Abstract
Peripheral neuropathy is a common problem in patients with Parkinson's disease. Peripheral neuropathy's prevalence in Parkinson's disease varies between 4.8-55%, compared with 9% in the general population. It remains unclear whether peripheral neuropathy leads to decreased motor performance in Parkinson's disease, resulting in impaired mobility and increased balance deficits. We aimed to determine the prevalence and type of peripheral neuropathy in Parkinson's disease patients and evaluate its functional impact on gait and balance. A cohort of consecutive Parkinson's disease patients assessed by movement disorders specialists based on the UK Brain Bank criteria underwent clinical, neurophysiological (nerve conduction studies and quantitative sensory testing) and neuropathological (intraepidermal nerve fibre density in skin biopsy punches) evaluation to characterize the peripheral neuropathy type and aetiology using a cross-sectional design. Gait and balance were characterized using wearable health-technology in OFF and ON medication states, and the main parameters were extracted using validated algorithms. A total of 99 Parkinson's disease participants with a mean age of 67.2 (±10) years and mean disease duration of 6.5 (±5) years were assessed. Based on a comprehensive clinical, neurophysiological and neuropathological evaluation, we found that 40.4% of Parkinson's disease patients presented peripheral neuropathy, with a predominance of small fibre neuropathy (70% of the group). In the OFF state, the presence of peripheral neuropathy was significantly associated with shorter stride length (P = 0.029), slower gait speed (P = 0.005) and smaller toe-off angles (P = 0.002) during straight walking; significantly slower speed (P = 0.019) and smaller toe-off angles (P = 0.007) were also observed during circular walking. In the ON state, the above effects remained, albeit moderately reduced. With regard to balance, significant differences between Parkinson's disease patients with and without peripheral neuropathy were observed in the OFF medication state during stance with closed eyes on a foam surface. In the ON states, these differences were no longer observable. We showed that peripheral neuropathy is common in Parkinson's disease and influences gait and balance parameters, as measured with mobile health-technology. Our study supports that peripheral neuropathy recognition and directed treatment should be pursued in order to improve gait in Parkinson's disease patients and minimize balance-related disability, targeting individualized medical care.

Abstract
There is not in Argentina publications regarding the presentation of patients with COVID-19 requiring hospitalized and emergency care in vulnerable populations (lower incomes and less education tend at greater risk for poor health status and healthcare access), and it has few reports in developing countries. The objective is to determine whether in the care of vulnerable patients, to succeed against COVID-19, multiple public health tools and interventions will be needed to minimize morbidity and mortality. The study is a prospective cohort investigation of patients with lab-confirmed COVID-19, who required to any of the Health Centers response from April 8, 2020, to August 18, 2020. In Buenos Aires Metropolitan Area (AMBA), April 8, 2020 the virus was identified in patients hospitalized in the "Southeast Network" (SN), AMBA. SN covering an area of 661 square kilometers, with 1.8 million inhabitants residing in urban, and rural areas. A total of 14 health centers with different levels of care complexity provide care to patients in the region. The information of each patient with COVID-19 evaluated by SN, was incorporated in an Epidemiological Dashboard. The investigation was designed and reported with consideration of observational studies in epidemiology. We describe the hospitals presentation and care of persons who required SN response and were ultimately diagnosed with COVID-19. From April 8, 2020, to August 18, 2020, were included 1495 patients with lab-confirmed COVID-19 in SN. A total of 58% patients were men, and the mean age (SD) was 48.9 (15.59) years. Eighty one percent patients with pre-existing diseases, most frequent hypertension and diabetes, but hypertension, chronic lung disease, and cardiovascular disease presented higher risk. A total of 13% were hospitalized in Intensive Therapy Unit. The mortality of the cohort was 9.77%. Mortality was higher for patients aged 65 or more (OR 5.09), and for those had some pre-existing disease (OR 2.61). Our observations are consistent with reports demonstrating older persons, and those with comorbidities have the highest risk of mortality related to COVID-19. However, unlike other reports from developed or some developing countries, the mortality in our study is lower. This finding may be related to age of our cohort is younger than other published. Also, the health system was able to respond to the demand.

Abstract
Background Chronic hepatic disease can present with extrapyramidal symptoms. We describe two cases that presented with highly unusual movement disorders: ballism and gait freezing. Case report Patient 1 is a 42-year-old man with previous episodes of hepatic encephalopathy (HE) who presented with upper limb dystonia and generalized chorea that progressed to ballism. Patient 2 is a 55-year-old woman who presented with pronounced gait freezing. In both patients, features of HE and acquired hepatocerebral degeneration coexisted. They improved markedly, though transiently, with rifaximin. Discussion Ammonia-reducing treatments should be considered in patients presenting with movement disorders due to chronic liver disease.

