Estimating the healthcare burden of Prurigo Nodularis in England: a CPRD database study.

Prurigo nodularis (PN) is a skin disease characterized by intensely itchy skin nodules and is associated with a significant healthcare resource utilization (HCRU). This study aimed to estimate the HCRU of patients in England with PN overall and moderate-to-severe PN (MSPN) in particular. This retrospective cohort study used data from the Clinical Practice Research Datalink and Hospital Episode Statistics in England.

Development of the acne-specific quality of life questionnaire Quality of Life Relevance-Acne.

Background: Participating members of the European Academy of Dermatology and Venereology Task Forces on quality of life (QoL) and Patient Oriented Outcomes and Acne, Rosacea and Hidradenitis Suppurativa initiated data collection in 9 European countries and formed the list of the most relevant topics for acne patients.

Objective: The aim of this study was to develop a new acne-specific health-related QoL instrument based on the list of the most relevant topics for acne patients.

Methods: After assessment by acne patients ( = 715) on how clear and relevant the items in the prototype questionnaire were, a group of experts on acne and QoL performed discussions on items inclusion, which resulted in a series of 21 items.

Which Health-Related Quality of Life Items Most Affect Acne Patients?

Background: Health-related quality of life (HRQoL) assessment in patients with acne is recommended by several national guidelines. There are several acne-specific HRQoL instruments.

Objectives: Participants of the European Academy of Dermatology and Venereology (EADV) Task Forces (TFs) on QoL and Patient Oriented Outcomes (PO) and Acne, Rosacea, and Hidradenitis Suppurativa (ARHS) agreed to scrutinize aspects of existing acne-specific HRQoL instruments for their relevance in international study.

A Real-World Data Study on the Healthcare Resource Use for Uncontrolled Moderate-to-Severe Atopic Dermatitis in Secondary Care in the United Kingdom Prior to the Introduction of Biologic Treatment.

Background: Whilst there is international evidence around the high healthcare resource utilization (HRU) associated with atopic dermatitis (AD), there is a lack of published data from the United Kingdom (UK).

Methods: A retrospective, descriptive, observational study was conducted to evaluate the burden of moderate-to-severe AD on the National Health Service (NHS) in an adult UK population treated with traditional standard of care prior to the introduction of biologics. Patients (n=59) were recruited from 6 UK NHS Hospital Trusts and observed over three years.

Treatments for primary delusional infestation.

Background: Primary delusional infestation (DI) is a primary psychiatric disorder characterised by delusions and abnormal tactile sensations. The pathophysiology is undecided and treatment includes both pharmacological and non-pharmacological options. There is currently no Cochrane Review of the treatments used.

Evaluation of psoriasis patients' attitudes toward benefit-risk and therapeutic trade-offs in their choice of treatments.

Objective: Treatment options for psoriasis offer trade-offs in terms of efficacy, convenience, and risk of adverse events. We evaluated patients' preferences with respect to benefit-risk in the treatment of psoriasis.

Methods: A discrete choice experiment was conducted in adults from the UK with moderate-to-severe psoriasis using an orthogonal design with 32 hypothetical choice sets.

Children with a mother with delusional infestation--implications for child protection and management.

Delusional infestation (DI) is a reportedly uncommon psychocutaneous condition in which an individual holds a fixed, false belief of pathogenic infestation of the skin or body contrary to medical evidence. There are reports of such a delusion being shared with family members or close friends (folie a deux/famillie), but the implications of DI induced in children have not been discussed. We describe the case of a mother with DI whose children subsequently shared her belief.
