Fluorescence microscopy of parathyroid and thyroid tissues for localization of autofluorescent substances using near-infrared wavelengths.

Objective: The parathyroid gland emits autofluorescence with a peak at 822 nm when excited using near-infrared light at 785 nm; this observation of autofluorescence using a near-infrared detection device is useful for identifying the parathyroid gland during surgery. We aimed to clarify the localization of autofluorescent substances in parathyroid and thyroid tissues by observing them under a fluorescence microscope through filters that selectively pass specific near-infrared wavelengths.

Methods: Four cases of parathyroid and three cases of thyroid were examined under a fluorescence microscope.

Factors Affecting Patients' Acceptance of Switching to Biosimilars Are Disease-Dependent: A Cross-Sectional Study.

Biosimilars (BS) are promoted worldwide because of the high cost of biologics. However, patients are apprehensive about switching to BS. For some diseases, several factors, which may be disease-dependent, influence patients' acceptance of switching to BS.

Droperidol Reduces Postoperative Nausea and Vomiting and Supports the Continuation of Intravenous Patient-Controlled Analgesia with Fentanyl.

Purpose: To examine the impact of adding droperidol to fentanyl-based intravenous patient- controlled analgesia (IVPCA) on the discontinuation of IVPCA use due to postoperative nausea and vomiting (PONV).

Methods: Patients who underwent surgeries other than abdominal surgeries and used IVPCA between April 2014 and March 2018 were selected. Patients using IVPCA with fentanyl alone were compared to patients using droperidol added to IVPCA.
