Abstract
Erythrocyte deformability is lower than normal in uncontrolled insulin-dependent diabetics and returns towards normal after 24 h treatment with a feedback-controlled insulin infusion. Deformability of normal erythrocytes is reduced by incubation in plasma from uncontrolled insulin-dependent diabetics but is normal in plasma from insulin-dependent diabetics controlled by 24 h insulin infusion, or in plasma from uncontrolled insulin-dependent diabetics with insulin added in vitro. Therefore, insulin has a direct action on erythrocyte deformability. Platelet aggregation measured in whole blood is raised in uncontrolled insulin-dependent diabetics and returns to normal after 24 h treatment with a feedback-controlled insulin infusion. Aggregation of normal platelets rises in the presence of erythrocytes from uncontrolled insulin-dependent diabetics, but not erythrocytes from the same patients after 24 h treatment with insulin. The effect of insulin on platelet aggregation therefore seems to be at least partly mediated by erythrocytes. The enhanced platelet aggregation seen in uncontrolled insulin-dependent diabetics can be explained either by a direct effect of erythrocyte rigidity or by an increased release of nucleotides (ADP) by the erythrocytes.

Abstract
OBJECTIVE To cross-sectionally compare the regional white matter fractional anisotropy (FA) of cognitively normal (CN) older individuals and patients with mild cognitive impairment (MCI) and Alzheimer disease (AD), separately focusing on the normal-appearing white matter (NAWM) and white matter hyperintensities (WMH), and to test the independent effects of presumed degenerative and vascular process on FA differences. METHODS Forty-seven patients with AD, 73 patients with MCI, and 95 CN subjects received diffusion tensor imaging and vascular risk evaluation. To properly control normal regional variability of FA, we divided cerebral white matter into 4 strata as measured from a series of young healthy individuals (H1 = highest; H2 = intermediate high; H3 = intermediate low; H4 = lowest anisotropy stratum). RESULTS For overall cerebral white matter, patients with AD had significantly lower FA than CN individuals or patients with MCI in the regions with higher baseline anisotropy (H1, H2, and H3), corresponding to long corticocortical association fibers, but not in H4, which mostly includes heterogeneously oriented fibers. Vascular risk showed significant independent effects on FA in all strata except H1, which corresponds to the genu and splenium of the corpus callosum. Similar results were found within NAWM. FA in WMH was significantly lower than NAWM across all strata but was not associated with diagnosis or vascular risk. CONCLUSIONS Both vascular and Alzheimer disease degenerative process contribute to microstructural injury of cerebral white matter across the spectrum of cognitive ability and have different region-specific injury patterns.

Abstract
Few studies have examined gender differences in hippocampal volumes, and the potential effect of estrogen on these measures has not been well studied. We used MRI to measure hippocampal volumes in elderly Mexican American men and women subjects in order to determine if there were gender differences and if estrogen replacement therapy (ERT) had an effect on hippocampal volume in postmenopausal women. MRI measures of hippocampal volumes (normalized to intracranial volume) were compared in 59 women and 38 men. Further comparisons were made between men subjects, women subjects taking ERT, and women subjects not taking ERT. There were no significant effects of gender on normalized hippocampal volumes. However, women subjects taking ERT had larger right hippocampal volumes than women subjects not taking ERT and larger anterior hippocampal volumes than men subjects and women subjects not taking ERT. These findings suggest a neuroprotective effect of estrogen.

