We report four cases of acute bartonellosis (positive blood smear for Bartonella bacilliformis), who were present as an important complication, the thrombocytopenic purpura syndrome, a barely described complication for acute bartonellosis. The four cases were hospitalized in the Victor Ramos Guardia Hospital, and all of them are from the endemic zone of Ancash; three are natives and one live 5 years ago in this place. The range of the age was 14 -33 years; the time of the disease, 14-30 days; the parasitic index, 2%-62%. They presented with anemia, fever, epistaxis, petechiae and purpura; two cases had jaundice and hepatoesplenomegaly. The haemoglobin was between 5,6 and 9,7 g/dL; the leukocyte count was between 6 000 to 46 000/mm3 and the platelets were between 5 000 to 20 000/mm3. The direct Coomb’s test, LE cell test and Elisa for HIV were negative.

Se revisa elconcepto de impulsos irresistibles sistemáticos, la neurobiología y tratamiento de la impulsividad, y la relación deésta con los denominados trastornos del espectro obsesivo-compulsivo. Por último, se resalta el papel del entornofamiliar y social en el desarrollo y pronóstico del cuadro clínico de las pacientes.(Rev Neuropsiquiatr 2010;73:110-117).
