Use of Indocyanine Green Near-Infrared Imaging for Sentinel Lymph Node Biopsy in Early Oral Squamous Cell Carcinoma: A Pilot Study.

Purpose: The current established technique for sentinel lymph node (SLN) biopsy is preoperative injection of technetium-labeled nanosized colloids (Tc) followed by single photon emission computed tomography and standard computed tomography (SPECT/CT) with subsequent intraoperative gamma probe-guided excision of the SLN. It is however time and resource consuming, causes radiation exposure and morbidity for the patient as the injection is done in the awake patient. Recently near-infrared imaging with indocyanine green (ICG) gained importance in SLN biopsy as a faster and more convenient technique.

[Role of computed tomography in the preoperative diagnosis of otosclerosis].

Background: Otosclerosis is an osteodystrophy of the otic capsule and presents with progressive conductive hearing loss. Imaging studies, especially computed tomography (CT) and cone-beam CT, have gained increased relevance in the diagnosis of otosclerosis.

Objective: This study investigated whether there is a correlation between the extent of otosclerosis in high-resolution or cone-beam CT and hearing loss in pure-tone audiometry.

Skin Cancer Development in Solid Organ Transplant Recipients in Switzerland (Swiss Transplant Cohort Study).

Importance: Skin cancer, in particular squamous cell carcinoma, is the most frequent malignancy among solid organ transplant recipients with a higher incidence compared to the general population.

Objective: To determine the skin cancer incidence in organ transplant recipients in Switzerland and to assess the impact of immunosuppressants and other risk factors.

Design: Prospective cohort study of solid organ transplant recipients in Switzerland enrolled in the Swiss Transplant Cohort Study from 2008 to 2013.
