Concomitant treatment with safinamide and antidepressant drugs: Safety data from real clinical practice.

BACKGROUND AND PURPOSE: The aim of this study was to assess the possible pharmacological interactions between safinamide and antidepressants, and in particular the appearance of serotonin syndrome with data from real life. METHODS: We conducted a retrospective observational study of patients with Parkinson's disease from our Movement Disorders Unit, who were under treatment with any antidepressant drug and safinamide. Specifically, symptoms suggestive of serotonin syndrome were screened for. Also, we collected time of simultaneous use, doses of levodopa and other antiparkinsonian drugs. RESULTS: Clinical records were reviewed for the study period of September 2018 to September 2019. Seventy-eight PD patients who were treated with safinamide of which 25 (32.05%) had a concomitant treatment with an antidepressant drug, being sertraline and escitalopram the most frequent. Mean age was 80 years±8.43 and H&Y stage was 3 [2-4]. Mean dose of levodopa used was 703.75mg±233.15. Median duration of concomitant treatment with safinamide and antidepressant drug was 6 months (IQR 20.5), and over eighteen months in 5 cases. No case of serotonin syndrome was recorded, neither was any of its typical manifestations combined or in isolation. CONCLUSIONS: Our real clinical practice study suggests that concomitant use of safinamide with antidepressant drugs in PD patients seemed to be safe and well tolerated, even in the long term. However, caution is warranted, individualizing treatment regimens and monitoring the potential appearance of adverse effects.

[What do medical students think about functional neurological disorders?] / ¿Qué piensan los estudiantes de Medicina sobre los trastornos neurológicos funcionales?

INTRODUCTION: Functional neurological disorders (FND) are a frequent reason for visits in neurology. However, specific training on these disorders during undergraduate and residency training is limited. This study assesses the knowledge, attitude and exposure of medical students to FNDs before completing their medical degree. PATIENTS AND METHODS: We conducted a 15-item survey to explore understanding, exposure and attitudes towards FNDs among sixth-year medical students at four Spanish universities. RESULTS: A total of 118 students (mean age 23.6 ± 1.2 years; 71.2% female) returned the survey. Of these, 88 (74.6%) were aware of the concept of FNDs and 78 (66.1%) had studied them in psychiatry classes. The term 'psychosomatic' was chosen by 54.1% of the students as the most appropriate term to refer to these disorders, and 111 (94.1%) believed that a history of sexual or physical abuse was common among FND patients. Fifty-seven students (48.3%) assumed that the diagnosis of FND was mostly a clinical diagnosis of exclusion and 63 (53.4%) indicated that it is managed only by psychiatry. One hundred and one students (85.6%) considered that adequate training on FNDs is an important aspect of their medical training. CONCLUSIONS: Medical students are aware of the existence of FNDs, but their preferred terminology, as well as the perceived aetiological factors, reflect that the historical view of these disorders is still deeply rooted. Medical students feel that they should receive adequate education on FNDs from specialists in neurology and psychiatry as part of their training.

TITLE: ¿Qué piensan los estudiantes de Medicina sobre los trastornos neurológicos funcionales?Introducción. Los trastornos neurológicos funcionales (TNF) son un motivo de consulta frecuente en neurología. Sin embargo, la formación específica sobre estos trastornos durante la formación universitaria y el período de residencia es limitada. En este estudio se evalúan los conocimientos, la actitud y la exposición de los estudiantes de Medicina a los TNF antes de terminar el grado de Medicina. Sujetos y métodos. Realizamos una encuesta de 15 ítems para explorar la comprensión, la exposición y las actitudes hacia los TNF entre los estudiantes de Medicina de sexto año en cuatro universidades españolas. Resultados. Devolvieron la encuesta 118 estudiantes (edad media 23,6 ± 1,2 años; 71,2%, mujeres). De ellos, 88 (74,6%) conocían el concepto de TNF y 78 (66,1%) los habían estudiado en las clases de psiquiatría. El 54,1% de los estudiantes eligió el término 'psicosomático' como el más adecuado para referirse a estos trastornos, y 111 (94,1%) creían que una historia de abuso sexual o físico era común entre los pacientes con TNF. Cincuenta y siete estudiantes (48,3%) asumieron que el diagnóstico de TNF era mayoritariamente un diagnóstico clínico de exclusión y 63 (53,4%) señalaron que el manejo se realiza únicamente desde psiquiatría. Ciento un estudiantes (85,6%) consideraron que una formación adecuada sobre los TNF es un aspecto importante de su formación médica. Conclusiones. Los estudiantes de Medicina son conscientes de la existencia de los TNF, pero la terminología preferida por ellos, así como los factores etiológicos percibidos, reflejan que la visión histórica acerca de estos trastornos está aún arraigada. Los estudiantes de Medicina consideran que deberían recibir una educación adecuada sobre los TNF como parte de su formación por parte de los especialistas en neurología y psiquiatría.

