Abstract
The aim of this study was to investigate that inter-arm blood pressure (BP) difference (IAD) and reference arm in 420 post-stroke patients with hemiparesis. Synchronous bilateral-arm BP was measured with two automatic BP devices, and the systolic BP difference of ≥10 mm Hg was recorded as increased sIAD. The arm with higher systolic BP (SBP) was assigned as the reference arm. Our results showed that the prevalence of sIAD was 18.1% in the total group. The paretic arms had similar mean SBP levels (133.6±18.4 vs. 133.8±18.4 mm Hg, NS) and DBP (77.8±11.5 vs. 77.2±10.9 mm Hg, NS) as compared with the unaffected arms. The detection rate of hypertension or uncontrolled hypertension on the SBP values of the reference arm was higher than that on the unaffected arm (41.8% vs. 36.3%). It is concluded that in the post-stroke patients with hemiparesis in the rehabilitation period, the prevalence of sIAD ≥10 mmHg was relatively higher, and using the unaffected arm, rather than the unaffected arm, for BP measurement could induce correctly detection of hypertension.

Abstract
PURPOSE An intermediate cervical plexus block (CPB) targets the posterior cervical space between the sternocleidomastoid muscle and the prevertebral fascia. The phrenic nerve descends obliquely on the surface of the anterior scalene muscle beneath the prevertebral fascia after originating from the C3-C5 ventral rami. Therefore, the phrenic nerve can be affected by a local anesthetic during an intermediate CPB, depending on the permeability characteristics of the prevertebral fascia. This study investigated whether an intermediate CPB affects the phrenic nerve, inducing hemidiaphragmatic paresis. METHODS In this prospective observational study, 20 patients undergoing single-incision transaxillary robot-assisted right thyroidectomy were enrolled. The intermediate CPB (0.25% ropivacaine 0.2 ml/kg) was performed at the C4-5 intervertebral level carefully, without penetrating the prevertebral fascia, before the patient emerged from general anesthesia. Diaphragmatic motions of the block side were measured by M-mode ultrasonography at three time points: before anesthesia (baseline) and at 30 and 60 min after the intermediate CPB. Hemidiaphragmatic paresis was divided into three grades, depending on the percentage of diaphragm movement compared to the baseline: none (> 75%), partial paresis (25-75%), and complete paresis (< 25%). RESULTS No patient showed any partial or complete ipsilateral hemidiaphragmatic paresis within 60 min after the intermediate CPB. CONCLUSION Intermediate CPB using 0.2 ml/kg of 0.25% ropivacaine at the C4-5 intervertebral level did not cause ipsilateral hemidiaphragmatic paresis. This may imply that the effect of the intermediate CPB on the phrenic nerve is not significant.

Abstract
BACKGROUND The goal of the present study is the evaluation of the long-term clinical outcome of epilepsy in patients with mesial temporal lobe sclerosis (MTLS) submitted to amygdalohippocampotomy (AHCo). AHCo consists of the lateral ablation of the amygdala and the peri-hippocampal disconnection instead of amygdalohippocampectomy (AHC), which involves the removal of both structures. We previously reported the short-term results of AHCo, so we here present the long-term results (> 5 years of follow-up) of the patients operated on with AHCo. METHOD Since 2007, 35 patients (22 females) aged 20-61 years (mean: 42 years) were operated on with the AHCo technique, 17 patients on the left side and 18 on the right. Of these patients, 21 (14 females) have been followed up > 5 years (5 to 7.5 years, mean 6.5 years). We compare the present results with those observed shortly after surgery and with the patients operated on with AHC. FINDINGS In all 21 cases, the diagnosis was mesial temporal lobe sclerosis (histology confirmed in 20), 11 on the left side and 10 on the right. Epilepsy results after 5 years were good/very good in 18 patients (85.7%), with Engel class IA-B in 15 (71.4%) and II in 3 (14.3%), and bad in 3 patients, with Engel Class III in 2 (9.5%) and class IV in 1 (4.8%). Concerning morbidity, one patient had hemiparesis (hypertensive capsular hemorrhage 24 h after surgery), two verbal memory worsening, two quadrantanopia and three late depression that was reversed with medication. Comparatively, the AHC long-term results were 87% Engel class I, 8% Engel class II and 5% Engel class III-IV. The morbidity was equally small. CONCLUSIONS The good/very good results of AHCo 5 years after surgery are 86%, which is not distinct from the AHC results. So AHCo seems to be effective and potentially safer than AHC in long-term follow-up.

Abstract
BACKGROUND In this single-center study, we sought to determine the frequency of phrenic nerve injury leading to diaphragm paresis (DP) in children following open cardiac surgery over the last 10 years, and to identify possible variables that predict the need for plication and associated clinical outcomes. METHODS Patients diagnosed with DP were identified from departmental databases and a review of clinical diaphragm ultrasound images. A cohort was analyzed for predictors of diaphragm plication and associations with clinical outcomes. Cumulative proportion graphs modeled the association between plication and length of stay. RESULTS DP was diagnosed in 161 of 6448 patients (2.5%) seen between January 2002 and December 2012. All diagnoses but 1 were confirmed by ultrasound. Plication of the diaphragm was performed in 30 patients (19%); compared with patients who did not undergo plication, these patients were younger (median age, 10 days vs 138 days; P < .001), more likely to have undergone deep hypothermic circulatory arrest (47% vs 18%; P = .005), had a longer duration of positive pressure ventilation (median, 15 days vs 7 days; P < .001), and had longer lengths of stay in both the intensive care unit (median, 23 days vs 8 days; P < .0001) and the hospital (median, 37 days vs 15 days; P < .0001). Early plication was associated with reduction in all intervals of care. CONCLUSIONS Early plication should be considered for patients with diaphragm paresis requiring prolonged respiratory support after cardiac bypass surgery. Longer follow-up evaluation is required to better define the long-term implications of plication.

Abstract
BACKGROUND AND PURPOSE A significant number of stroke survivors will not recover the use of their affected arm. A proportion will experience pain, stiffness and difficulty with basic care activities. The purpose of the review was to identify predictors of difficulty caring for the profoundly affected arm and establish the incidence and time-course of the related impairments of pain, spasticity and contracture. METHOD Data sources: Databases (PubMED, MEDLINE, AMED, EMBASE, CINAHL and the Cochrane Controlled Trials Register) were searched from inception to December 2013. Additional studies were identified from citation tracking. REVIEW METHODS Independent reviewers used pre-defined criteria to identify eligible studies. Quality assessment and risk of bias were assessed using the McMasters Assessment Tool. A narrative evidence synthesis was performed. RESULTS Thirty-nine articles reporting 34 studies were included. No studies formally measured difficulty caring for the arm, but related impairments were common. Incidence of spasticity in those with weakness ranged from 33% to 78%, shoulder pain affected 22% to 90% and contracture was present in at least 50%. Spasticity and pain appear within 1 week of stroke, and contracture within two weeks. Impairments continued to develop over at least 3-6 months. The most frequent predictors of spasticity and contracture were weakness and reduced motor control, and the risk of pain is most commonly predicted by reduced sensation, shoulder subluxation, weakness and stroke severity. DISCUSSION There is no published evidence on predicting the likelihood of difficulty caring for the arm following stroke. However, the related impairments of spasticity, pain and contracture are common. Given the time-course of development, clinicians may need not only to intervene early but also be prepared to act over a longer time period. Further research is needed to examine difficulty caring for the arm and the relationship with associated impairments to enable researchers and clinicians to develop targeted interventions. © 2015 The Authors.

