Epilepsia de la infancia con paroxismos occipitales
Pozo Alonso,Albia; Pozo Lauzán,Desiderio; Pozo Alonso,Desi;
Revista Cubana de Pediatr?-a , 1999,
Abstract: is is reported that epilepsy of childhood with occipital paroxysms is an epileptic syndrome that is well defined. it is included in the group of related idiopathic epilepsies with localization. seizures habitually begin with visual symptoms, which are ocassionally followed by hemiclonic, complex partial, and generalized tonicclonic seizures. the interictal eeg shows spike-wave complexes of occipital and temporal posterior localization that are suppressed by eye opening. a patient aged 8 in whom the clinical and electroencephalographic criteria of epilepsy of childhood with occipital paroxysms are present is studied in this paper. emphasis is made on the apparently benign evolution of this syndrome.

Abstract: Se reporta que la epilepsia de la infancia con paroxismos occipitales constituye un síndrome epiléptico muy bien definido; se incluye en el grupo de las epilepsias idiopáticas relacionadas con localización. Los ataques comienzan habitualmente con síntomas visuales, en ocasiones seguidos por ataques hemiclónicos, parciales complejos y tónicoclónicos generalizados. El electroencefalograma interictal muestra complejos de puntaonda de localización occipital y temporal posterior que desaparecen con la apertura de los ojos. Se presenta una paciente de 8 a os de edad que reúne los criterios clínicos y electroencefalográficos de la epilepsia de la infancia con paroxismos occipitales y se enfatiza en la evolución supuestamente benigna de dicho síndrome.

Revista Cubana de Pediatr?-a , 2010,
Abstract: Existen numerosos fármacos antiepilépticos de primera y segunda generación, disponibles hoy en el mercado internacional y en Cuba. Sin embargo, no todos resultan satisfactorios para el control de las crisis, debido a dificultades de tolerancia y toxicidad, y a sus propiedades farmacocinéticas. Se ofrece una revisión sobre los principales medicamentos antiepilépticos de tercera generación que en a os recientes han sido investigados, para aumentar su eficacia y minimizar sus efectos colaterales, e introducidos en el arsenal terapéutico. Algunos fármacos continúan sometidos a ensayos experimentales y clínicos. There are many first and second generation antiepilectic drugs available in the international marked and also in Cuba.

Tortícolis paroxístico benigno de la infancia
Pozo Alonso,Albia J.; Pozo Lauzán,Desiderio; Pozo Alonso,Desi;
Revista Cubana de Pediatr?-a , 2001,
Abstract: bening paroxysmal torticollis of infancy is an episodic functional disorder that appears during the first months of life in a sudden and spontaneous way. the patient inclines the head towards a side for some hours or days. it may be associated with paleness, vomiting, ataxia and irritability. these pictures are recurrent and disappear gradually up to the age of 2 or 3. it is more frequent among females. in its pathogeny, it has been stated the existance of a peripheral vestibular dysfunction, as well as the presence of vascular alterations of the vestibulocerebellar conexions. the genetic origin has also been suggested. a 7-month-old female infant that meets the clinical criteria of this entity is presented. the medical literature related to this process and its main differential diagnoses are reviewed.
Epilepsias mioclónicas en el ni?o y el adolescente
Pozo Alonso,Albia J.; Pozo Lauzán,Desiderio; Pozo Alonso,Desi;
Revista Cubana de Pediatr?-a , 2001,
Abstract: the mioclonic epilepsies are rapid muscular contractions originated by a discharge that comes from the central nervous system and that are identified by the correlation of the eeg with the muscular jerk. the mioclonic epilepsies are a group of epileptic syndromes that evolve exclusively or preferably with myoclonic crises. they may be classified as idiopathic, symptomatic or cryptogenic according to their cause. they may be benign, severe or progressive depending on their evolution. the aim of this paper was to show the most important characteristics of some of the main mioclonic epileptic syndromes and to make emphasis on the clinical manifestations, eeg findings and the treatment used.
Síndrome de West: etiología, fisiopatología, aspectos clínicos y pronósticos
Pozo Alonso,Albia J.; Pozo Lauzán,Desiderio; Pozo Alonso,Desi;
Revista Cubana de Pediatr?-a , 2002,
Abstract: west syndrome is an age-dependent epileptic encephalopathy characterized by electoclinical triad of epileptic spasms, retardation of psychomotor development and electroencephalographic pattern of hipsarrythmia, although one of these elements may not be present. the majority of patients develop this syndrome in the first year of life. from the etiological viewpoint, western syndrome is idiopathic, cryptogenic and symptomatic. the prenatal causes are the most frequent ones. various hypotheses have been presented to explain the origin of west syndrome. epileptic spasms are the characteristic crises that can be in flexion, extension or combined. a review is made on important aspects of etiology, physiopathology, clinical manifestations, differential diagnosis and prognosis of west syndrome.
A propósito del síndrome de Ohtahara
Pozo Alonso,Albia J.; Pozo Lauzán,Desiderio; Pozo Alonso,Desi;
Revista Cubana de Pediatr?-a , 2003,
Abstract: ohtahara's syndrome is an epyleptic encephalopathy depending on age that present a varied origin. the clinical manifestations appear mostly during the neonatal period. the tonic spasms (up to 10 sec of duration), which are grouped in series or sporadic are the most common form of presentation. partial crises are observed in approximately the third part of the patients. there is a prevalence of males. the characteristic of the interictal electroencephalogram is the presence of generalized waves of great amplitude alternating with phases of suppression of the brain electrical activity. the main objective of this paper is to call the attention about the existance of this entity in the neonatal and early breast-feeding stage. a male patient of 16 days of age that began to have tonic spasms associated with severe hypotonia of the neck and trunk, with hypertonia of the limbs and eeg compatible with this entity, is presented. the cranial cat showed signs of brain atrophy of cortical predominance. the response to the treatment was unfavorable. this syndrome has a very severe prognosis and crises are highly resistant to treatment.

