Abstract
BACKGROUND/AIM To investigate in variants of primary progressive aphasia (PPA) the association between current clinical and neuroimaging criteria and biochemical/genetic markers at the individual level. METHODS Thirty-two PPA patients were classified as non-fluent/agrammatic (nfvPPA), semantic (svPPA), or logopenic variant (lvPPA) or as unclassifiable (uPPA). In all patients, we evaluated the neuroimaging criteria (magnetic resonance imaging and/or single photon emission computed tomography/positron emission tomography) of each variant and studied serum progranulin levels, APOE genotype and Alzheimer's disease (AD)-cerebrospinal fluid (CSF) biomarkers. Cases with a first-degree family history of early-onset dementia were genetically tested. RESULTS Ten of 15 (66%) nfvPPA, 5/5 (100%) svPPA and 7/7 (100%) lvPPA patients showed at least one positive neuroimaging-supported diagnostic criterion. All lvPPA and 3/5 (60%) uPPA patients presented AD-CSF biomarkers, which were absent in nfvPPA and svPPA cases. Four (27%) nfvPPA patients had dementia-causing mutations: 2 carried a GRN mutation and 2 the C9ORF72 hexanucleotide expansion. CONCLUSIONS There was an excellent association between clinical criteria and neuroimaging-supported biomarkers in svPPA and lvPPA, as well as with AD-CSF biochemical markers in the lvPPA. Neuroimaging, biochemical and genetic findings in nfvPPA were heterogeneous. Incorporating biochemical/genetic markers into the PPA clinical diagnosis would allow clinicians to improve their predictions of PPA neuropathology, especially in nfvPPA and uPPA cases.

Abstract
INTRODUCTION Rivastigmine, a treatment for mild to moderate Alzheimer disease (AD), is the first cholinesterase inhibitor to be available in the transdermal format. We aim to describe user experience and satisfaction with the rivastigmine patch, as well as any clinical changes perceived in patients. METHODS Observational, cross-sectional, multicentre study with 239 investigators and 1851 informal caregivers of patients with mild to moderate AD. Patients were treated with transdermal rivastigmine patches for ≥ 6 months and had previously received high doses of oral rivastigmine. RESULTS Mean caregiver age was 59.8±14.4 years and 70.9% were women. They spent 10.0±7.1hours per day providing care and 79.8% lived with the patient. Patch instructions were described as easy to follow by 97.1% of the caregivers and 92.1% of them rated patch application as easy or very easy. The most commonly cited disadvantage was adhesion problems (26.8%). Discontinuation of treatment was due to cutaneous reactions in most cases. Overall, 76.5% of the caregivers were satisfied or very satisfied with transdermal treatment and 77.4% considered that its interference with daily activities was minimal or null. The patch was preferred to oral treatment by 94.3% of caregivers. Clinical Global Impression of Change ratings improved according to 61.3% of the caregivers and 53% of the investigators. Few caregivers reported medication forgetfulness. CONCLUSIONS Most caregivers of patients with mild to moderate AD preferred the transdermal format of rivastigmine to the oral format. Caregivers also reported overall satisfaction, ease of use, and reduced impact on daily activities for transdermal rivastigmine format, in addition to patient improvement compared to their condition under the previous treatment.

Abstract
INTRODUCTION Neurosarcoidosis accounts for approximately 5% of cases of sarcoidosis. OBJECTIVE To determine the frequency of Neurosarcoidosis in our setting and analyze the clinical-radiological findings and evolution of 30 patients consecutively diagnosed. METHODS The medical records of patients with a diagnosis of Neurosarcoidosis were reviewed, and data regarding the clinical features, ancillary tests performed, treatment, and outcome were recorded. We revised the literature to summarize and discuss the previous clinical series of Neurosarcoidosis. RESULTS It accounted for 6.7% of all cases of sarcoidosis. Seven patients had definite diagnosis and 23 had probable diagnosis. The mean age at onset of Neurosarcoidosis was 48.3 years and 66.7% of patients were women. Neurologic clinical features were the first manifestation of Neurosarcoidosis in 70% of cases. Cranial neuropathy was present in 17 patients and 14 of them had facial palsy. The central nervous system was affected in 10 patients and the peripheral nervous system in 5. Chest disease, the most common extraneurologic manifestation, was present in 20 patients. All patients were treated with corticosteroids, and all those with central nervous system involvement had poor outcome. CONCLUSION Neurosarcoidosis requires a high degree of suspicion to establish the diagnosis. Central nervous system involvement is associated with a poor prognosis.

