Twenty-eight patients with sensory complaints of unknown etiology had repeated skin biopsies. Patients with large nerve fiber swellings on initial biopsy showed a decline in epidermal nerve fiber density on repeated biopsies (p < 0.05 within group; p < 0.05 vs those without swellings). Patients without nerve fiber swellings did not have changes in nerve(More)
Small-fiber neuropathy manifests in a variety of different diseases and often results in symptoms of burning pain, shooting pain, allodynia, and hyperesthesia. Diagnosis of small-fiber neuropathy is determined primarily by the history and physical exam, but functional neurophysiologic testing and skin biopsy evaluation of intraepidermal nerve-fiber density(More)
We present preliminary experiments of a binary-switch, static-grid typing interface making use of varying language model contributions. Our motivation is to quantify the degree to which language models can make the simplest scanning interfaces – such as showing one symbol at a time rather than a scanning a grid – competitive in terms of typing speed. We(More)
BACKGROUND Spontaneous osteonecrosis of the knee (SONK) is a distinct clinical condition occurring in patients without any associated risk factors. There is controversy as to the best method of treatment, and the available literature would suggest that patients with SONK have a worse outcome than those with primary osteoarthrosis when arthroplasty is(More)
PURPOSE Anterior cruciate ligament deficiency (ACLD) has been considered a contraindication for Oxford unicompartmental knee arthroplasty (UKA) because of the reported higher incidence of failure when implanted in ACLD knees. However, given the potential advantages of UKA over total knee arthroplasty (TKA), we have performed UKA in a limited number of(More)
Syncope is a common presenting complaint in both the inpatient and outpatient settings. The main goals in the clinical evaluation of syncope are to identify an underlying etiology, to stratify risk and to guide plans for therapeutic intervention. Testing begins with an initial electrocardiogram to screen for any cardiac rhythm abnormalities. Heart rate(More)
OBJECTIVE To investigate the relation between orthostatic hypotension (OH) and posture-mediated cognitive impairment in Parkinson disease (PD) using a cross-sectional and within-group design. METHODS Individuals without dementia with idiopathic PD included 18 with OH (PDOH) and 19 without OH; 18 control participants were also included. Neuropsychological(More)
OBJECTIVE To investigate the prevalence, symptoms, and neurophysiologic features of delayed orthostatic hypotension (OH). METHODS Blood pressures (BP) were measured at 1-minute intervals on 230 patients during 60 degrees head-up tilt for 45 minutes and standing for 5 minutes. OH was defined as a sustained fall in BP (>or=20 mm Hg systolic or >or=10 mm Hg(More)
Anabolic-androgenic steroid (AAS) effects on brain reward were investigated in male rats with electrodes implanted in the lateral hypothalamus using the rate-frequency curve shift paradigm of brain stimulation reward. In the first experiment, treatment for 2 weeks with the AAS methandrostenolone had no effect on either the reward or performance components(More)