Abstract
Induced pluripotent stem cells (iPSC) offer a unique opportunity for developmental studies, disease modeling and regenerative medicine approaches in humans. The aim of our study was to create an in vitro 'patient-specific cell-based system' that could facilitate the screening of new therapeutic molecules for the treatment of catecholaminergic polymorphic ventricular tachycardia (CPVT), an inherited form of fatal arrhythmia. Here, we report the development of a cardiac model of CPVT through the generation of iPSC from a CPVT patient carrying a heterozygous mutation in the cardiac ryanodine receptor gene (RyR2) and their subsequent differentiation into cardiomyocytes (CMs). Whole-cell patch-clamp and intracellular electrical recordings of spontaneously beating cells revealed the presence of delayed afterdepolarizations (DADs) in CPVT-CMs, both in resting conditions and after β-adrenergic stimulation, resembling the cardiac phenotype of the patients. Furthermore, treatment with KN-93 (2-[N-(2-hydroxyethyl)]-N-(4methoxybenzenesulfonyl)]amino-N-(4-chlorocinnamyl)-N-methylbenzylamine), an antiarrhythmic drug that inhibits Ca(2+)/calmodulin-dependent serine-threonine protein kinase II (CaMKII), drastically reduced the presence of DADs in CVPT-CMs, rescuing the arrhythmic phenotype induced by catecholaminergic stress. In addition, intracellular calcium transient measurements on 3D beating clusters by fast resolution optical mapping showed that CPVT clusters developed multiple calcium transients, whereas in the wild-type clusters, only single initiations were detected. Such instability is aggravated in the presence of isoproterenol and is attenuated by KN-93. As seen in our RyR2 knock-in CPVT mice, the antiarrhythmic effect of KN-93 is confirmed in these human iPSC-derived cardiac cells, supporting the role of this in vitro system for drug screening and optimization of clinical treatment strategies.

Abstract
BACKGROUND/AIMS Hepatitis C virus (HCV) easily undergoes genomic changes, thus accounting for the presence of different genotypes, with different geographic distributions and different outcomes of chronic hepatitis. Type 1b is frequently found in advanced diseases; however, since this genotype is the most prevalent in older patients, the association with advanced age and severity of the disease is confounding. The aim of this study was to assess changes in the prevalence of HCV genotypes by surveying a large population of chronic hepatitis C patients in Northern Italy, and to assess if the high prevalence of genotype 1b in older patients with advanced diseases simply reflects the duration of HCV infection, rather than intrinsic biological properties of HCV. METHODS We studied 1368 HCV-RNA positive patients, with histologically proven chronic hepatitis. Drug addiction, blood transfusions and sporadically acquired infections represented the risk factors. RESULTS Genotype 1b, the most prevalent isolate, and genotype 2a were associated with older age, cirrhosis, sporadically-acquired infections and blood transfusion, while types 1a, 3a, and 4 were associated with younger age, chronic persistent hepatitis and drug addiction. Patients with a history of transfusions were divided into four groups depending on the period of transfusion. The prevalence of genotype 1b decreased with time. Type 3a appeared only after 1979. CONCLUSION The severity of chronic hepatitis C could be related more to the duration of the infection rather than to the intrinsic pathogenicity of HCV genotypes.

Abstract
OBJECTIVE To evaluate the development of myoelectric fatigue in paretic and healthy tibialis anterior muscles of stroke patients. DESIGN Case series. SETTING Occupational therapy and clinical neurophysiology unit. PARTICIPANTS Eight patients with hemiparesis or hemiplegia 9 months to 10 years poststroke. MAIN OUTCOME MEASURES Current pulses of 0.1-ms width and 40-Hz repetition rate were applied for 10 seconds with a monopolar technique; myoelectric signals (M waves) were detected with surface electrodes. RESULTS Mean values and initial values of the median frequency (MDF) between paretic and healthy side were statistically different, with the values on the healthy side much higher than the paretic side. Changes of MDF showed a decreasing pattern for both the paretic and the healthy sides, with the downslope of the curve of the healthy side more evident. CONCLUSIONS In paretic muscles of stroke patients, the tendency toward atrophy of type II fibers appears to be frequent. Our study suggests this muscle rearrangement uses techniques much less invasive than muscle biopsy, and gives useful information about muscle function. This kind of information can help identify rehabilitation strategies, particularly for chronic stroke survivors.

Abstract
Systemic sclerosis (SSc), a multisystem disease involving the microvascular system and the connective tissue, is considered one of the most difficult rheumatic diseases to treat. The natural history of the disease evolves from an edematous to a scleroatrophic phase following two different temporal patterns: acute or chronic. The former leads to early death, and the latter evolves slowly toward severe disability that deserves rehabilitative intervention. Despite the poor prognosis, recent improvements in diagnosis and treatment have led to longer patient survival, thus increasing the need to intervene against the development of tissue fibrosis and contractures by using appropriate integrated rehabilitation programs. This article does not review the medico-pharmacological management of visceral manifestations of the disease. Rather, it is divided into six parts, which include analyses of the changes in skin, joints and tendons, and muscle induced by SSc; examination of the existing literature on rehabilitation strategies and treatments; discussions of the pain and peripheral sensory-motor system involvement that are present to a greater or lesser extent in almost all patients and influence not only the duration and outcome of rehabilitation but also the patient's family, social life, and working ability; and consideration of ergonomic and occupational interventions. No controlled studies have been done on the few rehabilitation guidelines and specific protocols identified, so it must be emphasized that this article is a summary of opinions expressed in the literature and the authors' own findings. Particularly lacking are studies on such aspects as ergonomics, work intervention, or the management of sexual dysfunction. Experience gained in the rehabilitation of skin burns and other rheumatic diseases forms the basis for a logical approach to SSc patients.

