Interstitial Nephritis: Wherefrom, Wherein, and Whereto.

Abnormalities of the renal interstitium were noted early while identifying chronic kidney disease in 1827; however, interest in glomerular and vascular lesions was then distracted from their further study. As a complication of scarlet fever, interstitial lesions attracted attention in 1859 and came to be defined as acute interstitial nephritis in 1898. The chronic form of interstitial nephritis was traditionally attributed to pyelonephritis until the advent of kidney biopsy in the 1950s, when interstitial lesions were recognized as an independent primary cause of chronic kidney disease from studies of analgesic nephropathy and vesico-ureteral reflux. The term tubulointerstitial nephritis was introduced in 1963 and promoted to denote the role of the tubules in the pathogenesis and the clinical presentation of interstitial nephritis as tubular dysfunction. Studies since then have established that fibrotic tubulointerstitial nephritis lesions correlate best with the severity and progression of kidney diseases independent of their etiology.

Carlos II: Del hechizo a su patología génito-urinaria / Charles II: From spell to genitourinary pathology

OBJETIVO: Tratar de desentrañar la compleja patología del último rey de la dinastía de los Austrias, Carlos II, apodado El Hechizado, dentro de la cual la urogenital fue preponderante, impidiéndole cumplir con una de las finalidades de la institución monárquica cual es la transmisión a un descendiente y produciéndole una serie de complicaciones que le llevaron al fallecimiento.MÉTODOS: Revisamos las obras en las cuales se describe la vida del Rey, haciendo hincapié en sus antecedentes consanguíneos, en las dudas sobre su sexo en el momento del nacimiento, sus procesos patológicos, la repercusión en las Cortes Europeas, pero sobre todo en sus matrimonios y en la incapacidad para generar un heredero. Resaltamos como, siguiendo el pensamiento de la sociedad española del siglo XVII, hizo pensar que se encontraba hechizado. Sobrenombre con el que pasó a la historia.RESULTADO: Deducimos que pudo presentar un hipospadias posterior que junto con la monorquia y testículo atrófico, hace pensar que presentó un estado intersexual con genitales ambiguos. Su fenotipo físico inclina más hacia un hermafroditismo verdadero y sobre todo un varón XX, que hacia un síndrome de Klinefelter que ha sido el más atribuido. Es probable su asociación con un síndrome X frágil. Monorreno congénito muy posiblemente, su muerte se debió a una insuficiencia renal crónica producida por una glomerulopatía o una nefropatía intersticial a consecuencia de una litiasis renal más infecciones del tracto urinario recidivantes.CONCLUSIONES: Fruto de una reiterada política matrimonial endogámica, feneció en 1700 la dinastía de los Habsburgo en España encarnada en Carlos II, un monarca pluripatológico que sólo se libraría de especulaciones si se efectuaran estudios cromosómicos y genéticos de sus restos presentes en el monasterio de El Escorial(AU)

OBJECTIVES: We attempt to unravel the complex condition of the last king of the Hapsburg dynasty in Spain, Charles II, called The Bewitched, in whom a genitourinary disorder was preponderant, preventing him from fulfilling one of the objectives of the monarchial institution, engendering a heir, and causing a series of complications that led to his death. METHODS: We review the works describing the life of the King, with special emphasis on his bloodline, the doubts about his sex at birth, his pathological processes, the repercussion among European Courts, but above all on his marriages and the inability to engender an heir. We also emphasize the thought of 17th century Spanish society which led to the belief that he was bewitched. The nickname he passed into history with.RESULT: It was deduced that he could have presented posterior hypospadias which, together with monorchism and atrophic testicle, led to the belief that he presen-ted an intersexual state with ambiguous genitals. The physical phenotype leans more towards true hermaphro-ditism and above all a XX male, rather than the more often attributed Klinefelter’s syndrome. This is probably also associated with a fragile X syndrome. Very possibly congenital monorenal, death was due to chronic kidney failure caused by glomerulopathy or interstitial nephro-pathy as a consequence of renal lithiasis plus recurrent infections of the urinary tract.CONCLUSIONS: As a result of a reiterated endogamic matrimonial policy, the Hapsburg dynasty died out in Spain in 1700, represented by Charles II, a pluripatho-logical king who can only be freed from speculation by chromosomal and genetic studies of his remains buried in El Escorial monaster(AU)

[Additional information on the history of Balkan endemic nephropathy]. / Dopulnitelni svedeniia za istoriia na balkanskta endemichna nefropatiia.

The paper presents additional information to the bibliographic check up in the two papers of Asst. Prof. Dimitrov, published in the periodical "Vutreshni bolesti" in 1982 as regards the history of Balkan endemic nephropathy, being of importance for the early history of the disease. Some of the data not accurately cited in the two papers of Asst. Prof. Dimitrov are corrected. Critical notes are also presented about the erroneous interpretation of some of the early written scientific facts.
