Infections in Moderate to Severe Psoriasis Patients Treated with Biological Drugs Compared to Classic Systemic Drugs: Findings from the BIOBADADERM Registry.

Information regarding the safety of biological drugs prescribed to psoriasis patients on daily and long-term bases is insufficient. We used data from the BIOBADADERM registry (Spanish Registry of Adverse Events for Biological Therapy in Dermatological Diseases) to generate crude rates of infection during therapy with systemic drugs, including biological drugs (infliximab, etanercept, adalimumab, and ustekinumab) and nonbiological drugs (acitretin, cyclosporine, and methotrexate). We also calculated unadjusted and adjusted risk ratios (RRs) (with propensity score adjustment) of infection, serious infections, and recurrent infections of systemic therapies compared with methotrexate, using Poisson regression.

Long-Term Cost-Effectiveness Analysis of Etanercept and Adalimumab for Plaque Psoriasis not Associated with Arthritis.

Introduction: Pharmacoeconomic studies examining the cost-effectiveness of biological agents to treat moderate-to-severe psoriasis in real-life clinical practice are scarce. The aim of this study was to assess the efficiency, in terms of incremental cost-effectiveness, of etanercept and adalimumab in a real clinical setting.

Methods: Direct and indirect costs were assessed from a Spanish societal perspective in a historical hospital cohort of patients with moderate-to-severe psoriasis attending a tertiary referral hospital over a 1-year period.

Therapeutic Hotline: Topical glycopyrrolate: a successful treatment for craniofacial hyperhidrosis and eccrine hidrocystomas.

Eccrine hidrocystoma is a benign tumor derived from eccrine sudoriparous glands. Most eccrine hidrocystomas are solitary and asymptomatic lesions. Multiple hidrocystomas are unusual and have been associated with Graves' disease, Parkinson's disease, and idiopathic craniofacial hyperhidrosis.

Extensive tinea in a patient with severe combined immunodeficiency.

Severe combined immunodeficiency (SCID) is a heterogeneous group of disorders characterized by a defect of T and B cell immunity with a genetic origin in most cases. Although the X-linked recessive form is most common (60-70%), there are autosomal recessive forms (20%) and spontaneous mutations. While SCID may present with many nosocomial infections, dermatophyte infections are not common.

LEOPARD syndrome: what are café noir spots?

Lentigines, electrocardiographic abnormalities, ocular hypertelorism, pulmonary stenosis, abnormalities of genitalia, retarded growth, and deafness syndrome (multiple lentigines syndrome) is most often characterized by multiple lentigines and cardiac conduction defects. Café noir spot is a term proposed, by analogy to café au lait spots, for the larger and darkly pigmented patches that are frequently observed in patients with this syndrome. Although presumed by some authors to represent lentigines, the histologic features of café noir spots have not been well documented in the literature.

[Angiosarcoma in chronic lymphedema].

Angiosarcoma that develops on a limb with chronic lymphedema is called Stewart-Treves syndrome. This typically appears as a complication of a long course lymphedema located on the arm, after mastectomy and/or radiotherapy due to breast cancer. There are cases of Stewart-Treves syndrome in chronic lymphedema in the upper limb contralateral to the breast treated for cancer and in chronic lymphedema of the leg.

[Diffuse cutaneous reticulohistiocytosis].

The reticulohistiocytoses make up a heterogeneous group of diseases whose origin lies in an accumulation of cells of histiocytic lineage in different tissues and primarily in the skin. Three main clinical forms have been described (multicentric, solitary, diffuse cutaneous), which present with identical histological, ultrastructural and immunohistochemical characteristics. We present a case of diffuse cutaneous reticulohistiocytosis, which is the least common clinical pattern in the spectrum of this disease.

[Treatment of chronic ulcers].

Chronic ulcers are a challenge in dermatological therapy. It is essential to establish their etiology in order to treat them, but on many occasions local therapy is of great interest. Treatment of chronic ulcers is currently based on so-called moist wound healing, and it takes two aspects into consideration: the underlying pathology and local treatment.

[Neutrophilic eccrine hidradenitis secondary to thioguanine in a neutropenic patient].

Neutrophilic eccrine hidradenitis (NEH) is an infrequent, self-limited inflammatory dermatosis characterized by a neutrophilic infiltrate around the eccrine glands. Clinically, it presents with different types of lesions. NEH occurs most frequently in patients who have undergone chemotherapy for hematologic neoplasms.
