Filter by:A multicenter, open-label study to evaluate the sensitivity and specificity of inhaled methacholine in bronchial provocation test
The objective of this study is to determine the biological activity of Juniperus oxycedrus and Cupressus arizonica. allergen extracts in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
The objective of this study is to determine the biological activity of Quercus illex and Quercus robur allergen extracts in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
This pilot study trial will test the acceptability, feasibility, and usability of a brief enhanced anxiety sensitivity treatment to reduce anxiety sensitivity and functional impairment in Veterans.
An experimental study aims to investigate the efficacy of Nigella Sativa in children with house dust mite (HDM)-induced respiratory allergy receiving immunotherapy. This study observes symptom, medication, combine symptom-medication score, quality of life (QoL), skin prick test, IL-4, TGF-β, IL-10, IgG4 specific HDM, IgE Specific HDM, and IFN-γ as the outcome. This study will be done on 40 subjects (20 subjects in control group and 20 subjects in experimental group), in children diagnosed with house dust mite-induced respiratory allergy such as allergic rhinoconjunctivitis and/or asthma, with an age of 2 to 17 years old, receiving allergen specific immunotherapy, not having an autoimmune disease, malignancy, nor chronic respiratory infection at the beginning of study, and has an approval from their parents. In control group, subjects will receive allergen specific immunotherapy and standard pharmacotherapy for underlying diagnose. In experimental group, subjects will receive nigella sativa oil for 14 weeks, allergen specific immunotherapy, and standard pharmacotherapy for underlying diagnose. All subjects will observe for 14 weeks during build up phase of immunotherapy. They will be monitored regularly, since this study starts, at each week, and at the end of this study. The symptom, medication, and combine symptom-medication score will be calculated at every session of monitoring. Quality of life (QoL), skin prick test, IL-4, TGF-β, IL-10, IgG4 specific HDM, IgE Specific HDM, and IFN-γ will be collected at the beginning and the end of this study.
Photobiomodulation has been widely used as complementary treatment for dentin hypersensitivity, with reports of clinical success. However, the literature offers only one study in which photobiomodulation was used for the treatment of sensitivity in molars with molar incisor hypomineralization (MIH). The aim of the proposed study is to determine whether photobiomodulation enhances the results of treatment with glass ionomer sealant on molars with MIH that present sensitivity. Methods and analysis: The study involving 50 patients 6 to 12 years of age tha will be randomly allocated in two groups. Group 1 (control group) (n = 25): toothpaste with a concentration of fluoride, glass ionomer sealant and sham low-level laser (LLL) and Group 2 (n = 25): toothpaste with a concentration of fluoride, glass ionomer sealant and active low-level laser (LLL). The evaluations will involve MIH record, Simplified Oral Hygiene Index (OHI), Schiff Cold Air Sensitivity Scale (SCASS) and Visual analog scale (VAS) before the procedure. Immediately after the procedure hypersensitivity index (SCASS/VAS) will be register. Record of OHI and SCASS/VAS will be register 48 horas after and as well as 01 month after the procedure. It is expected that by the second consultation a decrease in sensitivity will be observed due to the treatments received in the two groups.
NOVAPAK is a sponge-like material made from materials found in shellfish. It is commonly used after nasal surgery or in nasal bleeding, as it promotes healing, decreases bleeding, and has antibacterial properties. Although NOVOPAK does not contain proteins or compounds known to be responsible for allergic reactions in people with a known allergy to shellfish, out of an abundance of caution, the manufacturer (Medtronic) has recommended avoidance in those with known shellfish allergy. There have been no reported allergic reactions in patients with shellfish allergy who were given chitosan bandages in emergencies (e.g. military applications). The study aims to investigate the safety of its use in patients with known shellfish allergy to improve healthcare quality and patient care support.
The prevalence of allergy to legumes is inscreasing, especially in children and for some of these legumes, little is known and there are not included in the list of priority allergen. The overall goal of this study is to improve knowledge about fenugreek allergy. The principal aim is to evaluate the prevalence of allergy to fenugreek confirmed by a positive oral food challenge in children sensitized to fenugreek. The secondary objectives are to describe the case of allergy to fenugreek (co-allergies, severity, age..), to evaluate diagnostic values of skin prick-tests and specific IgE and to compare the molecular profile of specific IgE to peanut between sensitization to fenugreek without allergy and sensitization with a confirmed allergy
The investigators hypothesize gold is inert and thereby there is no pure-gold allergy. The primary aim of this study is to measure the prevalence of allergy to metallic pure gold microparticles and allergy to GSTS.
