Psoriasis is a worldwide chronic inflammatory disease, involving both skin and joints. In order to characterize psoriasis in Han Chinese population, we conducted this nationwide prospective and hospital based survey, in which 56 hospitals with departments of dermatology participated, located in 33 cities across China. A total of 12,031 outpatients with psoriasis were registered during 2009 to 2010, which the data was collected by standard questionnaires. The main data acquisition included demographics, family history, disease status and other comorbidities...

Lichenoid keratosis (LK), also known as benign lichenoid keratosis or lichen planus-like keratosis, is a solitary, pink to red-brown scaly plaque representing a host immunological response to a variety of precursor lesions. LK is often misdiagnosed as a dermatological malignancy owing to its clinical resemblance to basal cell carcinoma (BCC) or Bowen disease. We performed a retrospective analysis of the pathology records of a series of LK lesions with reference to the demographic features and accuracy of clinical diagnosis...

Pyoderma gangrenosum (PG) is a chronic inflammatory disease of unknown cause that presents as an inflammatory and ulcerative disorder of the skin. PG is often associated with an underlying systemic disease. However, the frequencies of the underlying diseases are unclear in Japanese patients. In this retrospective, observational study, all patients diagnosed with PG who visited dermatology departments of nine regional hospitals in and around Ibaraki Prefecture were collected from 1982 to 2011 or 2014. The diagnoses of PG were based on the characteristic clinical and histological appearances and ruling out of infection...

Medical photography, and in particular dermatological imagery, is often assumed to provide an objective, and functional, representation of disease and that it can act as a diagnostic aid. By contrast, artistic conceptions of the images of the body tend to focus on interpretative heterogeneity and ambiguity, aiming to create or explore meaning rather than enact a particular function. In her 2015 retrospective exhibition at the Tate Modern, South African artist Marlene Dumas questions these disciplinary divides by using medical imagery (among other photographic sources) as the basis for her portraits...

REVIEW
Janin Lehmann, Christina Seebode, Steffen Emmert
Genodermatoses comprise a clinically heterogeneous group of mostly devastating disorders affecting the skin. To date, treatment options have in general been limited to symptom relief. However, the recent technical evolution in genome editing has ushered in a new era in the development of causal therapies for rare monogenetic diseases such as genodermatoses. The present review revisits the advantages and drawbacks of engineered nuclease tools currently available: zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), meganucleases, and - the most innovative - clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) nuclease 9 (CRISPR/Cas9) system...

BACKGROUND: In the last few decades, a better knowledge of the inflammatory pathways involved in the pathogenesis of Inflammatory Bowel Disease (IBD) has promoted biological therapy as an important tool to treat IBD patients. However, in spite of a wider spectrum of biological drugs, a significant proportion of patients is unaffected by or lose their response to these compounds, along with increased risks of infections and malignancies. For these reasons there is an urgent need to look for new pharmacological targets...

Psychoneurocutaneous medicine is an important and rapidly growing field. It is an integrative science created to address the interaction between the mind, nervous system and skin. Four major fields are involved: psychiatry, psychology, neurology and dermatology. The history of psychoneurocutaneous medicine is old and fascinating. Even though it is a young science only established in the last century, allusions to the nervous system and diseases of the skin can be traced back thousands of years in the literature...

BACKGROUND: Synthetic fragrances and natural essential oils (EOs) are used in perfumery and found in various cosmetics. Essential oils are also increasingly used to promote wellness. In previous studies, the sensitization potential of some EOs has been identified; however, the current prevalence of sensitivity is largely unknown. OBJECTIVES: The aim of this study was to determine frequency of positive patch-test reactions to EOs tested in the baseline series, along with 3 fragrance markers (FMs) (fragrance mix I, fragrance mix II, and Myroxylon pereirae), in consecutive patients in the US/Canadian North American Contact Dermatitis Group (NACDG) (2009-2014) and the central European, trinational Information Network of Departments of Dermatology (IVDK) (2010-2014)...

Pruritus is a major symptom of several dermatological diseases but has limited therapeutic options available. Animal models replicating the pathophysiology of pruritus are needed to support the development of new drugs. Induction of pruritus by chloroquine (CQ) in mice is widely used, although, as with similar models, it has low throughput and does not distinguish between anti-pruritic effects and confounding factors such as sedation. To overcome these issues, we incorporated into the model an automated system that measures both scratching and locomotor behaviour simultaneously...

OBJECTIVE: Psoriasis is a chronic immune-mediated disorder of the skin. The disease manifests itself with red or silvery scaly plaques distributing over the lower back, scalp, and extensor aspects of limbs. Several medications are available for the treatment of psoriasis; however, high rates of remission and side-effects still persist as a major concern. Siddha, one of the traditional systems of Indian medicine offers cure to many dermatological conditions, including psoriasis. The oil prepared from the leaves of Wrightia tinctoria is prescribed by many healers for the treatment of psoriasis...

Approximately one in four patients treated with anti-TNF agents (infliximab, etanercept, adalimumab, certolizumab, and golimumab) develops cutaneous adverse events, typically months to years after the initiation of treatment, with xerosis cutis, eczema (often psoriasiform), psoriasis, palmoplantar pustulosis, cutaneous infections, alopecia, and skin cancer being the most frequently encountered. The typical skin lesion of anti-tumor necrosis factor (TNF)-treated patients is orange-red psoriasiform eczema affecting the flexures, genitalia, scalp, or face, with high susceptibility to bacterial superinfection with Staphylococcus aureus...

In 2002, intracellular protein complexes known as the inflammasomes were discovered and were shown to have a crucial role in the sensing of intracellular pathogen- and danger-associated molecular patterns (PAMPs and DAMPs). Activation of the inflammasomes results in the processing and subsequent secretion of the pro-inflammatory cytokines IL-1β and IL-18. Several autoinflammatory disorders such as cryopyrin-associated periodic syndromes and Familial Mediterranean Fever have been associated with mutations of genes encoding inflammasome components...

Calciphylaxis is associated with significant morbidity and mortality. Palliative care (PC) is a subspecialty that treats the pain and stress of serious illness. We performed a systematic review to assess whether quality of life (QoL) indices and the role of palliative care have been studied in calciphylaxis patients. We hypothesize PC services are underutilized to address reduced QoL in calciphylaxis. Several databases were searched from inception to October 2016 according to modified PRISMA criteria. We searched for papers about calciphylaxis that mentioned the symptoms and supportive needs of patients, QoL or outcome measures to report symptom severity, and the involvement of PC...
