ABSTRACT
There is limited information available on pressure-related neonatal nasal injuries. We present three neonates born with erythema and purpura of the nasal tip that subsequently ulcerated, then evolved into a thick eschar. Each healed well with conservative management but left behind significant scarring. The sharp demarcation and location of the lesions were suggestive of hypoxic tissue damage akin to halo scalp ring alopecia. Further investigation is necessary to elucidate the etiology and optimal management of this condition.
ABSTRACT
BACKGROUND: COVID-19, the widely recognized and highly contagious respiratory tract infection, has had a substantial impact on the field of dermatology since its emergence in 2019. SARS-CoV-2, the causative virus of COVID-19, is classified as an RNA virus. Various skin-related symptoms have been reported in patients with COVID-19, most notably the distinctive purple-red acral rash resembling chilblain lesions, commonly referred to as 'COVID toe'; similarly, skin-related symptoms have been observed in connection with other RNA viruses. OBJECTIVES: To explore the relationship between RNA viruses and their associated vascular cutaneous manifestations vs. those observed in patients infected with SARS-CoV-2. METHODS: A systematic literature review was conducted using PubMed and medical subject heading terms related to RNA viruses and related skin manifestations. RESULTS: In total, 3994 patients diagnosed with COVID-19 presenting with skin rashes were included. Chilblain-like lesions were most frequently observed (30.2%), followed by erythematous maculopapular/morbilliform rashes (9.1%) and urticarial rashes (4.7%). Of 8362 patients diagnosed with RNA viruses, more than half of the skin findings reported were erythematous/maculopapular/morbilliform rashes (52.3%), followed by unspecified (11.3%) and purpuric rashes (10.6%). CONCLUSIONS: When comparing RNA viral infections with COVID-19 infection, we observed similarities in the reported skin manifestations and their presumed pathways, with many implicated in the proinflammatory response. Owing to the wide range of cutaneous symptoms associated with RNA viruses and our currently limited understanding of the underlying mechanisms, additional research is warranted to investigate the pathology behind viral-induced skin lesions.

In this Part 2 of a 2-part continuing medical education series, we review the epidemiology of peripheral vascular disease, its association with cutaneous symptoms, and the diagnosis and evaluation of cutaneous features of vascular disorders. As peripheral vascular disease becomes more prevalent globally, it is essential for dermatologists to become competent at accurately recognizing and diagnosing cutaneous manifestations and directing individuals to receive appropriate care and treatment.

In this part 1 of a 2-part continuing medical education series, we review the epidemiology and pathophysiology of cardiovascular disease, its association with cutaneous symptoms, and the diagnosis and evaluation of cutaneous features of cardiovascular syndromes, including infective endocarditis, acute rheumatic fever, Kawasaki disease, cholesterol embolization syndrome, lipid disorders, cardiac amyloidosis, and cardiac myxomas. As the incidence and prevalence of cardiovascular diseases increase, dermatologists play an essential role in recognizing the cutaneous manifestations of cardiovascular diseases in order to appropriately connect patients with follow-up care.