[Apomorphine: a powerful ally in Parkinson's disease]. / Apomorfina: un poderoso aliado en la enfermedad de Parkinson.

INTRODUCTION: Apomorphine, a D1-D2 dopamine agonist, is the oldest drug with proven efficacy in the treatment of Parkinson's disease (PD), and the only with similar symptomatic power to levodopa. Its usefulness in the control of motor fluctuations, both as intermittent injections and in continuous subcutaneous infusion, has been demonstrated in open label and placebo controlled trials. AIM: To analyse the role of apomorphine in the varied clinical symptoms and different clinical stages of PD through a narrative review of scientific literature (1951-2020). DEVELOPMENT: Beyond on-time increase, off-time decrease, off dystonia and quality of life improvement in advanced PD, there is evidence to support a role of apomorphine in less known clinical areas of PD, such as non motor symptoms, a lower risk of impulse control disorders, potential to ameliorate visual hallucinations, improve neuropsychiatric symptoms and dyskinesia and even axial features. Nevertheless, the optimal timing of apomorphine treatment remains controversial, and its implementation of this valuable drug in clinical practice has been historically hindered by several factors. CONCLUSIONS: Apomorphine is a unique drug in the PD treatment scenario, with a number of potential applications beyond motor fluctuations control. Acknowledging these properties, selecting the patient most likely to benefit from it and finding the right timing may be key in the symptomatic control of this complex disease.

TITLE: Apomorfina: un poderoso aliado en la enfermedad de Parkinson.Introducción. La apomorfina, agonista dopaminérgico D1 y D2, es el fármaco más antiguo con efectividad en el tratamiento de la enfermedad de Parkinson (EP) y el único de potencia análoga a la levodopa. Su utilidad, tanto en la administración intermitente como en la perfusión continua en el control de las fluctuaciones motoras, está demostrada tanto en estudios abiertos como controlados. Objetivo. Analizar el papel de la apomorfina en las distintas manifestaciones y momentos evolutivos de la EP mediante una revisión narrativa de la literatura científica (1951-2020). Desarrollo. Más allá del aumento de la duración del on, la reducción del off, la mejoría de la distonía en off y la calidad de vida en pacientes con EP avanzada, existe evidencia de la efectividad de la apomorfina en áreas menos conocidas de la EP, como síntomas no motores, menor riesgo de inducir trastornos de control de impulsos, potencial para atenuar las alucinaciones visuales, mejora de la clínica neuropsiquiátrica asociada a la EP, ayuda a un mejor control de las discinesias o influencia en los síntomas axiales. Sin embargo, el momento óptimo de su instauración sigue siendo objeto de debate, y existen varios factores que históricamente han limitado el uso de este valioso fármaco. Conclusiones. La apomorfina es un fármaco con propiedades únicas dentro del abanico de posibilidades para tratar la EP, con potenciales aplicaciones más allá del control de las fluctuaciones motoras. Conocerlas para indicarlas a los pacientes que más puedan beneficiarse de ellos, así como valorar adecuadamente el estadio de la EP en que iniciar la apomorfina, puede ser clave para mejorar el control clínico de esta compleja patología.

Management of Parkinson's disease and other movement disorders in woman of childbearing age: Part 1. / Manejo de la enfermedad de Parkinson y otros trastornos del movimiento en mujeres en edad fértil: Parte 1.