Abstract
INTRODUCTION Wernicke's encephalopathy (WE) is an underdiagnosed condition, usually associated with alcoholism, and has a worse prognosis if there is a delay in diagnosis. A series of 8 non-alcoholic patients with WE is presented and an assessment is made on whether a delay in diagnosis leads to a worse prognosis. PATIENTS AND METHODS The clinical records of patients admitted to 2 university hospitals between 2004 and 2009 with the diagnosis of WE, excluding those with a history of alcoholism, were retrospectively reviewed. RESULTS The study included 4 men and 4 women aged 35-82 of whom 7 had a history of gastrointestinal pathology, and persistent vomiting was the precipitating factor in 7. Encephalopathy was the most frequent onset symptom (4). The classical triad was present in seven patients. Thiamine levels were low in 3/6 and normal in 3/6 cases. MRI was abnormal in seven patients, with high signal intensity in the diencephalon and mammillary bodies (7), periaqueductal grey matter (6), cortex (3) and cerebellum (1). Seven improved with thiamine. Sequelae were mild in 6, and severe in 2 after 6-12 months of follow-up. All patients with a diagnostic delay less than 18 days had mild sequelae. CONCLUSIONS Non-alcoholic WE frequently occurs after gastrointestinal disturbances that could result in lower thiamine absorption. Whereas thiamine levels can be normal in many cases, in almost all cases the MRI shows signal alterations in typical locations. A delay in the diagnosis, and therefore, in treatment leads to a worse prognosis.

Abstract
OBJECTIVES To estimate dementia prevalence in Spain. MATERIALS AND METHODS Nine probabilistic and geographically defined samples participated. A screening design based on the MMSE was implemented. Positively screened individuals underwent clinical evaluation. The total number of cases in Spain was estimated. Prevalence was confronted to that of other European countries. RESULTS Five hundred and forty-six persons aged ≥75 participated, 49 had dementia (35 with Alzheimer's disease [AD], 10 with vascular dementia [VD], 4 other; 25 first diagnosed in the study). Age- and sex-adjusted prevalence and estimated nationwide cases were 7.5% (95% CI 5.4-9.7), 5.6 (95% CI 3.7-7.5) and 1.4 (95% CI 0.5-2.3), and 290,000 (95% CI 208,000-372,000), 214,000 (95% CI 141,000-288,000) and 54,000 (95% CI 20,000-88,000) for dementia, AD and VD, respectively. CONCLUSIONS Dementia prevalence in Spain is comparable to other European populations, while a high number of undiagnosed cases live in the community. The potential impact of Mediterranean diet, hypertension control and decreasing vascular risk factors is discussed.

Abstract
INTRODUCTION Frontotemporal lobar degeneration (FTLD) is considered to be the second cause of presenile dementia. In spite of the great interest it has generated over the last few years, few studies have been published in our country. METHODS A descriptive retrospective study of 42 patients with FTLD evaluated in our unit during the period 1996-2006 was performed. RESULTS Thirty one patients presented with frontal variant FTLD (FTD), eigth with non-fluent progressive aphasia and three with semantic dementia. Mean age at onset was 56 years, diagnostic delay 3.5 years and mean survival 6.8 years. 35% had a family history suggestive of dementia. In patients with FTD the clinical expression was a combination of behavioral and personality disorders together with language impairment. Magnetic resonance imaging showed frontal and/or temporal atrophy in 62% of cases and SPECT showed frontal and/or temporal hypoperfusion in 75%. The P301L tau mutation was detected in four patients (two of them siblings) and the A303AfsX57 progranulin mutation in one. Necropsy was performed in five patients, revealing FTLD with ubiquitininmunoreactive inclusions (FTLD-U) and motor neuron disease in two cases, FTLD-U with <<cat's-eye>> shaped intranuclear inclusions in the case with the progranulin mutation and FTLD tauopathy with predominance of 4R tau in the remaining two, both with the P301L mutation. CONCLUSIONS Our results are similar to those of the great European series. FTLD must be suspected in presenile patients with prominent behavioral and/or language disorders. Neuroimaging supports the diagnosis in the majority of cases. The huge sociofamiliar impact of FTLD, presenile onset, high frequency of familial history of dementia and possibility of genetic study and counseling highlight its clinical relevance.

