Blood levels of homocysteine, cysteine, glutathione, folic acid, and vitamin B12 in the acute phase of atherothrombotic stroke.

2009

Blood levels of total homocysteine (tHcy), cysteine (Cys), total and reduced glutathione (tGSH and rGSH), folic acid (FA), and vitamin B(12) (B(12) change during ischemic stroke as accompaniment of the tissue damage. The relationship between these changes remains scantly investigated. We evaluated the variation of these molecules in the 48 h after acute large artery atherothrombotic stroke (LAAS) and searched for the presence of matched variation of them. The study involved 50 subjects affected by acute LAAS and 49 healthy controls. Plasma levels of tHcy and Cys were significantly higher and serum levels of FA and B(12) and plasma levels of rGSH were significantly lower in the patients than…

Peripheral Neuropathy in the Hypereosinophilic Syndrome: A Case Report

1989

We observed a patient with the hypereosinophilic syndrome that showed as a prominent clinical feature peripheral nerve dysfunction. The neuropathy evolved over 4 months and affected sensory and motor functions. Nerve conduction studies and EMG were compatible with axonal neuropathy. Nerve and muscle biopsies revealed severe axonal degeneration with neurogenic atrophy of muscle. Morphometry of peroneal nerve showed marked axonal loss, more prominent in large myelinated fibers. There was no evidence of vasculitis process. Neuropathy is produced by eosinophil-released substances exerting a neurotoxic effect through direct altered vascular endothelial permeability and local mast cell histamine …

Pancreatic encephalopathy: a 7-year follow-up case report and review of the literature

2003

Pancreatic encephalopathy is a rare complication of acute pancreatitis. Clinical features include focal neurological signs and acute onset of dementia. This picture can fluctuate over time: cyclic progression with remission and relapses has been described. We present the case of a 43-year-old man who, after an acute episode of pancreatitis, experienced five relapses, with alternating focal signs. The patient has improved, but cognitive impairment persists after a 7-year follow-up.

Ocular pseudomyasthenia: report of a case with a pineal region tumor.

1991

A case presenting with clinical features of ocular myasthenia and a false-positive edrophonium test is reported. Brain CT and MRI scan revealed a pineal region tumor histologically verified as germinoma. We recommend evaluating patients with clinical features of myasthenia gravis (MG) confined to the ocular muscles for intracranial mass lesions.

Accuracy of death certificates for motor neuron disease and multiple sclerosis in the province of Palermo in southern Italy

2002

Mortality studies based on death certificates (DCs) are relatively inexpensive and easy to conduct. Therefore, they are frequently used to evaluate variations of geographical and temporal patterns, particularly in uncommon diseases. Recent surveys of motor neuron disease (MND) and multiple sclerosis (MS) based on official mortality statistics in Italy showed a decreasing trend of mortality from northern to southern Italy. To evaluate if DCs are homogeneously recorded in Italy and whether or not they can be considered a good instrument for mortality studies, we assessed the accuracy of DCs for MND and MS in the province of Palermo, Italy, and compared our results with those reported in other…

Hypo-excitability of cortical areas in patients affected by Friedreich ataxia: A TMS study

2005

The aim of the study was to explore excitability of a motor and a non-motor (visual) area in patients affected by Friedreich ataxia and to correlate neurophysiological data with clinical parameters. Seven patients (3M/4F) and ten healthy controls (5M/5F) participated in the study. The hot-spot for activation of right abductor pollicis brevis was checked by means of a figure-of-eight coil and the motor threshold (MT) on this point was recorded. The phosphene threshold (PT) was measured by means of a focal coil over the occipital cortex as the lower intensity of magnetic stimulation able to induce the perception of phosphenes. The patients showed a significantly higher mean PT (p<.03) and MT …

Motor intracortical inhibition in PD: L-DOPA modulation of high-frequency rTMS effects

