The history of medicine includes many errors. Some persisted for decades and caused great harm. Several are highlighted in this article, including the mythical thymic diseases: thymic asthma and status thymicolymphaticus. Some medical mistakes, such as the diet-heart hypothesis of Ancel Keys, continue to cause harm. To avoid future errors and their associated harm, I suggest a cultural shift encouraging professional humility and greater questioning of medical dogma. Medical education focused on teaching students this history may help with this cultural shift...

Background. Asthma results in significant pediatric hospitalizations in the inner city. Many asthmatic children were admitted to our hospital as a result of lack of medications or medical supplies that had been previously prescribed ("ran out," "broken," or "lost"). Objective. To identify the incidence of children admitted for asthma because of lack of prescribed medications/supplies and to assess risk factors for poor adherence between groups. Methods. This was a prospective chart review of 200 asthmatic children admitted to Children's Hospital of Michigan, Detroit...

BACKGROUND: Epithelial barrier dysfunction is a central feature in the pathogenesis of allergic disease. Epithelial-to-mesenchymal transition (EMT) has been proposed as one mechanism afflicting barrier in asthma. However, genes and pathways involved in aberrant epithelial-mesenchymal signaling, and their relationship to asthma severity, are poorly understood. METHODS: We used unbiased gene network analysis to evaluate functional convergence in epithelial gene expression signatures across multiple public access transcriptomics datasets of human asthma, followed by text mining to evaluate functional marker relevance of discovered genes...

BACKGROUND: The Asthma Impact on Quality of Life Scale (A-IQOLS) assesses the negative effect of asthma on quality of life (QoL) from the patient's perspective, using dimensions of Flanagan's Quality of Life Scale (QOLS), a measure of current QoL. OBJECTIVES: To determine and compare the psychometric properties of the A-IQOLS and QOLS, including their sensitivities to differences and changes in asthma status. METHODS: In a test-retest design (3-5 week interval), adults with persistent asthma underwent spirometry and were administered the A-IQOLS, other asthma outcome measures (ACT, ASUI, Marks and Juniper AQLQs), and QOLS...

Recent studies have shown that approximately 70% of patients with severe atopic dermatitis (AD) develop asthma. Development of AD in infancy and subsequent other atopic diseases such as asthma in childhood is referred to as atopic march. However, a causal link between the diseases of atopic march has remained largely unaddressed, possibly due to lack of a proper animal model. Recently, we developed an AD rat model showing chronically relapsing dermatitis and scratching behaviors induced by neonatal capsaicin treatment...

To determine the prevalence of human rhinovirus (HRV) infection in children with acute asthma exacerbations, investigation of HRV viral load and severity of asthma exacerbations is also required. Nasopharyngeal aspirates and swabs were collected and assessed for respiratory viruses. HRV-positive samples were sequenced to identify types and determine viral load. Outpatients with asthma exacerbations underwent follow-up evaluations, their swabs were collected and clinical outcomes were recorded at their next clinic visit 4 weeks later...

Omalizumab is frequently used as add-on treatment to inhaled corticosteroids (ICS) and long-acting β2-agonists in patients with suboptimal control of severe asthma. Patients with severe asthma will typically require chronic treatment, although due to the limited amount of data available there are still some concerns about the safety and efficacy of long-term therapy with omalizumab. Herein, in an extension of a previous 4-year study, we report disease-related outcomes of 8 patients with severe persistent allergic asthma who have been followed for a total of 9 years in a real-life setting...

We present a case that highlights the difficulties with diagnosis and the dangers of occupational allergic sinusitis and asthma left unrecognized. We describe the case history of a man who experienced work-related symptoms 1 year after beginning work as a cheesemaker at a creamery, and whose respiratory symptoms progressively worsened over 16 years before an occupational cause of his asthma was identified. His initial discrete episodes of sinusitis and acute bronchitis evolved into persistent asthma of increasing severity with exacerbations requiring repeated emergency room treatment...

Bernard Yu-Hor Thong
Allergic conjunctivitis (AC), which may be acute or chronic, is associated with rhinitis in 30%-70% of affected individuals, hence the term allergic rhinoconjunctivitis (AR/C). Seasonal and perennial AC is generally milder than the more chronic and persistent atopic and vernal keratoconjunctivitis. Natural allergens like house dust mites (HDM), temperate and subtropical grass and tree pollen are important triggers that drive allergic inflammation in AC in the Asia-Pacific region. Climate change, environmental tobacco smoke, pollutants derived from fuel combustion, Asian dust storms originating from central/north Asia and phthalates may also exacerbate AR/C...

Dysbiosis of the microbiome on the airway mucosa leads to the development of chronic inflammatory and allergic disorders. The aim of this study was to consider the potential diagnostic criteria for allergic fungal rhinosinusitis (AFRS) and nonallergic fungal rhinosinusitis (FRS), and the role of fungal presence in an environment for the development of AFRS. In this study, 136 patients were divided into two groups: patients with positive specific immunoglobulin E (sIgE) and fungal finding (AFRS group), and patients with negative sIgE and positive fungal finding (FRS group)...

INTRODUCTION: The significance of oxidative stress in pathogenesis of childhood asthma was recognized, but its role in the clinical manifestations of disease is still unclear. MATERIALS AND METHODS: The study was conducted in 96 asthmatic children. The urinary biomarker of oxidative stress, 8-oxo-7,8-dihydro-2-deoxyguanosine (8-oxodG/creatinine) was determined by using HPLC-MS/MS. ELISA was performed to measure myeloperoxidase (MPO) and Cu,Zn- superoxide dismutase (Cu,Zn-SOD) in serum...

CONTEXT: Asthma is a chronic inflammatory disorder of the airway with involvement of various cellular populations and release of many inflammatory mediators. Eosinophils and serum immunoglobulin E (IgE) are considered a good marker of airway inflammation in asthma. The correlation of clinical assessment with various markers of airway inflammation in asthma is not well established in the Indian population. AIMS: This study aims to study the correlation of serum IgE, sputum eosinophil count, and peripheral eosinophil count with clinical severity of Asthma...
