Varicella zoster virus (VZV) is an exclusively human neurotropic alphaherpesvirus. Primary infection causes varicella (chickenpox), after which virus becomes latent in ganglionic neurons along the entire neuraxis. With advancing age or immunosuppression, cell-mediated immunity to VZV declines and virus reactivates to cause zoster (shingles), which can occur anywhere on the body. ⋯ Immunocompromised patients require intravenous acyclovir. First-line treatments for post-herpetic neuralgia include tricyclic antidepressants, gabapentin, pregabalin, and topical lidocaine patches. VZV vasculopathy, meningoencephalitis, and myelitis are all treated with intravenous acyclovir.

Chronic obstructive pulmonary disease (COPD) is characterised by progressive airflow limitation in the presence of identifiable risk factors. Inflammation is the central pathological feature in the pathogenesis of COPD. In addition to its pulmonary effects, COPD is associated with significant extrapulmonary manifestations, including ischaemic heart disease, osteoporosis, stroke and diabetes. ⋯ Smoking cessation is paramount in managing COPD, with promotion of physical activity and pulmonary rehabilitation being other key factors in management. Comorbidities should be actively sought and managed in their own right. Given the chronicity and progressive nature of COPD, ongoing monitoring and support with timely discussion of advanced-care planning and end-of-life issues are recommended.

Bacteremia in the Patients With Acute Pancreatitis as Revealed by 16S Ribosomal RNA Gene-Based Techniques.
To define the characteristic of bacteremia in the patients with acute pancreatitis and determine its possible association with the disease severity. DESIGN:: A prospective controlled study. SETTING:: ICU of Jinling Hospital, China. PATIENTS:: A total of 48 patients with mild or severe acute pancreatitis were enrolled in this study. INTERVENTIONS:: None. MEASUREMENTS AND MAIN ⋯ This study provides a detailed description on the prevalence of bacteremia and characteristic of bacterial species in patients with acute pancreatitis. We demonstrate an association between the bacteremia and the disease severity, which enables us to better understand a potential role of bacterial translocation in the pathogenesis of septic complication in acute pancreatitis.

Venous leg ulceration is associated with pain and poor health-related quality of life (HRQL). The purpose of this study was to identify demographic and clinical characteristics associated with pain and decreased HRQL in patients with active venous ulcers. ⋯ Research is needed to test strategies to reduce pain and possibly improve HRQL in high risk groups.
