Pseudomonas aeruginosa (Pa) is the predominant pathogen infecting the airways of patients with cystic fibrosis (CF). Initial colonization is usually transient and associated with non-mucoid strains, which can be eradicated if identified early. This strategy can prevent, or at least delay, chronic Pa infection, which eventually develops in the majority of patients by their late teens or early adulthood. This article discusses the management and latest treatment developments of Pa lung infection in patients with CF, with a focus on nebulized antibiotic therapy. ⋯ Current challenges in the management of CF patients with chronic Pa lung infection are numerous. The availability of novel anti-pseudomonal antibiotic formulations/devices is anticipated to improve treatment adherence in patients with CF, and could improve clinical outcomes. Thus, there is hope for improved survival in individuals with CF suffering from chronic pulmonary infection with Pa.

Venous thromboembolism (VTE) and its long-term secondary complications are major health problems associated with high rates of morbidity and mortality and considerable costs for healthcare systems. Many patients receive suboptimal therapy, despite the availability of established and effective agents (including low molecular weight heparins, unfractionated heparin, fondaparinux and vitamin K antagonists) and evidence-based, internationally recognised guidelines. Limited knowledge of guidelines, concerns about bleeding risks and the inconvenience of parenteral administration and routine coagulation monitoring contribute to non-adherence to guidelines. Newer oral anticoagulants such as rivaroxaban, dabigatran etexilate, apixaban and edoxaban, which do not have the limitations of established anticoagulants, have been developed. ⋯ Based on results of completed trials, rivaroxaban and dabigatran both may reduce the incidence of secondary complications of VTE and associated socioeconomic costs. Introduction of these newer anticoagulants is likely to have a substantial impact on clinical practice.

The topical 5% lidocaine medicated plaster is recommended as first-line treatment for localized peripheral neuropathic pain. ⋯ Treatment of several, primarily neuropathic and mixed-pain conditions with the 5% lidocaine medicated plaster was found efficacious and safe. Further controlled studies, in particular where only small open-label studies or case reports are available, should be considered.

This open-label, phase 3b study evaluated the effectiveness and tolerability of tapentadol prolonged release and tapentadol immediate release (for acute pain episodes) for severe, chronic low back pain with or without a neuropathic pain component that was inadequately managed in patients taking World Health Organization (WHO) Step I or II analgesics or who were not regularly treated with analgesics. ⋯ Tapentadol prolonged release was well tolerated and effective for managing severe, chronic low back pain with or without a neuropathic pain component.

Long-term safety and efficacy of ambrisentan in Japanese adults with pulmonary arterial hypertension.
To investigate the safety and efficacy of long-term administration of ambrisentan in Japanese adults with pulmonary arterial hypertension (PAH). ⋯ Our results suggest that long-term administration of ambrisentan is well tolerated and efficacious for Japanese adults with PAH.
