OBJECTIVE diffusion-weighted magnetic resonance imaging (DWI) is a sensitive diagnostic tool for detecting acute ischaemic lesions in patients with transient ischaemic attacks (TIAs). The additional predictive value of DWI lesion patterns is not well known. METHODS two hundred and fifty-four consecutive patients with TIA underwent DWI within 7 days of(More)
A family with adult spinal and bulbar muscular atrophy with X-linked recessive inheritance (Kennedy's disease) is described. Affected members presented at age 20 with muscle cramps followed insidiously by gynaecomastia, partial loss of secondary sexual traits, loss of libido and inability to maintain an erection. Three had also testicular atrophy and severe(More)
BACKGROUND AND PURPOSE High levels of glutamic acid decarboxylase (GAD)-ab were initially described in patients with stiff person syndrome, and have since also been observed in patients with other neurological diseases. Temporal lobe epilepsy (TLE) seems to be specially associated. Our purpose is to describe the prevalence of GAD-ab in patients with TLE,(More)
Complex motor behaviors differing from typical automatisms were found in 12 of 502 patients with temporal lobe epilepsy. Movements involved proximal limb segments (6) or body axis (6) and were often preceded by auras and followed by automatisms. Seven of 12 patients are seizure free after surgery. The other 5 patients declined surgery.
The bark of Rhizophora mangle, the red mangrove, has been used traditionally in folk medicine of Caribbean countries due to its antiseptic, astringent, haemostatic and antifungal properties. Aqueous extracts are rich in tannins and have been proven experimentally to possess antibacterial, wound healing and antiulcerogenic effects. This work was designed to(More)
OBJECTIVE To discover, by using metabolomics, novel candidate biomarkers for stroke recurrence (SR) with a higher prediction power than present ones. METHODS Metabolomic analysis was performed by liquid chromatography coupled to mass spectrometry in plasma samples from an initial cohort of 131 TIA patients recruited <24 hours after the onset of symptoms.(More)
BACKGROUND The ankle brachial index (ABI) is a known measure of lower-limb peripheral artery disease (PAD), as well as a marker for other cardiovascular disease events. OBJECTIVE Our goal was to compare the prevalence of abnormal ABI scores (ABI <or= 0.9) between: consecutive patients with acute ischaemic stroke (IS), primary care patients with refractory(More)
BACKGROUND AND PURPOSE The etiological classification of patients with transient ischaemic attack (TIA) is a difficult endeavor and the use of serum biomarkers could improve the diagnostic accuracy. The aim of this study was to correlate atrial fibrillation, the main cardioembolic etiology (CE), with different serum biomarkers measured in consecutive TIA(More)
BACKGROUND AND PURPOSE High-b-value diffusion-weighted imaging (DWI) (b = 2,000 and b = 3,000 second/mm(2)) offers theoretical advantages over DWI examinations at b = 1,000 second/mm(2) for detection of acute ischemic stroke. The purpose of this study was to determine whether high-b-value DWI are better than b = 1,000 images in TIA patients. METHODS We(More)
BACKGROUND Most approaches to transient ischaemic attack (TIA) triage use clinical scores and vascular imaging; however, some biomarkers have been suggested to improve the prognosis of TIA patients. METHODS Serum levels of copeptin, adiponectin, neopterin, neuron-specific enolase, high-sensitivity C-reactive protein, IL-6, N-terminal pro-B-type(More)
