Plant-Derived Epi-Nutraceuticals as Potential Broad-Spectrum Anti-Viral Agents.

Although the COVID-19 pandemic appears to be diminishing, the emergence of SARS-CoV-2 variants represents a threat to humans due to their inherent transmissibility, immunological evasion, virulence, and invulnerability to existing therapies. The COVID-19 pandemic affected more than 500 million people and caused over 6 million deaths. Vaccines are essential, but in circumstances in which vaccination is not accessible or in individuals with compromised immune systems, drugs can provide additional protection.

Renal cell carcinoma diagnosed by cutaneous metastasis: a case report.

Renal cell carcinoma (RCC) is one of the most frequent malignancies of the genitourinary tract and has the poorest prognosis of all urologic tumors. It often causes metastatic lesions, and although rare, the skin also can be involved. Cutaneous lesions rarely are the primary signs of RCC.

Wells Syndrome with Multiorgan Involvement Mimicking Hypereosinophilic Syndrome.

Eosinophil-associated diseases represent a spectrum of heterogeneous disorders, where blood and cutaneous eosinophilia is the most important feature and eosinophils are the principal cause of cutaneous lesions. These diseases show some similarities in the clinical features but also many distinctive characteristics [Saurat et al., Dermatologia e malattie sessualmente trasmesse, Milano, Masson, 2000].

Isolated oral erosions: an unusual manifestation of secondary syphilis.

The oral cavity is the most common extragenital site of infection. We report a case of a 50-year-old female with isolated oral ulceration as the presenting manifestation of secondary syphilis. In contrast with the oral lesions of primary syphilis, which tend to be solitary, painless, indurated ulcers, oral lesions of secondary syphilis are typically painful, multiple, and accompanied by a concomitant cutaneous eruption.
