Initial experience, feasibility, and technical development with an electromagnetic navigation assistance in percutaneous pelvic bone cementoplasty: retrospective analysis.

Objectives: To assess the feasibility and technical outcomes of pelvic bone cementoplasty using an electromagnetic navigation system (EMNS) in standard practice.

Materials And Methods: Monocentric retrospective study of all consecutive patients treated with cementoplasty or reinforced cementoplasty of the pelvic bone with EMNS-assisted procedures. The endpoints were periprocedural adverse events, needle repositioning rates, procedure duration, and radiation exposure.

Arterial Spin-Labeling Perfusion Imaging in the Early Stage of Sturge-Weber Syndrome.

Background And Purpose: Sturge-Weber syndrome is a rare congenital neuro-oculo-cutaneous disorder. Although the principal mechanism of Sturge-Weber syndrome is characterized by a leptomeningeal vascular malformation, few data regarding perfusion abnormalities of the brain parenchyma are available. Therefore, the aim of this study was to assess the diagnostic performance of arterial spin-labeling perfusion imaging in the early stage of Sturge-Weber syndrome before 1 year of age until 3.

Angiographic Anatomy of the Middle Meningeal Artery in Relation to Chronic Subdural Hematoma Embolization.

Purpose: Middle meningeal artery (MMA) embolization is emerging as a potential treatment of chronic subdural hematomas (CSDHs). The purpose of this study is to describe MMA angiographic anatomy in relation to CSDH embolization.

Methods: This retrospective monocentric study was performed on imaging data of MMA embolization procedures for CSDH treatment performed between March 15, 2018 and April 30, 2020.

CTA-Based Patient-Tailored Femoral or Radial Frontline Access Reduces the Rate of Catheterization Failure in Chronic Subdural Hematoma Embolization.

Background And Purpose: Chronic subdural hematoma embolization, an apparently simple procedure, can prove to be challenging because of the advanced age of the target population. The aim of this study was to compare 2 arterial-access strategies, femoral versus patient-tailored CTA-based frontline access selection, in chronic subdural hematoma embolization procedures.

Materials And Methods: This was a monocentric retrospective study.

Larger Middle Meningeal Arteries on Computed Tomography Angiography in Patients with Chronic Subdural Hematomas as Compared with Matched Controls.

Chronic subdural hematomas (CSDHs) are one of the most prevalent head-trauma-related conditions. The middle meningeal artery (MMA) may participate in the pathophysiology of CSDHs. The aim of this study was to determine whether CSDHs are associated with large MMAs.

Middle meningeal artery embolization reduces the post-operative recurrence rate of at-risk chronic subdural hematoma.

Background: Embolization of the middle meningeal artery (MMA) has emerged as a potential treatment of chronic subdural hematomas (CSDHs).

Objective: To evaluate the impact on recurrence rate of postsurgical embolization of CSDH in patients with a higher than average risk of recurrence.

Methods: A monocentric retrospective study was performed on retrospectively collected data.

[French program of breast cancer screening: Radiologist viewpoint].

French program of breast cancer screening is implemented since15 years and results are in adequation with international guidelines except for participation. To answer to recurrent controversies about breast cancer screening, publications from National Institute of French cancer registry confirm the positive impact of screening on decreasing mortality for participating women. The harms of mammography (and not from screening) need to be communicated to the invited women to help them to make decision about participation but also the risk of worse prognosis in case of symptomatic cancer.

Size and charge characterization of polymeric drug delivery systems by Taylor dispersion analysis and capillary electrophoresis.

In this work, Taylor dispersion analysis and capillary electrophoresis were used to characterize the size and charge of polymeric drug delivery nanogels based on polyglutamate chains grafted with hydrophobic groups of vitamin E. The hydrophobic vitamin E groups self-associate in water to form small hydrophobic nanodomains that can incorporate small drugs or therapeutic proteins. Taylor dispersion analysis is well suited to determine the weight average hydrodynamic radius of nanomaterials and to get information on the size polydispersity of polymeric samples.

Pure flat epithelial atypia: is there a place for routine surgery?

Purpose: To determine whether it is appropriate to routinely undertake surgery if flat epithelial atypia (FEA) or pure flat epithelial atypia (pFEA) is found on large-core biopsy.

Patients And Methods: Between 2005 and 2010, 1678 large-core biopsy procedures were carried out, which led to 136 FEA sites being identified, 63 of which across 59 patients were pFEA (four patients had two sites of pFEA each). Forty-eight patients underwent further surgical excision, equating to 52 excised sites of pFEA.

Clinical utility and economic viability of a 3T MRI in an anti-cancer centre: The experience of the centre Oscar Lambret.

This paper will try and describe the installation of a 3T MRI in an anti-cancer centre. Functional sequences become indispensable in the assessment of targeted treatments. It is only possible to carry out these treatments on a routine basis in acceptable examination times with 3T.

[Diagnosis of a calcified intramural mass next to the posterior mitral valve: review of 4 cases].

Purpose: Calcified intramural tumors next to the posterior mitral valve leaflet are rare. The purpose of this paper is to review the differential diagnosis of such lesions.

Patients And Methods: The CT and MR imaging features of 4 patients (2 males, 2 females) aged between 67 and 76 years with calcified mass at the base of the mitral valve annulus on echocardiogram are reviewed.

Photoresponsive viscosity and host-guest association in aqueous mixtures of poly-cyclodextrin with azobenzene-modified poly(acrylic)acid.

In aqueous solutions, beta-cyclodextrin (CD) and cyclodextrin-containing polymers (PolCD) associate with azobenzene-modified polyacrylate (AMP). Inclusion complexes in solution of CD (or PolCD) and AMP, and the viscosity of these mixtures, have been studied as a function of the composition of AMP and concentrations of samples. AMPs are random copolymers containing a low fraction of a light-responsive hydrophobic moieties (<10 mol % of 6-[4-alkylamido]phenylazobenzene acrylamide), and a charged hydrophilic unit, sodium acrylate.

Maximal exercise and muscle energy metabolism after recovery from exercise hyperthermia syndrome.

Muscle energy metabolism was studied in 30 subjects after recovery from exercise hyperthermia syndrome (EHTS subjects) and 15 healthy men with identical physical activities. Blood lactate, free fatty acid (FFA), serum creatine kinase activity (CK), and glycerol and the temperature in the auditory duct (T(c)) and on the thumb pad (T(sk)) were measured at rest and during and after maximal exercise on a cycloergometer. The EHTS subjects had a limitation of physical performance, with lowered values for maximal oxygen uptake (VO(2max), P < 0.

Swan-Ganz catheter-related pulmonary valve infective endocarditis: a case report.

We report the case of a 29-year-old man with decompensated alcoholic cardiomyopathy who developed a Staphylococcal pulmonic valve infective endocarditis during hemodynamic monitoring, as a consequence of catheter-related bacteremia. As experimentally demonstrated, the damaging role of the pulmonary artery catheter on the endocardial surface plays a major role in the pathogenesis of related right-sided infective endocarditis. Occurrence of bacteremia in a catheterized patient should be considered as a high risk situation, and righ-heart infective endocarditis must be suspected whenever patient presents fever or bacteremia without obvious site of infection.

[Results of the use of a monoblock pin-plate in trochanteric fracture in elderly patients. Apropos of 100 cases].

The authors report their experience of the systematic use of a monobloc pin-plate in fractures of the trochanteric region in the elderly. The review of a series of 100 cases with a mortality of 16% demonstrates that this technique ensures excellent results compared with other published series. The biomechanical reliability of the monobloc pin-plate allows immediate weight-bearing in all patients.
