Psychogenic pseudosyncope (PPS) is a common cause of apparent transient loss of consciousness (TLOC) with a dramatic impact on the quality of life. This review aims to give an overview of the definition, incidence, etiology, diagnosis, treatment, and prognosis of PPS based on a combination of literature data and personal experience. The limited literature on the subject suggests that PPS is rel...

OBJECTIVE To evaluate foot and ankle function in a series of patients undergoing fibula microvascular free tissue transfer. STUDY DESIGN A nonrandomized, nonblinded analysis was performed using the ankle-hindfoot scale as well as radiographic analysis to determine donor site morbidity. RESULTS Overall, foot ankle function was deemed to be good in this series of patients. Average ankle-hindf...

Life table methods were applied to analyses of longitudinal data on the use of medical care during the first 5 years of life among all 1701 children born in a Swedish semirural municipality. Cumulative proportions of the children who had used particular types of medical care or prescription drugs at least once by certain ages were estimated. By the fifth birthday, 98% had made at least one visi...

The tilt aftereffect (TAE) is a visual illusion in which prolonged adaptation to an oriented stimulus causes shifts in subsequent perceived orientations. Historically, neural models of the TAE have explained it as the outcome of response suppression of neurons tuned to the adapting orientation. Recent physiological studies of neurons in primary visual cortex (V1) have confirmed that such respon...

Forty patients with recurrent syncopal episodes of uncertain etiology were evaluated with a 60-degree head-up tilt table test for 60 minutes. There were 21 men and 19 women, with a mean age of 36 +/- 19 years, a mean of 7.6 syncopal episodes per patient, and a mean duration of symptoms of 4.2 +/- 6 years. Twelve patients had evidence of organic heart disease. Ten control subjects with no histor...

Head-up tilt-table test is valuable in diagnosing type of syncope. Sensitivity varies in reports and is mostly poor. Isoproterenol or nitroglycerin is regularly used to increase head-up tilt-table test sensitivity. The aim of this study was to assess the value of sublingual isosorbide dinitrate administration before isoproterenol tilt test as a simple, practical test for diagnosis of neurally m...

We comment on recently proposed algorithms for determining the number of zeros of a complex polynomial in a half-plane, such as Agashe's method (1985) and Benidir and Picinbono's ERT (1991). Following an exposition of Talbot (1960) we construct an easier device, which we call "Talbot's Table" (TT), to replace the old Routh's Table (RT). Moreover, it is shown that the old RT is capable of answer...

Previous studies have commented upon the similar phenomenology of simultaneous and successive interactions in the perception of orientation. These similarities have been taken as evidence of common mechanisms underlying the simultaneous tilt illusion (TI) and the successive tilt aftereffect (TAE). We measured the TI and TAE for four subjects for combinations of test and inducing stimuli modulat...

BACKGROUND The pathogenesis of chronic fatigue syndrome (CFS) is unknown. Neurally mediated hypotension (NMH) has been suggested as a common comorbid condition or a potential underlying cause. METHODS We conducted a cotwin control study of 21 monozygotic twins who were discordant for CFS. One twin met the 1994 Centers for Disease Control and Prevention criteria for CFS, and the other twin was...

This B.Sc. thesis report documents an implementation of the Pastry Distributed Hash Table (DHT) for the Network Simulator 3 (NS-3) simulation environment. To our knowledge, this thesis constitutes the first and only effort to cover the lack of any Pastry implementation for the NS-3 discrete event simulator. Given that NS-3 comes as an open source distribution, it is expected to meet the high de...
