Little is known about whether immunosuppressed patients mount the immunological response necessary to ensure tubal occlusion. Theoretical concern for non-occlusion has limited the use of hysteroscopic sterilization in patients on immunosuppressive therapies. The effects of tumor necrosis factor-alpha (TNF-α) blockers and interleukin (IL)-17 inhibitors on contraception and pregnancy for patients with psoriasis are poorly documented. We report a case of pregnancy that ended in miscarriage in a patient treated first with TNF-α and then with IL-17 inhibitors for severe psoriasis after tubal sterilization with micro-inserts...

INTRODUCTION: Medical device repairing emollient creams (MDRECs) are designed to repair and protect the skin barrier. In this study, we examined the added clinical benefit and tolerability of a MDREC when used in association with a moderately potent topical corticosteroid (TCS) for adults with atopic dermatitis (AD). METHODS: This was an intra-individual randomized controlled trial in adults with moderate to severe AD (EudraCT no. 2014-002,194-10). Symmetrical lesions on each arm of the subjects were randomized to treatment for 10 days with twice-daily TCS (desonide) cream alone or with combined TCS + MDREC...

INTRODUCTION: Reduced number and activities of epidermal stem cells are related to the features of photoaged skin. It was reported that conditioned media from various stem cell cultures are capable of improving the signs of cutaneous aging. This work was performed to establish epidermal progenitor cells derived from mesenchymal stem cells, and to evaluate the anti-aging efficacy of its conditioned media. METHODS: Epidermal progenitor cell culture was established by differentiation from mesenchymal stem cells, and its conditioned medium (EPC-CM) was prepared...

INTRODUCTION: A major clinical challenge in treating allergic contact dermatitis (ACD) is that the first line of treatment is based on the use of corticosteroids. In this study, we aimed to develop a formulation that is devoid of steroids. METHODS: We used mouse ears treated with dinitrofluorobenzene (DNFB) to induce ACD. The efficacy of the test formulation to ameliorate and to prevent induced ACD was determined. RESULTS: To treat this experimentally induced ACD, we developed a formulation containing BIPxine (a mixture of Rosa moschata and Croton lechleri (antioxidants) and Aloe vera and D-panthenol (moisturizers), and hydroglycolic solutions of disodium cromoglycate...

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)...

INTRODUCTION: Few studies have described chronic idiopathic/spontaneous urticaria (CIU/CSU) healthcare burden in adults, while this information remains largely unknown in children. We aimed to describe treatment patterns, healthcare resource utilization (HRU), and costs in CIU/CSU pediatric patients, as well as to compare HRU and costs in CIU/CSU and CIU/CSU-free pediatric patients. METHODS: Medicaid claims from four states (09/01/2013-03/31/2016) were used to identify patients less than 12 years old...

Inflammatory skin diseases are difficult to treat because of a lack of available treatment options for severe disease. However, recent advances have shown that vagus nerve stimulation can be used to decrease inflammation and reduce disease severity in rheumatoid arthritis and inflammatory bowel disease. Changes in cytokine profiles observed in these studies are similar to those seen with use of biologics in inflammatory skin disease, suggesting that they act along similar pathways to disrupt chronic inflammation and treat inflammatory disease...

Skin aging is continuously influenced by various internal and external factors such as the biologic progression of cells, ultraviolet (UV) radiation, tobacco, nutritional deficiencies, and hormonal imbalances that lead to the degradation of skin cells. Through the degradation of skin cells, free radicals and inflammation weaken repair mechanisms and result in collagen and elastic fiber breakdown. The appearance of aging skin is highlighted by skin roughness, wrinkling, pigmentation change, telangiectasias, loss of elasticity, and decreased firmness, all of which are accelerated by these internal and external factors...

INTRODUCTION: Secukinumab, a fully human monoclonal antibody that selectively neutralizes IL-17A, has been shown to have significant efficacy in the treatment of moderate to severe plaque psoriasis (PsO) and psoriatic arthritis (PsA), demonstrating a rapid onset of action and sustained responses with a favorable safety profile. All biotherapeutics, including monoclonal antibodies (mAbs), can be immunogenic, leading to formation of anti-drug antibodies (ADAs) that can result in loss of response and adverse events such as hypersensitivity reactions...

INTRODUCTION: Few studies have evaluated the efficacy of intralesional bleomycin injection combined with electroporation for the treatment of cutaneous tumors. However, the phenomenon that electroporation can enhance the cytotoxicity of bleomycin in vivo by 300-700 fold has been intensely investigated. CASE PRESENTATION: Keratoacanthoma in an 86-year-old patient was treated with intralesional bleomycin combined with electroporation. Treatment consisted of local application of shorty and intense electric pulses followed by local injection of bleomycin...

INTRODUCTION: The incidence of actinic keratosis (AK) continues to increase worldwide. Currently available options for the treatment of AK include topical 5-fluorouracil (5-FU) and daylight-mediated photodynamic therapy (DL-PDT). This split-face pilot study compared DL-PDT using 16% methyl aminolevulinate (MAL) cream versus 5-FU cream in patients with AK on the face/scalp. METHODS: Five male subjects (mean age 70 years) with grade I-III AK on the face/scalp were enrolled...

INTRODUCTION: Phototherapy is the cornerstone of treatment of vitiligo. The 308-nm excimer lamp (EL) induces T cell apoptosis and the stimulation of melanocyte proliferation. Khellin is a furanochromone with a chemical structure close to psoralens. The objective of the study was to evaluate the safety and efficacy of 1-year treatment of recalcitrant vitiligo with a combination of 308-nm EL and khellin. METHODS: Twenty patients with resistant vitiligo were included...

The term "parrot beak nail" describes a morphologic change of the nail plate characterized by excessive forward curvature. It may be associated with systemic disease or, most commonly, occurs as an idiopathic finding complicated by delayed nail plate trimming. The characteristics of parrot beak nails in ten men are described, and the features of this acquired nail deformity are reviewed. Of the ten patients, six presented with concurrent neuropathies that resulted in frequent foot injuries or falls. While the true incidence of parrot beak nails is unknown, this nail deformity occurred in 2...

INTRODUCTION: The negative impact of acne on aspects of health-related quality of life (HRQL) has been demonstrated in many quantitative studies; however, there has been relatively little qualitative research exploring the impact of acne and the use of topical treatment. The study aimed to explore the impact of moderate-severe acne on HRQL in adolescents and adults with inflammatory and non-inflammatory lesions and to develop a conceptual model to illustrate the impact. In addition, the study aimed to identify the attributes of topical acne treatments that are most important for patients...

Eosinophilic annular erythema (EAE) is a rare entity of unknown etiology that is possibly related to a hypersensitivity reaction and presents as annular erythematous plaques with tissue eosinophilia. It is classified as a figurate erythema with a controversial relationship to Wells syndrome (WS) in the literature, where it is generally considered a separate entity or subset based on clinical and histopathologic differences. EAE typically presents with recurrent, erythematous, arcuate, and annular plaques on the trunk and proximal extremities...

INTRODUCTION: Pentostatin (2'-deoxycoformycin) and cladribine (2-chlorodeoxyadenosine) are adenosine analogues widely used to treat lymphoid malignancies, mainly hairy cell leukemia (HCL). Oral or parenteral adenosine analogues have been also used as immunomodulatory agents in multiple sclerosis and in acute graft-versus-host disease. CASE REPORT: Here, we report the case of a 43-year-old patient with a history of extensive psoriasis who later developed HCL. RESULTS: The patient had achieved complete remission of both psoriasis and HCL after receiving intravenous infusions of pentostatin...