INTRODUCTION: The main challenge of Parkinson's disease in women of childbearing age is managing symptoms and drugs during pregnancy and breastfeeding. The increase in the age at which women are having children makes it likely that these pregnancies will become more common in future. OBJECTIVES: This study aims to define the clinical characteristics of women of childbearing age with Parkinson's disease and the factors affecting their lives, and to establish a series of guidelines for managing pregnancy in these patients. RESULTS: This consensus document was developed through an exhaustive literature search and a discussion of the available evidence by a group of movement disorder experts from the Spanish Society of Neurology. CONCLUSIONS: Parkinson's disease affects all aspects of sexual and reproductive health in women of childbearing age. Pregnancy should be well planned to minimise teratogenic risk. A multidisciplinary approach should be adopted in the management of these patients in order to take all relevant considerations into account.

Management of Parkinson's disease and other movement disorders in women of childbearing age: Part 2. / Manejo de la enfermedad de Parkinson y otros trastornos del movimiento en mujeres en edad fértil: parte 2.

INTRODUCTION: Many diseases associated with hyperkinetic movement disorders manifest in women of childbearing age. It is important to understand the risks of these diseases during pregnancy, and the potential risks of treatment for the fetus. OBJECTIVES: This study aims to define the clinical characteristics and the factors affecting the lives of women of childbearing age with dystonia, chorea, Tourette syndrome, tremor, and restless legs syndrome, and to establish guidelines for management of pregnancy and breastfeeding in these patients. RESULTS: This consensus document was developed through an exhaustive literature search and a discussion of the content by a group of movement disorder experts from the Spanish Society of Neurology. CONCLUSIONS: We must evaluate the risks and benefits of treatment in all women with hyperkinetic movement disorders, whether pre-existing or with onset during pregnancy, and aim to reduce effective doses as much as possible or to administer drugs only when necessary. In hereditary diseases, families should be offered genetic counselling. It is important to recognise movement disorders triggered during pregnancy, such as certain types of chorea and restless legs syndrome.

COVID-19 in Parkinson's disease: what holds the key?

INTRODUCTION: Parkinson's disease (PD) is more frequent in the elderly and increases the risk of respiratory infections. Previous data on PD and SARS-CoV-2 are scarce, suggesting a poor prognosis in advanced disease and second-line therapies. METHODS: A retrospective case-control study comparing patients with PD and COVID-19 and patients with PD without COVID-19 was conducted during the pandemic period in Spain (March 1st-July 31st 2020) in a tertiary university hospital. RESULTS: Thirty-nine (COVID-19 +) and 172 (COVID-19-) PD patients were included. Fifty-nine percent were males in both groups, with similar age (75.9 ± 9.0 COVID-19 + , 73.9 ± 10.0 COVID-19-), disease duration (8.9 ± 6.2 COVID-19 + , 8.5 ± 5.6 COVID-19-) and PD treatments. COVID-19 was mild in 10 (26%), required admission in 21 (54%) and caused death in 8 (21%) patients. Dementia was the only comorbidity more frequent in COVID-19 + patients (36% vs. 14%, p = 0.0013). However, in a multivariate analysis, institutionalization was the only variable associated with COVID-19 + (OR 17.0, 95% CI 5.0-60.0, p < 0.001). When considering severe COVID-19 (admission or death) vs. mild or absent COVID-19, institutionalization, neoplasm, dementia and a lower frequency of dopamine agonists were associated with severe COVID-19. In multivariate analysis, only institutionalization [OR 5.17, 95% CI 1.57-17, p = 0.004] and neoplasm [OR 8.0, 95%CI 1.27-49.8, p = 0.027] remained significantly associated. CONCLUSION: In our experience, institutionalization and oncologic comorbidity, rather than PD-related variables, increased the risk of developing COVID-19, and impacted on its severity. These findings suggest that epidemiologic factors and frailty are key factors for COVID-19 morbidity/mortality in PD. Appropriate preventive strategies should be implemented in institutionalized patients to prevent infection and improve prognosis.

[Clinical experience in the treatment of motor fluctuations in Parkinson's disease. Delphi consensus of a group of experts in movement disorders]. / Experiencia clínica en el tratamiento de las fluctuaciones motoras en la enfermedad de Parkinson. Consenso Delphi de un grupo de expertos en trastornos del movimiento.

