Carcinoma papilar quístico y del tiroides: Estudio de 4 casos Tryroid cyst papillary carcinoma: Study of four cases
Adalberto Infante Amorós,Ana del Carmen Argüelles Zayas,Ramón González Fernández,David Cubero Rego
Revista Cubana de Medicina , 2004,
Abstract: Se presentaron 4 casos de carcinoma papilar quístico en el período de 4 a os. Se realizó examen físico de todos los casos; se encontró una masa cervical firme en la cara anterior del cuello y en 2 de ellos, se palparon adenopatías cervicales. Se aplicaron técnicas de imagen (ecografía cervical y gammagrafía tiroidea); se completó el estudio con BAAF, que tuvo valor diagnóstico en el 75 % de los casos. Se realizó un estudio anatomopatológico de todas las piezas obtenidas. Se hizo la resección del quiste, biopsia intraoperatoria y si se confirmó el diagnóstico de carcinoma papilar quístico, se le realizó una tiroidectomía total y si fue necesario, linfadenectomía. Se completó el tratamiento con I131 a dosis ablativa y tratamiento hormonal supresor de la TSH. Se destacó el papel de la BAAF en el estudio preoperatorio. 4 cases of cyst papillary carcinoma in a period of 4 years were presented. All of them underwent physical examination. A firm cervical mass was found in the anterior side of the neck and cervical adenopathies were palpated in 2 of them. Imaging techniques (cervical echography and thyroid gammagram) were applied. The study was completed with FNAB, which had a diagnostic value in 75 % of the cases. An anatomopathological study of all the pieces obtained was conducted. Resection of the cyst and intraoperatory biopsy were performed. In those cases with confirmed diagnosis of cyst papillary carcinoma, total thyroidectomy was carried out and, if necessary, lymphadenectomy. The treatment was concluded with I131 at ablative doses and TSH -supressing hormonal treatment. The role of FNAB in the preoperative study was stressed.

Los pila del poblado ibérico de Castellruf
álvarez Zarza, Ramón,Cubero Argente, Manuel
Gladius , 1999, DOI: 10.3989/gladius.1999.16
Abstract: In this paper we present a group of Roman republican pila from the Iberian Iron Age site at Castellruf (Val l é ~O riental, province of Barcelona, Catalonia, northeast of Iberia). These weapons can be dated to the end of the third century BC, which puts them among the earliest known republican pila. They belong to the same type. At the same text, the historical and cultural context for these objects is analysed. En este artículo se presenta un conjunto de pila romanos republicanos, datables hacia fines del s. 111 a.c., y procedentes del poblado ibérico de Castellruf (Vallés Oriental, Barcelona). El lote es tipológicamente homogéneo y especialmente importante por su cronología antigua entre los pila republicanos de los que en este artículo se presenta una visión general.

Abstract: acute leukemia during neonatal period is not frequent, of a fast course and gloomy prognosis. its clinical and biological features differ of that present in older children and it onset is characterized by cutaneous affection, hepatosplenomegaly, hyperleukocytosis and infiltration of central nervous system (cns). there are patients presenting with myeloid and lymphoid types, but the acute leukemia seems to predominate in this stage of life. this is the case of a patient with acute leukemia morphologically classified, with appearance of clinical manifestations of hematologic disease from birth and a diagnosis of congenital acute lymphoblastic leukemia.
Automatic Shape Recognition of Hand Gestures Using an Edge-tracing Vision System
Samuel N. Cubero
International Journal of Image Processing and Visual Communication , 2012, DOI: ijipvcv1i301
Abstract: This paper describes a working computer visionsystem and software algorithms that can automatically recognizedifferent types of hand gestures. The software performs theimage capture, analysis and shape identification for threedifferent kinds of hand gestures, namely, the ‘rock’, ‘paper’ and‘scissors’ hand gestures used in a popular child’s game. Thesoftware is comprised of three main elements, namely: (1) Amethod for collecting data to store normalized or ‘template’(standard) images of known shapes or known hand gestures; (2)An edge detection algorithm; and (3) A method to compare animage with normalized or ‘template’ images. This method ofhand gesture recognition could be adapted for use in manypractical applications relating to the control of computers (e.g.3D graphics, controlling games, real-time simulations), robotmanipulators, mobile robots and machinery.
Demencia con cuerpos de Lewy: Presentación de 1 caso

