BACKGROUND Balloon sinus dilation (BSD) is an increasingly used tool in endoscopic sinus surgery (ESS). The tissue-sparing nature of the instrumentation allows for properly selected patients to undergo office-based procedures under local anesthesia. METHODS This was an Institutional Review Board (IRB)-approved, prospective, 14-center trial. Patients (n = 203) requiring ESS for medically refra...

The object of this study is to define the part played by maternal iron-deficiency anaemia in the pathogenesis of iron deficiency anaemia in infancy, a condition commonly found in Cape Town (Lanzkowsky and McKenzie, 1959; Lanzkowsky, 1959 and 1960a). A number of early reports on the effect of maternal iron-deficiency anaemia on the newborn have indicated that maternal anaemia does not cause anae...

The maximum rate at which a synaptic link could theoretically transmit information depends on the type of coding used. In a binary modulation system it depends chiefly on the relaxation time, and the limiting capacity equals the maximum attainable impulse rate. In a system using pulse-interval modulation, temporal precision may be a more important limiting factor. It is shown that in a number o...