INTRODUCTION: Motor fluctuations are one of the most common complications of Parkinson's disease and their treatment is still a complex matter. Therefore, from the Neurology Movement Disorders Group we present our clinical experience in the treatment of these complications, with the intention of it being useful in decision-making in daily clinical practice. DEVELOPMENT: Nineteen questions were developed based on a literature review and an open survey answered by members of this group. These issues were discussed in two phases, using the Delphi methodology. Considering the results of the survey, levodopa dose adjustment and dopamine agonists are the option with the best efficacy/tolerability ratio in the treatment of motor fluctuations. Rotigotine is useful in the motor fluctuations associated with gastroparesis, and intermittent subcutaneous apomorphine has positive effects in patients with unpredictable off periods. The most relevant adverse effect associated with dopamine agonists is impulse control disorder. Catechol-O-methyltransferase inhibitors are useful in the initial stages of motor fluctuations, especially in wearing off. Monoamine oxidase inhibitors are generally drugs that are well-tolerated and useful in motor fluctuations. If these measures are not effective, second-line treatments should be indicated on a case-by-case basis. CONCLUSION: The clinical profile of patients with Parkinson's disease is paramount in deciding the most appropriate therapy for the treatment of motor fluctuations.

TITLE: Experiencia clínica en el tratamiento de las fluctuaciones motoras en la enfermedad de Parkinson. Consenso Delphi de un grupo de expertos en trastornos del movimiento.Introducción. Las fluctuaciones motoras son una de las complicaciones más frecuentes en la enfermedad de Parkinson y su tratamiento sigue siendo complejo. Por ello, desde el Grupo de Trastornos del Movimiento de la Asociación Madrileña de Neurología presentamos nuestra experiencia clínica en el tratamiento de estas complicaciones, con la intención de que sea de utilidad en la toma de decisiones en la práctica clínica diaria. Desarrollo. Se elaboraron 19 preguntas a partir de una revisión bibliográfica y una encuesta abierta respondida por los miembros de dicho grupo. Dichas cuestiones se debatieron en dos fases, utilizando la metodología Delphi. Considerando los resultados de la encuesta, el ajuste de la dosis de levodopa y los agonistas dopaminérgicos son la opción con mejor relación eficacia/tolerabilidad en el tratamiento de las fluctuaciones motoras. La rotigotina es útil en las fluctuaciones motoras asociadas a gastroparesia, y la apomorfina subcutánea intermitente, en pacientes con off impredecible. El efecto adverso más relevante asociado a los agonistas dopaminérgicos es el trastorno del control de impulsos. Los inhibidores de la catecol-O-metiltransferasa son útiles en las fluctuaciones motoras de inicio, especialmente en el wearing off. Los inhibidores de la monoaminooxidasa son fármacos, en general, bien tolerados y útiles en las fluctuaciones motoras. En caso de que estas medidas no resulten eficaces, se deben indicar terapias de segunda línea de manera individualizada. Conclusión. El perfil clínico del paciente con enfermedad de Parkinson es primordial para decidir la terapia más adecuada en el tratamiento de las fluctuaciones motoras.

Non-motor symptom burden in patients with Parkinson's disease with impulse control disorders and compulsive behaviours: results from the COPPADIS cohort.

The study was aimed at analysing the frequency of impulse control disorders (ICDs) and compulsive behaviours (CBs) in patients with Parkinson's disease (PD) and in control subjects (CS) as well as the relationship between ICDs/CBs and motor, nonmotor features and dopaminergic treatment in PD patients. Data came from COPPADIS-2015, an observational, descriptive, nationwide (Spain) study. We used the validated Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS) for ICD/CB screening. The association between demographic data and ICDs/CBs was analyzed in both groups. In PD, this relationship was evaluated using clinical features and treatment-related data. As result, 613 PD patients (mean age 62.47 ± 9.09 years, 59.87% men) and 179 CS (mean age 60.84 ± 8.33 years, 47.48% men) were included. ICDs and CBs were more frequent in PD (ICDs 12.7% vs. 1.6%, p < 0.001; CBs 7.18% vs. 1.67%, p = 0.01). PD patients had more frequent previous ICDs history, premorbid impulsive personality and antidepressant treatment (p < 0.05) compared with CS. In PD, patients with ICDs/CBs presented younger age at disease onset, more frequent history of previous ICDs and premorbid personality (p < 0.05), as well as higher comorbidity with nonmotor symptoms, including depression and poor quality of life. Treatment with dopamine agonists increased the risk of ICDs/CBs, being dose dependent (p < 0.05). As conclusions, ICDs and CBs were more frequent in patients with PD than in CS. More nonmotor symptoms were present in patients with PD who had ICDs/CBs compared with those without. Dopamine agonists have a prominent effect on ICDs/CBs, which could be influenced by dose.