Abstract
INTRODUCTION Chronic subdural hematoma is an intracranial hemorrhagic lesion that illustrates various expressions in clinical and radiological practice. The aim of this study was to emphasize the correlation between the brain site of chronic subdural hematoma and clinical symptoms/signs of disease. Furthermore, the study denotes the significance of hemiparesis occurrence in the patients with unilateral chronic subdural hematomas more than in those with bilateral ones, associated with time required to diagnose hematoma. MATERIAL AND METHODS A three-year study included 72 patients with chronic subdural hematoma. According to their clinical and neurological symptoms on hospital admission, all patients underwent non-contrast brain computed tomography scan, which confirmed the diagnosis. The radiological parameters, including the site of chronic subdural hematoma, a hematoma width and midline shift were recorded to give precise data about the correlation with neurological symptoms. A special focus was put on the lag time between the onset of symptoms and signs to diagnosis of chronic subdural hematoma. RESULTS The study proved that the patients with unilateral chronic subdural hematoma had more frequent occurrence of hemiparesis than the patients with bilateral chronic subdural hematoma. It took the left-sided chronic subdural hematomas less time (about 200 hours earlier) than the right-sided ones to present its symptoms although the average hematoma diameter value was almost the same. CONCLUSION The site and the form of intracranial lesion-chronic subdural hematoma could have a great influence on neurological and functional condition in a patient. Although the length of time required for making diagnosis as well as clinical symptoms greatly differ and the latter are not always so clear, physicians should maintain a high level of suspicion for this disease and thus contribute to prompt diagnosis and better clinical outcome of patients.

Abstract
OBJECTIVE To review the clinical manifestations and neuroimaging features of patients with Sturge-Weber syndrome (SWS) treated at Srinagarind Hospital over a 12-year period. MATERIAL AND METHOD A retrospective study of sixteen patients with SWS (9 males and 7 females) was conducted. The medical records, photographs, and neuroimaging studies were reviewed RESULTS All patients had port-wine stain (PWS) involving the eyelid. Bilateral cutaneous lesions were revealed in four patients (25%). Glaucoma was the main ocular disease being diagnosed in 11 eyes of nine patients (56.25%); four eyes were finally blind. The cyclodestructive procedure and/or surgical treatment was required in four eyes. Other ocular abnormalities were refractive error dilated episcleral vessels, corneal abnormalities, tortuous retinal vessels, choroidal hemangioma, amblyopia, and strabismus. Twelve patients (75%) had neurological impairment including seizure, hemiparesis, headache, and delayed development. However the most common neurological manifestation was epilepsy (75%), which could be controlled with antiepileptic drugs. Neurological imaging was performed in the majority of cases (14 patients). Intracranial abnormalities were demonstrated in 11 patients (78.57%). These included cerebral atrophy (81.82%), cerebral calcification (54.55%), leptomeningeal angioma (27.27%), and enlarged choroidal plexus (27.27%). The ocular complication and intracranial abnormalities were usually ipsilateral to the PWS. One patient with unilateral PWS, however had bilateral intracranial lesion. CONCLUSION Port-wine stains, glaucoma, and seizure were the most common clinical features of Sturge-Weber syndrome detected in the present study. Complete ophthalmic and neurological evaluation should be performed at the time ofdiagnosis. Multidisciplinary team management as well as lifelong follow-up is needed.

Abstract
OBJECTIVES The apolipoprotein E gene (APOE) polymorphism may influence outcome in various forms of brain injury. The association between APOE genotype and long-term ischemic stroke (IS) outcome is controversial. We have examined the effect of stroke risk factors, clinical status at admission and APOE genotype on survival and dependency 1 year after IS. METHODS We investigated 496 consecutively subjects with IS. Information concerning risk factors and clinical data were collected prospectively. Functional dependency was estimated with modified Rankin scale (mRS) and defined as a score of 3-5. Each patient was offered a I year follow-up evaluation. APOE genotyping was performed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Multivariate regression models were used to analyse predictors of death and poor outcome (death or dependency) within 1 year after the stroke. RESULTS The distribution ofAPOE genotypes was 69% with genotype E3/E3, 18% with genotype F3/ E4, 12% with genotype E2/13 and 1% with genotype F2/14. At year 1, 169 patients (38%) had died and 78 of the survivors (28%) were functionally dependent. The best predictors of death at year 1 were: age over 70 years, congestive heart failure, atrial fibrillation, disturbed consciousness and severe hand paresis. Poor outcome was independently predicted by: age over 70 years, congestive heart failure, pre-stroke mRS> or =3, marked disturbance of consciousness and severe hand paresis. CONCLUSION We did not find any impact of APOE genotype on mortality or poor outcome 1 year after IS.

Abstract
BACKGROUND Postoperative complications are integral to cardiac surgery. The most serious ones are stroke, which develops in about 7.5% of the patients, and postoperative encephalopathy, which affects 10-30% of the patients. According to bibliographical data, the number of complications is increasing. AIM To analyse the risk factors and the types of neurological complications in patients undergoing heart surgery. METHODS We assessed retrospectively 323 consecutive patients undergoing surgery at the Department of Cardiac Surgery, University Teaching Hospital, Medical University of Bialystok, Poland, between July 2007 and June 2008. Group 1 comprised patients without neurological complications (n = 287; 89%) and Group 2 consisted of patients with neurological complications (n = 36; 11%). Our analysis included the following: preoperative status (age, sex, co-morbidities), intraoperative course (surgery type, duration of cardiopulmonary bypass [CPB], duration of aortic cross-clamping, types of medications administered, necessity of reinfusion from the cardiotomy reservoir and the necessity of tranexamic acid infusion) and the postoperative course (time to regaining consciousness, duration of mechanical ventilation, development of complications, types of complications). The results were then analysed statistically: arithmetic means and standard deviations were calculated for quantitative variables and the quantitative and percentage distributions were calculated for qualitative variables. The between- group comparisons of the quantitative variables were carried out using the t-Student test, while the qualitative variables were compared using the χ(2) test. The variables that proved significant in the univariate comparisons were included in the multivariate model. Regression analysis was the final step of the analysis of the risk factors for neurological complications. Based on the analysis of the ROC curve we calculated the cutoff values for the continuous variables. We calculated odds ratios with their 95% confidence intervals. P values of less than 0.05 were considered statistically significant. RESULTS Among the 36 patients in Group 2, postoperative encephalopathy developed in 22 patients, transient ischaemic attacks in 7 patients, ischaemic stroke in 6 patients (associated with right hemisphere damage in 3 patients and with left hemisphere damage in 3 patients) and haemorrhagic stroke in 1 patient (right hemisphere). Early mortality was 5% with 2 (0.69%) patients dying in Group 1 and 14 (38.9%) in Group 2. Univariate analysis revealed that the preoperative risk factors of neurological complications were: age >68 years (with a cutoff value of 58.5 years), a history of stroke with paresis, atrial fibrillation (AF) and a euroSCORE of >6 (with a cutoff value of 4.5). The peri- and postoperative risk factors included: surgery type (complex coronary and valvular surgeries aortic valve surgeries), duration of CPB of >142 min, duration of aortic crossclamping of >88 min, mean perfusion pressure during CPB of <70 mm Hg, haemodilution manifested by a haematocrit (HCT) of <28%, perfusate supply, time to regaining consciousness of >14.5 h and duration of artificial ventilation of >30.5 h. Multivariate analysis revealed the following factors to increase the risk of neurological complications: long duration of ventilation, a history of stroke with paresis, AF, low HCT values and long duration of aortic cross-clamping. The Nagelkerke R2 coefficient of determination was 0.636, the sensitivity was 74.36%, the specificity was 97.545% and the accuracy was 94.74%. CONCLUSIONS In patients undergoing heart surgery, the independent risk factors of neurological complications in the first 30 days include: long duration of ventilation, a history of stroke with paresis, AF, haemodilution manifested by an HCT of <28% and long duration of aortic cross-clamping. Neurological complications are associated with high postoperative mortality.

Abstract
Dengue infection has been implicated as a cause of neurologic manifestations since the beginning of the 20th century. An enhanced surveillance system for encephalitis and aseptic meningitis developed by the Puerto Rico Department of Health in collaboration with the Dengue Branch, Centers for Disease Control and Prevention, identified eleven laboratory positive dengue patients presenting with neurologic manifestations in 2003. Anti-dengue IgM antibody was detected in serum of eight patients and in cerebrospinal fluid of one patient. DENV-2 and DENV-3 were isolated from the serum of one patient each. All patients were negative for serologic markers of West Nile Virus and St. Louis encephalitis. Nine (82%) of the 11 patients had symptoms compatible with encephalitis. Their median age was 46 years (range: 9 months - 82 years) and five were males. Symptoms included severe headache, seizures, altered mental status, confusion, and coma. A motor disorder (upper extremities weakness and Guillain Barré Syndrome, respectively) occurred in two additional patients. Most patients recovered but there were two fatalities. Neurologic manifestations of dengue were rarely reported in Puerto Rico until the institution of enhanced surveillance, which resulted in the recognition of severe and fatal cases.

