RESUMO
Immune thrombocytopenic purpura is an infrequent yet well-recognized complication of viral infections, such as mumps, rubella, varicella, cytomegalovirus, parvovirus and infectious monunucleosis by Epstein-Barr virus. Some recent studies have described a possible association between Henoch-Schonlein purpura, a non-thrombocytopenic purpura, and seropositivity for Bartonella henselae, but in the literature only sporadic case reports have described a severe immune thrombocytopenic purpura as a complication of Bartonella henselae infection. We report a case of an immunocompetent child with clinical and serological evidence of Bartonella henselae infection presenting with purpura and cervical lymphoadenopathy and treated with intravenous immunoglobulin. The patient obtained a rapid and persistent increase in platelet count and a complete regression of purpura.

Mycoplasma pneumoniae is a common cause of community-acquired pneumonia, but this organism can also affect almost every organ system besides the lung. Neurological manifestations (meningitis, encephalitis, transverse myelitis, Guillain-Barrè syndrome) are the most frequent extrapulmonary complications of Mycoplasma pneumoniae. We report a case of a immunocompetent child affected by encephalitis caused by Mycoplasma pneumoniae.