Acute-onset smell and taste disorders in the context of COVID-19: a pilot multicentre polymerase chain reaction based case-control study.

BACKGROUND AND PURPOSE: Specific respiratory tract infections, including COVID-19, may cause smell and/or taste disorders (STDs) with increased frequency. The aim was to determine whether new-onset STDs are more frequent amongst COVID-19 patients than influenza patients. METHOD: This was a case-control study including hospitalized patients of two tertiary care centres. Consecutive patients positive for COVID-19 polymerase chain reaction (cases) and patients positive for influenza polymerase chain reaction (historical control sample) were assessed during specific periods, employing a self-reported STD questionnaire. RESULTS: Seventy-nine cases and 40 controls were included. No significant differences were found in basal features between the two groups. New-onset STDs were significantly more frequent amongst cases (31, 39.2%) than in the control group (5, 12.5 %) [adjusted odds ratio 21.4 (2.77-165.4, P = 0.003)]. COVID-19 patients with new-onset STDs were significantly younger than COVID-19 patients without STDs (52.6 ± 17.2 vs. 67.4 ± 15.1, P < 0.001). Amongst COVID-19 patients who presented STDs, 22 (70.9%) recalled an acute onset and it was an initial manifestation in 11 (35.5%). Twenty-five (80.6%) presented smell disorders (mostly anosmia, 14, 45.2%) and 28 (90.3%) taste disorders (mostly ageusia, 14, 45.2%). Only four (12.9 %) reported concomitant nasal obstruction. The mean duration of STD was 7.5 ± 3.2 days and 12 patients (40%) manifested complete recovery after 7.4 ± 2.3 days of onset. CONCLUSION: New-onset STDs were significantly more frequent amongst COVID-19 patients than influenza patients; they usually had an acute onset and were commonly an initial manifestation. The use of STD assessment in anamnesis as a hint for COVID-19 and to support individuals' self-isolation in the current epidemic context is suggested.

Use of e-mail for Parkinson's disease consultations: Are answers just a clic away? / El correo electrónico en la consulta de Parkinson: ¿soluciones a un clic?

INTRODUCTION: The clinical problems of patients with movement disorders (MD) are complex, and the duration and frequency of face-to-face consultations may be insufficient to meet their needs. We analysed the implementation of an e-mail-based query service for our MD unit's patients and their primary care physicians (PCPs). METHODS: We retrospectively reviewed all consecutive emails sent and received over a period of 4 months, one year after implementation of the e-mail inquiry system. All patients received the during consultations, and PCPs, during scheduled informative meetings. We recorded and later analysed the profile of the questioner, patients' demographic and clinical data, number of queries, reason for consultation, and actions taken. RESULTS: From 1 January 2015 to 30 April 2015, the service received 137 emails from 63 patients (43% male, mean age 71±10.5) diagnosed with Parkinson's disease (76%), atypical parkinsonism (10%), and others (14%); 116 responses were sent. Twenty (32%) emails were written by patients, 38 (60%) by their caregivers, and 5 (8%) by their PCPs. The reasons for consultation were clinical in 50 cases (80%): 16 (32%) described clinical deterioration, 14 (28%) onset of new symptoms, and 20 (40%) side effects or concerns about medications. In 13 cases (20%), the query was bureaucratic: 11 were related to appointments (85%) and 2 were requests for clinical reports (15%). In response, new appointments were scheduled in 9 cases (14%), while the rest of the questions were answered by email. Patients were satisfied overall and the additional care burden on specialists was not excessive. CONCLUSIONS: Implementing an e-mail-based consultation system is feasible in MD units. It facilitates both communication between neurologists and patients and continued care in the primary care setting.

