Kaliotoxin (KTX), a blocker of voltage-gated potassium channels (Kv), is highly selective for Kv1.1 and Kv1.3. First, Kv1.3 is expressed by T lymphocytes. Blockers of Kv1.3 inhibit T lymphocyte activation. Second, Kv1.1 is found in paranodal regions of axons in the central nervous system. Kv blockers improve the impaired neuronal conduction of demyelinated(More)
We evaluated the concordance between independent clinical, electrophysiological, and [(123)I]-FP-CIT SPECT scan explorations as a staged procedure for an accurate diagnosis in 9 patients referred with a diagnosis of suspected psychogenic parkinsonism. Three patients were reclassified as pure psychogenic parkinsonism (PP), 6 with a form of combined(More)
In vitro RBC production from stem cells could represent an alternative to classic transfusion products. Until now the clinical feasibility of this concept has not been demonstrated. We addressed the question of the capacity of cultured RBCs (cRBCs) to survive in humans. By using a culture protocol permitting erythroid differentiation from peripheral CD34(+)(More)
UNLABELLED Although 18F-FDG examinations are widely used, data are lacking on the dose to human embryo tissues in cases of exposure in early pregnancy. Although the photon component can easily be estimated from available data on the pharmacokinetics of 18F-FDG in female organs and from phantom measurements (considering the uterus as the target organ), the(More)
Bone is the second most frequent target of distant metastases in patients with differentiated thyroid cancer, and such forms carry a very poor prognosis. The impact of (131)I therapy in this setting is controversial. We describe the diagnostic circumstances and outcome of patients with bone metastases recently managed in two institutions. Among 921(More)
OBJECTIVES The aim of this research was to examine the effects of perindopril on cardiac function in patients with Duchenne muscular dystrophy (DMD). BACKGROUND Duchenne muscular dystrophy, an inherited X-linked disease, is characterized by progressive muscle weakness and myocardial involvement. METHODS In phase I, 57 children with DMD and a left(More)
UNLABELLED Rapid-onset dystonia-parkinsonism (RDP) is a rare, autosomal-dominantly inherited syndrome characterized by abrupt onset, over hours to days, of dystonic and parkinsonian symptoms. To date, RDP has been described in a small number of families, and in only four sporadic cases. METHODS We here report a new sporadic case of RDP who has a novel de(More)
Hybrid positron emission tomography/computed tomography (PET/CT) has now become available, as well as whole-body, low-dose multidetector row computed tomography (MDCT) or magnetic resonance imaging (MRI). The radioactive glucose analogue 18F-fluorodeoxyglucose (FDG) is the most widely used tracer but has a relatively low sensitivity in detecting multiple(More)
Méditerranean Periodic Disease is frequently encountered in non-aschenazic Jews and in Armenians. Aside from the classic triad of pseudo-palustral febrile crises, paroxysms of abdominal and articular pain, and a biological syndrome of inflammation; cutaneous manifestations were noted in 25 to 35% of the cases according to various authors. The most commonly(More)
