OBJECTIVE We compared pregnancy outcomes among women with sickle cell disease with outcomes for African American women without the disease. STUDY DESIGN We selected 127 deliveries in women with sickle cell disease (hemoglobin SS or hemoglobin SC) that occurred between 1980 and 1999. A control group of 129 deliveries by African American women with normal(More)
Three cases of non-healing granuloma with neurological complications are described. One case suffered from Stewart's form of the disease and two from Wegener's variety. The literature is extensively reviewed and the incidence and manner of neurological involvement in 374 cases is discussed. We suggest a classification to indicate four forms of nervous(More)
Dabigatran is effective in decreasing the risk of ischaemic stroke in patients with atrial fibrillation. However, like all anticoagulants, it is associated with a risk of bleeding. In cases of trauma or emergency surgery, emergency reversal of dabigatran-induced anticoagulation may be required. A specific reversal agent for dabigatran, idarucizumab, has(More)
We trained unilingual adult Canadian francophone listeners to identify the English voiceless and voiced linguadental ("th") frictives, /theta/ and /delta/, using synthetic exemplars of each phoneme. Identification training with feedback improved listeners' abilities to identify both natural and synthetic tokens. These results show that training with(More)
Endplate acetylcholinesterase (AChE) consists of globular catalytic subunits attached to the basal lamina by a collagen-like tail. Different genes encode the catalytic subunit and the tail portion of the enzyme. Endplate AChE deficiency was reported previously in a single case (Engel et al., 1977, patient 1). We describe here our observations in four(More)
The introduction of the triptans (5-hydroxytryptophan [5-HT] (1B/1D) agonists) in the past decade has brought migraine-specific pain relief to those suffering from migraine. These drugs activate the serotonin receptors 5-HT(1B) and 5-HT(1D) on cerebral vessels. Concerns about their safety, particularly in patients with vascular risk factors, have been(More)
People who are unable to hear acoustic alarm signals because they have a complete or partial hearing loss must rely on visual or tactile signals to warn them in the event of an emergency. However, consumers report that personal smoke detector devices which provide a visual alarm do not wake people reliably. We examined the ability of visual alerting devices(More)
We studied the relation of serum glucose level measured in the first 12 hours of symptoms to the clinical findings, results of computed tomography (CT), and patterns of cerebral metabolism in 39 patients who had acute ischemic cerebral infarction. Structural damage was assessed by CT. Metabolic disruption was assessed using 18F-fluorodeoxyglucose and(More)
The authors examined eight patients with dementia of the Alzheimer's type (DAT), five with prominent visual symptoms early in the illness (VS) and three with no visual symptoms (NVS). Results of neuro-ophthalmologic examinations on VS patients showed relatively consistent abnormalities in figure copying, color vision tested by isochromatic plates, and(More)
