Temporary inferior vena cava filters factors associated with non-removal.

Objectives: Inferior vena cava filter (IVCF) placement is indicated when there is a deep vein thrombosis and/or a pulmonary embolism and a contraindication of anticoagulation. Due to the increased risk of recurrent deep venous thrombosis when left in place, IVCF removal is indicated once anticoagulant treatment can be reintroduced. However, many temporary IVCF are not removed.

Combination of Percutaneous Screw Fixation and Cementoplasty for Lytic Bone Metastases: Feasibility, Safety and Clinical Outcomes.

Objective: To evaluate feasibility, safety and efficacy of a combination of screw fixation and cementoplasty for pathologic bone fracture.

Methods: In this single-center prospective study, all consecutive percutaneous screw fixations under assisted CT guidance for palliation and fracture treatment of pathologic bone fracture were reviewed from July 2019 to February 2021. The primary outcome measure was the procedures' technical success, defined as the correct placement of the screw(s), without any complications.

Percutaneous screw fixation and cementoplasty of metastatic sternal fracture: Descriptions of 2 cases.

Secondary lesions and hemopathy localized in sternal bone may be responsible for persistent pain and resistant to classical analgesics. Surgical treatment is not applicable in these cases. We report on 2 cases of sternal osteosynthesis by internal cemented screw fixation, under fluoroscopy and CT scan control, without complication and with clear, immediate reduction of pain.

Safety and efficacy of emergency transarterial embolization for mesenteric bleeding.

Background: Patients with spontaneous or traumatic active mesenteric bleeding cannot be treated endoscopically. Transarterial embolization can serve as a potential alternative to emergency surgery. Literature on transarterial embolization for mesenteric bleeding remains very scarce.

Chordomas: A review with emphasis on their pathophysiology, pathology, molecular biology, and genetics.

Chordomas are uncommon, bone, axial, or (rarely) extra-axial tumors that are malignant and frequently recur but less commonly metastasize. They usually affect adults, with a very small proportion being pediatric tumors. For children, such tumors present a different biology, since they are more common as scull rather than sacral tumors, with aggressive histological features, including a loss of SMARCB1/INI1 and a dismal prognosis.

Boundary and vulnerability estimation of the internal borderzone using ischemic stroke lesion mapping.

Distinction between deep and superficial middle cerebral artery (MCA) territories and their junctional vascular area (the internal borderzone or IBZ) constitutes a predictor of stroke patient outcome. However, the IBZ boundaries are not well-defined because of substantial anatomical variance. Here, we built a statistical estimate of the IBZ and tested its vulnerability to ischemia using an independent sample.

Comparison of cytology, chest computed and positron emission tomography findings in malignant pleural effusion from lung cancer.

Background: Malignant pleural effusion (MPE) is a common medical problem in lung cancer (LC). Pleural fluid cytology (PFC), chest computed tomography (CCT) and positron emission tomography (PET) findings are helpful as first line approach. The objectives of this study were to evaluate whether there is a correlation between PFC, CCT and PET in patients with MPE due to LC.

Supra-Epiglottic Upper Airway Volume in Elderly Patients with Obstructive Sleep Apnea Hypopnea Syndrome.

Objective: Small upper airway measurements areas and high body mass index are recognized risk factors for obstructive sleep apnea syndrome (OSAS) in non-elderly populations; however, there is limited information regarding elderly patients. We evaluated whether upper airway volume is associated with OSAS and OSAS treated with continuous positive airway pressure (CPAP) treatment and whether BMI is correlated with upper airway volume and measurements in elderly subjects.

Methods: In 60 volunteers aged 75.

Incidental findings on brain magnetic resonance imaging in the elderly:the PROOF study.

To prospectively evaluate the prevalence of incidental findings on standardized brain MRI scans in a cohort of elderly subjects. All participants provided written informed consent to participate in this prospective study, which was approved by the institutional review board and was HIPAA compliant. There were 503 subjects (75.

Visual Assessment of Age-Related White Matter Hyperintensities Using FLAIR Images at 3 T: Inter- and Intra-Rater Agreement.

Background: Age-related white matter hyperintensities are frequent incidental findings on T2-weighted brain MRI, and they are evaluated in clinical practice using a visual rating scale.

Objective: To evaluate inter- and intra-rater agreement in MRI visual evaluations of age-related white matter hyperintensities made by two radiologists with different levels of experience using a visual rating scale.

Methods: Two radiologists of two different levels of experience separately rated age-related white matter hyperintensities in 40 consecutive 3-tesla brain MRI scans using the Fazekas and Schmidt visual rating scale.

Effect of a retrievable inferior vena cava filter plus anticoagulation vs anticoagulation alone on risk of recurrent pulmonary embolism: a randomized clinical trial.

Importance: Although retrievable inferior vena cava filters are frequently used in addition to anticoagulation in patients with acute venous thromboembolism, their benefit-risk ratio is unclear.

Objective: To evaluate the efficacy and safety of retrievable vena cava filters plus anticoagulation vs anticoagulation alone for preventing pulmonary embolism recurrence in patients presenting with acute pulmonary embolism and a high risk of recurrence.

Design, Setting, And Participants: Randomized, open-label, blinded end point trial (PREPIC2) with 6-month follow-up conducted from August 2006 to January 2013.

Brain magnetic resonance imaging findings in cryptogenic stroke patients under 60 years with patent foramen ovale.

Purpose: To compare magnetic resonance imaging (MRI) brain feature in cryptogenic stroke patients with patent foramen ovale (PFO), cryptogenic stroke patients without PFO and patients with cardioembolic stroke.

Materials And Methods: The ethics committee required neither institutional review board approval nor informed patient consent for retrospective analyses of the patients' medical records and imaging data. The patients' medical files were retrospectively reviewed in accordance with human subject research protocols.

The 'where' and the 'when' of the BOLD response to pain in the insular cortex. Discussion on amplitudes and latencies.

The operculo-insular cortex has been recently pointed out to be the main area of the pain matrix to be involved in the integration of pain intensity. This fMRI study specified the pattern of response to laser stimuli by focusing on this cortical area, by optimizing the temporal sampling and by investigating pain-related differences in the amplitudes and latencies of the BOLD responses. Canonical and temporal derivative hemodynamic response function (HRF) and finite impulse response (FIR) modeling provided consistent results.

Spatial segregation of somato-sensory and pain activations in the human operculo-insular cortex.

The role of operculo-insular region in the processing of somato-sensory inputs, painful or not, is now well established. However, available maps from previous literature show a substantial overlap of cortical areas activated by these stimuli, and the region referred to as the "secondary somatosensory area (SII)" is widely distributed in the parietal operculum. Differentiating SII from posterior insula cortex, which is anatomically contiguous, is not easy, explaining why the "operculo-insular" label has been introduced to describe activations by somatosensory stimuli in this cortical region.

Modulation of the default mode network is task-dependant in chronic schizophrenia patients.

The activity of brain regions of the so-called default mode network (DMN) attenuates during the performance of goal-directed tasks. These activity decreases (named task-induced deactivations; TID) are though to reflect the reallocation of cognitive resources from the DMN to areas implicated in the execution of the task. Recently, DMN activity suppression has been studied in schizophrenia patients.

Brain activation during executive processes in schizophrenia.

Schizophrenia patients show some deficits in executive processes (impaired behavioural performance and abnormal brain functioning). The aim of this study is to explore the brain activity of schizophrenia patients during different inhibitory tasks. We used functional magnetic resonance imaging to investigate to investigate the restraint and deletion aspects of inhibition in 19 patients with schizophrenia and 12 normal subjects during the performance of the Hayling and the N-back tasks.