Abstract
BACKGROUND Studies on dementia subtypes show a wide variation in the prevalence of Alzheimer's disease (AD) and vascular dementia (VD) worldwide. However, studies reporting on Lewy body dementia (LBD) and frontotemporal dementia (FTD) are sparse. AIMS To describe the prevalence of dementia and subtypes. METHOD A 34% sample of 5,150 subjects aged 70 years and over in El Prat de Llobregat (Barcelona) were screened by the Mini-Mental State Examination. When scoring <24, participants were assessed to establish a diagnosis. RESULTS There were 165 subjects diagnosed with dementia (prevalence of 9.4%). Subtypes of dementia were: AD 69.1%, VD 12.7%, LBD 9.1%, FTD 3% and secondary dementia 1.8%. Prevalences were: AD 6.5%, VD 1.2%, LBD 0.9% and FTD 0.3%. CONCLUSIONS AD and VD were the most common type of dementia. Prevalence of dementia, AD and FTD were similar to those reported, while prevalence of VD and LBD were lower.

Abstract
Recurrent deletions of the 17q21.31 region encompassing the microtubule-associated protein tau (MAPT) gene have recently been described in patients with mental retardation. This region is flanked by segmental duplications that make it prone to inversions, deletions and duplications. Since gain-of-function mutations of the MAPT gene cause frontotemporal lobar degeneration (FTLD) characterized by deposition of tau protein, we hypothesize that MAPT duplication affecting gene dosage could also lead to disease. Gene dosage alterations have already been found to be involved in the etiology of neurodegenerative disorders caused by protein or peptide accumulation, such as Alzheimer's and Parkinson's diseases. To determine whether MAPT gene copy number variation is involved in FTLD, 70 patients with clinical diagnosis of FTLD and no MAPT mutation (including 12 patients with pathologically proven tau-positive FTLD) were screened by using multiplex ligation probe amplification (MLPA) with specific oligonucleotide probes. No copy number variation in the MAPT gene was observed in cases. Although our study was limited by the relatively small number of patients, it does not support the theory that chromosomal rearrangements in this region are a cause of FTLD.

Abstract
We describe a new mutation in the PGRN gene (A303AfsX57) associated with late-onset frontotemporal dementia and with "cat's eye" shaped intranuclear and cytoplasmatic ubiquitin immunoreactive inclusions in the neuropathological exam. The A303AfsX57 mutation is consistent with a nucleotide deletion in exon 8 (c908delC). This deletion causes a frameshift at codon 303 that introduces a premature termination codon (A303AfsX57).

Abstract
INTRODUCTION The aim of this study was to re-analyze door-to-door studies on neurological diseases among the elderly, in which vascular risk factors (VRF) were studied, describing methodological characteristics and prevalence of VRF. METHODS The surveys were identified in two phases. They were aimed at ascertaining prevalence of stroke, dementias or Parkinsonisms and, at the time of individual screening, had collected data on at least three of the following VRF: arterial hypertension (AHT), smoking habit, diabetes mellitus and hypercholesterolemia. A questionnaire was drawn up to collect the data reported in each study, and a database was constructed. VRF prevalences were quantified and analyzed using logistic regression. RESULTS The total of the re-analyzed population was 12,510 persons aged 70 years and over, residents in seven geographic areas during the period 1994-2002. Information available on VRF was essentially self-reported. The prevalence of self-reported AHT was 25.7 % in men and 44.2 % in women, and that of measured AHT was 61 % and 71.9 %, respectively. Populations with arterial pressure obtained by direct measurement registered 138 higher risks (OR: 1.74; 95 % CI: 1.51-2.01, and OR: 1.48; 95% CI: 1.33-1.64). Reported prevalence of diabetes, hypercholesterolemia and smoking habit were 14.3 %, 23.3% and 8.5 %, respectively. CONCLUSIONS There was a high prevalence of VRF among the Spanish elderly population. However, its relationship with dementia, Parkinsonisms and cerebrovascular disease could not be studied due to the poor quality of the VRF data. The differences between measured and self-reported arterial pressure suggest the existence of undetected AHT and wide scope for prevention.