Abstract
Background Chorea may occur as a manifestation of an acute stroke. Patients with vascular-related chorea typically present with an acute or subacute onset of hemichorea, contralateral to the lesion. Methods and Findings In this clinico-pathological case, we report a 90-year-old female who presented, at age 81, with a transient episode of generalized chorea. Over the years, the patient continued to have intermittent episodes of generalized chorea or hemichorea, followed by a progressive dementia syndrome with gait and sphincter disturbance. There was no family history of chorea or dementia. Laboratory tests for paraneoplastic or autoimmune disorders and genetic testing for Huntington's disease were normal or negative. Magnetic resonance imaging showed subcortical and basal ganglia atrophy associated with ischemic leukoencephalopathy and lacunar infarcts. The post-mortem examination identified multiple lacunar infarcts (cortex, white matter, thalamus, basal ganglia) and minor Alzheimer's disease neuropathological changes. Conclusions Vascular disease, affecting the basal ganglia, is included in most lists of causes of generalized chorea. Proven cases are difficult to find. We present a rare case of vascular pathology causing late onset generalized and intermittent chorea. We highlight the intermittent nature of the chorea that could be explained by cumulative vascular lesions or functional disconnection in a previous deficient circuit.

Abstract
This study investigates the potential of an indigenous estuarine microbial consortium to degrade two polycyclic aromatic hydrocarbons (PAHs), naphthalene and fluoranthene, under nitrate-reducing conditions. Two physicochemically diverse sediment samples from the Lima Estuary (Portugal) were spiked individually with 25 mg L-1 of each PAH in laboratory designed microcosms. Sediments without PAHs and autoclaved sediments spiked with PAHs were run in parallel. Destructive sampling at the beginning and after 3, 6, 12, 30 and 63 weeks incubation was performed. Naphthalene and fluoranthene levels decreased over time with distinct degradation dynamics varying with sediment type. Next-generation sequencing (NGS) of 16 S rRNA gene amplicons revealed that the sediment type and incubation time were the main drivers influencing the microbial community structure rather than the impact of PAH amendments. Predicted microbial functional analyses revealed clear shifts and interrelationships between genes involved in anaerobic and aerobic degradation of PAHs and in the dissimilatory nitrate-reducing pathways (denitrification and dissimilatory nitrate reduction to ammonium - DNRA). These findings reinforced by clear biogeochemical denitrification signals (NO3- consumption, and NH4+ increased during the incubation period), suggest that naphthalene and fluoranthene degradation may be coupled with denitrification and DNRA metabolism. The results of this study contribute to the understanding of the dissimilatory nitrate-reducing pathways and help uncover their involvement in degradation of PAHs, which will be crucial for directing remediation strategies of PAH-contaminated anoxic sediments.

