Comparacion de dos pruebas para determinacion de productos liticos de fibrina. / A comparison of two tests for detection of fibrinogen fibrin degradation products

Se estudiaron 19 ninos con edades comprendidas de 5 dias a 18 meses, con factores desencadenantes o sospecha clinica de coagulacion intravascular diseminada. Se hicieron para su comparacion, 50 pares de determinaciones para productos liticos de fibrina mediante la tecnica de aglutinacion por estafilococo y aglutinacion con particulas de latex (25 para cada una). La cifra media para la primera fue de 18.24 mcg/ml. El analisis estadistico mediante la correlacion de Pearson dio como resultado una "r" de 0.80 que equivale e una "p" menor de 0.01

Ventajas de la oximetria transcutanea en el paciente pediatrico criticamente enfermo. / Advantages of transcutaneous oxymetry in the critically ill pediatric patient

Se estudiaron 38 pacientes con edades comprendidas entre 48 horas a 10 anos, que ingresaron al Servicio de Terapia Intensiva Pediatrica, con insuficiencia respiratoria aguda, a quienes se les determino simultaneamente la presion transcutanea de oxigeno (PtO2) y presion arterial de oxigeno (PaO2), para comparacion. Se estudiaron los efectos de diferentes factores como: temperatura corporal, edema de piel, sitio de colocacion del electrodo, aspiracion de secreciones, etc. Se compararon 37 pares de determinaciones y se encontro una correlacion significativa: r=0.907, p < 0.001 para los valores de PO2

[The value of the staphylococcal clumping test in the diagnosis of disseminated intravascular coagulation in the infected infant]. / Valor de la aglutinación por estafilococo en el diagnóstico de CID en el lactante infectado.

The staphylococcal clumping test for measurement of fibrin split products is a simple, rapid and trustworthy method in the diagnosis of disseminated intravascular coagulation. Three groups of patients were studied, a) with anatomicopathological findings of DIC, 26 cases; b) with predisposing factors for DIC, 50 cases and c) control group, 50 cases. The p value was less than 0.001 for the staphylococcal clumping test, equivalent to 100% trustworthiness in confirming the diagnosis of DIC.

[Fanconi syndrome with hepatic cirrhosis. Presentation of a case]. / Síndrome de Fanconi con cirrosis hepática. Presentación de un caso.

A male infant with clinical and radiological manifestations of hypophosphatemic rickets is presented. He had dysfunction of the renal tubular mechanisms of reabsorption manifested by: glycosuria, hyperaminoaciduria, hyperphosphaturia and high alkaline phosphatase plasma levels; associated with hepatic cirrhosis. Biochemical screening discarded most of the main known causes of Toni-Debré-Fanconi syndrome. Unfortunately, due to the low incidence of the syndrome and the patient's death, it was impossible to reach an accurate diagnosis. A review of the syndrome is presented.

Sindrome de Fanconi con cirrosis hepatica. Presentacion de un caso. / Fanconi's syndrome with liver cirrhosis. Presentation of a case

Se presenta el caso de un lactante masculino, con manifestaciones clinicas y radiologicas de raquitismo; alteraciones de la funcion tubular renal manifestadas por: glucosuria, hiperfosfaturia, hiperaminoaciduria, acidosis tubular, hipofosfatemia con calcio normal y fosfatasa alcalina elevada en plasma; asociados a cirrosis hepatica. Se realizaron estudios bioquimicos mediante los cuales se descartaron la mayoria de las causas conocidas del sindrome de Toni-Debre-Fanconi. Sin embargo, debido a la baja frecuencia del sindrome y al fallecimiento del nino, fue imposible llegar a un diagnostico de certeza

Valor de la prueba de aglutinacion por estafilococo en el diagnostico de CID en el lactante infectado. / Value of the agglutination test, by staphylococcus in the diagnosis of DIC in infected infants

La determinacion de productos liticos de la fibrina mediante la tecnica de aglutinacion por estafilococo, ofrece un indice de seguridad elevado en el diagnostico de coagulacion intravascular diseminada (CID). Se formaron 3 grupos de estudio para valorar su confiabilidad: a) anatomopatologico, 26 autopsias de pacientes con CID; b) clinico prospectivo, 50 pacientes con factores desencadenantes de CID y c) grupo control, 50 pacientes "sanos". Se encontro una confiabilidad muy alta (p menor de 0.001) al comparar los 3 grupos para la prueba de aglutinacion por estafilococo, lo cual proporciona practicamente un 100% de seguridad en la confirmacion de CID en lactantes infectados

[Renal vein thrombosis]. / Trombosis de vena renal.

Twenty-one autopsy protocols (1967-77) of children with the pathological diagnosis of thrombosis of renal vein were included in this study. Sixteen cases were bilateral and the remaining 5 were affected in one side. No correlation was found between pre and perinatal background to support the diagnosis. All facts showed electrolytic unbalance and severe metabolic acidosis. The coagulation tests showed unspecific disturbances. In six cases, it was possible to make pathological confirmation of disseminated intravascular coagulation. The classic triad of abdominal tumor, hematuria and uremia were found in a low percentage.

[Prognosis of respiratory arrest in children: apropos of 14 recovered children]. / Pronóstico del paro respiratorio en el niño: a propósito de 14 niños recuperados.

An analysis of 14 children from 1 month to 6 years of age who had respiratory arrest secondary to different causes, is presented. All patients except one, had also cardiac arrest at the same time. Main causes of respiratory arrest were neurological diseases and intoxications. A retrospective analysis on medical and ventilation support and management is presented. Evaluation of neurological status with developmental screening test of Denver, W.I.S.C. and Gessel was made and neurological deficit was detected only in two cases.

[Bilateral thrombosis of the renal vein. Report of a case]. / Trombósis bilateral en vena renal. Reporte de un caso.

A newborn baby with bilateral renal vein thrombosis is presented; diagnosis was made on clinical and radiological basis; she died with severe complications such as pulmonary hemorrhage and disseminated intravascular coagulation. It is emphasized that the bilateral form is rare and prognosis is variable depending upon clinical evolution.
