Filter by:The chief aim of this study is to evaluate the difference in tooth sensitivity after having used a gel containing nano - hydroxyapatite and potassium nitrate This randomized double-blind clinical study is designed to compare the efficacy in reducing dentin hypersensitivity of a toothpaste gel containing Nano-hydroxyapatite and potassium nitrate (Cavex Bite & White ExSense, Cavex Holland BV) with a fluoride-based gel toothpaste ( Colgate, Protection Caries, Palmolive SPA ). Specific objectives : To evaluate through standardized tests the dental sensitivity before and after the application of toothpastes; To compare the variations of dental sensitivity test and control groups. Safety: determination of adverse reactions, such as increased tooth pain and changes in the oral mucosa after application of the materials.
Rheumatoid arthritis (RA) is the most frequent form of chronic inflammatory rheumatism in adults. The erosive damage influences the functional prognosis in patients with RA. At present, there are no sufficiently sensitive and specific predictive markers of erosive damage.
Patients consulting in the Allergy Unit of the Arnaud de Villeneuve Hospital for whatever suspicion of allergy were asked to participate in the study. Besides a standard battery of respiratory allergens, native raw and cooked potato were tested by means of the prick to prick method, using a metal lancet.
Compare teeth sensitivity using bleaching protocol with different light intensities (Philips Zoom!™ White Speed whitening gel and lamp, Discus Dental, Inc., Culver City, CA, USA.) versus bleaching protocol with the same light intensity (Philips Zoom!™ Advanced Power whitening gel and lamp, Discus Dental, Inc., Culver City, CA, USA.).
This investigation examines the efficacy of a 35 minute computerized psychoeducation protocol in the reduction of elevated anxiety sensitivity cognitive concerns, a risk factor for the development and maintenance of various forms of psychopathology.
This study will evaluate the effectiveness of an experimental dentifrice containing stannous fluoride, an established dentine tubule occlusion technology, at reducing dentine hypersensitivity (DH) compared to a negative control dentifrice. The test and control dentifrices will be administered for a total of 8 weeks, with assessments (via evaporative air and tactile stimuli) at baseline, and after 4 and 8 weeks twice-daily use.
Today, we know that olfactogustatory alterations occur in cirrhotic patients before the liver transplant but no study has been conducted to show eventual disturbances after the transplantation able to explain modifications in eating behaviour. In parallel, the metabolic status, itself dependent on liver metabolism, influences food preferences and is modified after the transplantation as the liver recovers its ability to store glycogen, but is not able to inform the brain as the afferent nerve impulses have been suppressed. The innovative aspect of this project is to provide information on the importance of the liver in the regulation of energy homeostasis. The results of this study will improve our understanding of eating behaviour and olfactogustatory sensitivity and allow us to orient liver transplant patients towards appropriate diets.
For decades, it has been known that post-meal blood glucose concentrations were associated with the risk of T2D, which was reflected in early diagnostic guidelines. The oral glucose tolerance test (OGTT) has been used since at least 1923 and has remained the most common test for assessing glucose tolerance. Arterial blood (or arterialised blood using heated hand technique) is most appropriate for determining glucose tolerance and insulin sensitivity since this best represents the concentrations of metabolites and hormones that peripheral tissues are exposed to. It is essential to investigate whether venous blood (sometimes used during an OGTT) is representative of arterialised blood during an OGTT, and under different metabolic conditions. The investigators want to understand whether OGTT-derived insulin sensitivity indices differ from venous and arterialised blood; and 2) investigate whether metabolic status (i.e. rest vs lower-limb exercise) influences the difference between forearm venous and arterialised concentrations of glucose and insulin during an OGTT.
Data about aspirin desensitization for patients with coronary artery disease undergoing percutaneous coronary intervention are sparse. This is a prospective, multicenter, observational study including 7 italian centers, to assess safety and feasibility of a standard desensitization protocol in patients with aspirin sensitivity undergoing coronary angiography. Patients with history of aspirin sensitivity undergoing coronary angiography are prospectively enrolled.All patients underwent the desensitization procedure with six sequential doses of aspirin (1, 5, 10, 20, 40, and 100 mg) administered orally at predefined intervals, with the procedure lasting 5.5 hours.All patients are followed for desensitization procedure success, description of reactions due to the desensitization procedure, and in hospital major adverse cardiac events (MACE). All patients are also followed-up for 12 months in order to assess their long-term risk of MACE, compliance with ASA therapy, and late occurrence of side reactions due to ASA sensitivity.
The COBIOPHAD project targets the development of a highly sensitive, selective, and multiplexed diagnostic device to provide a quick and inexpensive in vitro test to address the most prevalent drug hypersensitivity to betalactams antibiotics, (BLCs). During a retrospective study, BLC structures involved in drug hypersensitivity will be identified from sera of allergic patients (versus controls) and coupled on the device. A prospective study will be performed for the recruitment of samples corresponding to patients with known IgE hypersensitivity to BLCs based on results from allergy tests and clinical history. Controls will include: non-allergic individuals with known tolerance to betalactams. The samples will be used for the validation of the COBIOPHAD device in real settings.
