Filter by:The Pain Sensitivity Questionnaire (PSQ) is a tool created in 2009 by Dr. R. Ruscheweyh in Germany. It aims at identifying the natural sensitivity to pain, through a set of 17 simple questions. These questions simulate daily life situations likely to induce pain of various intensities. The internal validity of the tool had been demonstrated both for the original version in German, and then for its English version. The external validity had also been demonstrated by correlation to real nociceptive stimulations applied to healthy volunteers (German version), and to patients before surgery (English version). A French validation of the questionnaire is needed, in order to integrate it in pain research programs in French-speaking countries.
The investigators surveyed the prevalence of animal allergy and sensitization to animal allergen among participants in international symposium of Korean association for laboratory science (laboratory animal researchers) and companion animal exhibition (pet owner and pet-related industry workers).
A new male-specific dog-allergen-component has been found (Can f 5) which indicates possible differences in allergic reactions to male and female dogs. This has not yet been tested in real life. The aim is to test if sensitization only to the male-dog specific allergen-component, Can f 5, results in a positive skin prick test (SPT) to male dog extract and not female dog extract. In addition, the investigators want to investigate if allergic symptoms only occur when exposed to the male dog extract by conjunctival provocation.
Oxytocin (OT) is a neuropeptide that acts as a neurotransmitter and neuromodulator in the brain. Previous studies have shown that intranasal administration of OT improves social cognition and behavior (e.g. emotion recognition). In the current study, we want to gain more insight into the underlying mechanisms by which OT influences emotion recognition. More specifically, we will investigate whether intranasal administration of OT enhances the salience of social (compared to non-social) information and whether it increases the neural sensitivity for subtle socio-emotional cues, by recording scalp electroencephalography (EEG) during Fast Periodic Visual Stimulation (FPVS).
The investigators designed a randomized controlled trial to evaluate whether perioperative Vaginal preparation is superior to no Vaginal preparation in decreasing post CS endometritis. Since CS is performed in about 30% of all births and infection complicates 6-11% of all CS reducing the rate of this post CS complication can have a major impact not only on the hospital occupancy and costs but also on the new mother experience and ability to face the challenge that awaits for her with her newborn. In this study patients will be randomly assigned into two groups. The experiment group will not undergo any vaginal preparation. The control will undergo perioperative vaginal preparation with antiseptic soap followed by chlorohexidine-alcohol Both groups will be checked for cervical dilation with sterile gloves before surgery. Primary outcome - signs of endometritis (e.g. erythema around surgical scar, discharge or pain). Patients will be followed daily until discharge. A blood count will be drewn before discharge to rule out signs of infection. Patients will be contacted 6 weeks after surgery by telephone to inquire about any signs of infection, Emergency Room visits or ambulatory visits to the doctor due to endometritis. The participants will be asked if they had positive skin culture or other wound complications such as cellulitis, seroma or scar separation. The investigators estimated that 1040 patients will have to enroll into the study, 520 in each group in order to have 80% power to detect 50% difference in the endometritis rates between the two groups with a two tailed α level of 0.05. The data analysis was conducted according to the per-protocol principle.
In this Project we will monitor the symptoms of cat allergic participants who live together with a cat which is immunized with FEL-CMV using the novel symptom recording method "HypoScore", a General weekly symptom score, and a skin prick test before and after immunization of the cat. This project may enable us to determine if the scoring System and the tests are able to detect a difference in participant symptoms before and after immunization of the cats.
Patients with type-1 diabetes are more susceptible to motility-related upper gastrointestinal symptoms. Dietary interventions are one of the treatment pillars for these symptoms. Many gastrointestinal conditions other than celiac disease, are being increasingly treated with gluten-free diet (GFD). The role of GFD in non-celiac type-1 diabetic patients with dyspepsia-like symptoms has not been assessed before. In this study, type 1 diabetes patients with concomitant upper gastrointestinal symptoms will be asked to follow a 1-month GFD to assess changes in upper gastrointestinal symptoms and gastroduodenal motility before and after the dietary intervention.
The aim of this clinical study is to evaluate the efficacy and dental sensitivity associated with Combined Bleaching Technique (in-office + at-home) varying in-office bleaching application under two different time protocols, and dentifrice containing arginine 8% and carbonate calcium use. One hundred eight participants who meet the study inclusion criteria will be selected. The desensitizing agent used will be a dentifrice containing 8% arginine and calcium carbonate. In each evaluation will be determined: tooth sensitivity and color. The data collected will be submitted to the factorial statistical analysis for evaluation of color and chi-square test for tooth sensitivity (α = 5%).
The Purpose of this trial is to investigate the efficacy and safety of Ojeok-san(OJS) on Korean Patients With Cold Hypersensitivity in the Hands
This study aims to evaluate the longevity and efficacy of two products potassium oxalate-basedin two concentrations, 10% and 5%, by triple randomized blind clinical trial (split-mouth) . The desensitization approach (single agent) and the long-term effectiveness (baseline, 1 week, 2 weeks, 3 weeks). Data will be collected, tabulated and submitted to statistical analysis.