2007

Dopaminergic drugs and deep brain stimulation restore cortical inhibition in Parkinson disease (PD) patients. High-frequency rTMS was also found to increase cortical inhibition in PD but its therapeutic effect is still controversial. Here we hypothesize that, if dopaminergic drugs reverse to normal cortical excitability in M1, the effect of high-frequency (hf)-rTMS in PD patients could depend on whether they are in a medicated or unmedicated state. The present study aims to explore the lasting effects of sub-threshold hf rTMS trains over M1 on cortical inhibition in patients with "on" and without "off" L-DOPA treatment. Fourteen PD patients were examined twice while "on" and "off" medicatio…

Headache in cerebrospinal fluid volume depletion syndrome: A case report

2006

Cerebrospinal fluid (CSF) volume depletion syndrome is due to leakage of cerebrospinal fluid through lesions of the dural sac at the level of the cranial base or of the spine. When past medical history is negative for recent trauma or surgery, the term spontaneous intracranial hypotension (SIH) is used. SIH is characterized clinically by orthostatic headache, neck pain, nausea, emesis, horizontal diplopia, tinnitus, plugged ear, hearing difficulties, blurring of vision, facial numbness, and upper limb radicular symptoms. In SIH, brain and cervical MR scans show a diffuse pachymeningeal gadolinium enhancement that ends at the site of CSF leakage. The application of epidural blood patches has…

Frequency and determinants for hemorrhagic transformation of cerebral infarction.

2009

&lt;i&gt;Background:&lt;/i&gt; Frequency and associated risk factors for hemorrhagic transformation (HT), a worrying complication of ischemic stroke (IS), are not clearly defined. Our aim was to estimate the overall frequency and risk factors for HT in a hospital-based population. &lt;i&gt;Methods:&lt;/i&gt; A retrospective review of medical records of patients discharged from our department during the period 2004–2006 with a diagnosis of anterior IS. Demographic, clinical and hematological information was collected. Uni- and multivariate logistic regression analyses were used to estimate risk for spontaneous HT. &lt;i&gt;Results:&lt;/i&gt; We included 240 patients (125 males, 52%), mean ag…

A novel mutation of the extracellular matrix protein 1 gene (ECM1) in a patient with lipoid proteinosis (Urbach-Wiethe disease) from Sicily

2005

Summary Background  Lipoid proteinosis (LP), also known as Urbach–Wiethe disease, is a rare autosomal recessive disorder characterized by a hoarse voice, warty skin infiltration and scarring. Mutations within the extracellular matrix protein 1 (ECM1) gene cause LP. Objectives  We report the molecular analysis of the ECM1 gene in a Sicilian patient with LP in order to extend the mutation spectrum of this genodermatosis. Methods  We studied a 32-year-old female born from consanguineous parents who was diagnosed at the age of 11 years as having LP. She has a clinical phenotype corresponding to Urbach–Wiethe disease characterized by papules/nodules, indurated plaques and sometimes ulcerated les…

The relapse rate of multiple sclerosis changes during pregnancy: a cohort study

2004

Objective – To evaluate the influence of pregnancy and puerperium on the relapse rate of multiple sclerosis (MS). Methods – We determined retrospectively the yearly mean relapse rate (MRR) during pregnancies occurring in the course of relapsing–remitting MS. We compared the MRR of pregnancy-time with that of non-pregnancy time by paired t-test. Relative risk (RR) of relapses during the pregnancy-time was also compared with that of non-pregnancy time by χ2 analysis and 95% confidence intervals. Results – From a population of 351 women affected by clinically definite MS, only 70 reported pregnancies during their relapsing–remitting phase of MS for a total of 98 pregnancies. Both MRR (P = 0.00…

Myasthenia gravis associated with Charcot-Marie-Tooth neuropathy: report of a case

1992

We report the case of a 24 year old woman who developed myasthenia gravis in the course of a mild form of Charcot-Marie-Tooth neuropathy. We describe the clinical manifestations together with the neurophysiological, pathological, serological findings and response to therapy and discuss the unusual association in the light of the relevant literature. © 1992 Masson Italia Periodici S.r.l.