Abstract
IntroductionA considerable proportion of patients with morbid obesity require treatment with antidepressants.ObjectivesThe aim of this study is to determine the incidence of patients who are in antidepressant treatment and identify risk factors for the need of this treatment in patients with morbid obesity.Materials and methodsRetrospective cohort study of 292 patients with morbid obesity who underwent bariatric surgery at Hospital del Mar from January 2010 to November 2015. The incidence of antidepressant treatment was analyzed, and also its possible relationship with the following variables: age, sex, BMI, tobacco smoking, alcohol consumption and age of onset of obesity. Chi2 test for categorical variables and Student t-test for quantitative variables were applied. Afterwards, a multivariate analysis was performed using logistic regression.ResultsThe mean age is 43.1 years. Most of the patients (76.4%) are women. Seventy-seven patients (26.4%) are receiving treatment with antidepressants. There is a statistically significant relationship between age and the need of treatment with antidepressants (P < 0.001). This relationship is still present when the variables are analyzed using logistic regression (P < 0.005, OR 1.049). We have not found any significant relationship with the rest of the variables.ConclusionsDespite the large number of patients in the study, there are limitations, such as being a retrospective study and not being adjusted for confounding factors. From all the variables that have been analyzed we have found that as the age of the patients increase, there is a higher number of patients that receive treatment with antidepressants.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionImpairment of insight in psychotic disorder is associated with adverse impact in treatment compliance, outcome and social functioning although its underlying mechanisms are still unknown. Social cognition and more specifically Theory of mind have been proposed to be correlated to insight. However, the relationship between both factors is still not well defined.AimsTo study the association between social cognition and insight into mental illness in individuals with early psychosis included in the first episode of psychosis program of Hospital del Mar.MethodsFrom the 94 patients included in the first psychotic episode program between January 2011 and January 2016, thirty-eight patients were evaluated six months after the episode. The three initial items of SUMD (Scale Unawareness of Mental Disorder) were used to measure insight and MSCEIT (Mayer-Salovey-Caruso Emotional Intelligence Test) was used to assess social cognition. Linear correlation analysis by Pearson correlation was conducted.ResultsInsight results of SUMD six months after the first episode of psychosis were significantly associated with several subsections of MSCEIT, such as experiential area total punctuation (r = –0.574; P = 0.025), emotional facilitation section (r = –0.633; P = 0.011) and the facial emotion perception task (r = –0.572; P = 0.026).ConclusionsResults suggest an association between insight and emotional perception and facilitation performance in first episode patients, which may suggest a role of social cognition in psychosis insight impairment. Further research to better define the participation of social cognition in insight into psychosis alteration is mandatory to understand the etiology of insight, define treatment targets and consequently improve the disorder prognosis.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionDespite multiple clinical and preclinical studies investigating schizophrenia, the neurobiological basis of this disease is still unknown. The dysregulation of the serotonergic system, in particular the 5-HT2A receptor and the endocannabinoid system have been postulated as possible causes of schizophrenia.ObjectivesThe aim of this study is to evaluate the expression of CB1-5-HT2A receptor heteromers in primary cultures of pro-neurons from the olfactory epithelium in schizophrenia patients and control subjects.MethodsWe recruited a group of 10 healthy volunteers and 10 patients diagnosed with schizophrenia, who were treated with atypical antipsychotics, were clinically stable and had an illness duration range from 1 up to 15 years. The patients were diagnosed with schizophrenia from the medical record and confirmed by the structured clinical interview for DSM disorders. The expression of CB1-5-HT2A receptor heteromers in primary cultures of pro-neurons from the olfactory epithelium was quantified using proximity ligation assays and confocal microscopy.ResultsOlfactory epithelium pro-neurons were viable and expressed the neuronal marker, III-β tubulin. We also established the presence and the functionality of CB1-5-HT2A receptor heteromers in these cells using the proximity ligation and cAMP activity assays, respectively. Heteromer expression was significantly increased in schizophrenia patients with respect to controls.ConclusionsThis highly innovative methodology will allow the noninvasive, low-cost study of new biomarkers for schizophrenia in a model closely related to the central nervous system.Disclosure of interestThe authors have not supplied their declaration of competing interest.AcknowledgmentsThis work was supported by grants from DIUE-Generalitat-de Catalunya (2014SGR 680), Instituto de Salud Carlos III (PI14/00210) and (PI10/01708) FIS-FEDER-Funds.

Abstract
BACKGROUND A unified set of criteria for neurocysticercosis (NCC) has helped to standardize its diagnosis in different settings. METHODS Cysticercosis experts were convened to update current diagnostic criteria for NCC according to two principles: neuroimaging studies are essential for diagnosis, and all other information provides indirect evidence favoring the diagnosis. Recent diagnostic advances were incorporated to this revised set. RESULTS This revised set is structured in absolute, neuroimaging and clinical/exposure criteria. Absolute criteria include: histological confirmation of parasites, evidence of subretinal cysts, and demonstration of the scolex within a cyst. Neuroimaging criteria are categorized as major (cystic lesions without scolex, enhancing lesions, multilobulated cysts, and calcifications), confirmative (resolution of cysts after cysticidal drug therapy, spontaneous resolution of single enhancing lesions, and migrating ventricular cysts on sequential neuroimaging studies) and minor (hydrocephalus and leptomeningeal enhancement). Clinical/exposure criteria include: detection of anticysticercal antibodies or cysticercal antigens by well-standardized tests, systemic cysticercosis, evidence of a household Taenia carrier, suggestive clinical manifestations, and residency in endemic areas. Besides patients having absolute criteria, definitive diagnosis can be made in those having two major neuroimaging criteria (or one major plus one confirmative criteria) plus exposure. For patients presenting with one major and one minor neuroimaging criteria plus exposure, definitive diagnosis of NCC requires the exclusion of confounding pathologies. Probable diagnosis is reserved for individuals presenting with one neuroimaging criteria plus strong evidence of exposure. CONCLUSIONS This revised set of diagnostic criteria provides simpler definitions and may facilitate its more uniform and widespread applicability in different scenarios.

