Educational, labour market and relationship outcomes in people with acne.

Background: Although acne is associated with scarring, mental health comorbidities and bullying, little is known about its impact on socio-economic outcomes.

Objectives: To examine the association between acne and educational, labour market and relationship outcomes.

Methods: We conducted a nationwide registry-based cohort study in Denmark.

Severe Mental Illness Among Adults with Atopic Eczema or Psoriasis: Population-Based Matched Cohort Studies within UK Primary Care.

Background: Existing research exploring associations between atopic eczema (AE) or psoriasis, and severe mental illness (SMI - ie, schizophrenia, bipolar disorder, other psychoses) is limited, with longitudinal evidence particularly scarce. Therefore, temporal directions of associations are unclear. We aimed to investigate associations between AE or psoriasis and incident SMI among adults.

Long-term oral antibiotic use in people with acne vulgaris in UK primary care: a drug utilization study.

Background: The inappropriate use of antibiotics is understood to contribute to antimicrobial resistance. Oral antibiotics are regularly used to treat moderate-to-severe acne vulgaris. In practice, we do not know the typical length of oral antibiotic treatment courses for acne in routine primary care and what proportion of people receive more than one course of treatment following a new acne diagnosis.

The association between penile cancer and HIV infection: A literature review.

Penile cancer is a rare malignancy which HIV infection appears to increase the risk of. The magnitude of this risk and the pathogenesis remain unclear. A comprehensive review of the literature was undertaken using conventional search strategies.

Rates of serious clinical outcomes in survivors of hospitalisation with COVID-19 in England: a descriptive cohort study within the OpenSAFELY platform.

Patients surviving hospitalisation for COVID-19 are thought to be at high risk of cardiometabolic and pulmonary complications, but quantification of that risk is limited. We aimed to describe the overall burden of these complications in people after discharge from hospital with COVID-19.   Working on behalf of NHS England, we used linked primary care records, death certificate and hospital data from the OpenSAFELY platform.

Vitamin D Deficiency or Supplementation and the Risk of Human Herpesvirus Infections or Reactivation: A Systematic Review and Meta-analysis.

Background: Vitamin D may protect against respiratory virus infections, but any association with herpesviruses is unclear.

Methods: We undertook a systematic review of vitamin D deficiency or supplementation and the risk of 8 human herpesviruses. Six databases and 4 gray literature databases were searched for relevant cohort studies, case-control studies, and clinical trials.

Is there an association between long-term antibiotics for acne and subsequent infection sequelae and antimicrobial resistance? A systematic review protocol.

Introduction: Antimicrobial resistance (AMR) is a global health emergency. Acne vulgaris is a highly prevalent condition and the dominant role antibiotics play in its treatment is a major concern. Antibiotics are widely used in the treatment of acne predominantly for their anti-inflammatory effect, hence their use in acne may not be optimal.

Vitamin D deficiency or supplementation and the risk of human herpesvirus infections or reactivation: a systematic review protocol.

Introduction: Human herpesviruses induce lifelong latent infections and may reactivate as the immune system deteriorates. Recent studies have suggested that vitamin D, an essential element of bone health, may have some effect of protecting against infections, but investigations of its potential to prevent herpesvirus infection or reactivation are limited. We will review the current literature examining vitamin D and the risk of herpesvirus infections or reactivation.

Lack of association of biologic therapy for psoriasis with psychiatric illness: An electronic medical records cohort study.

Background: Psoriasis and biologic therapies have been associated with psychiatric illnesses.

Objective: To determine if persons with psoriasis or those exposed to biologics are more likely to develop a psychiatric illness.

Methods: Retrospective electronic medical records cohort study.

Trends in Oral Antibiotic Prescription in Dermatology, 2008 to 2016.

Importance: Dermatologists prescribe more oral antibiotic courses per clinician than any other specialty, and this use puts patients at risk of antibiotic-resistant infections and antibiotic-associated adverse events.

Objective: To characterize the temporal trends in the diagnoses most commonly associated with oral antibiotic prescription by dermatologists, as well as the duration of this use.

Design, Setting, And Participants: Repeated cross-sectional analysis of antibiotic prescribing by dermatologists from January 1, 2008, to December 31, 2016.

Genital contact dermatitis: a retrospective analysis.

Background: many topical products are used in the genital region. Allergic contact dermatitis (ACD) may develop from product use or due to treatment of an underlying dermatosis.

Objectives: our goal was to identify the frequency of ACD and identify top allergens in the genital region.

Delayed patch test reading after 5 days: the Mayo Clinic experience.

Background: Some patients may have delayed allergic patch test reactions that are not identified with a typical 5-day reading protocol.

Objective: To identify allergens with delayed-positive reactions and to determine whether a late reading (day 7-9) can be substituted for the day-5 reading.

Methods: We retrospectively reviewed medical records of patients who underwent patch testing for suspected allergic contact dermatitis from October 1997 through December 2006 and returned for delayed readings between days 7 and 10 or beyond.
