Sensitization to benzyl salicylate and other allergens in patients with frontal fibrosing alopecia.

Background: Contact sensitization is frequent among patients with frontal fibrosing alopecia (FFA) (52%-76%).

Objective: To evaluate the frequency of sensitization/photosensitization in an FFA population.

Methods: A population of FFA patients were patch tested (Spanish Contact Dermatitis Research Group [GEIDAC] baseline; cosmetic and fragrance series), and photopatch tested (sunscreen series).

P-wave and interatrial block: New predictor for atrial high rate episodes in patients with cardiac implantable electronic devices.

Background: The presence of interatrial block (IAB) is associated with the development of atrial fibrillation (AF). The aim of this study was to determine whether P-wave duration and presence of IAB before the implantation of a cardiac implantable electronic device (CIED) are associated with the presence of atrial high rate episodes (AHRE), during long-term follow-up.

Methods: 380 patients (57% men; 75 ± 10 years) were included.