Abstract
The rapid spread of multidrug-resistant bacteria has become a serious threat, especially in critical care units, thereby prolonging the hospital stay. Enterobacteriaceae have a high capacity to adapt to any environment. Plasmids are the reason behind their expansion. The choice of empiric therapy for intra-abdominal or urinary infections requires knowledge of the intrinsic microbiological variability of each hospital or critical care unit, as well as the source of infection, safety or antibiotic toxicity, interaction with other drugs, the dosage regimen and the presence of risk factors. Carbapenems are the drug of choice in the case of suspected infection by ESBL-producing Enterobacteriaceae. The new ceftazidime/avibactam and ceftolozane/tazobactam drugs are opening up promising new horizons in the treatment of multidrug-resistant Enterobacteriaceae.

Abstract
Denitrification and anammox are key processes for reducing the external nitrogen loads delivered to coastal ecosystems, and these processes can be affected by pollutants. In this study, we investigated the effect of crude oil on denitrification and anammox. Controlled laboratory experiments were performed using sediment slurries from the Lima Estuary (NW Portugal). Anammox and denitrification rates were measured using (15)N-labeled NO3(-), and the production of (29)N2 and (30)N2 quantified by membrane inlet mass spectrometry. Results revealed that while denitrification rates were stimulated between 10 and 25 000 times after crude oil amendment, anammox activity was partially (between 2 and 5 times) or completely inhibited by the addition of crude oil when comparing to rates in unamended controls. Similar results were observed across four estuarine sediment types, despite their different physical-chemical characteristics. Moreover, N2O production was reduced by 2-36 times following crude oil addition. Further work is required to fully understand the mechanism(s) of the observed reduction in N2O production. This study represents one of the first contributions to the understanding of the impact of crude oil pollution on denitrification and anammox, with profound implications for the management of aquatic ecosystems regarding eutrophication (N-removal).

Abstract
Introduction and objectivesMechanical restraint is a therapeutic procedure commonly applied in acute units in response to psychomotor agitation. Its frequency is between 21 and 59% of patients admitted. These patients represent a risk to both themselves and for health workers. There is a myth that patients with substance use disorder (SUD) are more aggressive and require more forceful measures. There are not clinical studies that compared if there are differences of the frequency of mechanical restrain in patients with SUD.The aim of this study is to explore the differences of frequency of mechanical restraint on patients with SUD in the psychiatry acute and dual pathology units and others psychiatric diagnostics.Material and methodsWe reviewed retrospectively the informatics record of all the mechanical restraints made and the total discharges of the three acute care units and dual disorders of Neuropsychiatry and Addictions Institute (INAD) of the Parc de Salut Mar de Barcelona, between January 2012 and January 2015. For every discharge the presence of at least one mechanical restraint and the DSM-IV diagnostic were coded. Then was calculated the frequency and proportion of mechanical retrains in every diagnostic group.ResultsThe number of discharges analyzed was 4659 from which 838 had an episode of mechanical restraint. The 37% of patients with SUD of cocaine had an episode of mechanical restrain. The patients with SUD of alcohol only the 4%, and there no one case on patients with SUD of Cannabis. Thirty percent of patients with schizophrenia and 28% of bipolar disorder.AcknowledgementsL.

Abstract
IntroductionPsychomotor agitation is a common psychiatric emergency in our environment that can occur in a wide clinical spectrum. Both the agitation itself as the procedures for their control, carry an implicit risk to patient safety and health workers.ObjectiveTo describe the prevention measures used in patients requiring mechanical restraint in relation to diagnosis of psychiatric disorders.Material and methodsThis is a naturalistic descriptive study. Mechanical restraints made in brief psychiatric hospitalization units of “Hospital del Mar” between January of 2013 to March of 2015, were analyzed by diagnosis. Proportions of the prevention intervention performed by nurses in each episode were compared. The groups of prevention interventions done were: “verbal approach”, “environmental measures”, “psychopharmacological intervention”, “observation increase” and “inability for applying any measure because unpredictability”.ResultsA total of 2986 mechanical restraints were done in brief hospitalization units. Among the results, we find that verbal approach measure was use in 77.23% of patient with personality disorders. Environmental measures were used in 40% of the total of restraints. The most of psychopharmacological intervention was done in alcohol intoxication (50%) and then in psychotic spectrum (42.01%). The inability for applying measures was greater in alcohol intoxication (45.4%).ConclusionSome of the results of this study are interesting and consistent with clinical practice (for example, effectivity of pharmacological intervention in psychosis and bipolar disorders, as well verbal approach in anxiety, etc.), we can predict the usefulness of measures applied to prevent a mechanical restraint. Further research is needed in this topic.Disclosure of interestL. Galindo is a Rio-Hortega-fellowship – (ISC-III; CM14/00111).

