Effectiveness and safety of safinamide in the Toledo Movement Disorders Unit. / Efectividad y seguridad de la safinamida en la Unidad de Trastornos de Movimiento de Toledo.

INTRODUCTION: The management of motor fluctuations in Parkinson's disease (PD) can be challenging, and current therapeutic options include the use of monoamine oxidase B inhibitors (MAO-B inhibitors), among others. The aim of this study was to evaluate the effectiveness and safety of safinamide in the clinical practice carried out in the Toledo Movement Disorders Unit. PATIENTS AND METHODS: This is a retrospective study in which data were collected at baseline and at six months from PD patients who were started on safinamide as an add-on therapy with a stable dose of levodopa in line with standard clinical practice. An analysis was performed by subgroups: patients who were given low-dose safinamide and patients who previously received rasagiline. RESULTS: Ninety patients (47 previously received rasagiline) completed the six-month follow-up. A statistically significant decrease in morning akinesia, nocturnal akinesia, wearing off, unpredictable off phenomenon and Unified Parkinson's Disease Rating Scale-III was observed both in those who previously received rasagiline and in those treated with low doses of safinamide. No variation was found in the dyskinesias. The adverse events described were mild, with generalised weakness, dizziness, nausea, headache and alopecia. CONCLUSIONS: Safinamide has been shown to be effective and safe in improving motor fluctuations, motor symptoms and the subjective perception of disease severity in PD patients previously receiving rasagiline and in those receiving low-dose safinamide, all of which is accompanied by a good safety profile.

No hubo variación en las discinesias. Los acontecimientos adversos descritos fueron leves, y se describieron sensación de debilidad generalizada, mareo, náuseas, cefalea y alopecia. Conclusiones. La safinamida ha demostrado ser eficaz y segura en la mejoría de fluctuaciones motoras, los síntomas motores y la percepción subjetiva de la gravedad de la enfermedad tanto en pacientes con EP que recibieron previamente rasagilina como en los que recibieron safinamida en dosis bajas, todo ello acompañado de un buen perfil de seguridad.

Clinical utility of a personalized and long-term monitoring device for Parkinson's disease in a real clinical practice setting: An expert opinion survey on STAT-ON™.

BACKGROUND: STAT-ON™ is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient at every moment of the day in normal life. Our aim was to analyze the opinion of different Parkinson's disease experts about the STAT-ON™ tool after using the device in a real clinical practice setting (RCPS). METHODS: STAT-ON™ was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. Each neurologist had the device for at least three months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. RESULTS: Two thirds of neurologists (53.8% females; mean age 44.9±9 years old) worked in a Movement Disorders Unit, the average experience in PD was 16±6.9 years, and 40.7% of them had previously used other devices. A total of 119 evaluations were performed in 114 patients (range 2-9 by neurologist; mean 4.5±2.3). STAT-ON™ was considered "quite" to "very useful" by 74% of the neurologists with an overall opinion of 6.9±1.7 (0, worst; 10, best). STAT-ON™ was considered better than diaries by 70.3% of neurologists and a useful tool for the identification of patients with advanced PD by 81.5%. Proper identification of freezing of gait episodes and falls were frequent limitations reported. CONCLUSION: STAT-ON™ could be a useful device for using in PD patients in clinical practice.

[Opicapone for the treatment of Parkinson's disease: real-life data in Spain]. / Opicapona para el tratamiento de la enfermedad de Parkinson: datos de vida real en España.

Opicapone is a catechol-O-methyl-transferase (iCOMT) inhibitor authorized in Europe in 2016 and indicated as adjunctive therapy to preparations of levodopa/ DOPA decarboxylase inhibitors in adult patients with Parkinson's disease and end-of-dose motor fluctuations who cannot be stabilised on those combinations. The efficacy of opicapone in these patients has been demonstrated in two pivotal randomized clinical trials, BIPARK I and BIPARK II, in which it has demonstrated its superiority versus placebo and non-inferiority versus entacapone. Although they constitute the gold standard for the evaluation of interventions, randomized clinical trials present limitations of external validity due to the use of strict eligibility criteria. Therefore, it is considered necessary to have a more comprehensive evaluation of the efficacy of the drug, complementing the information obtained from randomized clinical trials with that of "real world or real clinical practice" studies. The objective of this review has been to collect and put into perspective the information available on opicapone coming from real clinical practice studies in Spain. The data from Spain with opicapone in 18 series with more than 1,000 patients in total, confirm the safety and efficacy previously reported with this iCOMT. Furthermore, they show that opicapone is especially useful in patients with a less advanced stage of the disease and mild motor fluctuations, which would suggest that the earlier its introduction in the therapeutic scheme for the management of motor fluctuations, the better is the benefit-risk ratio for the drug.