Abstract
Antidisialosyl antibodies have been previously associated to chronic and acute ataxic neuropathies. We studied the presence of these antibodies in nine patients with acute self-limiting ataxic neuropathy (ASLAN) using ELISA and TLC immunodetection. One patient showed serum IgG immunoreactivity against gangliosides GD3 and GQ1b. The patient's IgG was able to bind to the nodes of Ranvier on frozen human dorsal root. Our studies confirmed that antidisialosyl reactivity is associated to ataxic neuropathy and its specific binding to the dorsal root could explain the predominant sensory involvement. Nevertheless, the low incidence of this reactivity indicates that a different pathogenic mechanism should be involved in most ASLAN patients.

Abstract
INTRODUCTION AND OBJECTIVE The so-called neurological paraneoplastic syndromes (NPNS) are a group of diseases of the central nervous system of unknown etiology which are seen almost exclusively in patients with cancer. We review the main NPNS paying particular attention to those with ophthalmological and otological features. DEVELOPMENT Certain neuro-ophthalmological findings may constitute, at least partly, some paraneoplastic syndromes. There are alterations of vision in paraneoplastic retinopathy and in optic neuritis of paraneoplastic origin. The latter, unlike the retinopathy, usually coexists with involvement of other structures of the nervous system. Oculomotor function is affected in the opsoclonus-myoclonus syndrome. Diplopia and/or ophthalmoplegia may be a predominant or initial symptom, in patients with paraneoplastic neurological degeneration or brainstem encephalitis. In the Lambert-Eaton syndrome and in paraneoplastic encephalomyelitis, may have blurred vision and alterations of the pupil. Cases of paraneoplastic uveitis have also been described. Paraneoplastic otological involvement is less frequent. Patients with sensorineural deafness in the context of a paraneoplastic encephalomyelitis have been reported. In the NPNS vertigo is caused by cerebellar or brainstem lesions and not by lesions of peripheral organs. When nystagmus occurs in a NPNS it may be of various types and is due to involvement of structures in the brain stem or cerebellum. CONCLUSIONS The diagnosis of NPNS in patients with no known cancer is important because it may lead to the detection of an occult cancer which is localized or scarcely extended, and therefore is still potentially treatable. Oto-neuro-ophthalmological manifestations may be the first or only symptom of presentation of a paraneoplastic neurological clinical picture.

Abstract
The outcome of 34 women with anti-Yo-associated paraneoplastic cerebellar degeneration was reviewed. Three patients had not developed cancer after more than 4 years of follow-up. The only independent predictor for survival was the type of associated tumor (risk ratio, 1.79; 95% CI, 1.02 to 3.12). Median survival was 100 months for patients with breast cancer and 22 for those with gynecologic cancer. Although paraneoplastic cerebellar degeneration leads to the diagnosis of cancer in 63% of the patients, cancer progression was the cause of death in 52%.

