Levodopa infusion improves impulsivity and dopamine dysregulation syndrome in Parkinson's disease.

BACKGROUND: Impulsivity and dopamine dysregulation syndrome are frequent complications of treatment in Parkinson's disease (PD). METHODS: We assessed the effect of jejunal levodopa infusion (JLI) on behavioral symptoms in 8 PD patients with motor complications and severe impulsivity and dopamine dysregulation syndrome (DDS), which had not be controlled before by adjusting oral medications. The infusion was delivered during 15 hours (daily dose 1007.2 ± 302.5 mg) and stopped at night time. Patients were reassessed after 25 ± 9 weeks of treatment with a stable dose of jejunal l-dopa. RESULTS: Off periods and dyskinesias decreased by 27% and 20,7% respectively, compared to baseline. DDS and all types of impulse control disorders (ICDs) improved in all patients, with nearly complete symptom resolution. Punding improved in all 5 patients but disappeared completely in only 1. CONCLUSIONS: Our experience suggests that l-dopa infusion has a positive effect on both motor complications and behavioral disorders. This treatment approach deserves further controlled studies.

Neurobehçet: a propósito de un caso / NeuroBehçet: a case

La enfermedad de Behçet es un trastorno inflamatorio sistémico, caracterizado por aftosis orogenital así como por alteraciones oftalmológicas y cutáneas. Un 5% de los pacientes presenta manifestaciones neurológicas. Se presenta un caso de neurobehçet con participación neurológica inhabitual.Varón de 28 años con antecedente de aftas orales y genitales recurrentes e historia de foliculitis, que acudió por cuadro de 48 h de fiebre, cefalea, náuseas, paresia del sexto par craneal y del miembro superior derecho. El análisis del líquido cefalorraquídeo reveló pleocitosis linfocitaria con hiperproteinorraquia, se inició tratamiento antibiótico de amplio espectro. Se realizó resonancia magnética cerebral, que mostró lesiones hiperintensas de predominio troncoencefálico con realce tras infusión de gadolinio y trombosis del seno transverso izquierdo. El paciente mejoró progresivamente con tratamiento intravenoso con corticoides hasta quedar asintomático.La afectación neurológica en la enfermedad de Behçet es infrecuente y más aún la coexistencia de lesiones intraparenquimatosas y extraparenquimatosas. Habitualmente, presenta buena respuesta al tratamiento inmunosupresor (AU)

Behçet′s disease is an inflammatory systemic disorder, with oral and genital ulcers, as well as ophthalmologic and cutaneous disturbances. 5% of the patients have neurological alterations. We present a case of neuroBehçet with a rare neurological involvement.A 28 years-old male patient with recurrent oral and genital ulcer history and folliculitis presents 48h progressive fever, headache, nausea, right sixth cranial nerve palsy and right upper limb paresis. The CSF showed lymphocyte pleocytosis and high proteinorrachia, so antibiotic treatment was initiated. Cerebral MR found hyperintense enhancing lesions in the brainstem and left transverse sinus thrombosis. Patient improved with endovenous corticosteroids and was discharged asymptomatic.Neurological involvement in Behçet′s disease is rare and moreover the coexistence of parenchymatous and non-parenchymatous alterations in the same patient. It normally has a good response to immunosuppressant treatment (AU)

Ateromatosis del arco aórtico y riesgo de ictus isquémico: a propósito de un caso / Atheroma of the aortic arch and risk of ischemic stroke: a case

Las placas de ateroma del arco aórtico son un factor de riesgo poco conocido de ictus isquémico, generalmente por la producción de embolias arterioarteriales. Presentamos el caso de un varón de 67 años que llegó a nuestro hospital con un ictus hemisférico izquierdo con estudio etiológico rutinario negativo. En el ecocardiograma transesofágico (ETE), se detectó una gran placa de ateroma en arco aórtico, ulcerada y complicada, con trombo móvil en su pared, presuntamente causante del cuadro actual. La ateromatosis del arco aórtico es un factor de riesgo independiente de infarto cerebral, especialmente las placas grandes, ulceradas o trombosadas, y aparece en un porcentaje elevado de pacientes con ictus criptogénico. La actitud diagnóstica y terapéutica es controvertida en estos casos, pero se suele aconsejar el ETE, como método de referencia diagnóstico, y la antiagregación, como prevención secundaria. En el momento actual, son necesarios más estudios epidemiológicos, así como ensayos clínicos, para elaborar guías de tratamiento en estas situaciones (AU)

Aortic arch atheroma is a poorly understood risk factor for stroke, usually producing arterial embolisms. A 67 year-old male was admitted to our hospital with a left hemispheric stroke with a negative routine aetiological study. Transesophageal echocardiography (TEE) showed atherosclerosis of the aortic arch with mobile thrombus, presumably causing the actual stroke. Aortic arch atheromatosis is an independent risk factor for cerebral infarction, particularly large, ulcerated or thrombotic plaques, and it is found in many patients with cryptogenic stroke. Diagnosis and treatmnent is not clear in these cases, but TEE is used as gold-standard complementary test with antiplatelets as secondary prevention. Further epidemiological studies and clinical trials are necessary for the preparation of clinical guides (AU)
