Ablative Fractional Lasers to Treat Peri-orbital Rhytides

Ablative fractional lasers were introduced for treating facial rhytides in an attempt to achieve results comparable to traditional ablative resurfacing but with fewer side effects. However, there is conflicting evidence on how well this goal has generally been achieved as well as on the comparative value of fractional CO2 and Er:YAG lasers. The present study compares these modalities in a randomized controlled blinded split-face study design: 28 patients were enrolled and comp...

Inter-rater and intra-rater reliability will also be tested by comparing the assessment results of two different n...

Does Race Make a Difference in Obstructive Sleep Apnea?

Obstructive sleep apnea (OSA) is a sleep-related breathing disorder, often associated with a compromised upper airway space and an increase in upper airway collapsibility. The anatomical and functional abnormalities of the upper airway play an important role in the pathogenesis of OSA. It is hypothesized that there is racial variation in the craniofacial characteristics among OSA patients. However, inter-race comparisons based on previous studies can be problematic due to varia...

Intra-observer and Inter-observer Variability With Dynamic Contour Tonometry.

The aim of the protocol is to document intra-observer and inter-observer variability with dynamic contour tonometry, and will also test the theory that pulse amplitude, as measured by dynamic contour tonometry, is correlated with the difference in systolic and diastolic blood pressures.

Transcranial Magnetic Stimulation Study of Cortical Excitability as Marker of Antidepressant Response: EXCIPSY Study

Depression is a common issue but there is no marker of response to an antidepressant treatment.The measurement of variation of the cortical excitability in responders to a selective serotonin reuptake inhibitor (SSRI) (compared to no-responders) had never been done before. In the study of Robol et al. (2004) concerning the acute effects of citalopram on markers of cortical excitability, the authors have pointed out an increase on the cortical silent period (CSP) after administr...

Inter- and Intra-individual Variations in Metformin Pharmacokinetics - The Importance of Genes and Drug Interactions

The investigators aim to investigate the interindividual variation in metformin AUC in a large cohort of healthy volunteers after a single dose of metformin. Part 1 is driven by the hypothesis that metformin AUC and renal clearance exhibit significant interindividual variation. However this has never been documented in a large cohort of healthy volunteers. The investigators aim to investigate the potential interaction between codeine and metformin in the intestine. The hypothe...

One-Dimensional Mathematical Model-Based Automated Assessment of Fractional Flow Reserve

This study evaluates the diagnostic efficiency of an automated method of noninvasive assessment of the fractional reserve of coronary blood flow. Fractional flow reserve is estimated with a one-dimensional mathematical model constructed by means of an automated algorithm. Noninvasive method values are thereafter compared with invasive method values.

Fractional Microplasma Radiofrequency Technology for Non-hypertrophic Post-burn Scars in Asians: A Prospective Study of 95 Patients

A prospective study to evaluate the efficacy and safety of FMRT for treating non-hypertrophic post-burn scars in an Asian population.

Inter Individual Variation in Weight Loss Response to Exercise

The identification and characterization of individuals who vary in their response to exercise-induced weight loss is important. Weight loss in response to exercise is variable and it remains unknown who will succeed, why, and more importantly how to improve weight loss efficacy. This study will examine changes in behavioural, metabolic, physiological and biochemical variables in response to a 12 week supervised exercise programme and evaluate their association with weigh...

Fractional Flow Reserve in Italian Cath-labs

Italy is the European country with the minor penetration of FFR as compared to the number of percutaneous coronary intervention. Accordingly, the Società Italiana di Cardiologia Invasiva (SICI-GISE) conceived and promoted a prospective nationwide study to describe the patterns of the use of FFR in an unselected real-world population and to to assess the reasons, on clinical decision making, driving operators in the use or not of the FFR.

Efficiency of Fractional-Laser Resurfacing Followed by Topical Tacrolimus 0.03% Cream vs Tacrolimus Alone in Vitiligo

The aim of our clinical trial was to find out whether fractional CO₂ laser sessions in combination with application of daily topical tacrolimus 0.03% would enhance the action of the drug and pose as a possible combination treatment option for stable vitiligo lesions. We applied this combination treatment on one side of the body and compared the response to the response of the lesions on the other side of the body to daily topical tacrolimus 0.03% alone, which we used as contr...

Validation of a Subjective Rating Scale for Assessment of the Surgical Workspace in Laparoscopy

It is of great importance to obtain optimal surgical conditions for the surgeon in order to increase patient safety. The effect of different interventions on surgical conditions has been assessed by various surgeon-assessed rating scales. A 5-point surgical rating scale has previously been tested in a proof-of-concept trial - but not validated - during radical retropubic prostatectomy by asking different surgeons to evaluate the surgical workspace using video sequences. ...

Is a Reporting System for Gastritis or Duodenitis (Modified Lanza Scale) Reproducible?

The modified Lanza scale (Lanza FL, 1984) has been widely utilized to grade the degree of gastritis and duodenitis. However, the inter-rater or intra-rater reproducibility of this scale has never been validated. As a quality improvement program, it is important to study the reproducibility of the scale between different operators and the operators himself. Method: During upper endoscopic examinations, one investigator performed the procedure and the second investigator look ...

Figure-of-Eight Hand, Volumetric Measurements and Reliability in Clinic With Hand Injured Patients

This study determined the intra-rater and inter-rater reliability of the Figure-of-Eight method on healthy hands, and compared the figure-of-eight measurements to the gold standard volumetric measurements. Part B of the study conducted in a clinic, assessed the intra-rater reliability and inter-rater reliability on both hands of patients with hand injuries.

Variability of Daily Iodine Intake: The Effects of Intra- and Inter-individual Variability in Iodine Nutrition Studies

Iodine status in populations is assessed using urinary iodine concentration (UIC) measured in spot urine samples. The iodine intake is classified as deficient, sufficient, or excessive iodine based on the median UIC (mUIC). However, this approach has limitations, as it does not quantify the prevalence of individuals with habitually deficient or excess iodine intakes. The EAR cut-point method has the potential to quantify prevalence of iodine deficiency and excess. However, litt...

Regadenoson to Achieve Maximal Hyperemia for Fractional Flow Reserve in the Catheterization Lab

The purpose of this study is to determine if regadenoson is as safe and effective as adenosine when used in the cardiac catheterization lab during measurement of coronary flow reserve and fractional flow reserve. The study hypothesis is the assessment of Fractional Flow Reserve (FFR) in the catheterization lab can be performed with equivalent accuracy when hyperemia is induced with IV Regadenoson compared with IV Adenosine without compromising patient safety.

Comparison Between Contact Force Guided and Blinded Strategy on PV Isolation in AF Patients

Pulmonary vein (PV) isolation is very important in atrial fibrillation (AF) catheter ablation. PV reconnection is one of the main reasons in AF recurrence. Contact force-sensing catheter is a new catheter which has valuable tools to monitor and increase the efficacy of PV isolation. Previous paper reported the efficacy of contact force-sensing catheter on immediate PV isolation and outcome. However, there might be confounding factor as inter-individual variation. Therefore, we ...
