Acute varicella zoster virus (VZV) infection, or chickenpox, is still perceived by many as a mild infection of childhood. However, chickenpox is increasingly common in adults and adolescents who together with immunosuppressed individuals are at a higher risk of severe infection. Antiviral therapy is available which both ameliorates symptoms and decreases the severity of chickenpox if administered early in the course of the infection. ⋯ Active immunisation is available and is universal in many developed countries. This review reflects current best practice in management of chickenpox in adults by specialist physicians in the UK. The accompanying flowchart has been formulated to guide emergency physicians and general practitioners through the decision-making process regarding treatment and admission for specialist care.

Infective endocarditis in an urban medical center: association of individual drugs with valvular involvement.
Injection drug users (IDUs) develop more right-sided infective endocarditis (IE) than non-IDUs, but it is not known whether this risk is specific to any particular injected drug. This study reviews the clinical characteristics of IE in an urban population and examines the association of drug type with manifestations of IE. ⋯ The epidemiology of IE in this cohort is different from that reported recently in other cohorts, likely due to the high prevalence of IDU. Heroin use may underlie the association between IDU and right-sided endocarditis.

Severe sepsis and diabetes mellitus have additive effects on red blood cell deformability.
Diabetes mellitus is accompanied by microvascular complications leading to organ dysfunction, while sepsis is a major cause of morbidity and mortality in diabetics. We addressed the hypothesis that red blood cell (RBC) deformability may be additively compromised in septic diabetic patients, leading to a further impairment of microcirculation. ⋯ The presence of diabetes mellitus seems to affect the already compromised RBC deformability of septic patients, probably leading to serious microcirculatory functional impairments in septic diabetic patients.
