Pyoderma Gangrenosum (PG) is a rare ulcerative cutaneous condition with distinctive characteristics, and the aetiology is not clear yet. PG is commonly associated with inflammatory bowel disease (Ulcerative Colitis and Crohn's disease). The features of PG are not specific histopathologically and for this reason diagnosis is based on clinical feature. There is no single successful treatment for PG. In fact certain type of lesions respond more readily to some therapies than others. Local treatments (advanced wound care, local corticosteroids, local immunomodulator agents) may be sufficient for some clinical features, while others may be required systemic therapy (corticosteroids, immunosuppressive therapy, intravenous immune globulins, TNF-alpha blocking agents). We present four cases of PG associated with inflammatory bowel diseases treated with different therapeutic approaches.

Characterization of cognitive decline in long-duration type 1 diabetes by cognitive, neuroimaging and pathological examinations.
JCI Insight

Dianne Hoppes Nunnally Laboratory Research Division, Joslin Diabetes Center, Boston, United States of America.
Background: We aimed to characterize factors associated with the under-studied complication of cognitive decline in aging people with long-duration type 1 diabetes (T1D).
Methods: Joslin "Medalists" (n = 222; T1D ≥ 50 years) underwent cognitive testing. Medalists (n = 52) and age-matched non-diabetic controls (n = 20) underwent neuro- and retinal imaging.
Reporting of concomitant and rescue topical therapies in atopic dermatitis randomised controlled trials evaluating a systemic treatment: a scoping review.

Centre of Evidence Based Dermatology, School of Medicine, Faculty of Medicine & Health Sciences, University of Nottingham, UK.
Background: Randomised controlled trials (RCTs) evaluating new systemic treatments for atopic dermatitis (AD) have increased dramatically over the last decade. These trials often incorporate topical therapies either as permitted concomitant or rescue treatments. Differential use of these topicals post-randomisation introduces potential bias as they may nullify or exaggerate treatment responses.

The co-circulation of influenza and SARS-CoV-2 has led to co-infection events, primarily affecting children and older adults, who are at higher risk for severe disease. Although co-infection prevalence is relatively low, it is associated with worse outcomes compared to mono-infections. Previous studies have shown that the outcomes of co-infection depend on multiple factors, including viral interference, virus-host interaction and host response.

Traumatic brain injury (TBI)-associated neuroinflammation and neurotoxicity can induce gastrointestinal dysfunction through the brain-gut axis. Partially hydrolyzed guar gum (PHGG) was demonstrated to exert beneficial health effects by altering gut microbiota and short-chain fatty acids (SCFAs) production. Our study aimed to explore the effects of PHGG on gastrointestinal dysfunction in TBI mouse models.

Lichen nitidus (LN) is a rare inflammatory skin condition characterized by small, shiny, flat-topped papules, commonly affecting children and young adults. Its etiology remains unclear, though immune-mediated pathways are suspected. LN is often asymptomatic, with papules primarily on the trunk, upper limbs, and genitalia.
