Importance: Each year, cellulitis leads to 650 000 hospital admissions and is estimated to cost $3.7 billion in the United States. Previous literature has demonstrated a high misdiagnosis rate for cellulitis, which results in unnecessary antibiotic use and health care cost. Objective: To determine whether dermatologic consultation decreases duration of hospital stay or intravenous antibiotic treatment duration in patients with cellulitis. Design, Setting, and Participants: This randomized clinical trial was conducted in a large urban tertiary care hospital between October 2012 and January 2017, with 1-month follow-up duration...

Schamberg's disease is one of the pigmented purpuric dermatoses (PPD). PPD encompass a large and heterogeneous group of dermatologic disorders featuring purpuric lesions often located on the lower limbs. The various forms of PPD are notoriously known to be resistant to treatment. Fractional photothermolysis has been described as a successful and safe method to induce dermal remodeling. We report three patients with Schamberg's disease who were successfully treated with 4 monthly sessions of fractional non-ablative 1540 nm erbium:glass laser, with resolution of their purpuric pigmented rash lasting up to 9 months after the last treatment session...

BACKGROUND: To define treatment benefit, the Patient Benefit Index contains a weighting of patient-relevant treatment goals using the Patient Needs Questionnaire, which includes a 5-point Likert scale ranging from 0 ("not important at all") to 4 ("very important"). These treatment goals have been assigned to five health dimensions. The importance of each dimension can be derived by averaging the importance ratings on the Likert scales of associated treatment goals...

BACKGROUND AND OBJECTIVES: The standard treatment for cutaneous squamous cell carcinoma (cSCC) is wide local excision (WLE). Incomplete tumor excision is associated with increased recurrence rates and mortality risk. Risk factors for positive margins after WLE of cSCC has been examined in only a few studies. We sought to assess the influence of several clinicopathological factors on margin status in the largest cSCC population to date. METHODS: We performed a retrospective review of records at two skin cancer clinics identifying patients with biopsy-proven cSCC who underwent WLE...

A Cline, J L Jorizzo
Methotrexate is a mainstay treatment for autoimmune and inflammatory conditions in the field of Dermatology. However, in some patients, its use is associated with significant side effects and toxicity. Folate supplementation with either folic acid or folinic acid often mitigates side effects and reduces the incidence of systemic toxicity related to methotrexate. Although the value of methotrexate is clear, debate remains about folate supplementation. There is little agreement about the proper dosing or frequency of folate supplementation as many believe that daily folate supplementation can reduce methotrexate efficacy...

During recent decades, the market for peptide-based drugs, including antimicrobial peptides, has vastly extended and evolved. These drugs can be useful in treatment of various types of disorders, e.g., cancer, autoimmune diseases, infections, and non-healing wounds. Although peptides are less immunogenic than other biologic therapeutics, they can still induce immune responses and cause allergies. It is important to evaluate the immunogenic and allergic potential of peptides before they are forwarded to the expensive stages of clinical trials...

INTRODUCTION: Topical immunotherapy is frequently used in the treatment of alopecia areata (AA) although few studies report long-term follow-up. Our goals were to determine the efficacy and the prognostic factors of topical immunotherapy in a large cohort of patients with AA treated in the departments of Dermatology and Venereology of Bergamo, Como and Pavia, from 1978 to January 2016. METHODS: A total of 252 patients with AA were evaluated retrospectively. RESULTS: All our patients developed an allergic reaction to a 2% solution of dinitrochlorobenzene (DNCB) or squaric acid dibutylester (SADBE) or diphenylcyclopropenone (DPCP)...

Acne is a multifactorial and inflammatory disease of pilosebaceous follicles, which affects most adolescents. Recent epidemiological data revealed a difference in adults affected by this disease. Women have a high prevalence and incidence when compared with men, especially after 25 years of age. In contrast to what was initially thought, most of these patients do not present endocrinopathy capable of leading to the development of the lesions. When present, polycystic ovarian syndrome is the main cause. However, in these cases, acne is rarely the only dermatological manifestation; hirsutism and acanthosis nigricans are often present...

A 58-year-old right-handed woman presented to our institution with a 1-month history of polydipsia and polyuria. She had a remote history of neurofibroma excision by dermatology and, on examination, was noted to meet the clinical diagnostic criteria for neurofibromatosis type 1. Laboratory investigations revealed hypernatraemia and elevated serum osmolality, accompanied by reduced urinary osmolality. A subsequent water deprivation test confirmed central diabetes insipidus, which responded to treatment with desmopressin...

Background and aims: The selective removal of tattoos and benign cutaneous pigmented lesions with laser energy evolved rapidly with the development of the nanosecond-domain Q-switched laser (ns-laser). Recently, however, a series of picosecond-domain lasers (ps-lasers) with pulsewidths less than 1 ns has become commercially available, enabling more efficient and faster removal of pigmented lesions in the field of dermatologic laser surgery. Rationale behind the ps-laser: The efficacy of the ns-laser depended on the theory of selective photothermolysis, whereby an extremely short pulse width was delivered less than the thermal relaxation time (TRT) of a target...

BACKGROUND: Immune checkpoint therapy has dramatically changed the landscape of cancer therapy, providing an efficacious and durable therapeutic option for patients with advanced-stage disease. However, dermatologic toxicities are a well-recognized side effect in patients receiving this therapy. A spectrum of immune related adverse events (irAEs) involving the skin can occur and include immunobullous disorders, lichenoid dermatitis, and vitiligo. Granulomatous/sarcoid-like lesions are now being recognized with the current class of checkpoint inhibitors (CPIs) that involve the dermis, the subcutaneous tissue (panniculitis), and lymph nodes...
