Abstract: cataracts are one of the main causes of blindness all over the world and its surgical removal is the only effective therapy admitted. the opacity of the posterior capsule of the lens is the most frequent post-surgical complication. this may appear months or years after surgery and is present in 20-50 % of the patients after 5 years of their surgical intervention. the posterior capsulotomy may be performed by means of manual procedures using the traditional instrumentation, or by means of laser; the current technique nowadays. showing the results after laser capsulotomy in patients operated by the blumenthal technique (2007-2008) at "abel santamaria cuadrado" university hospital, in pinar del rio cuba was the purpose of this paper. age, sex, implant and non- implant of the intraocular lenses (iol), complications during trans and post laser therapy, as well as the visual acuity before and after treatment were the variables considered, all patients were older than 60 years (80, 2 %) and in 96, 8 % an intraocular lens was placed into the posterior chamber, 65.9 % of the eyes showed transient increasing of the intraocular pressure, and only 3, 2 % showed splintering of the iol, but needing no extraction. complications were not so important if it is considered that 93, 2 % of the eyes reached to a visual acuity > 0, 7.

Abstract: La catarata es una de las principales causas de ceguera en todo el mundo y su extracción quirúrgica es la única terapia admitida como eficaz. Dentro de las complicaciones más frecuentes está la opacidad de la cápsula posterior del cristalino, ésta puede aparecer meses o a os después de la cirugía. Ocurre entre el 20% y el 50% de los pacientes en un periodo de 5 a os posteriores a la misma. La capsulotomía posterior puede realizarse mediante maniobras manuales con el instrumental tradicional, o con láser, siendo este último la modalidad habitual en la época actual; por estas razones se realiza esta investigación, para conocer los resultados obtenidos después de la capsulotomía con láser en los pacientes operados de catarata por la Técnica Blumenthal en el Hospital Universitario Abel Santamaría Cuadrado, en Pinar del Río (Cuba), durante el periodo junio 2007-mayo 2008. Para ello se tuvieron en cuenta las variables: edad, sexo, implante o no de lente intraocular, complicaciones trans y post láser, así como agudeza visual pre y post tratamiento. El 80.2% de los pacientes estudiados tenía >60 a os de edad y en un 96,8% se colocó lente intraocular en cámara posterior. El 65.9% de los ojos presentó elevación transitoria de la presión intraocular y sólo en un 3.2% hubo astillamiento del lente intraocular sin necesidad de extracción. Las complicaciones no cobraron importancia si se considera que el 93.2% de los ojos alcanzó una agudeza visual >0.7.

Abstract: Se realizó una revisión, análisis y estudio a 126 mujeres con linfedema posmastectomía, durante 7 a os. El tratamiento consistió en recomendaciones para las mastectomizadas, un equipo para facilitar el drenaje linfático y un plan de ejercicios. Del total de las pacientes, 25 fallecieron durante el estudio y 35 lo abandonaron. Las 66 pacientes restantes en su totalidad fueron atendidas y tratadas en consulta externa. El control del volumen de sus brazos se efectuaba mediante volumetrías con un equipo dise ado al efecto. De ahí que se clasificaba a la paciente de acuerdo con el volumen. De ellas, 12 se encontraban en la etapa I (edema leve), 19 en la etapa II (edema moderado) y 35 en la etapa III (edema severo). Con el nombre de método RED se lleva a cabo la investigación y el tratamiento. Según los resultados obtenidos, el 42,8 % de las pacientes de la etapa III pasó a la etapa II, el 52,6 % de la etapa II pasó a la etapa I y el 66,6 % de la etapa I quedó prácticamente sin edema alguno.

El marqués de Cervera y el derecho de los cubanos fieles a ser ciudadanos espa oles después del 98
Díaz Hernández, Magdalena
Anuario de Estudios Americanos , 2008,
Abstract: After the Paris Treaty in 1898, Spain refused Cubans who had supported it in the Independence War of the last Spanish colonies, their wish and right of keep on being Spanish citizens. As a consequence, they also lost their wages. That was the reason why the marques of Cervera defended them, writing a Manifiesto to the regent Queen and the Spanish Court in 1901, in which he proclaims the historical and cultural identity that Spain and Cuba had shared, like the best lure to make possible the recovery of their rights as older Spanish citizens, still living in Cuba. Tras la firma del Tratado de París de 1898, Espa a negó con fórmulas jurídicas el deseo y el derecho de los nacidos en Cuba que la habían apoyado durante la guerra de Independencia de las últimas colonias, a seguir siendo ciudadanos espa oles y, por lo tanto, a percibir sus sueldos ganados al servicio de Espa a. Por este motivo, el marqués de Cervera se erigió en defensor de éstos, escribiendo un Manifiesto que remitió a la reina regente y a las Cortes en 1901, en el que proclama la identidad histórica y cultural compartida entre Espa a y Cuba, para hacer posible la recuperación de sus derechos como antiguos ciudadanos espa oles, que siguieron residiendo en la isla de Cuba.
Una visión sucinta de la ense?anza de la medicina a lo largo de la historia: I. Desde el Antiguo Imperio Egipcio hasta el siglo XVII

Abstract: in order to understand how medicine has been taught through the years, it is necessary to refer to historians who have approached the evolution of medicine. taking them as a starting point, it is possible to describe the attitudes of doctors in their role as professors, and the ways in which students acquired knowledge at different moments throughout centuries. this article presents a succinct vision of the advances and retrogressions in medical teaching at different historical moments. it starts with the ancient egyptian empire (3000-2500 b. c.) with its big legacy written on papyruses; continues with the enormous progress of greek medicine and the obscurity of the middle ages, and finishes with the advances until the xvii century.

Análisis de los factores de riesgo en el linfedema posmastectomía
Díaz Hernández,Orestes L.;
Revista Cubana de Higiene y Epidemiolog?-a , 2000,
Abstract: risk factors of the post-mastectomy lymphedema were studied and analyzed in the outpatient department of angiology and vascular surgery where 120 patients mastectomized from breast cancer, 95 of them with post-mastectomy lymphedema, and 25 cosdntrols were studied. the variables to be analyzed were divided into 2 groups: one with primary risk factors such as tumor stage, radiotherapy, type of mastectomy, surgical complications and the condition of pathological ganglia and the other with secondary risk factors like lymphangitis, spleen fibrosis, bracchial plexitis, arterial, venous and lymphatic flow and scar retraction. of the primary risk factors, the axillary dissection reached a relative risk of 1.32 with a p < 0,05 and the rest pf tjese factprs were not considered important risks for edema formation. all the secondary risk factors had a relative risk over 3 with p < 0,05 for all the analyzed factors. the axillary dissection associated with radiotherapy may contribute to the formation of an edema due to the chronic lymphatic occlusion that occurs. additionally, if there is an axillary vein thrombosis or an acute lymphagitis in the arm, a scar retraction takes place in the axilla, the arm becomes fibrotic, and the affected bracchial plexus hinders the movements of the upper limb, the the lymphedema may take a grotesque dimension. careful axillary dissection to avoid affecting nerves and vessels and radiotherapy with adequate dosage may reduce the possibilities of lymphatic edema. we strongly recommend the strict control of the risk factors that have been analyzed and studied in this paper.
