Filter by:The true prevalence of drug allergy in patients with a history of beta-lactam hypersensitivity will be determined by using commercially available standard skin test reagents and the diagnostic agents available in Thailand. We hypothesize that only minority of patients with such a history are truly allergic.
1. Objectives 1. to verify effect of Korean red ginseng on cold hypersensitivity of hands and feet in women 2. to establish scientific evidence for the use of Korean red ginseng by investigating changes of infrared thermography 2. Hypothesis The hypothesis is that Korean red ginseng will reduce cold hypersensitivity of hands and feet more effectively than placebo after 8 weeks administration of interventions- Korean red ginseng or the placebo.
The aim of the study is to determine safety, tolerability and feasibility of unilateral and bilateral carotid body excision in patients with systolic heart failure and peripheral chemoreceptor hypersensitivity.
Patients with chronic constipation due to food hypersensitivity (FH) had an elevated anal sphincter resting pressure. No studies have investigated a possible role of FH in anal fissures (AF). We aim to evaluate the effectiveness of a diet in curing AF and the clinical effects of a double-blind placebo controlled (DBPC) challenge with cow's milk protein or wheat.
The purpose of this study is to determine growth and protein status of infants with cow's milk protein allergy and treated with a newly innovated amino acid formula compared to those with a commercial amino acid formula.
This study evaluates the diagnostic efficacy of CAP System (capsulated hydrophilic carrier polymer) for recombinant tropomyosin from shrimp extract in discriminating between subjects allergic to shrimp with CAP positive subjects allergic to mites, crustaceans asymptomatic but with a positive CAP to shrimp, to identify those at greatest risk of food reactions.
There has been an increase in asthma and allergic disease prevalence, especially in children. Given the high prevalence, and the associated high disease burden and costs, there is an urgent need to identify effective strategies for the primary prevention of asthma and allergy. A systematic review of the literature has found strong supportive epidemiological evidence of a protective role for the Mediterranean Diet (MD). The investigators aim is to undertake a pilot trial in a sample of pregnant women to establish recruitment, retention, a measurable change to a dietary intervention encouraging greater adherence to a MD during pregnancy, and acceptability of the dietary advice and diet modifications. This pilot study will be a 2-arm randomised controlled trial (RCT) in a sample population of around 50 Scottish pregnant women. This work ultimately aims to contribute to improving health outcomes through seeking to reduce the incidence of asthma and allergic problems. This pilot trial will prove invaluable in informing the subsequent planned definitive parallel group RCT.
Otherwise healthy infants (1-12 months of age at the diagnosis) with CMA were prospectively evaluated. Patients with cow's milk protein-induced anaphylaxis, eosinophilic disorders of the gastrointestinal tract, and food protein induced enterocolitic syndrome were excluded. A food challenge was performed 6 and 12 months after the diagnosis to assess clinical tolerance acquisition. Main demographic and clinical characteristics were collected for each patient.
This study aimed to validate new recipes for cow's milk, hen's egg, soy, cod and wheat, to be used in blinded low-dose food challenges.
Eosinophilic esophagitis is characterized by an eosinophilic infiltration of the esophagus. It presents clinically with a variety of symptoms including dysphagia, emesis, and food impaction. Although the underlying mechanism is different, gastroesophageal reflux can present with similar clinical findings but can be distinguished from eosinophilic esophagitis by the number of eosinophils present on esophageal biopsy. In children, food allergies play a role in exacerbating eosinophilic esophagitis, but the role of food allergies in adults is uncertain. In this study, we aim to determine the prevalence of food allergies in a cohort of adults with eosinophilic esophagitis.
