[The evaluation of the kidney transplant patient by nuclear medicine technics]. / La valoración del paciente con trasplante renal por medio de técnicas de medicina nuclear.

In Mexico, approximately between 200 to 250 patients received a renal transplantation each year. Immediately after the surgical procedure it is important to evaluate the function of the transplanted kidney. Because some complications may arise mainly with unspecific symptoms which often produce oliguria, high levels of serum creatinine, fever and pain at the site of the graft. In this paper we report the nuclear medicine methodology, which we use in the diagnostic evaluation of this patients. These methods are highly specific and provide useful quantitative and qualitative information about these morphology and the function of the transplanted kidney.

[Hemophilic arthropathy. The therapeutic approaches in the clinical picture of hemophilia]. / Artropatía hemofílica. Enfoques terapéuticos en la clínica de hemofilia.

The ambulatory treatment of hemophilic arthropathy decreased the amount of replacement therapy with factor VIII from 3,220,000 U in 1984 to 2,217,700 U (32%) in 1988. Radioactive synovectomy diminished the number of hemarthroses in 97 per cent. Intraarticular dexamethasone reduced bleeding episodes and improved joint function in 48 per cent. These procedures for hemophilic arthropathy allowed to integrate the patient into society and diminished transfusion risks.

[Nutritional evaluation and use of a nutritional complement in children undergoing periodical hemodialysis]. / Valoración nutricional y uso de un complemento alimenticio en niños en hemodiálisis periódica

Six uremic dhildren in periodic hemodialysis with protein-calorie malnutrition were studied. Three of them were given diet supplementation with a compound constituted by carbohydrates and essential amino acids. Evaluation at ,3 and 6 months with somatometry, rutine laboratory analysis, intravenous glucose tolerance test and plasma amino acid determinations, showed that patients with diet supplementation had a slight increase in height and body weight, improved glucose in tolerance, that was initialy detected, and an abnormal pattern of plasma amino acids not modified during the study. Patients without diet supplementation showed no changes in height, body weight, glucose tolerance and plasma amino acids. These results suggest that diet supplementation with carbohydrates and amino acids is useful to improve nutrition in uremic children on hemodialysis, but it is neccesary to study more patients.

[Hemodialysis with low sodium concentration in hypertensive uremic children]. / Hemodiálisis con baja concentración de sodio en niños urémicos hipertensos

In three hypertensive uremic children in whom hypertension was not controlled by sodium-free diet, ultrafiltration and hypotensive drugs, a total of twenty low sodium concentration hemodialyses were carried out. In all patients there was insignificant sodium excretion in urine and diastolic blood pressure diminished 10 to 20 mm Hg; two patients showed also reduction of systolic blood pressure. No important changes were seen in the serum concentrations of sodium, calcium and glucose. In one patient improvement of his retin lesions, as well as radiological reduction of heart size were observed. In other two cases, cardio-respiratory symptoms associated with hypertension disappeared. In all but two of them hypotensive drugs were withdrawn; in the other one dose was reduced. With low sodium concentration hemodialysis, sodium extraction was higher than that obtained when using the conventional dialysis solution. Interchangeable sodium decreased in all patients.