Abstract
OBJECTIVE To evaluate 1) the effect of the tumor treatment on the clinical course of paraneoplastic encephalomyelitis (PEM) with anti-Hu antibodies, 2) the impact of immunotherapy on the tumor evolution, and 3) the outcome of the small cell lung cancer (SCLC) of PEM patients compared with that of patients without PEM. METHODS The authors retrospectively analyzed 51 PEM patients (42 with SCLC, 9 with other tumors) who received antineoplastic treatment with (25 patients) or without (26) concomitant immunotherapy. Tumor response was assessed at the end of the antineoplastic treatment. Progression of PEM was defined as a change of at least 1 point in the Rankin scale measured at the onset and at the end of the tumor treatment. To evaluate the outcome of SCLC, 27 PEM patients with SCLC were matched one-to-one with SCLC patients without PEM for age, performance status, tumor stage, and type of antineoplastic treatment. RESULTS Thirty-six (70%) patients were neurologically stable at the end of the tumor treatment. In a logistic regression analysis, tumor complete response was the only predictor of PEM stabilization (OR 7.07; 95% CI 1.68 to 29.76; p = 0.006). Immunotherapy did not modify the outcome of the tumor and PEM. Median survival was similar in SCLC patients with and without PEM, but the probability of survival at 30 months was higher in PEM patients with SCLC (OR 5.26; 95% CI 1.0004 to 27.6902; p = 0.03). CONCLUSIONS Complete response of the tumor seems to have a favorable influence on the course of paraneoplastic encephalomyelitis (PEM). Concomitant immunotherapy does not adversely affect the tumor outcome. The small cell lung cancer of PEM patients may have a slightly better evolution than that of patients without PEM.

Abstract
PURPOSE Anti-Hu antibodies (HuAb) recognize antigens expressed by neurons and small-cell lung cancer (SCLC). High titers of HuAb were initially reported in serum from patients with paraneoplastic encephalomyelitis/sensory neuropathy (PEM/SN) and SCLC. Preliminary studies have indicated that some SCLC patients without PEM/SN harbor low titer of HuAb in their serum, and that the SCLC of these patients may grow more indolently. Based on these observations, we conducted a multicenter prospective study of SCLC patients without PEM/SN to determine the incidence and prognostic implications of HuAb. METHODS Serum samples were collected at diagnosis of SCLC in 196 patients without PEM/SN. HuAb were determined by immunoblot of purified recombinant HuD antigen. RESULTS HuAb were detected in 32 (16%) of the 196 patients. Of the 170 patients who received treatment for the tumor, 27 (16%) were HuAb positive. HuAb was associated with limited disease stage (59.3% v 38.6%; P = .047), complete response to therapy (55.6% v 19.6%; P < .001), and longer survival (14.9 v 10.2 months; P = .018). In a logistic regression analysis, HuAb status was an independent predictor of complete response induction. The probability of achieving a complete response was more than five times higher in HuAb-positive than in HuAb-negative patients (odds ratio, 5.4; 95% confidence interval, 1.71 to 16.89; P = .004). Cox multivariate analysis indicated that HuAb status was not independently associated with survival. CONCLUSION The presence of HuAb at diagnosis of SCLC is a strong and independent predictor of complete response to treatment. This feature accounts for the association between HuAb and longer survival.

Abstract
Paraneoplastic limbic encephalitis (LE) is considered a particular manifestation of paraneoplastic encephalomyelitis (PEM), a remote effect of cancer almost always associated with anti-neuronal antibodies (anti-Hu; also called ANNA 1) and small cell lung carcinoma (SCLC). In order to define the frequency of anti-Hu antibodies in LE with SCLC and to analyse possible clinical differences between patients with and without anti-Hu antibodies, the charts of 16 patients with LE and SCLC were reviewed. Eight patients (50%) had anti-Hu antibodies (anti-Hu+) whereas eight patients (50%) had no detectable anti-neuronal antibodies (anti-Hu-). The clinical and laboratory features of LE and time to diagnosis of SCLC were similar in the anti-Hu+ and anti-Hu- groups. Involvement of other areas of the nervous system compatible with the diagnosis of PEM was observed in seven (87.5%) patients of the anti-Hu+ group but in only one (12.5%) of the anti-Hu- group (P = 0.012). Five patients, including four of the anti-Hu- group, had a partial improvement of the LE after treatment of the SCLC. Another anti-Hu- patient improved spontaneously. Six patients of the anti-Hu+ group died from the neurological disorder, whereas in the anti-Hu- group the cause of death was progression of the SCLC in the three patients who died. The results of this study indicate that the absence of anti-Hu antibodies does not rule out the presence of an underlying SCLC in patients with a clinical diagnosis of LE. Patients with LE and SCLC who are without anti-Hu antibodies are less likely to develop PEM and seem to improve more often after treatment of the cancer than those who present anti-Hu antibodies.

