Precision and Bias of Target-Controlled Prolonged Propofol Infusion for General Anesthesia and Sedation in Neurosurgical Patients
2018
The aim of this study was to determine the relationship, precision, and bias of a propofol target-controlled infusion (TCI) system during prolonged infusion in neurosurgical patients. We retrospectively included patients undergoing general anesthesia for elective neurosurgical removal of brain tumors and postoperative sedation in the intensive care unit over a period of 3 months. TCI of propofol (Diprifusor - Marsh model) and remifentanil were used for general anesthesia and sedation. We compared propofol blood concentration (Cmeas) measured by liquid chromatography-mass spectroscopy with predicted concentrations (Cpred) by the TCI system at 40 minutes (T0), 2 hours (T1), and 4 hours (T2) a…
Effect of non-surgical periodontal treatment with or without doxycycline on the periodontium of type 1 diabetic patients
2005
Aim: The present investigation was performed to study how type 1 diabetics responded to non-surgical periodontal treatment with and without adjunctive doxycycline. Method: Sixty diabetic type 1 patients (mean age 35.3 +/- 9 years) with moderate-to-severe periodontal disease were selected and divided into two groups of 30 patients each. Both groups were sex and age matched and had similar amounts of periodontal destruction. Plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment levels (CAL) were recorded. Group 1 (30 patients) was treated with oral hygiene instruction, scaling and root planing, chlorhexidine rinses twice a day and doxycycline (100 mg/day for…
Efficacy of 3 toothbrush treatments on plaque removal in orthodontic patients assessed with digital plaque imaging: a randomized controlled trial.
2013
Good oral hygiene is a challenge for orthodontic patients because food readily becomes trapped around the brackets and under the archwires, and appliances are an obstruction to mechanical brushing. The purpose of this study was to compare plaque removal efficacy of 3 toothbrush treatments in orthodontic subjects.This was a replicate-use, single-brushing, 3-treatment, examiner-blind, randomized, 6-period crossover study with washout periods of approximately 24 hours between visits. Forty-six adolescent and young adult patients with fixed orthodontics from a university clinic in Germany were randomized, based on computer-generated randomization, to 1 of 3 treatments: (1) oscillating-rotating …
Effectiveness of a miswak extract-containing toothpaste on gingival inflammation: a randomized clinical trial.
2015
Objectives In this study, the efficacy of a miswak extract-containing toothpaste (Salvadora persica) on gingival inflammation was compared with that of a herbal and a conventional toothpaste. Methods Non-smoking outpatients with sulcus bleeding index (SBI) ≥25% and with periodontal pocket depths ≤3 mm were randomly selected and divided into three groups: M-group, miswak extract-containing toothpaste; P-group, herbal toothpaste; and C-group, conventional toothpaste. After instructing the patients to brush their teeth twice a day for 3 weeks with the assigned toothpaste using a flat-trimmed manual toothbrush, a thorough oral examination was performed by a calibrated examiner (EH). The primary…
Time course of adverse events most commonly associated with topiramate for migraine prevention
2007
The efficacy, safety and tolerability of topiramate has been demonstrated in three large multicenter, randomized, double-blind, placebo-controlled trials. To characterize the time course of adverse events (AEs) that led to treatment discontinuation in/=2% of patients who received topiramate 100 mg/day during three pivotal, multicenter, randomized, double-blind, placebo-controlled, and 26-week trials. The pooled population comprised all randomized patients who reported safety data during the double-blind phase (topiramate 100 mg/day, n = 386; placebo n = 372), which consisted of a 4-week titration period and a 22-week maintenance period. Incidence, time to onset, and cumulative mean rate of …
Preliminary organizational culture scale focused on artifacts
2006
In this preliminary study, an organizational culture scale was developed to assess cultural artifacts according to Schein´s typology (1985). It includes a set of cultural artifacts to measure the extent to which an organization is more or less traditional. A total of 249 managers from a range of different companies responded to the items. Preliminary analysis yielded a one-dimensional scale with 14 items with high internal consistency and homogeneity.
The effect of vibration therapy on neck myofascial trigger points: A randomized controlled pilot study
2020
[EN] Background: The purpose of this study was to evaluate the effect of low-frequency self-administered vibration therapy into myofascial trigger points in the upper trapezius and levator scapulae on patients with chronic non-specific neck pain. Methods: Twenty-eight patients with chronic non-specific neck pain were randomly assigned into a vibration group, receiving 10 self-applied sessions of vibration therapy in the upper trapezius and levator scapulae trigger points; or a control group, receiving no intervention. Self-reported neck pain and disability (Neck Disability Index) and pressure pain threshold were assessed at baseline and after the first, fifth and 10th treatment sessions. Fi…

Non-invasive vagus nerve stimulation (nVNS) for the preventive treatment of episodic migraine: The multicentre, double-blind, randomised, sham-contro…
2019
Introduction Non-invasive vagus nerve stimulation (nVNS; gammaCore®) has the potential to prevent migraine days in patients with migraine on the basis of mechanistic rationale and pilot clinical data. Methods This multicentre study included a 4-week run-in period, a 12-week double-blind period of randomised treatment with nVNS or sham, and a 24-week open-label period of nVNS. Patients were to administer two 120-second stimulations bilaterally to the neck three times daily (6–8 hours apart). Results Of 477 enrolled patients, 332 comprised the intent-to-treat (ITT) population. Mean reductions in migraine days per month (primary outcome) were 2.26 for nVNS (n = 165; baseline, 7.9 days) and 1.8…
Ranibizumab for Branch Retinal Vein Occlusion Associated Macular Edema Study (RABAMES): six-month results of a prospective randomized clinical trial
2014
Purpose To compare standard-of-care grid laser photocoagulation versus intravitreal ranibizumab (IVR) versus a combination of both in the treatment of chronic (>3 months) macular oedema secondary to branch retinal vein occlusion. Methods Prospective, randomized, multicentre clinical trial. Thirty patients with a best-corrected visual acuity (BCVA) between 20/320 and 20/40 were randomized 1:1:1 to receive grid laser or three monthly injections of 0.5 mg IVR or both followed by 3 months of observation. Results Mean change from baseline BCVA at month 6 was +2 letters [laser; 0.04 logMAR, 95% confidence interval (−0.17; 0.25)], +17 letters [IVR; 0.34 (0.19; 0.5)] and +6 letters [combination; 0.…
