Diffuse Melanosis Cutis Under Immuno‐ and Targeted Therapy

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT In patients with highly advanced melanoma, rarely a diffuse melanosis cutis (DMC) can be noticed. Even though the condition is generally harmless itself, it can have a significant impact on the patient's well‐being as an obvious mark of the disease. DMC causes a grey or brown discoloration of the skin and mucous membranes. We report on a young

Gold Laser Cricopharyngeal Myectomy for Cricopharyngeal Dysfunction

open access: yesThe Laryngoscope, EarlyView.
Endoscopic treatment for cricopharyngeal bar with or without diverticulum has become the preferred option in management. However, critics cite high recurrence rates. This study evaluated a modified endoscopic approach of cricopharyngeal myectomy, removing a block of tissue with a Gold laser, to treat 84 patients with CP bar, demonstrating significantly

Simultaneous Photoacoustic and Laser‐Induced Ultrasound Imaging of Animals and Humans via a Semi‐Transparent Ultrasound Transducer

open access: yesLaser &Photonics Reviews, EarlyView.
Combined photoacoustic (PA) and ultrasound (US) imaging commonly requires an external pulser to transmit US waves, making systems relatively complicated and suboptimal. Here simultaneous PA and laser‐induced US imaging is demonstrated without using a US pulser. A semi‐transparent ultrasound transducer converts some portion of excitation laser energy to
