ABSTRACT

During history, amylidosis was observed associated to a great variety of inflammatory diseases, and due to this, appeared the term "secondary amyloidosis". The forms of sudden presentation without any apparent cause are classified as "primary amyloidosis", and also the localized amyloidosis was characterized, the same as the heredity variant. At present, three main grops are recognized as systemic amyloidosis: amyloidosis of light chains, the amyloidosis associated to the seric protein A, and the hereditary form. Systemic amyloidosis can involve practically any organ system, being the most commonly affected the heart and the kidney, which therefore determine the clinical evolution and the prognosis of the patient. The aim of this report, was to present a case of autopsy of systemic amyloidosis with involvement of the Central Nervous System, considering besides, the great extension of the disease in our patient

ABSTRACT

This study examines a description of pituitary tumors considering an anatomopathological casuistic. The study of the tumors of the Central Nervous System (CNS) include the pituitary gland, located in the sella turcica. The pathology of the sellar region is represented by the adenomas, tumors of slow development with or without endocrine secretion, that usually involve the population of young adults. The aim of this report, was to describe the casuistic of the " J. Fernandez Hospital" between the years 2000 through 2017. A retrospective review was performed and 234 samples of the sellar region were processed. Mean age was 42 years with a range of 17 to 77 years. Sex distribution was 57% women and 43 % men. Of these, 77% of the cases resulted adenomas. The conclusions obtained in the study are detailed.

ABSTRACT

Renal biopsy is a key procedure for the evaluation and management of the renal diseases, in order to establish a certainty diagnosis, to perform an adequate treatment and to determine the prognosis, while it results in a fundamental tool, but not all the medical centers have the necessary requeriments to carry them succesfully so that it can achieve the maximum benefit, lessen the posible complications, since as it is an invasive technique, always exists a certain risk inherent to the procedure, being the technique of choice the percutaneous renal biopsy guided by ultrasound. The aim of this report, is to know the incidence of the reanl pathology, in kidney biopsies in our Hospita, between July 2008 through July 2017, by mean of a descriptive and retrospective study. Two-thousands and eightsi-six reanl biopsies were analyzed in that period, and we analyzed the frequency of the disease diagnosed, the origin of the samples and thir quality, the age range of the population studied, as well as the complications of the method employed

ABSTRACT

La Nefropatía por Inmunoglobulina A (NIgA), también conocida como enfermedad de Berger, fue descrita por primera vez en 1968 por Berger e Hinglais. Se trata de una enfermedad heterogénea, tanto desde el punto de vista clínico, como histológico, caracterizada por la presencia de depósitos mesangiales de IgA. La clínica de presentación es extremadamente variable, pudiendo manifestarse desde microhematuria aislada hasta un deterioro agudo de la función renal por una glomerulonefritis extracapilar superpuesta. Inicialmente se la consideraba una entidad de buen pronóstico, pero con el paso del tiempo y a partir de un mayor conocimiento de la NIgA, se constató que la realidad era otra y que del 20 al 30% de los pacientes a los 20 años evolucionaban a la insuficiencia renal crónica (IRC) terminal y otro 20% mostraba una pérdida significativa de la función renal. En el presente artículo se describe un caso clínico de un paciente en el que se detectan casualmente marcadores de daño renal en la orina, y en quien los hallazgos histológicos observados en la biopsia renal modificaron su pronóstico y la conducta terapéutica. A partir de este caso clínico se realiza una actualización sobre la Nefropatía por IgA


Inmunoglobulin A (NIgA) Nephropathy also known as Berger disease, was described for the first time in 1968 by Berger and Hinglais. It is a heterogeneous disease, not only from clinical point of view but also from the histologicalone. Characterized by the presence of IgA mesangials deposits. Clinical presentation is extremely variable and can vary from isolated microhematuria up to a severe damage of renal function due to superimposed extracapillary glomerulonephritis. Initially it was considered an entity with good prognosis, but over time and more knowledge about IgAN, it was shown that 20 to 30% of 20 years old patients evolved to end stage renal failure and other 20% had important renal function loss. In the present article we describe a case of a patient in whom we detected by chance renal damage markers in the urine, and then the histologic findings observed in renal biopsy, modified the prognosis and therapeutic procedure. From this clinical case, we performed an update on IgA Nephropathy

ABSTRACT

Las vasculitis ANCA asociadas son la causa más frecuente de síndrome pulmo-renal (SPR); dentro de este grupo se halla la poliangeitis con granulomatosis (GPA). El objetivo de este trabajo fue describir las características clínicas y de laboratorio de pacientes con SPR y GPA, y comparar su sobrevida con un grupo de GPA graves sin SPR. Se revisaron retrospectivamente las historias clínicas de 37 casos de GPA pertenecientes a dos centros terciarios de la Ciudad de Buenos Aires. Se incluyeron para el análisis 13 casos con GPA/SPR; 7 fueron de sexo femenino, la media de edad al diagnóstico fue de 48 años. La media de seguimiento fue 4.66 años. El Birmingham Vasculitis Activity Score (BVAS) inicial fue de 31.13 ± 7.99 vs 18.19 ± 4.45 en el grupo de GPA sin SPR. Doce casos fueron ANCA-c positivos. El tratamiento consistió inicialmente en esteroides y ciclofosfamida; en los casos cuyo compromiso renal fue severo (creatinina plasmática 5mg/dll) se realizó plasmaféresis y diálisis. Se obtuvo la remisión de 8 casos; 2 recayeron durante el seguimiento. Se observaron 6 muertes; 2 fueron debidas a la actividad de la enfermedad, 3 debidas a infecciones y 1 a un accidente cerebrovascular. Todos fallecieron dentro de los 12 meses posteriores al diagnóstico. La mortalidad a los 30 días fue 38.46% en el grupo de GPA/SPR vs. 4.16% en el grupo de GPA sin SPR. El SPR es una de las formas más graves de la GPA y conlleva una elevada morbimortalidad. El diagnóstico debe ser rápido, excluyéndose otras posibles etiologías para poder instaurar un adecuado tratamiento que pueda modificar la mortalidad temprana que se observa en este síndrome. La determinación precoz de los ANCAs en el contexto clínico adecuado sería una herramienta de gran utilidad diagnóstica.
