ABSTRACT
OBJECTIVE: The objectives of this study were to delineate the pro and anti-inflammatory cytokine profiles of psoriasis and cytokine profile models that externally validate the diagnosis. SUBJECTS AND METHODS: This study recruited 70 patients with psoriasis and 76 healthy controls. Cytokine profiles were evaluated, including pro-inflammatory M1 (IL-1 + IL-6 + TNF-α), Th1 (IL-2 + IL-12 + IFN-γ), Th17 (IL-6 + IL-17), and immune-inflammatory response system (IRS = M1 + Th1 + Th17) profiles. Moreover, the anti-inflammatory potential included Th2 (IL-4), Th2 + T regulatory (Th2 + Treg, namely IL-4 + IL-10 + TGF-ß), anti-inflammatory (Th2 + Treg + adiponectin), and the pro-inflammatory/anti-inflammatory index. RESULTS: There was a highly significant association between psoriasis and cytokine levels with an effect size of 0.829 and a particularly strong impact on IL-2 (0.463), IL-12 (0.451), IL-10 (0.532) and adiponectin (0.401). TGF-ß and adiponectin were significantly lower while all other cytokines (except IFN-γ) were significantly higher in psoriasis than in controls. In addition, M1, Th1, Th17, Th2 + Treg, and IRS/Anti-inflammatory index were significantly higher in psoriasis patients than in controls. The IRS index, Th2 + Treg, and adiponectin predicted psoriasis with 97.1% sensitivity and 94% specificity. CONCLUSION: In conclusion, psoriasis is characterized by increased M1, Th1, Th2 and Th17 profiles together with lowered TGF-ß and adiponectin. In addition, we propose a model based on a higher IRS and Th2 + Treg index coupled with lower adiponectin values, which may be used to externally validate the diagnosis of psoriasis. The most important single biomarker of psoriasis is adiponectin. Because the latter may play a role in the modulation of the chronic inflammatory response in psoriasis, adiponectin could be a new drug target to treat psoriasis.

Impetigo herpetiformis is a rare dermatosis of pregnancy with typical onset during the last trimester of pregnancy and rapid resolution in the postpartum period. Clinically and histologically, it is consistent with pustular psoriasis. This similarity has led some authors to name the disease "the pustular psoriasis of pregnancy". We report the case of a patient who developed impetigo herpetiformis in two successive pregnancies.

Impetigo herpetiforme é uma dermatose gestacional rara que se inicia tipicamente durante o último trimestre e evolui com rápida resolução no período pós-parto. Clinica e histologicamente é consistente com psoríase pustulosa. Essa similaridade tem levado alguns autores a nomearem a doença como "psoríase pustulosa da gestação". Relatamos o caso de uma paciente que apresentou impetigo herpetiforme em duas gestações subsequentes.

Noonan Syndrome is one of the most common genetic syndromes and also an important differential diagnosis in children presenting with syndromic facies similar to Turner's syndrome phenotype. This syndrome is characterized by facial dysmorphism, congenital heart defects, short stature and also a wide phenotypic variation. This article discusses the case of a 10 year-old patient with Noonan syndrome that presented typical facies, cardiac defects (pulmonary dilatation and mitral regurgitation), dental malocclusion, micrognatism, short stature and a certain degree of learning disability.

Síndrome de Noonan é uma das mais frequentes síndromes genéticas e importante diagnóstico diferencial em crianças com fácies sindrômica similar ao fenótipo da síndrome de Turner. É caracterizada por dismorfismo facial, defeitos cardíacos congênitos, baixa estatura e uma ampla variação fenotípica. Esse artigo apresenta um caso de uma paciente de 10 anos de idade com síndrome de Noonan que apresentava fácies tiípica além de defeitos cardíacos (dilatação de artéria pulmonar e insufiência mitral), má oclusão dentária, micrognatismo, baixa estatura e dificuldade de aprendizado.
