Ultrasound-guided hookwire localization of non palpable cervical lymphadenopathy: A case-control study of operative time.

Objective: We aimed at evaluating the impact of ultrasound-guided (US) hookwire localization of nonpalpable cervical lymphadenopathy on operating time.

Design And Methods: Retrospective case control study (January 2017 and May 2021) of 26 patients with lateral nonpalpable cervical lymphadenopathy undergoing surgery with (H+) and without (H-) per operative US-guided hook-wire localization. Operative time (general anesthesiology onset, hookwire placement, end of surgery) and surgery-related adverse events data were collected.

Mid-term outcomes of mastoid obliteration with biological hydroxyapatite versus bioglass: a radiological and clinical study.

Purpose: Radiological assessment of osseointegration of mastoid grafts: biological hydroxyapatite (Bio-Oss®) (BHA) versus bioglass S53P4 (Bonalive®) (BG).

Methods: Retrospective (10 ± 4 months post-surgery) monocentric high resolution computed tomography (CT) scan assessment (November 2018 and October 2020) by two independent radiologists (R1, R2), blinded to patient allocation. All patients who had undergone a total mastoid obliteration were eligible.

Feasibility of use of medical dual energy scanner for forensic detection and characterization of explosives, a phantom study.

Objective: Detection of explosives is a challenge due to the use of improvised and concealed bombs. Post-bomb strike bodies are handled by emergency and forensic teams. We aimed to determine whether medical dual-energy computed tomography (DECT) algorithm and prediction model can readily detect and distinguish a range of explosives on the human body during disaster victim identification (DVI) processes of bombings.

Post-mortem X-ray computed tomography (PMCT) identification using ante-mortem CT-scan of the sphenoid sinus.

Purpose: To evaluate forensic identification of individuals through visual comparison of sphenoid sinus anatomical configuration using ante- and post-mortem CT-scans.

Method And Materials: Ante- and post-mortem head CT-scan of 33 individuals were retrospectively collected. Ten head CT-scans were randomly selected from various neurological contexts and added to the ante-mortem group.

Central nervous system MRI and cardiac implantable electronic devices.

As the population ages and indications for MRI increase, it is estimated that 50 to 75% of patients with a cardiac implantable electronic device (CIED) - pacemaker (PM) or implanted cardiac defibrillator (ICD) - will need an MRI during their CIED's lifetime. Three categories of materials are defined: MRI compatible, MRI non-compatible, and MRI conditional. MRI compatible CIEDs without electrodes have been developed, but do not allow battery changes, so that they are exclusively indicated for patients whose life expectancy is less than that of the battery (6-7years).
