Background: Allergic contact dermatitis (ACD) in the eye region caused by topical eye medications is difficult to diagnose and may be overlooked. Objective: To study the characteristics and causative agents in patients with ACD caused by topical eye medications in a Danish tertiary dermatology department. Methods: A retrospective study of 318 patients, patch tested between 2013 and 2021 due to suspected ACD to topical eye medications. All patients were tested with a locally developed eye medication series, some were additionally tested with suspected eye medications. Medical records were studied in patch test positive patients. Results: Contact allergy to a topical eye allergen/medication was found in 12.9% (n = 41) of 318 patients, and culprit allergens were phenylephrine (6.9%), timolol (2.5%) and ketotifen (1.6%). Patch test positive patients were often previously diagnosed with cataract (29.3%) or glaucoma (24.4%), and the majority reported more than one previous reaction. Initial symptoms were oedema (56.0%), erythema (48.8%) and dermatitis (31.7%) in the eye region, and facial dermatitis was also seen. Conclusions: Patients with symptoms from the eye region who have been using topical eye medications should be patch tested with ingredients from commonly used eye medications supplemented by the products tested 'as is'.

Atopic diseases such as atopic dermatitis, food allergy, allergic rhinoconjunctivitis, and/or asthma are common. In Denmark, however, there are multiple referral pathways for these diseases in the healthcare system and they are poorly understood. To describe how children with atopic diseases navigate their way through the Danish healthcare system, a questionnaire was distributed to children aged ≤ 17 years, who were being treated for atopic diseases between August 2020 and June 2021, either by a practising specialist or a hospital department, in the Capital Region of Denmark. A total of 279 children completed the questionnaire and most were referred to a specialist or to a hospital by their general practitioner. No "common track" to hospital existed for patients with ≥ 3 atopic diseases. These patients were more often referred to a hospital compared with children with 2 atopic diseases or fewer (odds ratio [OR] 3.79; 95% CI 2.07-7.24). The primary determinants for hospital treatment were food allergy (OR 4.69; 95% CI 2.07-10.61) and asthma (OR 2.58; 95% CI 1.18-5.63). In conclusion, children with multiple atopic diseases were more likely to be referred to hospital departments than to practising specialists, mainly due to food allergies.

Aims: Evaluation of patients with primary mitral valve insufficiency (MI) is best supported by quantitative measures. Cardiovascular magnetic resonance imaging (CMR) offers flow and cardiac chamber volume quantification. We studied cardiac remodelling with CMR to determine MI regurgitation volumes (MIVol) related to severe MI., Methods and Results: In total, 24, 20, and 28 patients determined to have mild, moderate, and severe primary MI, respectively, were studied. Combining cine stacks with phase-contrast velocity mapping across the ascending aorta, CMR-determined MIVol was reproducibly obtained as the difference between left ventricular (LV) stroke volume and aortic forward flow (Aoflow). With increasing MI severity, MIVol, left heart volumes, and pulmonary venous diameters increased (P < 0.01). Severe MI with LV end-systolic diameter of 40 mm was signified by MIVol >40 mL, MI regurgitant fraction >0.30, LV end-diastolic volume (LVEDV(i)) >108 mL m(-2), and a total left heart volume >188 mL m(-2) with dilated pulmonary veins and a LVEDV/right ventricular EDV ratio >1.2. In severe MI, LV ejection fraction was unaffected, but the Aoflow and the peak ejection rate indexed to LVEDV were lowered (P < 0.05). In surgical patients, the MIVol correlated to the decrease in LV dimension after valve surgery (P < 0.02)., Conclusion: CMR provides a reproducible quantitative technique for evaluation of MI, as MIVol and cardiac chamber volumes can be held against diagnostic cut-off values. The Aoflow and peak ejection rate indexed to LVEDV may reveal early LV systolic dysfunction in patients with severe MI. Severe MI is related to lower MI regurgitation volume and fraction than previously believed., (Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2016.
