Indications for pacemaker and implantable cardioverter defibrillator (ICD) implantations are rapidly expanding. Hence, device-related complications have increased the need for lead extraction. Lead extractions are performed percutaneously or by open surgery. We present a patient with isolated left ventricular noncompaction cardiomyopathy suffering from ICD pulse generator pocket and lead infect...

The extraction of impurities from illegally produced 3,4-methylenedioxymethamphetamine (MDMA) has been studied in order to optimize the parameters. Two different MDMA samples were used. Particular attention was paid to the influence of the pH, the evaporation step, and the sample storage. The method used was an extraction of impurities by diethyl ether from a buffer solution at pH 11.5, followe...

The predictive role of high-sensitivity C-reactive protein (hs-CRP), number of tooth extractions, and oral infections for mortality in people with and without diabetes is unclear. This prospective cohort study is a 12 1/2-year follow-up of the Oslo II study, a health survey in 2000. In all, 12,764 men were invited.

For the determination of silicon (Si) contents in plant materials several methods are use, but as all these exhibit specific advantages and drawbacks, none them has become prevalent. Alkaline chemicals widely used to extract Si from samples, because this method is comparably simple, fast, cheap. However, a comprehensive comparison between different alkaline extractions organs still missing, wel...
