The term Neurocristopathy describes a group of conditions caused by aberrations in growth, migration and differentiation of neural crest cells. In this sense, Hirschsprung's disease is a consequence of a failure in neural crest cells migration to distal intestine and in consequence it is considered to be part of neurocristopathy concept. This concept includes several diseases that can present either alone or in combination as a syndrome. We present 4 patients suffering Hirschsprung's disease associated with others neurocristopathies: 1 Waardenburg's syndrome, 1 congenital central hypoventilation syndrome or Ondine's curse, 1 ganglioneuroblastoma and 1 patient with bilateral sensory deafness.

Motor vehicle crashes cause 28% of morbidity and mortality in children. A proper medical evaluation of the polytraumatized patient is essential to reduce these numbers. The aim of our study is to correlate clinical and radiological signs in patients with seat belt mark, to establish an early diagnosis of internal injuries. ⋯ All our patients (100%) with a seat belt mark presented abdominal injuries. The treatment is frequently delayed due to the difficulty in establishing the diagnosis. The finding of cutaneous ecchymosis caused by the lap belt must be a warning sign to suspect abdominal injuries. The CT scan is the most effective imaging technique to study patients with seat belt mark.