Abstract
In patients with HIV infection, disease due to CMV depends on reactivation of the virus. Such reactivation usually occurs at an advanced stage of the disease, when there is severe immunodepression and the CD4+ leukocyte count is < 100/ml. CMV infection is seen clinically as three syndromes: 1) encephalitis with or without associated meningitis and/or ventriculitis. 2) polyradiculomyelitis affecting the lumbosacral roots, and 3) multifocal senso-motor neuropathy. Diagnosis depends on showing the virus to be present in the CSF, by detecting the early CMV antigen or by conventional culture. There are marked differences between encephalitis, polyradiculomyelitis and multifocal neuropathy in the rentability of viral culture. Whilst in encephalitis CMV culture is negative in most patients, in polyradiculomyelitis the sensitivity of viral culture may be 50-60% and in multifocal neuropathy 15%. The treatment indicated is with ganciclovir or foscarnet. Results depend on the type of neurological disease, degree of involvement when treatment is started and an history of extracerebral CMV infection previously treated with these drugs.

Abstract
OBJECTIVE To evaluate the effect of intravenous high dose human immunoglobulin (IVIg) therapy on the clinical course and autoantibody titres of patients with neurological paraneoplastic syndromes. METHODS Twenty two patients with paraneoplastic encephalomyelitis and sensory neuronopathy syndrome associated with anti-Hu antibodies (18) or paraneoplastic cerebellar degeneration (PCD) with anti-Yo antibodies (four), were treated with 1-26 (mean 5.8) cycles of IVIg. The Rankin scale was used to evaluate the response. RESULTS The only serious toxicity was one case of haemolytic anaemia. Twenty one patients were evaluable for therapeutic response. One patient, with subacute sensory neuronopathy (SSN), improved for at least 15 months, 10 remained stable (eight with anti-Hu and two with anti-Yo antibodies), and 10 deteriorated (eight with anti-Hu and two with anti-Yo antibodies). In seven of the 10 patients who stabilised, the syndrome had already made a plateau when the treatment was started but three patients (one with anti-Hu and two with anti-Yo antibodies) who had still been progressing stabilised for six, eight, and more than 48 months, including one patient with SSN who achieved stabilisation when the neurological dysfunction was only moderate (Rankin scale = 3). Another patient with SSN and initial stable response worsened when IVIg was reduced and improved when it was increased. No significant predictive factors of outcome could be identified but improvement or stabilisation was more frequent in patients with isolated involvement of the peripheral nervous system (62%) than in patients with evidence of CNS damage (37%) at the onset of treatment. Stabilisation in patients with CNS involvement was only achieved when the neurological dysfunction was already severe (Rankin scale > 3). The titres of autoantibodies did not change significantly. CONCLUSION Treatment with IVIg at the doses given in the present protocol was not effective in paraneoplastic CNS syndromes associated with antineuronal antibodies. The role of this regime in the treatment of SSN should be further evaluated.

Abstract
Paraneoplastic sensory neuropathy (PSN) usually runs a subacute progressive course, leaving the patient with severe sensory dysfunction in weeks to months. We describe five patients with PSN, high titers of anti-Hu antibodies (type 1 antineuronal nuclear autoantibodies), and an indolent clinical course. The patients had a median age of 55 years (range, 41 to 72). Four had small-cell (3) or undifferentiated large-cell (1) lung cancer. Patients presented with mild, asymmetric sensory symptoms; in two, the neuropathy was predominant in the arms. Two patients also had a visceral neuropathy causing gastrointestinal dysfunction. The PSN was stable or progressed very slowly without treatment for a median of 18 months (range, 5 to 32) and remained so after treatment with immunoglobulins (1 patient), chemotherapy (3), or both therapies (1). All patients were ambulatory, leading an independent life up until the time of the last visit or until death from the tumor (2 patients). The median follow-up was 36 months (range, 22 to 52). A paraneoplastic origin should be considered in patients with mild, very slowly progressive sensory neuropathies.

