New clues to understand gastroschisis. Embryology, pathogenesis and epidemiology / Nuevas pistas para comprender la gastrosquisis. Embriología, patogénesis y epidemiología

Abstract gastroschisis is a congenital structural defect of the abdominal wall, most often to the right of the umbilicus, through which the abdominal viscera protrude. Its developmental, etiological and epidemiological aspects have been a hot topic of controversy for a long time. However, recent findings suggest the involving of genetic and chromosomal alterations and the existence of a stress-inducing pathogenetic pathway, in which risk factors such as demographic and environmental ones can converge. . We have conducted a review of the medical literature that gathers information on the embryonic development of the ventral body wall, the primitive intestine, and the ring-umbilical cord complex, as well as on the theories about its origin, pathogenesis and recent epidemiological evidence, for which we consulted bibliographic databases and standard search engines

Resumen La gastrosquisis es un defecto estructural congénito de la pared abdominal, localizado con mayor frecuencia a la derecha del ombligo, a través del cual sobresalen las vísceras abdominales. Durante mucho tiempo, sus aspectos evolutivos, etiológicos y epidemiológicos han sido un tema candente de controversia, aunque hallazgos recientes sugieren la participación de alteraciones genéticas, cromosómicas, y la existencia de una vía patogénica inductora de estrés, en la que factores de riesgo como los demográficos y ambientales pueden converger. Con el objetivo de ampliar la frontera del conocimiento sobre una malformación que ha mostrado una creciente prevalencia global, hemos efectuado una revisión que incluye información, del desarrollo embrionario de la pared corporal ventral, el intestino primitivo, el complejo anillo-cordón umbilical, y de las teorías acerca de su origen, patogénesis e información epidemiológica reciente.

gastroschisis is a congenital structural defect of the abdominal wall, most often to the right of the umbilicus, through which the abdominal viscera protrude. Its developmental, etiological and epidemiological aspects have been a hot topic of controversy for a long time. However, recent findings suggest the involving of genetic and chromosomal alterations and the existence of a stress-inducing pathogenetic pathway, in which risk factors such as demographic and environmental ones can converge. To expand the frontier of knowledge about a malformation that has showed a growing global prevalence, we have conducted a review of the medical literature that gathers information on the embryonic development of the ventral body wall, the primitive intestine, and the ring-umbilical cord complex, as well as on the theories about its origin, pathogenesis and recent epidemiological evidence, for which we consulted bibliographic databases and standard search engines.

The importance of FDG PET/CT in the diagnostic process of the middle aortic syndrome in a 15-year-old boy patient with suspected systemic vasculitis and final diagnosis of Williams-Beuren syndrome.

The differential diagnosis in children with the systemic vasculopathy is still a challenge for clinicians. The progress in vascular imaging and the latest recommendations improve the diagnostic process, but only single reports describe the use of new imaging tests in children. The publication aims to demonstrate the important role of 18F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography combined with anatomical computed tomography angiography (PET/CTA) imaging in the case of a 15-year-old boy with chest pain, intermittent claudication, hypertension and features of middle aortic syndrome in computed tomography angiography (CTA). The patient was suspected to have Takayasu arteritis, but was finally diagnosed with Williams-Beuren syndrome. The case indicates that the FDG PET/CT imaging might be essential in the diagnostic process of middle aortic syndrome in children. We suggest that this imaging technique should be considered in the diagnostic process of systemic vasculopathy particularly in children.

Mid-aortic syndrome in a 3-year-old girl successfully treated by aorto-aortic grafting and renal artery implantation into the graft.

Mid-aortic syndrome, an uncommon acquired or congenital condition characterized by segmental narrowing of the abdominal or distal descending thoracic aorta, is frequently accompanied by ostial stenosis of the aorta's branches. If left untreated, it can result in life-threatening complications secondary to severe hypertension.We report the case of a 3-year-old girl with congenital mid-aortic syndrome, who was diagnosed by chance in the course of a viral illness, and whose high blood pressure values were first dismissed as inaccurate. Attempts to achieve medical or endovascular control of her hypertension were unsuccessful. She was thereafter successfully treated by aorto-aortic bypass grafting, resection of the stenotic segments of both renal arteries, and implantation of the patent arterial segments into the graft.
