Periprosthetic infections are a leading cause of morbidity after total joint arthroplasty. Common pathogens include Staphylococcus aureus, streptococcus, enterococcus, Escherichia coli, and Pseudomonas aeruginosa. However, there are many cases in which rare bacteria are isolated. This case report describes a periprosthetic knee infection caused by Plesiomonas shigelloides. In the United States, P shigelloides and 2 other Vibrionaceae family members, Vibrio vulnificus and Vibrio parahaemolyticus, are most often contracted from eating raw oysters and shellfish. P shigelloides usually causes a self-limiting watery diarrhea, but in immunosuppressed people it can cause septicemia. In this case report, a chemically and biologically immunosuppressed man consumed raw oysters and developed P shigelloides septicemia and acute periprosthetic knee infection that required surgical intervention.

Despite the availability of multiple nonheparin anticoagulants for the treatment of heparin-induced thrombocytopenia (HIT), few data are available comparing the cost-effectiveness of these agents. This analysis is particularly important when considering differences in the risk of adverse effects, routes of administration, requirements for phlebotomy and laboratory monitoring, and overall drug costs. We conducted a cost-effectiveness analysis of argatroban, bivalirudin, and fondaparinux for the treatment of suspected HIT from the institutional perspective. A 3-arm decision-tree model was developed that employs standard practices for anticoagulation monitoring. We incorporated published data on drug efficacy and probability of HIT-related thromboembolism and major bleeding. We considered both institutional costs and average wholesale price (AWP) and performed probabilistic sensitivity analyses (PSA) to address any uncertainty in model parameters. Using institutional costs, fondaparinux prevailed over both argatroban and bivalirudin in terms of cost ($151 vs $1250 and $1466, respectively) and adverse events averted (0.9989 vs 0.9957 and 0.9947, respectively). Results were consistent when AWP was used, with fondaparinux being less expensive ($555 vs $3081 and $2187, respectively) and more effective in terms of adverse events averted (0.9989 vs 0.9957 and 0.9947, respectively). The PSA confirmed our findings using both institutional costs and AWP. In conclusion, fondaparinux subcutaneous injection afforded significant advantages in terms of cost savings and adverse events averted compared with IV argatroban or bivalirudin infusions. Our data strongly suggest potential cost savings with fondaparinux and underscore the critical need for larger clinical studies of fondaparinux in the treatment of suspected HIT. © 2016 by The American Society of Hematology.

Objective. To review published educational interventions focusing on medication non-adherence. Methods. A literature search was performed of educational articles on the topic of medication adherence. Data on interventions and learning assessments were abstracted for relevant studies meeting search criteria. Results. Twenty studies met inclusion criteria. Sixteen included pill-taking experiences with regimens of candies or placebos and varied in their inclusion of novel elements to highlight issues such as stigma, regimen complexity, and adherence measurement. Three studies involved interacting with the public. Qualitative and quantitative methods were used to assess a variety of learning outcomes. Conclusion. Pill-taking experiences can help future providers appreciate the complex logistics of medication-taking, but are less capable of addressing the psychosocial aspects of adherence. A promising area for learning is to interact with actual medication users to understand their experiences and perspectives. © 2017, American Association of Colleges of Pharmacy.

Hospital dermatology is often thought to be too cumbersome for the private practicing dermatologist to handle, leaving patients in our communities without needed care and our medical colleagues in the dark when it comes to diagnosing and/or managing skin disease in the hospitalized patient. This notion that "someone else will figure it out" undervalues our expertise as a specialty and threatens the appropriate health outcomes we knowingly understand patients deserve. In this manuscript, we intend to break down the hospital consult conceptually so as to make clear how simple it can be to help our physician colleagues and make an important impact upon patients at their most vulnerable time. © 2017 Frontline Medical Communications.

Background Since the release of the second-generation cryoballoon (CB2; Arctic Front Advance™, Medtronic Inc) and its design modifications with improved cooling characteristics, the technique, dosing, and complication profile is significantly different from that of the first-generation cryoballoon. A comprehensive report of CB2 procedural recommendations has not been reported. Objective The purpose of this study was to review the current best practices from a group of experienced centers to create a user's consensus guide for CB2 ablation. Methods/Results High-volume operators with a combined experience of more than 3000 CB2 cases were interviewed, and consensus for technical and procedural best practice was established. Conclusion Comprehensive review of the CB2 ablation best practice guide will provide a detailed technique for achieving safer and more effective outcomes for CB2 atrial fibrillation ablation. © 2015 Heart Rhythm Society.

