Situs inversus abdominal sin cardiopatía congénita y sin anomalías abdominales (levocardia aislada) / Situs inversus abdominals without congenital cardiopathy and abdominal malformations (isolated levocardia)

El situs inversus abdominal (SIA) es una anomalía infrecuente, con una incidencia que varía de 1 en 4.000 a 1 en 20.000 recién nacidos. Se asocia a una mortalidad elevada, dado que en el 95 por ciento de los casos se presenta con severas anomalías cardíacas y esplénicas. La existencia de un situs inversus abdominal solo, con corazón izquierdo (levocardia aislada) es muy poco frecuente, y cuando aparece este situs inversus abdominal parcial, suele estar asociado a obstrucción duodenal. Presentamos el caso de una niña de 11 meses, estudiada por bronquitis de repetición, que presenta un situs inversus abdominal con corazón en situación normal (levocardia aislada), sin anomalías cardíacas ni abdominales (AU)

[Favism (study of 8 families)]. / Favismo (Estudio de ocho familias).

This paper presents ten cases of total glucose-6-phosphate dehydrogenase (G-6-PD) deficiency in individuals with hemolytic crisis after exposure to products of the fava been ("Vicia faba"). Three other cases of total G-6-PD deficiency and eleven partial deficit cases of the enzyme, without associated hemolysis were detected in a total of forty individuals belonging to eight families of the province of Seville examinated for G-6-PD levels. Important differences were noted in the G-6-PD enzyme dosage taken during the crisis and six and twelve months after. This fact was interpreted as a secondary effect to the elimination of the enzymopenic cells because of hemolysis. Data suggests the existence of a relatively stable form of G-6-PD that could explain the dissociation between the incidence of deficit in G-6-PD level in the general population and the reduced casuist of favism reported in our literature.