Abstract
The organic sulfur compound 3-mercaptopropionic acid (3-MPA) is an important thiol intermediate in organic sulfur metabolism in natural environments. It is generated during degradation of sulfur-containing amino acids (e.g. methionine) and from demethylation of dimethylsulfoniopropionate (DMSP). This pathway is an alternative enzymatic process in the DMSP catabolism that routes sulfur away from the climatically-active dimethyl sulfide (DMS). 3-MPA detection and subsequent quantification in different matrices is difficult due to its extreme reactivity. We therefore developed a sensitive method for determination of 3-MPA based on pre-column derivatization with monobromobimane and analysis by high-performance liquid chromatography (HPLC) with fluorescence detection. This methodology was first tested with 3-MPA standards under low (0.005-0.2μmolL(-1)) and high (1-25μmolL(-1)) concentrations. For the optimization of the reaction, CHES and, alternatively, Tris-HCl buffers were evaluated in the derivatization step, with Tris-HCl showing more effective separation of thiol derivatives and a better 3-MPA peak shape. The detection limit was 4.3nmolL(-1) with a 10μL sample injection, and mean recoveries of 3-MPA ranged from 97 to 105% in estuarine waters with different salinities (0.17 and 35.9ppt). The linearity (r>0.99) and repeatability of detector response, with intra- and inter-day precision (% CV) of 2.68-7.01% and 4.86-12.5%, respectively, confirmed the reliability of the method. Previous 3-MPA analytical methods required immediate analysis due to unstable derivatives, but in this method we achieved high stability of the derivatized samples when stored at 4°C, with only a 3-5% loss after more than one year of storage. This method was successfully applied to measure 3-MPA concentrations and rates of 3-MPA production in a variety of intertidal estuarine sediment slurries. Dissolved 3-MPA concentrations in these sediment slurries varied between 2 and 237μmolL(-1) and, 3-MPA net fluxes ranged in wet sediments between -3.6±1.7 and 30±5μmolL(-1)g(-1)h(-1). Thus, the application of this optimized methodology showed an efficient performance for measuring 3-MPA in environmental samples, with a straightforward sample derivatization and a simple analysis of stable 3-MPA derivatives.

Abstract
The fate of excess nitrogen in estuaries is determined by the microbial-driven nitrogen cycle, being denitrification a key process since it definitely removes fixed nitrogen as N2. However, estuaries receive and retain metals, which may negatively affect this process efficiency. In this study, we evaluated the role of salt marsh plants in mediating cadmium (Cd) impact on microbial denitrification process. Juncus maritimus and Phragmites australis from an estuary were collected together with the sediment involving their roots, each placed in vessels and maintained in a greenhouse, exposed to natural light, with tides simulation. Similar non-vegetated sediment vessels were prepared. After 3 weeks of accommodation, nine vessels (three per plant species plus three non-vegetated) were doped with 20 mg/L Cd(2+) saline solution, nine vessels were doped with 2 mg/L Cd(2+) saline solution and nine vessels were left undoped. After 10 weeks, vessels were dissembled and denitrification potential was measured in sediment slurries. Results revealed that the addition of Cd did not cause an effect on the denitrification process in non-vegetated sediment but had a clear stimulation in colonized ones (39 % for P. australis and 36 % for J. maritimus). In addition, this increase on denitrification rates was followed by a decrease on N2O emissions and on N2O/N2 ratios in both J. maritimus and P. australis sediments, increasing the efficiency of the N2O step of denitrification pathway. Therefore, our results suggested that the presence of salt marsh plants functioned as key mediators on the degree of Cd impact on microbial denitrification.

Abstract
BACKGROUND AND AIMS Accumulating evidence indicates that a state of chronic inflammation has a crucial role in the pathogenesis of obesity-related metabolic dysfunction. This study aims to evaluate changes in inflammatory process, iron metabolism, erythropoiesis, and lipid profile associated with weight loss after gastric banding surgery. MATERIAL AND METHODS A total of 46 patients were evaluated before and 3 months after gastric banding surgery. A survey was conducted to record demographic data, body mass index, and presence of comorbidities. Moreover, complete blood cell counts and serum levels of iron, ferritin, transferrin, high-sensitivity C-reactive protein, total cholesterol, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, and triglycerides were performed. RESULTS At a follow-up 3 months after surgery, our patients presented a significant decrease in weight and body mass index, associated with a decreased inflammatory process (decreased high-sensitivity C-reactive protein, neutrophil counts, and neutrophil:lymphocyte ratio), increased iron availability (increased transferrin saturation and a trend to higher iron serum levels), and significant decreased triglycerides and triglycerides:high-density lipoprotein-cholesterol ratio. CONCLUSIONS Our results showed a significant decrease in the inflammation process 3 months after gastric banding surgery, associated with adipose tissue loss. This decrease in the inflammatory process is associated with more efficient iron absorption and increased iron availability for erythropoiesis. Moreover, we also found decreased triglyceride serum levels. These changes suggest benefits of weight loss, including decreased risk of cardiovascular disease.