Abstract
In the present study, we investigated the frequency of polyneuropathy in a sample of 296 alcoholics who were admitted to the 'S. Maugeri' Medical Centre for detoxification from October 1997 to November 1999. Results revealed a high frequency of polyneuropathy in the sample under study. The disorder was often clinically asymptomatic and demonstrable only on electroneurographic investigation. Significant correlations were found between polyneuropathy, the duration of alcoholism, the type of alcoholic beverage consumed (wine) and the presence of liver disease and macrocytosis.

Abstract
BACKGROUND Neurocognitive and social cognitive impairments represent important treatment targets in schizophrenia, as they are significant predictors of functional outcome. Different rehabilitative interventions have recently been developed, addressing both cognitive and psychosocial domains. Although promising, results are still heterogeneous and predictors of treatment outcome are not yet identified. In this study we evaluated the efficacy of two newly developed social cognitive interventions, respectively based on the use of videotaped material and comic strips, combined with domain-specific Cognitive Remediation Therapy (CRT). We also analysed possible predictors of training outcome, including basal neurocognitive performance, the degree of cognitive improvement after CRT and psychopathological variables. METHOD Seventy-five patients with schizophrenia treated with CRT, were randomly assigned to: social cognitive training (SCT) group, Theory of Mind Intervention (ToMI) group, and active control group (ACG). RESULTS ANOVAs showed that SCT and ToMI groups improved significantly in ToM measures, whereas the ACG did not. We reported no influences of neuropsychological measures and improvement after CRT on changes in ToM. Both paranoid and non-paranoid subjects improved significantly after ToMI and SCT, without differences between groups, despite the better performance in basal ToM found among paranoid patients. In the ACG only non-paranoid patients showed an improvement in non-verbal ToM. CONCLUSION Results showed that both ToMI and SCT are effective in improving ToM in schizophrenia with no influence of neuropsychological domains. Our data also suggest that paranoid symptoms may discriminate between different types of ToM difficulties in schizophrenia.

Abstract
Erythrocyte deformability was studied by the filtration technique of Reid & Dormandy using whole blood and washed erythrocytes from insulin-dependent diabetics (IDD) under insulin delivery by an artificial pancreas (AP). The same technique was employed to study deformability in vitro using normal erythrocytes incubated in the presence of insulin. Results of this study show that in IDD the initially poor erythrocyte deformability is improved within hours of insulin administration. Improved deformability was accompanied by increased levels of intra-erythrocyte ATP but without changes in levels of HbG and 23 DPG. Incubation of erythrocytes in medium containing glucose showed that deformability was significantly improved in the presence of insulin. These results indicate that insulin favourably affects erythrocyte deformability in IDD. Before and after 24 hours treatment by AP, platelet aggregation was studied in IDD by the technique of Born using platelet-rich plasma (PRP) and by a modified Breddin technique using PRP, whole blood or whole blood treated by chlorpromazine and mixtures of erythrocytes from IDD with normal PRP. Platelet hyperaggregation was only found in the presence of erythrocytes from untreated diabetics. Chlorpromazine, at a dose (10 mumole) which inhibits haemolysis without inducing platelet hyperaggregation, eliminated the above anomaly. In conclusion, it is conceivable that the insulin-induced correction of poor erythrocyte deformability eliminates excessive fragility of erythrocytes and their haemolysis wit release of ADP, thus avoiding platelet hyperaggregation.

