RESUMO
RESUMEN INTRODUCCIÓN: El parkinsonismo es un síndrome clínico, caracterizado por temblor, rigidez y bradicinesia, debido a la alteración en el circuito dopaminérgico ganglio-basal, específicamente a nivel nigroestriatal. A continuación se presenta un caso de parkinsonismo inducido por telmisartán. PRESENTACIÓN DE CASO: Hombre de 78 años, con antecedentes de enfermedad de Parkinson de dos años de evolución, controlada con levodopa, pramipexol ER y amantadina, ingresa al servicio de urgencias por empeoramiento del parkinsonismo en las dos semanas previas a la consulta. Tenía antecedente de infarto cerebral en el territorio de la arteria cerebral posterior izquierda, hipertensión arterial crónica y diabetes mellitus tipo 2. Al examen neurológico presentaba bradicinesia y rigidez severa en las cuatro extremidades, con limitación significativa de la marcha, asociado a mioclonías. Se descartaron alteraciones infecciosas, metabólicas y lesiones agudas en la tomografía cerebral, por lo que se suspendió el telmisartán, posteriormente a lo cual los síntomas mejoraron. DISCUSIÓN: El parkinsonismo secundario a fármacos constituye la primera causa de este síndrome, en varios modelos farmacológicos se describe la acción que estos ejercen sobre los receptores dopaminérgicos. Así, el parkinsonismo inducido por telmisartán se considera desencadenado por disrupción dopaminérgica secundaria al antagonismo de los receptores de la angiotensina II a nivel de la sustancia gris periacueductal.
SUMMARY INTRODUCTION: Parkinsonism is a clinical syndrome characterized by tremor, rigidity, and bradykinesia due to alteration in the basal-ganglia dopaminergic circuit, specifically at the nigrostriatal level. The following is a case of parkinsonism induced by telmisartan. CASE PRESENTATION: A 78-year-old man with a 2-year history of Parkinson's disease of controlled evolution with levodopa, pramipexole ER, amantadine was admitted to the emergency department due to worsening of parkinsonism in the two weeks prior to consultation. He had a history of cerebral infarction in the territory of the left posterior cerebral artery, chronic arterial hypertension, and type 2 diabetes mellitus. On neurological examination, he presented bradykinesia and severe stiffness in all four limbs with significant limitation of gait, associated with myoclonus. Infectious and metabolic alterations and acute lesions were ruled out in the brain tomography, so telmisartan was suspended, after which the symptoms improved. DISCUSSION: Drug-induced parkinsonism is the first cause of this syndrome, and the action they exert on dopaminergic receptors has been described in several pharmacological models. Telmisartan-induced parkinsonism is considered triggered by dopaminergic disruption secondary to angiotensin II receptor antagonism at the periaqueductal gray substance level.

BACKGROUND: High blood pressure is considered a disease and at the same time a cardiovascular risk factor, mainly involved in ischemic heart disease, cerebrovascular disease and kidney failure, causing high mortality worldwide. OBJECTIVE: The objective was to follow up with 24-hour ambulatory blood pressure monitoring in patients with high blood pressure belonging to a population with high cardiovascular risk. METHOD: Descriptive, observational, retrospective study, which analyzes 24-hour outpatient pressure controls of 1858 patients, in Cartagena, Colombia. RESULTS: 1173 exams were validated and included in the study. The median age was 66 years. 66.8% (783) were women and 33.2% (390) were men. The main changes occurred during the night, when 79.1% of the patients had high systolic pressure loads, 65.6% recorded diastolic pressure averages and 83.7% had abnormal circadian patterns. Only 11% of the studies were normal in all parameters. CONCLUSIONS: 24-hour ambulatory blood pressure monitoring proved to be a useful tool to identify uncontrolled hypertensive patients, detect nocturnal hypertension and abnormal circadian patterns, which are risk markers for cardiovascular morbidity and mortality.
ANTECEDENTES: La hipertensión arterial es considerada una enfermedad y al mismo tiempo un factor de riesgo cardiovascular, involucrada principalmente en la cardiopatía isquémica, la enfermedad cerebrovascular y la insuficiencia renal, causando una elevada mortalidad. OBJETIVO: Realizar seguimiento con monitoreo ambulatorio de la presión arterial de 24 horas en pacientes con hipertensión arterial pertenecientes a una población con alto riesgo cardiovascular. MÉTODO: Estudio descriptivo, observacional, retrospectivo, en el que se analizaron los monitoreos ambulatorios de presión de 24 horas de 1858 pacientes, en Cartagena, Colombia. RESULTADOS: Se incluyeron 1173 registros. La mediana de edad fue de 66 años. El 66.8% (783) fueron mujeres y el 33.2% (390) fueron hombres. Las principales alteraciones ocurrieron durante la noche, cuando el 79.1% de los pacientes tuvieron cargas elevadas de presión sistólica, el 65.6% registraron promedios elevados de presión diastólica y el 83.7% tuvieron patrones circadianos anormales. Solo el 11% de los estudios fueron normales en todos los parámetros. CONCLUSIONES: El monitoreo ambulatorio de la presión arterial de 24 horas demostró ser una herramienta útil para identificar a los pacientes hipertensos no controlados, detectando hipertensión nocturna y patrones circadianos anormales, los cuales son marcadores de riesgo para morbilidad y mortalidad cardiovascular.