Reliability of the minimum basic dataset for diagnoses of cerebrovascular disease. / Fiabilidad del conjunto mínimo básico de datos en el diagnóstico de la enfermedad cerebrovascular.

INTRODUCTION: The minimum basic dataset is the largest available hospital care administrative database that is used in clinical studies and hospital management in association with diagnosis-related groups (DRGs). In 2011, the quality of the national MBDS in hospital discharges was audited, in order to assess its reliability. This paper presents a sub-analysis of the results from that analysis which are referred to cerebrovascular disease (CVD). METHODS: Using all discharge reports from the Spanish MBDS in 2009, a representative sample was obtained by stratified sampling and 11 209 records were evaluated. Outcome indicators were obtained to measure any differences observed between the national MBDS being evaluated and the hospital's original MBDS. Analysis of codes for CVD as a primary diagnosis was performed for ICD-9-CM diagnostic categories 430 through 438. We evaluated error rates in the selection and classification of main diagnoses, as well as in DRG assignment. RESULTS: There were 397 discharges of cases of CVD which included 21 different DRGs. Diagnostic coding showed a concordance rate of 81.87%; the selection error rate was 2.26% and the classification error rate was 15.87%. The error rate in the DRG was 16.12% and associated with the greatest impact on the mortality risk level. CONCLUSIONS: While the errors we observed must be taken into account, data suggest that the quality of the MBDS for CVD is sufficient to ensure delivery of valid information. The hospital discharge registry serves as a valuable tool for use in studies of this disease.

The syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis mimicking an acute stroke.

BACKGROUND AND PURPOSE: The syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL) can present as sudden onset of focal neurological deficits which are clinically and radiologically indistinguishable from an ischaemic stroke. Its diagnosis requires a lumbar puncture (LP), which contraindicates intravenous thrombolytic therapy (IV-tPA). METHODS: All patients referred to our stroke centre as a stroke code resulting in a final diagnosis of HaNDL syndrome from June 2005 to June 2015 were retrospectively analysed. RESULTS: Nine cases were identified: seven women and two men (mean age 27.6 years, range 15-51). Clinical onset consisted of isolated aphasia (two) and aphasia with right hemiparesis/hemiparaesthesia (seven). All patients had headache in the acute setting, lasting 2-12 h. Cranial computed tomography (CT) and CT angiography (CTA) were normal in all patients. Perfusion CT was performed in seven patients, showing left hemispheric focal hypoperfusion in five cases; the remaining two were normal. Five patients were initially diagnosed as stroke and treated uneventfully with IV-tPA. Cranial magnetic resonance imaging within 48 h was normal in all cases. LP performed in all patients showed pleocytosis (range 17-351 cells/mm(3) ), high protein levels (range 0.4-1.6 g/l) and normal glucose levels. All cases recovered within 12 h and suffered a second episode within 72 h. Patients were asymptomatic between episodes and after remission. CONCLUSIONS: The decision to thrombolyse or perform an LP in HaNDL patients mimicking a stroke is difficult in the acute setting. Perfusion CT can provide misleading results and CTA may be useful in ruling out occlusion of a cerebral vessel.

Central nervous system involvement in adult patients with invasive infection caused by Streptococcus agalactiae.

INTRODUCTION: Streptococcus agalactiae is frequently an asymptomatic coloniser and a cause of neonatal and puerperal sepsis. Infections in nonpregnant adults are uncommon. The frequency of neurological complications caused by invasive infection with this microorganism in adults remains unknown. Here, we study the frequency and characteristics of central nervous system (CNS) involvement in adults with invasive S. agalactiae infection. PATIENTS AND METHODS: Review of all adults with invasive S. agalactiae infection between 2003 and 2011 in a tertiary hospital. RESULTS: S. agalactiae was isolated from blood, CSF or synovial fluid in 75 patients. Among them, 7 (9,3%) displayed neurological involvement: 5 men and 2 nonpregnant women, aged between 20 and 62 years. Diagnoses were spinal epidural abscess due to spondylodiscitis with spinal cord compression; acute bacterial meningitis; ischemic stroke as presentation of bacterial endocarditis (2 patients each); and meningoventriculitis after neurosurgery and ventricular shunting. One patient with endocarditis caused by S. agalactiae and S. aureus died in the acute phase, and another died 3 months later from metastatic cancer. The other patients recovered without sequelae. All patients had systemic predisposing factors for infection and 5 (71,4%) had experienced disruption of the mucocutaneous barrier as a possible origin of the infection. CONCLUSIONS: CNS involvement is not uncommon in adult patients with invasive infection caused by S. agalactiae. Isolating S. agalactiae, especially in cases of meningitis, should lead doctors to search for predisposing systemic disease and causes of mucocutaneous barrier disruption.