La opicapona es un inhibidor de la catecol-O-metiltransferasa (iCOMT) autorizado en Europa en 2016 como terapia adyuvante a las preparaciones de levodopa/inhibidores de la dopa descarboxilasa en pacientes adultos con enfermedad de Parkinson y fluctuaciones motoras de final de dosis que no puedan ser estabilizados con esas combinaciones. La eficacia de la opicapona en estos pacientes ha sido demostrada en dos ensayos clínicos pivotales, BIPARK I y BIPARK II, en los que se ha demostrado la superioridad frente al placebo y la no inferioridad frente a la entacapona. A pesar de que constituyen el estándar para la evaluación de intervenciones, los ensayos clínicos aleatorizados presentan limitaciones de validez externa debidas a la utilización de criterios estrictos de elegibilidad. Por tanto, se considera necesario disponer de una evaluación más amplia de la eficacia general del fármaco, complementando la información de los ensayos clínicos aleatorizados con estudios de 'vida real o práctica clínica real'. El objetivo de esta revisión ha sido recopilar y poner en perspectiva la información disponible sobre los resultados de la opicapona en estudios de práctica clínica real en España. Los datos acumulados en España con opicapona en 18 series con más de 1.000 pacientes confirman la seguridad y la eficacia de este iCOMT comunicadas previamente. Además, muestran que la opicapona es especialmente útil en pacientes en un estadio de la enfermedad menos avanzado y fluctuaciones motores leves, lo que sugeriría una mejor relación beneficio-riesgo cuanto más temprana sea su introducción en el esquema terapéutico para el tratamiento de las fluctuaciones motoras.

Staging Parkinson's Disease Combining Motor and Nonmotor Symptoms Correlates with Disability and Quality of Life.

INTRODUCTION: In a degenerative disorder such as Parkinson's disease (PD), it is important to establish clinical stages that allow to know the course of the disease. Our aim was to analyze whether a scale combining Hoehn and Yahr's motor stage (H&Y) and the nonmotor symptoms burden (NMSB) (assessed by the nonmotor symptoms scale (NMSS)) provides information about the disability and the patient's quality of life (QoL) with regard to a defined clinical stage. MATERIALS AND METHODS: Cross-sectional study in which 603 PD patients from the COPPADIS cohort were classified according to H&Y (1, stage I; 2, stage II; 3, stage III; 4, stage IV/V) and NMSB (A: NMSS = 0-20; B: NMSS = 21-40; C: NMSS = 41-70; D: NMSS ≥ 71) in 16 stages (HY.NMSB, from 1A to 4D). QoL was assessed with the PDQ-39SI, PQ-10, and EUROHIS-QOL8 and disability with the Schwab&England ADL (Activities of Daily Living) scale. RESULTS: A worse QoL and greater disability were observed at a higher stage of H&Y and NMSB (p < 0.0001). Combining both (HY.NMSB), patients in stages 1C and 1D and 2C and 2D had significantly worse QoL and/or less autonomy for ADL than those in stages 2A and 2B and 3A and 3B, respectively (p < 0.005; e.g., PDQ-39SI in 1D [n = 15] vs 2A [n = 101]: 28.6 ± 17.1 vs 7.9 ± 5.8; p < 0.0001). CONCLUSION: The HY.NMSB scale is simple and reflects the degree of patient involvement more accurately than the H&Y. Patients with a lower H&Y stage may be more affected if they have a greater NMS burden.

Depression is Associated with Impulse-compulsive Behaviors in Parkinson's disease.

