Patients with chronic obstructive pulmonary disease (COPD) face an increased respiratory load and in consequence have an elevated respiratory drive. We used transcranial magnetic stimulation (TMS) to investigate associated changes in corticospinal excitability both at rest and during voluntary facilitation at different levels of inspiratory effort.(More)
We studied 263 cases of Guillain-Barré syndrome from 1996 to 2001, 40% of which were associated with a known causative agent, mainly Campylobacter jejuni (22%) or cytomegalovirus (15%). The cases with no known agent (60%) peaked in winter, and half were preceded by respiratory infection, influenza-like syndrome, or gastrointestinal illness.
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by the association of severe headaches with or without additional neurological symptoms and a 'string and beads' appearance on cerebral arteries, which resolves spontaneously in 1-3 months. We present the clinical, neuroimaging and outcome data of 67 consecutive patients prospectively(More)
Diffusion tensor imaging can be used in vivo to assess the longitudinal and regional microstructural changes occurring after middle cerebral artery (MCA) infarcts in humans. Nine patients were investigated 1 week (D7), 1 (M1), 3 (M3), and 6 months (M6) after the occurrence of an isolated MCA infarction. First, an overall analysis was performed using(More)
BACKGROUND Cross-immunity between seasonal and pandemic A/H1N1 influenza viruses remains uncertain. In particular, the extent that previous infection or vaccination by seasonal A/H1N1 viruses can elicit protective immunity against pandemic A/H1N1 is unclear. METHODOLOGY/PRINCIPAL FINDINGS Neutralizing titers against seasonal A/H1N1 (A/Brisbane/59/2007)(More)
OBJECTIVES Illness is often associated with anxiety, but few data exist about the prognostic significance of this phenomenon. To address this issue, we assessed whether patient anxiety is associated with subsequent need for intubation in Guillain-Barré syndrome (GBS). DESIGN Incident case-cohort study. SETTING Acute secondary care in a teaching hospital(More)
BACKGROUND Hepatitis C virus (HCV) has been detected in sperm, but no data are available on follicular fluid (FF) collected on IVF procedures. The aim of this study was to: (i) search for HCV RNA in FF and in culture media at each step of IVF undergone by HCV(+) women; (ii) investigate the impact of blood contamination of FF induced by vascular injury(More)
Few studies focused on concomitant electromyographic recordings of pelvic floor muscles and muscles involved in cough initiation. The objective of this study was to investigate the temporal course of external anal sphincter activation during coughing. Informed consent was obtained from ten healthy volunteers and ten women presenting with stress urinary(More)