Abstract
Glutamate is the major excitatory neurotransmitter in the brain, with up to 40% of all synapses being glutamatergic. An altered glutamatergic transmission could play a critical role in working memory deficts observed in schizophrenia and could underline progressive changes such as grey matter loss throughout the brain. The aim of the study was to investigate if gray matter volume and working memory could be modulated by a genetic polymorphism related to glutamatergic function. Fifty schizophrenia patients underwent magnetic resonance and working memory testing outside of the scanner and were genotyped for rs4354668 EAAT2 polymorphism. Carriers of the G allele had lower gray matter volumes than T/T homozygote and worse working memory performance. Poor working memory performance was associated with gray matter reduction. Differences between the three genotypes are more relevant among patients showing poor performance at the 2-back task. Since glutamate abnormalities are known to be involved in excitotoxic processes, the decrease in cortical thickness observed in schizophrenia patients could be linked to an excess of extracellular glutamate. The differential effect of EAAT2 observed between good and poor performers suggests that the effect of EEAT2 on gray matter might reveal in the presence of a pathological process affecting gray matter.

Abstract
Ciguatera poisoning causes mainly gastrointestinal and neurological effects of variable severity. However, symptoms of peripheral neuropathy with paresthesias and paradoxical disturbance of thermal sensation are the hallmark. Electrophysiological studies are often normal, except in severe cases. We report four people who developed mild ciguatera poisoning after barracuda ingestion. Electrophysiological studies documented normocalcemic latent tetany. These findings are consistent with ciguatoxin's mechanism of toxicity, which involves inactivation of voltage-gated Na(+) channels and eventually increases nerve membrane excitability.

Abstract
BACKGROUND Several studies suggested that anxiety can significantly affect the outcome of schizophrenia. Despite this evidence, non-pharmacological interventions targeting anxiety are still heterogenous. This study aims to test the efficacy of a novel training specifically designed to target anxiety in patients with schizophrenia. Innovatively, this training, beyond psychoeducation and problem solving, also targets Theory of Mind, as it provides coping strategies. METHOD Twenty-seven outpatients with schizophrenia received a novel rehabilitative training targeting anxiety (Anxiety Management Group [AMG]) combined with a Computer-Assisted Cognitive Remediation (CACR), and twenty received CACR plus a control intervention (Control Newspaper discussion Group [CNG]). All patients were assessed at baseline and after treatment for quality of life, neurocognition and anxiety. RESULTS After training, patients treated with AMG+CACR showed significantly greater improvements on anxiety. A significant increase in quality of life was observed only for AMG+CACR group. Moreover, the participants' appraisal showed a significant difference between treatment groups with higher ratings among patients who received the AMG+CACR. CONCLUSIONS This study thus suggests feasibility and efficacy of the proposed intervention, that could be implemented in rehabilitative programs for patients with schizophrenia with potential benefits also on disease course and outcome.

Abstract
BACKGROUND Patients with chronic heart failure (CHF) frequently complain of fatigue and exercise intolerance that are not directly related to the severity of cardiac failure. A not well-defined muscle function impairment is generally considered the cause of such symptoms. The frequency compression of electromyographic (EMG) signal power spectrum during isometric contractions is commonly accepted as an index of the fatigue occurring in the muscle (localized muscle fatigue). PURPOSE AND METHODS The purpose of the study was to evaluate muscle fatigue development in a selected group of CHF patients by studying the compression of the EMG signal power spectrum. The first dorsal interosseus of the right, dominant hand was investigated at two levels of contraction: 40% and 80% of the maximal voluntary contraction (MVC). RESULTS In CHF patients there was early development of localized muscle fatigue during the high level of contraction (80% of MVC). CONCLUSION This study demonstrates the presence of an early development of localized muscle fatigue in CHF patients and confirms the possibility of an increased glycolytic metabolism. Moreover, the changes seem to show that muscle impairment is not limited to large muscles, but also occurs in small muscles of the hands, frequently used during daily activities. Finally, this study confirms the validity of EMG spectral analysis techniques in evaluating muscle fatigue of CHF patients, suggesting a possible use in the rehabilitation of such patients when the technique is correctly used.

