Hemophagocytic lymphohistiocytosis (HLH), also known as hemophagocytic syndrome or macrophage activation syndrome within a pre-existing rheumatological disease, remains undiagnosed in over 70% of all cases in intensive care units (ICU) due to the sepsis-like clinical presentation. This report describes the case of a 30-year-old previously healthy male patient who was admitted to the normal infectiology ward of the Charité - Universitätsmedizin Berlin with unclear fever after a 3‑month journey around Asian and South America. ⋯ Furthermore, the current diagnostic and therapeutic options are discussed. Ferritin is a decisive diagnostic marker that should be determined in every patient with unclear organ failure.

The determination of arterial blood pressure is a fundamental part of basic cardiovascular monitoring in perioperative, intensive care and emergency medicine. Blood pressure can be measured directly via an arterial catheter, which is the most accurate method. ⋯ Furthermore, methods such as the vascular unloading technique with a finger plethysmographic sensor are available for continuous and noninvasive blood pressure monitoring. This article explains the principles of the individual methods, the sources of errors, advantages and disadvantages and discusses the fields of application in the clinical routine.

Charging defibrillators prior to analyzing heart rhythms may decrease the no-flow time during rhythm check pauses while resuscitating in cardiac arrest. Although this anticipatory method is already used in some centers little is known about its safety. This study was carried out to confirm the safety and feasibility of the anticipatory method. It was hypothesized that this anticipatory method results in shorter total no-flow times, while other parameters of defibrillation efficacy including defibrillator safety and minimization of peri-shock pauses are unchanged. ⋯ Charging defibrillators before rhythm analysis did not decrease total no-flow time in simulated cardiac arrests but resulted in significantly longer peri-shock pauses exceeding 5 s. No significant differences in defibrillation safety were observed between the groups.
