Dissociable Effects of Reward on P300 and EEG Spectra Under Conditions of High vs. Low Vigilance During a Selective Visual Attention Task
2020
The influence of motivation on selective visual attention in states of high vs. low vigilance is poorly understood. To explore the possible differences in the influence of motivation on behavioral performance and neural activity in high and low vigilance levels, we conducted a prolonged 2 h 20 min flanker task and provided monetary rewards during the 20- to 40- and 100- to 120-min intervals of task performance. Both the behavioral and electrophysiological measures were modulated by prolonged task engagement. Moreover, the effect of reward was different in high vs. low vigilance states. The monetary reward increased accuracy and decreased the reaction time (RT) and number of omitted response…
Use of neural networks for dosage individualisation of erythropoietin in patients with secondary anemia to chronic renal failure.
2003
The external administration of recombinant human erythropoietin is the chosen treatment for those patients with secondary anemia due to chronic renal failure undergoing periodic hemodialysis. The goal is to carry out an individualised prediction of the erythropoietin dosage to be administered. It is justified because of the high cost of this medication, its secondary effects and the phenomenon of potential resistance which some individuals suffer. One hundred and ten patients were included in this study and several factors were collected in order to develop the neural models. Since the results obtained were excellent, an easy-to-use decision-aid computer application was implemented.
PULMONARY AND CARDIAC COMPLICATIONS OF STAPHYLOCOCCAL OSTEOMYELITIS
1985
Pulmonary complications of staph.osteomyelitis seem to be infrequent and are seldom related in wide reviews of this entity and in texts of infectious diseases.Cardiac complications are still more infrequently found.However our experience is far from this observation. We have found pneumonic interstitial infiltrates and/or asymptomatic pneumatoceles in about two thirds of children suffering from staph. osteomyelitis to whom we have taken a weekly chest radiograph while they were feverish.Severe forms are rare.Lately,however,we have treated 5 children with acute staph.osteomyelitis,aged 6 to 13,and whith severe pulmonary and cardiac complications.They had broad bone lesions which affected (1)…
Dolichoectasia of the vertebrobasilar complex causing neural compression
2014
Dear Editor, We have read with great interest the paper of Yuh et al.[4] reporting a case of symptomatic hydrocephalus due to vertebrobasilar dolichoectasia (VBD) compressing the brainstem. Ectatic or pathologically enlarged vertebrobasilar arteries have been reported with increasing frequency and associated with several clinical syndromes. These include an assortment of cranial nerve syndromes, transient or permanent motor deficit, cerebellar dysfunction, central sleep apnea, ischemic stroke, hypertension, and hydrocephalus as reported in the paper by Yuh et al.[4] Others and we have also described pyramidal tract signs and cranial nerve nucleus dysfunction caused by vascular compression o…
Zonal Segmentation of Prostate T2W-MRI using Atrous Convolutional Neural Network
2019
The number of prostate cancer cases is steadily increasing especially with rising number of ageing population. It is reported that 5-year relative survival rate for man with stage 1 prostate cancer is almost 99% hence, early detection will significantly improve treatment planning and increase survival rate. Magnetic resonance imaging (MRI) technique is a common imaging modality for diagnosis of prostate cancer. MRI provide good visualization of soft tissue and enable better lesion detection and staging of prostate cancer. The main challenge of prostate whole gland segmentation is due to blurry boundary of central gland (CG) and peripheral zone (PZ) which lead to differential diagnosis. Sinc…
Early developmental alterations of low-Mg2+ -induced epileptiform activity in the intact corticohippocampal formation of the newborn mouse in vitro.
2005
Abstract The generation, propagation and pharmacological properties of low-Mg 2+ -induced epileptiform activity were examined in the intact corticohippocampal formation (CHF) of the newborn (P0–4) mouse in vitro. Multi-site field potential recordings in dentate gyrus (DG), CA3, CA1, entorhinal cortex (EC) and temporal cortex (TC) revealed in 0.2 mM Mg 2+ -containing ACSF a stable pattern of spontaneous epileptiform activity consisting of recurrent ictal-like events (ILEs) and interictal events (IEs). Although this activity could be consistently observed as early as P0, ILEs were smaller in amplitude, less frequent and showed a slower onset in P0–2 as compared to P3–4 animals. In all age gro…
Newborn hearing-screening project using transient evoked otoacoustic emissions: western sicily experience
2006
Summary Objective To study the incidence of congenital sensorineural hearing loss in all newborns introducing a screen test with a protocol no expensive, with a good “screen sensitivity” that could let an earlier identification of hearing impairment beginning early intervention by 2 months of age and increasing the probability of having language development within the normal range of development. Methods The study was conducted in Sciacca hospital from the beginning of 2003 to our days and was carried out with transient evoked otoacoustic emission using the criteria for PASS or RETEST and considering eventual prenatal and perinatal risk factors. All the newborns were divided into four group…
Clozapine-related drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome: a systematic review.
2020
The Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a severe, multiorganic, and potentially life-threatening drug-induced hypersensitivity reaction, linked to several common drugs, including antiepileptics, antibiotics, and several psychotropic drugs, including clozapine. Due to the importance of clozapine in the management of treatment-resistant schizophrenia, a systematic review and characterization of clozapine-related DRESS syndrome is long overdue.This systematic review was conducted following PRISMA guidelines. PubMed, Embase, PsychINFO, and the Cochrane Library databases were independently reviewed up to 1 November 2019 for articles reporting clozapine-relat…
Unusual recurrence of trigeminal neuralgia after microvascular decompression by muscle interposal.
2011
Summary Background Patients with trigeminal neuralgia (TN) and persistent or recurrent facial pain after microvascular decompression (MVD) typically undergo less invasive procedures in the hope of providing pain relief. However, re-operation should be considered in selected patients. Case Report A 48-year-old woman presented with recurrent trigeminal neuralgia (TN) 3 years following microvascular decompression (MVD). The patient underwent brain magnetic resonance angiography (MRA), which did not reveal neurovascular compression; therefore surgical re-exploration was carried out. During the operation, the fifth cranial nerve was seen without impingement from any blood vessels; however, a ver…
The sleep EEG's microstructure in depression: alterations of the phase relations between EEG rhythms during REM and NREM sleep
2002
Abstract Objective : We investigated the microstructure of sleep electroencephalograms (EEGs) of 13 unmedicated depressive inpatients and 13 healthy controls matched in sex and age, hypothesizing that depressives depict an alteration of certain EEG oscillations across the night. Methods : We digitized the sleep EEGs with a sampling rate of 100Hz (bipolar derivation C z –P z , 1440 single sweeps; 2048 data points each), calculated the time course of delta (1–3.5Hz), theta (3.5–7.5Hz), alpha (7.5–15Hz), and beta (15–35Hz) activity over the night, and determined the correlation coefficients of these different EEG rhythms separately for rapid eye movement (REM) and non-rapid eye movement (NREM)…