Abstract
BACKGROUND Obstetric brachial plexus palsy is rare, but the limb impairments are manifold and often long-lasting. Physiotherapy, microsurgical nerve reconstruction, secondary joint corrections, and muscle transpositions are employed with success. The role of conservative and operative treatment options should be regularly reviewed. METHODS Selective literature review (evidence levels 3 and 4) and analysis of personal clinical operative and scientific experience over the past 15 years. RESULTS Children with upper and total plexus palsy displaying nerve root avulsions and/or -ruptures are treated today by early primary nerve reconstruction in the first few months of life followed by secondary corrections, with good functional results. The late complications, with muscle weakness, impaired motion patterns, and joint dysplasia, are often underrated. CONCLUSIONS The potential for scientific analysis is limited, due to the rarity and interindividual variability of the lesions and the varying effects on function and growth. Expectations and compliance are different in every patient. Surgical techniques are not yet standardized. Knowledge of the consequences for joint growth and congruence is inadequate. Today, functional improvement can be achieved by surgery in most clinical manifestations of obstetric brachial plexus palsy, within the framework of an interdisciplinary treatment concept.

Abstract
OBJECTIVE Sporadic acoustic neuroma, usually occur between the ages of 40 and 70 years, are very rare in children. We review the experiences of 10 cases of sporadic (non-NF2) acoustic neuromas in pediatric patients. METHOD During last 26 years 2000 skull base procedures were performed in the Otorhinolaryngology Unit of the Ospedali Riuniti di Bergamo. Among these almost 900 cases were acoustic neuromas. Only 10 were at or under the age of 18 years. RESULTS The age of the youngest patient in our series was 12 years. Deafness were the commonest presentation and were seen in eight patients. It varied between 10 and 65 dB sensorineural hearing loss. Among these eight cases, two patients have sudden onset of hearing loss. Two patients presented with dizziness. The duration of complaints were between 2 months and 5 years in these patients. The diameter of the tumors varied widely with minimum of 10 mm to maximum up to 60 mm. Five patients each underwent resection of the tumor by translabyrinthine and retrosigmoid approach, respectively. The minimum postoperative follow-up was 3 years and maximum was 22 years in our series. Postoperatively seven cases the facial nerve recovered to grade I, and one each to grade II and grade VI of House-Brackmann classification. All five cases who underwent retrosigmoid approach had moderate (40 dB) to total sensorineural hearing loss postoperatively. The youngest patient with largest tumor diameter of 60 mm developed transient hemiparesis in the immediate postoperative period and he recovered fully in due course. CONCLUSION We found preservation of facial nerve function is more easier than hearing in this group of patients.

Abstract
BACKGROUND Motor recovery after stroke is predicted only moderately by clinical variables, implying that there is still a substantial amount of unexplained, biologically meaningful variability in recovery. Regression diagnostics can indicate whether this is associated simply with Gaussian error or instead with multiple subpopulations that vary in their relationships to the clinical variables. OBJECTIVE To perform regression diagnostics on a linear model for recovery versus clinical predictors. METHODS Forty-one patients with ischemic stroke were studied. Impairment was assessed using the upper extremity Fugl-Meyer Motor Score. Motor recovery was defined as the change in the upper extremity Fugl-Meyer Motor Score from 24 to 72 hours after stroke to 3 or 6 months later. The clinical predictors in the model were age, gender, infarct location (subcortical vs cortical), diffusion weighted imaging infarct volume, time to reassessment, and acute upper extremity Fugl-Meyer Motor Score. Regression diagnostics included a Kolmogorov-Smirnov test for Gaussian errors and a test for outliers using Studentized deleted residuals. RESULTS In the random sample, clinical variables explained only 47% of the variance in recovery. Among the patients with the most severe initial impairment, there was a set of regression outliers who recovered very poorly. With the outliers removed, explained variance in recovery increased to 89%, and recovery was well approximated by a proportional relationship with initial impairment (recovery congruent with 0.70 x initial impairment). CONCLUSIONS Clinical variables only moderately predict motor recovery. Regression diagnostics demonstrated the existence of a subpopulation of outliers with severe initial impairment who show little recovery. When these outliers were removed, clinical variables were good predictors of recovery among the remaining patients, showing a tight proportional relationship to initial impairment.

Abstract
BACKGROUND AND PURPOSE There are not very many epidemiological studies on perinatal stroke, and many authors suggest that this may be an underdiagnosed condition. The aim of the study was to estimate the incidence of perinatal arterial ischemic and hemorrhagic stroke in Estonia, to study the first clinical signs and to identify possible differences in predisposing factors and outcome between acutely and retrospectively diagnosed cases of perinatal stroke. METHODS A retro- and prospective study of acutely (within the first month) and retrospectively diagnosed ischemic and hemorrhagic cases of perinatal stroke was conducted in a children population born in the eastern and southern regions of Estonia during the years 1994 to 2003. Patients were identified from a pilot study, hospital records, and an inquiry of child neurologists and general practitioners. The diagnosis was confirmed in 38 (12 were diagnosed acutely and 26 retrospectively) cases by neuroradiology (MRI or CT). RESULTS The incidence rate of perinatal stroke in Estonia is 63 per 100,000 live births. Main clinical findings in the neonatal period were seizures, abnormalities of muscular tone, and disturbed level of alertness. Previously identified risk factors occurred in 32% of cases. Children with early diagnosis had more often adverse events during pregnancy and delivery (P<0.05) and developed more severe stage of hemiparesis compared with children with late diagnosis (P<0.05). CONCLUSIONS The incidence rate of 63 per 100,000 live birth is higher than previously reported. Detailed analysis of the first signs of perinatal stroke may improve the early diagnostics of perinatal stroke.

Abstract
OBJECTIVE To conduct a large population-based survey on multiple sclerosis (MS) prevalence in Shanghai, China. METHODS We established a network of physicians, mainly neurologists, for identifying prevalent patients with MS and systematically checked inpatient registers at each hospital in the study area for patients with a diagnosis of MS, neuromyelitis optica, or other demyelinating disorders. MS diagnosis in patients was validated by senior neurologists according to the McDonald criteria. RESULTS In total, 123 patients with a validated MS diagnosis from the study population, 8.86 million inhabitants with permanent residence in Shanghai, were alive on the prevalence day. The crude MS prevalence rate was 1.39 cases per 100,000 inhabitants (95% CI: 1.16 to 1.66 cases) in the study population in Shanghai. There were 79 female and 44 male patients with MS, a female-to-male ratio of 1.8. Nearly all (96%) of the patients with validated MS had been examined by MRI. CONCLUSION Multiple sclerosis prevalence in Shanghai is in line with that reported for other Asian populations.

Abstract
To describe the clinical characteristics of haemorrhagic pure motor stroke (PMS). Twelve patients with haemorrhagic PMS were identified. Haemorrhagic PMS accounted for 3.2% of all cases of pure motor hemiparesis (n = 380) and 3.3% of intracerebral haemorrhage (n = 364) entered in the database. When compared with PMS of ischaemic origin, patients with haemorrhagic PMS were more likely to be younger (62.2 vs. 75.2 years, P = 0.003) and to have headache (33% vs. 6.3%, P =0.007) and thalamus involvement (25% vs. 2.4%, P = 0.005). Limb weakness (100% vs. 74.1%; P = 0.03), involvement of the internal capsule (50% vs. 17.3%, P = 0.012) and symptom free at discharge (25% vs. 3.7%, P = 0.012) were significantly more frequent in patients with haemorrhagic PMS than in the remaining cases of haemorrhagic stroke, whereas nausea and vomiting (0% vs. 25.9%, P = 0.03), altered consciousness (0% vs. 42.9%, P = 0.001), sensory symptoms (8.3% vs. 46.9%, P =0.007) and ventricular haemorrhage (0% vs. 26.1%, P = 0.028) were significantly less frequent. Haemorrhagic PMS is a very infrequent stroke subtype. Headache at stroke onset may be useful sign for distinguishing haemorrhagic PMS from other causes of lacunar stroke. There are important differences between haemorrhagic PMS and the remaining intracerebral haemorrhages.

