When It's Not A Sunburn But A Sun Allergy
As it gets warmer and people start spending more time outside, I have more and more patients coming into my office and complaining of a “sun allergy.” A sun allergy is really a layman’s term, which refers to a number of conditions when a rash occurs on skin that has been exposed to the sun. These are also referred to as photosensitive disorders or photodermatoses, and can be broadly categorized into the following medical terms: idiopathic photodermatoses, exogenous photodermatoses, photoexacerbated dermatoses, genetic photodermatoses, and metabolic photodermatoses. Sounds complicated, right? A sun allergy refers to a number of conditions when a rash occurs on skin that has been exposed to the sun. Let’s break it down: If, after spending a few hours in the sun, you develop an itchy red bumpy rash on your chest and arms, you likely have polymorphous light eruption (PMLE). Often when someone says they have a “sun allergy,” they are referring to this condition, which has rash-like symptoms. It is also one of the most common photodermatoses. PMLE most frequently occurs in women between the ages of 20-40. Polymorphous refers to the fact that the rash can look different on people, but it mostly appears as pink or red bumps on the arms, chest, and legs; the face is usually not affected. Typically, it occurs in spring or early summer, and is triggered by several hours of sun exposure after a long period of no sun exposure (winter!...

In the article “New treatments for chronic urticaria” by P Kolkhir et al (Ann Allergy Asthma Immunl 2020:124(1): 2-12), the following text has been removed. The article has been corrected online at https://doi.org/10.1016/j.anai.2019.08.014.
Technology is one of those items with which all clinicians (probably everyone) seem to have a love-hate relationship. The electronic medical record has made documenting and billing patient encounters much easier, yet at the same time, it seems to have erected a barrier between the patient and provider. Along with the growth of the electronic health record has been an explosion in the use of handheld devices and health-related applications (apps). These apps allow for more engagement and involvement with patients, including health monitoring by providers.
We thank the respondents to our article1 for their insightful comments. Although we have matched subjects in both cohorts by age, sex, comorbidities, and index date, Lin et al2 indicate a lack of adjustment for co-medication status, including the use of corticosteroids and disease-modifying antirheumatic drugs (DMARDs), in the propensity score. We agree that these medications are important confounders on fracture. We therefore had conducted multivariate analysis in t he published article by adjustment for corticosteroids, DMARDs, and phototherapy.
We read with great interest the article by Lin et al1 reporting the association of incidental fractures in patients with atopic dermatitis (AD). We appreciate the authors who collected data from Taiwan's National Health Insurance Research Database and conducted a great cohort study. Nevertheless, we highlight some key points.
