RESUMEN

Oral sodium phosphate (OSP) solutions are widely used for bowel cleansing before colonoscopy, for stercoral retention phenomena and persistent chronic constipation. Its main risk, is acute phosphate nephropathy (APN), which is a clinic-pathological entity characterized by acute kidney disease secondary to deposition of calcium phosphate crystals in the renal tubules. Its recognition has been documented over the last decade in relation to case reports and the warning of the FDA. This report discusses two cases of APN certified by renal biopsy after the administration of OSP. One of them had an acute symptomatic presentation, and the other one, was a late finding. Both developed renal failure.


Las soluciones de fosfato de sodio oral (FSO) son ampliamente utilizadas para la preparación de colon previo a colonoscopia, para fenómenos de retención estercorácea y constipación crónica pertinaz. Su principal riesgo, la nefropatía aguda por fosfatos (NAF), es una entidad clínico-patológica caracterizada por falla renal aguda secundaria a depósito de cristales de fosfato de calcio en los túbulos renales. En la última década se han comunicado reportes de casos clínicos y una advertencia del uso de FSO por parte de la Food and Drug Administration de EE.UU. (FDA). En esta publicación se comunican dos casos de NAF, posterior a la administración de FSO, confirmadas por biopsia. Uno de ellos tuvo una presentación aguda y sintomática y el otro fue un hallazgo tardío. Ambos se acompañaron de falla renal.

RESUMEN

There is a 10 years teaching experience for fourth year medical students and interns in a Chilean private hospital. The students attend an eight weeks practical course. The interns rotate during 16 weeks by specialties and make shifts. The hospital structure with Clinical Services and Medical-Surgical departments facilitates the teaching process. There are approximately 30,000 admissions per year with a mean stay of 3.7 days, that allow the students to be in touch with patients with different diseases that are managed with updated technology. We emphasize the ethical and clinical management of concrete problems of patients, self ¡earning and communication skills. The students evaluate their stay answering surveys and with semi structured interviews. Teaching is assessed by tutors and heads of departments, in clinical rounds, sometimes prepared by the students, by a thorough revision of problem oriented medical records and with practical and theoretical tests. The results of the program have been quite satisfactory for participants.

RESUMEN

There is a growing dissatisfaction among physicians towards their professional practice. This article tries to identify causes of this dissatisfaction and to explain the fears that physicians experience during their practice. The authors pose the hypothesis that physicians have non resolved internal problems with the application of technological advances and that medical practice has not changed along with the dramatic social changes that have occurred in the last decades. Medical organizations work in a confusing environment. Considering the main characteristics of medical work, the causes of difficulties and the reasons to explain the slowness of physicians to identify the problems and react, are analyzed. Finally some solutions are proposed to overcome this crisis.

RESUMEN

Background: There is a paucity of information about the epidemiology of acute renal failure in Chile. Aim: To perform a prospective multicentric survey of severe acute renal failure in Chile. Material and methods: All patients admitted to ten hospitals in Metropolitan Santiago, during a period of six months with severe acute renal failure, were studied. The criteria for severity was the requirement of renal replacement therapy. All patients information was gathered in special forms and the type of renal replacement therapy and evolution was registeres. Results: One hundred fourteen patients were studied (65 males, age range 18 to 87 years). The calculated incidence of acute renal failure was 1.03 cases per 1000 hospital discharges. The onset was nosocomial in 79 subjects (69%) and community acquired in the rest. Renal failure was oliguric in 64 cases (56%) and in 60% of patients it had two or more causative factors. Sepsis, isolated or combined with other causes, was present in 51 of patients. Other causes included ischemia in 47%, surgery in 26%, exogenous toxicity in 25%, endocenous toxicity in 11%, acute glomerular damage in 6% and obstructive uropathy in 6%. Cardiac surgery was responsible for 47% of post operative cases of acute renal failure. Intermittent conventional hemodialysis, continuous renal replacement techniques and daily prolonged hemodialysis were used in 66%, 29% and 2% of patients, respectively. Overall mortality was 45% and it was higher in oliguric patients. Gender, age, cause or the type of therapy did not influence survival. Nine percent of surviving patients had some degree of kidney dysfunction at discharge. Conclusions: There is still a great space for prevention of severe acute renal failure in Chile, considering the main etiologies found in this study.

RESUMEN

Acute interstitial nephritis is a mononuclear and sterile inflammation of the renal interstice caused by drugs, infections or immune phenomena. The clinical presentation is characterized by the triad of rash, fever and eosinophilia. We report a 32 years old man, in treatment with lamotrigine for depression, admitted to the hospital due to fever, abdominal pain, jaundice, cutaneus rash and malaise. Due to an oliguric renal failure of acute onset, a renal biopsy was done. The pathological study showed a granulomatous acute interstitial nephritis. He was started on hemodialysis and treated with cessation of the drug and corticosteroids, with complete recovery of the renal function (Rev Méd Chile 2004; 132: 742-6).

RESUMEN

Herod the Great was the founder of a dynasty that reigned on Judea for several generations. His birth date is estimated on year 73 AC and died at 70 years old. Descriptions of the final disease of Herod were obtained from the classical chronicles of Flavius Josephus, The Jewish war and Jewish Antiquities. A medical explanation for his death is attempted. A parasitism caused by Schistosoma haematobium is suggested as the etiology for chronic renal failure (edema, halitosis and orthopnea) and a "gangrene of genitalia that engendered worms" in the words of Josephus. This would be explained by the formation of genital and urinary fistulae, observed in such disease. The asseveration that Herod was attacked by black bilis is also discussed, based on the concepts of the Hippocratic medicine of that time.