Abstract
BACKGROUND There is no consensus concerning the presence of spasticity or the relationship between spasticity and functioning and spasticity and health-related quality of life (HRQL) in the stable phase after stroke. OBJECTIVE The aim of the present study was to describe, 18 months after stroke, the frequency of spasticity and its association with functioning and HRQL. METHODS In a cohort of 66 consecutive patients with first-ever stroke, studied prospectively, the following parameters were assessed 18 months after stroke: spasticity, by the Modified Ashworth Scale (0-4 points with 1+ as the modification), muscle stiffness, by self-report, abnormal tendon reflexes, by physical examination, motor performance, by the Lindmark Motor Assessment Scale, mobility, by the Rivermead Mobility Index, activities of daily living, by the Barthel Index, and HRQL, by the Swedish Short Form 36 Health Survey Questionnaire (SF-36). RESULTS Of 66 patients studied, 38 were hemiparetic; of these, 13 displayed spasticity, 12 had increased tendon reflexes, and 7 reported muscle stiffness 18 months after stroke. Weak (r < 0.5) to moderate (r = 0.5-0.75) correlations were seen between spasticity and functioning scores. Correlations between spasticity and HRQL were generally weak (r < 0.5). Hemiparetic patients without spasticity had significantly better functioning scores and significantly better HRQL on 1 of the 8 SF-36 health scales (physical functioning) than patients with spasticity. CONCLUSIONS Few patients displayed spasticity 18 months after stroke. Spasticity might contribute to impairment of movement function and to limitation of activity, but seems to have a less pronounced effect on HRQL.

Abstract
OBJECTIVES The clinical diagnosis of Kennedy's disease (KD) is not easy when the typical manifestations are lacking, especially in early stage of the disease. In our study, we tried to identify the relative frequency of common clinical features and early symptoms in KD. METHOD Eighteen Korean patients with KD were included. Clinical findings were subdivided into two parts: the age at onset of each clinical symptoms and characteristic signs on investigations. With detailed clinical examinations, the serum creatine kinase (CK) level, electrophysiologic study and DNA analysis were performed and analyzed in detail. RESULTS In KD, the most consistent clinical findings at evaluations included perioral fasciculation with variable bulbar paresis, limb weakness with wasting, hyporeflexia, hand tremor, and elevated CK level. Some distinguishing features, such as X-linked family history, gynecomastia, and sensory abnormalities were absent in a half of cases. Frequent initial clinical findings include tremor (50%) and symptoms other than weakness, such as cramps and fatigability (33.3%). CONCLUSION We conclude that KD shows variable clinical and electrophysiological features. Our description on the onset and subsequent progression of each clinical finding might help to identify KD in early stage and avoid misdiagnosis.

Abstract
OBJECTIVE To analyze how the patient himself perceives his physical and social situation 1 year after Guillain-Barre syndrome (GBS). MATERIAL AND METHOD The Dutch patients who participated in an international multicenter trial were asked to complete a self-administered questionnaire containing questions on their physical status at homecoming and at 12 months, as well as questions dealing with various aspects of their social condition. RESULTS Ninety patients participated. Up to 72% had sensory disturbances and loss of power in part of the arms and up to 89% in part of the legs at homecoming. At 12 months, a significant improvement had occurred, but residua were perceived in 36 and 67%, respectively. The residua ranged from irritating to seriously disturbing in up to 49%, and only 33% felt completely cured. Furthermore, 32% had changed their work due to GBS, 30% did not function at home as well as before and 52% had altered their leisure activities. CONCLUSION One year after the onset of GBS, a considerable number of patients still perceived a decrease of power and sensation with an often disturbing effect. GBS had an evident impact on daily life and social well-being.

Abstract
OBJECTIVE Meningiomas arising from the petroclival region remain a challenging surgical problem. Because of the substantial risk of neurological morbidity, uniformly pursuing a gross total resection (GTR) to minimize tumor recurrence rates may not be justified. We sought to define optimal resection goals based on risk factors for postoperative neurological morbidity and tumor recurrence rates. METHODS This series represents our experience with 137 meningiomas arising from the petroclival region resected between June 1993 and October 2002. There were 38 male and 99 female patients with a mean age of 53 years. RESULTS GTR was achieved in 40% of patients, and near total resection (NTR) was achieved in 40% of patients. One operative death occurred. Twenty-six percent of patients experienced new postoperative cranial nerve deficits, paresis, or ataxia when assessed at a mean follow-up of 8.3 months. The risk of cranial nerve deficits increased with prior resection (P < 0.001), preoperative cranial nerve deficit (P = 0.005), tumor adherence to neurovascular structures (P = 0.046), and fibrous tumor consistency (P = 0.005). The risk of paresis or ataxia increased with prior resection (P = 0.001) and tumor adherence (P = 0.045). Selective NTR rather than GTR in patients with adherent or fibrous tumors significantly reduced the rate of neurological deficits. Radiographic recurrence or progression occurred in 17.6% of patients at a mean follow-up of 29.8 months. Tumor recurrence rates after GTR and NTR did not differ significantly (P = 0.111). CONCLUSION Intraoperatively defined tumor characteristics played a critical role in identifying the subset of patients with an increased risk of postoperative deficits. By selectively pursuing an NTR rather than a GTR, neurological morbidity was reduced significantly without significantly increasing the rate of tumor recurrence.

Abstract
OBJECTIVE Critical illness polyneuropathy/myopathy (CIP/CIM) is frequently described in critically ill patients who survive severe sepsis. Clinically relevant paresis is major symptom of CIP/CIM. We aimed at determining risk factors and diagnostic value of electrophysiologic testing for CIP/CIM in patients with acute respiratory distress syndrome (ARDS). DESIGN Single-center, retrospective analysis, using charts. SETTING University medical center. PATIENTS Fifty consecutive ARDS patients in our intensive care unit. INTERVENTIONS Patient characteristics and clinical course were analyzed. All patients received early electrophysiologic testing. CIP/CIM was diagnosed by the presence of clinical relevant paresis. MEASUREMENTS AND MAIN RESULTS Clinically relevant paresis was confirmed in 27 ARDS patients (60%), whereas in 18 patients no paresis was determined (controls); five patients died before clinical assessment of paresis was feasible. Patients with paresis were older, had more days on mechanical ventilation, and had increased intensive care unit length of stay compared with controls. Patients who developed paresis had elevated daily peak blood glucose levels during 28 days of intensive care unit treatment: 166 (134, 200) mg/dL in CIP/CIM patients vs. 144 (132, 161) mg/dL in controls (median, quartiles). Twenty-five of 27 patients with paresis revealed reduced motor unit potentials, fibrillation potentials, or positive sharp waves on early electrophysiologic testing indicating CIP/CIM, whereas 16 of 18 control patients did not. CONCLUSIONS In ARDS patients, paresis is a frequent complication causing prolonged mechanical ventilation and intensive care unit length of stay. An association between hyperglycemia and CIP/CIM has been found. However, since this is a retrospective survey, a causal relation is not clearly supported. In this study, the use of early electrophysiologic testing in ARDS patients was a valuable diagnostic tool for detecting CIP/CIM.

Abstract
BACKGROUND In previous studies, the incidence of anosognosia for hemiparesis has varied between 17% and 58% in samples of brain damaged patients with hemiparesis. OBJECTIVE To determine whether this wide variation might be explained by the different criteria used for diagnosing anosognosia. METHODS 128 acute stroke patients with hemiparesis or hemiplegia were tested for anosognosia for hemiparesis using the anosognosia scale of Bisiach et al. RESULTS 94% of the patients who were rated as having "mild anosognosia"-that is, they did not acknowledge their hemiparesis spontaneously following a general question about their complaints-suffered from, and mentioned, other neurological deficits such as dysarthria, ptosis, or headache. However, they immediately acknowledged their paresis when they were asked about the strength of their limbs. Their other deficits clearly had a greater impact. These patients had significantly milder paresis than those who denied their disorder even when asked directly about their limbs. CONCLUSIONS Patients who do not mention their paresis spontaneously but do so when questioned about it directly should not be diagnosed having "anosognosia." If this more conservative cut off criterion is applied to the data of the present as well as previous studies, a frequency of between 10% and 18% for anosognosia for hemiparesis is obtained in unselected samples of acute hemiparetic stroke patients. The incidence thus seems smaller than previously assumed.

