Bacterial meningitis in adults is a severe disease with high fatality and morbidity rates. Experimental studies have shown that the inflammatory response in the subarachnoid space is associated with an unfavourable outcome. In these experiments, corticosteroids, and in particular dexamethasone, were able to reduce the inflammatory cascades in the subarachnoid space. ⋯ On the basis of the available evidence, adjunctive dexamethasone therapy should be initiated before or with the first dose of antibacterials and continued for 4 days in all adults with suspected or proven bacterial meningitis, regardless of bacterial aetiology. In patients with both meningitis and septic shock, dexamethasone therapy cannot be unequivocally recommended, but the use of lower doses seems reasonable at present. Since prompt use of dexamethasone and appropriate antibacterials improves the prognosis of adults with bacterial meningitis, hospitals will require protocols to include dexamethasone with the initial antibacterial therapy.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of budesonide and formoterol in one pressurised metered-dose inhaler in adults and adolescents with moderate to severe asthma: a randomised clinical trial.
Inhaled corticosteroids (ICSs) are the preferred maintenance therapy for adults and children with mild, moderate and severe persistent asthma, with the addition of a long-acting beta(2)-adrenoceptor agonist to ICS therapy recommended for patients with moderate or severe persistent asthma. The efficacy and safety of the combination of budesonide and formoterol delivered via dry powder inhaler (DPI) is well documented. ⋯ In this population, twice-daily budesonide/formoterol pMDI provides asthma control significantly greater than the monocomponents or placebo and comparable with budesonide pMDI + formoterol DPI. Safety profiles were similar for all treatments.

Review Comparative Study
Remifentanil : a review of its analgesic and sedative use in the intensive care unit.
Remifentanil (Ultiva), a 4-anilidopiperidine derivative of fentanyl, is an ultra-short-acting micro-opioid receptor agonist indicated to provide analgesia and sedation in mechanically ventilated intensive care unit (ICU) patients. Analgesia-based sedation with remifentanil is a useful option for mechanically ventilated patients in the ICU setting. Its unique properties (e.g. organ-independent metabolism, lack of accumulation, rapid offset of action) set it apart from other opioid agents. ⋯ Moreover, it allows fast and predictable extubation, as well as being associated with a shorter duration of mechanical ventilation and quicker ICU discharge than comparators in some studies. In addition, remifentanil is generally well tolerated in this patient population. Thus, remifentanil is a welcome addition to the currently available pharmacological agents employed in the management of mechanically ventilated ICU patients.

Wegener's granulomatosis (WG) is the most common pulmonary granulomatous vasculitis and was a uniformly fatal disease prior to the identification of efficacious pharmacological regimens. The pathogenesis of WG remains elusive but proteinase 3-specific anti-neutrophil cytoplasmic antibodies may be involved. Histologically, WG is defined by the triad of small vessel necrotising vasculitis, 'geographic' necrosis and granulomatous inflammation. ⋯ Recent investigation has focussed on other immunomodulatory agents (tumour necrosis factor-alpha inhibitors [infliximab and etanercept] and anti-CD20 antibodies [rituximab]) for treating patients with WG. However, the current data are conflicting and difficult to interpret. As a result, these newer agents cannot be recommended for routine use until vigorous clinical study confirms their efficacy.

Remifentanil is a relatively new synthetic opioid, which is not licensed worldwide for neonates and infants. Because of its unique pharmacokinetic properties with a short recovery profile, it could be the ideal opioid for neonates and infants, who are especially sensitive to respiratory depression by opioids. Therefore, we conducted a MEDLINE search on all articles dealing with the use of remifentanil in this important subgroup of patients. ⋯ In approximately 300 neonates and infants, remifentanil proved to be an effective and safely used opioid for this indication. However, very limited data exist on remifentanil for analgesia and sedation of mechanically ventilated paediatric intensive care patients. Further research with remifentanil in neonates and infants should focus on this group of patients because remifentanil, with its very short context-sensitive half-life, could result in shorter extubation times compared with commonly used opioids such as morphine or fentanyl.
