Degenerative mitral regurgitation in elderly patients and functional mitral regurgitation secondary to severe left ventricular dysfunction are not easy options for conventional surgery. Recently, a new percutaneous approach has been proposed with the MitraClip®, based on the Alfieri edge-to-edge repair technique. The aim of the study is to report, compare and discuss the results of two multicenter randomized trials: MITRA. ⋯ The conflicting results of the two trials may have many explanations, but probably the main cause is the most stringent inclusion criteria in COAPT. The effective reduction of mitral regurgitation and improvement in exercise capacity already observed in registries including more than 70,000 patients was confirmed in a randomized trial with improvement observed in hard end-points. This has already led to an extension of FDA approval to functional regurgitation and a more liberal use across the world.

Although ketamine has been used for procedural sedation and analgesia, some researchers have assessed ketamine-propofol as a better alternative because of its reduced adverse events. The goal of this review was to compare adverse events between ketamine-propofol and ketamine for procedural sedation and analgesia in children. We searched the literature from their inception to May 2018 without the restriction of language. ⋯ In regard to nausea and vomiting, ketamine-propofol was significantly effective (RR 0.43, 95% CI 0.25-0.74). In addition, we could not demonstrate differences in efficacious sedation between ketamine-propofol and ketamine. Although our study was not able to demonstrate differences in efficacious sedation between ketamine-propofol and ketamine, we confirmed that ketamine-propofol sedation had a lower frequency of adverse events compared to ketamine sedation in children.

Intravenous immunoglobulins are the cornerstone for the treatment of primary humoral immunodeficiencies and may be used for a great number of other autoimmune, neurological and hematological conditions as well. Given their wide application, the possibility of running across a patient who needs this kind of therapy is becoming increasingly common. ⋯ However, numerous adverse reactions ranging from mild to severe have been reported and linked to patient- and product-related factors. For all these reasons, we present herein a comprehensive review of the on- and off-label applications of intravenous immunoglobulins and provide a guide for the internist how to minimize the risk of adverse reactions and manage them.

Sickle cell disease (SCD) is the most important hemoglobinopathy worldwide in terms of frequency and social impact, recently recognized as a global public health problem by the World Health Organization. It is a monogenic but multisystem disorder with high morbidity and mortality. ⋯ This review focuses both on "time-dependent" acute clinical manifestations of SCD and chronic complications commonly described in adults with SCD. The review covers a broad spectrum of topics concerning current management of SCD targeted at the internists and emergency specialists who are increasingly involved in the care of acute and chronic complications of SCD patients.
