Assessment of the bioavailability of topically applied drugs designed to act within or beneath the skin is a challenging objective. A number of different, but potentially complementary, techniques are under evaluation. The objective of this work was to evaluate in vitro skin penetration and stratum corneum tape-stripping in vivo as tools with which to measure topical diclofenac bioavailability from three approved and commercialized products (two gels and one solution). Drug uptake into, and its subsequent clearance from, the stratum corneum of human volunteers was used to estimate the input rate of diclofenac into the viable skin layers...

Hydralazine-induced small vessel vasculitis is a rare entity with a limited number of cases reported in the dermatologic literature. A characteristic pattern of acral pseudoembolic vesiculopustules with necrosis and ulceration has been suggested along with involvement of the aerodigestive tract, indicating mucosal involvement is an important feature of this disease. We report the case of a patient with hydralazine-induced vasculitis who exemplified this characteristic presentation associated with severe involvement of the aerodigestive tract and gastrointestinal tract bleeding...

Nanocosmeceuticals are promising applications of nanotechnology in personal care industries. Zinc oxide is an inorganic material that is non-toxic and skin compatible with self-cleansing and microbicidal properties. Herein, exploitation of colloidal zinc oxide nanoparticles (ZnONps) as potent biomaterial for a topical formulation of cosmetic and dermatological significance is employed. ZnONps were green synthesized using environmentally benign Adhatoda vasica leaf extract and characterized by UV-Vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), dynamic light scattering (DLS), high-resolution transmission electron microscopy (HR-TEM) and energy-dispersive X-ray spectroscopy (EDX)...

<p>Background: Dermatologists were historically well versed in the use of radiation therapy for the management of non-melanoma skin cancers and various inflammatory dermatologic conditions. With the advent of Mohs micrographic surgery and therapeutic discoveries for treating inflammatory dermatoses, radiotherapy assumed loss of a role in the clinical repertoire of the dermatologist. In recent years, its importance has again been realized for the management of non-melanoma skin cancers not amenable to surgical treatment or as adjuvant or palliative therapy...

Brittany Oliver, Serena Durrani, Joel L Cohen, Adam J Friedman
<p>Introduction: Nonmelanoma skin cancer (NMSC) is the most common malignancy in the US Primary prevention of NMSC with physical photoprotective measures are often not sufficient to impact skin cancer incidence in high-risk individuals. Chemoprevention is the use of agents to prevent, suppress, and reverse carcinogenic progression. Many agents have been investigated, but preclinical and clinical studies are often inconsistent.</p> <p>Methods: A cross-sectional study was designed to assess current practices, perceptions, and general knowledge of U...

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...

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...

Anti-TNFα agents have proved effective in the treatment of various inflammatory, rheumatologic, dermatologic, and gastrointestinal diseases. Severe respiratory tract infections of bacterial or fungal origin have emerged as important complications in patients receiving such treatments. The risk of infection due to anti-TNFα therapy is difficult to assess in these patients who are immunocompromised because of the underlying disease itself and of previous or concomitant immunosuppressive drugs. This excessive infection risk seems real, particularly in the first six months following treatment initiation, and higher for patients receiving anti-TNFα monoclonal antibodies than for those receiving soluble TNFα receptor...

REVIEW
James Leyden, Linda Stein-Gold, Jonathan Weiss
Acne-focused dermatology expert groups have consistently recommended that most patients with acne be treated with a combination of topical retinoid and antimicrobial therapy. This is based on clinical data as well as evidence that these drug classes have different and complementary mechanisms of action that target multiple aspects of acne's complex pathophysiology. Recent evidence-based guidelines for acne, including those from the American Academy of Dermatology (AAD) and the European Dermatology Forum (EDF), have agreed that retinoids have an essential role in this widespread disease...

REVIEW
Anupam Das, Saumya Panda
Topical corticosteroids (TCs) are the pillars of dermatotherapeutics. These drugs are the "magic molecules," provided they are used judiciously and appropriately, following a rational prescription. On exhaustive literature search in multiple databases, we found a significant evidence favoring the use of TCs in atopic eczema, localized vitiligo, psoriasis, chronic hand eczema, and localized bullous pemphigoid. However, contrary to conventional wisdom, we did not find any high-level scientific evidence in support of prescribing TCs in cutaneous lichen planus, sarcoidosis, and seborrhoeic dermatitis...