BACKGROUND: Depression and impulse control disorders (ICDs) are both common in Parkinson's disease (PD) patients and their coexistence is frequent. Our aim was to determine the relationship between depression and impulsive-compulsive behaviors (ICBs) in a large cohort of PD patients. METHODS: PD patients recruited from 35 centers of Spain from the COPPADIS cohort from January 2016 to November 2017 were included in the study. The QUIP-RS (Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale) was used for screening ICDs (cutoff points: gambling ≥6, buying ≥8, sex≥8, eating≥7) and compulsive behaviors (CBs) (cutoff points: hobbyism-punding ≥7). Mood was assessed with the BDI-II (Beck Depression Inventory - II) and major, minor, and subthreshold depression were defined. RESULTS: Depression was more frequent in PD patients with ICBs than in those without: 66.3% (69/104) vs 47.5% (242/509); p<0.0001. Major depression was more frequent in this group as well: 22.1% [23/104] vs 14.5% [74/509]; p=0.041. Considering types of ICBs individually, depression was more frequent in patients with pathological gambling (88.9% [8/9] vs 50.2% [303/603]; p=0.021), compulsive eating behavior (65.9% [27/41] vs 49.7% [284/572]; p=0.032), and hobbyism-punding (69% [29/42] vs 49.4% [282/571]; p=0.010) than in those without, respectively. The presence of ICBs was also associated with depression (OR=1.831; 95%CI 1.048-3.201; p=0.034) after adjusting for age, sex, civil status, disease duration, equivalent daily levodopa dose, antidepressant treatment, Hoehn&Yahr stage, non-motor symptoms burden, autonomy for activities of daily living, and global perception of QoL. LIMITATIONS: Cross-sectional design. CONCLUSIONS: Depression is associated with ICBs in PD. Specifically, with pathological gambling, compulsive eating behavior, and hobbyism-punding.

Mood in Parkinson's disease: From early- to late-stage disease.

BACKGROUND: Although depression is known to be frequent in Parkinson's disease (PD), it is unclear how mood can change and/or impact on patient's quality of life (QoL) over time. Our aim was to analyze the frequency of depression, mood related factors and the contribution of mood to a patient's QoL perception in regard to disease duration. METHODS: PD patients recruited from the COPPADIS cohort from January 2016 to November 2017 were included in this cross-sectional study. Three groups were defined: <5 years (Group A); from 5 to <10 years (Group B); ≥10 years (Group C). Analysis with well-planned linear regression models was conducted to determine how different factors contribute to mood (Beck Depression Inventory-II [BDI-II] as dependent variable), to health-related QoL (39-item Parkinson's Disease Questionnaire [PDQ-39SI] as dependent variable) and to global QoL (European Health Interview Survey - Quality of Life Eight-Item Index [EUROHIS-QOL8] as dependent variable). RESULTS: Six hundred and sixty-three PD patients (62.6 ± 8.9 years old, 59.6% males) were included: Group A, 50.1% (n = 332); Group B, 33.3% (n = 221) and Group C, 16.6% (n = 110). There were no differences between the three groups in terms of the frequency of depressive symptoms nor the frequency of depression type (major vs. minor vs. subthreshold) (p = 0.729). However, the unique percent variance of PDQ-39SI and EUROHIS-QOL8 explained by BDI-II total score was 2 (23.7%) and threefold (26.9%), respectively, in Group C compared to the other two groups. EUROHIS-QOL8 total score provided the highest unique contribution to mood (16.8%). CONCLUSIONS: Although depression-type frequency does not appear to change over time in PD; the contribution of mood on QoL perception is greater in patients with longer disease duration.

Clinical utility of a personalized and long-term monitoring device for Parkinson's disease in a real clinical practice setting: An expert opinion survey on STAT-ON™.

