ABSTRACT

Las enfermedades renales son frecuentes, perjudiciales y tratables. Las jornadas internacionales por el Día del Riñón en su segundo año de celebración llama a la acción no sólo a los nefrólogos y pacientes renales, sino a médicos de todas las especialidades, enfermeras, científicos, expertos, administradores, gobiernos, para que estén conscientes de los desafíos que representa la Enfermedad Renal Crónica (ERC). En este artículo, se analiza el desarrollo de la Nefrología en Cuba y la relación de la ERC a otras enfermedades crónicas no transmisibles caracterizadas por el daño endotelial. Su prevención, diagnóstico y tratamiento es la vía común para contribuir a disminuir la morbimortalidad cardiovascular internacionalmente(AU)

ABSTRACT

It is possible that the mucosal damage in congestive gastropathy of portal hypertensive patients may have an ischemic basis, since rewarming time in other sites correlates with local blood flow, a method was designed to assess the capacity of the gastric mucosa to rewarm the stomach after a cold challenge, as an index of ischemia. Eleven control subjects and 15 patients with portal hypertension (10 treated with sclerotherapy) were studied with an integrated circuit temperature transducer connected to a digital display. A balloon containing the temperature transducer inside was reversibly fixed 10 cm. proximally to the distal end of a panendoscope. Once upper endoscopy was completed, the balloon placed in the antrum was infused with cooled water (2 degrees C) through a polyethylene tube. The time elapsed for the water to be rewarmed from 20 degrees C to 25 degrees C to 30 degrees C and 20 degrees C to 30 degrees C was measured. Reproducibility of repeated measurements, gave a coefficient of variation of 6


. Total rewarming time was (-mean +/- SD) 178 +/- 51.3 seconds, significantly higher in Portal hypertensive patients as compared to 114 +/- 34.7 seconds in Controls (P < 0.001). (95


Confidence Interval: -X = 63.4 seconds Cl 45.02 to 81.78). 60


of Sensitivity and 100


of Specificity The slower rewarming time in patients with portal hypertension may be the result of mucosal ischaemia, but oedema and cellular infiltration could also affect the heat flow.

ABSTRACT

By means of fiberendoscopic injection sclerotherapy, it was possible to achieve eradication of esophageal varices in 18 patients. At the onset of treatment 9 patients had small varices (grade II) and other 9 had big varices (grade III). It was found in the big varices group there was needed more courses (p less than 0.01) and a greater amount of sclerosing agent (p less than 0.001) than in the group with small varices. Since those patients with big varices required more courses and more volume of sclerosing agent, and in fact they have more risk to rebleed during the pre-eradication period. It is proposed as a solution during this period, the use of a B receptor blocking agent (Propranolol) simultaneously with sclerotherapy.

ABSTRACT

Mediante tratamiento esclerosante fibroendoscopico, se logro en 18 pacientes la erradicacion de sus varices esofagicas.Nueve pacientes presentaban al inicio de la terapeutica varices pequenas (grado III) y otros nueve varices grandes (grado III). Se comprueba que el grupo con varices grandes, requieren en forma estadisticamente significativa (p <0,01) mayor cantidad de sesiones y (p < 0.001) mayor volumen de esclerosante que el grupo con varices pequenas. Al requerir estos pacientes con varios esofagicas grandes mas sesiones y volumen de agente esclerosante, y ser al mismo tiempo los que tienen mayor riesgo de presentar recidivas hemorragicas durante el periodo preerradicatorio, se propone como solucion durante este lapso el empleo de los bloqueantes de los receptores B adrenergicos (propanolol) en forma simultanea a la escleroterapia
