Spatial analysis of photoplethysmography in cutaneous squamous cell carcinoma.

The primary treatment of the common malignancy squamous cell carcinoma is surgical removal. In this process, sufficient tissue removal is balanced against unnecessary mutilation. We recently presented a remote photoplethysmography algorithm, which revealed significant differences between processed video recordings of cancer biopsy areas and surrounding tissue.

Photoplethysmography for demarcation of cutaneous squamous cell carcinoma.

A video processing algorithm designed to identify cancer suspicious skin areas is presented here. It is based on video recordings of squamous cell carcinoma in the skin. Squamous cell carcinoma is a common malignancy, normally treated by surgical removal.

[Objective tinnitus].

Objective tinnitus is a known but rare otologic symptom. This is a case report about a six-year-old boy, who was referred to a hearing clinic for further investigation of an audible clicking sound. He experienced clicking sounds, and his parents were able to hear the sounds when listening nearby.