Suvorexant a novel, orexin receptor antagonist was recently approved by the US Food and Drug Administration for the treatment of sleep onset and sleep maintenance insomnia in August 2014. Multiple animal and human studies support the efficacy, safety, and tolerability of suvorexant for patients of various profiles. Current recommendations advocate for a starting dose of 10 mg and a maximum dose of 20 mg, with cautious use in women, obese patients, and patients taking other CYP3A4 inhibitors. More head-to-head studies comparing suvorexant to other sedative-hypnotic therapies are needed to further delineate which patients will benefit the most from this medication over others. © 2016 Lee-Iannotti and Parish.

Budd-Chiari syndrome (BCS) refers to hepatic venous outflow obstruction that in severe cases can lead to acute liver failure prompting consideration of revascularization or transplantation. Here, a 22 year old female with angiographically proven BCS secondary to JAK2/V617F positive Polycythemia vera on therapeutic warfarin presented with acute liver failure (ALF). Imaging revealed a new, near complete thrombotic occlusion of the main portal vein with extension into the superior mesenteric vein. An emergent direct intrahepatic portocaval shunt (DIPS) was created and liver function promptly normalized. She has been maintained on rivaroxaban since that time. Serial assessment over 1 year demonstrated continued shunt patency and improved flow in the mesenteric vasculature on ultrasound as well as normal liver function. DIPS is a viable alternative in the treatment of ALF from BCS when standard recanalization is not feasible. Improved blood flow may also improve portal/mesenteric clot burden. While further investigation is needed, new targeted anticoagulants may be viable as a long term anticoagulation strategy. © 2016, Fundacion Clinica Medica Sur. All rights reserved.

Background Despite the significant burden of childhood asthma, little is known about prevention-oriented management before and after hospitalizations for asthma exacerbation. Objective To investigate the proportion and characteristics of children admitted to the intensive care unit (ICU) for asthma exacerbation and the frequency of guideline-recommended outpatient management before and after the hospitalization. Methods A 14-center medical record review study of children aged 2 to 17 years hospitalized for asthma exacerbation during 2012-2013. Primary outcome was admission to the ICU; secondary outcomes were 2 preventive factors: inhaled corticosteroid (ICS) use and evaluation by asthma specialists in the pre- and posthospitalization periods. Results Among 385 children hospitalized for asthma, 130 (34%) were admitted to the ICU. Risk factors for ICU admission were female sex, having public insurance, a marker of chronic asthma severity (ICS use), and no prior evaluation by an asthma specialist. Among children with ICU admission, guideline-recommended outpatient management was suboptimal (eg, 65% were taking ICSs at the time of index hospitalization, and 19% had evidence of a prior evaluation by specialist). At hospital discharge, among children with ICU admission who had not previously used controller medications, 85% were prescribed ICSs. Furthermore, 62% of all children with ICU admission were referred to an asthma specialist during the 3-month posthospitalization period. Conclusion In this multicenter study of US children hospitalized with asthma exacerbation, one-third of children were admitted to the ICU. In this high-risk group, we observed suboptimal pre- and posthospitalization asthma care. These findings underscore the importance of continued efforts to improve prevention-oriented asthma care at all clinical encounters. © 2015 American College of Allergy, Asthma & Immunology.

Cardiac magnetic resonance (CMR) with its higher spatial resolution is considered the gold standard for evaluating ventricular mass, volumes, and ejection fraction. CMR can be used for accurate diagnosis of several conditions, especially cardiomyopathies. The purpose of this article is to review the utility of CMR in the diagnosis and management of nonischemic cardiomyopathies. We have reviewed both common and rare types of nonischemic cardiomyopathies in detail and elaborated on the specific CMR findings in each. We believe that CMR is an invaluable tool, not only in differentiating nonischemic from ischemic cardiomyopathy, but also in aiding the accurate diagnosis and management of the subtype of nonischemic cardiomyopathy. CMR should routinely be integrated in the diagnostic workup of various cardiomyopathies. © 2015 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.
