Generalized pustular psoriasis (GPP) is a rare, chronic skin disease, characterized by widespread pustules and erythema, often accompanied with systemic signs and symptoms. GPP flares occur episodically but may be protracted. Left untreated, GPP can be life‐threatening. Despite being first reported over 100 years ago, definitions and diagnostic criteria for GPP have been inconsistent and varied due, in part, to its rarity and a limited understanding of its pathogenesis. As such, many patients with GPP face delays in diagnosis and subsequent treatment. This manuscript aims to increase the recognition of GPP and provide foundational considerations to aid in the definition and diagnosis of this disease. [ABSTRACT FROM AUTHOR]

Objective: To provide family physicians with an understanding of the epidemiology, clinical features, diagnosis, and management of hidradenitis suppurativa (HS)., Sources of Information: A PubMed literature search was performed using the MeSH term hidradenitis suppurativa ., Main Message: Hidradenitis suppurativa is a chronic, recurrent, and debilitating skin condition. It is an inflammatory disorder of the follicular epithelium, but secondary bacterial infection can often occur. The diagnosis is made clinically based on typical lesions (nodules, abscesses, sinus tracts), locations (skin folds), and nature of relapses and chronicity. Multiple comorbidities are associated with HS, including obesity, metabolic syndrome, inflammatory bowel disease, and spondyloarthropathy. Although the lack of curative therapy and the recurrent nature makes HS treatment challenging, there are effective symptomatic management options., Conclusion: Family physicians should be suspicious of HS in patients presenting with recurrent skin abscesses at the skin folds. Family physicians play an important role in early diagnosis, initiation of treatment, and referral to a dermatologist before HS progresses to debilitating end-stage disease., (Copyright© the College of Family Physicians of Canada.)

Phototherapy and photochemotherapy are well-described treatment modalities for psoriasis in adults. Like many other treatments, the experience and long-term safety of their use in children is limited. We conducted a literature search and identified publications reporting the use of phototherapy and photochemotherapy in pediatric populations. This article summarizes the existing literature on this topic. Although many studies report good improvement with these treatment modalities, long-term safety data on their use is lacking for pediatric patients.
