BACKGROUND: Generalized pustular psoriasis (GPP) is a relapsing-remitting chronic disease characterized by painful pustules with systemic symptoms that negatively impacts quality of life. The psychosocial and economic burden of this rare condition is not well characterized. OBJECTIVES: To qualitatively characterize the cumulative burden of generalized pustular psoriasis on patients' quality of life and psychosocial wellbeing. METHODS: A retrospective chart review of patients with generalized pustular psoriasis was performed to collect demographic information, followed by prospective semi-structured clinical interviews...

BACKGROUND: Alopecia areata (AA), a chronic autoimmune disorder causing non-scarring hair loss, has a greater prevalence in the pediatric population. Like many visible dermatologic disorders, AA can cause significant psychosocial impairment, particularly in children who are undergoing critical periods of psychosocial development. This paper investigates the psychosocial impact of AA on children. METHODS: A systematic review was conducted using PRISMA guidelines...

BACKGROUND: Actinic keratoses (AKs) present on sun-exposed sites and are considered precursors of cutaneous squamous cell carcinoma (cSCC). A better understanding of the experiences of patients with this condition may improve patient-provider relationships and guide the introduction of shared-decision making (SDM) to treatment decisions. OBJECTIVES: To develop a patient decision aid (PDA) for field treatment of multiple actinic keratoses in line with the International Patient Decision Aid Standards (IPDAS), by (i) characterising the burden and lived experiences of patients with multiple AKs, (ii) understanding the decisional needs of patients requiring field treatment and (iii) exploring clinician preferences regarding field treatment for multiple AKs...

Primary Cutaneous CD4+ Small/Medium T-Cell Lymphoproliferative Disorders (SMPLPD), also known as PCS-TCLPD, represent a rare group of hematologic diseases primarily affecting the skin. In this retrospective single-centre case series study, we aimed to investigate the demographic, clinical, therapeutic, and prognostic aspects of SMPLPD. We collected data from cases diagnosed between 2010 and the present, employing histopathological and immunohistochemical methods following WHO criteria. We included 22 patients with a median age of 61...

We report 10 cases of oral squamous cell carcinoma (SCC) post-haematopoietic stem cell transplant (HSCT).. Median latency from HSCT to oral SCC diagnosis was 10 years (range: 4-17 years) with 90% reporting a history of chronic graft-versus-host disease (cGVHD) and 40% exhibited active severe manifestations of oral GVHD. Clinical findings at diagnosis included induration, ulceration, tenderness, bleeding, hyperkeratosis, speckling and lymphadenopathy. The tongue and buccal mucosa were the commonest sites affected...

BACKGROUND: ChatGPT® (OpenAI; California, USA) is an open-access chatbot developed using artificial intelligence (AI) that generates human-like responses. OBJECTIVE: To evaluate the ChatGPT-4's concordance with three dermatologic surgeons on reconstructions for dermatological surgical defects. METHODS: A total of 70 cases of non-melanoma skin cancer treated with surgery were obtained from clinical records for analysis. A list of 30 reconstruction options was designed by the main authors which included primary closure, secondary skin closure, skin flaps and skin grafts...

BACKGROUND: Herpes zoster (HZ) rarely results in later death, but predictive biomarkers for mortality necessitates further elucidation. OBJECTIVE: To investigate immune dynamics prior to HZ event, risk factors for HZ onset, and immune status at initial HZ. METHODS: This retrospective study extracted the absolute neutrophil and lymphocyte counts (ANC and ALC, respectively) at the initial HZ date and up to 30 days before HZ. A follow-up survey was completed within 180 days of the onset of illness...

Chronic urticaria (CU) is characterized by wheals, angioedema, or both lasting for ≥ 6 weeks with chronic spontaneous urticaria (CSU) being the most common subtype. Omalizumab-resistant CSU cases represent an unmet clinical need. In this study, we aimed to assess the prevalence and predictors of omalizumab failure in a large cohort of CU patients and assess the effectiveness of dupilumab for omalizumab-recalcitrant CU. Of 338 CU patients, 33 received omalizumab. 69.7% (23 patients) were responders and 30...

BACKGROUND: Cutaneous polyarteritis nodosa (cPN) is a necrotizing arteritis of medium-sized vessels limited to the skin. Because of its rarity and the diversity of its clinical manifestations, there is no consensus treatment. Moreover, there are no established indicators that predict disease severity or its outcome. OBJECTIVES: To investigate clinico-laboratory features that predict patients requiring systemic therapy, including corticosteroids, to control the disease activity...