Abstract
Spasticity is one of the major problems affecting the outcome of rehabilitation in paraplegic patients. Orphenadrine citrate possesses an effective muscle relaxant action in many pathologies. Nevertheless, despite a recognized central site of action, no controlled data are available on its use in the treatment of spastic hypertonia in patients with spinal cord injuries. Therefore, the effect of intravenous administration of 60mg of orphenadrine citrate versus placebo on spastic hypertonia after spinal cord injury was studied in 11 patients. The threshold of the flexion reflex of the lower limb was studied as a neurophysiological correlate of spastic hypertonia. Clinical assessment was made using the Ashworth Spasticity Scale. The threshold, expressed in mAmp, was studied for 60 minutes after the treatment. A significant difference was found using the active drug compared with placebo (p < 0.0001). In 9 patients, the reduction of the abnormal flexion responses after orphenadrine appeared to begin only after 30 minutes. In one patient the onset of the therapeutic effect was early but weak. One patient with severe spastic hypertonia leading to triple flexion when the limb was manipulated did not gain any relief with orphenadrine. The clinical and neurophysiological results suggest an efficacy of orphenadrine citrate in the control of spastic hypertonia in paraplegics. This could be relevant in the rehabilitation strategy, although further studies are needed on the duration of its action.

Abstract
The authors determined whether a sufficient amount of intravenously administered gadolinium enters the cerebrospinal fluid (CSF) to visibly shorten the T1 relaxation time. Transfer of intravenously administered contrast media into the CSF has been previously documented for iodinated contrast materials; however, the change in computed tomography density is not sufficient to have a clinically useful myelographic effect. Visible shortening of the T1 of CSF on gadolinium-enhanced magnetic resonance imaging of the spine may have clinical use. Twelve dogs were given gadolinium, and CSF was sampled at intervals over a 6-hour period. The T1 values of the CSF samples were quantitated and plotted against time. The average decrease in T1 was 23% at 60 minutes, which is nearly the peak effect. The increased signal intensity was visible at clinical window settings at 60 minutes. It is possible that this may be clinically useful for certain types of examinations. Importantly, this should be recognized as a normal appearance, and not necessarily a sign of pathology.

Abstract
Appropriate measurement of maximal voluntary contraction force of a single limb muscle or of a muscle group is important in clinical and research situations. To measure muscle force, one segment of an isometric measuring brace is fixed to a support and force is applied to the other. The output of this arrangement is affected by additional contributions such as pushing or pulling with the whole body. This paper quantifies the differences between measurements of torque produced by the biceps brachii with the brace fixed versus those produced when the elbow joint was isolated by suspending the brace from cables. No statistically significant differences were found between MVC values observed with the two methods within subjects. However, a statistically significant difference in EMG fatigue indices was observed and attributed to a different sharing of force production among different muscles in the two conditions. We conclude that different brace arrangements may lead to the same maximal force but to different rates of myoelectric manifestations of muscle fatigue since the effort may be shared differently among the muscles of synergic or stabilizing groups.

Abstract
Shunt malfunction is common and its diagnosis may require invasive testing that may be inaccurate or result in complications. Magnetic resonance imaging (MRI) may prove to be a useful noninvasive test of shunt function as it has been shown that MRI is capable of measuring cerebrospinal fluid (CSF) flows from 2 ml/h to 40 ml/h in model systems. Since flows in functioning shunt systems can be less than 2 ml/h, MRI must be sensitive enough to detect flow in this range in order to be a valid test for shunt function. Continuing previous studies, we have studied MRI flow-related enhancement at flow rates from 0 to 2 ml/h. Multiple spin echo scans (TR2000, TE20) were made through a specialized section of tubing in a model shunt system. The intensity of the MRI signal at points known to demonstrate maximal flow-related enhancement was measured. A linear relationship was demonstrated between signal intensity and flow as low as 0.8 ml/h. These results add support to the concept that MRI is sensitive enough to detect the lowest flows present in functioning shunt systems and therefore may be useful as a noninvasive test of shunt function.

Abstract
Peripheral arterial disease (PAD) patients are commonly classified on the basis of subjective evaluations of pain and fatigue. Surface electromyography (EMG) is an objective method for studying peripheral muscle fatigue. Fifteen patients with PAD and 15 healthy volunteers matched for age and sex were studied. Surface EMG was recorded over the medial gastrocnemius during 100 seconds at 60% of maximal effort. EMG traces were analyzed off-line to obtain the power spectrum. The median frequency was calculated in the first 30 seconds (T0) and between 70 and 100 seconds (T1). Significantly lower T1 values, compared with T0, were found in both the PAD and the control groups (p < .005; p < .05). T0 values were not different between group, whereas T1 values were significantly lower in PAD patients (p < .01). EMG frequency analysis can be considered an easy, painless method providing objective information on muscular performance and fatigue in PAD patients.
