Article Synopsis
  • The rise in malignant skin tumors presents a public health challenge, which could be mitigated by improving detection methods.
  • Current diagnoses rely on physician expertise, sometimes leading to misdiagnosis or unnecessary procedures.
  • Innovative non-invasive imaging techniques and AI-based methods show promise in enhancing skin cancer assessment, with specific focus on dermoscopy images and machine learning approaches, though further standardization of methods is needed for better reproducibility.

Article Synopsis
  • Recovery from anesthesia may not just be a simple reversal of the induction process, as recent discussions highlight the concept of "neural inertia," where changes in consciousness could show hysteresis.
  • The study investigated this phenomenon by analyzing propofol concentrations during 46 surgeries, looking specifically at the moments of loss and recovery of responsiveness.
  • Results indicated that there was a significant difference in propofol concentrations between the moments of loss of responsiveness (LOR) and recovery of responsiveness (ROR), supporting the idea of hysteresis in human consciousness recovery during anesthesia.

Purpose: Obstructive sleep apnea syndrome (OSAS) is characterized by upper airway inflammation. The aim of this study was to characterize thermal profile of the antero-cervical region in OSAS patients through medical thermal imaging and to compare the respective subjects with non-OSAS individuals.

Methods: Image capture followed the Glamorgan Protocol.