Resumen El Síndrome de Parry Romberg es una enfermedad idiopática, caracterizado por la atrofia de tejido celular subcutáneo. Su signo clínico principal es la hemiatrofia facial progresiva con inclusión de piel, tejido subcutáneo, nervios, músculo y/o hueso. Se han propuesto diversas teorías, entre ellas el posible origen hereditario y genético de esta patología, debido a que se ha manifestado algunas veces en miembros de una misma familia. Se presenta un caso de una paciente con síndrome de Parry Romberg de inicio tardío, que cursó con atrofia de hemicara derecha desde los 20 años de edad asociada a epilepsia refractaria al tratamiento y con antecedente patológico familiar de un hermano que presenta igualmente atrofia en hemicara derecha y una marcada esclerodermia en golpe de sable.
Abstract Parry Romberg syndrome is an idiopathic disease, characterized by subcutaneous tissue atrophy. Its main clinical sign is progressive facial hemiatrophy including: skin, subcutaneous tissue, nerves, muscle and/or bone. Several theories have been mentioned, among them the possible hereditary and genetic origin of this disorder, as the manifestation of this disease sometimes is seen in members of the same family. We present a case: a patient with late presentation Parry Romberg, with right side face atrophy associated with refractory epilepsy and family history of a brother who presents right side face atrophy as well and a marked scleroderma in coup of saber.
RESUMO
Resumen La trombosis venosa cerebral (TSVC) es un tipo de accidente cerebrovascular (ACV) que involucra el lado venoso de la circulación cerebral, incluye trombosis de los senos venosos durales y/o de las venas corticales y profundas del cerebro, es una causa poco común 0,5-1 % de todos los accidentes cerebrovasculares, con una prevalencia estimada en el rango entre 0. 22 a 1,23 / 100.000 / año. Los factores de riesgo para TSVC, están generalmente divididos en riesgos adquiridos (por ejemplo: cirugía, trauma, embarazo, puerperio, síndrome antifosfolípido, cáncer, hormonas exógenas) y los riesgos genéticos (trombofilia hereditaria). Los factores de riesgo más ampliamente estudiados para TSVC incluyen estados protrombóticos, las trombofilias heredadas asociadas con TSVC incluyen deficiencias de antitrombina, proteína C, proteína S (PS), mutación del factor V Leiden y la mutación del gen 20210 de protrombina. La prevalencia del déficit de PS, oscila entre un 0,02 y un 0,03 % en la población general y aumenta hasta un 2 % en pacientes no seleccionados con trombosis. Con una mortalidad cercana al 9 %. El manejo es usualmente médico. Se cita el caso de una paciente de 28 años de edad, con cuadro clínico de cefalea de 1 mes de evolución, con hallazgos en neuroimagen de trombosis de senos transverso y sigmoideo izquierdo con déficit de proteína S.
Summary Cerebral venous thrombosis (TSVC) is a type of stroke (CVA) involving the venous side of the cerebral circulation, including thrombosis of the dural venous sinuses and / or cortical and deep veins of the brain, is a rare cause 0.5-1% of all strokes, with an estimated range between 0. 22 to 1.23 / 100,000 / year prevalence. Risk factors for TSVC, are generally divided into acquired risks (eg, surgery, trauma, pregnancy, postpartum, antiphospholipid syndrome, cancer, exogenous hormones) and genetic risks (hereditary thrombophilia). The most widely studied factors TSVC risk include prothrombotic states, inherited thrombophilia associated with deficiencies TSVC include antithrombin, protein C, protein S (PS), mutation of factor V Leiden mutation and prothrombin 20210 gene. The prevalence of PS deficit ranges between 0.02 and 0.03% in the general population and increases up to 2% in unselected patients with thrombosis. With close to 9% mortality. The operation is usually doctor. It cites the case of a 28-year-old, with clinical symptoms of headache 1 month of evolution with neuroimaging findings transverse sinus thrombosis and left sigmoid with protein S deficiency.

