Intraosseous ganglion (IOG) is the most frequently occurring bone lesion within the carpus and is often an incidental finding on radiographs obtained for other reasons. Two types of IOG have been described: an "idiopathic" form (or type I), the pathogenesis of which has not been completely clarified, and a "penetrating" form (or type II), caused by the intrusion of juxtacortical material (often a ganglion cyst of the dorsal soft tissue) into the cancellous bone compartment. The differential diagnosis for IOG is wide-ranging and complex, including lesions of posttraumatic (posttraumatic cystlike defects), degenerative (subchondral degenerative cysts), inflammatory [cystic rheumatoid arthritis, chronic tophaceous gout (CTG)], neoplastic (benign primary bone tumours and synovial proliferative lesions), ischaemic (Kienböck's disease or avascular osteonecrosis of the lunate) and metabolic (amyloidosis) origin. Multimodality imaging of IOGs is a useful diagnostic tool that provides complete morphological characterisation and differentiation from other intraosseous cystic abnormalities of the carpus. Thin-slice multidetector computed tomography (MDCT) can provide high-spatial-resolution images of the cortical and cancellous bone compartments, allowing detection of morphological findings helpful in characterising bone lesions, whereas magnetic resonance (MR) imaging can simultaneously visualise bone, articular surfaces, hyaline cartilage, fibrocartilage, capsules and ligaments, along with intra- and periarticular soft tissues.

The wide range of mass spectrometry imaging (MSI) technologies enables the spatial distributions of many analyte classes to be investigated. However, as each approach is best suited to certain analytes, combinations of different MSI techniques are increasingly being explored to obtain more chemical information from a sample. In many cases, performing a sequential analysis of the same tissue section is ideal to enable a direct correlation of multimodal data.

Effective team science requires procedural harmonization for rigor and reproducibility. Multicenter studies across experimental modalities (domains) can help accelerate translation. The Translational Outcomes Project in NeuroTrauma (TOP-NT) is a pre-clinical traumatic brain injury (TBI) consortium charged with establishing and validating noninvasive TBI assessment tools through team science.

Predictive Factors of a Dominant Superficial Venous Drainage System in DIEP Flap Surgery With Preoperative Computed Tomography Angiography.

Microsurgery

January 2025

Service de Chirurgie Plastique, Hôpital Européen Georges Pompidou, Assistance Publique-Hôpitaux de Paris (APHP), Université Paris Descartes, Paris, France.

Background: Venous congestion due to superficial venous system dominance (SVD) in deep inferior epigastric perforator (DIEP) flap surgery occurs in approximately 2% of cases, with attendant sequelae and increased cost to healthcare systems. This study aimed to describe the predictive factors for SVD in DIEP flap breast reconstruction based on preoperative computed tomography angiography (CTA) findings.

Methods: All women who required takebacks for additional venous anastomosis to the cephalic vein because of SVD after DIEP flap breast reconstruction between 2015 and 2022 were included.

Objective: To investigate the structural damage in patients with aphasia in the acute phase of ischemic stroke using X-ray computed tomography (CT) scans of the brain.

Material And Methods: We examined 65 right-handed individuals in the acute stage of ischemic stroke in the left middle cerebral artery, including 39 men and 26 women aged 41 to 87 years. The patients were divided into two groups: those with aphasia (group 1, 48) and those without aphasia (group 2, 17).

Background: Small-cell lung cancer (SCLC) is highly malignant. Despite being highly sensitive to initial chemotherapy and radiotherapy, the recurrence rate is high. Atezolizumab is the first immune checkpoint inhibitor (ICI) that has been proven to provide an overall survival (OS) benefit for extensive-stage SCLC (ES-SCLC), making ICIs in combination with chemotherapy the standard first-line treatment for ES-SCLC.
