postoperative pain therapy is necessary. We therefore evaluated whether the combination of continuous psoas compartment and sciatic analgesia (PSC) is as effective as epidural analgesia (EPI) and whether it provides better analgesia than patient-controlled intravenous analgesia with piritramide (PCA).

Methods: We studied 63 patients who underwent total knee arthroplasty (TKA).

Influence of somatostatin receptor scintigraphy and CT/MRI on the clinical management of patients with gastrointestinal neuroendocrine tumors: an analysis in 188 patients.

Aim: Many studies describe the sensitivities and specificities of computed tomography (CT), magnetic resonance imaging (MRI), and somatostatin receptor scintigraphy (SRS) in patients with gastrointestinal neuroendocrine tumors (GNT). We performed a study to evaluate the influence of these techniques on the therapeutic management of patients with advanced stages of GNT.

Patients And Methods: The results of either CT/MRI scans or SRS were reviewed by two independent observers who decided on the therapy of a patient.
