Paraneoplastic pemphigus (PNP) is a fatal autoimmune blistering disease associated with an underlying malignancy. It is a newly recognized blistering disease, which was first recognized in 1990 by Dr Anhalt who described an atypical pemphigus with associated neoplasia. In 2001, Nguyen proposed the term paraneoplastic autoimmune multiorgan syndrome because of the recognition that the condition affects multiple organ systems. PNP presents most frequently between 45 and 70 years old, but it also occurs in children and adolescents...

Benign familial chronic pemphigus or Hailey-Hailey disease is caused by an autosomal dominant mutation in the ATP2C1 gene leading to suprabasilar acantholysis. The disease most commonly affects intertriginous areas symmetrically. The chronic nature of the disease and multiple recurrences make the disease bothersome for patients and a treatment challenge for physicians. Treatments include topical and/or systemic agents and surgery including laser. This review summarizes the available treatment options.

Acne vulgaris is a common skin condition associated with multiple factors. Although mostly presenting alone, it can likewise present with features of hyperandrogenism and hormonal discrepancies. Of note, hormonal therapies are indicated in severe, resistant-to-treatment cases and in those with monthly flare-ups and when standard therapeutic options are inappropriate. This article serves as an update to hormonal pathogenesis of acne, discusses the basics of endocrinal evaluation for patients with suspected hormonal acne, and provides an overview of the current hormonal treatment options in women...

The hands, just like the face, are highly visible parts of the body. They age at a similar rate and demonstrate comparable changes with time, sun damage, and smoking. Loss of volume in the hands exposes underlying tendons, veins, and bony prominences. Rejuvenation of the hands with dermal fillers is a procedure with high patient satisfaction and relatively low risk for complications. This study will review relevant anatomy, injection technique, clinical safety, and efficacy of dermal filler volumization of the aging hand...

Confluent and reticulated papillomatosis (CRP) of Gougerot and Carteaud was first typified in 1927. With the help of electron microscopy, it has been elucidated that CRP arises due to aberrant keratinization. However, till date, there is no clear consensus on the etiologic trigger for CRP. Prevailing postulates include a bacterial trigger by Dietzia papillomatosis (type strain N 1280(T)), an exaggerated cutaneous response to Malassezia furfur, an endocrine basis stemming from insulin resistance, ultraviolet light-induced epidermal change, amyloid deposition, and a loss-of-function mutation in keratin 16...

BACKGROUND: Ingenol mebutate gel is a topical field treatment for actinic keratosis (AK). The treatment elicits application-site reactions in most patients. This analysis evaluated the relationship between the severity of reactions and the speed of their resolution. METHODS: Patients in Phase III studies were treated for AKs on the face (n=218), scalp (n=56), and trunk and extremities (n=209). All of the patients were treated with either ingenol mebutate gel 0.015% once daily for three consecutive days (face/scalp) or ingenol mebutate gel 0...

BACKGROUND: Carbon dioxide therapy, better known as carboxytherapy, relates to percutaneous infusion of medical carbon dioxide with therapeutic approaches, and its use in the treatment of localized fat has demonstrated good results. Gynoid lipodystrophy, also known as cellulite, affects 80%-90% of women after puberty, especially in the buttocks and thighs. Its etiology is complex and involves multifactorial aspects. Its treatment and evaluation require the use of new technologies (more effective and low-cost approaches)...

BACKGROUND: Basal cell carcinoma (BCC) is the most common cancer in Caucasians. Surgical approaches are the most widely used and effective treatment strategies for well-defined BCC. However, for patients with low-risk, superficial BCCs (sBCCs), medical therapy may be a treatment option. In this small case series, we describe our experience in using topical treatment with ingenol mebutate gel, 0.05%, for patients who refused surgical treatment for sBCC. METHODS: We conducted a retrospective chart review of seven patients from our community dermatology practice for whom sBCC was treated with ingenol mebutate...

Central centrifugal cicatricial alopecia (CCCA) is the most common scarring alopecia among African American women. Data about epidemiology, etiology, genetic inheritance, and management are scarce and come from individual reports or small series. CCCA has been associated with hot combing and traumatic hair styling for years; however, studies fail to confirm it as the sole etiologic factor. It has been shown in a small series that CCCA can be inherited in an autosomal dominant fashion, with a partial penetrance and a strong modifying effect of hairstyling and sex...

Atopic dermatitis (AD) is one of the most common skin diseases. Prevalence of AD is highest in childhood. Because of chronicity and often visible lesions, AD may lead to stigmatization and problems with self-perception. However, problems of self-perception and stigmatization in AD children are poorly studied. Literature data on general tendencies of children's development, clinical course, and epidemiologic tendencies of AD in different age groups make it possible to highlight three main periods in the formation of self-perception and stigmatization...

Topical corticosteroids (TCS) are regarded as the mainstay treatment for atopic dermatitis (AD). As AD has a tendency to heal naturally, the long-term efficacy of TCS in AD management should be compared with the outcomes seen in patients with AD not using TCS. However, there are few long-term studies that consider patients with AD not using TCS. We designed a prospective multicenter cohort study to assess the clinical outcomes in patients with AD who did not use TCS for 6 months and then compared our results with an earlier study by Furue et al which considered AD patients using TCS over 6 months...

With the expiration of patent protection for several biologics looming, the production of highly similar therapeutic agents has begun to emerge on the pharmaceutical market. These alternative drugs are referred to as biosimilars. Many anticipate that the introduction of these agents will result in a reduction in health care costs, which may create a more affordable biopharmaceutical market and also improve patient access. In contrast to generics, which are exact copies of their original products, biosimilars are not identical to their reference products...

PURPOSE: Although treatments for alopecia are in high demand, not all treatments are safe and reliable. Dalteparin/protamine nanoparticles (D/P NPs) can effectively carry growth factors (GFs) such as fibroblast GF (FGF)-2. The purpose of this study was to identify the effects of FGF-2-containing D/P NPs (FGF-2&D/P NPs) on hair growth. PATIENTS AND METHODS: In this study, the participants were 12 volunteers with thin hair. One milliliter of FGF-2 (100 ng/mL) and D/P NPs (56 μg/mL) was applied and massaged on the skin of the scalp by the participants twice a day...