Abstract
OBJECTIVE To investigate the impact of upper extremity deficit in subjects with tetraplegia. SETTING The United Kingdom and The Netherlands. STUDY DESIGN Survey among the members of the Dutch and UK Spinal Cord Injury (SCI) Associations. MAIN OUTCOME PARAMETER: Indication of expected improvement in quality of life (QOL) on a 5-point scale in relation to improvement in hand function and seven other SCI-related impairments. RESULTS In all, 565 subjects with tetraplegia returned the questionnaire (overall response of 42%). Results in the Dutch and the UK group were comparable. A total of 77% of the tetraplegics expected an important or very important improvement in QOL if their hand function improved. This is comparable to their expectations with regard to improvement in bladder and bowel function. All other items were scored lower. CONCLUSION This is the first study in which the impact of upper extremity impairment has been assessed in a large sample of tetraplegic subjects and compared to other SCI-related impairments that have a major impact on the life of subjects with SCI. The present study indicates a high impact as well as a high priority for improvement in hand function in tetraplegics.

Abstract
BACKGROUND Although familiar to every neurologist, postictal paresis (PP) has only rarely been analyzed systematically. OBJECTIVE To describe the frequency and duration of PP in patients undergoing video-EEG monitoring, the semiology characteristics of seizures preceding PP, and the pattern of associated symptoms and signs. METHODS The records of 513 consecutive patients who underwent prolonged video-EEG monitoring during presurgical epilepsy evaluation were reviewed for postictal motor deficit. Three hundred twenty-eight patients fulfilled the inclusion criteria. The videotapes of patients with PP were subsequently analyzed with a careful analysis of ictal motor phenomena at the side of the PP. RESULTS PP was found in 44 patients (13.4%). PP was always unilateral and always contralateral to the seizure focus and had a median duration of 173.5 seconds (range 11 seconds to 22 minutes). Of all seizures with PP, 77.8% were accompanied by evident and 9.7% by very slight ictal motor phenomena ipsilateral to the side of PP, whereas 9.7% of the seizures showed no motor signs (two seizures [2.8%] could not be evaluated for motor phenomena). The most common ictal lateralizing sign was unilateral clonic activity in 55.6% of all seizures. Concomitant dystonic posturing was found in 47.9% and ictal limb immobility in 24.6% of the seizures. PP was of longer duration if ictal clonic activity was present and after tonic-clonic seizures. CONCLUSIONS PP is relatively frequent (13.4%), is easy to detect, and has a high lateralizing value. The high incidences of dystonic posturing and of ictal limb immobility in our patients with PP may indicate that an active inhibitory process is involved in its pathogenesis.

Abstract
OBJECTIVE To determine whether ICU-acquired paresis (ICUAP) is an independent risk factor of prolonged weaning. DESIGN Second study of a prospective cohort of 95 patients who were enrolled in an incidence and risk factor study of ICUAP. SETTING Three medical and two surgical ICUs in four hospitals. PATIENTS AND PARTICIPANTS Ninety-five patients without pre-existing neuromuscular disease recovering from the acute phase of critical illness after > or =7 days of mechanical ventilation. INTERVENTIONS None. MEASUREMENTS AND RESULTS Duration of weaning from mechanical ventilation was defined as the duration of mechanical ventilation between awakening (day 1) and successful weaning. Muscle strength was evaluated at day 7 after awakening using the Medical Research Council (MRC) score. Patients with an MRC <48 were considered to have ICUAP. Among the 95 patients (mean age 62.0+/-15.3 years, SAPS 2 on admission 48.7+/-17.4) who regained satisfactory awakening after 7 or more days of mechanical ventilation, 67 (70.5%) were hospitalized in a medical ICU and 28 (29.5%) in a surgical ICU. Median duration (25th-75th percentiles) of weaning was longer in patients with ICUAP than in those without ICUAP: 6 days (1-22 days) vs 3 days (1-7 days); p=0.01; log-rank analysis. In multivariate analysis, the two independent predictors of prolonged weaning were ICUAP [hazard ratio (HR): 2.4; 95% confidence interval (CI): 1.4-4.2] and chronic obstructive pulmonary disease (HR: 2.7; 95% CI: 1.6-4.5) CONCLUSIONS ICU-acquired paresis is an independent predictor of prolonged weaning. Prevention of ICU-acquired neuromuscular abnormalities in patients recovering from severe acute illness should result in shorter weaning duration.

Abstract
BACKGROUND AND PURPOSE There is no consensus concerning the number of patients developing spasticity or the relationship between spasticity and disabilities after acute stroke. The aim of the present study was to describe the extent to which spasticity occurs and is associated with disabilities (motor impairments and activity limitations). METHODS Ninety-five patients with first-ever stroke were examined initially (mean, 5.4 days) and 3 months after stroke with the Modified Ashworth Scale for spasticity; self-reported muscle stiffness; tendon reflexes; Birgitta Lindmark motor performance; Nine Hole Peg Test for manual dexterity; Rivermead Mobility Index; Get-Up and Go test; and Barthel Index. RESULTS Of the 95 patients studied, 64 were hemiparetic, 18 were spastic, 6 reported muscle stiffness, and 18 had increased tendon reflexes 3 months after stroke. Patients who were nonspastic (n=77) had statistically significantly better motor and activity scores than spastic patients (n=18). However, the correlations between muscle tone and disability scores were low, and severe disabilities were seen in almost the same number of nonspastic as spastic patients. CONCLUSIONS Although spasticity seems to contribute to disabilities after stroke, spasticity was present in only 19% of the patients investigated 3 months after stroke. Severe disabilities were seen in almost the same number of nonspastic as spastic patients. These findings indicate that the focus on spasticity in stroke rehabilitation is out of step with its clinical importance. Careful and continual evaluation to establish the cause of the patient's disabilities is essential before a decision is made on the most proper rehabilitation approach.

Abstract
STUDY DESIGN A literature review was conducted to integrate and compile available reports on postoperative C5 palsy. OBJECTIVES To review the clinical features, possible pathogenesis, and procedures for treatment and prevention of postoperative C5 palsy as a complication of surgery for cervical compression myelopathy. SUMMARY OF BACKGROUND DATA Although postoperative C5 palsy develops in approximately 5% of patients after decompression surgery of the cervical spine, its pathogenesis and the options for prevention and treatment remain unidentified and many controversies exist. METHOD We reviewed and analyzed papers published from 1986 to 2002 regarding C5 palsy as a postoperative complication. Statistical comparisons were made when appropriate. RESULTS Postoperative C5 palsy is reported to occur in an average of 4.6% of patients after surgery for cervical compression myelopathy. No significant differences were noted between patients undergoing anterior decompression and fusion and laminoplasty, nor were distinctions apparent between unilateral hinge laminoplasty and French-door laminoplasty, or between cervical spondylotic myelopathy and ossification of the posterior longitudinal ligament. Two theories were put forth to account for the pathogenesis of C5 palsy: nerve root injury and segmental spinal cord disorder. Neither of these hypotheses has been consistently supported and evidence to refute each hypothesis can be found in the literature. Recently, surgeons have advocated foraminotomy combined with laminoplasty to prevent or treat C5 palsy, but further studies into the efficacy of this procedure are needed. Although patients with C5 palsy generally have a good prognosis for neurologic and functional recovery, those with severe paralysis require significantly longer recovery times when compared to more mild cases. CONCLUSION The incidence of postoperative C5 palsy has been reported at 4.6% after surgery for cervical compression myelopathy and this value has not varied with different surgical procedures or disease etiologies. The pathogenesis of postoperative C5 palsy remains unclear at the present time. Patients with postoperative C5 palsy generally have a good prognosis for functional recovery, but the severely paralyzed cases required significantly longer recovery times than the mild cases.

