Skin manifestations associated with systemic diseases - Part I

Abstract The skin demonstrates what is happening in the body in many diseases, as it reflects some internal processes on the surface. In this sense, skin as an organ, goes beyond its protective and barrier functions, as it provides clues for the identification of some systemic diseases. The dermatologist then raises diagnostic hypotheses for conditions related to all systems and refers them to the appropriate specialty. With easy access to examination by trained eyes and biopsies, the skin can present specific or non specific alterations on histopathology. In the first case this combination establishes the diagnosis of the disease itself. Non specific manifestations can occur in a variety of contexts and then histopathology is not specific of a particular disease. This article is divided into two parts that will cover large groups of diseases. In this first part, cutaneous manifestations of the main rheumatologic diseases are described, which are the ones with the greatest interface with dermatology. The authors also talk about vascular manifestations and granulomatous diseases. In the second part, endocrinological, hematological, oncological, cardiovascular, renal, gastrointestinal diseases, pruritus and its causes are discussed, and finally, the dermatological manifestations of SARS-CoV-2 coronavirus infection. The authors' intention is that, by using direct and easily accessible language, aim to provide practical material for consultation and improvement to all dermatologists who recognize the importance of a comprehensive assessment of their patients.

Diagnostic and therapeutic guidelines for plaque psoriasis - Brazilian Society of Dermatology.

Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

How relevant are vascular endothelial growth factor and intercellular adhesion molecule in the systemic capillary leak syndrome of psoriasis?

Abstract: Psoriasis is a chronic disease, characterized by erythematous scaly lesions, presented in eight different forms: plaques, guttate, pustular, erythrodermic, inverse, nail and scalp psoriasis, and psoriatic arthritis. Its development depends on genetic factors, external stimulus and immune response alteration.1 Proinflammatory cytokines such as TNF-alpha, IL-12 and 23 may also be involved. In the worst cases, systemic complications linked to endothelial alterations may occur. A literature review was conducted for a better understanding of what roles VEGF (vascular endothelial growth factor) and ICAM-1 (intercellular adhesion molecule) have, among other cytokines, in systemic capillary leak syndrome, involved in erythrodermic and pustular psoriasis, the most unstable forms of the disease.

Lichen sclerosus associated with localized scleroderma: dermoscopy contribution.

Lichen sclerosus is an uncommon inflammatory dermatosis with preferential involvement of the urogenital region. The extragenital involvement is uncommon and is characterized by small rounded macules or papules, pearly white in color. The coexistence of lichen sclerosus and scleroderma plaques in most cases with extragenital location has been reported in the literature. We report a case of lichen sclerosus associated with scleroderma in children, highlighting the importance of dermoscopy in diagnosis.

Bullous pemphigoid and neurological disease: statistics from a dermatology service.

Bullous pemphigoid (BP) is an autoimmune, acquired, cutaneous disease caused by the production of autoantibodies against hemidesmosomes' components in the basement membrane. The estimated incidence in Europe ranges from 7 to 43 cases per million inhabitants per year. Several studies have reported an association between BP and neurological disorders (ND). Our cohort of Bullous pemphigoid and ND is the first in Brazil and showed a significantly high prevalence of neurological and/or psychiatric diseases, especially cerebrovascular accident (CVA) and dementia, in agreement with the prevalence reported in several studies published in the medical literature in recent years.

Systemic sarcoidosis induced by etanercept: first Brazilian case report.

The antagonists of tumor necrosis factor alpha (TNF-α) are increasingly being used in the treatment of inflammatory and autoimmune diseases. Several adverse effects of these drugs have been reported, including the paradoxical development of sarcoidosis, especially with the use of etanercept. We present the first Brazilian case report of systemic sarcoidosis induced by etanercept and a literature review.
