Introduction The risk of active tuberculosis is increased in psoriasis patients receiving biologic drug therapy. The QuantiFERON-TB Gold In-Tube assay (QFT) is used for latent tuberculosis screening in these patients. This study presents a retrospective analysis on repeated QFT assays, investigating the influence of biologic drugs and isoniazid therapy on the outcome of the assay...
Introduction Androgenetic alopecia (AGA) is the most common cause of hair loss among males, characterized by progressive thinning of the scalp hairs and defined by various patterns. The main factors underling hair loss in AGA are genetic predisposition and increased sensitivity of the hair follicles to androgens, leading to a shortening of the anagen phase. In the present study...
Basal-cell carcinoma is a commonly occurring skin malignancy that has the potential to progress into locally invasive or resistant disease, as well as spread distantly. Due to advances in the molecular understanding of the disease over the last two decades, it has been discovered that the Hedgehog pathway plays an important role in the pathogenesis of this disease and can be...
IntroductionThis study describes a pivotal clinical trial of a new minimally invasive mesotherapy technique for facial rejuvenation.MethodsThe authors utilized two formulations: formulation A with hyaluronic acid, vitamins, amino acids, minerals, coenzymes, and antioxidant substances; formulation B with hyaluronic acid and idebenone. Fifty participants were enrolled in the study...
Introduction Rituximab is increasingly used in patients with pemphigus vulgaris (PV) who are nonresponders to conventional therapy. Methods A PubMed search was conducted using the words pemphigus vulgaris and rituximab therapy from papers published between 2000 and 2012. Two protocols were used. In the lymphoma protocol, patients received four weekly infusions of rituximab (dose...
Introduction Inverse psoriasis is a rare form of psoriasis that affects between 3% and 7% of the patients with psoriasis. It can comprise genital skin folds as part of genital psoriasis, and it is one of the most commonly seen dermatoses of this area. There are few evidence-based studies about the treatment of intertriginous psoriasis involving genital skin folds. Case...
This is a concise review of the uses of botulinum toxins (BTXs) in dermatology and cosmetic procedures. It is a clinical rather than a basic science, pharmacological review. BTX had been initially used for selectively reducing and balancing periorbital muscle activity; thereby, reducing childhood strabismus and blepharospasm. This clinical research was initiated by Dr. Alan Scott...
Introduction In esthetic treatments with dermal fillers, increasing numbers of physicians are using the technique of mixing an anesthetic agent into the dermal filler before treatment to increase the comfort of the patients. This study aimed at evaluating the effects on the physical properties of a polycaprolactone (PCL)-based dermal filler after mixing with lidocaine. Methods A...
Introduction The standard postsurgical treatment of wounds after dermatologic procedures is currently limited. Topical corticosteroids have been used successfully in postoperative management of ophthalmologic surgeries that involve the skin of the eyelid. In particular, tobramycin 0.3%/dexamethasone 0.1% ophthalmic ointment is considered the “gold standard” of steroid-antibiotic...
Introduction Sarcoidosis is a systemic granulomatous disease of unknown cause. The management of sarcoidosis remains problematic. Systemic and topical corticosteroids are the mainstay of therapy but may cause unacceptable side effects. Biologic therapies, such as infliximab, have recently been proposed as another treatment option for cutaneous sarcoidosis. Case Report The authors...
Introduction The objective of this review was to conduct a systematic review with meta-analysis and Bayesian mixed treatment comparisons (MTC) evaluating the impact of biologics on non-Psoriasis Area and Severity Index (PASI) health outcomes in patients with moderate-to-severe plaque psoriasis. Methods MEDLINE and Cochrane Central Register of Controlled Trials were searched from...
Actinic keratoses (AK) are the most common premalignant pathology seen in dermatological practice and represent a burgeoning burden upon health services. Increasingly recognized is the damage to surrounding, perilesional skin, forming the premise for field-directed therapy. Ingenol mebutate gel is a novel agent for field-directed treatment of AK, requiring only 2 or 3 days of...
Background Pyoderma gangrenosum (PG) belongs to a group of neutrophilic dermatoses and is often associated with systemic disorders. The authors present a patient with a recalcitrant PG that did not respond to systemic standard therapies, and discuss further treatment options with impact on quality of life. Case Report A 42-year-old woman with recurrent PG since 2005 was presented...
Autoerythrocyte sensitization syndrome (AES) is a disorder characterized by recurrent, spontaneous, painful bruising in patients with underlying psychosis and neurosis. Its pathogenesis is uncertain. Purpuric lesions reproduced by injections of washed autologous erythrocytes suggest an autoimmune etiology. The authors described a 50-year-old woman who presented with recurrent...
Introduction Clinicians may be confronted with difficult-to-treat psoriasis cases for which there are scant data to rely upon for guidance. To assist in managing such patients, who are typically excluded from clinical trials, a consensus panel of 14 experts in the field of psoriasis was formed to conduct a Delphi method exercise. Methods The exercise consisted of both survey...
Introduction Obinutuzumab (GA101) is a novel anti-CD20 monoclonal antibody that has been shown to be effective for the treatment of non-Hodgkin’s lymphoma, and is currently being evaluated in phase 3 clinical trials. The side-effect profile of the drug is not yet well established. Case report The authors report a case of a 62-year-old patient who developed widespread lichenoid...
Introduction Traditional clinical trials in psoriasis exclude a significant proportion of patients with complex disease and comorbidities. A consensus panel of 14 experts in the field of psoriasis was formed to conduct a Delphi method exercise to identify difficult-to-treat psoriasis clinical scenarios and to rank treatment approaches. Methods The exercise consisted of both...
Psoriasis is an immune-mediated disease that affects 1%–2% of the European and North American population. While topical agents such as corticosteroids and vitamin D derivatives are prescribed for mild disease, they are generally unable to adequately control patients with more severe disease. Over the past decade, research into the immunopathogenesis of psoriasis, including...
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder, with multisystem involvement, including cutaneous manifestations of hyperpigmentation and neurofibromas. Multiple cutaneous lesions are often disfiguring and lead to emotional distress and social isolation. Treatment of NF1 is predominantly surgical but alternative treatments should be considered for patients with...
IntroductionIt is now recognized that to adequately protect skin from sun damage, sunscreens require a photostable combination of ultraviolet (UV) filters with a suitable level of UVA protection. The total amount of UV filters should be as low as possible to avoid adverse skin reactions, potential environmental impact, and to ensure acceptable texture for better application and...
Background Lupoid cutaneous leishmaniasis (CL) is a rare form of CL having a striking resemblance to other granulomatous cutaneous conditions of infectious or inflammatory origin. The authors present a patient with a facial lupoid CL and discuss the diagnostic tools of this parasitological infection, the main differential diagnosis, and treatment. Case report A 54-year-old...
Introduction Nevus lipomatosus cutaneous superficialis (NLCS) is a rare benign hamartomatous skin tumor characterized by dermal deposition of mature adipose tissue. It’s classified in two types: the classical form with multiple soft, pedunculated, cerebriform papules and nodules that coalesce into plaques, and the solitary form that consists of a solitary papule or nodule. In...
