Recent controlled clinical trials have demonstrated that long-term administration of 600 mg thioctic acid (TA, R(+)-TA, S([)-TA; a-lipoic acid), once daily, can improve symptoms of peripheral and autonomic neuropathy in patients with diabetes mellitus (Ziegler et al. 1995). In diabetic patients the bioavailability of drugs may be decreased by delayed(More)
BACKGROUND The effect of pleurectomy/decortication or extrapleural pleuropneumonectomy on pulmonary function has not yet been evaluated. The aim of this study was to determine the parameters of pulmonary function before and after pleurectomy/decortication or extrapleural pleuropneumonectomy. METHODS We conducted a review of 48 patients with unilateral(More)
BACKGROUND Lung cancer is highly aggressive and tends to metastasize early. Therefore, accurate mediastinal staging is important for therapeutic decision making. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a minimally invasive procedure for mediastinal lymph node sampling and cancer staging. Classical(More)
Bioequivalence studies are generally performed as crossover studies and, therefore, information on the intrasubject coefficient of variation is needed for sample size planning. Unfortunately, this information is usually not presented in publications on bioequivalence studies, and only the pooled inter- and intrasubject coefficient of variation for either(More)
Relative Bioavailability of Paracetamol as Suppositories Compared to Tablets. The relative bioavailability of paracetamol (CAS 103-90-2) in ben-u-ron 500 mg and ben-u-ron 1000 mg suppositories (test formulations) was compared with that of Benuron tablets 500 mg (reference product) in an open, intraindividual, 3-period-changeover-study in 18 healthy(More)
OBJECTIVE Hospitalized smokers are often highly motivated to quit and receptive to assistance. There are few published accounts of hospital-based smoking cessation programmes implemented outside of a trial setting, particularly outside North America. We describe the implementation and effectiveness of a dedicated smoking cessation service in Freiburg,(More)
AIMS Thioctic acid (TA), glibenclamide and acarbose are widely used to either alone or concomitantly treat patients suffering from noninsulin-dependent diabetes (NIDDM). This study systematically investigated drug-drug interactions between TA and glibenclamide and TA and acarbose. METHODS Fourteen male and 10 female healthy volunteers participated a(More)
Relative Bioavailability Studies on Paracetamol in Suppositories as Compared to Tablets. Relative bioavailabilities of 250 mg paracetamol (CAS 103-90-2) in ben-u-ron 125 mg and ben-u-ron 250 mg suppositories were determined in comparison with that of cut-in-half Benuron tablets 500 mg in an open intraindividual 3-period-changeover-study in 18 healthy(More)
BACKGROUND Previous studies revealed that surgical lung biopsy in usual interstitial pneumonia (UIP) patients is accompanied with higher morbidity and mortality. The aim of this retrospective analysis was to assess morbidity and mortality of patients with suspected UIP undergoing surgical lung biopsy. METHODS We conducted a retrospective study of 45(More)
Bioequivalence studies are usually performed as crossover studies and, therefore, information on the intrasubject coefficient of variation is needed for sample size planning.
