Fractional exhaled nitric oxide (FeNO) has been suggested as a non-invasive biomarker of airway inflammation, which is increased in atopic subjects. Whether sensitization to particular allergens is a predictive factor for increased FeNO levels is not yet fully understood. We conducted a retrospective cross-sectional study. From October to December in 2015, the medical documents of 127 mild, steroid-naive asthmatic children and 34 healthy age-matched children were enrolled in this study. The results of the FeNO measurements, skin prick test, and the spirometry were collected for analysis...

Cow's milk allergy (CMA) is the most frequent food allergy in children and oral immunotherapy (OIT) is a promising approach for treatment of patients. The most challenging cases are anaphylactic with coexisting asthma and proposing safe protocols is crucial especially in high risk groups. Considering that CMA varies among patients, an individualized OIT protocol would be beneficial to achieve a safer and more efficient method of desensitization. 18 children more than 3 years of age with IgE-mediated CMA were enrolled...

Mechanisms of natural selection can be identified using experimental approaches. However, such experiments often yield non-significant effects and imprecise estimates of selection due to low power and small sample sizes. Combining results from multiple experimental studies might produce an aggregate estimate of selection that is more revealing than individual studies. For example, bony pelvic armor varies conspicuously among stickleback populations, and predation by vertebrate and insect predators has been hypothesized to be the main driver of this variation...

BACKGROUND: Rhinoconjunctivitis is a global health problem and one of the most common chronic conditions in children. Development of rhinoconjunctivitis depends on both genetic and environmental factors. Many studies have investigated rhinoconjunctivitis, but only few studies have evaluated the risk factors for non-allergic rhinoconjunctivitis in children finding family history of atopic diseases and gender to be of importance. The aim of this study was to investigate possible risk factors in early life for rhinoconjunctivitis, allergic as well as non-allergic, in adolescence...

BACKGROUND: The major trigger of asthma exacerbations is infection with a respiratory virus, most commonly rhinovirus. Type 2 inflammation is known to be associated with an increased risk of exacerbations in general. Whether type 2 inflammation at baseline increases the risk of future virus-induced exacerbations is unknown. OBJECTIVE: To assess whether type 2 inflammation is associated with an increased risk of virus-induced exacerbations of asthma. METHODS: Stable asthmatics had spirometry, skin prick test, measurement of FeNO and sputum induced for differential cell counts...

BACKGROUND: Identification of asthma phenotypes enables a better understanding and management of this heterogeneous disease. Studies have reported associations between human leukocyte antigens (HLA) and asthma in different populations, but the results have been inconclusive and they have rarely considered the distinct disease phenotypes. Our objective was to characterize allergic and nonallergic asthma phenotypes and evaluate possible associations with the HLA system. METHODS: A total of 109 patients with asthma were prospectively followed during 2 years...

OBJECTIVE: Self-reported penicillin allergy is common among patients attending the ED, but is a poor predictor of true immunoglobulin E-mediated hypersensitivity to penicillin. We hypothesise that with a combination of skin testing and drug provocation testing, selected patients can be safely de-labelled of their allergy. METHODS: This prospective study enrolled a sample of patients presenting to an urban academic ED between 2011 and 2016 with a self-reported allergy to penicillin...

Existing Point-of-care tests (POCT) to help identify infection-related causes of illness can complement diagnostic and disposition decisions in children attending emergency departments.(1) Evidence-based clinical algorithms can integrate such POCT to aid in the admission and discharge decision process. Paediatric studies validating these tools are scarce, with very few studies conducted in UK centres.(2-5) POCT can be based on host infection markers (e.g. finger prick tests for C-reactive protein (CRP) to help decide if the patient has a bacterial or viral infection) or pathogen detection tests (e...

Insulin allergy has been uncommon since the introduction of human recombinant insulin preparations; the prevalence is 2.4%. Insulin injection could elicit immediate reactions, which are usually induced by an IgE-mediated mechanism, within the first hour after drug administration. In the present study, we describe the case of a child who experienced immediate urticaria after long-acting insulin injection. A 9-year-old girl affected by type I diabetes mellitus referred a history of three episodes of urticaria 30 min after insulin subcutaneous injection...

Allergy tests are routinely performed in most hospitals everyday. However, measuring the outcomes of these tests is still a very laborious manual task. Current methods and systems lack of precision and repeatability. This work presents a novel mechatronic system that is able to scan a patient's entire arm and provide allergists with precise measures of wheals for diagnosis. The device is based on 3D laser technology and specific algorithms have been developed to process the information gathered. This system aims to automate the reading of skin prick tests and make gains in speed, accuracy and reliability...