Abstract
OBJECT The use of radiosurgery for the treatment of cerebral arteriovenous malformations (AVMs) and other lesions demands an accurate understanding of the risk of radiation-related complications. Some commonly used formulas for predicting risk are based on extrapolation from small numbers of animal experiments, pilot human treatment series, and theoretical radiobiological considerations. The authors studied the incidence of complications after AVM radiosurgery in relation to dose, volume, and other factors in a large patient series. METHODS A retrospective review was conducted in 1329 patients with AVM treated by Dr. Raymond Kjellberg at the Harvard Cyclotron Laboratory (HCL) between 1965 and 1993. Dose and volume were obtained from HCL records, and information about patient follow up was derived from concurrent clinical records, questionnaires, and contact with referring physicians. Multivariate logistic regression with bootstrapped confidence intervals was used. Follow up was available in 1250 patients (94%); the median follow-up duration was 6.5 years. The median radiation dose was 10.5 Gy and the median treatment volume was 33.7 cm(3). Twenty-three percent of treated lesions were smaller than 10 cm(3). Fifty-one permanent radiation-related deficits occurred (4.1%). Of 1043 patients treated with a dose predicted by the Kjellberg isoeffective centile curve to have a less than 1% complication risk, 1.8% suffered radiation-related complications. Actual complication rates were 4.7% for 128 patients treated at Kjellberg risk centile doses of 1 to 1.8%, and 34% for 61 patients treated at risk centile doses of 2 to 2.5%. The fitted logistic model showed that complication risk was related to treatment dose and volume, thalamic or brainstem location, and patient age. CONCLUSIONS The Kjellberg isoeffective risk centile curve significantly underpredicted actual risks of permanent complications after proton beam radiosurgery for AVMs. Actual risks were best predicted using a model that accounted for treatment dose and volume, lesion location, and patient age.

Abstract
The risk of sustaining a stinger, CCN, or a more serious catastrophic injury to the cervical spine increases with increasing stenosis. The RR of a player sustaining a second stinger or CCN increases exponentially when compared with the risk of a player sustaining an initial stinger or CCN. Intravenous steroids have no role in the management of stingers or CCN. Players who remain symptomatic after a stinger, players with persistently abnormal diagnostic studies after a stinger, and any player who experiences a CCN should be excluded from further participation in contact sports.

Abstract
OBJECT Patients with arteriovenous malformations (AVMs) in a deep location and with deep venous drainage are thought to be at higher risk for hemorrhage than those with AVMs in other locations. Despite this, the natural history of AVMs of the basal ganglia and thalamus has not been well studied. METHODS The authors retrospectively evaluated a cohort of 96 patients with AVMs in the basal ganglia and thalamus with respect to the tendency of these lesions to hemorrhage between the time of detection and their eventual successful management. The 96 patients studied had a mean age of 22.7 years at diagnosis, and 51% were male. Intracranial hemorrhage (ICH) was the event leading to clinical detection in 69 patients (71.9%), and 85.5% of these patients were left with hemiparesis. After diagnosis, 25 patients bled a total of 49 times. The cumulative clinical follow up after detection but before surgical management was 500.2 patient-years. The risk of hemorrhage after detection of an AVM of the basal ganglia or thalamus was 9.8% per patient-year. CONCLUSIONS The rate of ICH in patients with AVMs of the basal ganglia or thalamus (9.8%/year) is much higher than the rate in patients with AVMs in other locations (2-4%/year). The risk of incurring a neurological deficit with each hemorrhagic event is high. Treatment of these patients at specialized centers is recommended to prevent neurological injury from a spontaneous ICH.

Abstract
BACKGROUND The main hereditary vascular conditions involving both retinal and cerebral vessels include cerebroretinal vasculopathy, HERNS (hereditary endotheliopathy with retinopathy, nephropathy, and stroke), and hereditary vascular retinopathy; all are linked to the same locus on chromosome 3p21. Hereditary retinal arteriolar tortuosity is a distinct, autosomal dominant condition characterized by retinal arteriolar tortuosity and recurrent retinal hemorrhages. This condition is known to affect only retinal vessels. METHODS Clinical and brain MRI investigations of eight members of a three-generation family and extensive biological and systemic vascular investigations within one affected family member were conducted. RESULTS Six of eight family members were clinically symptomatic; disorders included infantile hemiparesis (2), migraine with aura (3), and retinal hemorrhage (1). Five individuals had retinal arteriolar tortuosities. A diffuse leukoencephalopathy in association with dilated perivascular spaces was observed in six individuals. Two family members had silent, deep cerebral infarcts as demonstrated on MRI. Genetic linkage analysis strongly suggests that this disorder is not linked to the 3p21 hereditary vascular retinopathy/cerebroretinal vasculopathy/HERNS locus. CONCLUSIONS The authors describe a novel hereditary autosomal dominant condition affecting both retinal and cerebral vessels and characterized by infantile hemiparesis, migraine with aura, retinal hemorrhage, retinal arterial tortuosity, and leukoencephalopathy with dilatation of perivascular spaces and microbleeds on brain MRI. Investigation of additional families should help to map the gene and to better categorize the spectrum of hereditary cerebroretinal small vessel diseases.

Abstract
BACKGROUND The frequency at which unruptured cerebral aneurysms are detected has increased due to advances in low- or non-invasive diagnostic techniques. Despite the recent improvements in surgical and medical management of aneurysmal subarachnoid hemorrhages, however, the overall case-fatality rate of this disease is still high. To reduce it, the natural history of unruptured cerebral aneurysms should be better understood. METHODS The subjects consisted of 156 patients with unruptured cerebral aneurysms who had been admitted to the Department of Surgical Neurology, Jichi Medical School Hospital or Jichi Medical School Ohmiya Medical Center, Japan, between January 1989 and December 1998. All of the patients were classified according to the process by which aneurysms had been detected. The expected number of deaths was calculated by using age- and sex-specific mortality rates obtained from the vital statistics. A standardized mortality ratio and 95% confidence interval were calculated by using the expected and observed numbers of deaths. RESULTS The standardized mortality ratios differed among the groups according to the process of detecting aneurysms. The incidence rate of rupture of unruptured cerebral aneurysms was 1.3 per 100 person-years. The annual rupture rate of unruptured cerebral aneurysms was higher than previously reported. The survival rate of the group that underwent surgical treatment for unruptured cerebral aneurysms was higher than that of the untreated group. CONCLUSIONS The annual rupture rate of unruptured cerebral aneurysms may be higher than previously reported.

Abstract
CONTEXT Although electrophysiologic and histologic neuromuscular abnormalities are common in intensive care unit (ICU) patients, the clinical incidence of ICU-acquired neuromuscular disorders in patients recovering from severe illness remains unknown. OBJECTIVES To assess the clinical incidence, risk factors, and outcomes of ICU-acquired paresis (ICUAP) during recovery from critical illness in the ICU and to determine the electrophysiologic and histologic patterns in patients with ICUAP. DESIGN Prospective cohort study conducted from March 1999 to June 2000. SETTING Three medical and 2 surgical ICUs in 4 hospitals in France. PARTICIPANTS All consecutive ICU patients without preexisting neuromuscular disease who underwent mechanical ventilation for 7 or more days were screened daily for awakening. The first day a patient was considered awake was day 1. Patients with severe muscle weakness on day 7 were considered to have ICUAP. MAIN OUTCOME MEASURES Incidence and duration of ICUAP, risk factors for ICUAP, and comparative duration of mechanical ventilation between ICUAP and control patients. RESULTS Among the 95 patients who achieved satisfactory awakening, the incidence of ICUAP was 25.3% (95% confidence interval [CI], 16.9%-35.2%). All ICUAP patients had a sensorimotor axonopathy, and all patients who underwent a muscle biopsy had specific muscle involvement not related to nerve involvement. The median duration of ICUAP after day 1 was 21 days. Mean (SD) duration of mechanical ventilation after day 1 was significantly longer in patients with ICUAP compared with those without (18.2 [36.3] vs 7.6 [19.2] days; P =.03). Independent predictors of ICUAP were female sex (odds ratio [OR], 4.66; 95% CI, 1.19-18.30), the number of days with dysfunction of 2 or more organs (OR, 1.28; 95% CI, 1.11-1.49), duration of mechanical ventilation (OR, 1.10; 95% CI, 1.00-1.22), and administration of corticosteroids (OR, 14.90; 95% CI, 3.20-69.80) before day 1. CONCLUSIONS Identified using simple bedside clinical criteria, ICUAP was frequent during recovery from critical illness and was associated with a prolonged duration of mechanical ventilation. Our findings suggest an important role of corticosteroids in the development of ICUAP.

