Necrobiosis lipoidica is a granulomatous condition presenting as indolent atrophic plaques, often on the lower extremities. There is a multitude of case reports suggesting possible associations and documenting different therapeutic alternatives with varied success. Important complications include ulceration and the development of squamous cell carcinoma. The disease course is often indolent and recurrent despite treatment. This article reviews the etiopathogenesis, clinical presentations, and evidence for treatment alternatives of this condition.
Psoriasis and anxiety are chronic conditions with significant morbidity and there is evidence that they may exacerbate one another. There is little data on the prevalence of anxiety in psoriasis and the effect of psoriasis treatment on comorbid anxiety. The objective of this study was to perform a systematic review of the literature to describe the prevalence and severity of clinical anxiety disorders or anxiety symptoms among adult patients with psoriasis and characterize the effect of anti-psoriatic interventions on clinical anxiety disorders or anxiety symptoms. We searched PubMed, EMBASE, and the Cochrane Database using search terms 'psoriasis' and 'anxiety'. Results were tabulated and verified by two independent reviewers. Meta-analyses were not performed due to heterogeneity of data. Of 213 publications identified, 938 194 patients from 15 papers were included. The mean age ranged from 31.9-59.4 years old, with a mean PASI score of 7.65-22.8 (reported by nine studies) and a body surface area involvement of 25.9-39.8% (reported by two studies). The prevalence of anxiety in patients with psoriasis was 7-48%, which was significantly higher than healthy controls in two of three studies (HR 1.29-1.31, P = 0.001 and OR 2.91 [95% CI, 2.01-4.21], P < 0.001). Four of five studies (n = 2029) demonstrated an improvement in anxiety symptoms with psoriasis treatment. This review demonstrates a high prevalence of anxiety of adult patients with psoriasis suggesting that patients would benefit from systematic screening. Although the data suggest that anxiety may be improved through various psoriasis treatments, larger prospective randomized trials are needed to confirm this effect.
Despite the higher incidence among South Asians, South and East/Southeast Asian children have significantly less complicated clinical outcomes compared with Europeans.

Atopic dermatitis is a chronic, relapsing, intensely pruritic inflammatory skin disease that affects both children and adults. This article provides an overview of the epidemiology, clinical features, pathophysiology, complications, and specific investigations of atopic dermatitis. The current and novel therapies for the treatment of atopic dermatitis will be discussed.
GENERAL PURPOSE:
The purpose of this learning activity is to provide information about the diagnosis and management of atopic dermatitis (AD).
TARGET AUDIENCE:
This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care.
LEARNING OBJECTIVES/OUTCOMES:
After completing this continuing education activity, you should be able to:
1. Recall the diagnostic process of AD.
2. Identify nonpharmacologic therapies for skin care in patients with AD.
3. Explain the pharmacologic management of AD.

Cyclosporine is a systemic therapy used for control of severe atopic dermatitis (AD) in children. Although traditionally recommended at a dose of 5 mg/kg/day for 6 months, a longer duration of treatment may be necessary to bring a child with active and severe disease into remission. There are few data on the short- and long-term effectiveness of longer courses of therapy. This was a retrospective chart review of children treated with cyclosporine at a Canadian hospital-affiliated clinic between 2000 and 2013. Fifteen patients with adequate follow-up were identified. Twelve (80%) were male and the mean age at initiation of cyclosporine was 11.2 ± 3.4 years. The mean duration of cyclosporine therapy was 10.9 ± 2.7 months (range 7-15 months) at a starting dose of 2.8 ± 0.6 mg/kg/day. Of 12 patients (80%) who responded to cyclosporine, 5 patients (42%) had relapsed at a follow-up of 22.7 ± 15.0 months. The duration of therapy was longer in patients who did not relapse (17.7 ± 10.7 months) than in those who did (10.2 ± 2.7 months) (p = 0.06). Adverse events led to discontinuation in three patients (20%) and included infection-related complications in two patients and reversible renal toxicity in one. These results suggest that a longer duration of low-dose cyclosporine may help decrease the risk of relapse in patients with severe AD who are resistant to topical therapies.
Introduction: Many international guidelines for management of psoriasis exist and most have variations in grading evidence quality, strength of recommendations, and dosing. The objective of our review is to compare international guidelines published in the United Kingdom, Canada, Europe, and the United States for the management of moderate-to-severe plaque psoriasis. Methods: We conducted a literature review on systemic therapies and phototherapy for moderate-to-severe plaque psoriasis in adult patients. The British, Canadian, European, and American guidelines served as the key comparators in our review. To identify relevant supporting clinical trials not referenced in the guidelines, we conducted literature searches in PubMed and EMBASE. Two authors independently extracted data on indications, dosing, efficacy, evidence grade, and strength of clinical recommendation for each therapy. Results: Monoclonal antibodies directed toward tumour necrosis factor and interleukin (IL)-12/23 received the strongest recommendations for treatment of moderate-to-severe plaque psoriasis, supported by robust, high-quality randomized controlled trials (RCTs). Newer agents such as IL-17 and IL-23 inhibitors are not referenced in most guidelines. There are fewer RCTs for conventional therapies and few head-to-head comparisons with biologics, making it difficult to draw direct comparisons. Among older agents, methotrexate is most strongly recommended for long-term maintenance and cyclosporine is recommended for short-term control of flares. Conclusion: Physicians should individualize psoriasis-management strategies based on medication tolerance, efficacy, safety, patient comorbidities, availability of the medication, and patient preference.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
