PURPOSE To use functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) to investigate visual system development in children being treated for retinoblastoma. METHODS Informed consent was obtained for all participants (N = 42) in this institutional review board-approved study. Participants were imaged with a 1.5-T scanner while(More)
The interaction of d-tubocurarine, pancuronium, or succinylcholine with neomycin, streptomycin, or polymyxin B was investigated using a rat phrenic nerve-hemidiaphragm preparation. All neuromuscular blocking agents (relaxants) mutually potentiated the neuromuscular blocking action of one another; combinations of ineffective concentrations of relaxants and(More)
The effect of calcium channel blockers (Ca-antagonists) on the potency and reversibility of muscle relaxants (MR) was investigated in the in vitro phrenic nerve-hemidiaphragm and in vivo sciatic nerve-tibialis anterior preparation of rats. To increase the relevance of the experimental findings to the clinical situation, the [Ca++] and [Mg++] in vitro were(More)
The action of Ptychodiscus brevis "brevetoxins" T17 and T34 on rat phrenic nerve-stimulated hemidiaphragm contraction is reported. The potency of T34 is greater than the potency of T17, but both cause a complete block of neuromuscular transmission in the nM to pM concentration ranges. Preparations exposed to low concentrations of T17 can recover in the(More)
Emergence agitation (EA) can be a distressing side effect of pediatric anesthesia. We retrospectively reviewed the records of 7 pediatric oncology patients who received low-dose ketamine in conjunction with propofol for total intravenous anesthesia (TIVA) repeatedly for radiation therapy. EA signs were observed in all 7 patients in association with propofol(More)

founded in 1966 by Dr. Bernard Brandstater who coined its famous motto: " For some must watch, while some must sleep " (Hamlet-Act. III, Sc. ii). and gave it the symbol of the poppy flower (Papaver somniferum), it being the first cultivated flower in the Middle East which has given unique service to the suffering humanity for thousands of years.

We have compared rapacuronium 2.5 mg kg-1 (n = 20) with succinylcholine 1.5 mg kg-1 (n = 22) in a multicentre, blinded, randomized study in full-term parturients undergoing elective Caesarean section under general anaesthesia. Thiopental 5 mg kg-1 was given i.v. followed by the neuromuscular blocking agent. Sixty seconds later intubation was performed.(More)
