Daniel Coelho de Sá, Cyro Festa
Inflammasomes are intracellular multiprotein complexes that comprise part of the innate immune response. Since their definition, inflammasome disorders have been linked to an increasing number of diseases. Autoinflammatory diseases refer to disorders in which local factors lead to the activation of innate immune cells, causing tissue damage when in the absence of autoantigens and autoantibodies. Skin symptoms include the main features of monogenic inflammasomopathies, such as Cryopyrin-Associated Periodic Syndromes (CAPS), Familial Mediterranean Fever (FMF), Schnitzler Syndrome, Hyper-IgD Syndrome (HIDS), PAPA Syndrome, and Deficiency of IL-1 Receptor Antagonist (DIRA)...

Dermatologists frequently employ combination therapy to treat various diseases, but the evidence to support the use of such combinations is often lacking. Synergy is an appealing although somewhat ambiguous concept in medicine. Utilizing synergy allows clinicians to provide the most efficacious combination of treatments to patients, while potentially minimizing adverse effects and reducing the development of drug resistance. Definitions of synergy vary, but ultimately converge on finding a therapeutic advantage in combining treatments...

BACKGROUND: Anti-tumor necrosis factor (TNF) therapy in psoriasis has been associated with an increased risk of serious infections compared with nonbiologic systemic therapies. OBJECTIVE: We sought to quantify the risk of: (1) serious infections (leading to hospitalization, sequelae, or death); and (2) "any infection," bacterial cutaneous infections, and granulomatous infections among patients receiving anti-TNF therapy compared with nonbiologics (acitretin, methotrexate, cyclosporine)...

INTRODUCTION: Treatment goals depend on individual definitions of "treatment success" and tend to differ between patients and physicians. Patients who do not meet their own treatment goals, but do meet provider definitions of well-controlled disease, may be inappropriately placed on stable treatment regimens. METHODS: Patients with psoriasis on stable treatment regimens were queried about perceptions of disease control, improvement level, overall treatment satisfaction, and consideration for trying new treatments...

Porokeratosis is a disorder of epidermal keratinization characterized clinically by a distinctive ridge-like border, and histologically by cornoid lamellae. The known clinical variants of porokeratosis are: classic porokeratosis of Mibelli, disseminated superficial (actinic) porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata, linear porokeratosis and punctate porokeratosis. In 1995, a seventh form was described as porokeratosis ptychotropica: a verrucous form resembling psoriasis involving the gluteal cleft presenting on the histological exam multiple cornoid lamellae...

INTRODUCTION: Papulosquamous diseases are characterized by scaly papules and plaques with similar clinical picture which amounts to confusion and hence, a definitive histopathological diagnosis goes a long way in treatment of such diseases. AIM: The aim of the study was to study the histomorphology of non-infectious, erythaematous, papulosquamous lesions of skin with clinicopathological correlation. MATERIALS AND METHODS: Skin biopsies from 150 clinically diagnosed/suspected non-infectious erythaematous, papulosquamous skin diseases were received in the Department of Pathology...

The extensive involvement of miRNA in the pathophysiology of psoriasis is well-documented. However, in order for this information to be useful towards therapeutic manipulation of miRNA-levels, it is essential that detailed functional mechanisms are elucidated. MiR-125b has previously been shown to be strongly associated with psoriasis, and presents as an obvious candidate for further investigation OBJECTIVES: Elucidate the specific pathway and mechanism of interest in this association METHODS: A three-step bioinformatical hypothesis-generation pipeline was performed to identify genes of interest...

Porokeratosis is defined as a disorder of keratinization characterized by one or more atrophic patches surrounded by a clinically and histologically distinctive hyperkeratotic ridgelike border called the cornoid lamella. Lesions are most commonly located on the sun-exposed sides of trunk and extremities, while exclusive facial involvement has been also reported. Despite that the exact risk of cutaneous malignancy developing in porokeratosis is unknown, it is confirmed by series of case reports, including squamous cell carcinoma, basal cell carcinoma and even melanoma...

Sjögren's syndrome is a chronic autoimmune disease whose main clinical manifestation is oral dryness (xerostomia) and ocular dryness (xerophthalmia). It is characterized by progressive mononuclear infiltration of the exocrine glands and can affect a variety of organ systems. The prevalence of primary Sjögren's syndrome varies from 0.01 up to 4.8%; this variability reflects differences in definition, application of diagnostic criteria, and geographic differences in age groups. The etiology of primary Sjögren's syndrome is unknown, but the interaction between genetic and environmental factors (viruses, hormones, vitamins, stress) is important...

Palmoplantar psoriasis and palmoplantar pustulosis are chronic skin diseases with a large impact on patient quality of life. They are frequently refractory to treatment, being generally described as a therapeutic challenge. This article aims to review the definitions of palmoplantar psoriasis and palmoplantar pustulosis, highlighting the similarities and differences in terms of epidemiology, clinical presentation, genetics, histopathology, and pathogenesis, as well as treatment options for both entities. Classical management of mild to moderate palmoplantar pustulosis and palmoplantar psoriasis relies on use of potent topical corticosteroids, phototherapy, and/or acitretin...

BACKGROUND: Tumor necrosis factor (TNF) antagonists have improved outcomes for patients with psoriasis, but some patients are unresponsive to treatment (primary failure) or lose an initially effective response (secondary failure). OBJECTIVE: We sought to systematically investigate the efficacy and safety of a second TNF antagonist after failure of a first TNF antagonist. METHODS: Published primary studies evaluating the efficacy of switching TNF antagonists after failure were systematically extracted...

Although cutaneous psoriasis is common, the existence of its manifestations in the oral cavity has been questioned. The definitive diagnosis of oral psoriasis can be challenging due to the variability of presentations, and overlapping clinical and histological features with a number of other conditions as well as the lack of consensus. We review oral psoriasis, noting its variable clinical appearance, delineate the differential diagnosis, and discuss management strategies.

There is no standard definition regarding the severity of psoriasis, and a number of factors should be considered, including the extent and stability of skin disease, involvement of joints, response to treatment, and impact on quality of life. Erythrodermic psoriasis and pustular psoriasis are severe conditions and the patient may be systemically unwell and febrile. NICE recommends that four key areas should be evaluated and recorded when assessing patients: severity, using the static Physician's Global Assessment (sPGA); disease impact on physical, psychological and social wellbeing using the Dermatology Life Quality Index (DLQI); the presence of psoriatic arthritis; and comorbidities...

In vivo reflectance confocal microscopy (RCM) is a relatively novel non-invasive tool for microscopic evaluation of the skin used prevalently for diagnosis and management of skin tumour. Its axial resolution, its non-invasive and easy clinical application represents the goals for a large diffusion of this technique. During the last 15 years, RCM has been demonstrated to be able to increase the sensibility and sensitivity of dermoscopy in the diagnosis of skin tumours integrating in real time clinic, dermoscopic and microscopic information useful for the definition of malignancy...

Juvenile idiopathic arthritis (JIA) is a group of diseases defined by the presence of arthritis of more than 6 weeks duration in patients aged less than 16 years and with unknown etiology. The international classification based on clinical and biological criteria define each type of JIA: systemic, oligoarticular, polyarticular with and without rheumatoid factor, enthesitis-related arthritis, and psoriatic arthritis. However, some discussions persist concerning systemic-onset juvenile idiopathic arthritis, whose clinical symptoms and pathogenic mechanisms are quite similar to those observed in autoinflammatory diseases, arthritis with antinuclear factors (poly- and oligoarticular) that could be considered as a homogenous group, and a family history of psoriasis that frequently led to unclassified arthritis...
