Introduction: Psoriasis (PsO), a chronic inflammatory, multisystemic, and multifactorial disease can cause endothelial dysfunction, artery calcification, and atherosclerotic disease. A higher incidence of vascular occlusive events has been observed in psoriatic patients compared to healthy controls, and multiple studies confirm the association between moderate-severe PsO and atherosclerosis, coronary artery calcification, and higher cardiovascular risk., Objective: We sought to analyze atherosclerotic disease prevalence in epiaortic vessels of psoriatic and non-psoriatic patients to understand if PsO could represent an independent risk factor predisposing to atherosclerotic disease., Methods: We evaluated 47 psoriatic patients without cardiovascular risk factors with color Doppler ultrasound (CDUS). If atheromatous plaques were detected, a computed tomography angiography (CTA) was performed. We evaluated 47 non-psoriatic patients without cardiovascular risk factors with CDUS. Atherosclerosis prevalence in both groups were statistically analyzed. CDUS performance was compared to CTA., Results: In the psoriatic group (mean age 50.9 years), 6 had atheromatous plaques and 12 had an intima-media thickness (IMT) > 1 mm (overall prevalence of atherosclerotic disease: 38.2%). All plaques detected with CDUS were confirmed at CTA. In the control group (mean age 51.3 years), CDUS revealed atheromatous plaques in 4 patients and IMT > 1 mm in 4 ones (overall prevalence of 17%). The difference of atherosclerotic disease prevalence between the groups was statistically significant (P < 0.05)., Conclusion: Our results highlight that PsO could be considered a predisposing factor for atherosclerotic disease development in epiaortic vessels, as it causes an increased IMT, that is also considered an independent cardiovascular risk factor., Competing Interests: Competing interests: None., (©2022 Dattola et al.)

Background: Yellow nail syndrome is a rare condition characterized by typical nail alterations and variable presence of lymphedema and respiratory disease. The pathogenesis is still obscure, with most of the literature deriving from case reports and few investigations. The most reported respiratory conditions associated with yellow nail syndrome are pleural effusion and bronchiectasis, whereas association with rhinosinusitis is rarer., Objectives: To describe a case of yellow nail syndrome and to provide a literature review regarding this disorder, discussing pathogenetic hypothesis, associated conditions, and therapeutic options., Patients/methods: A 49-year-old man presented with arrested growth and alterations of his nails, without any history of previous trauma or inflammation but with a severe nasal septum deviation and a history of chronic rhinosinusitis. A diagnosis of yellow nail syndrome was made., Results: Six months after undergoing rhinoseptoplasty and treatment with oral vitamin E, the patient's nails were cured., Conclusions: This case emphasizes the role of the dermatologist in detecting systemic conditions. The correct diagnosis led to complete resolution of both nail alterations and associated respiratory disorders., Competing Interests: Competing interests: The authors have no conflicts of interest to disclose., (©2020 Vollono et al.)
