IJERPH, Vol. 16, Pages 3828: Assessment of Respiratory Health Symptoms and Asthma in Children near a Drying Saline Lake International Journal of Environmental Research and Public Health doi: 10.3390/ijerph16203828 Authors: Shohreh F. Farzan Mitiasoa Razafy Sandrah P. Eckel Luis Olmedo Esther Bejarano Jill E. Johnston Residents of the Imperial Valley, a rural, agricultural border region in California, have raised concerns over high rates of pediatric asthma symptoms. There is an urgent need to understand the influences and predictors of children’s respiratory health in Imperial Valley. We assessed the impacts of sociodemographic, lifestyle, and household factors on children’s respiratory health and asthma prevalence by administering a survey to parents of elementary school children (n = 357) in northern Imperial Valley. We observed an overall asthma prevalence of 22.4% and respiratory symptoms and allergies were widely reported, including wheezing (35.3%), allergies (36.1%), bronchitic symptoms (28.6%), and dry cough (33.3%). Asthmatics were significantly more likely to report respiratory symptoms, but high rates of wheezing, allergies, and dry cough were observed among nonasthmatics, suggesting the possibility for underdiagnosis of respiratory impairment in our school-age population. Having an asthmatic mother and exposure to environmental tobacco smoke were also associated with greater odds of asthma. Our findings provide evidence to sup...
A boy with chronic cough, recurrent respiratory infections, and poor growth, but normal serum IgG, IgM, and IgA was diagnosed with a leaky phenotype of XLA. When there is clinical suspicion for possible B-cell deficiency, obtaining serum immunoglobulin levels alone may not be sufficient.
Prevalence and characteristics of chronic cough (CC) are poorly understood.
Cough variant asthma (CVA) is a type of asthma in which the main symptom is a dry, non-productive chronic cough (CC) in the absence of wheezing or shortness of breath (Corrao WM. Allergy Asthma Proc. 2018; 39: 466). The condition is frequently underdiagnosed, since baseline spirometric values are usually normal. Since airway inflammation is the basis of CVA, fractional exhaled nitric oxide (FeNO) is often used for patient evaluation but is still open to question. We aimed to explore the value of FeNO measurements in diagnosing patients with CC suspected to have CVA.
A commonly under recognized etiology of chronic cough is expiratory central airway collapse (ECAC). We implemented a forced expiratory computed tomography (CT) of the chest to evaluate for ECAC in chronic cough patients.
Loeffler syndrome, is a rare pulmonary manifestation of helminth infestation occurring during the pulmonary phase of the larval cycle. Respiratory symptoms, including cough, dyspnea, fever, and wheezing, in addition to skin, gastrointestinal and nonspecific symptoms can also be present. Helminths most commonly involved include Strongyloides, Ascaris, Ancylostoma and Necator.
A patient with progressive shortness of breath, dry cough, wheezing, tightness of the chest, may mimic uncontrolled asthma. A diagnosis of unsuspected cause such as mediastinal lymphoma might be delayed if a chest X-ray is not done.
Most cough/cold preparations contain sympathomimetic decongestants; many contain sedating antihistamines. Adverse effects, including death in children under 2, primarily from decongestants, but also from sedating antihistamines and dextromethorphan prompted FDA to recommend OTC cough and cold products not be used in this group. This, combined with manufacturer withdrawal under age 4, has created a cough and cold market void for young children in the US. Also, decongestant adverse effects in adults, including increased blood pressure, irregular heartbeat, and chest tightness resulted in contraindication in heart disease, hi...
Sluder ’s neuralgia (also known as sphenopalatine neuralgia) consists of neuralgic, sensory and gustatory manifestations attributed to irritation of sphenopalatine ganglion, usually from infection, deformity or scarring. Pain is associated with nasal and/or sinus congestion, swelling or erythema of nasal mucosa, tearing and facial erythema. Medical therapy for sinus decongestion can usually alleviate symptoms.
AbstractPurpose of ReviewFarmers are routinely exposed to organic dusts and aeroallergens that can have adverse respiratory health effects including asthma. Horses are farm-reared large animals with similar exposures and can develop equine asthma syndrome (EAS). This review aims to compare the etiology, pathophysiology, and immunology of asthma in horses compared to farmers and highlights the horse as a potential translational animal model for organic dust-induced asthma in humans.Recent FindingsSevere EAS shares many clinical and pathological features with various phenotypes of human asthma including allergic, non-allergi...
This study aimed to explore the age and sex distribution as well as their relationship with cough reflex sensitivity to capsaicin in Chinese chronic cough patients. METHODS: We analyzed the demographic features of 1,882 consecutive chronic cough patients who attended our cough clinic in Guangzhou, China. Cough sensitivity to capsaicin, which was defined as the lowest concentration of capsaicin causing 5 coughs or more (C5), was measured in 539 of the 1,882 patients and 68 healthy volunteers. RESULTS: The mean age of the patients was 43.0 ± 13.7 years and patients aged