Abstract
BACKGROUND AND PURPOSE Although patterns of stroke occurrence and mortality have been well studied, few epidemiological data are available regarding the clinical characteristics of stroke events. METHODS We evaluated hospitalized stroke events reported in the Atherosclerosis Risk in Communities (ARIC) Study to describe the clinical characteristics of incident stroke. Confirmed stroke cases (n=474) were evaluated for stroke symptoms (headache, vertigo, gait disturbance, convulsions) and stroke signs (hemianopia, diplopia, speech deficits, paresis, paresthesia/sensory deficits) and their univariate associations with race, sex, and stroke subtype. RESULTS Over 9.2 years of follow-up, 402 (85%) ischemic and 72 (15%) hemorrhagic strokes occurred. Frequency of stroke symptoms (95% CIs) were as follows: headache (27.4%; 23.4% to 31.4%), gait disturbance (10.8%; 7.9% to 13.6%), convulsions (4.4%; 2.6% to 6.3%), and vertigo (2.1%; 0.8% to 3.4%). Speech deficits occurred in 24.0% (20.2% to 27.9%), hemianopia in 14.6% (11.4% to 17.7%), and diplopia in 5.5% (3.4% to 7.5%) of cases. Most cases involved paresis (81.6%; 78.1% to 85.1%), while fewer cases experienced sensory deficits (44.5%; 40.0% to 49.0%). Blacks were more likely than whites to experience paresis (85.4% versus 78.2%; P=0.044). Men were more likely than women to experience a gait disturbance (14.4% versus 6.7%; P=0.007). Persons with hemorrhagic strokes had a higher proportion of headaches (55.6% versus 22.4%; P=0.001) and convulsions (11.1% versus 3.2%; P=0.003) than those with ischemic events, while speech and sensory deficits were more common in ischemic strokes (26.1% versus 12.5%, P=0.013, and 49.0% versus 19.4%, P=0.001, respectively). CONCLUSIONS We present epidemiological data concerning the clinical characteristics of incident stroke in a population-based cohort. Although minor differences by race, sex, and stroke subtype were observed, data from additional follow-up are required to confirm observed variations.

Abstract
OBJECTIVE To examine the clinical characteristics of patients with brainstem strokes admitted to a rehabilitation unit. DESIGN Retrospective cohort. SETTING Inpatient rehabilitation unit. PARTICIPANTS Eighty-five consecutive admissions (56 men, 29 women; mean age, 61.9+/-14.4y; range, 18-85y) with radiologically confirmed focal evidence of specific lesions within the pons, midbrain, cerebellum, and medulla. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Various clinical characteristics, including stroke-related deficits and stroke risk factors, were identified and compared between brainstem subgroups. The incidence of complications, including pneumonia, deep vein thrombosis, and seizure disorder, was also reported. RESULTS Seventy (82%) of the strokes resulted from infarctions and 15 (18%) were caused by hemorrhages. The functional deficits of hemiparesis, ataxia, and diplopia were present in 41 (48%), 73 (86%), and 32 (38%) patients, respectively. Dysarthria was reported in 42 patients (49%) and dysphagia in 40 (47%). Pneumonia during hospitalization was a complication in 9 (11%) of the patients with brainstem stroke. The risk factors of diabetes and hypertension were present in 22 (26%) and 47 (55%) patients, respectively. Fourteen (17%) of these patients had suffered a previous stroke. CONCLUSIONS Rehabilitation patients experience a variety of functional impairments as a consequence of brainstem stroke. These include hemiparesis, dysarthria and dysphagia, diplopia, and ataxia. A significant number of patients had pneumonia as a complication. The characteristics and impairment profiles of patients within the subgroups were similar, with the exception of the incidence of ataxia and hemiparesis.

Abstract
BACKGROUND AND PURPOSE Severe motor deficits are the predominant cause of long-term disability in stroke patients. In particular, progressive hemiparesis in the initial stage after stroke onset is frequently devastating. Therefore, we attempted to define the population at risk with respect to the presumed pathogenesis. METHODS Among 941 stroke patients hospitalized during a 3-year period, 92 patients (41 men, 51 women; mean age, 68 years) had a severe motor deficit (<25 of 42 points on the 7 motor items of the European Stroke Scale) resulting from brain infarcts. Risk factors, neurological examinations, comprehensive diagnostic tests, and therapy were documented. The study population was separated into patients with (group A) and without (group B) progressive motor deficits. Progression was defined as a further decrease of at least 5 points on the initial European Stroke Scale motor score during the first 5 days after stroke onset. RESULTS Of the 92 patients, 23.9% had significant worsening of motor function with a decrease in the mean European Stroke Scale motor score from 20.3 to 12.9 points (P<0.01). Infarcts in group A patients were subcortical in 59.1%, whereas most infarcts were cortical in group B (61.4%, P<0.05). Progressive hemiparesis was also significantly associated with lacunar stroke (group A:, 59.1%; group B, 24.3%; P<0.01). With regard to risk factors, diagnostic studies, and neuroimaging, small-vessel disease was the predominant presumed cause of stroke in group A (63.6%, P<0.01), whereas infarcts in group B patients were frequently caused by embolism from cardiac or undetermined sources (61.4%, P<0.01). Prevalence of high-grade carotid stenosis was not significantly different between groups A and B; however, subtotal stenoses and complete internal carotid artery occlusions were found only among patients without progressive motor deficits. CONCLUSIONS Lacunar stroke caused by small-vessel disease is the major cause of progressive motor deficits, probably because of stepwise occlusion of the branches of small penetrating arteries.

Abstract
We report a typical case of bullous pemphigoid (BP) associated with a neurological disorder and study a possible link between neurological disorders and BP. An 84-year-old hemiplegic woman presented with unilateral BP on the hemiparetic side. BP was confirmed by histological and immunofluorescence data. The medical records of the previous 46 consecutive patients with BP were retrospectively analyzed (average age: 79; median age: 85). Thirty of the 46 patients with BP had neurological disorders. These disorders included dementia, epilepsy, multiple sclerosis, cerebral stroke, Parkinson's disease, gonadotropic adenoma, trembling, dyskinesia, lumbar spinal stenosis. In a control group of the 46 consecutive oldest patients (older than 71; average age: 82,5; median age: 80) with another skin disease referred during the previous two-year-period to our one-day-unit only, 13 patients had a neurological disorder. This study demonstrates that there is a high prevalence of neurological disorders in patients with BP (p = 0.0004). A prospective case control study with neurological examination and psychometrical evaluation is warranted to confirm these data. We speculate that neuroautoimmunity associated with the aging process or neurological disorders may be involved in pemphigoid development via an autoimmune response against dystonin which shares homology with bullous pemphigoid antigen 1. Bullous pemphigoid could be considered to be a marker of neurological disorder.

Abstract
BACKGROUND AND PURPOSE Purposes of this study are to describe different parenchymal changes seen after radiosurgery of cerebral arteriovenous malformations and the clinical symptoms which can be associated, and risk factors correlated with them. PATIENTS and method. From the whole population of 705 patients with a cerebral arteriovenous malformations treated by radiosurgery between 1984 and 1998, clinical from 615 patients and post radiosurgery MRI data from 367 patients were reviewed. Neurological deficit occurred in 5.37% of cases and was still persistant in 1.46% of cases. Delay of occurrence of deficits ranged from 6 to 83 months (mean: 27 months, median: 15 months). Parenchymal changes seen in MRI were classified in 4 grades: 1 without parenchymal changes, 2 hypersignal in sp T2, 3=2 with homogenous enhancement with gadolinium, 4 with hyposignal in spT1 and annular irregular enhancement. Several parameters (size, volume, angioarchitecture of the cerebral arteriovenous malformation, dosimetric parameters) were studied and correlations were searched by uni and multivariate analysis with occurrence and delay of occurrence of deficits or parenchymal changes. RESULTS In multivariate analysis, only size was significantly correlated with occurrence of parenchymal changes (p=0.0016); only size of the malformation was significantly correlated with delay of occurrence of parenchymal changes (p=0.0082); only grade 4 was correlated with occurrence of neurological deficit (p<0.00001). However, when only "a priori" parameters (known before radiosurgery) are introducted in logistic model, size taille (p=0.02) and hypoplasy of a sinus (p=0.0049) are significantly correlated with occurrence of neurological deficit. Only parenchymal changes grade 4 was significantly correlated with delay of occurrence of a neurological deficit (p<0.00001). However, when only a priori parameters (known before radiosurgery) are introducted in logistic model, only arterial steal (p=0.054) was significantly correlated with delay of occurrence of a neurological deficit. CONCLUSION Parenchymal changes are various in expression, signification and clinical symptoms associated with them. They must be known and recognized for better prevention and symptomatic treatment as well.

