Comparison of MCNP4C, 4B and 4A Monte Carlo codes when calculating electron therapy depth doses
ABSTRACT Background: accurate methods of radiation therapy dose calculation. There are different Monte Carlo codesfor simulation of photons, electrons and the coupled transport of electrons and photons. MCNPis a general purpose Monte Carlo code that can be used for electron, photon and coupledphoton-electron transport.Monte Carlo simulation of radiation transport is considered to be one of the ...
متن کاملOptimal Anti-infective Drug Doses for Children
OPTIMAL ANTI-INFECTIVE DRUG DOSES FOR CHILDREN Anti-infective agents are among the most commonly prescribed drugs in children. What is considered the optimal dose of an anti-infective agent is determined by how the child handles the drug and the resulting drug concentration in the body (pharmacokinetics, PK) as well as by the effect of the drug on the target pathogen (pharmacodynamics, PD). Amo...
متن کاملErrors by paediatric residents in calculating drug dosages.
BACKGROUND Errors in calculating drug doses in infants and small children can cause morbidity and mortality, especially with agents exhibiting a narrow therapeutic window. A previous study from this institution has detected potential life threatening errors in calculations performed by trainees while writing prescriptions. OBJECTIVES To verify whether the true incidence of trainees' errors in...
متن کاملKétamine à faibles doses : antihyperalgésique, non analgésique Low doses ketamine: antihyperalgesic drug, non-analgesic
Recent data in animal experiments as in clinical trials have clearly reported that pain modulation is related to an equilibrium between antinociceptive and pronociceptive systems. Therefore, the apparent pain level could not only be a consequence of a nociceptive input increase but could also result from a pain sensitization process. Glutamate, via NMDA receptors, plays a major role in the deve...
متن کاملCalculating and justifying total anxiolytic doses of medications for in-office use.
Providing anxiolysis (diminution of anxiety and/or fear) for patients is a popular technique for improving a patient's tolerance of invasive dental procedures. Currently there are no guidelines for helping dentists select the appropriate amount of oral medication for a patient who requires anxiolysis. Besides the availability of inherently safe drugs, pulse oximetry, and emergency equipment, co...
