[Ophthalmic oncology in a warmer world: climate-related increase in the prevalence of eyelid cancer].

Background: Damage induced by ultraviolet (UV) radiation plays a decisive role in the carcinogenesis of malignant tumors of the eyelids.

Methods: A selective literature search was performed in PubMed and Google Scholar.

Results: Large epidemiological studies show an increase in the prevalence of eyelid tumors in recent decades.

Radical formation in skin and preclinical characterization of a novel medical plasma device for dermatology after single application.

Cold atmospheric plasma (CAP) enables painless tissue treatment by producing reactive species including excited molecules and charged particles and is of great interest for medical applications. Medical CAP sources work in contact with air at ambient pressure, resulting in the generation of substantial amounts of reactive oxygen and nitrogen radicals. These radicals have a significant influence on cellular biochemistry, are crucial components of the immune system, and play a central role in wound therapy.

In vivo Raman spectroscopic and fluorescence study of suspected melanocytic lesions and surrounding healthy skin.

Cutaneous melanoma is the most lethal skin cancer and noninvasively distinguishing it from benign tumor is a major challenge. Raman spectroscopic measurements were conducted on 65 suspected melanocytic lesions and surrounding healthy skin from 47 patients. Compared to the spectra of healthy skin, spectra of melanocytic lesions exhibited lower intensities in carotenoid bands and higher intensities in lipid and melanin bands, suggesting similar variations in the content of these components.

Reactive Species Risk Assessment Using Optimized HET-CAM Safety Evaluation of Feed Gas-Modified Gas Plasma Technology and Anticancer Drugs.

Clinical therapies, including dermatology and oncology, require safe application. In vitro experiments allow only limited conclusions about in vivo effects, while animal studies in, e.g.

Higher intraoperative detection rate of suspicious non-palpable lesions using wire marking in skin cancer patients.

Background: Follow-up protocols in patients after complete resection of high-risk cutaneous tumors lead to a discovery of metastases in very early stages, but surgery on non-palpable lesions proves to be challenging.

Patients And Methods: In this monocenter retrospective study 39 patients suffering from malignant skin tumors with suspicious non-palpable lesions located in the lymph nodes (90%) or deep subcutaneously/intramuscularly (10%) were included. In 21 patients the lesions were excised under ultrasound guidance, and 18 patients received a wire marking before surgery.
