background: nitrous oxide (n 2 o) is the oldest anesthetic in routine clinical use and its occupational exposure is under regulation by many countries. as studies are lacking to demonstrate the status of nitrous oxide levels in operating and recovery rooms of iranian hospitals, we aimed to study its level in teaching hospitals of tehran university of medical sciences. methods: during a 6-month ...

background: we evaluated the diagnostic value of electroencephalography (eeg), video-eeg monitoring (vem) and magnetic resonance imaging (mri) of the brain with epilepsy protocol in patients with complex partial epilepsy. methods: forty-two consecutive patients underwent complete neurological examination, eeg, and mri with a modified epilepsy protocol. a subset of these patients (n = 29) also u...

one of the new technologies in the field of health is wearable biosensor, which provides vital signs monitoring of patients, athletes,premature infants, children, psychiatric patients, people who need long-term care, elderly, and people in impassable regions far from health and medical services. the aim of this study was to explain features and applications of wearable biosensors in medical ser...

the state of works of art exhibited inside museums can be strongly influenced by indoor air quality, due to chemical activity of gaseous pollutants and particulate matter. for that reason it is important to carry out periodic air quality controls to check if the concentration levels of air pollutants comply with the limits specified by the national laws. in this work we show results obtained in...

Schizophrenia is a common disease, characterized by progressive functional decline exacerbated by psychotic relapses that often result from a lack of full adherence to antipsychotic (APS) medication. Although atypical APS medications do not have clear therapeutic windows, as generally required for therapeutic drug monitoring (TDM), measuring APS plasma levels in the context of a population expe...

Many patients are believed to be at risk of dysrhythmias and are felt to require cardiac monitoring. These patients may not be deemed ill enough to occupy a high dependency or critical care bed and are monitored on general wards. Monitoring policies vary widely not only between institutions, but also between individual medical staff. These variations occur due to differing availability of resou...

This paper will present a focused and personal history of physiologic monitoring, beginning with the discovery of modern anesthesia and its development from a technical practice to a scientific discipline. Emphasis will be on the essence of monitoring in the anesthesia evolution, and this work will attempt to answer the question of how to evaluate the impact of monitoring on patient outcome. Un...

Based on a previously derived population pharmacokinetic model, a novel neonatal amikacin dosing regimen was developed. The aim of the current study was to prospectively evaluate this dosing regimen. First, early (before and after second dose) therapeutic drug monitoring (TDM) observations were evaluated for achieving target trough (<3 mg/liter) and peak (>24 mg/liter) levels. Second, all obser...

In many industrial and non-industrial applications the quality of a process or product is characterized by a relationship between a response variable and one or more explanatory variables. This relationship is referred to as profile. In the past decade, profile monitoring has been extensively studied under the normal response variable, but it has paid a little attention to the profile with the ...

OBJECTIVES To examine the association of risk factors, age, gender, and earlier opioid requirement with the rate of dose escalation in long-term opioid therapy. METHODS This is a retrospective cohort study of 1,922 individuals identified from California's prescription drug monitoring program database who continuously used opioids from 1999 to 2007. A linear mixed-effects model was used to exa...
