Estimation Of The Incidence Of A Rare Genetic Disease Through A Two-Tier Mutation Survey, R Chakraborty, M R Srinivasan, S Raskin

Recent attempts to detect mutations involving single base changes or small deletions that are specific to genetic diseases provide an opportunity to develop a two-tier mutation-screening program through which incidence of rare genetic disorders and gene carriers may be precisely estimated. A two-tier survey consists of mutation screening in a sample of patients with specific genetic disorders and in a second sample of newborns from the same population in which mutation frequency is evaluated. We provide the statistical basis for evaluating the incidence of affected and gene carriers in such two-tier mutation-screening surveys, from which the precision of the estimates …


Can An Anesthesia Machine Flush Valve Provide For Effective Jet Ventilation?, S D Gaughan, J L Benumof, G T Ozaki Apr 1993

Can An Anesthesia Machine Flush Valve Provide For Effective Jet Ventilation?, S D Gaughan, J L Benumof, G T Ozaki

Faculty, Staff and Student Publications

Transtracheal jet ventilation (TTJV) using a percutaneously inserted intravenous (IV) catheter for the patient who cannot be ventilated or tracheally intubated or, using a jet stylet for changing endotracheal tubes (ETT) in patients for whom subsequent ventilation and/or tracheal reintubation may be difficult, are extremely valuable therapeutic options. The jet ventilation system must have a sufficiently high pressure-oxygen source to drive oxygen through noncompliant tubing and through relatively small IV catheters and/or jet stylets in order to achieve adequate ventilation and oxygenation. There is no evidence that using the common gas outlet of an anesthesia machine by activating the flush …
