Case Reports
Gas gangrene pyaemia with myocardial abscess formation--fatal outcome from a rare infection nowadays.
We report a case of sudden death after gas gangrene. A 67-year-old male patient with diabetes mellitus and chronic renal failure (on haemodialysis three times a week) presented in the surgical emergency department with a severe swelling and crepitation in the right groin. No signs of trauma were present-except for a well-healed, 1-year-old scar after femoro-popliteal bypass surgery. ⋯ Abscess formation was found in the myocardium. Clostridial gas gangrene is a rare clinical condition. Unless immediate diagnosis and adequate therapy measures are taken, the outcome and chances for survival are poor as demonstrated by this case.

A total of 494 participants who were scheduled to take Baskent University's basic life support (BLS) training programme in 2001-02 were asked to complete a 25-item questionnaire prior to the course. The questionnaire investigated the demographic characteristics of the subjects, their knowledge of the theoretical and practical aspects of BLS, and personal experience and attitudes related to BLS. The 'non-medical group' included 179 laypersons, and the 'medical group' was composed of medical students (n=220), residents (n=69) and clinical nurses (n=26). ⋯ Compared to the other participants, individuals with previous emergency experience, and those who had previous BLS training answered significantly more of the theoretical questions correctly. However, neither of these groups performed significantly better than the other participants in the practical questions (P>0.05 for both comparisons). Based on our findings, we recommend that BLS training for medical undergraduates, other medical personnel and laypersons be improved and standardized throughout Turkey.

Meta Analysis
Biphasic and monophasic shocks for transthoracic defibrillation: a meta analysis of randomised controlled trials.
Biphasic waveforms are routinely used for implantable defibrillators. These waveforms have been less readily adopted for external defibrillation. This study was performed in order to evaluate the efficacy and harms of biphasic waveforms over monophasic waveforms for the transthoracic defibrillation of patients in ventricular fibrillation (VF) or haemodynamically unstable ventricular tachycardia. ⋯ Biphasic waveforms defibrillate with similar efficacy at lower energies than standard 200 J monophasic waveforms, and greater efficacy than monophasic shocks of the same energy. Available data suggests that lower delivered energy and voltage result in less post-shock myocardial injury.