Revista Cubana de Medicina , 2004,
Abstract: it has been stated that dementia is the fourth basic cause of death in first world countries. dementia with lewy bodies (dlb) is the second cause of dementia in current necropsic studies, only surpassed by alzheimer's disease. the first cuban case of dementia with lewy bodies was reported. a female white patient aged 89 with clinical diagnosis of dementia that died after 5 years of progressive deterioration. in the neuropathological study, the presence of lewy bodies at the level of the black matter, locus ceruleus and transentorhinal cortex was evidenced by using the haematoxylin/eosin technique. the neurofibrillar pathology assessed by bielschowsky technique corresponded to ii stage braak. a focal espongiform change was identified at the hippocampal level. the diagnosis of lbd variety with predominance of the brain stem was made. literature and the main differential diagnoses were reviewed.
Demencia con cuerpos de Lewy: Presentación de 1 caso Dementia with lewy bodies: A case report

Abstract: Se ha planteado que la demencia constituye la cuarta causa básica de muerte en países del primer mundo. La demencia con cuerpos de Lewy (DCL) constituye la segunda causa de demencia en estudios necrópsicos actuales, superada solo por la enfermedad de Alzheimer. Se reportó el primer caso cubano de demencia con cuerpos de Lewy, una paciente femenina de 89 a os de edad, de la raza blanca, con diagnóstico clínico de demencia, que falleció luego de 5 a os de deterioro progresivo. En el estudio neuropatológico se evidenció con la técnica de hematoxilina / eosina la presencia de cuerpos de Lewy al nivel de la sustancia negra, locus cerúleo y corteza transentorrinal, la patología neurofibrilar valorada con la técnica de Bielschowsky se correspondió con un estadio II de Braak. Se identificó además cambio espongiforme focal al nivel del hipocampo. Se hizo el diagnóstico de DCL variedad a predominio del tallo cerebral. Se revisó la literatura y los principales diagnósticos diferenciales. It has been stated that dementia is the fourth basic cause of death in first world countries.

Kupffer cells and alcoholic liver disease
Cubero,F. J.; Nieto,N.;
Revista Espa?ola de Enfermedades Digestivas , 2006, DOI: 10.4321/S1130-01082006000600007
Abstract: liver disease is a major cause of illness and death worldwide. a central component in the complex network leading to the development of alcoholic liver disease is the activation of kupffer cells by endotoxin and other soluble mediators. alcohol consumption induces a state of ‘leaky gut' increasing plasma and liver endotoxin levels. when kupffer cells become activated, they interact with a complex of proteins located on the extracellular membrane signaling to produce a wide array of soluble factors, including cytokines, chemokines, growth factors, cyclooxygenase and lipoxygenase metabolites, and reactive oxygen species such as superoxide anion, hydrogen peroxide, and nitric oxide, all of which provide physiologically diverse and pivotal paracrine effects on all other liver cell types and, ultimately, liver injury. kupffer cells are also central to the liver homeostatic response to injury as upon cellular degenerative changes, they immediately respond to the insult and release mediators to orchestrate inflammatory and reparative responses. thus, the homeostatic responses are initiated by kupffer cell-derived mediators at the cellular level and underlie the liver's defense and reparative mechanisms against injury. in order to understand better the role of kupffer cells in the onset of liver injury, animal models in which kupffer cells are inactivated, and cell culture settings (e.g. co-cultures) are being used with promising results that advance our understanding of alcoholic liver disease.
