Who diagnoses and treats nasal and ocular allergies in the US? Survey shows some surprises

Allergic rhinoconjunctivitis is managed by a number of health care professional specialties, whose practice styles may vary. This study included telephone surveys of randomly selected patients and health care professionals in the United States in 2012 (2,700 patients and 500 practitioners in 7 specialties).

Adult respondents to the patient survey reported that their allergies had been diagnosed most often by:

- physicians in family practice (46%)
- allergists/immunologists (17%)
- otolaryngologists, ENT (11%).

Children's allergies had been diagnosed most often by pediatricians (41%) and family practitioners (22%).

Most respondents with conditions diagnosed by an allergist/immunologist (95%) or otolaryngologist (63%) had been given an allergy test, but the test was not given to most patients with conditions diagnosed by family practitioners (61%) or pediatricians (65%).

Most patients (76%) were treating their allergies with over-the-counter medications, and 53% were taking prescription medications.

Allergen immunotherapy was being used by 33% (adult) or 28% (child) patients of allergist/immunologists, 25% (adult) or 24% (child) patients of otolaryngologists, and 8% and 10% of patients of family practitioners and pediatricians, respectively.

Game App For Asthma Education: Wellapets Virtual Pet

The Wellapets app has a fire breathing dragon. The pet is part of a video game that aims to help children with asthma.

When playing ‘Wellapets’ children must give their pet dragon a maintenance inhaler twice a day, just like many of them have to do in real-life. The game also aims to teach them to recognize symptoms and avoid asthma triggers like dust and smoke.

If the free asthma app is a success, the developers are looking at other games geared toward food allergies, diabetes, and childhood obesity.

The game looks like fun, but I'm not sure if the patients learn many useful skills, as the educational part is not really front and center, and that's by design. One of the founders said: "We initially made the mistake of building a game around educational objectives, rather than weaving educational objectives into a game, but through several rounds of testing and collaboration with industry veterans, we arrived at a more cohesive design." See for yourself how it all works in the video below:

Small airway involvement is present in all stages of asthmatic disease despite been referred to as 'silent zone'

This review provides an update on the importance of the peripheral, small airways in asthma. As the small airways account for less than 10% of total airway resistance, thus having little impact on standard lung function measures such as forced expiratory volume and peak flow, they have been referred to as the 'silent zone'.

Small airway involvement is present in all stages of asthmatic disease, and is related to important clinical phenotypes such:

- nocturnal asthma
- exercise-induced asthma
- difficult-to-control asthma
- patients with the risk of repeated asthma exacerbations

Uncontrolled small airway inflammation is related to airway remodeling and progression of the disease, with a more rapid decline in the lung function.

In order to control the disease, we need to target small airway inflammation, which is difficult to reach by standard inhaled medications. A better understanding of the role small airways are playing in asthma shows that the 'silent zone' is not silent at all.

Uvular Angioedema Due to ACE Inhibitor - NEJM

Angioedema is a swelling that is similar to hives, but the swelling is under the skin instead of on the surface.

In this NEJM case report, treatment with 6.25 mg of captopril was started 6 hours after cardiac stent placement, and 30 minutes after administration the patient reported difficulty swallowing and throat pain. The uvula was markedly edematous and erythematous:



Uvular angioedema, or Quincke's disease, was diagnosed, and treatment with antihistamines and glucocorticoids was started. Improvement was rapid, and the edema completely resolved within 24 hours.

Isolated uvular angioedema is usually caused by an immediate (type I) hypersensitivity reaction. Mast-cell degranulation can occur after exposure to an immunologic or nonimmunologic stimulant, such as a drug, as was the case in this patient.

Angiotensin-converting–enzyme (ACE) inhibitors can cause isolated uvular angioedema, and although this response to ACE inhibitors is uncommon, it is important to be aware of it, since it can lead to obstructive respiratory distress.
