ABSTRACT

El absceso del músculo psoas es una piomiositis infrecuente en la población pediátrica, convirtiéndose en un gran reto diagnóstico. Esta condición debe sospecharse en todo niño con fiebre, malestar general o dolor abdominal, lumbar o de cadera con evolución mayor a una semana. Suele confundirse con artritis séptica u otras enfermedades osteomusculares, por lo que se requiere de la realización de imágenes diagnósticas; el desconocimiento de esta patología retrasa el inicio del tratamiento y genera gran morbimortalidad. Se presenta un caso atendido en un centro hospitalario pediátrico de tercer nivel de Bogotá, D.C. y se hace una revisión de la literatura enfatizando sus claves diagnósticas y el manejo terapéutico.


Psoas Abscess is a pyomyositis rarely present, which in turn makes its diagnosis a real challenge. This condition must be a differential diagnosis in children presenting fever, general malaise, lumbalgia, abdominal or hip pain for more than a week. It is frequently confused with septic arthritis or other musculoskeletal diseases, which is why radiographic studies or ultrasonography are necessary. Unawareness of this pathology delays its treatment, thus producing high levels of morbidity and mortality. A clinical case treated in a pediatric hospital from Bogotá, Colombia, is presented, as well as a literature review emphasizing in Psoas Abscess key issues and treatment.

ABSTRACT

Levels of Zn, Cu and Fe were measured in blood serum samples of 320 children: 160 boys and 160 girls randomly selected, ages between 7 and 14 years, all considered healthy and residing in the City of Merida, Venezuela. The metals were determined using flow injection analysis-flame atomic absorption spetrometry. There was a tendency for serum Zn (SZn) to increase with age. There was no significant difference in SZn levels between males and females in the different age groups. serum copper (SCu) decreases significanthy (p<0.05) with age in male children, whereas it increases in female children. The concentration of serum iron (SFe) tends to be lower than that reported in the literature. However, the age groups studied showed no statistically significant sex and age-related differences. the results are compared with values previously reporte for healthy children studied in other communities. The present study has shown that there is a complex interaction between SZn, SCu, SFe and age and sex of the children. On the other hand, our observations also suggest that more detailed studies of these metals should be done, and that study shoild include metabolic balances and associations betweem SZn, SCu, SFe and anthropometric variables (height, weight, body mass index and skinfold thickness)

ABSTRACT

En el presente trabajo se describen las alteraciones histoquímicas y bioquímicas renales producidas en conejos mediante la inyección intramuscular diaria de 100.000 UI de vitamina A, durante 7 días (hipervitaminosis A aguda). El estudio microscópico mostró hallazgos más frecuentes: hiperemia generalizada, hemorragias córticomedulares discretas y generalizadas, tumefacción de las asas glomerulares, edema de las células tubulares proximales y distales y la presencia de masas celulares multinucleares de forma, aspecto y tamaño variable en la luz tubular. Mediante técnicas histoquímicas y bioquímicas se pudo comprobar, en estos animales, incremento en el contenido renal de grasas neutrales y de fosfolípidos, mientras que los mucopolisacáridos ácidos, las proteínas totales y las nucleoproteínas tienden a disminuir significativamente (p<0.05). Las masas celulares endotubulares muestran una fuerte reacción positiva con la mayoría de las técnicas histoquímicas empleadas. En conclusión, la hipervitaminosis A aguda, confirmada por el incremento tisular de la vitamina A, tiene un efecto tóxico profundo y marcado sobre el riñón