Abstract
Primary meningeal lymphomas are an infrequent disease representing 1% of the primary cerebral lymphomas. Progressive paraparesia constitutes the most frequent presentation with progressive infiltration of the cranial nerves being an usual initial manifestation. The case of a primary meningeal lymphoma is presented in a 76 years old patient in whom the form of presentation involved progressive infiltration of cranial nerves. Repeated lumbar punctions demonstrated infiltration of cranial nerves. Repeated lumbar punctions demonstrated inflammatory changes with high protein levels and low sugar levels in cerebrospinal fluid and pleocytosis. No malignant cells were observed upon cytologic study of the LCR. The importance of the determination of tumor markers in LCR and the use of MR with gadolinium in the early diagnosis of this entity is commented upon.

Abstract
BACKGROUND Twenty-four patients with neurologic involvement and anti-Hu antibodies were studied with the aim of defining the type of tumor associated, evaluating whether the clinico-pathologic picture agreed with the concept of paraneoplastic encephalomyelitis (PEM) and evaluating the treatments used. METHODS The study was retrospective with the clinical histories being reviewed to define the neurologic syndromes, their evolution and response to the different treatments, time of appearance and type of tumor as well as the neuropathologic changes in the patients undergoing autopsy. RESULTS In 18 patients a neoplasm was diagnosed as small cell pulmonary carcinoma (SCPC) in 89% of the cases. The neurologic picture preceded the tumor by an average of five months. The clinical pictures included: sensitive neuropathy (20 patients), cerebellous and truncus encephalicus involvement (8 patients), motor neuropathy (6 patients), cortical involvement (5 patients) and neurovegetative dysfunction (4 patients). In 55% of the patients more than one area was altered. Post mortem studies carried out on 5 patients demonstrated inflammatory infiltrates and neuronal loss in multiple areas of the nervous system. None of the patients improved with treatment. The 9 patients who only received immunodepressants evolved in a way similar to those who were not treated. In 7 of the 11 patients who received antitumoral therapy, the neurologic syndrome stabilized for at least 6 months. CONCLUSIONS The clinicopathological picture and the associated tumor seen in patients with anti-Hu antibodies are identical to those seen in PEM. Antitumoral treatment seems to be more effective than immunodepressant treatment.

Abstract
According to the diagnostic criteria currently in use, the so-called "unilateral" forms of the moyamoya disease, or rather those in which the disorders of the disease itself--such as occlusion of the internal supraclinoid carotid artery or its terminal branches and development of abnormal collateral circulation in the region of the basal ganglia--are only found in one hemisphere and should be considered as "probable" forms of the disease with a much lower incidence than the bilateral or "defined" forms of the same. One patient with a primary intraventricular hemorrhage (PIVH) in whom an occlusion of the right internal carotid artery was angiographically demonstrated and in whom collateral type moyamoya circulation was found as was the presence of an aneurysm in the right coroid territory is presented. The association of PIVH, unilateral moyamoya disease and aneurysm is infrequent in the literature, with the origin of the bleeding, in some cases, having been attributed to rupture of the aneurysm. Since angiographic control was not available in the patient presented it cannot be excluded that the aneurysm was really a pseudoaneurysm therefore being a consequence, rather than a cause, of the arterial rupture. Thus one of the other mechanisms proposed must be invoked to explain the pathogenesis of the PIVH: rupture of a perforating artery or of a microaneurysm located in the subependimary periventricular region. The treatment recommended for these case of PIVH associated to aneurysm is chirurgical if persistence is demonstrated in successive arteriographies.

