    Treatment of acute organophosphorus (OP) insecticide poisoning is difficult, with many patients dying despite best care. Pre-clinical studies have shown benefit from salbutamol, possibly due speeding alveolar fluid clearance or reducing bronchoconstriction. In this small pilot dose-response study, we aimed to explore whether addition of nebulized salbutamol to standard care might improve resuscitation.We performed a single-blind phase II study comparing the effect of two different doses of nebulized salbutamol versus saline placebo, in addition to standard treatment. Primary outcome was oxygen saturations over the first 60 min of resuscitation; secondary outcomes included heart rate, incidence of dysrhythmias, time to 'atropinization', atropine dose required, and mortality.Seventy-five patients were randomized to receive 5 mg (Salb5, n = 25) or 2.5mg (Salb2.5, n = 25) of salbutamol, or saline placebo (NoSalb, n = 25), by nebulizer. Oxygen saturations did not differ between groups over the first 60 min of resuscitation (median AUC NoSalb: 1376 [95% CI 1282 to 1470], Salb2.5: 1395 [1305 to 1486], Salb5: 1233 [1100 to 1367]; p = .9898). Heart rate was also similar across the three arms. Median time to full atropinization, and atropine dose required, were the same for all three arms (NoSalb 15.0 [10-16] min and 12.6 [8.0-13.4] mg, Salb2.5 15.0 [10-16] min and 12.6 [9.3-16.8] mg, and Salb5 15.0 [10-20] min and 12.6 [10.7-20.6] mg; p = .4805 and p = .1871, respectively). Three (12%) patients died in the Salb2.5 and Salb5 groups and two (8%) in the NoSalb group.This pilot study, within the limitations of its small size and variation between patients, found no apparent evidence that administration of nebulized salbutamol improved resuscitation of patients with acute OP insecticide self-poisoning. The data obtained provides a basis to design further studies to ultimately test the role of salbutamol in OP insecticide poisoning

    Wasp stings (Vespa affinis) induced acute kidney injury following rhabdomyolysis in a 25-year-old woman

    Wasp sting is a relatively common arthropod assault. This usually results in pain and mild allergic reactions, but sometimes may cause severe systemic reaction and multiorgan dysfunction including rhabdomyolysis, hemolysis, coagulopathy, hepatic, renal and cardiac complications. Along with several other pathomechanisms, rhabdomyolysis is a distinguished cause of acute kidney injury (AKI) in patients with wasp sting. We herein report a case in which the patient developed rhabdomyolysis followed by AKI due to multiple wasp stings. The offending wasp was brought to the hospital and the species was confirmed by a zoologist (Vespa affinis)