BACKGROUND: STAT-ON™ is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient at every moment of the day in normal life. Our aim was to analyze the opinion of different Parkinson's disease experts about the STAT-ON™ tool after using the device in a real clinical practice setting (RCPS). METHODS: STAT-ON™ was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. Each neurologist had the device for at least three months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. RESULTS: Two thirds of neurologists (53.8% females; mean age 44.9±9 years old) worked in a Movement Disorders Unit, the average experience in PD was 16±6.9 years, and 40.7% of them had previously used other devices. A total of 119 evaluations were performed in 114 patients (range 2-9 by neurologist; mean 4.5±2.3). STAT-ON™ was considered "quite" to "very useful" by 74% of the neurologists with an overall opinion of 6.9±1.7 (0, worst; 10, best). STAT-ON™ was considered better than diaries by 70.3% of neurologists and a useful tool for the identification of patients with advanced PD by 81.5%. Proper identification of freezing of gait episodes and falls were frequent limitations reported. CONCLUSION: STAT-ON™ could be a useful device for using in PD patients in clinical practice.

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.

Quality of life and non-motor symptoms in Parkinson's disease patients with subthreshold depression.

BACKGROUND: The role of subthreshold depression (subD) in Parkinson's Disease (PD) is not clear. The present study aimed to compare the quality of life (QoL) in PD patients with subD vs patients with no depressive disorder (nonD). Factors related to subD were identified. MATERIAL AND METHODS: PD patients and controls recruited from the COPPADIS cohort were included. SubD was defined as Judd criteria. The 39-item Parkinson's disease Questionnaire (PDQ-39) and the EUROHIS-QOL 8-item index (EUROHIS-QOL8) were used to assess QoL. RESULTS: The frequency of depressive symptoms was higher in PD patients (n = 694) than in controls (n = 207) (p < 0.0001): major depression, 16.1% vs 7.8%; minor depression, 16.7% vs 7.3%; subD, 17.4% vs 5.8%. Both health-related QoL (PDQ-39; 18.1 ±â€¯12.8 vs 11.6 ±â€¯10; p < 0.0001) and global QoL (EUROHIS-QOL8; 3.7 ±â€¯0.5 vs 4 ±â€¯0.5; p < 0.0001) were significantly worse in subD (n = 120) than nonD (n = 348) PD patients. Non-motor Symptoms Scale (NMSS) total score was higher in subD patients (45.9 ±â€¯32 vs 29.1 ±â€¯25.8;p < 0.0001). Non-motor symptoms burden (NMSS;OR = 1.019;95%CI 1.011-1.028; p < 0.0001), neuropsychiatric symptoms (NPI; OR = 1.091; 95%CI 1.045-1.139; p < 0.0001), impulse control behaviors (QUIP-RS; OR = 1.035; 95%CI 1.007-1063; p = 0.013), quality of sleep (PDSS; OR = 0.991; 95%CI 0.983-0.999; p = 0.042), and fatigue (VAFS-physical; OR = 1.185; 95%CI 1.086-1.293; p < 0.0001; VAFS-mental; OR = 1.164; 95%CI 1.058-1.280; p = 0.0001) were related to subD after adjustment to age, disease duration, daily equivalent levodopa dose, motor status (UPDRS-III), and living alone. CONCLUSIONS: SubD is a frequent problem in patients with PD and is more prevalent in these patients than in controls. QoL is worse and non-motor symptoms burden is greater in subD PD patients.

COPPADIS-2015 (COhort of Patients with PArkinson's DIsease in Spain, 2015): an ongoing global Parkinson's disease project about disease progression with more than 1000 subjects included. Results from the baseline evaluation.

BACKGROUND AND PURPOSE: In Parkinson's disease (PD), the course of the disorder is highly variable between patients. Well-designed, prospective studies for identifying PD progression biomarkers are necessary. Our aim was to show the results of baseline evaluations of an ongoing global PD project, COPPADIS-2015 (Cohort of Patients with PArkinson's DIsease in Spain, 2015). METHODS: This was an observational, descriptive, nationwide study (Spain). The recruitment period ended in October 2017. Baseline evaluation included more than 15 validated scales and complementary studies in a subgroup of participants. RESULTS: In total, 1174 subjects from 35 centres were considered valid for baseline analysis: 694 patients (62.6 ± 8.9 years old, 60.3% males), 273 caregivers (58.5 ± 11.9 years old, 31.8% males) and 207 controls (61 ± 8.3 years old, 49.5% males). The mean disease duration was 5.5 ± 4.4 years. Hoehn and Yahr stage was 1 or 2 in 90.7% of the patients whilst 33.9% and 18.1% of them presented motor fluctuations and dyskinesias, respectively. The mean Non-Motor Symptoms Scale total score was 45.4 ± 38.1, and 30.4% of the patients presented cognitive impairment, 16.1% major depression, 12.7% impulse control disorder, 7.2% compulsive behaviour, 57.2% pain and 13.2% falls. Compared to the control group, PD patients presented a significantly higher burden of non-motor symptoms and a worse quality of life. More than 300 subjects conducted complementary studies (serum biomarkers, genetic and neuroimaging). CONCLUSIONS: Parkinson's disease is a complex disorder and different non-motor symptoms are frequently present and are more prevalent than in controls. In real clinical practice it is important to ask for them.