Dopaminergic agonists in Parkinson's disease.

BACKGROUND: Non-ergoline dopamine agonists (DA) are effective treatments for Parkinson's disease (PD). This review presents the pharmacology, evidence of efficacy and safety profile of pramipexole, ropinirole, and rotigotine, and practical recommendations are given regarding their use in clinical practice. RESULTS: Extended-release formulations of pramipexole and ropinirole and transdermal continuous delivery rotigotine patches are currently available; these may contribute to stabilising of plasma levels. In early PD, the three drugs significantly improve disability scales, delay time to dyskinesia and allow a later introduction of levodopa. In late PD they reduced total 'off'-time, improved Unified Parkinson's Disease Rating Scale (UPDRS) in both 'on' and 'off' state and allowed a reduction in total levodopa dosage. A significant improvement in quality of life scales has also been demonstrated. Extended-release formulations have proved to be non-inferior to the immediate release formulations and are better tolerated (ropinirole). Despite a generally good safety profile, serious adverse events, such as impulse control disorder and sleep attacks, need to be routinely monitored. Although combination therapy has not been addressed in scientific literature, certain combinations, such as apomorphine and another DA, may be helpful. Switching from one DA to another is feasible and safe, although in the first days an overlap of dopaminergic side effects may occur. When treatment with DA is stopped abruptly, dopamine withdrawal syndrome may present. Suspending any DA, especially pramipexole, has been linked to onset of apathy, which may be severe. CONCLUSIONS: New non-ergotine DAs are a valuable option for the treatment of both early and late PD. Despite their good safety profile, serious adverse effects may appear; these effects may have a pathoplastic effect on the course of PD and need to be monitored.

Off-label intravenous thrombolysis in acute stroke.

BACKGROUND AND PURPOSE: Therapy for stroke with intravenous tissue plasminogen activator (IV-tPA) is hampered by tight licensing restrictions; some of them have been discussed in recent literature. We assessed the safety and effectiveness of off-label IV-tPA in the clinical settings. METHODS: Retrospective analysis of all the patients treated with IV-tPA at our Stroke Unit. Patients were divided into two groups by licence criteria [on-label group (OnLG), off-label group (OffLG)]. Primary outcome measures were symptomatic intracranial haemorrhages (sICH), major systemic haemorrhages, modified Rankin scale (mRS) and mortality rate at 3months. RESULTS: Five hundred and five patients were registered, 269 (53.2%) were assigned to OnLG and 236 (46.9%) to OffLG. Inclusion criteria for the OffLG were aged >80 years (129 patients), time from onset of symptoms to treatment over 3h (111), prior oral anticoagulant treatment with International Normalised Ratio≤1.7 (41), combination of previous stroke and diabetes mellitus (14), surgery or severe trauma within 3months of stroke (13), National Institutes of Health Stroke Scale score over 25 (11), intracranial tumours (5), systemic diseases with risk of bleeding (7) and seizure at the onset of stroke (2). No significant differences were identified between both groups regarding the proportion of sICH (OnLG 2.2% vs. OffLG 1.6%, P=0.78) or the 3-month mortality rate (11.1% vs. 19%: odds ratio (OR), 1.49; 95% CI, 0.86-2.55; P=0.14). Multivariate analysis showed no significant differences in functional independence at 3months between both groups (mRS <3 64.3% vs. 50.4%: OR mRS >2 1.7; 95% CI, 0.96-2.5; P=0.07). CONCLUSION: Intravenous thrombolysis may be safe and efficacious beyond its current label restrictions.