El cerebelo proviene del latín "pequeño cerebro", es aproximadamente una décima parte del cerebro en tamaño y peso, se encuentra en la fosa craneal posterior. está conectado directamente o indirectamente a una variedad de estructuras, incluyendo el tronco cerebral, la columna vertebral, las regiones corticales y subcorticales. El cerebelo contiene casi el 80 % del total de las neuronas del cerebro y se compone de formas diferenciadas de unidades neuronales, cada una compartiendo microcircuitos cerebelosos básicos. El cerebelo está formado por dos hemisferios laterales y una porción media o vermis . El cerebelo tiene varias funciones: coordinar los movimientos voluntarios especializados al influir en la actividad muscular y controlar el equilibrio, el tono muscular a través de conexiones con el sistema vestibular, la médula espinal y sus neuronas motoras alfa. Dentro de la corteza del cerebelo existe una organización somatotópica de las partes del cuerpo. El cerebelo es una pieza clave para el procesamiento de la información y participa en numerosas actividades motoras y no motoras, gracias a las características anatómicas de sus circuitos, las enormes capacidades de análisis y la alta conectividad con otras áreas del cerebro, puede verse afectado por diferentes factores como: anormalidades en el desarrollo embrionario, tóxicos, enfermedades autoinmunes, inflamatorias, vasculares y metabólicas, infecciones, tumores primarios y secundarios, traumas, iatrogénicos, enfermedades genéticas, esporádicas, dando origen a signos y síntomas que causan un síndrome cerebeloso de acuerdo al área anatómica comprometida. En la literatura científica no hay reportes de casos de síndrome cerebeloso por mesalamina (mesalazina). A continuación presentamos el primer caso.
Cerebellum is Latin for "little brain" is about a tenth of the brain in size and weight, is in the posterior cranial fossa. It connects directly or indirectly to a variety of structures, including brainstem, spinal cord, cortical and subcortical regions. The cerebellum contains almost 80% of all neurons in the brain and consists of different forms of neuronal units, each sharing basic cerebellar microcircuits. The cerebellum is formed by two lateral hemispheres and vermis or a middle portion . The cerebellum has several functions: coordinate movements specialized volunteers to influence muscle activity and control the balance, muscle tone through connections with the vestibular system, the spinal cord and alpha motor neurons. Within the cerebellar cortex somatotopic organization exists a body part. The cerebellum is a key to information processing and participates in numerous motor and non-motor activities, thanks to the anatomical characteristics of its routes, huge analysis capabilities and high connectivity with other brain areas, can be affected by different factors such as abnormalities in embryonic development, toxic, autoimmune, inflammatory, vascular and metabolic, infections, primary and secondary tumors, trauma, iatrogenic, genetic diseases, sporadic, giving rise to signs and symptoms that cause cerebellar syndrome according to compromised anatomical area. In the scientific literature no reported cases of cerebellar syndrome mesalamina (mesalazina), we report the first case.
RESUMO
PURPOSE: There is a lack of information from South America regarding factors that predict the clinical outcomes of patients treated medically for mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). This study was conducted to determine which of these factors are the most important. METHODS: This study included 110 South American patients with MTLE-HS treated with antiepileptic drugs. The factors considered included age, gender, age of epilepsy onset, interval between the lesion and the first seizure, central nervous system infection, traumatic brain injury, perinatal asphyxia, febrile convulsion, history of status epilepticus, types of seizures, site of hippocampal sclerosis (HS), extrahippocampal pathology, and electroencephalogram (EEG) abnormalities. The patients were divided into two groups based on the response to treatment: Group I, seizure free for at least two years; and Group II, not seizure free. RESULTS: On the multivariate analysis, the factors associated with a poor prognosis in terms of seizure frequency and control following treatment included the presence of an early onset of seizure, more than 10 seizures per month before treatment, and EEG abnormalities. CONCLUSION: The recognition of risk factors, such as early onset of seizures, more than 10 seizures per month before treatment, and EEG abnormalities, could lead to the identification of risk groups among patients with MTLE-HS and refractory epilepsy, possibly designating these individuals as candidates for early epilepsy surgery.

OBJECTIVES: To validate and translate the English version of the Neurologic Depression Disorders Inventory in Epilepsy (NDDI-E) into Spanish as a screening instrument for major depressive episodes (MDE) for patients with epilepsy from Argentina and Uruguay. METHODS: One hundred fifty-five consecutive outpatients with epilepsy participated in this study. The module of MDE of the MINI International Neuropsychiatric Instrument (MINI Plus version) was used as the gold standard against which the translated version of the NDDI-E was validated. RESULTS: Among the 155 patients, 25 (16%) met Diagnostic and Statistical Manual, Fourth Edition (DSM-IV) criteria for MDE according to the MINI. With a total score of >15, The NDDI-E identified MDE with an 80% sensitivity, 90% specificity, 60% positive predictive value, and 95.5% negative predictive value. SIGNIFICANCE: These data indicate that the Spanish version of the NDDI-E can reliably identify MDE in patients with epilepsy from Argentina and Uruguay.
