Background: Alopecia describes a group of dermatological conditions characterised by hair loss, which are either non-scarring or scarring in nature, and range from bald patches to complete body hair loss, to general thinning. In the UK, the General Practitioner (GP) is typically the first point of contact, and some patients are referred for specialist dermatology consultation. However, little is known about how individuals with alopecia in the UK experience the care provided by the National Health Service.

Background: With the Experience Sampling Method (ESM) participants are asked to provide self-reports of their symptoms, feelings, thoughts and behaviours in daily life. This preregistered systematic review assessed how ESM is being used to monitor emotional well-being, somatic health, fatigue and pain in children and adolescents with a chronic somatic illness.

Methods: Databases were searched from inception.

Having a visible difference caused by an appearance-altering condition or injury can impact psychosocial wellbeing. It remains unestablished whether the time at which a visible difference manifests, namely pre-memory (congenital) or later (acquired), predicts psychosocial outcomes associated with adjustment. In this survey study of 331 adults with visible differences, we tested whether their type, congenital (n = 161) or acquired (n = 170), would predict four key psychosocial outcomes: Appearance satisfaction, social appearance anxiety, life disengagement and intimacy distress.

Introduction: Alopecia areata (AA) is a non-scarring hair loss condition, subclassified into AA, alopecia universalis, and alopecia totalis. There are indications that people with AA experience adverse psychosocial outcomes, but previous studies have not included a thorough meta-analysis and did not compare people with AA to people with other dermatological diagnoses. Therefore, the aim of this systematic review and meta-analysis was to update and expand previous systematic reviews, as well as describing and quantifying levels of anxiety, depression, and quality of life (QoL) in children and adults with AA.

A visible difference to the face or body may challenge adolescents' adjustment and engagement in life activities, where some require psychosocial support. However, evidence is limited for whether existing interventions for this adolescent group reduce social or appearance-related distress. We therefore conducted a parallel-group, randomised control trial to evaluate the effectiveness of Young Person's Face IT, a self-guided web-based psychosocial intervention developed for adolescents with a visible difference who experience distress.

Objective: Life can be challenging for children with a visible difference due to a medical condition, and they might be at risk for emotional and behavioral problems. This study examines emotional and behavioral problems in children with a cleft lip with or without palate (CL ± P) or an infantile hemangioma (IH) in relation to the visibility of the condition, the presence of additional condition-related problems, and parental affect.

Setting: This cross-sectional study took place in an academic medical hospital in the Erasmus MC Sophia Children's Hospital, the Netherlands.

Introduction: This paper outlines the study protocol for the Dutch Young People (YP) Face IT Study. Adolescents with a visible difference (ie, disfigurement) often experience challenging social situations such as being stared at, receiving unwanted questions or being teased. As a consequence, some of these adolescents experience adverse psychosocial outcomes and appearance-related distress.

Leading biological hypotheses propose that biological changes may underlie major depressive disorder onset and relapse/recurrence. Here, we investigate if there is prospective evidence for biomarkers derived from leading theories. We focus on neuroimaging, gastrointestinal factors, immunology, neurotrophic factors, neurotransmitters, hormones, and oxidative stress.