Revista Cubana de Pediatr?-a , 2001,
Abstract: Las mioclonías epilépticas son contracciones musculares rápidas originadas por una descarga que proviene del sistema nervioso central y que se identifican por la correlación del electroencefalograma con la sacudida muscular. Las epilepsias mioclónicas son un grupo de síndromes epilépticos que evolucionan exclusiva o preferentemente con crisis mioclónicas. De acuerdo con su causa pueden clasificarse en idiopáticas, sintomáticas y criptogénicas. Según su evolución pueden ser benignas, graves y progresivas. Fue propósito de este trabajo mostrar las características más importantes de algunos de los principales síndromes epilépticos mioclónicos y enfatizar en las manifestaciones clínicas, hallazgos electroencefalográficos y en el tratamiento empleado.

A propósito del síndrome de Ohtahara
Albia J. Pozo Alonso,Desiderio Pozo Lauzán,Desi Pozo Alonso
Revista Cubana de Pediatr?-a , 2003,
Abstract: El síndrome de Ohtahara constituye una encefalopatía epiléptica dependiente de la edad que presenta un origen variado. El comienzo de las manifestaciones clínicas ocurre en la mayoría de los pacientes en el período neonatal. Los espasmos tónicos (hasta 10 seg de duración), agrupados en series o también esporádicos, constituyen la forma más frecuente de presentación. Las crisis parciales se observan en aproximadamente la tercera parte de los pacientes. El sexo que predomina es el masculino. La característica del electroencefalograma interictal es la presencia de oleadas generalizadas de gran amplitud, que alternan con fases de supresión de la actividad eléctrica cerebral. El objetivo principal de este trabajo es llamar la atención de la existencia de esta entidad en la etapa neonatal y precoz de la lactancia. Se muestra un paciente del sexo masculino de 16 días de edad que comenzó con espasmos tónicos, asociados a hipotonía severa de cuello y de tronco, con hipertonía de los miembros y un electroencefalograma compatible con esta entidad. La tomografía axial computadorizada de cráneo mostró signos de atrofia cerebral de predominio cortical. La respuesta al tratamiento fue desfavorable. Este síndrome presenta un pronóstico muy severo y las crisis son muy resistentes al tratamiento. Ohtahara's syndrome is an epyleptic encephalopathy depending on age that present a varied origin.

The main objective of this paper is to call the attention about the existance of this entity in the neonatal and early breast-feeding stage. A male patient of 16 days of age that began to have tonic spasms associated with severe hypotonia of the neck and trunk, with hypertonia of the limbs and EEG compatible with this entity, is presented. The cranial CAT showed signs of brain atrophy of cortical predominance. The response to the treatment was unfavorable. This syndrome has a very severe prognosis and crises are highly resistant to treatment.
