Kounis syndrome was described in 1991 by Kounis and Zavras as the coincidental occurrence of acute coronary syndromes with allergic reactions (anaphylactic or anaphylactoid). Today, allergic angina and allergic myocardial infarction are referred to as Kounis syndrome, and the latter has been reported in association with a variety of drugs, insect stings, food, environmental exposures and medical conditions, among other factors. The incidence is not known, as most of the available information comes from case reports or small case series. In this article, the clinical aspects, diagnosis, pathogenesis, related conditions and therapeutic management of the syndrome are discussed.

Cardiovascular failure is a common disorder in critical care medicine. When admitted to the ICU, patients with hemodynamic deterioration should be examined rapidly to correctly assess the main determinants of cardiovascular function (preload, afterload and contractility). This review examines the assessment of contractility and afterload involving the combined use of several hemodynamic monitors, which allows different approaches to the same problem, with a view to improving the efficiency of management and treatment in critically ill patients.

To determine whether the alveolar-arterial oxygen gradient (Grad[A-a]O₂) helps confirm the influence of PEEP on PaFi (PaO₂/FiO₂). ⋯ By adding PEEP to the PaFi model (PaFip), we clearly improve the latter, as reflected by a better goodness of fit.

To describe the incidence and main clinical characteristics of barotrauma during open lung ventilation (OLV). ⋯ Barotrauma was an exclusive complication of patients with primary lung injury, and the incidence in this group was high. In most cases, there were only radiological findings without clinical significance that did not require the suspension of OLV. Barotrauma was neither related to high pressures and volumes nor associated with increased mortality.

There is a growing body of evidence that early management of patients with acute pancreatitis may alter the natural course of disease and improve outcomes of patients. The aim of this paper is to optimize the management of patients with acute pancreatitis during the first 72 h after hospital admission by proposing several clinical care pathways. ⋯ Further studies will need to assess whether the adoption of these pathway reduces mortality and morbidity in patients with acute pancreatitis. The previous SEMICYUC guidelines on management of patients with acute pancreatitis in Intensive Care will need to be revised to reflect the recent developments in the field.
