A double-blind placebo-controlled dose-response trial of nebivolol, a cardioselective beta-blocking drug which also induces endothelium-dependent dilatation via nitric oxide, has been performed. Nebivolol reduced blood pressure (BP) in a dose dependent way, and was shown to be effective given once daily, without appreciable differences between peak and trough drug levels. There was no postural component to the BP fall.

Because reflux to a limited extent is physiologic, the determination of optimal thresholds to separate normal from abnormal reflux is mandatory. Esophageal pH was measured during 24 hours in 509 healthy thriving infants, aged 3 days to 1 year, using a glass microelectrode with an external reference electrode connected to a portable recorder.

In this study, data recorded with glass microelectrodes or antimony electrodes, both with external cutaneous Ag/AgCl reference electrodes, connected to two different recording devices are compared. Pearson correlation coefficients regarding the reflux index (% of the investigation time with a pH less than 4) ranged from poor to excellent (0.

Twenty four hour pH monitoring was performed using identical equipment on two consecutive days under similar conditions. Pearson correlation coefficients range from 0.

Esophageal pH monitoring data are influenced by numerous patient- and/or technical equipment-related factors. In this study, data obtained with 10 pH recording devices of two different companies and 10 pH glass-microelectrodes with an external reference electrode of one company, calibrated by different persons, were compared. Pearson correlation coefficients regarding the reflux index (the percentage of the investigation time with a pH less than 4) ranged from 0.

Almost 50% were women with vaginal candidosis; a dosage of 200 mg per day for three days appeared to be optimal for their treatment. Several treatment regimens were tested for pityriasis versicolor; the minimum total dose necessary for optimal results was 1 g.
