BACKGROUND: Methotrexate (MTX) is an antimetabolite drug used in the treatment of cancers and autoimmune diseases and frequently in dermatology for cutaneous and/or arthritic psoriasis. Toxicities due to MTX overdosage are mainly cutaneous, hepatic and hematologic. Herein, we report a case of MTX overdosage presenting as an erosive and an inflammatory flare of preexisting psoriatic plaques and with new palmar lesions. PATIENTS AND METHODS: A 51-year-old male with a 6-year history of plaque psoriasis resistant to topical corticosteroids was started for the first time on MTX 20mg weekly...

Postinflammatory hyperpigmentation (PIH) occurs after various dermatoses, exogenous stimuli, and dermatologic procedures. The clinical course of PIH is chronic and unpredictable, although the probability of resolution of epidermal hyperpigmentation is better than those of dermal hyperpigmentation. PIH can be prevented or alleviated. When it does occur, the underlying inflammatory conditions should be sought and treated as the first step to reduce the progression of inflammation and PIH (which is an inflammatory consequence)...

BACKGROUND: Psoriasis and hidradenitis suppurativa (HS) exhibit distinct clinical features, but no studies have directly compared the health-related quality of life (HRQoL) in patients with moderate-to-severe manifestations of these conditions. OBJECTIVE: To determine which disease is associated with more severe HRQoL impairment. METHODS: Weighted averages of each of the following baseline HRQoL measures were determined and compared between HS and psoriasis populations from 5 clinical trials: Visual Analog Scale (VAS) for pain, Total Work Productivity Impairment, Dermatology Life Quality Index; EuroQOL 5D VAS, and Short Form-36 Health Survey...

Dermatosis papulosa nigra was first described by Aldo Castellani (1874-1971) more than 90 years ago, and it has since been presumed to be a variant of seborrheic keratosis. Despite their morphologic similarities both macroscopically and microscopically, key differences have yet to be explained. These lesions also exhibit different demographics, with dermatosis papulosa nigra having a predilection for dark-skinned individuals and a female predominance. No studies to date have investigated this, but studies assessing the mechanisms of similar dermatologic conditions may yield significant clues...

Although the surfaces of both the skin and oral mucosa are protected by squamous epithelial cells and fall within the scope of dermatologic practice, the oral cavity contains highly specialized structures and functions distinct from other skin biology and pathologic conditions and are also the purview of clinicians who care for patients with skin and mucosal diseases. We describe the distinct features of the tongue, mucosa, and salivary glands. In particular, we examine the composition and function of the saliva, with special focus on salivary biomarkers...

Genital aphthous ulcers can result from multiple conditions including febrile syndromes. Chikungunya infection manifests mainly as fever accompanied by polyarthralgia and pruritic rash. Nevertheless, healthcare providers should be alert to additional presentations. This is the case of a young woman presenting with painful genital ulcers after a three day prodome of fever and polyarthralgia. As a suspected case of Chikungunya infection and a clinical diagnosis of aphthae, treatment with oral prednisone for two weeks produced complete resolution of ulcers with no scarring...

With laser surgery, what you see is what you get. Visualizing the target for treatment, be it a port-wine stain, a cluster of spider veins, a tattoo or freckles, or simply photodamaged skin requires seeing through surface reflections, dry skin, and often quite dark laser goggles. The tool that has been indispensable to me in my practice is the Syris v900L polarizing and magnifying headlamp. This indispensable tool makes laser treatment more precise, effective, and easier by truly shining a light on the subject of a laser treatment...

In their article "Importing Injectables" in the September 2014 issue of the Journal of Drugs in Dermatology, Dr. Kenneth Beer and Karen Rothschild highlighted the possible harm to patients and practitioners from the use of unapproved botulinum toxin products - eg, Botox, Dysport, Xeomin, and Myobloc - and other cosmetic prescription drug products purchased from foreign or unlicensed suppliers.1 In the intervening years, the accuracy of their critique has been repeatedly demonstrated, as the dangers to patients' health, as well as to cosmetic practitioners' liberty, has only increased...

Photodynamic therapy becomes a widely spread method due to cancer growth in the world. However, to detect tumors at early stages, it is necessary to carry out diagnostic measures in a timely manner. Our aim was to test the developed pharmaceutical composition, which can be used for external application in early fluorescent diagnostics even in the absence of visual changes, as well as for therapy effectiveness control. Pharmacokinetic studies on laboratory animals and volunteers were carried out. The results have shown that the dipotassium salt of Yb3+-dimethoxyhematoporphyrin IX, which is highly soluble in water and stable in storage, is a promising marker for earlier diagnostics of tumors and can be used in dermatology, dentistry, gynecology, cosmetology, ear, nose, and throat diseases, veterinary, and in other areas of medicine...

An odontogenic cutaneous fistula is a pathological communication between the outer skin surface of the face and the oral cavity. Facial cutaneous fistula is a complication of odontogenic infection that is often misdiagnosed with skin infection. We report a rare case, which was diagnosed as basal cell carcinoma based on the biopsy of skin lesions in the patient who had been diagnosed with odontogenic cutaneous fistula. A 64-year-old male patient presented with a cutaneous odontogenic fistula. The patient had undergone surgical extraction of fistula tract and loose tooth before dermatology or plastic surgery consultation...

BACKGROUND: Advantages of mobile Augmented Reality (mAR) application-based learning versus textbook-based learning were already shown in a previous study. However, it was unclear whether the augmented reality (AR) component was responsible for the success of the self-developed app or whether this was attributable to the novelty of using mobile technology for learning. OBJECTIVE: The study's aim was to test the hypothesis whether there is no difference in learning success between learners who employed the mobile AR component and those who learned without it to determine possible effects of mAR...

Human skin, eye and hair color rely on the production of melanin, depending on its quantity, quality, and distribution, Melanin plays a monumental role in protecting the skin against the harmful effect of ultraviolet radiation and oxidative stress from various environmental pollutants. However, an excessive production of melanin causes serious dermatological problems such as freckles, solar lentigo (age spots), melasma, as well as cancer. Hence, the regulation of melanin production is important for controlling the hyper-pigmentation...