Paquimeningitis hipertrófica autoinmune. Una entidad a tener en cuenta en la población pediátrica / Autoimmune hypertrophic pachymeningitis. A disease to consider in childhood

Introducción: La paquimeningitis hipertrófica es un proceso poco frecuente en la población general, y mucho menos aún en la población pediátrica. Actualmente se está estudiando una posible base inmunológica, con las consiguientes implicaciones en su tratamiento. Caso clínico: Se expone el caso de una paciente de 13 años de edad, con cefalea y afectación de los pares craneales con dicho diagnóstico, establecido mediante pruebas de imagen, y coexistencia de anticuerpos antineutrófilo citoplasmático con patrón mieloperoxidasa, con todo el estudio de extensión negativo. Conclusión: El diagnóstico de dicha patología y su relación con la etiología autoinmune, aunque es poco frecuente, debe considerarse, ya que las implicaciones en cuanto al tratamiento, pronóstico y evolución son muy importantes

Introduction: Hypertrophic pachymeningitis is an uncommon process in the population at large, and even less common among the paediatric population. A possible immunological basis is currently being studied, with the consequent implications for its treatment. Clinical case study: The case described is that of a 13 year-old patient with headache and affected cranial nerves with the said diagnosis, reached through imaging tests and the coexistence of cytoplasmic anti-neutrophil antibodies with a myeloperoxidase pattern, with the extension study entirely negative. Conclusion: Diagnosis of the said pathology and its link with autoimmune aetiology, while infrequent, must be taken into consideration, as the implications for treatment, prognosis and development are considerable

Dopamine-dependent changes of cortical excitability induced by transcranial static magnetic field stimulation in Parkinson's disease.

Transcranial static magnetic field stimulation (tSMS) is a recent low-cost non-invasive brain stimulation technique that decreases cortical excitability in healthy subjects. The objective of the present study was to test the ability of tSMS to modulate cortical excitability in patients with Parkinson's disease. We performed a randomized double-blind sham-controlled cross-over study to assess cortical excitability before and immediately after tSMS (or sham) applied for 10 min to the more affected motor cortex of patients with Parkinson's disease. Cortical excitability was quantified by the amplitude of motor evoked potentials (MEPs) elicited by single-pulse transcranial magnetic stimulation (TMS). tSMS significantly decreased MEP amplitudes in patients OFF medication (after overnight withdrawal of dopaminergic drugs), but not ON medication (after an acute dose of levodopa). The between-patients variability of tSMS-induced changes was significantly greater ON medication. The variability ON medication could be partly explained by disease progression, i.e. the more advanced the patient, the more likely it was to observe a switch from inhibitory tSMS plasticity OFF medication to paradoxical facilitatory plasticity ON medication. These results suggest that tSMS induces dopamine-dependent changes of cortical excitability in patients with Parkinson's disease.

Encefalopatía subaguda con respuesta a esteroides sin evidencia de enfermedad autoinmune tiroidea: un caso de meningoencefalitis autoinmune no vasculítica / Sub-acute encephalopathy that responds to sterorids without any evidence of autoinmune thyroid disease a case of non-vasculitic autoimmune nm

