[Helicobacter pylori infection in childhood revealed by hematemesis endoscopic and pathologic patterns]

Helicobacter pylon infection frequency in hematemesis was scarcely studied. To asses the frequency of this infection in children with upper gastrointestinal bleeding and to study the endoscopic and histological features. It is a retrospective study including 180 children who underwent an endoscopy for upper gastrointestinal bleeding. Our population was divided in two groups. The group 1 [n=95] has performed gastric biopsy. The group 2 [n=95] has performed gastric biopsy. For each group, we studied the personal and familial history of gastroenterologic disease, the hospital where they come from, the importance of bleeding, the gastro-agressif drugs intake, the endoscopic and histological features. The helicobacter pylon infection was present in 48%of the children. The mean age of these children was 99.8 +/- 42.1 months versus 95.7 +/- 44 months [p=0.13]. The comparison of the two groups according to Hp infection, and the others parameters don't found any differences. All the infected children have chronic gastritis 40/40 versusl3/44 in the non infected children [p>10-6]. The frequency of Hp infection was high in this group of patients with upper gastrointestinal bleeding. It was probably underestimated because the investigation was not complete. We emphasize that Hp infection has to be investigated and systematically eradicated whenever there were severe symptoms like hematemesis indicating therefore organic disease

Dos casos de enteritis con bacteriemia por Campylobacter jejuni / Two cases of enteritis with bacteremia due to Campylobacter jejuni

Campylobacter es un importante agente causante de enfermedad en el ser humano en nuestro medio. Los casos de bacteriemia ocurren principalmente en pacientes inmunosuprimidos y sondebidos frecuentemente a C. fetus. Sin embargo la bacteriemia es un episodio que también se ha observado enpacientes con enteritis por C. jejuni. Referimos dos pacientes con enteritis grave y bacteriemia, ambos con enfermedades concomitantes compatibles con inmunodepresión: uno con síndrome nefrótico de larga data y otro con hepatopatía crónica con cirrosis. Destacamos que los dos casos presentaron hematemesis y uno de ellos,enterorragia. Sugerimos prestar atención a la coloración de Gram durante el subcultivo de los caldos conhemocultivos, en busca de formas características de esta especie, y en ese caso emplear medios de cultivo enmicroaerofilia a 37 y 42 °C

Campylobacter is an importantagent of illness in human beings. Bacteremia occurs principally in the immunocompromissed host and is frequently due to C. fetus. Nevertheless bacteremia also has been observed in patients with enteritis due to C. jejuni. We refer two cases of patients with severe enteritis and bacteremia, both of them with immunosupressive concomitant diseases such as nephrotic syndrome and chronic cirrotic hepatopathy. Both patients presented hemathemesis