Abstract
The case of a HIV positive patient with lumbosacral polyradiculomyelitis by cytomegalovirus (PLS-CMV) is presented. The patient was a homosexual male receiving maintainance treatment with foscarnet for previous corioretinitis by CMV who consulted for paraparesia and sphincter disorders of a 3 week evolution. Neutrophilic pleocytosis and high levels of glucose and proteins were observed on LCR and CMV isolated discarding other entities. The LCR normalized upon treatment with gancyclovir although serious residual paraparesia persisted. PLS-CMV is an infrequent entity of typical clinic and liquoral characteristics. Recognition of the same is important since favorable response depends on early anti-CMV treatment.

Abstract
We retrospectively evaluated the effect of plasmapheresis (PE) in seven patients with paraneoplastic encephalomyelitis (PEM), small-cell lung carcinoma, and anti-Hu antibodies, and four patients with paraneoplastic cerebellar degeneration (PCD), ovarian or breast cancer, and anti-Yo antibodies. In addition to PE, patients received prednisone (nine), cyclophosphamide (eight), or treatment of the tumor (five). All but one patient were severely disabled by the time PE began. The clinical outcome was compared with that of five patients (PEM, four; PCD, one) who only had treatment of the tumor. Only one of these five patients had a severe neurologic deficit at the onset of the antineoplastic treatment. No patient improved. Two patients treated with PE and antineoplastic therapy and three who only received treatment of the tumor remained stable for at least 6 months. Four of the five patients with a stable course started the treatment when the neurologic deficit was not severe. We conclude that the efficacy of PE with other immunosuppressive therapies in the stabilization of the neurologic deficit is uncertain.

Abstract
A series of eight patients with cerebral tuberculoma seen between 1980 and 1990 is reported. Headache was the leading clinical finding, followed by focal neurological findings and seizures. Papilledema was the most uniform examination finding associated with intracranial hypertension. Five patients had another localization of tuberculosis: three had tuberculous meningitis, one had tuberculous pericarditis and only one had associated active pulmonary involvement. Cerebrospinal fluid was investigated in seven patients. In three patients data of tuberculous meningitis were found, with positive culture in Löwenstein medium. Two patients had the acquired immunodeficiency syndrome. All patients received medical treatment with good response, except in one who developed paradoxical expansion of the lesions after two months of therapy.

Abstract
This study reports two female patients with progressive muscular rigidity beginning to the paravertebral and pelvic muscles associated with muscular spasms. The electromyography showed continuous muscular activity originated at the central nervous system. In both cases we observed the complete rigid man syndrome. Complementary explorations including thyroid hormonal study, ceruloplasmin, electroencephalogram, cranial computerized tomography, and magnetic resonance were normal. Auditive evoked potentials evidenced a prolongation of the interlatency III-V, suggesting pathologic involvement of the encephalic trunk. In one patient an artificial reservoir was inserted to instill baclofen into the meningeal space and produced a clinical improvement. The actual status of this rare illness is reviewed.

Abstract
Malignant external otitis (MEO) is a disease of the external auditive channel (EAC) due to Pseudomonas aeruginosa which usually involves individuals with diabetes mellitus. It may result in the invasion of the cranial base with cranial neuropathy and a high mortality rate despite therapy. We report the clinical features, diagnostic procedures, evolution and therapy of 8 patients with MEO, seven of which had cranial neuropathy. All patients have diabetes except one who had acquired immunodeficiency syndrome. All had otalgia, otorrhea and headache lasting for several months. Six patients had homolateral (as related to the MEO) facial palsy. One patient with bilateral MEO developed bilateral facial palsy and lesion of the cranial nerves VI (unilaterally) and IX through XII (bilaterally). In all patients P. aeruginosa was cultured from the EAC exudate scintigraphy with 99Tc showed uptake at medium ear and mastoid level in all 8 patients, suggesting a possible osteomyelitis. Scintigraphy with 67Ga was positive in the 6 cases where it was carried out, showing uptake in the soft tissues of the cranial base. Computed tomography was carried out in 6 patients, and it was useful to define the anatomical extent of the disease. The patients received different therapeutic schedules, particularly the combination of a betalactamic and aminoglucoside antibiotics. Follow up was characterized by common recurrences, and one patient died. The importance of early diagnosis and treatment to prevent the extension and recurrence of MEO are discussed. Cranial neuropathy is considered as a poor prognostic finding.
