Over the past few years, Serotonin Syndrome (SS) has become a significant clinical concern. Over the last decade, United States saw a surge in antidepressant use. SS characteristically presents as the triad of altered mental status, autonomic dysfunction and neuromuscular excitation. Symptoms vary from patient to patient with mild cases presenting with subacute symptoms and severe cases progressing rapidly to death. Due to the protean manifestations of the syndrome along with non-specific prodromal, SS can easily be misdiagnosed if not carefully assessed. In severe cases, SS can be mistaken as neuroleptic malignant syndrome while mild cases are mostly misattributed to other causes such as flu. SS is a clinical diagnosis and therefore, requires a thorough review of medications and physical examination. Given the protean nature of this toxicologic syndrome various criteria were defined which includes Sternbach's, Radomski and Hunter's criteria. Keeping in mind the wide symptoms of serotonin syndrome from being barely perceptible to lethal emphasis there is a need to treat the syndrome on urgent basis. Mainstay for treatment of serotonin syndrome is to discontinue the offending drug. Improvement is seen in most patients within 24 hours.

Dietary changes are a major lifestyle factor that can influence the progression of chronic diseases such as diabetes. Recently, flavanols, a subgroup of plant-derived phytochemicals called flavonoids, have gained increasing attention, due to studies showing an inverse correlation between dietary intake of flavanols and incidence of diabetes. Flavanoids in the cocoa plant may ameliorate insulin resistance by improving endothelial function, altering glucose metabolism, and reducing oxidative stress. Oxidative stress has been proposed as the main culprit for insulin resistance. The well-established effects of cocoa on endothelial function also points to a possible effect on insulin sensitivity. The relationship between insulin resistance and endothelial function is a reciprocal one. Overall, the evidence from these studies suggests that cocoa may be useful in slowing the progression to type 2 diabetes and ameliorating insulin resistance in metabolic syndrome. Additionally, results from several small studies indicate that cocoa may also have therapeutic potential in preventing cardiovascular complications in diabetic patients. Studies highlighting the potential of cocoa-containing diets, in large-randomized controlled trials should be performed which might give us a better opportunity to analyze the potential health-care benefit for reducing the risk of complications in diabetic patients at molecular level.

Drug-eluting stents have significantly improved the long-term outcomes of percutaneous coronary intervention (PCI) by decreasing the excessive growth of neointima. However, conventional stents have some limitations. PCI with a bioresorbable vascular scaffold (BVS) has emerged as an alternative since the presence of the prosthesis in the coronary artery is transient. A US Food and Drug Administration advisory panel of experts recommended approval of BVS based on the analysis of its risks and rewards in July 2016. In June 2017, the preliminary results of the Amsterdam Investigator-initiateD Absorb Strategy All-comers (AIDA) trial were released. This randomized controlled trial compared an everolimus-eluting BVS with an everolimus-eluting metallic stent in the context of routine clinical practice. The preliminary results revealed no significant difference in target-vessel failure when BVS was compared with metallic stenting. However, during the 2 years of follow-up, BVS was associated with a higher rate of device thrombosis. This is seen as an important development in the trial. There are some concerns regarding stent thrombosis and the restoration of real vessel functionality in the long term. For these reasons, for now, metallic stents remain the treatment of choice for PCI.
