A new congenital syndrome characterized by the simultaneous failure of control of ventilation (Ondine's curse) and intestinal motility (Hirschsprung's disease) is reported in three infants, all of whom died in the first few months of life; two were siblings. Detailed studies in one also revealed markedly decreased esophageal motility and abnormal control of(More)
Twenty QT intervals selected at random from the middle periods of rapid eye movement (REM) and quiet sleep were measured in 12 normal infants studied at 2 weeks and 1, 2, 3, and 4 months of life. A digitizing system, consisting of a precision rotational potentiometer mounted on a pair of calipers and an A/D converter, was used for measurements. An accuracy(More)
The QT interval was measured in 12 normal and 7 aborted sudden infant death syndrome (SIDS) infants in rapid eye movement (REM) and quiet sleep at monthly intervals through the age of 4 months. An accuracy of better than 2 msec was assured by high resolution of the digitized signal and calibration of each QT measurement with an accurately generated time(More)
The relationship of beat-to-beat heart rate variability (delta RR) and instantaneous heart rate was studied in eight normal infants while asleep during the first four months of life. The sleep state (REM or quiet) was determined using neurophysiologic and behavioral criteria. The results of regression analyses indicated that the delta RR values were(More)
Anecdotal evidence suggests there is a significant amount of aggressive behavior directed at nursing home personnel by residents' family members. This exploratory study describes a random sample survey of 70 Florida nursing homes. Administrators reported 1,193 acts of verbal aggression and 13 acts of physical aggression for a 6-month period. Dissatisfaction(More)
In this paper we determine the group of endotrivial modules for certain symmetric and alternating groups in characteristic p. If p = 2, then the group is generated by the class of Ω n (k) except in a few low degrees. If p > 2, then the group is only determined for degrees less than p 2. In these cases we show that there are several Young modules which are(More)
The Dade group D(P) of a finite p-group P , formed by equivalence classes of endo-permutation modules, is a finitely generated abelian group. Its torsion-free rank equals the number of conjugacy classes of non-cyclic subgroups of P and it is conjectured that every non-trivial element of its torsion subgroup D t (P) has order 2, (or also 4, in case p = 2).(More)
