[Violence against ambulance staff].

Background: Attacks against emergency medical services are increasingly discussed in the media and in politics, which is reflected in political initiatives and legislative changes. However, there is a rather low number of scientific studies on this topic in Germany that do not represent a consistent image of prevalence. The current article addresses prevalence and situational escalation factors as well as consequences of the incidents and wishes of the emergency medical services regarding attacks.

Tonometry in corneal edema after cataract surgery: dynamic contour tonometry versus Goldmann applanation tonometry.

Introduction: Intraocular pressure (IOP) determination using dynamic contour tonometry (DCT) has been considered to be independent of central corneal thickness (CCT), while Goldmann applanation tonometry (GAT) is known to be influenced by various corneal properties. In this study, IOP was measured before and 1 day after cataract surgery using GAT and DCT to investigate the possible effects of corneal edema on IOP measurements.

Methods: Thirty patients with advanced cataracts were included in a pilot study.

Ocular pulse amplitude before and after cataract surgery.

Purpose: To investigate the impact of cataract surgery on the association of the ocular pulse amplitude (OPA) and intraocular pressure (IOP) with respect to the interpretation of OPA as an estimate of ocular blood flow.

Methods: Twenty-four patients with cataract were included in a clinical study. OPA was measured using dynamic contour tonometry (DCT, Pascal(®), SMT Swiss Microtechnology AG, Switzerland).
