Wireless continuous single-lead ST-segment monitoring to detect new-onset myocardial injury at the general ward-An exploratory subanalysis.

Patients admitted for acute medical conditions and major noncardiac surgery are at risk of myocardial injury. This is frequently asymptomatic, especially in the context of concomitant pain and analgesics, and detection thus relies on cardiac biomarkers. Continuous single-lead ST-segment monitoring from wireless electrocardiogram (ECG) may enable more timely intervention, but criteria for alerts need to be defined to reduce false alerts.

FDG-PET/CT in the surveillance of head and neck cancer following radiotherapy.

Purpose: To examine the time-dependent diagnostic performance of FDG-PET/CT in the follow-up of head and neck cancer (HNC) and to assess the prognostic value of PET-negative and PET-inconclusive findings.

Material And Methods: 279 HNC patients primarily treated with radiotherapy from 2006 to 2012 were included. The follow-up PET/CT scans were categorized as benign, malignant or inconclusive by a radiologist and a nuclear physician.

The Influence of Volume and Anatomic Location of Optic Disc Drusen on the Sensitivity of Autofluorescence.

Background: Optic disc drusen (ODD) are acellular deposits in the optic nerve head. ODD can be diagnosed using different imaging modalities, including enhanced depth imaging optical coherence tomography (EDI-OCT) and autofluorescence (AF). It is unknown which factors determine the sensitivity of AF.
