    Notes: Abstract We examined 14 children aged 28 days to 12.7 years with encephalitis by CT or MRI. Of the patients examined by CT 58% had a normal first scan, whereas all MRI investigations demonstrated abnormalities. The clinical features correlated with several MRI investigations. On MRI herpes (HSV) encephalitis started in the medial temporal lobe and encephalomalacia developed within a few weeks. All patients had a follow-up examination 0.5 to 6.5 years after the acute phase. MRI revealed abnormalities in 13 of the 14 children; one boy, with lesions in only the white matter, had a normal follow-up MRI. Even with immediate, optimal therapy the children demonstrated severe parenchymal abnormalities. Signal abnormalities seen in the acute phase of the disease were likely to persist. In children with HSV encephalitis atypical lesions in different areas were seen.

    Notes: Abstract  The translocation t(4;11)(q21;q23) is one of the most common specific chromosomal aberrations in acute lymphoblastic leukemia (ALL), occurring in 2% of childhood and in 5–6% of adult cases. Especially in adults, the t(4;11) is associated with a poor prognosis. In order to determine the significance of clonal chromosome aberrations that occur in addition to t(4;11), we studied the karyotypes and clinical courses of 23 patients with acute lymphoblastic leukemia and a translocation t(4;11)(q21;q23). Additional clonal chromosome aberrations were found in ten patients. An isochromosome i(7)(q10) and a trisomy 6 were observed most frequently as secondary anomalies. Clonal evolution was detected in four of six patients analyzed at diagnosis as well as at relapse. With treatment carried out according to modern risk-adapted therapy protocols, no difference in outcome was observed between patients with clonal chromosome aberrations in addition to t(4;11) at diagnosis and those without.