Abstract
OBJECTIVES The etiopathogenesis of acute unilateral peripheral vestibulopathy (APV) still remains a matter of debate; ischemic changes in the circulation of the labyrinth may play a role. We consequently looked for possible hemostasis alterations in a group of patients with APV of an unknown nature. METHODS We evaluated blood parameters known to be involved in circulation disorders, including total and HDL cholesterol, triglycerides, apolipoprotein A and B, lipoprotein(a), homocysteine, folate, prothrombin time, activated partial thromboplastin time, fibrinogen, D-dimer, antithrombin III, protein C, protein S, activated protein C resistance, and anticardiolipin IgG and IgM antibodies. A series of 23 patients affected with APV were consecutively referred to our department, in the acute phase, before treatment, and in the follow-up phase after 4 to 6 weeks of pharmacologic washout. The aforementioned blood parameters were also measured in a series of 15 patients with Menière's disease. RESULTS The patients with APV in the acute phase compared with the patients with Menière's disease in the acute phase exhibited increased plasma levels of fibrinogen (mean, 338.3 +/- 135.9 SD vs 271.3 +/- 69.8 SD mg/dL, P = 0.05), increased plasma levels of D-dimer (mean, 320 +/- 207.8 SD vs 226.7 +/- 138.7 SD NG/mL), enhanced plasma levels of lipoprotein(a) (41.4 +/- 38.6 SD vs 16 +/- 18.2 SD mg/dL, F = 5.67, P = 0.02), high leukocyte count (9.1 +/- 2.7 SD vs 6.5 +/- 1.3 SD x 10(3)/microL; F = 8.42, P < 0.006), and low serum folate concentration (5.3 +/- 1.8 SD vs 7.1 +/- 2.7 NG/mg; F = 4.34, P = 0.04). During follow-up the prothrombin time was prolonged (F = 4.34, P = 0.04) and leukocyte count decreased (F = 7.39, P < 0.019) in the APV patients, whereas fibrinogen, D-dimer, lipoprotein(a), and folate were unchanged. CONCLUSION Our results provide evidence suggesting an involvement of the hemostatic system in APV.

Abstract
BACKGROUND Leukoaraiosis (LA) may have specific clinical correlates in patients with stroke, but this is not well investigated, so that the significance of LA in patients with stroke remains unclear. METHODS In a study of 2289 patients with a first-ever acute ischemic stroke, LA was noted in 149 by the use of baseline computed tomography of the brain. These patients were compared with the non-LA group. Statistical tests, including Fisher exact test or a chi(2) test, were used to compare variables, and a multivariate approach using stepwise logistic regression was performed. RESULTS Patients with LA were significantly older (73.7 vs 62.7 years; P<. 001), and had a higher incidence of hypertension (72.5% vs 47.1%; P<. 001) and subcortical or lacunar infarction (40.3% vs 25.4% and 21.5% vs 8.0%, respectively; P<.001) on neuroimaging studies, compared with the non-LA group. The most common cause of stroke in the LA group was presumed to be small-artery disease associated with hypertension (46% vs 13.5% in the non-LA group). Age and hypertension were very strongly associated with LA (respective odds ratios [95% confidence intervals], 1.06 [1.04-1.08] and 2.33 [1.60-3. 39]). In addition to these risk factors, a close relationship was found between LA and nonsevere stenosis (<50%) of the internal carotid artery (odds ratio, 2.23 [95% confidence interval, 1.32-3. 76]), although the significance of this association remains speculative. The outcome at 1 month after stroke was similar in both groups. CONCLUSION Our results provide further evidence that LA is related primarily to small-vessel disease.

Abstract
OBJECTIVE To compare the risk of developing symptoms related to late effects of poliomyelitis between polio patients and persons of similar age and sex without history of poliomyelitis. MATERIAL AND METHODS The study comprised information on 148 patients with prior poliomyelitis and 115 persons with no history of poliomyelitis. Information was obtained by questionnaire and analyzed by multiple logistic regression method. RESULTS The risk of experiencing two or more symptoms was significantly higher among the polio patients than among the persons without history of poliomyelitis. The elevation in risk was less pronounced in the nonparalytic group (OR = 2.35; 95% CI = 0.92-5.97) than the group with permanent muscular weakness (OR = 8.84; 95% CI =4.32-18.09). CONCLUSIONS Although symptoms defined in the PPS are unspecific and may occur in the general population, the risk for developing such symptoms are higher among the polio victims. The difference in risk among nonparalytic and paralytic patients may depend on the extent of motor neuron damage in the acute stage.

Abstract
Seven hundred and nine patients fell ill in southern Germany (Baden-Württemberg) after infection with the tick-borne encephalitis (TBE) virus between 1994 and 1998. Detailed clinical and epidemiological data on TBE were available for 656 patients. A biphasic course of the disease occurred in 485 patients (74%). TBE presented as meningitis in 320 patients (49%), as meningoencephalitis in 270 (41%) and as meningoencephalomyelitis in 66 (10%). Eight of the patients (1.2%) died from TBE. Four hundred and forty-five patients (68%) had noticed a tick bite and the first symptoms occurred, on average, 7 days later. The most frequent neurological symptoms were impairment of consciousness (31%), ataxia (18%) and paresis of the extremities (15%) and cranial nerves (11%). Laboratory investigations revealed leucocytosis in the peripheral blood in 224 out of 392 patients (74%), elevation of the erythrocyte sedimentation rate in 223 out of 245 (91%), increased C-reactive protein in 127 out of 155 (82%), pleocytosis in the CSF of all patients tested, damage of the blood-CSF barrier in 255 out of 322 (79%), abnormalities in EEG in 165 out of 214 (77%) and abnormalities in MRI in 18 out of 102 (18%). In general, adolescents up to 14 years of age had a more favourable course of the disease than adults. Of 230 patients who were re-examined at a later time, 53 (23%) had moderate or severe sequelae. Patients with sequelae presented more frequently (P < 0.001) with impaired consciousness (Glasgow Coma Scale < 7), ataxia, pareses of the extremities or cranial nerves, a need for assisted ventilation, abnormal findings in MRI, pleocytosis > 300 cells/microl and impairment of the blood-CSF barrier (total protein > 600 mg/l). In view of the severity of the illness and the high frequency of sequelae, active immunization against TBE is recommended for all subjects living in and travelling to areas of risk. Prevention of TBE by post-exposure prophylaxis with hyperimmunoglobulins is less effective and therefore should be performed only when absolutely necessary.

Abstract
BACKGROUND AND PURPOSE Mirror movements (MM) are involuntary synchronous movements of one limb during voluntary unilateral movements of the opposite limb. We measured MM in stroke and control subjects and evaluated whether MM after stroke are related to motor function. METHODS Twenty-three patients and 16 control subjects were studied. A computerized dynamometer was used during two squeezing tasks to measure intended movements from the active hand as well as MM from the opposite hand. Motor deficits were measured with the arm motor component of the Fugl-Meyer scale. RESULTS During paretic hand squeezing, MM in the unaffected hand were detected in 70% (repetitive squeeze) to 78% (sustained squeeze) of stroke patients. For both tasks, this was significantly (P < 0.05) greater than the incidence of MM in the paretic hand or in either hand of control subjects (17% to 44%), except when compared with the incidence of MM in the dominant hand of control subjects (56%; P = 0.17). The incidence of MM in the paretic hand was not significantly different from that seen in either hand of control subjects. Patients with MM in the unaffected hand had significantly greater motor deficit than patients without MM. Patients with MM in the paretic hand had significantly better motor function than patients without MM. CONCLUSIONS Simultaneously recording motor performances of both hands provides precise information to characterize MM. MM in the unaffected hand and in the paretic hand are associated with different degrees of motor deficit after stroke. Evaluation of MM may be useful for studying mechanisms of stroke recovery.
