When and how to treat invasive fungal infections (IFIs) is discussed in this review, with a focus on the two most prevalent non-endemic IFIs, namely invasive aspergillosis and invasive candidiasis. Early treatment initiation in patients with IFIs has a profound impact on mortality rates, but reliable diagnostic measures are lacking. This situation has led to the parallel use of different treatment strategies, e.g. prophylaxis, empirical and pre-emptive treatment, as well as targeted treatment in response to a definite diagnosis of IFI. ⋯ LAmB is a second-line treatment option in both settings. Early diagnosis of IFIs is imperative to facilitate treatment success. In all patients at risk for IFIs, blood cultures, galactomannan antigen and diagnostic imaging should be rigorously enforced.

Oral pregabalin, a calcium channel alpha(2)delta-subunit ligand with analgesic, anxiolytic and antiepileptic activity, has shown efficacy in the treatment of fibromyalgia. It has a multidimensional effect in the treatment of this complex condition, and is associated with rapid and clinically significant improvements in several outcome measures relating to core symptoms of the syndrome, including pain and sleep, in patients with long-standing fibromyalgia. ⋯ The most common adverse events associated with the drug are dizziness and somnolence, which are generally mild to moderate in intensity and are tolerated by many patients. Pregabalin is, therefore, a valuable option in the first-line treatment of patients with fibromyalgia.

Dalbavancin is a semisynthetic glycopeptide antibacterial agent that is active against Gram-positive bacteria associated with complicated skin and skin structure infections (cSSSIs). It is administered as a two-dose regimen intravenously infused over 30 minutes once weekly. The efficacy of dalbavancin (1000 mg on day 1 and 500 mg on day 8) has been examined in two randomized controlled trials in adults with cSSSIs. ⋯ In a randomized, controlled, double-blind, multinational, phase III trial, dalbavancin was noninferior to linezolid, with clinical success rates of 88.9% and 91.2%. In a randomized, open-label, multicentre, phase II trial, clinical success rates were 94% with dalbavancin and 76% with comparator antibacterials. Dalbavancin was generally well tolerated by adult patients with cSSSIs, with most adverse events being of mild or moderate severity.

Following the initial resuscitation of burn patients, the pain experienced may be divided into a 'background' pain and a 'breakthrough' pain associated with painful procedures. While background pain may be treated with intravenous opioids via continuous infusion or patient-controlled analgesia (PCA) and/or less potent oral opioids, breakthrough pain may be treated with a variety of interventions. The aim is to reduce patient anxiety, improve analgesia and ensure immobilization when required. ⋯ At least one individual who is capable of establishing a patent airway and positive pressure ventilation, as well as someone who can call for additional assistance, should always be present whenever analgo-sedation is administered. Oxygen should be routinely delivered during sedation. Blood pressure and continuous ECG monitoring should be carried out whenever possible, even if a patient is undergoing bathing or other procedures that may limit monitoring of vital pulse-oximetry parameters.

Cigarette smoke, a toxic collection of more than 4000 chemicals generated from combustion of tobacco plant leaves, is known to cause several respiratory ailments, including chronic bronchitis, emphysema and lung cancer, and is associated with an increase in respiratory infections. In addition, cigarette smoking is considered a principal aetiological factor responsible for the development of certain diffuse interstitial and bronchiolar lung diseases, namely respiratory bronchiolitis-interstitial lung disease (RB-ILD), desquamative interstitial pneumonia (DIP) and adult pulmonary Langerhans' cell histiocytosis (PLCH). Although not exclusively seen in cigarette smokers, substantial clinical and epidemiological data support a central role for smoking as the primary causative agent of most RB-ILD, DIP and PLCH. ⋯ Recent studies also suggest a role for cigarette smoking as a potential co-factor in the development of acute eosinophilic pneumonia, usual interstitial pneumonia and rheumatoid arthritis-associated interstitial lung disease. In the current review, we propose a novel classification that takes into account the complex relationship between cigarette smoking and diffuse lung diseases. Investigation on the role of smoking as a potential causative factor or modifier of these diverse diffuse lung diseases is important, as smoking cessation utilizing state-of-the-art tobacco cessation efforts should be a central part of therapy, while pharmacotherapy with corticosteroids or other immune modifying agents should be reserved for selected patients.
