Case ReportsPurpura fulminans associated with Lactobacillus paracasei liver abscess.
Purpura fulminans is a rare but devastating haemorrhagic condition often associated with sepsis. Many different organisms have been implicated in the aetiology of purpura fulminans, most commonly Neisseria meningitidis and Streptococcus pneumoniae. We report a case of purpura fulminans associated with Lactobacillus paracasei liver abscess. Purpura fulminans has not previously been associated with this organism and specific bacteriological testing was used to exclude the presence of other species.

Comparative StudyTrends in intra-aortic balloon counterpulsation: comparison of a 669 record Australian dataset with the multinational Benchmark Counterpulsation Outcomes Registry.
The aim of this study was to review and describe indications for intraaortic balloon counterpulsation (IABP) use and identify the impact these have on outcomes at an Australian cardiothoracic tertiary referral hospital. A secondary aim was comparison of the Australian practice with a large multinational IABP data registry. Patient demographics, IABP indication, IABP complication rate and mortality in 662 patients treated with IABP at The Prince Charles Hospital (TPCH), Brisbane, between January 1994 and December 2004 inclusive were compared with The Benchmark Counterpulsation Outcomes Registry. ⋯ TPCH indications for IABP were: weaning from cardiopulmonary bypass (34.2%); cardiogenic shock (24.4%); preoperative support (13%); catheter laboratory support (10.6%); refractory ventricular failure (7.3%); ischaemia related to intractable ventricular arrhythmias (4.5%); unstable refractory angina (4%); mechanical complications due to acute myocardial infarction (1.2%) and other (0.4%) (0.4% not reported). In comparison to Benchmark, IABP at TPCH demonstrated a prejudice toward intraoperative use (34.2% versus 16.6%; P < or = 0.0001) and an aversion to catheter laboratory support (10.6% versus 19%; P < or = 0.0001). TPCH and Benchmark IABP outcomes demonstrated comparable mortality (22% versus 20.8%; P = ns) but increased TPCH complications (10.3% vs. 6.2%; P < or = 0.0001) owing to a 2% difference in observed insertion site bleeding.

Case ReportsTranstracheal lignocaine: effective treatment for postextubation stridor.
Three cases of post-extubation stridor due to suspected laryngospasm are described in which a small dose of lignocaine injected intra-tracheally, through the cricothyroid membrane, produced rapid and effective relief of stridor with no early recurrence or side-effects. The procedure was performed safely and quickly and was well tolerated by patients. Trans-tracheal injection of local anaesthetic should be considered for treatment of post-extubation stridor in adults, so long as there is no risk of pulmonary aspiration, and pathological causes of laryngospasm have been excluded.