Abstract
The use of heavy water (D(2)O) as a solvent is commonplace in many spectroscopic techniques for the study of biological macromolecules. A significant deuterium isotope effect exists where hydrogen-bonding is important, such as in protein stability, dynamics and assembly. Here we illustrate the use of D(2)O in additive screening for the production of reproducible diffraction-quality crystals for the Salmonella enteritidis fimbriae 14 (SEF14) putative tip adhesin, SefD.

Abstract
OBJECTIVE To determine brain areas reduced in first episode of psychotic subjects and its association with lack of insight and negative symptoms. METHOD Twenty-one drug naive first-episode subjects and 20 controls underwent a structural MRI scan and were clinically assessed. Optimized voxel-based-morphometry analysis (VBM) was implemented to find between-group differences and correlations between GM volume and: (i) lack of insight and (ii) negative symptoms. RESULTS Patients showed GM reduction in prefrontal and left temporal areas. A significant correlation was found between insight and GM volume in the cerebellum (corrected P = 0.01), inferior temporal gyrus (corrected P = 0.022), medial superior frontal gyrus (corrected P < 0.001), and inferior frontal gyrus (corrected P = 0.012), as the insight decreased, the volume decreased. Negative symptoms correlated with decreased GM volume at cerebellum (corrected P = 0.037) and frontal inferior regions (corrected P < 0.001), the more negative symptoms, the less volume. CONCLUSION Our findings support an association between prefrontal, temporal, and cerebellar deficits and lack of insight in schizophrenia and confirm previous findings of GM deficits in patients since the first episode of psychosis.

Abstract
Introduction:Diagnostic stability in first-episode psychosis shows a wide variability between studies. Amini and cols reported a 50% rate of patients schizophreniform disorder shifting to schizophrenia during the first 12 months period. We report the preliminary follow-up results of our recently ongoing first- episode psychosis unit.Methods:Forty-six patients admitted for a first-episode psichosis to our Inpatient Psychiatric Unit from January 2006 to January 2008 were recruited. Clinical and socio-demographic characteristics were registered during admission period and during the follow-up period.Results:At admission 52% of the first-episode subjects had a diagnosis of psychosis NOS and 32% a schizophreniform disorder diagnosis. after discharge, most of the patients (72%) had a diagnosis of schizophreniform disorder, 16% psychosis NOS and 8% brief psychotic disorder. Six months later, half of the followed-up patients had a schizophreniform disorder diagnosis, and 23% had a diagnosis of schizophrenia. 30% of the patients were drop-outs, mainly referred to other out-patient services. Patients shifting to schizophrenia were younger, predominantly male (75% vs 50% in non-schizophrenia shift), had a lower proportion of university studies and presented a longer hospitalization period at admission. No differences in familial history of psychosis and cannabis use were found. after one-year follow-up period, 50% preserved a schizophreniform disorder diagnosis and 30% were diagnosed as schizophrenia.Conclusions:Schizophrenia spectrum disorders have a high stability in first-episode psychosis during first year follow-up. as in previous studies, male gender is one of the factors that best predicts the shift to schizophrenia.

Abstract
BACKGROUND After variceal bleeding, cirrhotic patients should receive secondary prophylaxis. AIM To compare nadolol plus 5-isosorbide mononitrate (5-ISMN) with endoscopic band ligation. The end points were rebleeding, treatment failure and death. METHODS One hundred and nine cirrhotic patients with a recent variceal bleeding were randomized: nadolol plus 5-ISMN in 57 patients and endoscopic band ligation in 52 patients. RESULTS The mean follow-up was 17 and 19 months in nadolol plus 5-ISMN and endoscopic band ligation groups, respectively. No differences were observed between groups in upper rebleeding (47% vs. 46%), variceal rebleeding (40% vs. 36%), failure (32% vs. 22%), major complications (7% vs. 13.5%) and death (19% vs. 20%), respectively. The actuarial probability of remaining free of rebleeding, failure and deaths were similar in both groups. Time to rebleeding shows that endoscopic band ligation patients had an early rebleed, with a median of 0.5 month (95% CI: 0.0-4.2) compared with patients from nadolol plus 5-ISMN, 7.6 months (95% CI: 2.9-12.3, P < 0.013). Multivariate analysis indicated that outcome-specific predictive factor(s) for rebleeding was Child A vs. B + C (P < 0.01); for failure was Child A vs. B + C (P < 0.02); and for death ascites (P < 0.01) and rebleeding (P < 0.02). CONCLUSION This trial suggests no superiority of endoscopic band ligation over nadolol plus 5-ISMN mononitrate for the prevention of rebleeding in cirrhotic patients.

