Alopecia areata and risk of common infections: a population-based cohort study.

Background: It is not known whether alopecia areata (AA) is associated with a greater or reduced risk for infection.

Aim: We undertook a population-based study exploring associations between AA and common infections.

Methods: We extracted primary care records from the UK Oxford-Royal College of General Practitioners Research and Surveillance Centre database (trial registration: NCT04239521).

The associated burden of mental health conditions in alopecia areata: a population-based study in UK primary care.

Background: Alopecia areata (AA) is a common cause of nonscarring hair loss that can have a profound psychological impact.

Objectives: To assess the co-occurrence of depression and anxiety in adults with AA compared with the general population, and to evaluate the mental health treatment burden and impact on time off work and unemployment.

Methods: In total, 5435 people with newly diagnosed AA in UK primary care were identified from the Oxford Royal College of General Practitioners Research and Surveillance Centre network database, and matched to 21 740 controls.

Epidemiology, management and the associated burden of mental health illness, atopic and autoimmune conditions, and common infections in alopecia areata: protocol for an observational study series.

Introduction: Alopecia areata (AA) is a common cause of immune-mediated non-scarring hair loss. Links between AA and common mental health, autoimmune and atopic conditions, and common infections have previously been described but remain incompletely elucidated and contemporary descriptions of the epidemiology of AA in the UK are lacking.

Methods And Analysis: Retrospective study series using a large population-based cohort (5.

Genome-wide association study in frontal fibrosing alopecia identifies four susceptibility loci including HLA-B*07:02.

Frontal fibrosing alopecia (FFA) is a recently described inflammatory and scarring type of hair loss affecting almost exclusively women. Despite a dramatic recent increase in incidence the aetiopathogenesis of FFA remains unknown. We undertake genome-wide association studies in females from a UK cohort, comprising 844 cases and 3,760 controls, a Spanish cohort of 172 cases and 385 controls, and perform statistical meta-analysis.

Dramatic and persistent loss of eyelashes.

Although most paediatric hair loss presenting to clinicians is due to alopecia areata, unusual patterns should prompt a careful history.

Photoletter to the editor: Dermatitis herpetiformis co-localised with vitiligo in a patient with autoimmune polyglandular syndrome.

We report a case of dermatitis herpetiformis co-localised with segmental vitiligo in a 37-year-old woman with a background history of autoimmune polyglandular syndrome type 2. We propose genetic mosaicism as a possible mechanism. There has only been one previous case report in which dermatitis hepetiformis co-localised in close proximity but not exclusively within vilitigo in a patient with autoimmune thyroiditis.

Hair loss in hospital medicine: a practical guide.

Alopecia may indicate underlying systemic disease and is associated with significant impairment of quality of life. A thorough history and examination, including specialist techniques, can give vital clues to the aetiology. This article provides an overview of the common and important hair loss disorders for the busy clinician.
