ABSTRACT

Mast cells and eosinophils are commonly found, expectedly or unexpectedly, in human tissue biopsies. Although the clinical significance of their presence, absence, quantity, and quality continues to be investigated in homeostasis and disease, there are currently gaps in knowledge related to what constitutes quantitatively relevant increases in mast cell and eosinophil number in tissue specimens for several clinical conditions. Diagnostically relevant thresholds of mast cell and eosinophil numbers have been proposed and generally accepted by the medical community for a few conditions, such as systemic mastocytosis and eosinophilic esophagitis. However, for other mast cell- and eosinophil-associated disorders, broad discrepancies remain regarding diagnostic thresholds and how samples are processed, routinely and/or specially stained, and interpreted and/or reported by pathologists. These discrepancies can obfuscate or delay a patient's correct diagnosis. Therefore, a work group was assembled to review the literature and develop a standardized consensus for assessing the presence of mast cells and eosinophils for a spectrum of clinical conditions, including systemic mastocytosis and cutaneous mastocytosis, mast cell activation syndrome, eosinophilic esophagitis, eosinophilic gastritis/enteritis, and hypereosinophilia/hypereosinophilic syndrome. The intent of this work group is to build a consensus among pathology, allergy, dermatology, hematology/oncology, and gastroenterology stakeholders for qualitatively and quantitatively assessing mast cells and eosinophils in skin, gastrointestinal, and bone marrow pathologic specimens for the benefit of clinical practice and patients.

ABSTRACT

Exercise-induced bronchoconstriction, otherwise known as exercise-induced bronchoconstriction with asthma or without asthma, is an acute airway narrowing that occurs as a result of exercise and can occur in patients with asthma. A panel of members from the American Academy of Allergy, Asthma & Immunology Sports, Exercise, & Fitness Committee reviewed the diagnosis and management of exercise-induced bronchoconstriction in athletes of all skill levels including recreational athletes, high school and college athletes, and professional athletes. A special emphasis was placed on the recommendations and regulations set forth by professional athletic organizations after a detailed review of their collective bargaining agreements, substance abuse policies, antidoping program manuals, and the World Anti-Doping Agency antidoping code. The recommendations in this review are based on currently available evidence in addition to providing guidance for athletes of all skill levels as well as their treating physicians to better understand which pharmaceutical and nonpharmaceutical management options are appropriate as well as which medications are permitted or prohibited, and the proper documentation required to remain compliant.

ABSTRACT

Asthma affects approximately 300 million people worldwide and approximately 7.5% of adults in the United States. Asthma is characterized by inflammation of the airways, variable airflow obstruction, and bronchial hyperresponsiveness. The diagnosis of asthma is a clinical one with the history and physical examination being significant, but objective measures, such as pulmonary function testing, can be used to aid in the diagnosis. There are multiple associated comorbidities with asthma, including rhinitis, sinusitis, gastroesophageal reflux disease, obstructive sleep apnea, and depression. There is often an allergic component of asthma, and patient education is vital.

ABSTRACT

Provider health and wellness is a significant issue and can impact patient care, including patient satisfaction, quality of care, medical errors, malpractice risk, as well as provider and office staff turnover and early retirement. Health and wellness encompasses various areas including burnout, depression, divorce, and suicide and affects providers of all specialties and at all levels of training. Providers deal with many everyday stresses, including electronic health records, office politics, insurance and billing issues, dissatisfied patients, and their own personal and family issues. Approximately half of all physicians suffer from burnout, and the rate of burnout among physicians of all specialties is increasing. An important first step in dealing with burnout is recognition and then seeking assistance. Strategies to prevent and treat burnout include increasing provider resiliency as well as implementing practical changes in the everyday practice of medicine. There is currently very little data regarding health and wellness specifically in the field of allergy and immunology, and studies are necessary to determine the prevalence of burnout and related issues in this field. Many medical specialties as well as state and national medical associations have health and wellness committees and other resources, which are essential for providers. Health and wellness programs should be introduced early in a provider's training and continued throughout a provider's career.

ABSTRACT

Loeffler endocarditis is a complication of hypereosinophilic syndrome resulting from eosinophilic infiltration of heart tissue. We report a case of Loeffler endocarditis in which three-dimensional transthoracic and transesophageal echocardiography provided additional information to what was found by two-dimensional transthoracic echocardiography alone. Our case illustrates the usefulness of combined two- and three-dimensional echocardiography in the assessment of Loeffler endocarditis. In addition, a summary of the features of hypereosinophilic syndrome and Loeffler endocarditis is provided in tabular form.

ABSTRACT

Partial DiGeorge syndrome (pDGS) is an inherited primary immunodeficiency syndrome (incidence, 1:3000 live births) primarily affecting cellular immune function; partial, infers thymic hypoplasia with detectable circulating T-lymphocytes and adequate function. No guidelines exist regarding the recommendations for use of live viral vaccines (LVVs) in this extensive population of pediatric patients. We reviewed the experience with live viral vaccines in our cohort of patients with pDGS. Of 53 patients, 25 (47%) had received a live viral vaccine. No significant adverse events were recorded in association with administration of live viral vaccines. There was no statistically significant difference between cellular immune function at initial presentation between those patients that received live viral vaccines and those that did not. Adequate cellular immune function was documented for 15 of the 25 LVV recipients at the time of vaccine administration without significant change from baseline. These observations suggest that live viral vaccines appear safe in patients with pDGS and stable immune function.