Abstract
OBJECTIVE We developed new subroutines and scoring procedures of the CDT to detect markers of early cognitive impairment. SUBJECTS AND METHODS We compared the performance of 41 mild Alzheimer's patients (AD) (MMSE 22.7+/-3.2); and 18 mild cognitive impairment patients (MCI) (MMSE 28.3+/-1.4), with 33 age and education matched normal controls (NC) regarding their ability in drawing a clock on command, copying a printed clock, setting hands and reading the time. We search for differences in the placement of the hands using a colloquial hour code ("a quarter to ten") and a formal numeric code ("10:45"). We focused our attention on placement and clock hands size. The drawing of hands pointing at 2:50 hs and 8:40 hs were of particular interest. RESULTS Planning strategies, placement of clock hands using a formal numeric code, clock hands size and hands drawing pointing at 2:50 hs. and 8:40 hs. were the variables that best discriminated AD, MCI and NC ( p<0.01). A stepwise regression analysis using as dependent variables (AD - NC ) and (MCI - NC) showed in both cases that the best predictor model was that formed by: planning strategies, clock hands pointing to 8:40, clock hands size, reading hours and set up clock hands following a formal numeric code (p<.001). CONCLUSIONS Our proposed modifications in this test convert it in an appropriate tool for cognitive impairment screening because they do not only detect visuoconstructional abilities but also frontal planning, contents and processing of the hour memory code and transcodification of semantic memory processes.

Abstract
OBJECTIVE The purpose of this study is to identify specific clinical-electroencephalogram (EEG) patterns at seizure onset in patients with hippocampal sclerosis (HS). METHODS Sixty-six ictal video-EEG recordings corresponding to 26 patients with HS have been reviewed, focusing on the EEG features found during the first 30 ictal s. The EEG activity has been classified into the following groups: (A) according to spatial distribution: type 1: temporal electrodes on one side; type 2: temporal and adjacent frontal electrodes on one side; and type 3: non-lateralizing electrographic activity; and (B) according to morphology; subtype (a): regular 5-9 Hz rhythmic activity (RA); subtype (b): low-voltage rapid activity, followed by a 5-9 Hz RA; and subtype (c): irregular EEG sharp waves. We analyzed the clinical symptoms sequence and established the relationship with the ictal EEG patterns. RESULTS Considering spatial distribution and morphology, the most frequent ictal EEG patterns were type 1 (57%), type 2 (37%), and subtype (a): 62%; subtype (b): 27%; and subtype (c): 11%. The sequence of clinical symptoms observed was: aura-->behavioral arrest-->oro-alimentary automatisms-->unilateral hand automatisms. All seizures with aura and including two or more symptoms of the clinical sequence (65%) were associated with a 1a, 1b, 2a or 2b EEG pattern. CONCLUSIONS The identification of a specific clinical-EEG pattern provides a useful tool for the epileptogenic zone localization in non-invasive pre-surgical assessment of patients with hippocampal sclerosis. SIGNIFICANCE The identification of a specific clinical-EEG pattern associated to neuroimaging findings and neuropsychological testing allows indicating surgery for the treatment of epilepsy in patients with hippocampal sclerosis, without performing any further complementary studies.

INTRODUCTION With the aim of integrating clinical thinking and obtaining epidemiological and biostatistical results in long series of patients who present balance disorders, we have developed a neuro otological protocol and its corresponding database. This offers answers to the questions of how to assess the patient, how to conduct a clinical interview correctly, and which complementary studies should be requested and how. RESULTS The information from the protocol is stored and analysed in our database, which was designed in the Epi Info software application, produced by CDC (NIH, USA), in collaboration with the WHO Global Program on AIDS. The application, which we call ENO LK, has already been used to store data concerning 1,100 patients whose average age is 54.5 years old and 62.8% of which were females (SD 18, range 4 93). 69.1% were diagnosed as suffering from vertigo, 12.7% displayed instability, 1.9% syncope and 16.3% had other causes (37% psychogenic and 28% disorders affecting the central integrator). Of the 760 patients with vertigo, in 55% it was positional (60% of these were idiopathic benign), 6.3% were sustained (peripheral causes accounted for 74% and a vascular aetiology was predominant in the central causes), 26.6% were recurring and 12.1% otolithic (in this series the vertigos all had a central aetiology). CONCLUSIONS With this application the user has the possibility of obtaining epidemiological and diagnostic conclusions efficiently and effectively, as well as aiding to follow up all patients who present balance disorders.