Aim. To report a case of sub-acute encephalopathy with all the extension study negative and with response to steroid therapy. Case report. The study involves a 22-year-old female with no relevant past history who presented symptoms of sub-acute encephalopathy consisting in behavioural disorders, generalised seizures and bradypsychia, which gradually progressed to a state of low-level consciousness. While she was in hospital all kinds of diagnostic tests were conducted, the results of which were either normal or negative; the electroencephalogram was repeatedly abnormal and detection of protein 14-3-3 in cerebrospinal fluid was positive. Empirical corticoid therapy was begun with clinical and electrophysiological improvements and the patient recovered completely without any sequelae. Conclusions. With no evidence of autoimmune thyroid disease, although non-specific autoimmunity was present, the patient was diagnosed as having non-vasculitic autoimmune meningoencephalitis (AU)

Objetivo. Presentar un caso de encefalopatía subaguda con todo el estudio de extensión negativo y con respuesta a terapia esteroidea. Caso clínico. Mujer de 22 años sin antecedentes de interés que presentó un cuadro de encefalopatía subaguda consistente en alteraciones del comportamiento, crisis generalizadas y bradipsiquia, que evolucionó progresivamente a un estado de bajo nivel de conciencia. Durante su ingreso se realizaron todo tipo de pruebas diagnósticas, que fueron normales o negativas; el electroencefalograma fue repetidamente anormal y se detectó positividad de la proteína 14-3-3 en el líquido cefalorraquídeo. Se inició corticoterapia empírica con mejoría clínica y electrofisiológica, y recuperación ad integrum sin secuelas. Conclusiones. Sin la evidencia de enfermedad autoinmune tiroidea, aunque con presencia de autoinmunidad no específica, se diagnosticó a la paciente meningoencefalitis autoinmune no vasculítica (AU)

Mielitis transversa aguda tras anestesia epidural obstétrica / Acute transverse myelitis after obstetric epidural anesthesia

Introducción. La mielitis transversa aguda es una disfunciónmedular aguda o subaguda con afectación motora,sensitiva y/o esfinteriana secundaria que puede deberse amúltiples causas. Caso clínico. Presentamos a una paciente de 32 años concuadro agudo de disfunción vesical y fiebre, seguido de pérdidade fuerza y alteración sensitiva en miembros inferiores, con nivelsensitivo medular dorsal D2-D3 a las 2 semanas de un partoeutócico a término con anestesia epidural no complicada. El líquidocefalorraquídeo (LCR) mostraba pleocitosis linfocitarialeve, hiperproteinorraquia con glucorraquia normal, ausenciade bandas oligoclonales y estudios virológicos en suero y LCRnegativos. La resonancia magnética cervicodorsal mostraba ensanchamientodel cordón medular con hiperintensidad difusa anivel C6-D1 y D2-D5 sin captación de contraste. Tras tratamientocon metilprednisolona, la evolución fue favorable, estandocompletamente asintomática al año y sin nuevos episodiosde disfunción neurológica tras 2 años de seguimiento. Discusión. Tras descartar con los estudios complementarioslas causas más frecuentes de mielopatía aguda nocompresiva, como esclerosis múltiple, enfermedades sistémicas,infarto medular o infecciones, se considera que lapaciente ha presentado una mielitis transversa aguda parainfecciosaen la que la anestesia epidural sería incidental,pero posiblemente un factor contribuyente

Introduction. Acute transverse myelitis is an acuteor subacute disorder of the spinal cord resulting in motor, sensory and sphincter dysfunction secondary to variouscauses.Case report. We present a 32 year-old female patientwith an acute episode of bladder dysfunction andfever, followed by motor and sensory dysfunction in legswith sensory spinal level at D2-D3, two weeks after aneutocic delivery with uncomplicated epidural anesthesia.The cerebrospinal fluid (CSF) showed mild lymphocyticpleocytosis, high protein levels with normal glucose concentration,absence of oligoclonal bands and negativeserum and CSF virology screening. The cervicodorsalmagnetic resonance imaging showed widening of thespinal cord with diffuse patchy hyperintensity on theC6-D1 and D2-D5 levels without contrast enhancement.The patient was treated with intravenous high doses ofmethylprednisolone with favorable outcome and completerecovery within one year and no relapses two yearsafter the episode.Discussion. The main etiologies of non-compressiveacute myelopathy as multiple sclerosis, systemic diseases,spinal cord infarct and direct infections have beenruled out with the complementary examinations. Weconsider that our patient had a parainfectious acutetransverse myelitis and epidural anesthesia could be anincidental but possible contributing factor
