- Physical examination to screen for peripheral artery disease in a defined Primary Care population: A diagnostic accuracy study. [Journal Article]
- IJInt J Clin Pract 2018 Sep 17; :e13253
- CONCLUSIONS: In a mainly asymptomatic Primary Care population, pedal pulse palpation was by far the best diagnostic test, with good diagnostic accuracy and inter-rater agreement. In view of a high sensitivity and capacity to rule out the disease, pedal pulse palpation could be performed as a screening test for PAD and individuals at high cardiovascular risk.

We present the MIGA experiment, an underground long baseline atom interferometer to study gravity at large scale. The hybrid atom-laser antenna will use several atom interferometers simultaneously interrogated by the resonant mode of an optical cavity. The instrument will be a demonstrator for gravitational wave detection in a frequency band (100 mHz-1 Hz) not explored by classical ground and space-based observatories, and interesting for potential astrophysical sources. In the initial instrument configuration, standard atom interferometry techniques will be adopted, which will bring to a peak strain sensitivity of [Formula: see text] at 2 Hz. This demonstrator will enable to study the techniques to push further the sensitivity for the future development of gravitational wave detectors based on large scale atom interferometers. The experiment will be realized at the underground facility of the Laboratoire Souterrain à Bas Bruit (LSBB) in Rustrel-France, an exceptional site located away from major anthropogenic disturbances and showing very low background noise. In the following, we present the measurement principle of an in-cavity atom interferometer, derive the method for Gravitational Wave signal extraction from the antenna and determine the expected strain sensitivity. We then detail the functioning of the different systems of the antenna and describe the properties of the installation site.

Thyrotoxic periodic paralysis (TPP) is a rare and potentially lethal complication of hyperthyroidism. It is characterized by sudden onset paralysis associated with hypokalemia. Management includes prompt normalization of potassium, which results in resolution of the paralysis. Definitive treatment of hyperthyroidism resolves TPP completely.
- Speech audiometry in noise: Development of the French-language VRB (vocale rapide dans le bruit) test. [Journal Article]
- EAEur Ann Otorhinolaryngol Head Neck Dis 2018 Jul 30
- CONCLUSIONS: The VRB (vocale rapide dans le bruit: rapid speech in noise) test is based on sentences from the MBAA corpus with background noise based on the OVG at different signal-to-noise ratios. The test is feasible and able to detect slight variations in speech-in-noise performance between subjects.

A carotid cavernous fistula is a rare type of arteriovenous (AV) fistula due to an abnormal communication between the cavernous sinus and the carotid arterial system. Normal venous return to the cavernous sinus is impeded as high-pressure arterial blood enters the cavernous sinus. The classical triad of symptoms is characterized by pulsating exophthalmos, ocular bruit, and conjunctival chemosis. However, it is important to note that some patients do not exhibit this triad of symptoms.

Resistant hypertension is defined by the inability to maintain within normal limits the blood pressure values of an individual, while he is under treatment with maximal tolerated doses of three antihypertensive agents. One of the most common types of resistant hypertension is renovascular hypertension (RVH), which is caused by the narrowing of the renal arteries, in the context of existing atherosclerotic plaques at that level. We are presenting the case of a hypertensive 56-year-old man admitted in the Clinic of Cardiology for a sudden rise of his blood pressure values, despite undergoing the scheduled treatment. The abdominal bruit discovered at the clinical examination and the hypokalemia, together with the mild impairment of the renal function raised the suspicion of an existing stenosis of the main renal blood vessels. Simple grey scale kidney ultrasound, Doppler ultrasound of the renal arteries, abdominal computed tomography and magnetic resonance angiography of the renal arteries, along with invasive renal angiography demonstrated a smaller right kidney, adrenal incidentalomas, reduced vascular diameter of renal arteries due to atheromatous lesions, thrombosis of the infrarenal segment of the abdominal aorta, and reduced vascular hemodynamics in the same territories. After the renal arteries revascularization and with minimal antihypertensive treatment, the patient had a favorable outcome, with normalization of blood pressure and renal function. Atherosclerotic disease causing renal artery stenosis is essential to be taken into consideration in the etiopathogenesis of resistant hypertension especially because RVH is a potentially curable disease.

Advances in endovascular embolization have improved morbidity and mortality among patients with vein of Galen malformations (VoGMs). The patient presented at 3 months of age with increased head circumference and a bruit over his anterior fontanelle. Diagnostic cerebral angiography confirmed the presence of a large mural-type VoGM. The decision was made to undergo a staged arterial embolization at 4 years of age after developing worsening right-sided hemiparesis. An attempt was made to occlude the posterior choroidal feeding vessel with a large 25 mm × 50 cm coil, followed by a 6 mm × 20 cm coil; however, the high flow of the lesion displaced both coils into the wall of the aneurysmal venous sac. Interval magnetic resonance imaging and angiography revealed partial occlusion of the VoGM at 7 months and complete thrombosis at 24 months post procedure, precluding a need for additional coiling. This case illustrates that a minimal change in intramural flow dynamics of VoGMs could lead to progressive thrombosis.

We describe a patient with traumatic carotid-cavernous fistula (CCF), subsequently developing contralateral extensive hemorrhagic venous infarction from retrograde venous reflux into the opposite basal vein of Rosenthal. A 54-year-old woman was involved in a motor vehicle accident and sustained severe traumatic brain injury. Two months later, she developed bilateral proptosis and audible bruit. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brain demonstrated the right direct CCF. Fluid-attenuated inversion recovery (FLAIR) images showed a small hyperintense area at the left basal ganglia. Ten days later, she developed right-sided grade 2/5 hemiparesis, facial upper motor neuron weakness, and cognitive impairment. Follow-up MRI showed significant progression of hyperintensities involving the left-sided centrum semiovale, basal ganglia, thalamus, midbrain, pons, cerebellum, basal frontal, temporal lobes, especially subcortical white matter on FLAIR images, and multiple hypointense foci of hemorrhagic component on T2*-weighted gradient-echo images, representing hemorrhagic venous infarction. While waiting for embolization, she rapidly developed right hemiplegia and aphasia, and became somnolent. Under general anesthesia, emergency endovascular treatment was performed successfully to obliterate the fistula without surgical intervention. Five months after endovascular treatment, MRI and MRA confirmed no residual fistula and revealed nearly complete resolution of abnormal increased signal intensity. In the present case, the factors related to the presence of this rare condition were absence of the ipsilateral basal vein of Rosenthal (BVR), occlusion of posterior segment of the contralateral superior petrosal sinus, and a developed uncal vein with hypoplastic second and third segments of the contralateral BVR.
