The clinical and pathologic findings of a case of cystic partially differentiated nephroblastoma in a 5-month-old boy is reported. We believe that it probably represents the differentiated counterpart of nephroblastoma. After nephrectomy, the child was given a short course single cytotoxic therapy with vincristine for 6 months.

Sleep behavior between 1/2 and 5 years in 320 Swiss children of the first Zurich longitudinal study is reported. The average length of night sleep between 1/2 and 5 years was 11 to 12 hours. Day sleep was noted in 96% of the children between 6 and 24 months, and in 20% at age 5. ⋯ Evening wakefulness was observed in 16% and night waking in 40 to 50% of all children. 18% woke up at least once each night. Night wakening between 2 and 5 years was positively correlated. In about half of the children with evening wakefulness and/or night wakening these sleep behaviors were considered as abnormal by the mothers.

Twenty-eight children were diagnosed as having dermatomyositis (DM) on the basis of the criteria of Bohan and Peter. Ten of the 28 children developed calcinosis. ⋯ It persisted for a long time beyond the remission of the active muscle symptoms without tendency to spontaneous resolution. Long-term follow-up data substantiate calcinosis as the most frequent and the most serious sequela in this series of childhood DM.