Abstract
PATIENTS AND METHODS We analysed the records of the individuals who were attended because of dizziness or vertigo in the vestibular sector, with the aim of describing the epidemiological clinical profile of a group of patients with such symptoms. 1300 patients were systematically evaluated according to our neuro otological examination protocol. Diagnoses were ordered, according to the international classification reported by Drachman and later modified by Bahlo, in four categories: 1. Vertigo, 2. Instability, 3. Pre syncope and 4. Miscellaneous. Each of these classes was organised according to the topography of the lesion and these were in turn grouped by aetiologies (viral, vascular, tumoural, demyelinating, post traumatic, idiopathic, autoimmune, etc.). The data were stored and analysed in a computer database, Epi info 6.02 (OMS 1994), which was especially adapted by the researchers for the purpose. RESULTS 63.1% were women. The average age was 55.5 years old (SD: 17.5, interval: 4 93). Vertigo was diagnosed in 68.9%, instability was found in 12.4%, 1.8% presented syncope and miscellaneous disorders occurred in 16.9% (of these, 64.1% had disorders of the central integrator and 16.4% were of a psychogenic origin). Of the 1300 patients, 896 presented vertigo; the positional type was seen in 54%, sustained in 6.5%, recurrent in 27.7% and 11.8% were found to have the otolithic type. CONCLUSIONS The relevance of the epidemiological work based on clinical evaluation and the thorough neuro otological examination in our medium must be highlighted. These findings were similar to those reported in the international literature in more delimited series.

Abstract
Obsessive-compulsive disorder (OCD) has been related to frontostriatal dysfunction, but some inconsistencies between studies and a relative paucity of neuropsychological research still characterizes the study of OCD. We compared 28 patients with OCD and matched healthy controls on two neuropsychological tests sensitive to frontal dysfunction: temporal ordering and a "feeling-of-doing" (FOD) judgment about ordering. The OCD group performed significantly worse than controls in the temporal ordering task despite showing normal recognition memory. Patients were also impaired in "feeling-of-doing" judgments suggesting they have a lack of self-awareness of their performance. Thus, the results of the current study reinforces previous research that indicates that OCD patients fail on tasks that require adequate functioning of the frontal-striatal pathways.

Abstract
The aim of our study was to investigate whether patients with obsessive-compulsive disorder (OCD) have impaired incidental memory for frequency. Fifty-four subjects (27 OCD patients and 27 matched control subjects) performed a task assessing estimation of occurrence of previously heard words. Performance on this task was compared with other intentional verbal memory tasks (recognition, recall and learning of common words). We also correlated memory for frequency with frontal lobe tests (Wisconsin Card Sorting Test, Trail Making Tests A and B, and verbal fluency). Performance on incidental learning of frequency was significantly worse in the OCD group than in control subjects. Other verbal memory measures did not show significant differences. Performance in the frequency task correlated with verbal fluency. Although intentional verbal memories are normal in OCD patients, incidental memory for frequency is impaired, suggesting that prefrontal systems are involved in OCD.

Abstract
BACKGROUND The objective of this study was to examine the long-term course of obsessive-compulsive disorder (OCD) in patients treated with serotonin reuptake inhibitors (SRIs) and behavioral therapy and to identify predictors of clinical outcome. METHOD Sixty outpatients meeting DSM-II-R or DSM-IV criteria for OCD were followed up for 1 to 5 years (mean = 2.5 years). All of them received prolonged pharmacologic therapy with an SRI. RESULTS Thirty-seven patients (61.7%) completed an adequate behavioral treatment. At long-term assessment, 22 patients (36.7%) exhibited a global Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score greater than 16 or a final reduction in Y-BOCS global score of less than 35% and were considered nonresponders. Patients who completed behavioral therapy showed a significant decrease in Y-BOCS compulsions subscale score (p = .01), whereas no significant differences in either Y-BOCS global or obsessions subscale scores between those who did and those who did not undergo behavioral therapy were detected. Obsessions of sexual/religious content were the unique factor related to a poorer long-term outcome. CONCLUSION A substantial number of OCD patients showed persistent disabling symptoms at the long-term follow-up in spite of combined pharmacologic and behavioral treatment. Major benefits from behavioral therapy appeared to be the improvement of ritualistic behaviors. Sexual/religious obsessions predicted poorer long-term outcome, whereas short-term response to SRI treatment failed to achieve predictive value in the long-term course of OCD.
